[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4 The utility model provides a technical solution: a fruit picking robot, comprising:

[0027] Base 1;

[0028] An adjusting member 2 is provided on one side of the base 1;

[0029] A clamping member 3 for picking fruits is provided on one side of the adjusting member 2;

[0030] The clamping member 3 includes a mounting plate 31 disposed on one side of the adjusting member 2. A plate body 32 is fixedly mounted on one side of the mounting plate 31. Three slots 33 are formed inside the plate body 32. Threaded rods 34 are rotatably mounted inside the three slots 33. Clamping seats 35 are threadedly mounted on the surfaces of the three threaded rods 34.

[0031] A driving member 30 for synchronously driving the three clamping seats 35 is provided inside the mounting plate 31 .

[0032] The driving member 30 includes a motor 301 embedded in a mounting plate 31. A toothed disc 302 is mounted on the output end of the motor 301. Gears 303 are fixedly mounted on the surfaces of the three threaded rods 34. One side of the three gears 303 meshes with the teeth on the surface of the toothed disc 302.

[0033] In this embodiment, the starting motor 301 drives the toothed disc 302 to rotate, and the toothed disc 302 drives the three gears 303 to rotate synchronously, thereby controlling the rotation of the three threaded rods 34, and realizing the three clamping seats 35 approaching or moving away from each other, which is the same as clamping and picking fruits. The adjacent sides of the three clamping seats 35 are provided with adhesive strips 6 for protecting the surface of the fruit and enhancing friction. The surface of the fruit will fit on the adsorption seat 51, and the starting cylinder 55 can drive the sealing piston 54 to move in the cylinder 53. Since the sealing piston 54 fits tightly against the inner wall of the cylinder 53, the air in the adsorption hole 52 is sucked away, and one side of the adsorption hole 52 is blocked by the fruit, thereby generating negative pressure to adsorb the fruit.

[0034] The three troughs 33 are all fixedly mounted with a protective plate 4, and the surface of the protective plate 4 is slidably mounted on the inside of the clamping seat 35;

[0035] Specifically, the protective plate 4 is provided to protect the threaded rod 34 and the gear 303 to prevent branches from being inserted into the groove 33 and causing an impact, and to assist the clamping seat 35 in moving more stably.

[0036] A suction member 5 for assisting in the suction of fruit is mounted on one side of the disc body 32. The suction member 5 comprises a suction seat 51 fixedly mounted at the axis of the disc body 32. A suction hole 52 is defined within the suction seat 51. The suction hole 52 is connected to a cylinder 53. A sealing piston 54 is disposed within the cylinder 53. A cylinder 55 connected to the sealing piston 54 is mounted on one side of the disc body 32.

[0037] Furthermore, the surface of the fruit will fit on the adsorption seat 51, and the starting cylinder 55 can drive the sealing piston 54 to move in the cylinder 53. Since the sealing piston 54 fits tightly against the inner wall of the cylinder 53, the air in the adsorption hole 52 is sucked away, and one side of the adsorption hole 52 is blocked by the fruit, thereby generating negative pressure to adsorb the fruit.

[0038] One side of the adsorption seat 51 is provided with an adhesive layer portion, and the adjacent sides of the three clamping seats 35 are all installed with adhesive strips 6;

[0039] The adhesive layer on one side of the adsorption seat 51 can fit more closely to the surface of the fruit, ensuring that the surface of the fruit is blocked at the adsorption hole 52 as much as possible.

[0040] One side of the three clamping seats 35 is integrally machined with a slider 7, and one side of the mounting plate 31 is provided with a slide groove 8 for the slider 7 to slide;

[0041] In order to enhance the stability of the movement of the clamping seat 35 , the movement of the clamping seat 35 will drive the slider 7 to slide and adjust in the sliding groove 8 .

[0042] The adjusting member 2 includes a lower bracket 21 fixedly mounted on the top of the base 1, an upper bracket 22 is rotatably mounted on the top of the lower bracket 21, one end of the upper bracket 22 is fixedly mounted on the surface of the mounting plate 31, and two electric push rods 23 are hinged between the upper bracket 22 and the lower bracket 21;

[0043] It is worth noting that the two electric push rods 23 are synchronous push rods. When the electric push rods 23 are started, the upper bracket 22 is driven to rotate, thereby realizing the rotation of the mounting plate 31.

[0044] The device starts the motor 301 to drive the toothed disc 302 to rotate, and the toothed disc 302 drives the three gears 303 to rotate synchronously, thereby controlling the rotation of the three threaded rods 34 to achieve the three clamping seats 35 approaching or moving away from each other, which is the same as clamping and picking fruits. The adjacent sides of the three clamping seats 35 are provided with adhesive strips 6 for protecting the surface of the fruit and enhancing the friction. The surface of the fruit will fit on the adsorption seat 51. The starting cylinder 55 can drive the sealing piston 54 to move in the cylinder 53. Since the sealing piston 54 fits tightly against the inner wall of the cylinder 53, the air in the adsorption hole 52 is sucked away, and one side of the adsorption hole 52 is blocked by the fruit, thereby generating negative pressure to adsorb the fruit.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
