DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art A conventional multi-working machine is known which is provided with a groove cutting plate, a sponge roller for treading pressure, and a soiling disk symmetrically on the left and right sides of the machine. In this method, a film of a film roll is pulled out by a rolling sponge roller and both sides of the film are pressed against the ground, and the soil on both sides is scraped by the rolling of a mounting disc to hang the film on both sides of the film.

[0003] The original purpose of this type of multi-working machine is to keep the soil warm and water, but in addition to this, in recent years, applications for soil disinfection are expected. That is, in this type of work, a chemical injector is attached to a multi-working machine, the vehicle travels while injecting a chemical into the field scene after crushing, and is covered with a film immediately after the injection. In this case, in addition to the labor-saving effect that the chemical solution injection step and the coating step can be performed simultaneously, there is an advantage that the amount of the chemical solution can be reduced because the chemical solution is not easily diffused into the outside air.

[0004]

However, in the conventional multi-working machine, since it is necessary to scrape the soil on the left and right sides with the soiling disk, a gap is formed between the films covering the ridges. For this reason, when used for soil disinfection, the chemical solution diffuses from this gap and the disinfection effect is weakened,
In addition, there is a possibility that the surrounding environment may be adversely affected. In addition, since the film is fixed on both ends of the film and fixed, the soil used for the fixing cannot be disinfected, and there is a problem that the pathogenic bacteria re-enter the soil from there.

In view of the above problems of the conventional multi-working machine, the present invention provides a multi-working machine capable of completely covering the entire surface of the soil and preventing re-invasion of pathogenic bacteria from undisinfected soil. The purpose is to provide a machine.

[0006]

According to a first aspect of the present invention, an adhesive tape is provided on one of right and left skirts of a film while pulling out a belt-like film wound on a film roll to the ground. The remaining adhesive portion of the width is adhered, and then the soil is hung on the other hem of the film and fixed, and the excess adhesive portion of the adhesive tape is adhered on the adjacent existing film, and the entire surface of the ground is filmed. Characterized by being coated with

A second invention is a rotatable film roll on which a belt-shaped film is wound, a tread roller arranged on the right and left sides of the fuselage to tread the left and right hem of the film against the ground, and the tread pressure applied by the tread roller. A freely rotatable mounting disk that hangs soil on one hem of the film, a tape applicator that affixes an adhesive tape to the other hem of the film leaving a surplus adhesive portion of a predetermined width, and a rear side of the tape applicator. A fixing roller disposed on the film roll, whereby the film is pulled out from the film roll by the rolling of the stepping roller, and the excess adhesive portion is stepped on the adhesive tape stuck on the film by the fixing roller. Is bonded to an adjacent film.

In a third aspect of the present invention, a rotatable film roll having a band-shaped film wound thereon, a treading roller disposed on one of the right and left sides of the machine to tread the skirt of the film against the ground, and treading with the treading roller. A freely rotatable mounting disk that hangs soil on the hem of the film, a tape applicator for applying an adhesive tape to the other hem of the film leaving an excess adhesive portion of a predetermined width, and behind the tape applicator. A fixing device that also serves as a treading / pressing roller, wherein the treading roller and the treading / fixing roller are rolled to draw out a film from the film roll, and the treading / fixing roller is applied on an adhesive tape attached to the film. To adhere the surplus adhesive portion to an adjacent film.

[0009]

The multi-working machine according to the present invention is operated in parallel with the laid film so that a part of the traveling range overlaps the laid film. First, the tread roller rolls with the advance of the fuselage, and at the same time, the film pressed by the tread roller is pulled out from the film roll.

[0010] Here, the soil is placed on one hem of the film by means of an embedding disk, whereby the one hem of the film is fixed to the ground.

An adhesive tape is previously attached to the other skirt of the film by a tape applicator. The adhesive tape is further pressed by a fixing roller together with the adjacent laid film, whereby the other skirt of the film is adhered to the surface of the adjacent laid film, and the adjacent films are connected to each other.

As described above, in the present invention, one skirt of the film is fixed by the conventional embankment, but the other skirt is adhered to the surface of another laid film by the adhesive tape. By repeating this method, the films in each row are integrally connected to each other without any gap, so that the film can be entirely covered without exposing the soil surface of the field at all, and thus the disinfecting effect by the diffusion of the chemical solution can be achieved. The dangers of decline and secondary pollution can be eliminated. Further, since the soil used for the soiling is covered with the next row of films, the soiled soil can be disinfected well, thereby preventing the re-invasion of pathogenic bacteria.

Reference numeral 8 denotes a tension roller that guides the film D, and rotatably supports a cylindrical body on which a sponge is adhered to the tip of a J-shaped support arm 20.
Also, the left and right free ends protrude backward. 1
Reference numeral 0 denotes an inductor protruding from the left and right of the tension roller 8 and is formed of a flexible vinyl tube.

