[0036] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0037] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0039] A raw material crushing device for gypsum board production according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0040] See also Figure 1-Figure 10 According to an embodiment of the present application, a raw material crushing device for gypsum board production includes: a supporting main body part 1, a raw material crushing mechanism 2 and a gypsum ore crushing pretreatment mechanism 3.

[0041] The supporting body 1 is used to support the raw material crushing mechanism 2 and the gypsum ore crushing pretreatment mechanism 3. The gypsum ore crushing pretreatment mechanism 3 can crush the large pieces of gypsum ore in advance, and then the raw material crushing mechanism 2 can crush the crushed gypsum ore more quickly, thereby improving the crushing efficiency of the equipment.

[0042] See also Figure 1-Figure 5 The supporting main body 1 includes a stand 11 and a column 12. The column 12 is installed under the stand 11 by welding, and a mounting port 13 is provided above the stand 11. The raw material crushing mechanism 2 includes a silo 21, a reduction motor 22, a crushing roller 23 and a chain transmission assembly 24. The silo 21 is installed on the stand 11 located above the mounting port 13, and multiple groups of crushing rollers 23 are rotatably arranged inside the silo 21. The reduction motor 22 is installed above the stand 11, and the output end of the reduction motor 22 is respectively connected to the end of the crushing roller 23 through multiple groups of chain transmission assemblies 24. The gypsum ore crushing pretreatment mechanism 3 includes a lower cover shell 31 of a U-shaped structure, a support leg 32, an upper cover shell 33 of an inverted U-shaped structure, an elastic support assembly 34, a vibration motor 35, a transfer trough 36, an upper trough 38 and a crushing nail 39 of a conical structure. The lower cover 31 is tilted and arranged on one side above the silo 21. The support legs 32 are bolted to connect the lower cover 31 and the stand 11. The upper cover 33 is movably engaged above the lower cover 31, and the side of the upper cover 33 is connected to the lower cover 31 through an elastic support assembly 34. The vibration motor 35 is installed on the top of the upper cover 33, and the transfer trough 36 is tilted and installed at the end of the lower cover 31 away from the silo 21. Multiple groups of crushing nails 39 are staggered and arranged in multiple rows at equal distances vertically on the inner top wall of the upper cover 33, and the multiple rows of crushing nails 39 are gradually extended from the transfer trough 36 to the position of the silo 21. The upper trough 38 is tilted and arranged above the upper cover 33, and the bottom of the upper cover 33 is fixed to the top of the upper cover 33 through a fixing frame 37.

[0043] The working principle of the raw material crushing device for gypsum board production is as follows: the material is transported by a conveyor belt device to the upper trough 38, and the gypsum ore falling above the upper trough 38 will fall into the transfer trough 36 along the inclined upper trough 38, and the gypsum ore in the transfer trough 36 will slide along the transfer trough 36 to between the lower cover shell 31 and the upper cover shell 33. Smaller gypsum ore will slide directly along the lower cover shell 31 into the silo 21 of the raw material crushing mechanism 2. The vibration motor 35 will drive the upper cover shell 33 and the crushing nails 39 to vibrate together, and the larger gypsum ore between the lower cover shell 31 and the upper cover shell 33 will be crushed into small pieces of gypsum, and the small pieces of gypsum will slide along the lower cover shell 31 into the silo 21. That is, large pieces of gypsum ore will be pre-crushed into smaller pieces and then fall into the silo 21. The reduction motor 22 drives the crushing roller 23 to rotate through the chain transmission assembly 24. Multiple sets of rotating crushing rollers 23 can crush smaller pieces of ore more easily and quickly. That is, the raw material crushing device for gypsum board production can effectively improve the gypsum ore crushing efficiency.

[0044] The multiple groups of crushing nails 39 at the top of the upper cover shell 33 are arranged in multiple rows and are evenly spaced vertically on the top wall of the upper cover shell 33, and the multiple rows of crushing nails 39 are gradually extended from the transfer trough 36 to the position of the silo 21. This arrangement can gradually break the large pieces of gypsum ore when the crushing nails 39 slide down on the lower cover shell 31 when the crushing nails 39 vibrate, making it easier to break the large pieces of gypsum ore into small pieces. When the conveyor belt equipment continuously transports the material to the upper trough 38, the gypsum ore hits the upper trough 38 under the action of gravity, and the impact of the gypsum ore on the upper trough 38 will be transmitted to the crushing nails 39 in the upper cover shell 33 through the fixing frame 37. The crushing nails 39 are subjected to a stronger impact, which makes it easier to break the gypsum ore between the lower cover shell 31 and the upper cover shell 33. That is, the crushing nails 39 can impact and crush the gypsum ore in a dual way under the vibration of the vibration motor 35 itself and the impact of the gypsum ore during feeding, thereby improving the crushing capacity of the gypsum ore.

[0045] The use of a single reduction motor 22 and a vibration motor 35 can not only replace the original method of multiple motors driving the crushing rollers 23 one by one to crush large pieces of gypsum ore, but also has high crushing efficiency and reduces the use of motors, while also saving electricity.

