Description
Technical Field
[0001] This utility model relates to the field of sweeper motor technology, and in particular to a heat dissipation structure for a sweeper motor. Background Technology
[0002] The motor of the sintering plant cleaner is a key power component that ensures the stable operation of sintering production. In the sintering plant, belt conveyors are widely used for raw material transfer in various processes. The cleaner motor often drives components such as roller brushes. Its working principle is that the motor drives the roller brush, and the brush tip contacts the conveyor belt. The roller brush rotates in the opposite direction to the direction of the conveyor belt, thereby removing adhering materials. The motor power is usually between 1 and 3 kW, which can be adapted to different specifications of cleaning equipment. The voltage is mostly 380V industrial power, and it can work stably in environments from -20℃ to 60℃. It has a compact structure and works in conjunction with the reducer, roller brush, etc. to effectively clean the surface of the conveyor belt, reduce material residue, reduce equipment wear, improve production efficiency, and help sintering production to be efficient and environmentally friendly.
[0003] However, most existing systems use worm gear reducers, which can easily lead to frequent motor overload, resulting in serious damage such as motor burnout. At the same time, because the cleaner is interlocked with the belt scale, motor and reducer failures can directly cause material feeding fluctuations, interfere with the stability of material composition, and have an adverse impact on the production process. Utility Model Content
[0004] The purpose of this utility model is to solve the problems in the existing technology where the use of worm gear reducers easily leads to frequent motor overload, resulting in serious damage such as motor burnout. At the same time, because the cleaner is interlocked with the belt scale, the failure of the motor and reducer will directly cause material feeding fluctuations, interfere with the stability of material composition, and have an adverse impact on the production process. Therefore, a heat dissipation structure for the cleaner motor is proposed.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a heat dissipation structure for a sweeper motor, comprising a motor body, a reducer, and a heat dissipation device. The reducer is located at the drive end of the motor body, and the heat dissipation device is disposed on the surface of the motor body. The heat dissipation device includes a connecting plate, which is fixedly connected to the motor body. A frame is fixedly connected to one end of the connecting plate, and an air guide sleeve is fixedly connected to the end of the frame away from the connecting plate. A drive motor is fixedly connected to the end of the motor body near the air guide sleeve, and a fan blade is fixedly connected to the drive end of the drive motor. The air guide sleeve is fitted onto the fan blade, and the opening of the air guide sleeve faces the fins on the surface of the motor body. By setting up the heat dissipation device and replacing the cycloidal pin reducer, the transmission efficiency can be improved, and the motor overload can be reduced. The drive motor drives the fan blade to rotate, and the airflow is guided to the fins through the air guide sleeve to accelerate heat exchange. At the same time, the bending rod drives the brush to clean the dust on the fins, and the spring cooperates with the push rod to make the brush fit the concave and convex surfaces of the fins, which greatly improves the heat dissipation efficiency and reduces the probability of the motor burning out due to overheating and overload.
[0006] Preferably, the drive end of the drive motor is fixedly connected to a bent rod, which is arranged in an "L" shape. By setting the bent rod, when the drive motor drives the fan blades to rotate, the bent rod rotates synchronously with the drive motor and drives the brush to move through its own rotation, so that the brush can clean the surface of the fins, thereby reducing the accumulation of dust on the fins and reducing the impact of dust on the heat dissipation effect of the fins. At the same time, in conjunction with the spring and push rod, it ensures that the brush can adapt to the concave and convex surfaces of the fins and ensures the cleaning effect.
[0007] Preferably, a rectangular strip is fixedly connected to one end of the bent rod. The surface of the rectangular strip has through holes, and a push rod is slidably connected to the inner wall of the through holes on the surface of the rectangular strip. By setting the push rod and cooperating with the spring, the brush can move freely on the uneven fins, thereby better cleaning the dust on the surface of the fins. Under the elastic action of the spring, it can extend or swing according to the shape change of the fin surface, ensuring that the brush always maintains good contact with the fin surface to effectively remove dust and maintain the heat dissipation efficiency of the fins.
