Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor device used for grain crushing. Background Art

[0002] The grain mill is a machine that grinds various grains, Chinese medicinal materials and other foods into uniform powder. The grain mill grinds the materials into powder by two grinding discs covered with teeth. It operates in a continuous feeding mode, with precise structure, low noise, easy operation, fine grinding and no dust. It is suitable for supermarkets, shopping mall counters and grain processing stores. The grain mill changes the shortcomings of the iron mill, such as rough surface, high noise, coarse powder, difficult to clean, and insufficient motor power. The processed food meets the food hygiene requirements.

[0003] The grain grinding machine mainly consists of a feed hopper, rotor, toothed disc, sieve, casing, base, motor and other parts. When the material enters the grinding chamber, it is quickly broken into fine powder or slurry under the continuous impact of the round teeth and flat teeth and the rubbing of the toothed disc. Under the action of centrifugal force and airflow, it passes through the sieve holes and is discharged to the outside of the room through the discharge port. The grain grinder uses a motor as the power. In order to prevent the floating particles generated during grain grinding from falling into the motor, a motor with better sealing is often used.

[0004] However, there are still the following disadvantages: the motor used for grain crushing has a large resistance during operation, and a large power motor is required. The motor generates a lot of heat during operation, but the motor with a good sealing type is not conducive to the ventilation and heat dissipation of the motor. Therefore, we propose a motor device for grain crushing to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a motor device used for grain crushing to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a motor device used for grain crushing, comprising an output shaft, the outer surface of the output shaft is provided with a top shell through a first bearing rotation sleeve, the right end of the output shaft is provided with a mounting shell, the mounting shell is provided with a rotor and a stator, the mounting shell is provided with a cooling device, and the cooling device includes a cooling part;

[0008] A filter portion is provided inside the installation shell;

[0009] The filter unit includes a filter screen, a roller and a bracket. The outer surface of the bracket is fixedly connected to the outer surface of the output shaft. A groove is provided on the front of the bracket. The outer surface of the roller is rotatably connected to the inner wall of the groove through a bearing seat.

[0010] A further improvement is that the cooling part also includes a first fan, a protective shell, a first gear and a third fan, the first gear is fixedly sleeved on the outer surface of the output shaft, the outer surface of the first gear is meshingly connected with the outer surface of the second gear, and by arranging the first gear, the second gear, the rotating shaft and the second fan, when the output shaft rotates, the first gear and the second gear are utilized to make the output shaft drive the rotating shaft and the second fan to rotate, so that the wind body moves to the left, thereby cooling the inside of the device.

By setting up the protective shell, the protective shell is used to protect the stator and the rotor, thereby reducing the wind passing through the gap between the stator and the rotor and reducing the evaporation of the lubricating liquid.

[0012] A further improvement is that the third fan is fixedly sleeved on the outer surface of the output shaft, and the rotation direction of the third fan blades is opposite to that of the second fan blades. By setting the third fan, the second fan and the third fan have opposite rotation directions, but the blades have opposite rotation directions, thereby accelerating the flow rate of the wind inside the motor.

[0013] A further improvement is that the filter part also includes a protrusion and a spring, the outer surface of the filter is slidably connected to the inner wall of the mounting shell, the right end of the spring is fixedly connected to the inner wall of the mounting shell, and the left end of the spring is fixedly connected to the right end surface of the filter. By arranging the spring and the filter, the filter is used to filter the wind to prevent dust and impurities from affecting the operation of the motor.

[0014] A further improvement is that the right end face of the protrusion is fixedly connected to the inner wall of the filter, and the right end face of the roller extends into the interior of the filter and contacts the inner wall of the filter. By setting a bracket, a roller and a protrusion, the output shaft drives the bracket and the roller to rotate, and the roller hits the protrusion, causing the filter to vibrate and shake off the dust on the right end face of the filter.

[0015] A further improvement is that the right end of the mounting shell is sleeved on the outer surface of the right end of the top shell, and a bolt is provided on the left side of the top shell. The outer surface of the right end of the bolt is threadedly penetrated through the left end surface of the top shell, the left end surface of the mounting shell and the left end surface of the stator in sequence and extends to the inside of the stator, so as to facilitate splicing of the device.
