Description

Technical Field

[0001] This invention relates to the field of putty powder production and pulverization technology, and in particular to an impact pulverizing device based on putty powder production. Background Technology

[0002] Marble, as a natural stone widely used in building decoration materials, generates a large amount of waste during its processing, including unused marble blocks, stone chips, and powder. These waste materials can be used to produce building materials such as putty powder. In existing technologies, jaw crushers are usually used to impact and crush marble blocks to process marble into fine powder, which can be used as raw materials for the preparation of putty powder.

[0003] The existing publication number CN117505020A discloses an impact crushing device and process for producing putty powder main raw materials, including an inner box, which is a rectangular box structure with openings at both the top and bottom. The inner box is equipped with a crushing cylinder with an internal cavity, and the upper end face of the crushing cylinder is provided with a discharge port. A crushing mechanism for impact crushing the raw materials is provided between the crushing cylinder and the inner box, and a collection mechanism for collecting finished products that meet the required size is provided at the lower end of the crushing cylinder.

[0004] While the aforementioned technical solutions enable the crushing drum to drive the putty powder raw material in rapid up-and-down and left-and-right reciprocating motions, thus improving the impact crushing efficiency, in existing technologies, when using a jaw crusher to crush marble blocks, due to the physical properties of marble, some larger or irregularly shaped marble blocks are prone to getting stuck between the moving and fixed jaw plates during crushing. Once stuck, the moving jaw plate may suffer severe impact and compression under continuous working pressure, affecting its range of motion and reducing the overall working efficiency of the crusher. Currently, to address the stuck problem, operators typically need to manually handle the stuck stones. This process is not only tedious and time-consuming, but also carries the risk that the stuck stones may suddenly loosen or burst out during manual handling, posing a threat to the safety of the workers. Therefore, a new type of impact crushing equipment based on putty powder production is needed to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide an impact crushing device based on putty powder production, in order to solve the problem mentioned in the background art that when using a jaw crusher to crush marble blocks, large or irregularly shaped marble blocks are easily stuck between the moving jaw plate and the fixed jaw plate, causing blockage.

[0006] The present invention provides an impact crushing device based on putty powder production, which adopts the following technical solution:

[0007] An impact crushing device based on putty powder production includes a crusher. The crusher includes a main frame, a fixed jaw plate fixedly installed on the main frame, an outer frame set on the main frame, and a movable jaw plate movably installed on the outer frame. A crushing chamber is formed between the fixed jaw plate and the movable jaw plate. The main frame is also provided with a drive assembly and a controller. The drive assembly acts on the movable jaw plate to drive the movable jaw plate to reciprocate and move away from and towards the fixed jaw plate. Hammering mechanisms are symmetrically arranged at the front and rear positions of the main frame.

[0008] The hammering mechanism includes a support plate symmetrically fixed at the front and rear positions of the main frame, a rotating arm rotatably mounted on the support plate, a spline rod rotatably connected to the end of the rotating arm, a connecting rod sleeved on the spline rod via a spline, an impact column rotatably connected to the end of the connecting rod, a hammer head fixed to the end of the impact column, and a sleeve movably mounted on the outer frame via a reciprocating mechanism. The sleeve has a slot for the impact column to move up and down. A first counterweight is fixed on the impact column, and the first counterweight is located in the slot. A spring is also wound around the impact column.

[0009] The support plate is equipped with a control mechanism, which is used to control the rotation of the rotating arm, so that the impact column and hammer head can move up and down reciprocally.

[0010] Furthermore, the control mechanism includes a driven shaft rotatably mounted on the support plate, a sleeve fixed on the driven shaft, a protrusion fixed on the outer edge of the sleeve, and a protrusion fixed on the rotating arm. The rotating arm is rotatably connected to the support plate via a bearing and is movably sleeved outside the driven shaft.

[0011] When the driven shaft rotates, the protrusion rotates together with the sleeve block around the driven shaft and abuts against the protrusion. When the protrusion rotates to the highest point, the protrusion disengages from the protrusion, causing the impact column and hammer to move downward.

