FIG. 9 shows an example of the structure which enables adjustment of the vacuum suction force of the harvesting hand (5).
A plurality of air circulation holes (53) are formed on the outer peripheral surface of the hand, and a cylindrical shutter (54) for opening and closing the circulation holes (53) is slidably fitted to the outer periphery of the hand (5) and the hand (5 ) A fulcrum shaft (56) is attached to a bracket (55) fixed to
And the shutter (54) through the swing arm (57)
, And the shutter (5
4) is held open, while a shutter wire (59) having one end connected to the arm (57) is pulled by a shutter closing solenoid (60) against a spring (57) so that the shutter (54) flows through the hole. When it is slid to the (53) side, the shutter (54) covers the flow hole (53) and closes it.

Then, as shown in the flow chart of FIG. 10, when the visual sensor (8) detects that the harvesting hand (5) has approached within the predetermined harvesting range of the cherry tomatoes (A), the blower (39a). When the sensor (8) detects that the hand (5) approaches immediately before the tomato (A), the shutter (50) is closed and the suction body (17) is turned on. It adsorbs cherry tomatoes (A) with the maximum suction force, and the shutter (54) is provided while the hand (5) moves to the position of the tomato (A) to be harvested next within the harvesting range after suctioning.
By holding the blade open, the suction force of the hand (5) is weakened while the leaves are squeezed between the leaves to reach the next target, and leaves other than the target are attracted to the suction body (17). In addition, the tomatoes (A) taken into the conveying path (18) can be sufficiently conveyed without causing any troubles such as exerting a sufficient suction force on the tomatoes (A) to prevent the conveyance. In this case, the vacuum suction force can be adjusted steplessly by adjusting the opening / closing amount of the flow hole (53) by the shutter (54).

As is apparent from the above examples, according to the present invention, the cultivated crop (A) to be adsorbed to the suction port (17) of the harvesting hand (5) is passed through the vacuum suction transfer path (18) in the hand. In the harvester (4) configured to discharge to the outside of the discharge port (18b), a conveyance sensor (42) for detecting the conveyed crop (A) on the conveyance path (18), and the discharge port (18).
a discharge shutter (44) for opening and closing b), and the discharge shutter (4) is detected based on the detection of the conveyance sensor (42).
Since the opening / closing control of 4) is performed, for example, when the conveyance sensor (42) detects the conveyance of a crop in the conveyance path (18), before and after the crop (A) is discharged from the discharge port (18b). The discharge port (18b) is opened only for a certain period of time, and no suction force is required from harvesting the crop (A) to harvesting the next crop (A). It is possible to carry out the above, and there is a remarkable effect such that the harvesting work using this vacuum suction force can be made stable and favorable.
