Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation technology, and in particular to a coal mine electromechanical transportation transmission device. Background Technology

[0002] During the mining process, coal mines need to use transport and transmission devices to transport the mined coal. Belt conveyors are commonly used for this purpose, and their reliability directly affects the efficiency and safety of coal mining.

[0003] When coal is loaded onto the conveyor belt, it is prone to spillage due to factors such as vibration, changes in tilt angle, or uneven material distribution. Spilled coal not only causes dust pollution and material waste in the working environment, but may also pose safety hazards to on-site workers. If coal enters the interior of the conveyor, it can cause equipment jamming, belt misalignment, and other malfunctions, seriously affecting the operational stability of the transportation system.

[0004] Therefore, to address the aforementioned issues, a coal mine electromechanical transport transmission device can be designed. By adding collection devices to both sides of the belt conveyor, accidentally dropped coal can be collected and periodically and automatically returned to the top of the conveyor belt. This effectively prevents the negative impact of spilled coal on the working environment and equipment operation, while achieving closed-loop recycling of spilled materials, significantly improving the environmental performance and operational reliability of the transport system. Utility Model Content

[0005] To overcome the problem that coal blocks are prone to spillage after being loaded onto the conveyor belt due to factors such as vibration, changes in tilt angle, or uneven material distribution, spilled coal blocks not only cause dust pollution and material waste in the working environment, but also cause a series of adverse effects.

[0006] The technical solution of this utility model is as follows: a coal mine electromechanical transport transmission device, including a frame, a supporting mechanism, a driving mechanism, a conveyor belt, and a mounting box. The supporting mechanism is located inside the frame, the driving mechanism is located at the end of the frame, and the conveyor belt is arranged around the periphery of the supporting mechanism and the driving mechanism. Two sets of mounting boxes are provided, and the two sets of mounting boxes are respectively located on both sides of the frame. Multiple sets of collection buckets are slidably connected inside the mounting box. A first wedge is fixedly installed at the lower end of the collection bucket. A set of second wedges is slidably connected inside the mounting box. The wedge surfaces of the second wedges and the first wedges are matched. A second motor is fixedly installed at one end of the mounting box. A reciprocating screw is fixedly installed at the output end of the second motor. The reciprocating screw is rotatably connected to the mounting box. The reciprocating screw passes through the second wedge and is threadedly connected to it.

[0007] Preferably, by setting up a support mechanism in conjunction with a drive mechanism, the conveyor belt can be loaded inside the frame. At the same time, the drive mechanism can drive the conveyor belt to run. Multiple sets of collection buckets are installed by setting up mounting boxes. When the conveyor belt is performing the task of conveying coal, the collection buckets in the mounting boxes on both sides can intercept and collect the scattered coal pieces overflowing from both sides of the conveyor belt in real time. The second motor drives the reciprocating screw to rotate, and the screw drive drives the second wedge to reciprocate linearly, thereby contacting the multiple sets of first wedges inside the mounting box one by one. When the wedge-shaped surface of the second wedge contacts the first wedge, the horizontal motion is converted into the vertical lifting motion of the collection bucket through the inclined plane transmission. During the rising process of the collection bucket, the coal pieces collected inside it automatically fall back to the surface of the conveyor belt under the action of gravity, realizing the closed-loop recycling of scattered materials. When the second wedge leaves, the collection bucket falls back under the action of gravity to continue collecting scattered coal pieces.

[0008] Preferably, the bottom surface inside the collection hopper is a sloping structure, with the bottom end of the sloping surface facing the conveyor belt.

[0009] Preferably, a maintenance baffle is provided on one side of the mounting box, and the maintenance baffle is connected and fixed to the mounting box by bolts.

[0010] Preferably, the support mechanism includes a mounting bracket and a set of idlers. The mounting bracket is fixedly installed inside the frame, and multiple sets of idlers are fixedly installed on the upper end of the mounting bracket. The multiple sets of idlers are evenly and linearly arranged.

[0011] Preferably, the surface of the transport belt has multiple sets of raised anti-slip patterns.

[0012] Preferably, the drive mechanism includes a first drive roller and a first motor. The first drive roller is rotatably connected to one end of the frame, and the first motor is fixedly installed on one side of the frame. The output end of the first motor is fixedly connected to the first drive roller.

