Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to a material distribution device for a mining belt conveyor. Background Technology

[0002] As is well known, belt conveyors are often used to transport ore during the mining process. When the amount of incoming material is large, a material distribution device is often used to distribute the ore.

[0003] Currently, the material distribution device of belt conveyor plays a key role in material diversion. However, most belt conveyor material distribution devices use fixed baffles for material distribution, which requires stopping the machine and manually adjusting the material distribution direction when adjusting the baffles. Furthermore, when distributing material at a single point baffle, serious material accumulation is likely to occur, causing material stagnation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a material distribution device for mining belt conveyors, which solves the technical problems of existing material distribution devices, such as the inability to adjust the material distribution direction online and the easy accumulation and leakage of material at single points.

[0005] The technical solution adopted in the invention is: a material distribution device for a mining belt conveyor, including a main conveyor belt, the key technical point of which is that a material distribution component is fixedly installed on one side of the top of the main conveyor belt, and two parallel material distribution conveying components are installed on one side of the material distribution component. Both of the aforementioned material distribution and conveying assemblies include a material distribution conveyor belt and a support frame. The top left side of the support frame is rotatably connected to the bottom left side of the material distribution conveyor belt. An electric push rod is rotatably mounted on the right side of the support frame. The output end of the electric push rod is drively connected to the bottom right side of the material distribution conveyor belt to drive the material distribution conveyor belt to pitch around its left rotation point.

[0006] In the above scheme, adjustable side baffles are installed on both the front and rear sides of the top of the material distribution conveyor belt and on both the front and rear sides of the top of the main conveyor belt.

[0007] In the above scheme, the material distribution component includes a mounting frame, a third rotating shaft is provided through the top of the inner side of the mounting frame, the material distribution baffle is sleeved on the third rotating shaft and can rotate around its center line, the top of the mounting frame has an opening, the right side of the opening has an arc structure, a slider is fixedly installed on the right side of the top of the material distribution baffle, the slider is slidably connected to the inner right side of the opening, and a drive mechanism is fixedly installed on the rear side of the top of the mounting frame, the drive mechanism is drivingly connected to the material distribution baffle.

[0008] In the above scheme, the driving mechanism includes a cylinder, the output end of the cylinder is fixedly installed with a slide groove, the top of the material distribution baffle is fixedly installed with a slide rod, the top end of the slide rod extends into the interior of the slide groove and is slidably connected with the slide groove.

[0009] In the above scheme, a material distribution block is fixedly installed in the middle of the top right side of the inner side of the mounting frame. The material distribution block is located on the right side of the material distribution baffle. The material distribution block has a triangular prism structure with its pointed top facing upward.

[0010] In the above scheme, a transition shaft is provided between the front and rear sides inside the mounting frame and can rotate around its center line. The transition shaft is located between the main conveyor belt and the two material distribution conveyor belts.

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with the accompanying drawings. Figures 1-4 The present invention will be further described in detail below with reference to specific embodiments.

[0017] Reference Figure 1-4 A material distribution device for a mining belt conveyor includes a main conveyor belt 1. A material distribution component 2 is fixedly installed on one side of the top of the main conveyor belt 1. Two parallel material distribution conveying components 3 are installed on one side of the material distribution component 2. Each material distribution conveying component 3 includes a material distribution conveying belt and a support 4. The left side of the top of the support 4 is rotatably connected to the left side of the bottom of the material distribution conveying belt via a first rotating shaft. A second rotating shaft passes through the right side of the inside of the support 4. The cylinder end of an electric push rod 5 is sleeved on the second rotating shaft and can rotate around its center line. A connecting shaft passes through the right side of the bottom of the material distribution conveying belt and can rotate around its center line. The output end of the electric push rod 5 is fixedly connected to the outer surface of the connecting shaft.

[0018] Adjustable side baffles 6 are fixedly installed on both the front and rear sides of the top of the material distribution conveyor belt and the front and rear sides of the top of the main conveyor belt 1. The side baffles 6 are bolted to long grooves opened on the bracket or conveyor belt frame, and the lateral spacing of the side baffles 6 is adjusted by sliding the position of the bolts in the long grooves.

[0019] Material is input from the left side of the main conveyor belt 1 and enters the material distribution component 2. The material distribution component 2 can send the material into two material distribution conveyor components 3 as needed. The material distribution conveyor components 3 can transport the separated material to the next station.

