Problems solved by technology

However, when the spinning mechanism is working, the cylinder runs at a faster speed, greater than 0.1 m / s. After the cylinder is in place, the impact sound between the piston and the cylinder is louder, and the reversing impact noise of the hydraulic valve is also louder.
Existing solutions cannot solve the problem of working noise of compression garbage trucks

Abstract

The invention relates to a noise control system and method for a compressed type garbage truck. The method comprises the steps of using a PLC to control states of a hydraulic control valve with controllable flow, a scraper opening control unit, a sliding plate downlink control unit, a scraper closing control unit and a sliding plate upstream control unit, and enabling the operation process of eachcylinder to be slow in speed-fast in speed-slow in speed-in place. The sound of cylinder impact during loading is completely eradicated and the noise is reduced.

Description

technical field [0001] The invention relates to the field of garbage removal and transportation vehicles, in particular to a method for controlling the noise of a rear-mounted compression type garbage truck. Background technique [0002] With the continuous expansion of the integration of urban and rural sanitation, compression garbage trucks have been widely used in recent years due to their advantages such as large compression capacity, good sealing, convenient loading, and high degree of automation. It has become one of the important tools for domestic garbage collection and transportation in my country. The collection of domestic garbage is generally concentrated at around 5:00 in the morning, and most residents in the community are in the sleeping stage. The compressed garbage truck is noisy, which will affect the rest of the residents and easily cause dissatisfaction. [0003] The rear-loading compression truck drives the bucket turning device through the oil cylinder...
