Description

Technical Field

[0001] This utility model relates to the field of mineral sorting equipment technology, specifically designing a spiral chute slope adjustment device. Background Technology

[0002] Spiral sluices are gravity separation devices widely used in mineral processing and material separation, typically for handling materials of varying densities. Their working principle involves using an inclined spiral channel to provide separation paths for materials with different properties. Under the combined action of gravity and centrifugal force, materials slide down the inclined spiral surface along a predetermined trajectory. From the inside to the outside of the sluice, based on differences in particle size and density, granular materials gradually achieve stratification, with high-density solid particles tending to converge towards the inside of the sluice, while low-density particles gradually aggregate towards the outside. This efficient and simple separation method makes spiral sluices highly valuable in material separation processes.

[0003] A spiral chute-type mineral processing device, with application number CN202122147340.5, includes a spiral chute body, a central column, a feed pipe, a feed bucket, several diversion pipes installed on the feed bucket, a ore-cutting component, and fasteners for fixing the ore-cutting component. During operation, the feed pipe delivers slurry to the feed bucket. The feed bucket and the several diversion pipes work together to evenly distribute the slurry, providing uniform feeding to the spiral chute body. The slurry flows through the spiral chute body for mineral separation. When the slurry reaches the discharge end of the spiral chute, the ore-cutting component at that point assists in diverting the slurry, facilitating slurry separation and discharge. The slurry is separated into concentrate and tailings and discharged to the collection area, completing the mineral processing. The ore-cutting component can rotate relative to the spiral chute body to adjust its cutting direction, and its position is fixed by fasteners. This facilitates the spiral chute body's ability to process multiple minerals, improving the versatility of the spiral chute body.

[0004] However, the existing technology still has a problem: the existing technology uses a single spiral chute with a fixed slope, which cannot adjust the slope at will according to different material characteristics, thus limiting its adaptability to diverse mineral sorting conditions. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a spiral chute slope adjustment device, which can flexibly adjust the slope through the combination structure of multiple spiral chutes to adapt to different material sorting requirements and improve sorting efficiency.

[0006] This utility model adopts the following technical solution: a spiral chute slope adjustment device, the adjustment device comprising: a support, hollow in the middle, with through grooves opened on both side walls along the length direction, and a support plate provided on the inner side of the side walls; a vertical plate, slidably connected in the through grooves, and rising and falling along the length direction of the through grooves; a spiral chute body, placed in the hollow part of the support, comprising: a centrally located central column, and several spiral layers that are mutually limited and slidably connected in the vertical direction, the upper and lower ends of the spiral layers respectively abutting against the support plate; wherein, the spiral layer comprises: an inner spiral layer, the inner side wall of which is fixed to the central column; an outer spiral layer, the outer side wall of which is fixed to the vertical plate; and several spiral connecting layers, adjacent spiral connecting layers being interconnected, and the spiral connecting layers on both sides respectively connecting the inner spiral layer and the outer spiral layer;

[0007] The vertical plate drives the outer spiral layer to rise, and simultaneously links several adjacent spiral connecting layers to rise in sequence, so that the slopes of the outer spiral layer, several spiral connecting layers and the inner spiral layer form a stepped slope.

[0008] As a preferred technical solution of this utility model, a lifting device is also provided, located on the outside of the support, comprising: a fixed frame, fixedly connected to the side wall of the support, with its two ends respectively located on both sides of the through groove; a rotating rod, rotatably connected between the fixed frames, with a gear sleeved on it; one end extending horizontally and penetrating through the fixed frame; a motor, the output end of which is coaxially connected to the extended end of the rotating rod; and a gear plate, fixedly connected to the vertical plate and meshing with the gear on the rotating rod; wherein, the motor drives the rotating rod to rotate, and the meshing of the gear and the gear plate drives the gear plate to rise and fall, thereby realizing the lifting and lowering movement of the vertical plate.

[0009] In a preferred embodiment of this invention, adjacent spiral layers are provided with mutually cooperating limiting portions, the limiting portions having an L-shaped cross-section. When the outer spiral layer rises, it causes the lower limiting portion to slide towards the upper limiting portion of the adjacent spiral layer until they engage, thus achieving a mutually limiting sliding connection between the spiral layers. The maximum distance the vertical plate can move up and down within the through groove is the sum of the sliding distances of the limiting portions of each adjacent spiral layer.

[0010] As a preferred technical solution of this utility model, in the vertical direction, a connecting block is fixedly provided at the edge of each spiral conveying section of the outer spiral layer corresponding to the vertical plate. The outer spiral layer and the vertical plate are fixedly connected by the connecting block to achieve synchronous lifting.

