Pressure control device of compression refuse collector

Abstract

The invention discloses a pressure control device of a compression refuse collector, belonging to the technical field of refuse collector equipment. The pressure control device comprises a hydraulic pump, a multiple-way directional control valve, a programmable logic controller and a plurality of oil cylinders respectively connected with the multiple-way directional control valve; connection oil paths of the multiple-way directional control valve and all the oil cylinders are respectively provided with a pressure sensor for detecting the oil pressure valve on each connection oil path, and the pressure sensors are electrified and used for sending signals to the programmable logic controller when detecting that the oil pressure on the connection oil paths where the pressure sensors are arranged is up to the set pressure valves of the pressure sensors; and the multiple-way directional control valve is controlled by the programmable logic controller. The conversion of actions of all the oil cylinders is controlled by pressure, the waiting or in-advance phenomenon of the next group of oil cylinders, easily caused by the fact that the finishing time of a certain action is inconsistent with the set time, cannot disappear, the pressure control device is high in degree of automation, and the whole work efficiency of the compression refuse collector is increased.

Description

technical field [0001] The invention belongs to the technical field of garbage truck equipment, and in particular relates to a pressure control device suitable for compression garbage trucks. Background technique [0002] Compressed garbage trucks have the characteristics of fast collection and transportation, flexibility and avoidance of secondary pollution, and have become the main model of sanitation vehicles. Its working task is to use its own compression mechanism to compress the garbage into the interior of the carriage, transport it to the garbage disposal site, and then push the garbage out of the carriage. At present, the compressed garbage trucks in the sanitation market are mainly composed of the following parts: chassis, compartment, push plate mechanism, hopper, filling mechanism, hydraulic pressure, electric control and auxiliary systems, etc. The filling mechanism is equipped with Skateboard and scraper assembly. [0003] Among them, the filling, compression...

AI Technical Summary

Problems solved by technology

Due to the unstable operation of the engine and the fluctuation of the pressure and flow of the gear pump, the extension speed of the oil cylinder changes, and the completion time is inconsistent with the set time, which leads to the waiting or advance phenomenon of the next group of oil cylinder actions, and each mechanism cannot follow the preset Requirements to complete the operation, affecting the efficiency of the vehicle
