A first crushing roller is fixedly installed on the left end of the motor.

[0003] The main problem with the existing crushing equipment used in mining machinery is that after crushing the ore, it cannot effectively separate the ore of acceptable particle size from the still larger, unacceptable ore. This lack of sorting function prevents the equipment from collecting and recycling the larger, unacceptable ore separately, affecting overall operational efficiency and resource utilization. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a crushing equipment for underground mining machinery. After crushing the ore, the device can classify the ore with qualified particle size from the ore with unqualified particle size, so as to facilitate the recycling of the ore with unqualified particle size and improve the operation efficiency and resource utilization rate.

[0005] To solve this technical problem, the present invention adopts the following technical solution: A crushing device for underground mining machinery includes a shell assembly, which includes a fixed shell. The upper inner side of the fixed shell is provided with a crushing component for crushing ore. Below the crushing component, there are several wedge-shaped fixed seats. The higher side wall of each fixed seat is fixed to the inner side wall of the fixed shell, which is used to guide the crushed ore into the position between all the fixed seats. The fixed base is provided with a sliding frame below it, and a vibration motor is provided on the sliding frame; several guide rods are provided around the sliding frame, each guide rod passing through the fixed shell and slidably connected to the fixed shell, and each guide rod is also fitted with a spring; a sieve plate is slidably arranged inside the sliding frame, and the bottom of the sliding frame is hollow at the position corresponding to the sieve plate; several electric push rods are provided on the sieve plate, and the output end of each electric push rod is fixedly connected to the bottom of the sieve plate. The lower side of the sliding frame is provided with several arc-shaped collection racks. The upper end of each collection rack is located at the bottom of the sliding frame, and the lower end of each collection rack is fixed to the inner wall of the fixed shell. A fixed square tube is opened on the side wall of the fixed shell corresponding to the lower end of each collection rack, which is used to collect ore with unqualified particle size.

[0006] Preferably, the crushing assembly includes two crushing rods arranged side by side, each crushing rod having a plurality of crushing protrusions circumferentially arranged; two drive motors are provided on the outer wall of the fixed shell, and the output ends of the drive motors are respectively connected to the corresponding crushing rods.

[0007] Preferably, a guide plate is provided below the sliding frame. The guide plate has an isosceles triangular structure, with the apex of the guide plate located directly below the center of the sieve plate, and the bottom edge of the guide plate fixed to the inner bottom surface of the fixed base.

[0008] Preferably, the bottom of the sliding frame is provided with connecting protrusions corresponding to the positions of each guide rod. Each guide rod is arranged horizontally, one end of each guide rod is fixed to the corresponding connecting protrusion, and the other end of each guide rod is provided with a limiting block. Each limiting block is located on the outside of the fixed shell. Each spring is located between each connecting protrusion and the inner wall of the fixed shell.

[0009] Preferably, the bottom of the sieve plate is further provided with several guide posts, each guide post passing through the bottom of the sliding frame and slidably connected to the sliding frame; each guide post has a limiting protrusion at its bottom end, and each limiting protrusion is located on the outer side of the bottom of the sliding frame.

[0010] Preferably, the sieve plate has a plurality of equidistantly arranged screening holes, and the sieve plate has a four-sided pyramidal structure, which is used to screen out ores that do not meet the particle size requirements and separate them to the edges around the sieve plate.

[0011] Preferably, the bottom of the fixed shell is provided with several support legs.

[0012] The positive effects of this utility model are as follows: First, by setting up a sliding frame and a sieve plate, this utility model enables the sliding frame to start vibrating in the fixed shell after the ore is crushed by starting the vibration motor. After the crushed ore is screened by the sieve plate, the ore with qualified particle size can be quickly classified into qualified and unqualified ore.

[0013] Secondly, this utility model, by setting an electric push rod at the bottom of the screen plate, after the ore is sorted, activates the electric push rod to move the screen plate upward in the sliding frame. When the screen plate moves to be level with the top edge of the sliding frame, the ore that does not meet the particle size requirements will fall from all sides of the screen plate, be caught by the collecting frame, and then discharged to the outside of the fixed shell through the fixed square tube. This realizes the recycling of ore that does not meet the particle size requirements, improving work efficiency and resource utilization.

