This invention relates to a tunnel mulch work machine that can carry out a series of operations such as pressing down the hem of the film by filling it with earth in one stroke, and particularly relates to a support fall detection device that detects the fall of a tunnel support support. It is.

なかった。Conventionally, mulch film laying equipment that lays mulch film on the surface of fields that have been plowed, leveled, and ridged, and sowing that sows seeds or transplants seedlings into holes made in the mulch film that has been laid on the field. Alternatively, seedling transplanting devices are known, but the work involves pushing tunnel supports into the field and setting them up at approximately predetermined intervals, straddling the mulch film rows on which seeds or seedlings have been transplanted, and the outer circumference of tunnel supports set in the field. There has never been a working machine that can continuously carry out the mulch film covering operation in one stroke, in which the mulch film is fed out along the ground to cover it, and the bottom of the film that touches the ground is pressed down with soil.

認する必要があった。Each of the above-mentioned prior art devices is independent, and some of them are combined, but the tunnel support is pushed into the field so as to straddle the mulch film row on which seeds or seedlings have been transplanted. However, along with the development of this device, we coated the outer periphery of tunnel supports erected in the field with mulch film.
There was a desire for a work machine that could perform tunnel mulching work in one stroke by combining a device that bulges and presses the ground-contact hem of the film. In addition, since the work of pushing the tunnel supports into the field and setting them up at approximately predetermined intervals is done while the vehicle is running, make sure that the tunnel supports set in the field are standing almost vertically without falling forward or backward. There was a need.

ものである。[Means for solving the problem by IW] In order to achieve the above object, the present invention provides a tunnel support supply system in which at least a plurality of tunnel supports are loaded in an inverted U-shape onto a traveling vehicle body and are sequentially fed toward the rear. A tunnel support mechanism, a tunnel support insertion mechanism that holds the tunnel support sent out by the tunnel support supply mechanism one by one in an inverted U shape and moves it to the field, and inserts and erects the tunnel support into the field. A film laying mechanism for covering the outer periphery of an erected tunnel support with a mulch film, and a detection device for detecting when the tunnel support has fallen in the front-rear direction is provided behind the film laying mechanism. That is.
