Description

[Detailed Description of the Invention] The present invention relates to a binding device for tied grain culms that can rebind a plurality of tied grain culms to form a large bundle of tied grain culms.

Generally, when threshing with a harvester, etc., a predetermined amount of grain culms is tied together into a bundled grain culm. After threshing, these bundles are combined into a large bundle of grain. Rebinding to the culm is carried out to improve work efficiency such as loading and unloading onto a loading platform during transportation. Conventionally, in a bundling device that rebinds these large bundles into tied grain culms, as shown in FIG.
Since the grain culms B are bundled in a state where they are bundled in a substantially straight line at point a, the re-tied large bundles of bundled grain culms B can be easily removed when being thrown out of the binding device or when being loaded and unloaded onto a loading platform. The tied state shown in Figure 4A, which is approximately linear, collapses into the overlapping state shown in Figure 4B, and the binding string becomes loose, especially when the harvester is equipped with this type of binding device. Since the amount of grain culm on the tip side and stock side of the tied grain culm differs greatly, there was a drawback that the loosened binding string would shift toward the tip side and come off.

The present invention was devised in order to eliminate these drawbacks in view of the above-mentioned actual situation, and when re-binding a plurality of tied grain culms, the present invention is not in a substantially straight shape as in the past, but in a multi-tiered state. It is an object of the present invention to provide a binding device for bundled grain culms that can reliably prevent the binding strings from loosening after rebinding by concentrating the grains and rebinding them.

The structure of the present invention will be explained based on an embodiment shown in the drawings. Reference numeral 1 denotes a binding device, and the binding device 1 includes a mounting base 3 protruding from the grain culm conveying end side of the harvester 2. is installed on. 4 is a traveling device of the harvester 2, 5 is a threshing section, 6 is a feed chain, and 7 is a clamping rail.

The bundling device 1 is composed of a needle 8, a packer 9, a sensing door 10, a sweeper 11, etc. as before, but the guide plate 12 of the bundled grain culm A is provided with In this embodiment, the convergence part 14 located on the locus and facing the nodule part 13 has a step shape that is lower by approximately the diameter of the bundled grain culm A. 15 is a binding string.

Next, the operation of the present invention constructed as described above will be explained. The bundled grain culm A threshed by the harvester 2 is supplied to the starting end side of the guiding plate 12, and is scraped by the packer 9 toward the sensing door 10 side. When the bundled grain culm A is raked in a predetermined amount and collected in the bundler 14, the sensing door 10 senses this, and the needle 8 is linked to the sensing by the sensing door 10 to move the binding string 15 to the bundled part. Quantitative binding grain culm A
After that, a knot is tied to the binding string 15 at the knot 13, and the binding string 15 on the needle 8 side is cut. It will be thrown away.

In performing the above series of binding operations, the harvester 2
is supplied onto the guide plate 12 from the
The bundled grain culm A that is collected into the collection unit 14 by
Since the converging portion 14 has a stepped shape that is lower by approximately the diameter of the bundled grain culm A, the grains are bundled in a densely stacked two-tier upper and lower layer and receive a binding effect, as shown in Fig. 2. . Therefore, even when the re-bound large bundle of tied grain culms B is thrown away from the bundling device 1 or loaded onto and unloaded from the loading platform, the bundling cord 15 does not become loose and the tension does not occur. It will be held in a tied state. Therefore, even if it is provided in the harvester 2 as in this embodiment, the binding cord 15 will not loosen and shift toward the ear tip side where the amount of grain culm is small, and the transportation by a large bundle of tied grain culms B will be prevented. , storage work can be carried out.

In the above embodiment, the converging section 14 is connected to the bundled grain culm A.
Although the steps are lower by approximately the diameter of It is fine as long as it is in shape.

In summary, the present invention provides a binding device for tied grain culms that binds a plurality of tied grain culms collected in a converging part at a knot part, in which the bundling part is arranged opposite to the knot part and the tied grain culms are tied together at a knot part. Since it is composed of a multi-stage convergence section, the bundled grain culms converged in the convergence section are re-bound in the multi-stage convergence state to form a large bunch of bound grain. Because it becomes a culm, this large bundle of tied grain culms does not collapse when being thrown out from the bundling device or when loading and unloading onto a loading platform, and can be maintained in a tautly tied state. It is possible to reliably prevent the binding string from becoming loose after being re-tied.
