Description

Technical Field

[0001] The invention relates to the technical field of crushing equipment, in particular to a granite sandstone processing and classification system. Background Art

[0002] Granite is an intrusive rock among acidic igneous rocks. Its hardness is second only to diamond, and it is one of the hardest rocks on the earth's surface. Granite sand and gravel play an important role in construction and infrastructure construction. It is often used in large-scale high-rise building foundations and road foundation pouring. Because of its high strength and strong adaptability, granite sand and gravel can reduce porosity and save cementitious materials when the particle size is small. Sand and gravel refers to a loose mixture of sand and crushed stone. Mineral or rock particles with a particle size of 0.074 to 2 mm are called sand. If you need to crush granite into sand and gravel, you need to use a crusher.

[0003] Considering that granite is one of the hardest rocks on the earth's surface, its hardness is second only to diamond. The equipment has a large loss when crushing granite, and may cause different degrees of wear due to different usage conditions. In the prior art, the entire equipment is usually replaced during maintenance, and some parts that are not worn or not seriously worn are replaced together, which will increase the use cost of the equipment. Some prior arts use modularization to facilitate disassembly and installation operations. Modularization uses a variety of installation methods, which is not only cumbersome and inconvenient to replace during maintenance, but also because the internal device of the equipment will rotate at high speed during crushing, it will vibrate when in contact with the granite, which is likely to cause loose connection due to vibration. Loose connection may cause the crushing effect to deteriorate, and in severe cases may cause the device to fall off directly and cause damage to the equipment. Summary of the invention

[0004] The object of the present invention is to provide a granite sandstone processing classification system to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a granite sandstone processing and classification system, comprising a crushing shell, the top of the crushing shell is fixedly connected to a puncture shell, the inner wall of the crushing shell is rotatably connected to a crushing mechanism, the inner wall of the crushing shell is fixedly connected to a crushing screen; the outer wall of the puncture shell is fixedly connected to a puncture mechanism, the inner wall of the puncture shell is fixedly connected to a feed screen, and the crushing mechanism comprises a driving unit and a crushing module; The crushing module includes a hammer frame, and there are multiple groups of hammer frames; the inner wall of each group of hammer frames is slidably connected with a counterattack hammer, and there are multiple groups of counterattack hammers; the outer wall of the hammer frame is fixedly connected with a buffer block, and there are multiple groups of buffer blocks; the outer wall of the hammer frame is provided with a disassembly groove, and there are multiple groups of disassembly grooves, and the inner wall of the disassembly groove is slidably connected with the outer wall of the counterattack hammer; the side of the buffer block close to the counterattack hammer is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected with a buffer block; the side of the counterattack hammer that fits with the sliding groove after installation is provided with a connecting groove, and the width of the connecting groove is larger than the sliding groove; the side of the counterattack hammer close to the hammer frame is provided with a rectangular slide groove, and the side of the counterattack hammer close to the rectangular slide groove is provided with a traction The guide groove, the traction groove and the rectangular slide groove are connected to each other; the inner wall of the rectangular slide groove is slidably connected with a pressure block, and there are multiple groups of pressure blocks; the outer wall of the buffer block is slidably connected with the inner wall of the connecting groove when impacted; the bottom of each group of the pressure blocks overlaps the inner wall of the hammer frame, and the outer wall of the pressure block is hinged with two groups of traction links; the inner wall of each group of traction links is hinged with a self-locking block; the outer wall of the self-locking block is slidably connected with the inner wall of the traction groove, the surface of each group of the self-locking blocks is smooth, and the surface of the traction groove is smooth; the weight of the pressure block is greater than the sum of the weights of the two groups of self-locking blocks, and the weight of the counter-attack hammer is greater than the sum of the weights of the pressure block, the traction link and the self-locking block; redundant space is provided inside the disassembly groove.

[0006] By adopting the above technical scheme, when the crushing motor is started, the present invention will engage and fix the hammer frame through the centrifugal force generated by the rotation of the rotating shaft. When not in use, the hammer frame will not be stuck. At this time, the hammer frame can rotate, and the wear of each impact hammer can be checked by rotating the hammer frame to determine whether it needs to be replaced. In order to make the installation of the impact hammer more convenient, the impact hammer will cause the pressure block to move upward during installation, and at the same time, the flat part of the top of the self-locking block will engage with the inner wall of the disassembly groove. In order to prevent the impact hammer from falling off due to excessive centrifugal force during rotation, the buffer block can reduce the impact of the impact hammer during crushing, and the buffer block will be engaged with the hammer frame due to the centrifugal force, so the impact hammer can be prevented from falling off.

