Description

[Detailed description of the invention] (a) Industrial application field This invention is based on the invention in which the tines that protrude and rise at the lower end of the drawer case, which is installed obliquely with a low front and a high rear, move while drawing an arcuate trajectory in a plan view. This invention relates to a tine hoisting device that starts a latching action on the stock base of a planted grain culm. This is related to the guide rod.

(B) Prior art In the above-mentioned tine hoisting device, the tines are securely attached to the planted grain culm in the vicinity of the turning locus of the tips of the tines that protrude and rotate at the lower end of the hoisting case. In cases where it is difficult to engage the grain culm, especially when the planted grain culm is largely lying down in a direction parallel or substantially parallel to the direction of movement of the aircraft (see Figure 1), it is possible to use tines to hold the fallen grain culm. Unable to scoop it up, it becomes impossible to raise it.

Therefore, in order to prevent the above-mentioned situation, the grass cutting guide, which is fixed to the grass cutting body installed opposite to the pulling case, is extended rearward approximately horizontally while approaching the turning locus of the pulling claw at the bottom of the pulling case. It has been proposed that the rear end be curved toward the upper rear reaping frame part, and that this weeding guide guides the grain culm into the latching area of the tine (for example, Jikkosho (See Publication No. 55-21544).

(c) Problems to be solved by the invention In the conventional technology, although the weeding guide is able to guide grain culms toward the area of action of the tine, the weeding guide is , the tine is extended from a slightly forward part of the tine movement path to the side approaching the rotation trajectory of the tip of the tine and rapidly pushes the stock base of the lodging grain culm to the side, so the sudden and large impact is applied at that time. The drawback was that the grain culms could be pulled out or pushed down even under heavy loads.

Furthermore, in the conventional technology, the lateral overhanging portion of the weeding guide is brought close to the rotational path of the tip of the tine with a gap, and the portion behind this portion is directed in the direction of the reaping frame away from the rotational path of the tine. Therefore, even if the grain culm guided by the lateral overhanging part of the weeding guide was pulled into the tines, the pulling was done at a very shallow position at the tip of the tines. As the tines continue to rotate, the rear part of the weeding guide may curve in the opposite direction, causing the grain culms to separate from the tines, making it difficult to pull them up properly. There was a fatal flaw that could not be avoided.

The present invention was carried out for the purpose of obtaining a guide rod for assisting in lifting which can eliminate the above-mentioned drawbacks of the conventional technology.

(d) Means for Solving the Problems In order to achieve the above object, in the present invention, the tines, which are pivotally attached to a chain that is hung horizontally within the lifting case, are connected to the lower end of the lifting case. In a tine hoisting type hoisting device that protrudes outward at a portion and rotates, a weeding rod is provided extending long forward from a hoisting case opposite to the hoisting case;
When the guide rod is pulled up from the vicinity of the tip of the dividing rod and extended toward the moving range of the tines that stand up and protrude from the lower end of the case, the guide rod is rearwardly extended approximately parallel to the ground when viewed from the side. Extend and pull up the lower end of the case, pass below the tip of the tine that rotates around, pull up to the rear of the case, and bend and extend upward approximately parallel to the case,
Further, when viewed from above, the trailing end portion is formed to extend so as to overlap with the center portion of the tine within the tip rotation locus of the tine.

(e) Operation and Effect of the Device In the lifting device to which the invention is applied, the side view from near the front end of the divider that extends far forward from the lifting case facing the lifting case equipped with tines. The grain culm is guided by a guide rod that is approximately parallel to the ground and overhangs the center of the tine within the rotation locus of the tip of the tine in plan view, so that the grain culm faces the direction of the aircraft's movement. Even under unfavorable conditions where the grain culm is heavily collapsed, the base of the grain culm slides into contact with the guide rod located low and parallel to the ground, and is scooped up without any leakage, gently and effortlessly reaching within the rotational trajectory of the tine. The grain culm is guided to the center of the tine, where the engagement is ensured, rather than the tip of the tine. This eliminates the possibility of the grain culm separating unexpectedly and ensures reliable raising. The grain culm, which is attached to the central part of the rotating tine, is bent and extended upward at the rear of the lifting case, almost parallel to the case, until the tine moves straight. Since this is maintained by the trailing end of the guide rod, the engagement by the tines becomes even more reliable, and the ability to raise the lodging grain culm is significantly improved.

(f) Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

The embodiment shows an example in which the present invention is applied to a binder, and FIG. 3 shows the overall state of the binder in side view, and FIG. 2 shows the state of the reaping binding portion in plan view.

The binder shown in FIGS. 3 and 2 has one or two wheels 2, 2 arranged near the center of gravity of the machine body 1, and an engine 3 and a handle 4 attached to the rear of the machine body 1. The machine body 1 is equipped with a reaping and bundling section including a pretreatment section 5, a conveyance section 6, a bundling section 7, etc. at the front of the machine body 1. The pretreatment section 5 is provided with a grass dividing plate 8, a pulling device 9, a cutting blade 10, etc. from the front, and the conveyance section 6 is provided with a conveyance plate 11, a conveyance belt, etc.

Furthermore, a binding device consisting of a knot, a billet, etc. is installed in the binding section 7.

If the pulling device 9 is used for one-row or two-row cutting,
Corresponding lifting cases 12 and 12' are installed diagonally upward from the rear, and one of these cases 12 is provided with a chain 13 that is horizontally rotated, and the tines 14 are mounted on the chain 13 and protrude upward only on the working side. It is a so-called tine-type lifting device that is installed at appropriate pitches to ensure that

In this lifting device, the tines 14 erect and protrude outside the case at the lower end of the lifting case 12.
The tip rotates while drawing an arcuate locus S in a plan view, and then moves upward in a straight line along the inner edge of the lifting case 12.
The tines 14 begin to engage the planted grain culms in the process of rotating while drawing a circular arc trajectory S. In this case, the planted grain culms within the advancing width of the rotation trajectory S are moved by the aircraft. As it progresses, it enters the rotation trajectory S, so the engaging action of the tines extends,
A lifting case 12' opposite the lifting case 12
It is difficult for the tine to engage the planted grain culms on the side.

Therefore, it is customary to provide a guide rod that guides the grain from the side of the lifting case 12', which is installed opposite to the lifting case 12 equipped with the tines 14, toward the rotation transition area of the tines. In the present invention, the guide rod is installed in a unique configuration as described below.

In other words, the dividing rod 15 is extended forward from the lifting case 12' opposite to the lifting case 12.
, and a guide rod 16 that is raised from the vicinity of the tip of the grass rod 15 and extends toward the rotation movement range of the tines 14 that stand up and protrude from the lower end of the case 12, is approximately parallel to the ground when viewed from the side. The lower end of the case 12 is extended and pulled up, passing under the tip of the tine 14 that rotates around the lower end of the case 12, reaching the rear part of the case, and bending and extending upward substantially parallel to the case, and in plan view, the end of the rear extension. The portion is formed so as to extend so as to overlap the center portion of the tine within the rotation locus S of the tip of the tine.
