Description

Technical Field

[0001] This utility model relates to the field of material screening technology, and in particular to a screening device for mining ultra-hard inorganic filling and reinforcement materials. Background Technology

[0002] Mining ultra-hard inorganic filling and reinforcement materials are key materials used in mine operations for roadway support and goaf treatment. They are formulated from inorganic minerals such as high-alumina cement and gypsum through a special process. They have the characteristics of high strength, rapid curing and high durability, which can ensure safe production in mines. However, the particle size uniformity of the material directly affects its reinforcement effect, so precise screening of the material is particularly important.

[0003] A search revealed Chinese Patent Publication No. CN219483381U, which discloses a cement screening device and its usage method, including a screening processing machine, a screening mechanism fixedly connected to the outside of the screening processing machine, and support feet fixedly connected to the outside of the screening processing machine. This invention utilizes a handle externally connected to the feed box to rotate a first rotating rod, which in turn rotates a first half-gear, causing a first baffle to rotate. A second half-gear, externally meshed with the first half-gear, rotates, releasing the second baffle from obstruction of the cement. Reversing the rotation of the handle and inserting its bottom into a limiting hole controls the amount of cement fed, thus improving the quality of cement screening. Activating a motor externally connected to the control box rotates a second rotating rod, moving a connecting rod and the screen. This causes the slider to reciprocate within a groove inside the screening machine, achieving thorough screening. However, in practical use, the connection between the screen and the motor via the rotating rod is difficult to disassemble, resulting in larger particles remaining on the screen and being difficult to clean. Furthermore, the lack of a top enclosure for the screen allows larger particles to leak through the gap between the screen and the screening machine during screening, reducing screening efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a screening device for ultra-hard inorganic filling and reinforcement materials for mining, which aims to improve the problem in the prior art that when screening begins, larger slags remaining on the screen will leak out from the gap between the screen and the screening machine, reducing the efficiency of the screening operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screening device for superhard inorganic filling and reinforcement materials for mining includes a workbench and a base plate. Two support plates are fixedly connected to the top of the workbench, and the same feeding port is fixedly connected to the top of each support plate. A servo motor is fixedly connected to the left side of the top of the workbench, and a rotating block is fixedly connected to the output end of the servo motor. Shock-absorbing spring assemblies are fixedly connected to adjacent sides of the outer walls of the two support plates, and push plates are fixedly connected to adjacent sides of the two shock-absorbing spring assemblies. A connecting strip is fixedly connected to the right side of the outer wall of the right push plate, and a locking block is fixedly connected to the top right side of the connecting strip. A filter plate is slidably connected to the top of the workbench, and a surrounding plate is fixedly connected to the top of the filter plate. Limiting plates are fixedly connected to the left and right sides of the outer walls of the surrounding plate. A collection box is fixedly connected to the left side of the top of the base plate, and a metering mechanism for quantitatively dispensing materials is provided at the bottom of the feeding port.

[0007] Furthermore, the metering mechanism includes a mounting plate, the bottom of which is fixedly connected to the top right side of the workbench. A telescopic rod is fixedly connected to the left side of the mounting plate, and a connecting plate is fixedly connected to the left end of the telescopic rod. An upper baffle is fixedly connected to the upper left side of the connecting plate, and a lower baffle is fixedly connected to the lower left side of the outer wall of the connecting plate. Both the upper and lower baffles have grooves on their outer walls, and the same metering cylinder is fixedly connected to adjacent sides of the outer walls of the two support plates.

[0008] Furthermore, the quantitative mechanism also includes multiple reinforcing plates, the right side of the outer wall of each of the multiple reinforcing plates being fixedly connected to the left side of the outer wall of the mounting plate, and the outer wall of the mounting plate having multiple weight-reducing holes.

[0009] Furthermore, multiple pulleys are fixedly connected to the bottom front and rear sides of the filter plate, and slide rails are provided on the top front and rear sides of the workbench.

[0010] Furthermore, the outer wall of the enclosure is rotatably connected to both the front and rear sides with lifting rings, and the outer wall of the collection box is fixedly connected to the front side with a handle.

[0011] Furthermore, support legs are fixedly connected to the four corners of the bottom of the workbench, and anti-slip pads are fixedly connected to the four corners of the bottom of the base plate.

[0012] Furthermore, the bottoms of all the anti-slip pads are treated with anti-slip material, and the outer walls of the two support plates each have two grooves.

