Grading type combined harvester for potatoes

Abstract

The invention relates to a grading type combined harvester for potatoes, which comprises a rack (29), wherein a first-grade soil and potato separating and conveying device (6), a stem and stalk separating device, a second-grade soil and potato separating and conveying device (10), a vertical potato piece lifting device, a roll shaft chain type grading device and a main transmission (31) are arranged on the rack (29), land wheels (30) are arranged at the lower part of the rack (29), and a traction device (1) is arranged at the front end; a digging shovel frame assembly is hinged with the rack (29) and controlled by a lifting cylinder (26) for rising and falling the vertical potato piece lifting device comprises a driving wheel (15), a driven wheel (11), guide wheels (14), a drag chain (belt) (12), a scrapping plate (13) and grid bars; a transverse potato piece conveying device comprising a transmission (24), chain barriers (22), a drive wheel and a driven wheel is arranged in the middle of the roll shaft chain type grading device, and a material receiving and bagging device (32) is arranged on one side. The grading type combined harvester adopts a half-suspending tractor, and can complete working procedures of potato digging, separation between soil and potatoes, between stems and stalks and between potatoes and weeds, potato piece grading, bagging and the like once.

Description

technical field [0001] The invention relates to the technical field of equipment capable of one-time combined potato harvesting, in particular to a graded potato combined harvester. Background technique [0002] At present, there are basically two types of potato harvesting machines at home and abroad: one is a small and medium-sized potato excavator, which has a single function. It can only dig, separate, and lay potatoes on the ground in strips, and then pick them up manually. It is labor-consuming and time-consuming, the production efficiency is low, and the labor intensity is still relatively large. One is a large and medium-sized potato combine harvester, which also has a self-storage type and a side-arm output type. The side-arm output type is more commonly used. It is bulky and has a large supporting power. 1. It is difficult to work on the edge of the field, and it is suitable for large-scale operations. At present, there are patent reports on the potato combine har...

[0002] At present, there are basically two types of potato harvesting machines at home and abroad: one is a small and medium-sized potato excavator, which has a single function. It can only dig, separate, and lay potatoes on the ground in strips, and then pick them up manually. Time-consuming and labor-intensive, low production efficiency and high labor intensity

One is a large and medium-sized potato combine harvester, which also has a self-storage type and a side-arm output type. The side-arm output type is more commonly used. It has a large volume and a large supporting power. 1. It is difficult to work on the edge of the field. It is suitable for large-scale operations. Currently, it is suitable for medium-sized fields. There are patent reports on the potato combine harvester that can achieve grading at the same time, but it has not been put into mass production.