[0012] Furthermore, the reciprocating mechanism includes a base fixed to the top of the outer frame, a double-ended screw rotatably mounted on the base, threaded sleeves threaded onto both ends of the double-ended screw, a connecting plate fixed to the threaded sleeves, and a collar fixedly connected to the connecting plate, wherein the collar is fixedly mounted on the sleeve.

[0013] A slider is also fixed on the screw sleeve, and a groove for limiting the movement of the slider is provided on the base.

[0014] Furthermore, the impact column is provided with a striking mechanism, which includes a fixed ring fixed on the impact column, a connecting frame symmetrically fixed at the front and rear positions of the fixed ring, a shaft rotatably mounted on the connecting frame, swing arms fixed at both ends of the shaft, and shovel heads fixed at the ends of the swing arms. The positions of the front and rear sets of shovel heads are offset from each other.

[0015] Furthermore, a second counterweight is also fixed to the shovel head.

[0016] Furthermore, the striking mechanism also includes a gear fixed on the shaft and a toothed plate fixed to the bottom end of the sleeve. When the impact column moves, the gear meshes with the toothed plate.

[0017] The shaft is also equipped with a torsion spring, the two ends of which abut against the end faces of the connecting frame and the gear, respectively.

[0018] Furthermore, a baffle is fixed to the bottom end of the sleeve, and the baffle has an arc-shaped design on both the top and bottom sides near the swing arm.

[0019] Furthermore, the control mechanism also includes a first motor fixedly mounted on the main frame, the output end of the first motor being fixed with a drive shaft, and a transmission component being provided between the drive shaft and the driven shaft;

[0020] A support frame is fixedly installed on the main frame, and the drive shaft is rotatably connected to the support frame through bearings.

[0021] Furthermore, the reciprocating mechanism also includes a second motor fixed on the outer frame. The output shaft of the second motor is fixed with a driving bevel gear, and the double-ended screw is fixed with a driven bevel gear. The driven bevel gear meshes with the driving bevel gear.

[0022] Furthermore, the inner walls at both ends of the slot are provided with multiple sets of circular grooves, and ball bearings are rotatably arranged in the circular grooves, with the ball bearings contacting the impact column.

[0023] The beneficial effects of this invention are:

[0024] 1. Equipped with a hammering mechanism and a control mechanism, the driven shaft is rotated by a first motor, which in turn controls the rotating arm to raise the spline rod, connecting rod, impact column, and hammer head. When the convex block rotates to its highest position under the elastic force of the spring, the hammer head can quickly move downward to hammer the marble block stuck between the fixed jaw plate and the moving jaw plate. The impact force applied by the hammer head can further break the marble block, loosening the stuck marble block. This can relieve the blockage caused by the large size or irregular shape of the marble block. Furthermore, the reciprocating hammering of the hammer head can quickly handle the blockage, thereby reducing the time required for manual handling, lowering operational risks, and enhancing the safety of the work site.

[0025] 2. By incorporating a reciprocating mechanism, the impact column can be stored on the side of the crushing chamber when not in use, thus saving space and ensuring the normal operation of the crusher. In the event of a blockage, the connecting rod, impact column, hammer, and sleeve can be quickly moved to the top of the crushing chamber to address the blockage promptly, thereby avoiding downtime and production delays and improving overall production efficiency.

