[0002] A mine motor is a driving device used in mining areas. Due to the large amount of dust in mining areas, a dust-proof device is generally covered on the surface of the motor. However, the air circulation of the dust-proof device is poor, which easily causes the motor to overheat and be damaged.

[0003] After retrieval, the Chinese patent discloses a mine motor housing with a dynamic dust-proof structure (publication number: CN214228016U). The housing of this patented technology can be simply and conveniently installed and fixed through a fixing mechanism, and can dynamically prevent dust. At the same time, a heat dissipation mechanism is provided to dissipate the heat generated during the operation of the motor, avoiding high-temperature burning. However, in the technical solution of the above patent document, the overall air circulation of the dust-proof housing is poor, and the air circulation through only a certain number of air vents is insufficient. At the same time, dust is likely to enter when the fan at the air vent does not start, affecting the service life of the motor.

[0004] Therefore, a mine motor with a dust-proof function is proposed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a mine motor with a dust-proof function to solve the above problems, improving the poor air circulation of the overall dust-proof housing, the insufficient air circulation through only a certain number of air vents, and the problem that dust is likely to enter when the fan at the air vent does not start, affecting the service life of the motor.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-5 shown, a mining motor with a dust-proof function includes: a mining electric motor 1, an isolation screen 2 is fixedly connected to the surface of the mining electric motor 1, a screen cage 3 is fixedly connected to the surface of the screen cage 3, and an air outlet 4 is fixedly connected to the side end of the screen cage 3; a circulating exhaust mechanism 5 for exhausting the air inside the isolation screen 2 to take away heat is arranged on one side of the air outlet 4; an internal heat dissipation component 6 for directly dissipating heat from the mining electric motor 1 is arranged on one side of the mining electric motor 1; among them, the circulating exhaust mechanism 5 includes an air extraction component 501 arranged on one side of the air outlet 4, a check component 502 is arranged on one side of the air extraction component 501, both ends of the screen cage 3 are metal plates and are connected to the mining electric motor 1 by bolts, the two metal plates are connected by metal strips, and the surface is covered with an isolation screen 2. For those skilled in the art, the isolation screen 2 is prior art and will not be elaborated here.

[0024] As Figure 3 and Figure 4As shown in the figure, the air extraction assembly 501 includes a connecting pipe 5011 fixedly connected to the circumferential surface of the air outlet 4. A metal sleeve 5013 is fixedly connected to the surface of the connecting pipe 5011. One end of the metal sleeve 5013 is fixedly connected to an air extraction fan 5012. When it is necessary to dissipate heat inside the isolation screen 2, the air extraction fan 5012 is started at this time. The air extraction fan 5012 extracts the air inside the metal sleeve 5013 and the air outlet 4. At this time, new air is drawn in through the holes of the isolation screen 2, and the air circulates. During the circulation process, the air takes away heat. The inside of the air extraction fan 5012 is a scroll fan blade that can push the air to flow. For those skilled in the art, the air extraction fan 5012 is a prior art and will not be elaborated here. The check valve assembly 502 includes a positioning protrusion 5022 fixedly connected to the inner wall of the metal sleeve 5013. A blocking plate 5021 is rotatably connected to the circumferential inner wall of the metal sleeve 5013. One side of the positioning protrusion 5022 is in contact with the blocking plate 5021. When the air extraction fan 5012 of this device is not started, dust easily enters the air outlet 4 and the isolation screen 2 along with the air and accumulates on the surface of the mine electric motor 1. At this time, the blocking plate 5021 drops due to gravity and fits on the surface of the positioning protrusion 5022, and the blocking plate 5021 closes to prevent dust from entering. When extracting air, the air pushes the blocking plate 5021 to rise and the air enters.

[0025] As Figure 5 shown in the figure, the internal heat dissipation assembly 6 includes a fitting seat 601 fixedly connected to the inner wall of the mine electric motor 1. A self-rotating roller shaft 603 is fixedly connected to the side end of the fitting seat 601. Heat dissipation fan blades 602 are fixedly connected to the surface of the self-rotating roller shaft 603. The fitting seat 601 fits inside the mine electric motor 1. At the same time, the fitting seat 601 has fast heat conduction. The self-rotating roller shaft 603 pushes the heat dissipation fan blades 602 to rotate and take away heat. The self-rotating roller shaft 603 can rotate itself to transmit power to drive the heat dissipation fan blades 602 to rotate. At this time, the temperature reduction of the fitting seat 601 can reduce the temperature inside the mine electric motor 1. For those skilled in the art, the self-rotating roller shaft 603 is a prior art and will not be elaborated here. A rubber gasket 606 is fixedly connected to the inner wall of the screen cage 3. The inner wall of the rubber gasket 606 is in interference fit with the fitting seat 601. Through the rubber gasket 606, the fitting seat 601 can be sealed with the inner wall of the screen cage 3 to prevent dust from entering and causing equipment damage. A blocking frame 604 is slidably connected to the inner wall of the screen cage 3. The blocking frame 604 is detachably connected to the self-rotating roller shaft 603 through a bolt. The heat dissipation fan blades 602 can be blocked by the blocking frame 604 to prevent damage caused by contact and collision. A threaded column 605 is fixedly connected to the side end of the mine electric motor 1. The threaded column 605 movably penetrates the side ends of the screen cage 3 and the blocking frame 604 and extends outward. The blocking frame 604 can be detachably connected to the mine electric motor 1 through the threaded column 605, so that the blocking frame 604 is not easy to shake and skew after installation.

[0026] When the utility model is in use, when the rotational power output is carried out through this device, the mine electric motor 1 can be started to output rotational power. When heat dissipation is required inside the isolation screen 2, the air extraction fan 5012 is started at this time. The air extraction fan 5012 extracts the air inside the metal sleeve 5013 and the air outlet 4. At this time, new air is drawn in from the holes of the isolation screen 2, and the air circulates. During the circulation process, the air takes away heat. At the same time, the self-rotating roller shaft 603 is started to rotate, and the self-rotating roller shaft 603 drives the heat dissipation fan blades 602 to rotate, so that the air cools down and takes away the heat on one side of the fitting seat 601, reducing the temperature of the mine electric motor 1 and ensuring heat dissipation while isolating dust.

[0027] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