[0007] Furthermore, the puncture mechanism includes a driving motor, the bottom of the driving motor is fixedly connected to the outer wall of the puncture shell, and the output end of the driving motor is fixedly connected to a gear turntable; a driving gear is fixedly connected to the center of the inner wall of the gear turntable, and the gear turntable is meshed with a driven gear; a bidirectional screw is fixedly connected to the inner wall of the driven gear; traction plates are threadedly connected to the threads at both ends of the bidirectional screw, and there are two groups of traction plates; a puncture plate is fixedly connected to one side of each group of traction plates close to the gear turntable, and the outer wall of the traction plate is slidably connected to the inner wall of the puncture shell; the outer wall of the puncture plate is slidably connected to the inner wall of the puncture shell, and a puncture block is fixedly connected to one side of the puncture plate close to the gear turntable.

[0008] By adopting the above technical scheme, the present invention causes the two sets of puncture plates to perform repeated clamping actions when the driving motor is started. When contacting with larger granite, the puncture block will perform a puncture operation on the surface of the granite. The puncture operation can destroy the structural stability of the granite itself. The puncture may directly cause cracks on the surface of the granite. The cracked granite cannot withstand the huge impact force when hit and will be broken into multiple small pieces. At this time, the granite can be broken again to avoid damage caused by the granite getting stuck in the equipment, and the wear of the impact hammer can be reduced.

[0009] Furthermore, an impact frame is fixedly connected to the inner wall of the crushing shell; a fixing groove is opened on the outer wall of the impact frame, and there are multiple groups of fixing grooves, and a buffer pad is fixedly installed on the inner wall of the fixing groove; an expansion block is fixedly connected to the side of the buffer pad away from the impact frame, and an impact plate is fixedly installed on the side of the buffer pad away from the impact frame.

[0010] With the above technical solution, considering that the granite will be hit by force during the crushing process, the existing technology cannot provide buffering when the impact plate is hit, which will cause the impact plate to directly transmit the force to the impact frame when it is hit, which may increase the wear of the impact plate and damage the impact frame. If the impact plate is worn, it can be directly replaced, but if the impact frame needs to be replaced, it will increase a lot of maintenance costs; The setting of the buffer pad can reduce the impact on the impact plate, but at the same time the buffer pad will not be too soft to avoid affecting the crushing effect, and can reduce the force of the impact plate on the impact frame, thereby avoiding damage to the impact frame. The impact plate and the buffer pad are fixed to the inner wall of the impact frame by bolts; during the crushing process, the impact of the impact plate will cause the impact plate to vibrate, and the vibration will cause the bolts to loosen. The temperature of the impact plate can be increased by the impact of the granite, and the temperature can be transferred to the expansion block to make the expansion block expand due to heat, so that it squeezes the impact plate and reduces the vibration of the impact plate, thereby avoiding the loosening of the bolts.

[0011] Furthermore, a crushing slide is provided on the inner wall of one side of the crushing shell close to the crushing screen; the surface of the crushing slide is slidably connected to the top of the impact hammer; and the surface of one side of the impact hammer is arc-shaped.

[0012] By adopting the above technical scheme, through the setting of the crushing chute, the larger fragments after crushing can be hooked up by the curved surface of the impact hammer and move upward along the crushing chute. When they reach the top of the hammer frame, they will lose the supporting force and fly out in the axial direction of the hammer frame under the influence of centrifugal force. After flying out, they will collide with the impact plate again, making them smaller fragments, and fall through the screening of the crushing screen.

[0013] Furthermore, the driving unit includes a crushing motor, the output end of the crushing motor is transmission-connected with a transmission belt; the inner wall of the transmission belt is transmission-connected with a rotating shaft; the rotating shaft passes through the outer wall of the crushing shell, the inner wall of the rotating shaft is slidably connected with a connecting block, and there are three groups of connecting blocks, one end of a compression spring is fixedly connected to the surface of the rotating shaft, and there is only one group of compression springs; the inner wall of one group of connecting blocks is fixedly connected to the other end of the compression spring, and the outer wall of the connecting block is fixedly connected with a centrifugal wheel; the inner wall of the hammer frame close to the centrifugal wheel is provided with contact teeth; the outer wall of the centrifugal wheel close to the hammer frame is provided with centrifugal teeth, and the contact teeth and the centrifugal teeth are meshed by centrifugal force.

[0014] By adopting the above technical scheme, the power is transmitted to the rotating shaft by starting the crushing motor to drive the transmission belt. When the rotating shaft rotates, the centrifugal wheel will be thrown out and engaged with the hammer frame due to the influence of centrifugal force. Since there are two connecting blocks without the traction of the compression spring, the engagement point between the centrifugal wheel and the hammer frame will always be the two sets of connecting blocks. When the centrifugal wheel is engaged with the hammer frame, the hammer frame will rotate synchronously. When it is vibrated, it will not separate directly, avoiding the power loss caused by separation due to vibration; when the rotating shaft rotates, the hammer frame will contact with the centrifugal wheel and drive the centrifugal wheel to rotate, but there is a lack of fixation in this process. When vibration occurs during crushing, it may cause the hammer frame to lose contact with the centrifugal wheel. The force area can be increased by setting the contact teeth and the centrifugal teeth. When the contact teeth and the centrifugal teeth are meshed, the contact area will be increased. When it is vibrated, it will not separate directly, avoiding the power loss caused by separation due to vibration; the crushing motor and the rotating shaft are connected by the driving transmission belt, so that the crushing mechanism can be disassembled as a whole during subsequent maintenance, and the vibration or reversal of the crushing mechanism during crushing can prevent the crushing motor from being damaged.

