The binding machine C of the present invention is attached to the side of the body of the feed chain 9 on the exit side, and the frame 10 of the binding machine C is attached.
A binding mission case with a door 11 and a packer attached and a deck 12 are provided on the top of the chain, and a transmission pipe protruding forward from the upper end of a chain case 13 standing upright at the rear.
A knotting device and a discharge arm 15 are arranged at the front end of the device.

Power is transmitted to the binding mission case from a power take-off shaft provided on the side of the machine body via a gear case 16, a transmission shaft 17, and a transmission case 18.

Further, a side view type auxiliary frame 20 is fixedly installed below the frame 10, and mounting plates 23, 2 for the front stand 21 and the rear stand 22 are provided on both the lower front and rear sides of the auxiliary frame 20.
4,25,26 are fixed.

A shaft is laid horizontally between the mounting plates 23, 24 and between the mounting plates 25, 26, and a front stand 21 and a rear stand 22 are pivotally supported on both sides of the shaft so that they can be fixed at the storage position and the projecting position.

That is, the fixed portion of the mounting plate 26 of the front stand 21 on the front side will be described with reference to FIGS. 4 and 5.

An upper end of a rotation base of the front stand 21 is rotatably supported by a shaft 27, and a U-shaped bracket 29 having an open front is fixedly provided on the front side of the rotation base of the front stand 21. Mounting plate with bracket 29 penetrating locking pin 30 from the side
26 can be engaged. The locking pin 30 is a bracket
The spring 31 is externally fitted inside the spring 29 and is urged in a direction of protruding. 30a is a handle.

On the other hand, the mounting plate 26 has pin holes at the projecting positions of the locking pins 30 in a state in which the front stand 21 is set up and in a state in which the front stand 21 is stored.
The openings 26a and 26b are opened, and by inserting and removing the locking pin 30, it is possible to fix the standing position and the storage position.
The rear stand 22 and the mounting plate 24 can also be fixed to the standing position and the storage position by the locking pin 31 as described above. In addition, casters 32 are attached to the lower end of the rear stand 22.
Is attached, and the front side is floated with the binding machine C removed so that it can be easily moved.

As for the attachment / detachment mechanism of the binding machine C, as shown in FIGS. 3 and 6, on the rear side, a U-shaped rear fitting body 33 in plan view is fixedly installed on the side surface of the frame 10 with the body side open. The rear mounting pipe 41 fixed to the side surface of the threshing device D can be fitted.

Reinforcing plates 34 and 36 are fixed to the lower part of the center of the rear fitting body 33, and a rear lock plate is provided on the upper part of the rear fitting body 33.
35 are arranged and are pivotally supported by pivot pins 37 standing on the reinforcing plate 34.

The rear lock plate 35 is biased in the locking direction by a torsion spring 38 fitted onto the pivot pin 37. 39 is a stopper fixed to the side surface of the fitting body, and 40 is a handle fixed to rotate the rear lock plate 35.

As shown in FIG. 7, on the front side of the attachment / detachment mechanism, an L-shaped mounting plate 43 in plan view is fixedly mounted on the rear side of the frame 10, and reinforcing plates 44, 45 are fixed on the upper and lower side surfaces of the mounting plate 43. Has been done.

On the rear side of the reinforcing plates 44, 45, a front fitting body 46 having a U-shape in plan view is fixedly installed with the rear open, and can be fitted to the front mounting pipe 42 fixed on the side surface of the engine room E. There is.

A front fitting body is attached to a pivot pin 49 which is erected on the reinforcing plate 44.
A front lock plate 47 arranged on the upper part of the shaft 46 is pivotally supported, and a torsion spring 50 externally fitted to a pivot pin 49 biases the front lock plate 47 toward the lock side. 53 is a stopper.

Also, attach the rod to the side opposite to the hook of the front lock plate 47.
51, and the other end of the rod 51 is pivotally connected to the lower end of a front detachable handle 52 pivotally supported near the rear fitting 33, and the front detachable handle 52 is operated from the rear side to lock the front portion. The plate 47 can be released and rotated.

Then, as shown in FIG. 8, an elevating support 54 is provided for receiving the front fitting 46 when fitted to the front mounting pipe 42.

That is, the lifting support body 54, the locking pin 55 is erected on the upper surface,
A cam portion 54a is formed on the lower surface of the front mounting pipe 42. The front mounting pipe 42 has a cam portion 56a that engages with the cam portion 54a. It is fixed at 42.

Therefore, when the raising / lowering support body 54 is rotated along the hypotenuses of both cam portions so that the concave portions and the convex portions of the cam portion 54a and the cam portion 56a are engaged and matched with each other, as shown in FIG. When the height of the upper surface of the body 54 is lowered and the convex portions are brought into contact with each other by rotating in the opposite direction as shown in FIG. 8, the height of the upper surface of the elevating support body 54 may be at a high position. You can do it.

(F) Operation of the device With the above configuration, when the binding machine C is removed from the mounted state, the locking pins 30 and 31 are pulled, the lock is released, and the front stand 21 and the rear stand 22 are rotated. The rear detachable handle fixed in the rear lock plate 35 after being moved upright and fixed again with the locking pins 30 and 31.
By rotating 40, the lock is released and the front mounting pipe 42 is rotated as shown in FIG.

At this time, the raising and lowering support body 54 is rotated by engaging the locking pin 55 with the fitting body 46, and the height becomes low as shown in FIG.
The front stand 21 and the rear stand 22 also reach the ground.

Next, when the front detachable handle 52 provided on the side surface of the frame 10 is rotated, the front lock plate 47 is released, and the binding machine C can be completely removed from the main body by moving the front lock plate 47 to the side in that state. Of. Further, in the case of mounting in reverse, the above operation may be performed in reverse.

(G) Effects of the Invention With the above-described structure and operation, the present invention has the following effects.

First, since the stand can be set up below the binding machine and the attachment / detachment handle provided at the rear part can be rotated to carry out the attachment / detachment work of the binding machine, it is not necessary to lift the binding machine, and it is not necessary for a woman or an elderly person. Even a weak worker can now easily be attached and detached by a single worker.

Secondly, since the lock state of the rear lock plate and the front lock plate can be released by rotating the detachable handle provided on the rear side, it is not necessary for the operator to move back and forth, and the side close to the operation handle 4 on the rear side. At the position of, you can perform the detaching operation.

Thirdly, the rear fitting body and the front fitting body can be fitted to the rear mounting pipe and the front mounting pipe that are fixedly installed on the side of the self-propelled self-propelling device. The rear lock plate and the front lock plate are arranged so that they can be engaged with each other, and the binding machine is attached and detached by operating this lock plate with the attachment and detachment handle. Instead, it can be easily attached and detached, and parts are no longer lost.