[0026] 3. By incorporating a striking mechanism, when the impact column drives the hammer head downwards, the gears, toothed plates, and torsion springs control the shovel head to swing outwards. The swinging of the shovel head simultaneously achieves the dual effects of hammering and pushing. Furthermore, while participating in the crushing process, the shovel head can also push loose stones outwards, further reducing the occurrence of blockages. Through the linkage between the hammer head and the shovel head, gravity and the potential energy generated by motion can be used to work together, improving the crushing effect on marble blocks stuck between the fixed jaw plate and the moving jaw plate.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Reference Figures 1-2An impact crushing device based on putty powder production includes a crusher 1. The crusher 1 includes a main frame 11, a fixed jaw plate 12 fixedly mounted on the main frame 11, an outer frame 13 mounted on the main frame 11, and a movable jaw plate 14 movably mounted on the outer frame 13. A crushing chamber is formed between the fixed jaw plate 12 and the movable jaw plate 14. The main frame 11 is also provided with a drive assembly 2 and a controller 3. The drive assembly 2 acts on the movable jaw plate 14, driving the movable jaw plate 14 to reciprocate away from and towards the fixed jaw plate 12. The drive assembly 2 includes a motor, a belt assembly, a main pulley assembly, a connecting rod, and an eccentric mechanism. When the motor starts, it drives the belt assembly and the main pulley assembly to rotate, which in turn causes the eccentric shaft to rotate. Due to the eccentric design of the eccentric shaft, the rotation of the shaft will produce an alternating up and down motion. The rotation of the eccentric shaft is transmitted to the moving jaw plate 14 through the connecting rod. As the moving jaw plate 14 moves up and down, the marble block is clamped and crushed between the fixed jaw plate 12 and the moving jaw plate 14. The bottom of the crushing chamber is the discharge port, which is used to discharge the small particles of crushed material. Since the specific connection and specific composition of the drive assembly 2 are existing technologies well known in the art, they will not be described in detail here.

[0043] Reference Figures 3-7 Hammering mechanisms 4 are symmetrically arranged at the front and rear positions of the main frame 11;

[0044] Specifically, the hammering mechanism 4 includes a support plate 41 symmetrically fixed at the front and rear positions of the main frame 11, a rotating arm 42 rotatably mounted on the support plate 41, a spline rod 43 rotatably connected to the end of the rotating arm 42 via a bearing, a connecting rod 44 sleeved on the spline rod 43 via a spline, an impact column 45 rotatably connected to the end of the connecting rod 44 via a rotating shaft, a hammer head 46 fixed to the end of the impact column 45, and a sleeve 47 movably mounted on the outer frame 13 via a reciprocating mechanism 6. The sleeve 47 has a slot 471 for the impact column 45 to move up and down. The impact column 45 passes through the slot 471. A first counterweight 48 is fixed on the impact column 45. The first counterweight 48 is located in the slot 471 and can move up and down in the slot 471. A spring 49 is also wound around the impact column 45. The two ends of the spring 49 are respectively fixed to the inner top wall of the slot 471 and the top of the first counterweight 48.

[0045] Among them, reference Figure 6 The inner walls at both ends of the slot 471 are circumferentially formed with multiple sets of circular grooves 472. Roller balls 473 are rotatably installed in the circular grooves 472. The roller balls 473 contact the impact column 45. When the impact column 45 moves up and down in the slot 471, the rotation of the circular grooves 472 can reduce the friction generated during the up and down movement of the impact column 45, thereby improving the smoothness of the up and down movement of the impact column 45.

[0046] Reference Figure 5 , Figures 7-8 The support plate 41 is equipped with a control mechanism 5, which is used to control the rotation of the rotating arm 42, so that the impact column 45 and the hammer head 46 can move up and down reciprocally.

[0047] Specifically, the control mechanism 5 includes a driven shaft 51 rotatably mounted on the support plate 41, a sleeve block 52 fixed on the driven shaft 51, a protrusion 53 fixed on the outer edge of the sleeve block 52, and a protrusion 54 fixed on the rotating arm 42. The rotating arm 42 is rotatably connected to the support plate 41 through a bearing and is movably sleeved outside the driven shaft 51.

[0048] When the driven shaft 51 rotates, the protrusion 53 rotates together with the sleeve block 52 around the driven shaft 51. During the rotation, the protrusion 53 abuts against the protrusion 54, and at the same time controls the rotation of the rotating arm 42, causing the spline rod 43 to drive the connecting rod 44, the impact column 45, the hammer head 46, and the first counterweight block 48 to move upward. At the same time, the spring 49 is compressed. When the protrusion 53 rotates to the highest position, the protrusion 54 disengages from the protrusion 53 under the elastic force of the spring 49, and then controls the hammer head 46 to move downward quickly to hammer the marble block. Through the impact force applied by the hammer head 46, the marble block is further broken, and the stuck marble block is loosened. This can relieve the blockage caused by insufficient gap between the blocks. Furthermore, by quickly handling the blockage, the time for manual handling is reduced, the operational risk is reduced, and the safety of the work site is enhanced.

