Abstract

The invention discloses a hydraulic system for buffering the stroke tail section of a garbage can hopper. The hydraulic system comprises an oil tank, a hydraulic oil pump, a three-position four-way electromagnetic reversing valve, a superposition type hydraulic control one-way valve, a superposition type one-way throttling valve, a first two-position two-way electromagnetic reversing valve, a second two-position two-way electromagnetic reversing valve, a first hopper oil cylinder, a second hopper oil cylinder, an ascending tail section induction switch and a descending tail section induction switch. According to the hydraulic system, the speed of the ascending and descending processes is ensured, and the working efficiency is guaranteed; and meanwhile, the speed of the ascending tail section and the descending tail section is reduced, and the phenomena that collision impact of the hopper on the ground is caused and a material box is jacked up and pulled forwards are avoided. The hydraulic system is reasonable in design and high in practicability.

Description

technical field [0001] The invention relates to a hydraulic system for buffering, in particular to a hydraulic system for buffering at the end of the stroke of a dustbin hopper. Background technique [0002] At present, there is no buffer decompression and deceleration at the end of the stroke of the upper hopper of the large iron bucket type garbage bin of the domestic garbage compression class. When the hopper is put down to load the garbage, it is in the state that the lower plane is close to the ground; and in order to improve the working efficiency, the rising and falling speed of the hopper is relatively fast. Therefore, this working mode will cause a large collision impact on the structure at the end of the rising and falling stroke of the hopper. At the same time, because the ground conditions of each garbage station are different, there is often a certain stroke when falling to the ground, and the cylinder’s The speed is relatively fast, and it is impossible to sto...
