Among the perspective views showing the support part, FIG. 10 is a perspective view with the straw binding device moved forward for extremely long culms, and conversely, FIG. 10 is a perspective view of the state where it is moved backwards for extremely short culms. Figures 11 and 12 are drawings of the binding machine mounting frame itself in front and back in embodiments with different drive systems, and Figure 13 is a diagram of the drive V-belt in the embodiments shown in Figures 1 to 10. Figure 14, a drawing showing changes due to back and forth sliding of the binding machine mounting frame, is similar to Figure 11 and Figure 1.
FIG. 3 is a diagram showing changes in the driving V-belt in the embodiment of FIG. 2;

The straw binding device of the present invention is fixed to the threshing device 22 or the shear sheath below it by means of three fixing devices in the vertical direction. Bottom part, threshing device 22
Alternatively, a sliding rail 9 is provided to protrude from the chassis in the front-back direction, and an L-shaped sliding plate 55 is placed in contact with this sliding rail 9 from the outside. The sliding plate 55 and the sliding rail 9 are fixed with two front and rear bolts 30, 30. Since a plurality of holes 9a and 9b for screwing the bolts 30 and 30 are provided on the sliding rail 9 side, by selecting these holes 9a and 9b, the binding machine can be slid horizontally back and forth from the binding machine mounting frame. It is possible to adapt to extremely long or extremely short culms.

In addition, only the binding mechanism can be slid in order to make fine adjustments along the direction of inclination of the opening. Further, the straw binding device is fixed in the middle between the hook body 14 and the front and rear support culms 15b. The front and rear support culms 15b are the supports 15a, 1
The front and rear parts of the threshing device 22 are connected to the threshing device 22 by means of 5b, and the hook body 14 can be freely hooked anywhere between the threshing devices 22 and can also be slid back and forth in the hooked state.

Further, at the upper part, a connecting rod 32 is fixed to a support 33 projecting from the discharge rod base 4e so as to follow the back and forth movement of the straw binding device. After adjusting by sliding back and forth, the length of the connecting rod 32 is fixed by tightening the fixing bolt 34 by grasping the handle and turning it.

In this way, the straw tying device A is fixed to the threshing device 22 or the shear sea at the top and bottom three points, but when the straw tying device A is first fixed to the threshing device, it is lifted and the hook body 14 is moved back and forth. It is hooked onto the support culm 15b. This temporarily fastens the slide plate 55, then places the slide plate 55 on the slide rail 9, aligns the front and back directions, and fixes it with the bolts 30, 30.Finally, adjusts the binding mechanism by sliding it back and forth. Later, the length of the connecting rod 32 is tightened and fixed with the fixing bolt 34.

The binding machine mounting frame portion is constructed based on the sliding plate 55. That is, the front frame 2
9 and the rear frame 74 are erected as supports from the sliding plate 55, and the outer frame 28 is erected outward from the reinforcing plate installed between the front frame 29 and the rear frame 47. The inclined sliding bodies 60 and 62 of the binding mechanism are supported by the frame of the book. As shown in FIG. 2, a sliding receiving plate 28a is provided at the upper end of the outer frame 28, and an inclined sliding member 60 is slidably mounted on the upper surface of the sliding receiving plate 28a. Further, a sliding receiving plate 28a is formed at the upper end of the front frame 29, and an inclined sliding body 62 is slidably placed on this receiving plate 28a. Further, a sliding receiving plate 47a is provided at the upper end of the rear frame 47, and the curved upper part of the rear part of the inclined sliding body 62 is placed on this. The sliding receiving plates 28a, 29a, 47a are made of L-shaped metal fittings, and the inclined sliding bodies 62, 60
is made up of pipes, but only in one place are the three frames and the inclined sliding body that are tightened or loosened. In the tightening handle 12, an L-shaped plate for tightening both is fixed to the inclined sliding body 60. As shown in FIGS. 2 and 3, the fastening handle 12 is
By pressing strongly downward, the space between the sliding receiving plate 28a and the inclined sliding body 62 is tightened, making sliding impossible.

