Description

Technical Field

[0001] This invention relates to a vibratory ore feeder suitable for underground mines, belonging to the technical field of ore transfer equipment. Background Technology

[0002] Vibratory ore feeders, as key equipment for controlling ore transportation in underground mining, are widely used in critical stages such as ore pass discharge and ore bin unloading due to their simple structure, high unloading efficiency, and adaptability to harsh underground working conditions. The core structure of existing vibratory ore feeders typically includes a support base, a feeding frame, a vibratory motor, elastic support elements, and a feeding platform. Its working principle involves the excitation force generated by the vibratory motor driving the feeding platform to perform periodic vibrations, causing the ore on the platform to move in a set direction, ultimately completing the unloading operation.

[0003] However, in actual underground mining operations, the core working principle of vibratory ore feeders has become a key bottleneck restricting the accuracy of ore delivery. The conveying and delivery of ore relies entirely on vibration. Under periodic vibration, the ore in the feed trough continuously jumps along a parabolic trajectory, and its trajectory is prone to deviating from the preset delivery direction, resulting in inaccurate delivery of the ore into the transport vehicle. Specifically, firstly, the vibration force output by the vibrator is prone to directional deviation during long-term operation, or slight deformation may occur due to mine blasting disturbances in the equipment installation foundation, causing the vibration trajectory of the feed trough to deviate from the design benchmark, directly leading to a shift in the ore delivery direction. Secondly, the feed openings of existing vibratory ore feeders are mostly fixed structures, only able to roughly limit the ore range through mechanical baffles, making it difficult to achieve precise alignment with the transport vehicle's feed inlet. Ultimately, this results in a large amount of ore deviating from the transport vehicle's feed inlet and leaking into the work area, not only wasting ore resources but also requiring additional manpower and equipment for cleanup, and posing safety hazards to personnel. Summary of the Invention

[0004] The purpose of this invention is to provide a vibratory ore feeder suitable for underground mines, which can improve the stability and accuracy of ore feed.

[0005] The present invention is achieved through the following technical solution.

[0006] A vibratory ore feeder suitable for underground mines, comprising:

[0007] frame;

[0008] The vibrating discharge mechanism installed on the frame includes a vibrating chamber with an internal ore conveying channel and a vibrating motor for driving the vibration of the vibrating chamber. The vibrating chamber has an outlet and an inlet at its two ends, respectively.

[0009] The ore discharge mechanism includes a drive assembly and a flow guide assembly with a flow guide groove. One end of the flow guide assembly is rotatably connected to the ore outlet of the vibrating chamber, and the other end forms a ore discharge port. The drive assembly drives the flow guide assembly to rotate, so that the flow guide assembly can be fixed at least in a first position or a second position. In the first position, the flow guide assembly extends forward relative to the ore outlet, and the flow guide groove connects to the ore outlet, with ore flowing through the flow guide groove and out of the ore discharge port. In the second position, the flow guide assembly flips upward relative to the ore outlet, so that the flow guide assembly is tightly attached to block the ore outlet.

[0010] The ore discharge adjustment mechanism has a discharge plate movably disposed at the ore discharge port. When the flow guiding component is in the first position, the discharge plate is used to adjust the flow cross-sectional area of ​​the ore discharge port. When the flow guiding component is in the second position, the discharge plate is located above the ore discharge port and overlaps with the vertical projection of the vibrating chamber.

[0011] As a further improvement of the present invention, the flow guiding assembly includes a flow guiding plate and two baffle plates respectively disposed on both sides of the flow guiding plate, the flow guiding plate and the two baffle plates forming the flow guiding groove; when in the first position, the flow guiding plate extends in the same direction as the ore outlet, and the flow guiding plate is inclined downward; when the flow guiding plate rotates upward from the first position to the second position, the flow guiding assembly rotates upward, and when in the second position, the flow guiding plate is inclined upward, and one end face of the ore outlet of the vibrating chamber abuts against the flow guiding plate.

