Description

Technical Field

[0001] The utility model relates to the field of debris removal devices, in particular to a debris removal device and a harvester with a debris removal roller capable of conveniently adjusting the height thereof. Background Art

[0002] As a major food crop, corn is widely planted in various regions of my country, with a total planting area of ​​about 35 million hectares nationwide. Corn harvesters are popular among people. The debris removal device of corn harvesters is responsible for separating corn cobs from corn stalks and discharging the stalks. When harvesting corn of different maturity, the operator's habit is usually: when harvesting green corn with low maturity, the harvesting speed is often slow (similarly, the transmission speed of corn cobs in the harvester is also slow), the corn cobs generally do not touch the debris removal roller, and the stalks can be grabbed by the debris removal roller and run out of the vehicle; when harvesting corn with high maturity, due to time constraints (the end of the harvesting season or before the snow falls), the operator's harvesting speed is usually very fast (the transmission speed of corn cobs in the harvester is also fast), the traditional debris removal roller cannot adjust the height, and the corn cobs transmitted at high speed have a higher parabola. The cobs are extremely easy to touch the debris removal roller, resulting in grain damage and incomplete cobs, poor harvesting effect, and the cobs are prone to mold.

[0003] The existing solutions are: either harvesting at a low speed to affect efficiency, or removing the trash rollers to prevent collisions. However, removing the trash rollers requires removing at least four bearings and using a special tool such as a puller, which is time-consuming and labor-intensive. In addition, this method also makes it difficult to remove the straw, leaving a large amount of straw in the ear box, which also results in poor harvesting results. Utility Model Content

[0005] The technical solution of the utility model to solve the above technical problems is as follows: a debris removal device with conveniently adjustable height of debris removal rollers, comprising a debris removal shell, two middle plates and a debris removal roller assembly, wherein the debris removal roller assembly is located in the debris removal shell, and its two ends are respectively connected to the two middle plates, and the two middle plates are respectively detachably connected to the two opposite side walls of the debris removal shell.

[0006] The beneficial effect of the utility model is that the debris removal roller assembly is made into an integrated movable type. During high-speed harvesting, the debris removal roller assembly can be moved up a certain distance by only separating the two middle plates from the debris removal shell body. No special tools are needed to remove the bearings, so that the debris removal roller assembly can avoid the landing point of corn ears, reduce collisions, and obtain a good harvesting effect.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, two opposite side walls of the impurity removal shell have adjustment holes, the two intermediate plates are located outside the impurity removal shell, and the two ends of the impurity removal roller assembly pass through the two adjustment holes respectively and are detachably connected to the corresponding intermediate plates.

[0009] The beneficial effect of adopting the above further solution is that when the position of the debris removal roller assembly needs to be adjusted, the middle plate is moved, and the debris removal roller assembly can move within the range of the adjustment through hole to avoid interference with the debris removal shell.

[0010] Furthermore, the adjusting through hole comprises a main body hole and an extension hole, and the extension hole is in a strip shape, and one end of the extension hole is connected to the main body hole.

[0011] The beneficial effect of adopting the above further solution is that the extension hole can avoid the movement of the debris removal roller assembly, and at the same time, it is avoided that the hollow area of ​​the adjustment through hole is too large to affect the strength of the debris removal shell.

[0012] Furthermore, the debris removal roller assembly includes an active roller and a passive roller, the active roller and the passive roller are parallel to each other, two ends of the active roller are respectively connected to the two middle plates, and two ends of the passive roller are respectively connected to the two middle plates.

[0013] The beneficial effect of adopting the above further scheme is: external power is input to the active roller, the active roller rotates and drives the passive roller to rotate through the transmission component; or, when the active roller rotates, the straw is brought between the active roller and the passive roller, and the passive roller rotates passively.

[0014] Furthermore, the adjustment through hole includes four extension holes, and the four extension holes are arranged opposite to each other in pairs relative to the main body hole.

[0015] The beneficial effect of adopting the above further solution is that the four extension holes are arranged in groups of two, and the two groups of extension holes are respectively used to avoid the movement of the active roller and the passive roller.

[0016] Furthermore, both ends of the active roller and both ends of the passive roller are rotatably mounted on the corresponding intermediate plates through bearings.

[0017] Furthermore, a handle is fixed on each of the middle panels.

[0018] The beneficial effect of adopting the above further solution is that when adjusting the middle plate, the movement of the middle plate is operated by the handle, which is convenient to operate.

[0019] Furthermore, the handle is in a strip shape and is arranged along the upper edge of the middle plate.

[0020] The beneficial effects of adopting the above further solution are: the handle has a simple structure, light weight and low manufacturing cost.

[0021] Furthermore, the side wall of the impurity removal shell is provided with a plurality of groups of installation holes arranged at intervals, and the intermediate plate is detachably connected to one group of the installation hole groups.

[0022] The beneficial effect of adopting the above further solution is that the intermediate plate and the debris removal roller assembly can be adjusted to a plurality of different positions as required.

[0023] The utility model also provides a harvester, comprising the debris removal device capable of conveniently adjusting the height of the debris removal roller.