The above is a device for making stepless fine adjustments to the waste straw of long and short culms, but this alone is not sufficient for extremely long and extremely short culms, and The entire operation is performed between the sliding rail 9 and the sliding body 55.

The sliding rail has three screw holes 9a, 9a in the front part, and three screw holes 9b, 9b in the rear part. On the other hand, when the sliding body is slid and adjusted, the threshing device 22
While the PTO pulley 37 protruding from the tying machine frame is fixed, the intermediate pulley 17, tension pulley 16, and input pulley 39, which are supported by bearings on the tying machine frame, move together with the tying machine frame. , it is necessary to prepare V-belts of different lengths for each adjustment of the extra-long culm.

In order to deal with this, screw holes 56a, 56b and 2 are used to support the intermediate pulley 17 on the reinforcing body 56.
The screw holes 56a, 56b and the screw holes 9b, 9b are provided at the same distance, and by changing the position of the hole where the bearing is installed and adjusting the bearing position of the intermediate pulley 17, the overall Therefore, the belt length does not need to change.

Further, since the tensioning direction of the tension pulley 16 changes, the tensioning position of the tension spring 31 is changed between the locking tools 58 and 59 to tension it in the optimum direction.

In the embodiment shown in FIGS. 11 and 12, a PTO pulley 57 projects from the engine section at the front of the thresher, and in this case, the intermediate pulley 17 is configured to move rearward.

This pulley relationship is shown in FIGS. 13 and 14. The solid line indicates the case where the culm slides to the extremely long culm position, and the broken line indicates the case where the culm slides to the extremely short culm position.

FIG. 13 shows the case in the embodiments from FIG. 1 to FIG. 10, and when the binding mechanism is slid, the PTO pulley 37 does not move and the intermediate pulley 17 is moved between the screw holes 56a and 56b. However, when the binding mechanism slides back and forth, it does not move.
The input pulleys change to 39' and 39, and the tension pulleys change to 16' and 16.

Fig. 14 also shows a case where the binding mechanism slides back and forth, but the PTO pulley 57 does not move, and the intermediate pulley is replaced back and forth, but it does not move when the binding mechanism slides, and the input pulley ends up 39,3
9' and the tension pulley moves to 16,1
It moves 6'. As a result, there is no longer a need to prepare multiple V-belts.

As shown in FIGS. 9, 11, and 12, two tubes 49, 49 are fixed to the front frame 29, and the strap case 18 is configured to be easily attached to and detached from the tubes 49, 49. There is.

As shown in FIG. 8, arcuate plates 26, 26 are fixed to the outer periphery of the binding string case 18, and two pins 19, 19 are fixed to the arcuate plates 26, 26 in the front-rear direction. The front ends of the pins 19, 19 are inserted into the tubes 49, 49, and after insertion, a pine needle pin 27 is inserted into one tip of the pin 19 to prevent it from coming off.

In addition, the input pulley 39 is connected to the bevel gear box 4.
The power is transmitted within the bevel gear box 40, and the power is changed in the direction of the inclined sliding bodies 60 and 62, and the power is transmitted to the binding mission case 1. As the binding mechanism slides relative to the inclined slides 60, 62, the bevel gearbox 40 also moves together with the input pulley and tension pulley 16. This change in the V-belt length is absorbed by the tension pulley 16.

The binding mechanism covers the top cover 10,
The lower part is covered by a front cover 11, a side cover 35, a rear cover 44, a rear upper cover 36, etc. for the safety of the operator. and,,
Guide rods 45 and 46 protrude from the side view cover 35, and a guide plate 43 protrudes toward the feed chain 24 from the upper part of the front cover 11, with its tip 43a
is protruded slightly downward to prevent the straw from falling from the feed chain 24's gripping rod 25 without being caught by the raking packer. or,
A stock lifting board 42 is erected above this guide board 43 to prevent the waste straw from becoming too dry and becoming soft and hanging down at this part.