[0012] As a further improvement of the present invention, when the flow guiding component rotates from the first position to the second position, the projection of the ore outlet along the vertical direction falls completely into the flow guiding groove.

[0013] As a further improvement of the present invention, when the flow guiding component is in the first position or the second position, the ore outlet end of the vibrating chamber always extends into the flow guiding groove.

[0014] As a further improvement of the present invention, when the flow guiding component rotates upward from the first position to the second position, the ore located in the flow guiding groove can flow into the vibration chamber under the action of gravity.

[0015] As a further improvement of the present invention, the drive assembly includes two telescopic hydraulic cylinders, which are symmetrically arranged along the flow guide assembly. One end of each telescopic hydraulic cylinder is throttle-connected to the frame, and the other end is rotatably connected to the outer wall of one of the baffle plates.

[0016] As a further improvement of the present invention, a vibrating table is provided at the bottom of the discharge hopper, the vibrating motor is driven to the vibrating table, and the vibrating table is mounted on the frame.

[0017] As a further improvement of the present invention, the bottom of the vibration table plate is connected to a plurality of elastic damping components disposed on the frame.

[0018] As a further improvement of the present invention, the ore discharge adjustment mechanism further includes a driving member for driving the discharge plate to rotate around the blocking plate to adjust the flow cross-sectional area of ​​the ore discharge port; the discharge plate is rotatably connected to the two blocking plates, one end of the driving member is drivenly connected to the discharge plate, and the other end is rotatably connected to the side wall of one of the blocking plates.

[0019] As a further improvement of the present invention, the frame includes a plurality of vertically arranged support columns and a concrete support base for fixing the plurality of support columns.

[0020] The beneficial effects of this invention are:

[0021] 1. When ore discharge is required, the drive component drives the guide component to rotate from the second position to the first position. The guide channel of the guide component precisely connects with the ore outlet of the vibrating chamber, forming a continuous ore flow path from the vibrating chamber conveying channel to the ore discharge outlet of the guide component. After the ore is discharged from the vibrating chamber outlet, its movement direction is restricted by the channel wall of the guide channel, preventing ore flow deviation and spillage due to vibration inertia. This allows the originally unpredictable vibrating ore flow to form a fixed conveying trajectory along the guide channel. At the same time, the movable discharge plate at the discharge outlet can flexibly adjust the flow cross-sectional area of ​​the discharge outlet, enabling precise control of the discharge flow rate, allowing the ore to flow out accurately and stably from the discharge outlet.

[0022] 2. When the flow guide component is in the first position, it extends forward to release ore; when it is in the second position, it flips up to block the ore outlet. This can significantly reduce the overall lateral space occupied by the equipment when ore release is not required, solving the pain points of narrow working space and inconvenient equipment movement and layout in underground mines.

[0023] 3. After the ore discharge is completed, the drive component drives the guide component to rotate from the first position to the second position. During this process, the guide plate of the guide component gradually changes from a downward tilting state to an upward tilting state. Under the action of gravity, the ore remaining in the guide trough flows back into the ore conveying channel of the vibrating chamber with the rotation of the guide plate, realizing the ore return without residue in the guide trough. There is no need for manual cleaning of the guide trough, which greatly improves the efficiency of the ore discharge operation. At the same time, it avoids the problem of ore falling and wasting caused by the ore remaining in the guide trough after the ore discharge is completed, which causes the discharge plate to close and jam.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0033] This embodiment provides a vibratory ore feeder suitable for underground mines, used to transfer ore from the mining face to a transport vehicle within an underground mine shaft. (Refer to...) Figure 1-6The system includes a frame 1, a vibrating discharge mechanism, a ore discharge mechanism, and an ore discharge adjustment mechanism. The frame 1 serves as the foundation support for the entire equipment, possessing sufficient structural strength and stability to adapt to the heavy-duty operating environment of underground mines. The vibrating discharge mechanism, mounted on the frame 1, includes a vibrating chamber 21 and a vibrating motor 22. An ore conveying channel is formed inside the vibrating chamber 21, with its extension direction matching the ore conveying direction. The vibrating chamber 21 has an inlet 21a and an outlet 21b at its two ends. The inlet 21a connects to the ore discharge end of the mining face, while the outlet 21b faces the ore transport vehicle. When the vibrating motor 22 operates, it drives the vibrating chamber 21 to generate high-frequency vibration. After the ore enters the ore conveying channel from the inlet 21a, it moves along the ore conveying channel towards the outlet 21b under the action of vibration, thus achieving vibratory conveying of the ore.

