[0051] See also Figures 1 to 7 This embodiment provides a potato-soil separation device, including a frame 10 and a first conveyor belt 20.

[0052] The frame 10 is arranged on the frame of the harvester. The first conveyor belt 20 is arranged obliquely on the frame 10, and at least two groups of the first conveyor belts 20 are arranged in parallel. Specifically, the lengths of the first conveyor belts 20 can be the same or different. Specifically, the multiple groups of first conveyor belts 20 are distributed in steps, and the first conveyor belts 20 of two adjacent steps can be parallel to each other.

[0053] The lower end of the first conveyor belt 20 is a first blanking end 21. The upper end of the first conveyor belt 20 is a second blanking end 22. After receiving the material, the first conveyor belt 20 transports the material from the first blanking end 21 to the second blanking end 22. The material outputted from the second blanking end 22 of the previous first conveyor belt 20 can fall between the first blanking end 21 and the second blanking end 22 of the next first conveyor belt 20.

[0054] In this embodiment, the material here is a mixture of soil and potatoes obtained after preliminary processing by the harvester. The material is transported and falls onto the first conveyor belt 20. Since the first conveyor belt 20 is inclined, the potatoes roll down from the first drop end 21 of the first conveyor belt 20 along the first conveyor belt 20, and the soil is output to the second drop end 22 along the first conveyor belt 20, thereby achieving potato-soil separation. In addition, some soil is also adhered to the surface of the potatoes in some materials, and when the materials fall onto the first conveyor belt 20, they also collide with it, thereby separating the potatoes from the soil adhered to their surface. By providing at least two groups of first conveyor belts 20, as much potatoes as possible in the material can be separated from the soil.

[0055] In one embodiment, the potato-soil separation device further includes a support frame 30 and a telescopic assembly 40 .

[0056] The support frame 30 is provided corresponding to each group of the first conveyor belts 20, and is used to support the first conveyor belts 20. Specifically, the first conveyor belts 20 are provided on the support frame 30. Two groups of telescopic assemblies 40 are provided corresponding to each support frame 30, and the two groups of telescopic assemblies 40 are symmetrical to each other, and the telescopic assemblies 40 are telescopic. One end of the support frame 30 is rotatably connected to the frame 10, and the other end of the support frame 30 is rotatably connected to the lower end of the corresponding telescopic assembly 40 on both sides, and the upper end of the telescopic assembly 40 is rotatably connected to the frame 10.

[0057] In this embodiment, the height of one end of the support frame 30 compared to the other end thereof can be adjusted by telescoping the telescopic assembly 40, thereby adjusting the inclination angle of the first conveyor belt 20 on the support frame 30. This allows adaptation to soils in different regions. Specifically, after the potatoes are separated from the soil, the soil and potatoes move in opposite directions. When the soil is relatively moist and has small soil particles, the friction between the soil and the first conveyor belt 20 is large, and the inclination angle of the first conveyor belt 20 can be increased, so that the potatoes are separated from the soil more thoroughly, thereby preventing some potatoes from being carried forward by the soil. On the contrary, if the friction between the soil and the first conveyor belt 20 is small, the inclination angle of the first conveyor belt 20 is reduced to prevent the soil from rolling down with the potatoes.

[0058] In one embodiment, two groups of symmetrically arranged telescopic components 40 are further connected to both sides of the end of the support frame 30 (to achieve the aforementioned rotational connection effect between the support frame 30 and the frame 10), and each support frame 30 is connected to the frame 10 through four groups of telescopic components 40. Specifically, the two ends of the support frame 30 are tentatively defined as end A and end B, and both sides of the end A of the support frame 30 are rotationally connected to the lower ends of the two groups of telescopic components 40, and both sides of the end B of the support frame 30 are rotationally connected to the lower ends of the other two groups of telescopic components 40. The upper ends of the four groups of telescopic components 40 are all rotationally connected to the frame 10.

[0059] In this embodiment, four sets of telescopic components 40 are used to adjust the tilt angle of the support frame 30 within a larger range, thereby improving the adaptability of the device.

[0060] In one embodiment, the telescopic assembly 40 includes a connecting head 41 , an outer tube 42 and an inner rod 43 .

[0061] The connector 41 is rotatably connected to the frame 10. The upper end of the outer tube 42 is rotatably connected to the connector 41. The lower end of the inner rod 43 is rotatably connected to the support frame 30, and the upper end of the inner rod 43 is inserted into the outer tube 42 and threadedly connected to the inner wall of the outer tube 42.

[0062] In this embodiment, the outer tube 42 is rotated so that the outer tube 42 moves axially on the inner rod 43 to achieve the telescopic function.

[0063] In one embodiment, the support frame 30 includes two symmetrically arranged support seats 31. A first hole 311 is formed on one of the support seats 31.

[0064] The first conveyor belt 20 includes a roller 23 , a motor 24 and a conveyor belt 25 .

[0065] Two rollers 23 are arranged parallel to each other, and the two ends of the rollers 23 are rotatably connected to the two support seats 31. The motor 24 is connected to one of the support seats 31, and the output end of the motor 24 passes through the first hole 311 and is coaxially connected to the end of the corresponding roller 23. The conveyor belt 25 is arranged around the two rollers 23.

[0066] In one embodiment, the support frame 30 further includes two baffles 32 , which are connected to corresponding support seats 31 , and the two baffles 32 are respectively located on both sides of the first conveyor belt 20 .

[0067] In this embodiment, the material falls onto the first conveyor belt 20 and is blocked by the baffles 32 on both sides, thereby preventing the material from slipping off the two sides of the first conveyor belt 20 .

[0068] In one embodiment, the potato-soil separation device further includes a guide member 50, on which a guide groove 51 is provided, and the guide groove 51 is used to receive the material (potato) outputted from at least one first drop end 21. Specifically, the guide groove 51 is located directly below the projection of all first conveyor belts 20, and the guide groove 51 can guide the received material from the ends of multiple first conveyor belts 20 to the middle, thereby concentrating the material for subsequent transportation. Specifically, the guide member 50 can be surrounded by four plates, and the lower end of the guide groove 51 is open.

[0069] In this embodiment, the plurality of conventional belts are distributed along a straight line as a whole, and the conveying directions of the first conveyor belts 20 are the same. Figure 2 When the first drop end 21 of the first conveyor belt 20 on the right side drops the potatoes, the potatoes drop to the left, and the first conveyor belt 20 on the left side is still the same, and the dropped potatoes are not concentrated. After the guide member 50 is adopted, the potatoes dropped from the first conveyor belt 20 on the left side move to the right along the guide groove 51, and the potatoes can be concentrated below the middle of all the first conveyor belts 20, which is convenient for subsequent transportation.

[0070] In one embodiment, the potato-soil separation device further includes a second conveyor belt 60 disposed on the frame 10 , the second conveyor belt 60 is located below the guide member 50 and the first conveyor belt 20 , and the second conveyor belt 60 is used to receive the material falling from the guide groove 51 and the first drop end 21 .

[0071] In this embodiment, potatoes fall from the guide groove 51 and the first drop end 21 and are collectively transported away by the second conveyor belt 60 .

[0072] In one embodiment, the second conveyor belt 60 is provided with a panel 61 on both sides, and the panel 61 is connected to the frame 10. The panel 61 is also located on both sides of the first blanking end 21 of the first conveyor belt 20 and the lower end of the guide member 50.

[0073] In this embodiment, the enclosure plate 61 can prevent materials from slipping off the second conveyor belt 60 .

[0074] This embodiment provides a harvester, comprising any one of the above-mentioned potato-soil separation devices.