[0015] Furthermore, a feed port is provided on one side of the piercing shell, and the interior of the piercing shell is divided into a fine material chute and a coarse material chute by a feed screen.

[0016] By adopting the above technical scheme, granite is fed through the feed port. When the granite enters the equipment, it will first enter the coarse material chute. The smaller granite can be directly screened out through the feed screen and directly enter the crushing through the fine material chute. The larger fragments will continue to slide down through the coarse material chute and be pierced by the piercing mechanism before being crushed.

[0017] Furthermore, the driving gear is a half gear; the teeth of the gear turntable are distributed in a ring array, and there are three groups of teeth.

[0018] By adopting the above technical solution, the rotation amount of the driven gear in forward and reverse rotation can be made the same through the setting of the teeth of the half gear and the gear turntable, and the forward and reverse interval rotation can be realized. When the driven gear is engaged with the gear turntable, it will rotate clockwise, and when the driven gear is engaged with the driving gear, it will rotate counterclockwise. The driven gear is repeatedly rotated through the tooth interval of the gear turntable and the half gear of the driving gear, so that the subsequent puncture plate can be repeatedly clamped.

[0019] Furthermore, a discharge chamber is arranged inside the crushing shell; a discharge port is opened on one side of the crushing shell, and a slope is arranged at the bottom of the discharge chamber; the slope is inclined from the side away from the discharge port to the discharge port.

[0020] By adopting the above technical scheme, the crushed granite can be discharged through the setting of the discharge chamber and the slope. When it needs to be taken out, the crushed granite inside can be discharged through the discharge port. The slope can make the discharge more convenient and reduce internal residue.

[0021] The present invention has the following beneficial effects: 1. When the crushing motor is started, the centrifugal force generated by the rotation of the rotating shaft will engage and fix the hammer frame. When not in use, the hammer frame will not be stuck. At this time, the hammer frame can rotate, and the wear of each impact hammer can be checked by rotating the hammer frame to determine whether it needs to be replaced. In order to make the installation of the impact hammer more convenient, the impact hammer will cause the pressure block to move upward during installation, and at the same time, the flat part of the top of the self-locking block will engage with the inner wall of the disassembly groove. In order to prevent the impact hammer from falling off due to excessive centrifugal force during rotation, the buffer block can reduce the impact of the impact hammer during crushing, and the buffer block will be engaged with the hammer frame due to the centrifugal force, so the impact hammer can be prevented from falling off.

