Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model.

[0016] As Figure 1The utility model discloses a low-dust powder unloading device, including ditch 1, lifting pallet 2, hydraulic lifting mechanism 3, awning 4, spraying device 5, screw feed chute 6 and belt feeder 7, the ditch 1 is set up on the ground, and the hydraulic lifting mechanism 3 is installed in the ditch 1, and the lifting pallet 2 is movably arranged on the upper end of the ditch 1, the lifting pallet 2 includes plate body 201 and fixed hinge 202, the fixed end of fixed hinge 202 is fixedly arranged on the side wall of one end of ditch 1, and one side end of plate body 201 is fixedly connected with the movable end of fixed hinge 202, the lifting pallet 2 is used for parking the vehicle loaded with powder, when unloading, the end of the tail of the vehicle bucket unloading is towards the position of the lifting pallet 2 and fixed hinge 202, the telescopic end of the lifting hydraulic rod 301 of the hydraulic lifting mechanism 3 is hinged with the bottom of plate body 201, the free end of the lifting pallet 2 is lifted by the lifting hydraulic rod 301 of the hydraulic lifting mechanism 3 to make the vehicle parked on the lifting pallet 2 tilt, and then the powder in the vehicle bucket is unloaded by gravity, the awning 4 is arranged above the lifting pallet 2, the spraying device 5 is installed on the top in the awning 4, the spraying device 5 includes the spray pipe 501 arranged in the U type above the lifting pallet 2, and a plurality of spray heads 502 are installed below the spray pipe 501, a large amount of dust is generated when the powder slides from the vehicle bucket during unloading, the spraying device 5 sprays water from the top of the awning 4 to reduce dust, and the awning 4 is a closed space, so that the dust can be prevented from being scattered, the screw feed chute 6 is installed on the side of the ditch 1 with fixed hinge 202, the lower outlet 601 of the screw feed chute 6 is arranged above the belt feeder 7, the powder poured from the vehicle bucket slides into the screw feed chute 6, the screw feed chute 6 conveys the powder to the belt feeder 7, and then the powder is sent to the production workshop or raw material warehouse by the belt feeder 7, so that the whole low-dust unloading process is completed.

[0017] As Figure 2As shown: the hydraulic lifting mechanism 3 includes lifting hydraulic rod 301, horizontal hydraulic rod 302, trolley 303 and slide rail 304, the slide rail 304 is fixedly installed at the bottom of the trench 1, the trolley 303 is reciprocatingly arranged on the slide rail 304, the fixed part of the lifting hydraulic rod 301 is hinged to the top of the trolley 303 through the rotating shaft 305, one horizontal hydraulic rod 302 is installed on each side of the slide rail 304, the fixed part of the horizontal hydraulic rod 302 is fixed to the ground at the bottom of the trench 1, the telescopic end of the horizontal hydraulic rod 302 is hinged to the rotating shaft 305, the horizontal hydraulic rod 302 controls the trolley 303 to reciprocate along the slide rail 304, because the weight of the vehicle is large and the length of the vehicle is long, if a large angle of inclination is needed, the lifting hydraulic rod 301 needs to be arranged close to the free end of the lifting pallet 2, but the closer to the free end of the lifting pallet 2, the longer the length of the lifting hydraulic rod 301 needed, and the stability of the lifting hydraulic rod 301 when bearing pressure is worse, in order to reduce the cost, the horizontal hydraulic rod 302, the trolley 303 and the slide rail 304 are arranged, when the lifting pallet 2 is lowered, the horizontal hydraulic rod 302 controls the trolley 303 to move along the slide rail 304 to the direction away from the free end of the lifting pallet 2, when the lifting pallet 2 is raised, the horizontal hydraulic rod 302 controls the trolley 303 to move to the direction of the free end of the lifting pallet 2, thereby making the lifting pallet 2 raise the same angle, the length of the lifting hydraulic rod 301 needed is relatively short, at the same time, the depth of the trench 1 excavation can be reduced, further reducing the overall construction cost.

[0018] As shown in Figure 3 : the screw conveying chute 6 includes a U-shaped chute 602 with an opening at the top and a screw 603 rotatingly arranged in the U-shaped chute 602, a discharge port 601 is arranged at the bottom of one end of the U-shaped chute 602, the upper edge of the U-shaped chute 602 is flush with the upper edge of the trench 1, when the powder is unloaded, the discharge port of the vehicle hopper at the tail needs to be aligned with the opening above the U-shaped chute 602, most of the powder directly falls into the U-shaped chute 602, the screw 603 rotates to quickly push the material to the discharge port 601, and the part of the powder not falling into the U-shaped chute 602 falls on the ground around, which can be cleaned into the U-shaped chute 602 manually after unloading, and the upper edge of the U-shaped chute 602 is flush with the upper edge of the trench 1, which is convenient for manual cleaning.

[0019] As shown in Figure 4As shown, the dustproof cover plate 8 is further arranged, and the dustproof cover plate 8 is arranged above the position where the fixed hinge 202 is hinged to the plate body 201, the dustproof cover plate 8 is made of soft plate material of rubber or polyethylene material, can be bent and deformed, is arranged above the fixed hinge 202 for preventing powder from invading the position of the hinge to cause jam, the fixed pressing strip 801 is pressed on one side end edge of the dustproof cover plate 8, the through hole 802 is formed on the fixed pressing strip 801 and the dustproof cover plate 8, the fixed bolt 803 passes through the through hole 802 to fix the fixed pressing strip 801 and the one side end edge of the dustproof cover plate 8 on the ground on the side of the ditch 1 provided with the fixed hinge 202, when the plate body 201 is bent and warped upwards, the dustproof cover plate 8 is deformed along, but the dustproof cover plate 8 is still arranged above the position where the fixed hinge 202 is hinged to the plate body 201 as a whole, thereby the effect that powder invades the hinge can be reduced.

[0020] In the description of the present application, it should be explained that the terms "center", "upper", "lower", "front", "rear", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application.
