Description

Technical Field

[0001] This utility model relates to the field of crushing and screening devices, and in particular to a non-metallic mineral crushing and screening device. Background Technology

[0002] With human development and social progress, the amount of non-metallic waste discharged is increasing day by day, and non-metallic waste seriously threatens the living environment. Therefore, the market demand for non-metallic waste processing equipment has increased dramatically.

[0003] Traditional crushing equipment, such as jaw crushers and cone crushers, struggles to precisely control the particle size of crushed minerals, often resulting in an excessively wide particle size distribution. This leads to an unreasonable ratio of coarse to fine particles in the product, affecting subsequent processing and product quality. In existing crushing and screening devices, the crushing and screening equipment often operate independently, with insufficient coordination between them. This results in an unsmooth process flow, with material accumulation or insufficient supply in intermediate stages, impacting production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-metallic mineral crushing and screening device that solves the problem that the screening device cannot operate simultaneously during crushing.

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

[0006] A non-metallic mineral crushing and screening device includes a housing. A motor is installed on one outer wall of the housing. A rotating shaft is fixedly connected to the drive end of the motor. Mounting brackets are fixedly connected to the outer walls of the rotating shaft. Crushing rollers are rotatably connected inside the mounting brackets. A sprocket is fixedly connected to one end of the rotating shaft through the interior of the housing. A chain is meshed with the outer wall of the sprocket. A second sprocket is meshed with the bottom of the chain. A vibration component is installed on the outer wall of the second sprocket. Protective plates are fixedly connected to the left and right sides of the bottom of the housing.

[0007] Furthermore, the vibration assembly includes a rotating rod fixedly connected to the outer wall of the second sprocket and a rotating column rotatably connected to the inner wall of the guard plate. An eccentric plate is fixedly connected to one end of each of the rotating rod and the rotating column. A connecting rod is fixedly connected to one end of each of the two eccentric plates. A rotating plate is rotatably connected inside each of the eccentric plates.

[0008] Furthermore, a fixing plate is fixedly connected to the top of the rotating plate, and a filter screen is installed on the top of the fixing plate.

[0009] Furthermore, sliders are fixedly connected to both the left and right sides of the filter screen, and the sliders are slidably connected to the inner wall of the protective plate.

[0010] Furthermore, the bottom of the guard plate is fixedly connected to the top of the support plate, and an inclined plate is fixedly connected to the front side of the guard plate.

[0011] Furthermore, a feed inlet is fixedly connected to the top of the box, and several protrusions are installed on the inner wall of the box.

[0012] Furthermore, a collection box is fixedly connected to the bottom of the support plate, and multiple support legs are fixedly connected to the bottom of the support plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the rotating shaft is driven by a motor to rotate, and the rotating shaft drives the mounting frame to move synchronously, which in turn drives the crushing roller inside the mounting frame to rotate. This achieves powerful crushing of non-metallic minerals entering the box, breaking large minerals into smaller particles, which facilitates further processing or screening operations. This powerful crushing of non-metallic minerals helps to improve the efficiency of subsequent processing or screening, enabling the minerals to better meet diverse production needs.

[0015] 2. In this utility model, sprocket one drives the chain to rotate, the chain drives sprocket two to rotate, and sprocket two drives the rotating rod to rotate. Then the rotating rod and the eccentric plate on the rotating column rotate. The two eccentric plates drive the connecting rod to rotate, and the eccentric plates drive the rotating plate to rotate. Thus, the rotating plate cooperates with the fixed plate to drive the filter screen to move up and down, thereby screening the material, improving screening efficiency, and allowing qualified and unqualified materials to be separated quickly and accurately.

[0023] 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.

