The drying cover is an arc-shaped cover plate with a small hole on the top and a heating wire is installed on the lower surface. The drying cover is horizontally placed on the base. The electric ring conveyor belt is a non-closed circular circulating conveyor belt driven by a motor. The electric ring conveyor belt is horizontally installed in the base. The base is a vertically placed cylindrical structure. The base has four pairs of supporting legs on the bottom surface and is placed on the ground. The material collecting barrel is a trapezoidal barrel structure. The material collecting barrel is placed on the ground, and the opening of the material collecting barrel is located below the end point of the electric ring conveyor belt.

The funnel is a hollow step structure with a large rectangular opening at the top and a small rectangular opening at the bottom. The upper bracket is a structure with a rectangular frame at the top, a hollow square rod in the middle and a crossbeam at the bottom connected by bolts. The hydraulic rod is a vertically placed hydraulic cylinder with a top rod mechanism. The lower bracket is a structure with two solid square rods fixed on the base.
