Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mulch film peeling device, which is used to peel a used mulch film laid on the ridges of a field from the ridges after use. .

The conventional technique disclosed in Japanese Patent Application Laid-open No. 62-205728 discloses a mulch film peeling device that excavates the buried soil part of the hem along the left and right edges of the mulch film. A hem moat body is provided to pull out the hem of the mulch film from the soil.

Problems to be Solved by the Invention The hem excavation body as described above is simply for digging out the left and right hem portions of the mulch film from the soil, and the purpose is to easily pull out the hem portions from the soil. .

The soil at the foot of the ridge is dug up and the ridge slope covered with the mulch film is left as it is. This results in refilling, making it difficult to maintain smooth peeling of the mulch film.

The object of the present invention is to eliminate such defects and to enable smooth peeling of the mulch film.

Means for Solving the Problems The present invention has taken the following technical means to solve the above problems. That is, it has a plow board that plows up the covered ridges of the mulch film to a predetermined depth over the ridge width, and a film take-up reel that winds up the mulch film plowed up by the plow board. The structure of the multi-film peeling device is as follows.

The ridge on which the working mulch film has been laid is moved forward while being plowed up to an appropriate depth with a plow-up, and the mulch film peeled off from the top surface of the ridge by the plow-up is wound up with a take-up reel. In the case of the ridge soil that is plowed up in this way, the entire ridge soil is raked up together with the mulch film covering the surface, so the separation between the mulch film and the ridge soil is smooth. It is less likely that the left and right skirts of the mulch film will be backfilled with plow-raised soil, and at the same time as the mulch film is peeled off, the entire width of the ridge is once plowed up by the plow-raiser, causing swelling. be made soft.

Embodiment Next, an embodiment of the present invention will be described based on the drawings. The plow erector 1 has a vertical side plate 3 integrally formed at both ends of a left and right horizontal blade plate 2 which is wider than the width of the ridge A.
The upper sides are connected by a horizontal frame 4 extending from side to side, and the center part of this horizontal frame 4 is connected to a lower link 5 at the rear of the tractor.
The structure is such that it is towed by a connecting frame 6. The blade plate 2 is installed so that the central part of the left and right width is the apex, and the left and right end parts are inclined so as to recede, and a forward downward plowing angle B is provided. Further, the connecting frame 6 is connected to a connecting rod 7 connected between the left and right lower links 5 so as to be able to roll freely.

Further, at the rear end of the connecting frame 6, a disc cutter 9 which is rotatable around a shaft 8 and can be freely adjusted up and down with a bracket 4 is provided so as to face the center of the width of the blade plate 2. The mulch film 10 to be covered is cut and separated at the center of the left and right width.

Behind this disc cutter 9, a pair of left and right take-up reels 11 are provided on the connection frame 6, and the multi-film lO cut and separated into left and right sides by this cutter 9 is wound up, respectively. The take-up reel 11 is rotatable around a reel shaft 12, and has spikes 5 protruding from the outer periphery of the reel butt 13 to ensure reliable winding of the multi-film.

Note that the winding wheel 11 may be constructed so that it can be automatically wound by power from the tractor side, or it may be constructed so that it is driven and rotated by contact with the ridge A surface of the motorbike 5, etc. In this case, The winding wheel 11 may be vertically movable so as to be in constant contact with the surface of the ridge A.

When the mulch film 10 is coated on the ridge A side,
In the grooves C of both the left and right skirts, a weight of soil is placed on the upper surface to prevent peeling to stabilize the laying.

When peeling off the mulch film 10 from the upper side of the ridge A, the mulch film 10 is peeled off from the upper surface of the ridge A by a plow 1 pulled by a tractor.
The ridge A that is plowed and raised by this plowing and raising 1, which plows and raises the entire width at an appropriate depth, is because the ridge soil is swollen and broken down and is once floated appropriately.

The gap with the mulch film 10 covering the surface is loosened, and the weighted soil on both the left and right skirts is also removed to the outside.

In this way, as the ridges A of the plow-cutting 1 are raised, the disc cutter 9 is pressed against the upper surface of the mulch film from above, and the multi-film is cut and separated from the left and right center portions. The multi-films 10 separated in this way are each wound on a take-up reel 11.

Effects of the Invention Since the present invention has the above-mentioned configuration,
It has the following technical effects. In other words, plowing involves winding up the mulch film with a take-up reel while simultaneously plowing up the mulch film over the entire width of the ridge where the mulch film is laid. It is rare for soil to be placed on top of the mulch film again, and even if there is soil placed on the left and right hems of the mulch film as a weight, this soil cannot be placed on the outside from the top of the mulch film. The mulch film can be removed smoothly, and the mulch film can be removed smoothly, and at the same time, the entire width of the ridge can be plowed up, increasing the efficiency of the plowing work.
