By controlling the operation of the second electric push rod 57, it is convenient to perform a secondary adjustment on the extension amount of the picking claw 7, thereby facilitating the picking operation of the picking claw 7 at ultra-low and ultra-high positions. The auxiliary rod 59 is set so that the force at the position of the connecting box 58 acts on it, thereby reducing the force on the second electric push rod 57 and extending its service life.

[0024] The rotary adjustment seat 6 includes a servo motor 4 61 installed inside the connecting box 58.

By controlling the operation of the servo motor 4 61, it is convenient to rotate the picking claw 7, that is, the angle of the picking claw 7 can be adjusted, and it is also convenient to take the fruit from the fruit tree.

[0025] The picking claw 7 includes a fixing box 71, which is connected to the U-shaped connecting seat 62 through a connecting pin 65. A partition 72 is installed inside the fixing box 71, and a gear connecting seat 73 is installed inside one side of the partition 72. Two meshing gears are fixed inside the gear connecting seat 73 through two mounting shafts. Grabbing teeth 74 are installed at the bottom ends of the two gears. One of the two mounting shafts passes through and extends to the top of the partition 72 and is connected to a servo motor 5 75. The servo motor 5 75 works under the action of the gear connecting seat 73 to close and open the two grabbing teeth 74, thereby facilitating the picking and putting down of fruit trees.

A tension pressure sensor 79 is installed on the surface of the fixing plate 77 corresponding to the extension plate 76, and the tension pressure sensor 79 is connected to the fixing plate 77 through a spring 78; thereby, after picking, the operation of the servo motor 4 61 is controlled to make the grabbing teeth 74 horizontal. At this time, since the fruit is fixed inside the grabbing teeth 74, the grabbing teeth 74 can be driven to rotate with the connecting pin shaft 65 as the axis, thereby changing the measurement data of the tension pressure sensor 79, thereby facilitating the detection of the weight of the fruit, thereby facilitating the classification and processing of fruits of different weights.

[0027] Soft balls 710 are distributed on the corresponding surfaces of the two grabbing teeth 74, thereby avoiding rigid contact with the fruit, so that the fruit is not easily crushed when picking.

[0028] The air blowing structure 8 includes an air pump 83 installed on the side of the U-shaped connecting seat 62, and air outlets 81 are provided on the separated surfaces of the grab teeth 74. The air outlets 81 are connected to the air pump 83 through a conduit 82. By controlling the operation of the air blowing structure 8, wind is blown out at the position of the air outlet 81, thereby blowing the leaves around the fruit trees, thereby facilitating the image collector 64 to collect more accurate information.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
