Description

Technical Field

[0001] The utility model relates to the technical field of a vibrating feeder discharging structure, in particular to a mechanism for controlling the opening and closing of a vibrating feeder discharging port. Background Art

[0002] In the production process, the vibrating feeder can feed the block and granular materials from the storage bin to the receiving device evenly, regularly and continuously. In the sand and gravel production line, it can feed the crushing machinery continuously and evenly. It is widely used in the crushing and screening combined equipment in the metallurgy, coal mining, mineral processing, building materials, chemical industry, abrasive and other industries.

[0003] Traditional vibratory feeders are mostly used in continuous feeding scenarios, in which the discharge port generally does not need to be controlled. Due to special needs of the production line, some feeders are used in non-continuous feeding scenarios. In this case, the discharge port of the feeder needs to be controlled. When the feeder needs to discharge, the material blocking device is automatically opened, and when the feeder does not need to discharge, the material blocking device is automatically closed, thereby realizing flexible application and control of the vibratory feeder in special occasions.
