Description

Technical Field

[0001] The invention relates to the technical field of putty powder production and pulverization, in particular to an impact pulverization device based on putty powder production. Background Art

[0002] Marble is a natural stone widely used in building decoration materials. During its processing, a large amount of waste is generated, including unused marble blocks, stone chips and powder. These waste materials can be used to produce building materials such as putty powder. In the prior art, a jaw crusher is usually used to impact and crush marble blocks to process the marble into fine powder as a raw material for preparing putty powder.

[0003] The existing publication number CN117505020A discloses an impact crushing device and process for producing the main raw material of putty powder, which includes a built-in box. The built-in box is a rectangular box structure with openings on the top and bottom. A crushing cylinder with a hollow interior is arranged in the built-in box, and a discharge port is opened on the upper end surface of the crushing cylinder; a crushing mechanism for impact crushing the raw materials is jointly arranged between the crushing cylinder and the built-in box, and a collecting mechanism for collecting finished products meeting the required size is arranged at the lower end of the crushing cylinder.

[0004] Although the above technical scheme can enable the crushing drum to drive the putty powder raw material to move back and forth rapidly up and down and left and right, and has the advantage of improving the impact crushing efficiency of the raw material, in the prior art, when using a jaw crusher to crush marble blocks, due to the physical properties of marble, some large or irregularly shaped marble blocks are easily stuck between the movable jaw plate and the fixed jaw plate during crushing. After the jam occurs, the movable jaw plate may be severely impacted and squeezed under continuous working pressure, resulting in its range of motion being affected, resulting in a decrease in the overall working efficiency of the crusher. At present, in order to deal with the jam problem, operators usually need to manually handle the stuck stones. This process is not only cumbersome and time-consuming, but also during the manual handling process, the stuck stones may suddenly loosen or burst out, thereby posing a threat to the safety of the staff.

[0026] 3. By setting up a knocking mechanism, when the impact column drives the hammer head to move downward, the shovel head can be controlled to swing outward under the action of gears, tooth plates and torsion springs.

DETAILED DESCRIPTION

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] Reference Figure 1-Figure 2An impact crushing device based on putty powder production includes a crusher 1, which includes a main frame 11, a fixed jaw plate 12 fixedly installed on the main frame 11, an outer frame 13 arranged on the main frame 11, and a movable jaw plate 14 movably installed on the outer frame 13. A crushing chamber is formed between the fixed jaw plate 12 and the movable jaw plate 14. A driving assembly 2 and a controller 3 are also provided on the main frame 11. The driving assembly 2 acts on the movable jaw plate 14 to drive the movable jaw plate 14 to reciprocate away from and close to the fixed jaw plate 12. The driving assembly 2 includes a motor, a belt group, a main pulley group, a connecting rod, and an eccentric Shaft, when the motor is started, the motor drives the belt group and the main pulley group to rotate, thereby causing 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 movement, and the rotation of the eccentric shaft transmits this movement to the movable jaw plate 14 through the connecting rod. As the movable jaw plate 14 moves up and down, the marble block is clamped and crushed between the fixed jaw plate 12 and the movable jaw plate 14, and the bottom of the crushing chamber is a discharge port for the crushed small particle material to flow out. Since the specific connection and specific composition of the drive assembly 2 are prior art well known in the art, they will not be described in detail here.

[0043] Reference Figure 3-Figure 7 , hammering mechanisms 4 are symmetrically provided 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 arranged on the support plate 41, a spline rod 43 rotatably connected to the end of the rotating arm 42 through a bearing, a connecting rod 44 sleeved on the spline rod 43 through a spline, an impact column 45 rotatably connected to the end of the connecting rod 44 through a rotating shaft, a hammer head 46 fixed to the end of the impact column 45, and a sleeve 47 movably arranged on the outer frame 13 through a reciprocating mechanism 6, a slot 471 for the impact column 45 to move up and down is opened in the sleeve 47, the impact column 45 passes through the slot 471, a first counterweight block 48 is fixed on the impact column 45, the first counterweight block 48 is located in the slot 471, and can move up and down in the slot 471, and a spring 49 is also wound around the impact column 45, and 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 block 48.

