[0021] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Mineral crushing equipment for mining machinery can crush large pieces of ore or rock into the required particle size as needed to facilitate subsequent processing or use. The shape and size of the material can be changed by crushing, such as preparing sand and gravel aggregates of specific shapes to meet different construction needs. Mineral crushing equipment plays a key role in mining machinery. It is not only related to the rational use of mineral resources, but also directly affects the cost and benefits of the entire production process. Among them, the working principle of mineral crushing equipment is mainly to reduce the particle size of the material through extrusion, impact, splitting and grinding to achieve material crushing. These crushing equipment are widely used in mining, building materials, chemical industry and other industries according to different crushing principles and working characteristics. Mineral crushing equipment plays a vital role in mining. They not only improve the efficiency of ore processing, but also ensure that the quality and shape of the final product meet industrial standards.

[0023] Therefore, please refer to Figure 1-Figure 5As shown, the present embodiment provides a mineral material crushing equipment for mining machinery, including a crusher shell 1. When the mineral material crushing equipment is screening the processed mineral material, the screening efficiency is affected by many factors, among which screen hole blockage is a common problem, which is usually related to the water content of the mineral material. When the water content of the ore is too high, the ore will become sticky and difficult to separate, thereby causing the screen hole blockage and low screening efficiency. Therefore, the details are as follows: a fixed block 22 is fixedly installed on the inner wall of the crusher shell 1 cavity, a spring 21 is fixedly connected above the fixed block 22, a screen 2 is fixedly connected above the spring 21, the inner wall of the fixed block 22 is rotatably connected to a rotating shaft 23, and a fan-shaped block 24 is fixedly installed on the outer wall of the rotating shaft 23. The outer wall of the fan-shaped block 24 is tightly fitted with the lower end of the screen 2, and the fan-shaped block 24 is driven by the rotating shaft 23 to rotate, so as to achieve the up and down vibration of the screen 2, and the crushed mineral material is vibrated and screened. The outer wall of the body 1 is fixedly connected to a motor 11, and an output shaft at an end of the motor 11 is fixedly connected to a first crushing shaft 12. The inner wall of the crusher shell 1 is rotatably connected to a second crushing shaft 13, and the first crushing shaft 12 is meshed with the second crushing shaft 13. The motor 11 drives the first crushing shaft 12 to rotate. Since the first crushing shaft 12 is meshed with the second crushing shaft 13, the second crushing shaft 13 will rotate in the opposite direction, thereby achieving the effect of crushing the mineral material when the mineral material is put into the crusher shell 1. Both ends of the rotating shaft 23 extend out of the crusher shell 1, and both ends of the rotating shaft 23 are fixedly connected to gears 25. The outer wall of the gear 25 at the end of the rotating shaft 23 close to the motor 11 is transmission-connected with a first crawler 251, and the inner wall of the first crawler 251 is transmission-connected to the output shaft at the end of the motor 11. The output shaft at the end of the motor 11 is also transmitted to the gear 25 when rotating, and the gear 25 drives the rotating shaft 23 to rotate, saving labor costs and improving work efficiency.

[0024] Among them, the motor 11 is a motor commonly used in the prior art, and its working principle is: an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. This is common knowledge among people in this technical field and will not be elaborated here.

[0025] The viscous mineral materials attached to the surface of the screen 2 are difficult to be cleaned in time, which may cause the screen 2 to be blocked. The outer wall of the gear 25 at the end of the rotating shaft 23 is away from the motor 11 and is transmission-connected with the second crawler 252. The inner wall of the second crawler 252 is transmission-connected with a screw rod 26. The end of the screw rod 26 extends out of the crusher housing 1. The outer wall of the screw rod 26 is rotationally sleeved with a support frame 27. Two support rods 271 are fixedly connected to the inner wall of the crusher housing 1. The lower part of the support rod 271 is in close contact with the upper part of the support frame 27. A steel brush 28 is fixedly connected to the lower part of the support frame 27. The end of the steel brush 28 is tightly fitted with the upper end of the screen 2. The rotation of the output shaft of the motor 11 drives the rotation of the rotating shaft 23 and the screw rod 26. The support frame 27 is sleeved on the outer wall of the screw rod 26 and is limited by the support rod 271 to move horizontally, driving the steel brush 28 to move horizontally on the upper surface of the screen 2, cleaning the upper surface of the screen 2, and sweeping away the mineral materials attached to the screen 2 to prevent the screen 2 from being blocked.