[0034] The ore discharge mechanism includes a drive assembly and a flow guide assembly 31. One end of the flow guide assembly 31 is rotatably connected to the outer wall of the ore outlet 21b of the vibrating chamber 21 via a hinge or hinge shaft. The other end of the flow guide assembly 31 forms a ore discharge outlet 34. A through flow guide groove 33 is formed inside the flow guide assembly 31. One end of the flow guide groove 33 corresponds to the ore outlet 21b, and the other end is connected to the ore discharge outlet 34. The drive assembly is used to drive the flow guide assembly 31 to rotate around its connection with the ore outlet 21b. The connection rotates and can at least fix the flow guide component 31 in a first position or a second position, wherein the first position is the ore discharge position and the second position is the sealing position. When in the first position, the flow guide component 31 extends forward relative to the ore outlet 21b, and the flow guide channel 33 connects to the ore outlet 21b. The ore flows through the flow guide channel 33 and flows out from the ore discharge port 34. When in the second position, the flow guide component 31 flips upward relative to the ore outlet 21b, so that the flow guide component 31 is tightly attached to seal the ore outlet 21b.

[0035] In this embodiment, the ore discharge adjustment mechanism includes a discharge plate 4, which is movably disposed at the ore discharge port 34. When the flow guiding component 31 is in the first position, the area of ​​the discharge plate 4 blocking the ore discharge port 34 can be changed by moving the discharge plate 4, thereby adjusting the flow cross-sectional area of ​​the ore discharge port 34. When the flow guiding component 31 rotates to the second position to block the ore outlet 21b, the discharge plate 4 moves synchronously with the flow guiding component 31 and finally sits above the ore outlet 21b and overlaps with the vertical projection of the vibrating chamber 21, away from the ore conveying channel of the vibrating chamber 21, thus avoiding direct impact and wear of the ore on the discharge plate 4 and effectively extending the service life of the discharge plate 4.

[0036] When ore needs to be discharged, the drive component drives the flow guide component 31 to rotate from the second position to the first position. The flow guide trough 33 of the flow guide component 31 is precisely connected to the ore outlet 21b of the vibrating chamber 21, forming a continuous ore flow path from the conveying channel of the vibrating chamber 21 to the ore discharge outlet 34 of the flow guide component 31. After the ore is discharged from the ore outlet 21b of the vibrating chamber 21, its movement direction is restricted by the trough wall of the flow guide trough 33, preventing the ore flow from deviating or spilling due to vibration inertia. This allows the originally unpredictable vibrating ore flow to form a fixed conveying trajectory along the flow guide trough 33. At the same time, the discharge plate 4, which is movably set at the ore discharge outlet 34, can flexibly adjust the flow cross-sectional area of ​​the ore discharge outlet 34, enabling precise control of the ore discharge flow rate, so that the ore can flow out of the ore discharge outlet 34 accurately and stably.

[0037] Furthermore, when the flow guide component 31 is in the first position, it extends forward to discharge ore; when it is in the second position, it flips upward to block the ore outlet 21b. This significantly reduces the overall lateral space occupied by the equipment when ore discharge is not required, solving the pain points of narrow working space and inconvenient equipment movement and layout in underground mines. Moreover, the flow guide component 31 and the ore outlet 21b of the vibrating chamber 21 are rotatably connected. Combined with the mechanical drive of the drive component, the switching process is highly automated and easy to operate, adapting to the limited manual operating space in underground mines.

