Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a reaping and tying machine for single-row reaping, which guides the base of the planted stem culm toward the cutting blade and reaps it. This invention relates to a reaping and conveying device that feeds stem culms into a binding pocket of a binding machine.

(b) Prior art In a single-row type reaping and binding machine, the binding machine is installed with the entrance of the binding pocket connected to one side of the cutting blade installed horizontally on the reaping frame, and A star foil is provided on the front side of the blade, and a star foil guide guides the stem culm to the raking action part of the star foil. A stem culm guide path is formed by a plant guide spring that is located in the scraping action part of the star foil and is brought into contact with the star foil guide, and the stem culms are moved along this stem culm guide path and converged in the bundling pocket. Conventional examples of this type of reaping and conveying device include, for example, the Jikkosho
Those shown in Japanese Utility Model Application Publication No. 58-36250 and Japanese Utility Model Application Publication No. 58-70735 are known.

(c) Problems to be solved by the invention The former mentioned in the prior art is the upper one of the two strain guiding springs that are arranged vertically across the star foil and extend to the conveyance path. The lower one is made shorter than the lower one and positioned within the rotating trajectory of the star foil, and the lower one is positioned near the rotating outer periphery of the star foil to avoid misalignment with grain culms planted on the side far from the star foil. The method is to guide the grain culms without bending them excessively by making the grain diameter small, and although the stock guiding spring extends to the conveyance path, the free end of the strain guiding spring is located at the center of the widthwise direction of the conveyance path. Since the grain culm was simply placed in a floating state approximately parallel to the conveyance path, the spring force needed to be strong enough to hold the force necessary to press the grain culm toward the star foil. Can not.

As a result, the base of the grain culm is subjected to an unnecessary strong spring force when it is sent into the conveyance passage and subjected to the compression action of the packing car, which increases the degree of damage. It is impossible to prevent the culm from swelling and rebounding during the return stroke of the packer, and the backflow due to the strong spring force and repeated recompression by the packer will cause further damage to the grain culm. There was a problem with the stock price becoming uneven.

In this regard, in the latter technique described in the prior art, the stock guiding spring that presses and guides the stock base of the stem culm toward the star foil is shortened so that its end is located at the stem culm sending part of the star foil. The stem culm retaining tool is energized to return to a position that receives and prevents the backflow of the stem culm stock base from the binding pocket, and is brought into contact with the terminal end of this stock guiding spring. Therefore, it is possible to stop the backflow of the stem culm, but this requires not only a stock guiding spring but also a return energized stem culm holder, which complicates the structure and increases cost and handling. There were some disadvantageous issues.

The present invention was made by focusing on the above-mentioned problems in the conventional technology, and its purpose is to eliminate the need for a stem culm holder to prevent backflow of the stem culm, and to use only a stock guiding spring. While accurately performing the function of guiding the stem culm to the scraping action part of the star foil, it also reliably prevents the back flow of the stem culm from the binding pocket, resulting in less damage to the culm as a whole. To obtain a reaping conveyance device capable of performing good reaping conveyance without unevenness of the base of the stock and disturbance of posture.

(d) Means for solving the problem, that is, the reaping conveyance device of the reaping and tying machine according to the present invention is such that the inlet of the tying pocket 8 is connected to one lateral side of the cutting blade 7 installed horizontally on the reaping frame 4. A star foil guide 19 is provided with a tying machine 9, a star foil 18 is provided in the front part of the entrance part, and guides the stem culm to the scraping action part of the star foil 18;
A plant guide spring 20 whose front end is attached to the reaping frame 4 on the opposite side of the tying machine 9 and extends backward to come into contact with the star foil guide 19 at the scraping action part of the star foil 18 is used to secure the stem culm. In the reaping conveyance device of the reaping and tying machine in which the guide path 21 is formed, the free part of the stock guiding spring from the contact part with the star foil guide 19 to the tip is fed along the tip rotation locus 14 of the pruning car 15 of the above-mentioned tying machine. The binding pocket 8 is extended diagonally across the process side and further beyond the return process side, and its free end is connected to the binding pocket 8.
It is characterized in that it is brought into sliding contact with the rear wall 11a of the.

(E) Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

In addition, the reaping bundling part B has a stem culm pulling device 6 installed diagonally rearward and upwardly from the rear of the weeding body 5 provided at the front end of the reaping frame 4, and the reaping frame 4 below the end of the pulling path. The cutting blade 7 is horizontally installed in the cutting blade 7, and a bundling pocket 8 is provided on one side of the cutting blade 7.
A deck is provided in which a binding device 9 is installed by communicating the entrance part of the stem, and the stem culm is placed in a position from one side of the pulling path to the rear side of the binding pocket 8, and the stem culm is bent slightly backward. 10 is installed.

The binding machine 9 is provided with a knotting section consisting of a knotting cover 12, a bill holder, etc. on the front side of the binding pocket 8 formed in the middle part of the binding mission case 11 in the front and rear direction. On the rear side, a needle 16, a stem culm receiving door 17 which also serves as a binding clutch actuating body, a packer 15 which operates in a substantially elliptical rotation locus 14, and the like are arranged.

A star wheel 18 that is forcibly rotated is provided at the front part of the entrance of the binding pocket 8, that is, from the front to the upper part of the cutting blade.
is installed, and a star foil guide 19 for guiding the planted stem culm toward the scraping action portion of the star foil 18 is attached.

The star wheel guide 19 is formed by bending an appropriate rigid material such as a rod, and its front end is attached to the binding transmission case 11, and the part extending from the attachment part is at the center of the cutting blade in plan view. After being curved and protruded toward the tubercle cover 12, the extending end portion is formed so as to be located along the tip of the tubercle cover 12. A culm guideway 21 is formed.

The plant guide spring 20 is installed by attaching its front end to the reaping frame 4 located on the opposite side of the tying machine 9, and the part extending rearward from the attachment part is attached to the scraping action part of the star foil. The star foil guide 19 is extended so as to be in contact with the star foil guide 19, and the free portion beyond the abutting portion is inserted into the binding pocket 8 by extending it along the feeding stroke of the tip rotation locus 14 of the pack car 15 and beyond the return stroke. is extended diagonally across the binding pocket 8, and the extending end is attached to the rear wall 1 of the binding pocket 8.
It is provided in sliding contact with 1a.
