Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION In order to prevent the planted cereal culm from getting caught in the crawler traveling device, the present invention uses a weeding rod acting on the base of the planted cereal culm outside the crawler traveling device. And, more particularly, to a support structure for weeding rods.

[0002]

2. Description of the Related Art It is generally considered that this kind of weeding rod is used by adjusting and fixing an attachment position to an airframe so that planted grain culm can be properly weeded (actually open flat 3).
-114919).

[0003]

With such a fixed weeding rod, when harvesting in a field with relatively hard ground,
Although it acts properly on the root side of the planted grain culm and can maintain a good weeding state, the crawler traveling device may sink unexpectedly in mowing work on a wet field such as wetlands, As a result, the weeding rod strongly presses against the root of the planted grain culm.As a result, the planted grain culm is defeated. There was a risk that the harvesting work would be hindered. An object of the present invention is to realize a reliable mowing operation by properly maintaining the action position of a weeding rod on a planted grain culm when mowing in a soft field, regardless of the sinking of the airframe. .

[0004]

In order to prevent the planted cereal culm from getting caught in the crawler traveling device, a weeding rod acting on the root side of the planted cereal culm is moved along the outer portion of the crawler traveling device. In the combine provided, the weeding rod is suspended and supported on the body so that the weeding rod can be retracted upward in parallel by an external force from below.

[0005]

[Function] In other words, even when the crawler traveling device sinks unexpectedly during mowing work in a soft field such as a wet field, the weeding rod can escape upward, so Without exerting excessive force, it can always act on the appropriate position of the root of the plant and maintain a good weeding state.

[0006]

According to the present invention, it is possible to provide a combine that can properly maintain the weeding state of the planted cereal culm regardless of the sinking of the airframe in a soft field, and can realize a reliable harvesting operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 5 shows a side view of the combine, in which a body 2 having a pair of right and left crawler traveling devices 1 and 1 is provided with a cutting device 3 for cutting planted grain culms, and threshing the cut grain culms from the cutting device 3. And a grain tank 5 for storing grains from the threshing device 4.
As shown in FIG. 4, a pair of left and right crawler traveling devices 1, 1
Of these, the thrust is increased by forming a side propulsion lug on the crawler belt side edge of the right traveling device 1 located below the Glen tank 5, and when the Glen tank 5 is full, the thrust is not affected by the deviation of the machine center of gravity. It is designed to maintain straightness. A front part grass rod 6 extends rearward and upward from the uncut front end of the mowing device 3.
The uncut side planted grain culm is guided to the outside of the machine by the
Is provided to prevent the planted grain culm from being caught in the crawler traveling device 1. This weeding rod 7 is provided along the outer portion of the crawler traveling device 1 and acts on the root side of the planted grain culm to prevent the crawler traveling device 1 from being caught in the traveling device 1.
When a strong external force is applied from below, it is suspended and supported by the body 2 so as to be able to retreat upward in parallel. In other words, as shown in FIG. 1, the weeding rod 7 is suspended and supported via the parallel quadruple link 9 on the maintenance / inspection side deck 8 of the threshing device 4 provided on the body 2. . Then, as shown in FIG. 2, even when the crawler traveling device 1 sinks into the ground during a mowing operation in a wet field such as a wet field, the weeding rod 7 is moved rearward and upward by the swinging of the parallel quadruple link 9. And can maintain a proper weeding state without applying excessive force to the uncut side planted grain culm. In addition, the weeds 7 can be stored upward during a mowing operation in a super wet field or when traveling on a road. That is,
As shown in FIG. 3, the locking holes 10 </ b> A are formed in the side deck 8.
Is fixed, and a locking pin 12 urged toward the plate body 10 by a spring 11 is provided above the quadruple link 9, and the locking pin 12 enters the hole 10A. By swinging the weeding rod 7 rearward and upward to the position, it can be fixed at the storage position. The side deck 8 is supported by the body 2 via a slide structure 13 as shown in FIG.
The lateral extension of the weeding rod 7 relative to the body 2 can be adjusted and fixed. Even if the weeding rod 7 swings rearward and upward, the front end of the weeding rod 7 and the rear end of the front part weeding rod 6 are set so as to overlap in the longitudinal direction of the machine. The side planted cereal stem is not caught on the weeding rod 7.

[Alternative Embodiment] In the above-described embodiment, the weeding rod 7 is suspended and supported on the body 2 via the parallel quadruple link 9 so as to retreat upward in parallel with swinging in the front-rear direction. Although a structure having a structure in which the movement is performed is shown, a structure that allows movement only in the up-down direction using a telescopic support rod, a pantograph, or the like may be used instead. In addition, the weeding rod 7 may be not only downwardly biased by its own weight but also lightly elastically biased.

In the claims of the utility model registration, reference numerals are written for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by the entry.
