[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figure 1 , Figure 2 , Figure 3As shown in the figure, a crusher for mining includes a crusher body 1; a first servo motor 11 is fixedly connected to the side wall of the crusher body 1; a first gear 12 is fixedly connected to the output end of the first servo motor 11; a first rotating shaft 14 is rotatably connected to the side wall of the crusher body 1; a second gear 13 is fixedly connected to the side wall of the first rotating shaft 14; the first gear 12 and the second gear 13 are meshed with each other; a first sieve plate 15 is fixedly connected to the side wall of the first rotating shaft 14; a first sliding groove 18 is formed in the side wall of the crusher body 1; a crushing material receiving plate 16 is slidably connected to the middle of the first sliding groove 18; a first gear groove 17 is formed at the end of the crushing material receiving plate 16; the first gear groove 17 is meshed with the first gear 12; a second sliding groove 19 is formed in the side wall of the crusher body 1; a blocking plate 110 is slidably connected to the middle of the second sliding groove 19; a discharge plate 112 is fixedly connected to the side wall of the crusher body 1; a conveyor belt 113 is rotatably connected to the side wall of the crusher body 1; during operation, when the material is broken, it falls onto the end of the first sieve plate 15 through the sieve plate. The large pieces of material are left at the end of the first sieve plate 15 through the first sieve plate 15, the finely crushed material falls onto the end of the crushing material receiving plate 16, and the small pieces of material slide along the inclined direction of the crushing material receiving plate 16 and fall onto the discharge plate 112. Every once in a while, the staff pushes the blocking plate 110 to slide in the middle of the second sliding groove 19, so that the blocking plate 110 temporarily closes the sieve plate to prevent it from continuing to drop the material. At this time, the first servo motor 11 is started, and the first gear 12 is driven to rotate by the output end of the first servo motor 11, and then the second gear 13 is driven. At this time, the second gear 13 drives the first rotating shaft 14 to rotate, and then the first sieve plate 15 rotates to form an inclined angle. During this process, the first gear 12 synchronously drives the crushing material receiving plate 16 to move horizontally in the middle of the first sliding groove 18, so that the crushing material receiving plate 16 does not hinder the rotation of the first sieve plate 15. As a result, the large pieces of material slide onto the end of the conveyor belt 113 and are conveyed to the required position through the conveyor belt 113. After a specified time, the first servo motor 11 rotates back to make the first sieve plate 15 return to the starting position. At this time, the staff pulls the blocking plate 110 to make the blocking plate 110 no longer block the material from falling. This step, through the use of the first sieve plate 15 and the crushing material receiving plate 16, is beneficial to distinguish the crushed material and the large pieces of material, improve the screening speed, and save the screening time. Through the discharge plate 112 and the conveyor belt 113, it is beneficial to separately collect the crushed material and the large pieces of material, reduce the uneven product quality caused by the mixing of the materials together, and is beneficial to improving the product quality.

