Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a mulch film laying device for laying a mulch film on soil ridges in a field.

Prior art and problems to be solved by the invention As a method of laying a mulch film on the soil surface and fixing the mulch film so that it does not peel off from the soil surface,
Insert a part of this mulch film, such as the left and right sides or the center, into a buried groove formed on the soil surface, and press the buried groove in which this mulch film is inserted with a compression ring to crush it. There is a method of fixing the film, but in this laying method, the mulch film is pulled out to the soil surface from the mulch film reel that stores it, depending on the position of the suppression wheel that suppresses it from the top of the mulch film, the mode of suppression, etc. In many cases, the mulch film in the middle of the process is deviated to one side of the soil ridge surface and deviates from side to side, making it impossible to install it accurately.

The present invention aims to eliminate such defects and allow the mulch film to be pulled out accurately at the laying position.

Means to solve problems To this end, the present invention takes the following technical measures.

That is, in a mulch film laying device that embeds and fixes the central part of a mulch film in a burying groove formed on the soil surface, the guide rod that guides the mulch film from the film reel is connected to the mulch film's embedded groove. The multi-film laying device has a configuration in which a pressure ring for pressing and crushing and fixing one side of the embedding groove is provided in an inclined state with the side provided on the rear side and lower side.

While moving the working machine, the mulch film is drawn out and laid on the soil ridge surface. When the mulch film is pulled out from the film reel onto the soil surface, it is guided by the guide rod, and the center and left and right end portions of the mulch film are embedded in grooves formed on the soil surface. Press the soil on the sides of the buried trench with a compression wheel to crush and fix the buried trench.

When the mulch film pulled out from such a film reel is guided by the guide rod and pulled out, the pressing action of the pressing ring that first presses the center of the mulch film causes the direction of the crushing of the soil buried trench to be However, since the guide rod is tilted backward and downward on the pulling side of the mulch film, the center of the mulch film is The pressure side that presses the part becomes loose, and the opposite side becomes the tension side, so the mulch film cannot escape to the tension side, and the mulch film on the loose side is pushed into the embedding groove and fixed in the embedding. can do.

Example Embodiments of the present invention will be described below based on the drawings.

Vertical frames 2 are attached to the left and right sides and the center of a horizontal frame 1 connected to the rear of the tractor, and each of these vertical frames 2 is equipped with disk-shaped pushing shafts 3 to 5 and a suppressing wheel 6.

Further, a lower frame 9 is provided along the lower side of the vertical frame 2 from the horizontal frame 1, and groove cutters 10 to 12 are provided on this lower frame 9, respectively. Immediately below the horizontal frame 1, left and right cultivators 13 and a central cultivator 14 are provided, and the base of each vertical frame 2 has a film extending in the horizontal direction within a curved portion 15 that curves upward in a U-shape. The reel 16 is rotatable and the lateral end is supported. A guide rod 18 extending from the left and right ends of the horizontal frame 1 is attached by an arm 17.

The soil cultivator 13.14 is set to form a ridge A of an appropriate width and a number of grooves B on the horizontal frame l, and grooves C are formed in the center and on both left and right sides to form parallel ridges. The configuration is such that A is formed.

The groove cutters 10 to 12 form buried grooves E and F of appropriate depths at the lateral ends of the grooves B and C, and at the bottom of the ridge A. On the other hand, the groove cutter 12 is provided at the front, and these groove cutters 1112 are provided so as to form a buried groove F at both left and right sides of the groove B in the center. The groove cutters IO on both the left and right sides are formed at the bottom of the ridge A.

The guide rod 18 consists of a rotatable roll bar, and is tilted so that the left end is located at the upper front part and the right end is located at the lower rear part, and rolls onto the film reel 16 that is attached to the horizontal beam at the front upper part. The upper surface of the mulch film 20, which is rolled up and installed, is supported and guided while it is being pulled out. Further, the guide rod 18 may be configured to support and guide the lower surface of the mulch film 20. Also, this guide rod 18 is a multi-film 2
The configuration is such that the guide is guided over the width of 0-cup. Further, a guide piece 19 is provided below the guide rod 18 to guide the lower surface of the mulch film 20.

