In the working machine, the cultivation of the field and the feeding of the film sheet are performed while traveling back and forth along one direction of the field, so that a film sheet having a predetermined width is stretched adjacently. It becomes a state. In this case, it is conceivable that the stretched film sheet moves or flips up due to wind or the like, so it is necessary to hold down the stretched film sheet. The present invention is directed to a working machine configured to feed out a film sheet having a predetermined width while tilling a field by a tilling device and stretch the film sheet so as to cover the surface of the tilled soil. It is an object of the present invention to obtain a configuration that can reliably hold a film sheet.

[0004]

The feature of the present invention resides in that the working machine is constituted as follows. [1] A traveling machine is provided with a tilling device and a sheet feeding portion for feeding a film sheet of a predetermined width stretched so as to cover the surface of the cultivated soil, and a sheet feeding portion for a film sheet fed from the sheet feeding portion. Away from
It is provided with a guide member for guiding to the surface of the soil cultivated in contact with the place, and a tape feeding portion for feeding the adhesive tape, and is fed from the tape feeding portion to a lateral edge portion of the film sheet fed from the sheet feeding portion. Adhesive tape is stuck so as to protrude laterally outward at the position of the guide member, and the film sheet to which the adhesive tape is stuck is stretched adjacent to the already stretched film sheet, and is stretched. The structure is such that the lateral edge of the unwound film sheet is attached to the lateral edge of the film sheet using an adhesive tape.

[2] In the configuration of the above- mentioned [1], a film fed out so as to cover a surface of the soil supplied with the chemical is provided with a chemical supply device for supplying a chemical to the soil plowed by the tillage device. It is configured so that the sheet is stretched.

[0006]

According to the first aspect of the present invention, the tilling is performed by the tilling device with the progress of the traveling body, and a film sheet having a predetermined width is fed out to cover the surface of the tilled soil. A sheet is stretched. In this case, the adhesive tape is fed out from the tape feed-out portion, and the horizontal edge of the film sheet already stretched and the horizontal edge of the fed-out film sheet are adhered by the adhesive tape.

According to the first aspect of the present invention , in a state where the film sheets having a predetermined width are stretched adjacent to each other, the adjacent film sheets are attached to each other by the adhesive tape and connected. The stretched film sheet does not move or flip up due to wind or the like.

[II] As described in the above item [I], when the lateral edge of the unwound film sheet is adhered to the lateral edge of the already stretched film sheet with an adhesive tape, for example, as shown in FIG. The structure shown is conceivable. The structure shown in FIG. 7 is configured such that the film sheet S is fed out from the sheet roll 22 in a state where the film sheet S is stacked in a roll shape and wound, and is stretched on the surface of the soil by the pressure reduction roller 26. Have been. In a portion where the adhesive tape T is fed out from the tape feeding section 35 in a state where the adhesive tape T is stacked and wound in a roll shape, and the film sheet S is fed out from the sheet roll 22, the portion of the film sheet S (sheet roll 22). The adhesive tape T is adhered to the lateral edge, and the adhesive tape T is pressed by the spreading wheel 50. Thereby, with the feeding of the film sheet S, the adhesive tape T is also sent out together with the film sheet S, and is adhered to the film sheet S already stretched.

However, with the configuration shown in FIG.
In the lateral edges of the film sheet S (the sheet roll 22) wound in a roll shape, the lateral edges of the film sheet S in the laminated state may not be arranged in an orderly manner, and the lateral edges of the film sheet S may be laminated due to the vibration accompanying the work. The state is disturbed and the film sheet S
May be shifted laterally. Thus, in the state described above, when the adhesive tape T is attached to the lateral edge of the film sheet S (the sheet roll 22) stacked and wound in a roll shape, the adhesive tape T is attached to the middle film sheet. For example, the adhesive tape T may be stuck to the lateral edges of the film sheet S on which the adhesive tape T is laminated, and may be attached to a plurality of lateral edges of the film sheet S. Therefore, when the film sheet S is fed out together with the adhesive tape T in such a state, the film sheet S on the middle side is forcibly fed out, and the film sheet S is damaged or the film sheet S is distorted. They may try to be paid out.

[III] Further, according to the feature of the first aspect , the film sheet is fed in a single layer state from the sheet feeding section, and the single-layer film sheet is separated from the sheet feeding section by the guide member.
Was in contact at a point, which is configured to be guided to the surface of the tilling soils, adhesive tape fed out from the tape supply portion, the lateral edges of the fed-out film sheet at the position of the guide member, The film sheet is attached so as to protrude to the lateral outside, and the film sheet is fed out together with the adhesive tape from the position of the guide member.

[0011] According to the first aspect of the present invention, the film sheet (sheet roll) laminated and wound in a roll shape is fed out instead of the lateral edge portion.
Of the film sheet that has become a single layer at a location away from the part
Since the adhesive tape is stuck to the lateral edge so as to protrude outward in the lateral direction, the state in which the adhesive tape is stuck over a plurality of lateral edges of the film sheet on which the adhesive tape is laminated as described in the preceding section [II] is described. Does not occur. Therefore, when the film sheet is fed out together with the adhesive tape from the position of the guide member, the film sheet on the middle side is forcibly fed out, and the film sheet is damaged, or the film sheet tries to be fed out in a distorted state. I will not do it.

[IV] According to the feature of claim 2 , similar to the case of claim 1 , the "action" described in the above [I] and [III] is provided, and in addition to this, the following "action" is provided. "Is provided. Some work machines include a chemical supply device that supplies a chemical (eg, a disinfectant for soil) to the soil plowed by the tillage device. According to the features of claim 2 , the surface of the soil to which the chemical is supplied is provided. The drawn-out film sheet is stretched so as to cover, and the adjacent film sheets are attached to each other by an adhesive tape and connected.

Thus, according to the second aspect of the present invention, the adjacent film sheets are connected to each other by being adhered to each other by the adhesive tape, and the stretched film sheet is moved or turned up by wind or the like. As a result, it is possible to suppress a situation in which the drug comes out of the field and the effect of the drug is impaired.

[0014]

According to the first aspect of the present invention, a film sheet having a predetermined width is fed out while tilling a field by a tilling device, and the film sheet is stretched so as to cover the surface of the tilled soil. In such a working machine, by configuring the adjacent film sheets to be bonded and connected to each other by the adhesive tape, the stretched film sheet does not move or turn up due to wind or the like. Thus, the effect of stretching the film sheet (for example, keeping the field warm) can be improved.

Further, the adhesive tape is stuck to the lateral edge portion of the single-layer film sheet fed at the position of the guide member so as to protrude laterally outward, so that the adhesive tape is adhered from the position of the guide member. When the film sheet is fed out together with the tape, the film sheet is not damaged, and the film sheet does not try to be fed out in a distorted state, so that the stretched film sheet moves or turns due to wind or the like. Such an increase was further eliminated, and the effect of stretching the film sheet (for example, keeping the field warm) could be further enhanced.

According to the characteristics of claim 2 , the "effect of the invention" of the above-mentioned claim 1 is provided similarly to the case of the claim 1, and in addition to the "effect of the invention", Such an "effect of the invention" is provided. According to the features of claim 2 , a chemical (for example, a soil disinfectant, etc.) is applied to the soil tilled by the tilling device.
In a working machine equipped with a drug supply device for supplying the drug, it is possible to suppress a state where the drug goes out of the field and the effect of the drug is impaired, and the effect of the drug can be enhanced.
