Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-work machine for coating a surface of soil in a field with a film.

[0002]

2. Description of the Related Art As shown in FIG. 9 (a), a conventional multi-working machine has a groove plate 101 and a sponge roller 10 for pedaling.
2 and the soil gathering disk 103 are known, and when the soil surface C is covered with the film D by this, as shown in FIG.
Sponge roller 1 that pulls out film D of 5 and rolls
Press the both sides of film D with 02, and lay down the disk 1
By rolling 03, the soil on both side edges is scraped and applied to the both side edges of the film D.

This type of multi-working machine is used for the purpose of keeping the soil warm and water, but in addition to this, in recent years, it is expected to be used for soil disinfection. When used for this purpose, a chemical injector is attached to the multi-working machine, and while running, the chemical is injected into the ridges after ridge formation, and the ridges are immediately covered with a film. In this case, in addition to the labor-saving effect that the chemical solution injection process and the coating process can be performed at the same time,
Since the drug solution does not diffuse to the outside air, a small amount of drug solution is required,
Moreover, there is an advantage that the risk of secondary pollution due to the diffusion of the chemical liquid is small.

[0004]

However, in the conventional multi-working machine, since the left and right soils are scraped by the soiling disk, a gap is inevitably formed between the adjacent ridges.
Therefore, when it is used for soil disinfection, there is a possibility that the chemical solution diffuses from this gap, the disinfection effect is weakened, and the surrounding environment is adversely affected. In addition, since the film is fixed by hanging it on both ends of the film, the soil applied to both ends of the film cannot be disinfected, and there is a problem that pathogenic bacteria reenter the soil from here.

In view of these problems of the conventional multi-working machine, the present invention provides a multi-working machine that can cover the soil without any gap and can fix the film without laying the soil on both ends of the film. The purpose is to provide.

[0006]

In order to solve the above problems, the present invention has the following constitution.

That is, according to the first aspect of the present invention, the left and right machine frames are respectively provided with inner surface plates whose lower ends are inclined toward the inside of the machine body.
The grooved plate, the film tension rods extending from the grooved plate toward the rear of the fuselage, and the film tension rods facing each other along the outside of the film tension rod, and the lower end inclined toward the inside of the fuselage. A disc, the left and right side edges of the film are stepped on by the inclined discs, respectively, and the left and right side edges of the film are folded below the film tension rod to form a bag-shaped portion on the film, and the bag-shaped portion. It is a multi-working machine characterized in that the soil in the film is supplied to and the film is fixed.

A second invention is the multi-working machine according to claim 1, wherein a gap through which soil is to pass is formed between the film tension rod and the groove plate .

[0009]

According to the present invention, as the machine body advances, a groove is formed on the soil surface by the groove cutting plate, and the soil is piled up in an inverted V shape . The left and right side edges of the film are pressed by the inclined discs and pulled out while slidingly contacting the film tension rod. Here, a bag-like portion is formed at the left and right ends of the film, with the film tension rod as the bottom and opening toward the inside of the body. Soil is supplied to the bag-shaped portion from the inside of the film to fix the film.

As described above, according to the present invention, the left and right side edges of the film are folded to form a bag-shaped portion, and soil is supplied and fixed from the inside of the bag-shaped portion. Therefore, unlike the conventional device, it is not necessary to lay the film on both ends. Further, since it is not necessary to scrape the soil on the left and right with the soil gathering disc, no gap is formed between the adjacent ridges and the entire surface of the soil can be covered without any gap.

When the spring 61 turns upward and the spring 61 crosses the rotation axis of the shaft 58, the traction force of the spring 61 holds the groove expansion plate N in a state of jumping up.

A work process for performing soil disinfection and multi-simultaneous work using the multi-working machine of the present invention will be described with reference to the drawings.

First, the coating process of the first row will be described. Prior to the covering step, the operator first raises the inclined disc G as shown in FIG.
The film D is unwound by hand and pulled out through the sponge rolls 18 and 19 of the tension roller K, and the inclined disk G is lowered to step the left and right ends of the film D on the inclined roll G. Start. At that time, the groove expansion plate N is swung downward in advance as shown in FIG.

