To reach above-mentioned purpose, the utility model employs following technical proposal：This double helix screening machine includes staving, institute
Drive shaft is provided with the staving stated, described drive shaft is connected with vibrator, and Spiral distribution has screen cloth spiral plate in drive shaft,
If offering dry sieving hole on described screen cloth spiral plate, edge portion and the inner wall of barrel of screen cloth spiral plate fit.
In above-mentioned double helix screening machine, there is described screen cloth spiral plate screening hole portion to be divided into screening portion, screen cloth spiral shell
Part of the rotating plate without screening hole is collection portion.
In above-mentioned double helix screening machine, described screening portion and collection portion are arranged at intervals.
In above-mentioned double helix screening machine, if described screen cloth spiral plate includes dry sieving spiral scoreboard, adjacent sieve
Gathering screw plate is provided between point spiral scoreboard.
In above-mentioned double helix screening machine, described screening spiral scoreboard and gathering screw plate are fixed with drive shaft and connected
Connect, sieve spiral scoreboard and screening space, gathering screw are formed between the gathering screw plate on the screening spiral scoreboard top
Plate and form collection space between the screening spiral scoreboard on the gathering screw plate top.
In above-mentioned double helix screening machine, described screening space and the longitudinally spaced setting of collection space.
In above-mentioned double helix screening machine, positioned at drive shaft topmost to sieve spiral scoreboard, positioned at drive shaft most
Bottom for gathering screw plate.
In above-mentioned double helix screening machine, the top of described staving has charging aperture, and the bottom of staving has discharging
Mouthful.
Compared with prior art, it is the advantages of this double helix screening machine：Utilize spiral rotating, the spiral of same widths
Screening chute can produce longer effective chute length, and identical collection width floor space is small, and collection efficiency is high, can be continuous
Screen target ore particle.

Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the sectional view of embodiment 1 provided by the utility model.
Fig. 2 is sectional block diagram provided by the utility model.
Fig. 3 is top view provided by the utility model.
Fig. 4 is the sectional view of embodiment 2 provided by the utility model.
In figure, staving 1, drive shaft 2, vibrator 3, screen cloth spiral plate 4, screening hole 5, screening portion 7, collection portion 8, screening spiral shell
Revolve scoreboard 9, gathering screw plate 10, screening space 11, collection space 12.
Embodiment
It is the specific embodiment of utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
Embodiment 1
As Figure 1-3, this double helix screening machine includes staving 1, and drive shaft 2, drive shaft 2 and vibration are provided with staving 1
Device 3 is connected, and Spiral distribution has screen cloth spiral plate 4 in drive shaft 2, if offering dry sieving hole 5, screen cloth on screen cloth spiral plate 4
The edge portion of spiral plate 4 fits with the inwall of staving 1.Using spiral rotating, the screw sieving chute of same widths can produce
Longer effective chute length, identical collection width floor space is small, and collection efficiency is high, can be with step sizing target ore particle.
Wherein, if screen cloth spiral plate 4 includes dry sieving spiral scoreboard 9, it is provided with and collects between adjacent screening spiral scoreboard 9
Spiral plate 10.Screening spiral scoreboard 9 and gathering screw plate 10 are fixedly connected with drive shaft 2, sieve spiral scoreboard 9 and positioned at this
Sieve and screening space 11 is formed between the gathering screw plate 10 on the top of spiral scoreboard 9, gathering screw plate 10 and positioned at the collection spiral shell
Collection space 12 is formed between the screening spiral scoreboard 9 on the top of rotating plate 10.Screening space 11 and collection space 12 is longitudinally spaced sets
Put.It is gathering screw plate 10 positioned at the foot of drive shaft 2 positioned at the topmost of drive shaft 2 to sieve spiral scoreboard 9.Staving 1
Top there is charging aperture, the bottom of staving 1 has discharging opening.
The extensional vibration of drive shaft 2 is driven when vibrator 3 drives, so as to drive the up-down vibration of screen cloth spiral plate 4.From staving
1 upper end charging aperture pan feeding, slag or ore pulp move after first layer entrance along downward spiral.In the presence of vibration, mesh
Dimensioning little particle flow to next layer by the screening hole 5 sieved in spiral scoreboard 9.Due to fraction slurries also by screening hole 5,
Under fraction slurries effect, little particle flows along gathering screw plate 10.Target little particle is finally from the end of gathering screw plate 10
Flow out and collect in end.Reclaimed more than target size particle slag from screen cloth spiral plate 4.