[0030] As Figure 1 , Figure 4 , Figure 5 , Figure 6As shown in the figure, a second servo motor 2 is fixedly connected to the end of the crusher body 1; a first transmission wheel 21 is fixedly connected to the output end of the second servo motor 2; a belt 22 is rotatably connected to the side wall of the first transmission wheel 21; a winch 23 is rotatably connected to the side wall of the belt 22; a first rope 24 is rotatably connected to the side wall of the winch 23; a second rope 25 is fixedly connected to the end of the first rope 24; a first rope rotating shaft 29 is rotatably connected to the side wall of the second rope 25; a feeding box 28 is fixedly connected to the end of the first rope rotating shaft 29; a 215 is rotatably connected to the side wall of the feeding box 28; a third gear 26 is rotatably connected to the side wall of the 215; a second gear groove 27 is formed in the side wall of the crusher body 1; the third gear 26 is engaged with the second gear groove 27; a second rope rotating shaft 210 is fixedly connected to the side wall of the feeding box 28; a first torsion spring 211 is rotatably connected to the side wall of the feeding box 28; a rope fixing table 212 is fixedly connected to the end of the crusher body 1; a third rope 213 is fixedly connected to the side wall of the rope fixing table 212; the end of the third rope 213 is fixedly connected to the side wall of the second rope rotating shaft 210; during operation, the staff puts the material to be processed into the feeding box 28. At this time, the second servo motor 2 is started, and the output of the second servo motor 2 drives the first transmission wheel 21 to rotate. Through the transmission of the belt 22, the winch 23 rotates on the side wall of the crusher body 1, so that the first rope 24 is wound around the side wall of the winch 23, and then the feeding box 28 rises. At the same time, the third gear 26 rises synchronously along the second gear groove 27. When the feeding box 28 reaches below the side wall of the winch 23, at this time, the third rope 213 forms a downward pulling force on the feeding box 28, so that the feeding box 28 rotates and tilts on the side wall of the 215. At this time, the material rushes outwards from the side wall of the feeding box 28 under the action of gravity. Due to the property of the first torsion spring 211, the side wall of the feeding box 28 opens, and the material enters the inside of the crusher body 1. In this step, through the use of the second servo motor 2 and the feeding box 28, the material is fed into the inside of the crusher body 1, which is beneficial to improving the work efficiency of the staff, reducing the direct contact between the staff and the crushing equipment, and reducing the safety risks in the production process. Through the combined use of the third gear 26 and the second gear groove 27, it is beneficial to improve the stability of the feeding box 28 during the rising process, and then reduce the shaking of the feeding box 28.

[0031] As Figure 6 , Figure 7As shown in the figure, a second sieve plate 3 is rotatably connected to the side wall of the crusher body 1; a sieve plate hole 31 is provided at the end of the second sieve plate 3; a first receiving plate 32 is fixedly connected to the side wall of the crusher body 1; a cylinder 33 is fixedly connected to the end of the first receiving plate 32; a spring fixing rod 34 is fixedly connected to the end of the first receiving plate 32; an inserting and rotating shaft 35 is rotatably connected to the side wall of the crusher body 1; during operation, when the material enters the inside of the crusher body 1 and is above the second sieve plate 3, the cylinder 33 jacks up and pulls down the second sieve plate 3 to rotate on the side wall of the inserting and rotating shaft 35, thereby forming a shaking of the material. When it is pulled down, the second sieve plate 3 forms an inclined angle to make the material shake and enter the crushing chamber. At this time, impurities such as soil on the material enter the middle of the first receiving plate 32 through the sieve plate hole 31 in the middle of the second sieve plate 3. When it is necessary to clean the impurities at the end of the first receiving plate 32, the staff lifts the second sieve plate 3 to rotate on the side wall of the inserting and rotating shaft 35. This step, through the cooperation of the cylinder 33 and the second sieve plate 3, is beneficial to reducing the impurities of the material. When the material with a high percentage of moisture or adhered with soil, the discharge sieve plate is easily blocked. This process is beneficial to reducing the situation that the material blocks the discharge hole after crushing, beneficial to reducing the impurities contained in the finished product, and improving the product quality. Through the blocking effect formed by the second sieve plate 3 and the feed inlet, it plays a buffering role when the material enters the cavity, which is beneficial to reducing the direct impact of the material on other metal components in the crushing cavity, and then improving the service life of the metal.

[0032] As Figure 8 , Figure 9 shown, a dust suction cavity 4 is fixedly connected to the side wall of the crusher body 1; a first blocking plate 41 is fixedly connected to the side wall of the crusher body 1; a fan 42 is fixedly connected to the side wall of the dust suction cavity 4; a pipe 43 is fixedly connected to the side wall of the dust suction cavity 4; a collection box 44 is fixedly connected to the end of the crusher body 1; a filter screen 45 is fixedly connected to the side wall of the collection box 44; an exhaust pipe 46 is fixedly connected to the side wall of the collection box 44; during operation, when the crusher body 1 is working, the fan 42 rotates, sucking the dust and fine particles generated during the crushing process into the cavity of the dust suction cavity 4 and entering the inside of the collection box 44 along the pipe 43. When it passes through the filter screen 45, the fine particles are filtered, and the gas is discharged by the exhaust pipe 46. This step is beneficial to reducing the dust generated during the operation of the crusher body through this process. By filtering the fine particles, it is beneficial to reducing the diseases of the staff caused by the dust.

