Description

Technical Field

[0001] The present invention belongs to the technical field of crushing devices, and in particular relates to a river channel sand and gravel crushing processing device and a use method thereof. Background Art

[0002] The river sedimentation process is mainly affected by multiple factors such as terrain slope, sediment type and sediment transport, river flow and flow pattern, and vegetation. The river sand and gravel are constantly transported and accumulated during the flow of water, thus forming sand sediments with certain sedimentary characteristics. Before use, the river sand and gravel need to be crushed to meet the use requirements.

[0003] The existing sand and gravel crushing and processing device includes an adjusting crushing mechanism and an executing crushing mechanism. The adjusting crushing mechanism can complete the primary crushing of sand and gravel by a step-by-step crushing method during operation, and the executing crushing mechanism can perform batch quantitative extrusion crushing on the sand and gravel that has undergone primary crushing during operation. The batch quantitative method can limit the amount of sand and gravel extruded and crushed in a single time, and can ensure that the specifications of the sand and gravel after multi-stage crushing meet the production requirements.

[0004] The regulating crushing mechanism and the executing crushing mechanism in the existing device both use extrusion to complete the crushing of sand and gravel. Although this extrusion crushing method can complete the crushing of sand and gravel, its crushing technical means are single. In order to ensure that the sand and gravel can reach the required crushed size, a lot of crushing time is required, resulting in poor crushing efficiency and crushing quality.

[0013] External rolling blocks are fixed vertically and equidistantly on the inner wall of the outer cylinder, and a rolling tooth plate is fixed at the bottom of the external rolling blocks; and

[0014] The inner rolling blocks are fixed on the outer wall of the inner cylinder at equal intervals vertically, and a rolling tooth plate is fixed on the top of the inner rolling blocks.

[0017] As a further technical solution of the present invention, the driving mechanism comprises:

[0018] A driving motor fixed on the tripod, wherein a driving shaft is fixed on the output end of the driving motor;

[0019] A first main shaft installed on the centrifugal crushing device, one end of the first main shaft extends to the top of the centrifugal crushing device and is connected to the drive shaft through a transmission member, the other end of the first main shaft extends to the bottom of the centrifugal crushing device, and a first connecting key is fixed on the outer wall of the other end of the first main shaft;

[0024] A method for using the river channel sand and gravel crushing and processing device as described above, the specific steps are as follows:

[0025] 1. The driving motor drives the driving shaft to rotate, and the driving shaft drives the first main shaft to rotate through the transmission member, and the first main shaft drives the centrifugal crushing device to rotate. The centrifugal crushing device completes the primary crushing of sand and gravel by rotating. The sand and gravel after primary crushing are transported to the space between the outer cylinder and the inner cylinder through the guide plate;

[0026] Second, the first main shaft drives the connecting cylinder to rotate through the first connecting key, the connecting cylinder drives the second main shaft to rotate through the second connecting key, the second main shaft drives the inner cylinder to rotate, the inner cylinder drives the inner rolling block and the inner bracket to rotate synchronously, and the inner rolling block stirs the sand and gravel between the two by rotating and cooperating with the outer rolling block;

[0027] 3. The inner bracket drives the fixed cylinder to rotate, the fixed cylinder drives the connecting frame to rotate through the fixed column, and the connecting frame drives the pulley to rotate on the control member. When the pulley slides to the convex point, the fixed column drives the inner bracket to rise to the highest point through the nut, and the inner bracket drives the inner cylinder and the inner rolling block thereon to rise to the highest point. At this time, the inner cylinder squeezes the spring to make it in a force storage state. When the pulley slides to the concave point, the spring drives the inner cylinder to descend by releasing its own elastic force, and the inner cylinder drives the inner bracket to move downward. Both the inner bracket and the inner cylinder drop to the lowest point, and the pulley drives the inner bracket to reciprocate by sliding back and forth between the concave point and the convex point, and the inner bracket drives the inner cylinder in the rotating state to reciprocate.

