Description

[Detailed Description of the Invention] The present invention relates to a bundling device for bundling threshed culms into a certain amount of bundles and discharging them to one side of the combine harvester.

Conventionally, some combine harvesters are equipped with a binding device that binds threshed culms into a certain amount of bundles and releases the bundles to one side of the machine along the traveling direction of the machine.

However, conventional binding devices are composed of a binding mechanism that collects and binds waste culms, and a waste culm bundle carrier that releases the tied waste culm bundles to one side of the machine while changing its attitude. However, the discarded culm bundles transported by the discarded culm bundle transporter are transported by the discarded culm bundle transporter while rotating the plant base using the tip as a rotational fulcrum at the bundling position. In this case, the tip of the bundle of discharged culms being bundled and transported is likely to come into contact with the tip of the trailing discharged culm, causing interference, which may impede the release of the bundle of discharged culms or prevent the bundle from being bundled. There were some inconveniences such as the culms being disorganized and becoming irregular.

The present invention was devised in view of the above-mentioned actual situation, and in particular, the culm guide surface of the binding mechanism has an inclined surface that raises the tips of the culms to be bundled in the direction of collection, and a raised culm guide surface. By forming a stepped guide body having a horizontal surface that supports the tip of the harvested culms, interference due to contact between the bundled and transported bundle of culms and the following culm can be eliminated, and the discharge of the bundle of culms can be avoided. It is an object of the present invention to provide a tying device for a combine harvester that can smoothly perform culms to be tied together, orderly bunch the culms to be tied together, and prevent irregularities from occurring.

The structure of the present invention will be described with reference to an embodiment shown in the drawings. 1 is a threshing section of a combine harvester, 2 is a threshing culm conveying body thereof, and the threshing culm conveying body 2 is
A bundling mechanism 3 is provided at the discharge position of the threshed culms, and a discarded culm bundle conveyor 4 that discharges the threshed culm bundles bound by the bundling mechanism 3 to one side of the machine body is moved from the bundling mechanism 3 to the machine body. It is installed on one side of the car and faces diagonally to the rear. Reference numeral 5 denotes a culm discharge guide surface, and the culm discharge guide surface 5 is provided from below the threshing culm conveyor 2 to the binding position of the binding mechanism 3. In the above-mentioned binding mechanism 3, 6 is a culm scraping body;
7 is a patch, 8 is a needle, and 9 is a door. 1
Reference numeral 0 denotes a sweeper, and the sweeper 10 operates to push the base portion of the discharged culm bundle bound by the binding mechanism 3 and transfer it to the supply port 4a of the discharged culm bundle conveyor 4.

The ejecting culm guide surface 5 of the binding mechanism 3 has an inclined surface 11a that raises the tips of the ejected culms converged on the tip side in the direction of convergence, and a horizontal surface 11b that supports the subsequently raised tips. Step guide 1
1 is formed. In addition, A is a bundled culm bundle, and B is a bundled culm group.

In this invention structured as described above, now,
The waste culms threshed in the threshing section 1 are sequentially conveyed by the waste culm conveyor 2, and are collected on the waste culm guide surface 5 by the waste culm raking body 6 and the packer 7 at the binding position of the binding mechanism 3. . When a certain amount of the culm group B is bundled at the binding position, the needle 8 is operated and the culm group B is bundled.

The discarded culm bundle A bound by the bundling mechanism 3 is pushed by the operation of the sweeper 10 and transferred to the supply port 4a of the discarded culm bundle conveyor 4, and the discarded culm bundle A is transferred to one side of the machine. However, in the process, when the waste culm bundle A is transferred to the supply port 4a of the waste culm bundle conveyor 4 by the sweeper 10, the base of the waste culm bundle A is pushed. , and the supply port 4a of the discharged culm bundle conveyor 4
When receiving the discarded culm bundle A, the discarded culm bundle A is temporarily subjected to resistance opposite to the conveyance direction, so the discarded culm bundle A is rotated using the discarded culm bundle A as a rotational fulcrum with its tip section in the binding position of the binding mechanism 3. The culm bundle A is conveyed while being moved, and the discharged culm bundle A is released to one side of the aircraft along the direction of movement of the aircraft.

By the way, the tip of the ejected culm bundle A that is being conveyed while changing its posture as described above rises in the convergence direction on the ejected culm guide surface 5 along the inclined surface 11a of the step guide 11, and then rises. horizontal plane at position 11
b, and is suspended from the culm guide surface 5. On the other hand, immediately after the start of transport of the culm bundle A, the following culm group B is transferred to the binding position of the binding mechanism 3, but the The tip of the culm group B is the step guide 1.
1, the tips of the culm bundle A and the following culm group B are vertically separated from each other by a step, and the subsequent culm group B is separated from the culm bundle A. It begins to crawl under the . Therefore, the tips of both ears do not come into contact and cause interference, and the ejected culm bundle A is smoothly released, and the subsequent ejected culm group B is not disturbed and becomes irregular. Able to focus and unite in an orderly manner.

In summary, the present invention includes a tying mechanism that collects and binds culms at a discharge position of the threshing culm, and a culm bundle conveyor that discharges the culm bundles bound by the binding mechanism to one side of the machine. The bundling mechanism is provided with a sweeper that pushes the base of the bundled culm bundle and moves it to the supply port of the culm bundle conveyor. Since the stepped guide body has a sloped surface that raises the tips of the bundles of culms to be collected in the convergence direction and a horizontal surface that supports the raised tips, the tips of the bundles of discharged culms that are bundled and transported are Since it rises from the culm guide surface and is supported by the horizontal surface of the step guide, the tip of the culm bundle and the tip of the following culm can be separated by a vertical step, and the tips of both can be separated. Eliminating interference caused by contact between the
This has very useful practical effects, such as being able to orderly bundle the subsequent culms to be bundled and prevent irregularities from occurring.
