[0032] In embodiment 1, a tangerine peel screening mechanism for preliminary screening is provided. During the conveying process of tangerine peel, an image recognition mechanism 2 is installed above the conveyor belt 1. The image recognition mechanism 2 is used to obtain images of the surface of the tangerine peel in real time, and an external computer is used to process the images and recognize in real time whether there are cracks or mildew spots on the surface.

After the delay, the tangerine peel to be sprayed just moves to the air jet port 301. The spray mechanism 4 is started once to spray and clean the tangerine peel in the column to be processed. The column of tangerine peel is blown out from the air outlet 302 by high-speed gas. The tangerine peel after being blown out is recovered by the collection mechanism 6 for manual re-inspection and recycling. The spray mechanism 4 is closed after running once, waiting for the delayed start signal. By this method, the tangerine peel with cracks or mildew spots on the surface can be collected and processed first in the process of processing large batches of tangerine peel, so as to ensure the quality of most of the remaining tangerine peel and reduce the workload of subsequent manual quality inspection.

[0033] As a preferred embodiment 2, the tangerine peel is spread on the conveyor belt 1 with the outer skin of the tangerine peel facing upward, so that the image recognition mechanism can easily identify mold spots or cracks on the outer skin.

[0034] As a preferred embodiment 3, the image recognition mechanism 2 includes a camera mounting frame 201 disposed above the conveyor belt 1, and the two ends of the frame are respectively fixed to the two sides of the conveyor belt 1, and the conveyor belt 1 passes through the camera mounting frame 201. A mounting opening is provided in the middle of the top of the camera mounting frame 201, and an image recognition camera 202 is detachably mounted in the mounting opening.

[0036] Example 3 provides the specific structure of the spraying mechanism 4, in which the compressed air source for one injection is provided by the air compressor 401, the solenoid valve 403 controls the connection of the connecting air pipe 402, and finally the compressed air source is sprayed out from the nozzle 404, and the injection direction is pointed from the nozzle 301 to the air outlet 402, and the fixed base 405 is used to limit the installation of the nozzle 404 to ensure the direction of the injection.

[0037] As a preferred embodiment 4, the fixed base 405 includes a T-shaped mounting base 4051, which is detachably fixed to the side of the fixed frame of the conveyor belt 1 by fasteners, and a limit seat 4052 is provided at the bottom of the mounting base 4051.

[0039] As a preferred embodiment 5, the air compressor 401 is arranged on one side of the conveyor belt 1, and the air compressor 401 and the solenoid valve 403 are both connected to the electric control mechanism 7 to form a linkage. After the delay is over, the air compressor 401 is turned on to provide a compressed air source for one injection, and the solenoid valve 403 is opened at the same time, connecting the air pipe 402, so that the compressed air source enters the nozzle 404 for one injection. When one injection is over, the computer controls the air compressor 401 and the solenoid valve 403 to close.

[0040] Preferably, one blowing is the amount of gas sprayed by the nozzle 404 for 1s to 2s.

The mounting frame 602 is used to ensure the installation of the knock-down partition 601. On the one hand, it ensures that there is a gap between the knock-down partition 601 and the conveyor belt 1 for the tangerine peel to fall. On the other hand, it ensures the installation stability and ensures that the tangerine peel remains in its original position after being hit, thereby effectively blocking the blown tangerine peel. One end of the mounting frame 602 is welded to the knock-down partition 601, and the other end is provided with a connecting piece. The connecting piece forms a detachable fixed fit with the outer side of the fixing frame of the conveyor belt 1 through a fastener.

[0048] The working principle of this utility model:

[0049] The utility model provides a tangerine peel screening mechanism for preliminary screening. During the tangerine peel conveying process, an image recognition mechanism 2 is installed above a conveyor belt 1. The image recognition mechanism 2 is used to obtain images of the surface of the tangerine peel in real time, and an external computer is used to process the images and recognize in real time whether there are cracks or mildew spots on the surface. When there are cracks or mildew spots, the external computer delays starting a spray mechanism 4 through an electric control mechanism 7. After the delay, the tangerine peel to be sprayed just moves to the air jet port 301. The spray mechanism 4 is started once to spray and clean the tangerine peel in the column to be processed. The column of tangerine peel is blown out from the air outlet 302 by high-speed gas. The blown tangerine peel is recovered by a collection mechanism 6 for manual re-inspection and recycling. The spray mechanism 4 is closed after running once to wait for a delayed start signal. By this method, the tangerine peel with cracks or mildew spots on the surface can be collected and processed in the process of processing a large batch of tangerine peel, so as to ensure the quality of most of the remaining tangerine peel and reduce the workload of subsequent manual quality inspection.
