Embodiment A partly omitted plan view of an embodiment of the present invention will be described with reference to FIG. 1, a vertical sectional view thereof, FIG. 2, a side view thereof, and a front view in the same working state. To do.

Reference numeral 10 is a mounting frame. Reference numeral 12 denotes a side plate that constitutes a side frame of the foliage processing machine, and is attached to both ends of the mounting frame 10 to form a frame of the foliage processing machine as a whole.

Reference numeral 1 denotes a main mission, which is attached to the center of the mounting frame 10. Reference numeral 2 denotes an input shaft, which is rotatably driven by being connected to power of a tractor or the like to which the foliage processing machine is towed. In the mission 1, a bevel gear 31 is provided at the end of the input shaft 2, and a bevel gear 32 and a bevel gear 33 are meshed with the bevel gear 31, respectively. The first output shaft 3 is attached to the bevel gear 32, and the second output shaft 4 is attached to the bevel gear 33. Since the first output shaft 3 and the second output shaft 4 are directly attached to the bevel gear 32 and the bevel gear 33, they are rotated in the opposite directions as the input shaft 2 rotates. Reference numerals 34 and 35 denote pipe frames, which respectively have the first output shaft 3 and the second output shaft 4 built therein and are attached to the mounting frame 10.

Reference numeral 11 denotes a horizontal box, which is provided in the rear portion of the foliage processing machine in parallel with the first output shaft 3 and the second output shaft 4, and is supported by the side plate 12. The transmission shaft 8 is installed in the horizontal box 11. Reference numeral 9 denotes an intermediate shaft, which is provided midway between the transmission shaft 8 and the first output shaft 3 and the second output shaft 4 in parallel with them, and is supported by the side plate 12.

Reference numerals 35 and 36 are cutting blade support frames. One end of each of the cutting blade support frames 35, 36 is attached to the periphery of the intermediate shaft 9 and the other end constitutes a free end. The cutting blades 5 are provided on both outer sides of the holding device 41 in parallel to the traveling direction and rotatably provided by a rotating shaft.

Reference numeral 7 is a rotating shaft. The rotary shaft 7 is provided behind the transmission shaft 8 in parallel with the transmission shaft 8 and between the side plates 12. 6 is a crushing device. The crushing device 6 is configured by arranging a large number of crushing blades 37 around the rotating shaft 7, and rotationally drives and crushes the conveyed foliage.

Reference numeral 18 is a first transmission band, 19 is a second transmission band, and 20 is a third transmission band. The first transmission band 20 is bridged between the first output shaft 3 and the rotary shaft 7. The second power transmission band 19 is bridged between the second output shaft 4, the intermediate shaft 9, and the transmission shaft 8. The third transmission bands 20, 20 are bridged between the intermediate shaft 9 and the rotary shafts of the respective cutting blades 5. Therefore, as shown in FIG. 3, the rotation input from the input shaft 2 enters the main mission 1 and the first output shaft 3, and the rotation shaft 7 and the crushing device 6 are driven through the first transmission band. Rotate in _two directions, that is, in the scraping direction. As shown in FIG. 2, the rotational force transmitted from the main mission 1 to the second output shaft 4 in the direction opposite to the rotation of the first output shaft 3 causes the transmission shaft 8 and the intermediate shaft 9 to rotate. The cutting blade 5 is rotated to rotate in the f ₁ direction, which is the rotation direction following the progress of the foliage processing machine in the direction opposite to the crushing device 6.

Reference numeral 21 denotes a speed change case, which converts the rotation of the transmission shaft 8 into a vertical direction and drives the pair of drive rollers 38 in opposite directions. That is, 51 and 52 are bevel gears that are installed on the transmission shaft 8 with their meshing surfaces facing each other. The bevel gears 51 and 52 mesh with a bevel gear (not shown) attached to the lower ends of the rotation shafts 53 and 54 of the drive roller 38. Since the bevel gears 51 and 52 are provided alternately, the rotation shafts 53 and 54 of the drive roller 38 rotate in mutually opposite directions.

Reference numeral 41 is a holding device. The holding device 41 includes a pair of endless conveyors 13 and 13. The endless conveyors 13 and 13 are opened in a V shape on the front side in a plan view, and the central portions of the endless conveyors 13 and 13 are in close contact with each other with the conveyor surfaces facing each other, and the endless conveyors 13 and 13 are mounted between the drive roller 38 and a driven roller 39 provided in front of the drive roller 38. Passed. The endless conveyor 13 is moved rearward by the drive roller 38 so that the surfaces of the rollers facing each other are moved together. A pressing roller 16 is installed below the openings of the pair of endless conveyors 13.

Since the foliage processing machine according to this embodiment is for two ridges, the sandwiching device 41 composed of a pair of endless conveyors 13 is arranged between the facing surfaces of the sandwiching devices 41 as shown in FIG. The two spaces are installed corresponding to the space between the ridges. The holding device 41 may be installed according to the number of ridges to be processed.

Reference numeral 14 is a guide. The guide 14 is projected between the holding devices 14, that is, at the ridge groove position provided between the ridges. Reference numeral 15 is a guide rod, and as shown in FIGS. 2, 3, and 4, the front end is attached to the guide 14 by inclining backward, and the rear end is extended above the front end of the endless conveyor 13, and a plurality of guide rods are provided. To be

Reference numeral 17 denotes a grounding wheel, which cushions and supports the machine body via a cushion bar 22.

Next, the operation of the embodiment will be described. A foliar treatment machine is introduced into the field, two cultivation ridges are straddled, and the facing surface of the endless conveyor 13 of each sandwiching device 41 is run along the ridges.

Then, since the foliage is cut by the cutting blades 5 which are rotated on both outer sides in the f ₁ direction, the foliage is separated by the cutting blades 5 even if the foliage is mat-shaped. When the trunk portion of the foliage is sandwiched by the endless conveyor 13, immediately after that the pressing roller 16 presses the surface of the ridge, so that the foliage is cut off from the potato. The separated foliage is lifted by the guide 14 and the guide rod 15 and guided onto the sandwiching device 41, sandwiched by the endless conveyor 13 of the sandwiching device 41, and conveyed backward.

The foliage conveyed rearward is crushed by the crushing blade 37 of the crushing device 6 which is rotated in the f ₂ direction.

[0027]

[Effects of the Invention] Therefore, according to this invention, smooth work can be performed even on a so-called mat-shaped foliage of a plurality of cultivated ridges that are entangled with each other, and the drive transmission section is simplified.
