The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Referring to shown in Fig. 1 to 7, the utility model provides a kind of spiral sprayer for concrete, comprise base 4, shower nozzle 11, and be installed on the motor on base 4, described base 4 is skiing board structure, the material pushing box 2 that carries worm screw is installed on base 4, on one end sidewall of material pushing box 2, offer feeding mouth, the other end of material pushing box 2 is provided with discharging opening, the lower end of material pushing box 2 is provided with for supporting the supporter 5 of material pushing box 2, on the discharging opening of material pushing box 2, be provided with material pushing box support 6-2, the feeding mouth end of described material pushing box 2 is provided with the motor rotating for rotating the worm screw of material pushing box 2, motor is installed on base 4 by motor bracket 3, on the discharging opening of material pushing box 2, by tumbler, be connected with conveying pipeline 12, the other end of conveying pipeline 12 is connected with the feeding mouth 10 of shower nozzle 11, the transmission device that shower nozzle 11 is rotated is installed on the sidewall of shower nozzle 11, in shower nozzle 11, be provided with impeller 28, the rotating shaft of motor is connected with transmission device, and the rotating shaft of motor, through after shower nozzle 11 outer walls, is connected with impeller 28, on the sidewall of shower nozzle 11, offer and accelerating admixture pipeline.
Described tumbler comprises and is installed on the ring block 13 that material pushing box 2 discharging openings go out, and ring block 13 clamps mutually with conveying pipeline 12, and the two ends of ring block 13 are respectively arranged with front catch 14 and rear catch 15.
Described transmission device comprises driving gear and the driven gear being meshed with driving gear, and driven gear is fixed on shower nozzle 11 outer walls, and driving gear is fixed on machine shaft, after driving gear rotates, drives driven gear to rotate.
This practical servicing unit that also comprises, described servicing unit comprises the lance holder 6-1 being installed on base 4, is provided with horizontal support 25 on pipe holder 6-1, and horizontal support 25 centers offer running-on 24, and machine shaft is sheathed in running-on 24.
The course of work of the present utility model and principle:
By by the concrete conveyance being stirred to the material pushing box 2 that middle worm screw is housed.Under the drive of CD-ROM drive motor, worm screw is pushed into compound to be connected in conveying pipeline 12.Compound enters in shower nozzle 11 through conveying pipeline.Because compound enters from the outer edge of impeller, therefore impeller is under the driving of CD-ROM drive motor, compound is tangentially hit.Shower nozzle 11 can be realized 360 ° of rotations under CD-ROM drive motor drives by transmission gear, and then has realized the effect of 360 ° of injections of concrete sprayer.
In the utility model, shower nozzle 11, comprises two parts, and a part is impeller, and a part is shell.Consider that this equipment is to utilize the tangential force of impeller that concrete is ejected, therefore therefore in order to guarantee that its charging aperture enters along the tangential direction of impeller the principle adopting as shown in Figure 5 all the time.Be that shower nozzle 11 rotations drive the conveying pipeline 12 that rear side joins with it to rotate along shower nozzle 11 axis, can avoid like this conveying pipeline because 360 °, shower nozzle rotates caused pipeline wrapping phenomenas.
In order to realize the demand of 360 ° of injections, tumbler is: at the outside of small radius conveying pipeline 12 welding thickened ring-shaped piece 13, according to the size of small radius welding ring block, determine again afterwards radius size and the distance of front catch 14, rear catch 15, front catch 14 is fixed by spiral interface with small radius conveying pipeline, and rear catch 15 is fixed with large radius conveying pipeline by spiral interface.Present two aspects of this device acting body: before the first, catch 14 can play and prevent that concrete mixture from entering into conveying pipeline 12 socket finedraws; It two is to realize inner side small radius conveying pipeline 12 to rotate and the motionless effect of the large radius conveying pipeline in outside vertically.
Accelerating admixture pipe is linkage vertically, and intermediate junction device and accelerating admixture pipe are fixed, and shower nozzle front end axle can rotate around its axis.Consider that in addition intermediate propeller shaft there will be connector sealing problem when rotating conveying pipeline, in conjunction with present more existing processing methods, to between the inner side of connection running-on and second(-)motion shaft outside, add one section of rubber leather hose adapting with conveying pipeline pipe thickness, the inner side bore of rubber leather hose should be slightly less than the diameter of intermediate propeller shaft, can be close to intermediate propeller shaft, rubber leather hose outside should be according to the size that connects bore, its thickness is carried out to suitable design, make it meet the requirement of being close to outside connector wall.
For the utility model can be pulled in culvert, therefore adopt skiing board structure, be base, this base device is mainly comprised of 2 slide plates and a gripper shoe, and every slide plate one end is the certain angle of perk all, in case be absorbed in earth or deposit.On each slide plate, be to have hawser, by constructor, at hole, with hawser, draw carriage.
Effect of the present utility model:
1, save manpower, improved workman's operating environment.
2, can adapt to preferably the narrow and small structure in inner space and adopt sprayed mortar to reinforce, be also a kind of innovation to original concrete sprayer simultaneously.And shower nozzle can realize 360 ° of rotations, make concrete in small space spray more even.
3, the utility model concrete sprayer fuselage is light and handy, flexible, is convenient to field carrying and construction application.
4, the manufactured materials of the utility model concrete sprayer is comparatively common, cheap.The power set that MODERN SHOTCRETING MACHINES adopts are that motor drives, and the original compressed air-driven of replacement, has reduced cost.