At the rear ends of the curved pieces 12, 12 of the main frame 5, rear frames 21, 21 are respectively extended rearward, and an inclined arm 22 is projected downward from the center of each rear frame 21. I do. One end of a swinging rod 23 is pivotally attached to the lower end of the inclined arm 22, and a sponge treading roller 7 is pivotally attached to the other end of the swinging rod 23 so as to freely rotate. Inclined arm 22
The link 22 connects the protruding piece 22a provided at the base of the swing rod 23 to the middle part of the swing rod 23, and the spring 24 is interposed in the link 24 to constantly urge the swing rod 23 downward. Therefore, the stepping roller 7 swings up and down by the elastic force of the spring 25.

As shown in FIG. 2, the embankment disks 9, 9 are arranged symmetrically, but the embankment disk 9 on the right side of the fuselage (virtual line in the figure) can be selectively used with the fixing roller 26. To be configured. That is, the rear frame 21
The rear end 27 is bent in the shape of a crank toward the inside of the machine, and a large-diameter cylinder 28 is fixed laterally to the rear end. Large diameter cylinder 2
A small-diameter cylinder 29, which is longer in the axial direction than the large-diameter cylinder 28, is freely inserted into the inside of the cylinder 8, and a vertical rod 33 is bolted on the front surface of the small-diameter cylinder 29 via a square cylinder 32 to adjust the height. Fasten. The fixing roller 26 is pivotally attached to the tip of the vertical rod 33 so as to freely rotate.

As shown in FIG. 3, a disk support arm 31 is fixed laterally on the upper surface of the small-diameter cylinder 29.
The hanging disk 9 is rotatably mounted on the distal end of the disk support arm 31 via a coupler 36 and a mounting rod 35. The connector 36 changes the direction of the hanging disk 9 by supporting the mounting rod 35 so as to be pivotable about its axis. The large-diameter cylinder 28 and the small-diameter cylinder 2
9 is provided with pin holes penetrating in the front-rear direction,
The pin 34 is inserted into this pin hole. Therefore, the pin 34
Is pulled out from the pin hole, the small-diameter cylinder 29 is turned 180 degrees in the large-diameter cylinder 28, and the pin 34 is inserted again, so that the mounting disk 9 and the fixing roller 26 can be switched (see FIG. 4).

As shown in FIG. 5, the grooved plate 6 on the right side of the fuselage is fixed to the lower end of the vertical rod 13.
Is pivotally connected to a lower end of a protruding piece 41 provided downward from the horizontal rod 11 with a bolt 15. A rearward-facing locking piece 42 is protruded from the horizontal rod 11, and a distal end of the locking piece 42 and a pin 43 mounted laterally in the middle of the front end surface of the vertical rod 13 are constantly pulled by a spring 44. Connect to state. Accordingly, when the vertical rod 13 is pivoted downward, the pin 43 comes into contact with the front end face of the protruding piece 41 by the pulling of the spring 44, so that the grooved plate 6 is held at the downward movement position, and is indicated by an arrow F in the figure. When the vertical piece 56 is pivoted upward as described above, the spring 44 crosses the rotation axis of the bolt 15 and the grooving plate 6 is held in a state of jumping upward by the traction force of the spring 44.

On the other hand, a tape holder 46 is mounted rearwardly adjacent to the base of the curved piece 12 on the right side of the fuselage, thereby holding the adhesive tape 47 freely. A tape applicator 61 is provided below the tape holder 46. The tape sticking device 61 rotatably supports the sticking roller 48 at the tip of the turning rod 49, and has a spring 50 interposed at the base of the turning rod 49, and constantly presses the fixing roller 48 toward the film roll 15. , Whereby the peripheral surface of the attaching roller 49 and the peripheral edge of the skirt of the film roll 15 are pressed against each other. The adhesive tape 47, the sticking roller 48, and the above-described fixing roller 26 are arranged so as to be aligned in a straight line along the skirt 54 of the film D when viewed from above, as shown in FIG.

The operation steps of simultaneously performing the soil disinfection operation and the film coating operation using the multi-operation machine of the present invention will be described with reference to the drawings.

In FIG. 1, when the engine 1 is started, its power is transmitted to the driving wheels 3 and the body advances in the direction of arrow G. The operator works while retreating while holding the handle 2. First, as the airframe advances, a chemical liquid injector E injects a chemical liquid into the soil approximately every 30 cm before and after. Of course, an appropriate amount of a chemical solution may be continuously injected.

Immediately after the chemical solution is injected, the soil surface is covered with the film D immediately in the present embodiment. It is to be laid in a way of hanging.
That is, in the film coating step in the first row, as shown in FIG.
6 is raised and the work disk 9 is lowered. Here, the adhesive tape 47 is not used.

First, grooves are formed on the left and right sides of the fuselage by the groove cutting plates 6 and 6. On the other hand, as the fuselage advances, the treading roller 7 rolls on the ground, and by this rolling, the film D, which has been treaded on both left and right hem by the treading roller 7, is sequentially guided by the tension roller 8 and the inductor 10. Drawn out. Then, the soiling disc is rolled on both sides of the film D which has been treaded, and the soil is hung thereon, thereby fixing the film D in the first row to the ground. When the coating process in the first row is completed in this way, the operator appropriately cuts the film D, moves the machine, and shifts to the coating process in the second row.

