Things.

The left and right stacking plates (23) can be switched between a horizontal posture and a standing posture, and accumulate foliage in a horizontal posture. In a device having a discharge mechanism, when the accumulation amount becomes constant, the posture is switched to the hanging posture by a manual operation or a mechanical automatic operation using the weight, and the discharge is discharged to the ground. Note that the postures of the left and right stacking plates (23) are switched alternately, and the rear end of the pinching transport device (10) is swung right and left in conjunction with the switching.

In addition, on the left and right of the front of the airframe (1), a weeding body (24) is provided for separating the foliage to be processed from the foliage to be processed, and a ridge is provided slightly behind the weeding body (24). A sled body (25) is provided on both hem surfaces to slide on the ground. Furthermore, the upper part of the pinching transport device (10) is covered with front and rear protective covers (26) and (27), and the rear protective cover (27) is provided with the endless chain (13) of the pinching transport device (10). ) Is swung right and left integrally with the rear part. The upper surface of the ridge is covered with a multi-film (28).

In order to pull out the foliage of the rhizome crop (A) with this foliage processing machine, the wheels (5) are driven by the engine (3).
To move the fuselage (1) forward along the ridge. Then, the foliage is scraped backward by the scraping device (9), pulled out by the pinching transport device (10), and transported to the stacking device (8). During this time, the roots are left underground.

When the foliage is pulled out, most of the root is stored in the soil due to the resistance of the soil and the action of the gauge foil (21), and some of the roots come up with the foliage. Dropping this is the trapping transport device (10)
A root drop guide rod (29) provided below the lower part. The root drop guide rod (29) is attached to the gauge wheel (2).
It consists of two bars arranged in parallel and attached to the inside of 1), and the foliage portion pulled out by the sandwiching conveying device (10) passes between these bars. Therefore,
If the foliage has a root, the root dropping guide rod (29) can reliably handle the foliage.

The foliage transported by the pinching transport device (10) is dropped onto the stacking plate (23) of the stacking device (8) which is in a horizontal position (the pinching transport device (1)).
0) The rear end is also swung to that side), and a predetermined amount is stored thereon. When the accumulated amount of the foliage reaches a certain level, the stacking plate (23) is manually or automatically switched to the hanging posture, and the foliage is discharged to the ground.

FIGS. 5 and 6 show a modified structure of a chain-type pinching and conveying device (10), in which one of the right and left is changed to an endless chain (13) to form a pinching body (30). The pinching body (30) is made of a rod material along the transport side surface of the other endless chain (13), holds the foliage with the endless chain (13), and feeds the foliage with the endless chain (13). Things. For this reason, the pinching body (30) is constantly pressed toward the endless chain (13) by the spring (30a). The straddling body (30) is divided into front and rear parts, and the middle part is bent and connected integrally by a flexible connecting pipe (31).