[0022] 2. When the driving motor is started, the present invention causes the two sets of piercing plates to perform repeated clamping actions. When contacting with a larger granite, the piercing block will perform a piercing operation on the surface of the granite. The piercing operation can destroy the structural stability of the granite itself. During the piercing operation, cracks may appear directly on the surface of the granite. When the cracked granite is hit, it cannot withstand the huge impact force and will be broken into multiple small pieces. At this time, the granite can be broken again to avoid the damage caused by the granite getting stuck in the equipment, and the wear of the counter-attack hammer can be reduced. 3. The present invention can mitigate the impact on the impact plate by setting the buffer pad, but at the same time the buffer pad will not be too soft to avoid affecting the crushing effect, and can reduce the force of the impact plate on the impact frame, thereby avoiding damage to the impact frame. The impact plate and the buffer pad are fixed to the inner wall of the impact frame by bolts; during the crushing process, the impact of the impact plate will cause the impact plate to vibrate, and the vibration will cause the bolts to loosen. The impact of the granite can increase the temperature of the impact plate, and the temperature can be transferred to the expansion block to make the expansion block expand due to heat, so that it squeezes the impact plate and reduces the vibration of the impact plate, thereby avoiding the loosening of the bolts.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In this embodiment, considering that granite is one of the hardest rocks on the earth's surface, and its hardness is second only to diamond, the equipment has a large loss when crushing granite, and may cause different degrees of wear during use due to different usage conditions. In the prior art, the whole is usually replaced during maintenance, and some parts that are not worn or not seriously worn are replaced together, which will increase the use cost of the equipment. Some prior arts use modularization to facilitate disassembly and installation operations. Modularization uses a variety of installation methods, which is not only cumbersome to operate and inconvenient to replace during maintenance, but also because the internal device of the equipment rotates at high speed during crushing, it will vibrate when in contact with the granite, which is likely to cause the connection to loosen due to vibration. The loose connection may cause the crushing effect to deteriorate, and in severe cases, the device may fall off directly and cause damage to the equipment; In order to solve the above problems, the present invention will engage and fix the hammer frame 24 through the centrifugal force generated by the rotation of the rotating shaft 23 when the crushing motor 21 is started. The hammer frame 24 will not be stuck when not in use. At this time, the hammer frame 24 can rotate, and the wear of each impact hammer 25 can be checked by rotating the hammer frame 24 to determine whether it needs to be replaced; in order to make the installation of the impact hammer 25 more convenient, the impact hammer 25 will cause the pressure block 26 to move upward under force during installation, and at the same time, the flat part of the top of the self-locking block 28 will be engaged with the inner wall of the disassembly groove, and in order to prevent the impact hammer 25 from falling off due to excessive centrifugal force during rotation, the buffer block 30 can reduce the impact of the impact hammer 25 during crushing, and the buffer block 30 will be subjected to the centrifugal force and engage with the hammer frame 24, so that the impact hammer 25 can be prevented from falling off; When in use, when the crushing motor 21 is started, the centrifugal force generated by the rotation of the rotating shaft 23 will engage the hammer frame 24 and rotate. When the hammer frame 24 rotates, the impact hammer 25 can be used to crush stones. In order to prevent the impact hammer 25 from being broken due to uneven force due to the small contact area with the hammer frame 24, when the hammer frame 24 rotates, the buffer block 30 will enter the inside of the impact hammer 25 under the influence of gravity and inertia, and when the impact hammer 25 collides with the broken pieces, inertia will be generated. When the impact hammer 25 is subjected to inertia, it will contact with the buffer block 29, and the buffer block 29 can increase the impact of the impact hammer 25. The force area makes the force of the counter-attack hammer 25 more dispersed, and prevents the counter-attack hammer 25 from falling off due to excessive force. At the same time, when the counter-attack hammer 25 shakes due to inertia, the buffer block 30 is pushed to move inside the buffer block 29. The buffering of the buffer block 30 can reduce the direct contact between the counter-attack hammer 25 and the buffer block 29, and avoid the counter-attack hammer 25 breaking due to excessive force when contacting the buffer block 29. In addition, the connection groove is wider than the sliding groove, which can adapt to the redundant space inside the disassembly groove. When the counter-attack hammer 25 moves in the redundant space, the buffer block 30 can also slide inside the counter-attack hammer 25, thereby ensuring the effectiveness of buffering. When the equipment needs to be maintained, the entire equipment is shut down. Since the compression spring 32 is compressed when the centrifugal wheel 33 is engaged with the hammer frame 24, the compression spring 32 will rebound after the rotation stops and push the connecting block 31 to return the centrifugal wheel 33 to its original position. At this time, the centrifugal wheel 33 is not engaged with the hammer frame 24, so that each group of hammer frames 24 can rotate freely. The impact hammers 25 can be arranged by freely rotating the hammer frame 24. When crushing smaller granite, the impact hammers 25 can be dispersedly arranged. Through the staggered impact hammers 25, the granite can be repeatedly struck by different impact hammers 25 during crushing, which increases efficiency and makes wear more uniform, increases the service life of the impact hammers 25, and reduces the replacement frequency. When crushing larger granite, the impact hammers 25 can be arranged in a straight line to achieve the best stability, avoid excessive dispersion resulting in poor crushing effect, and even increase the wear of the impact hammers 25. The counter-attack hammer 25 can be checked by rotating the hammer rack 24 counterclockwise. Since the weight of the counter-attack hammer 25 after wear is lower than that of the relatively intact counter-attack hammer 25, the heavier counter-attack hammer 25 will be rotated to the bottom of the hammer rack 24 due to gravity. Therefore, the severely worn counter-attack hammer 25 will usually be at the top of the hammer rack 24. When a severely worn counter-attack hammer 25 is found, the hammer rack 24 can be rotated counterclockwise so that the buffer block 30 is subjected to gravity and enters the interior of the buffer card block 29, and the counter-attack hammer 25 can be directly pulled out. Since redundant space is provided in the disassembly groove, when the upward pulling force of the counter-attack hammer 25 causes the self-locking card block 28 to move upward in the redundant space, and there will be extra space at the bottom of the disassembly groove, which can be used for the counter-attack hammer 25. The pressure block 26 is subjected to gravity and moves downward autonomously. When the pressure block 26 moves downward, it pulls the self-locking block 28 to move inward, and when the self-locking block 28 contacts the top of the disassembly groove, it is pushed downward by the disassembly groove. Since the top of the self-locking block 28 is inclined, the self-locking block 28 is further retracted into the inside of the hammer frame 24 when it is pushed. When the self-locking block 28 is completely retracted into the inside of the hammer frame 24, the counter-attack hammer 25 can be taken out. Since the length of the pressure block 26 is the same as that of the self-locking block 28, the pressure block 26 can be pushed into the inside of the traction groove after the counter-attack hammer 25 is taken out. At this time, the pressure block 26, the traction connecting rod 27 and the self-locking block 28 can be taken out and installed into the inside of the new counter-attack hammer 25. When installing the counter-attack hammer 25, since the gravity of the counter-attack hammer 25 is heavier than the pressure block 26, the traction link 27 and the self-locking block 28, when the counter-attack hammer 25 enters the disassembly groove, the pressure block 26 will contact the bottom of the disassembly groove and be forced to move upward. When the pressure block 26 moves upward, the traction link 27 will pull the self-locking block 28 to move outward. When the self-locking block 28 enters the interior of the hammer frame 24, it will engage with the hammer frame 24 through the plane at the top of the self-locking block 28, and the counter-attack hammer 25 can be fixed at this time; when the counter-attack hammer 25 is at the bottom of the hammer frame 24, the pressure block 26 will enter the interior of the rectangular slide groove due to gravity. When the pressure block 26 enters, the self-locking block 28 will completely enter the interior of the disassembly groove and make it completely fit with both sides of the disassembly groove, thereby avoiding the counter-attack hammer 25 being affected by gravity when it is at the bottom of the hammer frame 24. Since there is redundant space for the movement of the self-locking block 28, the granite will continuously hit the impact hammer 25 during the crushing operation, which will generate a downward pressure on the impact hammer 25. At the same time, since there is redundant space at the bottom of the pressure plate for taking out, when the pressing block 26 is under pressure, it can be further inserted into the interior of the impact hammer 25, and the self-locking block 28 is pulled by the traction link 27 to make the engagement between the self-locking block 28 and the impact hammer 25 more secure. When crushing, the impact hammer 25 will be subjected to the reaction force of the broken pieces, which will cause the self-locking block 28 to generate inertia. When one group of the self-locking blocks 28 is moved by gravity and inertia, it will pull the traction link 27 and move the pressing block 26 upward. When the pressing block 26 moves upward, it will also move the other group of self-locking blocks 28 outward, thereby increasing stability.

