Grille guide wheel

The nylon rake teeth guide wheel in the mechanical grille accessories includes the frame, drive transmission system, transmission guide wheel, support wheel, and closed rotary traction chain that rotates around it, as well as the rake teeth and grid bars. Under the drive of the motor reducer, the rotating traction chain rotates from bottom to top. When the rake shaft on the traction chain rotates to the upstream surface of the grating, the rake teeth are inserted into the gap of the grating and perform a cleaning action from bottom to top, scraping off the debris trapped on the grating into the rake.