[0046] For specific settings, see Figure 1 and Figure 2The supporting body part 1 also includes a ladder frame 14, which is installed on one side of the platform 11. The setting of the ladder frame 14 is convenient for maintenance personnel to go above the platform 11 to perform maintenance work on the equipment components. The supporting body part 1 also includes a handrail 15, which is arranged on the periphery of the platform 11. The setting of the handrail 15 is to improve the safety of maintenance personnel when walking above the platform 11. A bracket fixed to the platform 11 is arranged on the periphery above the installation opening 13, and the reduction motor 22 and the silo 21 are both installed above the bracket. The top opening of the silo 21 is set to expand outward.

[0047] For further information, see Figure 6 The elastic support assembly 34 includes a first support block 341, a second support block 342 and a shock absorber 343. The first support block 341 is fixed to the outside of the lower housing 31 by welding, the second support block 342 is fixed to the outside of the upper housing 33 by welding, and the shock absorber 343 connects the first support block 341 and the second support block 342. The shock absorber 343 between the first support block 341 and the second support block 342 plays a good shock absorbing and buffering role.

[0048] Specifically, see Figure 4 The gypsum ore crushing pretreatment mechanism 3 also includes a support rod 321, which connects the support leg 32 and the transfer trough 36. The support rod 321 is used to assist in supporting the transfer trough 36. The gypsum ore crushing pretreatment mechanism 3 also includes a feed plate 311, which is arranged at the end of the lower cover 31 away from the transfer trough 36, and the bottom end of the feed plate 311 is located above the middle of the silo 21. The feed plate 311 delivers small pieces of gypsum ore to the middle of the silo 21, and the gypsum ore in the silo 21 is more easily crushed by the multiple groups of crushing rollers 23, thereby improving the gypsum ore crushing efficiency.

[0049] Furthermore, the chain transmission assembly 24 includes a chain, a driving sprocket and a driven sprocket. The reduction motor 22 can directly drive one group of crushing rollers 23 to rotate, and the other group of crushing rollers 23 are driven to rotate through the chain, the driving sprocket and the driven sprocket in the chain transmission assembly 24.

[0050] The raw material crushing device for gypsum board production uses crushing nails 39 to crush the gypsum ore from above. If the large gypsum ore can be crushed from above and below at the same time, it is easier to crush the large gypsum ore into small pieces.

[0051] See also Figure 3 , Figure 7 and Figure 8The raw material crushing device for gypsum board production also includes a crushing pre-processing auxiliary mechanism 4, which includes a horizontal strip plate 41, a vertical strip plate 42, a lower nail 43 of a conical structure, a connecting frame 44, a support plate 45, an outer frame plate 46 and a material discharge pipe shell 48. A through hole 312 is provided at the bottom of the lower cover shell 31, and multiple groups of horizontal strip plates 41 and the vertical strip plates 42 are integrally formed and fixedly connected. Multiple groups of lower nails 43 are arranged in rows and staggered and welded above the horizontal strip plates 41, and the connecting frame 44 connects the vertical strip plates 42 and the upper cover shell 33. The support plate 45 is tilted and located below the horizontal strip plates 41, and the outer frame plate 46 connects the side of the support plate 45 with the support leg 32. A notch 47 is provided at the bottom of the end of the support plate 45, and the top of the material discharge pipe shell 48 is connected to the notch 47, and the material discharge pipe shell 48 is installed through the stand 11.

[0052] When a large piece of gypsum ore enters between the lower cover shell 31 and the upper cover shell 33, the vibration motor 35 drives the upper cover shell 33 and the crushing nail 39 to vibrate. When the vibration motor 35 drives the upper cover shell 33 to vibrate, the vibrating upper cover shell 33 also drives the longitudinal strips 42 to vibrate through the connecting frame 44, and the vibrating longitudinal strips 42 will eventually drive the lower nail 43 to vibrate through the transverse strips 41. The top of the vibrating lower nail 43 will pass through the through hole 312 at the bottom of the lower cover shell 31, that is, the lower nail 43 can puncture and crush the bottom of the large piece of gypsum ore that slides on the lower cover shell 31 while being vibrated by the vibration motor 35. At this time, the vibration motor 35 can drive the crushing nail 39 and the lower nail 43 to vibrate at the same time, respectively puncturing the top and bottom of the large piece of ore at the same time, thereby improving the success rate and efficiency of gypsum ore crushing.

[0053] In addition to the vibration of the vibration motor 35 itself driving the crushing nails 39 and the lower nails 43 to vibrate and crush large pieces of gypsum ore, the impact of the gypsum ore transported from the conveyor belt equipment to the upper trough 38 can also drive the crushing nails 39 and the lower nails 43 to vibrate and crush large pieces of gypsum ore, further improving the crushing capacity of the gypsum ore.