[0030] Specifically, the puncture mechanism 4 includes a driving motor 41, the bottom of the driving motor 41 is fixedly connected to the outer wall of the puncture shell 11, and the output end of the driving motor 41 is fixedly connected to a gear turntable 42; a driving gear 43 is fixedly connected to the center of the inner wall of the gear turntable 42, and the gear turntable 42 is meshed with a driven gear 44; a bidirectional screw rod 45 is fixedly connected to the inner wall of the driven gear 44; traction plates 46 are threadedly connected to the threads at both ends of the bidirectional screw rod 45, and there are two groups of traction plates 46; each group of traction plates 46 is fixedly connected to a puncture plate 47 on one side close to the gear turntable 42, and the outer wall of the traction plate 46 is slidably connected to the inner wall of the puncture shell 11; the outer wall of the puncture plate 47 is slidably connected to the inner wall of the puncture shell 11, and a puncture block is fixedly connected to the one side of the puncture plate 47 close to the gear turntable 42.

[0031] In this embodiment, it is considered that when encountering a large granite, directly using the device to crush it may result in failure to crush it. When it cannot be crushed, the granite may be directly stuck in the internal device, thereby causing damage to the equipment. Even if the large granite can be crushed, it needs to hit the granite multiple times during the crushing process, which will greatly increase the wear of the impact hammer 25. In order to solve the above problems, when the driving motor 41 is started, the present invention causes the two sets of puncture plates 47 to perform repeated clamping actions. When contacting with larger granite, the puncture blocks will perform puncture operations on the surface of the granite. The puncture operation can destroy the structural stability of the granite itself. The puncture may directly cause cracks on the surface of the granite. The cracked granite cannot withstand the huge impact force when hit and will be broken into multiple small pieces. At this time, the granite can be broken again to avoid damage caused by the granite getting stuck in the equipment, and the wear of the impact hammer 25 can be reduced.

[0032] The drive motor 41 is started to rotate the gear disc 42. When the gear disc 42 rotates, the driving gear 43 and the driven gear 44 are rotated. When the driven gear 44 is meshed with the gear disc 42, it will rotate clockwise. When the driven gear 44 is meshed with the driving gear 43, it will rotate counterclockwise. The driven gear 44 is repeatedly rotated through the tooth interval of the gear disc 42 and the half gear of the driving gear 43. When the driven gear 44 rotates, it drives the bidirectional screw rod 45 to rotate. Through the bidirectional thread on the bidirectional screw rod 45 The two groups of traction plates 46 can be made to reciprocate, and the puncture plates 47 can be pushed or pulled to reciprocate while the traction plates 46 are reciprocating. When the puncture plates 47 are clamped, the granite is punctured, and the overall structural stability of the granite can be destroyed. When the granite is subsequently crushed, it will contact the impact hammer 25 and be impacted by the impact hammer 25, and it will be directly broken into multiple small pieces. At this time, further crushing can reduce the wear of the impact hammer 25, and at the same time, it can prevent larger granite from getting stuck in the equipment, thereby causing damage to the equipment.