[0028] 3. When the inner cylinder rises inside the outer cylinder, the distance between the inner rolling block and the outer rolling block is reduced. Since the inner cylinder moves upward synchronously and the position of the outer cylinder is always fixed, the rolling space surrounded by the rolling block, the inner rolling block, the outer cylinder and the inner cylinder is reduced. The inner rolling block and the inner cylinder roll the sand and gravel vertically and rollingly by synchronous rotation and synchronous rise;

[0029] 4. When the inner cylinder descends inside the outer cylinder, the distance between the inner rolling block and the outer rolling block increases. At the same time, the inner rolling block and the inner cylinder rotate synchronously, and the sand and gravel between them fall quickly to between the next group of inner rolling blocks and outer rolling blocks. Since the rolling space around each group of inner rolling blocks, inner rolling blocks, outer cylinder and inner cylinder is inconsistent, the next group of inner rolling blocks and outer rolling blocks roll the sand and gravel again by rising and complete the advanced crushing of the sand and gravel.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The driving mechanism can simultaneously drive the centrifugal crushing device and the inner cylinder to rotate by rotating. The centrifugal crushing device can complete the primary crushing of sand and gravel by rotating, and the sand and gravel after the primary crushing can be transported to between the outer cylinder and the inner cylinder through the guide plate;

[0032] The way that the inner cylinder rotates inside the outer cylinder can not only stir the sand and gravel between the two, so that it will not easily cause blockage and other problems between the two, ensuring the crushing efficiency and crushing quality of the sand and gravel, but also drive the inner bracket at the bottom to rotate synchronously, and the inner bracket drives the other end of the reciprocating lifting mechanism to rotate, and the other end of the reciprocating lifting mechanism can drive the inner bracket to reciprocate and rise and fall by rotating and cooperating with one end fixed on the outer bracket. The inner bracket drives the inner cylinder in the rotating state to reciprocate and rise and fall, so that the inner cylinder can stir the sand and gravel between it and the outer cylinder at the same time, and can also roll the sand and gravel between the two by reciprocating lifting, thereby realizing vertical rolling and rolling rolling of the sand and gravel, thereby completing the high-level crushing of the sand and gravel, crushing it to the required size, and then continuously crushing the sand and gravel, which can not only effectively ensure the crushing quality of the sand and gravel, but also significantly shorten the time required for the entire crushing process, and at the same time, it is convenient to transport the sand and gravel or carry out subsequent processing thereof, significantly improving the crushing efficiency and crushing quality of the device.

[0046] The crushing device 700 is mounted on the main frame 100 and is located directly below the centrifugal crushing device 400. The crushing device 700 includes an outer cylinder 710, an inner cylinder 720, an inner bracket 750 and an outer bracket 760. The inner cylinder 720 is located inside the outer cylinder 710. The outer wall of the outer cylinder 710 is fixedly connected to the main frame 100. The outer bracket 760 is fixed on the inner wall of the bottom of the outer cylinder 710. The outer bracket 760 is rotatably connected to the other end of the driving mechanism 300. A guide plate 600 is provided between the top and the discharge port of the centrifugal crushing device 400, and the two ends of the guide plate 600 are respectively fixed on the top of the outer cylinder 710 and the main frame 100, and an inner bracket 750 is fixed to the inner wall of the bottom of the inner cylinder 720, and the top of the inner cylinder 720 is closed, and the top of the inner cylinder 720 and the inner bracket 750 are both vertically slidably connected to the other end of the driving mechanism 300, and the outer cylinder 710 and the inner cylinder 720 are both a cone structure, and the inclination angles of the outer cylinder 710 and the inner cylinder 720 on the end faces close to each other are different;

[0047] A reciprocating lifting mechanism 800, wherein the reciprocating lifting mechanism 800 is located between the inner support 750 and the outer support 760, wherein one end of the reciprocating lifting mechanism 800 is fixed to the outer support 760, and the other end of the reciprocating lifting mechanism 800 is mounted on the inner support 750;

[0048] The driving mechanism 300 can simultaneously drive the centrifugal crushing device 400 and the inner cylinder 720 to rotate by rotating. The centrifugal crushing device 400 can complete the primary crushing of sand and gravel by rotating, and the sand and gravel after the primary crushing can be transported to between the outer cylinder 710 and the inner cylinder 720 through the guide plate 600.

