Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a waste straw binding device that is attached to a self-propelled self-elimination device and binds waste straw.

In particular, it is designed to prevent the waste straw that has been scraped in by the police car from returning.

(b) Prior Art Conventionally, applications have been filed for technology that prevents the straw that has been scooped into the straw binding device installed in the self-propelled self-elimination device from returning.

For example, Utility Model Application Publication No. 59-77836, Utility Model Application Publication No. 58
This is similar to the technology described in Japanese Patent No. -113333.

(c) Problems to be solved by the invention In the above-mentioned conventional technology, the backflow prevention member was biased from above the bundling spot. This provided resistance to the rotation of the pin car and needle. Therefore, this resulted in an unnecessary loss of engine horsepower.

The present invention is configured so that the backflow prevention protrusion and backflow prevention rod are urged from below the binding spot, and the urging force of the backflow prevention rod and the backflow prevention protrusion are not applied in the direction of pushing down the packer or needle. That's what I did.

In other conventional technologies, the backflow prevention rod placed from the bundling spot in the rotation locus of the police car was unable to retreat, so the police car was wasting horsepower to push the waste straw bundles into the bundling spot. It was exhausting.

In the present invention, the backflow prevention rod 3 in the part of the pack car trajectory can be stored under the deck while conveying the waste straw, so when the waste straw bundle enters the bundling spot, the backflow prevention rod 3 creates a large resistance. This eliminates the need for The part of the waste straw bundle that is pushed into the bundling spot by the packer and is not subjected to the pressing force by the packer is held by the backflow prevention protrusion 2 that does not retreat, so that the waste straw bundle that is about to retreat is firmly held. be.

(d) Means for solving the problem The purpose of the present invention is as described above, and the configuration for achieving the purpose will be explained.

In the straw binding device attached to the self-propelled self-elimination device, a backflow prevention rod 3 that can be protruded and stored is provided on the deck 8 along the lower surface of the pack car trajectory T, and a binding pocket is provided at the rear of the straw transportation path. Department deck 8
The backflow prevention protrusion 2 is protruded from the backflow prevention protrusion 2.
The protruding position is a position rearward from the terminal end of the pack car trajectory T at an interval of about one bundle of binder bundle diameter, and similarly located in front of the door 1 by one bundle of binder bundle.

(e) Embodiment The purpose and structure of the present invention are as described above, and the operation of the invention will now be explained in conjunction with the structure of the embodiment shown in the attached drawings.

Figure 1 is a side view of a self-propelled self-escape device with the straw binding device of the present invention attached, Figure 2 is a rear view of the straw binding device, Figure 3 is a right side view, and Figure 4 is a rear view of the straw binding device of the present invention. The rear view of the area around the binding pocket, and FIG. 5 are also right side views.

The self-propelled self-escape device will be explained with reference to FIG.

Engine 23 on top of crawler type traveling device 24
A threshing device 20 is arranged, and the grain culm, most of which has been bound with a binder and dried, is provided to the threshing device.

Therefore, the straw binding device of the present invention removes bundles that have been tied together with a binder and become loose due to drying after threshing.
They collect 10 bundles at a time and tie them together again as straw bundles. 22 is a conveyor for frying the grains after sorting.

Moreover, the straw tying device of the present invention has a sliding frame 14.
Slide the top back and forth to adjust the binding position. 2
5 is a sliding adjustment handle for this purpose.

The main parts of the present invention will be explained with reference to FIGS. 2 and 3.

Straw that has been threshed by a feed chain 19 from a threshing device 20 is guided by an intake guide rod 18 and an intake guide plate 6, and enters a bundling pocket from a straw passage. The bundling pocket is supported by a deck 8 at the bottom, closed by a door 1 at the straw discharge side, and held down by a knot frame 5 at the top, and is a space into which the bundler 9 is pushed while rotating from the threshing device side. .