[0008] Preferably, a brush is fixedly connected to the lower surface of the push rod. The brush contacts the fins on the surface of the motor body. By setting the brush, it moves under the action of the bending rod to clean the surface of the fins, remove the attached dust, and reduce the impact of dust accumulation on the heat dissipation efficiency of the fins. At the same time, in conjunction with the spring and the push rod, the brush can move freely on the uneven fins to ensure thorough cleaning, reduce dust residue that hinders heat exchange, maintain the efficient operation of the heat dissipation device, and most of the dust swept away can be blown away by the airflow brought out by the fan blades, reducing the burden on subsequent dust prevention components.
[0009] Preferably, there are two push rods arranged symmetrically, and a spring is fixedly connected to the upper surface of the brush, with the end of the spring away from the brush being fixedly connected to a rectangular strip.
[0010] Preferably, a dustproof component is provided on the lower surface of the motor body. The dustproof component includes a magnetic suction plate, which is fixedly connected to the lower surface of the air guide sleeve. An iron plate is provided on the lower surface of the magnetic suction plate, and a round hole is opened on the surface of the iron plate. A rod is fixedly connected to the lower surface of the magnetic suction plate, and the rod is inserted into the round hole on the surface of the iron plate. The iron plate and the magnetic suction plate are magnetically connected. By setting the dustproof component, the filter screen can adhere to the dust that is raised, reducing its re-attachment to the motor. Furthermore, pulling the iron plate and the magnetic suction plate can easily remove the filter screen for cleaning, reducing the continuous impact of dust on the motor and heat dissipation components, ensuring stable operation of the equipment, and reducing the fluctuation of material feeding and the impact of composition caused by failure.
[0011] Preferably, a filter screen is fixedly connected to one end of the iron plate. The filter screen is located directly below the motor body. By setting the filter screen, after the brush sweeps the dust off the surface of the fins, a small portion of the dust that falls to the ground below the motor after the airflow stops and may re-adhere to the motor after dust is stirred up is intercepted. By trapping the dust that is thrown up, the filter screen is reduced from re-adhering to the motor and fins and affecting heat dissipation. At the same time, the filter screen can be removed by pulling the iron plate and separating it from the magnetic plate, which is convenient for cleaning or replacement, so as to maintain the dustproof effect continuously.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by incorporating a heat dissipation device, the original worm gear reducer is replaced with a cycloidal pin reducer during operation. When the cycloidal pin reducer is working, the drive motor rotates the fan blades, which in turn drive airflow. The air guide sleeve directs the airflow to the fins, accelerating the heat exchange rate. Simultaneously, as the drive motor rotates the fan blades, the bending rod follows the drive motor's rotation, moving the brush. The brush cleans dust from the fin surface, reducing the impact of dust on heat dissipation. A spring, in conjunction with a push rod, allows the brush to move freely across the uneven fins. By incorporating the heat dissipation device and replacing the cycloidal pin reducer, transmission efficiency is improved, motor overload is reduced, and the drive motor rotates the fan blades, guiding airflow through the air guide sleeve to the fins for accelerated heat exchange. Simultaneously, the bending rod drives the brush to clean dust from the fins, and the spring, in conjunction with the push rod, allows the brush to adapt to the uneven surface of the fins, significantly improving heat dissipation efficiency and reducing the probability of motor burnout due to overheating and overload.
[0013] In this invention, by setting up a dustproof component, when the brush sweeps the dust off the surface of the fins, most of the dust is blown away by the airflow carried by the fan blades. A small portion will fall back to the ground below the motor after the airflow stops, and is prone to re-adhere to the motor after dust is stirred up. The filter screen is located below the motor, and when dust rises, it is stuck to the filter screen. Pulling the iron plate and the magnetic plate separates the filter screen, which can then be removed. By setting up the dustproof component, the filter screen can trap the stirred-up dust, reducing its re-adhesion to the motor. Furthermore, pulling the iron plate and the magnetic plate separates the filter screen for easy removal and cleaning, reducing the continuous impact of dust on the motor and heat dissipation components, ensuring stable operation of the equipment, and reducing material feeding fluctuations and compositional effects caused by malfunctions.

