Then, in connection with the movement of the airframe, the peanut 1
The lower part of the leaf stem portion 5 is guided by a leaf guide plate 23, while the beans 17 in the ground are dug up by a dug-up blade 8. In the digging work, the digging blade 8 is provided in an inverted C-shape in plan view in the forward direction from the left end and the right end toward the rear center, so that the peanuts 15 Blade 8 and blade 8
The soil, roots, dust and the like are removed from the gap A, and the resistance is small, the followability to the ridge is improved, and the efficiency of the harvesting operation can be improved.

When the leaf stem portion 2 extends to the left or right, or both sides, the left leaf guide plate 23 or the right leaf stem guide plate 23 or the leaf stem guide plates 23 located on both left and right sides. Thus, the conveyor 9 can smoothly take over and transport the excavated peanuts 15 one by one. The peanuts 15 taken over by the conveyor 9 move most of the beans 17 on the lower side toward the rear upper side, which is the conveying direction, in a posture in which the beans 17 are placed on the conveying surface. It is discharged to the conveyor 30. In this transporting operation, if the peanuts are falling down, the worker near the second conveyor 30 may adjust the posture so that the beans 17 are located on the lower side.

Peanuts 1 dug up by the conveyor 9
5 can be attached to the groundnuts 15 or the soil and sand lifted together with the groundnuts 15 can be dropped downward, so that the work in the working section can be performed in a hygienic manner and the adhesion to the beans 3 can be performed. Can be prevented. When the wheels 21 are along the ridges and the aircraft moves on a substantially predetermined course, the seat 25 is changed so as to face the second conveyor 30 and the driver himself is transported by the transport conveyor 9. The peanuts 15 that have been used can also be handled.

Thereafter, the groundnuts 15 conveyed rearward by the second conveyor 30 are moved from the end of conveyance to the starter
After moving on to 51, it slides down along the slope, and is then received by the numerous projections 46 and rides on the reversing device 45. Subsequently, since the reversing tool 45 rotates rearward (in the direction of the arrow) due to the weight of the peanuts 15, when it falls into the field, the leaf stem 16
Touches the ground, and the beans 17 are located on the upper side. The starter 51 can adjust the guide speed of the peanuts 15 by changing the length and the inclination angle in the front-rear direction.
The adaptability of conditions such as humidity and size of 5 can be improved.

Therefore, since the beans 17 which were underground are located at a position higher than the ground, sunlight and wind are good, and drying unevenness can be prevented, and drying of the beans 17 can be accelerated to improve the efficiency of the harvesting operation. Also, even if it rains after the peanuts 15 are discharged to the field, the water falls to the ground side, so that the beans 17 are immersed in the water and the humidity is not increased, so that the drying can be quickened.

In addition, since the reversing tool 45 is provided at a position slightly higher than the height of the peanuts 15 from the surface of the field to be discharged, the peanuts 15 can be reversed and the beans can be prevented from falling off. Further, by changing the length of the coil spring 48 by operating the butterfly nut 50, the load required for turning the reversing tool 45 can be adjusted. For example, it is possible to cope with the dry state and the weight of the peanuts 15, Improve the adaptability of harvesting work.

The protrusion 39 has a height from the outer surface of the reversing tool 38 of about 20 mm and a size (thickness) in the width direction of 10 m.
m, so peanuts 1 that fall while sliding
And the fall when ejected by the reversing tool 38 is also improved. Then, by operating the shift switch 41,
If the transport speed of the second conveyor 30 is reduced, the time of transport by the second conveyor 30 can be lengthened. Therefore, the second conveyor 30 can be used also as a sorting work place, for example, it is possible to determine the quality of the harvested crop, whether it is defective or defective, or to remove the outer leaves of the crop.

When the speed of the second conveyor 30 is adjusted to be higher than the speed of the conveyor 9 by operating the speed change switch 41, the interval between the crops conveyed by the conveyor 9 is increased. 30 allows the spacing to be increased. Therefore, when the harvested crop is peanut 15, the front and rear peanuts 15 approach,
The peanuts sent later do not get on the inverted peanuts and hinder the reversing action, so that the beans 17 can be discharged to the ground with the beans 17 on the upper side and the leaf stems 16 on the lower side.

By operating the shift switch 40, the transport speed of the transport conveyor 9 can also be changed, so that the adaptability to the type of crop to be harvested or the condition (for example, size) of the crop can be improved. Moreover, the shift switch 4
Since 0 and 41 are provided near the control section S and the second conveyor 30, the operator can adjust the transport speed of the transport conveyor 9 and the second conveyor 30, as a matter of course. The shift operation can be performed quickly even when working in the vicinity.
