[0038] The working principle of the utility model is as follows: the electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for controlling a computer, etc., and the existing public power connection technology is not repeated in the text. When in use, the calcium carbonate raw material is added to the inside of the material guide cover 13. Under the guidance of the material guide cover 13, the raw material will enter the inside of the crushing box 11. At the same time, the second motor 12 is controlled to start working. The driving end of the second motor 12 drives the crushing shaft 15 to rotate. The rotation of the crushing shaft 15 drives the crushing blade 14 to rotate. The rotation of the crushing blade 14 will crush the raw material to prevent large pieces of raw material from directly entering the device. The grinding is performed inside the device to improve the grinding efficiency and quality. The crushed raw materials will enter the inside of the feed pipe 9 through the guide hole 16, and then enter the inside of the grinding seat 7 through the bottom outlet of the feed pipe 9. At the same time, the first motor 10 is controlled to start working, and the driving end of the first motor 10 drives the grinding block 8 to rotate. The rotation of the grinding block 8 will perform a finer grinding process on the crushed raw materials. Finally, the powdered calcium carbonate will fall to the left side of the top of the sieve plate 6 under the guidance of the guide plate at the bottom of the grinding seat 7, and the ground calcium carbonate will be screened by the sieve plate 6. Because the sieve plate 6 is installed at an angle, the calcium carbonate powder that falls to the top of the sieve plate 6 will Roll to the right. During the rolling process, qualified calcium carbonate will directly pass through the sieve holes on the sieve plate 6 and fall into the bottom of the grinding box 2 and finally be discharged through the discharge pipe at the bottom of the grinding box 2, while unqualified large-particle calcium carbonate will directly fall into the collection box 3 through the discharge hole 25. When the amount of unqualified calcium carbonate collected in the collection box 3 reaches a certain amount, the third motor 18 is controlled to start working, and the driving end of the third motor 18 drives the threaded rod 19 to rotate. Through the threaded transmission of the threaded rod 19 and the adjusting block 5, and the sliding connection between the adjusting block 5 and the vertical slot 17, the adjusting block 5 can stably move vertically. The adjusting block 5 is electrically The movable telescopic rod 4 drives the collection box 3 to move. After the collection box 3 is raised to the specified height, the electric telescopic rod 4 is controlled to start working. The extension of the driving end of the electric telescopic rod 4 drives the collection box 3 to move horizontally, so that the collection box 3 moves directly to the top of the material guide cover 13. Then, the electric valve on the conduit 28 is opened at this time, so that the unqualified calcium carbonate inside the collection box 3 will fall into the inside of the material guide cover 13 again, and undergo the crushing and grinding process again, thereby improving the grinding efficiency and quality. During the use of the device, the device can automatically convey the unqualified calcium carbonate to the device for secondary processing again, without the need for manual material transportation. This automated processing method saves time and effort, reduces the workload, and improves the efficiency of the device. By automatically conveying unqualified calcium carbonate for reprocessing, it is possible to effectively reduce manpower input and improve production efficiency. At the same time, it also reduces the risk of errors in operation, making the device more stable and reliable.

[0039] During the process of conveying unqualified calcium carbonate through the collecting box 3, as the collecting box 3 moves upward, the spring 23, which is in a compressed state at this time, will drive the spring 23 to move upward on the limiting groove 26, and drive the sealing slide 21 to move toward the inside of the discharge hole 25, and the pressing plate 24 moves with the sealing slide 21. Therefore, as the collecting box 3 moves upward, the limiting effect of the sealing slide 21 will be lost, and the sealing slide 21 will enter the inside of the discharge hole 25 under the elastic action of the spring 23 to close the discharge hole 25, so as to prevent the unqualified calcium carbonate from being discharged from the discharge hole 25 during the conveying process of the collecting box 3. When the collecting box 3 completes the conveying and resetting process, the sealing slide 21 will be driven to reset through the pressing plate 24 to continue to collect the unqualified calcium carbonate, thereby realizing continuous conveying and collection without stopping the machine, thereby greatly improving the practicability and efficiency of the device.