[0033] As Figure 10As shown, a rotating handle 5 is rotatably connected to the side wall of the feeding box 28; a limiting plate 52 is fixedly connected to the side wall of the feeding box 28; a joint plate 53 is fixedly connected to the side wall of the feeding box 28; a plate groove 54 is formed in the side wall of the joint plate 53; a drag reduction port 55 is formed in the side wall of the joint plate 53; a second torsion spring 56 is slidably connected to the side wall of the rotating handle 5; when the staff cleans the feeding box 28 during work, the second torsion spring 56 is pushed to slide into the cavity of the rotating handle 5. At this time, the rotating handle 5 is toggled to rotate on the side wall of the feeding box 28 to open the side wall of the feeding box 28. When the cleaning is completed, the rotating handle 5 is toggled to rotate to the side wall of the feeding box 28. At this time, the limiting plate 52 limits the rotating handle 5, and the second torsion spring 56 is pushed to enter the cavity of the drag reduction port 55 along the plate groove 54 to achieve locking. This step is beneficial for the staff to clean and discharge the stains inside the feeding box 28 by opening and closing the side wall of the feeding box 28, thereby improving the working efficiency of the staff in cleaning the feeding box 28.

[0034] As Figure 1 , Figure 6 As shown, a third torsion spring 6 is fixedly connected to the side wall of the crusher body 1; a second blocking plate 61 is rotatably connected to the side wall of the third torsion spring 6; a limiting head 62 is fixedly connected to the end of the second blocking plate 61; a limiting groove 63 is formed at the end of the crusher body 1; when the material is conveyed to the feeding port during work, the second blocking plate 61 slides inward along the limiting groove 63 due to the gravity effect. At this time, the material enters the crushing cavity. When the material stops entering, the second blocking plate 61 is reset due to the property of the third torsion spring 6. This step, by using the third torsion spring 6 and the second blocking plate 61, is beneficial for reducing the flying of broken materials generated by the impact of the material in the cavity.

[0035] As Figure 1 , Figure 4 , Figure 6 As shown, a connecting plate 7 is fixedly connected to the middle of the conveyor belt 113; a spring 71 is fixedly connected to the end of the connecting plate 7; a replacement belt 72 is fixedly connected to the end of the spring 71; when the material falls from the first sieve plate 15 during work, the kinetic energy of the falling material is reduced by the property of the spring 71. This step is beneficial for reducing the damage caused by the falling material to the conveyor belt 113 and extending the service life of the conveyor belt 113.

