Description

Technical Field

[0001] This utility model belongs to the field of mining machinery technology, and in particular relates to an integrated device for continuous mineral transportation and vertical lifting. Background Technology

[0002] Traditional mineral transport hoisting systems suffer from discontinuous processes, low efficiency, high energy consumption, numerous potential failure points, large space requirements, and material damage due to the separation of horizontal transport and vertical hoisting, the presence of forced transfer points, and limitations in tilt angle, space, and efficiency of vertical hoisting technology. These issues make them unsuitable for modern, large-scale, and energy-efficient mineral transport. Therefore, a novel mechanism is urgently needed that seamlessly integrates continuous horizontal transport and vertical hoisting functions. This mechanism should effectively eliminate transfer points, achieve truly continuous transport from start to finish, overcome the tilt angle limitations of existing vertical hoisting technology, improve the overall system efficiency, reliability, and economy, and adapt to demanding spatial requirements.

[0003] Chinese patent document CN201632212U discloses a portable underground mixer, comprising a mixing device, a vertical conveying device, and a horizontal conveying device. The mixing device includes a mixing drum, mixing arms, a mixing motor, and a mixing reducer. The mixing device is mounted on a vertical frame. The discharge port of the horizontal conveying device is connected to the vertical conveying device, and a conveying pipe on the vertical conveying device is connected to the mixing drum. Through mechanical transmission and mixing, sand, gravel, and cement are uniformly mixed and then directly unloaded into a mine car. Mechanical operation reduces the labor intensity of operators, decreases the number of workers required, and improves work efficiency.

[0004] In the aforementioned patented solution, two horizontally and vertically arranged spiral conveyor devices can first transport materials horizontally and then vertically. The feeding speed of the hopper in the horizontal conveyor determines the overall conveying efficiency of the system. However, in practical applications, underground materials are often transported horizontally or at an angle by mine cars, and then manually or mechanically added to the hopper of the horizontal conveyor for vertical transfer. Clearly, both the mine cars and the horizontal conveyor are horizontal conveying devices; this redundant equipment results in a complex and redundant structure for the entire conveying system, occupying a large amount of space. Furthermore, the process of transferring material from the mine cars into the hopper of the horizontal conveyor also restricts the overall conveying efficiency. Utility Model Content

[0005] To overcome the technical problems of existing horizontal and vertical conveying equipment used in mineral hoisting and transportation, such as the redundant structure of the mine cars and horizontal conveying equipment resulting in a large space occupation of the entire conveying system, and the slow transfer speed of materials from the mine cars to the horizontal conveying equipment, which restricts the overall conveying efficiency, this utility model aims to provide an integrated device for continuous mineral transportation and vertical hoisting. By placing the discharge hopper at the bottom of the conveying cylinder below the circulating track, and setting a lifting track for the inclined railcar on the side of the circulating track near the discharge hopper, the railcar transporting horizontal materials directly flips the material into the discharge hopper, and then the conveying cylinder performs vertical transport. This simplifies the conveying structure, increases the material transfer rate, and thus improves the conveying efficiency.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an integrated device for continuous mineral transport and vertical lifting, comprising a feed hopper, a conveying cylinder longitudinally arranged on the feed hopper, a spiral conveying shaft rotatably connected inside the conveying cylinder, and a discharge hopper arranged at the upper end of the conveying cylinder; a conveyor belt is arranged on one side of the discharge hopper; a circulating track is arranged above the feed hopper; at least one railcar is arranged on the circulating track; wherein, the railcar includes a car body slidably connected to the circulating track, a car bucket rotatably connected to the car body near the conveying cylinder, a side opening arranged on the end of the car bucket facing the conveying cylinder, and an auxiliary wheel arranged on the side of the car bucket away from the conveying cylinder; a lifting track is arranged on the circulating track for driving the auxiliary wheel to move upward; the lifting track is directly opposite the feed hopper.

[0007] The railcar performs horizontal transport along the circular track. When it passes the lifting track, the auxiliary wheel slides along the lifting track, causing the hopper to tilt. The transported material slides into the feed hopper through the side opening under the action of gravity, and is then transported upward by the conveying cylinder until it is transported onto the conveyor belt.

[0008] Furthermore, the truck bed is provided with a sealing plate for closing the side opening; a support arm is provided on the upper side of the sealing plate away from the conveying cylinder; the middle part of the support arm is rotatably connected to the upper end of the truck bed; a connecting rod is provided between the end of the support arm away from the sealing plate and the vehicle body, and the two ends of the connecting rod are rotatably connected to the support arm and the vehicle body respectively.

[0009] When the hopper is in a horizontal position, the sealing plate closes the side opening, ensuring the hopper's capacity. When the hopper is tilted, the connecting rod pulls the support arm to flip the sealing plate, opening the side opening, and the material in the hopper is transferred into the feed hopper.

[0010] Specifically, the discharge hopper has a discharge port on the side near the conveyor belt; baffles extending towards the conveyor belt are respectively provided on both sides of the discharge port on the discharge hopper.

[0011] Specifically, the feed hopper has a semi-circular cross-sectional shape, and the center of the semi-circle coincides with the axis of the conveying cylinder; the lower end of the conveying cylinder is provided with an opening communicating with the feed hopper.

[0012] Specifically, the lifting track is a semi-circular track that arches upwards.

[0013] Preferably, the conveyor belt is provided with a dust cover, which is an inverted U-shaped structure.

[0014] Furthermore, the discharge hopper is a conical shell with its tip located at the bottom; the central axis of the conical shell is coaxial with the central axis of the conveying cylinder.