[0049] The inner cylinder 720 rotates inside the outer cylinder 710, which can not only stir the sand and gravel between the two, so that it will not easily get blocked between the two, ensuring the crushing efficiency and crushing quality of the sand and gravel, but also drive the inner bracket 750 at the bottom to rotate synchronously, and the inner bracket 750 drives the other end of the reciprocating lifting mechanism 800 to rotate, and the other end of the reciprocating lifting mechanism 800 can drive the inner bracket 750 to reciprocate and rise and fall by rotating and cooperating with one end fixed on the outer bracket 760. The inner bracket 750 drives the inner cylinder 720 in a rotating state to reciprocate and rise and fall, so that the inner cylinder 720 can not only stir the sand and gravel between it and the outer cylinder 710, but also crush the sand and gravel between the two by reciprocating lifting, thereby completing the advanced crushing of the sand and gravel, crushing it to the required size, facilitating the transportation of the sand and gravel or subsequent processing thereof, significantly improving the crushing efficiency and crushing quality of the device, and continuously crushing the sand and gravel, which can not only effectively ensure the crushing quality of the sand and gravel, but also significantly shorten the time required for the entire crushing process.

[0050] In this embodiment, a rotating disk is provided inside the centrifugal crushing device 400, and crushing pendulums are evenly distributed on the rotating disk. The crushing pendulums can perform primary crushing of the sand and gravel in the centrifugal crushing device 400 by centrifugal rotation.

[0051] The guide plate 600 is preferably formed by two semicircular arc plates locked together, which can effectively and quickly guide the sand and gravel discharged from the discharge port of the centrifugal crushing equipment 400 to the interior of the rolling crushing equipment 700.

[0052] like Figures 3 to 7 As shown, as a preferred embodiment of the present invention, the rolling and crushing equipment 700 also includes an outer rolling block 730, an inner rolling block 740 and a rolling tooth plate 770, the outer rolling block 730 is vertically equidistantly fixed on the inner wall of the outer cylinder 710, the inner rolling block 740 is vertically equidistantly fixed on the outer wall of the inner cylinder 720, and the bottom of the outer rolling block 730 and the top of the inner rolling block 740 are both fixed with a rolling tooth plate 770.

[0053] like Figures 3 to 7 As shown, as a preferred embodiment of the present invention, the outer rolling block 730 and the inner rolling block 740 both preferably adopt an annular block structure composed of two semicircles, and the side of the top of the outer rolling block 730 close to the inner rolling block 740 is an inclined end face, and the side of the bottom of the inner rolling block 740 close to the outer rolling block 730 is an inclined end face, which can facilitate the movement of sand and gravel between the outer rolling block 730 and the inner rolling block 740.

[0054] In this embodiment, the inner cylinder 720 drives the inner rolling block 740 and the inner bracket 750 to rotate synchronously. The inner rolling block 740 can stir the sand and gravel between the two by rotating and cooperating with the outer rolling block 730, so that it will not easily cause blockage and other problems between the two, thereby ensuring the crushing efficiency and crushing quality of the sand and gravel;

[0055] The inner bracket 750 drives the other end of the reciprocating lifting mechanism 800 to rotate. The other end of the reciprocating lifting mechanism 800 can drive the inner bracket 750 to reciprocate and lift by rotating and cooperating with one end fixed on the outer bracket 760. The inner bracket 750 drives the inner cylinder 720 in a rotating state to reciprocate and lift. The inner cylinder 720 drives the inner rolling block 740 thereon to reciprocate and lift synchronously. The inner rolling block 740 can roll the sand and gravel between the two by reciprocating and lifting and cooperating with the outer rolling block 730, thereby completing the high-level crushing of the sand and gravel to the required size, facilitating the transportation of the sand and gravel or the subsequent processing thereof, significantly improving the crushing efficiency and crushing quality of the device, and continuously crushing the sand and gravel, which can not only effectively ensure the crushing quality of the sand and gravel, but also significantly shorten the time required for the entire crushing process;

[0056] When the inner cylinder 720 descends inside the outer cylinder 710, the distance between the inner rolling block 740 and the outer rolling block 730 continues to expand. At the same time, the inner rolling block 740 and the inner cylinder 720 rotate synchronously, which can help the sand and gravel between the two to fall quickly to the next group of inner rolling blocks 740 and outer rolling blocks 730. Since the rolling space surrounded by each group of inner rolling blocks 740, inner rolling blocks 740, outer cylinder 710 and inner cylinder 720 is inconsistent, the next group of inner rolling blocks 740 and outer rolling blocks 730 can be rolled again by rising, thereby completing the multi-stage crushing treatment of sand and gravel, and then completing the advanced crushing of sand and gravel, improving the crushing efficiency and crushing quality of the device for sand and gravel;

