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...

[0035] See details figure 1and Figure 4 As an improvement of the above-mentioned first embodiment, the stubble processing device 5 includes a lifting device connected to the header 2, a support arm 8 driven by the lifting device and moving synchronously with it, and the stubble processing device 5 mainly uses Cut the stubble left after the rape stalks are cut by the cutting table 2, wherein the support arms 8 are located on both sides of the body 1, the front end is provided with a cutting knife 9, and the rear ends are connected to the body through the main support shaft 18. 1 connection; the lifting device includes three lugs 10, two connecting rods 11 with elongated holes 14, a pull rod 12 and a steel rope 13, wherein the three lugs 10 are respectively connected to the header 2 and the machine body 1 On the knife rest 55 of the cutting knife 9, one end of the two connecting rods 11 is connected with the lug 10 on the knife rest 55 respectively, and the two long holes 14 a...

Embodiment 3

[0039] See details figure 1 and image 3 , the threshing device 4 in this embodiment includes a primary threshing roller 19 and a secondary threshing roller 20 located in the machine body 1, wherein the primary threshing roller 19 includes a threshing roller shaft 21, a connecting ring 22 and a threshing hub 23. Skeleton, and the grain bar 24 that is connected on this framework, the primary threshing roller 19 of grain bar structure can strengthen the rape threshing effect of the first stage, and reduce the crushing strength of the rape straw in the first stage threshing work, thereby alleviate The intensity of the later screening work reduces the load on the screen surface and prevents the screen surface from being blocked. At the same time, it enables the grass seeds to be separated quickly and fully in the second stage of threshing work, improving the threshing and separation capabilities of the entire harvester.
