The invention belongs to the field of feed production, and particularly relates to a raw material stone removing device for the feed production. The problems that material distribution is not uniformduring using an existing stone removing machine, materials are easy to be accumulated on a sieve, the separation efficiency is low, the inclination angle of the sieve is not adjustable and the applicability is poor are solved. According to a scheme, the device comprises a box body, wherein a mounting frame is arranged in the box body, the mounting frame is obliquely arranged, a fixing frame is fixedly connected to the lower end of the mounting frame, a supporting mechanism is connected to the lower end of the fixing frame, a sieve vibrating mechanism is arranged on the inner side of the mounting frame, and a vibrating motor is fixedly arranged at the lower end of the fixing frame. According to the device, the inclination angle of the sieve surface can be flexibly and conveniently adjusted,effective stone removal can be performed on feed with different weight ratios, the effect of stone removal is guaranteed, the feed and the stone are more quickly layered, so that the stone removal efficiency is improved, and the stone removal effect is improved.