[0013] Preferably, the drive assembly includes a second drive roller, a slider, and a linear actuator. The second drive roller is located at the other end of the frame, and sliders are rotatably connected to both ends of the second drive roller. The sliders are slidably connected to the frame, and a set of linear actuators are fixedly installed on both sides of the frame. The output end of the linear actuator is fixedly connected to the slider.

[0014] The beneficial effects of this utility model are:

[0015] During coal transportation, the anti-slip texture on the conveyor belt surface effectively increases the contact friction coefficient between the conveyor belt and the coal, significantly improving material conveying stability and suppressing the slippage and detachment of coal during transportation. Simultaneously, the collection hoppers installed on both sides of the mounting box can intercept and collect scattered coal pieces overflowing from both sides of the conveyor belt in real time. A second motor drives a reciprocating screw to rotate, which in turn drives a second wedge to reciprocate linearly, contacting multiple sets of first wedges inside the mounting box one by one. When the wedge-shaped surface of the second wedge contacts the first wedge, the horizontal motion is converted into the vertical lifting motion of the collection hopper through inclined plane transmission. During the upward movement of the collection hopper, the collected coal pieces automatically fall back to the conveyor belt surface under gravity, achieving closed-loop recycling of scattered materials. After the second wedge leaves, the collection hopper falls back under gravity to continue collecting scattered coal pieces, thus periodically and automatically returning the collected coal pieces to the top of the conveyor belt, effectively preventing the negative impact of spilled coal pieces on the working environment and equipment operation.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment: a coal mine electromechanical transport transmission device, including a frame 1, a supporting mechanism, a driving mechanism, a conveyor belt 5, and a mounting box 6. The supporting mechanism is disposed inside the frame 1, the driving mechanism is disposed at the end of the frame 1, the conveyor belt 5 is disposed around the periphery of the supporting mechanism and the driving mechanism, two sets of mounting boxes 6 are provided, the two sets of mounting boxes 6 are respectively disposed on both sides of the frame 1, and multiple sets of collection buckets 601 are slidably connected inside the mounting box 6, the lower end of the collection bucket 601 is fixedly installed with a first A first wedge 602 is mounted on the first wedge 602. A second wedge 605 is slidably connected inside the mounting box 6. The wedge surfaces of the second wedge 605 match those of the first wedge 602. A second motor 603 is fixedly mounted on one end of the mounting box 6. A reciprocating screw 604 is fixedly mounted on the output end of the second motor 603. The reciprocating screw 604 is rotatably connected to the mounting box 6. The reciprocating screw 604 passes through the second wedge 605 and is threadedly connected to it. The bottom surface inside the collecting hopper 601 is a sloped structure, with the bottom end of the slope facing the conveyor belt 5. (The last sentence appears to be incomplete and possibly refers to a different design.) The supporting mechanism, in conjunction with the drive mechanism, can load the conveyor belt 5 inside the frame 1. Simultaneously, the drive mechanism can drive the conveyor belt 5. Multiple collection hoppers 601 are installed in the mounting boxes 6. When the conveyor belt 5 is conveying coal, the collection hoppers 601 inside the mounting boxes 6 on both sides can intercept and collect any loose coal spilling from both sides of the conveyor belt 5 in real time. The second motor 603 drives the reciprocating screw 604 to rotate, which in turn drives the second wedge 605 to reciprocate linearly via a threaded transmission. This allows the second wedge 605 to contact the first wedge 602 inside the mounting box 6 one by one. When the wedge-shaped surface of the second wedge 605 contacts the first wedge 602, the horizontal motion is converted into the vertical lifting motion of the collecting bucket 601 through the inclined plane transmission. During the rising process of the collecting bucket 601, the coal blocks collected inside it automatically fall back to the surface of the conveyor belt 5 under the action of gravity, realizing the closed-loop recycling of scattered materials. After the second wedge 605 leaves, the collecting bucket 601 falls back under the action of gravity to continue collecting the scattered coal blocks.

[0024] Please see Figure 1 and Figure 2In this embodiment, a maintenance baffle 7 is provided on one side of the mounting box 6. The maintenance baffle 7 is connected and fixed to the mounting box 6 by bolts. The maintenance baffle 7 facilitates the maintenance of the interior of the mounting box 6. The supporting mechanism includes a mounting bracket 201 and a roller group 202. The mounting bracket 201 is fixedly installed inside the frame 1. Multiple roller groups 202 are fixedly installed on the upper end of the mounting bracket 201. The roller groups 202 are evenly and linearly arranged. The mounting bracket 201 supports the roller group 202. The roller group 202 can provide a bearing and guiding effect for the conveyor belt 5, and effectively suppress the lateral deviation of the conveyor belt 5 during operation. Multiple sets of raised anti-slip patterns 501 are provided on the surface of the conveyor belt 5. The anti-slip patterns 501 can effectively increase the contact friction coefficient between the conveyor belt 5 and the coal, significantly improve the material conveying stability, and suppress the slippage and fall of the coal during transportation.

