The position changes automatically.

The following description will be made based on the embodiments shown in the drawings.

Referring to FIGS. 1 to 3, A is a reaping and tying machine, which can travel in wet fields with a wet paddy sled 1, running wheels 3 with paddy lugs 2, a cutting blade 4, and a pulling device 5.5. ', binding device 6
A reaping binding section consisting of a transport plate 7 is provided in the front part, an engine 8 and a handle 9 are provided in the rear part, and the engine 8 is supported by one running wheel 3, and the power of the engine 8 is transmitted to the running wheel 3 through an appropriate transmission mechanism. At the same time, the power of the engine 8 is transmitted to each element of the reaping and bundling section via an appropriate transmission mechanism, and the bundling culm M is sent to the side of the machine from the outlet on the side of the center of the machine. The direction is configured to emit.

As shown in Figs. 4 and 5, the shell culm accumulation device B has a hull structure of a longitudinally rectangular shape with four raised peripheral parts 12, molded with lightweight materials such as PPP, other reinforced plastics, and aluminum. A towing fitting (towing pipe) that connects the accumulated ship 10 via a towing coupling device (towing link) 19
15 is installed on the side of the culm release side of the above-mentioned reaping and tying machine A, and on the bottom surface 11 of the stacking vessel 10, there is a groove installed on the inner side in order to improve the straightness of the stacking vessel 1o and increase the strength of the hull. A protruding rib 13 is formed.

The traction fitting 15 has a support rod part (hereinafter referred to as a vertical rod part in the description of the embodiment) that is located on the side of the reaping and binding machine A and is parallel to the reaping and binding machine A in the vertical direction (longitudinal direction of the machine body) in a plan view. )1
6 and a traction support part 17 formed by bending the tip extension part of the vertical rod part 16 outward, and the vertical rod part 16 is fixed to the side of the reaping and tying machine A so that its mounting position can be changed freely. In the fixed state, the traction fitting 15 moves back and forth integrally with the reaping and tying machine A.

Hooks 18 are fixed to two places on the left and right sides of the towing support part 17, and one end of the towing coupler 19 is engaged with a hole 21 of an ear 20 formed in the front peripheral edge 12a of the stacking ship 10, and the other end is attached to the hook 18. When engaged, the stacker 10 can be freely moved laterally and vertically when the stacker 10 and the tow fitting 15 are connected, and the stacker 10 can be rolled and pitched.

6 and 7 show a mechanism for fixing the vertical rod part 16 of the traction fitting 15 to the reaping and binding machine A so that its position can be changed in the front and back direction, and the transmission case of the binding device 6 of the reaping and binding machine A. A support fitting C' is formed by penetrating a hole 24 in the front and rear direction in a support plate 23 suspended from a mounting plate 22 fixed to the nodule shaft side of the upper surface 6a, and an angle fixed to the rear end of the transmission case together with a rear cover 25. A support plate 27 welded to the support plate 26 is provided with a support fitting C formed by penetrating a hole 28 in the front and rear direction,
The vertical rod portion (round pipe) 16 of the traction fitting 15 is inserted into the holes 28 and 24 of the support plates 27 and 23 of the support fittings C and C', so that the traction fitting 15 can be freely slid and rotated in the front and rear direction. By inserting a pin 29 into the rear end of the vertical rod portion 16, the movement range of the vertical rod portion 16 is limited (preventing it from separating from the support plate 27).

Furthermore, a locking device 30 is provided for the vertical rod portion 16, and when the locking device 30 is operated, the traction fitting 15 is integrally fixed with the reaping and tying machine A, and is moved together with the reaping and tying machine A, and when the locking device 30 is released, the reaping and tying is performed. The machine A moves forward independently of the accumulation ship 10, and the relative longitudinal positional relationship between the two can be changed freely.

