Description

Technical Field

[0001] This utility model relates to the field of spiral chute technology, and in particular to a mining spiral chute with an adjustable inclination angle. Background Technology

[0002] As an important mineral sorting device, the spiral chute is widely used in various mineral processing operations, especially when handling low-grade ores, fine-grained ores, and ores with complex compositions. Its high efficiency, economy, and environmental friendliness make it an indispensable tool. The working principle of the spiral chute is based on the difference in settling velocity of mineral particles of different densities in a fluid. Through the specific slope design and rotational motion of the spiral chute, materials can be stratified according to density and effectively separated.

[0003] Traditional mining spiral chutes typically employ a fixed inclination angle design. This means they can only be optimized for processing ores under specific conditions or types of ore. When dealing with ores of varying particle sizes, densities, or moisture content, a fixed inclination angle often fails to achieve ideal sorting results. For example, when processing finer-grained ores, a gentler slope may be needed to increase the residence time of mineral particles in the fluid; while for denser ores, a larger inclination angle may be required to ensure sufficient centrifugal force to promote stratification. Traditional fixed-inclination spiral chutes have significant limitations in adapting to diverse mineral processing needs, restricting their application range and efficiency. Therefore, it is necessary to design an adjustable-inclination mining spiral chute to address the shortcomings of existing technologies. Utility Model Content

[0007] As a further preferred embodiment, the connection between the movable rod and the corresponding sleeve rod is provided with sliding damping, and a groove with a certain movable length adapted to the sleeve rod is opened in the movable rod. The rotation adjustment angle of the spiral chute body on the rotating plate is limited.

[0008] As a further preferred embodiment, the adjusting component includes a motor, a bracket three, a connecting shaft, a worm gear, and a worm.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0021] An adjustable-angle mining spiral chute, such as Figures 1-4 As shown, the device includes a mounting base 1 and a spiral chute body 2. The mounting base 1 serves as the load-bearing carrier for the spiral chute, and the spiral chute body 2 is mounted on the mounting base 1. It also includes a support plate 201, a first bracket 202, a second bracket 3, a first hinge frame 4, and a rotating plate 5. A vertically supporting support plate 201 is fixedly connected to the rear side of the top surface of the mounting base 1. The first bracket 202 is hinged to the top of the support plate 201, and the first bracket 202 is fixedly connected to the spiral chute body 2. The spiral chute body 2 is hinged to the support plate 201 via the first bracket 202. Second brackets 3 are symmetrically fixedly connected to both sides of the spiral chute body 2, and the lower end of the second bracket 3 is hinged... A hinge frame 4 is connected, and a rotating plate 5 is rotatably connected to the hinge frame 4. Support members are provided on both sides of the top surface of the mounting base 1, which are used to support the spiral chute body 2. The support members are connected to and support the spiral chute body 2 from both sides through the rotating plate 5. An adjustment member is provided on the front side of the top surface of the mounting base 1 for adjusting the angle of the spiral chute body 2. After the spiral chute body 2 is stably supported by the support members on both sides, the processing angle of the spiral chute body 2 can be flexibly adjusted with the adjustment member, so that the spiral chute can adapt to the sorting requirements of ores with different particle sizes, densities or moisture content, and improve the applicability of the spiral chute.

[0022] like Figure 1 and Figure 2As shown, the support includes a movable rod 6, a sleeve rod 7, and a second hinge frame 8. The second hinge frame 8 is symmetrically fixed on both sides of the top surface of the mounting base 1. Each second hinge frame 8 is hinged with a sleeve rod 7. The end of the sleeve rod 7 is provided with a sliding groove. The sleeve rod 7 is slidably fitted with the movable rod 6 through the sliding groove. The movable rod 6 is fixedly connected to the rotating plate 5 on the same side. Through the sliding cooperation of the movable rod 6 with the sleeve rod 7, both sides of the spiral chute body 2 can be stably supported.

[0023] like Figure 2 and Figure 4 As shown, the connection between the movable rod 6 and the corresponding sleeve rod 7 is provided with sliding damping. The movable rod 6 is provided with a groove with a certain movable length suitable for the sleeve rod 7. The rotation adjustment angle of the spiral chute body 2 on the rotating plate 5 is limited.