[0045] Among them, refer to Figure 6 The inner walls at the upper and lower ends of the groove 471 are circumferentially provided with multiple groups of circular grooves 472, and balls 473 are rotatably arranged in the circular grooves 472. The balls 473 are in contact with the impact column 45. When the impact column 45 moves up and down in the groove 471, the friction generated during the up and down movement of the impact column 45 can be reduced through the rotation of the circular grooves 472, thereby improving the smoothness of the up and down movement of the impact column 45.

[0046] Reference Figure 5 , Figure 7-Figure 8 A control mechanism 5 is provided on the support plate 41, and the control mechanism 5 is used to control the rotation of the rotating arm 42 so that the impact column 45 and the hammer head 46 can reciprocate up and down;

[0047] Specifically, the control mechanism 5 includes a driven shaft 51 rotatably set 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 the rotating arm 42 is movably sleeved outside the driven shaft 51.

[0048] When the driven shaft 51 rotates, the protrusion 53 rotates 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, so that the spline rod 43 drives the connecting rod 44, the impact column 45, the hammer head 46 and the first counterweight block 48 to move upward, and at the same time controls the compression of the spring 49. When the protrusion 53 rotates to the highest point, the protrusion 54 is disengaged 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. The impact force exerted by the hammer head 46 further breaks the marble block and loosens the stuck marble block, thereby eliminating the jamming caused by insufficient clearance between the blocks. In addition, by quickly handling the jamming situation, the time for manual handling is reduced, while reducing the operating risk and enhancing the safety of the work site.

[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 telecommunication. A driving shaft 56 is fixedly mounted on the output end of the first motor 55. A transmission component 57 is provided between the driving shaft 56 and the driven shaft 51. A support frame 58 is fixedly mounted on the main frame 11. The driving shaft 56 is rotatably connected to the support frame 58 via a bearing.

[0050] Specifically, transmission components 57 are respectively provided between the front and rear ends of the driving shaft 56 and the two groups of driven shafts 51. The transmission component 57 includes a pulley and a conveyor belt. The pulleys are respectively fixed to the front and rear ends of the driving shaft 56 and the ends of the two groups of driven shafts 51 away from the support plate 41, and the conveyor belt is tightly wound between the corresponding two groups of pulleys. When the first motor 55 is started, the driving shaft 56 can be controlled to rotate. With the transmission action of the transmission component 57, the two groups of driven shafts 51 can be controlled to rotate at the same time, so that the impact column 45 and the hammer head 46 can move up and down reciprocatingly to achieve the effect of hammering the marble block.

[0051] Reference Figure 8-Figure 10The reciprocating mechanism 6 includes a base 61 fixed to the top of the outer frame 13, a double-headed screw 62 rotatably arranged on the base 61, a screw sleeve 63 threadedly sleeved on both ends of the double-headed screw 62, a connecting plate 64 fixed on the screw sleeve 63, and a collar 65 fixedly connected to the connecting plate 64, wherein the collar 65 is fixedly sleeved on the sleeve 47, wherein the threads at both ends of the double-headed screw 62 are of opposite design, a slider 631 is also fixed on the screw sleeve 63, and a sliding groove 632 for limiting movement of the slider 631 is provided on the base 61. When the double-headed screw 62 rotates, the screw sleeve 63 threadedly sleeved on both ends of the double-headed screw 62 can approach or move away from each other 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 telecommunication. An active bevel gear 67 is fixed to the output end shaft of the second motor 66. A driven bevel gear 68 is fixed to the double-headed screw 62. The driven bevel gear 68 is meshed with the active bevel gear 67. After starting the second motor 66, the active bevel gear 67, the driven bevel gear 68 and the double-headed screw 62 can be controlled to rotate, so that the screw sleeves 63 located at both ends of the double-headed screw 62 can simultaneously drive the front and rear sets of sleeves 47 to approach or move away from each other, and when the sleeves 47 approach or move away from each other, the connecting rod 44 can move through the spline on the surface of the spline rod 43.

