Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a mineral product grinding device, including a base 1, a grinding tank 2 fixedly connected to the middle of the top wall of the base 1, a feed inlet 3 opened on the top wall of the grinding tank 2, a grinding assembly for grinding mineral products installed on the top of the base 1, the grinding assembly including a support plate 4 fixedly connected to the left end of the top wall of the base 1, a fixed plate 41 fixedly connected to the top wall of the support plate 4, and a discharge assembly for controlling the output size of the ground mineral products installed inside the grinding tank 2; the assembly also includes a motor 42, the motor 42 being connected to support rods 4 on both sides. 3. The motor 42 is fixedly installed on the top wall of the fixed plate 41. The output end of the motor 42 is fixedly connected to the first connecting rod 44. The bottom of the first connecting rod 44 is fixedly connected to the fixing block 45. The end of the fixing block 45 is inclined. The bottom of the fixing block 45 is installed with the positioning post 47. The top of the positioning post 47 is fixedly connected to the second connecting rod 46. The top of the second connecting rod 46 is fixedly connected to the fixing block 45. The bottom of the positioning post 47 is fixedly connected to the grinding ball 48. The bottom of the outer surface of the grinding ball 48 has multiple fixed protrusions 49 arranged in a ring array with the center of the grinding ball 48 as the axis.

[0021] Through the above technical solution, the base 1 is composed of a grinding component and a discharge component, while the support plate 4 and the fixed plate 41 provide a support platform for the grinding component. The bottom of the fixed block 45 needs to have a certain slope, so that the positioning column 47 and the grinding ball 48 can be rotated by the second connecting rod 46, thereby achieving the grinding effect on the mineral product. The grinding effect on the mineral product can be further improved by fixing multiple fixed protrusions 49 on the outer surface of the grinding ball 48.

[0022] Please see Figure 2 , Figure 4 and Figure 5 The grinding jar 2 has an inner cavity 6, which is connected to the feed inlet 3. The bottom of the grinding jar 2 has a discharge cavity 7, and the front end of the outer wall of the grinding jar 2 has a discharge outlet 8. The surface of the discharge cavity 7 is designed with a slope and is connected to the discharge outlet 8. The discharge assembly includes a grinding cover 5, which is installed inside the inner cavity 6. A fixing ring 51 is fixedly connected to the top wall of the grinding cover 5. The grinding cover 5 is hemispherical, and its outer surface has multiple discharge holes 52 arranged in a ring array with the central axis as the reference. The outer wall of the fixing ring 51 and the inner wall of the grinding jar 2 are both provided with mounting holes 53 at equal intervals. The fixing protrusion 49 on the outer wall of the grinding ball 48 is in contact with the inner wall of the grinding cover 5.

[0023] Through the above technical solution, the feed inlet 3, inner cavity 6, discharge cavity 7 and discharge port 8 are designed to be connected from top to bottom, ensuring the integrated design of mineral products from feeding to discharging. At the same time, the surface of the discharge cavity 7 is designed to be inclined, and its end is connected to the discharge port 8 to realize the automatic collection of mineral powder. The grinding cover 5 is fixedly connected to the fixing ring 51 and connected to the inner wall of the grinding tank 2 through the mounting hole 53. The grinding cover 5 can be quickly disassembled and assembled through bolts or other structural designs, so that the grinding cover 5 with the appropriate size discharge hole 52 can be replaced according to different usage conditions.

[0024] Please see Figure 2 and Figure 5 The top of the feed inlet 3 is designed to be inclined; a control switch 9 is installed on the front end of the top wall of the base 1, and the control switch 9 is electrically connected to the motor 42.

[0025] Through the above technical solution, the inclined design of the inlet 3 facilitates the centralized feeding of metal mineral products, reduces manual intervention, and improves feeding efficiency; the base 1 controls the start and stop of the motor 42 through the control switch 9, thereby improving the convenience of use and the safety of operation of the device.

[0026] Working principle: First, the motor 42 is started. The motor 42 is fixedly connected to the top wall of the fixed plate 41 via the support rods 43 on both sides. The support plate 4 provides a support platform for the motor 42 and the fixed plate 41. After the motor 42 starts, it drives the first connecting rod 44. The first connecting rod 44 rotates with the motor 42, thereby driving the bottom fixed block 45 to rotate. The end of the fixed block 45 is designed to be inclined. Through the second connecting rod 46, it drives the bottom positioning column 47 and grinding ball 48 to rotate synchronously, so that the positioning column 47 and grinding ball 48 make a circular rotation around the first connecting rod 44. Then, the metal ore product to be ground is poured into the feed inlet 3. Since the opening of the feed inlet 3 is designed to be inclined, it can ensure that the ore product enters the inner cavity 6 stably. The inner cavity 6 and the feed inlet 3 are connected. The design ensures sufficient space for the positioning column 47 to rotate. The mineral product is crushed and ground through frictional contact between the fixed protrusion 49 on the outer surface of the grinding ball 48 and the inner wall of the grinding cover 5. The outer surface of the grinding cover 5 is provided with a feeding hole 52 for the mineral powder to pass through. The ground mineral product enters the inclined feeding chamber 7 through the feeding hole 52. The operator collects the ground material from the discharge port 8 to ensure the grinding and collection effect of the device. When it is necessary to adjust the grinding size of the mineral, the fixing ring 51 on the top wall of the grinding cover 5 is removed from the inner wall of the grinding tank 2 through the mounting hole 53, and a grinding cover 5 with a suitable feeding hole 52 is installed. The detachable combined discharge assembly can be adjusted according to different grinding needs, thereby improving the practicality and applicability of the device.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
