The T-shaped positioning strips 503 are movably installed in the corresponding T-shaped positioning grooves 502. When the L-shaped lifting plate 5 is taken out from the first cylinder body 2 or the second cylinder body 3, the L-shaped lifting plate 5 will drive the T-shaped positioning strip 503 to disengage from the T-shaped positioning groove 502.

[0068] Among them, the jacking assembly includes two electric push rods 504 respectively arranged on the base 1 and the movable seat 4.

The output end of the electric push rod 504 can extend into the positioning hole 614 and contact the L-shaped lifting plate 5, and finally jack out the L-shaped lifting plate 5 from the first cylinder body 2 or the second cylinder body 3. When the positions of the positioning hole 614 and the output end of the electric push rod 504 are staggered, the output end of the electric push rod 504 can abut against the first cylinder body 2 or the second cylinder body 3 to limit its position.

[0069] Embodiment 2:

[0070] On the basis of Embodiment 1, in order to achieve rapid maintenance of the first cylinder body 2 and the second cylinder body 3 and improve the connection stability between the first cylinder body 2 and the second cylinder body 3, a locking structure for connecting and separating the first cylinder body 2 and the second cylinder body 3 is arranged on the first cylinder body 2 and the second cylinder body 3, and an adjusting structure for controlling the separation of the first cylinder body 2 and the second cylinder body 3 is arranged on one side of the movable seat 4.

[0071] Among them, the locking structure includes a first connecting ring 6 arranged on the first cylinder body 2, an internally threaded collar 601 rotatably mounted on the first connecting ring 6, a second connecting ring 602 arranged on the second cylinder body 3, the second connecting ring 602 being in contact with the first connecting ring 6, an externally threaded collar 603 arranged on the second connecting ring 602, the internally threaded collar 601 being threadedly sleeved on the externally threaded collar 603, a toothed ring 604 arranged on the first connecting ring 6, a locking motor 605 arranged on the top side of the movable seat 4, a gear 606 arranged on the output end of the locking motor 605 for transmission, the gear 606 being meshed with the toothed ring 604, a limiting component arranged on the second connecting ring 602 for preventing the internally threaded collar 601 from rotating and loosening, two support components arranged on the base 1 and the movable seat 4 for supporting the first cylinder body 2 and the second cylinder body 3, a plurality of positioning holes 614 for positioning the output end of the electric push rod 504 are formed on both the first connecting ring 6 and the second connecting ring 602, the output end of the electric push rod 504 corresponds to one of the positioning holes 614, the positioning hole 614 corresponds to the L-shaped lifting plate 5, flipping the clamping jaws 608 on both sides to disengage them from the clamping grooves 607 can release the restriction on the internally threaded collar 601, and then the locking motor 605 can be started to drive the gear 606 to rotate. The rotating gear 606 can drive the internally threaded collar 601 to rotate. During the rotation of the internally threaded collar 601, it can move on the externally threaded collar 603 and gradually loosen.

[0072] Among them, the limiting component includes a clamping groove 607 formed on the internally threaded collar 601 for positioning, two clamping jaws 608 respectively located in the two clamping grooves 607, two rotating shafts 609 respectively rotatably mounted on the inner walls of the two clamping jaws 608 to provide a rotation fulcrum for the clamping jaws 608, two mounting seats 610 arranged on the second connecting ring 602, the two rotating shafts 609 are respectively fixedly mounted on the two mounting seats 610, two torsion springs 611 sleeved on the two rotating shafts 609, one ends of the two torsion springs 611 are respectively fixedly mounted on the inner walls of the two clamping jaws 608, and the other ends of the two torsion springs 611 are respectively fixedly mounted on the two rotating shafts 609, an extrusion inclined surface 615 formed on the internally threaded collar 601 for extruding the two clamping jaws 608. During the flipping process of the clamping jaws 608, they can rotate on the rotating shafts 609 and compress the torsion springs 611. When it is necessary to combine the first cylinder body 2 and the second cylinder body 3, by controlling the output end of the adjusting motor 802 to rotate in the reverse direction, the first cylinder body 2 can be driven to move back to its original position. Starting the locking motor 605 to make its output end rotate in the reverse direction can drive the internally threaded collar 601 to be screwed onto the externally threaded collar 603 again. During this process, the extrusion inclined surface 615 will extrude the corresponding clamping jaw 608 to make it flip. Finally, when the internally threaded collar 601 is completely screwed onto the externally threaded collar 603, the clamping jaw 608 is no longer extruded by the extrusion inclined surface 615, and under the action of the torsion spring 611, it can flip back to its original position and be stuck in the clamping groove 607 to prevent the internally threaded collar 601 from rotating and loosening in the reverse direction.

[0073] Among them, the support assembly includes two reinforcing seats 612 arranged on the base 1 and the movable seat 4, a plurality of support rollers 613 respectively arranged on the two reinforcing seats 612, and two support rollers 613 on the same side are respectively in contact with the first cylinder body 2 and the second cylinder body 3. By providing the reinforcing seats 612 and the support rollers 613, support can be provided for the first cylinder body 2 or the second cylinder body 3.

