It has the characteristics of wide matching power, less investment and quick effect
Scope of application of 4u-2 1390-2 potato excavator: This product is suitable for potato harvest with ridge planting
The soil type is medium loam and sandy loam, and the soil moisture content is 10 ~ 20%
Beyond the above range, the operating performance of the product may change, and all kinds of soil can be used The machine harvests sweet potato about 5 mu - 20 mu per hour

4u-2 1390-2 potato excavator is matched with ≥ 35 HP tractor
It is used for digging potatoes, separating the potato tubers from the soil, so as to separate the potatoes from the roots and reach the ground, so as to facilitate the picking up of potatoes
The working principle of 4u-2 1390-2 potato excavator is driven by the tractor transmission shaft, which adopts hoe and shovel excavation mechanism, grid mesh chain and vibrating screen conveying separation mechanism
The soil and potato tubers are separated through the vibration of the vibrating screen, the soil blocks and soil surface in the soil fall in the gap of the vibrating screen, and the potatoes left on the vibrating screen fall on the land behind through the vibration of the vibrating screen
Potato excavator is mainly composed of suspension connecting device, frame assembly, hoe and shovel device, grid chain and vibrating screen conveying and separation device
