Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] like Figures 1 to 4 As shown, this embodiment includes a housing 1, which is U-shaped. A fixing block 2 is installed inside the housing 1. A grinding chamber 3 is arranged on the upper end of the fixing block 2. A lifting plate 4 is installed above the grinding chamber 3. A motor 5 is installed on the upper end of the lifting plate 4. A connecting shaft 6 is installed on the output end of the motor 5. A grinding block 7 is installed on the lower end of the connecting shaft 6. The grinding block 7 is moved up and down by the lifting plate 4, which facilitates the removal of the grinding block 7 from the inside of the grinding chamber 3 and makes it convenient to clean the grinding block 7 and the inside of the grinding chamber 3. Discharge grooves 8 are arranged on both sides of the bottom end of the grinding chamber 3. The discharge grooves 8 are used to discharge the ground raw materials. A rotating shaft 9 is installed inside the housing 1 between the two discharge grooves 8. A connecting plate 10 is installed on the front and rear parts of the rotating shaft 9. The connecting plate 10 is shaped like an equal part. The structure is a trapezoidal shape, with guide plates 11 installed between the isosceles sides of the two connecting plates 10. By rotating the connecting plates 10, the guide plates 11 are rotated, so that the two guide plates 11 are in a V-shape or an inverted V-shape. The guide plates 11 can allow the raw materials discharged from the discharge trough 8 to fall from the middle for re-grinding or be discharged directly from both sides, which is convenient to choose re-grinding or direct discharge according to the actual grinding effect. A collection hopper 12 is installed inside the shell 1 below the two guide plates 11. The collection hopper 12 is used to collect the raw materials that need to be re-grinded. A feeding component is installed at the rear end of the shell 1. The feeding component is used to feed the raw materials that need to be re-grinded. A discharge plate 14 is installed at both ends of the shell 1. The discharge plate 14 is used to discharge the ground raw materials.

[0021] Specifically, the opposing surfaces of the housing 1 on both sides of the grinding chamber 3 are provided with moving grooves 15. Motors 2 16 are installed at the upper ends of both sides of the housing 1. The output end of motor 2 16 is located inside the moving groove 15 and is equipped with a drive screw 17. The drive screw 17 is threadedly connected to a connecting plate 2 18. The lifting plate 4 is installed between the two connecting plates 2 18. The drive screw 17 is driven to rotate by motor 2 16. The drive screw 17 drives the lifting plate 4 to rise and fall through the connecting plate 2 18, thereby adjusting the height of the grinding block 7. Motor 2 16 is connected to a forward and reverse circuit, which can realize the forward and reverse rotation of motor 2 16.

[0022] Furthermore, a connecting rod 19 is installed at the lower end of the lifting plate 4, and a cover plate 20 is installed at the lower end of the two connecting rods 19. When the grinding block 7 is inside the grinding chamber 3, the cover plate 20 can cover the grinding chamber 3 to prevent splashing during the grinding process. A feeding hopper 21 is installed at the upper end of the lifting plate 4 on both sides of the motor 5, and a feeding pipe 22 is installed at the lower end of the feeding hopper 21. The end of the feeding pipe 22 extends between the grinding chamber 3 and the grinding block 7. The feeding hopper 21 is used to add the raw materials that need to be ground.

[0023] Furthermore, the two guide plates 11 are arranged in a V-shape, and an adjustment block 23 is installed at the front end of the rotating shaft 9. The surface of the adjustment block 23 is fitted with a fixing bolt 24 through a screw hole. By observing the shape of the adjustment block 23, it can be determined whether the two guide plates 11 are in a V-shape or an inverted V-shape, which makes it easy to understand the state of the guide plates 11. The fixing bolt 24 is used to fix the adjustment block 23, thereby fixing the rotating shaft 9 after rotation.

[0024] Furthermore, the feeding assembly includes a return pipe 1301, a feeding pipe 1302, a auger blade 1303, a discharge pipe 1304, and a motor 1305. The feeding pipe 1302 is installed at the rear end of the housing 1. The lower end of the feeding pipe 1302 is connected to the collection hopper 12 through the return pipe 1301. The motor 1305 is installed at the upper end of the feeding pipe 1302. The output end of the motor 1305 is located inside the feeding pipe 1302 and is equipped with the auger blade 1303. The upper outlet of the feeding pipe 1302 is connected to the grinding chamber 3 through the discharge pipe 1304. The raw material inside the collection hopper 12 enters the feeding pipe 1302 through the return pipe 1301. The motor 1305 drives the auger blade 1303 to transport the raw material inside the feeding pipe 1302 and discharge it through the discharge pipe 1304, which can realize the re-feeding of raw materials.

[0025] Furthermore, the feeding plate 14 is arranged at an angle, and a collection box 25 is placed below each feeding plate 14. The collection box 25 is used to collect the ground raw materials for subsequent processing.

[0026] The usage method of this embodiment is as follows: The drive screw 17 is driven to rotate by the motor 5. The drive screw 17 drives the lifting plate 4 to move down through the connecting plate 18, so that the grinding block 7 is located inside the grinding chamber 3. Then, the motor 5 drives the grinding block 7 to rotate inside the grinding chamber 3. Then, the raw material is added into the feed hopper 21 and discharged into the grinding chamber 3 through the feed pipe 22. The grinding block 7 grinds the raw material. The ground raw material is discharged through the discharge trough 8. The method can be adjusted according to actual needs to directly discharge or grind again. When the two guide plates 11 are V-shaped, the raw material discharged from the discharge trough 8 passes through the two guide plates 11 and falls into the collection hopper 12 through the gap between the two guide plates 11. The raw material in the collection hopper 12 enters the feed pipe 1302 through the return pipe 1301. Motor 3 1305 drives the auger blades 1303 to transport the raw materials inside the feeding pipe 1302 and discharge them through the discharge pipe 1304, which can realize the re-feeding of raw materials and re-grinding of raw materials. When it is necessary to discharge raw materials, the rotating adjustment block 23 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the connecting plate 10 and the guide plate 11 to rotate, so that the two guide plates 11 are inverted V shape. Since the two discharge slots 8 are located above the guide plates 11, the raw materials discharged from the discharge slots 8 are discharged to both sides through the surface of the guide plates 11 and discharged into the collection box 25 through the feeding plate 14, completing the grinding of raw materials. After grinding, the motor 5 drives the grinding block 7 to rise, so that the grinding block 7 is removed from the grinding chamber 3, and the grinding block 7 and the inside of the grinding chamber 3 can be cleaned.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
