[0013] The present invention has the following beneficial effects: (1) The present invention discloses an anti-blocking dust collector inlet flue dust cleaning device. Cleaning liquid is introduced into a hollow threaded rod through a water inlet pipe. The cleaning liquid in the hollow threaded rod is sprayed out from a plurality of strip-shaped water outlet grooves. Then, a driving motor is started to drive the hollow threaded rod to rotate. At this time, the cleaning liquid sprayed from the strip-shaped water outlet grooves is sprayed in a rotating manner. The hollow threaded rod drives the transmission plate to rotate. When the transmission plate rotates and contacts the L-shaped connecting plate, the L-shaped connecting plate moves toward the flue. At this time, the limit spring is stretched and deformed, and the L-shaped connecting plate is Drive several circular sleeves to move, and the circular sleeves will pass through the strip water outlet groove. When the circular sleeves pass through the strip water outlet groove, the direction of the water spraying of the strip water outlet groove will be changed by the movement of the circular sleeves, so that the direction of the water spraying will be the same as the direction of the movement of the circular sleeves, so that the cleaning liquid can cover the L-shaped circular groove at more angles, and the curved part in the L-shaped circular groove can be sprayed and cleaned in an all-round manner. After the transmission plate leaves the L-shaped connecting plate, the L-shaped connecting plate will be reset under the elastic force of the limit spring 1, so that the reciprocating can effectively improve the cleaning work of the soot and dirt in the L-shaped circular groove; (2) The present invention provides an anti-blocking dust collector inlet flue dust cleaning device. The cleaning liquid entering the hollow threaded rod will enter the hollow circular tube from the second connecting hollow circular block, then enter the hollow sliding sleeve from the leakage groove on the hollow circular tube, and then spray out from a plurality of strip drainage grooves. Since the strip drainage grooves are distributed on the hollow sliding sleeve in different sizes, the hollow sliding sleeve will rotate under the action of the pressure difference when the strip drainage grooves spray out the cleaning liquid. The hollow sliding sleeve will drive the hollow circular tube to rotate, so that the cleaning liquid can be sprayed onto the inner wall of the L-shaped circular groove. The transmission plate rotates at the same time. The special-shaped plate will contact the special-shaped plate, and the special-shaped plate will move toward the direction close to the flue. At this time, the limit spring 2 will be stretched and deformed, and the special-shaped plate will drive the trapezoidal limit plate to move synchronously. The trapezoidal limit plate will drive several hollow sliding sleeves to rise synchronously. After the transmission plate leaves the special-shaped plate, the trapezoidal limit plate will be reset under the elastic force of the limit spring 2. At this time, the hollow sliding sleeve will drop under the action of its gravity. In this way, the reciprocating hollow sliding sleeve will reciprocate up and down. At this time, the cleaning liquid sprayed from the strip drainage groove will fully flush the L-shaped circular groove to ensure the comprehensiveness of the L-shaped circular groove cleaning; (3) The present invention provides an anti-blocking dust collector inlet flue dust cleaning device. The cleaned sewage will be discharged from the flue through a plurality of sewage troughs and the grooves on the closing frame. After cleaning, the driving motor is reversed, and the driving motor drives the hollow threaded rod to reverse. The hollow threaded rod drives the T-shaped internal threaded plate, and the T-shaped internal threaded plate drives the connecting plate to move toward the flue. The connecting plate drives the movable plate to descend, and the movable plate drives the T-shaped closing plate to descend. The T-shaped closing plate drives the trapezoidal limit block to descend, and the trapezoidal limit block will contact the closing frame, and the closing frame will move toward the direction close to the closing spring. The closing spring will be compressed and deformed. At this time, the closing frame will close the plurality of sewage troughs. At this time, the groove on the T-shaped closing plate also overlaps with the L-shaped circular groove, ensuring that the L-shaped circular groove can smoothly exhaust smoke during use; (4) The present invention provides an anti-blocking dust collector inlet flue dust cleaning device. Before cleaning, the driving motor rotates forward, and the driving motor drives the hollow threaded rod to rotate. The hollow threaded rod drives the T-shaped internal threaded plate to move in the direction close to the driving motor. At this time, the T-shaped internal threaded plate will contact the adaptation ring during the movement, and the adaptation spring will be compressed and deformed. After the adaptation ring leaves the thread on the transmission plate, the adaptation spring will support the adaptation ring under the action of elastic force, and the adaptation ring will support the T-shaped internal threaded plate. At this time, the T-shaped internal threaded plate will not move anymore, and the corresponding T-shaped internal threaded plate will not affect the normal rotation of the hollow threaded rod.
