Multifunctional self-propelled potato combined harvester

Abstract

The invention discloses a multifunctional self-propelled potato combined harvester, and belongs to the technical field of agricultural harvesting machines. The lower part of the front side of the main frame of the combined harvester is provided with an excavating and conveying device, and the output end of the excavating and conveying device is connected with the lower part of a lift conveyer disposed at the front side of the main frame. The upper end of the lift conveyer is connected with the input end of a cleaning mechanism on the top surface of the main frame. The rear end of a sorting platform at the output end of the cleaning mechanism is connected with a blanking warehouse of a bagging mechanism. A conveying bar strip lift conveying chain is disposed around the excavating and conveying device, and the higher end of the conveying bar strip lift conveying chain is provided with a bar stripe jacking roller driven by a power device. An elastic bar strip mechanism is disposed above the bar stripe jacking roller, and extends out to form an elastic curved bar strip pressing the output end of the conveying bar strip lift conveying chain. A groove-type seedling-removing roller which is engaged with the bar stripe jacking roller through axial extension grooves distributed in the peripheral direction is disposed below the bar stripe jacking roller. The combined harvester is very low in probability that seedling stems escape from the combined harvester, enables the seedling stems to be just pulled off from potatoes, and remarkably improves the removal rate of seedling stems.

Description

technical field [0001] The invention relates to a potato combined harvesting device which is suitable for combined harvesting operations such as sweet potatoes, potatoes and other potatoes, such as excavation, removal of impurities, sorting, bagging, etc., and can also be used for combined harvesting of onions, especially a multi-functional A self-propelled potato combine harvester belongs to the technical field of agricultural harvesting machinery. Background technique [0002] Potatoes such as sweet potatoes and potatoes have the characteristics of high ridge planting, lush seedlings, high yield, deep growth, thin skin and tender meat. The planting ridge height is generally above 25cm, and the growth depth of potato pieces can reach about 25-30cm. The width can reach about 30cm. According to the applicant's understanding, the typical structure of the potato crop harvesting machinery in the prior art is disclosed by the Chinese patent application number 200910139566.1.

Problems solved by technology

These broken seedlings and broken stems and turning heads will not only entangle the rotating parts at the back end of the machine, but also bring great inconvenience to the subsequent starch processing quality or variety selection, and fresh potato packaging; for a long time, it has been necessary to rely on manual labor It is very troublesome to break off the main stem and separate the potato pieces

[0004] 2) Since the roots of potato tubers grow under the soil, in places where the soil is slightly sticky, there is a lot of soil sticking to the surface of the tubers, so it is necessary to take measures to remove soil chunks (including the removal of soil chunks that are constantly falling from the potato chunks) during the operation process. The prior art lacks a reliable mechanism to properly address this operational problem
