Through the contact between the limiting member 602 and the rotating drum 103, the rotation of the rotating drum 103 is restricted to ensure that the rotating member 104 is conveying materials during the device. The second elastic member 603 is provided between the sliding ring 601 and the protective shell 102, and the second elastic member 603 is a spring.

As shown in Figures 1 and 9, the rotating drum 103 is rotationally matched with the rotating member 104. The rotating drum 103 is fixedly connected with the first connecting blocks 701 distributed symmetrically on the left and right, and the rotating member 104 is connected with the second connecting blocks 702 distributed symmetrically on the left and right. , the second connecting block 702 is located above the first connecting block 701. The first connecting block 701 is rotatably connected with a threaded rod 703. The threaded rod 703 is threadedly matched with the adjacent second connecting block 702.

As shown in Figure 7, Figure 10 and Figure 11, the two handles 1031 are slidingly connected with a pressing member 801, and the handle 1031 is rotatably connected with a swinging member 802 that fits the pressing member 801. The rotation point of the swinging member 802 is located on the handle. The upper middle part of 1031 adopts a labor-saving lever mechanism to facilitate the user to easily press the pressing member 801.

When materials with larger particle sizes need to be conveyed, the user controls the terminal drive 201 to push the second connecting plate 202 downward to a height suitable for the work, and swings the six hinged rods 203 and the swing plate 107 to Suitable for the required range of work, increase the gap between the swing plate 107 and the fixed shell 101 so that materials with larger particle sizes can fall downward, and then the user uses a tool to press the slide tube 302 downward onto it. The limit block does not contact the limit groove of the fixed cylinder 105. When the slide cylinder 302 moves downward, the adjacent springs contract. The user uses tools to rotate the slide cylinder 302, the spline rod 301 and the truncated cone-shaped cover 106. The upper parts rotate so that one of the first connecting plates 108 is located below the unloading point of the secondary transport equipment, so that when the material is thrown from the unloading point of the secondary transport equipment, it will fall to the position of the first connecting plate 108 and pass through. The contact between the first connecting plate 108 and the material with a larger particle size buffers the downward force of the material with a larger particle size, so that a large amount of dust will not be generated when the material with a larger particle size collides with the first connecting plate 108 .

After the adjustment of the rotation angle of the first connecting plate 108 is completed, the user releases the tool, and the slide cylinder 302 moves upward and resets under the action of the adjacent spring, so that the limit block on the slide cylinder 302 is re-aligned with the limit groove of the fixed cylinder 105 Contact to limit the rotation of the slide barrel 302 and its upper parts.

After the material with a larger particle size falls into the fixed shell 101, it comes into contact with the sliding part 109 and smashes the sliding part 109 downward. During the downward movement of the sliding part 109, it squeezes the sliding part 109 and the fixed plate 401. The gas between the sliding member 109 and the fixed plate 401 buffers the material with larger particle size and buffers the force of the material with larger particle size falling downward.

When materials with smaller particle sizes need to be conveyed, the user controls the terminal drive 201 to regularly pull and push the second connecting plate 202 upward to a height suitable for the work, and swing the six hinged rods 203 and the swing plate 107 To the required range suitable for the work, reduce the gap between the swing plate 107 and the fixed shell 101 to facilitate the material with smaller particle size to fall downward and prevent the material with smaller particle size from falling downward without restriction. Then the material discharged from the discharge port of the rotating part 104 is unevenly distributed, and then the user uses a tool to rotate the slide tube 302, the spline rod 301, the truncated cone-shaped cover 106 and its upper parts, so that one of the swing plates 107 is located in the second transport position. Below the equipment unloading point, materials with smaller particle sizes are prevented from colliding with the first connecting plate 108, causing the materials with smaller particle sizes to be ejected by the first connecting plate 108.

