The shaft portion is provided with a drive mechanism capable of supporting the winding roll and rotating it in reverse.

In a tunnel mulch installation/removal device with such a configuration, first, when performing tunnel mulch installation work, the ground is plowed and ridged in advance, a mulch film is laid down, and seeds are sown or seedlings are transplanted into the holes of the film. The traveling vehicle body 1 is positioned so as to straddle the mulched cultivation ridge, and the traveling vehicle body 1 is caused to travel in the direction of the forward arrow in FIG. 1 at approximately a predetermined speed. Then, the tunnel struts 6 loaded onto the conveyor 5 in the tunnel strut supply mechanism 4 are sent out one by one from the conveyance end and supplied to the clamp section 17 of the tunnel strut insertion machine 1i17 at position A.

Furthermore, since the clamp part !7 is three-dimensionally inclined at an angle γ in the direction perpendicular to the endless check 714, the tunnel support 6 is held in an almost vertical state by the clamp part 17 and is tilted. It can be moved downward and inserted into the field F almost vertically, and even if the tunnel support 6 is opened downward (usually about 15 degrees to the vertical plane) due to the angles β and γ. , it can be inserted securely.

Then, tunnel supports 6 are erected at predetermined intervals in the field F.

The tunnel support insertion mechanism 7, film laying mechanism 25, etc. are moved backwards to correspond to the ridge end of the tunnel multi-ridge to be removed. Then, the end portion of the mulch film 28a is wound around a take-up roll that is mounted on the shaft from which the mulch film roll 28 has been removed, and the work is started. The hem of the mulch film 28a is pressed down with soil from the field when it is laid, but since the hem is opened for temperature control 9 ventilation during crop cultivation, there is not much soil covered, and the top layer is not covered. is removed by the disk 32, or by simply winding it up with a take-up roll, and the multi-film 28a is wound up.

At this time, depending on the state of the tunnel mulch, the left and right pressing rolls 31, 31°, upper disk 32, etc. may be removed.

On the other hand, in the tunnel support insertion mechanism 7, the endless chino 14
rotates in the direction indicated by the arrow in FIG. 2 (clamp portion 17 rises on the inside), and the clamp portion 17 with the rotation clamp 20 opened by the torsion spring 22 rotates together. Then, as the aircraft moves, the clamp part 17 moves to the first position.
When reaching position B in the figure, the base of the tunnel support 60 standing in the field is located between the fixed clamp 18 and the rotating clamp 20, and when the clamp part 17 reaches the guide rail 24, the rotating clamp 20 The guide roller 21 contacts the guide rail 24 to close the rotary clamp 20 against the elastic force of the torsion spring 22, thereby sandwiching the tunnel support 6 between it and the fixed clamp 18. Then, as the endless chino 14 rotates, the tunnel support 6 is sequentially pulled out and raised by the clamp part 17, and when the clamp part I7 reaches the end of the guide rail 24 (position A in FIG. 1), the clamp part 17 The pinched tunnel support 6 is released, and the tunnel support 6 is supplied to the tunnel support supply mechanism 4, sent to the front side of the traveling vehicle body I by the left and right conveyors 5, and collected.

Also, when removing only the tunnel support 6 erected in the field F, the film laying mechanism 25 can be removed from the hit mechanism 26 in advance.

Further, a gauge wheel 41 is provided on the front side of the upper end of the strut clamp section 38 .

As shown in FIGS. 8 to 1, the column insertion mechanism 40 is provided with a pair of rollers 42 with protrusions and a feed roll 43 that rotate in opposition to and in contact with the lower sides of the tunnel column 6. . These protruded rolls 42 and feed rolls 43 can be moved to a position where they are in contact with the tunnel support 6 and a position where they are separated from each other, and can also rotate in the opposite direction.

Rack teeth 44 may be formed at the lower part of the tunnel support 6, and binion teeth may be provided on the outer periphery of the feed roll 43 so that they engage with each other, and engagement holes 45 or racks 46 may be provided in the plate-shaped support 6a, It may be configured to mesh with pinion teeth provided on the outer periphery of the protruded roll 42 or the feed roll 43.

Behind the tunnel support insertion mechanism 7, a film laying mechanism 25 for laying a mulch film along the outer periphery of the tunnel support 6 erected at predetermined intervals in the field F by the tunnel support insertion mechanism 7 is provided. ing. This film laying mechanism 25 has a multi-film roll 28 mounted on a frame 27 that can be attached and detached by a hitch mechanism 26 at the rear of the machine body 2, and a central pressing roll 30 that presses down when the multi-film 28a is fed out. Left and right pressing rolls 31, 31, and a disk 32 are provided as overlays for pressing down the ground hem of the multi-film 28a, which covers the outer periphery of the tunnel support 6 and whose both ends are grounded. A drive mechanism that supports the take-up roll and is capable of rotating the take-up roll in reverse is provided on the shaft part that supports the multi-film roll 28 .

