Description

A sand and gravel feeding and conveying device

Technical Field

The present application relates to the technical field of conveying devices, and in particular to a sand and gravel feeding and conveying device.

Background Art

When using a belt conveyor to load sand and gravel, there are various structural forms of belt conveyors, including trough belt conveyors, flat belt conveyors, climbing belt conveyors, tilting belt conveyors, turning belt conveyors, etc. When using a climbing belt conveyor to load sand and gravel, multiple partitions need to be set on the conveyor belt of the climbing belt conveyor to prevent the material from falling when it is transported to the inclined slope. However, the existing climbing belt conveyor partitions are usually fixed when they are set. When the sand and gravel are transported to the inclined position, the partitions move with the conveyor belt and tilt synchronously, and some materials will fall.

Referring to the Chinese patent application document with publication number CN116654529A and publication date August 29, 2023, entitled "A belt conveyor specially used for a large-angle aluminum ash production line", the patent application document includes a base belt, a partition, a paddle and a driving member. When the aluminum ash powder moves to the inclined section of the base belt, the partition is adjusted so that the angle between the partition and the base belt is an acute angle. In this process, the funnel structure formed between the partition and the base belt can prevent the material from being scattered outside the partition during upward transportation.

Referring to the above technical solution, when materials are conveyed at an inclined position, materials between the adjacent first and second partitions may fall freely or be squeezed and dropped during the process of blocking or squeezing the materials with partitions. Therefore, when sand and gravel are conveyed to an inclined position, the partitions are tilted, and some materials will fall due to lack of support. The amount of materials conveyed between the partitions becomes less, and a longer time is required to convey a fixed amount of materials, resulting in reduced material conveying efficiency.

Summary of the invention

In view of this, the present application provides a sand and gravel feeding and conveying device, which is mainly used to solve the problem of material falling and low conveying efficiency when the material is conveyed upward at an angle.

In order to solve the above technical problems, the present application provides a sand and gravel feeding and conveying device, including a conveying frame, a power source and a conveyor belt; two skirts are symmetrically installed on the conveyor belt, and a plurality of U-shaped frames are arranged in an array between the two skirts. A rotating shaft is penetrated through the upper part of the U-shaped frame, and a first partition and a second partition are fixedly installed on the rotating shaft. The second partition is mounted on the rotating shaft through a perforated sleeve, and a block is arranged on the second partition at a 180-degree angle to the first partition. A curved folding plate parallel to the conveying track of the conveyor belt is fixedly installed on the conveying frame, and a lever matched with the curved folding plate is fixedly installed on the second partition. A reset torsion spring is arranged around the end of the rotating shaft, which acts on the second partition to present it vertically upward; a first locking assembly for vertically limiting the first partition is symmetrically installed on the inner side wall of the U-shaped frame, and the interior of the U-shaped frame is a hollow structure and is provided with a second locking assembly for vertically limiting the second partition.

By adopting the above technical scheme, the first locking assembly vertically locks the first partition to ensure that the first partition and the conveyor belt are at a right angle, and the second locking assembly vertically locks the second partition to ensure that the second partition and the first partition are 180 degrees; when the lever is not in contact with the curved folding plate, the torsion of the reset torsion spring always keeps the second partition and the first partition at 180 degrees; when the conveyor belt contacts the U-shaped frame, the second locking assembly and the lower side wall of the curved folding plate, the lock of the second partition by the second locking assembly is cancelled, and the synchronous lever drives the second partition to rotate clockwise. At this time, a U-shaped groove is formed between the conveyor belt, the first partition and the second partition, which can prevent materials from falling during the inclined upward conveying process. At the same time, the U-shaped groove has a large space and can carry more materials.

Optionally, the first locking assembly includes a limit bar, a spring sheet and a locking column, the limit bar is installed on the U-shaped frame, the limit bar is provided with a spring sheet, and two locking columns clamped on the spring sheet are installed on the first partition.

By adopting the above technical solution, the compression spring pushes the first limit rod upward, so that the top of the first limit rod contacts the locking groove, and the second partition is locked. The compression spring allows the first limit rod to have expansion and contraction space inside the U-shaped frame.

Optionally, a flip support rod is installed at the upper end of the curved folding plate, and the flip support rod is used to flip the first partition and the second partition and separate them from the U-shaped frame.

By adopting the above technical solution, when the U-shaped frame is conveyed to the unloading end by the conveyor belt, the second partition and the flip support rod come into contact, and the flip support rod can drive the second partition and the first partition to separate from the U-shaped frame, thereby preventing the angle between the U-shaped frame and the first partition from making it difficult for the material to fall.

Optionally, a base located on the outer side wall of the skirt is symmetrically mounted on the conveyor frame, and a roller abutting against the conveyor belt is mounted on the base.

By adopting the above technical solution, the roller can limit the conveyor belt at the inclined upward corner and assist the conveyor belt transmission.

Optionally, a reset assembly is installed on the conveyor frame and the rotating shaft.

