The traveling machine body 1 may have a structure including a plate-shaped or bar-shaped grounding portion that can slide on the ground instead of the auxiliary wheel 1b.

  As shown in FIG. 2, the floating device 3 has an L shape with a toe horizontally formed, and a plurality of bolt holes 3a for height adjustment are opened at the top, and a multi-film F is guided upward at the rear of the toe. It is formed in a curved surface for easy. The upper part of the float 3 is slidably inserted into a holder 3b provided on the left and right sides of the drawing device 2 and fixed with bolts 3c. Before use, an arbitrary bolt hole 3a is selected according to the height of both sides of the multi-film F, and the height of the toe is adjusted.

  The anti-lifting guide 4 prevents excessive lifting of the multi-film F when the foliage P is pulled out. As shown in FIGS. 3 and 4, the entire anti-lifting guide 4 has a rod shape and is bent at both ends so that the multi-film F is not caught. An attachment plate 4a having a long hole is provided in the middle part thereof. The two anti-lifting guides 4 are attached to a mounting plate 4c suspended below the drawing device 2 by a support column 4b horizontally by bolts 4d and at a position higher than the flange A at a narrow interval. Before use, the front and rear positions are adjusted by loosening the bolts 4d according to the height of the float 3 and the dimensions of the multi-film F.

  As shown in FIGS. 5 to 7, the feed roller 5 has shafts 5 a protruding at both ends, and the diameter of the shaft 5 a is reduced. A pair of arms 5b are attached to the rear frame 1f of the traveling machine body 1 so as to be rotatable in the vertical direction by the rotation shaft 5c and at a distance narrower than the distance between the left and right main wheels 1a. A bearing hole 5d through which the shaft 5a can be inserted and removed is opened, and a bearing recess 5e into which the shaft 5a can be fitted from above is formed at the end of the other arm 5b. At the position of the bearing recess 5e, a presser piece 5g with a spring 5f for preventing the shaft 5a from falling off is provided so as to be releasable. The rotating shaft 5c is provided with a bolt 5h that regulates the downward rotation of the arm 5b by contacting the bottom surface of the traveling machine body 1.

  When the feed roller 5 is attached to the left and right arms 5b, the arm 5b is lowered by its own weight, the bolt 5h comes into contact with the bottom surface of the traveling machine body 1, the lowering of the arm 5b is restricted, and the height of the feed roller 5 is maintained. The When the feed roller 5 is lifted, the arm 5b can freely rotate upward. This bolt 5h serves as a stopper for lowering the feed roller 5, and the amount of protrusion can be changed to adjust the height A to various heights. Further, the pair of arms 5b are narrower than the distance between the left and right main wheels 1a, so that the multi-film F passing under the traveling machine body 1 is prevented from being caught in the main wheels 1a. It has become.

  In this embodiment, as shown in FIGS. 8 and 9, the traveling machine body 1 is arranged in the field so as to straddle the ridge A, and the left and right floats 3 are adjusted according to the heights on both sides of the multi-film F, and bolts In 5 h, the feed roller 5 is adjusted to a height that does not contact the heel A. Then, the engine 1d is started and the operator operates the handle 1e to run. In the drawing device 2, the left and right scraping belts 2a scrape the foliage P toward the center of the traveling machine body 1, and are pulled out by the left and right pulling conveyance belts 2b and conveyed upward. The multi-film F is prevented from being lifted by the pressing member 1c when the foliage P is pulled out.

  The left and right floats 3 are inserted between the multi-film F and the ridge A after the foliage P has been pulled out, and the multi-film F floats as the traveling machine body 1 moves forward. At this time, although the multi-film F may be attached to the extracted stems and leaves P and try to float up excessively, it is restrained by the lifting prevention guide 4 and is prevented from being caught or caught in the drawing device 2. . The floated multi-film F is placed on the feed roller 5 by the operator passing only between the left and right arms 5b or standing up one side of the feed roller 5 for the first time.

  Thereafter, as the traveling machine body 1 moves forward, the multi-film F floated by the floating device 3 is sent to the center side of the traveling machine body 1 in contact with the vertical portion of the floating device 3 and passes below, and the traveling machine body 1 is fed by the feed roller 5. The process is continuously performed in parallel with the extraction of the foliage P. The multi-film F placed on the feed roller 5 may shift or spread to the left and right during guidance, but does not protrude outwardly in contact with the arm 5b and does not get caught in the main wheel 1a. The multi-film F placed on the basket A can be easily collected manually by the operator after the foliage P is pulled out.

  When processing the multi-film F of the adjacent kite A, as shown in FIG. 10, the front of the traveling machine body 1 is tilted and turned up, but at that time the arm 5b freely rotates upward. Since it is possible, the feed roller 5 is lifted in contact with the ridge A. Thereby, the feed roller 5 can be smoothly turned without interfering with the ridge A. Thereafter, when the posture of the traveling machine body 1 is returned to the original position, the feed roller 5 is lowered by its own weight, but is maintained at a predetermined height by the bolt 5h, and the processing can be resumed immediately without readjustment.

  As described above, according to the present embodiment, the extraction of the foliage P and the peeling of the multi-film F are performed in parallel, so that the work can be performed in a shorter time compared to the prior art. Moreover, since the member required for peeling off the multi-film F has no driving part and has a simple structure, it can be reduced in weight as compared with a conventional foliage processing machine and can be manufactured at a low cost.

  FIG. 11 shows another example of the feed roller of this embodiment. The feed roller 5 in this example includes a cylindrical intermediate roller 5i, a compression spring 5j inserted into the intermediate roller 5i, and an outer roller 5k with shafts 5a inserted from both sides of the intermediate roller 5i. The entire structure can be expanded and contracted.

  When mounting, the outer roller 5k is pushed in the direction of the intermediate roller 5i and the compression spring 5j is compressed and placed between the left and right arms 5b. The outer roller 5k is released and the shaft 5a is moved by the repulsive force of the compression spring 5j. It is pivotally supported on the arm 5b. When removing, the outer roller 5k is pushed in the direction of the intermediate roller 5i to compress and remove the compression spring 5j. In other respects, the reference numeral, the configuration, and the operational effects are the same as in the embodiment.

  The technique of the present invention is suitable for harvesting potatoes, but can be applied to harvesting crops cultivated using multi-film. Further, it may be used only for multi-film processing.