[0038] More specifically, the flow guiding component 31 includes a flow guiding plate 311 and two baffle plates 312. The two baffle plates 312 are vertically fixed to the two sides of the flow guiding plate 311. The flow guiding plate 311 and the two baffle plates 312 together form the aforementioned flow guiding channel 33. The height of the baffle plates 312 is higher than the ore outlet 21b, preventing ore from spilling from both sides of the flow guiding channel 33 and improving the stability of ore discharge. When the flow guiding component 31 is in the first position, the flow guiding plate 311 extends in the same direction as the ore outlet 21b of the vibrating chamber 21, and the flow guiding plate 311 is inclined downwards at an angle of 15°-30°. This ensures that the ore slides smoothly along the flow guiding channel 33 under the action of gravity and vibration transmission, while preventing the ore from sliding too fast and causing impact.

[0039] When it is necessary to stop ore discharge, the drive assembly drives the guide plate 311 to rotate upward from the first position to the second position. During this process, the ore outlet 21b of the vibrating chamber 21 gradually extends downward into the guide groove 33 of the guide assembly 31 until the end face of the ore outlet 21b away from the ore inlet 21a is tightly abutted against the inner wall of the guide plate 311, and the guide plate 311 is tilted upward at an angle of 30°-45°. At this time, the guide assembly 31 completely blocks the ore outlet 21b and achieves a surface contact seal, effectively preventing ore leakage.

[0040] Furthermore, when the flow guide component 31 is in the first or second position, the projection of the ore outlet 21b along the vertical direction falls completely into the flow guide groove 33 of the flow guide component 31, and one end of the ore outlet 21b of the vibrating chamber 21 always extends into the flow guide groove 33 of the flow guide component 31, which can prevent the ore at the ore outlet 21b from falling out of the flow guide component 31 during the rotation of the flow guide component 31.

[0041] The drive assembly includes two telescopic hydraulic cylinders 32, which are symmetrically arranged on both sides of the flow guide assembly 31. The cylinder body of the telescopic hydraulic cylinder 32 is rotatably connected to the outer wall of the frame 1 via a hinge, and the piston rod of the telescopic hydraulic cylinder 32 can also be connected to the outer wall of the baffle plate 312 on the corresponding side of the flow guide assembly 31 via a hinge. The two telescopic hydraulic cylinders 32 are synchronously controlled by the hydraulic system to achieve synchronous dual-side drive of the flow guide assembly 31, so that the force on the flow guide assembly 31 is uniform during rotation, avoiding positioning deviation caused by single-side drive, ensuring the stable fixation of the flow guide assembly 31 in the first and second positions, and improving the stability of equipment operation. The stroke of the telescopic hydraulic cylinder 32 is adapted to the rotation angle of the flow guide assembly 31, and the telescopic hydraulic cylinder 32 has a self-locking function, which can achieve self-locking when the piston rod is extended or retracted to a designated position, thereby stably fixing the flow guide assembly 31 in the first or second position.

[0042] In this embodiment, the ore discharge adjustment mechanism further includes at least one driving component (not shown in the figure). The discharge plate 4 is rotatably disposed at the discharge port 34 of the flow guiding assembly 31. The driving component can be a cylinder or an electric push rod. One fixed end of the driving component is rotatably connected to the baffle plate 312 of the flow guiding assembly 31, and the output end of the driving component is drively connected to the discharge plate 4 to drive the discharge plate 4 to rotate along the baffle plate 312. When the flow guiding assembly 31 is in the first position for ore discharge operation, the driving component drives the discharge plate 4 to rotate outward. By changing the area of ​​the discharge port 34 blocked by the discharge plate 4, the effective flow cross-sectional area of ​​the discharge port 34 is adjusted, thereby accurately controlling the ore discharge speed and discharge volume to adapt to the processing capacity of subsequent conveying equipment. The driving component can be disposed on the outer wall of the baffle plate 312 to avoid damage to the driving component from the ore. Furthermore, the number of driving components is preferably two, and they are symmetrically disposed on the two baffle plates 312 to drive the discharge plate 4 to rotate stably.