[0036] Working principle: during operation, after the material is broken, it falls through the sieve plate to the end of the first sieve plate 15, and the large pieces of material are left at the end of the first sieve plate 15 through the first sieve plate 15, and the finely crushed materials fall to the end of the crushed material receiving plate 16, and the small pieces of material slide along the inclined direction of the crushed material receiving plate 16 and fall to the discharge plate 112. At regular intervals, the staff pushes the blocking plate 110 to slide in the middle of the second sliding groove 19, so that the blocking plate 110 temporarily closes the sieve plate to prevent it from continuing to fall. At this time, the first servo motor 11 is started, and the output end of the first servo motor 11 drives the first gear 12 to rotate, and then drives the second gear 13. At this time, the second gear 13 drives the first rotating shaft 14 to rotate, so that the first sieve plate 15 rotates to form an inclined angle. During the screening process, the first gear 12 synchronously drives the crushed material receiving plate 16 to move horizontally in the middle of the first sliding groove 18, so that the crushed material receiving plate 16 will not hinder the rotation of the first screen plate 15, thereby allowing the large pieces of material to slide to the end of the conveyor belt 113 and be conveyed to the desired position via the conveyor belt 113. After a specified time, the first servo motor 11 rotates to restore the first screen plate 15 to the starting position. At this time, the staff pulls the blocking plate 110 so that the blocking plate 110 no longer blocks the material from falling. This step is conducive to distinguishing crushed materials from large pieces of material through the use of the first screen plate 15 and the crushed material receiving plate 16, thereby improving the screening speed and saving the screening time. Through the discharge plate 112 and the conveyor belt 113, it is conducive to collecting the crushed materials and large pieces of material separately, reducing the risk of material mixing. The uneven product quality caused by the combination is beneficial to improving the product quality. During work, the staff puts the material to be processed into the feeding box 28, and then starts the second servo motor 2. The output of the second servo motor 2 drives the first transmission wheel 21 to rotate, and the belt 22 is used to drive the capstan 23 to rotate on the side wall of the crusher body 1, so that the first rope 24 is wound around the side wall of the capstan 23, and then the feeding box 28 rises. At the same time, the third gear 26 rises synchronously along the second gear groove 27. When the feeding box 28 reaches the bottom of the side wall of the capstan 23, the third rope 213 forms a downward pulling force on the feeding box 28, so that the feeding box 28 rotates and tilts on the side wall 215. At this time, the material rushes out from the side wall of the feeding box 28 due to gravity. The nature of 211 makes the side wall of the feed box 28 open, allowing the material to enter the crusher body 1. In this step, the second servo motor 2 and the feed box 28 are used to feed the material into the crusher body 1, which is beneficial to improving the work efficiency of the staff, reducing the direct contact between the staff and the crushing equipment, and reducing the safety risks in the production process. The coordinated use of the third gear 26 and the second gear groove 27 is beneficial to improving the stability of the feed box 28 during the rising process, thereby reducing the shaking of the feed box 28. During operation, when the material enters the crusher body 1 and is on the upper part of the second screen plate 3, the cylinder 33 lifts and pulls down the second screen plate 3 to rotate on the side wall of the inserted rotating shaft 35, thereby causing the material to shake. When it is pulled down,The second sieve plate 3 forms an inclined angle so that the material shakes and enters the crushing chamber. At this time, impurities such as soil on the material enter the middle of the first receiving plate 32 through the sieve plate hole 31 in the middle of the second sieve plate 3. When it is necessary to clean the impurities at the end of the first receiving plate 32, the staff lifts the second sieve plate 3 and rotates it on the side wall of the plug-in rotating shaft 35. This step is beneficial to reduce material impurities through the coordinated use of the cylinder 33 and the second sieve plate 3. When the material contains a high percentage of moisture or is sticky with soil, the discharge sieve plate is easily blocked. This process is beneficial to reduce the situation where the material blocks the discharge hole after crushing, and is beneficial to reduce the impurities contained in the finished product, thereby improving the crushing efficiency. High product quality, through the blocking effect formed by the second screen plate 3 and the feed port, the material plays a buffering role when entering the cavity, which is beneficial to reduce the direct impact of the material on other metal structures in the crushing cavity, thereby improving the service life of the metal. When the crusher body 1 is working, the fan 42 rotates, and the smoke and tiny particles generated during the crushing process are sucked into the dust suction chamber 4 along the pipe 43 into the collection box 44. When it passes through the filter screen 45, the tiny particles are filtered, and the gas is discharged from the exhaust pipe 46. This step is beneficial to reduce the smoke and dust generated during the working process of the crusher body through this process. By filtering the tiny particles, The second torsion spring 56 is pushed along the plate groove 54 into the cavity of the drag reduction port 55 to achieve locking. This step facilitates the staff to clean and discharge the stains inside the feeding box 28 by opening and closing the side wall of the feeding box 28, thereby improving the cleaning efficiency of the staff. The working efficiency of the feeding box 28 is improved. When the material is transported to the feed port, the blocking plate 2 61 slides inward along the limit groove 63 due to the gravity effect. At this time, the material enters the crushing cavity. When the material stops entering, the blocking plate 2 61 is reset due to the nature of the third torsion spring 6. This step is conducive to reducing the flying of broken materials caused by the material being hit in the cavity through the use of the third torsion spring 6 and the blocking plate 2 61. When the material falls from the first screen plate 15 during operation, the kinetic energy of the material falling is reduced by the nature of the spring 71. This step is conducive to reducing the damage to the conveyor belt 113 caused by the falling material and extending the service life of the conveyor belt 113.
