[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] As Figure 1 shown, a material distribution structure for a bran duster includes a bran duster feeding box 1. A feeding pipe 2 is provided at the upper end of the bran duster feeding box. A receiving plate 3 is arranged in the bran duster feeding box. The receiving plate is arranged obliquely. One side of the receiving plate near the lower end is connected to the lower end face of the top plate of the bran duster feeding box through a buffer member 4. The buffer member can be a spring. The other end of the receiving plate is hinged to the bran duster feeding box. A guiding plate 7 is arranged below the receiving plate. The guiding plate is also arranged obliquely. At least two groups of fixing plates 6 are arranged in the bran duster feeding box. The fixing plates are strip-shaped. The guiding plate is slidably connected to the fixing plates. The length direction of the fixing plates and the sliding direction of the guiding plate are in the front-back direction. A material distribution plate 12 is arranged below the guiding plate. The material distribution plate is a plate structure in an existing bran duster. A U-shaped connecting plate can also be arranged below the guiding plate. The fixing plate passes through the connecting plate. The arrangement of the connecting plate further ensures the stability of the reciprocating movement of the guiding plate.

[0016] Preferably, a vertical plate 5 is provided downward from the lower end surface of the top plate of the scalping machine feed box. The vertical plate is hinged to the receiving plate, and baffles 13 are further provided on both the front and rear sides of the receiving plate. The receiving plate is arranged directly below the feed pipe and is connected through the vertical plate, reducing the connection with the front and rear side walls of the box body.

[0017] Further, a fixed motor (not shown in the figure) is provided outside the side wall of the scalping machine feed box. The output end of the fixed motor is connected to a rotating shaft extending into the scalping machine feed box body. The rotating shaft is connected to a cam 8. The cam is arranged below the receiving plate and is used to reciprocally touch the receiving plate. The rotating shaft and the box body can be connected through bearings, thereby ensuring the stable transmission of the rotating shaft. Further, the rotating shaft is also connected to a second rotating shaft through a transmission structure 9, and the transmission structure can be a pulley transmission structure. The second rotating shaft is rotatably connected to the scalping machine box body, and the rotation mode can also be achieved through bearings. A gear 10 is arranged on the second rotating shaft, and a second gear 11 adapted to the gear is provided on the side wall of the scalping machine box body. The second gear is perpendicular to the gear. The second gear can be connected to the box body through a connecting rod, and the second gear and the connecting rod are rotatably connected to each other. A rack (not shown in the figure) is provided on the guide plate, and the rack meshes with the second gear. The length direction of the rack is the same as the length direction of the fixed plate, which is the front-rear direction. The fixed motor is a forward and reverse motor, thereby realizing the reciprocating transmission of the cam and the rack.

[0018] A limiting plate is provided on the side wall of the scalping machine feed box. The limiting plate is arranged on the side close to the lower end above the guide plate, and there is a gap between the limiting plate and the guide plate. The setting of the limiting plate can control the thickness of the material layer of the material falling on the leveling plate.

[0019] The working principle of the present utility model is as follows: The material enters from the feed pipe and falls on the receiving plate. The receiving plate vibrates in the up and down direction to achieve primary material leveling, and then falls on the guide plate. The guide plate moves in the front and rear direction to achieve secondary material leveling, and finally falls on the existing leveling plate to achieve tertiary material leveling, overall ensuring the material leveling effect.

[0020] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
