The working principle of the hydraulic cylinder self-locking device for the hydraulic driving garbage bin door provided by the invention is as follows:
When the hydraulic oil pump 28 is started during normal opening, oil pressure is established, a person operates the unloading door to open, the two-position four-way valve 27 acts leftwards, pressure oil enters the oil pipe 25 through the two-position four-way valve 27 and the high-pressure oil hose 23 and then enters the lower chamber 21 of the hydraulic cylinder 5 through the self-locking module 29, meanwhile, hydraulic oil in the upper chamber 20 of the hydraulic cylinder 5 flows back to the oil tank 26 through the return pipe 24 due to the action of the two-position four-way valve 27, the hydraulic cylinder 5 moves upwards, and the unloading door opening action is completed;
When the hydraulic oil pump 28 is normally closed, oil pressure is established, a person operates the discharge gate to close, the two-position four-way valve 27 acts rightward, pressure oil enters the upper cavity 20 of the hydraulic cylinder 5 through the two-position four-way valve 27, enters the self-locking module 29 all the way and pushes up the one-way valve through the high-pressure oil hose 23, meanwhile, hydraulic oil in the lower cavity 21 of the hydraulic cylinder 5 flows to the oil inlet pipe 25 through the self-locking system one-way valve pushed up and flows back to the oil tank 26 due to the action of the two-position four-way valve 27, the hydraulic cylinder 5 moves downwards, and the normal closing action of the discharge gate is completed.
When the high-pressure oil hose 23 on the oil inlet pipe 25 breaks, the check valve of the self-locking module 29 is not oil-free to push up, the check valve is closed, oil in the lower cavity 21 of the hydraulic cylinder 5 cannot flow out, the hydraulic cylinder 5 cannot act, and the discharging door cannot be closed under the action of self gravity, so that the purpose of self-locking and preventing the discharging door from suddenly falling down is achieved.
When the high-pressure oil hose 23 on the return pipe 24 breaks, the door does not act because the door is in an open state;
Under the action of the limiting spring 31, the piston 33 is in a closed state, hydraulic oil can only flow to the output end oil port 35 through the input end oil port 34, but cannot flow to the input end oil port 34 through the output end oil port 35, when the discharge door needs to be normally closed, as one path of oil from the hydraulic system return pipe 24 enters the pilot oil port 36, under the action of the oil pressure, the piston 33 is jacked up and the check valve core 32 is pushed, so that the check valve core 32 is opened, the oil flow can flow to the input end oil port 34 from the output end oil port 35, and the normal discharge door closing operation is completed;
in the process of descending the lifting door 4, the steel wire rope 18 is driven to slide, the steel wire rope 18 drives the guide rod 19 to descend, when the guide rod 19 descends to the rotating plate 11, the guide rod 19 is guided by the groove 13 and embedded into the groove 13, so that the rotating plate 11 is driven to rotate the driving rod 12, further, the driving rod 12 drives the rotating plate 11 to rotate, the scraping plate 8 embedded into the base table 1 is enabled to rotate from the accommodating cavity 6 to the upper side of the base table 1, after the scraping plate 8 rotates to the upper side of the base table 1, the driving rod 12 is influenced by the maximum torque of the torsion spring 42 and cannot rotate continuously, the continuously moving steel wire rope 18 drives the rotating plate 11 and the driving rod 12 to horizontally move in the accommodating cavity 6 through the guide rod 19 in the groove 13, and accordingly the movable plate 9 and the rotating rod 10 drive the scraping plate 8 to scrape residual garbage on the surface of the base table 1.
