Abstract

The invention provides a potato secondary soil screening harvesting cart. The potato secondary soil screening harvesting cart mainly comprises a rack device, a seedling removing device, a digging device, a soil-potato shaking separating delivering device, a spiral roller separating and screening device and a collecting device, so that the potato secondary soil screening harvesting cart becomes a functional harvesting cart integrating seedling removing, soil digging, delivering, separating and harvesting. The harvesting cart can smoothly complete a series of work of seedling removing, soil digging, conveyance, soil screening, potato collecting and the like, and the harvesting efficiency of the potatoes is improved. By means of the potato secondary soil screening harvesting cart, the purposeof harvesting the potatoes and removing seedlings is achieved, most soil can be separated to the ground, the efficiency of separating soil and the potatoes is greatly improved, the potato damaging rate is lower, the soil screening effect is good, the practicability is high, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a potato secondary soil sieving harvester used in conjunction with small and medium-sized four-wheel tractors. Background technique [0002] Potato is a food crop with high nutritional value and market. It is deeply loved by people both abroad and at home. It has the characteristics of high nutritional value, rich yield, easy long-term storage and wide application. [0003] At present, the potato has become one of the five major food crops in our country. It is planted in a wide range in our country. At present, it is spreading all over the country at the rate of increasing the planting area of ​​100,000 hectares every year. However, there are still many problems in the production of potatoes in our country. , such as poor management of farmland, low degree of mechanization, low level of production technology, etc. [0004] The potato harvesting devices commonly u...