[0049] The control mechanism 5 also includes a first motor 55 fixedly mounted on the main frame 11. The first motor 55 is connected to the controller 3 via telecommunications. The output end of the first motor 55 is fixedly equipped with a drive shaft 56. A transmission component 57 is provided between the drive shaft 56 and the driven shaft 51. A support frame 58 is fixedly mounted on the main frame 11. The drive shaft 56 is rotatably connected to the support frame 58 via a bearing.

[0050] Specifically, transmission components 57 are provided between the front and rear ends of the drive shaft 56 and the two sets of driven shafts 51, respectively. The transmission components 57 include pulleys and a conveyor belt. The pulleys are fixed at the front and rear ends of the drive shaft 56 and the ends of the two sets of driven shafts 51 away from the support plate 41, respectively. The conveyor belt is taut and wound between the corresponding two sets of pulleys. When the first motor 55 is started, it can control the drive shaft 56 to rotate. With the transmission action of the transmission components 57, it can control the two sets of driven shafts 51 to rotate simultaneously, thereby causing the impact column 45 and the hammer head 46 to move up and down to achieve the effect of hammering the marble block.

[0051] Reference Figures 8-10The reciprocating mechanism 6 includes a base 61 fixed to the top of the outer frame 13, a double-ended screw 62 rotatably mounted on the base 61, threaded sleeves 63 threaded to both ends of the double-ended screw 62, a connecting plate 64 fixed to the threaded sleeves 63, and a collar 65 fixedly connected to the connecting plate 64. The collar 65 is fixedly mounted on the sleeve 47. The threads at both ends of the double-ended screw 62 are designed to be opposite. A slider 631 is also fixed on the threaded sleeve 63. The base 61 has a sliding groove 632 for limiting the movement of the slider 631. When the double-ended screw 62 rotates, the threaded sleeves 63 threaded to both ends of the double-ended screw 62 can move closer or further apart under the limiting cooperation of the slider 631 and the sliding groove 632.

[0052] Specifically, the reciprocating mechanism 6 also includes a second motor 66 fixed on the outer frame 13. The second motor 66 is connected to the controller 3 via telecommunications. The output shaft of the second motor 66 is fixed with an active bevel gear 67, and the double-ended screw 62 is fixed with a driven bevel gear 68. The driven bevel gear 68 meshes with the active bevel gear 67. After the second motor 66 is started, it can control the active bevel gear 67, the driven bevel gear 68 and the double-ended screw 62 to rotate, so that the screw sleeves 63 located at both ends of the double-ended screw 62 can simultaneously drive the front and rear sets of sleeves 47 to move closer or further away from each other. When the sleeves 47 move closer or further away from each other, the connecting rod 44 can move on the surface of the splined rod 43 via splines.

[0053] By incorporating a reciprocating mechanism 6, the impact column 45 can be stored on the side of the crushing chamber when not in use, thus saving space and ensuring the normal operation of the crusher 1. In the event of a blockage, the connecting rod 44, impact column 45, hammer 46, and sleeve 47 can be quickly moved to the top of the crushing chamber to address the problem promptly, thereby avoiding downtime and production delays and improving overall production efficiency.

[0054] During use, by starting the second motor 66, the second motor 66 controls the rotation of the active bevel gear 67, which in turn drives the driven bevel gear 68 and the double-ended screw 62 to rotate. Through the limiting cooperation of the slider 631 and the slide groove 632, the threaded sleeves 63 at both ends of the double-ended screw 62 can be connected by the connecting plate 64 and the collar 65, which drives the two sets of sleeves 47 to move closer to each other. At the same time, the connecting rod 44 moves on the surface of the spline rod 43 through the spline. When the two sets of sleeves 47 move to the top of the crushing chamber, the second motor 66 is turned off and the first motor 55 is started.

