The number of brushes 32 should not be too many, four to eight is the best, the number of brushes 32 should be equal to the number of beating plates 38, and alternating settings have the best effect. The end of the brush 32 shaft close to the center of the rotating column 31 is fixedly sleeved with a bevel gear 33, and the groove in the middle of the rotating column 31 is rotatably connected with a rotating rod 34. The outer surface of the rotating rod 34 is fixedly sleeved with evenly distributed bevel gears 35, which are respectively meshed with the horizontally adjacent bevel gears 33. The surface is provided with evenly distributed sockets 37, and the sockets 37 are alternately distributed with the brushes 32. The interior of the sockets 37 is provided with a detachable beating plate 38. The bran brushing mechanism 3 also includes a driving assembly 36, and the driving assembly 36 includes a transmission rod 363, a bevel gear 2 364, a bevel gear 365, a bevel gear 366 and a bevel gear 4 367.

The inner walls of the socket 37 are provided with evenly distributed locking grooves 394, and the number of locking grooves 394 needs to be an even number, six The locking grooves 394 are all plugged into the horizontally adjacent locking blocks 392, and the plug-in assembly 39 also includes a spring 393. The spring 393 is arranged between the two locking blocks 392 located in the same slide groove, and then the motor 361 is turned on by controlling the switch 7. The motor 361 drives the rotating column 31 and the rotating rod 34 to rotate respectively, and the rotating rod 34 drives the bevel gear 35 to rotate, and the transmission bevel gear 33 drives the brush 32 to rotate, so that the brush 32 rotates while following the revolution of the rotating column 31, thereby brushing off the flour attached to the surface of the raw material. At the same time, the beating plate 38 hits the raw material, shakes off the flour on the surface of the raw material, and falls into the discharge hopper 5 through the mesh of the screen drum 2, and finally flows out. Since the beating plate 38 is set at an angle, the raw material will continue to move to the right during the beating process.The pressing block 391 can be pressed downwards by hand at the same time, and the pressing block 391 drives the locking block 392 to slide into the inside of the chute, so that the locking block 392 is retracted into the inside of the chute, and the beating plate 38 can be pulled out. Then the horizontal angle of the beating plate 38 can be reduced, and the corresponding locking groove 394 can be found and inserted into it. At this time, the distance that the beating plate 38 moves the raw material will become larger, and the wheat bran brushing can be completed more quickly. If the beating plate 38 needs maintenance, it can be pulled out in the same way, and the corresponding locking groove 394 can be inserted after the maintenance is completed. The brush 32 rotates while revolving, and the bran brushing effect is better. By cooperating with the locking block 392 and the locking groove 394, the angle of the beating plate 38 is adjusted so that the distance the beating plate 38 moves after beating the bran can be adjusted to adjust the discharge speed. At the same time, the beating plate 38 is easy to disassemble and convenient for maintenance.

[0029] The working principle of a wheat bran brushing machine provided by the present invention is as follows: when threshing wheat bran, the raw materials need to be poured into the interior of the screen drum 2 through the feed pipe 8, and then the motor 361 is turned on by the control switch 7. The motor 361 drives the rotating column 31 and the rotating rod 34 to rotate respectively, and the rotating rod 34 drives the bevel gear 35 to rotate, and the transmission bevel gear 33 drives the brush 32 to rotate, so that the brush 32 rotates while following the revolution of the rotating column 31, thereby brushing off the flour attached to the surface of the raw materials, and at the same time, the beating plate 38 hits the raw materials, shakes off the flour on the surface of the raw materials, and falls into the discharge hopper 5 through the mesh of the screen drum 2, and finally flows out. Since the beating plate 38 is set to an angle, the raw materials will During the beating process, keep moving it to the right until it falls from the slag outlet 4 to the discharge hopper 5 and finally flows out. If there is less flour attached to the surface of the raw material, you can press the pressing block 391 downwards with your hand at the same time. The pressing block 391 drives the locking block 392 to slide into the inside of the chute, so that the locking block 392 shrinks into the inside of the chute, and then you can pull out the beating plate 38, and then adjust the horizontal angle of the beating plate 38 to a smaller level, find the corresponding locking groove 394 and insert it. At this time, the distance that the beating plate 38 moves the raw material will become larger, and the wheat bran can be brushed faster. If the beating plate 38 needs maintenance, you can pull out the beating plate 38 in the same way and insert the corresponding locking groove 394 after the maintenance is completed.

[0030] It is worth noting that the motor 361 disclosed in the above embodiment can be a 110BYGH1.8 two-phase stepper motor, and the control switch 7 is provided with a button corresponding to the motor 361 and controlling its switching.