[0054] When the lower nail 43 is vibrated to pass through the through hole 312 and pierce the gypsum ore, some fine gypsum ore debris will easily fall out of the through hole 312 on the lower cover shell 31. The gypsum ore debris falling out of the through hole 312 on the lower cover shell 31 will fall onto the support plate 45 below the horizontal strip plate 41. The gypsum ore debris falling on the support plate 45 will enter the slot 47 along the inclined support plate 45, and finally enter the feed pipe shell 48 from the slot 47. The discharge port at the bottom of the feed pipe shell 48 is located below the silo 21, and the gypsum ore debris discharged from the feed pipe shell 48 and the gypsum ore crushed in the silo 21 can be received from below, which not only prevents the debris falling out of the through hole 312 from falling onto the stand 11, but also enables the gypsum ore debris falling out of the through hole 312 to be collected together with the gypsum ore raw materials crushed by the raw material crushing mechanism 2. While the vibration motor 35 drives the lower nail 43 to vibrate and puncture the bottom of the gypsum mine, the end of the lower nail 43 moving in the through hole 312 can also repeatedly pass through the debris in the through hole 312 to prevent the through hole 312 from being blocked by the debris.

[0055] If the raw material crushing device for gypsum board production can be pre-crushed before loading between the lower cover 31 and the upper cover 33, the burden of crushing gypsum ore by the crushing nails 39 can be effectively reduced, and the efficiency of gypsum ore crushing pre-treatment can be further improved.

[0056] See also Figure 3 , Figure 4 , Fig. 9 and Fig.10 The raw material crushing device for gypsum board production also includes a crushing pre-treatment cutting mechanism 5, which includes a roller 51, a cutting blade 52, a belt transmission assembly 53, a shell 54, a fan blade 56, a rotating shaft 57 and a collecting box 59. The roller 51 is rotatably arranged inside the transfer trough 36, and multiple groups of cutting blades 52 are equidistantly arranged outside the roller 51. Ventilation holes 361 are arranged on both sides of the transfer trough 36. One end of the shell 54 is fixedly arranged inside the vent 361. The collecting box 59 is connected and arranged at the bottom of the shell 54. An inner frame 551 and an outer frame 552 are installed on both sides of the shell 54. The rotating shaft 57 is rotatably arranged between the inner frame 551 and the outer frame 552. The fan blades 56 are located inside the housing 54 and are fixedly sleeved outside the rotating shaft 57. The belt transmission assembly 53 connects the shaft end of the roller 51 and the rotating shaft 57. A grid 581 is arranged inside the inner frame 551, and a filter cloth layer 582 is arranged inside the outer frame 552.

[0057] The gypsum ore falling on the upper trough 38 will slide along the upper trough 38 to the cutting blade 52 on the outside of the roller 51 in the transfer trough 36 close to the upper cover shell 33. The cutting blade 52 can pre-cut large pieces of gypsum ore. When the gypsum ore after cutting enters between the lower cover shell 31 and the upper cover shell 33, the ore blocks become smaller and are easier to be pierced and crushed by the crushing nails 39 and the lower nails 43, which can further improve the crushing efficiency of the gypsum ore. The further crushed gypsum ore falls into the crushing roller 23 and is easier to be further crushed and processed.

[0058] The gypsum ore that continuously slides down from the feed chute 38 falls on the cutting blade 52 in front of the roller 51 and is cut and crushed. At the same time, the cutting blade 52 impacted by the gypsum ore will also drive the roller 51 to rotate. The rotating roller 51 will drive the rotating shaft 57 and the fan blade 56 to rotate through the belt transmission assembly 53, and the rotating fan blade 56 will cause air circulation. When the gypsum ore slides down from the feed chute 38 and is cut by the cutting blade 52, it will cause dust diffusion. The rotating fan blade 56 will cause air circulation so that the air inside the transfer chute 36 and the dust are sucked into the shell 54 through the grid 581. The over-pressure air is discharged outward through the filter cloth layer 582, and the dust falls into the collection box 59 at the bottom of the shell 54 and is collected. The crushing pretreatment cutting mechanism 5 uses the impact generated by cutting to drive the fan blade 56 to rotate and collect dust. It operates without the need for additional output equipment, which can reduce the dust generated during cutting and play a certain dust reduction role.

[0059] The belt transmission assembly 53 includes a driving pulley, a driven pulley and a driven pulley, wherein the driving pulley is fixedly sleeved at the end of the roller 51, and the driven pulley is fixedly sleeved at the end of the rotating shaft 57, and the driving belt connects the driving pulley and the driven pulley. The diameter of the driving pulley is at least 10 times the diameter of the driven pulley.

[0060] In the above specific embodiment, the collection box 59 further includes a box body 591 with an open top, a box door 592 and a buckle 593. The top of the box body 591 is connected to the bottom of the shell 54, the box door 592 is hingedly mounted on the outside of the box body 591, and the box door 592 is connected to the box body 591 through the buckle 593. The collected dust falls into the box body 591. When the equipment stops running, the box door 592 can be opened through the buckle 593 to take out the gypsum dust collected in the box body 591.

[0061] It should be noted that the specific model specifications of the above-mentioned reduction motor 22 and vibration motor 35 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
