Description

[Detailed description of the invention] [Industrial field of application] The present invention is designed to provide the following features:
This invention relates to a reaping harvester in which a dividing rod is arranged from the front lower part of the machine body toward the rear diagonally upward so as to separate the stalk culms to be harvested and the stalks not to be harvested.

[Conventional technology]

When separating the stem culms to be harvested and the stem culms not to be harvested, simply placing a fixed dividing rod in an inclined position on the outside side of the uncut side of the pulling device will not produce strong results. It is difficult to sufficiently loosen entangled stems and culms. Therefore, for example,
As shown in Publication No. 5798, it was considered to provide a vertically rotating forced lifting device in place of the fixed dividing rod, but this had the disadvantage of requiring a large-scale device and driving force for forced lifting. be.

For this reason, conventionally, for example,
As shown in Japanese Patent Application No. 52-63650, a straight rod-shaped grass dividing rod having a simple structure is used, and the dividing rod is configured to swing back and forth and in the left and right directions.

[The problem that the idea attempts to solve]

According to the above-mentioned conventional structure, since the weeding rod swings back and forth and left and right, it not only combs the entangled stem culms by swinging back and forth in the direction of movement of the aircraft, but also in the left and right direction. This is useful in loosening entanglements between the stalks and culms, as it also adds a separation effect due to the swinging motion of the culms, but on the other hand, the spikes of the culms are large and swing in a complicated manner, colliding with each other and causing shedding. The problem was that it was easy to occur.

In addition, the amplitude of the straight-rod-shaped weeding rod that swings around the lower fulcrum increases as it reaches the top, so the weeding rod exerts a large straining effect on the intertwined part of the panicle. Grain shedding is also likely to occur at this point, and conversely, if the amplitude is made small so as not to cause large straining, the weeding effect will hardly be exerted on the lower front side of the weeding rod where the amplitude is extremely small, and the weeding effect will be reduced. There was also the problem that the weeding effect was not sufficiently effective because the weeding action was performed only on a part of the terminal side of the weeding rod, and the time required for the weeding action was shortened.

Furthermore, the stem culm, which has finally been disentangled from the neighboring stem culm, separates and moves to the pulling device side or the uncut side, and the panicle part is strained by the above-mentioned weeding rod. It was easy to accept.

By devising the structure of the weeding rod, this invention has a simple structure and allows for effective weeding, but it also prevents the above-mentioned complicated swinging movement of the panicle back and forth and left and right, as well as unnecessarily large swinging movement. The purpose of this is to suppress as much as possible the strong contact with the weeding rod and the weeding rod to reduce shedding.

[Means to solve the problem]

The technical means of the present invention taken to achieve the above object is to move the weeding rod to the horizontally rotating type pulling device on the opposite side of the stem culm introduction path across the pulling device. The weeding rod is located on the lateral outer side of the machine on the non-mow side, and is configured to be swingable around a lower fulcrum and along a vertical plane along the direction of movement of the machine. When viewed from behind beyond the upper end of the lifting device, and
Near the upper position of the pulling device, the rear terminal side of the branch rod is bent so that it is inclined more gently than the front lower side.

[Effect]

(i) The dividing rod is about the lower front fulcrum, and
It swings along a vertical plane along the direction of movement of the aircraft, and provides the entangled stem culm with a swinging motion along the vertical plane. In addition to the oscillation of
Collision between the panicles of the stem and culm caused by the complicated rocking motion of the panicles, such as occurs when the stalks swing in the left-right direction, can be avoided.

(ii) Although the divider rod simply swings in the direction along the vertical plane, the divider rod holds a pulling device with a relatively wide width in between,
Because it is placed on the opposite side of the stem culm introduction route,
It also provides separation action in the left and right directions on the stem culm with less shaking of the panicle, making it easier to loosen with less shedding. In other words, the pulling device itself has a considerable width and is located between the tangled part of the stem culm on the panicle side and the plant base, and the stem culm introduction path is located away from the dividing rod. Therefore, the pulling action of the pulling device equipped with a pulling claw to pull up the stem culm is a force acting on the stem culm in the stem culm introduction path in the direction of separating it from the entangled part with the uncut side of the stem culm. I will be working. Moreover, the acting force has little effect if the entanglement is weak, and only when the degree of entanglement is strong.
Since it acts in the direction of loosening the tangles, it does not pull the stem culm unnecessarily, and there is less risk of unnecessary lateral swaying or frequent strong straining of the panicle.

(iii) Moreover, since the grass divider rod is bent at a gentle slope near the upper position of the pulling device, the front lower part of the grass divider rod is There is little difference in height between the upper limit of the amplitude and the upper rear side. Therefore, compared to the case where the dividing rod is set to the gentle side from the beginning, it is possible to
The weeding effect is given by a relatively large deflection angle,
Also, compared to the case where the slope is steep from the beginning,
It is easy to avoid applying a strong straining action to the tangled part of the panicle near the end of cutting. In other words, effective weeding action using the weeding rod can be repeatedly applied over a relatively long period of time from an early stage after the start of weeding.

(iv) In addition, the terminal end of the weeding rod is gently sloped and extends beyond the upper end of the pulling device when seen from the side, so that the grass tends to separate left and right due to the weeding action. There is also little risk that the panicle of the stem culm will be strongly squeezed by contact with the terminal end of the dividing rod, which is located high relative to the ground, or the upper end of the pulling device. In other words, the stem culm in the planted state is in a fixed position with respect to the ground, and if the dividing rod installed on the movable cutting and harvesting machine is close to a steeply inclined position relative to the ground, the stem culm is easily caught. As can be understood from the fact that if it is close to horizontal, it is less likely to get caught in the stem culm, by making the terminal end of the dividing rod close to the panicle gently sloped, the entanglement of the stem culm can be prevented. It is easy to avoid the situation where the stalk culm, which has been loosened, has its panicle strongly squeezed by the hook of the dividing rod. In addition, if there is a stem culm at the end of the weed rod that has not been loosened and cut even after the lifting action has been completed, loosen it while guiding the upper end of the pulling device until the stem culm passes over. Therefore, it is easy to provide a more reliable loosening action while avoiding contact between the pulling device and the stem and culm.

[Effect of idea]

From the effects of (i) to (iv) above, even though the structure uses a simple weeding rod, there is strong collision between the panicles of the stem and culm, and strong collision with the panicle. It has the effect of providing a sufficient weeding rod in a state where strong straining with the weeding rod is not likely to occur, and allowing good weeding action with less shedding.
