2. Description of the Related Art At present, for example, a long-potato harvesting machine equipped with a digging section consisting of a digging conveyor having a digging blade at its tip is used for harvesting long-potato. The yam harvester, in the soil,
With the digging blade positioned below the long potato, the end of the trench conveyor is inclined so that it approaches the ground level, and by advancing in that state, the digging blade lifts the long potato along with the soil and pulls it out. This is to dig up the picked potatoes along with the soil so that the conveyor conveys them to the field.

In order to achieve the above object, the present invention employs the following technical means. The technical means is to pick up the long potato N downstream of the dug portion 1 without damaging the long potato N dug up by the excavation portion 1 and without changing the posture of the worker M1 from near the ground level. This is the long-potato harvesting machine A provided with the supporting means 2 for lifting to a possible height. (Claim 1)

[0006] In the yam harvesting machine A of the present invention, the yam N is extracted by the excavation section 1 from the soil so that it rises together with the soil, and is supported by the soil up to the middle, and finally the soil is not supported and falls down. . That is, it is desirable that when the long potato N falls, it is placed on the support means 2 and lifted up as it is. However, since the direction in which the long potato N falls is not always constant, the worker M just before the long potato N falls.
It is preferable to adopt a configuration in which the long potato 2 is placed on the support means 1 while taking the long potato N, and in this case, the worker M2 changes the posture of the long potato N dug up by the excavation section 1. It is optimal to have a working unit 3 that can be moved to the support means 2 without having to. (Claim 2)

According to the support means 2 as described above, the potatoes N are placed on one of the support plates 21 located near the ground level, and the potatoes N are fully loaded on the support plate 21 and then the support plate 21 is lifted. Then, at the same time, the other support plate 22 located above is lowered to the ground level and the positions of both support plates are switched. Then, the potatoes N on the support plate 21 that have risen
Repeating the work of placing the potatoes N on the lowered support plate 22 while performing the above-mentioned work of picking up and switching the positions of both support plates again after the end of both works. In other words, with the support means 2 having this configuration, it is possible to perform the placing work and the picking-up work of the long potato N at the same time.

The excavation section 1 has a well-known structure having a excavation conveyor 12 on the rear side of the excavation blade 11, so a detailed description thereof will be omitted. 11
Is located below the chopsticks N, and the Horigami conveyor 1
The digging blade 11 lifts the potatoes N together with the soil by inclining the terminal end of 2 so as to reach the ground level and advancing it with a towing vehicle (not shown) in this state. Also, the digging blade 11 and the Horigami conveyor 1
The angle adjustment operation 2 and the operation of the trench conveyor 12 are performed by transmitting the power of the towing vehicle. Reference numeral 5 is a long potato storage unit, which is placed on a carrier C1 that is towed by a towing vehicle (not shown) and runs in parallel with the long potato harvester A. Although the carrier C1 is a separate body from the potato harvester A in the present embodiment, and is shown to be individually towed by each towing vehicle, for example, the carrier C1 is the potato harvester. It may be integrated with A via the frame,
In this case, it becomes a long potato harvester equipped with a carrier.

More specifically, FIGS. 2 (a) to 2 (c)
2, the link rod 61 (the front side in FIG. 2B) pivotally supports the front side of the support plates (the side of the excavation portion 1), and the link rod 62 is the side face of both support plates. The rear side is pivotally supported to support both support plates at substantially diagonal positions.
As a result, rotation of both support plates with respect to the support shaft S is suppressed, and both support plates are always held horizontally. The support shafts of the link rods 61 and 62 with respect to the both support plates support the support shaft S so that the support shafts are always kept horizontal even if the height positions of the link rods 61 and 62 vary with the rotation. The support plate is fitted with play. Link rod 61,6
2 are rotatably supported at their centers by rotating shafts S1 and S2, respectively, and by rotating the rotating shaft S1 by the power transmission of a motor or a tow vehicle (not shown), the link rod 61 is rotated. The rotation is the rotation of the link rod 62 via both support plates, and the rotation of the link rods 61, 62 switches the positions of both support plates.
The rotation of the rotary shaft S1 is automatically controlled by, for example, controlling the workers M1 and M2 by an ON / OFF switch (not shown) or detecting the weight of the potatoes placed on both support plates. It may be controlled to rotate.

The long-potato harvesting machine A constructed as described above is capable of moving the long-potato N, which is dug up by the excavation machine 1 while moving forward with a towing vehicle,
The worker M1 sitting on the working unit 3 before falling over
Is removed and placed on the support plate 21. (FIG. 3A) When the potatoes N are loaded on the support plate 21, the link mechanism 6 operates to raise the support plate 21 and lower the support plate 22 to switch the positions of both support plates. At this time, FIG.
3B through FIG. 3B and FIG. 3C again to the state of FIG. 3A, the support plate 22 is at the original position of the support plate 21, and the support plate 21 is at the position of the original support plate 22. . Then, the worker M2 standing on the working unit 4 removes the soil of the potatoes N on the support plate 21 that has risen, and the worker M3 near the right side of the support plate 21 picks up the potatoes N and puts them in parallel with the potato harvester A. It is stored in the long potato storage section 5 on the traveling carrier C1. At this time, the worker M1 sitting on the working unit 3 is simultaneously performing the work of pulling out the potatoes N and placing them on the support plate 22, and the support plates 22 are fully loaded with the potatoes N and 21
When all of the upper potatoes N are stored in the potato storage portion 5, the support plate 21 is lifted by the operation of the link mechanism 6 to move the support plate 2
2 is lowered and the positions of both support plates are switched again. This process is repeated to harvest long potato N.