[0055] By starting the first motor 55, the drive shaft 56 is rotated. At this time, under the transmission action of the transmission component 57, the two driven shafts 51 rotate synchronously. When the driven shaft 51 rotates, the sleeve block 52 and the protrusion 53 are controlled to rotate simultaneously. As the protrusion 53 follows the sleeve block 52 and rotates around the driven shaft 51, during the rotation, the protrusion 53 contacts and abuts against the protrusion 54, thereby simultaneously controlling the rotating arm 42 to rotate. When the rotating arm 42 rotates... The key rod 43 drives the connecting rod 44 to rotate, and at the same time drives the impact column 45 to move upward in the slot 471. As the impact column 45 moves upward, the hammer head 46 and the first counterweight block 48 move upward, and control the spring 49 to compress. When the protrusion 53 rotates to the highest position, the protrusion 54 disengages from the protrusion 53 under the elastic force of the spring 49. At this time, through the cooperation of the rotating arm 42, the spline rod 43 and the connecting rod 44, the impact column 45 controls the hammer head 46 to move downward quickly to hammer the marble block.

[0056] It is worth noting that sensors can also be installed on the crusher 1. The sensors are connected to the controller 3 via telecommunications. The first motor 55 and the second motor 66 are both connected to the controller 3 via telecommunications.

[0057] The sensor can be a load sensor installed on the fixed jaw plate 12 or the movable jaw plate 14. When the sensor is a load sensor, it can monitor the load changes of the fixed jaw plate 12 and the movable jaw plate 14 in real time. When the marble block is compressed and crushed, the force generated will be measured by the load sensor. The load sensor converts the mechanical load into an electrical signal. The load sensor transmits the detected load signal to the controller 3. The controller 3 will analyze the load according to the preset threshold. When the load exceeds the set threshold, the controller 3 will react and first control the second motor 66 to run. When the second motor 66 runs and controls the sleeve 47 to drive the connecting rod 44, the impact column 45 and the hammer 46 to move up to the top of the crushing chamber, the controller 3 will send a power-off signal to stop the second motor 66. Then the controller 3 will control the first motor 55 to run. When the first motor 55 runs, it will control the hammer 46 to move up and down to hammer the marble block.

[0058] The sensor can also be a displacement sensor installed on the moving jaw plate 14. When the sensor is a displacement sensor, it will sense the relative displacement of the moving jaw plate 14 during the working process and convert it into an electrical signal. The displacement sensor will transmit the measured displacement signal to the controller 3. The controller 3 will determine the working state of the moving jaw plate 14 based on the received displacement signal. When the displacement signal is abnormal, the controller 3 will react and first control the second motor 66 to run. When the second motor 66 runs and controls the sleeve 47 to drive the connecting rod 44, the impact column 45 and the hammer 46 to move as a whole to the top of the crushing chamber, the controller 3 will send a power-off signal to stop the operation of the second motor 66. Then the controller 3 will control the first motor 55 to run. When the first motor 55 runs, it will control the hammer 46 to move up and down to hammer the marble block.

[0059] Through intelligent control between sensors, controller 3, first motor 55 and second motor 66, the crushing process can be effectively optimized and the overall production efficiency improved by utilizing real-time monitoring and control of sensors.

[0060] Furthermore, refer to Figures 11-12 The impact column 45 is equipped with a striking mechanism 7;

[0061] The striking mechanism 7 includes a fixed ring 71 fixed on the impact column 45, a connecting frame 72 symmetrically fixed at the front and rear positions of the fixed ring 71, a shaft 73 rotatably mounted on the connecting frame 72 via bearings, a swing arm 74 fixed at both ends of the shaft 73, and a shovel head 75 fixed at the end of the swing arm 74. The positions of the front and rear shovel heads 75 are offset from each other. When the swing arm 74 drives the shovel head 75 to swing back and forth, the positions of the front and rear shovel heads 75 are offset from each other, which can prevent collisions between the front and rear shovel heads 75.