Referring to FIGS. 7 and 8, this locking device 30 has a hole 37 corresponding to the hole 26 of the support plate 27 at the lower end of a lock plate 32 located behind the support plate 27 and pivoted by a pin 31. [It is larger than the cross section of the vertical rod part 16 and fits loosely with the vertical rod part 16] is installed by inserting the end of the wire 34 inserted through the support metal 33 welded to the upper end of the support plate 27 to the upper end of the lock plate 32. A compression spring 35 is interposed between the lock plate 32 and the support metal 33, and the other end of the wire 34 is connected to the lever 3 on the bundle 9 side.
6, and normally locks the lower edge of the hole 37 of the lock plate 32 with the vertical rod portion 16 of the traction fitting 15 by the pressing force of the compression spring 35 to prevent movement of the vertical rod portion 16. The lock plate 32 is brought into the locked state (the elastic connected state) (the state shown by the solid line in FIGS. 7 and 8), and the lower end of the lock plate 32 is rotated forward by the rotation of the lever 36, thereby the unlocked state (the eighth
change to the state shown by the chain line in the figure).

The compression force of the compression spring 35 that presses the lock plate 32 is
The vertical rod portion 16 receives the vibration impact generated by the reaping and tying machine A and the culm accumulating device B and the traction resistance that the culm accumulating device B receives.
The spring load is set so that rattling occurs between the lock plate 32 and the lock plate 32.

In other words, if the spring load of the compression spring 35 is greater than the spring load of the compression spring 35, the lock state is applied to vibration shocks in the longitudinal direction of the support rod 16 of the traction fitting due to the shaking of the stacker due to stumps or other irregularities in the field, engine vibration, etc. is released, and the locked state will not be released in response to a vibration impact smaller than the spring load.

In the above-mentioned support fittings C and C', the holes 28 and 24 for inserting the vertical rod part 16 in the support plates 27 and 23 correspond to the cross-sectional shape of the vertical rod part 16 of the traction metal fitting, and have a slightly larger cross-sectional area. It has become what is called a stupid hole.

In the embodiment, the vertical rod portion 16 is formed of a round pipe and has a circular cross section, and the holes 24 and 2B are circular with a diameter larger than the diameter of the round pipe.

In the embodiment, a tow hitch was used as the tow coupler 19, but a rope may also be used, or a rod with both ends ball-supported to the tow fitting and the accumulation ship, or a rod divided into a plurality of pieces and connected to each other with a universal joint. It can be anything.

During the reaping and tying work, as shown in FIG. 9, the culm M is placed on the upper surface 6a of the transmission case of the tying device 6, and the culm M located in the tying reservoir is tied and then moved to the release arm 6b. The stock is then placed on the accumulation ship 10 which is blown laterally by the action of the stock discharging rod 6C.

At this time, the tip part Ma of the tied shell culm M on the accumulation ship 10 is tilted with the tip part Ma supported by the auxiliary frame 38, and the tip part M is tilted as shown in FIG.
The tip of a is sufficiently far away from the field.

In addition, the locus of movement of the release arm 6b of the binding device 6 is selected so that the binding culm M is released diagonally backward, and the aircraft moves while the binding culm M is released diagonally backward.
Transferred laterally in a vertical position with the tip side facing backwards, and the stacking vessel 1
0. Send the bound culm M upward (see Figure 10).

In this way, as the reaping and tying machine A advances, the bound culm M is placed on the accumulating vessel 10, and the towing fitting 15, which advances integrally with the reaping and tying machine A, moves the accumulating vessel 10 through the towing coupler 19. It is towed and progresses.

At this time, since the towing coupler 19 can freely move laterally and vertically, the accumulator 10 slides on the field while being free to pitch and roll.

There is a risk that the stacker 10 will collide with an obstacle on the field or a ridge when turning the aircraft, causing damage.
Accumulating vessel 1 by removing obstacles or touching ridges etc. in advance of 0.
act as a bumper against 0 and protect the accumulation ship 10.

