The 4U-2A potato excavator is suitable for the harvesting of potato and onion, beet, sweet potato, medicinal herbs and other tuber crops. The machine can complete a number of operations such as excavation, lifting and transportation, and placement, etc. in one operation, and can adapt to the special requirements of the heavy soil in northeast China.
Performance characteristics
1. The machine can adapt to the viscous heavy soil, medium clay and sandy loam soil with water content less than 25%. It can be used everywhere and has strong adaptability.
2. The unique excavating shovel can avoid soil accumulation and weeding, and the excavation depth is stable and does not leak digging.
3. Lifting parts are arranged at intervals between the curved bars and the straight bars, and equipped with a lifting chain stirring mechanism, which greatly improves the jitter and separation performance, and the high rate of clear potatoes.
4. The use of a belt-rising transport chain that does not hurt the potatoes, resulting in a low rate of damaged potatoes, can be used to excavate seed potatoes.
5. The use of this machine can save manpower, increase the harvest of potato by more than 10%. After the operation, the soil is finely crushed, which can reduce the cost of turning over the site, thus having significant economic and social benefits.