[0026] The improvement of this embodiment is that:

[0027] The motor 11 drives the fan-shaped block 24 on the rotating shaft 23 to rotate. When the outer wall of the fan-shaped block 24 contacts the lower surface of the screen 2, the screen 2 will be lifted up as the fan-shaped block 24 rotates. When the outer wall of the fan-shaped block 24 leaves the lower surface of the screen 2, the screen 2 is driven by the spring 21 to reset, achieving an up and down vibration effect. When the water content of the ore is too high and the ore is viscous, the ore can be screened by up and down vibration. At the same time, when the screen 2 is lifted up, the steel brush 28 will brush back and forth on the upper surface of the screen 2 to clean the screen 2, preventing a large amount of The viscous mineral material sticks to the screen 2 to improve the work efficiency. A fixed block 22 is fixedly installed on the inner wall of the crusher shell 1 cavity, and a spring 21 is fixedly connected above the fixed block 22. The screen 2 is fixedly connected above the spring 21. The inner wall of the fixed block 22 is rotatably connected to a rotating shaft 23, and a fan-shaped block 24 is fixedly installed on the outer wall of the rotating shaft 23. The outer wall of the fan-shaped block 24 fits tightly with the lower end of the screen 2. The fan-shaped block 24 is driven by the rotating shaft 23 to rotate, thereby achieving the up and down vibration effect on the screen 2, and the crushed mineral material is vibrated and screened.

[0028] In order to enable the mineral crushing equipment to perform crushing work, the outer wall of the crusher shell 1 is fixedly connected to the motor 11, and the output shaft at the end of the motor 11 is fixedly connected to the first crushing shaft 12. The inner wall of the crusher shell 1 is rotatably connected to the second crushing shaft 13. The first crushing shaft 12 is meshed with the second crushing shaft 13, and the first crushing shaft 12 is driven by the motor 11 to rotate. Since the first crushing shaft 12 is meshed with the second crushing shaft 13, the second crushing shaft 13 will rotate in the opposite direction, thereby achieving the effect of crushing the mineral when the mineral is put into the crusher shell 1.

[0029] Considering that it is time-consuming and laborious to rotate the rotating shaft 23 manually, both ends of the rotating shaft 23 extend out of the crusher housing 1, and both ends of the rotating shaft 23 are fixedly connected with gears 25. The outer wall of the gear 25 at the end of the rotating shaft 23 close to the motor 11 is transmission-connected with a first crawler belt 251, and the inner wall of the first crawler belt 251 is transmission-connected to the output shaft at the end of the motor 11. The output shaft at the end of the motor 11 is also transmission-connected to the gear 25 when rotating. The gear 25 drives the rotating shaft 23 to rotate, saving labor costs and improving work efficiency.

[0030] In order to better exert the working effect of the motor 11 and save the use cost, the outer wall of the gear 25 of the rotating shaft 23 away from the motor 11 is connected to the second track 252, and the inner wall of the second track 252 is connected to the screw rod 26. When the motor 11 drives the rotating shaft 23 to rotate, it can also drive the screw rod 26 to rotate.

[0031] Taking into account that the sticky mineral materials attached to the surface of the screen 2 are difficult to clean in time, which may cause the screen 2 to be blocked, the end of the screw rod 26 extends out of the crusher housing 1, and the outer wall of the screw rod 26 is rotatably sleeved with a support frame 27. Two support rods 271 are fixedly connected to the inner wall of the crusher housing 1. The bottom of the support rod 271 is in close contact with the top of the support frame 27. A steel brush 28 is fixedly connected to the bottom of the support frame 27, and the end of the steel brush 28 is tightly fitted with the upper end of the screen 2. The rotation of the output shaft of the motor 11 drives the rotation of the rotating shaft 23 and the screw rod 26. The support frame 27 is sleeved on the outer wall of the screw rod 26 and is limited by the support rod 271 to move horizontally, driving the steel brush 28 to move horizontally on the upper surface of the screen 2, cleaning the upper surface of the screen 2, and sweeping away the mineral materials attached to the screen 2 to prevent the screen 2 from being blocked.

[0032] In summary, the working principle of this scheme is as follows:

[0033] When the mineral material crushing device for mining machinery of the utility model is used, the motor 11 is turned on, the first crushing shaft 12 and the second crushing shaft 13 start to mesh and move, and the mineral material to be processed is put in, and the mineral material will be crushed by the first crushing shaft 12 and the second crushing shaft 13, and the crushed mineral material will fall on the screen 2. Since the first crawler 251 is connected with the end of the motor 11 and the gear 25, the gear 25 will drive the rotating shaft 23 to rotate, and the fan-shaped block 24 on the outer wall of the rotating shaft 23 also starts to rotate. When the outer wall of the fan-shaped block 24 contacts the lower surface of the screen 2, the screen 2 will be lifted up by the fan-shaped block 24. When the outer wall of the fan-shaped block 24 leaves the lower surface of the screen 2, the screen 2 will be The elastic force of the spring 21 drives the reset, and the screen 2 will repeatedly move up and down with the rotation of the motor 11, achieving an up and down vibration effect, so as to screen the mineral materials falling on the screen 2, and the gear 25 at the other end of the rotating shaft 23 will drive the second crawler 252 to transmit, thereby driving the rotation of the screw rod 26, and the support frame 27 rotates on the outer wall of the screw rod 26. The support rod 271 limits the support frame 27 to only horizontal movement, and the end of the steel brush 28 under the support frame 27 is tightly fitted with the lifted screen 2, so the steel brush 28 will clean the mineral materials adhered to the upper surface of the screen 2, and the screened mineral materials are directly discharged from the bottom of the crusher housing 1. After use, the motor 11 can be turned off.
