Double-ridge peanut combined harvester

Abstract

The invention relates to a double-ridge peanut combined harvester which can simultaneously harvest four rows of peanuts in two ridges. The double-ridge peanut combined harvester is characterized in that a clamping conveying mode implemented by the aid of elastic pressure rod assemblies and clamping chains on a harvest table is matched with devices such as shifting finger belts and elastic pressure plates to realize conveying turning, so that a double-ridge combined conveying form is implemented; a weld holder is movably fixed onto a lower main beam along the axial direction of the lower main beam, the weld holder, a first pulling clamping chain fixedly connected onto the weld holder and assemblies such as the first elastic pressure rod assembly and the fifth elastic pressure rod assembly horizontally move left and right together, and the extension length of a second pressure rod on the second elastic pressure rod assembly is adjusted, so that the second pressure rod and a fifth pressure rod keep connected with each other, and the extension length of the second pressure rod can be manually adjusted according to the distance between the two ridges of peanuts; an oblique conveying mode of peanut seedling vines can be transited into a horizontal conveying mode by the aid of a transitional clamping conveying device, so that the height of the integral harvester is reduced, and the gravity center of the integral harvester is lowered. The double-ridge peanut combined harvester has the advantages that the structure of the peanut combined harvester is greatly optimized, and the universality and the safety of the double-ridge peanut combined harvester are improved.

Description

technical field [0001] The invention relates to a peanut combine harvester, in particular to a peanut combine harvester with two ridges, capable of harvesting peanuts in two ridges and four rows at the same time, and belongs to the technical field of crop harvesting machinery. Background technique [0002] The peanut combine harvester refers to the peanut harvesting machine that continuously completes the operations of digging, separating soil, picking fruit, and cleaning during the peanut harvesting process. [0003] The disclosure date is August 8, 2007, and the Chinese invention patent with application number 200710020357.6 discloses a combined harvester for stem and root crops. Peanut crops belong to a kind of stem and root crops, which can be harvested by using the combine harvester. Figure 39 It is a schematic diagram of the structure of the peanut combine harvester disclosed in this patent. The left end is the head and the right end is the tail. Peanut plants are se...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is: the existing peanut combine harvester has a high center of gravity and low driving safety; the internal structure is complicated and there are many auxiliary devices; Each of the harvesting platforms can only harvest one ridge (two rows) of peanut crops; even if there is a peanut combine harvester that can harvest two ridges (four rows) of peanut crops at the same time, it is also possible to use two sets of harvesting platforms , two sets of counter-roller fruit picking devices and other devices as the price, the cost is almost doubled, and the volume is huge, only one kind of peanuts with a specific ridge distance can be harvested, and the versatility is low