[0033] Specifically, an impact frame 16 is fixedly connected to the inner wall of the crushing shell 1; a fixing groove is opened on the outer wall of the impact frame 16, and there are multiple groups of fixing grooves, and a buffer pad 18 is fixedly installed on the inner wall of the fixing groove; an expansion block 19 is fixedly connected to the side of the buffer pad 18 away from the impact frame 16, and an impact plate 17 is fixedly installed on the side of the buffer pad 18 away from the impact frame 16.

[0034] In this embodiment, considering that the granite will be hit by force during the crushing process, the impact plate 17 cannot be buffered in the prior art when the impact plate 17 is hit, which will cause the impact plate 17 to directly transmit the force to the impact frame 16 when it is hit, which may increase the wear of the impact plate 17 and damage the impact frame 16. If the impact plate 17 is worn, it can be directly replaced, but if the impact frame 16 needs to be replaced, it will increase a lot of maintenance costs; The setting of the buffer pad 18 can reduce the impact on the impact plate 17, but at the same time the buffer pad 18 will not be too soft to avoid affecting the crushing effect, and can reduce the force of the impact plate 17 on the impact frame 16, thereby avoiding damage to the impact frame 16. The impact plate 17 and the buffer pad 18 are fixed to the inner wall of the impact frame 16 by bolts; during the crushing process, the impact of the impact plate 17 will cause the impact plate 17 to vibrate, and the vibration will cause the bolts to loosen. The temperature of the impact plate 17 can be increased by the impact of the granite, and the expansion block 19 can be heated and expanded by transferring the temperature to the expansion block 19, so that it squeezes the impact plate 17 and reduces the vibration of the impact plate 17, thereby avoiding the loosening of the bolts.

[0035] Specifically, a crushing slide is provided on the inner wall of one side of the crushing shell 1 close to the crushing screen 13; the surface of the crushing slide is slidably connected to the top of the impact hammer 25; and the surface of one side of the impact hammer 25 is arc-shaped.

[0036] In this embodiment, the setting of the crushing chute can make the larger fragments after crushing be hooked up by the arc surface of the impact hammer 25 and move upward along the crushing chute. When reaching the top of the hammer frame 24, they will lose the supporting force and fly out in the axial direction of the hammer frame 24 under the influence of centrifugal force. After flying out, they will collide with the impact plate 17 again, making them smaller fragments, and fall through the screening of the crushing screen 13.

[0037] Specifically, the driving unit includes a crushing motor 21, and the output end of the crushing motor 21 is transmission-connected with a transmission belt 22; the inner wall of the transmission belt 22 is transmission-connected with a rotating shaft 23; the rotating shaft 23 passes through the outer wall of the crushing shell 1, and the inner wall of the rotating shaft 23 is slidably connected with a connecting block 31, and there are three groups of connecting blocks 31, and the surface of the rotating shaft 23 is fixedly connected with one end of a compression spring 32, and there is only one group of compression springs 32; the inner wall of one group of connecting blocks 31 is fixedly connected to the other end of the compression spring 32, and the outer wall of the connecting block 31 is fixedly connected with a centrifugal wheel 33; the inner wall of the hammer frame 24 close to the centrifugal wheel 33 is provided with contact teeth; the outer wall of the centrifugal wheel 33 close to the hammer frame 24 is provided with centrifugal teeth, and the contact teeth and the centrifugal teeth are meshed by centrifugal force.

[0038] In this embodiment, the crushing motor 21 is started to drive the transmission belt 22 to transmit power to the rotating shaft 23. When the rotating shaft 23 rotates, the centrifugal wheel 33 will be thrown out and engaged with the hammer frame 24 due to the influence of centrifugal force. Since there are two connecting blocks 31 without the traction of the compression spring 32, the engaging point between the centrifugal wheel 33 and the hammer frame 24 will always be the two sets of connecting blocks 31. When the centrifugal wheel 33 is engaged with the hammer frame 24, the hammer frame 24 will rotate synchronously. When vibrated, it will not separate directly, avoiding power loss caused by separation due to vibration; when the rotating shaft 23 rotates, the hammer frame 24 will contact with the centrifugal wheel 33, and The centrifugal wheel 33 is driven to rotate, but there is a lack of fixation in the process. When vibration occurs during crushing, the hammer frame 24 may lose contact with the centrifugal wheel 33. The force-bearing area can be increased by setting the contact teeth and the centrifugal teeth. When the contact teeth and the centrifugal teeth are meshed, the contact area will increase. When vibrated, they will not separate directly, avoiding power loss caused by separation due to vibration. The crushing motor 21 and the rotating shaft 23 are connected by a driving belt 22, so that the crushing mechanism 2 can be disassembled as a whole during subsequent maintenance, and the vibration or reversal of the crushing mechanism 2 during crushing can prevent damage to the crushing motor 21.

