Description

[Detailed description of the invention] (a) Industrial application field This invention relates to an improvement of a side divider device installed on the operating section of a combine harvester and on the side where the paddy holder is installed.

(b) Conventional technology In a combine harvester, a paddy holder installed at the rear of the step of the operating section is installed so that it can be rotated and stored, and a cutting rod that can move as the paddy holder is rotated and stored is used for reaping and transport. A side divider device disposed on the lateral side of the machine from the vicinity of the front end of the rice grain holder to the rice holder is already known from Japanese Utility Model Application Publication No. 50-155241.

(c) Problems to be solved by the invention As seen in the above-mentioned publication, the conventional side divider device has a paddy holder connected to the lateral side of the combine harvester body so as to be rotatable in the vertical direction. Under normal circumstances, the platform is maintained in a nearly horizontal position extending outward from the machine body, and when performing hollowing work, it is rotated downward from the above position and retracted into a position approaching the machine body. The weeding rod is provided in a structure in which it is supported and installed in a spanning manner between the vicinity of the front end of the reaping conveyance section and the paddy holder, so that it can follow changes in the position of the paddy holder.

Therefore, regardless of whether the paddy holder is changed to the extended position or the retracted position, the splitting rod remains stretched over the paddy holder part from near the front end of the reaping transport section. The grass cutting rod is always located on the side of the machine from near the front end of the reaping transport section to the paddy holder section, so that it always guides and removes unharvested stems and culms outward. However, when the paddy cradle is retracted during hollowing work, the paddy cradle will be in a drooping position approaching the traveling mechanism of the combine harvester, and the splitting rod will also be lowered accordingly. Particularly in wet fields, mud etc. tend to adhere to the paddy pedestals and grass stalks that are lowered down, and the uncut stems and culms that are guided by sliding on the paddy pedestals and grass stalks become stuck in the grass stalks. There is also the disadvantage that subsequent threshing and straw disposal operations are disadvantageous because the grains are soiled by the mud adhering to the grains, etc., and are also soiled by the mud splashed by the traveling mechanism. Since the paddy pedestal and the dividing rod hang down and are located close to the ground, there is also the problem that when going over the ridge, the paddy pedestal etc. collide with the ridge and are easily damaged.

(d) Means for solving the problems The present invention was implemented in order to solve the above-mentioned problems of the conventional device. In the combine harvester, the combine harvester is configured to be able to be stored by being rotated upward at The body D is connected to a front branching rod D1 which extends from the vicinity of the front end of the reaping conveyance section A and reaches a portion where it overlaps with the step 4, and a front end portion of which wraps around this front branching rod D1 and a rear extending portion which serves as a paddy receiver. It is formed from a rear splitting rod D1 that is supported at a distance from the paddy holder on the lower side of the stand 7, and when the paddy holder 7 is rotated and stored upward, the rear dividing rod D2 is attached to the paddy holder 7. The side divider device moves outward and is positioned in a state where the grass can be separated.

(E) Effect When performing hollowing work (work under the condition that uncut stalks are present on both sides of the combine machine) with a combine harvester to which the device according to the present invention is applied, the paddy holder 7 should be moved upward with the center of the fulcrum shaft 12. The rice holder 7 is brought close to the body B and stored.

In this case, the front branch rod D of the side divider body D
1 extends from the vicinity of the front end of the reaping conveyance section A,
The rear end portion is located below the step 4, and the forward dividing rod D1 independently follows the vertical movement of the reaping and conveying section A without any trouble.

The rear branching rod D2, which is supported and installed on the lower surface of the paddy holder 7, moves outward and upward as the paddy holder 7 rotates upward, and the paddy holder 7 is maintained at a predetermined storage position. Then, the front end of the rear weeding rod D2 wraps around the rear of the forward weeding rod D1 below step 4, and the entire body moves outward and upward of the fuselage B, performing a weeding action. It will be located in the state.

Therefore, when the width of the aircraft is reduced by retracting the paddy holder, the front part of the rear divider will remain wrapped around the front divider, while the overall width will move outward from the paddy holder. The uncut stem culm is positioned so that it can be weeded, and is guided and removed outwardly by the front weeding rod. The machine can easily travel through the area where the culm has been removed, and the hollowing work can be performed without contaminating the uncut stem culm.

(F) Embodiment Next, an embodiment of the present invention will be described with reference to the accompanying drawings, and the overall structure of a combine harvester according to the present invention is shown in FIG. 4.

In FIG. 4, B is the body of a combine harvester, in which a threshing device 3 is mounted on a frame 2 supported by a pair of left and right crawler running mechanisms 1, 1.
A reaping transport section A is installed on the front side of the frame 2 in the direction of movement so as to be able to rise and fall freely, and a driving section consisting of a step 4, a seat 5, an operation column 6, etc. is installed on one lateral side of the reaping transport section A. A paddy holder 7 is provided at the rear of the step 4, and various operating parts such as the threshing device 3, the reaping conveyance section A, and the crawler traveling mechanism 1, 1 can be arbitrarily driven by the engine 8 mounted below the seat 5. It is configured as follows.

