Description
Technical field
The present invention relates to environmental sanitation machinery technology more particularly to a kind of sweeper nozzle structures and sweeper.
Background technique
Sweeper passes through brush during the work time and pavement garbage is delivered near nozzle structure by nozzle, is being centrifuged
Under the swabbing action of blower, the mixture for being mingled with rubbish and water enters in the garbage collection box of sweeper by nozzle structure,
Complete the cleaning process of pavement garbage.Key operation component of the nozzle structure as sweeper, structure type directly influence
The sweeping efficiency and operation effectiveness of sweeper.
Nozzle structure generally comprises suction inlet, suction pipe and transition structure at present, and suction pipe and transition structure are generally all perpendicular to ground
Face arrangement, it is higher and non-adjustable from the ground, and transition structure volume and changes of section gradient are bigger than normal.
Above structure there are the problem of are as follows: 1) suction pipe and transition structure be easy to cause gas-flow resistance bigger than normal not perpendicular to ground
It is picked up conducive to the suction of rubbish；2) nozzle structure terrain clearance is high, and suction nozzle cavity volume is larger, and internal negative pressure variable gradient is big, right
The suction on ground is weaker, is unfavorable for picking up the suction of ground small garbage particle；3) transition structure volume and changes of section gradient are inclined
It is easy to cause suction nozzle cavity inside Velocity Profiles uneven greatly, there are many low speed and eddy regions, are unfavorable for rubbish
Suction is picked up.
Due to ground refuse with fine sand gravel, rubble grain, dust be smaller in equal volume, based on the biggish particle of density, such rubbish
