Description

Technical Field

[0001] The invention relates to the technical field of special motors for hot air circulation fans, and in particular to a special motor for hot air circulation fans. Background Art

[0002] A hot air circulation fan is a device used for air circulation and heating, and is widely used in industrial, commercial and domestic fields. It can improve the circulation efficiency of air in the heating system and provide uniform heat distribution. Working principle: The fan draws in the surrounding cold air through the fan. The cold air is heated to the set temperature by a heater (such as an electric heater, water heater or hot air furnace). The heated air is sent out through the fan's air duct system and enters the target area. The fan continuously circulates the air to ensure a uniform temperature in the room and improve thermal efficiency.

[0003] Hot air circulation fans are important equipment for improving the efficiency of heating systems and air circulation. They have a wide range of applications and significant advantages. When selecting and using hot air circulation fans, it is necessary to make comprehensive considerations based on actual needs to ensure their performance and use effects. Regular maintenance can extend the service life of the fan and keep it in good working condition.

[0004] The motor for hot air circulation fan is a key component that drives the hot air circulation fan. Its performance directly affects the efficiency, stability and service life of the fan. The connection between the motor drive shaft and the fan blades may cause dust and impurities in the external environment to enter the connection, forming abrasives, causing wear, leading to unstable operation and increased noise. The existing motor for hot air circulation fan lacks automatic lubrication function, which will lead to increased wear, reduced efficiency, and increased risk of failure. These problems not only affect the normal operation of the equipment, but may also increase maintenance costs and affect product quality.

[0005] In summary, the prior art lacks a technology for automatically lubricating the drive shaft of a motor dedicated to a hot air circulation fan. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a special motor for a hot air circulation fan.

[0007] In order to achieve the above objectives, the technical solution adopted by the present invention is: a special motor for a hot air circulation fan, comprising a hot air circulation fan body, a device seat is fixedly installed on the hot air circulation fan body, a sliding seat is slidably provided on the device seat, a motor seat is rotatably connected to the sliding seat, a fan blade driving motor is fixedly installed on the motor seat, a rotating frame is rotatably connected to one end of the device seat, two electric push rods A are fixedly connected to the rotating frame, one of the electric push rods A is fixedly connected to a scraping mechanism, and the other electric push rod A is fixedly connected to a lubricating oil application seat.

[0008] Preferably, two slide grooves are provided on the equipment seat, a hydraulic cylinder is fixedly installed on the equipment seat, the output end of the hydraulic cylinder is connected and fixedly arranged with the sliding seat, an adjustment rack is connected and fixedly arranged on the equipment seat, and a waste oil seat is movably inserted on the equipment seat.

[0011] Preferably, a motor is fixedly connected to one end of the rotating frame, the motor is fixedly connected to the equipment seat, and a transmission rack is fixedly connected to one side of the rotating frame.

[0012] Preferably, the scraping mechanism includes a movable frame, which is connected and fixedly arranged with an electric push rod A, and an electric push rod B is connected and fixedly arranged on the movable frame, and an output end of the electric push rod B is connected and fixedly arranged with a hinge seat, and two connecting rods are rotatably connected on the hinge seat.

[0013] Preferably, a material receiving hopper is fixedly connected to one side of the movable frame, and two adjustment blocks are symmetrically structured and slidingly matched inside the movable frame. One end of the adjustment block is rotatably connected to the other end of the connecting rod, and an oil scraper is fixedly connected to the adjustment block, and the oil scraper is in sliding contact with the outer wall of the transmission shaft of the fan blade drive motor.

[0014] Preferably, an oil scraping port larger than the size of the transmission shaft of the fan blade drive motor is provided on one side of the lubricating oil application seat, a drive shaft is rotatably connected to one side of the lubricating oil application seat, a cover plate is fixedly connected to one end of the drive shaft, a guide groove is provided on the drive shaft, a fixed guide column is slidably provided in the guide groove, and one end of the fixed guide column is fixedly connected to the rotating frame.

[0018] When the drive shaft of the fan drive motor needs to be lubricated regularly, two scraper plates are used to cover the drive shaft of the fan drive motor. When the scraper plates move, the old lubricating oil on the drive shaft of the fan drive motor can be cleaned, which helps to remove the accumulated dirt, metal particles and contaminants in the lubricating oil, ensuring that the new oil can play the best lubricating effect and preventing the contaminants from further damaging the bearings;

[0019] By setting a sliding seat and a rotatable motor seat, the fan blade drive motor can be automatically driven to move away and turn, which facilitates the cleaning of old lubricating oil and the application of new lubricating oil on the transmission shaft, improves the maintenance efficiency of the equipment, extends the service life of the equipment, and reduces the safety risks during maintenance.
