The invention relates to a separation and cleaning device for soil on the surface of potatoes, which comprises the following working procedures:

when the potatoes are required to be cleaned, a worker places the potatoes in the feeding cavity 12 and enables the potatoes to be located on the conveyor belt 14, then the first motor is powered on, the second ball valve 71 is kept in an open state, the first motor is powered on to drive the conveyor belt 14 to move, small-sized potatoes located on the conveyor belt 14 fall onto the temporary storage plate 17 through the hollow holes in the process, large-sized potatoes are driven to move rightwards by the conveyor belt 14, large-sized potatoes pass through the elastic plate 80 to form a queue and move rightwards in sequence, then large-sized potatoes are conveyed into the second processing cavity 24 and fall into the leftmost cleaning block 27, the potatoes located in the cleaning block 27 abut against the upper side face of the brush plate 49 and are surrounded by the first brush plate 43, the potatoes fall into the cleaning block 27 and are detected by the sensor 85, the sensor 85 controls the third motor 25 to be powered on for a certain time, and the disc 26 rotates by one unit, at this time, the cleaning block 27 originally containing the potatoes moves backwards, the second electromagnet 51 in the cleaning block is powered off, when the second electromagnet 51 is powered off, the second electromagnet 51 does not continuously give repulsive force to the top plate 44, at this time, the top plate 44 rotates until the second brush plate 47 abuts against the upper side surface of the potatoes, when the cleaning block 27 originally located on the front side and not containing the potatoes moves to the left limit, the second electromagnet 51 in the cleaning block is powered on and enables the top plate 44 to rotate, and therefore the cleaning block 27 can receive the next potato.

When the disk 26 rotates, the rotating ring 41 rotates due to the meshing relationship between the first gear ring 42 and the second gear ring 53, the rotating ring 41 drives the first brush plate 43 and brushes the ring surface of the potatoes in the first gear ring with the water flowing out of the hose 74, the muddy water seeped from the cleaning block 27 flows into the drainage cavity 28 through the second drainage hole, when the cleaning block 27 with the potatoes is moved to the rearmost side, the first gear ring 42 is separated from the second gear ring 53, the third gear ring 50 is meshed with the third gear ring, the second gear ring 46 is meshed with the first gear ring, the third electromagnet 52 in the cleaning block 27 is electrified, the third electromagnet 52 is electrified to repel the first brush plate 43 and enable the first brush plate 43 to abut against the potatoes to prevent the potatoes from rotating, then the brush disc 49 and the spring disc 45 rotate when the cleaning block 27 rotates, and the spring disc 45 drives the second brush plate 47 to rotate, so that the upper and lower sides of the potatoes in the cleaning block 27 are brushed, the third gear ring 50 and the second gear ring 46 are not engaged with the gear rings after the cleaning block 27 rotates for a certain angle again, the third electromagnet 52 is powered off, then when the cleaning block 27 moves to the right limit, the potatoes cleaned in the cleaning block 27 can drop and be discharged through the second discharge port 55 because the bottom plate 48 loses support.

After a certain time, the first electromagnet 19 is powered on after the potatoes on the upper side of the temporary storage plate 17 are accumulated to a certain degree, at the moment, the temporary storage plate 17 rotates, the potatoes on the temporary storage plate 17 fall on the lower side surface of the first processing cavity 15, the first ball valve 40 is opened at the moment, the first ball valve 40 is closed and the first electromagnet 19 is powered off after a certain time, at the moment, the temporary storage plate 17 rotates and resets, then the second motor 21 drives the first threaded shaft 22 to rotate forwards, at the moment, the cleaning wheel 36 moves rightwards to wash the potatoes in the first processing cavity 15 in the rotating process, and in the process of the forward rotation of the first threaded shaft 22, the second threaded shaft 57 is driven to rotate through the synchronous belt 58, so that the second connecting block 59 moves leftwards, when the connecting block 31 moves to the right limit, the second connecting block 59 moves to the left limit, and at the moment, the mud deposited on the upper side of the filter screen 61 is pushed into the mud storage cavity 62 by the push plate 60, then the first threaded shaft 22 rotates reversely and moves the connecting block 31 leftwards, when the second motor 21 is powered off and the anti-blocking ball valve 29 is opened after the connecting block 31 moves to the left limit, muddy water is discharged through the drainage cavity 28, the electric control shutter 81 is opened after the water in the first treatment cavity 15 is discharged, and when the ball valve 40 is opened and the screw shaft 22 is rotated forward, the potatoes in the processing chamber 15 are swept by the cleaning wheel 36 and discharged through the discharge opening 37, after the connecting block 31 moves for a plurality of cycles and is reset to the left limit, the first ball valve 40, the anti-blocking ball valve 29 and the electric control shutter 81 are closed, and the second motor 21 is powered off, at this time, a round of cleaning work of the small potatoes is completed, and each time the connecting block 31 moves left and right for one cycle, the second connecting block 59 moves left and right for one cycle, so that the soil on the filter screen 61 can be pushed into the soil storage cavity 62.

Compared with the prior art, the invention has the following beneficial effects: the potato cleaning machine can classify potatoes according to the sizes of the potatoes, and can perform different cleaning schemes on the potatoes with different sizes so as to enhance the cleaning effect;

the washing method is adopted to replace the traditional vibration mud removal to carry out mud removal work on large-sized potatoes, so that the vibration damage of the potatoes is reduced, and each potato can be sequentially washed, so that the radiation range of the washing work is enlarged;

the potato water-soil recovery device can recover soil on potatoes and reduce water and soil loss.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