[0013] Compared with the prior art, this utility model uses a servo motor to drive the rotating block to rotate. With the engagement of the locking block and the inner wall of the rotating block and the transmission of the connecting strip, the push plate can make a reciprocating motion of left and right translation, thereby realizing efficient vibration screening of the filter plate. The waste residue left on the filter plate can be poured out by pulling out the filter plate, which improves the working efficiency. At the same time, the surrounding plate prevents the material residue from leaking and affecting the screening effect. By setting a damping spring group to connect the support plate and the push plate, the vibration can be effectively buffered when the push plate moves, reducing the impact on the support plate and the worktable, thereby extending the service life of the equipment.

[0014] In addition, this utility model uses the telescopic rod to drive the connecting plate, upper baffle and lower baffle to slide in the plate groove, so that the grooves of the upper baffle and lower baffle are alternately aligned with the opening of the metering cylinder, realizing the precise quantitative storage and dispensing of materials, realizing the automated accurate measurement and stable dispensing of materials, improving the working efficiency and reliability of the screening device, and reducing the cost of manual operation and the risk of error.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] See attached document Figure 2 Appendix Figure 3 and attached Figure 4This embodiment exemplarily demonstrates a screening device for mining superhard inorganic filling and reinforcement materials, including a workbench 1 and a base plate 14. The workbench 1 provides a basic support platform for the entire device, and the base plate 14 supports a collection box 15, ensuring the stable placement of the collection box 15. Two support plates 3 are fixedly connected to the top of the workbench 1, serving to support the feeding port 4 and ensuring the stable setting of the feeding port 4. The top of both support plates 3 is fixedly connected to the same feeding port 4, serving as the material input channel for facilitating the feeding of mining superhard inorganic filling and reinforcement materials into the device. A servo motor is fixedly connected to the top left side of the workbench 1. Machine 5, as a power source, provides driving power for the screening process. A rotating block 6 is fixedly connected to the output end of the servo motor 5 to convert the rotational motion of the servo motor 5 into the linear motion of the clamping block 7. Shock-absorbing spring groups 9 are fixedly connected to adjacent sides of the outer walls of the two support plates 3 to buffer the impact force generated when the push plate 10 moves, reducing the impact of vibration on the overall structure of the device. Push plates 10 are fixedly connected to adjacent sides of the two shock-absorbing spring groups 9 to push the filter plate 11 in reciprocating motion, thus achieving material screening. A connecting strip 8 is fixedly connected to the right side of the outer wall of the right push plate 10 to connect the right push plate 10. 0 and 7 are connected to the top right of the connecting bar 8, which is fixedly connected to the locking block 7 and slides with the inner wall of the rotating block 6 to convert the rotational motion of the rotating block 6 into linear reciprocating motion. The locking block 7 is slidably connected to the inner wall of the rotating block 6 to realize the conversion of motion mode and drive the push plate 10 to move. The top of the worktable 1 is slidably connected to the filter plate 11, which is the main component for material screening. It achieves particle size separation of materials through vibration. The top of the filter plate 11 is fixedly connected to the surrounding plate 12 to prevent material from overflowing during screening and to ensure the smooth progress of screening. Limiting plates 1 are fixedly connected to the left and right sides of the outer wall of the surrounding plate 12. 3. To limit the movement range of the filter plate 11 and ensure the stability of the movement of the filter plate 11, a collection box 15 is fixedly connected to the top left side of the bottom plate 14 for collecting the waste residue after screening for convenient subsequent processing. Multiple pulleys 16 are fixedly connected to the bottom front and rear sides of the filter plate 11, which cooperate with the slide rails 17 on the workbench 1 to reduce the friction when the filter plate 11 slides and improve the screening efficiency. The top front and rear sides of the workbench 1 are provided with slide rails 17 to provide sliding tracks for the pulleys 16 and ensure the smooth sliding of the filter plate 11. A quantitative mechanism 2 is provided at the bottom of the feeding port 4. The quantitative mechanism 2 is used to quantitatively feed the material.

[0024] Specifically, the servo motor 5 drives the rotating block 6 to rotate, while the locking block 7 is engaged in the inner wall of the rotating block 6. As the rotating block 6 rotates, the locking block 7 performs a reciprocating motion of left and right translation, thereby driving the left push plate 10 to perform a reciprocating motion. The tops of both push plates 10 are engaged in the limiting plate 13. The reciprocating movement of the left push plate 10 drives the filter plate 11, the surrounding plate 12, the limiting plate 13, and the left push plate 10 to move synchronously, thereby achieving the screening effect. During this process, the pulley 16 follows the filter plate 11 and rolls in the slide rail 17, reducing the friction between the filter plate 11 and the worktable 1. After screening is completed, the waste residue in the filter plate 11 needs to be poured out, and the surrounding plate 12 needs to be lifted upward. At this time, the push plate 10 is disengaged from the limiting plate 13, and then the waste residue on the filter plate 11 can be poured out.

