Description

Garbage compartment dumping device

technical field

The invention relates to the field of sanitation machinery, in particular to a garbage compartment dumping device used in a garbage truck with detachable compartments.

Background technique

With the rapid development of my country's economy, the amount of garbage produced is also increasing year by year. Therefore, the country pays more and more attention to environmental protection, and the collection and transportation of garbage have also been mentioned on the key work schedule, especially in cities. became the focus of attention. In recent years, cities above the county level in our country have abandoned the open-top transportation method in the past, and gradually transitioned to the current state of separate garbage bins and use compressed garbage trucks for collection and transportation. Garbage trucks are transported in containers It will become the mainstream mode of transportation, and the loading and dumping links in the garbage truck transportation process are an important factor affecting work efficiency, and the working capacity of the garbage unloading device built in the garbage truck is limited due to the limited working space. There is no special device that can greatly improve the efficiency of unloading, dumping, and loading links of garbage trucks at the same time, and its market is vacant.

Contents of the invention

The purpose of the present invention is to overcome the problems of high labor intensity and inaccurate dumping caused by manual or hook dumping of garbage trucks, and propose a garbage truck that integrates the functions of unloading, dumping and loading. pouring device.

The technical scheme adopted in the present invention is:

The dumping device for garbage carriages of the present invention is mainly composed of a rotary table, a base, a telescopic frame, a rotating gear, a horizontal hydraulic rod, a multi-stage hydraulic arm, a vertical hydraulic rod, and a hydraulic arm sleeve. The multi-stage hydraulic arm can be retracted back and forth and fixed on the hydraulic arm sleeve. The hydraulic arm sleeve can move up and down along the upper guide rail of the turntable. The turntable can rotate around the base through the rotating gear at the lower end. The hook at the front end of the multi-stage hydraulic arm Through these movements, the three-degree-of-freedom movement of the space is realized; the telescopic frame can move back and forth along the guide rail at the lower end of the turntable, and there is a row of arc-shaped grooves at the front end of the telescopic frame to limit the movement of the garbage compartment.

Due to the adoption of the above structure, the hook at the front end of the multi-stage hydraulic arm on the garbage truck compartment dumping device of the present invention can be located at any point within the range of the working space, which reduces the requirement for the garbage truck to stop at a designated position before unloading the compartment.

Due to the adoption of the above structure, when the garbage truck dumping device of the present invention pulls the garbage truck out of the vehicle body, the telescopic frame moves forward to be close to the rear of the vehicle body, and then bears the weight of the garbage truck being pulled out and lifts it up. ; This makes the whole removal process smooth and safe.

A row of arc-shaped grooves at the front end of the telescopic frame can block the wheels or the edge of the box body at the end of the garbage truck after the garbage truck is pulled out to a certain extent, which can provide a support point when the garbage truck is lifted later, and can also Limits the distance the multi-stage hydraulic arm can travel to pull the refuse cart and thereby prevents wear and tear from excessive movement of the unit.

The dumping device for garbage trucks of the present invention has the advantages of being easy to use, time-saving and labor-saving, and can greatly reduce labor intensity and loading and unloading time of garbage trucks. Because its production and maintenance costs are relatively low, and most of the moving parts are driven by hydraulic pressure, it can be used in garbage. Work well in harsh environments such as field.

Detailed ways

All features disclosed in this specification, or steps in all methods or processes disclosed, can be combined in any way, except for mutually exclusive features or steps.

Any feature disclosed in this specification, including any appended claims, abstract and drawings, may, unless expressly stated otherwise, be replaced by alternative features which are equivalent or otherwise serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1, Fig. 2 and Fig. 3, a garbage truck dumping device of the present invention mainly consists of a rotary table 1, a base 2, a motor gear 3, a telescopic frame 4, a rotating gear 5, a horizontal hydraulic rod 6, a multi-stage The hydraulic arm 7, the vertical hydraulic rod 8, the hydraulic arm sleeve 9, and the motor 10 are composed. The turntable 1 is installed on the base 2 through bearings to achieve the purpose of being able to rotate around the base. The outer side of the rotating gear 5 has gear teeth and is fixed on the lower end of the turntable 1. The motor 10 is fixed on the base 2 and can be driven by the motor gear 3. The turntable 1 rotates; the multistage hydraulic arm 7 itself is a telescopic multistage hydraulic rod and has a hook at its front end; Move, and its movement is controlled by a horizontal hydraulic rod 6. The front end of the telescopic frame 4 has an arc-shaped groove, which can cooperate with the bottom wheel of the garbage truck or the edge of the box to achieve the purpose of limiting; It is two guide rails with slide grooves. The two sides of the hydraulic arm sleeve 9 are sliding rails that can cooperate with the guide rails on the upper end of the turntable 1 to slide. The multi-stage hydraulic arm 7 is nested and fixed in the hydraulic arm sleeve 9. The vertical hydraulic rod 8 can push the hydraulic arm sleeve 9 and the multistage hydraulic arm 7 fixed thereto to move up and down. As shown in Figure 4, when the dumping device for garbage trucks needs to unload the garbage trucks, the horizontal hydraulic rod 6 first pushes the telescopic frame 4 to stretch forward to close to the rear of the vehicle body, and then the multi-stage hydraulic arm 7 stretches forward until the hook is just right. For the handle of the garbage truck, the vertical hydraulic rod 8 pushes the hydraulic arm sleeve 9 to lift up, and when the hook at the front end of the multi-stage hydraulic arm 7 passes through the handle of the garbage truck, it stops. The arm 7 pulls the garbage truck back to the lower end of the garbage truck. The wheels at the lower end of the garbage truck are stuck in the groove at the front end of the telescopic frame 4. The multi-stage hydraulic arm 7 and the telescopic frame 4 that bears the weight of the garbage truck pull back together and stop at the designated position. The rear motor 10 rotates and drives the turntable 1 to rotate. The turntable 1 will rotate the dump outlet of the garbage truck to face the garbage pit. Finally, the vertical hydraulic rod 8 pushes the hydraulic arm sleeve 9 to lift and the horizontal hydraulic rod 6 Under the combined effect of pushing the telescopic frame 4 to retract, the garbage compartment is tilted because one side is lifted and the internal garbage is dumped out. After dumping, the same steps are reversed to realize the loading of the garbage compartment.
