The opposite surface where the grain suction cylinder 1 and the grain outlet 5 are connected is connected to a dust suction port 7. A dust exhaust pipe 9 is provided on the surface of the suction pump 8. The output shaft of the motor 6 is fixedly connected to a plug plate 64. The inner side of the grain suction cylinder 1 is movably connected to a conveying roller 6 1. One end of the conveying roller 61 is movably connected with a connecting rod 62, and the other end of the conveying roller 61 is provided with a slot. The outer surface of the connecting rod 62 is sleeved with a screw sleeve 63. A filter plate 71 is provided on the inner side of the dust suction port 7. The inner side of the dust suction port 7 is connected with a pressure cylinder 72 through a threaded connection. Through the connection between the grain suction cylinder 1 and the grain outlet 5, under the connection between the motor 6 and the insert plate 64, the insert plate 64 and the slot on the conveying roller 61 are plugged in and connected, so as to realize the rotation effect of the conveying roller 61 in the grain suction cylinder 1. Under the connection between the support plate 2 and the connecting block 3, it is convenient for grain to enter through the support plate 2, so as to achieve the conveying effect of grain.

[0024] Furthermore, the motor 6 is connected to the grain suction cylinder 1 through bolts, and the plug plate 64 is plugged into the slot on the surface of the conveying roller 61. The conveying roller 61 is rotatably connected to the grain suction cylinder 1 through the motor 6. The bolt connection between the motor 6 and the grain suction cylinder 1 facilitates the disassembly and assembly of the motor 6, and thus facilitates the disassembly and assembly of the conveying roller 61 in the grain suction cylinder 1. By plugging the slot on the conveying roller 61 and the plug plate 64, the motor 6 can control the rotation of the conveying roller 61 in the grain suction cylinder 1. Under the action of the conveying roller 61, the transportation of grain is facilitated.

[0025] Furthermore, one end of the connecting rod 62 is rotatably connected to the conveying roller 61 through a rotating shaft, and the other end of the connecting rod 62 passes through the surface of the connecting block 3 and is connected to the screw sleeve 63. The connecting block 3 is connected to the end of the grain suction cylinder 1 away from the motor 6 through the support plate 2. Through the rotational connection between the connecting rod 62 and the conveying roller 61, under the connection of the connecting rod 62 and the screw sleeve 63, a limited support effect is achieved on the action position of the conveying roller 61 in the grain suction cylinder 1, and the disassembly and assembly operations of the conveying roller 61 in the grain suction cylinder 1 are facilitated.

[0026] Furthermore, the grain outlet 5 is connected to the grain suction cylinder 1 through a passage, the dust suction port 7 is connected to the grain suction cylinder 1 through a passage, the dust suction port 7 is connected to the suction pump 8 through bolts, the dust exhaust pipe 9 is connected to the dust suction port 7 through the suction pump 8 and the passage, and the grain outlet 5 is connected to the grain suction cylinder 1 through a passage, and under the action of the grain outlet 5 and the conveying roller 61, the discharge effect of the grain is achieved, and through the connection between the dust suction port 7 and the suction pump 8, under the action of the suction pump 8 and the dust exhaust pipe 9, the adsorption and discharge operations of the dust in the grain are completed.

The pressure cylinder 72 is in abutment with the filter plate 71 through the dust suction port 7. Through the connection between the dust suction port 7 and the filter plate 71, under the threaded connection of the pressure cylinder 72 and the dust suction port 7, the pressure cylinder 72 has a pressing and supporting effect on the position of the filter plate 71 in the dust suction port 7. Under the action of the pressure cylinder 72, the disassembly, assembly and replacement operations of the filter plate 71 in the dust suction port 7 are facilitated, thereby avoiding long-term use, which may cause blockage of the filter plate 71 and affect the normal use of the filter plate 71.

[0028] Furthermore, the outer surface of the grain suction cylinder 1 is fixedly connected to a guide rail 10, and a guide groove 11 is provided on the surface of the guide rail 10. A support rod 12 is slidably connected to the inner side of the guide groove 11, and a connecting sleeve 13 is sleeved on the outer surface of the support rod 12. An adjustment groove 41 is provided on the surface of the support frame 4.

[0029] Furthermore, the cross-sections of the guide groove 11 and the support rod 12 are both T-shaped, and the support rod 12 passes through the adjustment groove 41 and is threadedly connected to the connecting sleeve 13. Under the sliding connection between the support rod 12 and the guide groove 11, the connection between the support rod 12 and the connecting sleeve 13 facilitates the adjustment of the working position of the support frame 4 on the guide rail 10. Under the sliding connection between the adjustment groove 41 and the support rod 12, the effective height of the support frame 4 on the grain suction cylinder 1 is changed, thereby improving the scope and performance of the support frame 4 in supporting the grain suction cylinder 1.

[0030] Working principle: When conveying grain, through the connection between the motor 6 and the plug plate 64, and the insertion of the plug plate 64 and the slot on the conveying roller 61, the rotation operation of the conveying roller 61 in the grain suction cylinder 1 is completed. Under the rotation of the conveying roller 61, the grain flows into the grain suction cylinder 1 through the support plate 2. Under the rotation of the conveying roller 61, the conveying operation is completed, and the grain entering the grain suction cylinder 1 is discharged through the grain outlet 5. Under the connection of the dust suction port 7 and the suction pump 8, the dust in the grain is filtered by the filter plate 71 and then discharged in a direction, thereby achieving the dust removal effect.