[0043] Furthermore, it should be noted that after ore discharge is completed, the discharge plate 4 should first be adjusted to close the discharge port 34 to prevent ore from overflowing from the transport vehicle and causing waste. However, at this time, a small amount of ore may remain in the guide trough 33, which can easily cause the discharge plate 4 to jam, preventing it from closing the discharge port 34 and causing ore to fall out of the discharge port 34, resulting in waste. In this embodiment, after ore discharge is completed, the drive component drives the guide component 31 to rotate from the first position to the second position. During this process, the guide plate 311 of the guide component 31 gradually changes from a downward tilting state to an upward tilting state. Under the action of gravity, the ore remaining in the guide trough 33 flows back into the ore conveying channel of the vibrating chamber 21 with the rotation of the guide plate 311, realizing the ore backflow without residue in the guide trough 33. There is no need for manual cleaning of the guide trough 33, which greatly improves the efficiency of ore discharge operation and avoids the problem of ore waste caused by the discharge plate 4 jamming due to ore residue remaining in the guide trough 33 after ore discharge.

[0044] In this embodiment, a vibration table is provided at the bottom of the vibration chamber 21, and the vibration motor 22 is drivenly connected to the vibration table. The vibration table is mounted on the frame 1. Furthermore, multiple elastic damping components are connected to the bottom of the vibration table, which is mounted on the frame 1. One end of each elastic damping component is connected to the bottom of the vibration table, and the other end is connected to the frame 1, thereby damping the vibration of the vibration chamber 21 table. These elastic damping components can be coil springs, elastic rubber, or other components with damping effects.

[0045] In this embodiment, the frame 1 includes a plurality of vertically arranged support columns 11 and a concrete support base 12 for fixing the plurality of support columns 11. The concrete support base 12 is supported on the ground, and one end of the support column 11 is fixed in the concrete support base 12 to achieve stable positioning of the support column 11 and prevent the equipment from shifting or shaking due to vibration.

[0046] The working process of the vibratory ore feeder of the present invention is as follows:

[0047] During the ore discharge operation, the two telescopic hydraulic cylinders 32 of the drive assembly retract synchronously, driving the flow guide assembly 31 to rotate to the first position and lock it. At this time, the flow guide trough 33 connects to the ore outlet 21b, and the vibration motor 22 drives the vibration chamber 21 to vibrate. The ore enters the ore conveying channel from the ore inlet 21a and moves towards the ore outlet 21b under the action of vibration. Then it enters the flow guide trough 33 and slides along the flow guide trough 33 towards the ore discharge outlet 34. According to the ore discharge requirements, the drive component of the ore discharge adjustment mechanism drives the discharge plate 4 to move, adjusting the flow cross-sectional area of ​​the ore discharge outlet 34 to achieve precise control of the ore discharge amount. The ore finally flows out from the ore discharge outlet 34 to the subsequent conveyor vehicle.

[0048] When the ore discharge stops, the two telescopic hydraulic cylinders 32 of the drive assembly extend synchronously, driving the flow guide assembly 31 to rotate upward from the first position to the second position and lock itself. During this process, the ore outlet 21b extends into the flow guide groove 33, and the end face of the ore outlet 21b abuts tightly with the flow guide plate 311, thereby achieving reliable sealing of the ore outlet 21b.

[0049] When the ore discharge resumes, the telescopic hydraulic cylinder 32 retracts synchronously, driving the flow guide assembly 31 to rotate from the second position to the first position.

[0050] The vibratory ore feeder of this invention has a reasonable structural design, which can adapt to the complex working environment of underground mines, effectively improve the efficiency of ore feeder operations and the service life of equipment, and has good practicality and promotion value.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
