Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 2 The utility model provides an embodiment of a raw material ball mill for producing resistor slurry, comprising a base 1, which is the basic supporting structure of the equipment and provides stable support for the entire equipment. A protective block 2 is fixedly connected to the top of the base 1, and a driving assembly for rotation is installed inside the protective block 2. The driving assembly includes a motor 3, which is responsible for providing power to enable the equipment to operate normally. The outside of the motor 3 is fixedly connected to the inside of the protective block 2, and the driving end of the motor 3 is fixedly connected to a gear 4. By starting the motor 3, the gear 4 can be rotated in the desired direction. The top of the protective block 2 is fixedly connected to a protective cylinder 5.

[0034] The protective block 2 can not only protect the internal motor 3, but also support the protective cylinder 5. The internal rotation of the protective cylinder 5 is connected to the ball mill body 6, and the outside of the ball mill body 6 is fixedly connected to the gear 2 7. The gear 2 7 and the gear 1 4 are meshingly connected. When the gear 1 4 rotates counterclockwise, it will drive the gear 2 7 to rotate clockwise, so that the ball mill body 6 can rotate under the support and protection of the protective cylinder 5. The rear side of the ball mill body 6 is fixedly connected to the feed port 8 for conveying raw materials into the interior of the ball mill body 6. The front side of the ball mill body 6 is fixedly connected to the discharge port 9 for discharging the ground raw materials.

[0035] Reference Figure 1 and Figure 3, the top of the base 1 is fixedly connected to two supporting rods 10 for providing support, the top of the base 1 is fixedly connected to a limiting rod 11, the outer rotation of the limiting rod 11 is connected to a screen 12 for screening the raw materials, the outer rotation of the limiting rod 11 is connected to a sieve plate 13, the screen 12 and the sieve plate 13 can be rotated by the limiting rod 11, the front side of the sieve plate 13 is fixedly connected to a discharge box, the sieve plate 13 is used to hold the screened raw materials, so that the screened raw materials can be transported to the required place through the discharge box, the front and rear sides of the sieve plate 13 are fixedly connected to two connecting blocks 14 for fixing the screen 12 and the sieve plate 13 together, the outer side of the screen 12 is fixedly connected to the adjacent side of the two connecting blocks 14, and the adjacent side of the two connecting blocks 14 is installed with a vibration component for shaking;

[0036] The vibration assembly includes a support plate 15, the front and rear sides of the support plate 15 are respectively fixedly connected to the adjacent sides of the two connecting blocks 14, and the top of the support plate 15 is fixedly connected to a vibration motor 16 for providing power for vibration. The vibration motor 16 can be installed through the support plate 15, and the outside of the connecting block 14 is fixedly connected to a sliding block 17, and the outside of the sliding block 17 is fixedly connected to two spring columns 18. The outside of the sliding block 17 is slidably connected to the inside of the support rod 10, and the outside of the spring column 18 is fixedly connected to the inside of the support rod 10. When the vibration motor 16 is started, the connecting block 14 will transmit the force to the sliding block 17, causing the sliding block 17 to vibrate up and down inside the support rod 10, thereby squeezing the spring column 18, causing the spring column 18 to undergo elastic deformation, thereby effectively performing buffering and vibrating at the same time.

[0037] Reference Figure 1 and Figure 4 , a plurality of brackets 19 are fixedly connected to the top of the base 1, and a conveyor belt 20 is fixedly connected inside the plurality of brackets 19. The conveyor belt 20 can be installed through the bracket 19. The conveyor belt 20 is rotatably connected to two scrapers 21 inside, and the outside of the scraper 21 is fixedly connected to a spring column 22. The outsides of the two spring columns 22 are respectively fixedly connected to the adjacent sides of two of the brackets 19. By starting the conveyor belt 20, the raw materials will be restricted by the scraper 21, so that the raw materials will be kept in the center of the conveyor belt 20, so that they will not scatter during the transmission process and fall out of the conveyor belt 20. When encountering large pieces of raw materials, the two scrapers 21 will be squeezed, causing the scraper 21 to squeeze the spring column 22, causing the spring column 22 to undergo elastic deformation, and the opening formed by the two scrapers 21 will become larger, allowing the raw materials to pass through.

