[0007] In the above technical scheme, the top cover and the semicircular groove plate of the middle shell are combined and fixed through the flanges and connecting bolts at the ends thereof, the top cover is provided with an opening through which the feeding hopper passes, and the semicircular groove plate is provided with an opening through which the discharge hopper passes.

[0008] In the above technical scheme, the head shell seat and the tail shell seat are fastened on the equipment base through bolts, and the bolt holes for fastening are elliptical holes elongated along the feeding direction.

[0009] In the above technical scheme, the U-shaped vertical plate structure of the head shell seat and the tail shell seat has a depth of not less than 10 cm.

[0010] The beneficial effect of the utility model is that the shell of the screw feeder can be disassembled and replaced without disassembling the screw body and the driving structure, the part prone to wear is replaced conveniently and quickly, the labor operation amount of maintenance is reduced, and the cost of the equipment is not increased.
