Garbage compression power device

Abstract

The invention discloses a garbage compression power device in the technical field of garbage compression. The garbage compression power device comprises an oil tank assembly, a hydraulic valve set anda power assembly, wherein the hydraulic valve set comprises a first three-position four-way electromagnetic valve, a first two-position four-way electromagnetic valve, a second three-position four-way electromagnetic valve and a second two-position four-way electromagnetic valve; an oil port P of the first two-position four-way electromagnetic valve communicates with a first oil pump; an oil portA of the first two-position four-way electromagnetic valve communicates with an oil port P of the first three-position four-way electromagnetic valve; an oil port B of the first two-position four-wayelectromagnetic valve communicates with an oil port P of the second three-position four-way electromagnetic valve; an oil port A of the first three-position four-way electromagnetic valve communicates with a rod cavity of a tipping bucket oil cylinder; and an oil port B of the first three-position four-way electromagnetic valve communicates with a rodless cavity of the tipping bucket oil cylinder; the oil port P of the second three-position four-way electromagnetic valve communicates with a second oil pump through a second oil inlet pipe; the second oil inlet pipe communicates with the oil port B of the first two-position four-way electromagnetic valve; an oil port A of the second three-position four-way electromagnetic valve communicates with an oil port A of the second two-position four-way electromagnetic valve; and an oil port B of the second three-position four-way electromagnetic valve communicates with a rodless cavity of a push-head oil cylinder. The garbage compression powerdevice has the advantages that the pushing speed of the push-head oil cylinder is increased.

Description

technical field [0001] The invention relates to the technical field of garbage compression, in particular to a garbage compression power device. Background technique [0002] With the continuous improvement of people's living standards, more and more garbage is produced. In order to facilitate and quick cleaning, sanitation compression equipment is rapidly popularized. The prior art discloses a double-pump power device for garbage compression, and the application publication number is CN109501376A , the application publication date is 20190322. The device is equipped with a two-position three-way solenoid valve. When the piston rod of the push head cylinder needs to be extended rapidly, the B oil port of the two-position three-way makes the oil discharged from the push head cylinder return to the push head. In the oil cylinder, the piston rod of the push head cylinder is accelerated to elongate rapidly, thereby accelerating the movement of the push head cylinder. Although t...

AI Technical Summary

Problems solved by technology

Although the prior art returns the oil discharged from the pusher oil cylinder back into the pusher oil cylinder to speed up the compression speed of the pusher oil cylinder, there are still the following problems: the oil liquid discharged from the pusher oil cylinder itself pushes it to move, and the pusher The pushing speed of the head cylinder is still limited. When the dump cylinder dumps the garbage into the garbage bin, the push head cylinder cannot quickly push the push plate to compress the garbage in a short time, which not only affects the garbage loading time, but most importantly affects the garbage. Compression effect, resulting in insufficient garbage density and less loading capacity
