The swing arm 46, which was held in the ascending position U, is moved to the descending position D indicated by the chain line by the urging force of the spring 49, and the seat supporting rod 47 is laid on the laying side seat.
The feeding end portion of the sheet 30a that is cut from 30b and remains below the pressing roller 35 is pressed and supported by the pressing roller 35.

With the seat 30a being supported, the machine body K is swung to move to the next return stroke, and then the parallel link mechanism 1 and the roll sheet feeding section 40 are lowered. The swing arm 46 at the position D is pulled by the Bowden wire 53 and moves to the raised position U. As a result, the feeding side sheet 30a by the sheet supporting rod 47
Although the support of the end portion is released, in this case, the feeding end portion of the sheet 30a is located below the pressing roller 35 and is pressed against the surface of the field H. Therefore, the sheet 30a fed out as the machine body K advances It can be attached to the H surface and automatically delivered.

Further, although not shown, the switching control of the clutch lever 13 and the hydraulic expansion / contraction mechanism is performed so that the parallel link mechanism 1 moves up when the clutch lever 13 moves to the cutting position, and moves down when the clutch lever 13 moves to the entry position. The electromagnetic switching valve may be interlocked and connected by an electric circuit.

In this way, when the parallel link mechanism 1 is raised to move or turn the machine body K, the seeder 5 and the roll sheet feeding unit
40 is lifted up and cut from the laying side sheet 30b, and the end of the feeding side sheet 30a remaining below the pressing roller 35 is supported by the support mechanism 50, so that it is swung around by wind or movement of the machine body K or the like. The sheet 30a on the delivery side is not disturbed even when it is tilted, and the delivery in the next process can be performed extremely smoothly.

Further, the support mechanism 50 can automatically support or release the end portion of the feeding side sheet 30a below the pressing roller 35 in association with the elevation of the parallel link accompanying the turning of the machine body K.

Further, at the end of the work of the laying process, the pressing roller is pressed by the cutting blade 55 which operates in conjunction with the movement of the cutting position of the clutch lever 13.
If the end portion of the feeding-side sheet 30a is cut behind 35, the manual cutting work at the end of the work for each article can be eliminated, and the left and right sides of the laying-side sheet 30b are It can be embedded at the same time as the laying work by the embedded wheel 35a.

Although the multi-sheet for laying a sheet in the field is described above, the roll-sheet feeding device of the present invention is a roll-sheet feeding device for a tunnel mulch that includes a pressing roller that feeds the sheet while rolling it into the field. Also available for.

[Effect of device]

As described above, according to the present invention, the sheet feeding unit connected to the rear of the towing and moving body is provided so as to be able to move up and down, and the sheet feeding unit pushes out the sheet from the roll sheet while rolling it in the field scene. Even in the case where a roller is provided, a support means for pressing and supporting the feeding side sheet extending below the pressing roller is provided opposite to the pressing roller, and the feeding side is provided only when the sheet feeding portion is lifted up by the supporting means. Since the sheet can be supported, the sheet on the delivery side will not be disturbed even if it is subjected to a tilt due to the wind or a swing that is swung around when the machine is moving or turning, and it is easy to start feeding the sheet to the next process and work efficiency is improved. Can be improved.

Therefore, as in the past, the roll-side feed side sheet is disturbed due to wind-induced swinging or swinging around when the machine is moving / turning, making it difficult to feed the roll sheet to the next process and reducing work efficiency. The problem can be solved.
