[0002] A motor is an important device that can convert electrical energy and mechanical energy into each other, and is widely used in modern industry and daily life; a motor mainly consists of two major parts: a stator and a rotor. The stator is the fixed part and plays a key role in providing a magnetic field; the rotor is the rotating part and rotates under the action of the magnetic field generated by the stator, thereby outputting mechanical energy; The patent with the application number CN202211090309.5 discloses a motor facilitating disassembly and assembly of the housing, including a motor housing. Disassembly and assembly devices are symmetrically arranged at equal intervals on the top of the motor housing, and a motor rear cover and a motor front cover are respectively arranged on both sides of the disassembly and assembly devices; New energy vehicles require lithium, titanium, and some rare earth elements during the production process. These substances have rich deposits in the desert. When mining minerals in desert areas, motors are used to drive belts to transport materials by conveyors. Existing motors are generally equipped with heat dissipation holes, and the heat generated during the operation of the motor is cooled by air flow. The air in the desert contains a large amount of dust, which will cover the motor, resulting in heat accumulation during the operation of the motor. If the motor cannot dissipate heat for a long time during operation, the motor will burn out and cannot work, affecting the working efficiency of the motor. Summary of the Invention

The left side of the docking short shaft is clamped with the rotating shaft. A collecting sleeve is fixedly connected to the outer wall of the deflection blade on the right side of the second sand guard net.

[0006] Preferably, a control gear disk is movably connected to the outer wall of the collecting sleeve through a bearing. A worm motor is fixedly connected to the outer wall of the collecting sleeve on the right side of the control gear disk. Tooth patterns are arranged on the right side of the control gear disk to cooperate with the worm motor. Tooth patterns are arranged on the outer wall of the collecting sleeve, and tooth patterns are arranged on the left side of the control gear disk to cooperate with the collecting sleeve.

[0007] Preferably, a second sweeping brush is fixedly connected to the outer wall of the collecting sleeve on the right side of the second sand guard net. A first sweeping brush is fixedly connected to the outer wall of the rotating shaft on the left side of the first sand guard net.

[0008] Preferably, the light shock mechanism includes a fixed frame. The fixed frame is arranged at the bottom of the stator housing. A movable plate is movably connected inside the fixed frame. The top of the movable plate is fixedly connected to the bottom of the stator housing. A support spring is fixedly connected to the bottom of the movable plate inside the fixed frame.

[0009] Preferably, a first eccentric block is fixedly connected to the outer wall of the docking short shaft outside the stator housing. A second eccentric block is fixedly connected to the outer wall of the rotating shaft outside the end cover.

[0010] Preferably, an elastic sand guard net is fixedly connected inside the fixed frame. An air inlet plate is arranged on the front surface of the elastic sand guard net on the inner wall of the fixed frame.

[0011] Preferably, a movable piece is movably connected inside the movable plate at the bottom of the end cover. The movable piece is provided with a limiting protrusion. A top spring is fixedly connected to the back surface of the air inlet plate on the front surface of the elastic sand guard net. The elastic sand guard net has elasticity.

[0012] The present invention provides a motor facilitating disassembly and assembly of the housing. It has the following beneficial effects: 1. For the motor facilitating disassembly and assembly of the housing, by making the worm motor and the control gear disk rotate relatively, the deflection angle of the deflection blade is changed, and then the direction of the airflow pushed by the deflection blade is changed, so as to indirectly make the airflow blow from the inside to the outside of the two sand guard nets. Cooperating with the corresponding sweeping brushes, the dust is blown off the surface of the sand guard nets, avoiding blockage of the sand guard nets by sand and gravel, preventing the heat dissipation of the motor from being affected and generating heat accumulation, and ensuring the normal operation of the motor.

[0013] 2. The motor with easily detachable and installable housing drives the rotating shaft to rotate through the rotor, and makes the docking short shaft rotate together, thereby driving the first eccentric block and the second eccentric block to rotate around the same axis, causing the motor to generate slight up-and-down vibrations. As a result, the stator housing will move up and down accordingly to shake off the dust adhering to its surface, preventing excessive dust from adhering to the surface of the stator housing, and further preventing the motor from being damaged due to heat accumulation during operation, thus ensuring the normal operation of the motor.

[0014] 3. When the motor with easily detachable and installable housing vibrates up and down, the first dust-proof net and the second dust-proof net will also vibrate together through the stator housing and the end cover. As a result, the sand stuck inside the small holes of the second dust-proof net and the first dust-proof net will be shaken out, facilitating the second sweeping brush and the first sweeping brush to sweep it away. Furthermore, it can enhance the air circulation and the heat dissipation effect of the air flow, and further prevent the motor from being damaged due to heat accumulation.

