Description

[Detailed description of the invention] This invention relates to the laying width of mulch film.

In order to perforate the laid mulch film, a rolling wheel with appropriate protrusions on the outer periphery of the rolling wheel rim is rolled along the ridge direction over the ridge, and the protrusions penetrate the film. When the protrusions try to come off the film, there are drawbacks such as the protrusions catching the film and tearing it, or causing the film to be wound around the wheels.

The present invention takes the following technical measures to eliminate such drawbacks. That is, a perforation protrusion (4) is provided on the outer periphery of the rim (1) to press against the mulch film (2) and perforate (3).
) is buried in an elastic body (5) up to the tip, and when the multi-film (2) is connected and perforated, the elastic body (5) is compressed to expose the perforation protrusion (4). The width of the mulch film to be laid will be the same.

With this configuration, the present invention has the following technical effects.

When the wheel rolls on the ridge film (2).

When the elastic body (5) on the outer periphery of the rolling wheel comes into contact with the film (2), it is pressed and begins to dent, and the needle-like protrusions (4) are gradually exposed and break through the film (2), forming a hole (3), and as the film (2) rolls, the elastic body (5) begins to dent. The protrusion (4) begins to be pulled out from the film (2), but at this time the elastic body (5) returns to its original position from the part where it is moving away from the film (2) and covers the protrusion (4), i.e. , the elastic body (5) presses the film (2) while the protrusion (4) begins to make a hole in the film (2) and comes out of the hole. protrusion(
4) eliminates the drawbacks such as getting caught and breaking. In addition, the elastic body (5
) and by burying the protrusion (4), there is no soil adhesion.

In the illustrated example, the roll winding fi Jl/4 (6
) A guide roll (8) for the film (6) is provided at the rear end of the support rod (7), and below this roll (8), two forming guides (9) (9) are provided along the ridge shape. This guide (9) (9) connected to the tractor is connected to the upper connecting rod (10).
) are each connected to the support members (11) (11), and on the rear side of the forming guides (9) (9), there is a film pressing ring (12) that is grounded on two grooves, that is, two series of grooves. has
Support rods (13) each bearing this pressing ring (12)
is connected to the connecting rod (10), but the pressing ring (12
), the left and right pressing wheels (12) (12) on both sides have soil-covering discs (14) that are brought close to the rear outside of the left and right pressing wheels (12) (+2) and are inclined to open in the direction of travel. (
14), and support rods (14) each supporting the disk (14)
15) (+5) respectively connect the press ring (12) to the support rod (13). In addition, on the rear side of the central pressing ring (12), several protrusions (4) are radially planted on the rim outer periphery (1), and the rim outer periphery (1) is set with the tips of these protrusions (4) as the outer periphery. A laying width (16) covered by an elastic body (5) is provided, and this laying width (1B) is connected to the rear end of the connecting rod (10) by a rear support rod (17) that supports the shaft. First, the starting end of the roll film (6) is pressed by the central and left and right press wheels (12), and as the tractor travels, the roll film (6) is pushed onto the guide roll (8). The ridge surface is coated along the ridge shape by the left and right forming guides (9) (9), and is pressed by the pressing rings (12) in the groove between the ridges and the left and right outer grooves of the two ridges. The upper surfaces of the left and right outer groove portions are covered with the soil covering disk (14) (
14), and the groove between the two furrows has the above-mentioned laying width (
18), the perforation (3) is fired. This perforation (3)
This prevents rainwater from pooling on the mulch film (2), and also prevents heavy soil, etc. from flowing out on the ridge and groove mulch film (2) on sloped areas. It is also possible to exclude the center pressing ring (12) and use only the laying width (18) for pressing.
Furthermore, set the left and right pressing wheels (+2) (+2) to a width of (16
)(16) may be substituted.
