Description

[Detailed explanation of the invention] Conventionally, the root alignment plate of the combine tying machine was driven by a drive shaft separate from the tying machine, but when the root alignment plate was driven from outside the root side of the straw removal path, the The transmission mechanism protrudes outward and gets in the way, and if it is driven from the panicle side, the distance between the rooting plate and the support part of the drive shaft must be made approximately equal to the culm length, and the rooting plate will deviate greatly from the support part. Because it is supported by the tip of the drive shaft that protrudes in a vertical direction, the operation of the leveling plate becomes unstable even if the strength of the drive shaft is extremely high, and furthermore, the drive mechanism of the leveling plate becomes an obstacle to straw removal. There were various drawbacks such as.

In order to improve the above-mentioned drawbacks, the present invention provides a combine tying machine in which a tying machine equipped with a bucker, a needle, and a knot part is installed in the straw discharge section of a threshing device, and the input shaft of the transmission case of the tying machine is It is made to extend toward the stock side avoiding the straw raking path, and this extending portion is rotatably supported by a support frame, and an input rotating wheel is attached to the extending portion, and the input rotating wheel and the transmission case are rotatably supported by the supporting frame. A reciprocating drive mechanism is installed between the tying machine and the reciprocating drive mechanism, and a root leveling plate for aligning the base portions of the straw collected by the collecting rod of the binding machine is interlocked and connected to the reciprocating drive mechanism.

The embodiment shown in the drawings will be explained below.1
is a threshing device mounted on a combine machine base 3 having a traveling device 2, and a desk-shaped cutter 5 with side plates 4, 4 protruding rearward is attached to the rear of the threshing device. A tying machine 9 is provided above with a raking path 6, a collecting rod chamber 7, and a condensing chamber 8 separated from each other.

Reference numeral 10 denotes a straw conveying chain extending from the discharge rod opening of the threshing device 1 to the top plate of the dust sorting chamber 11 and onto the cutter 5, and the binding device 9 faces the discharge section thereof.

Further, the binding machine 9 moves the front part of the transmission case 12 laterally via the support arm 15 to the pipe 14 installed between the support frames 13, 13 installed upright on both side plates 4, 4 of the cutter 5. The rear part is fixed to a pipe 16 installed between the protrusions 4a, 4a of the side plates 4, 4 so as to be adjustable in lateral movement, and the transmission case 12 has a front part. Input shaft 18 which also serves as the first gear shaft in order from
A second puller shaft 19 and a knot shaft 20 are supported, and the input shaft 18 and the second puller shaft 19 protrude to both left and right sides of the transmission case 12. 21 is
Further, the second packer shaft 19 has a transfer packer 2.
2 and 22 are installed.

Further, the nodal shaft 20 drives the nodal part 20a consisting of a bill and a holder, and the sweeper 23, and also drives the lower needle 2 through a crank arm and a connecting rod.
Drive 4.

The stock end side of the input shaft 18 extends directly above the side plate 4 while avoiding the straw raking path, and is rotatably supported by the support frame 13, and becomes an input rotating wheel and the input sprocket 25 is connected to the cutter. Sprocket 2 of the rotating shaft to which the disk blade 26 is attached
7 through a chain 28, and the shaft of the star foil blade 28' is rotated in the opposite direction by the rotation shaft through a gear.

A fixed cam 29 is fixed with a bolt between the input sprocket 25 of the input shaft 18 and the transmission case 12, and is further elastically biased by a spring 30 received by a stopper 33 on the stock side. A slide collar 31b is loosely fitted, and a movable cam 31 is attached to this slide collar 31a via a bearing.
A root alignment plate 34 is screwed onto the arm 31a hanging down from the support frame 13, and a pair of guide rods 35, 35 protruding from the support frame 13 toward the front and rear of the movable cam 31 as shown in FIG. The arm 31 as shown in
The root alignment plate 34 is held in a substantially constant position close to the front and rear surfaces of the base of a. In the drawing, 36 is a cover that covers the upper surface of the straw removal route, 37 is a knot guide, and 38 is a cover for the binding machine 9.

In the above-mentioned apparatus, when the cutter 5 shreds the waste straw sent later by the waste straw conveying chain 10, the switching plate 39 is opened and the straw is fed to the cutter 5, and when the waste straw is bundled and discharged, the switching plate 39 is closed. 1st police car 2
1 and 21, as shown in FIG.

At this time, the fixed cam 29 attached to the input shaft 18 that constantly drives the first pack cars 21, 21 also rotates at all times, causing the movable cam 31 rotatably supported to move laterally against the spring 30. The root alignment plate 34 attached to the movable cam 31 also reciprocates in the lateral direction to strike the root part of the straw that is raked into the stock base and the panicle side by the first packers 21, 21. When the door 40 senses that the amount of culms collected in the collecting culm chamber 7 has reached a predetermined amount, the one-turn clutch of the second packer shaft 19 engages and the transfer packer 22 collects the collected waste straw. is drawn into the speed-coupling chamber 8 all at once and stopped at the maximum compression point.

On the other hand, when the second packer shaft 19 rotates 300 degrees, the one-turn clutch of the knotting shaft 20 is activated via the delay mechanism, and as the knotting shaft 20 is activated, the needle 2 is rotated.
4 hangs a string, and when the knotted part 20a knots, the sweeper 23 discharges the straw bundle while removing the knots.

As described above, the present invention is a combine tying machine in which a tying machine equipped with a bundler, a needle, and a knotter is installed in the straw discharge part of a threshing device, and the input shaft of the transmission case of the tying machine is used to remove straw. The extending portion is rotatably supported by a support frame, and an input rotating wheel is attached to the extending portion, and between the input rotating wheel and the transmission case. A reciprocating drive mechanism is installed, and a root leveling plate for aligning the stock base of waste straw scraped into the culm collecting part of the bundling machine is interlocked and connected to the reciprocating drive device, so that the purpose is to drive the root leveling plate. For example, if the input shaft is extended from the transmission case to the opposite side from where the input roller is installed,
Alternatively, there is no need to provide a separate drive shaft, and power can be transmitted to the drive mechanism of the alignment plate between the input rotation wheel of the input shaft and the transmission case of the tying machine, thereby making it possible to transmit the power to the alignment plate. The structure of the transmission device can be significantly simplified and costs can be reduced, and the driving device for the leveling plate does not become an obstacle to raking straw, and the leveling plate can be accurately driven.
