The harvest box mount 35 is attached to the upper frame 10 of either the front or rear, depending on the position of the swivel chair 20.
Is mounted on the horizontal frame 10a.

A seat lift mechanism 40 is provided on the back surface of the mounting portion 35a of the harvest box mounting base 35. Hereinafter, the configuration of the seat lift mechanism 40 will be described with reference to FIG. FIG. 3A is a front view showing a portion of the seat lift mechanism, and FIG. 3B is a side view thereof.
A seat lifter arm support rod 41 extending in the lateral direction is provided on the back surface of the mounting portion 35a. A screw mechanism is provided at both ends of the seat lifter arm support rod 41, and a flat sheet lifter arm 43 is provided at each of these portions so as to extend obliquely downward. A height adjusting screw 46 is provided on the back surface of the mounting portion 35 a, and the height adjusting screw supports the seat lifter arm 43. That is, the seat lifter arm 43 is configured so that the height is adjusted by operating the height adjustment screw 46 about the seat lifter arm support rod 41 as a fulcrum. 41
, The horizontal spacing is adjusted.

Each seat lifter arm 43 has
A seat lifter 48 that vertically projects toward the ridge is provided. The sheet lifter 48 is formed in a rod or roller shape, and has a structure in which a sheet described later is easily slid. The sheet lifter 48 can be constituted by one to several sheets.

A field where a harvesting operation is performed is prepared in advance as shown in FIG. 4 so as to be suitable for the harvesting vehicle constructed as described above. Usually, two rows of strawberry seedlings are planted in one ridge. Then, as shown in the figure, a sheet 55 made of, for example, porous polyethylene or vinyl is laid from both sides of the ridge covered with the multi-film, and the sheets on both sides are connected with an adhesive tape 57 at predetermined intervals. . Perform this work before the strawberry harvest season. As shown in the figure, the strawberry grows on the sheet 55 so as to hang in a furrow.

Next, a strawberry harvesting operation using the harvesting vehicle will be described. First, the harvesting vehicle,
In a state of straddling one ridge, the left and right wheel portions are positioned so as to match the grooves of the ridge with strawberry fruits, and an operator sits on each swivel chair 20. In this case, the swivel chair 20 is arranged so as to face the direction in which the harvesting work vehicle advances. That is, in FIG. 1, the harvesting work vehicle is in a state of traveling to the right. In the above-mentioned seat lifter 48, the height and the lateral interval are adjusted in advance by the seat lifter arm support rod 41 and the height adjusting screw 46 according to the height and width of the ridge.

Then, the end portion of the sheet 55 covering the ridges is lifted and placed on the corresponding sheet lifter 48 as shown by the dotted line in FIG. By running the harvesting vehicle in this state, the strawberry fruit is lifted up and the sheet 55 is sequentially lifted to the height of the ridge. As described above, since the sheet lifter 48 is configured in a rod or roller shape, the sheet 55 can be stably lifted while the harvesting work vehicle is running. As the harvesting work vehicle moves along the groove of the ridge, the worker sitting on each swivel chair 20 picks the strawberry on the seat 55 lifted by the sheet lifter 48, and places the picked strawberry in front of him. Into the harvest box 30 at

In this way, the sheet 55 is laid on the mulch film covering the ridges, and the sheet lift mechanism attached to the harvesting work vehicle 1 lifts the strawberry fruits hanging between the ridges so that the three-dimensional structure is obtained. Strawberry fruits existing in different spaces can be spread two-dimensionally, which makes picking work easier and reduces the amount of leftover picking. In addition, by arranging the sheet 55, it is possible to prevent the fruit being cultivated from being stuffy. Furthermore, when using a machine that automatically harvests strawberries instead of picking them by hand, it is only necessary to harvest strawberries that spread two-dimensionally, so the picking mechanism can be easily configured. be able to.

The electric motor 6 and the wheel portions 2 described above are controlled in driving direction and rotation by a controller in a control box 50 placed on a mounting table provided in a substantially central portion of the upper frame 10. The ridge-back drive and the movement between the ridges are controlled according to a predetermined program.
