Detailed Implementation

[0025] Example 1: As Figs. 1 to 4 As shown, a cooling device for the cutting section of a coal mining machine includes a cutting section body 1. A cutting head 101 is fixedly connected to one side of the cutting section body 1. A cooling component 2 is fixedly connected to one side of the cutting section body 1. The cooling component 2 includes an annular pipe 201. Coolant is transported to each inlet pipe 205 through the annular pipe 201. The inside of the annular pipe 201 is fixedly connected to the outside of the cutting section body 1. A connecting shell 202 is fixedly connected to the outside of the annular pipe 201. A cover component 3 is fixedly connected to one side of the cooling component 2. The cover component 3 includes two fixing plates 301. One side of each fixing plate 301 is fixedly connected to one side of the connecting shell 202. A detection component 4 is provided on one side of the cooling component 2.

[0026] A liquid delivery pipe 203 is fixedly connected to one side of the annular pipe 201, and a valve 204 is fixedly connected to one side of the liquid delivery pipe 203. When the operator uses the cooling device, the coolant is delivered to the inlet pipe 205 by opening the valve 204. When the valve 204 is opened, the coolant passes through the liquid delivery pipe 203 to the annular pipe 201, and then the annular pipe 201 delivers the coolant to each inlet pipe 205.

[0027] Several liquid inlet pipes 205 are fixedly connected to one side of the annular pipe 201. The liquid inlet pipes 205 are arranged in a circle. A mist nozzle 206 is fixedly connected to one side of each liquid inlet pipe 205. The liquid inlet pipes 205 deliver coolant to the mist nozzle 206. At this time, the coolant is atomized by the mist nozzle 206 to cool down the cutting head 101 and improve the working efficiency of the cooling device.

[0028] A fixed shell 302 is fixedly connected inside each of the two fixed plates 301. A telescopic rod 303 is inserted into the inside of each of the two fixed shells 302. A connecting plate 304 is fixedly connected to one side of each of the two telescopic rods 303. The telescopic rods 303 extend and retract inside the fixed shells 302, thereby moving the connecting plate 304 to adjust the position of the cover plate 306.

[0029] A connecting rod 305 is fixedly connected to one side of each of the two connecting plates 304, and a cover plate 306 is fixedly connected to one side of each of the two connecting rods 305. The two cover plates 306 are symmetrically distributed. Before the coal mining machine cutting section is working, the operator adjusts the position of the telescopic rod 303, thereby moving the cover plate 306 to expose the mist nozzle 206. At this time, the cover plate 306 will not affect the normal operation of the mist nozzle 206. When the coal mining machine cutting section is not working, the operator adjusts the position of the telescopic rod 303 again, moving the cover plate 306 to cover the mist nozzle 206 to prevent dust and other debris from adhering to the mist nozzle 206.

[0030] The detection component 4 includes a flow sensor 401, an indicator light 402, and an indicator horn 403. The flow sensor 401 is externally and internally fixedly connected to the infusion tube 203. The flow sensor 401 is electrically connected to the indicator light 402 and the indicator horn 403. The flow sensor 401 is a known technology and has not been improved in this utility model, so it will not be described in detail here. The flow sensor 401 can monitor the flow rate and flow of the coolant in real time. When the coolant flow is too low, it indicates that the coolant supply is insufficient. At this time, the flow sensor 401 will transmit a signal.

[0031] One side of the reminder light 402 is fixedly connected to one side of the connecting shell 202, and one side of the reminder horn 403 is fixedly connected to one side of the connecting shell 202. When the coolant supply is insufficient, the reminder light 402 lights up red and the reminder horn 403 emits a beeping sound to remind the operator, so that the operator can check and adjust the coolant supply in time to ensure that the cutting part is adequately cooled.

[0032] Example 2: Based on Example 1, a lighting component can be installed to illuminate the cutting area when it is dark, making it easier for operators to observe the work situation and improving the practical performance of the cooling device.

[0033] A cooling device for the cutting section of a coal mining machine, the working principle of which is as follows:

[0034] When using the cooling device of the coal mining machine's cutting section, the operator opens valve 204 to deliver coolant to the inlet pipe 205. When valve 204 is opened, the coolant flows through the delivery pipe 203 to the annular pipe 201, and then the annular pipe 201 delivers the coolant to each inlet pipe 205. The inlet pipe 205 then delivers the coolant to the mist nozzles 206, where the coolant is atomized to cool the cutting head 101, improving the efficiency of the cooling device. Simultaneously, the telescopic rod 303 of the cover assembly 3 extends and retracts inside the fixed housing 302, thereby moving the connecting plate 304 to adjust the position of the cover plate 306. Before the coal mining machine's cutting section begins operation, the operator adjusts the position of the telescopic rod 303, which in turn moves the cover plate 306. Exposing the mist nozzle 206 ensures that the cover plate 306 does not affect its normal operation. When the coal mining machine cutting section is not in operation, the operator can adjust the position of the telescopic rod 303 to move the cover plate 306 and cover the mist nozzle 206, preventing dust and other debris from adhering to it. When the cooling device is working, the flow sensor 401 can monitor the flow rate and volume of the coolant in real time. When the coolant flow rate is too low, it indicates insufficient coolant supply. The flow sensor 401 will then transmit a signal. When the coolant supply is insufficient, the warning light 402 will illuminate red, and the warning horn 403 will emit a beeping sound to remind the operator, allowing them to check and adjust the coolant supply in a timely manner to ensure that the cutting section is adequately cooled.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] A covering component 3 is provided to cover the mist nozzle 206 when the cooling device is not in operation, preventing dust and other debris from adhering to the mist nozzle 206. This solves the problem of dust and other debris adhering to the mist nozzle 206 when the cooling device is not in operation, which affects its service life and improves the practical performance of the cooling device. A detection component 4 is also provided to detect the coolant supply and promptly remind the operator when the coolant supply is insufficient. This solves the problem of the cutting part overheating due to the lack of timely reminders when the coolant supply is insufficient, and improves the safety performance of the cooling device.
