[0011]
In order to use the foliage processing machine 1 of the present embodiment, the pulling and conveying belt 5 is positioned on each of the two ridges of the potato field at the time of harvesting, while driving each belt and each roller by driving the engine 18. It is advanced by the crawler 19. The leaves 30a of the potatoes, including those that have fallen, are guided toward the center of the row by the divider 2 toward the raking belt 3. In the scraping belt 3, the leaves 30 a are scraped between the belts at the front end of the pull-out conveyance belt 5 by the protrusions of the belt. The foliage 30a sandwiched between the front ends of the pull-out transport belt 5 is strongly held by the facing belt surfaces, and is transported diagonally upward along the pull-out transport belt 5. At this time, the root portion of the foliage 30a enters between the two rods of the potato retainer 16. When the foliage 30a moves obliquely upward by the pull-out transport belt 5, if the potato 30 remains strongly in the soil, the foliage 30a is separated so as to be pulled out at the root portion, and the potato 30 is moved upward together with the foliage 30a. When trying to move, the potato 30 is securely caught on the potato holder 16 at the narrow interval A so that the potato 30 and the foliage 30a are surely separated. Therefore, the foliage 30a is reliably pulled out of the potato 30 and the root portion does not remain largely in the ground, so that secondary growth of the potato 30 can be stopped, and the commercial value is enhanced.
When the foliage 30a separated from the potatoes moves further obliquely upward and backward by the pull-out transport belt 5, the upper part of the foliage 30a is lightly held by the facing belt surface of the upper transport belt 7 during the transport. It will be. The upper transport belt 7 is parallel to the pull-out transport belt 5, but has a higher belt speed than the pull-out transport belt 5. In the foliage processing machine 1 of this embodiment, the speed of the upper conveyor belt 7 is about 1.5 times as high as the feed speed of the pull-out conveyor belt 5. Therefore, by moving the upper part of the foliage 30a conveyed in a slightly forwardly inclined state following the inclined pulling-out conveyance belt 5 at a high speed, the forward inclination of the foliage 30a can be made almost vertical.
[0012]
When the foliage 30a is sent further rearward in this manner, the foliage 30a is released from the pull-out transport belt 5, since the rear end of the upper transport belt 7 projects rearward from the rear end of the pull-out transport belt 5, The upper part is held down and hangs down to become nearly vertical, and then falls below the rear end. Since the fallen foliage is surrounded by the chute 9, the fallen foliage is sent to the guide roller 10 in a standing state without tilting to a lying state, and is guided between the rollers by the rotation of the guide roller 10. Since the feed roller 11 is located below the guide roller 10, the foliage 30a gradually bites between the two rollers of the feed roller 11 so as to bite between the alternately arranged annular blades 11a and 11b. Sent down. Therefore, the foliage 30a is sent downward while being held back and forth and right and left by the opposed roller and the annular blades 11a and 11b. Therefore, the foliage 30a is sent gradually downward from the lower end in the upright state.
When the lower end of the foliage 30a gradually fed downward by the feed roller 11 comes below the fixed blade 13a of the foliage crushing device 13, the foliage whose upper part is supported by the rotating blade 13b is fixed by the rotating blade 13b. The foliage is cut when the rotary blade 13b passes so as to sandwich the lower part of the foliage. In addition, the small potatoes on the foliage are crushed by the cutting blade and do not harm the crops to be planted later. Further, since the rotating blade 13b is provided with the backing plate 13c, the cut piece is blown to the side by the backing plate 13c. In the foliage processing machine 1 of the present embodiment, the rotating blades 13b, which are one set each on the left and right, are rotated in different directions, so that the cut pieces fall between the two sets of rotating blades 13b, that is, between the ridges and the ridges. I'll let you go. In this way, the foliage is crushed in order from the bottom and accumulated between ridges. Therefore, the foliage can be efficiently treated without using pesticides, which is preferable from the viewpoint of food safety, and without the problem of pesticide residues in the soil.
