Description

[Detailed description of the invention] This invention relates to a mulch film support device used when pouring soil or spraying fertilizer or herbicide while sequentially lifting the side edges of the mulch film that has already covered the ridges along the direction of travel. It is.

For example, when lifting mulch film and placing it in soil, leave one side of the mulch film buried in the soil.
The other side is held up by a pair of upper and lower rolls, and as it progresses, the mulch film is removed by a cultivator, etc., but tension is generated in the lifted part of the mulch film, which acts toward the center of the ridge, and the mulch film rolls. Easy to fall off.

They are particularly likely to come off when wind forces act in the same direction.

The purpose of this invention is to develop a multi-film support device that can overcome the above-mentioned drawbacks.

This idea involves installing a frame that is towed by a mobile agricultural machine, and rotatably installing rolls on both sides of this frame that flip up the inner edge of the mulch film that covers the ridges and sandwich the top and bottom of the mulch film. The drive unit of the mobile agricultural machine is connected to the roll, and the guide, which is located forward in the traveling direction of the roll and is joined to the lower inner surface of the mulch film, has an axis that is expanded downward in a V-shape when viewed from the rear. It is characterized by the fact that it has been provided.

In other words, the mulch film is pulled toward the outside of the ridge by a guide at the front in the direction of travel, thereby preventing the mulch film from coming off the roll, and ensuring that the mulch film is turned up for soil filling and other work. The mulch film is designed to facilitate this process and prevent the mulch film from loosening during re-covering.

An embodiment of this invention will be explained based on the drawings.

Reference numeral 1 denotes a horizontally long frame, and a mounting tube 2 is fixedly provided in the center of the frame 1.

Furthermore, a horizontally long shaft 3 is rotatably held in the frame 1.

A sprocket wheel (not shown) is fitted and fixed to the shaft 3 while being covered by a cover 4.

Rolls 5 are connected to both ends of the shaft 3 so as to be prevented from rotating in the rotational direction and to be slidable and fixed at arbitrary positions in the axial direction in accordance with the spacing between the ridges.

Further, on both sides of the frame 1, rolls 6 which are elastically joined to the rolls 5 are rotatably held with their axes forming a V-shape in the direction of travel.

The facing distance between these rolls 6 can also be varied in the same way as the rolls 5.

Thus, the pipes 7 are fixed with their axes perpendicular to both sides of the frame 1, and these pipes 7 have support rods 8 that extend forward in the direction of movement and are rotatable left and right and axially (up and down). It is slidably held by bolts 9 and fixed at any position.

A guide roller 10 serving as a guide is rotatably held on these support rods 8 with an axis that forms a V-shape when viewed from the rear.

In such a configuration, as shown in FIG.
The frame 1 is connected to the mobile agricultural machine 11 by tightening or other means.

Next, a sprocket wheel (not shown) provided on the axle 15 of the mobile agricultural machine 11 and a sprocket wheel provided within the cover 4 of the frame 1 are connected by a chain 16.

Then, the center of the mobile agricultural machine 11 is aligned with the center between the ridges 17, and while the inner edge of the mulch film 18 is held between the rolls 5 and 6, the machine moves backward toward the left in FIG.

As a result, the mulch film 18 is sequentially turned up along the direction of travel, and in this process, the mulch film 18 is inserted into the soil by the interpolation rotary 12.

At this time, the portion of the mulch film 18 held between the rolls 5 and 6 is pulled toward the center of the ridge 17, but the guide roller 10 is applied to the lower inner surface of the mulch film 18 in front of the rolls 5 and 6 in the traveling direction. Because of the elastic contact, the mulch film 18 does not come off the rolls 5 and 6.

As a result, the mulch film 18 can be lifted up in good condition, and soil, fertilizer, herbicide, etc. can be reliably poured into it.

The re-covered mulch film 18 also does not become loose.

Since this device is constructed as described above, the inner edge of the mulch film is lifted up sequentially along the traveling direction by the roll, and the mulch film is pulled to the outside of the ridge by a guide provided in front of the mulch film and removed from the roll. It is possible to prevent the mulch film from coming off, and therefore, it has the effect of ensuring that the mulch film can be turned up, making it easier to perform soil pouring, etc., and also preventing the mulch film from loosening when re-covering. It is something.
