Often trouble, the especially downcomer with water back bending, are difficult to clean up, and downcomer long-term use cannot clear up, and dirt and urine alkali are all
Collection is pressed in crook of turning one's coat, and easily causes sewer from blocking.
Dredging machine is the instrument for clearing up dredge blockage pipeline, and it drives flexible axle to rotate to pipeline by the drum of rotation
Dredged, under non-working condition, flexible axle can be taken in the drum of dredging machine, can be pulled out when in use from drum.
The U of Publication No. CN 203008068 patent document discloses hand-held tube cleaning, and disclose automatically to
Enter drive device, the automatic feed drive device includes the intersection wheel of three radially even distributions.During work, filled by compressing
Put compression and intersect wheel, make three it is equally distributed intersect wheel while compress flexible axle, by wind or electric hand drill rotating cylinder with
Drive shaft driving flexible axle rotates, and the helical angle for promoting flexible axle to take turns to be formed along three equally distributed intersections is advanced automatically or retrogressing,
Intersection wheel flexible axle is unclamped then to halt or retreat.But the automatic feed drive device only has one group of control flexible axle to advance with after
Flexible axle can only advance and can not retreat during the oblique bearing, i.e. instrument main story moved back, and flexible axle can only be retreated and can not advanced when instrument inverts,
This defect can result in blockage thing without hair take out possibility, i.e.,：Pipeline is sent into when flexible axle rotates forward, tamper (such as hair) is hooked in front end
Prepare to take out pipeline, but the function of now retreating without control flexible axle, to retreat, then need to be inverted, cut by switch controlled motor
The reverse rotation of roller is changed, now flexible axle is also derotation, and because flexible axle is dextrorotation spring, the tamper hooked after derotation is from flexible axle
End, which screws out, to be come off, and tamper can not also be taken out by being retreated even if flexible axle, and tool performance substantially reduces.
