Anti-garbage-pinching automatic door closing system and control method for split type garbage compression equipment

Abstract

The invention relates to the technical field of environmental sanitation garbage treatment equipment, in particular to an anti-garbage-pinching automatic door closing system and control method for split type garbage compression equipment. The anti-garbage-pinching automatic door closing system for the split type garbage compression equipment comprises a compression head mechanism, a gate opening and closing mechanism and a hydraulic control module, wherein the compression head mechanism comprises a compression head, the hydraulic control module is connected with the compression head mechanismand the gate opening and closing mechanism, is used for driving the compression head mechanism to execute garbage compression operation or driving the gate opening and closing mechanism to execute gate opening and closing operation, and comprises a pressure sensor for acquiring pressure information of a hydraulic system when the compression head squeezes garbage or a gate is closed. According to the system, the compression head mechanism of the compression equipment can be linked with the gate mechanism, a displacement sensor is adopted to accurately control the action path of the compressionhead, so that the gate is tightly attached to the front end of the compression head when closed, and the phenomena of garbage pinching, garbage hanging and the like caused by an overlarge gap betweenthe gate and the compression head when the gate is closed are eradicated.

Description

technical field [0001] The invention relates to the technical field of sanitation garbage processing equipment, in particular to an automatic door closing system and control method for split garbage compression equipment to prevent garbage from being trapped. Background technique [0002] At present, among the garbage disposal equipment in the domestic market, there are mainly two methods to judge the closing of the split garbage compression equipment: one is to rely on the manual operation of the on-site operator, because the entire compression head device and the gate device of the equipment are hidden inside the equipment and cannot be closed. Visually observe the matching gap between the compression head and the gate, and it is impossible to judge the garbage situation at the lower end of the gate when the door is closed and whether there is garbage trapped after closing the door; the second method is to install a limit switch at the matching position between the compress...

Problems solved by technology

[0002] At present, among the garbage disposal equipment in the domestic market, there are mainly two ways to judge the closing of the split garbage compression equipment: one is to rely on the manual operation of the on-site operator, because the entire compression head device and the gate device of the equipment are hidden inside the equipment and cannot be closed. Visually observe the matching gap between the compression head and the gate, and it is impossible to judge the garbage situation at the lower end of the gate when the door is closed and whether there is garbage trapped after the door is closed; the second method is to install a limit switch at the matching position between the compression head and the gate, and then through the CPU Carry out logic control to automatically control the closing of the gate, but the position acquisition of the limit switch is not accurate, and it can only be transmitted point-to-point, and only one position information can be collected at a time, so it is difficult to prevent the phenomenon of garbage trapping after closing the door

Feedback from the actual use of the market shows that the above two methods cannot effectively solve the phenomenon of garbage being trapped after the loading box is closed, which will eventually cause the loading box to affect the appearance of the city during transportation, pollute the clean road surface, and affect the safe driving of other vehicles. Subject to administrative penalties from relevant administrative departments, in severe cases, vehicles will be banned from the road
