1 width-limitcutting disc
It mainly consists of a disc knife, a fixed frame, a compression spring, and an adjustment device. The disc knife is not powered and operates by friction. It is mainly used to cut open the surface along the potato ridges and weeds, which is conducive to excavating parts and preventing stems and weeds from winding and blocking on both sides of the machine.

2 Miningcomponent
It mainly consists of a knife holder, a knife shaft, a main shovel, a secondary shovel, and an excavation angle adjustment mechanism, used to excavate potatoes along with the entire width of the soil. At the same time, the secondary shovel can prevent hard objects such as stones from damaging the conveyor chain.

3 Suppression depth limitdevice
It mainly consists of a copying depth limiting wheel, a bracket, and an adjusting mechanism. The copying depth limiting wheel is used to control and adjust the excavation depth of the digging shovel, and make the potatoes and soil loose, which is conducive to the later separation of potatoes and soil.

4 Grille styledeliverSeparation sieveAnd shaking wheel combination
It is mainly composed of toothed tape, steel grating, driving wheel, passive wheel, and shaking wheel. The conveyor belt is driven by a driving wheel, which is made of rubber teeth and meshes well with the steel grating. It has light wear and a long service life; This type of conveying separation screen is reliable and has less damage to potatoes. The shaking wheel can shake and transport the separation screen, improving the separation ability between potatoes and soil.

5 Strip collection device
After separation and cleaning, the potatoes are transported to the back of the machine, and the width of the collecting baffle is adjusted to lay the potatoes on the ground for picking up.
