Description

[Detailed explanation of the invention] (a) Industrial application field This invention guides a plurality of planted grain culms to the cutting blade part through separate grain culm guiding paths, cuts the culm base, and cuts the grain culm after cutting. The binder has a structure in which the grains are placed against a cross-feeding conveyor plate at the rear of the cutting blade, and transported to the binding part on one side of the cutting blade by a chain with protrusions for binding processing. The present invention relates to an improvement in a raking and conveying device for conveying harvested grain culms toward a bundling section.

(B) Prior art As a conventional example of the above-mentioned binder, there is one that can be seen, for example, in Japanese Utility Model Application Publication No. 52-167125. An elastic guide plate and a guide rod that form a route, a star foil that participates in the grain culm guidance path, and an elastic guide plate that forms a grain culm guidance path on the side farther from the binding part, a guide rod, and a star foil that participates in the guidance path. are installed at the same height, and furthermore, both star foils are arranged at a distance slightly forward from the grain culm engaging area of the chain with projections.

(c) Problems to be solved by the invention By the way, in the grain culm raking and conveying device as described above, the elastic guide plate and guide rod forming the grain culm guiding path on the side close to the bundling part, as well as the star involved in the guiding path. It is necessary to install the foil at approximately the same height as the bundler in the bundling section so as not to disturb the grain culm when it is delivered to the raking action area of the bundler in the bundling section. When the star foils are aligned at the same height, the strong compressive force from the packer will act on the culm at a point that is high away from the culm and is prone to breakage, causing the culm to break and making the culm unaligned. In addition, the position of the needle of the tying part where the string is wound at the point where the pack car passes is naturally high, and the grain culm is tied at a high position and becomes loosely bundled, which is a fatal problem. Because of this problem, the packer must be installed at a low position so that it can act on the area close to the culm of the grain culm, so naturally the star foil, which should be installed at the same height, must also be installed at a low position.

Therefore, the conventional structure in which the star foil, etc. on the side closer to the binding part and the star foil, etc. on the side far from the binding part are installed at the same height is not suitable for the bundle part car that should be installed at a lower position. If the relationship with If the grain culm deviates to the left or right from the narrow part of the guiding path, the elastic guide plate forming the guiding path or the The guide rod comes into contact with the grain culm at a portion close to the culm base and guides it while increasing the degree of collapse, making it easy to disturb its posture, and moreover, the grain culm whose posture tends to be disturbed due to the above. The culm is transferred to the protruding chain by a star foil that is spaced slightly forward from the protruding chain, and the protruding chain also has to be transported over a long distance to the binding point at a distant location. The disturbance in the posture becomes increasingly large due to the contact resistance at the end, and by the time the grain culm from the grain culm guidance path on the side closer to the bundling part merges with the grain and is about to be fed into the bundling part, the conveyance distance is short. Therefore, the grain culms in the grain guidance path on the side closer to the bundling part, where there is less turbulence, and the grain culms that are transported over long distances in a disordered posture intersect with each other, resulting in a state of confusion, resulting in uneven culms. Moreover, the posture of introducing the material into the binding section becomes poor, resulting in a problem of frequent bundling errors.

In addition, in the conventional structure, if the star foil on the side far from the binding part is provided at a height that engages the upper part of the grain culm away from the culm, it is installed at the same height as that. The position of the packer relative to the star foil on the side near the binding part is also high, so the packer applies compressive force to the culm at a position far from the culm base, and the needle wraps the string at a high position. This causes fatal problems such as culm breakage and looseness of the bundle, and in any case, with the conventional structure,
It is not yet possible to prevent irregularities in grain culm posture, uneven culm roots, bundling errors, and loosening of bundles.

Therefore, the present invention transports multiple rows of harvested grain culms toward the binding part, but also rakes and reaps the grain culms on the side away from the binding part in a good posture and transports them in a state with less disturbance. To provide a scraping and conveying device capable of bundling a plurality of grain culms with well-aligned culms and good posture, feeding them into a bundling part and making them into bundles with few bundling mistakes and little looseness.

(d) Means for solving the problem In order to achieve the above object, the raking and conveying device of the present invention has a binding part installed on one side of the horizontally installed cutting blade, and the grain culm is attached behind the cutting blade. equipped with a conveyor plate and a chain with protrusions for conveying the material toward the binding part,
An elastic guide plate and a guide rod are provided at the binding part installation side part, which is the conveyance terminal end side of the chain with projections, and the part on the opposite side to the binding part at the starting end side of the chain with projections, in plan view. Grain culm guiding paths are formed in the shape of a letter and introduce grain culms separately, and the terminals of the conveying paths connected to each guiding path are configured to meet at the connecting part to the bundling part, and the cutting blades in each guiding path are Star foils for scraping and transporting grain culms are arranged at the upper front part of the chain, and the star foil on the side far from the binding part is installed at approximately the same height as the protruding chain. The elastic guide plate and the guide rod that form the guiding path for the star foil are placed at a high position relative to the elastic guide plate and the guiding rod that form the guiding path on the side closer to the binding part. The star foil, elastic guide plate, and part of the guide rod on the side far from this binding part are arranged to wrap around the grain culm engagement area of the chain with protrusions.

(E) Effect Therefore, according to the raking conveyance device of the present invention, the packer of the bundling part and the star foil on the side close to the bundling part are provided at appropriate height positions to carry out trouble-free raking transport of grain culms. On the other hand, the grain culms that are to be scraped and harvested on the side far from the bundling part and transported over long distances are placed high relative to the star foil, etc. on the bundling part side, and are placed so as to wrap around the latching action area of the chain with protrusions. The star foil etc. that are attached to the cutting blade allow for good raking without forcing the cutting blade to fall down, and the wrap structure of the star foil and the chain with protrusions allows the chain with protrusions to be transferred without leakage or stagnation. The grain culms on both guiding routes can be brought together in an orderly manner without intersecting each other, and a group of grain culms with well-aligned culms can be transported. The culm can be introduced into the bundling section with a packer placed at an appropriate height, with little damage, and the culm base can be tightly bound with a needle at an appropriate height.