[0062] It should be noted that the retaining ring 71 is fixed to the part of the shovel head 75 located below the sleeve 47. When the shovel head 75 moves up and down in the slot 471, the retaining ring 71 is always below the sleeve 47.

[0063] Specifically, the striking mechanism 7 also includes a gear 77 fixed on the shaft 73 and a toothed plate 78 fixed to the bottom of the sleeve 47. When the impact column 45 moves, the gear 77 meshes with the toothed plate 78, which is located inside the gear 77. The shaft 73 is also equipped with a torsion spring 79, the two ends of which abut against the end faces of the connecting frame 72 and the gear 77, respectively. When the impact column 45 drives the hammer head 46 to move downward, it can simultaneously control the fixed ring 71, the connecting frame 72, the shaft 73, the swing arm 74, and the shovel head 75 to move downward. When the gear 77 meshes with the toothed plate 78, the gear 77 controls the shaft 73 and the swing arm 74 to rotate. At this time, the swing arm 74, located in front of and behind the fixed ring 71, drives the shovel head 75 to swing inward. Due to the positions of the front and rear sets of shovel heads 75... The shovels are offset from each other, so no collision occurs when the shovel head 75 swings inward. At the same time, the torsion spring 79 stores energy. When the gear 77 and the toothed plate 78 disengage, the torsion spring 79 releases its stored energy, which controls the swing arm 74 to drive the shovel head 75 to swing outward. The swing of the shovel head 75 can achieve the dual effects of hammering and pushing at the same time. While participating in crushing, the shovel head 75 can push loose stones outward, further reducing the occurrence of jamming. In addition, the swing of the shovel head 75 can increase the impact on irregularly shaped marble blocks. Through the linkage effect of the hammer head 46 and the shovel head 75, the potential energy generated by gravity and motion can be used to work together to improve the crushing effect on marble blocks stuck between the fixed jaw plate 12 and the moving jaw plate 14, thereby speeding up the removal speed of marble blocks.

[0064] The shovel head 75 is also fixed with a second counterweight 76, which is sleeved and fixed on the swing arm 74. By adding the second counterweight 76 to the shovel head 75, the inertia of the swing of the shovel head 75 can be increased, thereby enhancing the pushing force of the shovel head 75 on the marble block and improving its crushing effect.

[0065] The bottom end of the sleeve 47 is also fixed with a baffle 741 for limiting the swing arm 74. The baffle 741 has an arc-shaped design on both the top and bottom sides near the swing arm 74. With the baffle 741, when the impact column 45 controls the hammer head 46, the fixing ring 71, the connecting frame 72, the shaft 73, the swing arm 74 and the shovel head 75 to move upward as a whole, the gear 77 will still mesh with the toothed plate 78 during the upward movement of the shovel head 75, so that the spring 49 will store force again. When the gear 77 disengages from the toothed plate 78, the swing arm 74 can contact the baffle 741. Under the action of the baffle 741, the swing of the swing arm 74 and the shovel head 75 can be limited.

[0066] During use, since the retaining ring 71 is fixed to the part of the shovel head 75 located below the sleeve 47, when the impact column 45 controls the hammer head 46 to move downward, the retaining ring 71, connecting frame 72, shaft 73, swing arm 74, shovel head 75, second counterweight 76, gear 77, and torsion spring 79 simultaneously move downward with the impact column 45. When the gear 77 moves to the toothed plate 78, the gear 77 meshes with the toothed plate 78, thereby causing the gear 77 to drive the shaft 73, swing arm 74, and shovel head 75. The second counterweight 76 rotates inward, while the torsion spring 79 stores energy. As the shovel head 75 continues to move downward, the torsion spring 79 releases its stored energy after the gear 77 and toothed plate 78 disengage. At this time, the swing arm 74 is controlled to drive the shovel head 75 to swing outward, and the second counterweight 76 increases the inertia of the shovel head 75, allowing the shovel head 75 to swing back and forth to strike irregular marble blocks. At the same time, it can also push away the broken stones that fall on the marble blocks, further reducing the occurrence of blockage.