[0015] 4. The motor with easily detachable and installable housing drives the movable plate to move up and down. In cooperation, the external air presses open the air inlet plate and enters the fixed frame through the elastic dust-proof net. Then, the gas will push up the movable piece. Since the upward movement range of the movable piece is limited, the gas will blow from the bottom of the moved movable piece to the periphery of the top surface of the movable plate, thereby preventing dust from accumulating near the motor and causing heat accumulation during the operation of the motor, thus ensuring the normal operation of the motor.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0020] Embodiment 1: Please refer to Figures 1-6 , the present invention provides a technical solution: a motor facilitating the disassembly and assembly of the housing, including a stator housing 1, an end cover 2 is fixedly connected to the left side of the stator housing 1, and the end cover 2 is fixedly connected to the stator housing 1 through bolts. The housing of the motor can be separated by screwing the bolts, thereby facilitating the disassembly of the motor. A stator is arranged on the inner wall of the stator housing 1, a rotor 3 is arranged inside the stator housing 1, a rotating shaft 4 is fixedly connected inside the rotor 3, the rotating shaft 4 is movably connected inside the end cover 2, a pulley 5 is fixedly connected to the outer wall of the rotating shaft 4 on the left side of the rotating shaft 4, a heat dissipation mechanism 6 is fixedly connected to the outer wall of the end cover 2, and a light shock mechanism 7 is fixedly connected to the bottom of the stator housing 1; The heat dissipation mechanism 6 includes: The first anti-sand screen 601, and the first anti-sand screen 601 is fixedly connected to the outer wall of the left side of the end cover 2; The second anti-sand screen 602, and the second anti-sand screen 602 is fixedly connected to the outer wall of the right side of the stator housing 1; The deflection blade 604, and the deflection blade 604 is arranged on the right side of the second anti-sand screen 602.

[0021] Connect the outer wall of the pulley 5 to the corresponding transmission belt, and start the motor to work. The rotor 3 will drive the rotating shaft 4 to rotate, and transmit the power to the outside through the pulley 5. The first anti-sand screen 601 and the second anti-sand screen 602 will prevent the floating dust from entering the inside of the motor and interfering with the operation of the motor.

[0022] Inside the stator housing 1, a docking short shaft 609 is movably connected to the right side of the rotating shaft 4. The left side of the docking short shaft 609 is clamped to the rotating shaft 4. On the outer wall of the deflection vane 604, a collecting sleeve 603 is fixedly connected to the right side of the second sand protection net 602. The deflection vane 604 is arranged on the outer wall of the collecting sleeve 603.

[0023] When the rotating shaft 4 is driven by the rotor 3 to rotate, it will drive the docking short shaft 609 to rotate in a clamped manner. When the docking short shaft 609 rotates, it will drive the collecting sleeve 603 on its surface to rotate together, thereby causing the deflection vane 604 to rotate. The rotation of the deflection vane 604 will push the air, allowing the air to pass through the second sand protection net 602 and enter the inside of the stator housing 1 and then discharge from the first sand dispersion protection net 601 to cool the inside of the stator housing 1. When the air passes through the second sand protection net 602, the second sand protection net 602 will intercept the sand and gravel mixed in the air outside the second sand protection net 602.

[0024] A control gear disk 605 is movably connected to the outer wall of the collecting sleeve 603 through a bearing. A worm motor 606 is fixedly connected to the right side of the collecting sleeve 603 on the outer wall of the collecting sleeve 603. Tooth patterns are provided on the right side of the control gear disk 605 to cooperate with the worm motor 606. Tooth patterns are provided on the outer wall of the collecting sleeve 603, and tooth patterns are provided on the left side of the control gear disk 605 to cooperate with the collecting sleeve 603.

[0025] After the deflection vane 604 is continuously driven for a period of time, the worm motor 606 pushes the tooth pattern provided on the right side of the worm motor 606 through the provided worm, so that the worm motor 606 rotates relative to the control gear disk 605. Then, the deflection vane 604 is rotated through the worm motor 606 to change the deflection angle of the deflection vane 604. As a result, the direction of the airflow pushed by the deflection vane 604 will be changed, causing the airflow to flow from the first sand dispersion protection net 601 to the second sand protection net 602. At the second sand protection net 602, the airflow will blow from the inside of the second sand protection net 602 to the outside, thereby blowing the sand and dust attached to the outside of the second sand protection net 602 off the surface of the second sand protection net 602. At this time, sand and gravel will adhere to the outside of the first sand dispersion protection net 601. After a period of time, the worm motor 606 is used to drive the control gear disk 605 to change the deflection angle of the deflection vane 604 back to its original position, and the airflow blows from the inside of the first sand dispersion protection net 601 to the outside, thereby blowing the sand and gravel off the surface of the first sand dispersion protection net 601.

