[0018] Further, a spring is installed on the bearing of the first wheel set, one end of the spring is connected with the bearing, and the other end is connected with the rack.

[0019] By adopting the above technical scheme, the damage of the potatoes caused by vibration during operation of the equipment is reduced by using the buffering effect of the spring, and the separation quality is improved.

[0020] Further, an eccentric hole is formed in the wheel of the first wheel set, and the transmission shaft of the first wheel set is inserted into the eccentric hole.

[0021] By adopting the above technical scheme, the rack can swing up and down during operation, so that the potatoes in the drum screen collide with each other, thereby knocking off the soil attached to the potatoes, and the cleanliness of the potatoes is further improved.
