Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a stubble pulling device on the side of a combine harvester.

(Prior Art) At the front of a conventional combine harvester, a raising case having a lug for raising the standing stock to be harvested is arranged in parallel. That is, the standing stock to be harvested that has fallen down or is tangled is raised by the lifting lug, and in the raised state, the root is cut and threshed.

In this case, there are standing unshorn stubbles that will be harvested next on the side of the combine machine, and as these unstubbles lean against the combine harvester and interfere with the work, use guide rods etc. to the sides to prevent them from leaning against the combine machine. Move forward while pressing in the opposite direction. The guide rod is usually called a narrow guide.

(Problem that the invention aims to solve) However, since the narrow guide simply pushes the standing unshorn plants in a direction farther from the aircraft body and pushes them out to the side, it cannot be expected to have a sufficient effect. There is even a flaw in which the erect, uncut plants are pushed forward as the aircraft moves forward.

Therefore, in the present invention, a pulling lug is used to pull up the unstubble in place of the narrow guide, and the mechanism for transmitting the rotational power at that time is specially devised.

(Means for Solving the Problem) Therefore, the present invention provides a plurality of grass cutting covers 4 in parallel at the front position of the combine harvester body, and a plurality of vertical grain culm pulling cases 5 at the rear of the grass cutting covers 4. A sprocket 9 and a sprocket 10 are installed in parallel to each other, and a sprocket 9 is fixed to the upper part of the grain culm lifting case 5, and a sprocket 10 is fixed to the lower part of the grain culm lifting case 5, respectively, and the sprocket 9 and the sprocket 10 have a raising lug 12 for raising the standing stock to be reaped. In this case, the shaft 13 of the lower sprocket 10 of the grain culm lifting case 5 located closest to the uncut land P among the grain culm lifting cases 5 is A protrusion 15 is formed by protruding rearward from the back side a, a gear 16 is fixed to the protrusion 15, a reversing gear 18 is meshed with the gear 16, and an unstubble pulling case is attached to the shaft 19 of the reversing gear 18. A sprocket 20 provided at the lower part of the combine harvester 14 is fixed, a sprocket 23 is fixed to the upper part of the unstubble raising case 14, and the unstubbed standing stock on the side of the combine harvester body is raised by the sprocket 20 and the sprocket 23. The above-mentioned defects have been overcome by a configuration of an unstubble pulling device on the side of the combine harvester in which a chain 24 having a lifting lug 25 is wound around.

One embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a traveling device which is composed of a pair of crawlers, and an automatic feeding type threshing device 2 is mounted on the upper part of the crawler.
3 is a supply chain of the threshing device 2, and in FIG. 1, the side where the supply chain 3 is provided is the uncut land side P. In front of the traveling device 1, a reaping device 7 including a weed cover 4, a stubble culm lifting case 5, a cutting blade device 6, etc. is provided. 8 is a conveying device. The weed cover 4 is located at the leading edge of the machine body, and the grain culm raising case 5 is provided behind it.

A pair of sprockets 9 and 10 are mounted on the top and bottom of the grain culm lifting case 5, and an endless chain 11 is wound around the sprockets 9 and 10. 12
is a lifting lug, which is attached to the endless chain 11. Reference numeral 13 is a rotating shaft of the sprocket 10 at the lower part of the grain culm lifting case 5, and the axial direction of the shaft 13 is approximately parallel to the direction in which the machine moves. A plurality of grain culm lifting cases 5 are installed vertically, and an unstubble lifting case 14 is provided on the back side of the grain culm lifting case 5 located closest to the uncut land side P.

That is, as shown in FIG.
The rear side of the shaft 13 of the lower sprocket 10 of the grain culm lifting case 5 located at
is fixed and surrounded by a conductive case 17. (However, the conduction case 17 can also be used as the grain culm lifting case 5.) Inside the conduction case 17,
A reversing gear 18 that meshes with the gear 16 is built-in. When viewed from the side, the reversing gear 18 is located higher than the lower sprocket 10, as shown in FIG. A rotating shaft 19 of the reversing gear 18 projects rearward from the transmission case 17, and a sprocket 20 at the bottom of the lifting case 14 is fixed to its projecting end.
The connecting portion between the lifting case 14 and the conduction case 17 is such that the shaft tube 21 is rotatably fitted into a bearing 22 protruding from the lifting case 14, so that the lifting case 14 can be rotated about the rotating shaft 19. Configure it to do so. The lifting case 14 has upper and lower sprockets 23, 20, and the sprockets 23, 2
Hang the endless chain 24 between 0 and the endless chain 24.
A lifting lug 25 is provided.

