[0002] A material chute is a material conveying device used to safely and efficiently transport bulk materials from a height to a designated location. Its principle is that gravity causes the material to enter the chute through the feed port and slide down the pipe to the discharge port. Due to its simple structure and easy maintenance, the material chute is widely used in industries such as cement, coal, and chemicals.

[0003] In order to prevent materials from clogging the pipeline, traditional down chute mostly uses motor vibration or wind transportation. However, this will cause a large amount of dust to be raised in the pipeline and cannot be handled. It will be discharged from the down chute along with the material. It is not only easy to enter the interior of the machine, causing damage to the machine and reducing the service life of the machine, but also too much dust in the workshop can easily cause safety hazards, and employees who are in a dusty environment for a long time will be harmful to their health.
