As shown in fig. 3-4, the stripper plate 7 comprises a rail 71, which is a rectangular frame and is fixed in position; a plurality of support rods 75, which are uniformly fixed on the rail 71; the movable frame 72 is a rectangular frame, is arranged on the track 71, and is connected with the hydraulic oil cylinder 12 at one side and used for reciprocating movement along the track under the action of the hydraulic oil cylinder 12; a plurality of rotating shafts 73 uniformly erected on the movable frame 72, wherein the arrangement direction of each rotating shaft 73 is the same as that of the supporting rod 75; a plurality of seesaws 74 having a plate structure, each of which has a plurality of ventilation holes, one side of each of which is mounted on each of the rotation shafts 73 and is rotatable along the rotation shaft 73, and the other side of each of which is disposed on the top of the support bar 75; when the movable frame 72 reciprocates, the supporting positions of the rocker 74 and the corresponding supporting rod 75 are changed, so that the rocker 74 is changed between a horizontal position and an inclined position, and accordingly, whether to unload materials or not is realized.

The rocker 74 is rotatably connected with the rotating shaft 73, and the rotating shaft 73 is connected with the movable frame 72 and can drive the rocker 74 to rotate; the hydraulic cylinder 12 pushes the movable frame 72, the movable frame 72 drives the rotating shaft 73 and the rocker 74 to move forwards, the supporting arm of force is smaller and smaller while the rocker 74 moves forwards, the rocker 74 moves downwards under the action of gravity until the stroke of the hydraulic cylinder 12 is completely extended, the rocker 74 also moves downwards to be opened to the maximum, and the material falling opening is also the maximum. When closed, the hydraulic ram 12 moves backwards, the moving frame 72 moves backwards, and the rocker 74 supports a larger and larger arm of force until the ram rod is fully retracted until fully closed.

As shown in fig. 1 and 2, the container type wane micro-negative pressure discharging device further comprises a factory building and an air draft system. The factory building is arranged outside the discharging system, and a closed discharging environment is provided. The air draft system comprises an air draft cover 5, the air draft cover 5 is arranged at the top in the factory building, is positioned above the container 1 and is used for absorbing dust generated in the unloading process; the air suction cover 5 is sequentially connected with an air suction pipeline 8, a negative pressure fan 9 and a dust removal device 10.

One set of exhaust system outside factory building 11 of unloading, including the cover 5 of breathing in on the container upper portion of unloading, negative pressure exhaust system has opened before unloading, and the in-process of unloading can produce a large amount of dusts, and under negative pressure fan's suction effect, the dust can be collected to gas collection cover direction to in being taken out dust collecting equipment, the dust is collected and is filtered, and the air discharge is outdoor. The exhaust system extracts dust generated in the loading process, so that the field operation environment is improved, and the pollution to the environment is reduced. As shown in fig. 1 and 2, the bottom of the container 1 is mounted above the service steel platform 2, so that the equipment can be conveniently serviced.

The utility model relates to a container formula wane micro negative pressure discharge apparatus's application method, according to one section or multistage stripper 7 of opening of haulage vehicle 6's length selectivity, the haulage vehicle 6 is packed into in the continuous downstream under the effect of losing gravity to the material. When the vehicle is about to be filled, the hydraulic rod of the hydraulic oil cylinder 12 is controlled to be recovered, the discharging plate 7 is closed, and the discharging work is completed.

Wherein, the hydraulic stem of hydraulic cylinder 12 stretches out, drives movable frame 72, pivot 73 and wane 74 and moves together, and wherein wane 74 breaks away from the supporting role to it that corresponds bracing piece 75 at the in-process that moves, rotates downwards to make stripper 7 open downwards. The hydraulic rods of the hydraulic oil cylinders 12 are retracted to drive the movable frame 72, the rotating shaft 73 and the tilting plate 74 to move in opposite directions, wherein the tilting plate 74 is supported by the corresponding supporting rods 75 to be in a horizontal position in the moving process, so that the discharging plate 7 is closed.

In some embodiments, after the transport vehicle 6 enters different designated areas according to the length, the front and rear doors of the building 11 will automatically close and trigger the photoelectric sensor provided at the door. The photoelectric sensor gives a signal to the controller, the controller gives a control signal to a main motor of the hydraulic station 13 after delaying for a period of time, for example, 10 seconds, the main motor operates to drive the hydraulic oil cylinder 12, and after a period of time, for example, 3 seconds, a signal is given to the electromagnetic directional valve, the electromagnetic directional valve is opened, the hydraulic oil cylinder 12 moves forwards, and unloading is started. The unloading time is set in advance, when the transport carriage is nearly full of materials, the controller disconnects the signal of the electromagnet at the current station, and simultaneously gives a signal to the electromagnet at the other side, the electromagnet at the other side is electrified to act, the hydraulic oil cylinder 12 moves backwards until the backward stroke is finished, and at this time, the unloading opening and closing are finished.

Wherein, the opening of stripper 7 relies on the power that hydraulic system provided, promotes the movable frame 72 of stripper 7 with the hydro-cylinder, and movable frame 72 drives wane 74 and removes, and there is a rigid's bracing piece 75 bottom each stripper 7, and stripper 7 bottom slides on bracing piece 75, and when the migration distance was greater than wane 74 overall length half distance, under the effect of material gravity, wane 74 began to rotate downwards around the center pin of one end, and the unloading begins. As the entire movable frame 72 continues to advance until the hydraulic ram 12 has completed its stroke, the rocker 74 will rotate downward near 90 degrees with the maximum opening and the material will lose support and continue to move downward under the force of gravity for loading. When the vehicle is about to be filled, the hydraulic system is manually controlled, the hydraulic rod of the hydraulic oil cylinder 12 is recovered to drive the movable frame 72 to move reversely, the discharging plate 7 is also closed, and at the moment, all downward weight of the material acts on the discharging plate 7 again to finish discharging work. The process can be manually operated independently and can also be automatically completed.