[0024] Reference Figure 1 - Figure 3 An embodiment of this utility model provides a non-metallic mineral crushing and screening device, comprising a housing 1, a motor 3 installed on one outer wall of the housing 1, a rotating shaft 4 fixedly connected to the drive end of the motor 3, a mounting frame 5 fixedly connected to the outer wall of the rotating shaft 4, a crushing roller 6 rotatably connected inside the mounting frame 5, a sprocket 7 fixedly connected to one end of the rotating shaft 4 through the interior of the housing 1, a chain 8 meshing with the outer wall of the sprocket 7, a sprocket 9 meshing with the bottom of the chain 8, a vibration component installed on the outer wall of the sprocket 9, protective plates 18 fixedly connected to the left and right sides of the bottom of the housing 1, the bottom of the protective plates 18 fixedly connected to the top of the support plate 19, an inclined plate 20 fixedly connected to the front side of the protective plates 18, a feed inlet 2 fixedly connected to the top of the housing 1, several protrusions 23 installed on the inner wall of the housing 1, a collection box 21 fixedly connected to the bottom of the support plate 19, and multiple support legs 22 fixedly connected to the bottom of the support plate 19.

[0025] Specifically, firstly, the motor 3 is securely mounted on one side of the outer wall of the housing 1, and its drive end is firmly fixed to the rotating shaft 4 to ensure stable power transmission. The rotating shaft 4 extends horizontally through one side wall of the housing 1, and mounting brackets 5 are evenly distributed on its outer wall. The mounting brackets 5 adopt a reasonable structural design, which allows the crushing roller 6 to rotate smoothly inside it through connecting parts such as shaft pins. When the rotating shaft 4 rotates, it drives the mounting brackets 5 to move synchronously, thereby causing the crushing roller 6 to rotate at high speed and powerfully crush the non-metallic minerals entering the housing 1. After penetrating the inside of the housing 1, one end of the rotating shaft 4 is precisely fixedly connected to the sprocket 7. The sprocket 7 and the chain 8 mesh very tightly, and the chain 8 can run smoothly under its drive without skipping teeth or derailing. The bottom of chain 8 is tightly meshed with sprocket 9, which has a rigid connection with the vibration assembly, such as a key connection, to ensure that the rotation of sprocket 9 can precisely drive the vibration assembly, making the screening process more efficient. The left and right side guard plates 18 at the bottom of the box 1 are vertically fixed to the top of the support plate 19. The two can be connected by welding or high-strength bolts to ensure the stability of the bottom structure of the entire device. The inclined plate 20 on the front side of the guard plate 18 is integrally formed with the guard plate 18 or is fixed by strong welding, which facilitates the sliding of crushed and screened materials. The feed port 2 at the top of the box 1 is vertically upward and is connected to the box 1 by flange or welded and sealed to ensure that there is no material leakage during the feeding process. Several protrusions 23 are fixedly connected to the inner wall of the housing 1. The surface of the protrusions 23 is in contact with the outer surface of the crushing roller 6, which can effectively prevent the material from falling too fast, increase the residence time of the material in the crushing area, and improve the crushing effect. The collection box 21 at the bottom of the support plate 19 is fixed by means of slots, buckles or bolts, which is convenient for disassembly and cleaning. The qualified material after being screened by the filter screen 16 will fall into the inside of the collection box 21, while the unqualified material will fall into the outside through the inclined plate 20 for secondary crushing and screening. Multiple support legs 22 are evenly distributed at the bottom of the support plate 19 and welded to the support plate 19 to provide solid support for the entire device, ensure its stability during operation, and achieve leakage prevention of feeding, smooth material sliding, and sufficient crushing.

[0026] Reference Figure 4 and Figure 5 The vibration assembly includes a rotating rod 10 fixedly connected to the outer wall of the sprocket 2 9 and a rotating column 12 rotatably connected to the inner wall of the guard plate 18. An eccentric plate 11 is fixedly connected to one end of the rotating rod 10 and the rotating column 12. A connecting rod 13 is fixedly connected to one end of the two eccentric plates 11. A rotating plate 14 is rotatably connected inside the eccentric plates 11. A fixed plate 15 is fixedly connected to the top of the rotating plate 14. A filter screen 16 is installed on the top of the fixed plate 15. Slider blocks 17 are fixedly connected to both sides of the filter screen 16. The sliders 17 are slidably connected to the inner wall of the guard plate 18.

