Description

[Detailed description of the invention] [Field of industrial application] The present invention involves harvesting crops such as rice using a reaping mechanism, and then tying the harvested grain culms to an appropriate thickness using a tying mechanism, and then tying them laterally. The present invention relates to a device for smoothly guiding the stock base of the harvested grain culm toward the binding mechanism in a reaping and binding machine (binder) that is configured to release the grain.

[Problems that conventional technology and ideas try to solve]

In general, this reaping and tying machine is configured so that the grain culm harvested by the reaping mechanism is scraped into the tying mechanism by a star wheel or the like that comes into contact with the middle part of the grain culm. There is a problem in that the transfer of the stock base in the grain culm to the bundling mechanism is delayed.

Therefore, Japanese Utility Model Publication No. 48-24603 as a prior art proposes a guide spring rod with a fixed tip and a free rear end between the weeding body and the reaping mechanism in the front part of the reaping and tying machine. The structure is arranged in an inclined manner so as to extend diagonally inward from the cutting body toward the rear, and the stem part of the harvested grain culm is guided in the direction of the binding mechanism by the elasticity of the guide spring rod. It is proposed to reduce the delay in transferring the stock part by configuring the system to do so.

However, if the guide spring rod is still provided between the grass cutting body and the reaping mechanism at the front part of the reaping and tying machine as in this prior art, when the reaping and tying machine moves forward, The base of the uncut grain culm to be planted comes into contact with the base end of the guide spring rod, and the guide spring rod remains largely displaced outward. The action of repelling and guiding the reaped grain culm in the direction of the binding mechanism by the rod is inhibited, in other words, the action of repelling and guiding the reaped grain culm in the direction of the binding mechanism by the guide spring rod is inhibited. There was a problem in that the stock base of the uncut grain culm planted in the field came into contact with the base end of the guide spring rod, resulting in a significant reduction in mortality.

The object of the present invention is to provide a guidance device that overcomes the problems of the prior art.

[Means to solve the problem]

In order to achieve this objective, the present invention provides a pair of left and right grass dividers in the front part of a transmission case equipped with running wheels, and a reaping mechanism is respectively disposed in a part between the grass dividers and the transmission case. On the other hand, in a reaping and tying machine comprising a tying mechanism disposed behind one of the weed cutting bodies and at a side portion of the reaping mechanism, the cutting and tying machine is arranged such that the other of the two weed cutting bodies and the A guide spring rod, whose front end is fixed to the frame rod that supports the other grass cutting body and whose rear end is free, is installed between the mowing mechanism and the mowing mechanism in an obliquely inward direction toward the rear in a plan view. The frame rod is disposed in an inclined manner so as to extend to the top of the mechanism, and on the inside of the frame rod supporting the other grass division, there is an inward slope extending diagonally inward from the frame rod rearward in a plan view. and a parallel portion extending from the rear end of the inwardly inclined portion toward the rear in a state substantially parallel to the traveling direction of the reaping and binding machine to a portion intersecting the guide spring rod, when viewed from the side. The structure is such that it is provided at a location approximately at the same height as the reaping mechanism.

[Functions and effects of the idea]

In this configuration, when the reaping and tying machine moves forward, the grain culms to be planted in the field are separated by a pair of right and left tillers, and the grain culms that are between the left and right tillers, and the uncut grains outside of both the tillers. The grain culms that have been divided into grain culms and have entered between the two division bodies are harvested at the base of the stock by the reaping mechanism, and then tied to an appropriate thickness by the binding mechanism, and then tied to the appropriate thickness by the reaping and tying machine. Released laterally.

Then, the stock base of some of the grain culms that have entered between the two plants comes into contact with the guide spring rod, which causes the guide spring rod to move outward against its elasticity. The moment the grain culm is flexibly deformed and reaped by the reaping mechanism, it returns to its original position due to elastic force, and the stem end of the reaped grain culm is flipped and guided in the direction of the binding mechanism.

However, in this case, when the grain culm before reaping comes into contact with the proximal end of the guide spring rod, the guide spring rod is largely bent and deformed in the outward direction, and becomes separated from the binding mechanism. Therefore, the effect of guiding the repelling of grain culms by the guiding spring rod is reduced.

On the other hand, the present invention includes an inwardly inclined part that extends diagonally inward from the frame rod in a plan view on the inside of the frame rod that supports the other of the weeding rods; A guide rod having a parallel portion extending rearward from the rear end of the inwardly sloping portion in a state substantially parallel to the traveling direction of the reaping and tying machine is provided at a location approximately at the same height as the reaping mechanism when viewed from the side. With this guide rod, the base of the grain culm before reaping can be guided inward,
In other words, the guide spring rod can be forcibly guided in a direction away from the proximal end, and as a result, the guide spring rod can be prevented from being significantly bent and deformed in the direction away from the binding mechanism. Therefore, it is possible to reliably prevent the effect of guiding the grain culm from being reduced by the guiding spring rod.

Moreover, the guide spring rod is located above the reaping mechanism, and the guide rod is located at a site approximately at the same height as the reaping mechanism, while the guide spring rod and the guide rod intersect in plan view. With this structure, when the grain culm is transferred from the guide rod to the guide spring rod, there is no chance of the grain culm falling out or being pinched.

As described above, according to the present invention, when guiding the harvested grain culm to the bundling mechanism, the delay in guiding the grain culm at the stock base can be avoided without causing the grain culm to drop or the grain culm to be pinched. , has the effect of reliably preventing.