[0015] Preferably, an arc-shaped joint is provided at the connection between the side wall of the truck bed away from the side opening and the inner bottom of the truck bed. The arc-shaped joint can effectively prevent materials from adhering to or getting stuck in the inner bottom of the truck bed.

[0016] Optionally, a swing arm is rotatably connected to the lower end of the side of the truck bed away from the side opening; the rotation axis of the swing arm is arranged along the travel direction of the vehicle body; the auxiliary wheel is rotatably connected to the lower end of the swing arm; the rotation axis of the auxiliary wheel is perpendicular to the travel direction of the vehicle body.

[0017] Optionally, a limiting plate is provided above the lifting track; the auxiliary wheel slides between the lifting track and the limiting plate; the limiting plate is used to prevent the auxiliary wheel from detaching from the upper end of the lifting track.

[0018] The movable swing arm allows the support angle between the auxiliary wheel and the lifting track to change in real time with the movement of the track vehicle, and the outer circumference of the auxiliary wheel maintains a large contact area with the lifting track, resulting in higher overall structural strength.

[0019] Specifically, the circular track includes two parallel guide rails; the lower end of the vehicle body is provided with two pairs of wheels that abut against the two guide rails respectively.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model is used for horizontal and vertical material conveying, and is particularly suitable for use in scenarios with limited space, such as mines / tunnels.

[0022] 2. This utility model integrates the railcar used for horizontal conveying and the conveying cylinder used for vertical conveying, thereby reducing structural redundancy, simplifying structural features, and reducing the volume and space occupation of the conveying device.

[0023] 3. During the transportation process along the circular track, when the railcar passes through the raised track, the hopper tilts and the sealing plate opens automatically. The transported material falls quickly into the feed hopper under the action of gravity, realizing the rapid transfer of materials and improving the conveying efficiency of the integrated device.

[0035] The railcar 4 includes a car body 41 slidably connected to the circulating track 31, a bucket 42 rotatably connected to the car body 41 near the side of the conveying cylinder 11, a side opening 421 provided on the bucket 42 facing the conveying cylinder 11, a sealing plate 43 rotatably connected to the bucket 42 for selectively closing the side opening 421, and an auxiliary wheel 45 provided on the lower end of the bucket 42 away from the conveying cylinder 11.

[0036] The circulation track 31 is provided with a lifting track 32 for driving the auxiliary wheel 45 to move upward; the lifting track 32 is directly opposite the feed hopper 13; the lifting track 32 is a semi-circular track that arches upward.

[0037] A support arm 431 is provided on the side of the upper end of the sealing plate 43 away from the conveying cylinder 11; the middle part of the support arm 431 is rotatably connected to the upper end of the bucket 42; a central shaft 423 is provided on the upper end of the bucket 42 and is rotatably connected to the middle part of the support arm 431; a connecting rod 44 is provided between the end of the support arm 431 away from the sealing plate 43 and the vehicle body 41, and the two ends of the connecting rod 44 are rotatably connected to the support arm 431 and the vehicle body 41 respectively.

[0038] The discharge hopper 14 is provided with a discharge port 141 on the side near the conveyor belt 21; baffles 142 extending toward the conveyor belt 21 are respectively provided on both sides of the discharge port 141 on the discharge hopper 14. The discharge hopper 14 is a conical shell with the tip facing downward; the central axis of the conical shell is coaxial with the central axis of the conveying cylinder 11.

[0039] The feed hopper 13 has a semi-circular cross-sectional shape, and the center of the semi-circle coincides with the axis of the conveying cylinder 11; the lower end of the conveying cylinder 11 is provided with an opening communicating with the feed hopper 13.

[0040] The conveyor belt 21 is equipped with a dust cover 22, which is an inverted U-shaped structure. An arc-shaped joint 422 is provided at the connection between the side wall of the hopper 42 away from the side opening 421 and the inner bottom end of the hopper 42. This arc-shaped joint 422 effectively prevents material from adhering to or getting stuck at the inner bottom end of the hopper 42. The circulating track 31 includes two parallel guide rails; the lower end of the vehicle body 41 is provided with two pairs of wheels that abut against the two guide rails respectively.

[0041] A swing arm 46 is rotatably connected to the lower end of the side of the truck bed 42 away from the side opening 421; the rotation axis of the swing arm 46 is set along the travel direction of the vehicle body 41; an auxiliary wheel 45 is rotatably connected to the lower end of the swing arm 46; the rotation axis of the auxiliary wheel 45 is perpendicular to the travel direction of the vehicle body 41.

[0042] Workflow: The track car 4 slides along the circulating track 31 to horizontally transport materials. When the track car 4 passes the feed hopper 13, the auxiliary wheel 45 slides along the lifting track 32. The auxiliary wheel 45 moves upward, causing the hopper 42 to rotate and tilt towards the conveyor cylinder 11. The relative movement between the hopper 42 and the car body 41 causes the connecting rod 44 to pull the support arm 431, which in turn causes the sealing plate 43 to rotate. The sealing plate 43 no longer closes the side opening 421, and the material in the hopper 42 slides down into the feed hopper 13 under the action of gravity. The material entering the feed hopper 13 moves upward under the conveying of the screw conveyor shaft 12 and then enters the discharge hopper 14. The material in the discharge hopper 14 falls onto the conveyor belt 21 through the discharge port 141 and continues to be transported to the next stage.

[0043] After the auxiliary wheel 45 leaves the lifting track 32, the hopper 42 rotates downward to its original position, the sealing plate 43 rotates to re-close the side opening 421, and the railcar 4 continues to slide along the circular track 31 for the next transfer, and so on.

[0044] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
