Description
Technical Field
[0001] The utility model relates to the technical field of medium coal processing, in particular to a medium coal double-roll crusher. Background Technique
[0002] The medium coal double-roll crusher is a crushing device, mainly used for medium and fine crushing operations of coal and other materials. The machine consists of two relatively rotating rollers. When the material passes between the two rollers, it is crushed under the action of extrusion, shearing and bending.
[0003] The existing medium coal selected roughly has relatively large particles and contains gangue coal. To further wash out clean coal from the medium coal, it is necessary to crush the medium coal into particles of 3-5 mm, and then perform separation. If a hammer crusher is used for medium coal crushing, the discharge particle size can be guaranteed, but the output is too low. Moreover, the gangue and stones in the medium coal are also crushed into particles of 3-5 mm, which instead increases the difficulty of medium coal washing. At the same time, in the existing crusher, the material is prone to accumulate at a certain place of the crushing roller during feeding, resulting in poor crushing effect of the material. Summary of the Utility Model
[0004] In order to solve the above technical problems, the utility model provides a medium coal double-roll crusher, which will not crush gangue and stones during medium coal crushing, achieving the effect of reducing the difficulty in subsequent washing and separation. At the same time, it can make the material evenly fall into the interior of the two crushing tooth rollers, improving the crushing effect of the material.
[0005] The technical solution to achieve the purpose of the utility model is: a medium coal double-roll crusher, including a base. On one side of the top of the base, a crushing chamber is fixedly installed. On the top of the crushing chamber, a feeding chamber is fixedly installed. The feeding chamber is internally communicated with the crushing chamber. Inside the crushing chamber, two crushing tooth rollers are movably installed. On the top of the base, two driving motors are fixedly installed. The two driving motors are respectively arranged on both sides of the base. On the output ends of the two driving motors, small belt pulleys are fixedly installed. On both outer sides of the crushing chamber, large belt pulleys are arranged. The two large belt pulleys are respectively fixedly connected to the two crushing tooth rollers. A transmission belt is movably sleeved between the large belt pulley and the small belt pulley on the same side. A vibration mechanism is arranged on the crushing chamber and the feeding chamber.
[0006] In some embodiments, the vibration mechanism includes a vibration plate, a mounting plate, a driving motor and a pressing wheel. The vibration plate is movably installed by embedding inside the feeding chamber. The mounting plate is a rectangular plate, and the mounting plate is fixedly installed above the side wall of the crushing chamber. The driving motor is fixedly installed below the bottom of the mounting plate. The pressing wheel is located above the mounting plate. The pressing wheel has a structure with protrusions on both sides, and the pressing wheel is fixedly connected to the output end of the driving motor.
[0007] In some embodiments, blocking blocks are fixedly installed on both sides of the feeding bin. A movable rod is fixedly installed at a position corresponding to the blocking block on the vibrating plate. The movable rod penetrates through the side wall of the blocking block, and a spring is sleeved on the movable rod.
[0008] In some embodiments, two movable shafts are movably installed inside the vibrating plate. Feeding plates are fixedly sleeved on both movable shafts. Two driving telescopic rods are fixedly installed inside the feeding bin. Limit blocks are fixedly installed at the output ends of the two driving telescopic rods. The tops of the two limit blocks are respectively attached to the bottoms of the two feeding plates.
[0009] In some embodiments, two baffle plates are fixedly installed inside the crushing bin at positions corresponding to the crushing tooth rollers. Movable plates are movably installed at the bottoms of the two baffle plates.
[0010] Compared with the prior art, the remarkable advantages of this utility model are as follows:
[0011] Firstly: In this utility model, when the driving motor is started, the driving motor drives the small pulley to rotate. The small pulley can then drive the large pulley to rotate through the transmission belt. The large pulley then drives the crushing tooth rollers to rotate. The material falls between the two crushing tooth rollers. The material is squeezed between the two crushing tooth rollers, and the medium coal can be crushed. However, the gangue and stones inside the medium coal will not be crushed, which reduces the difficulty for subsequent washing and separation.
[0012] Secondly: This utility model is provided with a vibration mechanism. When the driving motor is started, the driving motor can drive the extrusion wheel to rotate. Since the extrusion wheel has protrusions, the rotation of the extrusion wheel will squeeze the vibrating plate. The vibrating plate will then move inside the feeding bin. At the same time, the spring on the movable rod can be squeezed. Under the action of the spring and the extrusion wheel, the vibrating plate can reciprocate inside the feeding bin. After the material is placed inside the feeding bin, the material will fall on the vibrating plate. The reciprocating movement of the vibrating plate will make the material spread flat on the vibrating plate, so that the material can evenly fall into the two crushing tooth rollers during feeding, improving the effect of material crushing.