In the tunnel mulch installation/removal device of the second embodiment having such a configuration, the ground is plowed and leveled with ridges in advance, and a mulch film is laid so as to straddle the mulch cultivation ridges in which seeds are sown or seedlings are transplanted into the holes of the film. The traveling vehicle body 1 is positioned at the position shown in FIG. 1, and the traveling vehicle body 1 is caused to travel in the forward direction of the arrow in FIG.

Then, the tunnel strut 6 loaded into the tunnel strut feeding cylinder mechanism 34 in the tunnel strut supply mechanism 4 is
The rods are sent out one by one from the transport end and supplied to the strut clamp section 38 of the tunnel strut insertion mechanism 7.

In the tunnel support insertion mechanism 7, the support frame 33 of the tunnel support supply mechanism 4 is pulled to the front end position of its movement range by the hydraulic cylinder, and the support link 36 and the tension spring 37 are in a contracted position, and the support frame 33 is closed at the support clamp part. The tunnel support 6 supplied to the support 38 is pushed downward by the support support hydraulic cylinder 34, and when the lower end of the tunnel support 6 reaches the support insertion mechanism 40,
Its lower end is sent downward by seven rotations of engagement between the protruded roller 42 and the feed roll 43, and is inserted into the field F to a predetermined depth, thereby completing the work of inserting the tunnel support 6. At this time, the hydraulic cylinder 39 for pushing the support column is contracted and returned to its original state, and the hydraulic cylinder that had been pulling the support frame 33 of the tunnel support supply mechanism 4 to the front end position of the movement range is released so that it can be extended, and the hydraulic cylinder 39 is expanded. As the vehicle body 1 moves, the tunnel support supply mechanism 4 and the tunnel support insertion mechanism 7 reach the rear end position of their movement range.

That is, the tunnel support supply mechanism 4 and the tunnel support insertion mechanism 7 allow the traveling vehicle body l to travel at a predetermined speed.

Even though it is moving, the tunnel support 6 is inserted into the column in a stopped state, and the work is completed.

When the pillar insertion work of the tunnel support 6 is completed, the protruded roller 42 and the feed roll 43 are immediately separated from the tunnel support 6, and from this state, the tunnel support supply mechanism 4 and the tunnel support insertion mechanism 7 are rapidly moved to the front end position of the moving range. , and the tunnel support insertion mechanism 7 starts inserting the tunnel support 6 into the field F again. By repeating these operations, continuous support work is performed. Therefore, while the machine body 2 is running, the tunnel support 6 is inserted into the field F in the same state as when the machine body 2 has stopped running, and the tunnel support 6 is almost perpendicular to the field F without wobbling. Can be erected.

Then, tunnel supports 6 are erected at predetermined intervals in the field F.
From the multi-film roll 28 to the multi-film 28a
is pressed down by the central press roll 30 and the left and right press rolls 31 and drawn out, covering the outer circumferential part of the tunnel support 6, and both ends thereof are grounded.

Then, the end of the multi-film film 28a is mounted on the shaft from which the multi-film roll 28 is removed. Wrap it around and start working. The hem of the mulch film 28a is held down by field soil when it is laid, but since the hem is opened for temperature control 9 ventilation during crop cultivation, there is not too much soil covered, and the top layer is The multi-film 28a is removed by removing it with the disk 32 or by simply winding it up with a take-up roll. At this time, depending on the condition of the tunnel mulch, the left and right pressing rolls 31 and 31, and the upper hanging disc 32
etc. may be removed.

On the other hand, in the tunnel support insertion mechanism 7, the tunnel support 6
There are rollers 4 with protrusions spaced apart on the left and right at the bottom of both sides of the
2. When the feed roll 43 faces the tunnel support 6, the protruded roller 42 and the feed roll 43 rotate in the opposite direction, thereby forming the rack teeth 44 formed at the bottom of the tunnel support 6 and the plate-shaped support 6a. The tunnel support 6 is sequentially pulled out by meshing with the meshing hole 45 or rack 46, etc.

When this extraction is started, the support frame 33 is located near the rear end of the vehicle body 1, and when the tunnel support 6 has been pulled out, the support frame 33 has moved to the front side of the vehicle body 1. Then, the tunnel support 6 that was pulled out is
It is supplied to the tunnel support supply mechanism 4, sent to the front side of the traveling vehicle body 1 by the tunnel support feed cylinder mechanism 34, and collected. At this time, the hydraulic cylinder 3 for pushing the column
There is no need to use 9.

Also, when removing only the tunnel support 6 erected in the field F, the film laying mechanism 25 can be removed from the hit mechanism 26 in advance.
Then, the traveling vehicle body 1, tunnel support insertion mechanism 7, etc. are moved backward to correspond to the ridge end of the tunnel multi-ridge to be removed. And multi film 2
