Description

[Detailed description of the invention] A conventional combine harvester has a method in which waste straw is fed along a series of guide plates and is scraped into a converging section by a packer. In other words, since the waste straw that is released from the nodules and the following waste straw were on the same plane, when the straw bundle was caught by the blocking rod in order to be released by the sweeper toward the already cut field side, the panicle side was caught by the blocking rod. As the straw turns around the center and thrusts into the following straw and pushes back the panicle side, the posture of the straw is significantly disturbed, and when it is swept into the collecting section by the packer, the culm posture becomes crossed, leading to bundling errors and There were drawbacks such as poor separation of bundles.

The purpose of the present invention is to improve the above-mentioned drawbacks, and includes a pucker for scraping straw into a convergence part in a straw discharge part of a threshing device, and a door for catching the scraped straw. A knotter consisting of a needle that hangs a string on the collected waste straw and supplies the string to the knotting part, and a sweeper that releases the tied bundle of straw is provided, and the released straw is guided to the collecting part. In the case where a guide plate is provided, a guide body protruding from the guide plate toward the convergence part is placed immediately before the convergence part of the knotter and corresponds to the operating locus of the packer on the ear side, and a guide body protrudes from the guide plate from above toward the convergence part. An elastic guide is provided that extends diagonally downward across the rear collecting section, and the ear side of the supplied straw is once received above the collecting section on the upper side of the collecting section by the guide body and the elastic guide. This is characterized by a structure in which the waste straw is raked into the collecting part on the lower side by a packer.

The embodiment shown in the drawings will be explained below.1
is a cutter attached to the rear of the threshing device mounted on the combine machine base, and the waste straw discharged from the culm opening of the threshing device is transported to the top of the cutter 1 by the waste straw conveying device 2. released.

Further, both side plates of the cutter 1 extend rearward to constitute support plates 3, 3, and a support rod 4 is connected to the lower part of these support plates 3, 3. A support rod 6 is connected between the pillars 5, 5 erected on the top of the support rod 3.

7 is a knotter having a knotter 8 and a swivel 9 in the upper part, a door 10, a needle 11, and a puller 12 in the lower part, and a focusing part 13 in the middle part, and has a timing shaft driven by a one-turn clutch inside. The cylinder 14 is supported by a support arm 15 on the lower support rod 4 so as to be adjustable in lateral movement.
From the ear side end of the cylinder 14 to the transmission case 15a
(In Figure 1, the middle part is removed) Stand up,
A holding cylinder 16 of the knot shaft, which extends from the upper part to above the needle 11 and the like and has the knot part 8 attached thereto, is connected to the upper support rod 6 via a support arm 17 so as to be adjustable in lateral movement.

Also, from the rear upper surface of the cutter 1, the focusing portion 1 is
A guide plate 18 for guiding the discharged straw is provided at a portion extending through the lower part of the door 3 and near the base of the door 10.

Further, an intermediate portion of an arm 21 is fixed to a rotating shaft 20 supported by frame plates 19, 19 projecting forward from both ends of the support rod 6, and is loosely fitted onto the rotating shaft 20 to form a continuous rod 21'. A cam plate 23 protruding downward is fixed to the cylinder body 22 which is integrally supported by the support rod 6 through the arm 21, and the tines 24 rotatably supported at both ends of the arm 21 are connected to the cylinder body 22 by a winding spring. A roller 25 that is pressed toward the cam plate 23 and is pivotally supported in the middle is in sliding contact with the circumferential surface of the cam plate 23.

The guide plate 26 is located at a portion where the rear part of the raking locus a of the tines 24 and the front part of the raking locus b of the packer 12 overlap when viewed from the side on the ear side of the knot 8 of the guide plate 18. The base is fixed, and the guide plate 26 extends rearward while being raised, and its tip reaches just in front of the convergence part 13.

Further, the elastic guide 27 whose base is fixed to the upper support rod 6 descends obliquely to the rear, wraps with the tip of the guide plate 26, and then extends further to the side of the door 10.

When the waste straw discharged from the waste straw conveying device is to be shredded, the switching plate 28 is opened, and the waste straw is shredded by the cutter 1 and scattered on the field.

Furthermore, when the switching plate 28 is closed when bundling waste straw, the discharged waste straw passes over the switching plate 28 and slides down onto the guide plate 18, and the tine 24 rotates while being regulated by the cam plate 23. , 24 is the focusing section 13
Scrape in until just before the
However, the ear side rides on the guide plate 26 constituting the guide body, and the picker 12 scrapes the scraped straw into the collecting part 13 against the elastic rod 27, and the ear side rides on the guide plate 26 constituting the guide body. It passes over the plate 26 and passes into the focusing section.

When the door 10 senses that a predetermined amount of waste straw has been focused on the focusing section 13 by repeating this scraping action, the clutch engages once, and the needle 11 is hooked back to the focusing culm and returns to the knotted section. When the straw bundles 8 are activated and knotted, the sweeper 9 discharges the straw bundles to the rear.

At that time, the tip side of the straw bundle is the cylinder 14 and the holding cylinder 1.
Since the straw bundle is received by the ear removal rod 29 and the elastic guide 27, which are connected to each other, the straw bundle turns around the ear removal rod 29, and the tip of the straw turns backward.
By simply entering the space c formed below the trailing straw that is lifted and supported by the guide plate 26, the ears of the trailing straw will not be pushed back forward, and the elastic guide 27 will move the straw bundles to be released. The upper surface of the ear side is pressed and released in an orderly manner.

In Figure 1, d represents the stock capital, and e represents the stock capital.
shows the side part of the panicle held down by the elastic guide 27.

As mentioned above, the present invention includes a straw discharging part of a threshing device, a packer that scrapes the straw into the collecting part, a door that receives the scraped straw, a string that hangs on the bundled straw, and a string. A knotter consisting of a needle that supplies the straw to the knotting part and a sweeper that releases the tied bundles of straw, and a guide plate that guides the released straw to the collecting part,
Immediately before the converging section of the knotter and corresponding to the operating locus of the packer on the ear side, there is a guide body that protrudes from the guide plate toward the converging section, and a guide body extending diagonally from above to the converging section behind the guide body. The ear side of the supplied straw is once received by the guide body and the elastic guide above the upper side of the convergence part, and the received straw is sent to the lower side by the packer. Since the straw is raked into the collecting part by the packer, when the straw is raked into the collecting part, the ear part side, which was received by the guide body and the elastic guide, moves beyond the guide body and into the collecting part. When the sweeper releases the bundled straw bundles in this state, the straw bundles rotate around the panicle side, and the panicle part returns to the rear in the raking direction and rotates.
The ears of the subsequent straw ride on the guide body, and the ears that have rotated back enter the space below the guide body so that they do not intersect with the ears of the succeeding straw and are pushed back. It is possible to prevent bundling errors or bundle separation from worsening due to disturbed posture of the straw.
