Embodiment Construction

[0027] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] It should be noted that the hydraulic control system of the garbage truck in the embodiment of the present invention can ensure the uniformity of the compression density of the garbage in the garbage bin of the entire garbage truck, and avoid the garbage bin due to the uneven density of the garbage inside. The front is light and the rear is heavy, so as to prevent potential safety hazards.

[0029] It should be noted that the hydraulic control system of the garbage truck in the embodiment of the present invention can provide an appropriate garbage compression ratio according to different loading requirements of different users. Adjust the back pressure of the push shovel by adjusting th...

Abstract

The invention provides a hydraulic control system of a garbage truck, the garbage truck and a hydraulic control method of the garbage truck. The hydraulic control system comprises a main oil supply passage, a push shovel oil cylinder, a sliding plate oil cylinder and a first pressure control valve, wherein the push shovel oil cylinder is used for driving a push shovel of the garbage truck to stretch out and draw back; the sliding plate oil cylinder is used for driving a sliding plate of the garbage truck to linearly move in the axis direction of a piston rod of the sliding plate oil cylinder, and the push shovel oil cylinder and the sliding plate oil cylinder are arranged on the main oil supply passage in parallel; an inlet of the first pressure control valve is communicated with a rodless cavity of the push shovel oil cylinder, an outlet of the first pressure control valve is communicated with an oil tank, and the control end of the first pressure control valve is communicated with a driving cavity of the sliding plate oil cylinder; and when the pressure value of the driving cavity of the sliding plate oil cylinder reaches a first preset value, the inlet of the first pressure control valve is communicated with an outlet of the first pressure control valve so as to adjust the pressure of the rodless cavity of the push shovel oil cylinder. According to the technical scheme, the hydraulic control system can adjust the back pressure of the push shovel so as to improve the compaction degree of garbage.

Description

technical field [0001] The invention relates to the technical field of garbage trucks, in particular to a hydraulic control system of a garbage truck, a garbage truck and a hydraulic control method of the garbage truck. Background technique [0002] The compression garbage truck is a special vehicle integrating organic, electric and hydraulic systems. It uses special devices such as carriages, stuffers, slides, push shovels, dumping buckets and feeding mechanisms to realize garbage pouring, crushing or flattening, and strong loading. , Squeeze the garbage into the compartment and compact it, as well as the functions of garbage escaping. The basic working process of the above-mentioned garbage truck is as follows: the feeding mechanism (tipping bucket mechanism, etc.) pours the garbage into the filler, the sliding plate mechanism moves (opening the tipping bucket, going down the sliding plate, closing the tipping bucket, and going up the sliding plate), and the sliding plate ...
