[0024] The additional aspects and advantages of the utility model will be further given in the following description combined with the drawings, some will become obvious from the following description, or be understood through the practice of the utility model.

[0025] As Figures 1 to 6 shown, an ore granularity image acquisition device, it includes the conveying belt unit 1 for conveying ore, the conveying belt unit 1 is fixedly installed with support 2, support 2 is installed with image acquisition assembly 3 in the inside; image acquisition assembly 3 includes mounting box 31 fixedly installed in the inside of support 2, image acquisition unit 32 is fixedly installed in the inside of mounting box 31, rotatingly arranged film 4 in the inside of mounting box 31, drive assembly 5 for controlling the rotation of film 4 is arranged on mounting box 31, cleaning assembly 6 for cleaning the dust adhered to the surface of film 4 is arranged on mounting box 31; cleaning assembly 6 includes frame 61 fixedly installed on mounting box 31, a plurality of water seepage pipes 62 are rotatably arranged in the inside of frame 61, the bottom end of a plurality of water seepage pipes 62 is closed, the outer surface of a plurality of water seepage pipes 62 is all sleeved with sponge column 63 for sticking the dust adhered to the surface of film 4, sponge block 64 for wiping the outer surface of film 4 is placed in the inside of frame 61, water supply assembly 7 for providing water source in the inside of water seepage pipe 62 is fixedly installed on the top of frame 61, sawtooth comb 65 is fixedly installed on the side of frame 61 away from film 4, cover plate 8 is fixedly installed on the side of frame 61 away from mounting box 31.

[0026] As a preferred technical solution of this utility model, the drive assembly 5 includes an electric drive roller shaft 51 and a driven roller shaft 52. Both the electric drive roller shaft 51 and the driven roller shaft 52 are rotatably disposed inside the mounting box 31. The electric drive roller shaft 51 is used to control the rotation of the film 4. The electric drive roller shaft 51 and the image acquisition unit 32 described in this application are known technologies in this technical field, so their specific structures and working principles are not described in detail.

[0027] As a preferred technical solution of this utility model, the outer surface of the seepage pipe 62 is provided with a plurality of seepage holes 621, and the frame 61 is provided with a drain outlet 611 at the bottom end of the seepage pipe 62. By using the plurality of seepage holes 621, water is distributed inside the sponge column 63 through the seepage holes 621 of the seepage pipe 62. By using the drain outlet 611, the serrated comb 65 scrapes off the dust particles adhering to the surface of the sponge column 63, and then the detached dust particles fall out from the drain outlet 611, so as to avoid them adhering to the surface of the sponge column 63 and the surface of the film 4 again.

[0028] As a preferred technical solution of this utility model, the water supply component 7 includes a water tank 71 fixedly installed on the top of the frame 61. The water tank 71 is provided with a water injection pipe 72. The top ends of multiple seepage pipes 62 all penetrate the frame 61 and are inserted into the interior of the water tank 71. As water inside the water tank 71 gradually enters the interior of the seepage pipes 62, the water is then distributed inside the sponge column 63 through the seepage holes 621 of the seepage pipes 62. When the membrane 4 rotates, the friction force can be used to make the membrane 4 drive the sponge column 63 and the seepage pipes 62 to rotate, thereby squeezing the water on the surface of the sponge column 63 to seep out, thus wetting the surface of the membrane 4 and avoiding dry friction.

[0029] As a preferred technical solution of this utility model, the frame 61 is provided with rotating holes at the positions of the multiple seepage pipes 62. The multiple seepage pipes 62 are connected to the rotating holes through bearings. By using the bearings, the friction force when the seepage pipes 62 rotate can be reduced and the stability of the seepage pipes 62 when rotating can be improved.

[0030] The work process is as follows:

[0031] S1, such as Figures 1 to 3 As shown, during use, the image acquisition unit 32 is shielded and protected by the thin film 4 to prevent dust from falling on the lens of the image acquisition unit 32;

[0032] S2, such as Figures 3 to 6 As shown, when dust adheres to the surface of the film 4, the film 4 is rotated by the cooperation between the electric drive roller 51 and the driven roller 52, so that the area of ​​the film 4 with dust adheres can enter the cleaning component 6.

[0033] S3, such as Figures 3 to 6As shown, when the area of the film 4 attached with dust enters the inside of the cleaning assembly 6, the sponge column 63 will be in contact with the film 4 in advance, and then the wet sponge column 63 can stick the dust particles attached on the surface of the film 4 (as the water in the water tank 71 can gradually enter the inside of the water seepage pipe 62, and then the water is distributed in the inside of the sponge column 63 through the water seepage hole 621 of the water seepage pipe 62, when the film 4 rotates, the film 4 can drive the sponge column 63 and the water seepage pipe 62 to rotate by using the friction force, so that the water on the surface of the sponge column 63 can seep out by using the extrusion force, so that the surface of the film 4 can be wetted, and the dry grinding phenomenon can be avoided) ;

[0034] S4、as shown in Figures 3 to 5 As shown, when the sponge column 63 sticks the dust particles attached on the surface of the film 4, the sawtooth comb 65 can scrape the dust particles attached on the surface of the sponge column 63, and then the detached dust particles can fall out of the sewage outlet 611, so as to avoid being attached on the surface of the sponge column 63 and the surface of the film 4 again.

[0035] S5、as shown in Figure 3 and Figure 4 As shown, when the film 4 passes through the sponge column 63, the film 4 will be in contact with the sponge block 64, and then the sponge block 64 can wipe the surface of the film 4, so that the surface of the film 4 becomes transparent, and the area of the film 4 in front of the lens of the image acquisition unit 32 can always keep transparent.

[0036] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the present application.