By adopting the above technical solution, when the U-shaped frame, the first partition and the second partition are conveyed to the bottom of the conveyor belt close to the loading end, the reset component resets the first partition to continuously convey the material.

Optionally, the reset assembly includes a gear and teeth, the gear is mounted on the end of the rotating shaft, and the teeth are fixedly mounted on the conveying frame.

1. By dividing the partition into sections and adjusting the angle of the upper partition at the same time, the upper and lower partitions are made to present a certain angle. The grooves formed between the upper and lower partitions and the conveyor belt limit the materials. When the materials are transported upward at an angle, they are prevented from falling. At the same time, the volume between the partitions can be increased, the material conveying amount between adjacent partitions can be increased, and the conveying efficiency can be improved.

2. When the material is transported to the unloading end at a high place, the first partition and the second partition are separated from the conveyor belt by adjusting the angles of the upper partition and the lower partition, thereby avoiding the formation of an angle between the first partition and the second partition and the conveyor belt, which can reduce the material remaining on the conveyor belt.

3. The roller is set at the corner where the conveyor belt is inclined upward, which can limit the conveyor belt at the inclined upward corner and assist the conveyor belt transmission.

DETAILED DESCRIPTION

In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the embodiment of the present application will be clearly and completely described below in conjunction with Figures 1 to 10 of the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

1 , 2 and 5 , the present embodiment provides a sand and gravel feeding and conveying device, including a conveying frame 1 , on which a power source 2 and a conveyor belt 3 are provided.

Two skirts 31 are symmetrically installed on the conveyor belt 3, and a plurality of U-shaped frames 4 are arranged in an array between the two skirts 31. A rotating shaft 42 is penetrated through the upper part of the U-shaped frame 4, and a first partition 43 and a second partition 45 are fixedly installed on the rotating shaft 42. The second partition 45 is sleeved on the rotating shaft 42 through a perforated hole, and a stopper 46 is provided on the second partition 45 at an angle of 180 degrees to the first partition 43. A curved folding plate 47 parallel to the conveying track of the conveyor belt 3 is fixedly installed on the conveying frame 1, and a lever 48 matched with the curved folding plate 47 is fixedly installed on the second partition 45. A reset torsion spring 44 is arranged around the end of the rotating shaft 42 to act on the second partition 45 to present it vertically upward.

A first locking assembly 5 for vertically limiting the first partition 43 is symmetrically mounted on the inner side wall of the U-shaped frame 4 . The interior of the U-shaped frame 4 is a hollow structure and is provided with a second locking assembly 6 for vertically limiting the second partition 45 .

When conveying materials, the first partition 43 is vertically locked on the U-shaped frame 4 by the first locking assembly 5. Driven by the reset torsion spring 44, the second partition 45 and the first partition 43 are 180 degrees; the U-shaped frame 4 moves following the transmission of the conveyor belt 3. When the lever 48 contacts the upper side wall of the curved fold plate 47, the second locking assembly 6 contacts the lower side wall of the curved fold plate 47 and releases the lock on the second partition 45. The curvature of the curved fold plate 47 drives the lever 48 to rotate, and the second partition 45 rotates clockwise synchronously. A U-shaped groove is formed between the conveyor belt 3, the first partition 43 and the second partition 45 to limit the material.

2 , 5 and 7 , the first locking assembly 5 includes a limit strip 51 , a spring sheet 52 and a locking column 53 . The limit strip 51 is mounted on the U-shaped frame 4 , and a spring sheet 52 is provided on the limit strip 51 . Two locking columns 53 clamped on the spring sheet 52 are installed on the first partition plate 43 .

The elasticity of the spring sheet 52 enables the spring sheet 52 to be engaged or disengaged between the two locking posts 53 , so that the first partition plate 43 is uprightly engaged on the U-shaped frame 4 of the conveyor belt 3 .

Referring to Figures 2, 5, 6 and 9, the second locking assembly 6 includes a first limiting rod 61, a second limiting rod 62, a compression spring 63 and a locking groove 64. The second limiting rod 62 is arranged on the side wall of the first limiting rod 61, the compression spring 63 is installed at the bottom of the first limiting rod 61, the outer wall of the U-shaped frame 4 is provided with a vertical groove 41, the second limiting rod 62 moves vertically in the vertical groove 41, and the bottom of the second partition plate 45 is provided with a locking groove 64 for sleeved on the top of the first limiting rod 61.

When the second partition 45 is erected on the first partition 43, the first limiting rod 61, under the action of the elastic force of the compression spring 63, drives the top of the first limiting rod 61 to contact the locking groove 64, thereby locking the second partition 45 vertically upward; when the second limiting rod 62 moves forward following the second locking assembly 6 and contacts the lower side wall of the curved folding plate 47, under the elastic force of the compression spring 63, the second limiting rod 62 moves downward in the vertical groove 41, driving the top of the first limiting rod 61 to disengage from the locking groove 64, thereby canceling the vertical upward locking of the second partition 45.