Specific implementation manners
[0020] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] The present utility model provides a medium coal double-roll crusher by improvement. The technical solution of the present utility model is as follows:
[0022] As shown in Figure 1 and Figure 2 A medium coal double-roll crusher includes a base 1. One side of the top of the base 1 is fixedly installed with a crushing chamber 2. The crushing chamber 2 is a hollow rectangular structure. The top of the crushing chamber 2 is fixedly installed with a feed bin 3. The feed bin 3 is communicated with the inside of the crushing chamber 2. Two crushing tooth rollers 4 are movably installed inside the crushing chamber 2. The crushing tooth rollers 4 rotate inside the crushing chamber 2. Materials are put into the inside of the crushing chamber 2 through the feed bin 3. The rotation of the crushing tooth rollers 4 will crush the materials. Two driving motors 5 are fixedly installed on the top of the base 1. The two driving motors 5 are respectively arranged on both sides of the base 1. Small pulleys 7 are fixedly installed on the output ends of the two driving motors 5. Large pulleys 6 are arranged on both outer sides of the crushing chamber 2. The two large pulleys 6 are respectively fixedly connected to the two crushing tooth rollers 4. A driving belt 8 is movably sleeved between the large pulley 6 and the small pulley 7 on the same side. A vibration mechanism is arranged on the crushing chamber 2 and the feed bin 3. When the driving motor 5 is started, the driving motor 5 drives the small pulley 7 to rotate. The small pulley 7 can further drive the large pulley 6 to rotate through the driving belt 8. The large pulley 6 drives the crushing tooth rollers 4 to rotate. Materials fall between the two crushing tooth rollers 4. The materials are squeezed between the two crushing tooth rollers 4, and the medium coal can be crushed, while the gangue and stones inside the medium coal will not be crushed, reducing the difficulty for subsequent washing and separation;
[0023] As Figure 1 and Figure 3 shown, in one embodiment, the vibration mechanism includes a vibration plate 11, a mounting plate 12, a drive motor 13, and a pressing wheel 14. The vibration plate 11 is a plate with a rectangular structure. The vibration plate 11 is embedded and movably installed inside the feed bin 3. The mounting plate 12 is a plate with a rectangular structure. The mounting plate 12 is fixedly installed above the side wall of the crushing bin 2. The drive motor 13 is fixedly installed below the bottom of the mounting plate 12. The pressing wheel 14 is located above the mounting plate 12. The pressing wheel 14 is a structure with protrusions on both sides. The pressing wheel 14 is fixedly connected to the output end of the drive motor 13. Blocks 15 are fixedly installed on both sides of the feed bin 3. The blocks 15 are blocks with a rectangular structure. A movable rod 16 is fixedly installed at a position on the vibration plate 11 corresponding to the block 15. The movable rod 16 is a cylindrical structure. The movable rod 16 penetrates through the side wall of the block 15, and a spring is sleeved on the movable rod 16. Through the setting of the vibration mechanism, when the drive motor 13 is started, the drive motor 13 can drive the pressing wheel 14 to rotate. Since the pressing wheel 14 has protrusions, the rotation of the pressing wheel 14 will squeeze the vibration plate 11, and the vibration plate 11 will then move inside the feed bin 3. At the same time, the spring on the movable rod 16 can be squeezed. Under the action of the spring and the pressing wheel 14, the vibration plate 11 can reciprocate inside the feed bin 3. After the material is placed inside the feed bin 3, the material will fall on the vibration plate 11, and the reciprocating movement of the vibration plate 11 will cause the material to be flattened on the vibration plate 11, so that when feeding, the material can evenly fall into the inside of the two crushing tooth rollers 4, improving the effect of material crushing.
[0024] As Figure 2 and Figure 4 shown, in one embodiment, two movable shafts 17 are movably installed inside the vibration plate 11. The movable shafts 17 are cylindrical structures. Feeding plates 18 are fixedly sleeved on both of the two movable shafts 17. The feeding plates 18 are plates with a rectangular structure. Two drive telescopic rods 19 are fixedly installed inside the feed bin 3. Limit blocks 20 are fixedly installed on the output ends of the two drive telescopic rods 19. The tops of the two limit blocks 20 are respectively in contact with the bottoms of the two feeding plates 18. The limit blocks 20 can limit the feeding plates 18. After the material is flattened on the vibration plate 11, the drive telescopic rods 19 can be started. The drive telescopic rods 19 drive the limit blocks 20 to move. After the limit blocks 20 move, the feeding plates 18 will lose the force of being limited. At this time, the material on the vibration plate 11 can fall into the inside of the crushing tooth rollers 4;
[0025] Two baffles 9 are fixedly installed inside the crushing bin 2 at positions corresponding to the crushing tooth rollers 4. The baffles 9 are obliquely arranged rectangular plates. Movable plates 10 are movably installed at the bottoms of the two baffles 9. Through the setting of the baffles 9 and the movable plates 10, the material can be limited by the baffles 9 and the movable plates 10 when feeding, and will not fall to other positions.
[0026] The specific working method is as follows:
[0027] Vibrating mechanisms are provided on the crushing bin 2 and the feeding bin 3. Start the driving motor 5, and the driving motor 5 drives the small pulley 7 to rotate. The small pulley 7 can then drive the large pulley 6 to rotate through the transmission belt 8, and the large pulley 6 drives the crushing tooth roller 4 to rotate. The material falls between the two crushing tooth rollers 4, and the material is squeezed between the two crushing tooth rollers 4. The medium coal can be crushed, while the gangue and stones inside the medium coal will not be crushed, reducing the difficulty for subsequent washing and separation. At the same time, start the driving motor 13, and the driving motor 13 can drive the extrusion wheel 14 to rotate. The extrusion wheel 14 has protrusions, and the rotation of the extrusion wheel 14 will squeeze the vibrating plate 11, and the vibrating plate 11 will then move inside the feeding bin 3. At the same time, the spring on the movable rod 16 can be squeezed. Under the action of the spring and the extrusion wheel 14, the vibrating plate 11 can reciprocate inside the feeding bin 3. After the material is placed inside the feeding bin 3, the material will fall on the vibrating plate 11, and the reciprocating motion of the vibrating plate 11 will flatten the material on the vibrating plate 11, so that the material can uniformly fall into the inside of the two crushing tooth rollers 4 during feeding, improving the effect of material crushing.
