Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a guide body that ensures the straightness of the binder.

(b) Prior art Because binders are generally mown in one direction, counterclockwise, the right wheel or the right half of the wheel on the release side of the bound grain culm is pressed twice, sinking, and tilting to the right, causing the field to deteriorate. Due to the greater running resistance than the surface, the aircraft tries to turn to the right, causing a shift to the right, which greatly impairs maneuverability during straight-ahead work.Especially, the grain culm convergence device is attached to the right tied grain culm release side of the aircraft. This tendency becomes more pronounced in wet rice fields, etc.

(c) Problems to be solved by the invention Although it is normal to equip the binder with an appropriate device to ensure straight movement of the machine, depending on the field conditions or the presence or absence of a convergence device, the machine's Because the degree of rightward deviation was different, it was not possible to maintain the straightness of the aircraft at all times, and it was necessary to remove this device when working in dry fields where there was no such rightward deviation, which was extremely troublesome.

(d) Means for solving the problems Therefore, the present invention solves the above-mentioned drawbacks by installing a guide body that is inexpensive and has a simple structure.

(E) Embodiments Hereinafter, specific embodiments of this invention will be described with reference to the drawings.

Fig. 1 is a plan view of a binder equipped with this invention, and Fig. 2 is a side view of the binder. engine 3 and handle 4
In addition to this, the front of the machine body 1 is equipped with a grass cutting section 5, a conveyance section 6, a binding section 7, etc.

Note that the grass cutting section 5 is provided with a grass separating plate 8, a pulling device 9, etc. from the front, and the conveying section is provided with a conveying plate 10, a conveying belt, etc. Further, the binding section 7 is provided with a binding device consisting of a knot, a billet, etc.

By the way, in this invention, in the weeding part 5 on the uncut grain culm side of the machine body 1, the machine straight guide body 11 has the following shape and extends to the front side.

That is, the front and rear ends of the body straight movement guide body 11 are fitted into the leftmost dividing plate 8 by means of the fixed lower sleeve 12 and the support sleeve 14 fixed to the back surface of the lifting case 13, and are positioned parallel to the body axis. The guide body 11 is held so as to be rotatable and fixed in the left and right directions. That is, when the field is soft and the machine body shifts to the right, the degree of swing of the front end of the guide body in the left-right direction is adjusted depending on the degree of the shift to the right, and an appropriate position is selected. Furthermore, when the field is a dry field, the right side of the machine does not sink and the machine does not shift to the right, so the guide body is oriented parallel to the axis of the machine and acts as a normal weeding body.

Incidentally, it is preferable that the front extension of the body straight guide body 11 be brought as close to the ground as possible.

(F) Effects of the invention When the machine straight guide body 11 with such a configuration is installed and reaping work is carried out in a wet field, the right wheel 2 is stepped twice, and in addition, if the machine is equipped with a convergence device, Because the center of gravity of the aircraft shifts to the right,
The aircraft drifts to the right as it attempts to turn to the right, and unless the steering wheel is constantly pushed to the right to align with the rows of grain culms to be harvested, the front of the aircraft must be corrected to the left. Although it is not possible to maintain the straightness of the aircraft, by adjusting and setting the swing degree of the front end of the guide body 11 in the left-right direction depending on the degree of deviation of the aircraft to the right, the deviation of the aircraft to the right can be prevented. Even when the machine starts, the guide body 11, which extends further forward from the weeding part, catches the leftmost grain culm 15 that is about to be harvested, and prevents the machine from turning to the right, that is, from shifting to the right. It follows the grain culm rows, thereby ensuring the straightness of the aircraft. At this time, since the body straight guide body 11 is installed at a low position, it comes into contact with the stock base of the grain culm 15 and receives a large reaction force from the stock, giving a large correction force, and the guide body 1
Since the guide body 1 extends further forward than the grass dividing plate 8 at the tip of the body, even if the force acting on the guide body 11 is small, it can generate a large moment.

In addition, when working in dry fields where the machine does not shift to the right or rarely shifts, or when a convergence device is not installed, the guide body 11 should be moved further to the left of the row of grain culms that are about to be harvested. It is easy to catch uncut grain culms, which may cause disturbance of the grain culms, so it must be removed.However, this structure can be changed to the normal weeding position and fixed by simply rotating it without removing it. Therefore, its handling properties are significantly improved.
