Technical Field

[0001] The utility model belongs to the technical field of solid material transportation and relates to an automatic dredging coal conveying device system. Background Art

[0002] Currently, the on-site transportation of solid materials, especially coal within mines, is primarily based on belts and vertical pipelines. However, due to the inconsistent shapes and sizes of solid materials, arching and blockages can easily occur during transportation. Existing transportation systems primarily identify blockages manually by observing phenomena such as material squeezing, piling, spilling, and prolonged periods of no material discharge at the inlet. This leads to late detection, wasted material spillage, and significant damage to equipment, seriously impacting effective transportation. Furthermore, once a large pipeline becomes clogged, manual unblocking is difficult and time-consuming, significantly impacting production and even hindering operations.

[0003] Therefore, how to detect blockage more reliably and accurately and achieve rapid unblocking is an urgent problem to be solved. Utility Model Content

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] In a specific embodiment, the present invention provides an automatic dredging coal conveying device system, such as Figure 1 As shown, it includes a high-level coal bunker 1, a coal feeding device 2, a blanking device 3 and a conveying device 4 that are connected in sequence. The blanking device 3 includes a receiving hopper 31 and a blanking pipe that are interconnected. The receiving hopper 31 is connected to the coal feeding device 2, and the inlet end of the receiving hopper 31 is also provided with an arch-breaking device 5. The blanking device 3 is externally connected to a coal blockage monitoring device, and the coal blockage monitoring device includes an electrically connected detection component 6 and a control terminal 7. The detection component 6 is provided on the blanking pipe, and the control terminal 7 is electrically connected to the coal feeding device 2, the conveying device 4 and the arch-breaking device 5 respectively. During use, the detection component 6 is used to perform real-time online monitoring of the working status of the blanking pipe. Once a blockage is found, the control terminal 7 automatically controls the coal feeding device 2 and the conveying device 4 to stop transportation, and at the same time controls the arch-breaking device 5 to automatically clear the blockage.

[0030] In some embodiments, the outlet end of the high-position coal bunker 1 is provided with an activation vibration component for activating and vibrating the coal at the outlet end of the high-position coal bunker 1, so that the coal has better fluidity while falling by its own gravity.

[0031] In some embodiments, the coal feeding device 2 includes a first drive motor 201 and a feeding assembly 202 that are transmission-connected. The first drive motor 201 is used to drive the feeding assembly 202 to feed, and the feeding assembly 202 delivers the coal from the high-level coal bunker 1 into the receiving hopper 31. The first drive motor 201 is also electrically connected to the control terminal 7. The control terminal 7 can remotely control the start and stop of the first drive motor 201 through common software and hardware and electromechanical control technology in the field, so as to control the feeding assembly 202 to stop feeding when a blockage occurs. The feeding assembly 202 can adopt the horizontal feeding method commonly used in the field, and can select a reciprocating feeding assembly 202, a scraper feeding assembly 202, or a belt feeding assembly 202. The present invention does not make specific restrictions on this, and those skilled in the art can make adjustments according to actual conditions.

[0032] In some embodiments, the conveying device 4 includes a second drive motor 401 and a conveyor belt 402 in a transmission connection. The second drive motor 401 is used to drive the conveyor belt 402 to transport coal. One end of the conveyor belt 402 is set at the outlet end of the drop device 3 to transport the coal to the target area. The second drive motor 401 is also electrically connected to the control terminal 7. The control terminal 7 can remotely control the start and stop of the second drive motor 401 through common software and hardware and electromechanical control technology in the field, so as to control the conveyor belt 402 to stop transportation when a blockage occurs. The conveyor belt 402 can adopt a horizontal conveyor belt 402, an inclined conveyor belt 402 or a combined conveyor belt 402 commonly used in the field. The present invention does not make specific restrictions on this, and those skilled in the art can make adjustments according to actual conditions.

[0033] In some embodiments, the arch-breaking device 5 includes a third drive motor 501 and an arch-breaking body 502 connected in a transmission manner. The third drive motor 501 is used to drive the arch-breaking body 502 to break and dredge the material-bearing device 3. The third drive motor 501 is also electrically connected to the control terminal 7. The control terminal 7 can remotely control the start and stop of the third drive motor 501 through common software and hardware and electromechanical control technology in this field, thereby controlling the arch-breaking body 502 to extend into the interior of the material-bearing pipe for dredging, and reset after the coal-breaking and dredging is completed. The present utility model does not specifically limit the structure of the arch-breaking body 502, and can adopt any one of the rotating cone type, spiral type, scraper type, and vibration type known to those skilled in the art, or a combination of at least two.

[0034] In addition, the high-level coal bunker 1, coal feeding device 2, conveying device 4 and arch breaking device 5 in the utility model are also provided with necessary connecting pipelines and switch control valves. The utility model does not make special restrictions on this. Technical personnel in this field need to reasonably adjust, add or delete according to actual production needs. It should be clear that new technical solutions generated by deleting some unnecessary connecting pipelines and switch control valves, or replacing single-function switch control valves with multi-function integrated control valves, or using an automatic control system in which an external device is electrically connected to the switch control valve to control the opening of the corresponding valve, etc., which are common and well-known conventional technical means for technical personnel in this field, also fall within the scope of disclosure and protection of the utility model.

