Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary weeding device for a combine harvester.

A combine harvester is provided with a reaping device at the front of the machine, and sends the standing fluff cut by the reaping device to an automatic feeding type threshing device at the rear for threshing.

The reaping device is configured to raise the fallen pile into an upright shape and cut off the root of the pile.

In this case, the unstubble that is present on the side of the moving machine leans toward the machine, which obstructs various operations.

Normally, the unstubbed stubble against the machine body is prevented by installing a guide rod called a narrow guide on the side of the machine body, but the narrow guide alone cannot be expected to have a sufficient effect of preventing the machine body from leaning.

In order to do this effectively, it is best to comb the grass using a mowing lag that rotates in the same way as the cutting blade.

That is, as is well known, the pulling device in a combine harvester is carried out by a pulling device having a lifting lug that rotates in a plane perpendicular to the direction of movement of the machine. It is very effective to install a weeding device with a weeding device in parallel, and use a weeding lag in the weeding device to comb and separate the grass.

In this case, it is preferable that the weeding lug of the weeding device is configured to rotate faster than the pulling lug, and in particular, to operate up to a higher position than the lifting lug.

In other words, when raising the cutting taste, it is enough to raise the root to a state where it is easy to reap, and after that, it is laid down on its side and transported by a conveying device, so there is no need to raise it to an extreme upper position. When pulling up unstubbed trees with a weeding lug, it must be pulled up to a sufficiently high position so that it does not lean against the aircraft.

Therefore, the present invention has been devised so that a lifting device having a lifting lug installed at a front position of the combine harvester has a lifting device at a side position.
A combine harvester comprising: a weeding device having a weeding lug that rotates to weed uncut stumps, the weeding lug of the weeding device protruding to a higher position than the pulling lug and rotating. When viewed from above, the pulling lug and the weeding lug of the rotary weeding device and the combine are perpendicular to the direction of travel, but the weeding lug is diagonally forward. This is a rotary weeding device in a protruding combine harvester.

To explain with a diagram, 1 is a traveling device with a pair of crawlers.
Consisted of.

2 is an automatic feeding type threshing device mounted on the traveling device 1.

A reaping device 3 is provided at a position in front of the traveling device 1.

The reaping device 3 is formed by a weed cover 4, a pulling device 5, a cutting blade device 6, and the like.

Reference numeral 7 designates a conveying device for transporting the stubble harvested by the reaping device 3 to the threshing device 2, and 8 designates a raking device.

The lifting device 5 of the reaping device 3 has a lifting lug 9 that rotates along a plane perpendicular to the machine traveling direction A.

The pulling lug 9 separates the cuttings, and in the present invention, a grass separating device 10 is provided on the side of the lifting device 5.

When viewed from the front side, the weeding device 10 has a structure that is arranged in parallel to the uncut land side P of the pulling device 5.

Reference numerals 11 and 12 indicate a pair of upper and lower sprockets provided on the upper and lower sides of the lifting device 5, 13 indicates a chain wound around the sprockets H1 and 12, and the lifting lug 9 is attached to the chain 13.

There are also a pair of sprockets H4, 15 on the top and bottom inside the weeding device 10.
is mounted on the shaft, and the sprocket [4, 15 is equipped with an endless chino 1]
6 is wound, and the weeding lug 17 is attached to the chino 16.

However, when viewed from the front side, as shown in Figure 1, the uncut land side P
The lifting lug 9 of the pulling device 5 rotates clockwise, whereas the weeding lug 17 of the weeding device 10 rotates counterclockwise.

The raising lug 9 moves upward in a protruding state up to the height shown as h, but the weeding lug 17 protrudes upward to a position considerably higher than the lifting lug 9, as shown as H. The purpose is to sufficiently raise the unstubble.

FIG. 3 is a plan view showing the protruding state of the weeding lug 17. may be tilted diagonally forward and protrude as shown by the temporary line.

Further, the weeding lug 17 generally rotates at a higher speed than the raising lug 9.

Since the present invention has the above-mentioned configuration, when the engine installed at a desired position of the aircraft is started and the aircraft moves forward and each part is rotated, the grass cutting cover 4 divides the stubble and the aircraft moves in the direction of movement. The falling stubble is raised by the lifting lug 9 which rotates along a plane perpendicular to this, the root is cut by the cutting blade device 6, and the stubble is raked by the raking device 8.
The grain is sent to the automatic feeding type threshing device 2 by the conveying device 7 and threshed.

At this time, in the present invention, the weeding device 10 is attached to the side of the pulling device 5, and the weeding lug 1 of the device 10 is attached to the side of the pulling device 5.
7 prevents the unstubble on the uncut land side P from being raked up and leaning toward the aircraft body.

In this case, the weeding lug 17 of the present invention is configured to move upward while protruding to a higher position than the pulling lug 9, so that the unstubble is sufficiently combed up to make the work smooth.

The present invention provides a weeding device 10 having a weeding lug 16 that rotates to weed uncut stumps at a side position of a pulling device 5 having a pulling lug 9 attached to the front position of the combine, The weeding lug 17 of the weeding device 10 is similar to the pulling lug 9.
Since this is a rotary weeding device for a combine harvester that is configured to protrude and rotate to a higher position than the conventional weeding device, it is possible to reliably separate the weeds, unlike a conventional guide rod called a narrow guide. Not only can you do this, but you can also
Since the weeding method 7 is configured to perform the weeding action to a position H that is considerably higher than the raising height h by the conventionally known pulling lug 9, the phenomenon of the unstubble leaning against the aircraft body is almost eliminated. You can prevent this from happening.

In addition, if the protruding direction of the weeding lug 17 is made to protrude diagonally forward when viewed from above, as shown by the phantom lines in FIG. The action becomes faster, and the weeding effect can be improved accordingly.