[0025] Please see Figure 2 and Figure 3 In this embodiment, the driving mechanism includes a first driving roller 3 and a first motor 301. The first driving roller 3 is rotatably connected to one end of the frame 1, and the first motor 301 is fixedly installed on one side of the frame 1. The output end of the first motor 301 is fixedly connected to the first driving roller 3. The driving assembly includes a second driving roller 4, a slider 401, and a linear actuator 402. The second driving roller 4 is located at the other end of the frame 1. The two ends of the second driving roller 4 are rotatably connected to the slider 401, which is slidably connected to the frame 1. A set of linear actuators 402 are fixedly installed on both sides of the frame 1, and the output end of the linear actuator 402 is fixedly connected to the slider 401. By setting the first motor 301 to drive the first driving roller 3 to rotate, the conveyor belt 5 is circulated in conjunction with the second driving roller 4. At the same time, the linear actuator 402 pushes the slider 401 to slide linearly along the frame 1, thereby dynamically adjusting the tension of the conveyor belt 5 through the second driving roller 4.

[0026] During operation, the mounting bracket 201 supports and installs the idler roller group 202. Multiple idler roller groups 202 can provide load-bearing guidance for the conveyor belt 5 and effectively suppress lateral deviation of the conveyor belt 5 during operation. Then, the linear actuator 402 pushes the slider 401 to slide linearly along the frame 1, thereby dynamically adjusting the tension of the conveyor belt 5 through the second drive roller 4. The first motor 301 drives the first drive roller 3 to rotate, which, together with the second drive roller 4, realizes the cyclic operation of the conveyor belt 5 and realizes the transportation of coal blocks.

[0027] During coal transportation, the anti-slip texture 501 on the surface of the conveyor belt 5 can effectively increase the contact friction coefficient between the conveyor belt 5 and the coal, significantly improve the stability of material conveying, and suppress the slippage and fall of coal during transportation. At the same time, the collection bucket 601 inside the double-sided mounting box 6 can intercept and collect the scattered coal overflowing from both sides of the conveyor belt 5 in real time. The second motor 603 drives the reciprocating screw 604 to rotate, and the screw drive drives the second wedge 605 to reciprocate linearly, thereby contacting the multiple sets of first wedges 602 inside the mounting box 6 one by one. When the wedge-shaped surface of the second wedge 605 contacts the first wedge 602, the horizontal movement is converted into the vertical lifting and lowering movement of the collection bucket 601 through the inclined plane transmission. During the rising process of the collection bucket 601, the coal collected inside it automatically falls back to the surface of the conveyor belt 5 under the action of gravity, realizing the closed-loop recycling of scattered materials. When the second wedge 605 leaves, the collection bucket 601 falls back under the action of gravity to continue collecting scattered coal.

[0028] The maintenance baffle 7, which is bolted to one side of the mounting box 6, enables efficient maintenance of the internal components of the mounting box 6, significantly improving equipment operability and maintenance efficiency.

[0029] Through the above steps, the collecting hopper 601 can intercept and collect the loose coal chunks overflowing from both sides of the conveyor belt 5 in real time. The second motor 603 drives the reciprocating screw 604 to rotate, thereby driving the second wedge block 605 to reciprocate linearly. When the wedge-shaped surface of the second wedge block 605 contacts the first wedge block 602, the horizontal motion is converted into the vertical lifting motion of the collecting hopper 601 through the inclined plane transmission. During the rising process of the collecting hopper 601, the coal chunks collected inside it automatically fall back to the surface of the conveyor belt 5 under the action of gravity, realizing the closed-loop recycling of loose materials. This solves the problem that when coal chunks are loaded onto the conveyor belt, they are prone to spillage due to factors such as vibration, changes in inclination angle, or uneven material distribution. Spilled coal chunks not only cause dust pollution and material waste in the working environment, but also cause a series of adverse effects.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