(effect) Next, we will discuss the effect.

Since the present invention has the above-mentioned configuration, when the traveling device 1 is rotated and the machine moves forward, the harvested standing plants are separated from side to side by the weeding cover 4, and the separated standing plants are placed in the grain culm lifting case 5. It is pulled up by the lifting lug 12, and in that state is harvested by the cutting blade device 6, and is supplied to the threshing device 2 by the conveying device 8, where it is threshed.

In this case, on the side of the moving machine, on the uncut land side P, there are standing uncut bushes that are not cut, and this leans against the machine body and obstructs the reaping operation, but the present invention
An unstubble lifting case 14 is provided on the back side of the grain culm lifting case 5 located closest to the uncut land side P among the grain culm lifting cases 5 installed in parallel, and the unstubble lifting case 14 has a lifting lug. 25, the lifting lug 2
5 to push it away from the aircraft.

That is, the reversing gear 18 is rotated by the gear 16 fixed to the rear protrusion 15 of the lower shaft 13 of the grain culm lifting case 5, and the shaft 19 of the reversing gear 18 is rotated, so that the lifting lug 25 is attached. Rotate the endless chain 24 to raise the erect and unshorn stubble,
Push it away from the aircraft.

However, when power is transmitted from the shaft 13 at the bottom of the grain culm pulling case 5 as described above, the shaft 13 rotates clockwise when viewed from the front, whereas the shaft 19 at the bottom of the stubble pulling case 14 rotates clockwise. Although it rotates to the left, it is rotated from the sprocket 10 at the bottom of the grain culm lifting case 5 via the reversing gear 18, so when the lifting lug 12 of the grain culm lifting case 5 rotates to the right to raise the reaped grain culm. The lifting lug 25 of the unstubble lifting case 14 rotates counterclockwise to pull up the unstubble on the side of the machine body.

(Effects) As mentioned above, on the sides of the conventional combine harvester, there is standing unshorn stubble that will be harvested next. The guide rod is usually called a narrow guide, but since the narrow guide simply pushes it sideways by pushing it, it moves forward with a guide rod or the like. Not only can you expect effects, but
There was even a flaw in which the unstubble was pushed forward as the aircraft moved forward.

Therefore, the present invention has been devised to pull up unstubble with a pulling lug instead of the narrow guide, and has specially devised the rotational power transmission mechanism at that time. A plurality of grass cutting covers 4 are arranged in parallel at the front position of the machine, a plurality of vertical grain culm lifting cases 5 are arranged in parallel at the rear of the grass cutting cover 4, and a sprocket 9 is installed in the upper part of the grain culm drawing cases 5. A sprocket 10 is fixed to the lower part of the grain culm lifting case 5, and the sprocket 9 and the sprocket 10 are provided with a lifting lug 1 for raising the standing stock to be harvested.
2, the shaft 13 of the lower sprocket 10 of the grain culm lifting case 5 located closest to the uncut land P among the grain culm lifting cases 5 is connected to the grain culm lifting case 5. A protrusion 15 is formed by protruding rearward from the back side a of the protrusion 15.
A gear 16 is fixed to the gear 16, and a reverse gear 18 is attached to the gear 16.
The sprocket 20 provided at the lower part of the unstubble lifting case 14 is fixed to the shaft 19 of the reversing gear 18, and the sprocket 23 is fixed to the upper part of the unstubble lifting case 14, and the sprocket 20 and The structure of the unstubble pulling device on the side of the fuselage of a combine is constructed such that a chain 24 having a lifting lug 25 for pulling up uncut standing stubble on the side of the fuselage of the combine is wound around the sprocket 23. It can be expected to have a much better effect in preventing buckling than the pressing effect of the narrow guide on unstubbed stubble. Moreover, since the rotational power transmission mechanism of the lifting lug 25 is configured as described above, the sprocket 10 at the lower part of the grain culm lifting case 5
Not only can more power be obtained and it can be formed easily and at a low cost, but when power is obtained from the lower sprocket 10 as described above, the rotation of the pulling lug 25 is reversed, but since the reversing gear 18 is interposed there. ,
The lifting lug 25 can be easily rotated in the desired direction. In addition, when the reversing gear 18 is interposed, the lower sprocket 10 of the grain culm lifting case 5
Lower sprocket 2 of unstubble lifting case 14
0 will result in a higher position, but the unstubble lifting lug 25 does not need to be rotated lower than the reaped grain culm lifting lug 12; in fact, better results will be obtained if it is rotated at a higher position. This also has a very advantageous effect.