Next, the coating process of the first row is started. For the work, the worker holds the handle 2 and moves backward, and the chemical liquid injector M
, While spraying the chemical solution in the soil about every 30 cm in the front-back direction.

As the body advances, the groove expansion plate N moves outward,
The inner surface plate 8 of the grooving plate F inwardly removes soil and forms grooves on the soil surfaces on both left and right sides of the machine body.

On the other hand, as the tilted disc G rolls, the film D is sequentially drawn out. The left and right ends of the film D are pulled out while slidingly contacting the tension roller K and the film tension rod 11, and then, as shown in FIG. 7A, are stepped on the inclined disc G and arranged at the bottom of the groove. . Therefore, the left and right ends of the film D are bent through the film tension rods 11, and a bag-like portion S is formed with the bent portion as a bottom and opening toward the inside of the body.

Next, as shown in FIG. 7 (b), the groove plate F
The upper surface of the soil that was collected and raised by the inner plate 8 of
The swing roller H steps on the film D. The soil on the inner side of the machine falls by its own weight through the space 12 between the tension rod 11 and the inner surface plate 8 and is pushed out by the urging force of the rocking roller H, so that the bag-shaped portion S of the film D Fall inside.

Further, as shown in FIG. 7C, the bag-like portion S of the film D is stepped on from above by the treading roller J and fixed, whereby the covering step is completed. When the coating of the first row is completed in this way, the worker appropriately cuts the film D.

In this covering step, the tension roller L at the center and the swing rollers H at the left and right keep the film D in a tension state without slackening. Also,
In the coating process, the film D tends to be strained and biased toward the center, so that the left and right ends of the film D are turned over,
As shown in FIG. 2, the tension roller K is locked to the side end of the sponge roller 19. Therefore, the film D is not biased to the center during the work.

Next, the operator moves the machine body and shifts to the coating process of the second row.

The worker performs a preparatory work prior to the coating process of the second row. Here, the end of the film D is pulled out through the space between the sponge rolls 18 and 19 of the stretching roller K, as in the case of the above-described first row covering operation.
Although the left and right ends of the first row are stepped on the inclined roll G, unlike the case of the covering step of the first row, the groove expansion plate N flips up the already covered first row side and holds it in the raised position, The uncoated groove expansion plate N on the opposite side is lowered.

In the covering process of the second row, the bag-shaped portion S of the film D of the first row is then sacked with the bags of the film D of the second row in a state where one side of the groove expansion plate N is flipped up. The procedure is similar to that for the first row above, except that care is taken to ensure that the contours are in close contact.

In the second row covering step, since the groove expanding plates N on the first row side are flipped up, the end portions of the film D of the first row already covered are not caught by the groove expanding plates N. At the same time, the soil surface can be closely contacted between the film D in the first row and the film D in the second row without exposing the soil surface to form a coating.

Further, by lowering the groove expansion plate N on the opposite side (uncoated side), a groove is formed in advance on one side of the third row to be covered next and covers the soil surface of the third row. Sometimes, since the soil has already been moved toward the inside of the machine body, the grooving plate does not remove the soil on the coated side, and thus the soil is not applied to the film D side end on the second row side.

Similarly to the case of the second row, the covering process for the third and subsequent rows is also carried out with the groove-expanding plate N on the coated side flipped up and the groove-expanding plate N on the uncoated side lowered. In this way, the soil in each row is disinfected one after another and covered with the film D. When planting a crop after disinfection, the film D is peeled off from the soil surface, cultivated and ridged, and then planted.

Next, a second embodiment of the present invention will be described.

The multi-working machine B2 of the second embodiment is intended to more surely supply the soil for fixing the both ends of the film D to the bag-shaped portion S in the multi-working machine B described above. In addition, an earth moving plate 63, an earth collecting plate 64, and the like shown below are added to the multi-working machine of the first embodiment described above.