[0057] When the inner cylinder 720 rises inside the outer cylinder 710, the distance between the inner rolling block 740 and the outer rolling block 730 is continuously reduced. Since the inner cylinder 720 moves upward synchronously while the outer cylinder 710 is always in a fixed position, the rolling space surrounded by the rolling blocks, the inner rolling block 740, the outer cylinder 710 and the inner cylinder 720 is continuously reduced, so that the inner rolling block 740 and the outer rolling block 730 can roll and crush the sand and gravel in the rolling space, and the inner rolling block 740 and the inner cylinder 720 rotate synchronously, so that the inner rolling block 740 and the outer rolling block 730 can not only vertically roll the sand and gravel to crush it, but also roll and roll it by rotating, thereby ensuring the rolling efficiency and rolling quality of the sand and gravel, and further improving the crushing quality and crushing efficiency of the device for sand and gravel.

[0058] In a preferred embodiment, the inner rolling block 740 and the outer rolling block 730 are respectively fixed to the inner cylinder 720 and the outer cylinder 710 by fixing bolts, and installation grooves for their installation are provided at positions corresponding to the inner rolling block 740 and the outer rolling block 730 on the inner cylinder 720 and the outer cylinder 710.

[0059] like Figures 4 to 8 As shown, as a preferred embodiment of the present invention, the reciprocating lifting mechanism 800 includes a fixed cylinder 810, a fixed column 820, a nut 830, a connecting frame 840, a pulley 850 and a control member 860. The fixed cylinder 810 is symmetrically fixed at both ends of the inner bracket 750 along the axis of the inner bracket 750. The fixed column 820 is vertically slidably installed in the fixed cylinder 810. One end of the fixed column 820 is provided with a screw groove that matches the nut 830. The connecting frame 840 is fixed to the other end of the fixed column 820. The nut 830 can be used to fix the fixed column 820 by matching with the screw groove and the connecting frame 840. The fixed column 820 is fixed on the fixed cylinder 810 so that it will not move up and down easily. A pulley 850 is rotatably installed on the connecting frame 840. The pulley 850 is slidably connected to the side wall of the control member 860 fixed on the outer bracket 760. The front and rear ends on the horizontal plane of one end of the control member 860 are set as concave parts 880, and the left and right ends on the horizontal plane of one end of the control member 860 are set as convex parts 870. The height of the convex part 870 is higher than the height of the concave part 880, and the control member 860, the convex part 870 and the concave part 880 are preferably manufactured by an integrated molding process.

[0060] like Figures 4 to 8 As shown, as a preferred embodiment of the present invention, the control member 860 preferably adopts a circular cylindrical structure, and the control member 860 is concentric with the inner bracket 750 and the inner cylinder 720, and the pulley 850 preferably adopts a rotating body with an H-shaped cross-section, and the width of the groove in the middle of the pulley 850 is greater than the wall thickness of the control member 860.

[0061] In this embodiment, the inner bracket 750 drives the fixed cylinder 810 to rotate, and the fixed cylinder 810 drives the connecting frame 840 to rotate through the fixed column 820, and the connecting frame 840 drives the pulley 850 to rotate on the control member 860. When the pulley 850 slides to the convex point portion 870, the fixed column 820 drives the inner bracket 750 to rise to the highest point through the nut 830, and the inner bracket 750 drives the inner cylinder 720 and the inner rolling block 740 thereon to rise to the highest point. When the pulley 850 slides to the concave point position, the fixed column 820 drives the inner bracket 750 to descend to the lowest point through the nut 830, and the inner bracket 750 drives the inner cylinder 720 and the inner rolling block 740 thereon to descend to the lowest point.

[0062] The pulley 850 can drive the inner bracket 750 to rise and fall reciprocally by sliding back and forth between the concave part 880 and the convex part 870. The inner bracket 750 drives the inner cylinder 720 in a rotating state to rise and fall reciprocally. The inner cylinder 720 drives the inner rolling block 740 thereon to rise and fall reciprocally synchronously. The inner rolling block 740 can crush the sand and gravel between the two by reciprocating and rising and cooperating with the outer rolling block 730, thereby completing the high-level crushing of the sand and gravel to the required size, facilitating the transportation of the sand and gravel or its subsequent processing, and significantly improving the crushing efficiency and crushing quality of the device.

