  However, when the multi-film S laid on the kamaboko-shaped cocoon U used for cultivation of sweet potatoes, potatoes, taro, tobacco, etc. is pulled up and collected, the multi-film S The distance to the guide roller 82 is different between the substantially central portion Sa in the width direction and both end portions Sb in the width direction. For this reason, during the collection of the multi-film S, a slack R is generated in the center portion Sa in the width direction of the multi-film S between the upper surface of the bag and the guide roller 82. As a result, the soil that has been scooped up from the ridges accumulates in the slack R of the substantially central portion Sa in the width direction of the multi-film S, and the collection work is hindered. There is a problem of doing.

In order to solve the above problems, the sheet collecting apparatus of the present invention is:
It is mounted on a work machine supported so as to be able to travel along the fence,
A sheet feed roller supported so as to be rotatable around an axis extending in the width direction of the ridge above the ridge in order to peel off the sheet stretched on the ridge;
A sheet collection unit that draws and collects the sheet via the upper side of the sheet feed roller,
A sheet collecting apparatus configured to sequentially collect the sheets from one end side of the sheets while proceeding along the ridge by the working machine,
The sheet feeding roller is formed such that the diameter of the substantially central portion in the width direction is relatively larger than the diameter of both end portions in the width direction.

  According to this configuration, the sheet feeding roller is formed so that the diameter of the substantially central portion in the width direction is relatively larger than the diameter of both end portions in the width direction. In addition, it is possible to prevent slack from occurring in the substantially central portion in the width direction of the sheet. For this reason, generation | occurrence | production of the malfunction by this loosening can be suppressed and smooth collection | recovery operation | work can be performed.

Although it does not specifically limit as said sheet | seat feed roller, The following aspect is illustrated.
(1) The aspect formed in the bead shape of the abacus.
(2) The aspect formed by the cylindrical part extended in the said width direction, and the flange part protrudingly provided by the approximate center part of the said width direction in this cylindrical part.
(3) An aspect formed in a spherical shape (including an elliptical shape).

  According to the sheet collecting apparatus of the present invention, when the sheet is peeled off from the ridge, there is an excellent effect that it is possible to prevent the slack from occurring in the substantially central portion in the width direction of the sheet.

  1 to 3 show a sheet collecting apparatus 1 according to an embodiment of the present invention. As shown in FIGS. 1 and 2, the sheet collecting apparatus 1 of this example is mounted on the front side of a moss harvesting machine 2 as a working machine configured to be able to travel along the cocoon U, The multi film S is sequentially collected from one end side of the multi film S while proceeding from one end side to the other end side of the multi film S as a sheet along the ridge U by the machine 2. . In this example, as shown in FIG. 2, the multi-film S is laid so as to cover the entire surface of the ridge U (the upper surface of the ridge U and both side surfaces continuous from the upper surface) formed in a substantially scallop shape. However, the present invention is not limited to this, and for example, it may be laid so as to cover the upper surface of the ridge U and upper portions of both side surfaces continuous from the upper surface. In each figure in this document, the arrow F indicates the front side of the aircraft.

  The potato harvester 2 is configured to be able to travel along the ridge U, and the culvert collecting conveyor device 12 attached to the front end side thereof, and the heel following device attached to the conveyor front side portion of the culvert digging conveyor device 12 13. The hail follower 13 includes a pair of hail guide rollers 14 disposed on both sides of the hail U so that the peripheral surface abuts on the side surface of the hail U and rolls as the hull harvester 2 moves. ing.

  In order to peel off the multi-film S stretched on the ridge U, the sheet collecting apparatus 1 includes a sheet feed roller 22 that is rotatably supported around a shaft 21 extending in the ridge width direction above the ridge, and the multi-film S. In order to apply tension to the sheet feeding roller 22, the tension roller 23 provided obliquely below the sheet feeding roller 22 and the multi-film S passing through the upper side of the sheet feeding roller 22 are wound on the winding drum 24. And a sheet collecting unit 25 for collecting the sheet.

  In this example, the sheet feeding roller 22 is formed in a abacus bead shape, that is, formed so that the diameter of the substantially central portion 22a in the width direction is relatively larger than the diameters of both end portions 22b in the width direction. Has been. On both sides of the sheet feeding roller 22, in order to prevent displacement of the multi-film S in the width direction, a displacement prevention member 22c formed in a flange shape is provided. The material of the peripheral surface of the sheet feeding roller 22 is not particularly limited, but a material made of resin is exemplified. The shape of the sheet feeding roller 22 is not limited to this. For example, as shown in FIG. 3A, a cylindrical portion 26 extending in the width direction (the axial length direction of the shaft 21), and the cylindrical portion 26 described above. Examples of an aspect formed by the flange portion 27 projecting substantially at the center in the width direction, an aspect formed in an elliptical shape as shown in FIG.

  Next, the operation of the sheet collecting apparatus 1 will be described. First, as a preparation, the end of the multi-film S laid on the ridge U is peeled off by several meters behind the ridge guide roller 14, and passed through the sheet feed roller 22 and the tension roller 23 in that order. It is fixed to the drum 24. When the sheet collecting apparatus 1 is operated together with the moss harvesting machine 2, the sheet collecting unit 25 is activated and the winding drum 24 is rotated. Further, the multi-film S is pulled up almost directly and collected into the take-up drum 24. At this time, the sheet feeding roller 22 is formed such that the diameter of the substantially central portion 22a in the width direction is relatively larger than the diameter of the both end portions 22b in the width direction. Further, the looseness of the substantially central portion Sa in the width direction of the multi-film S is largely eliminated by the tension imparted by the bulging of the substantially central portion 22a in the width direction of the sheet feeding roller 22.

  According to the sheet collecting apparatus 1 of this example configured as described above, the sheet feeding roller 22 is configured such that the diameter of the substantially central portion 22a in the width direction is relatively larger than the diameters of the both end portions 22b in the width direction. Therefore, when the multi-film S is peeled off from the ridge U, it is possible to prevent the slack from occurring in the substantially central portion Sa in the width direction of the multi-film S. For this reason, generation | occurrence | production of the malfunction by this loosening can be suppressed and smooth collection | recovery operation | work can be performed.

  Further, in this example, the multi-film S is pulled up almost directly from immediately after the straw guide roller 14 of the straw harvesting machine 2 and collected to the winding drum 24. As a result, the multi-film S is peeled off after breaking the ridge U on which the multi-film S is laid by the moat 12a of the coffin-digging conveyor device 12 located behind the coffin guide roller 14. The multi-film S can be collected very smoothly without being affected by the embedding depth of the edge of S or the field conditions such as an inclined land. For this reason, it is possible to prevent problems such as the multi-film S being cut during collection.

In addition, this invention is not limited to the said embodiment, For example, it can also be suitably changed and embodied as follows, for example in the range which does not deviate from the meaning of invention.
(1) The sheet collecting apparatus 1 according to the present invention is mounted on a machine body configured to be able to travel in the field, thereby configuring as a sheet collecting dedicated machine.
