Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a mulch film laying machine, which is used by being towed by a traveling vehicle body.

Conventional technology and problems to be solved by the invention A tilling device that plows while being towed by a traveling vehicle body.

A mulch film laying work machine that consists of a ridge forming device that forms a plurality of ridges on the plowed soil and a coating device that covers the surface of the mulch ridges with mulch film is capable of simultaneously forming multiple ridges in this way. When covering with a single mulch film, the mulch film tends to shift laterally on one side due to differences in the shape of each ridge and differences in the resistance of the soil to the mulch film, resulting in uneven coverage of the mulch film over multiple ridges. There is a risk that it will become.

Means for Solving the Problems The present invention comprises a tillage device 2 that tilles while being towed by a traveling vehicle body 1, a furrow forming device 3 that forms a plurality of furrows (A) (A) on the tillage traces, and a furrow forming device 3 that forms a plurality of furrows (A) (A) on the tillage marks. In a mulch film laying work machine consisting of a coating device 5 that covers the surface of the ridge (A) and (A) with a single mulch film 4, the mulch film is paid out from a film roll (4a) located above the coating device 5. The center portion of the mulch film 4 in the left and right direction is connected to the ridge (A) (
b) An appropriate number of protrusions 7, 7 are provided on the guide roller 6 that presses and guides the interstitial bottom (b) to pierce the mulch film 4 as the guide roller 6 rotates and prevent the mulch film 4 from moving laterally. A mulch film laying work machine is characterized in that:

Effect of the Invention A plurality of ridges (A) (A) are formed by the ridge forming device 3 on the plowed area plowed by the tillage device 2 pulled by the traveling vehicle body 1, and the surface of these multiple ridges (A) (A) The single mulch film 4 that covers
4a), the center part in the left and right direction is pressed and guided by the guide roller 6 to the bottom part (b) between the two ridges (a) and (a), and is pierced by the protrusions 7, 7 of the guide roller 6, so that the lateral It is laid on the surface of multiple ridges (a) and ridge bottoms (b) while being prevented from moving.

Effects of the Invention Because the mulch film 4 in the middle of being laid is prevented from moving laterally by the action of the protrusions 7, 7 of the guide roller 6, it is difficult to shift to one side with respect to the plurality of ridges (A) and (A). Therefore, the state of covering the mulch film 4 on the plurality of ridges (A) and (A) can be made uniform.
