A discharge device for increasing the throughput of a spiral chute

Abstract

This utility model discloses a discharge device for improving the throughput of a spiral chute. It consists of a base, mounting columns, and a chute body. The bottom of the chute body features a gradually expanding discharge plate with a trapezoidal design and a 15-30 degree inclination angle, effectively widening the material flow channel. Two rotatable diverting components are mounted on the discharge plate. Angle adjustment is achieved through the cooperation of a diverting head, locking column, and nut, allowing for precise matching of different material flow trajectories. A guiding component is slidably connected to the diverting components via a guiding rod and a second connecting part, further increasing the material flow channel in conjunction with the gradually expanding discharge plate. The linkage component uses a gear and rack drive; operating a single drive handle simultaneously controls both diverting components, simplifying the adjustment process. Through the synergistic effect of the gradually expanding flow channel and the intelligent adjustment mechanism, both the material throughput and sorting accuracy are improved, and the device is easy to operate and runs stably.

Description

Technical Field

[0001] This utility model relates to the field of spiral chute equipment, specifically to a discharge device for improving the throughput of a spiral chute. Background Technology

[0002] The discharge device of the spiral chute is a component of the spiral sorting equipment. Located at the end of the spiral chute, it is responsible for collecting, separating and discharging different minerals after sorting. Its function is to ensure that minerals are accurately separated according to density and particle size differences, while also affecting the equipment's throughput, sorting efficiency and stability.

[0003] The adjustable discharge device used in spiral chutes requires operators to adjust multiple independent baffles one by one. The adjustment process is cumbersome and time-consuming, and it is difficult to ensure the coordination between the baffles. In addition, in terms of discharge mechanism, the existing discharge device relies on gravity and centrifugal force and lacks active control means, which leads to limited slurry flow rate and difficulty in increasing the processing capacity. This passive discharge mode restricts the equipment's processing capacity. Utility Model Content

This increases the throughput of the discharge device while solving the problem of ore congestion caused by the narrow discharge port in traditional systems. Two linked flow diversion components move synchronously when one is adjusted, improving the ease of operation. Attached Figure Description

Detailed Implementation

[0025] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0026] Example 1:

[0027] like Figures 1 to 3 As shown, this utility model provides a discharge device for improving the throughput of a spiral chute, including a base 1, a mounting column 2 on the base 1, and a chute body 3 on the outer side of the mounting column 2, and further including:

[0028] The gradually expanding discharge plate 4 is located at the bottom of the chute body 3 and is used to receive the ore flowing through the surface of the chute body 3.

[0029] Two diversion components are provided, both of which are mounted on the gradually expanding discharge plate 4. The two diversion components can rotate relative to the surface of the gradually expanding discharge plate 4 to adjust accordingly to the flow trajectory of the ore.

[0030] A flow guiding component is disposed on the gradually expanding discharge plate 4 and is movably connected to the flow diversion component. The flow guiding component can rotate relative to the surface of the gradually expanding discharge plate 4 to increase the area through which the ore flows.

[0031] The linkage component is set on the splitter component and is used to drive the two splitter components to move synchronously.

[0032] In use, the ore is fed into the spiral chute body 3, and the ore spirals down along the surface of the chute. When the ore reaches the bottom, it falls onto the gradually expanding discharge plate 4, and the flow channel of the ore gradually expands. According to the properties of different ore, the angle of the two diversion components is adjusted to guide the flow of the ore. The flow guiding component further expands the flow area of ​​the ore by rotating. The two diversion components are synchronously adjusted through a linkage device. The operator only needs to adjust one control point to change the position of the two diversion plates at the same time, which greatly simplifies the operation process.

[0033] Example 2:

[0034] like Figures 1 to 3 As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, the gradually expanding discharge plate 4 includes a bottom plate 41 and two side plates 42. The two side plates 42 are welded to both sides of the bottom plate 41. The bottom plate 41 is trapezoidal in shape, and one end of the gradually expanding discharge plate 4 is fixedly connected to the bottom of the chute body 3. The discharge plate adopts a structure of trapezoidal bottom plate 41 and two side plates 42 welded together, and the area through which the ore flows gradually increases. The side plates 42 play a guiding role to ensure the smooth flow of the ore.

