Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and more specifically, to a mineral sample processing device. Background Technology

[0002] Mineral sample preparation is a crucial step in geological exploration, mineral processing, and quality control. Its core purpose is to transform the collected raw bulk samples into representative analytical samples with particle sizes that meet the requirements of laboratory analysis through steps such as crushing, sieving, reduction, and grinding.

[0003] A search revealed that the invention patent with publication number CN114950671A discloses a sample crushing device for geological and mineral exploration, which includes a body, a feeding hopper fixedly installed on the upper surface of the body, a roller rotatably connected to the outer surface of the feeding hopper, a groove opened on the side adjacent to the roller rotatably installed on the feeding hopper, a compression spring fixedly installed on the surface of the groove, and a crossbar fixedly installed on the other end of the compression spring.

[0004] Currently, the crushing process for mineral samples typically uses jaw crushers, roll crushers, or disc crushers for coarse and medium crushing. The crushed material is then transferred to separate screening equipment such as vibrating screens or rotary vibrating screens for grading. This results in mineral sample crushing and screening usually being handled as two independent processes, which is cumbersome. Furthermore, the screens of these screening equipment are prone to clogging, significantly reducing screening efficiency and processing capacity. Therefore, improvements are needed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a solution that overcomes or at least partially solves the above technical problems.

[0006] This utility model provides a mineral sample processing device, including a processing bin. A crushing recess is fixedly connected to the inner side of the upper opening of the processing bin. Multiple supports are welded to the top of the processing bin, and a top seat is fixedly connected to the top of the multiple supports. A hydraulic cylinder is fixedly installed in the middle of the upper end of the top seat. The telescopic shaft of the hydraulic cylinder passes through the top seat and is slidably connected to the top seat. A convex connecting shaft is fixedly connected to the end of the telescopic shaft. A crushing protrusion is rotatably connected to the outer side of the convex connecting shaft. The position of the crushing protrusion corresponds to the position of the crushing recess. Multiple fixing rods are fixedly connected to the lower inner side of the processing bin. A support base is fixedly connected to the end of the multiple fixing rods. A motor is fixedly installed in the middle of the upper end of the support base. A square shaft is fixedly connected to the end of the output shaft of the motor. A bushing is slidably connected to the outer side of the square shaft. The top of the bushing is fixedly connected to the bottom of the crushing protrusion. A screening cone is fixedly connected to the middle of the outer side of the bushing. The screening cone is slidably connected to the inside of the processing bin.

[0007] In a preferred embodiment, a ball bearing is embedded in the shaft of the convex connecting shaft, and the ball bearing contacts the inner surface of the crushing convex seat.

[0008] In a preferred embodiment, the bushing is shaped like a circle on the outside and a square on the inside, and the bushing is made of steel.

[0009] In a preferred embodiment, a protective cover is fixedly connected to the lower outer side of the bushing, and the position of the protective cover corresponds to the position of the motor.

[0010] In a preferred embodiment, the side wall of the processing hopper has two symmetrically arranged coarse material outlets, the positions of which correspond to the positions of the screening cone.

[0011] In a preferred embodiment, a slide rod is slidably connected to the bottom of the crushing recess, and a baffle bar is fixedly connected to the bottom of the slide rod, the baffle bar abutting against the inclined surface of the screening cone.

[0012] In a preferred embodiment, a spring is provided inside the crushing recess, with one end of the spring fixedly connected to the top of a slide rod and the other end of the spring fixedly connected to the inner surface of the crushing recess.

[0013] In a preferred embodiment, a plurality of support legs are fixedly connected to the upper outer side of the processing hopper, and the plurality of support legs are arranged in a ring array along the circumference of the processing hopper.

[0014] The targeted solution provided by this utility model has the following beneficial effects: 1. This solution efficiently integrates crushing and screening functions into one unit. The motor drives the crushing cam and screening cone to rotate synchronously through the square shaft and bushing, realizing dynamic crushing and centrifugal screening. The crushed material falls directly onto the rotating screening cone. Qualified fine material is quickly discharged through the cone gap under the action of centrifugal force, while coarse material slides along the cone surface to the periphery and is collected from the coarse material outlet, effectively improving processing efficiency and reducing manual intervention and labor intensity.

