[0033] In further specific embodiments, the outer sleeve 2 is in a cylindrical shape, and the outer wall of the outer sleeve 2 is provided with an inspection door 13 at a position corresponding to the arc-shaped concave spiral blade 4, so as to facilitate the staff to check the arc-shaped concave spiral blade 4 in real time and to carry out regular maintenance on the cleaner.
[0034] The lower ends of the plurality of arc-shaped concave spiral blades 4 are integrally connected with a first impurity outlet channel 6 and a second impurity outlet channel 7, the upper end of the first impurity outlet channel 6 is connected to the end of the arc-shaped concave spiral blade close to the outer sleeve 2, the upper end of the second impurity outlet channel 7 is connected to the end of the arc-shaped concave spiral blade close to the central branch pipe 3, and the included angle between the central axis of the first impurity outlet channel 6 and the central axis of the second impurity outlet channel 7 is between 90° and 180°; and the lower end of the outer sleeve 2 is fixedly connected with a lower grain hopper 8 in communication with the inner cavity of the outer sleeve.
[0035] In further specific embodiments, the upper end and the lower end of the central branch pipe 3 are fixedly connected to the inner wall of the outer sleeve 2 through an upper positioning frame 14 and a lower positioning frame 15, respectively.
[0036] More specifically, as shown in Figure 4 The upper positioning frame 14 and the lower positioning frame 15 have the same structure, and both correspond to a central branch pipe fixing tube 16 located in the middle and n central branch pipe fixing connection rods 17 connected to the outer wall of the central branch pipe fixing tube 16 in a radial manner, the n central branch pipe fixing connection rods 17 are uniformly distributed in a circumferential direction on the outer wall of the central branch pipe fixing tube 16, one end of the central branch pipe fixing connection rod 17 away from the central branch pipe fixing tube 16 is connected to the inner wall of the outer sleeve 2, and the upper end and the lower end of the central branch pipe 3 are fixed in the central branch pipe fixing tube 16 on the corresponding side.

[0041] Firstly, according to the quantity of the cleaned soybeans, the number of the arc-shaped concave spiral blades 4 in the cleaner is selected, generally four pieces, and can be increased to five to six pieces, and each added piece can improve the efficiency by about 20%.
[0042] When the cleaner works, i.e. starts to feed from the upper hopper 9, the position of the adjusting plate 12 on the plate holder 11 is adjusted after feeding to make the material flow reach a proper flow rate. The soybeans flow into the arc concave spiral blade 4 through the lower grain adjusting mechanism 10 at the lower end of the upper hopper, and are separated from the arc concave spiral blade 4 under the action of centrifugal force. The high-quality soybeans flow into the space between the outer sleeve 2 and the internal cleaning mechanism, and flow along the inner wall of the outer sleeve into the lower hopper 8 through the discharge port 20.
