The unloading bin is fixedly arranged on the equipment rack. A plurality of spiral feeding rollers are evenly arranged in the unloading bin and connected to the equipment rack by bolts. The belt pressing wheel is connected to the equipment rack by bolts and arranged on both sides of the unloading bin. The high-molecular wear-resistant scraper is connected to the equipment rack by bolts. The hydraulic lifting push rod is connected to the equipment rack by bolts. The electric lifting carrier roller is connected to the equipment rack by bolts. The gas locking hopper is arranged on one side of the equipment. The motor is connected to the spiral feeding roller by a snap pin. The motor is connected to the equipment rack by bolts.

[0005] Preferably, the spiral feeding roller is driven by the motor and arranged directly above the coal belt conveyor.

[0006] Preferably, the hydraulic lifting push rod and the intermediate frame of the belt conveyor are connected by bolts, which can drive the equipment rack to move up and down.

[0007] Preferably, the discharge end of the spiral feeding roller is arranged directly above the gas locking hopper. The motor drives the spiral feeding roller to rotate and push the coal to fall into the gas locking hopper after the coal is translated above the gas locking hopper.

[0008] Preferably, the equipment rack drives the belt pressing wheel to press the belt conveyor after being pressed down, and the coal on the belt conveyor is conveyed to the unloading bin by inertia after being thrown onto the high-molecular wear-resistant scraper.

[0009] Preferably, the edge of the high-molecular wear-resistant scraper is perpendicular to the transport direction of the belt conveyor.

[0010] The utility model discloses beneficial effect is: through the even arrangement multiple spiral feeding roller in unloading storehouse, through spiral feeding roller will the coal in unloading storehouse transport to the air lock hopper top and fall to the air lock hopper, the coal conveying process, spiral feeding roller and the friction between the belt, avoid the traditional plough coal ware plough and the belt wear and tear due to the friction of the belt caused by friction of plough; and there is no lateral thrust to the belt conveyor, will not cause the belt conveyor to run deviation.

[0015] The technical scheme of the utility model will be described clearly and completely in combination with the drawings, and obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making the creative labor belong to the range of the utility model protection.

[0016] Such as Figures 1-3The utility model discloses a unilateral spiral feeding formula unloader, including spiral feeding roller 1, equipment frame 2, unloading bin 3, press belt wheel 4, high polymer wear -resistant scraper 5, hydraulic lifting push rod 6, electric lifting carrier roller 7 and lock gas funnel 8, unloading bin 3 is fixedly arranged on equipment frame 2, a plurality of spiral feeding roller 1 evenly is arranged in unloading bin 3, is connected with equipment frame 2 through bolt, press belt wheel 4 is connected with equipment frame 2 through bolt, is arranged in unloading bin 3 both sides, high polymer wear -resistant scraper 5 is connected with equipment frame 2 through bolt, hydraulic lifting push rod 6 is connected with equipment frame 2 through bolt, electric lifting carrier roller 7 is connected with equipment frame 2 through bolt, lock gas funnel 8 is arranged in equipment frame 2 one side, motor 9 is connected with spiral feeding roller 1 through snap pin, motor 9 is connected with equipment frame 2 through bolt.

[0017] In the embodiment, the spiral feeding roller 1 is driven by the motor 9 and arranged directly above the coal belt.
