A fully fed rapeseed combine harvester

Abstract

The invention discloses a full-feeding type oilseed rape combine harvester. The full-feeding type oilseed rape combine harvester comprises a body (1), a power system, a header (2), a walking device (3), a threshing device (4) and a stubble treatment device (5) located in the front of the body (1). The header (2) is arranged at the front end of the body (1) and comprises a set of double-acting transverse cutting knives (6) and vertical cutting knives (7) on the two sides, wherein the transverse cutting knives (6) are located below the front end of the header (2), and the two sets of vertical cutting knives are located on the two sides of the front end of the header (2). According to the harvester, stable operation of the header in the oilseed rape harvesting process is guaranteed, it can be guaranteed that the harvester can effectively harvest upright oilseed rape with various heights, lodged oilseed rape with different heights and oilseed rape with different maturity grades, oilseed rape branches are effectively prevented from winding around the header when way opening operation is conducted in an irregular planting field, adaptability and harvesting capacity of the whole harvester are improved, and it is guaranteed that harvesting operation is smoothly conducted.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a rapeseed combine harvester. Background technique [0002] Due to the tall rapeseed plant, many branches, long pod section, high grass seed ratio, heavy threshing and separation load, and high moisture content of straw, it is not conducive to grass seed separation, and the harvest loss rate is high. Most growers They are more willing to harvest manually, which leads to a low degree of mechanization of rapeseed harvesting in our country. [0003] The rapeseed combine harvester currently used is usually: the full-feed rice-wheat combine harvester is transformed, that is, by lengthening the cutting table, and setting vertical cutting knives and horizontal cutting knives perpendicular to each other in front of the body, wherein the horizontal cutting The knife is located at the front and bottom of the machine body, and the vertical cutting knife is located at one s...

AI Technical Summary

Problems solved by technology

[0004] (1) At the threshing feeding place, the conveying chain plate clamps the rape stalks while threshing, and the gear rod type threshing rollers lead to a high degree of crushing of the rape stalks, resulting in a heavy subsequent separation load and difficult separation of seeds and grasses. Rapeseed straw has a high moisture content and is easy to block the screen

[0005] (2) This combine harvester works better when harvesting vertical plants with a height of less than 1.8 meters and a maturity of 90% to 95% of rapeseed; but when harvesting plants higher than 1.8 meters, the maturity is at 85% or less, or when there is lodging rape, the harvesting effect is poor, especially when harvesting rape cultivated in irregular fields, the straw entanglement is very serious when opening the road, the operation is very smooth, and the maturity of rape is poor. , the removal rate is low, the threshing loss is large, and the screening loss is also large

[0006] (3) The lifting range of the lower cutting knife is small. Not only can it not pass through obstacles such as field ridges smoothly, but it is also very easy to cause dangerous accidents due to the collision of the lower cutting knife with obstacles during the exercise. This kind of harvester is especially not suitable for Sichuan. Planting areas with more hilly areas, and when harvesting, often leave high stubble, which is not conducive to the later cleaning of the planting land
