[0037] Please refer to the attached Figure 2 、 4As shown in Figures 6 and 7, in another preferred embodiment of the present invention, the peristaltic coal-draining device 20 includes a plurality of annular air bags 21 arranged in sequence from top to bottom on the inner wall of the coal bunker 10, a protective component 22 arranged on the outer wall of the annular air bag 21, a pressure-controlled gas supply component 23 arranged on the outer wall of the coal bunker 10 and used to supply pressurized gas to the annular air bag 21, and an air pressure source component 25 arranged on the top of the annular top plate 11 and connected to the air supply pipeline 24 at its execution end. A temperature regulating component 26 and a flow rate detecting component 27 are arranged in sequence on the outer wall of the air supply pipeline 24 and between the air pressure source component 25 and the pressure-controlled gas supply component 23. Each of the annular air bags 21 has a corresponding pressure-controlled gas supply component 23, and the gas supply pipeline 24 is used to supply pressurized air to a plurality of pressure-controlled gas supply components 23. The pressure-controlled gas supply component 23 includes a first solenoid valve 231 arranged on the outer wall of the coal bunker 10 and connected to the annular air bag 21 through a pipeline, and a pressure-controlled gas supply component 25 arranged on the annular air bag 21.

[0038] It should be noted that, in this embodiment, when the peristaltic coal diversion device 20 is in operation, the air pressure source component 25 introduces pressurized gas into the gas pipeline 24, and the plurality of pressure-controlled gas supply components 23 facilitate pressure-controlled gas supply to the plurality of annular airbags 21 in a top-down order, so that the plurality of annular airbags 21 form a wave-like contraction, thereby peristaltically moving the coal in the coal bunker 10 downward. The stainless steel plate 221 facilitates protecting the annular airbags 21.

[0039] Furthermore, when the pressure-controlled gas delivery component 23 is working, the topmost first solenoid valve 231 is opened. When the measured value of the air pressure sensor 232 corresponding to the topmost first solenoid valve 231 reaches half of the set value, the PLC controller opens the first solenoid valve 231 adjacent below. When the measured value of the air pressure sensor 232 corresponding to the topmost first solenoid valve 231 reaches the set value, the PLC controller closes the topmost first solenoid valve 231, so that the top first solenoid valve 231 stops taking in air, and the gas in the top annular airbag 21 is discharged through the top first solenoid valve 231, completing expansion and contraction.

[0040] Furthermore, when the air pressure source component 25 is working, the air compressor 252 compresses the air and discharges it into the air tank 251, and the air tank 251 discharges the compressed gas into the air pipeline 24;

[0041] Furthermore, the temperature regulating component 26 is convenient for regulating the temperature of the gas source to prevent condensation on the surface of the annular airbag 21 due to low gas source temperature. During temperature regulation, the PLC controller receives temperature data from the temperature sensor 263 and triggers the spiral heating tube 262 until the temperature data reaches the set value.

[0042] Furthermore, the PLC controller receives flow data from the flow sensor 271 and triggers the air compressor 252 until the flow data reaches a set value. The faster the compressed gas flow rate, the shorter the time it takes for the annular airbag 21 to complete an expansion and contraction, and the higher the peristaltic frequency.

[0043] Please refer to the attached Figure 2 、 3 , 5, 7, and 8, in another preferred embodiment of the present invention, the auxiliary coal discharging device 30 includes a vibration rod 32 connected to the annular top plate 11 through multiple support plates 31 on the top of the side wall, a rapping component 33 provided on the support plate 31, and an air bag support component 34 and a vibration diffusion component 35 provided on the side wall of the vibration rod 32, the rapping component 33 includes a striking tube 331 provided on the top of the vibration rod 32, and an air hammer 332 provided on the top of the support plate 31, the air bag support component 34 includes a sleeve provided on the vibration There are multiple columnar airbags 341 on the outer wall of the rod 32 and connected to each other, one of the columnar airbags 341 is connected to the second solenoid valve 342 located on the outer wall of the gas tank 251 through a pipe, and the second solenoid valve 342 is connected to the gas tank 251 through a pipe. The multiple columnar airbags 341 are equidistantly distributed on the side wall of the vibration rod 32 from top to bottom, and the vibration diffusion component 35 includes multiple vibration transmission rods 351 arranged in sequence from top to bottom on the side wall of the vibration rod 32, and the vibration transmission rods 351 and the columnar airbags 341 are staggered and distributed on the side wall of the vibration rod 32.