[0035] Furthermore, the gradually expanding discharge plate 4 is inclined, with an inclination angle between the gradually expanding discharge plate 4 and the horizontal plane ranging from 15 to 30 degrees. This inclined design of the gradually expanding discharge plate 4 allows the ore to maintain a stable flow rate, ensuring processing efficiency. The inclination angle between the gradually expanding discharge plate 4 and the horizontal plane is set within the range of 15-30 degrees. If the inclination angle is less than this range, it will affect the material's falling speed, causing concentrated material discharge and affecting the distribution effect. If the inclination angle is greater than this range, it will cause the material to fall too quickly, also affecting the distribution effect.

[0036] Furthermore, the diversion assembly includes a diversion head 5, on which a first connecting part 6 is fixedly installed. A locking post 7 is installed through the surface of the first connecting part 6. One end of the locking post 7 passes through the bottom plate 41 of the gradually expanding discharge plate 4. The portion of the locking post 7 outside the gradually expanding discharge plate 4 has a threaded groove, on which a nut 8 is threadedly connected. A locking cap 9 is fixedly installed on the portion of the locking post 7 on the upper surface of the first connecting part 6. Loosening the nut 8 adjusts the angle of the diversion head 5. After rotating the diversion head 5 to the desired position, tightening the bottom nut 8 fixes the diversion head 5 in place. The top locking cap 9 cooperates with the nut 8 to lock the diversion head 5.

[0037] Furthermore, the flow guiding assembly includes a flow guiding rod 10, on which a second connecting part 11 is fixedly mounted. A through hole is formed on the surface of the second connecting part 11, through which a locking pin 7 passes and is slidably connected. Loosening the nut 8 on the locking pin 7 releases the restriction on the flow guiding rod 10. The flow guiding rod 10 can be adjusted to a suitable angle according to actual usage needs, and then the nut 8 is tightened to fix the angle of the locking pin flow guiding rod 10, thereby increasing the channel through which the ore flows.

[0038] Furthermore, the linkage assembly includes two drive columns 12, each fixedly mounted on one of the two distributor heads 5. A drive handle 13 is fixedly mounted on each drive column 12, and a gear 14 is fixedly mounted on the outer side of each drive column 12. The two gears 14 are connected by a rack and pinion 15. Rotating either drive handle 13 will synchronously rotate the other drive column 12 via the gear 14 and rack and pinion 15.

[0039] Furthermore, a feed inlet 16 is provided at the top of the chute body 3. When the ore is poured into the feed inlet 16 at the top of the chute body 3, the ore will begin to rotate and slide down the natural slope of the spiral chute.

[0040] Furthermore, a collection box 17 is provided at the bottom of the sluice body 3. The collection box 17 is located at the bottom of the sluice, and the ore is automatically collected after sorting.

[0041] Furthermore, two partitions 18 are fixedly installed on the inner wall of the collection bin 17. The two partitions 18 are arranged parallel to each other, dividing the collection bin 17 into three equal parts for collecting different mineral materials. Mineral materials of different qualities will fall into the corresponding space according to the sorting results, saving time and effort while ensuring the sorting effect.

[0042] The working principle of the discharge device for increasing the throughput of a spiral chute described in this application is as follows:

[0043] In use, the ore slides down from the spiral chute body 3 and enters the gradually expanding discharge plate 4. The overall shape of the gradually expanding discharge plate 4 is trapezoidal, with the part that connects to the chute body 3 being the short side of the trapezoid, gradually expanding downwards to effectively enlarge the ore flow channel. Two diversion components are fixed to the discharge plate by locking pins 7 on the diversion head 5. The operator can loosen the nut 8 to adjust the angle of the diversion head 5 to match the ore flow trajectory. The guide rod 10 of the guide component is slidably connected to the locking pin 7 through the second connecting part 11, and can rotate freely to further expand the ore flow range. The linkage component connects the two drive pins 12 through the gear 14 and rack 15 transmission mechanism. By simply rotating one of the drive handles 13, the positions of the two diversion heads 5 can be adjusted synchronously. The entire device, through the gradually expanding flow channel design and linkage adjustment mechanism, increases the ore processing capacity and simplifies the operation process.

[0044] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