[0063] In a preferred embodiment, by changing the threaded position of the nut 830 and the screw groove, the initial position of the fixed column 820 on the fixed cylinder 810 can be changed, thereby changing the initial height of the inner rolling block 740, so that the inner rolling block 740 can roll the sand and gravel to the desired size through reciprocating lifting, rotating and cooperating with the outer rolling block 730, thereby realizing the versatility of the device and improving the applicability and practicality of the device.

[0064] like Figures 1 to 7 As shown in the figure, as a preferred embodiment of the present invention, the driving mechanism 300 includes a driving motor 310, a driving shaft 320, a transmission member 330, a first main shaft 340, a first connecting key 350 and a linkage assembly 360, wherein the driving motor 310 is fixed on the tripod 200, and the driving shaft 320 is fixed on the output end of the driving motor 310, and the first main shaft 340 is installed on the centrifugal crushing device 400, and one end of the first main shaft 340 extends to the top of the centrifugal crushing device 400 and is connected with the driving shaft 320 through the transmission member 330. The other end of the first main shaft 340 extends to the bottom of the centrifugal crushing equipment 400, and a first connecting key 350 is fixed on the outer wall of the other end of the first main shaft 340. The first main shaft 340 and the first connecting key 350 are both connected to one end of a linkage assembly 360. The linkage assembly 360 passes through the crushing equipment 700 and is vertically slidably connected to the inner cylinder 720 and the inner bracket 750 respectively. One end of the linkage assembly 360 is rotatably mounted on the main frame 100, and the other end of the linkage assembly 360 is rotatably mounted on the outer bracket 760.

[0065] In this embodiment, the driving motor 310 drives the driving shaft 320 to rotate, the driving shaft 320 drives the first main shaft 340 to rotate through the transmission member 330, and the first main shaft 340 drives the centrifugal crushing device 400 to rotate. The centrifugal crushing device 400 can complete the primary crushing of sand and gravel by rotating, and the sand and gravel after the primary crushing can be transported to between the outer cylinder 710 and the inner cylinder 720 through the guide plate 600;

[0066] At the same time, the first main shaft 340 can drive the linkage assembly 360 to rotate synchronously through the first connecting key 350, and the linkage assembly 360 drives the inner cylinder 720 to rotate, thereby completing the high-level crushing of sand and gravel, crushing them to the required size, facilitating the transportation of sand and gravel or their subsequent processing, significantly improving the crushing efficiency and crushing quality of the device, and continuously crushing sand and gravel, which can not only effectively guarantee the crushing quality of sand and gravel, but also significantly shorten the time required for the entire crushing process.

[0067] In a preferred embodiment, the transmission member 330 preferably adopts a belt transmission structure composed of a transmission belt and a pulley.

[0068] like Figures 1 to 7 As shown, as a preferred embodiment of the present invention, the linkage assembly 360 includes a coupling cylinder 361, a second main shaft 362, a spring 363 and a second connecting key 364, the coupling cylinder 361 is rotatably mounted on the main frame 100, one end of the coupling cylinder 361 is vertically slidably connected to the first main shaft 340 and the first connecting key 350 respectively, the other end of the coupling cylinder 361 is vertically slidably connected to the second main shaft 362 and the second connecting key 364 respectively, one end of the coupling cylinder 361 is connected to the top of the inner cylinder 720 through the spring 363, the second connecting key 364 is fixed on the outer wall of the second main shaft 362, the second main shaft 362 is vertically slidably connected to the inner bracket 750 and the inner cylinder 720 respectively, and one end of the second main shaft 362 is rotatably mounted on the outer bracket 760.

[0069] In this embodiment, the first main shaft 340 can drive the coupling cylinder 361 to rotate through the first connecting key 350, the coupling cylinder 361 drives the second main shaft 362 to rotate through the second connecting key 364, and the second main shaft 362 drives the inner cylinder 720 to rotate, thereby completing the high-level crushing of sand and gravel;

[0070] When the pulley 850 slides to the convex part 870, the fixed column 820 drives the inner bracket 750 to rise to the highest point through the nut 830, and the inner bracket 750 drives the inner cylinder 720 and the inner rolling block 740 thereon to rise to the highest point. At this time, the inner cylinder 720 squeezes the spring 363 to put it in a force storage state. When the pulley 850 slides to the concave point, the spring 363 drives the inner cylinder 720 to descend by releasing its own elastic force, and the inner cylinder 720 drives the inner bracket 750 to move downward, so that both the inner bracket 750 and the inner cylinder 720 descend to the lowest point.