[0016] Please see Figures 1-5 This utility model provides a technical solution: a heat dissipation structure for a sweeper motor, including a motor body 1, a reducer 2 and a heat dissipation device 3. The reducer 2 is located at the drive end of the motor body 1, and the heat dissipation device 3 is located on the surface of the motor body 1.
[0017] In this implementation scheme: the heat dissipation device 3 includes a connecting plate 32, which is fixedly connected to the motor body 1. A frame 33 is fixedly connected to one end of the connecting plate 32, and an air guide sleeve 31 is fixedly connected to the end of the frame 33 away from the connecting plate 32. A drive motor 34 is fixedly connected to the end of the motor body 1 near the air guide sleeve 31. A fan blade 36 is fixedly connected to the drive end of the drive motor 34. The air guide sleeve 31 is fitted with the fan blade 36, and the opening of the air guide sleeve 31 faces the fins on the surface of the motor body 1. By setting up the heat dissipation device 3 and replacing the cycloidal pin reducer 2, the transmission efficiency can be improved and the motor overload can be reduced. The drive motor 34 drives the fan blade 36 to rotate, and the airflow is guided to the fins through the air guide sleeve 31 to accelerate heat exchange. At the same time, the bending rod 37 drives the brush 311 to clean the dust on the fins. The spring 310 cooperates with the push rod 39 to make the brush 311 fit the concave and convex surfaces of the fins, which greatly improves the heat dissipation efficiency and reduces the probability of the motor burning out due to overheating and overload.
[0018] Specifically, a bent rod 37 is fixedly connected to the drive end of the drive motor 34. The bent rod 37 is L-shaped. By setting the bent rod 37, when the drive motor 34 drives the fan blade 36 to rotate, the bent rod 37 rotates synchronously with the drive motor 34. The bending rod 37 drives the brush 311 to move through its own rotation, so that the brush 311 can clean the surface of the fins, thereby reducing the accumulation of dust on the fins and reducing the impact of dust on the heat dissipation of the fins. At the same time, in conjunction with the spring 310 and the push rod 39, it ensures that the brush 311 can adapt to the uneven surface of the fins and ensure the cleaning effect.
[0019] Specifically, a rectangular bar 38 is fixedly connected to one end of the bent rod 37. The surface of the rectangular bar 38 has through holes, and a push rod 39 is slidably connected to the inner wall of the through holes on the surface of the rectangular bar 38. By setting the push rod 39, in conjunction with the spring 310, the brush 311 can move freely on the uneven fins, thereby better cleaning the dust on the surface of the fins. Under the elastic action of the spring 310, it can extend, retract, or swing according to the shape change of the fin surface, ensuring that the brush 311 always maintains good contact with the fin surface, so as to effectively remove dust and maintain the heat dissipation efficiency of the fins.
[0020] Specifically, a brush 311 is fixedly connected to the lower surface of the push rod 39. The brush 311 contacts the fins on the surface of the motor body 1. By setting the brush 311, it moves under the drive of the bending rod 37 to clean the surface of the fins, remove the attached dust, and reduce the impact of dust accumulation on the heat dissipation efficiency of the fins. At the same time, in conjunction with the spring 310 and the push rod 39, the brush 311 can move freely on the concave and convex fins to ensure thorough cleaning, reduce dust residue that hinders heat exchange, maintain the efficient operation of the heat dissipation device 3, and most of the dust swept away can be blown away by the airflow brought out by the fan blade 36, reducing the burden on the subsequent dustproof component 35.
[0021] Specifically, there are two push rods 39, which are arranged symmetrically. A spring 310 is fixedly connected to the upper surface of the brush 311, and the end of the spring 310 away from the brush 311 is fixedly connected to the rectangular strip 38.