[0025] See attached document Figure 2 Appendix Figure 4 and attached Figure 5 The metering mechanism 2 includes a mounting plate 201, the bottom of which is fixedly connected to the top right side of the workbench 1. A telescopic rod 202 is fixedly connected to the left side of the mounting plate 201, which drives the connecting plate 203, the upper baffle 204, and the lower baffle 205 to move, thereby achieving automated control of the metering process. The left end of the telescopic rod 202 is fixedly connected to the connecting plate 203, which connects the telescopic rod 202 with the upper baffle 204 and the lower baffle 205, facilitating the transmission of the movement of the telescopic rod 202. The upper baffle 204 is fixedly connected to the upper left side of the connecting plate 203, which controls the process of material entering the metering cylinder 207 by cooperating with the opening at the top of the metering cylinder 207. The lower baffle 205 is fixedly connected to the lower left side of the outer wall of the connecting plate 203, which controls the process of material being dispensed from the metering cylinder 207 by cooperating with the opening at the bottom of the metering cylinder 207. The outer walls of the upper baffle 204 and the lower baffle 205 are both provided with grooves 206 to limit the flow of material. The metering mechanism 2 achieves quantitative control of materials by controlling the quantity and throughput. The same metering cylinder 207 is fixedly connected to the adjacent side of the outer wall of the two support plates 3, serving as a container for quantitative storage of the material. It stores the metered mining superhard inorganic filling and reinforcing material. The metering mechanism 2 also includes multiple reinforcing plates 208, the right side of which is fixedly connected to the left side of the outer wall of the mounting plate 201 to enhance the structural strength of the mounting plate 201 and improve the stability of the metering mechanism 2 during operation. The outer wall of the mounting plate 201 is provided with multiple weight-reducing holes 209 to reduce the overall weight of the metering mechanism 2 without affecting the structural strength and reduce operating energy consumption. The outer walls of the two support plates 3 are provided with two plate grooves 22 to provide sliding tracks for the upper baffle 204 and the lower baffle 205, ensuring the smoothness and accuracy of the baffle sliding process. The outer diameter of the plate groove 22 is consistent with the outer diameter of the two baffles, ensuring the sealing and stability of the upper baffle 204 and the lower baffle 205 when sliding in the plate groove 22, and preventing material leakage.

[0026] Specifically, in the initial state, the telescopic rod 202 is in a retracted state. At this time, the groove 206 on the upper baffle 204 is aligned with the opening at the top of the metering cylinder 207, while the lower baffle 205 blocks the opening at the bottom of the metering cylinder 207. After the material is fed into the feeding port 4, it enters the metering cylinder 207 through the groove 206 on the connecting plate 203. Then, the telescopic rod 202 extends, and the upper baffle 204 and the lower baffle 205 on the connecting plate 203 slide to the left on the plate groove 22 on the support plate 3. At this time, the upper baffle 204 blocks the opening at the top of the metering cylinder 207, and the groove 206 on the lower baffle 205 is aligned with the opening at the bottom of the metering cylinder 207. The material falls from the metering cylinder 207 into the filter plate 11.

[0027] See attached document Figure 1 Appendix Figure 2 and attached Figure 4 The outer walls of the enclosure 12 are rotatably connected to lifting rings 18 on both the front and rear sides, making it easy for operators to lift the enclosure 12 and clean the waste residue on the filter plate 11, thus improving the convenience of equipment maintenance. The outer walls of the collection box 15 are fixedly connected to the front side of the collection box, making it easy for operators to move the collection box 15 and to centrally process the collected waste residue. The bottom of the workbench 1 is fixedly connected to the four corners of the bottom of the workbench 1, which is used to support the workbench 1 and keep the screening device at a stable height above the ground, avoiding the bottom from getting damp or affected by ground debris. The bottom of the bottom of the base plate 14 is fixedly connected to the four corners of the bottom of the base plate 14. The bottom of the multiple anti-slip pads 21 are all treated with anti-slip treatment to enhance the friction between the base plate 14 and the ground, prevent the device from shifting during operation, improve the overall stability of the device, and ensure that the device can be placed stably in various ground environments.