At the end of the feed chain 24 of the threshing device, the straw wrapping prevention rod 7 is removed from the chain sprocket 8 section.
is provided in a C shape, and the right end of the straw wrapping prevention rod 7,
The distal end portion of the intake guide 2 protruding to the left side from the knot cover 5 of the binding device is wrapped in the front direction. This forms the upper guide part of the straw removal passage. In addition, the lower side of the straw drainage passage is connected to the guide plate 43 and the protrusion 4 from the clamping rod 25 of the feed chain 24.
It consists of 3a. The rotation locus B of the raking packer 6 overlaps the right end of the straw wrapping prevention rod 7.

These structures guide the straw removal of the tying machine and
The raking action is now reliable, and there is no longer any disturbance in conveyance due to upward lifting, especially in the case of large bundles. Moreover, the overlap between the straw wrapping prevention rod 7 and the rotation locus of the raking packer further improves the effect of preventing straw wrapping.

In addition, in FIG. 5, the intake guide 2 provided at the tip of the tuberosity cover of the binding mechanism forms a downwardly inclined edge 2a that gradually slopes downward as it enters from the entrance side when viewed from the front, and enters under the tuberosity cover 3. This time constitutes a vertical edge 2b that stands up substantially vertically.
With this configuration, the waste straw is smoothly guided to the bundling part by the downwardly inclined edge 2a, and once it enters the bundling part, it is prevented from flowing back to the inlet part. In the case of self-propelled self-elimination, unlike freshly cut grain culms, the moisture has been removed and the grain culms have become soft, so even if you scrape them up with a packer, they will swell up again due to their flexibility and return to the inlet. This problem has been solved by getting caught between the needles and causing clogging and knotting.

Also, among the release arms 4a, 4b, 4c, and 4d, the release arms 4a and 4b on the stock side are bifurcated, and the release arm 4b on the upper side in the release direction performs the conventional release action, while the other release arm 4a The flexible waste straw that enters the bundling part and is stored in the bundling part is overflowed, and the bundling part is designed to catch the untied waste straw so that the bundling does not become irregular. Furthermore, a leaf spring 3 made of a spring plate for holding the tip is fixed from the supporter 33 of the discharge arm base 4e, and the leaf spring is bent into a C shape and extended to the top of the bundling part, and just above the tip of the straw. It was designed to be held down from the This is because the bundled waste straw is tied diagonally, so it is held down to prevent it from slipping off the tip of the ear.

In addition, as shown in FIG. 7, three pieces of the raking packer 6, 6c, 6b, and 6a, rotate at once from the stock base to the upper part. The position of the feed chain cannot be adjusted between the packers 6c and 6a by sliding adjustment. When the mounting frame is set at a position corresponding to an extremely short culm, it is impossible to adjust the distance between a and a. When the mounting frame is set at the position corresponding to the extremely short culm, the sliding adjustment by the inclined sliding of the binding device can be adjusted within the distance a.

In this way, the feed chain can be moved between the patrol cars 6, and the optimum inheritance can be selected.

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

First, since the sliding plate 55 slides on the sliding rail 9, the entire straw tying device including the tying mechanism can be largely adjusted back and forth in the direction of movement. Sliding body 6 tilting the mechanism part
0.0, 62, it can be adjusted in two ways: adjusting for long and short culms, and preventing gaps from forming between the joint part of the feed chain 24, resulting in soft drying. Even though it was a waste of straw, we were able to capture it and tie it together.

Second, to attach the straw binding device to the threshing device 22, first attach the hook body 14 to the front and rear support culms 15b.
Since it is possible to temporarily fix the slide plate 55 and the slide rail 9 by hanging it, and then adjust the gap between the slide plate 55 and the slide rail 9, it is possible to fix the slide plate 55 and the slide rail 9 at the optimum position.
