Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a knotter for a combine harvester, and more particularly to a knotter in which the roots of the culms are aligned, the tips of the culms are tied together, and the culms are discharged.

[Prior Art] There is a well-known knotter that rakes the threshing culm in a substantially horizontal and horizontally elongated position at the discharge position of the threshing culm of a combine harvester, ties the tip of the threshing culm, and discharges the culm.

In addition, at the bundled culm discharge position of this knotter, the tip side of the bundle of culms is clamped, and the stem side is transported in a hanging position, and the bundle is discharged from the end of the conveyance, so that the bundled culm bundle can be erected on the field. The present applicant has also proposed a device equipped with a bundled culm discharge device.

In this type of knotter, the culms that have been discharged from the threshing device are raked in and the tips of the culms are bundled together before being discharged, which results in uneven culm ends, making it inconvenient to handle the bundles of culms in the future. In addition, in order to accurately stand the shed culm bundles discharged from the bundling waste culm discharge device in the field with the plant side facing down, it is necessary to align the plant bases of the waste culm bundles. This countermeasure was not sufficiently implemented in Nottutar.

[Purpose and structure of the invention] The present invention was developed in view of the above circumstances, and includes a guide body provided above the tip side and the top side of the culms that are tied by knotters. A stock alignment plate is installed to align the stock base of the inserted culm by hitting it from the side of the machine in the direction of the culm, and the height of the guide on the stock base side is set lower than the height of the stock alignment board, By setting it higher than the guide body, the root side, which has a larger volume than the tip side, is compressed from above, and the action of the stock alignment plate is ensured to obtain a bundle of ejected culms with aligned root ends, which facilitates subsequent handling. Make it good and also
To provide a knotter for a combine harvester in which the bundled culm conveyed and discharged by a bundled culm discharge device can be accurately stood on the field with the stock side facing down.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 is a knotter installed at the threshing culm discharge position of a combine harvester (not shown). It is scraped in by the plant head-side packer 3 and the tip-side packer 4 and compressed toward the T-shaped protrusion 5, and when the compression pressure, that is, the amount of ejected culm reaches a certain level, the T-shaped protrusion 5 falls backward. At the same time, a binding mechanism operates to bundle and discharge. Further, a stock head guide body 6 is provided above the stock head side packer 3, a tip side guide body 7 is provided above the tip side packer 4, and the T-shaped protrusion 5, respectively. Further, a stock alignment plate 9 supported by a reciprocating mechanism 8 that reciprocates in the left-right direction with a constant stroke is provided at a lateral position on the stock base side of the threshing culm into which the knotter 1 is raked. Moreover, as is clear from FIGS. 2 and 3, the stock head guide body 6 is higher than the tip side guide body 7,
It is formed lower than the height of the stock alignment board 9.

On the other hand, there is a T at the bundled culm discharge position of knotter 1.
A conveyance chain 10 whose conveyance start end faces a position lower than the platform 2 on the tip side of the culm of the letter-shaped protrusion 5, and whose conveyance end side extends diagonally backward and diagonally upward on one side of the knotter 1; A bundled culm discharge device 13 is supported by the main body of the conveyance chain 10 via two connecting pipes 11, and is comprised of a pinch rail 12 provided facing the conveyance surface of the conveyance chain 10. Then, in the bundled culm discharge device 13,
The tip side of the bundled culm discharged from the knotter 1 is held, the plant side is conveyed in a hanging posture, and it is dropped from the end of the conveyance, and is discharged standing on the field.

In the knotter 1 having such a configuration, the culms threshed by the combine harvester are transferred to the two cutters 3,
4, the platform 2 is successively raked and compressed in a substantially horizontal and horizontal position toward the rear T-shaped protrusion 5. In this raking and compression process, as shown in FIG. The roots of the plants are then hammered in the direction of the culm to align them neatly. When the amount of compression applied to the T-shaped protrusion 5 exceeds a certain level, the T-shaped protrusion 5 falls backward, the tips of the culms are tied together by the binding mechanism, and the culms are discharged by the discharge mechanism. The discharged bundled culm is conveyed by the bundled culm discharging device 13, falls from its terminal end, and is erected in the field with the plant head facing down.

At this time, the bundled culms have their roots arranged in an orderly manner as described above, so when they are released into the field, they are extremely stable and stand up reliably, promoting drying of the field and increasing their roots. Since they are all in one place, the culm bundles can be handled easily.

[Effect of the invention] As explained above, according to the knotter 1 of the combine harvester of the present invention, the stock head side guide body 6 and the head side guide body 7 are placed above the threshing culm that is scraped by the packers 3 and 4. In addition, a stock alignment board 9 is provided for hitting the stock base of the scraped culm from the side of the machine body toward the culm body,
Since the height of the stock-side guide body 6 is set to be lower than the height of the stock alignment board 9 and higher than the height of the head-side guide body 7, the bundling position of the culms is pressed from above before bundling. The culm is guided and compressed in cooperation with the pack car 4, and the stock side of the culm which is raked together with the tip side is compressed in approximately proportion to their respective volumes, and the stock base is struck by the stock alignment plate 9. They are arranged in an orderly manner and the tips are tightly tied together, allowing them to be released. Therefore, since the stems are aligned, the bundled culms can be handled easily, and for example, the tip side of the bundled culms can be held at the discharge position of the knotter, and the culms can be transported with the stem side hanging down. When releasing the plant in a field with the stock side facing down, it can be erected reliably. Furthermore, the binding position is also approximately constant, so that the binding operation can be performed reliably.