That is, as shown in FIG. 8, a mounting rod 61 is extended near the rear end 11a of the film tension rod 11 toward the inside of the body, and the other end of the mounting rod 61 is bent backward. . At the tip of the mounting rod 61, a soil moving plate 63 having a rear end 62 projecting to the outside of the machine is fixed downward.

On the other hand, a horizontal rod 65 is laterally projected at the front end of the mounting portion 7 of the grooved plate F, and a flexible material such as spring steel is attached to the end of the horizontal rod 65. Formed earth plate 64
Secure the front end of. The rear end of the earth collecting plate 64 is a free end 65,
As shown in the drawing, it is projected obliquely toward the grooved plate F side outside the machine body.

At the front end of the inner surface plate 8 of the groove plate F, a current plate 67 is provided so as to project toward the inside of the machine body. This straightening plate 67
Is inclined so that it becomes lower from the front end toward the rear end.

The rest of the configuration and operation are the same as those of the first embodiment described above, so a description thereof will be omitted.

Thus, the multi-work machine B2 of the second embodiment is used.
When performing the covering work using, as the aircraft progresses,
While the grooving plate F forms a groove, the soil on the inner side of the machine body is regulated on the upper surface by the rectifying plate 67 and is guided by the soil collecting plate 64 to be collected in the vicinity of the grooving plate F. Next, the tilted disc G
Presses the side edge of the film D and places the side edge of the film D at the bottom of the groove. Inside the folded bag-like portion S of the film D, the soil on the inner side of the body falls. Then, the soil moving plate 63 scrapes the soil further toward the inside of the machine, and the soil is further supplied to the bag-shaped portion S inside the film D. Then, the treading roller J treads the bag-like portion S from above to complete the covering work.

By regulating the height of the soil surface in this way, the straightening vane 67 prevents excessive supply of soil and moves excess soil to a portion where there is little soil. The soil supply is stabilized.

When the amount of soil is small, the collecting plate 64
By bringing the soil on the inner side of the machine body to the left and right sides of the machine body, the soil is surely concentrated on the folded portion of the film D. Also,
When the amount of the soil is excessive, the flexibility allows the soil to escape toward the inside of the body, so that the soil is not clogged between the groove cutting plate F and the soil collecting plate 64.

The earth moving plate 63 is a bag-shaped portion S of the film D.
Further securing of the film D is ensured by further feeding of soil towards the.

As described above, according to the multi-working machine B2 of the second embodiment, the soil can be supplied to the bag-like portion S of the film D more reliably and stably.

In the above first and second embodiments,
Although the ridged rotor is not used, if the ridged rotor is connected between the tractor A and the multi-tasking machine B to perform chemical solution injection and film coating simultaneously with the ridger, the wheel marks of the tractor A There is an advantage that the soil surface C and the film D are brought into close contact with each other without forming voids due to the depressions such as the footprints of the worker, and the film D is less likely to come off.

The multi-working machine of the present invention can be used not only for soil disinfection but also for ridge coating similar to the conventional multi-working machine. In this case, the rows can be covered in close contact with each other without forming a soil-exposed portion between the covered surfaces of the rows, so that there is an advantage that the area of the field can be effectively used.

[0049]

According to the first aspect of the present invention, the left and right side edges of the film are folded to form a bag-shaped portion, and soil is supplied and fixed from the inside of the bag-shaped portion. Therefore, unlike the conventional device, it is not necessary to soil the both ends of the film, and it is possible to eliminate the risk that pathogenic bacteria will re-enter the soil from the soil thus soiled. Film is pre-coated according to the shape of the bag
Therefore, you can fix the film without pulling it, and the film
Do not tear it or the soil covered with the film will collapse.
Yes. In addition, since it is not necessary to scrape the soil on the left and right with the soil gathering disc, there is no gap between adjacent ridges and the entire surface of the soil can be covered without gaps, which reduces the disinfection effect due to the diffusion of chemicals and the risk of secondary pollution. It can be resolved.

In the second aspect of the invention, since the soil passes from the inside of the machine to the outside through the space between the film tension rod and the grooved plate, the soil can be reliably supplied to the bag-shaped portion .
