A double-pitch type roller chain 50 is wound between 6 and the tines 51.5 are arranged on the chain 50 every other pitch.
1 ... is supported. Then, the tine 5 is provided inside the drive sprocket 35 and the driven sprocket 36.
A regulating plate and a tension spring for arranging 1 in a predetermined direction are arranged.

The tine 51 is integrally molded of synthetic resin. The tine 51 is composed of a vertically long plate-like member having an L shape in plan view, and a central portion thereof is pivotally supported by the chain 50. There is. The plate protruding to one side of the tine 51 is brought into contact with the regulation plate, the plate on the other side is brought into contact with the straw J, and the contact portion is contacted at a substantially right angle with the culm end, A receding angle is formed so that the grain culm is not caught at the end of conveyance.

A bevel gear 37 fixed on the upper end of the drive shaft 33 and a bevel gear 38 fixed on the binding input shaft 40 are housed in a gear box 39, and the binding input shaft 4
Numeral 0 drives the binding machine K and the stock transporter H, and power is transmitted from the high-speed rotation shaft 13 to the binding input shaft 40. That is, the high-speed rotating shaft 13
Is lower than the straw conveying path, the bundling input shaft 40 is located above the straw conveying path, and the packer 23 driven directly by the bundling input shaft 40 needs to slow down its rotation. A transmission shaft 44 is arranged between the shaft 40 and the high-speed rotation shaft 13 at a position lower than the straw transfer passage and closer to the high-speed rotation shaft 13, and the belt 46 and the transmission shaft 44 are arranged from the pulley 21 on the high-speed rotation shaft 13. Power is transmitted to the input sprocket 41 on the binding input shaft 40 via the upper transmission pulley 45, the sprocket 43 on the transmission shaft 44, and the chain 42.

The stock aligning plate 30 is pivotally supported on a pivot fulcrum 55 provided at the rear of the drive shaft 33, and its front end extends to the side of the rear part of the stock carrier H. As shown in FIG. 5, one end of a connecting link 56 is pivotally connected to the rotation base side of the original aligning plate 30, and the other end of the connecting link 56 is connected to a swing arm 57 and a swing link 58. The other end of the swing link 58 is pivotally connected to a side surface of the input sprocket 41, and the stock shunt aligning plate 30 is swing-driven by the rotation of the input sprocket 41. Therefore, when the power from the high-speed rotating shaft 13 is transmitted to the input sprocket 41, the stock linking plate 30 is driven by the swing link 58, and the binding input shaft 4
From 0, the stock carrier H and the binding machine K are driven.

The straw guide plate 22 is provided behind the cutter switching cover 10, and the straw guide plate 22 is provided.
A binding machine K is arranged at the left and right central portions of. The binding machine K
The upper binding mission case 18 is located above the straw guide plate 22.
Are arranged, the packer 23, the needle 24, the door 25
And the like, and the lower binding mission case is arranged below the straw guide plate 22 to arrange the knot 26 and the discharge arm 27. Then, a bundling device G is arranged behind the binding machine K, and the bundling device G has a guide plate 28 (FIG. 1) arranged on the rear extension of the straw guide plate 22 and above the conveyor belt 2.
9 (FIG. 6) are arranged.

In such a structure, when the threshing straw J after threshing is taken over from the feed chain 5 to the straw chain 7 with the cutter switching cover 10 covering the upper side of the cutter device C, the straw J is left and right. It is conveyed diagonally rearward while facing the direction, and at this time, the root end of the straw J is brought into contact with the tine 51 of the root carrier H at a right angle and forcedly conveyed. At the end of the conveyance, the root end of the straw J is beaten and aligned by the swing of the stock alignment plate 30, and the straw is conveyed to the binding space of the binding machine K and pushed by the packer 23 to a predetermined amount. When the straw is collected and the door 25 is rotated, the needle 24 is rotated, the knot is driven and knotted, and the knot is sent to the bundling device G by the discharge arm 27 and discharged to the field. .

[0018]

The present invention is configured as described above.
The following effects are obtained. That is, the binding input shaft, the packer, the needle and the door are arranged above the straw discharge passage of the binding machine, and the knot and the discharge arm are arranged below the straw discharge passage.
Since the power is transmitted to the binding input shaft through the transmission shaft arranged below the high-speed rotation shaft of the cutter device in a side view, power can be transmitted while avoiding the straw passage. The high-speed rotation shaft can be arranged close to each other, and the member between them can be made small. Also, since the rotation speed of the high-speed rotating shaft is decelerated in stages, the reduction ratio can be increased, and even if the pulley diameter provided on the high-speed rotating shaft is small, a predetermined transmission force can be obtained and the structure is compact. it can.

Further, since the transmission gear and the input sprocket are fixedly mounted on the binding input shaft, and the stock conveyor is driven by the transmission gear, the stock conveyor is directly driven by the binding input shaft. As a result, the transmission mechanism can be simply configured to reduce the cost. Further, since the input sprocket is configured to drive the stock aligning plate via the link mechanism, the link mechanism can be arranged outside and driven from the outside, and does not interfere with the straw passage, and maintenance is also possible. It's easier to do.