[0014] Third, by setting guide columns, this utility model limits the sliding range of the sieve plate, preventing the sieve plate from sliding out of the sliding frame and improving the stability of the sieve plate's up and down movement.

[0015] Fourth, by setting a triangular guide plate, this utility model can gather the ore with qualified particle size after being screened by the sieve plate to the side of the guide plate, which is convenient for subsequent recycling and application.

[0016] Fifth, by setting a guide rod, this utility model can provide a certain buffering effect on the vibrating sliding frame, preventing the fixed shell from vibrating along with the sliding frame, thus improving the overall stability and safety of the device.

[0017] Sixth, by setting a fixed base, this utility model can guide the crushed ore to the top of the classification component (especially the screen plate) below, ensuring that all ore can be screened by the classification component (especially the screen plate), improving the comprehensiveness of ore screening, and further improving the working efficiency and effectiveness of this device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model includes a housing assembly 1, which includes a rectangular fixed shell 12. The top of the fixed shell 12 has a feeding port, and inclined baffles are provided on both sides of the feeding port to prevent the ore from splashing out after crushing. A support leg 1201 is provided at each of the four corners of the bottom of the fixed shell 12 to support the fixed shell 12.

[0022] The upper inner side of the fixed shell 12 is provided with a crushing assembly 9 for crushing ore. The crushing assembly 9 includes two parallel crushing rods 15, each of which has several crushing protrusions around its circumference for crushing the ore by compression. Two drive motors 14 are provided on the outer wall of the fixed shell 12, and the output ends of the drive motors 14 are connected to the corresponding crushing rods 15. When the drive motors 14 are started, the two drive motors 14 drive the two crushing rods 15 to rotate in opposite directions, that is, the two crushing rods 15 rotate towards each other, and together exert inward force to crush the ore.

[0023] Four wedge-shaped fixing seats 13 are respectively provided on the four side walls of the fixed shell 12 below the crushing component 9. The higher side wall of each fixing seat 13 is fixed to the inner side wall of the fixed shell 12, which is used to guide the crushed ore into the position between all the fixing seats 13. By setting the fixing seats 13, the crushed ore can be guided directly above the sorting component (especially the screen plate 5) below, ensuring that all the ore can be screened by the sorting component (especially the screen plate 5), improving the comprehensiveness of ore screening, and further improving the working efficiency and effectiveness of this device.

[0024] A sliding frame 2 is provided below the fixed base 13, and a vibration motor 3 is located at the center of the bottom of the sliding frame 2. Four guide rods 6 are provided around the bottom of the sliding frame 2 corresponding to the four side walls of the fixed shell 12. Each guide rod 6 penetrates the corresponding side wall of the fixed shell 12 and is slidably connected to it. A spring 7 is also fitted onto each guide rod 6. Connecting protrusions are also provided on the lower side of the sliding frame 2 corresponding to the positions of each guide rod 6. Each guide rod 6 is horizontally positioned, with one end fixed to the corresponding connecting protrusion and the other end of each guide rod 6 having a limiting block located on the outer side of the corresponding side wall of the fixed shell 12. Each spring 7 is located between the connecting protrusion and the inner wall of the corresponding side wall of the fixed shell 12. By providing the guide rods 6, the vibrating sliding frame 2 can be buffered, preventing the fixed shell 12 from vibrating along with the sliding frame 2, thus improving the overall stability and safety of the device.

[0025] A sieve plate 5 is slidably mounted inside the sliding frame 2. The sieve plate 5 has several equidistantly arranged screening holes and is a four-sided pyramidal structure (higher in the middle and lower around the edges). This structure is used to screen out ores that do not meet the particle size requirements, allowing them to fall to the edges of the sieve plate 5. The bottom of the sliding frame 2 is hollow, corresponding to the position of the sieve plate 5, to facilitate the ore falling into the bottom of the fixed shell 12 after passing through the sieve plate 5. By setting up the sliding frame 2 and the sieve plate 5, after the ore is crushed, starting the vibration motor 3 causes the sliding frame 2 to vibrate within the fixed shell 12. After the crushed ore is screened through the sieve plate 5, ores of acceptable particle size can be quickly separated from those of unacceptable particle size.

