[0032] 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.
[0033] Please see Figures 1-9This utility model proposes a mineral screening device for mineral exploration, including a shell 1. A guide rail 11 and a support plate 12 are fixedly connected to the inner wall of the shell 1. The support plate 12 is used to support the frame 51. A feeding hopper 3 is provided at the upper end of the shell 1, and a collection box 6 is provided at the lower end of the shell 1. A hinge plate 2 is hinged to the shell 1. A limit rod is rotatably connected to the outer wall of the shell 1 to limit the hinge plate 2. A screening mechanism is provided inside the shell 1, and a feeding plate 4 is provided below the screening mechanism.
[0034] In this embodiment of the utility model, in order to enable quick replacement of the screen 52, the screening mechanism specifically includes a frame 51, with a roller 511 rotatably connected to the outer wall of the frame 51. The roller 511 is rotatably connected to the guide rail 11, which facilitates the removal of the frame 51 from the housing 1. The guide rail 11 is composed of two horizontal plates, which can limit the frame 51 and prevent it from jumping up and down when the hammer 14 strikes. A positioning rod 512 is fixedly connected to the outer wall of the frame 51. A limiting groove 513 is provided in the frame 51. A positioning hole is provided on the screen 52. The middle of the screen 52 is designed with a slope, and the end of the screen 52 is designed with a flat surface. A locking block 56 passes through the frame 51 and is slidably connected to the frame 51. A crossbar 54 is fixedly connected to the end of the locking block 56. The crossbar 54 is elastically connected to the inner wall of the frame 51 through a spring 55. A rotating rod 57 is rotatably connected to the crossbar 54. The cover 53 is fixed to the outer wall of the frame 51 by screws.
[0035] Furthermore, an L-shaped rod 13 is hinged to the outer wall of the guide rail 11. A hammer head 14 is fixedly connected to one end of the L-shaped rod 13, and a through groove 16 is opened at the other end of the L-shaped rod 13. A rod body 15 is slidably connected to the through groove 16. The rod body 15 is penetrated by a T-shaped rod 17 and is fixedly connected to the T-shaped rod 17. The T-shaped rod 17 penetrates the housing 1 and is slidably connected to the housing 1. A sliding groove 171 is opened at the upper end of the T-shaped rod 17. A motor 19 is fixedly connected to the outer wall of the housing 1. A disc 18 is fixedly connected to the output end of the motor 19. A protrusion 181 is fixedly connected to the outer wall of the disc 18. The protrusion 181 is a distance away from the center of the disc. By rotating the protrusion 181, the T-shaped rod 17 can move up and down reciprocally. The protrusion 181 is slidably connected to the sliding groove 171.
[0036] When the motor 19 starts, the disc 18, which is fixedly connected to the output end of the motor 19, drives the protrusion 181 to rotate. At this time, the protrusion 181 will apply a force to the slide groove 171, causing the T-shaped rod 17 to drive the rod body 15 to move up and down reciprocally. At this time, the rod body 15 will apply a force to the L-shaped rod 13, causing the L-shaped rod 13 to swing back and forth around the hinge point. During this process, the hammer head 14 will periodically strike the outer wall of the screen 52, thereby causing the screen 52 to vibrate, thus improving the screening effect of the screen 52.
[0037] In this invention, during use, the ore is first poured into the outer wall of the screen 52 through the hopper 3. Then, the motor 19 is started, causing the hammer 14 to strike the outer wall of the screen 52. At this time, the smaller ore pieces after screening will fall into the collection box 6, while the larger ore pieces will be discharged outward through the discharge plate 4. When the screen 52 needs to be cleaned or replaced, simply open the hinge plate 2, pull the frame 51 out of the housing 1, and then pull the rotating rod 57 so that the crossbar 54... The movement of the locking block 56 causes the locking block 56 to disengage from the screen 52. Then, the rotating rod 57 is rotated 90 degrees, causing the rotating rod 57 to lock onto the outer wall of the frame 51. The screen 52 can then be removed from the frame 51. When installing the screen 52, simply insert the positioning hole on the screen 52 into the positioning rod 512, and then rotate the rotating rod 57 back to its original position. At this time, the crossbar 54 will be driven by the spring 55 to return the locking block 56 to its original position, thereby fixing the screen 52.
[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
