The figure is a rear view of the upper stay and the fixed stay.

Referring to FIG. 1, the overall structure of the self-propelled self-escape device and straw binding device will be explained.

Threshing device 1 on crawler-type traveling device 13
7. The engine room 20 and the like are arranged, and a straw binding device is fixedly installed on the straw removal side of the feed chain 25 of the shelling device 17 as in the present invention.

Reference numeral 14 denotes a grain frying conveyor, which is configured to send fine grains after threshing and sorting by a threshing device to a chute 14a, and to throw them into a paddy bag placed on a paddy bag holder 19. In FIG. 1, the rice bag holder 19 is in a stored state, and when in use, it is rotated 90 degrees to a horizontal state. 18 is a control handle.

Next, the overall structure of the straw binding device will be explained.

The entire binding device is supported on the lower parallel rails 3L, 3R so as to be able to slide back and forth, and after sliding, the fixed handles 36, 35 are used to support the binding device again on the parallel rails 3L, 3R.
Tighten and fix at R. Reference numeral 5 denotes a binding mission case, and power is transmitted to the binding mission case 5 from the threshing device 17. The upper and lower shafts are U-shaped and protrude from the binding sewing case.

A packer 16 and a binding needle 15 are rotated from a shaft projecting below the binding deck 4, and a binding clutch door 11 is also provided in a protruding manner. Further, a knot building 33, a string holder 32, and a discharge rod 12 are driven at the tip of the knot shaft protruding from above. The knot building 33 and the string holder 32 are placed inside the knot cover 10, and the discharge rod 12 is covered with the discharge cover 24.

Reference numeral 6 denotes a nodule shaft cover to which an upper stay 8, which constitutes the essential part of the present invention, is fixedly attached. The bundling deck 4 covers the lower needle 15 and the drive shaft of the packer 16, and is a cover provided so that the waste straw can flow smoothly without touching these.

The bundling deck 4 serves as a plate for the flow of the corn grains, and the bundling device is tilted downward at the front so that the grains flow smoothly toward the bag 2 for receiving the corn grains.

Further, a tip guide 7 is provided on the bundling deck 4 to float the tip of the waste straw so that the waste straw is approximately horizontal. Further, a raised edge 4a is provided at the outer end of the binding deck 4 to prevent the small grains from falling from the outer end. 1 is a sieve line that separates the grains from the straw crumbs.

The parallel rail 3, which slidably supports the entire binding device, is arranged substantially horizontally as shown in FIG. 1, whereas the binding device and the binding deck 4 are tilted forward. Since the binding device slides on the substantially horizontal parallel rails 3L and 3R, the binding device moves in parallel. On the other hand, since the upper stay protruding from the nodule shaft cover 6 is provided parallel to this nodule shaft cover 6, the threshing device 17
If there is no vertical clearance between it and the fixed stay 9 that protrudes from there, it cannot slide.

Therefore, it is configured as shown in FIG.

That is, a U-shaped holding body 9a is fixed at the tip of the fixed stay 9, and after fitting the middle part of the upper stay 8 into this holding body 9a, the roller shaft bolt into which the rollers 23 are loosely fitted is inserted. 27 is fitted and fixed to prevent it from coming off.

In addition, the sliding of the upper stay within this holding body 9a
An elastic body 22 is fixed inside to suppress vibration. The elastic body 22 minimizes sliding and vibration, and the rollers 23 facilitate forward and backward sliding.

Moreover, if the rollers 23 are made of an elastic body, vibration can still be prevented. An insertion fitting 29 is provided at the base of the fixed stay 9, and this part is inserted into the threshing device and easily fixed with a knob screw 28.

In this way, the U-shaped holding body 9a has a large structure, and in this, the upper stay 8
The inclined upper stay 8 absorbs the vertical movement relative to the holding body 9a due to the horizontal sliding of the binding device. Reference numeral 34 designates a front bracket of the upper stay 8 that projects from a part of the tuberosity shaft cover 10. The rear part of the upper stay is fixed to the tuberosity shaft cover 6.

In Figure 1, 37 is parallel rail 3L, 3R
It is the support rod for the self-propelled self-escape device, and the fuselage frame 3
It stands out from 9.

In FIG. 2, 30 is an input pulley, and 31 is a stopper spring that stops the fed straw from returning.

The parallel rail 3 is composed of an outer parallel rail 3R formed into an outer circular pipe shape and an inner parallel rail 3L formed from a square pipe. The binding device slides back and forth on these two parallel rails.

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

First, since the elastic body 22 is interposed between the holding body 9a of the fixed stay 9 and the upper stay 8, the vibration caused by the steering of the aircraft can cause the gap between the upper stay 8 and the holding body 9a to Therefore, no rattling noise is generated.

Secondly, since the upper stay of the binding device is provided in a position parallel to the knot shaft cover 6, it is possible to support the binding device almost at the center of gravity, resulting in better balance. Further, by providing the upper stay 8 in parallel to the nodule shaft cover 6, which has a high strength, the upper stay 8 can be firmly supported.

Thirdly, in the "U" shaped part of the holding body 9a,
Since the upper stay 8 is configured to absorb vertical changes, the engagement between the upper stay 8 and the fixed stay 9 has the effect that there is no need to attach or detach the straw binding device when adjusting the straw binding device back and forth. .

Fourthly, since the tip of the straw binding device is placed low, it is possible for the grains stuck in the tip to flow down to the front.
