Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-film laying device that forms a plurality of ridges, simultaneously lays a mulch film in these ridges and furrows, and covers the ridges with the multi-film with soil. It is.

When performing ridge forming and film laying at the same time in this way, as shown in the schematic rear view of the work in Figure 1, the wheels 1a and 1b of the traction machine are attached to the existing material that has already been laid in the previous process. Laying multi-film
In order to avoid stepping on Co, the support position of the film roll 2 is biased to one side in the left-right direction (to the right in the figure) with respect to the center l of the body of this towing machine. The next step in Figure 1, i.e.
In the process of forming ridges and laying the film on the left side of the drawing, it is necessary to shift the supporting position of the film roll 2 to the left side with respect to the center l of the machine body. If the ridges are covered with soil at the same time as the laying, the manual covering work can be omitted, improving efficiency.

Therefore, in the present invention, the front part of the parallel link mechanism is pivotally attached to the front part of the machine frame of the multi-film laying device, so that the rear part of the parallel link mechanism can be fixed at respective positions swinging left and right in the direction of travel. The multi-film laying device attached to the above-mentioned parallel link mechanism has a soil lifting section for lifting tilled soil before the ridges have formed, and a film laying section for laying the mulch film on the plurality of ridges that have been formed. , the work of laying multi-film and covering the soil over multiple ridges can be done efficiently and without the need for human labor by using a back-and-forth process, and,
The present invention has been devised so that the positions of the soil lifting section and the film laying section for each reciprocating stroke can be changed by a single operation.

Next, to explain one embodiment of the present invention, as shown in a side view in FIG. 2 and a plan view of the main parts in FIG. The hit part of the machine frame 8 is connected to the hit part 7 of the connecting rod 6 of the rotary tilling device 5 which is connected so as to be adjustable, and the base plate 10 is fixed to the horizontal rod 9 of this machine frame 8. , front and rear holder plates 1

The central pin hole 1 is formed in the base plate 10.
0a, left and right pin holes 10b, 10c are provided, and the pin hole 11a provided in the holder plate 11 is aligned with the pin hole 10a of the base plate 10, and the pin 2 is inserted.
2, the parallel link mechanism 21 is fixed at the center position in the left-right direction of the rotary tiller 5 as shown in FIG. 3, and the left and right pin holes 10b,
10c, for example, the left pin hole 10b and the pin hole 11
When the pin 22 is inserted into a, as shown in Fig. 4,
The parallel link mechanism 21 is configured such that its rear portion is fixed in a position swung to the left. and,
Soil lifting section 23, film laying section 24, and soil distribution section 2
5 and 5 are attached to respective positions of this parallel link mechanism 21. To explain one embodiment of each structure, the soil lifting section 23 is attached to pulleys 26 and 2 on the upper and lower sides.
The frames 28, 28 on which the
3 and attach it to the belt 30 on which the lugs 29... or bucket belts are arranged,
6 and 27, the belt 30 is rotated by the hydraulic motor 31 in the direction of the arrow in FIG.
2, 32... are scooped up by the lugs 29..., the lifted soil released from the belt 30 near the upper pulley 26 is guided by the guide cover 33, and is moved to the hopper 34 of the soil distribution section 25. lead to.

The hopper 34 of the soil distribution section 25 is attached to the upper part of a support shaft 16, and this support shaft 16 is fixed to a link 17, and a mounting rod 35 is fixedly installed at the lower part of the link 17. Then, at the bottom of the hopper 34, gutter-shaped earth distribution bodies 36a, 36b,
36c... are formed in communication. The film laying device 24 includes a roll holder 37 attached to a mounting rod 35.
The film roll 38 is supported by the pressure wheel holder 39 attached to the mounting rod 35, and the pressure wheels 40 are mounted on the pressure wheel holder 39 attached to the mounting rod 35. 40... to extend the ridges A, A... and the ridges B, B....

Then, a horizontal rod 42 is fixed to the lower part of the vertical rod 41 fixed to the frame 9, and rolling wheels 43 that roll in the ridges B are mounted on the horizontal rod 42, and the multi-film is laid. The front part of the device is supported by wheels 43. A plurality of ribbed plates 32 are attached to the horizontal rods 42, and the arms 44 are attached to the ribbed plates 32 in the center of the left and right sides.
The frame 28 of the soil lifting section 23 is extended forward, and the
A rotation center shaft 46 is attached to the left and right center of the bracket 45 (directly below the fulcrum pin 15) attached to the lower part of the bracket 28.
Since the rotation center shaft 46 is fitted into the bearing portion 47 provided on the arm 44, when the parallel link mechanism 21 is rotated as described above, the belt 30 of the soil lifting portion 23 is rotated. The upper part is then swung leftward or rightward about the central axis 46, and its conveyance plane is not reversed. Further, an appropriate shutter may be provided in the hopper 34 or at the lower end of the earth distribution bodies 36a, 36b, etc., so that the soil is covered in a lump shape.

When the film laying work is carried out in the direction of the arrow in Fig. 4, the leftmost ridge plate 32 is positioned in the ridge Bo of the ridge Ao already formed in the previous step, and the traction machine The left wheel of No. 5 is located in front of the leftmost growing ridge board 32, and the right wheel is located in front of the rightmost growing ridge board 32, respectively.
, and then swing the parallel link mechanism 21 to the left and insert the pins 22 into the pin holes 10b and 11a.
The film laying part 24 is positioned so as to cover half of the ridge Ao, the ridge A formed in this process, and the ridges B and B on the left and right sides of the ridge A, and the soil distribution part 36
a, 36b, 36c extend above the furrows Bo and B, B, and the tilled soil near the front of the furrow B before the film is laid is removed by the lugs 29, 29... of the soil lifting section 23. Rake up the soil distribution body 36a,
The ridges Bo, B, B are covered with soil D from 36b, 36c.

In order to perform the return stroke in the opposite direction to that shown in FIG. When the pins 22 are aligned and inserted, the film is laid in the respective ridges Ao, A, A and the ridges Bo, B, B, as in the case of FIG. 4 described above. In order to maintain the left-right balance when traveling on the road, the soil lifting section 23, film laying section 24, and soil distributing section 25 are set at the center. Note that a soil lifting spiral may be used as the soil lifting section 23.

Since the multi-film laying device according to the present invention is configured as described in the claims, the multi-film laying device can efficiently lay multi-film over the entire surface of a field in a plurality of ridges by reciprocating work strokes. At the same time, it became possible to use the claws of the multi-film to perform soil-laying work to prevent peeling without requiring any human labor. Moreover, the earth lifting section and film laying section for each reciprocating stroke are performed in a single operation by a parallel link mechanism, making it extremely rational. In addition, by attaching the soil distribution section to the parallel link mechanism, it is not only easy to move the soil, but also the soil that presses the film is guided correctly to the valleys of the ridges.
It will be beautifully finished.