In the coating process in the second row, the work is performed in a state where the grooved plate 6 on the right side of the machine body is flipped forward and the fixing roller 26 is lowered instead of the soiling disk 9 as shown in FIG. . The adhesive tape 47 has one end drawn in advance introduced between the attaching roller 48 and the film roll 15 and is attached to the side end of the film roll 15 except for an excess adhesive portion 56 whose adhesive surface is exposed downward. Keep it. The width of the surplus adhesive portion 56 is substantially half the width of the adhesive tape 47.

Thus, in the second-row coating step, a part of the traveling range is overlapped with the laid film D1 along the first-row film D1 (see FIG. 6) already laid. And drive in parallel. First, the tread rollers 7, 7 roll on the ground with the advance of the machine body, and at the same time, the film D2 whose both skirts are tread by the tread roller 7 is pulled out from the film roll 15.

Here, the soil is placed on the left side hem 57 of the film 2 by the embankment disk 9 in the same manner as in the case of the film D1 in the first row described above.
The second hem 57 is fixed to the ground.

On the other hand, at the right foot 54 of the film D2 in the figure, unlike the case of the first row described above, the adhesive tape 47 attached to the foot is sequentially drawn out as the film D2 is pulled out. , And by the pressure of the attaching roller 48,
It is continuously adhered to the skirt of the film D2. Then, the adhesive tape 47 is stepped on by the fixing roller 26, whereby the excess adhesive portion 56 is fixed to the film D1, and the skirt 54 of the film D2 is connected to the surface of the laid film D1.

Similarly to the case of the second row, the coating process for the third and subsequent rows is performed in a state where the grooved plate 6 on the coated side is flipped up and the fixing roller 26 is lowered. In this way, one after another,
The soil in each row is disinfected and covered with film D (see FIG. 7). When planting a crop after disinfection, the film D is peeled off from the soil surface, cultivated and ridged, and then planted.

As described above, in the first embodiment, the film D2
Of the film D1 is adhered to the surface of the laid film D1 with an adhesive tape 47. Therefore, the film D1 in the first row and the film D2 in the second row are integrally connected to each other without any gap. Further, by repeating this method in the third and fourth rows, the soil surface of the field can be completely reduced. The entire surface can be covered without being exposed, thereby reducing the disinfecting effect due to the diffusion of the chemical solution and eliminating the risk of secondary pollution. In addition, soil that cannot be disinfected conventionally can be disinfected well because it is covered with the next row of film, and undisinfected soil is only one side of the first row and one side of the last row. And the amount can be minimized, thereby preventing the re-invasion of pathogenic bacteria. In addition, since one side edge of each film in each row is fixed to the ground by soiling, the film does not peel off unnecessarily due to wind or the like.

In the film laying process for the second and subsequent rows, the grooved plate 6 on the side of the coated film D1 (that is, the right side of the machine) is raised as shown in FIG. There is no risk of breakage at the cutting plate 6.

Further, since the configuration is such that the mounting disk 9 on the right side of the machine and the fixing roller 26 are switched by inserting and removing the pin 34, when shifting from the coating process in the first row to the coating process in the second and subsequent rows. The advantage is that the mounting disk 9 and the fixing roller 26 can be quickly exchanged with a small effort.

In the multi-working machine B of the first embodiment, only the grooved plate 6 and the embankment disk 9 on the right side of the machine can be flipped up or switched freely, and the adhesive tape 47, the sticking roller 48 and the like are also provided only on the right side of the machine. Although the left and right asymmetrical configuration is provided, instead of such a configuration, the groove cutting plate 6 and the soiling disk 9 on the left side of the fuselage can be flipped up or switched similarly to the right side of the fuselage, and further, an adhesive tape, a sticking roller and a fixing roller And the like may be provided on the left side of the fuselage, and the entire fuselage may be configured symmetrically. In this case, after the completion of the covering of one row of ridges, the direction of the fuselage can be directly inverted by 180 degrees, and the next row can be covered next to the currently coated film, and the folding operation can be performed. Therefore, there is an advantage that work efficiency can be improved.

FIGS. 8 and 9 show a second embodiment, in which the first embodiment is used.
One of the stepping rollers 7 in the embodiment and the fixing roller 2
6 is integrated into a fixing roller 80 that also serves as a stepping pressure. In this case, there is an advantage that the number of parts is reduced and the structure is simplified as a whole.

In FIG. 8, the imaginary line 9 indicates an embankment disk.
Equipped interchangeably with In addition, the same structures as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

[0037]

As described in detail above, according to the present invention, one hem of the film is fixed by conventional soiling, but the other hem is adhered to the surface of the next laid film by an adhesive tape. I do. Therefore, in the present invention, by repeating this method, the films in each row are integrally connected to each other without gaps, so that the entire surface can be covered without exposing the soil surface of the field at all, and thus, the chemical solution is diffused. It is possible to eliminate the risk of disinfection effect and secondary pollution.
Further, since the soil used for the soiling is covered with the next row of films, the soiled soil can also be disinfected well, thereby providing an excellent effect of preventing re-entry of pathogenic bacteria.