[0044] It should be noted that, in this embodiment, when the airbag support component 34 is working, the second solenoid valve 342 is opened, and pressurized gas enters the cylindrical airbag 341 to expand the cylindrical airbag 341. The air pressure in the cylindrical airbag 341 is constant, and the cylindrical airbag 341 will expand and contract in coordination with the expansion and contraction of the annular airbag 21 to assist peristalsis.

[0045] Furthermore, the execution end of the air hammer 332 can strike the striking tube 331, and the striking tube 331 drives the vibration rod 32 to vibrate, and the vibration rod 32 drives the vibration transmission rod 351 to vibrate. Both the vibration rod 32 and the vibration transmission rod 351 can vibrate and loosen the coal in the coal bin 10.

[0046] The specific process of the present invention is as follows:

[0047] The PLC controller model is "PR20", the infrared sensor 122 model is "XLM12D10FV", the air pressure sensor 232 model is "LFT2000", the temperature sensor 263 model is "OHR-214", and the flow sensor 271 model is "AKLUGB".

[0048] When the coal bunker 10 is blocked, the infrared sensor 122 transmits information that there is no coal leakage to the PLC controller, and the PLC controller triggers the peristaltic coal diversion device 20 and the auxiliary coal diversion device 30 to work;

[0049] When the peristaltic coal-draining device 20 is in operation, the air pressure source component 25 introduces pressurized gas into the gas pipeline 24. The multiple pressure-controlled gas supply components 23 facilitate pressure-controlled gas supply to the multiple annular airbags 21 in a top-down order, so that the multiple annular airbags 21 form a wave-like contraction, thereby peristaltically moving the coal in the coal bunker 10 downward. The stainless steel plate 221 facilitates protecting the annular airbags 21.

[0050] When the pressure-controlled gas delivery component 23 is working, the topmost first solenoid valve 231 is opened. When the measured value of the air pressure sensor 232 corresponding to the topmost first solenoid valve 231 reaches half of the set value, the PLC controller opens the first solenoid valve 231 adjacent below. When the measured value of the air pressure sensor 232 corresponding to the topmost first solenoid valve 231 reaches the set value, the PLC controller closes the topmost first solenoid valve 231, so that the top first solenoid valve 231 stops taking in air, and the gas in the top annular airbag 21 is discharged through the top first solenoid valve 231, completing expansion and contraction.

[0051] When the air pressure source component 25 is working, the air compressor 252 compresses the air and discharges it into the air tank 251, and the air tank 251 discharges the compressed gas into the air pipeline 24;

[0052] The temperature regulating component 26 is convenient for regulating the temperature of the gas source to prevent condensation on the surface of the annular airbag 21 due to low gas source temperature. During temperature regulation, the PLC controller receives temperature data from the temperature sensor 263 and triggers the spiral heating tube 262 until the temperature data reaches the set value.

[0053] The PLC controller receives the flow data from the flow sensor 271 and triggers the air compressor 252 until the flow data reaches the set value. The faster the compressed gas flow rate, the shorter the time it takes for the annular airbag 21 to complete one expansion and contraction, and the higher the peristaltic frequency.

[0054] When the airbag support component 34 is working, the second solenoid valve 342 is opened, and pressurized gas enters the cylindrical airbag 341 to expand the cylindrical airbag 341. The air pressure in the cylindrical airbag 341 is constant, and it will expand and contract in coordination with the expansion and contraction of the annular airbag 21 to assist peristalsis.

[0055] The execution end of the air hammer 332 can strike the striking tube 331, and the striking tube 331 drives the vibration rod 32 to vibrate, and the vibration rod 32 drives the vibration transmission rod 351 to vibrate. Both the vibration rod 32 and the vibration transmission rod 351 can vibrate and loosen the coal in the coal bunker 10.

[0056] The above description of the present invention is exemplified in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