[0015] 2. This solution features a movable baffle at the bottom of the crushing recess, which closely contacts the screening cone. The relative movement between the two continuously scrapes away particles clogging the sieve holes, ensuring smooth screening. Simultaneously, a hydraulic cylinder drives the entire crushing boss and screening cone bushing assembly to slide up and down along the square shaft. This not only allows for flexible adjustment of the gap between the crushing boss and the recess to control the output particle size, but also utilizes the lifting and lowering of the crushing boss to hammer the sample, improving crushing efficiency and preventing jamming.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This utility model provides a technical solution: a mineral sample processing device, including a processing bin 1, a crushing recess 2 fixedly connected to the inner side of the upper opening of the processing bin 1, multiple supports 3 welded to the top of the processing bin 1, a top seat 4 fixedly connected to the top of the multiple supports 3, a hydraulic cylinder 5 fixedly installed in the middle of the upper end of the top seat 4, the telescopic shaft of the hydraulic cylinder 5 passing through the top seat 4 and slidably connected to the top seat 4, a convex connecting shaft 6 fixedly connected to the end of the telescopic shaft, a crushing protrusion 7 rotatably connected to the outer side of the shaft of the convex connecting shaft 6, the position of the crushing protrusion 7 corresponding to the position of the crushing recess 2, a ball bearing 601 embedded in the shaft of the convex connecting shaft 6, and the ball bearing 601 contacting the inner surface of the crushing protrusion 7. The upper end of the crushing protrusion 7 is provided with a convex groove to accommodate the convex connecting shaft 6. The relative friction between the two is reduced by the inclusion of ball bearings 601. A gap is left between the crushing protrusion 7 and the crushing recess 2 for sample crushing. Both the inclined surfaces of the crushing protrusion 7 and the crushing recess 2 are welded with protrusions. The engagement of these protrusions during relative rotation further enhances the crushing capacity of the crushing protrusion 7 and the crushing recess 2 for mineral samples. Multiple support legs 16 are fixedly connected to the upper outer side of the processing hopper 1, and these support legs 16 are arranged in a circular array along the circumference of the processing hopper 1. The overall height of the support legs 16 is higher than that of the processing hopper 1, which allows the processing hopper 1 to be lifted off the ground, suspending the bottom of the processing hopper 1 and facilitating the discharge of fine materials after screening.

[0021] Reference Figure 2 Multiple fixing rods 8 are fixedly connected to the lower inner side of the processing hopper 1. The ends of the fixing rods 8 are all fixedly connected to a support base 801. A motor 9 is fixedly installed at the upper center of the support base 801. A square shaft 10 is fixedly connected to the end of the output shaft of the motor 9. A bushing 11 is slidably connected to the outer side of the square shaft 10. The bushing 11 is round on the outside and square on the inside, and is made of steel. By setting the bushing 11 to be round on the outside and square on the inside, it can cooperate with the square shaft 10, allowing it to not only rotate via the motor 9 but also move axially up and down via the hydraulic cylinder 5. A protective cover 17 is fixedly connected to the lower outer side of the bushing 11, and the position of the protective cover 17 corresponds to the position of the motor 9. The protective cover 17 is generally conical in shape and is used to protect the motor 9, preventing the crushed sample from impacting the motor 9.

[0022] Reference Figure 1 , Figure 2 , Figure 3The top of the bushing 11 is fixedly connected to the bottom of the crushing protrusion 7. A screening cone 12 is fixedly connected to the middle of the outer side of the bushing 11. The screening cone 12 is slidably connected to the inside of the processing hopper 1. Two symmetrically arranged coarse material outlets 101 are opened on the side wall of the processing hopper 1, and the positions of the coarse material outlets 101 correspond to the positions of the screening cone 12. The coarse material outlets 101 are used to discharge the coarse material samples filtered by the screening cone 12. A slide rod 13 is slidably connected to the bottom of the crushing recess 2. A baffle strip 14 is fixedly connected to the bottom of the slide rod 13. The baffle strip 14 abuts against the inclined surface of the screening cone 12. A spring 15 is installed inside the crushing recess 2. One end of the spring 15 is fixedly connected to the top of the slide rod 13, and the other end of the spring 15 is fixedly connected to the inner surface of the crushing recess 2. The spring 15 can act on the baffle strip 14 to keep it in contact with the screening cone 12. By setting the baffle bar 14, it can continuously scrape the disc surface, pushing back or scraping away the particles stuck in the screen holes, ensuring that the screening process is continuous and efficient.

[0023] Operating Procedure: During operation, the mineral sample to be processed is fed into the upper opening of the processing hopper 1. The material falls into the gap between the crushing protrusion 7 and the crushing recess 2. Simultaneously, the motor 9 is started. The motor 9 drives the crushing protrusion 7 and the screening cone 12 to rotate together via the square shaft 10 and the bushing 11. Meanwhile, the hydraulic cylinder 5 pushes the convex connecting shaft 6 and the crushing protrusion 7 downwards, applying a huge compressive force to the material in the gap. At the same time, the crushing protrusion 7 rotates relative to the fixed crushing recess 2, and the protrusions on it bite, shear, and grind the material. The initially crushed material falls downwards into the rotating... On the rotating screening cone 12, under the action of centrifugal force, the material moves outward along the inclined surface of the screening cone 12. During this process, qualified fine materials smaller than the screen hole size quickly pass through the screen holes and fall into the bottom of the processing bin 1, and are finally discharged and collected from the suspended bottom of the bin. Large particles that fail to pass through the screen holes are thrown to the edge of the screening cone 12 under the action of centrifugal force and discharged through the coarse material outlet 101 on the side wall of the bin. In addition, the baffle strip 14 close to the surface of the screening cone 12 continuously scrapes the disk surface under the action of spring 15, pushing back or scraping off the particles stuck in the screen holes, ensuring that the screening process is continuous and efficient.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
