Harvesting platform of peanut combine harvester

Abstract

The invention relates to a harvesting platform of a peanut combine harvester and belongs to the technical field of agricultural machinery. An upper beam and a lower beam of a rectangular outer framework of the harvesting platform can respectively lock and sleeve the upper end and the lower end of a vertical support frame to form a movable vertical support frame structure; a first clamping and conveying device is mounted on one side of a harvesting platform frame; a left middle conveying chain is mounted on the outer side of the rear end of the first clamping and conveying device; a rear middle section of the left middle conveying chain and a longitudinal section of an L-shaped conveying chain form a third clamping and conveying device; a second clamping and conveying device is mounted on the other side of the harvesting platform frame; an output section of an inner secondary conveying chain and a transverse section of the L-shaped conveying chain form a transverse clamping and conveying device; an outer secondary conveying chain of the second clamping and conveying device and a middle part of the inner secondary conveying chain form a coaxial lockable hinge support structure together with a fixed rotating shaft and a movable rotating shaft with two sides fixed on the harvesting platform outer framework and the vertical support frame via a rotating bearing sleeve respectively. Through the harvesting platform of the peanut combine harvester, the adaptability problems of uneven ridge surface height and non-uniform ridge spacing of peanut cultivation can be properly solved.

Description

technical field [0001] The invention relates to a crop harvesting machine, in particular to a peanut combine harvester harvesting platform, which belongs to the technical field of agricultural machinery. Background technique [0002] For the typical structure of a combine harvester that harvests peanuts on multiple ridges at the same time, see Chinese invention patent 201310280913.9, which discloses a peanut combine harvester with two ridges. Assembly; the harvesting platform includes a frame, and the frame is provided with a horizontal and parallel upper main beam and a lower main beam. The upper main beam is a rotating beam and is connected with the rear frame assembly. On the harvesting table, the elastic pressing rod parts and the clamping chain are used to carry out the clamping and conveying method, and the conveying steering is completed with devices such as the finger belt and the elastic pressing piece, and the form of two ridges combined conveying is realized; and ...

Problems solved by technology

Although this invention optimizes the structure of the peanut combine harvester and improves the versatility and safety, there are two problems to be solved: 1) The left and right distance between the left and right clamping and conveying devices is complex in structure, inconvenient to adjust, and time-consuming and laborious; 2) The left and right clamping and conveying devices of the harvesting table cannot be raised and lowered independently according to the fluctuation of the ridge surface, so a suitable clamping height cannot be guaranteed

[0003] In addition, the two-ridge and four-row full-feed peanut combine harvester disclosed in the Chinese patent application No. 201210516979.9 also fails to solve the problem that the ridge surface of peanut planting has different heights and ridge spacing due to factors such as different regions and varieties. The problem

[0004] The multi-ridge harvester of the above-mentioned prior art cannot be easily adjusted according to the height of the ridge surface and the change of the distance between the ridges, so the adaptability is limited
