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

Embodiment 1

[0031] see details Figure 1 to Figure 5 , a fully fed rapeseed combine harvester, comprising a body 1, a grain storage tank 30, a power system, a header 2 hooked to the front end of the body 1 and a walking device 3 arranged below the body 1, and it also includes a The threshing device 4 in the upper part of the machine body 1 and the residue treatment device 5 at the front of the machine body 1, the lower part of the threshing device 4 is provided with a screening device 31, and the top of the header 2 is provided with a reel device 32 (ie, reel), The header 2 is arranged at the front end of the body 1 and includes a set of double-action transverse cutters 6 and vertical cutters 7 on both sides; wherein, the double-action transverse cutters 6 are located below the front end of the header 2 for cutting Compared with the horizontal cutting knife in the prior art, the rape stalk not only enhances the shearing effect of the rape stalk, but also can adapt to the thick rape stalk....

Embodiment 2

[0035] see detailsfigure 1 and Figure 4 , as an improvement of the above-mentioned first embodiment, the residue treatment device 5 includes a lifting device connected with the header 2 and a support arm 8 driven by the lifting device and moving synchronously with it. The residue treatment device 5 is mainly used for The straw stubble left after the rape stalk is cut at the shearing and cutting table 2, wherein the support arms 8 are located on both sides of the body 1, the front end of the support arm 8 is provided with a cutter 9, and the rear end is connected to the body through the main support shaft 18. 1 connection; the lifting device includes three lugs 10, two connecting rods 11 with long holes 14, a pull rod 12 and a steel rope 13, wherein the three lugs 10 are respectively connected to the header 2, the body 1 On the knife holder 55 of the cutter 9, one end of the two connecting rods 11 are respectively connected with the lugs 10 on the knife holder 55, the two long...

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 body 1, wherein the primary threshing roller 19 includes a threshing roller shaft 21, a connecting ring 22 and a threshing hub 23. The skeleton, and the corrugated rod 24 connected to the skeleton, the first-stage threshing roller 19 of the corrugated rod structure can strengthen the rapeseed threshing effect of the first stage, and reduce the crushing strength of the rape straw in the first-stage threshing work, thereby reducing the The strength of the screening work in the later stage can reduce the load of the screen surface, avoid the blockage of the screen surface, and at the same time make the grass seeds more quickly and fully separated in the second-stage threshing work, and improve the threshing and separation capacity of the entire harvester.

[0040] The secondary threshing roller 20 is arranged...

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, in particular to a rapeseed combine harvester. Background technique [0002] Because the rapeseed plants are tall, have many branches, and have long podding sections, the ratio of grass to seeds is high, the load of threshing and separation is large, and the moisture content of the straw is high, which is not conducive to the separation of grass and seeds, and the harvesting loss rate is high. Most growers More willing to carry out manual harvesting, resulting in a low degree of mechanization of rapeseed harvesting in my country. [0003] The rapeseed combine harvester currently used is usually: a full-feed rice-wheat combine harvester is transformed, that is, by lengthening the header, and setting vertical cutting knives and horizontal cutting knives perpendicular to each other in front of the body, among which the horizontal cutting The knife is located at the front and bottom of the machi...