[0027] Specifically, the outer wall of the second sprocket 9 is fixed to one end of the rotating rod 10 by welding or keying, making the two a whole. This ensures that the second sprocket 9 can drive the rotating rod 10 to rotate synchronously when it rotates. The other end of the rotating rod 10 is fixed to one end of the eccentric plate 11 by welding, so that the eccentric plate 11 can move eccentrically with the rotation of the rotating rod 10. The rotating column 12 is rotatably connected to the inner wall of the guard plate 18 through a bearing. This connection method can ensure that the rotating column 12 can rotate flexibly in the guard plate 18 and also provide support for it. The other end of the rotating column 12 is also welded to one end of the eccentric plate 11, working together with the rotating rod 10 to make the movement of the eccentric plate 11 more stable and regular. The opposite ends of the two eccentric plates 11 are fixedly connected to the connecting rod 13 by welding or bolting. The function of the connecting rod 13 is to maintain the synchronicity of the movement of the two eccentric plates 11, so that they can perform eccentric movements in a coordinated manner during rotation, thereby providing stable power for subsequent vibration. Inside the eccentric plate 11, the rotating plate 14 is rotatably connected to the eccentric plate 11 through connecting parts such as shaft pins. The shaft pins allow the rotating plate 14 to rotate flexibly under the drive of the eccentric plate 11, thereby converting the eccentric movement of the eccentric plate 11 into the up-and-down swing of the rotating plate 14. The top of the rotating plate 14 is connected to the fixed plate. 15 is fixedly connected by welding or bolts to ensure a firm and reliable connection between the two, so that the rotating plate 14 can stably drive the fixed plate 15 to move together. The top of the fixed plate 15 and the filter screen 16 can be installed by screw fixing or snap-fit, so that the filter screen 16 can be stably placed on the fixed plate 15 for screening materials during vibration. Slider 17 is fixedly connected to both sides of the filter screen 16. The slider 17 is slidably connected to the inner wall of the guard plate 18 through a sliding groove. This connection method can not only restrict the movement direction of the filter screen 16, so that it can only vibrate up and down in the vertical direction, but also reduce the friction between the filter screen 16 and the guard plate 18, ensuring the smoothness of the vibration process. While restricting the vibration direction, it also reduces friction, ensuring efficient and stable material screening.

[0028] Working principle: By starting the motor 3, the power of the motor 3 is stably transmitted to the rotating shaft 4. The rotating shaft 4 passes through the side wall of the box 1. The mounting bracket 5 on the rotating shaft 4 drives the crushing roller 6 to rotate, which powerfully crushes the non-metallic minerals entering the box 1. The protrusions 23 on the inner wall of the box 1 fit against the outer surface of the crushing roller 6, preventing the material from falling too quickly and increasing the residence time of the material in the crushing zone, thereby improving the crushing effect. One end of the rotating shaft 4 is fixedly connected to the first sprocket 7, which is tightly meshed with the chain 8. The chain 8 is in turn meshed with the second sprocket 9, transmitting the rotation of the rotating shaft 4 to the second sprocket 9. Wheel 2 9 is rigidly connected to the vibration assembly, driving the rotating rod 10 to rotate. The rotating rod 10 drives the eccentric plate 11 to perform eccentric motion. The rotating column 12 is rotatably connected to the inner wall of the guard plate 18, and its other end is welded to the eccentric plate 11. Together with the rotating rod 10, it makes the movement of the eccentric plate 11 more stable and regular. The two eccentric plates 11 maintain the synchronization of movement through the connecting rod 13, providing stable power for vibration. The eccentric plate 11 drives the rotating plate 14 to swing up and down. The rotating plate 14 drives the fixed plate 15 to move. The filter screen 16 on the fixed plate 15 vibrates accordingly, screening the crushed material.