When loading the bundled culms M onto the accumulation ship 10, when the collection of the bundled culms M starts, the collection ship 10 is placed in the forward position as shown in FIG. ,
After that, at the intermediate position in Figure 11, Accumulator 1 in Figure 11 C.
0 rear position, and the loading position of the bundled shell culms M is gradually changed from the rear of the accumulation ship 10 to the front, and the bundled shell culms M are loaded almost uniformly on the accumulation ship 10.

That is, after releasing the locking device 30, the operator can set the stacking vessel 10 in the forward position shown in FIG.
In order to retreat to the intermediate position or the rear position shown in FIG.

When the above-mentioned stacking ship 10 retreats, the holes 24 and 2B of the support plates 23 and 27 of the support fittings C and C' are loosely engaged with the vertical rod part 16 and can move vertically and horizontally. ship 1
The support plate 23.27 is caused by the vertical vibration of the traction fitting 15 due to the vertical movement of 0, the running of the reaping machine A, and the vibration of the engine.
As a result of the vertical movement, the vertical rod portion 16 vibrates and automatically gradually retreats.

Further, even when the reaping machine A is moved forward and the accumulation ship 10 is relatively retreated, the vertical rod portion 16 is connected to the support plate 23.
．． 27 and the traction fitting 15 is engaged with the reaping machine A.
The towing fitting 15 does not move forward together with the harvesting vessel 10, and the towing fitting 15 remains at the same position together with the accumulating vessel 10, and is in a backward position with respect to the reaping machine A.

Therefore, the relative retreating operation of the accumulation ship 10 is performed easily and smoothly.

In addition, as shown in the embodiment, the vertical rod part 16 of the traction fitting 15 is made of a round bar or round pipe and has a circular cross section, and the support plate 27 and the holes 28 and 24 of the support plate 23 act as part of the support fittings C and C'.
Assuming that is circular, the vertical rod portion 16 smoothly moves in the front and back direction relative to the support fittings C and C', and the contact between the vertical rod portion 16 and the support fitting 15 when changing the loading position described above becomes surface contact. , the vertical rod portion 16 can slide more smoothly.

In addition, the hook 1 in the traction support part 17 of the traction fitting 15
Since the position 8 is laterally away from the vertical rod portion 16, the towing load is applied to the hook 18 and the towing load is applied to the cargo ship 10 being towed via the towing coupler 19 attached to the hook 18.
6, there is a risk that the vertical rod portion (round pipe) 16 may be twisted and twisted, but due to surface contact between the vertical rod portion 16 and the support fittings C and C', there is no biting and the vertical rod portion 16 always rotates and slides smoothly.

When starting the reaping work, if hollowing work is required, the stopper pin 29 is removed and the vertical rod part 16 is pushed forward, so that the support fitting c' of the reaping binding machine A,
From the support plate 23.27 of c' to the vertical rod part 1 of the traction fitting 15
6 is removed, all of the shell culm accumulating device B including the vertical rod part 16 is separated from the side of the reaping and tying machine A, the protrusion on the side of the reaping and tying machine A is eliminated, and hollowing work is made possible.

In the above-mentioned embodiment, a case where the present invention is applied to a reaping and tying machine has been described. However, in the reaper, an appropriate reaped husk conveying device for transporting unbound reaped husk culm to the upper side of a collection vessel is used. It is intended to provide

As described above, the present invention provides a system in which the support rod of the traction fitting and the support plate for slidably supporting the support rod are in a loose state, and the locking device and the support rod of the traction fitting are in an loose state. Since the elastic force is fixed, the support fitting and the locking device support the support rod of the traction fitting in a loose elastic state, and the locked state is automatically achieved by vibration in the longitudinal direction of the support rod that is greater than the spring load of the locking device. No special operations are required as the reaping machine moves forward, based on the longitudinal vibration shock of the support rod of the tow fitting caused by the vibrations of the accumulating vessel and the vibration of the engine of the reaping machine. Then, the towing metal fittings are moved backward relative to the reaping machine, and the stacking vessel can be sequentially moved to the rear position.
