DEVICE FOR DRAINAGE PIPES INNER SURFACE CLEANING Russian patent published in 2004 - IPC

FIELD: agriculture; drainage pipes cleaning.

SUBSTANCE: the invention is dealt with agriculture and may be used to increase efficiency of the drain pipes cleaning. The device contains: a detachable hollow housing with a front nozzle and back jet nozzles; a water duct rigidly fixed inside the housing; a pneumatic tool of impact action mounted in the water duct; a front gear of the pulse jets agitation located in a front part of the device; the rear gears of the pulse jets agitation mounted in a slant part of the water ductand a back slant part of the housing; air nozzles mounted in the rear slant part of the housing between the rear jet nozzles. The pneumatic tool of impact action contains: a pneumatic cylinder with an air distribution valve system; a piston; an anvil block with the process holes mounted in a guiding bush and put on an axial water-feeding pipe; an air duct fixed in the tail of the cylinder; a pusher, the tail part of which is slant and rigidly linked with the anvil block; a return spring. The front gear of the pulse jets agitation contains: an axial water-feeding pipe rigidly mounted in the body of the cylinder and passing along its axes; a front nozzle, that forms a stream and is rigidly linked with the anvil block; a guiding bush rigidly fixed in the front part of the housing; the rear gears of the pulse jets include: jet nozzles made streams-forming with the process holes, guiding connection pipes and bushes, return springs and thrust washers. The invention ensures increase of efficiency of the pipes inner surface cleaning and decrease of the working substance consumption.

EFFECT: increase of efficiency of the pipes inner surface cleaning and decrease of the working substance consumption.
