Description

[Detailed explanation of the invention] When feeding grain culms to a tying machine and converging them, by extending the root leveling plate from the scraping part to the concentrating part, the roots of the grain culms being bundled are not disturbed and are well aligned. It can be tied up in a ivy state.

However, when releasing the straw bundles, the terminal end of the straightening plate acts as a resistance to the straw bundles released by the sweeper, resulting in disadvantages such as the direction of the straw being thrown out of order and the throwing distance being shortened.

The present invention aims to provide a root alignment device for a tying machine that can perform good root alignment and does not cause release resistance. The plate is configured to be freely reciprocally driven in the direction of the culm, and the root leveling plate and the sweeper of the bundling device are interlocked so that at least a portion of the root leveling plate facing the converging portion moves backward when releasing the bundle. That is.

The embodiment shown in the drawings will be explained below.1
is a threshing device mounted on the base of a combine harvester, and a cutter 3 for shredding the straw transported by a straw transporter 2 is attached to the rear of the threshing device. The binding machine 4 has a knotter 5 and a sweeper 6 at the upper part, and a bundler 7, a needle 8, and a door 9 at the lower part across from the converging part 5a.

Also, a hexagonal shaft 11 that drives the scraper 10 and a support frame 12 to which the upper part of the binding machine 4 is attached so as to be movable laterally.
The stock side of the cutter 3 is supported by a front-opening U-shaped rod U installed at the rear of the left side plate of the cutter 3, and the ear side is supported by a support plate installed upright on the right side plate.
The arm 13 rotates together with the hexagonal shaft 11, and the cam 1 is pivotally supported at the tip of the arm 13 and is supported by a spring.
4 and tine 15 which are pressed into contact with each other.

Reference numeral 16 denotes a rotating body that is fitted onto the hexagonal shaft 11 and has an eccentric ring 16a at one end, and the rear part of the frame member 17 whose front portion is loosely fitted to the other end is attached to the support frame 12 by a pusher 18 and a set bolt 19. It is installed so that it can be moved and fixed.

A root leveling plate 21 is fixed to the lower part of the vertical shaft 20 rotatably supported at the rear of the pedestal 17, extending from the side of the scraping body 10, through the side of the focusing part 5a, and just in front of the door 9. An arm 22 fixed to the upper part of the vertical shaft 20 connects to the rod 2 via a ball joint 23.
4, the rod 24 is fitted into the eccentric wheel 16a through a bearing, and is connected to the mounting portion of the wheel body 25 through a spring 26 and a nut 27, and the rod 24 is connected to the eccentric wheel 16a through a bearing. The portion and the rear portion of the longitudinal axis 20 are bent outward.

Next, to explain the transmission mechanism, the threshing device 1
When the cutter shaft 28 is driven by an appropriate shaft,
The input shaft 29 of the bundling machine 4 rotates, and the hexagonal shaft 11 rotates accordingly, so the scraping body 10 performs scraping operation along the locus shown in FIG.
The rotation of the 6a causes it to swing left and right around the vertical axis 20, and the front part of the vertical axis 20 hits the root ends of the scraped straw to align them, and the rear part hits the root ends of the gathered straw to align them. Arrange.

In addition, the gear 3 attached to the input shaft 29 of the binding machine 4
0 meshes with the gear 32 of the packer shaft 31, and the gear 3
3 meshes with a gear 35 that is loosely fitted on the needle shaft 34, and the gear 35 and the needle shaft 34 are interlocked and connected via a one-turn clutch 36.

Furthermore, the input shaft 29 drives the hexagonal shaft 11 via sprockets 37, 38 and chain 39, and the joint shaft 40 drives sprockets 41, 42 and chain 43.
It is driven by the needle shaft 34 via the needle shaft 34.

Thus, sprockets 37 and 38 and gear 30
and 32 are 2:3, respectively, so the hexagonal shaft 11, nodule shaft 40, needle shaft 34, and packer shaft 31 rotate at a rotation ratio of 1:1:1:1, and the nodule shaft 40 rotates at a rotation ratio of 1:1:1:1. The sweeper 6 and the root leveling plate 21, which are operated by rotation, are connected so that the rear part of the root leveling plate 21 is separated from the root end of the straw when the sweeper 6 operates to release the bundle.

In the above-mentioned apparatus, the waste straw carried out by the waste straw conveyor 2 is scraped by the scraper 10 toward the bundling machine 4, and then passed to the bundler 7 and collected in the bundling part 5a.
and is focused on the front of the door 9.

In such a raking process, the part in front of the vertical axis 20 of the root leveling plate 21 aligns the roots of the straw scraped by the raking body 10, and the part behind the vertical axis 20 aligns the roots of the collected straw. Beat it to align it and prevent it from getting messy.

When the door 9 senses that the amount of condensation has reached a predetermined amount, the one-turn clutch 36 is engaged and the needle 8 is activated to wind the string around the condensed straw, and the knotting section 5 is also activated to perform the knotting operation, and the sweeper 6 releases straw bundles.

At that time, the sweeper 6 starts from point a and moves from point b to
It operates on the path c-d-a, and in conjunction with this, the rear part of the root leveling plate 21 swings in the path A-B-C-D-A. That is, a-
In the b-c process, the root leveling plate 21 advances to the collecting part 5a to align the roots of the straw, and in the c-d process, the sweeper 6 enters the collecting part and discharges the straw.
Since the root leveling plate 21 is retracted from the position to the D position, it does not become an obstacle to the bundle discharge.

Furthermore, since a combine harvester generally adjusts the handling depth of the harvested grain culm before supplying it to the threshing device 1, the root position of the straw will vary if the culm length differs. In this case, loosen the set bolts 19, move the rotating body 16 along the hexagonal shaft 11, move the rear part of the frame 17 along the support frame 12, and tighten the set bolts 19 to remove the position of the root leveling plate 21. It can be adapted to the root position of the straw.

Furthermore, by adjusting the rotation of the nut 27, the amount of compression of the spring 26 and the direction of the leveling plate 21 can be adjusted.

In the drawing, reference numeral 44 denotes a stalk blower, and when the sweeper 6 discharges the stock side of the straw bundle, it receives the stalk side, so that the straw bundle is discharged while turning.

As mentioned above, the present invention has a root leveling plate on the stock side of the bundling device that extends from the scraping part to the concentrating part and can be driven reciprocally in the direction of the culm, and the root leveling plate and the sweeper of the bundling device are connected when releasing the bundle. Since at least the part of the root leveling board facing the collecting part is interlocked to move backward, it is possible to not only level the roots in the process of raking the waste straw into the collecting part of the tying machine, but also to remove the collected waste straw. Although it can prevent the roots from being disturbed, the root leveling plate moves backward when releasing the straw bundles, so it does not impede the movement of the straw bundles and keeps the straw bundles at a predetermined position far back. can be released.
