Abstract
Description
Technical Field
[0001] This utility model relates to the field of ore mining technology, and in particular to a soil-rock separation device. Background Technology
[0002] In mining operations, excavators are used to excavate designated areas. During excavation, soil and ore are easily mixed. Since the core objective of mining is to obtain economically valuable mineral-bearing materials, the soil-rock mixture needs to undergo a soil-rock separation process to effectively separate the soil from the mineral-bearing rocks. Among existing technologies for soil-rock separation in mining, vibrating screens are one of the most widely used core pieces of equipment. Through high-frequency vibration, they can break down the bond between soil and ore, allowing the soil to fall through the screen holes and separate from the ore.
[0003] In related technologies, during the screening of ore and soil using vibrating screens, soil particles separate from the ore, and the ore rollers press against the soil particles, leading to soil particle blockage of the screen holes. This not only makes it difficult to effectively separate the soil from the ore but also significantly affects the ore screening effect. This blockage prolongs the screening time and reduces the screening quality. Furthermore, moist soil easily adheres to the screen mesh, further hindering the ore screening and increasing the difficulty of the screening operation. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the related art.
[0005] Therefore, the purpose of this utility model is to propose a soil-rock separation device. Through the cooperation of the drive component and the guide component, the eccentric wheel can fully cover the screen, effectively preventing soil from adhering to or clogging the screen, and significantly improving the efficiency and quality of soil-rock separation.
[0006] To achieve the above objectives, this utility model proposes a soil-rock separation device, comprising a frame, a screen, a vibration mechanism, and a separation mechanism. The screen is disposed inside the frame, the vibration mechanism is mounted on the frame, and the separation mechanism is disposed within the frame and below the screen. The separation mechanism includes a rotating shaft, eccentric wheels, a drive assembly, and a guide assembly. The eccentric wheels are equidistantly disposed on the rotating shaft, and their eccentric directions are staggered along the circumference. The drive assembly is disposed at both ends of the rotating shaft and drives the rotating shaft to move synchronously. The guide assembly is disposed at the end of the rotating shaft, and the rotating shaft is located inside the guide assembly.
[0007] In addition, the soil-rock separation device proposed above according to this utility model may also have the following additional technical features: Specifically, the guiding assembly includes two guide frames, a guide groove, a guide seat, and a guide rail. The guide rail is disposed on the guide frame, the guide seat is disposed at the end of the rotating shaft and slidably connected to the outer wall of the guide rail, the guide groove is formed inside the guide frame, and the rotating shaft is located inside the guide groove.
[0008] Specifically, the drive assembly includes a transmission base, a gear, a connecting plate, a rack, and a linear motor. The linear motor is mounted on the guide frame, and the slider of the linear motor is connected to the transmission base through the connecting plate. The transmission base is disposed on the rotating shaft, the rack is disposed on the guide frame, and the gear is disposed at the end of the rotating shaft and meshes with the rack.
[0009] Specifically, the vibration mechanism includes two vibrators, an elastic element, and a base. The two vibrators are symmetrically arranged on the crossbeam of the frame, and the elastic element is symmetrically arranged on both sides of the frame. The frame is mounted on the base via the elastic element.
[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This utility model generates vibration force through a vibration mechanism, which can achieve effective separation of soil and rock. Through the cooperation of the drive component and the guide component, after the linear motor is started, the slider moves in a straight line and drives the transmission seat to move synchronously through the connecting plate. At the same time, the gear rolls along the rack, thereby driving the rotating shaft to rotate, thus realizing the compound motion of the rotating shaft. When the rotating shaft generates compound motion, it drives the eccentric wheel, which can make the eccentric wheel fully cover the screen, effectively preventing soil from adhering to or clogging the screen, and significantly improving the efficiency and quality of soil and rock separation.

Detailed Implementation
[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0015] The soil-rock separation device of this utility model embodiment will be described below with reference to the accompanying drawings.
[0016] like Figures 1-6 As shown, an embodiment of the present invention provides a soil-rock separation device, comprising a frame 1, a screen 2, a vibration mechanism 3, and a separation mechanism 4, wherein... Screen 2 is installed inside frame 1; It should be noted that the mesh size of screen 2 is set according to the actual size of the soil and rock particles to be separated, so as to ensure that soil particles that meet the particle size requirements can pass through screen 2 smoothly and fall down during vibration, while the ore is trapped above screen 2, thus achieving soil and rock separation. Meanwhile, the edge of the screen 2 is connected to the frame 1 by a metal pressure plate and anti-loosening bolts to prevent the screen 2 from loosening or falling off during vibration, thus ensuring the stability and reliability of the soil and rock separation process.
