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 ridges, and covers the mulch film with soil on the ridges. It is.

When performing ridge forming and film laying at the same time in this way, the wheels 1a and 1b of the traction machine have already been laid in the previous process, as shown in the schematic rear view of the work in Figure 1. Already installed multi-film
In order to avoid stepping on C ₀ , the supporting 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 towing machine. Therefore, in the next step in FIG. 1, that is, the step of forming ridges and laying the film on the left side of the figure, the center
It is necessary to shift the support position to the left. If the soil is lifted from the ground surface using power and covered with the multi-film in the ridges at the same time as the laying, the manual covering work can be omitted and efficiency is improved.

Therefore, in the present invention, in a multi-film laying device that includes a tilling device, a ridge setting device behind the tilling device, and a film laying section that lays a mulch film on the ridges formed by the ridge setting device, The soil distributing section that distributes the lifted soil on the multi-film near the ridges and the above-mentioned film laying section of the soil lifting device that lifts soil from the ground are combined into one, and both of these combined parts are connected to the soil lifting device. On the other hand, as the structure is installed so that the left and right positions can be adjusted, the laying of the multi-film and the soil covering work are always carried out automatically in the predetermined ridges.Furthermore, it is possible to automatically lay the multi-film in the predetermined ridges and cover it with soil. It has been devised so that the left and right position adjustment operations of both the soil distribution section and the earth distribution section can be easily performed in one unit. To explain the specific structure based on the drawings, as shown in the side view in Fig. 2 and the rear view in Fig. 3, the plowing depth is increased by the working machine lifting mechanism 5 of the traction machine 4.

Then, the upper parts of the gutter-shaped chute 30a, 30b, and 30c are fixed to the mounting plate 31 so that the lower parts are separated from each other, and the mounting plate 31 is attached to the soil receptacle 32 in the front view using a long pin 33 in the horizontal direction. Pivotally connected at 32
The upper edges of the respective chute 30a are roughly aligned with the bottom plate 32a of the chutes 30a, and a hopper 34 having a shape in plan view and having a shutter 33' at the lower end opening is attached to the lower part of each chute 30a. A seat 21c is provided at the lower part of the soil discharge port 21b in the upper part of the soil tray, and these chute 30a... are rotated in the left-right direction around a fulcrum pin 35 inserted through the seat 31b of the soil receiver 32 and the seat 21c of the cylinder body 21. The seat 32b is attached to one of the pin holes 21d, 21e, etc. provided in the seat 21c on an arc centered on the fulcrum pin 35
These chute pins 3 are aligned with the pin holes of , and the locking pins 36 are inserted into both of these pin holes, so that the respective hoppers 34 are positioned above the ridge grooves 13 respectively.
A soil distribution section 37 consisting of 0a... and hoppers 34 is set on the cylinder 21, and the soil distribution section 37 is pulled forward by the spring 38 until the mounting plate 31 hits the stopper 39 provided on the cylinder 21. The soil distributing section 37 can be rotated forward until it comes into contact with the earth. A vertical rod 41 is inserted into a seat 40 provided on the central chute 30b so as to be vertically movable, and the vertical rod 41 is fixed with a bolt 42, and the support frame 43a, which rotatably supports the film roll 43, is attached to the vertical rod. The arm 45 of the suppression wheel 44, which is equipped with a soft synthetic resin tire, is attached to the lower part of the vertical rod 41 so that the horizontal position can be adjusted freely, and the arm 45 of the suppression wheel 44, which is equipped with a soft synthetic resin tire, is attached to the vertical rod 41 so that the horizontal position can be adjusted _freely. Pressure wheels 44 roll on top of the multi-film C, which is pulled out from the film roll 43 and coated on the ridges A, _A0 and the ridges B, _B0 . A film laying portion 46 is pressed into the ridges B and _B0 by a pressing ring 44. Further, the shutter 33' is pivotally connected to the rear portions of the left and right side plates of the hopper 34 by a shaft 47, and the shutter 33', which is biased by a spring 48 and closes the lower end opening of the hopper 34, is capable of removing a predetermined weight of soil. When soil accumulates in the hopper 34, it opens to release the soil, and when the release is finished, the lower end opening is closed by the spring 48. Then, the ridge making and film laying work is done in the third stage.
As shown in the figure, the ridge A ₀ has already been formed in the previous process.
The ridge erecting device 12c is located at the position closest to the furrow groove B ₀ of The wheel 1a is set to be located in front of the ridge maker 12a on the left end, and the multi-film C is placed in the preformed ridge A ₀ and the ridge grooves B ₀ and B ₀ on its left and right sides.
Then, use the ridge standers 12a and 12b so that the ridge A formed in this process and the ridge grooves B on the left and right sides of the ridge A are covered.
..., the film roll 43 is set, and the right end hopper 34 is located at the left end of the multi-film C ₀ laid in the previous process and the right end of the multi-film C laid in the current process, respectively. furrow
Looking above B ₀ , hopper 34 on the left end

Then, in the process of turning back the process shown in Fig. 3 at the edge of the field and returning to the adjacent land, the mounting positions of the cylinder 21 and soil distribution part 37 are moved from the positions shown in Fig. 3 as shown in Fig. 5. When the traction machine 4 moves to the left in FIG. 2 and the tilling blade 6a of the tilling device 6 rotates, the ridge setting device 12a,
The ridges A... and the ridges B... are formed by the ridges 12b and 12c, and the left and right side plates of the central ridge erector 12b are formed.
The soil flowing between b ₁ and b ₂ is taken into the lower part of the cylinder 21 from the soil intake port 21a located at the bottom of the cylinder 21, and is lifted up inside the cylinder 21 by the auger 22. The soil is discharged from the upper soil outlet 21b to the soil receiver 32, and the soil receiver 32 is disposed at the upper part of the chute 30a, 30b...
When the soil falls down and accumulates in each hopper 34 from the chute 30a and reaches a predetermined weight, the soil is released into the mulch in the ridges and grooves B by opening the shutter 33' while keeping it in a compact shape. It is distributed on top of film C. And the ridge maker 12
Ceiling panels a ₁ , b ₄ , provided at a, 12b..., respectively
The upper surface of the ridge A is formed by b ₅ and c ₁ , and the rear plate b ₃ provided on the central ridge maker 12b removes soil from behind the left and right side plates b ₁ and b ₂ . The soil is prevented from collapsing into the ridges B, and the ridges B are formed without soil collapse.

Note that the soil lifting device 24 may use, for example, a bucket conveyor instead of the auger 22.

As described above, the mulch film laying device according to the present invention distributes the soil lifted by the soil lifting device 24, which lifts soil from the rear of the tilling device 6, onto the mulch film C near the furrows B and _B0 . The earth distribution section 37 and the film laying section 46 are combined into one body, and the combined earth distribution section 37 and film laying section 46 are connected to the soil lifting device 2.
4, the traction machine 24 can be moved to the left or _right with respect to the body of the traction machine 4. 4, the multi-film C can always be laid on the ridges A, A ₀ and the ridges B, B ₀ to be covered, and the ridges B,
B ₀ can be covered with soil, and moreover, the left and right position adjustment operations of the film laying section 46 and the soil distribution section 37, which must be performed each time the reciprocating process of laying work, are performed together, so the operation is easy. This made the process easier.
