Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing equipment, in particular to a vibrating feeder for ore dressing. Background Art

[0002] Vibrating feeders are widely used in mining, coal and other industries. The exciting force generated by the vibration motor makes the vibrating body vibrate continuously, thereby pushing the material to the conveying trough to achieve continuous conveying of the material.

[0003] The hopper of the existing vibrating feeder is connected and fixed to the base by a spring, and the inclination angle of the hopper is fixed relative to the base. The inclination angle is not easy to adjust quickly. There are differences in the friction between minerals of different properties and the hopper. When the inclination angle of the hopper is too large and there are many minerals in the hopper, it is easy to cause accumulation and blockage in the conveying trough. When the inclination angle of the hopper is small, the feeding speed of the vibrating feeder is slow, affecting the efficiency of mineral processing. Adjusting the inclination angle of the hopper often requires adjusting the inclination angle of the base, which is very inconvenient.

[0004] The publication number is: CN210939847U, and the name is: A vibrating feeder for producing aerated concrete blocks, specifically including a base, a controller is provided on the top of the base, and lower sleeves are fixedly connected to both sides of the top of the base, the top of the lower sleeve is movably sleeved with a sleeve rod, the top of the sleeve rod is movably sleeved with an upper sleeve, and the middle of the sleeve rod is movably sleeved with a first spring. The vibrating feeder for producing aerated concrete blocks drives the piston rod to extend and retract through the cylinder, thereby adjusting the height of one end of the vibration plate and forming a height difference with the other end of the vibration plate, thereby adjusting the angle of the vibration plate, which is convenient for controlling the falling speed of the material on the vibration plate, and then controlling the feeding amount of the vibrating feeder. At the same time, the device controls the operation of the cylinder through the controller, which improves the convenience and accuracy of adjusting the angle of the vibration plate, making it more convenient to use and having higher adjustment accuracy.

[0005] Although the above device can control the operation of the cylinder and adjust the angle of the vibration plate through a controller, the structural design is relatively complex, inconvenient to operate and maintain, resulting in a short service life of the entire device; furthermore, the stability performance of the hopper support is poor.
