Description

Technical Field

[0001] The utility model relates to the technical field of scraper motor bases, in particular to a scraper motor base with good stability. Background Art

[0002] The common conveying equipment - scraper, is widely used in metallurgy, coal, mining, grain and oil, food, feed and other fields. The scraper is a continuous transportation equipment that conveys bulk materials in a closed rectangular cross-section shell with the help of a moving scraper chain; because a stepper motor is needed to drive the scraper chain to work when conveying materials, a base is needed to fix the stepper motor.

[0003] However, when the existing scraper motor base is put into use, the motor is fixed with screws and nuts. However, as the motor vibrates during operation, the screws and nuts are easily loosened during the vibration. When the screws and nuts are loose, the motor will shake, causing the output shaft to collide with the machine during operation, thereby causing the motor to be damaged. At the same time, during the transportation of feed, the vibration causes the feed to splash, causing the feed to enter the motor through the gap. When the motor continues to work, it is easy to cause the motor to be damaged, requiring manual repair, thereby increasing labor costs. Utility Model Content

The central axis of the bidirectional threaded rod 10 is symmetrically designed, and a connecting block 12 is bolted to one side of the sleeve 11. Under the cooperation of the turntable 9 and the bidirectional threaded rod 10, the sleeve 11 can drive the connecting blocks 12 on both sides to move in the direction of the output shaft of the stepper motor 2 at the same time. A fixed block 13 is bolted to one side of the connecting block 12, and an arc plate 14 is bolted to one side of the connecting block 12. The cross-sectional shape of the arc plate 14 is a semicircular design, so that the output shaft of the stepper motor 2 can be more comprehensively protected. Under the action of the movement of the connecting block 12, the connecting block 12 can drive the fixed block 13 and the arc plate 14 to move. The fixing block 13 and the arc plate 14 are moved so as to protect the stepper motor 2, which effectively prevents the feed from falling into the stepper motor 2 during transportation and causing damage to the stepper motor 2, thereby increasing the safety of the stepper motor 2 and extending the service life of the stepper motor 2, thereby improving the practicality of the base.

The surface of the slider 153 is slidably connected to the inner cavity of the fixed shell 151, which effectively prevents the slider 153 from rotating during operation, thereby increasing the stability of the guide mechanism 15.

[0025] Working principle: First, the staff bolts the stepper motor 2 to the top of the bottom shell 1 through the bolt assembly 3. When the bolt assembly 3 needs to be limited, the staff uses the moving rod 51 to make the moving block 52 drive the compression spring 53 to be compressed, and the moving block 52 can move to the inside of the installation shell 6. Then the staff moves the installation shell 6 to the inner cavity of the bottom shell 1. Under the action of the rebound of the compression spring 53, the moving block 52 moves to the inner cavity of the bottom shell 1, thereby limiting the blocking plate 4, so that the blocking plate 4 can block the bolt assembly 3. When it is necessary to prevent feed from entering the stepper motor 2, the staff uses the turntable 9 to make the bidirectional threaded rod 10 drive the sleeves 11 on both sides to move simultaneously in the direction of the output shaft of the stepper motor 2, and the sleeve 11 drives the fixed block 13 and the arc plate 14 to move simultaneously through the connecting block 12, so that the arc plate 14 and the fixed block 13 can block one side of the stepper motor 2 to prevent feed from entering the stepper motor 2. After the stepper motor 2 is installed, the staff turns on the stepper motor 2 to make the scraper work.