[0011] As a preferred technical solution of this utility model, a plurality of connecting plates are provided between the two side walls of the bracket, and the connecting plates include a first connecting plate, a second connecting plate and a third connecting plate that respectively connect the upper, middle and lower parts of the two side walls.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This application achieves the vertical lifting and lowering of the outer spiral layer by using vertical plates that are slidably connected within the through grooves on both sides of the support. The lifting and lowering movement of the vertical plates not only directly drives the outer spiral layer, which is fixed to them, to rise or fall, but also ensures that the outer spiral layer, spiral connecting layer, and inner spiral layer move in sync during adjustment through the mutual sliding and locking of the limiting parts between several spiral layers, forming a continuous stepped slope. This solves the problem caused by the existing single spiral chute having only a single fixed slope. This device can flexibly adjust the slope according to the sorting requirements of different materials, thereby adapting to diverse mineral sorting conditions while improving the stability of material sliding transmission and sorting accuracy.

[0025] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This utility model relates to a spiral chute slope adjustment device. Please refer to [link / reference]. Figures 1 to 8 As shown, the adjustment device includes: a support 1, hollow in the middle, with through grooves 3 on both side walls 2 along the length direction, and a support plate 4 on the inner side of the side walls 2; a vertical plate 5, slidably connected in the through grooves 3, and rising and falling along the length direction of the through grooves 3; and a spiral chute body 6, placed in the hollow part of the support 1, including: a central column 61 set in the center, and several spiral layers that are mutually limited and slidably connected in the vertical direction, with the upper and lower ends of the spiral layers respectively abutting against the support plate 4; wherein, the spiral layers include: an inner spiral layer 62, whose inner side wall 2 is fixed to the central column 61; an outer spiral layer 63, whose outer side wall 2 is fixed to the vertical plate 5; and several spiral connecting layers 64, which are interconnected with each other, and the spiral connecting layers 64 located on both sides are respectively connected to the inner spiral layer 62 and the outer spiral layer 63; the outer spiral layer 63 is driven to rise by the vertical plate 5, and the several adjacent spiral connecting layers 64 are raised in sequence in sync, so that the slopes of the outer spiral layer 63, the several spiral connecting layers 64 and the inner spiral layer 62 form a stepped slope.

[0027] Specifically, the device includes a support 1, a vertical plate 5, and a spiral chute body 6. The support 1 is hollow in the middle, and its two side walls 2 have through grooves 3 along their length to guide the sliding of the vertical plate 5. A support plate 4 is provided on the inner side of the side wall 2 of the support 1 to support the upper and lower ends of the spiral chute body 6. This allows each spiral layer to abut against the support plate 4 through its upper and lower ends when the vertical plate 5 is in its initial position or when no lifting or lowering adjustment is made, forming a continuous slope. That is, several spiral layers sink naturally under the action of gravity. Through the abutment relationship between their upper and lower ends and the support plate 4, the height consistency and slope smoothness of the spiral chute slope are ensured, and the relative positions between the spiral layers are maintained, thus forming an initial state similar to that of a single spiral chute with a fixed slope in the prior art. The vertical plate 5 is slidably connected in the through groove 3 of the support 1 and can be raised and lowered along the length of the through groove 3. Its outer side wall 2 is fixedly connected to one side wall 2 of the outer spiral layer 63 of the spiral chute body 6, so that the raising and lowering of the vertical plate 5 can directly drive the raising or lowering of the outer spiral layer 63. The spiral chute body 6 is supported by a central column 61. Its inner spiral layer 62 is stably connected to the inner wall 2 of the central column 61. Multiple spiral connecting layers 64 are mutually limiting and slidingly connected and located between the inner spiral layer 62 and the outer spiral layer 63, forming a linkage structure. That is, through the lifting and lowering movement of the vertical plate 5, the outer spiral layer 63 is driven to rise or fall. At the same time, through the limiting and sliding action of the spiral connecting layers 64, the slope of the outer spiral layer 63, the spiral connecting layer 64 and the inner spiral layer 62 in the entire spiral chute body 6 forms a height difference layer by layer and presents a stepped slope. The lifting and lowering of the vertical plate 5 not only adjusts the height of the outer spiral layer 63, but also realizes the flexible adjustment of the slope of the entire chute through the linkage of adjacent connecting layers, thereby optimizing the movement trajectory of materials on the slope, reasonably controlling the sliding speed, and enhancing the adaptability to different materials.

[0028] Furthermore, referring to Figure 5 As shown, a lifting device is also provided, located on the outside of the support 1, including: a fixed frame 7, fixedly connected to the side wall 2 of the support 1, with its two ends respectively located on both sides of the through groove 3; a rotating rod 8, rotatably connected between the fixed frames 7, with a gear 11 sleeved on it; one end extends horizontally and passes through the fixed frame 7; a motor 9, the output end of which is coaxially connected to the extended end of the rotating rod 8; and a toothed plate 10, fixedly connected to the vertical plate 5, meshing with the gear 11 on the rotating rod 8; wherein, the motor 9 drives the rotating rod 8 to rotate, and through the meshing of the gear 11 and the toothed plate 10, drives the toothed plate 10 to rise and fall, so as to realize the rising and falling movement of the vertical plate 5.

