Background
The underground engineering construction is closely related to factors such as engineering geology, hydrogeology, surrounding construction environment and the like, so a series of engineering problems which are easily caused during shield construction, such as boulders, lump stones, soil body deformation, uneven ground surface settlement and the like, are encountered during the tunneling process; on the other hand, the engineering geological conditions in various regions of China are complicated and changeable, and the properties of the geotechnical body engineering are different. Therefore, the problems of overlarge pressure of a soil chamber of the shield tunneling machine, damaged pipe pieces, overlarge torque of a cutter head, overlarge temperature difference between the inside and the outside of the cutter head, difficult slag discharging and the like are often encountered in shield construction.
In the construction of No. 6 subway projects of track traffic in Wuhan City, the pretreatment effect of the 13a stratum rock lumps directly influences the tunneling state and the construction cost of the shield tunneling machine. Therefore, it is necessary to conduct experimental investigation of 13a formation block pretreatment.
Before the pretreatment research of the blockstone, the blockstone needs to be subjected to multi-stage screening, and the multi-stage screening device is introduced in the scheme.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that exists among the prior art, and the screening plant for stone pretreatment that proposes, the utility model discloses a set up helical blade, can be with the aggregate swing out outside of the tubes, realize the limit screening limit ejection of compact, efficiency is higher.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a screening plant for stone preliminary treatment, the on-line screen storage device comprises a base, the base top is connected with the support, it is connected with two bearing shafts to rotate on the support, bearing shaft tip is connected with the output of motor, the motor is installed on the base, the outer lane cylinder has been erect on the bearing shaft, the outer lane cylinder has connected gradually outer lane screen pipe and center screen pipe through the support, the outer wall of outer lane screen pipe and center screen pipe is equipped with the sieve mesh, and the aperture of center screen pipe is greater than the aperture of outer lane screen pipe, driven ring gear has been cup jointed to the outer lane of outer lane cylinder, the epaxial drive gear corresponding with driven ring gear that has cup jointed of bearing, the outer lane cylinder, outer lane screen.
Preferably, the bearing shaft is further sleeved with a limiting wheel, the outer ring of the outer ring roller is sleeved with two limiting baffle rings, and the limiting wheel is located between the two limiting baffle rings.
Preferably, both sides of the limiting wheel are embedded with balls.
Preferably, the center screen, the outer screen and the outer drum decrease in length in sequence.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, the motor passes through the load axle and drives drive gear and rotate, drive gear and driven ring gear meshing drive outer lane cylinder, center screen pipe and outer lane screen pipe rotate, and during the central screen pipe was sent into to the aggregate, the aggregate was rotating the in-process, constantly filters, and the particle diameter is less gets into outer lane screen pipe and outer lane cylinder in proper order, realizes the screening, at this in-process, because helical blade's existence, can revolve out the outside of the pipe with the aggregate, realizes the limit screening limit ejection of compact, and efficiency is higher.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a cross-sectional view of the outer-ring roller.
In the figure: the screen pipe comprises an outer ring screen pipe 1, a center screen pipe 2, a bearing shaft 3, a driving gear 4, a base 5, a limiting wheel 6, a support 7, a limiting baffle ring 8, a driven gear ring 9, an outer ring roller 10, a helical blade 11 and a support 12.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a screening plant for stone pretreatment, including base 5, base 5 top is connected with support 7, it is connected with two bearing axle 3 to rotate on support 7, the bearing axle 3 tip is connected with the output of motor, the motor is installed on base 5, bearing axle 3 is put on the shelf and is equipped with outer lane cylinder 10, outer lane cylinder 10 has connected gradually outer lane screen pipe 1 and center screen pipe 2 through support 12, the outer wall of outer lane screen pipe 1 and center screen pipe 2 is equipped with the sieve mesh, and the aperture of center screen pipe 2 is greater than the aperture of outer lane screen pipe 1, driven ring 9 has been cup jointed to the outer lane of outer lane cylinder 10, bearing axle 3 is last to cup joint drive gear 4 corresponding with driven ring 9, outer lane cylinder 10, outer lane screen pipe 1 and center screen pipe 2 inner wall all are connected with helical blade 11, the motor passes through the wire and is connected.
Still cup jointed spacing wheel 6 on the bearing shaft 3, two spacing fender rings 8 have been cup jointed to the outer lane of outer lane cylinder 10, and spacing wheel 6 is located between two spacing fender rings 8, prevents that outer lane cylinder 10 horizontal direction from appearing sliding.
