Embodiment Construction

[0062] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0063] see figure 1 , the present embodiment is used for the hydraulic system control method of compression garbage truck, comprises the following steps:

[0064] S1. The hydraulic oil tank supplies oil to the slide cylinder and / or scraper cylinder, and drives the piston rod of the slide cylinder and / or scraper cylinder to move;

[0065] S2. The position sensor detects the movement position of the piston rod of the slide cylinder and / or the scraper cylinder;

[0066] S3. In the first stage, when the piston rod of the slide cylinder and / or the scraper cylinder moves from the initial position to the X1 position, the amount of oil supplied to the slide cylinder and / or the scraper cylinder is the first preset value;

[0067] S4. In the ...

Abstract

The invention relates to a hydraulic system control method for a compressed garbage truck, comprising the following steps: a hydraulic oil tank supplies oil to a slide cylinder and / or a scraper cylinder, and drives a piston rod of the slide cylinder and / or scraper cylinder to move; a position sensor Detect the moving position of the piston rod of the slide cylinder and / or the scraper cylinder; in the first stage, when the piston rod of the slide cylinder and / or the scraper cylinder moves from the initial position to the X1 position, the slide cylinder and / or the scraper cylinder The oil supply volume of the board cylinder is the first preset value; in the second stage, when the piston rod of the slide cylinder and / or scraper cylinder moves from the X1 position to the X2 position, the oil supply of the slide cylinder and / or scraper cylinder The amount of oil supplied is the second preset value; in the third stage, when the piston rod of the slide cylinder and / or scraper cylinder moves from the X2 position to the end position, the oil supply to the slide cylinder and / or scraper cylinder is the first Three preset values. The invention can realize the operation performance that can take into account both high-efficiency operation and low noise.

Description

technical field [0001] The invention relates to the technical field of sanitation special vehicles, in particular to a hydraulic system control method and a hydraulic system for compression garbage trucks. Background technique [0002] The compressed garbage truck is a special urban sanitation vehicle that efficiently collects and transfers garbage, and has made outstanding contributions to the improvement of urban environmental sanitation. Its top loading operation device mainly includes scraper, slide plate, push plate, lifting mechanism, etc., and the above components are all driven by the hydraulic system. In order to minimize the labor intensity of sanitation workers and reduce the disturbing impact of vehicles operating in the early morning, high efficiency and low noise are two important parameters for the performance characterization of compression garbage trucks. [0003] In the prior art, the operation efficiency of the compression-filling cycle of the compression...