[0029] The lifting device is located on the outside of the support 1 and is used to drive the vertical plate 5 to move up and down in the through groove 3. It includes a fixed frame 7, a rotating rod 8, a motor 9, and a transmission structure of gear 11 and toothed plate 10. The fixed frame 7 is fixed to the side wall 2 of the support 1 and is located on both sides of the through groove 3 to provide a solid support frame for the lifting device. The rotating rod 8 is rotatably connected to the fixed frame 7 at both ends to ensure that it rotates along the axis. The gear 11 is sleeved in the middle of the rotating rod 8 and rotates synchronously with the rotating rod 8. One end of the rotating rod 8 extends horizontally and passes through the fixed frame 7 and is coaxially connected to the motor 9 installed on the outside. The motor 9 serves as a power source and drives the rotating rod 8 to rotate through its rotational motion, thereby driving the gear 11 to mesh with the toothed plate 10. The toothed plate 10 is fixed to the surface of the vertical plate 5 so that when the gear 11 rotates, the meshing action between the gear 11 and the toothed plate 10 can be used to convert the rotary motion into linear motion, thereby driving the vertical plate 5 to move up and down along the length of the through groove 3. During the operation of the structure, the motor 9 controls the vertical plate 5 to adjust its displacement. The lifting of the vertical plate 5 directly drives the movement of the outer spiral layer 63. Through the sliding limit linkage between each adjacent spiral connecting layer 64, the overall slope of the spiral chute is raised or lowered in sequence to form a stepped slope.

[0030] Furthermore, adjacent spiral layers are provided with mutually cooperating limiting parts, the limiting parts having an L-shaped cross section; wherein, when the outer spiral layer rises, it drives the limiting part at the lower end to slide towards the upper limiting part of the adjacent spiral layer until they are engaged, so as to realize the mutual limiting sliding connection between several spiral layers.

[0031] Specifically, adjacent spiral layers are provided with mutually cooperating limiting parts to ensure stable linkage connection of the spiral layers during the lifting and lowering process, and to achieve sliding limitation of the structure through snap-fit ​​engagement. The limiting part has an L-shaped cross-section, in which the limiting part of each spiral layer cooperates with the limiting part of its adjacent spiral layer. When the outer spiral layer rises under the drive of the vertical plate 5, its lower L-shaped limiting part slides along the upper limiting part of the adjacent spiral layer until the limiting parts of the two engage and form a stable linkage relationship, realizing the sliding limiting connection between several spiral layers.

[0032] Furthermore, the maximum distance that the vertical plate 5 can move up and down within the through groove 3 is the sum of the sliding distances of the limiting parts of each adjacent spiral layer.

[0033] In a preferred embodiment, the maximum lifting distance of the vertical plate 5 within the through groove 3 is set as the sum of the sliding distances of the limiting parts of each adjacent spiral layer. This is to ensure structural stability between the spiral layers while achieving slope adjustment. Specifically, when the vertical plate 5 rises or falls within the through groove 3, it drives the entire spiral chute upwards or downwards via its fixed outer spiral layer 63. The movement of the outer spiral layer 63 further drives the limiting parts between adjacent spiral layers to slide along the limiting path until the lower L-shaped limiting part engages with the adjacent upper L-shaped limiting part. When the vertical plate 5 reaches its maximum lifting distance within the through groove 3, the sliding distances of the limiting parts of adjacent spiral layers are fully accumulated, and all spiral layers are restricted to their extreme sliding positions. This structural design ensures that the lifting range of the vertical plate 5 matches the movement range of the spiral layer sliding mechanism, preventing separation or misalignment of the spiral layers due to excessive lifting or the limiting parts exceeding the engagement range.

[0034] Furthermore, in the vertical direction, a connecting block 13 is fixedly provided at the edge of each spiral conveying section of the outer spiral layer 63 corresponding to the vertical plate 5. The outer spiral layer 63 and the vertical plate 5 are fixedly connected by the connecting block 13 to achieve synchronous lifting.

[0035] Furthermore, a number of connecting plates are provided between the two side walls 2 of the support 1. The connecting plates include a first connecting plate 14, a second connecting plate 15, and a third connecting plate 16 that connect the upper, middle, and lower parts of the two side walls 2, respectively. The connecting plate structure connects the two side walls 2 through the distribution of the upper, middle, and lower sections, which enhances the rigidity of the support 1, maintains the stability of its shape, and prevents the side walls 2 from deforming during load bearing and movement.
