The transmission mechanism 10 includes a belt and two belt pulleys, which can drive another belt pulley to rotate through a belt by one belt pulley. The right end of the positioning shaft 11 is inserted with a cleaning brush 13. The outer wall brush of the cleaning brush 13 is soft, and the middle of the cleaning brush 13 is hollow and has a light weight, which can satisfy the positioning shaft 11 to support the entire cleaning brush 13. A support frame 12 is fixedly connected to the top of the cleaning rack 1. The inner wall of the bottom end of the cleaning rack 1 is elastically connected to a contact plate 15 through a return spring 14. The bottom end of the contact plate 15 is in the shape of a round tube, which can allow the convex block 6 to squeeze the round tube to make the contact plate 15 move vertically. The right end of the contact plate 15 is fixedly connected to a transmission rack 16. The transmission rack 16 is prior art, which can allow agricultural products to be transported on its surface, and the transmission rack 16 is connected to an external device so that the round rods in the transmission rack 16 can rotate.

[0032] Referring to Figures 4 - 5 , a bidirectional lead screw 17 is penetrated and rotatably connected to the inner wall of the positioning shaft 11. There are two different threads on the bidirectional lead screw 17, which can make the clamping plates 18 approach and separate from each other. Here, it is prior art and will not be elaborated too much. The outer wall of the bidirectional lead screw 17 is provided with clamping plates 18. The clamping plates 18 are slidably connected to the inner wall of the positioning shaft 11. The right end of the clamping plate 18 is in a convex part, which can make the convex part be inserted into the cleaning brush 13. The clamping plate 18 is inserted into the inner side wall of the cleaning brush 13. Corresponding notches are opened on the cleaning brush 13 for the clamping plates 18, such as Figure 5 shown, the two groups of clamping plates 18 are in a separated state, and at this time, the clamping plates 18 are inserted into the inner side wall of the cleaning brush 13.

[0033] Referring to Figures 1 - 3 , the extrusion mechanism includes a disc 5. The disc 5 is fixedly connected to the outer wall of the rotating shaft 4. A convex block 6 is fixedly connected to the top of the disc 5. The convex block 6 is in an inclined plane, which can squeeze the contact plate 15 through the inclined plane to make the contact plate 15 move to the highest point of the convex block 6. The bottom plate 2 is rotatably connected to the outer wall of the connecting shaft 9 through a bracket, such as Figure 2As shown in the figure, there is a bracket on the bottom plate 2 connected to the connecting shaft 9 to ensure the stability of the rotation of the connecting shaft 9. The tops of the disk 5 and the convex block 6 are respectively in contact with the bottom end of the contact plate 15. The left end of the connecting shaft 9 is fixedly connected to one end of the transmission mechanism 10. One pulley is connected to the connecting shaft 9, and the other pulley is connected to the positioning shaft 11. The other end of the transmission mechanism 10 is fixedly connected to the left end of the positioning shaft 11. The contact plate 15 penetrates and is slidably connected to the inner wall of the cleaning rack 1. A notch corresponding to the contact plate 15 is opened on the cleaning rack 1, which can allow the contact plate 15 to move vertically, and the movement track will not deviate. The bottom inner wall of the cleaning rack 1 is fixedly connected to one end of the return spring 14. When the contact plate 15 moves upward, the return spring 14 will be compressed. When resetting, the elastic force of the return spring 14 is used to drive the contact plate 15 to reset. The other end of the return spring 14 is fixedly connected to the top end of the contact plate 15. The positioning shaft 11 penetrates and is rotatably connected to the inner wall of the support frame 12. The transmission rack 16 contacts the inner side wall of the cleaning rack 1. A drying box and a flushing gun are provided on the cleaning rack 1. The drying box and the flushing gun can clean and dry the crops. Since this is prior art, no more details will be described here.

[0034] Working principle: First, when it is necessary to clean crops such as potatoes and carrots, only need to start the external device to make the roller on the transmission rack 16 rotate, and then pour the crops onto the roller and transport them from right to left. At the same time, start the flushing gun to flush its surface. At this time, start the motor 3 to drive the rotating shaft 4, the disk 5, and the convex block 6 to rotate at high speed, so that the convex block 6 squeezes the bottom end of the contact plate 15 to drive the contact plate 15 to drive the transmission rack 16 to move vertically by a certain height. At this time, the return spring 14 is in a compressed state. When the contact plate 15 slides down along the inclined surface of the convex block 6, the reverse elastic force of the return spring 14 is used to drive the contact plate 15 to reset downward, so that the contact plate 15 contacts the top of the disk 5. Repeatedly as above to make the transmission rack 16 vibrate to a certain extent, so that the crops on the roller of the transmission rack 16 are continuously turned over, which is convenient for the flushing gun to flush its surface clean. At the same time, when the rotating shaft 4 rotates, it will drive the first bevel gear 7 to rotate, so that the first bevel gear 7 drives the second bevel gear 8, the connecting shaft 9, the transmission mechanism 10, the positioning shaft 11 and the cleaning brush 13 to rotate, so that the bristles of the cleaning brush 13 rotate clockwise to continuously clean the surface of the crops and improve the cleaning effect of its surface. Finally, let the crops pass through the drying box for drying treatment to complete the cleaning and drying process.

[0035] When it is necessary to replace the cleaning brush 13, just manually rotate the bidirectional lead screw 17 in the reverse direction to make the two sets of clamping plates 18 on the bidirectional lead screw 17 approach each other, separate the clamping plates 18 from the inner side wall notch of the cleaning brush 13, and then remove the cleaning brush 13 from the right end of the positioning shaft 11. When it is necessary to install a new cleaning brush 13, just insert the cleaning brush 13 into the right end of the positioning shaft 11. After the clamping plates 18 coincide with the inner side wall notch of the cleaning brush 13, rotate the bidirectional lead screw 17 clockwise to separate the clamping plates 18 from each other, and make the protruding parts of the clamping plates 18 inserted into the inner wall notch of the cleaning brush 13.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
