Description

[Detailed Description of the Invention] The present invention relates to a rice grass harvesting machine that is equipped with a reaping device and a device that changes the harvested rice grass into a horizontal position and supplies it to a sorting device.

In such a rice grass harvester, the grass to be harvested is cut and fed to the sorting room in a state where it is intertwined with the uncut rice grass located on the side thereof, so that the harvested rice grass is pulled by the uncut rice grass that is entangled with it. Due to tension, the feeding posture of the cut straw grass to the sorting room may be disturbed,
Many inconveniences occurred, such as breakage of cut and uncut grass.

Therefore, conventionally, as seen in the technique disclosed in Japanese Utility Model Application Publication No. 56-57033, a weeding swinging rod that swings from side to side with its front end as a fulcrum is installed on one side of the grass introduction path in front of the reaping device. It was designed to separate the tangles of grass to be harvested and grass that was not to be harvested, but since the structure is such that the separation is done by swinging a single swinging rod from side to side, the next step is to It had the following drawbacks.

That is, in order to untangle long grass grass with a single rod-shaped weeding swinging rod, it is necessary to greatly change the amplitude of the weeding swinging rod. However, increasing the amplitude of the weeding swinging rod increases the swinging speed of the weeding swinging rod, which has the disadvantage that the impact force on the grass is strong and the grass is damaged. Therefore, in order to solve this problem, by slowing down the swinging speed of the splitting swinging rod, the constant number of strikes per unit time will be reduced, and the separation effect caused by the vibration of the shot will be reduced, resulting in a good impact. There was a problem that the separation effect could not be achieved.

Furthermore, the conventional structure had the problem that the separation effect was poor because only the separation effect was caused by impact.

The present invention has a weeding structure that separates the grasses to be cut and the grasses that are not cut by applying a striking action to the grasses that are not cut.
The purpose is to make improvements to suppress damage to grass rush and improve separation effect.

The characteristic structure of this invention to achieve the above purpose is as follows:
Two grass cutting swinging rods are arranged in a V-shape in plan view on one side of the grass introduction path in front of the reaping device, with an attitude tilted upward from the ground, and the two grass cutting swinging rods are arranged in a V-shape in plan view. The rod is configured to be swingable via a drive mechanism capable of driving and swinging in the same direction with the front end portion as a fulcrum, and further, the two weeding swinging rods are configured to be swingable via a spacing adjustment and changing mechanism. The structure is such that the relative spacing can be changed, and this structure provides the following effects.

That is, since two weeding swing rods are provided and arranged in a V-shape in plan view, the V-shaped structure exerts a weeding action on the grass to be reaped and the grass that is not to be reaped. Separation efficiency is improved by separation by grass action and impact action. Since the two weeding swing rods are configured in a V-shape, by adjusting the relative spacing between them, the weeding action range of the V-shape can be enlarged. It is possible to expand the range of weeding action as a whole without increasing the amplitude of the swinging rod, and the swinging speed of the weeding swinging rod is slower than when using a single rod-shaped swinging rod. do,
It was possible to ensure a constant number of blows per unit time, and it was possible to suppress damage to the rush while also achieving a good separation effect by the blows.

Hereinafter, an embodiment of the present invention will be described based on the drawings. A clipper-type reaping device 1 that cuts the base of planted rush grass, and a clipper-type reaping device 1 that clips the cut grass with the base side ahead of the tip side. By conveying the grass rearwardly and upwardly by a pair of conveyor belts 2A and 2A, and by conveying the succeeding ears upwards by a locking conveyor belt 2B..., the cut grass is changed to a sideways posture with the ear side facing forward, and the sorting device 3 The rice straw harvesting machine has a device 2 for supplying the feeder, the sorting device 3 and the control device 4 to a body frame 6 equipped with a pair of left and right running wheels 5, 5. It is provided with a pair of holding and conveying belts 3A, 3A which pinch and convey the rush in the lateral direction, and a pick-up belt 3B which removes the conveyed rush that is less than a set length.

On one side of the rush introduction path A to the reaping device 1, there is provided a section that is tilted upward from the ground and can be driven and oscillated in the same direction with approximately the same amplitude from side to side with its front end as a fulcrum. Move the grass swinging rod 7 up and down 2
tiers and arranged in a V-shape in plan view, and furthermore, the swing center of the lower weeding swinging rod 7 is displaced toward the introduction path A side from the swinging center of the upper weeding swinging rod 7. At the same time, a fixed weeding tool 8 is provided in front of these swinging rods 7, 7.

The driving mechanism K of the two weeding swinging rods 7, 7 is provided with a shaft 9 that swings in conjunction with the front pulley 2a of the outer clamping conveyance belt 2A in the feeding device 2 via a crank mechanism B. It is constructed by attaching arms 11, 11 to the swing shaft 9, which are pivotally connected to the respective grass swinging rods 7, 7 via pins 10, 10.

Further, the relative spacing between the two weeding swinging rods 7, 7 can be changed via a spacing adjustment/changing mechanism M.

The change in the relative spacing between the two swinging rods 7, 7 is as follows:
This is accomplished by changing the position of the arms 11, 11 in which they are attached to the swing shaft 9 around the swing shaft axis, thereby changing the positions of their swing centers to the left and right. The mounting posture of both arms 11, 11 can be changed through elongated holes 16, 16 for inserting mounting bolts 15, 15 formed in each arm 11, 11.

The front end portions of the grass swinging rods 7, 7 are supported so as to be swingable left and right and to be movable in their longitudinal direction via a pair of upper and lower pincushion members 12, 12, respectively. .

In the figure, reference numeral 13 is a swinging rod attached to the swinging shaft 9, which separates the cut grass in the transport direction, and 14 is a collecting section for the sorted grass.