2 , 5 , 6 , 7 and 10 , a flip support rod 471 is installed at the upper end of the curved folding plate 47 , and the flip support rod 471 is used to flip the first partition plate 43 and the second partition plate 45 and separate them from the U-shaped frame 4 .

When the U-shaped frame 4 is conveyed to the unloading end by the conveyor belt 3, the surface of the second partition 45 contacts the flip support rod 471. Under the obstruction of the block 46, the first partition 43 and the second partition 45 always remain 180 degrees parallel when rotating counterclockwise. The flip support rod 471 drives the second partition 45 and the first partition 43 to rotate around the rotating shaft 42 to separate from the U-shaped frame 4 and parallel to the conveyor belt 3, so that the material on the conveyor belt 3 falls off.

1 and 4 , a base 11 located on the outer side wall of the skirt 31 is symmetrically mounted on the conveyor frame 1 , and a roller 12 abutting against the conveyor belt 3 is mounted on the base 11 .

The conveyor belt 3 rotates under the drive of the power source 2 , and the roller 12 rotates synchronously to assist the conveyor belt 3 in transmission.

1 , 3 , 5 , 7 and 8 , a reset assembly 7 is installed on the conveying frame 1 and the rotating shaft 42 .

The reset assembly 7 causes the first partition plate 43 to be clamped on the first locking assembly 5 to reset it.

1 , 3 , 4 , 5 , 7 and 8 , the reset assembly 7 includes a gear 71 and teeth 72 . The gear 71 is mounted on the end of the rotating shaft 42 , and the teeth 72 is fixedly mounted on the conveying frame 1 .

When the first partition 43 and the second partition 45 are separated from the flip support rod 471, the rotating shaft 42, the first partition 43 and the second partition 45 are transmitted to the bottom of the conveyor belt 3, the gear 71 on the rotating shaft 42 is engaged with the teeth 72 on the conveyor frame 1, and the teeth 72 drive the gear 71 to rotate, and the first partition 43 approaches the first locking assembly 5, and the first locking assembly 5 locks the first partition 43 to reset the first partition 43.

1 and 2 , the power source 2 includes a first motor 21 and a second motor 22 . The first motor 21 is installed at the feeding end of the conveyor belt 3 , and the second motor 22 is installed at the unloading end of the conveyor belt 3 . The first motor 21 and the second motor 22 rotate synchronously.

The first motor 21 and the second motor 22 rotate synchronously, driving the conveyor belt 3 to convey.

The implementation principle of a sand and gravel feeding and conveying device in the embodiment of the present application is:

When conveying materials, the elasticity of the spring sheet 52 enables the spring sheet 52 to be clamped between the two locking columns 53, and the first partition 43 is vertically clamped on the U-shaped frame 4 of the conveyor belt 3. Driven by the reset torsion spring 44, the second partition 45 and the first partition 43 are 180 degrees apart. Under the elastic force of the compression spring 63, the first limiting rod 61 drives the top of the first limiting rod 61 to contact the locking groove 64, thereby locking the second partition 45 vertically upward;

The material falls from the lower hopper between the two skirts 31 and the first partition 43 distributed front and back. When the U-shaped frame 4, the first partition 43 and the second partition 45 move forward under the transmission of the conveyor belt 3, when the U-shaped frame 4 is transmitted to the head end of the curved folding plate 47, the second limiting rod 62 contacts the lower side wall of the curved folding plate 47. Under the action of the elastic force of the reset torsion spring 44, the first limiting rod 61 moves downward, so that the top of the first limiting rod 61 is disengaged from the locking groove 64, and the lock on the second partition 45 is released. At the same time, the lever 48 contacts the upper side wall of the curved folding plate 47, and the second partition 45 rotates clockwise. The conveyor belt 3, the first partition 43 and the second partition 45 form a U-shaped groove shape to limit the material. When the material is transported obliquely upward, it prevents the material from falling, and at the same time increases the volume between the partitions to improve the transportation efficiency.

When the material is conveyed to the discharge end above the conveyor belt 3, the lever 48 disengages from the tail end of the curved fold plate 47, and the reset torsion spring 44 drives the second partition 45 to return to its original position, and the second limit rod 62 simultaneously disengages from the curved fold plate 47, and the compression spring 63 bounces up the first limit rod 61, so that the top of the first limit rod 61 is stuck in the locking groove 64; when the second partition 45 and the flip support rod 471 contact, the flip support rod 471 drives the second partition 45 and the first partition 43 to disengage from the U-shaped frame 4, so that the material on the conveyor belt 3 falls off, reducing the material stuck at the corner of the conveyor belt 3 and the first partition 43.

When the first partition 43 and the second partition 45 are separated from the flip support rod 471, the rotating shaft 42, the first partition 43 and the second partition 45 are transmitted to the bottom of the conveyor belt 3, the gear 71 on the rotating shaft 42 is engaged with the teeth 72 on the conveying frame 1, and the teeth 72 drive the gear 71 to rotate, and the first partition 43 is close to the first locking assembly 5. The first locking assembly 5 locks the first partition 43 to reset the first partition 43, which is convenient for continuous transmission of materials.

In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
