A dustproof feeding device

Abstract

This utility model relates to the technical field of feeding devices, and in particular to a feeding device with dustproof function. It includes a pipe installed on a conveyor belt, an air outlet pipe fixedly installed on the pipe, a cleaning frame slidably installed inside the air outlet pipe, a drive structure connected to the cleaning frame on one side of the air outlet pipe, a filter assembly installed inside the air outlet pipe, and a collection pipe cooperating with the filter assembly on one side of the air outlet pipe. A guide port is provided between the air outlet pipe and the collection pipe. The drive structure drives the cleaning frame to move up and down periodically to clean the inner wall of the air outlet pipe, scraping off the attached dust and preventing the inner diameter of the air outlet pipe from gradually decreasing due to long-term dust accumulation, thus maintaining the working efficiency of the dustproof device. The filter screen filters large dust particles in the airflow, preventing large dust particles from impacting the spray assembly and accelerating wear.