[0028] Specifically, the lifting ring 18 on the outer wall of the enclosure 12 and the handle 19 of the collection box 15 are designed to facilitate the cleaning of waste residue and the handling of the collection box 15 by operators, thereby improving the efficiency of equipment maintenance and waste residue treatment. The support legs 20 at the bottom of the workbench 1 keep the device at a stable height off the ground, avoid moisture and debris interference at the bottom, and extend the service life of the equipment. The anti-slip pads 21 at the bottom of the base plate 14 are treated with anti-slip material to enhance the friction with the ground, ensure that the device is stable and does not shift during operation, adapt to various ground environments, and improve the overall operational stability. The electrical connection between the controller 23 and the servo motor 5 and the telescopic rod 202 realizes the automation of the screening and quantitative process, ensures the accuracy of material screening and quantitative feeding, reduces manual intervention, and improves production efficiency.

[0029] As a typical implementation of this embodiment: When the screening device is working, the mining superhard inorganic filling and reinforcing material enters from the feeding port 4 fixed to the top of the two support plates 3 and falls onto the filter plate 11 on the top of the workbench 1. The servo motor 5 located on the left side of the top of the workbench 1 is started, and the rotating block 6 connected to its output end rotates accordingly. Since the locking block 7 is engaged in the inner wall of the rotating block 6, during the rotation of the rotating block 6, the locking block 7 drives the right push plate 10 to perform a reciprocating motion of left and right translation through the connecting strip 8. At the same time, the right push plate 10 pushes the left push plate 10 to move synchronously. The tops of the two push plates 10 are engaged in the limiting plates 13 fixed on the left and right sides of the outer wall of the enclosure 12. Therefore, the reciprocating movement of the left push plate 10 will drive the filter plate 11, the enclosure 12, and the limiting plate 13 to move synchronously, causing the filter plate 11 to vibrate and realize the screening of the material. During this process, the bottom of the filter plate 11 moves back and forth. Multiple side-fixed pulleys 16 roll in the slide rails 17 opened on the front and rear sides of the top of the workbench 1, which greatly reduces the friction between the filter plate 11 and the workbench 1, ensuring the smooth progress of the screening process and reducing equipment wear. During the screening process, the material that meets the screen hole specifications passes through the filter plate 11 and falls into the collection box 15 fixed on the top left side of the bottom plate 14, while the waste residue remains on the filter plate 11. With vibration, the waste residue gradually moves to one side of the filter plate 11. When the screening is completed, the surrounding plate 12 is lifted up so that the push plate 10 is freed from the constraint of the limiting plate 13. Then the filter plate 11 can be pulled out along the slide rail 17 and the waste residue on the filter plate 11 can be poured out. In addition, the damping spring group 9 fixed on the adjacent side of the outer wall of the two support plates 3 plays a buffering role when the push plate 10 moves, reducing the impact of vibration on the support plate 3 and the workbench 1, extending the service life of the equipment, and reducing working noise.

[0030] Furthermore, before the screening operation begins, the quantitative mechanism 2 needs to accurately measure and feed the material. In the initial state, the telescopic rod 202 is in the retracted state. At this time, the groove 206 on the upper baffle 204 is aligned with the top opening of the quantitative cylinder 207 fixed on the adjacent side of the outer wall of the two support plates 3, while the lower baffle 205 tightly covers the bottom opening of the quantitative cylinder 207. When the material is fed from the feeding port 4, the material flows into the quantitative cylinder 207 through the groove 206 of the upper baffle 204, and the quantitative storage process begins. As the material in the quantitative cylinder 207 gradually accumulates, when the preset quantitative value is reached, the telescopic rod 202 extends to the left and pushes the connecting plate 203, so that the upper baffle 204 and the lower baffle 205, which are fixedly connected to the connecting plate 203, slide synchronously along the plate groove 22 on the outer wall of the support plate 3. During this process, the upper baffle 204 gradually covers the quantitative cylinder 207. The top opening of the metering cylinder 207 blocks the continued flow of material. At the same time, the groove 206 on the lower baffle 205 is aligned with the bottom opening of the metering cylinder 207, creating a channel for material feeding. Subsequently, the metered material in the metering cylinder 207 falls evenly through the groove 206 of the lower baffle 205 onto the filter plate 11 on the top of the workbench 1, completing the metering process. At this time, the telescopic rod 202 remains extended to ensure that all the material in the metering cylinder 207 is fed out. The mounting plate 201 serves as the load-bearing component of the metering mechanism 2, and its bottom is fixedly connected to the workbench 1. The reinforcing plate 208 enhances the structural rigidity of the mounting plate 201 and the workbench 1, ensuring the stability of the mounting plate 201 when the telescopic rod 202 extends and retracts. Meanwhile, the weight-reducing hole 209 on the mounting plate 201 reduces the overall weight of the metering mechanism 2 without weakening the structural strength.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
