[0006]

Since the present invention is configured as described above, it has the following effects. Long-stalked vegetables such as spring onions are cultivated three to four times before harvesting to increase the softness, so that more softness is formed. The shape of the embankment is approximately Kamaboko. The roots of long-stem vegetables such as spring onions are located at a position considerably deeper than the top surface of the kamaboko-shaped top, and the surplus soil on the side of the embankment is removed by the side plate 2B attached to the front surface of the excavation claw 2A during excavation. The root of the long-stalk vegetable 20 and the like are excavated and excavated with the excavating claw 2A. The excavated long stalk vegetables 20 such as green onions and the remaining soil are in an unstable state, and fall down little by little by the inward guiding rod 19B as the machine frame 1A advances, and roll over on the fixed grid 2C. The overturned vegetables 20 such as the overturned green onions and the outer guiding rod 19A together with the earth and sand
To receive the foliage and guide backward. The belt 14 receives a leaf portion of a long stem vegetable such as green onion, picks it up, and feeds it to the transport section by running the belt. Long-stalked vegetables 20 such as long green onions that were dug up with earth and sand and overturned by the inward guide rod 19B.
In order to separate and pick up the earth and sand for forming the soft white part and pick it up and transfer it to the lower end of the conveying part 4 by intermittent vibration, the connecting beam 3C is fixed to the eccentric shafts 3B11 and 3B21 which rotate by receiving power from other parts and connected. Below the beam 3C, a notch 3E1 having a substantially U-shaped side surface is formed on the upper surface of the elongated plate via an arm 3D.
Is rotated by the rotation of the eccentric shafts 3B11 and 3B21. The middle position of the vertical movement of the rotary motion is slightly coincident with the arrangement position of the fixed grid 2C configured by arranging the excavation claw 2A and the rod 2C1 in the front-rear direction in parallel. When the eccentric shafts 3B11 and 3B21 rotate upward and backward,
Long stem vegetables 2 such as green onions rolled over with earth and sand on the upper surface of a fixed grid 2C constituted by arranging rods 2C1 in the front-rear direction in parallel.
The sediment 0 is separated from the earth and sand by the vibration caused by the rotational movement and the forward and backward movements of the feed plate 3E, and the long stem vegetables 20 such as green onions are picked up from behind the excavating claw 2A and transferred to the lower end of the transport unit 4 by intermittent vibration. You. Furthermore, the projection 4A1 is conveyed to the workbench 5B by a belt conveyor 4A in which a protrusion 4A1 is implanted on the surface of the pick-up conveyance section 4 in a direction perpendicular to the traveling direction. As a result, it is possible to automatically perform a complex operation such as excavation of a long stem vegetable such as a soft and easily damaged long onion, rollover guidance, separation of sediment, and transfer.