[0053] By providing a reciprocating mechanism 6, the impact column 45 can be stored to the side of the crushing chamber when not in use, which helps to save space and ensure the normal operation of the crusher 1. When a blockage occurs, the connecting rod 44, the impact column 45, the hammer head 46 and the sleeve 47 can be quickly moved to the top of the crushing chamber to deal with the problem in time, thereby avoiding downtime and production delays, thereby improving overall production efficiency.

[0054] During use, by starting the second motor 66, the second motor 66 controls the active bevel gear 67 to rotate, so that the active bevel gear 67 drives the driven bevel gear 68 and the double-headed screw 62 to rotate, and through the limited cooperation of the slider 631 and the slide groove 632, the screw sleeve 63 threadedly sleeved on both ends of the double-headed screw 62 can drive the two sets of sleeves 47 to approach each other through the connection of the connecting plate 64 and the collar 65. 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 driving shaft 56 is controlled to rotate by the driving of the first motor 55. At this time, the two sets of driven shafts 51 are synchronously rotated by the transmission function of the transmission component 57. When the driven shaft 51 rotates, the sleeve block 52 and the protrusion 53 are controlled to rotate at the same time. As the protrusion 53 follows the sleeve block 52 to rotate around the driven shaft 51, the protrusion 53 contacts and abuts against the protrusion 54 during the rotation process, thereby controlling the rotation of the rotating arm 42 at the same time. 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. When the impact column 45 moves upward, the hammer head 46 and the first counterweight block 48 move upward, and control the compression of the spring 49. When the protrusion 53 rotates to the highest point, the protrusion 54 is disengaged from the protrusion 53 due to the elastic force of the spring 49. At this time, through the mutual 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 the crusher 1 may also be equipped with a sensor, the sensor is connected to the controller 3 via telecommunication, and the first motor 55 and the second motor 66 are both connected to the controller 3 via telecommunication;

[0057] Among them, 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, the load changes of the fixed jaw plate 12 and the movable jaw plate 14 during operation can be monitored 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 condition according to a preset threshold value. When the load exceeds the set threshold value, the controller 3 reacts and first controls 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 head 46 to move as a whole to the top of the crushing chamber, the controller 3 sends a power-off signal to stop the operation of the second motor 66. Then the controller 3 controls the first motor 55 to run. When the first motor 55 runs, the hammer head 46 is controlled to move up and down to hammer the marble block.

[0058] The sensor can also be a displacement sensor installed on the movable jaw plate 14. When the sensor is a displacement sensor, the displacement sensor will sense the relative displacement of the movable jaw plate 14 during operation and convert it into an electrical signal. The displacement sensor transmits the measured displacement signal to the controller 3. The controller 3 determines the working state of the movable jaw plate 14 based on the received displacement signal. When the displacement signal is abnormal, the controller 3 reacts and first controls 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 head 46 to move as a whole to the top of the crushing chamber, the controller 3 sends a power-off signal to stop the operation of the second motor 66. Then the controller 3 controls the first motor 55 to run. When the first motor 55 runs, it controls the hammer head 46 to move up and down to hammer the marble block.

[0059] Through intelligent control among the sensor, the controller 3, the first motor 55 and the second motor 66, the real-time monitoring and control of the sensor can be utilized to effectively optimize the crushing process and improve the overall production efficiency.

