Description

[Detailed Description of the Invention] (a) Field of Industrial Use The present invention relates to a cord for a combine knotter that binds straw that is harvested and threshed by a combine and discharged.

(B) Conventional technology Conventionally, when bundling straw is bound by a bundling machine attached to a large, high-efficiency combine, if the string balls are small (the string length is short), the number of string ball replacements increases and work efficiency increases. I used a string of large balls because it would drop.

(C) Problems to be solved by the invention With respect to the known large ball string described above, when the string on the center side is pulled out, the string ball collapses or the string becomes entangled, which makes it difficult to pull out the string.
There were problems such as string breaks.

(D) Means for Solving the Problems In the present invention, a cylindrical body having a plurality of slits having a string-drawing-side opening is fitted on the outer periphery of the inner layer of the string ball, and the inner layer is continuously formed on the outer periphery of the cylindrical body. By winding the string as an outer layer and pulling out the string from the center side of the string ball, when pulling out the string of the inner layer of the string ball and then pulling out the string of the outer layer, the string of the outer layer is held by the tubular body. So, I solved the above problems,
While pulling out the cord of the outer layer, the pull-out side of the tubular body was reduced by the slit to have a small diameter to facilitate the pulling of the cord of the outer layer.

(E) Action When winding the string, first wind the string from the inside to the outside to form the inner layer, then fit the tubular body into it and pass the string through one slit, and wind it around the outer periphery of the tubular body. Outer layer.

When making a larger ball, a cylindrical body having a larger diameter is sequentially fitted and a string is wound around the outer circumference.

The string body of this large ball is put in a string basket of a combine knotter, which is pulled out from the center side of the string ball and used for binding.

If the inner layer is pulled out by continuing the bundling work,
The string of the outer layer wound outside the cylinder is pulled out from the center side of the string ball, and the cylinder holds the string of the outer layer during that time, so there is no collapse of the string ball, and when pulling out the string of the outer layer, the tube The withdrawal side of the body has a small diameter due to the slit, so it can be withdrawn without difficulty.

(F) Embodiments An embodiment of the present invention will be described with reference to the drawings. First, when forming a string ball, the string is first wound from the inside to the outside to form a small string ball 1 serving as an inner layer, and then the bottom plate 2 is provided at one end. And a cylindrical body 5 having a plurality of slits 3 ...
Is attached to the small string ball and the string is formed into one slit 3
Then, the string is wound around the outer periphery of the cylindrical body 5 to form the outer layer 6 in this state.

In the case of making it larger, the outer layer 6 is formed as a middle layer as shown in FIG. 1 (a), and another outer layer 7 is formed on the outer periphery of the middle layer.

Then, at the time of performing the binding work, the large string balls are put in the string basket 9 of the combine knotter attached to the combine, and the end of the string 8 is pulled out from the center part thereof, and the string brake 10 and the string guides 11a and 11b are drawn. Through the binding device needle
Pass it through the string hole at the end of 12 and bind it.

When the bundling work is continued and the withdrawal of the small string ball 1 as the inner layer is completed, the string 8 is pulled out through the slit 3 to the outer periphery of the cylindrical body 5. At this time, since the cylindrical body 5 has a plurality of slits 3 ... Opened on the pull-out side, the tip side is reduced to be a truncated cone shape, and the string 8 is smoothly pulled out from the center side of the string ball 1. be able to.

Even when the number of winding layers of the string 8 is increased, the string of the outer layer 6 is sequentially drawn out in the same manner as described above, and the string of the outer layer 6 is held by the cylindrical body 5 during that time, so that the string ball is not collapsed or entangled. .

Further, as shown in FIGS. 6 and 7, in the cord brake 10, a brake shaft 15 is erected on a mounting base 13, and a hole at a base portion of a plate 16 is rotatably fitted to a lower portion of the brake shaft 15, and an upper portion thereof is provided. It is configured by fitting the holes of the bases of the upper and lower brake plates 17 and 18 to overlap with each other, and sequentially fitting the compression spring 19, the spring guide 20 and the guide receiver 21 on the upper surface of the holes and fixing them with the nut 22. The plate 16 is pulled by a spring 25 and received in a fixed posture by a stopper pin 26, and a knife 27 facing the string passing position is attached to the side surface of the lower brake plate 17 on the string pull-out side.

When an abnormally large tensile force acts on the string 8 due to a knot 28 being formed in the string drawn out from the string ball or being clogged with the string withdrawal path or the string hole of the needle, the brake plates 17 and 18 are moved as shown in FIG. B from the A position around the brake shaft 15
The cord 8 is rotated to the position, whereby the string 8 is cut by the knife 27, and it is possible to prevent the string guides 11a and 11b, the string brake 10 or the needle 12 from being deformed.

Furthermore, in the above-mentioned combine harvester, mowing threshing is performed, and the straw discharged from the culm outlet is bundled and discharged by the combine knotter, but when the work is completed and cleaning is performed, the fallen grain culm is mushed and threshed. It is necessary to open the cylinder cover 30 frequently when the straw is entangled with the straw, the foreign matter mixed in the handling room is removed, the clogged net is replaced, or the straw scythe is replaced.

However, since the cylinder cover 30 is located at a high position and has a large weight, the opening / closing operation thereof is difficult and dangerous.

FIG. 8 and FIG. 9 show a combine that solves such a problem. A step board 31 is pivotally supported by a pair of links 32 and 33 below the handle in such a manner that it can be vertically rotated. The link 33 is formed in a V shape, and the upper part of the link 33 is linked to the arm 34 fixed to the cylinder cover 30 by the connecting rod 35.
As described above, when the cylinder cover 30 is opened, the lock is released, and when the worker rides on the platform 31, the cylinder cover 30
Since the cylinder 30 opens, the cylinder cover 30 is supported by an appropriate stopper and the above-mentioned various maintenances are performed.

(G) Advantageous Effect of the Invention In the present invention, as described above, the cylindrical body 5 having the plurality of slits 3 opened on the string pull-out side is fitted on the outer circumference of the inner layer of the string ball 1, and the inner layer is formed on the outer circumference of the cylindrical body 5. Since the string 8 which is a series of the above is wound as an outer layer and the string 8 is pulled out from the center side of the string ball 1, the combine straw is used to bind the straw that is highly efficiently cut and threshed and discharged in large quantities. When discharging, it is possible to improve the work efficiency by using a large bundling string to reduce the number of ball string exchanges, but when pulling out the string of the outer layer of the string and bundling it, By holding the wound string, the string ball does not collapse and the string does not have a knot, and it is possible to prevent binding mistakes due to broken strings and deformation of the string brake, guide part, etc. .
