Automatic opening and closing mechanism for rear cover of garbage collection box used for sweeping machine

Abstract

The invention aims to provide an automatic opening and closing mechanism for the back cover of a garbage collection box used for a sweeping machine. The automatic opening and closing mechanism comprises the garbage collection box mounted on a frame and connected through a hinge, a lug at the bottom of the garbage collection box forms hinge connection with the piston rod of a hydraulic cylinder through a hinged shaft II, the lug shaft of the hydraulic cylinder is in hinged connection with a bearing seat fixed on the frame, when the piston rod of the hydraulic cylinder is pushed outwards, the garbage collection box can be overturned backwards around a hinged shaft I, meanwhile, a stabilizing device fixed on the bottom plate of the garbage collection box can also drive the casing on a garbage lifting machine to rotate backwards around a hinged shaft III, and drives a spring pull rod to move rightwards, and further the back cover of the garbage collection box is pushed to turn upwards gradually, so as to completely pour out garbage in the box. According to the invention, automatic opening and closing can be achieved only through a pair of hydraulic cylinder equipment, the structure is simple, and the energy is saved.

Description

technical field [0001] The invention relates to the technical field of sanitation equipment, in particular to an automatic opening and closing mechanism for the rear cover of a garbage collection box for a road sweeper. Background technique [0002] At present, when domestically produced road sweepers unload garbage, the turning of the garbage collection box and the opening and closing of the rear cover are generally controlled by hydraulic cylinders, that is, the main hydraulic cylinder installed at the bottom of the garbage collection box controls the turning of the garbage collection box. , and then the auxiliary hydraulic cylinder arranged on the outer wall of the rear cover controls the opening and closing of the rear cover of the garbage collection box. Since the turning over of the garbage collection box and the opening and closing of the rear cover are controlled by two hydraulic cylinders respectively, two hydraulic cylinders and two hydraulic pipelines need to be s...

AI Technical Summary

Problems solved by technology

Since the turning over of the garbage collection box and the opening and closing of the rear cover are controlled by two hydraulic cylinders respectively, two hydraulic cylinders and two hydraulic pipelines need to be separately provided, resulting in complex structure and high cost; similarly, The tipping of this garbage collection box and the opening of the back cover also need to carry out two operations to realize the removal of the garbage. Similarly, the reset of the garbage collection box and the closing of the back cover also need two operations, so in practice The operation process brings a lot of inconvenience and inconvenience, and structural improvement is needed