[0017] The separation mechanism 4 is installed inside the frame 1 and located below the screen 2; The separation mechanism 4 includes a rotating shaft 41, eccentric wheels 42, a drive assembly 5, and a guide assembly 6; the eccentric wheels 42 are equidistantly arranged on the rotating shaft 41, and the eccentric directions of the eccentric wheels 42 are staggered along the circumference. It should be noted that the eccentric wheel 42 is made of polyurethane, which has high wear resistance and good elasticity, and can maintain a long service life in working environments with high-speed rotation and frequent impact, while reducing damage to the screen 2. The staggered distribution of the eccentric wheels 42 can prevent all the eccentric wheels 42 from hitting the screen 2 at the same time, which would cause excessive overall impact and make the excitation force distribution more uniform. The drive components 5 are located at both ends of the rotating shaft 41 and drive the rotating shaft 41 to move synchronously; It should be noted that the drive component 5 is used to drive the rotating shaft 41 to rotate, thereby driving the eccentric wheel 42 to swing periodically. During the swinging process, the eccentric wheel 42 continuously collides with the screen 2, causing the screen 2 to produce a continuous vibration effect. This vibration can effectively break the adhesion between the soil and the screen 2, causing the soil to fall through the mesh of the screen 2, thereby ensuring the separation effect of soil and ore. The guide assembly 6 is disposed at the end of the rotating shaft 41, and the rotating shaft 41 is located inside the guide assembly 6; It should be noted that the main function of the guide assembly 6 is to provide stable support and guidance for the rotating shaft 41, ensuring that the rotating shaft 41 can travel in a predetermined direction during rotation, thereby fully covering the screen 2 and separating the soil clogging the mesh and adhering to the screen 2 from the screen 2.
[0018] In one embodiment of this utility model, such as Figure 4 As shown, the guide assembly 6 includes two guide frames 61, a guide groove 62, a guide seat 63, and a guide rail 64. The guide rail 64 is disposed on the guide frame 61; the guide seat 63 is disposed at the end of the rotating shaft 41 and is slidably connected to the outer wall of the guide rail 64; the guide groove 62 is opened inside the guide frame 61; and the rotating shaft 41 is located inside the guide groove 62.
[0019] Understandably, the guide frame 61, as a support frame, can ensure that the rotating shaft 41 will not shift its position during rotation and travel, while the guide groove 62 further restricts the range of movement of the rotating shaft 41, ensuring that it can only run along the predetermined trajectory, that is, it can only move along the guide groove 62, thereby ensuring the stability and reliability of the entire separation mechanism 4. Furthermore, the guide rail 64 and guide seat 63 can further guide the travel path of the rotating shaft 41. When the rotating shaft 41 travels along the guide groove 62, the rotating shaft 41 slides along the guide rail 64 through the guide seat 63. With the cooperation of the guide groove 62, the rotating shaft 41 can move smoothly along the guide groove 62 while rotating, thereby driving the eccentric wheel 42 to periodically collide with different positions of the screen 2, ensuring that each area on the screen 2 is subjected to uniform vibration, and effectively preventing the local accumulation and blockage of soil on the screen 2.
[0020] In one embodiment of this utility model, such as Figure 4 As shown, the drive assembly 5 includes a transmission base 51, a gear 52, a connecting plate 53, a rack 54, and a linear motor 55. The linear motor 55 is mounted on the guide frame 61, and the slider of the linear motor 55 is connected to the transmission base 51 through the connecting plate 53. The transmission base 51 is disposed on the rotating shaft 41. The rack 54 is disposed on the guide frame 61. The gear 52 is disposed at the end of the rotating shaft 41 and meshes with the rack 54. It should be noted that the transmission base 51 is connected to the rotating shaft 41 through a bearing to ensure that the rotating shaft 41 can rotate smoothly. The transmission base 51 is fixedly connected to the slider of the linear motor 55 through the connecting plate 53. Specifically, after the linear motor 55 is started, its slider moves in a straight line and drives the transmission seat 51 to move synchronously through the connecting plate 53. The transmission seat 51 drives the rotating shaft 41 to move in a straight line. Meanwhile, since gear 52 is located at the end of rotating shaft 41 and meshes with rack 54, gear 52 will roll along rack 54 during the linear movement of rotating shaft 41, thereby driving rotating shaft 41 to rotate. Furthermore, in this process, linear motion and rotational motion can be combined to achieve the composite motion of the rotating shaft 41, thereby enabling the eccentric wheel 42 to cover the entire screen 2 and ensuring the cleaning effect on the screen 2. It should be noted that two sets of linear motors 55 are configured in the drive component 5. Both sets of linear motors 55 are controlled by the PLC to ensure that they can operate synchronously.
[0021] In one embodiment of this utility model, such as Figure 2 As shown, the vibration mechanism 3 is mounted on the frame 1. The vibration mechanism 3 includes two vibrators 31, elastic elements 32 and a base 33. The two vibrators 31 are symmetrically arranged on the crossbeam of the frame 1. The elastic elements 32 are symmetrically arranged on both sides of the frame 1. The frame 1 is mounted on the base 33 through the elastic elements 32. It should be noted that the elastic element 32 described in this embodiment is a high-strength spring, which provides elastic support for the frame 1, thereby enabling the frame 1 to generate continuous and stable vibration under the vibration generated by the vibrator 31. The vibrator 31 uses a vibrating motor and is controlled by a PLC. Its speed and amplitude can be adjusted according to actual needs to meet the separation requirements of soil and rock mixtures with different particle sizes and moisture content. Specifically, when the vibrator 31 is working, the generated vibration force is transmitted to the screen 2 through the frame 1, causing the soil and rock mixture on the screen 2 to be loosened by vibration. Under the dual action of vibration and gravity, the soil particles fall through the mesh of the screen 2, while the ore is trapped on the screen 2, thus achieving effective separation of soil and rock.
[0022] In summary, the soil and rock separation device of this utility model can effectively separate soil and rock by generating vibration force through the vibration mechanism. Through the cooperation of the drive component and the guide component, the composite motion of the rotating shaft can be realized. When the rotating shaft generates composite motion, it drives the eccentric wheel, which can then fully cover the screen, effectively preventing soil from adhering to or clogging the screen, and significantly improving the efficiency and quality of soil and rock separation.