[0020] The electric push rod 5 can drive the corresponding material distribution conveyor belt to rotate, causing the right side of the material distribution conveyor belt to rise, thereby conveying the material to a higher position. Through the two material distribution conveyor components 3, the material after distribution can be conveyed to different directions.

[0021] The material distribution assembly 2 includes a mounting frame 7. A third rotating shaft is inserted through the top of the inner side of the mounting frame 7. A material distribution baffle 10 is fitted onto the third rotating shaft and can rotate around its center line. The top of the mounting frame 7 has an opening 9. The right side of the opening 9 has an arc-shaped structure. A slider is fixedly installed on the right side of the top of the material distribution baffle 10. The slider is engaged and can slide inside the arc-shaped right side of the opening 9, thereby constraining the swing trajectory of the material distribution baffle 10. A drive mechanism is fixedly installed on the rear side of the top of the mounting frame 7. The drive mechanism is connected to the material distribution baffle 10 to drive it to rotate around the third rotating shaft. A material distribution block 8 is fixedly installed in the middle of the top right side of the inner side of the mounting frame 7. The material distribution block 8 is located on the right side of the material distribution baffle 10 and has a triangular prism structure. Its length direction is parallel to the running direction of the conveyor belt. The width of its bottom surface is greater than the gap between the main conveyor belt 1 and the material distribution conveyor belt. Its pointed top is set upward to divide the material flow, and its two inclined surfaces face the two material distribution conveyor belts respectively to guide the material. The material distribution block 8 can effectively block the gaps in the conveyor belt and prevent material leakage.

[0022] A sealing strip is fixedly installed at the bottom of the material distribution baffle 10. The gap between the sealing strip and the main conveyor belt 1 is ≤2mm, which can reduce material leakage and avoid frictional resistance.

[0023] When the material distribution baffle 10 is tilted to the left or right under the action of the drive mechanism, it can achieve directional diversion of materials. Taking the tilt to the left as an example: after the material transported along the main conveyor belt 1 arrives at the material distribution assembly 2, it first contacts the material distribution baffle 10, which is tilted to the left. Under the guiding action of the inclined surface of the baffle, the main flow of material is guided to the left. At the same time, the back of the material distribution baffle 10 and the left inclined surface of the triangular prism-shaped material distribution block 8 together form a continuous and smooth guiding channel from the main conveyor belt 1 to the left material distribution conveyor belt. This structure can effectively prevent materials from getting stuck or scattering at the gaps in the conveyor belt, ensuring that the materials fall smoothly and centrally into the left material distribution conveyor belt, completing the single diversion operation to the left.

[0024] When it is necessary to evenly distribute material to two distribution conveyor belts simultaneously, the cylinder 12 of the drive mechanism actuates, driving the distribution baffle 10 to rotate to a vertical position. At this time, the surface of the distribution baffle 10 is perpendicular to the running direction of the main conveyor belt 1, and its vertical lower edge is aligned with the tip of the triangular prism-shaped distribution block 8 along the conveying direction, together forming a bifurcation point. After the material flow from the main conveyor belt 1 arrives at this bifurcation point, it is evenly divided into two streams, which are guided along the left and right inclined surfaces of the distribution block 8 respectively, and smoothly enter the corresponding two distribution conveyor belts.

[0025] The specific structure and principle of the driving mechanism are as follows: It includes a cylinder 12 fixed to the top of the mounting frame 7, and a slide groove 13 is fixedly installed at the output end of the cylinder 12. A slide rod 14 is fixedly installed on the top of the material distribution baffle 10, and the top end of the slide rod 14 extends into the slide groove 13 and slides therewith. When the output rod of the cylinder 12 moves horizontally, it drives the slide groove 13 to move synchronously. The slide groove 13, through the sliding engagement between its inner wall and the slide rod 14, forces the slide rod 14 to drive the material distribution baffle 10 to rotate around the third rotation axis, thereby realizing the switching of the material distribution baffle 10 between the three working positions of left tilt, vertical, and right tilt.

[0026] Furthermore, inside the mounting frame 7, above the gap between the discharge end of the main conveyor belt 1 and the inlet ends of the two distribution conveyor belts, a transition shaft 11 is installed and can rotate around its own centerline. The function of this transition shaft 11 is to support materials that may fall, effectively preventing materials from falling from the gap and ensuring that all materials can be continuously and smoothly transferred from the main conveyor belt 1 to the target distribution conveyor belt.

[0027] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