No matter in the process of transporting materials with smaller particle sizes or materials with larger particle sizes, the fixed shell 101 will be blocked by materials. When the materials in the fixed shell 101 are blocked between the sliding member 109 and the swing plate 107 After a while, the subsequent material continues to fall downward. Under the action of the material continuing to fall downward, the sliding member 109 is squeezed to move downward. During the downward movement of the sliding member 109, the first elastic member 402 contracts. When the sliding member 109 moves downward, the gas and hydraulic oil between the sliding member 109 and the fixed plate 401 are squeezed. After the sliding member 109 moves downward, the gap between the sliding member 109, the swing plate 107 and the first connecting plate 108 is increased. distance, so that the material continues to fall downward from between the sliding part 109, the swing plate 107 and the first connecting plate 108. At this time, the gas between the sliding part 109 and the fixed plate 401 has been squeezed to the extreme state. At this time, through When the sliding member 109 moves downward, the hydraulic oil inside it is squeezed to the position of the eight piston rods 501, and the eight piston rods 501 are squeezed to move toward each other, so that the eight piston rods 501 are inserted into the material, and the eight piston rods 501 are inserted into the material. The material is dredged, and the piston rod 501 squeezes the adjacent spring during movement.

When the eight piston rods 501 move toward each other, through the cooperation of the internal thread groove of the piston rod 501 and the upper limit pin of the adjacent L-shaped rod 503, the eight piston rods 501 and the fixed rod 502 rotate during the relative movement, and Through the rotation of the fixed rod 502, the material is stirred, the distribution of the material is disrupted, and the material is further dredged.

When all the blocked materials fall downward, the sliding member 109 moves upward and resets under the action of the first elastic member 402, and the eight piston rods 501 move back and reset under the action of adjacent springs.

When the position of the discharge port of the rotating member 104 of the device is much higher than the height from the belt conveyor, the user pulls out the limiting rod 704 from the limiting holes of the adjacent first connecting block 701 and the threaded rod 703. to release the rotation limit of the threaded rod 703, and then the user uses a tool to rotate the threaded rod 703, so that the second connecting block 702 and the rotating member 104 move downward, and the discharge port of the rotating member 104 is close to the belt conveyor below. , to shorten the distance between the belt conveyor and the discharge port of the rotating part 104 and prevent the discharge port of the rotating part 104 from being higher than the belt conveyor. After the material from the discharge port of the rotating part 104 falls downward, a small amount of material is scattered to All around.

After the position adjustment of the rotating member 104 is completed, the user re-inserts the limiting rod 704 into the limiting hole of the first connecting block 701 and the threaded rod 703 to restore the rotation limit of the threaded rod 703.

When the rotating part 104 is not rotating, the upper part of the limiting part 602 is in contact with the upper part of the rotating drum 103 to limit the rotation of the rotating drum 103 and the rotating part 104 to ensure that the rotating part 104 does not prevent the rotating part 104 from being transported during the conveying process of the device. Any rotation.

When it is necessary to adjust the rotation angle of the discharge port of the rotating member 104, the user holds the handle 1031 on either side and presses the pressing member 801 on it. The pressing member 801 squeezes the swinging member 802 while moving in the direction of the swinging member 802. When the swing part 802 swings, the rotation point of the swing part 802 is located above the middle part of the handle 1031, and a labor-saving lever mechanism is used to reduce the strength of the user when pressing the pressing part 801, making it easier for the user to press the pressing part 801.

During the swing of the swing member 802, the inner core 804 is stretched and the adjacent torsion spring is tightened. When the inner core 804 is pulled, the sliding ring 601 and the stopper 602 are pulled downward, and the stopper 602 moves downward. During the process, the second elastic member 603 contracts, and the limiting member 602 moves downward and does not contact the rotating drum 103 to release the rotation limit of the rotating drum 103. The user then holds the handle 1031 to adjust the rotation and rotation of the rotating drum 103. The rotation angle of the component 104 is adjusted to adapt the rotating component 104 to various working conditions.

After the user completes adjusting the rotation angle of the rotating member 104, the user releases the pressing member 801, causing the pressing member 801 to break away from the contact with the swinging member 802, and performs reset swing and slide under the action of the torsion spring of the swinging member 802. The ring 601 and the limiting member 602 move upward and reset under the action of the second elastic member 603, and the limiting member 602 restores the rotation limit of the drum 103, and fixes the rotation position of the rotating member 104.
