Example 1:

[0046] For reference Figures 1 to 6 The present invention provides an intelligent fruit sorting machine based on machine vision, including a main body 1 for accommodating and sorting fruit.

[0050] In a preferred embodiment, the visual inspection camera 209 is positioned above the middle of the conveyor belt 203, and the lower surface of the U-shaped plate 208 is attached to the conveyor belt 203.

[0051] It should be noted that the visual inspection camera 209 is connected to the display screen, which facilitates real-time differentiation of the sorting status of large, medium and small fruits. Example 2:

[0052] Based on Example 1, in order to further improve the convenience of fruit sorting, a feeding structure is provided on the main body 1;

[0053] As a preferred embodiment, the feeding structure includes a hopper 301 arranged on one side of the main body 1 for conveying fruit onto the conveyor belt 203.

[0054] In a preferred embodiment, the feeding structure further includes: a limiting groove 303, which is formed and arranged on one side of the main body 1 to limit the discharge hopper 301, and the discharge hopper 301 is slidably connected to the limiting groove 303; a slot 302, which is formed and arranged on the discharge hopper 301 to fix the discharge hopper 301; a locking plate 304, which is arranged on the main body 1 to fix the discharge hopper 301, and the locking plate 304 is engaged with the slot 302; and a sliding rod 30. 6. A plate 304 is used to move the plate 304, and the plate 304 is fixedly arranged at one end of the slide rod 306; a fixed plate 305 is fixedly arranged on the upper surface of the main body 1 to support the slide rod 306, and the slide rod 306 is slidably connected to the fixed plate 305; a spring 307 is fixedly arranged at one end on one side of the plate 304 and at the other end on the fixed plate 305, and is used to keep the plate 304 locked in the slot 302 by the rebound action of the spring 307.

[0055] It should be noted that the limiting groove 303 is T-shaped, and the shape of one side of the feeding hopper 301 is T-shaped to fit the limiting groove 303;

[0056] In a preferred embodiment, the slide bar 306 extends through the fixed plate 305. Example 3:

[0057] Based on Example 2, in order to further improve the convenience of fruit sorting, the main body 1 is provided with a discharge component;

[0058] In a preferred embodiment, the discharge component includes a discharge pipe 401 arranged on one side of the main body 1 for discharging the sorted fruit;

[0059] It should be noted that the discharge pipe 401 is set at an angle;

[0060] In a preferred embodiment, the discharge component further includes: a through hole 402, which is provided on the side of the main body 1 away from the U-shaped plate 208, for conveying sorted fruits into the discharge pipe 401; a threaded groove 403, which is provided on one side of the main body 1, for fixing the discharge pipe 401; and a bolt 404, which is threadedly connected to the discharge pipe 401 for fixing the discharge pipe 401, with one end of the bolt 404 threadedly connected to the threaded groove 403.

[0061] It should be noted that the discharge pipe 401 is connected to the through hole 402;

[0062] As a preferred embodiment, bolt 404 passes through discharge pipe 401.

[0063] Working principle: In use, first pull the slide bar 306 to one side to slide it on the fixed plate 305. The slide bar 306 drives the clamping plate 304 to move and compresses the spring 307. Then, the feeding hopper 301 is engaged with the limiting groove 303. Then, release the slide bar 306. The spring 307 rebounds, causing the clamping plate 304 to engage with the clamping groove 302 to fix the feeding hopper 301. This facilitates the assembly of the feeding hopper 301 by the user when sorting fruits. When not in use, disassemble it according to the above steps, which facilitates subsequent transportation. The operation is simple. The discharge pipe 401 is connected to the through hole 402 on the main body 1 via a bolt 404 threaded connection to the threaded groove 403. The discharge pipe 401 is also connected to the main body 1 via bolt 404, facilitating subsequent disassembly and reducing the space occupied by the device during transportation. Then, the motor 201 is turned on, driving the first conveyor wheel 202 to rotate on the main body 1. The first conveyor wheel 202, in conjunction with the second conveyor wheel 204 rotating on the main body 1, drives the conveyor belt 203 to rotate. Fruit is then placed on the feeding hopper 301, and the tilt of the feeding hopper 301 sets the fruit to fall onto the conveyor belt. On the conveyor belt 203, the rotation of the conveyor belt 203 drives the fruit to move at a uniform speed. When the fruit passes through the two sets of guide blocks 205, the two sets of guide blocks 205 help to center the fruit on the conveyor belt 203. When the fruit passes under the vision inspection camera 209, the vision inspection camera 209 captures the image of the fruit on the conveyor belt 203 to detect different individuals. When the vision inspection camera 209 detects the fruit of the desired individual, it transmits the data to the controller. The controller then controls the electric push rod 207 to open. The U-shaped plate 208 pushes the fruit on the conveyor belt 203 onto the through hole 402, where it falls onto the discharge pipe 401 for centralized collection. After the desired individual fruits are removed, the controller controls the electric push rod 207 to retract the U-shaped plate 208 to await the next round of operation. Other individual fruits are transported to the discharge hopper 206 by the rotation of the conveyor belt 203 for centralized collection, thereby reducing the physical labor consumed during manual sorting. Furthermore, the visual inspection camera 209 inspects the fruits, improving the sorting accuracy.

[0064] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments disclosed herein. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0065] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