[0038] Reference Figure 1 、 Figure 5 and Figure 6, wherein the adjacent side of the two brackets 19 is fixedly connected with a stabilizing bar 23, and the top of the stabilizing bar 23 is fixedly connected with two spring columns 3 24, which can be installed through the stabilizing bar 23, and the top of the two spring columns 3 24 is slidably connected with a scraper 25, and the left and right sides of the scraper 25 are respectively rotatably connected to the adjacent side of the two brackets 19. When there is a lump of raw material on the conveyor belt 20, the cooperation between the spring column 3 24 and the stabilizing bar 23 can make the scraper 25 get an elastic support, so that when scraping off the agglomeration, the scraper 25 will not be damaged due to the agglomeration being too hard, so that the scraper 2 25 can be used for a long time. A water tank 26 is fixedly connected to the top of the base 1 for storing water. A water pump 27 is fixedly connected to the top of the water tank 26. The output end of the water pump 27 is fixedly connected to a water pipe 28. The rear side of the water pipe 28 is fixedly connected to a spray head 29. Two positioning long blocks 30 are fixedly connected to the top of the water tank 26. The left and right sides of the spray head 29 are respectively fixedly connected to the adjacent sides of the two positioning long blocks 30. Through the water pump 27, water can be transported to the water pipe 28, so that the spray head 29 can spray water to the bottom of the conveyor belt 20, thereby softening the raw material lumps and making it easy for the scraper 25 to scrape them off.

[0039] Working principle: First, when the equipment is in use, the motor 1 (3) inside the protective block (2) is started, which enables the gear 1 (4) to rotate counterclockwise, and then drives the gear 2 (7) to rotate clockwise under the protection limit of the protective cylinder (5), so that the raw materials can enter the ball mill body (6) through the feed port (8) for grinding. When the grinding is completed, the motor 1 (3) rotates clockwise, so that the gear 2 (7) drives the ball mill body (6) to move counterclockwise. At this time, the ground raw materials will be discharged through the discharge port (9) to the inside of the screen (12);

[0040] At this time, the vibration motor 16 is started, and under the restriction of the limiting rod 11, the screen 12 and the sieve plate 13 can vibrate. However, during the vibration, the screen 12 will drive the connecting block 14 so that the sliding block 17 can squeeze the spring column 18, which will cause the spring column 18 to elastically deform. The elastic deformation of the spring column 18 can effectively buffer the screen 12 and the sieve plate 13, so that they can be buffered during the vibration process, thereby avoiding damage to the screen 12 and the sieve plate 13.

[0041] Secondly, when loading is required, the raw materials are conveyed to the conveyor belt 20, which is then started to convey the raw materials to the feed port 8. During the conveying process, the raw materials are restricted by the scraper 1 21, which can keep the raw materials in the center of the conveyor belt 20. When encountering large pieces of raw materials, the scraper 1 21 is squeezed, causing the scraper 1 21 to transmit the received force to the spring column 22, causing the spring column 22 to undergo elastic deformation, thereby effectively protecting the scraper 1 21 and extending the service life of the scraper 1 21.

[0042] Subsequently, when the raw materials are lumped on the scraper 1 21, water can be transported to the water pipe 28 through the water pump 27 and then sprayed to the bottom of the conveyor belt 20 through the positioning long block 30, so that the lumped raw materials can become soft. The stabilizing bar 23 supports the spring column 3 24, so that the spring column 3 24 can lift the scraper 2 25, so that the scraper 2 25 fits the bottom of the conveyor belt 20, and then when the conveyor belt 20 is running, the scraper 2 25 can remove the lumped raw materials.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
