The permanent magnet motor housing assembly has the advantage of being easy to maintain.

[0004] Although the prior art CN212258600U has many benefits during use, it still has the following problems: it lacks a cleaning structure for the heat dissipation fins of the motor, which causes dust adhering to the outer wall of the heat dissipation fins to affect its heat dissipation efficiency. Utility Model Content

[0005] The utility model aims to provide a coal mill tail discharge motor housing assembly to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coal mill tail discharge motor housing assembly, comprising a motor body, a connecting ring, a fixed block and a slider, the outer wall of the motor body is installed with heat dissipation fins distributed in a circular array, the outer wall of the motor body on the side away from the heat dissipation fins is installed with a fixed block, electric push rods are installed on the outer walls of both sides of the fixed block, a connecting ring is installed on the outer wall of one end of the electric push rod, sliding grooves are provided on both sides of the inner wall of the connecting ring, a slider distributed in a circular array is slidably installed inside the sliding groove, and a screw hole is provided on the outer wall of one side of the slider.

[0007] When using a coal mill tail discharge motor housing assembly in the present technical solution, the staff moves the slider to ensure that the scraper is located between the cooling fins, and the staff manually turns the bolts to ensure the position stability of the slider and the scraper. The electric push rod drives the connecting ring to move horizontally, thereby moving the connecting ring outside the motor body. The scraper contacts the outer wall of the cooling fin, causing the dust on the outer wall of the cooling fin to fall off.

[0008] Preferably, the outer wall of the motor body is provided with base bodies distributed in a rectangular array, and the base bodies are designed in an L-shape. The motor body can be fixed by the base body.

[0009] Preferably, the connecting ring is designed in a circular ring shape and is located outside the motor body.

[0010] Preferably, a scraper is installed on the outer wall of one side of the sliding block, and the scraper is located between the heat dissipation fins. The scraper can clean the outer wall of the heat dissipation fins.

[0011] Preferably, a bolt is threadedly connected inside the screw hole, and the bolt contacts the outer wall of the connecting ring. The extrusion force between the bolt and the connecting ring ensures the position stability of the slider inside the slide groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model achieves the effect of cleaning the cooling fins by arranging an electric push rod, a slider and a scraper. The staff moves the slider to ensure that the scraper is located between the cooling fins, and the staff manually rotates the bolt to ensure the position stability of the slider and the scraper. The electric push rod drives the connecting ring to move horizontally, thereby moving the connecting ring outside the motor body. The scraper contacts the outer wall of the cooling fin, so that the dust on the outer wall of the cooling fin falls off, thereby ensuring the cleanliness of the outer wall of the cooling fin and the cooling efficiency of the cooling fin.
