A flexible conduit is connected between the three-way electromagnetic valve 342 and the piston plate 32 for extracting air from the plurality of insertion holes. A gas guide pipe is connected between the plurality of multi-directional output pipes 34.

[0037] The air extraction ring 341 includes an electrically controlled three-way valve communicated with the gas guide pipe, a gas guide ring connected to the side output end of the electrically controlled three-way valve, and a plurality of air holes opened in the gas guide ring and facing the air cavity.

[0038] A plurality of uniformly distributed crushing discs 4 are sleeved on the crushing shaft 3. Positioning holes matched with the positioning pins 33 are opened in the inner side of the crushing disc 4. A sealing ring is fixedly connected to the opening at both ends of the inner side of the crushing disc 4. A pressure sensor is installed at the top end of the positioning pin 33.

[0039] The support 1 is provided with a driving motor 6 for driving the crushing shaft 3 to rotate and an air extraction pump 7 for extracting and supplying air to the plurality of multi-directional output pipes 34.

[0040] The middle part of the top end of the auxiliary plate 22 is provided with a receiving groove, and a detection unit 231 is fixedly connected in the receiving groove.

[0041] A permanent magnet ring for resetting the positioning pin 33 is mounted in the insertion hole, and when the positioning pin 33 is in the initial position, the positioning pin 33 is completely received in the slot hole and the air cavity, and when the positioning pin 33 is completely elongated, the positioning pin 33 is inserted into the positioning hole on the inner side of the crushing disc 4.

[0042] The movable baffle is connected between the outer wall of the feeding hopper and the movable baffle, and the moving distance of the movable baffle matches the displacement distance of the crushing disc 4 during adjustment.

[0043] The adjacent two slide rails on the auxiliary plate 22 are respectively mounted on the upper end and the lower end thereof;

[0044] When the distance between the crushing discs 4 on the crushing shaft 3 is adjusted, the air pump 7 is used to draw and supply air to each multi-directional output pipe 34, so that the air pressure of the air cavities on both sides of the piston plate 32 changes, and then the position of the piston plate 32 is adjusted. By adjusting the position of the piston plate 32, the positioning pin 33 drives the crushing disc 4 to move along the length direction of the slot hole, so that the position of the crushing disc 4 is adjusted.

[0045] The same air drawing and discharging operation is performed on the plurality of air cavities to comprehensively adjust the positions of the plurality of crushing discs 4, so that the distance between them is uniformly reduced or increased.

[0046] During the position adjustment of the plurality of crushing discs 4, the laser sensors of the detection unit 231 on the movable rib plate 23 are used to detect the distance between the adjacent crushing discs 4. After the distance is detected, if the distance is qualified, the position of the movable rib plate 23 is adjusted by the small air cylinder, so that the movable rib plate 23 is displaced to the middle position between the adjacent movable rib plates 23, that is, the detection unit 231 detects that the distance between the adjacent two crushing discs 4 is the same.

[0047] The embodiment realizes the automatic adjustment and detection of the distance between the crushing discs in the ore particle controllable crusher, and improves the precision and efficiency of ore crushing. By drawing and supplying air to the multi-directional output pipe by the air pump, the sliding of the piston plate in the air cavity is realized, and then the position adjustment of the crushing disc on the crushing shaft is realized. This adjustment method is flexible and accurate, and can quickly change the crushing particle size of the ore according to the actual needs.

[0048] Meanwhile, the detection units and their laser sensors on the movable ribbed plate play a key role in detection. They can monitor the spacing between adjacent crushing discs in real time, ensuring the uniformity of the spacing, thereby ensuring the uniformity of the crushed ore particle size. When the spacing is qualified, the small air cylinder will automatically adjust the position of the movable ribbed plate, so that it is stably supported between adjacent crushing discs, further enhancing the stability and reliability of the equipment.

[0049] In summary, the present embodiment facilitates the adjustment of the spacing of the crushing discs 4, the adjustment of the ore particle size, and the rapid detection of the spacing of the crushing discs 4 after adjustment. It can timely detect the crushing discs 4 with abnormal positions after adjustment, and easily realize the accurate control of the particle size of the output ore particles.

[0050] The second embodiment:

[0051] It also includes an auxiliary crushing system, which includes a processor connected with a control module, a data processing module, a data acquisition module and a warning module;

[0052] The control module is used to control the operation of related equipment;

[0054] The data processing module is used to process the monitoring data and determine whether an abnormality occurs during the adjustment of the crushing discs 4;

[0055] The warning module alarms when an abnormality occurs during the adjustment of the crushing discs 4.

[0056] When the warning module detects a crushing disc 4 with unqualified monitoring data after adjustment, it stops and alarms, and at the same time controls the movement of the auxiliary plate 22 at the corresponding position to be in contact with it, which is used to mark the abnormal crushing disc 4, so that the staff can timely find it during maintenance; the unqualified monitoring data may be, for example, the detected spacing of the crushing discs 4 or the pressure value at the positioning pin 33 is not within the set value range,

[0057] The present embodiment realizes the intelligent management of the ore particle size controllable crusher. By introducing the auxiliary crushing system, the equipment not only can automatically adjust the spacing of the crushing discs 4, but also can monitor and adjust various key parameters in real time, ensuring the accuracy and efficiency of ore crushing.

[0058] When the warning module detects an abnormal crushing disc 4, it will automatically control the movement of the auxiliary plate at the corresponding position to be in contact with it, thereby marking the abnormal position; this facilitates the subsequent maintenance work of the staff, enabling them to quickly locate and solve the problem, and ensuring the continuous and stable operation of the equipment.

[0059] In conclusion, the ore particle size controllable type crusher of the embodiment can realize intelligent management and overall monitoring of the crushing process by introducing an auxiliary crushing system.

[0060] In combination with the current actual demand, the above-mentioned embodiments adopted by the application are not limited to this, various changes made within the knowledge range of the skilled in the art without departing from the concept of the application still fall within the protection scope of the application.
