Fuente: WIPO "processing tomato" The tomato seed processing and screening device comprises a supporting frame, a feeding bin, a processing machine box and screening nets, the feeding bin is fixedly installed on the left side of the top of the supporting frame, the processing machine box is fixedly connected to the inner side of the supporting frame, and the screening nets are movably connected to the front side and the rear side of the right side of the inner wall of the processing machine box through shaft pins. Adjusting rods are fixedly connected to the front side and the rear side of the bottom of the left side of the screening net. According to the tomato seed screening device, by arranging the protection pad, the stirring plate can be effectively protected by the protection pad made of a rubber material, so that the stirring rod is prevented from colliding with the stirring plate to generate noise, the stirring plate can be better protected, and the problem that when tomato seeds are screened due to the fact that the tomato seed screening device does not have an anti-blocking function, the stirring plate cannot be blocked is solved. The problems that due to the fact that meshes in the surface of a screening net are small, seeds are prone to blocking the interiors of the meshes, the seeds cannot be screened through the meshes, and the practicability of the screening net is reduced are solved.
