Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-4 This utility model provides a non-destructive loquat fruit harvesting mechanical claw, including an outer block 9; a rotating rod 14 is rotatably connected to one side of the outer block 9; an outer ring 15 is fixedly connected to one side of the rotating rod 14; a rotating rod 17 is rotatably connected to the inner wall of the outer ring 15; a collecting ring 16 is fixedly connected between the rotating rods 17; a collection net 18 is fixedly connected to the bottom of the collecting ring 16; a top block 10 is fixedly connected to the top of the outer block 9; and a connecting rod 13 is fixedly connected to the side of the top block 10. During operation, as the outer block 9 tilts, the outer ring 15 can rotate freely to one side of the outer block 9, and the collecting ring 16 can rotate freely within the outer ring 15 using the rotating rod 17. This ensures that the collection net 18 remains perpendicular to the ground when the mechanical claw is at a certain tilt angle, facilitating the collection of loquats.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, a clamping rail 11 is fixedly connected to one end of the connecting rod 13; a video monitor 19 is mounted on the top of the clamping rail 11; a servo motor 12 is mounted on the side of the clamping rail 11; and a double-threaded screw 20 is fixedly connected to the output end of the servo motor 12. During operation, starting the servo motor 12 causes the double-threaded screw 20, which has a mirrored thread along its middle section, to rotate, while the video monitor 19 collects video information about the loquat fruit.

[0028] Furthermore, such as Figure 4 As shown, a slider 21 is threadedly connected to the outer wall of the double-threaded screw 20; a cutting clamp 22 is fixedly connected to the side of the slider 21. During operation, the rotation of the double-threaded screw 20 allows the slider 21 to slide on the inner wall of the clamping track 11, while simultaneously causing the cutting clamp 22 to move closer together and cut the stem of the fruit.

[0029] Furthermore, such as Figure 1 As shown, an internal slide rod 7 is fixedly connected to the bottom of the external block 9; an adjustment hole 8 is provided on the inner surface of the internal slide rod 7. During operation, the internal slide rod 7, in conjunction with the adjustment hole 8, can play a role in limiting and fixing the position.

[0030] Furthermore, such as Figure 1 As shown, an outer rod 1 is slidably connected to the outer wall of the built-in slide rod 7; a fixed body 3 is fixedly connected to the top of the outer rod 1. During operation, the built-in slide rod 7 slides inside the outer rod 1, thereby achieving the function of adjusting the length of the device.

[0031] Furthermore, such as Figure 1 As shown, a handle 2 is fixedly connected to the bottom of the external rod 1; a display screen 6 is installed on the side of the fixed body 3. During operation, the video captured by the video monitor 19 will be displayed on the display screen 6, which will make it easier for users to observe the loquat fruit and facilitate the harvesting of loquats.

[0032] Furthermore, such as Figure 1 As shown, the fixing body 3 is connected to a fixing screw 4 via a built-in slide rod 7; both ends of the fixing screw 4 are threaded with hexagonal nuts 5. During operation, the fixing screw 4 is inserted into the fixing body 3 and the built-in slide rod 7, and then the fixing hexagonal nuts 5 are rotated to limit the position.

[0033] Working principle: During the tilting process of the outer block 9, the outer ring 15 can rotate freely on one side of the outer block 9. Simultaneously, the collection ring 16 can rotate freely within the outer ring 15 using the rotating rod 17. This ensures that the mechanical claw, at a certain tilt angle, keeps the collection net 18 perpendicular to the ground, facilitating the collection of loquats. When the servo motor 12 is started, the double-threaded screw 20, which has a mirrored thread along its central section, rotates. Simultaneously, the video monitor 19 collects video information about the loquat fruit. The rotation of 0 allows the slider 21 to slide on the inner wall of the clamping track 11, while the cutting pliers 22 move closer together to cut the stem of the fruit. The built-in slide rod 7, in conjunction with the adjustment hole 8, can play a role in limiting and fixing. The built-in slide rod 7 slides inside the outer rod 1, thereby realizing the function of adjusting the length of the device. The video captured by the video monitor 19 will be displayed on the display screen 6, which makes it convenient for users to observe the loquat fruit and facilitates the harvesting of loquat. The fixing screw 4 is inserted into the fixing body 3 and the built-in slide rod 7, and then the fixing hexagonal nut 5 is rotated to limit the movement.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
