Potato picking and grading combined harvester

Abstract

The invention relates to the technical field of potato harvesting, and discloses a potato picking and grading combined harvester. The combined harvester comprises a vehicle body and a control system;a picking device, a soil potato separating device and a potato block lifting device are arranged on the vehicle body in sequence; the soil potato separating device and the potato block lifting deviceare respectively connected with the control system; the vehicle body is further provided with a potato block grading device and a potato block collecting device; the potato block grading device comprises a plurality of first driving gears with different diameters, a plurality of driven rotating shafts and a plurality of first motors; and the potato block collecting device comprises a plurality ofpairs of belt pulleys, a plurality of belts, a plurality of second motors, a plurality of collecting chutes and an inclined collecting groove. The potato picking and grading combined harvester realizes the integrated operation of potato picking, soil potato separation, potato block grading and potato block collection, and effectively solves the problems of waste of time and energy during the processes of manual picking, sorting and bagging after potatoes are harvested, so that the production efficiency is greatly improved, the labor intensity is reduced, and the harvesting cost is reduced.

Description

technical field [0001] The invention relates to the technical field of potato harvesting, in particular to a potato picking and grading combine harvester. Background technique [0002] Most of the concentrated potato planting areas are in the north of China, and the growth period is only 80-90 days. Gansu is the main potato production area in the country. Harvesting operations cannot be completed before freezing in winter, causing great economic losses to potato growers. Due to the increase in potato production, the harvest period is shortened, and the labor required for potato harvesting accounts for about 40% of the total labor required for production. Therefore, in order to realize The mechanization of potato production must solve the problem of mechanized harvesting. The harvesting process mainly includes digging, separation, picking up, cleaning, grading and bagging and other processes. Nowadays, the harvesting machinery developed by China is basically a separate harves...

[0002] Most of the concentrated potato planting areas are in the north of China, and the growth period is only 80-90 days. Gansu is the main potato production area in the country. Harvesting cannot be completed before freezing in winter, causing great economic losses to potato growers. Due to the increase in potato production, the harvest period is shortened, and the labor required for potato harvesting accounts for about 40% of the total labor required for production. Therefore, in order to realize The mechanization of potato production must solve the problem of mechanized harvesting. The harvesting process mainly includes digging, separation, picking up, cleaning, grading and bagging and other processes. Nowadays, the harvesting machinery developed by China is basically a separate harvesting method and a segmented harvesting method. Complete soil and potato excavation, crushed soil separation, cleaning seedlings and removing impurities, lifting, unloading and potato loading operations. However, with the acceleration of urbanization in China, a large number of young and middle-aged laborers in rural areas have transferred to cities, the rural labor force has decreased, and labor costs have increased. Large-scale large-scale planting, potato harvesters on the market are showing more and more shortcomings. The strip-type potato harvester lays the dug potatoes on the ground, which requires a lot of labor to pick, grade and bag. Picking up is labor-intensive, low in production efficiency, and high in operating costs
