[0063] Step 2: a certain amount of quartz sand raw material is put into the temporary storage cover 401, and the quartz sand slides along the lower hopper 4011 to the conveyor belt body 201, and the raw material is transported to the color sorter body 101 through the conveyor belt body 201, and finally the color sorting operation is completed through the color sorter body 101;

[0064] Step 3: When the quartz sand is transported on the conveyor belt body 201, the driving motor 3012 is started, and the driving motor 3012 drives the driving roller 301 to rotate, and the cylindrical cam groove 302 on the driving roller 301 drives the synchronous component to slide, and the synchronous component drives the push plate 306 and the flattening plate 3061 to slide, and the flattening plate 3061 breaks up the raw materials on the conveyor belt body 201 to ensure that the raw materials are flatly spread on the conveyor belt body 201, and the flattening plates 3061 are tilted and alternately arranged to ensure that the breaking is more thorough, and the situation that some raw materials are stacked together is reduced;

[0065] Step 4: During the rotation of the driving roller 301, the turntable 303 is driven to rotate, and the positions of the protrusions 3032 and the grooves 3031 on the turntable 303 change, thereby driving the entire push rod 304 to slide back and forth left and right, and the push rod 304 drives the synchronous rod 305 to slide synchronously, and the synchronous rod 305 drives the flattening plate 3061 to move left and right continuously, thereby increasing the range of the flattening plate 3061 that can contact the raw materials, so that the raw materials can be better flattened on the conveyor belt body 201, which is convenient for later inspection, and the raw materials can be broken up during the flattening process, reducing the impact of agglomeration on sorting, and the synchronous rod 305 pushes the raw materials with higher thickness during the sliding process to ensure that the raw materials sent for inspection are at the same height, which is convenient for the sorting unit 100 to perform sorting operations;

[0066] Step 5: During the rotation of the driving roller 301, the driving roller 301 drives the guide plate 405 to rotate, and the position of the eccentric block 4051 on the side wall of the guide plate 405 is constantly changing, thereby driving the special-shaped plate 4041 to continuously swing, and finally driving the sliding rod 403 on the special-shaped plate 4041 to slide vertically, the sliding rod 403 drives the plug rod 402 to slide, and the plug rod 402 drives the blocking block 4022 to slide, and after the blocking block 4022 is inserted into the discharge port 4023, the discharge unit 400 stops discharging, ensuring that the raw materials on the conveyor belt body 201 are not stacked too much, ensuring that the flattening unit 300 can smoothly perform the flattening operation, and facilitating the later sorting.

[0067] The implementation principle of the quartz sand purification color sorting device and its process of this embodiment is as follows:

[0068] A certain amount of quartz sand raw material is put into the temporary storage cover 401, and the quartz sand slides along the lower hopper 4011 to the conveyor belt body 201, and the raw material is transported to the color sorter body 101 through the conveyor belt body 201, and finally the color sorting operation is completed through the color sorter body 101.

[0069] When quartz sand is being transported on the conveyor belt body 201, the operator can start the driving motor 3012 installed on the mounting seat 3011, and the driving motor 3012 drives the driving roller 301 to rotate, and the cylindrical cam groove 302 on the driving roller 301 drives the synchronous component to slide, wherein the limit slider 3021 inside the synchronous component slides along the cylindrical cam groove 302, and the limit block 3023 at the bottom of the limit slider 3021 is limited by the limit rod 3024, and then when the cylindrical cam groove 302 rotates at this time, the limit slider 3021 can slide back and forth along the axial direction of the driving roller 301, and the limit block 3023 slides along the limit rod 3024 during the sliding process, and can also compress the limit spring 3025, and the limit spring 3025 is used to facilitate the later reset operation.

[0070] Finally, the limit block 3023, driven by the guide rod 3052, can drive the sliding sleeve 3051 to slide along the synchronous rod 305, and the sliding sleeve 3051 will drive the push plate 306 and the flattening plate 3061 to slide. At this time, the flattening plate 3061 breaks up the raw materials on the conveyor belt body 201 to ensure that the raw materials are flatly spread on the conveyor belt body 201, and the flattening plates 3061 are tilted and alternately arranged to ensure that the breaking is more thorough, thereby reducing the occurrence of some raw materials stacking together.

[0071] During the rotation of the driving roller 301, the rotating disk 303 is driven to rotate, and the positions of the protrusions 3032 and the grooves 3031 on the rotating disk 303 change. At this time, the guide wheel 3042 always slides on the surfaces of the protrusions 3032 and the grooves 3031, thereby driving the connecting seat 3041 and the push rod 304 to slide back and forth left and right, and the synchronous rod 305 connected to the push rod 304 slides synchronously, and the synchronous rod 305 drives the flattening plate 3061 to move left and right continuously, thereby increasing the range of the flattening plate 3061 that can contact the raw materials, so that the raw materials can be better flattened on the conveyor belt body 201, which is convenient for later inspection, and the raw materials can be broken up during the flattening process, reducing the influence of agglomeration on sorting, and the synchronous rod 305 pushes the raw materials with higher thickness during the sliding process to ensure that the raw materials sent for inspection are at the same height, which is convenient for the sorting unit 100 to perform sorting operations;

[0072] When the push rod 304 moves, the reset rod 3043 on the push rod 304 can slide inside the reset cover 3044, and the reset plate 3046 at the end of the reset rod 3043 slides inside the reset cover 3044, and squeezes the reset spring 3047 between the reset plate 3046 and the positioning seat 3045, so that the reset operation can be facilitated later through the reset spring 3047.

[0073] During the rotation of the driving roller 301, the driving roller 301 drives the guide plate 405 to rotate, and the position of the eccentric block 4051 on the side wall of the guide plate 405 keeps changing. At this time, the eccentric block 4051 slides on the strip groove 4042 of the special-shaped plate 4041, and finally drives the special-shaped plate 4041 to swing around the holder 404, and finally drives the strip groove 4042 on the other side of the special-shaped plate 4041 to drive the slide bar 403 to slide up and down. The positioning block 4031 on the slide bar 403 slides along the positioning rod 4032 at this time, and then squeezes the positioning spring 4034 at the bottom, so as to facilitate the subsequent resetting operation, and a positioning plate 4033 is installed on the positioning rod 4032, so as to ensure that the positioning block 4031 and the positioning rod 4032 will not separate. When the slide rod 403 drives the insertion rod 402 to slide, the insertion rod 402 drives the blocking block 4022 to slide through the synchronous plate 4021. After the blocking block 4022 is inserted into the discharge port 4023, the discharge unit 400 stops discharging, ensuring that the raw materials on the conveyor belt body 201 will not be stacked too much, ensuring that the flattening unit 300 can smoothly perform the flattening operation, which is convenient for later sorting.
