Next, the power transmission mechanism of the processing section 2 will be explained in detail.

In FIGS. 3, 4, and 5, 58 is a forward rotation pulley attached to the forward rotation shaft 59 of the gear box 5/I, and 60 is the reverse rotation shaft 61 of the gear box 5/I.
Nitori (= l digit reversing pulley, each pulley 58.6

7 and 68 are connected to a forward/reverse rotation operating lever 71 disposed in the cockpit 55 via respective connectors 69 and 70 such as wires.

As shown in FIG. 5, the clutch mechanism 67 has a tension pulley 72, which is supported by an arm 74 swingably supported by a support member 73 so as to be movable up and down, and is connected to the arm 74. By pulling the connector 69, the tension pulley 72 can be rotated downward.

Note that the arm 74 is forced upward (=l) by the ammunition 75.

The clutch mechanism 68 has a tension pulley 76, as shown in FIG.
is supported to be able to rise and fall by an arm 78 that is swingably supported by a support member 77, and by pulling the connector 70 connected to this arm 78, the tension pulley 76
It is configured so that it can be rotated so as to raise it. Note that the arm 78 is forced downward by the ammunition 79.

A counter pulley 80 is fixed to the counter shaft 62, and is connected via a belt 83 between a pulley 81 fixed to the lower chopping roll shaft 43 and a pulley 82 fixed to the lower roll shaft 39. . A gear 84 is fixed to the lower chopping roll shaft 43 and meshes with a gear 85 fixed to the upper chopping roll shaft 42. 87-6 is a gear fixed to the lower roll 1llllll 39,
It meshes with a gear 87 fixed to the upper roll shaft 38. 88 is a pulley with a different diameter fixed to the lower roll shaft 39; a pulley 89 fixed to the lower defoliating roll shaft 35; Tension pulley90. A pulley 91 fixed to the lower roll shaft 31 and a pulley 93 fixed to the counter shaft 92
They are connected via a belt 94 between them. A gear 95 is fixed to the counter shaft 92 and meshes with a gear 96 fixed to the upper roll shaft 30. A pulley 97 is fixed to the upper roll shaft 30, and a pulley 99 is fixed to the reaping drive shaft 98. A belt 10 is placed between a counter pulley 100° 101 and a pulley 102 fixed to the roll shaft 57.
Connected via 3.

104 is a pulley of different diameter fixed to the reaping drive shaft 98;
It is connected via a belt 106 to a pulley 105 fixed to the upper defoliating roll shaft 34.

In the above configuration, when each rotating part is driven by the prime mover 53 and the forward/reverse rotation operation lever 71 is operated to the forward rotation side, a clutch mechanism 678- is connected between the forward rotation pulley 58 and the forward rotation counter pulley 63 via the coupling device 69. The tension of the stretched bell 1-65 is increased, forward rotation is transmitted to the counter shaft 62, and each rotating part of the processing section 4 is driven. In this state, the driving device 11 positions the lifting device 8 on the side where the planted stem is inverted, for example, the left side, to the appropriate working position, and the top is cut in accordance with the 9♀ position of the planted stem. The height position of the device 9 is adjusted by the drive device 16, and the reaping processing cylinder 17 is lowered by the drive device 20, and the reaping device 1 of the reaping device 21 is moved.
After adjusting the position to the cutting height position, move the machine forward and start work.

Then, the fallen planted stem is lifted up by the pulling device 8, and the top head of the lifted stem is scraped into the scraping device 12 of the top cut device 9 and cut off by the rotary cutting blade 13. At the same time, the root portion is harvested from the soil by the reaping device 1. The cut stem trunk is lifted up while being tilted forward by the lifting device 24, and is held by the scraping body 25 and sent to the processing section 4 of the cutting processing barrel 17. The stem t sent to the processing section 4? The primary feeding device 26 connects the receiver, and the primary feeding device 26 conveys the stem along the trunk conveying path 1. Then, dead leaves and the like are removed during the process of being transported through the rotary IItx confectionery device 2, and further fed into the rotary cutting device 3 by the secondary feeding device 27, where it is cut into a predetermined length, usually 30 cm Pi! i) is shredded and discharged into the discharge space 46. In the discharge space 46, the suction air generated by the rotation of the suction fan 50 selects foreign substances such as dead leaves mixed in the shredded stem trunk and discharges them from the suction air cylinder 49 to the outside of the machine. . The wind-selected shredded stems fall onto the starting end of the lifting conveyor 52, are lifted rearward and upwardly by the lifting conveyor 52, and are discharged from the machine from the terminal end, for example, at the rear of the aircraft. It is sent into a storage bag or the like that is towed by a person and stored there.

In the reaping and harvesting work carried out in this way,
When a large amount of stems are fed into the processing section 4 at once, an excessive load is applied to the rotary shredding device 3 and the like, causing the prime mover 53 to stop, and the processing section 4 may be clogged with stems. In such a case, when the forward/reverse operation lever 71 located on the forward rotation side is operated to the reverse side, the clutch mechanism 67 is released and the forward rotation pulley 58 is activated by a bell stretched between the forward rotation counter pulleys 63. 1-65 is relaxed and the power to the counter pulley 63 for forward rotation is cut off, and the clutch mechanism 68 acts via the connector 70 to connect the pulley 59 for reverse rotation and the counter pulley 64 for reverse rotation. The tension of the belt 66 stretched on the counter shaft 62 is increased.
What happens when reverse rotation is transmitted? In this state, the motor 1f
When the i53 is restarted, the reverse rotation of the power from the prime mover 53 is transmitted to the counter shaft 62 via the reversing pulley 59, the belt 66, and the reversing counter pulley 64, and the upper and lower pair of chopping rolls 40° 41a3 of the processing section 4
Then, the pair of upper and lower defoliating rolls 32 and 33 rotate in the opposite direction of the arrow in FIG. This chopping roll 40
．． 41 and the defoliating rolls 32 and 33 are rotated in the opposite direction, thereby chopping 11-roll 40. /11 The stems that are stuck between
7 to the supply port side, and the blockage is released. At this time, the pair of upper and lower defoliating rolls 32 and 33 rotating in the opposite direction exerts a tensile action on the stem trunk, so that the blockage is effectively cleared.

Also, the pair of upper and lower leaf removal rolls 32 and 33 rotate in the opposite direction. The thick layer thickness is loosened and evened out so that an effective defoliation and cutting action can be carried out when the operation is resumed.

As is clear from the above, according to the configuration of the present invention, when the leaves fall off while the stump harvested by the reaping device is transferred, and furthermore, when the stump becomes clogged in the process of cutting into a predetermined size, at least The rotary defoliation layer and the rotary cutting device can be reversed, so that the cutting device can be easily and easily removed from clogged stems. In particular, the reverse drive of the rotary defoliation device exerts a tensile action on the stem, which pulls out the stem that is clogging the rotary cutting device, making it possible to effectively clear the blockage. In addition, since the layer thickness of the clogged stem is loosened and made uniform by the reverse drive of the defoliating device, effective defoliating and cutting operations can be carried out when work is resumed.

It should be noted that the present invention is not limited to the above-described embodiments, and the present invention can be practiced in other forms than the above-described embodiments.
