Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a reaper that guides the fallen planted stem culm into the area of reaping action and expels it to the outside of the machine. This relates to a device for separating weeds.

(b) Conventional technology In a cutting down type or bundling type reaping machine, a group of planted stems and culms to be introduced into the reaping area of a cutting blade installed horizontally on a grass dividing frame is guided from the front part of the cutting blade. A tine-shaped stem culm lifting device that tilts diagonally rearward and upward is configured to pull up and straighten the plant, but if the degree of lodging of the planted stem culm group is significant, it may be introduced into the area of reaping action. It is not possible to separate the uncut stem culms from the uncut stem culms, and the culms of tangled and fallen stem culms are forced to be separated, so a large load is applied to the stem culms and the culms may be cut or damaged. When the shedding loss increases, problems such as this occur.

For this reason, recently, a lodging culm separating tool is installed on the outside of the side frame body facing the uncut culm of the above-mentioned stem culm pulling device. Efforts have begun to be made to easily separate the tangled culms up to the tip of the culm, and to improve the culm lifting device's ability to assist in raising and straightening the culms and remove uncut culms. However, in most of these types, the dividing tine protrudes upward at the lower end of the casing, which is installed at the outer side of the culm pulling device with an inclination of front and rear height. The system is a type of lodging culm weed separation that moves diagonally backwards and upwards, and the overall structure is complex, large, and heavy. The installation of the separation device significantly disrupts the front-to-back and lateral balance of the aircraft, resulting in poor maneuverability.Since the separation device is large and heavy, it is difficult to support it with sufficient strength, resulting in a lack of durability. I was getting used to it.

Therefore, it has been proposed that the above-mentioned lodging culm weed separator is not of the sorting tine type but of a star foil type in order to simplify the structure and reduce the weight of the weed separator (for example, Jitsukai Showa 55-
(See Publication No. 42933).

(c) Problems to be solved by the invention Although the conventional star foil type weed separator has a simpler structure and is lighter in weight than the sorting tine type, the problems described below still remain. It was on.

In other words, in the conventional system, there is a large distance between the main stem culm pulling device and the grass dividing plate at the front end of the grass dividing frame in the front-rear direction, and a front pulling device consisting of a star foil is placed in the space between the main stem culm pulling device and the grass dividing plate at the front end of the grass dividing frame so that it can be moved vertically. The structure was such that when the pre-pulling device was installed and not needed, the pre-pulling device was pulled up to the inactive position, so when the pre-pulling device was pulled up to the non-activating position, the dividing board and the main stem culm-pulling device were removed. A guiding gap is created between the stems and the stem culm shaping action is not performed well. Since the front hoisting device moves up and down, it is not possible to use multiple star foils, and the action stroke becomes shorter, and the hoisting angle becomes looser than that of the main hoisting device, making it difficult to separate the wheels sufficiently. It won't happen. Moreover, since no measures have been taken to ensure a good succession of stem culms from the dividing board to the star foil and from the star foil to the main stem culm pulling device, the inheritance of the stem culms is poor. The problem was that the posture of the stem and culm was disturbed.

The present invention was implemented with the aim of eliminating the above-mentioned drawbacks of the conventional technology, and the weeding separator is made into a star foil type to simplify and lighten the overall structure, while still having a sufficient action stroke. To provide a weed culling device which can straighten a lodging stem culm and transfer it satisfactorily from a weed dividing plate part to a stem culm pulling device.

(d) Means for solving the problem In order to achieve the above object, the weeding device of the present invention has grass cutting plates 25, 2 at the tip of the grass cutting frame.
The guide frames 1a and 1b of the stem culm pulling device are tilted diagonally rearward and upward from the rear part of 5 to form a stem culm shape guiding path A between them, and the outer side of the guide frame 1a on the uncut stem culm side. A weed separator B formed by multiple star foils 4, 4 is installed in the weed separator B, and the weed separator B separates the stem culms within the guide route A and the uncut stem culms outside the guide route A. In this reaper, the angle of inclination of the action path of the weed separator B is made larger than that of the stem culm pulling device, and the star foil 4 at the lower end of the weed separator is connected to the weed divider plate. The grass divider plate 25 is configured to protrude upward from the cutout groove of 25 and rotate.
Anti-wrapping guide rod 2 extending from both sides of the notch groove
3, 23 and star foils 4, 4, extending rearward and upward along both sides of the wheels.

(e) Effect In the case of a reaper equipped with a weeding device configured as described above, the weeding plate 2 is removed as the machine advances.
5 and 25 advance into the lodging stem culm group and introduce the stem culm group into the guiding route A, and the guiding route A.
Separate into those to be excluded. Thus, the culms of the stem culms inside and outside the guide path A are separated from near the plant base by the star foil 4 at the lower end that projects upward from the cutout groove of the weed dividing plate 25 and rotates, and then continues to be separated from the vicinity of the plant base by the star foil 4 at the upper end. The whole culm is separated into the inside and outside of the guide frame 1a,
The stem culms in the guide route A are pulled up by the stem culm lifting device and are straightened, and the uncut stems outside the guide route A are removed to the outside of the machine by the side divider 24. .

When working with a reaper equipped with the weeding tool B configured as described above, as the reaper advances, the weeding plate 25 advances into the group of planted stems and culms, and the group of stems and culms is moved into the cutting blade. It is divided into 16 things that should be within the reaping area and those that are outside the reaping area (those in the unharvested area). The stem culm within the area of reaping action, that is, on the guide path A, is raked up from the base of the plant by the tines that protrude upward at the lower end of the guide frame 1a and move rearward and upward, and the stem culm is tidyed up from the base of the plant. The stem culm whose plant base is located outside A will be guided by the side divider 24 outside the guide frame 1a and removed to the side of the machine, but when the above-mentioned weeding is performed, the stem culm When the culm group is in a lodging state, especially when the stem culm is leaning on the right side and lodging, the culm bodies of the stem culms that are to be removed laterally by the side divider 24 are difficult to separate. be. However, in the present invention, even after being divided by the weed cutting board 25, the two star foils 4, 4 of the weed cutting tool B are able to catch the uncut side stem culm that is about to fall down to the guide path A side. Since the weeds are separated by rotating from the bottom to the rear and upward, and are completely separated from the stem culms in the guide path A, a good weeding action with extremely low resistance is achieved.

(G) Effects of the invention Since the present invention is constructed as explained above, it produces the effects described below.

The weed separator B that separates the fallen stem culms is formed of star foil, and has a simple and lightweight structure. Constructed in a continuous manner, the inclination angle of the separating action path by the multiple star foils is larger than that of the pulling action path of the stem culm pulling device, and furthermore, the inclination angle of the separating action path by the multiple star foils is formed to be larger than that of the pulling action path of the stem culm pulling device. Since the wrapping prevention rods 23, 23 extending from both sides of the notch groove of the weed dividing plate 25 are installed, the entire culm body of the lodging stem culm whose base part can be divided by the weed dividing plate 25 can be quickly removed. The weeds can be separated from the weeding stage using the weed separator B and handed over to receive the lifting action of the stem culm pulling device, and the posture of the stem culm is not disturbed and there is no omission in taking over, allowing for easy separation. There is a noticeable effect of sorting.