[0074] Among them, the adjustment structure includes a threaded slider 8 arranged on the bottom side of the movable seat 4. The threaded slider 8 is slidably installed on the inner wall of the base 1, an adjustment screw rod 801 threadedly installed on the threaded slider 8. The adjustment screw rod 801 is rotatably installed on the inner wall of the base 1, an adjustment motor 802 arranged on one side of the base 1 and used to drive the adjustment screw rod 801 to rotate. The output end of the adjustment motor 802 is fixedly installed at one end of the adjustment screw rod 801, and a plurality of pulleys 803 rotatably installed on the inner wall of the base 1 to make the movement of the movable seat 4 smoother. The pulleys 803 are in contact with the bottom side of the movable seat 4. By turning on the adjustment motor 802, the adjustment screw rod 801 can be driven to rotate. When the adjustment screw rod 801 rotates, the threaded slider 8 can be driven to slide horizontally. The sliding threaded slider 8 drives the movable seat 4 to move. When the movable seat 4 moves, the pulleys 803 at the bottom can be driven to rotate, making the movement of the movable seat 4 smoother. The continuously moving movable seat 4 can drive the first cylinder body 2 to move through the roller seat 7, and further drive the first connecting ring 6 and the internal thread sleeve ring 601 to move by the first cylinder body 2.

[0075] Working principle: When the crushing cone column 501 in the first cylinder body 2 and the second cylinder body 3 is worn during use, the electric push rods 504 on both sides can be opened so that their output ends abut against the first connecting ring 6 and the second connecting ring 602, thereby limiting the first cylinder body 2 and the second cylinder body 3. Then, the clamping jaws 608 on both sides are flipped to disengage them from the clamping grooves 607, thus releasing the restriction on the internal thread sleeve ring 601. Among them, during the flipping process, the clamping jaws 608 can rotate on the rotating shaft 609 and compress the torsion spring 611. Then, the locking motor 605 can be turned on, and the output end of the locking motor 605 can drive the gear 606 to rotate. The rotating gear 606 can drive the internal thread sleeve ring 601 to rotate through meshing with the toothed ring 604. During the rotation process, the internal thread sleeve ring 601 rotates on the external thread sleeve ring 603. At the same time, through the thread fit between the internal thread sleeve ring 601 and the external thread sleeve ring 603, the internal thread sleeve ring 601 can move on the external thread sleeve ring 603 and gradually loosen while rotating. During this process, the adjustment motor 802 can be synchronously turned on, and the output end of the adjustment motor 802 can drive the adjustment screw 801 to rotate. When the adjustment screw 801 rotates, it can drive the thread slider 8 to slide horizontally through the thread fit with the thread slider 8. The sliding thread slider 8 drives the movable seat 4 to move. When the movable seat 4 moves, it can drive the pulley 803 at the bottom to rotate, making the movement of the movable seat 4 smoother during the movement process. The continuously moving movable seat 4 can drive the first cylinder body 2 to move through the roller seat 7, thereby enabling the first cylinder body 2 to drive the first connecting ring 6 and the internal thread sleeve ring 601 to move, so as to be able to cooperate with the rotation of the internal thread sleeve ring 601 to drive the internal thread sleeve ring 601 to move, causing it to loosen from the external thread sleeve ring 603, thereby releasing the connection between the first cylinder body 2 and the second cylinder body 3. Continuously moving the first cylinder body 2 can expose the interiors of the first cylinder body 2 and the second cylinder body 3, facilitating maintenance. When it is necessary to replace the worn crushing cone column 501, the first cylinder body 2 and the second cylinder body 3 can be rotated to adjust their angles so that the L-shaped lifting plate 5 installed on the worn crushing cone column 501 is aligned with the output end of the electric push rod 504 in the positioning hole 614. Then, the electric push rod 504 is turned on, and its output end can extend into the positioning hole 614 and contact the L-shaped lifting plate 5, finally ejecting the L-shaped lifting plate 5 from the first cylinder body 2 or the second cylinder body 3 to complete the disassembly of the L-shaped lifting plate 5 and the crushing cone column 501. A new intact L-shaped lifting plate 5 and crushing cone column 501 can be replaced for use.

[0076] When it is necessary to combine the first cylinder body 2 and the second cylinder body 3, the output end of the control adjustment motor 802 can be driven to rotate in the reverse direction to drive the first cylinder body 2 to move back to its original position. When the reset first cylinder body 2 drives the internal thread collar 601 to sleeved on the external thread collar 603 again, the locking motor 605 is started to make its output end rotate in the reverse direction, driving the internal thread collar 601 to screw on the external thread collar 603 again. During the process, the extrusion inclined surface 615 on the internal thread collar 601 will extrude the corresponding clamp 608, causing the clamp 608 to be pressed and flipped. Finally, the internal thread collar 601 is completely screwed on the external thread collar 603. During the process, the first cylinder body 2 and the second cylinder body 3 will be in close contact. At the same time, the clamp 608 is no longer extruded by the extrusion inclined surface 615 and the internal thread collar 601. The clamp 608 can be flipped back to its original position under the action of the torsion spring 611 and stuck in the clamping groove 607 to prevent the internal thread collar 601 from rotating in the reverse direction and loosening, improving stability. When the first cylinder body 2 and the second cylinder body 3 perform abrasive processing on quartz sand, they will rotate. During the process, the corresponding support rollers 613 will be driven to rotate on the reinforcement base 612. By setting the reinforcement base 612 and the support rollers 613, support can be provided for the first cylinder body 2 or the second cylinder body 3, and at the same time, their rotation effect will not be affected.

[0077] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
