Description

[Detailed description of the invention] The present invention is a lifting device in which a chain with a stem culm locking claw is wound horizontally on the front side of the lifting device, which is formed by winding a chain with a stem culm locking claw horizontally. A vertically rotating weeding device was installed at the front of the horizontally tilting device to rake up and transfer the fallen stem culms with a locking claw that moves from the lower front to the upper rear in the plane along the direction of movement of the aircraft. Regarding reaping and harvesting machines.

Since this reaping harvester is equipped with a pulling and dividing device, even if the adjacent stem culms that are not to be harvested have collapsed and become intertwined with the stem culms that should be harvested, the culms that should be harvested and the adjacent stem culms can be easily separated. Since adjacent stem culms can be reliably separated while untangling, problems such as stem culm pulling out and shedding, which tend to occur when stem culms are pulled up using only the above-mentioned pulling device, can be significantly reduced. ing.

However, in the conventional pulling weeding device, as shown in FIG. Therefore, the stem culm to be pulled up and divided comes into contact with the mouth edge of the groove, and as the claw 1 moves, the part of the stem culm that is in contact with the mouth edge comes into contact with the side of the claw 1 and the groove. There was a problem in that a large amount of straw waste entered the case 2 because it was caught between the mouth edge of the case 2 and torn off.

The present invention aims to avoid the second problem and perform good reaping work by improving the claws.

Embodiments of the present invention will be described in detail below based on the drawings.

The figure shows a pair of left and right lifting devices 6, 7 for raising the stalk culm to be planted into an upright position, and a stock base of the raised stalk culm at the front of the machine consisting of a crawler traveling device 4 and a threshing device 5. A reaping device 8 that cuts the ends, a device 9 that vertically conveys the cut culms toward the feed chain 5a of the rear threshing device 5, and a puller on the side facing the group of uncut culms when the machine rotates and performs cutting work. Device 6
This figure shows a combine harvester connected to a reaping section including a device 10, which is disposed on the side of the culm, and which pulls up and divides the weeds while touching the entanglement between the culm to be reaped and the culm adjacent thereto.

The pulling devices 6 and 7 have the same structure, and the structure of the left side portion 6 will be explained below. While winding the chain 6b horizontally, the bases of the claws 6a are brought into sliding contact with the upright guide 6C in the upward path from the starting end side, and are restricted to protrude from the case 6d. In addition, other parts are configured to be retired into the case 6d.

The pulling weeding device 10 has a stem culm locking claw 1...
The chain 11, which is pivoted at appropriate intervals, is wound vertically, and the base side of the pawl 1 is brought into sliding contact with the erecting guide 12 in the upward path from the starting end side, thereby regulating the position of protruding from the case 2. However, other parts are configured to be retired into the case 2.

Further, the width of the portion of the locking claw 1 protruding from the case 2 in the pulling and weeding device 10 is set so as to gradually increase toward the claw base side, and at least the width of the portion thereof at its maximum width is larger than the case 2. The width is set larger than the width of the protrusion groove 3 formed in 2.

In carrying out the present invention, as described in the embodiment, if the width of the protruding portion of the locking claw 1 is set to gradually increase toward the base of the claw, the stem culm that is being pulled up can be the nail 1
This is effective in improving the weeding performance by exerting the effect of guiding the grass laterally along the slope of the blade, but the width of the protruding part of the claw should be set larger than the width of the groove in the entire range of the protruding direction. It may be implemented in the form of

Although the embodiments have been described above, the structural features of the present invention can be summarized as follows.

That is, in the reaping/harvesting machine described at the beginning of the detailed description of the invention, the proximal end side of the locking claw 1 portion that protrudes from the case 2 of the weed splitting device 6 is formed in the case 2 to protrude the claw. It is characterized by being larger than the width of the groove 3.

With this configuration, of the mouth edge portion of the nail protrusion groove, the mouth edge portion corresponding to the locking nail is covered by the nail.
The stem culm cannot fit between the claw and the case.

Therefore, there is no possibility of tearing of the stem culm due to its pinching, which has conventionally occurred, and the effect of significantly reducing the amount of straw debris entering the weeding case can be obtained.