[0071] like Figures 1 to 8 As shown, as an embodiment of the present invention, a method for using a river channel sand and gravel crushing processing device is provided, and the specific steps are as follows:

[0072] 1. The driving motor 310 drives the driving shaft 320 to rotate, and the driving shaft 320 drives the first main shaft 340 to rotate through the transmission member 330, and the first main shaft 340 drives the centrifugal crushing device 400 to rotate. The centrifugal crushing device 400 can complete the primary crushing of sand and gravel by rotating, and the sand and gravel after the primary crushing can be transported to between the outer cylinder 710 and the inner cylinder 720 through the guide plate 600;

[0073] Second, the first main shaft 340 can drive the coupling cylinder 361 to rotate through the first connecting key 350, and the coupling cylinder 361 drives the second main shaft 362 to rotate through the second connecting key 364, and the second main shaft 362 drives the inner cylinder 720 to rotate, and the inner cylinder 720 drives the inner rolling block 740 and the inner bracket 750 to rotate synchronously. The inner rolling block 740 can stir the sand and gravel between the two by rotating and cooperating with the outer rolling block 730, so that it will not easily cause problems such as blockage between the two, thereby ensuring the crushing efficiency and crushing quality of the sand and gravel;

[0074] 3. The inner bracket 750 drives the fixed cylinder 810 to rotate, and the fixed cylinder 810 drives the connecting frame 840 to rotate through the fixed column 820. The connecting frame 840 drives the pulley 850 to rotate on the control member 860. When the pulley 850 slides to the convex point 870, the fixed column 820 drives the inner bracket 750 to rise to the highest point through the nut 830. The inner bracket 750 drives the inner cylinder 720 and the inner rolling block 740 thereon to rise to the highest point. At this time, the inner cylinder 720 presses the spring 363. The inner bracket 750 is pressed to be in a force storage state. When the pulley 850 slides to the concave point, the spring 363 releases its own elastic force to drive the inner cylinder 720 to descend, and the inner cylinder 720 drives the inner bracket 750 to move downward, so that both the inner bracket 750 and the inner cylinder 720 are dropped to the lowest point. The pulley 850 can drive the inner bracket 750 to rise and fall reciprocatingly by sliding back and forth between the concave point part 880 and the convex point part 870, and the inner bracket 750 drives the inner cylinder 720 in the rotating state to rise and fall reciprocatingly.

[0075] 3. When the inner cylinder 720 rises inside the outer cylinder 710, the distance between the inner rolling block 740 and the outer rolling block 730 is continuously reduced. Since the inner cylinder 720 moves upward synchronously and the position of the outer cylinder 710 is always fixed, the rolling space surrounded by the rolling blocks, the inner rolling block 740, the outer cylinder 710 and the inner cylinder 720 is continuously reduced, so that the inner rolling block 740 and the outer rolling block 730 can roll and crush the sand and gravel in the rolling space, and the inner rolling block 740 and the inner cylinder 720 rotate synchronously, so that the inner rolling block 740 and the outer rolling block 730 can not only vertically roll the sand and gravel to crush it, but also roll and roll it by rotating, thereby ensuring the rolling efficiency and rolling quality of the sand and gravel, and further improving the crushing quality and crushing efficiency of the device for sand and gravel;

[0076] 4. When the inner cylinder 720 descends inside the outer cylinder 710, the distance between the inner rolling block 740 and the outer rolling block 730 continues to expand. At the same time, the inner rolling block 740 and the inner cylinder 720 rotate synchronously, which can help the sand and gravel between the two to fall quickly to between the next group of inner rolling blocks 740 and outer rolling blocks 730. Since the rolling space around each group of inner rolling blocks 740, inner rolling blocks 740, outer cylinder 710 and inner cylinder 720 is inconsistent, the next group of inner rolling blocks 740 and outer rolling blocks 730 can be rolled again by rising, thereby completing the multi-stage crushing process of the sand and gravel, and then completing the advanced crushing of the sand and gravel.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