[0024] like Figure 1 and Figure 3 As shown, the adjusting components include a motor 9, a bracket 10, a connecting shaft 11, a worm gear 12, and a worm 13. The motor 9 is fixedly installed on the front side of the top of the mounting base 1. The bracket 10 is fixedly connected to the front side of the spiral chute body 2. The connecting shaft 11 is fixedly connected to the bottom of the bracket 10. The worm gear 12 is fixedly installed on the connecting shaft 11. The worm 13 is fixedly connected to the output shaft of the motor 9. The worm gear 12 and the worm 13 mesh with each other. The motor 9 drives the worm gear 12 through the meshing of the worm 13, so that the worm gear 12 can synchronously drive the spiral chute body 2 through the bracket 3 to adjust the sorting angle. With the self-locking property of the worm gear 12 and the worm 13, the stability of the adjustment angle of the spiral chute body 2 is improved.

[0025] like Figure 1 and Figure 2 As shown, a limiting plate 14 is fixedly installed on the mounting base 1. Two limiting plates 14 are provided and symmetrically fixedly connected to both sides of the top surface of the mounting base 1. The sleeve rod 7 passes through the limiting plate 14 on the same side. The limiting plate 14 is used to limit the sleeve rod 7 on the hinge frame 8, so that the sleeve rod 7 can only rotate within a certain angle range, avoiding the reduction of stability caused by excessive angle adjustment of the spiral chute body 2.

[0026] like Figure 1 and Figure 3 As shown, it also includes an inclination sensor 15. The inclination sensor 15 is fixedly mounted on the bracket 3 10. The inclination sensor 15 is used to monitor the tilt angle of the spiral chute body 2 in real time. The user can use the inclination sensor 15 to accurately adjust the tilt angle required for mineral sorting.

[0027] When adjusting the inclination angle of the spiral chute is required for ore sorting, the operator first starts the motor 9 on the front side of the mounting base 1. The motor 9 drives the worm gear 13 on the output shaft to rotate. The worm gear 13 meshes with the worm wheel 12 fixed at the bottom of the support 3 10. The rotation of the worm gear 13 forces the worm wheel 12 to rotate around the connecting shaft 11, which in turn pushes the front side of the spiral chute body 2 to rotate through the support 3 10. The entire spiral chute body 2 will tilt in an arc-shaped trajectory with the hinge point at the top of the support plate 201 as the axis, thereby changing the longitudinal slope of the chute. During the tilting process of the spiral chute body 2, the spiral... The two symmetrically fixed supports 3 on both sides of the chute body 2 move synchronously. The hinge frame 4 at the end of the support 3 drives the rotating plate 5 to rotate around its own axis. The rotating plate 5 is fixedly connected to the movable rods 6 of the two side supports. After being pushed by the rotating plate 5, the movable rod 6 slides and extends within the groove of the sleeve rod 7. At the same time, the sleeve rod 7 swings slightly with the hinge frame 8 as the fulcrum, forming a stable support structure. This ensures that the two side supports are always in contact with the tilt direction of the chute body. Through the extension and retraction of the movable rod 6 and the sleeve rod 7, the lateral stress caused by the angle change of the chute is balanced, preventing the chute from shifting or shaking laterally. To ensure stability during the adjustment process, the limiting plates 14 on both sides of the mounting base 1 constrain the swing angle of the sleeve rod 7. When the sleeve rod 7 is pushed by the movable rod 6, the limiting plates 14 restrict the sleeve rod 7 to rotate only within the preset safe angle range, avoiding imbalance of the chute's center of gravity due to excessive tilting. After adjustment, the helix angle design of the worm gear 13 prevents external forces from driving the worm wheel 12 in the opposite direction, thereby locking the current angle. Even if the spiral chute body 2 is subjected to ore impact or vibration, the tilt angle can remain fixed. Furthermore, during the adjustment process, the tilt sensor 15 fixed on the bracket 10 monitors the tilt angle in real time. The tilt angle of the spiral chute body 2 is detected and fed back to the operator via a display device. The operator then fine-tunes the direction of the motor 9 according to the characteristics of the ore (e.g., large particles of ore require a smaller tilt angle to prevent splashing, while fine particles or high-moisture ore require a larger tilt angle to accelerate sorting). This allows the worm gear 13 to drive the worm wheel 12 to further precisely control the tilt angle. Ultimately, with the bidirectional stability of the two-sided support members and the rigid locking of the worm wheel 12 and worm gear 13, the spiral chute body 2 forms the optimal slope that meets the current ore sorting requirements, ensuring that the minerals are efficiently stratified and separated in the spiral chute by gravity, centrifugal force, and water flow.
