PURPOSE: An apparatus for detecting close of dust transfer path in dust collector is provided to accurately sense blocking of the transfer path of collected dust by pressure variation. CONSTITUTION: The apparatus comprises first pressure inlet pipe an one end of which is connected to duct(12) so that the first pressure inlet pipe approaches the front side of foreign material removal plate for filtering foreign materials, and the other end of which is formed in a shape of vertical pipe(22), the vertical pipe(22) has long length in a gravitational direction; second pressure inlet pipe one end of which is connected to the duct(12) so that the second pressure inlet pipe gets away toward the front of the foreign material removal plate, and the other end of which is formed in a shape of vertical pipe(32), the vertical pipe(32) has long length in a gravitational direction; first detection rod(26) and second detection rod(36) vertically movably mounted on the guiding plates(41,42) by respectively penetrating guiding plates(41,42) positioned in the lower part of the vertical pipes(22,32); cutoff plates(24,34) mounted on the upper part of the first detection rod(26) and second detection rod(36) to open and close the lower part of the vertical pipes(22,32); a proximity sensor(28) for transmitting signals by sensing descent of the first detection rod(26); a weight(38) installed at the lower part of the second detection rod(36); and a control rod(52) both end parts of which are positioned on descent path of the cutoff plates(24,34), and the central part of which is rotationally mounted on rotation supporting shaft(50).