[0039] Specifically, a feed port is opened on one side of the piercing shell 11, and the interior of the piercing shell 11 is divided into a fine material chute and a coarse material chute by a feed screen 12.

[0040] In this embodiment, granite is fed through the feed port. When the granite enters the equipment, it will first enter the coarse material chute. The smaller granite can be directly screened out through the feed screen 12 and directly enter the crushing through the fine material chute. The larger fragments will continue to slide down through the coarse material chute and be pierced by the piercing mechanism 4 before being crushed.

[0041] Specifically, the driving gear 43 is a half gear; the teeth of the gear rotating disk 42 are distributed in a ring array, and there are three groups of teeth.

[0042] In this embodiment, the teeth of the half gear and the gear turntable 42 are arranged so that the rotation amount of the driven gear 44 in the forward and reverse rotations can be the same, and the forward and reverse interval rotation can be realized. When the driven gear 44 is engaged with the gear turntable 42, it will rotate clockwise, and when the driven gear 44 is engaged with the driving gear 43, it will rotate counterclockwise. The driven gear 44 is repeatedly rotated through the tooth interval of the gear turntable 42 and the half gear of the driving gear 43, so that the subsequent puncture plate 47 can perform repeated clamping operations.

[0043] Specifically, a discharge chamber 15 is provided inside the crushing shell 1 ; a discharge port 14 is provided on one side of the crushing shell 1 , and a slope is provided at the bottom of the discharge chamber 15 ; the slope is inclined from the side away from the discharge port 14 to the discharge port 14 .

[0044] In this embodiment, the crushed granite can be discharged through the setting of the discharge chamber 15 and the setting of the slope. When it needs to be taken out, the crushed granite inside can be discharged through the discharge port 14. The slope can make the discharge more convenient and reduce internal residues.

[0045] When using, First, granite is fed through the feed port. When the granite enters the equipment, it will first enter the coarse material chute. The smaller granite can be directly screened out through the feed screen 12 and directly enter the crushing through the fine material chute. The larger fragments will continue to slide down through the coarse material chute and be pierced by the piercing mechanism 4 before being crushed.

[0046] Secondly, by starting the driving motor 41, the gear rotating disk 42 is rotated. When the gear rotating disk 42 rotates, the driving gear 43 and the driven gear 44 are rotated. When the driven gear 44 is meshed with the gear rotating disk 42, it will rotate clockwise. When the driven gear 44 is meshed with the driving gear 43, it will rotate counterclockwise. The driven gear 44 is repeatedly rotated through the tooth interval of the gear rotating disk 42 and the half gear of the driving gear 43. When the driven gear 44 rotates, it will drive the bidirectional screw rod 45 to rotate. The grooves can make the two groups of traction plates 46 reciprocate, and the traction plates 46 can push or pull the puncture plates 47 to reciprocate while the traction plates 46 reciprocate. When the puncture plates 47 are clamped, the granite is punctured, which can destroy the overall structural stability of the granite. When the granite is subsequently crushed, it will contact the impact hammer 25 and be impacted by the impact hammer 25, and it will be directly broken into multiple small pieces. At this time, crushing can reduce the wear of the impact hammer 25, and at the same time prevent larger granite from getting stuck in the equipment, thereby causing damage to the equipment.

[0047] Then, by starting the crushing motor 21, the transmission belt 22 is driven to transmit power to the rotating shaft 23. When the rotating shaft 23 rotates, the centrifugal wheel 33 will be thrown out and engaged with the hammer frame 24 due to the influence of centrifugal force. Since there are two connecting blocks 31 without the traction of the compression spring 32, the engaging point of the centrifugal wheel 33 and the hammer frame 24 will always be the two sets of connecting blocks 31. When the centrifugal wheel 33 is engaged with the hammer frame 24, the hammer frame 24 will rotate synchronously. The force area can be increased by setting the contact teeth and the centrifugal teeth. When the contact teeth and the centrifugal teeth are in contact, the contact area will be increased. When vibrated, they will not separate directly, avoiding power loss caused by separation due to vibration. When the hammer frame 24 rotates, the impact hammer 25 can be used for stone crushing. In order to avoid the impact hammer 25 from breaking due to uneven force due to the small contact area with the hammer frame 24, when the hammer frame 24 rotates When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact hammer 25. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact block 30 is moved to the inside of the impact block 29. When the impact hammer 25 is in the state of being moved, the impact

[0048] Afterwards, through the setting of the crushing chute, the larger fragments after crushing can be hooked up by the arc surface of the impact hammer 25 and move upward along the crushing chute. When they reach the top of the hammer frame 24, they will lose the supporting force and fly out in the axial direction of the hammer frame 24 under the influence of centrifugal force. After flying out, they will collide with the impact plate 17 again, making them smaller fragments, and then fall through the screening of the crushing screen 13.