Incidentally, with respect to the paddy receiving stand 7, a paddy extracting device 9 for taking out polished grains from the threshing device, a paddy bag racking device 10, and the like are arranged in relation to the paddy holder 7 in the same manner as in a conventional combine harvester.

Therefore, the left side of the machine B is equipped with a left side divider body 11 that guides and removes uncut stem culms laterally outward, and the right side of the machine B, that is, the driving section side, is equipped with a left side divider body 11 that guides and removes uncut stem culms outward. In the present invention, this side divider body D on the driving section side is installed in the following configuration in relation to the paddy holder 7. .

A fulcrum shaft 12 in the front-rear direction installed on the frame 2
The inner end of the inner stand 7a of the paddy receiver stand 7 is mounted on the paddy stand 7 so that it can move up and down, and the inner stand 7a is restricted by a stopper 13, so that the position is the same as the approximately horizontal position (see Fig. 2). It is installed so that it can be rotated upward from the standing position and maintained in the upright retracted position (see Figure 3), and furthermore, the outer end of the inner stand 7a is provided with a mounting shaft 14 that allows the outer stand 7b to be moved up and down. It is constructed so that it can be attached movably and the outer stand 7b can be folded and stored with respect to the inner stand 7a.

In addition, the side divider body D is divided into a front grass dividing rod D1 and a rear grass dividing rod D2. Install it so that it fits under step 4.

The rear branching rod D2 is a support 15, 1 installed on the lower surface side of the inner stand 7a of the rice holder 7.
5, and is installed so that it can move up and down together with the inner stand 7a.
The front part of step 2 enters the lower side of step 4 and is provided so as to wrap around the rear end of the front branch rod D1.

When performing normal work with the combine harvester equipped with the side divider device of the embodiment, the inner stand 7a and the outer stand 7b are maintained extending laterally from the machine body B in a substantially horizontal position as shown in FIG. The mounting area of the entire pedestal 7 is secured widely, the bottom of the paddy bag to be hung is received by the paddy bag racking device 10, and the machine B is moved forward with its left side facing the uncut culm. Let them do the mowing work.

When the machine B moves forward, the unharvested stem culms are removed outwardly by the left side divider 11, the stem culms introduced into the reaping area are cut at the base by the reaping transport section A, and the reaped stem culms are transferred to the threshing device 3. The fine grains are conveyed to the paddy, threshed, and sent out from the paddy removal device 9 of the threshing device 3, and are stored in a paddy bag.
In the case of this circular mowing work, since the driving section side of the machine body B does not face the uncut culms, even if the paddy holder 7 protrudes outward from the machine body B, no problem arises.

When performing hollowing work, there will be uncut stem culms not only on the left side of machine B but also on the right side, that is, on the driving section side, but during this hollowing work,
As shown in Fig. 3, the inner stand 7a is rotated upward around the fulcrum shaft 12 to stand up and retract, and the outer stand 7b is also folded and retracted accordingly. The rear divider rod D2 moves outward and upwardly, and its front end wraps around the rear of the front divider D1 at the point where it enters the underside of the step 4. Therefore, the width of the machine is reduced by retracting the paddy holder 7, and only the rear dividing rod D2 is connected to the front dividing rod D1 below the step 4, and is positioned outwardly and upwardly on the driving section side. As a result, the reduced width body B is located between the uncut stem culms on both sides as shown in Fig. 5.
The uncut stem culms on both sides are removed outwardly by the left side divider body 11 and the right side divider body D, so that the space created by this can be easily traveled, and the hollowing work can be carried out well. It is.

(g) Effects of the invention As explained above, in the invention, the paddy tray 7 installed on the operating section side of the machine B is installed so that it can be rotated upwards and stored, In a combine harvester in which a side divider body D is installed on the lateral side of the machine body from the paddy section to the paddy receiver 7, the side divider body D extends from the vicinity of the front end of the reaping conveyance section A and reaches the lower side of the step 4 of the driving section. It is formed from a front dividing rod D1 and a rear dividing rod D2 whose front end wraps around the front dividing rod D1 and whose rear extending portion extends below or behind the paddy holder 7. , the rear branching rod D2 is supported by the paddy holder 7,
When the paddy holder 7 is stored, the rear weeding rod D2 is moved outward and upward to position it in a position where it can be divided, so the paddy holder 7 can be rotated upward during hollowing work. When it is moved and stored in a position approaching the machine B, the front end of the rear divider D2 wraps around the front divider D1 at the lower part of the step 4, and the entire structure is moved as the paddy holder 7 is retracted. The machine B, especially the crawler, slides into contact with the uncut stem culm guided by the front branching rod D1 at a relatively high position and moves the uncut stem culm outward and upward. It is moved away from the traveling mechanism 1 to prevent mud from getting dirty and to remove it outwards, and the machine body B, which has become narrow due to the storage of the paddy holder, can easily run through the space where the uncut stems and culms have been removed. This has the advantage of allowing for good hollowing work.

In addition, the paddy holder 7 is rotated upward and stored, and as it is stored, the rear dividing rod D2 of the side divider body
Since the grass is designed to rise, when driving over a ridge, simply retracting the paddy holder 7 will raise the ground clearance of the tiller and prevent collisions with the ridge. can be avoided.