[0026] The sieve plate 5 is equipped with two electric push rods 4, the output end of each electric push rod 4 being fixedly connected to the bottom of the sieve plate 5. The two electric push rods 4 are arranged side by side at a certain distance on the center line of the sieve plate 5. The lower side of the sliding frame 2 is provided with four arc-shaped converging frames 11 corresponding to the four side walls of the fixed shell 12. The upper end of each converging frame 11 is located at the bottom of the sliding frame 2, and the lower end of each converging frame 11 is fixed to the inner side of the corresponding side wall of the fixed shell 12. An L-shaped fixed square tube 10 is provided on the side wall of the fixed shell 12 corresponding to the lower end of each converging frame 11. The fixed square tube 10 connects the interior of the fixed shell 12 to the outside, and is used to discharge and collect ore with unqualified particle size to the outside of the fixed shell 12.

[0027] By installing an electric push rod 4 at the bottom of the screen plate 5, after the ore is sorted, the electric push rod 4 is activated, which enables the screen plate 5 to move upward in the sliding frame 2. When the screen plate 5 moves to be flush with the top edge of the sliding frame 2, the ore that does not meet the particle size requirements will fall from all sides of the screen plate 5, be caught by the collecting frame 11, and then discharged to the outside of the fixed shell 12 through the fixed square tube 10. This realizes the recycling of ore that does not meet the particle size requirements, improving the efficiency of operation and the utilization rate of resources.

[0028] The bottom of the sieve plate 5 is also provided with two guide posts 16. Each guide post 16 penetrates the bottom of the sliding frame 2 and is slidably connected to the sliding frame 2. The two guide posts 16 are arranged side by side at a certain distance on the center line of the sieve plate 5. Each guide post 16 has a limiting protrusion at its bottom end, and each limiting protrusion is located on the outer side of the bottom of the sliding frame 2. By setting the guide posts 16, the sliding range of the sieve plate 5 is limited, preventing the sieve plate 5 from sliding out of the sliding frame 2 and improving the stability of the sieve plate 5's up and down movement.

[0029] Below the sliding frame 2, there is also a guide plate 8. The guide plate 8 has an isosceles triangular structure, with its apex located directly below the center of the screen plate 5, and its base fixed to the inner bottom surface of the fixing base 13. By setting the triangular guide plate 8, the ore with qualified particle size after being screened by the screen plate 5 can be gathered to the side of the guide plate 8, which is convenient for subsequent recycling.

[0030] The method of using the stone crushing equipment for underground mining machinery described in this utility model is as follows: When ore needs to be crushed and sorted, the drive motor 14 and the vibration motor 3 are started. The two crushing rods 15 begin to rotate in opposite directions, and the sliding frame 2 begins to vibrate. Ore is fed into the device through the feed port at the top of the fixed shell 12. After being crushed by the crushing rods 15, the ore falls into the sliding frame 2 under the guidance of the four fixed seats 13. It is then screened by the screen plate 5: ore with the correct particle size passes through the screen plate 5 and, guided by the guide plate 8, finally falls to the bottom of the fixed shell 12 and is located beside the guide plate 8; ore with the incorrect particle size cannot pass through the screen plate 5 and moves towards the edge of the screen plate 5 under the vibration of the screen plate 5. This completes the crushing of the ore and the sorting of ore with the correct and incorrect particle size.

[0031] When it is necessary to recycle ore with unqualified particle size, the drive motor 14 and the vibration motor 3 are turned off, and the electric push rod 4 is started. The screen plate 5 moves upward in the sliding frame 2, and the guide column 16 moves upward with the screen plate 5. When the screen plate 5 moves to be flush with the top edge of the sliding frame 2 (the guide column 16 reaches its maximum moving distance), the ore with unqualified particle size will fall from all sides of the screen plate 5. After being caught by the collecting frame 11, it will be discharged to the outside of the fixed shell 12 through the fixed square tube 10 (a box for collecting ore is placed below the external outlet of the fixed square tube 10), thus realizing the recycling of ore with unqualified particle size for further processing.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