[0049] Finally, the crushed granite can be discharged through the setting of the discharge chamber 15 and the setting of the slope. When it needs to be taken out, the crushed granite inside can be discharged through the discharge port 14. The slope can make the discharge more convenient and reduce the internal residue.

[0050] During maintenance, First, when the whole equipment needs to be shut down, the compression spring 32 will be compressed when the centrifugal wheel 33 is engaged with the hammer frame 24. When the rotation stops, the compression spring 32 will rebound and push the connecting block 31 to make the centrifugal wheel 33 return to its original position. At this time, the centrifugal wheel 33 is not engaged with the hammer frame 24, so that each group of hammer frames 24 can rotate freely. The impact hammers 25 can be arranged by freely rotating the hammer frame 24. When crushing smaller granite, the impact hammers 25 can be dispersedly arranged. Through the staggered impact hammers 25, the granite can be repeatedly struck by different impact hammers 25 during crushing, which increases efficiency and makes wear more uniform, increases the service life of the impact hammers 25, and reduces the replacement frequency. When crushing larger granite, the impact hammers 25 can be arranged in a straight line to achieve the best stability, avoid excessive dispersion and poor crushing effect, and even increase the wear of the impact hammers 25. Secondly, the counter-attack hammer 25 can be checked by rotating the hammer frame 24 counterclockwise. Since the weight of the counter-attack hammer 25 after wear is lower than that of the relatively intact counter-attack hammer 25, the heavier counter-attack hammer 25 will be rotated to the bottom of the hammer frame 24 by gravity. Therefore, the severely worn counter-attack hammer 25 will usually be at the top of the hammer frame 24. When a severely worn counter-attack hammer 25 is found, the hammer frame 24 can be rotated counterclockwise so that the buffer block 30 is subjected to gravity and enters the interior of the buffer block 29, and the counter-attack hammer 25 is directly pulled out. Since redundant space is provided in the disassembly groove, when the counter-attack hammer 25 is pulled upward, the self-locking block 28 will move upward in the redundant space, and there will be extra space at the bottom of the disassembly groove. The pressure block 26 can be made to move downward autonomously due to gravity. When the pressure block 26 moves downward, it will pull the self-locking block 28 to move inward, and when the self-locking block 28 contacts the top of the disassembly groove, it will be pushed downward by the disassembly groove. Since the top of the self-locking block 28 is inclined, when the self-locking block 28 is pushed, it will further shrink into the inside of the hammer frame 24. When the self-locking block 28 is completely retracted into the inside of the hammer frame 24, the counter-attack hammer 25 can be taken out. Since the length of the pressure block 26 is the same as that of the self-locking block 28, after the counter-attack hammer 25 is taken out, the pressure block 26 can be pushed into the inside of the traction groove. At this time, the pressure block 26, the traction connecting rod 27 and the self-locking block 28 can be taken out and installed into the inside of the new counter-attack hammer 25. Finally, when the counter-attack hammer 25 is installed, since the gravity of the counter-attack hammer 25 is heavier than the pressure block 26, the traction link 27 and the self-locking block 28, when the counter-attack hammer 25 enters the disassembly groove, the pressure block 26 will contact the bottom of the disassembly groove and be forced to move upward. When the pressure block 26 moves upward, the traction link 27 will pull the self-locking block 28 to move outward. When the self-locking block 28 enters the interior of the hammer frame 24, it will engage with the hammer frame 24 through the plane on the top of the self-locking block 28, and the counter-attack hammer 25 can be fixed at this time; when the counter-attack hammer 25 is at the bottom of the hammer frame 24, the pressure block 26 will enter the interior of the rectangular slide groove due to gravity. When the pressure block 26 enters, the self-locking block 28 will completely enter the interior of the disassembly groove and make it completely fit with both sides of the disassembly groove, thereby preventing the counter-attack hammer 25 from being affected by gravity when it is at the bottom of the hammer frame 24. The impact of the self-locking block 28 is such that the self-locking block 28 falls off; since there is redundant space for the movement of the self-locking block 28, the granite will continue to hit the impact hammer 25 during the crushing operation, which will generate a downward pressure on the impact hammer 25. At the same time, since there is redundant space at the bottom of the pressure plate for taking out, when the pressing block 26 is under pressure, it can be further inserted into the interior of the impact hammer 25, and the self-locking block 28 is pulled by the traction link 27 to make the engagement between the self-locking block 28 and the impact hammer 25 more secure; when the impact hammer 25 is crushed, the reaction force of the broken pieces will be received, which will cause the self-locking block 28 to generate inertia. When one group of the self-locking blocks 28 is moved by gravity and inertia, it will pull the traction link 27 and move the pressing block 26 upward. When the pressing block 26 moves upward, it will also move the other group of self-locking blocks 28 outward, thereby increasing stability.
