Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a stem culm pulling device such as a binder or a combine harvester.

(b) Conventional technology In conventional stem culm pulling devices, in order to improve the separation of raised stem culms and uncut stem culms when reaping fallen stem culms, a pulling case is used in which the tines protrude and move backward and upward from below. A weed cutting case is provided on the side of the uncut stem culm of the plant so that the tines stand up forward and move upward. (For example, see Utility Model Application Publication No. 56-1442 or No. 54-23825.) (c) Problems to be solved by the invention A weeding case is installed parallel to the uncut stem culm side of the conventional raising case. In this case, since the stem culm is a soft culm that has fallen down, there was a problem in that the raised end of the stem culm raised by the weeding case gets entangled with the tines and is brought into the weeding case and wrapped around it. (Japanese Utility Model Publication No. 56-1442) Therefore, it has been proposed to provide a guide which gradually kills the action of the tines from the front of the end of action of the tines of the weeding case to the end of action. (Utility Model Application Publication No. 54-23825) Although the installation of the above-mentioned guide solved the problem of the stem culm getting entangled with the tines and being brought into the weeding case, the problem was solved because the pulling stem culm was soft. ,
The tip of the pulling stem culm remains at the top of the weeding case, causing disturbance to the stem culm located at the end of the pulling path, preventing smooth transfer of the stem culm to the next process, and causing the stem culm to remain in the transfer area. There were still problems that had caused the blockage.

In the present invention, the stem culm is not entangled with the tines and brought into the weeding case, and the tip of the pulling stem culm is guided from the upper part of the weeding case to the end of the outside part of the pulling path, It is an object of the present invention to provide a stem culm lifting device that prevents the stem culm located at the terminal end from being disturbed and allows the stem culm to be smoothly transferred to the next process.

(d) Means for solving the problem In order to achieve the above object, in the pulling device of the present invention, the tines 1 project along the uncut stem culm side of the lifting case 4 that moves from the bottom to the rear and upward. Then, a weed cutting case 5 is provided in which the tines 2 stand up forward and move upward, and the starting end of the guide guide 7 is positioned inside the upper part of the middle part of the weed cutting case 5. 7 is gradually raised from its starting end to a curved position higher than the standing height of the tines 2, and its rear is gradually directed from the starting end to the terminal end of the outer side of the pulling path 3. be.

(e) Action In the lifting device configured as above,
The fallen stem culm is first scooped up by the tine 2 of the weeding case, and immediately after that, the tine 1 of the lifting case 4 acts on the scooped up stem culm by the tine 2 to pull it up. 1 and 2 jointly raise the reaped stem culm and separate the raised stem culm from the uncut stem culm. , the guide 7 gradually separates the grass from the tines 2 and prevents it from being brought into the grass cutting case 5 and becoming entangled;
The raised end of the stem culm that is away from Tine 2 is
The guide 7 guides the stem to the terminal end of the outer side of the lifting case 4, and corrects the stem culm posture to a smooth transition to the next process.

(F) Example An example will be described with reference to the drawings. In Figures 1 and 2, A is a combine harvester, and a stem culm pulling device B is installed at the front of the combine A. and the pulling device B includes a lifting case 4 in which the tines 1 protrude into the pulling path 3 and move from below to the rear and upwards, and a lifting case 4 along the side of the lifting case 4, on the uncut stem culm side by the combine harvester A. The tines 2 stand up in the front and consist of a weeding case 5 that moves from the bottom to the rear and top.

Further, as shown in FIG. 3, the lifting ends of the lifting stems 6 are connected from the inner surface of the upper middle part of the weeding case 5 to the lifting passages 3, which are the protruding ends of the tines 1 of the pulling case 4. Towards the outer end, guide guide 7
When viewed from the side in FIG. 1, the guide 7 projects upwardly and rearward from the side of the weeding case 5, and gradually increases below the height of the tines 2 at the upper end of the weeding case 5. It is curved in a high protruding manner and extends to a position above the raising case 4 and the weeding case 5.

In the plan view of FIG. 2, the guide 7 extends from the weeding case 5 to the end of the outer side of the pulling path 3 of the stem culms 6... It is formed to extend along the sea urchin.

Tines 1... and 2... of the pulling case 4 and the weeding case 5 protrude from the front part of the fuselage 9 of the combine A through the power transmission means in the power transmission case 11 at approximately the same speed, rise, and move back. is configured to enter.

In addition, 12 is a reaping device, and 13 is a weeding body.

When the combine A, which is a reaping and harvesting machine, moves through the standing stem culms 6..., the roots of the stem culms 6... are pulled up by the cutting body 13 of the pulling device B, and the pulling stems enter the pulling path 3. It is separated into the culm side and the side that will become the uncut stem culm, and then the tine 2 of the weeding case 5...
stands up and scoops up the pulled stem culm and the uncut stem culm,
Toward the tip of the stem culm 6..., the grass is separated while being pulled up following the cutting body 13, and then the tines 1... of the lifting case 4 protrude into the pulling path 3,
The stem culm 6... is raised.

At the final stage of this state, the pulling end of the stem culm 6 is entangled with both the tine 1 of the pulling case 4 and the tine 2 of the weeding case 5. Lifting route 3 from the middle top
The stem culms 6 are guided to the pulling path 3 side while being removed from the tines 2 of the weeding case 5 by the guides 7 projecting out to the side, and at the end of the pulling path 3, the tines 1 of the pulling case 4 are removed. When the lifting is completed and a good reaping posture is achieved, the reaping device 12
The harvested grains are harvested, guided to the next stage of conveyance route 8, and threshed inside the fuselage of combine A.

(g) Effects of the invention Since the present invention is configured as explained above, it produces the effects described below.

1. Since the weeding action of the tines 2 of the weed splitting case 5 is gradually killed by the guide 7 at the terminal end, the stem culm is untangled from the tines 2 by the guide 7, and the stem culm 6... This prevents the grass from being brought into the weeding case 7 and getting caught up in it.

2 The pulling end portion of the pulling stem culm is lifted upward by the guide 7 and transferred to the end on the lifting path 3 side, and the upper and side parts are connected to the pulling end portion of the pulling stem culm and the uncut stem culm. Since the separation force in both directions acts at the same time, the separation is performed in such a way as to loosen the two, preventing the culm from breaking at the entangled portion or lifting the culm, and also separating the two quickly and quickly.

3 The pulled end portion of the pulled stem culm is separated from the uncut stem culm by the guide guide 7, and at the same time is guided to the outer end of the pulled path 3 by the guide guide 7, so that the culm assumes the posture immediately after being pulled. There is no disturbance, and the handover and processing to the next process is performed smoothly.

4. The guide 7 has the function of eliminating the entanglement of the stem culm with the tine 2, the function of separating the entanglement between the pulled stem culm and the uncut stem culm, and the function of preventing the pulled stem culm from being disturbed, so the number of parts can be reduced. The structure is simple.
