Not configured.

Next, the operation of the above example will be described in detail. First, when traveling on the road, the operator rides in the regular driver's seat 6 and drives and operates in the same manner as tractor operation, such as cabbage and lettuce. Get into the field where the spherical vegetables are grown. Next, in the vegetable harvesting operation, the operator descends from the driver's seat 6 to the field, sits down on the harvesting seat 34, and packs the harvested vegetables into the cart 18 by the operator.
And start harvesting.

At this time, the required number of empty carts are mounted on the carrier 18 and the spare table 52. Next, the worker sitting on the harvesting seat 34 adjusts and sets the working speed, the transport speed of the conveyor device 25, and the like by using various control tools and various switches provided on the control panel 42, and runs the traveling vehicle body 1, The harvesting seat 34 is located on the ridge where the vegetables grow, and is operated so that the harvesting operation is easy. That is, the operator and the harvester operate the various control devices and operating devices while operating them. The operator and the harvester are the harvesting seats 34
While rooting at the speed of the traveling vehicle body 1 while sitting on the ground, the root is cut off while pulling out a spherical vegetable with a kitchen knife or the like in hand, and the vegetable is placed on the front conveyor device 25.

Vegetables such as cabbage and lettuce placed on the conveyor device 25 are transported rearward and upward, and are discharged from the terminal end thereof into the crop mounting table 48 to be temporarily stored. Therefore, an operator boarding the carrier 18 takes out the vegetables from the harvesting table 48 and stores them in the cardboard box provided on the work table 51 while removing the wounds and dead leaves of the vegetables on the work table 51. Unloading carrier 18
Stack them while organizing them on top.

When the vegetable harvesting operation is performed as described above and the vehicle turns and turns near the ridge, the harvesting seat 3
The harvester seated on the seat 4 operates the lever 47 to stop the electric motor 30 and switches the motor 37 by the switch SW2.
To move the seat 34 and the front of the conveyor device 25 slightly upward, and furthermore, switch the hydraulic switching valve 14 with the switch SW1 to raise the crop transport trolley 16 via the lifting mechanism 9, and then raise the lever 46. Operate to operate the steering wheel and turn to the side to be turned. After the turn, the carrier 16 is lowered and the seat 34 and the conveyor 25 are lowered, and the belt conveyor 25 is driven again to perform the harvesting operation. The working speed is implemented by operating the throttle of the engine and operating the lever 47.

During this operation, when the front side of the conveyor device 25 is adjusted up and down or raised during turning, the crop mounting table 48 is automatically rotated and always harvested and transferred by the conveyor device 25. The harvested vegetables are reliably discharged into the harvested table 48 on the end side. Therefore, it does not happen that the harvested vegetables are unexpectedly dropped and damaged from the transfer end side of the conveyor device 25.

Since the front side of the conveyor device 25 is received by the elevating device 33 provided at the front portion of the traveling vehicle body 1, the front portion of the conveyor device 25 can be freely adjusted up and down, and the type of the crop, the growing state, or the operation can be controlled. Can be adjusted to the appropriate height according to the bamboo of the body of the worker and the harvester, and the adjustment can be done easily at hand. Since the rear portion of the conveyor device 25 is provided so as to be freely refracted with respect to the transport carriage 16, the conveyor device 25
Truck 16 at the time of vertical adjustment or turning of the front side of the vehicle
, And can smoothly operate.

[0023]

According to the present invention, the vegetable harvest seat 3
In step 4, the carrier trolley 16 can be raised and lowered while sitting on the seat 34 while turning while harvesting the vegetables in the field, and furthermore, the vegetable harvest can be placed on the conveyor device 25 while maneuvering. And can be automatically and reliably accommodated in the crop placing frame 48, so that another worker who rides on the transport trolley can sort into containers such as cardboard boxes with sufficient margin. It has a function and effect that can be accommodated.
