Cross threaded connection.The sum of fixed cylinder 24 and the length of exntension tubs 25 are equal to the sum of fixing axle 211 and the length of outrigger shaft 212, i.e.,
When sliding block 241 is located in fixing groove 252, the closed end of fixed cylinder 24 is stretched out in the upper end of fixing axle 211, under outrigger shaft 212
End is flushed with the lower end surface of exntension tubs 25.The fan-shaped blade 23 of lower end setting at least two of outrigger shaft 212, the knife of the present embodiment
Piece 23 is seven, and seven blades 23 are circumferentially uniformly distributed along the end face of dirt removing tube 2, and the inclination of blade 23 is fixed on outrigger shaft 212
Lower end, and the blade level height of blade 23 is lower than knife spine, in this way when blade 23 is rotated with outrigger shaft 212, compared with the knife of downside
Sword can cut tamper, and the tamper for being cut into sheet is included in dirt removing tube 2 along knife face, open up on blade 23
There is the leakage hole 231 through blade 23, leaks out the moisture contained in tamper from leakage hole 231.
When the utility model is used, two stabilizer blades 12 of support frame 1 to be fixed on to the two sides of sewer mouth, by outrigger shaft
212 are mounted on the lower end of fixing axle 211, and exntension tubs 25 are slid into the lower end of fixed cylinder 24, and sliding block 241 is made to enter fixing groove
In 252.Then according to the position of the depth adjustment loop bar 112 of sewer and limit assembly 14, dirt removing tube 2 is directed at sewer
Pipe, slide downward mounting plate 13 open motor, driving until the tamper in the lower end and sewer pipe of exntension tubs 25 offsets
Agitating shaft 21 rotates, and the blade 23 being fixed on agitating shaft 21 is rotated with it, cut to the tamper to deposit in sewer
Cleaning, the tamper for being cut into sheet is rotated with blade 23 to be entered in exntension tubs 25 along knife face.After the completion of cleaning, electricity is closed
Machine moves up mounting plate 13 by moving up loop bar 112 and limit assembly 14, and dirt removing tube 2 is with mounting plate 13 to moving up
It is dynamic, after sewer is left in the lower end of exntension tubs 25, dirt removing tube 2 is rotated, dirt removing tube 2 is tilted with respect to support frame 1, then rotates
Exntension tubs 25 return to sliding block 241 in sliding slot 251, push up exntension tubs 25, slide up the relatively fixed cylinder 24 of exntension tubs 25
Dynamic, the state of trash-removal device is as shown in figure 4, the tamper in dirt removing tube 2 is fallen.When being stored to trash-removal device, upwards
Exntension tubs 25 are slided, sliding block 241 is made to slide into the bottom end of sliding slot 251, remove outrigger shaft 212 from fixing axle 211, and to downslide
Dynamic loop bar 112, the volume of such trash-removal device just greatly reduce, are convenient for carrying and store.The utility model has the advantages of simple structure, behaviour
Facilitate, to the high-efficient of sewer decontamination.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