[0035] In some embodiments, the material discharge pipe includes a vertical main section 301 and an inclined material discharge section 302 connected in sequence, the vertical main section 301 is connected to the receiving hopper 31, the inclined material discharge section 302 is connected to the conveyor belt 402, and the detection component 6 is arranged in the vertical main section 301.

[0036] Furthermore, a removable anti-sticking guide block 303 is installed at the junction of the vertical main section 301 and the inclined discharge section 302. Made of a flexible material, this allows coal from the vertical main section 301 to be discharged directly from the inclined discharge section 302, preventing it from adhering to the inner wall of the pipe and causing further blockage. The anti-sticking guide block 303 can be securely fixed to the junction of the vertical main section 301 and the inclined discharge section 302 via bolts, snap-fit ​​connections, or adhesive bonding. The end that contacts the coal can have a tapered tip to ensure smooth passage of the coal.

[0037] Preferably, the outer wall of the inclined discharge section 302 is further provided with a rapper 304 for rapping the coal in the inclined discharge section 302 so that it falls onto the conveyor belt 402 to avoid material blockage. The rapper 304 can be an ultrasonic vibrator or an electromagnetic rapper 304 well known to those skilled in the art.

[0038] Furthermore, protective layers are provided on the inner walls of both the vertical main section 301 and the inclined feed section 302. Specifically, the protective layers include a wear-resistant layer and a smooth layer sequentially coated on the inner wall of the pipe. The smooth layer is less likely to adhere to the coal, preventing it from clogging the pipe, while the wear-resistant layer prevents the coal from damaging the inner wall of the equipment.

[0039] In some embodiments, the detection component 6 is any one of a photoelectric sensor, a limit switch, a proximity switch, and an eddy current sensor. When the detection component 6 is a photoelectric sensor, it necessarily includes a transmitter and a receiver, which are well known to those skilled in the art. When there is no coal blockage in the drop pipe, the receiver can receive the light signal emitted by the light transmitter. However, when a coal blockage occurs in the drop pipe, the light signal between the receiver and the transmitter is altered by the coal, and the receiver cannot receive the predetermined amount of light, thereby outputting a blockage signal. When the detection component 6 is a limit switch, in actual use, the position where the coal first falls out of the drop pipe when a blockage occurs without other interference is first determined. A limit switch is then set at this position. A contact piece is set on the lever of the limit switch to withstand the impact of falling coal. When a large area of ​​coal blockage occurs, the contact piece will be impacted. When the limit switch detects the collision, the normally open contact closes, thereby outputting a blockage signal. When the detection component 6 is a proximity switch, it necessarily includes a metal block for triggering the proximity switch, as is well known to those skilled in the art. Under normal conditions, the coal does not squeeze the metal block, and the metal block remains in the proximity switch-untriggered state. However, when a coal blockage occurs within the feeding pipe, the coal exerts a squeezing force on the metal block, causing it to move outward. This triggers the proximity switch, which outputs a signal indicating a blockage. When the detection component 6 is an eddy current sensor, it utilizes the principle of electromagnetic induction to detect blockage by measuring changes in induced eddy currents within the feeding pipe. Typically, an eddy current probe, commonly used by those skilled in the art, is inserted into the feeding pipe for real-time monitoring.

[0040] In some embodiments, the control terminal 7, which serves as a terminal for staff to operate and monitor, may include a general-purpose host computer or host computer. Based on the signal output by the detection component 6, it can promptly stop the operation of the corresponding equipment and initiate automatic unblocking to prevent further material blockage. The control terminal 7 is also equipped with an alarm, which is electrically connected to the detection component 6. During use, if the detection component 6 detects a blockage in the material delivery pipe, it can trigger the alarm to alert staff. The alarm can specifically adopt an audible and visual alarm commonly used by those skilled in the art.

[0041] The utility model temporarily stores the coal in the mine into a high-level coal bunker 1. When it needs to be transported, the coal in the high-level coal bunker 1 falls onto the coal feeding device and is transported into the dropping device 3. The coal dropped by the dropping device 3 is then transported to the target area through the conveying device 4. An arch-breaking device 5 is provided on the top of the dropping device 3. When there is a coal arch blockage or partial blockage in the dropping pipe, resulting in a reduction in the dropping of coal, it is detected by a detection component 6 provided on the dropping pipe. The detection component 6 dynamically transmits a signal to the control terminal 7. The control terminal 7 will close the coal feeding device and the conveying device 4 according to the received signal, and start the arch-breaking device 5 for clearing the blockage. When the arch-breaking device 5 has cleared the blockage, it will be reset to start the transportation or manually started after confirmation by the system monitoring.

[0042] The applicant declares that the above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Technicians in the relevant technical field should understand that any changes or substitutions that can be easily thought of by technicians in the relevant technical field within the technical scope disclosed in the present invention fall within the protection scope and disclosure scope of the present invention.
