[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] Example 1

[0021] This embodiment provides a crusher material level calibration device, such as Figures 1-2 As shown, it includes: a clamping member, a first sliding member, a second sliding member and a detection plate 9, the clamping member is used to be detachably fixedly connected to the edge of the observation port 12 of the crusher; the first sliding member is used to be fixedly connected to the clamping member to extend into the inner cavity of the crusher; the second sliding member is slidably connected to the first sliding member in the vertical direction; the detection plate 9 is fixedly connected to the bottom of the second sliding member, and the detection plate 9 is horizontally arranged, and a level meter 10 detection point is provided on the top of the detection plate 9. After the detection plate 9 slides downward to contact with the inner cavity of the crusher, the level meter 10 arranged on the top of the crusher can detect the position of the detection point of the level meter 10 to calibrate the position of the material in the crusher, fix the clamping member to the edge of the observation port 12, adjust the second sliding member to make the detection plate 9 contact with the material in the crusher, and detect the position of the detection point of the level meter 10 through the level meter 10 on the top of the crusher to calibrate the position of the material in the crusher. The structure is simple, easy to use, and effectively improves the accuracy of the material level calibration.

[0022] In a preferred embodiment, the clamping member includes a clamping plate 1, a fastening bolt 2 and a fastening nut 3. A clamping groove is provided on the top of the clamping plate 1, and the clamping groove is used to clamp to the top edge of the observation port 12 of the crusher. A first through hole is provided on the side of the clamping plate 1 away from the first sliding member. The fastening nut 3 is fixedly connected to the outside of the first through hole. The fastening bolt 2 is threadedly connected to the fastening nut 3, and one end of the fastening bolt 2 extends through the first through hole into the clamping groove and presses against the top edge of the observation port 12 of the crusher. The structure is simple and easy to use. The clamping groove is a U-shaped slot with a slot width of 11-12mm and a depth of 90mm. The side plate of the clamping plate 1 is 8-10mm thick and 120mm wide. Two positioning nuts 7 are welded to the side of the clamping plate 1. The nuts are selected as M16, and the distance between the two clamping plate 1 positioning nuts 7 is 40-50mm. The positioning bolt 6 uses an M16*40 bolt.

[0023] In a preferred embodiment, the crusher material level calibration device further comprises a connecting shaft 4, one end of which is fixedly connected to the card plate 1, and the other end is fixedly connected to the first sliding member. The length of the connecting shaft 4 is 40-50 mm, and the connecting shaft 4 can be selected. The connecting shaft 4 is a steel pipe, welded to one side of the clamping plate 1 at a 90° angle. This connection ensures that the clamping plate 1 and the connecting shaft 4 form a single unit, providing a secure and reliable connection. During use, when the clamping plate 1 is secured to the upper edge of the crusher's viewing port 12, the connecting shaft 4 provides stable support for subsequent components, ensuring the stability of the entire assembly. The 90° angle allows the connecting shaft 4 to be perpendicular to the plane of the clamping plate 1, providing the proper orientation for subsequent installation of the positioning sleeve 5 and sliding rod 8.

[0024] In a preferred embodiment, the first sliding member includes a positioning sleeve 5, a positioning bolt 6 and a positioning nut 7, and the second sliding member is a sliding rod 8. The positioning sleeve 5 is fixedly connected to one end of the connecting shaft 4, and the bottom of the sliding rod 8 is vertically fixedly connected to the detection plate 9. The sliding rod 8 is sleeved in the positioning sleeve 5. A second through hole is provided on the side wall of the positioning sleeve 5. The positioning nut 7 is fixedly connected to the outer side of the second through hole. The positioning bolt 6 is used to be threadedly connected to the positioning nut 7, and the positioning bolt 6 can pass through the second through hole and tighten the sliding rod 8. The length of the positioning sleeve 5 is 40-50mm, and the inner diameter of the positioning sleeve 5 is 12mm. A positioning nut 7 is welded on the positioning sleeve 5, and the positioning nut 7 is selected from M6. The positioning bolt 6 is selected from M6*12. The outer diameter of the sliding rod 8 is 10mm. The detection plate 9 is 200-250mm long and 100-200mm wide. The positioning sleeve 5 is welded to the connecting shaft 4 at an angle of 90°. The welded connection ensures the firmness between the positioning sleeve 5 and the connecting shaft 4, and will not loosen or move during use. The 90° angle design makes the positioning sleeve 5 perpendicular to the connecting shaft 4, providing stable support for the installation and adjustment of the sliding rod 8; the sliding rod 8 passes through the positioning sleeve 5 and is fixed with the positioning nut 7 and the positioning bolt 6. This connection method allows the sliding rod 8 to move up and down in the positioning sleeve 5, thereby adjusting the height of the detection point of the level meter 10. The positioning nut 7 and the positioning bolt 6 can firmly fix the sliding rod 8 to prevent it from accidentally moving during use. When the height needs to be adjusted, the position of the sliding rod 8 can be easily adjusted by loosening the positioning bolt 6. The operation is convenient and quick. A detection plate 9 is welded to the bottom of the sliding rod 8. The welded connection ensures the firmness between the detection plate 9 and the sliding rod 8 and will not separate during use. The detection plate 9 can provide a clear detection point for the level meter 10. By adjusting the height of the sliding rod 8, the height of the level meter 10 and the percentage of material in the crushing chamber can be accurately calibrated.

[0025] Example 2

[0026] This embodiment also provides a crusher, such as Figure 3 As shown, the apparatus comprises a crusher body 11, a crusher material level calibration device as in Example 1, and a material level meter 10. The material level meter 10 is disposed at the top of the inner cavity of the crusher body 11. The material level meter 10 is used to detect the position of the detection point of the material level meter 10 to calibrate the position of the material within the crusher. The material level meter 10 primarily determines the material level by detecting the height of the material within the crusher cavity. When the crusher is operating, material accumulates within the cavity. The detection point of the material level meter 10 (located on the detection plate 9) senses changes in the material height through contact with the material or through specific sensing methods (such as ultrasonic waves, radar, etc., and specific types of material level meters 10 may use different detection methods).

[0027] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
