AIR INLET OPENING AND CLOSING APPARATUS FOR AIRCONDITIONER CEREALS SELECTION FOR ELECTRIC FAN

摘要

The present invention provides a more even opening and closing of the air intake port which determines the wind speed of the tuyere when sorting different kinds of grains with different weights of grains, and precisely adjusting the selection of the opening and closing range. Provide an air inlet opening and closing device.;In order to achieve the above object, the present invention has a plurality of air inlets 11a circumferentially on the sidewall of the tuyeres B provided with the blower fan C, and guide holes 12a on the outer circumferential surface of the air inlet. Hole and the rotary plate 1 having the same communication hole 11 as the air inlet 11a of the tuyere B is located on the inner side to form the connection hole 12 at the same position as the guide hole 12a. In addition, the air inlet opening and closing device of the grain opening for grain sorting to be opened and closed by combining the movable bolt (2) and the tightening nut (3) in the inner surface of the connecting hole (12) and the guide hole (12a).;Air vents, air intakes, guide holes, swivel plates, communication holes, connectors, movable bolts, tightening nuts.