While the furrow cutter 12 at the forefront is located on the left side of the groove B in the center, the guide rod 18 is inclined so that the right end side is at the rear and lower side, and is attached to the upper surface of the ridge A. It is designed to be approached closely.

Embedded wheels 3 to 5 rotatably supported from the vertical frame 2 side are provided on the rear side of each groove cutter lO to 12, and press the mulch film 20 laid on the soil surface from the upper side. A part of this multi-film 20 is then bitten into the embedded grooves DE and F formed on each front side.

The suppression rings 6 to 8 are located on the rear side of each embedded ring 3 to 5,
The embedding grooves E and F are provided so as to compress and crush the grooves B and C diagonally downward from the center side, and are provided at the center side of each groove B and C of the embedding rings 3 to 5, Embedded grooves are provided on the rotating surface that slopes toward E and F. The mulch film 20 pushed into the trenches E and F by the embedding wheels 3 to 5 is fixed in a compressed state by the soil crushed by the compression wheels 6 to 8, and the mulch film 20 is pressed into the soil by the pressing wheels 6 to 8. Prevents it from peeling off from the surface.

The embedded shafts 3 to 5 and the compression wheels 6 to 8 are spring mechanisms 21 and 22.
It has a crane structure that moves up and down as appropriate by pressing with the button.

While the machine is moving, the multi-film 20 is pulled out from the film reel 16, passed between the guide rod 18 and the guide piece 19, and placed under each of the embedded shafts 3 to 5, the suppression wheels 6 to 8, etc. and guide the drawer to the rear. The mulch film 20 drawn out onto the soil surface in this manner has its entire width center and left and right sides located in the grooves B and C. In addition, each of the groove cutters 10 to 12 cuts an embedded groove D along both left and right edges of the grooves B and C.
E and F are formed. For this reason, when the mulch film 20 is laid on the soil surface, the upper side is pushed by the embedded shafts 3 to 5 and the compression wheels 6 to 8, and the mulch film 20 comes to follow the ridges A and the full B part between A. .

The mulch film 20 that covered the soil surface of the ridges A, B, and C in this way is placed in the embedded grooves, E, and F with the embedded shafts 3 to 5.
pushed by. The mulch film 20 is pushed into the embedded groove B by the embedded shaft 5 in the central groove B, and the right half is guided by the slope of the guide rod 18 to the center side as shown in FIG. be drawn to. The central part of the mulch film 20 pushed into the embedding groove by the embedding shaft 5 is pressed from the top surface of the film to the top surface of the groove B by the suppression ring 8, and the embedding groove is crushed. It is fixed to the soil surface as shown in the figure.

Furthermore, this multi-film 20 has an embedded shaft 3.4 on the rear side.
The pressure rings 6.7 are embedded in the embedded grooves E and F cut by the respective groove cutters 10 and 11 (Fig. 6), and in the same manner, the suppression rings 6.7
It is compressed and fixed by (Figure 7). When the mulch film 20 is pushed in by the central embedding shaft 4, the mulch film portion located in the full B portion is already fixed by the front embedding shaft 5, the compression ring 8, etc. Therefore, the mulch film 20 portion on the left side of the embedding shaft 4 is fixed, and the mulch film 20 portion on the right side is pulled.

In this way, the mulch film 20, which is embedded and fixed in the soil embedded groove F by the embedded shaft 5 and the compression ring 8 in the central part, is moved along the sloped ridge soil surface by the inclination of the guide rod 18. While receiving the same pulling pressure from the embedded groove in the center and the part pulled out and guided by the guide rod 18 on the opposite higher side in order to be pulled toward the F part side,
Since the mulch film 20 is laid down, the full width of the mulch film does not shift from side to side, and stable and accurate laying can be performed.

Effects of the Invention Since the present invention is configured as described above, it has the following technical effects. That is, when pulling out the mulch film from the film reel, in which the left and right sides and the center part of the mulch film are embedded and fixed in the embedding groove formed on the soil surface, the mulch film pulled out from the film reel is The embedding side of the mulch film is loosened by the pressure ring in the middle part, and the puller is guided by the guide rod, which is tilted so that the opposite side becomes the tension side. This makes it easy to determine the embedding position of the center part of the mulch film, and prevents it from shifting. You can maintain stable installation by reducing the amount.