The binder bundle is pushed one after another by the packer 9, and when the inside of the binding pocket is filled with binder bundles, the pressing force of the packer 9 is transmitted to the door 1 through the binder bundle, the door 1 is pushed, and the knot clutch is inserted.

When the knot clutch is engaged, the needle 10 is rotated upward, and the other end of the string is selected in the direction of the knot bill and the string holder, and knotting is performed. Therefore, police car 9
If the binder bundle pushed in returns again, the needle 10 will penetrate the middle of the bundle and knot it, creating a continuous bundle with the next knot.

Therefore, in order to prevent the passing position of the needle 10 from being in the center of the binder bundle, a backflow prevention rod 3 was conventionally provided as a backflow prevention member so as to be able to freely rotate up and down.

That is, since the backflow prevention rod 3 is provided with a coiled spring 3a at its base, it is always urged upward by this coiled spring 3a. As shown in FIG. 2, it is constructed along the lower surface of the rotational trajectory T of the packer 9, and the binder bundle is constructed along this to enter the binding pocket. However, there is only one binder bundle in this backflow prevention rod 3.
This is fine if the binding pocket exceeds the limit, but if the inside of the binding pocket becomes clogged with binder bundles, the elasticity of each bundle will be added, and the bundles pushed in from behind with considerable force will be pushed as the pack car retreats. It is returned and retreats beyond this backflow prevention rod 3.

Therefore, in the present invention, in order to prevent the elastic force of the binder bundle that entered first from being added to the push-back force as much as possible, a backflow prevention protrusion 2 is provided as a backflow prevention member on the door 1 side from the packer trajectory T, and a backflow prevention protrusion 2 is installed on the lower part of the deck 8. It protrudes perpendicularly from the guide plate 4.

The backflow prevention protrusion 2 is formed in a "H" shape, and is structured so that it easily enters in the direction of entry, but is caught in the direction of exit.

Furthermore, the position of the backflow prevention protrusion 2 is at a distance approximately equal to the diameter of the binder bundle from the end of the packer locus T, and similarly, the position of the backflow prevention protrusion 2 is approximately the same as the diameter of the binder bundle from the end of the packer trajectory T. It is located at

By providing a gap equal to the binder bundle diameter in this way, the bundles that have entered together can successfully cross over the dead point of the backflow prevention protrusion and be tightly locked.

13 is a binding string, 11 is a binding mission case,
12 is a power transmission case, 15 is a discharge rod cover, 7
is a release rod, and 21 is a sliding lock lever.

Figure 4 shows the case where there is one backflow prevention protrusion 2.
Of the binder bundles a, b, c, d, and e, a is retained by the protrusion 2, and the return of the binder bundles a, c, and d is restricted.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, conventional backflow prevention members were biased from above the tying spot, so a pressing force was constantly applied from above to the straw at the tying spot, preventing the rotation of the packer and needle. It provided resistance. Therefore, this resulted in an unnecessary loss of engine horsepower.

On the other hand, in the case of the present invention, since the binding spot is biased from below, the biasing force of the backflow prevention rod 3 is applied in the direction of pushing down the packer and needle.
This means that the force exerted by the backflow prevention protrusion 2 is reduced.

Secondly, in other conventional technologies, the backflow prevention rod placed in the rotational trajectory of the packer from the bundling spot could not be moved back, so the packer wasted no time in pushing the waste straw bundles into the bundling spot. It was consuming a lot of horsepower.

In the present invention, the backflow prevention rod 3 placed in the rotation locus of the bundle car 9 from the bundling spot can be stored below the deck 8 while the waste straw is being transported, so that the waste straw bundle can be placed in the bundling spot. The backflow prevention rod 3 no longer poses a large resistance when entering. The part of the straw bundle that is pushed into the bundling spot by the packer 9 and is not subjected to the pressing force by the packer 9 is held by the backflow prevention protrusion 2 that does not retreat, so the bundle of straw that is about to retreat is firmly held. It became possible.