[0022] Specifically, a dustproof component 35 is provided on the lower surface of the motor body 1. The dustproof component 35 includes a magnetic suction plate 351, which is fixedly connected to the lower surface of the air guide sleeve 31. An iron plate 352 is provided on the lower surface of the magnetic suction plate 351. A round hole is opened on the surface of the iron plate 352. A plug rod 353 is fixedly connected to the lower surface of the magnetic suction plate 351. The plug rod 353 is inserted into the round hole on the surface of the iron plate 352, and the iron plate 352 is magnetically connected to the magnetic suction plate 351.
[0023] In this embodiment: by setting up the dustproof component 35, the filter screen 354 can stick to the dust that is raised, reducing its re-attachment to the motor, and the filter screen 354 can be easily removed for cleaning by pulling the iron plate 352 and the magnetic suction plate 351 apart, reducing the continuous impact of dust on the motor and heat dissipation components, ensuring stable operation of the equipment, and reducing the fluctuation of material feeding and the impact of composition caused by failure.
[0024] Specifically, a filter screen 354 is fixedly connected to one end of the iron plate 352, and the filter screen 354 is located directly below the motor body 1.
[0025] In this embodiment: by setting up a filter screen 354, after the brush 311 sweeps the dust off the surface of the fins, a small portion of the dust that falls to the ground below the motor after the airflow stops and may re-adhere to the motor after dust is stirred up is intercepted. By trapping the dust that is stirred up, the filter screen 354 reduces the amount of dust that may re-adhere to the motor and fins and affect heat dissipation. At the same time, the filter screen 354 can be removed by pulling the iron plate 352 and the magnetic plate 351 to facilitate cleaning or replacement, so as to maintain the dustproof effect continuously.
[0026] Working principle: By setting up a heat dissipation device 3, the original worm gear reducer 2 is replaced with a cycloidal pin reducer 2 during use. When the cycloidal pin reducer 2 is working, the drive motor 34 drives the fan blade 36 to rotate. The rotation of the fan blade 36 drives the airflow, and the air guide sleeve 31 guides the airflow to the fins, accelerating the heat exchange speed of the fins. At the same time, when the drive motor 34 drives the fan blade 36 to rotate, the bent rod 37 follows the drive motor 34 to rotate. The bent rod 37 drives the brush 311 to move. When the brush 311 moves, it sweeps the dust on the surface of the fins, reducing heat exchange. With less dust affecting heat dissipation, the spring 310, in conjunction with the push rod 39, facilitates the free movement of the brush 311 on the concave and convex fins. By setting up the heat dissipation device 3 and replacing the cycloidal pin reducer 2, the transmission efficiency can be improved, and the motor overload can be reduced. The drive motor 34 drives the fan blade 36 to rotate, and guides the airflow to the fins through the air guide sleeve 31 to accelerate heat exchange. At the same time, the bending rod 37 drives the brush 311 to clean the dust on the fins. The spring 310, in conjunction with the push rod 39, makes the brush 311 fit the concave and convex surfaces of the fins, which greatly improves the heat dissipation efficiency and reduces the probability of the motor burning out due to overheating and overload. By setting up the dustproof component 35, when the brush 311 sweeps the dust off the fin surface, most of the dust is blown away by the airflow brought out by the fan blade 36. A small portion will fall back to the ground below the motor after the airflow stops, and it is easy for the dust to re-adhere to the motor after being stirred up. The filter screen 354 is located below the motor. When the dust rises, it is stuck to the filter screen 354. Pulling the iron plate 352 and the magnetic plate 351 separates the filter screen 354, which can then be removed. By setting up the dustproof component 35, the filter screen 354 can stick to the stirred-up dust, reducing its re-adhesion to the motor. Furthermore, pulling the iron plate 352 and the magnetic plate 351 separates the filter screen 354 for easy removal and cleaning, reducing the continuous impact of dust on the motor and heat dissipation components, ensuring stable operation of the equipment, and reducing the fluctuations in material feeding and composition caused by malfunctions.
