Embodiment
There is the helix transporting device of filtering slurry function to include hopper 1, power transmission shaft 2 and blade 3 for this, pass through in hopper 1
Symmetrically arranged bearing block 4 is provided with power transmission shaft 2, and spiral is provided with blade 3 on power transmission shaft 2, before promoting material at work
OK.The section of hopper 1 of the helix transporting device is U-shaped body, and cover plate 5 is provided with hopper 1, air-vent 8 is evenly equipped with cover plate 5.
Charging aperture 6 is provided with the top of one end of hopper 1, the other end bottom of hopper 1 is provided with discharging opening 7.One end extension of power transmission shaft 2
To the outer front end of hopper 1, extend to sealing on the power transmission shaft 2 of the outer front end of hopper 1 and swivel head 9 is housed, to be used at work
Connect vacuum plant；So that negative pressure is formed in hopper 1.The other end of power transmission shaft 2 extends to the afterbody outer end of hopper 1, extends to
The power transmission shaft 2 of the afterbody outer end of hopper 1 passes through shaft coupling 10 and power motor（Do not show in figure）Connection；With band movable vane piece at work
3 rotate.
The power transmission shaft 2 of the helix transporting device is hollow tubular body, and the power transmission shaft 2 for closing on the one end of shaft coupling 10 is closure
Shape, to ensure suction function in hopper 1；Filter bores are evenly equipped with the circumference of power transmission shaft 2 in hopper 1.With filtering in power transmission shaft 2
Hole corresponds to shape and is provided with wire-wrapped screen 11.Sealing ring 12 is provided between the both ends termination of wire-wrapped screen 11 and the inwall of power transmission shaft 2, with
Prevent material from leakage occur between wire-wrapped screen 11 and power transmission shaft 2 in the course of the work.One end termination installation of wire-wrapped screen 11
There is scraper 13.
When there is the helix transporting device of filtering slurry function to work for this, drilling mud is entered in feed chute 1 by charging aperture 6,
