Traction type four-row beet harvester

Abstract

The invention discloses a traction type four-row beet harvester. The traction type four-row beet harvester comprises a rack, an excavating device, a conveying system and a transmission system, whereinthe conveying system comprises a backward conveying device, a lifting device and a loading conveying device; the excavating device comprises an excavating shovel capable of excavating the width of four rows of beets of two film laminating belts, and cutting discs are arranged on the two sides of each film laminating belt; the backward conveying device comprises a first backward conveying chain and a second backward conveying chain; the lifting device comprises a front side upward lifting chain and a rear side upward lifting chain; the loading conveying device comprises a forward conveying chain and a loading conveying chain; a soil guide conveying belt is arranged at the lower part of the forward conveying chain; a first film stripping roller is arranged at the joint of the first backwardconveying chain and the second backward conveying chain; a second film stripping roller is arranged at the joint of the second backward conveying chain and the rear side upward lifting chain; and a third film stripping roller is arranged at the joint of the front side upward lifting chain and the forward conveying chain. The beet harvester is reasonable in structure, low in failure rate, relatively high in beet harvesting efficiency, good in soil shaking and film removing effect and good in beet harvesting quality.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a traction type four-row sugar beet harvester. Background technique [0002] At present, the beet planting method mostly adopts film-covered planting in drip tanks, and two rows of beets are planted in each film-covered belt. In order to improve the efficiency of beet harvesting and reduce the labor intensity of farmers, mechanical harvesters are generally used to harvest beets. [0003] Such as: my country's patent CN206542727U discloses "a kind of sugar beet retractor", which includes a frame, an excavating device, a backward conveying device, a lifting device, a loading conveying device and a transmission system, and its working principle is: the sugar beet is pulled by a tractor The retractor walks along the ridge; the beet root is excavated by the digging device; the beet root is transported to the rear of the machine by the backward conveying device, and some ...

AI Technical Summary

Problems solved by technology

[0004] Its disadvantages are: it can only collect two rows of sugar beets planted with one film-covered belt in one stroke, the collection efficiency is low, and the harvesting cost is high; the stroke of the backward conveying device is short, and the soil is not shaken off cleanly; the film and drip irrigation belt cannot be removed , Mulch film and drip irrigation tape are wrapped around mechanical parts, and mulch film and drip irrigation tape are mixed in the harvested beet tubers, which brings inconvenience to post-processing