[0026] A second sweeping brush 607 is fixedly connected to the outer wall of the collecting sleeve 603 on the right side of the second sand protection net 602. A first sweeping brush 608 is fixedly connected to the outer wall of the rotating shaft 4 on the left side of the first sand dispersion protection net 601.

[0027] The second sweeping brush 607 will be driven by the docking short shaft 609 to rotate, so as to brush the outside of the second sand prevention net 602, avoiding the blockage of the second sand prevention net 602 directly caused by excessive dust. The first sweeping brush 608 will be driven by the rotating shaft 4 to rotate, so as to brush the outside of the first sand prevention net 601, avoiding the blockage of the first sand prevention net 601 directly caused by excessive dust.

[0028] Embodiment 2: Please refer to Figures 1-10 , on the basis of Embodiment 1, the present invention provides a technical solution: The light shock mechanism 7 includes a fixed frame 701, the fixed frame 701 is arranged at the bottom of the stator housing 1, an activity plate 704 is movably connected inside the fixed frame 701, the top of the activity plate 704 is fixedly connected with the bottom of the stator housing 1, a protrusion is arranged at the top of the fixed frame 701 to limit the up and down movement of the activity plate 704 within an allowable range, and a support spring 705 is fixedly connected to the bottom of the activity plate 704 inside the fixed frame 701.

[0029] Fix the fixed frame 701 to the external fixed structure, and then fix the motor, so that the motor works and is connected to the external transmission structure through the pulley 5 for work.

[0030] A first eccentric block 702 is fixedly connected to the outer wall of the docking short shaft 609 on the outside of the stator housing 1, and a second eccentric block 703 is fixedly connected to the outer wall of the rotating shaft 4 on the outside of the end cover 2.

[0031] When the motor works, the rotor 3 drives the rotating shaft 4 to rotate, and makes the docking short shaft 609 rotate together, thereby driving the first eccentric block 702 and the second eccentric block 703 to rotate around the same axis. Under the action of the second eccentric block 703 and the first eccentric block 702, the motor will drive the activity plate 704 to move up and down, making the motor generate slight up and down vibrations, and then the stator housing 1 will move up and down accordingly, so as to shake off the dust attached to its surface, prevent excessive dust from adhering to the surface of the stator housing 1, and further prevent the motor from overheating and being damaged during operation.

[0032] At the same time, when the motor vibrates up and down, the first sand prevention net 601 and the second sand prevention net 602 will also vibrate together through the stator housing 1 and the end cover 2, and then the sand stuck in the small holes of the second sand prevention net 602 and the first sand prevention net 601 will be shaken out, which is convenient for the second sweeping brush 607 and the first sweeping brush 608 to sweep it away, and thus can enhance the air circulation and the heat dissipation effect.

[0033] An elastic sand prevention net 706 is fixedly connected inside the fixed frame 701, and an air inlet plate 707 is arranged on the front surface of the elastic sand prevention net 706 on the inner wall of the fixed frame 701.

[0034] When the movable plate 704 is driven by the motor to move upward, the space at the bottom of the movable plate 704 will become larger, and then the air pressure will decrease, causing the external air to push open the intake plate 707 and enter the inside of the fixed frame 701 through the elastic sand-proof net 706. At the same time, the elastic sand-proof net 706 will block the dust outside.

[0035] An activity piece 709 is movably connected to the inside of the movable plate 704 at the bottom of the end cover 2. The activity piece 709 is provided with a limit protrusion. A top spring 708 is fixedly connected to the back of the intake plate 707 on the front of the elastic sand-proof net 706, and the elastic sand-proof net 706 has elasticity.

[0036] When the movable plate 704 moves downward, the air at the bottom of the movable plate 704 is compressed, and the air pressure at the bottom of the movable plate 704 increases, which will press the intake plate 707 outward. Then, the top spring 708 on the back of the intake plate 707 will hit the elastic sand-proof net 706, pushing away the dust on the surface of the elastic sand-proof net 706. At the same time, the gas cannot be discharged through the elastic sand-proof net 706, and the gas will push open the activity piece 709 upward. The bottom of the activity piece 709 is provided with a limit protrusion, and the upward movement range of the activity piece 709 will be restricted. This makes the gas blow from the bottom of the moved activity piece 709 to the periphery of the top surface of the movable plate 704, thereby preventing dust from accumulating near the motor and causing heat accumulation during the operation of the motor.

[0037] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
