Garbage compression mechanism and control method of side-mounted garbage truck

Abstract

The invention discloses a garbage compressing mechanism of a lateral-loading type garbage vehicle and a control method of the garbage compressing mechanism. The garbage compressing mechanism comprises a filler bin, a push shovel, two push shovel oil cylinders, a rotary coder and a controller. The two push shovel oil cylinders are arranged in a staggered mode, a piston rod of each push shovel oil cylinder is hinged to the push shovel, and a cylinder body of each push shovel oil cylinder is hinged to the inner side of the filler bin. A coder body of the rotary coder is fixed to the filler bin, a mandrel of the rotary coder is fixedly connected with one of the two push shovel oil cylinders, rotates under driving of the push shovel oil cylinder fixed to the mandrel and outputs corresponding pulse data, and the controller is electrically connected with the rotary coder to collect the pulse data output by the rotary coder, and obtains the rotating angle of the corresponding push shovel oil cylinder according to the pulse data to judge the position of the push shovel. The running reliability of the garbage compressing mechanism can be improved, and control over the garbage compressing mechanism is more intelligent.

Description

technical field [0001] The invention relates to the technical field of sanitation machinery and equipment, in particular to a garbage compression mechanism of a side-mounted garbage truck and a control method thereof. Background technique [0002] The compressed garbage truck is a special vehicle for urban sanitation that efficiently collects and transfers garbage. During the process of garbage collection and transfer, it can avoid secondary pollution caused by spilling along the way. Among them, the side-mounted compression garbage truck is one of the compression garbage trucks. It lifts the garbage can through the pull rod to automatically pour the garbage into the filling bin, and pushes and squeezes the garbage to one end of the compartment by pushing the shovel to achieve the purpose of compressing the garbage. . [0003] In the garbage compression mechanism of the existing side-mounted garbage truck, the first proximity switch and the second proximity switch are usual...

AI Technical Summary

Problems solved by technology

[0004] 1. The metal mixed in the garbage will cause the proximity switch to generate false signals, which will directly cause the push shovel to malfunction;

[0005] 2. The working environment of the proximity switch is harsh, and it is not easy to install, debug and maintain;

[0006] 3. It is impossible to know exactly where the shovel is pushed out, which is not conducive to precise control;

[0007] 4. The cost of the pressure sensor is high, and the corresponding programmable controller needs to add an analog acquisition module, which is costly