[0060] Further, see Figure 11-Figure 12 , a striking mechanism 7 is provided on the impact column 45;

[0061] The striking mechanism 7 comprises a fixing ring 71 fixed on the impact column 45, a connecting frame 72 symmetrically fixed at the front and rear positions of the fixing ring 71, a shaft 73 rotatably arranged on the connecting frame 72 through a bearing, 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, wherein the positions of the front and rear groups of shovel heads 75 are offset from each other. When the swing arm 74 drives the shovel heads 75 to swing back and forth, the positions of the front and rear groups of shovel heads 75 are offset from each other, so that collision between the front and rear groups of shovel heads 75 can be avoided.

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

[0063] Specifically, the knocking mechanism 7 also includes a gear 77 fixed on the shaft rod 73 and a toothed plate 78 fixed on the bottom end of the sleeve 47. When the impact column 45 moves, the gear 77 meshes with the toothed plate 78, and the toothed plate 78 is located on the inner side of the gear 77. A torsion spring 79 is also provided on the shaft rod 73, and the two ends of the torsion spring 79 respectively abut against the end faces of the connecting frame 72 and the gear 77. When the impact column 45 drives the hammer head 46 to move downward, it can also control the fixing ring 71, the connecting frame 72, the shaft rod 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 rod 73 and the swing arm 74 to rotate. At this time, the swing arm 74 located at the front and rear positions of the fixing ring 71 drives the shovel head 75 to swing inward. Due to the positions of the front and rear groups of shovel heads 75 The shovel head 75 is offset from each other, so there is no collision when the shovel head 75 swings inward, and at the same time, the torsion spring 79 accumulates force. When the gear 77 and the tooth plate 78 are disengaged, the torsion spring 79 is released after the accumulated force, and the swing arm 74 is controlled to drive the shovel head 75 to swing outward. The swing of the shovel head 75 can simultaneously achieve the dual effects of hammering and pushing. While participating in the crushing, the shovel head 75 can push the loosened stones outward, further reducing the occurrence of jams, and the swing of the shovel head 75 can increase the knocking 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 movement can be used to work together, thereby improving the crushing effect of the marble blocks stuck between the fixed jaw plate 12 and the movable jaw plate 14, thereby accelerating the removal speed of the marble blocks.

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

[0065] A baffle 741 for limiting the swing arm 74 is also fixed to the bottom end of the sleeve 47. The baffle 741 is designed in an arc shape on the upper and lower sides close to the swing arm 74. By providing the baffle 741, when the impact column 45 controls the hammer head 46, the fixing ring 71, the connecting frame 72, the shaft rod 73, the swing arm 74 and the shovel head 75 to move upward as a whole, the gear 77 will still engage with the tooth plate 78 during the upward movement of the shovel head 75, so that the spring 49 accumulates force again. When the gear 77 is disengaged from the tooth plate 78, the swing arm 74 can contact the baffle 741, and the swing of the swing arm 74 and the shovel head 75 can be limited by the action of the baffle 741.

[0066] During use, since the fixing ring 71 is fixed to the lower part of the shovel head 75 located at the sleeve 47, when the impact column 45 controls the hammer head 46 to move downward, the fixing ring 71, the connecting frame 72, the shaft rod 73, the swing arm 74, the shovel head 75, the second counterweight block 76, the gear 77 and the torsion spring 79 move downward with the impact column 45 at the same time. When the gear 77 moves to the tooth plate 78, the gear 77 meshes with the tooth plate 78, so that the gear 77 drives the shaft rod 73, the swing arm 74, the shovel head 75, the second counterweight block 76, the gear 77 and the torsion spring 79 to move downward with the impact column 45. The second counterweight block 76 rotates inward, and the torsion spring 79 accumulates force. As the shovel head 75 continues to move downward, when the gear 77 and the tooth plate 78 are disengaged, the torsion spring 79 accumulates force and then releases it. At this time, the swing arm 74 is controlled to drive the shovel head 75 to swing outward, and the inertia of the swing of the shovel head 75 is increased by the second counterweight block 76, so that the shovel head 75 swings back and forth to knock on irregular marble blocks. At the same time, it can also push the gravel that falls on the stuck marble blocks, further reducing the occurrence of jams.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
