Description

[Detailed description of the invention] The present invention relates to a waste straw binding device attached to a threshing device, for example, for binding horizontally fallen stem culms. ) It is an object of the present invention to provide a bundling device that can smoothly converge and bind without causing JP disturbance.

The bundling device of the present invention is arranged such that the waste straw bundling device is disposed at a position away from the end of the waste straw conveying device for conveying the side-falling stem culm, and the waste straw bundling device is tied from the terminal end of the said waste straw conveying device. A conveying path leading to the space is provided so as to be inclined diagonally downward as it reaches the rear, and a knot part and a string supplying part are vertically opposed to each other in order to tie the waste straw at a substantially central position in the culm length direction, and the conveying path is , in the binding device comprising a pair of upper and lower covers that cover the knot part and the string supply part, the knot part and the part of the cover in the length direction of the discharged straw culm of the upper cover and the lower cover forming the conveyance path are The part facing the string supply part is characterized by protruding inward of the conveyance path from a portion of the stock-side cover and a portion of the tip-side cover on both the left and right sides. Because the central part is supported and the central part is raised in a curved shape as it moves along the conveyance path, it may unexpectedly shift laterally during movement [7, the puller may fall, or The user's posture is not disturbed, and the contact resistance with the upper and lower walls has been reduced, making it possible to move smoothly.

In addition, since the conveyance path portion in which the knot portion and the string supply portion are arranged facing each other is extended from the start end to the end end of the conveyance path, and is narrowed by protruding inwardly from the conveyance path portions on both sides, for example, the knot The conveyance path portion in which the part and the string supply part are arranged facing each other,
There is no risk that the conveyance path becomes narrow in the middle and the posture is distorted due to straw clogging in the narrow part, unlike when the conveyance path is narrowed from the middle.

Furthermore, in the case where the conveyance path portion in which the knot portion and the string supply portion are disposed facing each other is configured to be narrower by protruding inward than the conveyance path portions on both sides, it is difficult to concentrate the stem culms in the binding space. By tightly converging and tying in this manner, it has become possible to eliminate the conventional problem in which the stem culm moves during the tying operation, causing the string to dance and causing knotting mistakes.

Next, an embodiment of the present invention will be described.
The waste straw binding device 2 attached to the will be explained.

A pair of upper and lower covers 17 and 18 are provided along the lateral direction so that the entrance to the transport path 40 faces the terminal end of the waste straw transport device 3 arranged at the rear of the threshing device 1, and the exit is arranged below and rearward from this entrance. It is arranged so as to be inclined rearward and downward.

Then, at approximately the center in the lateral direction of this conveyance path 4 and above the rear portion thereof, there is disposed a knot 10 constituted by providing a building 1, a holder 8, and a timing gear 9, and a needle JL/11 is disposed on the lower side. , and a discharge arm 12 which also serves as a door, is arranged, and a binding space 14 is formed between the two parts 10° 13.

The conveyance path 4 leading to the bundling space 14 is configured as described below.

That is, the upper cover part 5 on the stock side side and the cover part 5' on the tip side of the upper cover 17 that covers the nodule part 10 are moved upwardly in a state □ along the lateral side of the nodule part 10 with respect to the cover part 15 that covers the nodule part 10. After being bent, the bottom cover part 6 and the tip part 6' of the lower cover 18 extend laterally from the upper and lower middle parts of the knot part 10 and cover the string supply part 13.
The cover part 16 covering the string supply section 13 is bent downward along the lateral side of the string supply section 13, and then extended laterally from the upper and lower intermediate parts of the string supply section 13, The conveyance path portion where the knot portion 10 and the string supply portion 13 are disposed facing each other is configured to be narrower in the vertical direction than the conveyance path portions on both sides.

A bracket 19 is provided on the plant base side cover part 6 of the lower cover 18 so as to be able to be displaced and fixed in the culm length direction of the waste straw to be bundled, and this bracket 19 is provided with a plant base support rod 20 and a plant base alignment plate 21. be.

Reference numeral 22 denotes a leaf spring for the stock base, which is fixed to the stock base side cover portion 5 of the upper cover 17.

23 is a U-shaped transmission case that connects the knot section 10 and the string supply section 13, and 24 is a packer disposed on the entrance side of the conveyance path 40.

Reference numeral 25 denotes a release direction regulating device, which has an arm 26 pivotably supported in the middle part of the U-shaped transmission case 23 so as to be swingable in the direction of entry and exit of the conveyance path 4, and has a tip-holding no-noh member 27 at the free end of the arm 26. The arm 26 is biased by a spring 28 in the opposite direction to the discharge direction, and the discharge action of the discharge arm 12 rotates the bundled waste straw around the pivot axis of the arm 26 and discharges it. That's how it is.

The present invention can also be easily applied to a binding device attached to a threshing device mounted on a harvester.
