DEVICE FOR PREVENTING NOZZLE BLOCKING

摘要

A device for preventing clogging of spray nozzles is provided to be able to prevent clogging of the spray nozzles by a structure in which a separate power is not required by allowing a solution supplied to the spray nozzles to drive the structure. As a device installed on a solution supply pipe(10) to prevent alien substances from clogging spray nozzles for spraying a solution, the device for preventing clogging of the spray nozzles comprises: a rotary power providing part(40) including a rotary shaft(30) mounted on an inner part of the solution supply pipe such that the rotary shaft is rotatable along the length direction of the pipe, and a propeller(42) installed on the rotary shaft and rotated by a flow of the solution; an alien substance crushing part(50) including a crushing rod(52) movably mounted along the center line of the spray nozzles; and a roller(57) which is rotatably mounted on the crushing rod and a cam(38) mounted on the rotary shaft and comes in contact with the cam to convert a rotational motion of the propeller into a straight reciprocating motion of the crushing rod.
