DETAILED DESCRIPTION

[0024] The application will be described in detail below with reference to the drawings. Embodiment

[0025] The utility model provides a kind of seed drying processing turnover device, as shown in Figure 1 It includes shell. Inner tank 200 for placing seed and turnover assembly 300 for overturning seed inside inner tank 200 are arranged in shell 100. The device further includes first drive assembly 101 connected with inner tank 200 and for driving inner tank 200 to rotate axially, and second drive assembly 102 connected with turnover assembly 300 and for driving turnover assembly 300 to rotate axially in the direction opposite to the rotation direction of inner tank 200 inside inner tank 200. Under the action of first drive assembly 101 and second drive assembly 102, inner tank 200 and turnover assembly 300 will rotate around shaft in the opposite direction, so that the seed in inner tank 200 will keep turning in their movement, avoiding seed accumulation together. The reason why synchronous but different direction rotation is adopted is that single turning mode is easy to cause seed located in bottom layer to be always unaffected by turning and always accumulated below, leading to its deterioration. The different direction rotation of the two can ensure the complete turning of seed, avoiding uneven heating of seed. Moreover, under the condition that inner tank 200 and turnover assembly 300 rotate around shaft in the opposite direction, the rotation speed of inner tank 200 and turnover assembly 300 can be controlled within low speed range. The turning structure in prior art has lower turning efficiency of seed under the same rotation speed. The inner tank 200 and turnover assembly 300 of the utility model can achieve better turning effect of seed at lower rotation speed, and lower rotation speed can reduce the risk of damage to seed and reduce the risk of failure of corresponding motor, while providing seed drying efficiency, reducing cost consumption.

The inner wall of the outer shell 100 is provided with a track 103 for the movement of the plurality of support wheels 201. The outer surface of the inner tank 200 circumscribes the plurality of support wheels 201, so that during the rotation of the inner tank 200 driven by the first driving assembly 100, there is no collision between the inner tank 200 and the outer shell 100, and the efficiency of rotation is improved. It should be noted that the outer surface of the inner tank 200 can also not be provided with support wheels 201, but only be provided with vertical support force by the axial first driving assembly 100, which can also avoid collision with the outer shell 100. The support wheels 201 provided in the present application can effectively reduce the influence of gravity on the first driving assembly 101, and avoid damage, fracture and other situations of the first driving assembly 101 due to excessive load combined with the axial force provided by the rotation thereof. Preferably, the inner wall of the outer shell 100 is provided with a track 103 corresponding to the plurality of support wheels 201. Since the support wheels 201 are arranged in the circumferential direction on the outer surface of the inner tank 200, the track can limit the lateral movement of the support wheels 201, that is, limit the lateral movement of the inner tank 200 in the outer shell 100.
