Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
See shown in Fig. 1 to 7, the invention provides a kind of spiral sprayer for concrete, comprise base 4, shower nozzle 11, and the motor be installed on base 4, described base 4 is skiing board structure, base 4 is provided with the material pushing box 2 carrying worm screw, one end sidewall of material pushing box 2 offers 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 the supporter 5 for supporting material pushing box 2, the discharging opening of material pushing box 2 is provided with material pushing box support 6-2, the feeding mouth end of described material pushing box 2 is provided with the motor of the worm screw rotation for rotating material pushing box 2, motor is installed on base 4 by motor bracket 3, the discharging opening of material pushing box 2 is connected with conveying pipeline 12 by tumbler, the other end of conveying pipeline 12 is connected with the feeding mouth 10 of shower nozzle 11, the sidewall of shower nozzle 11 is provided with the transmission device that shower nozzle 11 is rotated, impeller is provided with in shower nozzle 11, the rotating shaft of motor is connected with transmission device, and the rotating shaft of motor is through after shower nozzle 11 outer wall, is connected with impeller, the sidewall of shower nozzle 11 offers accelerating admixture pipe 1.
Described tumbler comprises the ring block 13 being installed on material pushing box 2 discharge outlet, and ring block 13 clamps with conveying pipeline 12 phase, and the two ends of ring block 13 are respectively arranged with front catch 14 and rear catch 15.
The driven gear that described transmission device comprises driving gear and is meshed with driving gear, driven gear is fixed on shower nozzle 11 outer wall, and driving gear is fixed on machine shaft, after driving gear rotates, drives driven gear to rotate.
Basis is practical also comprises servicing unit, and described servicing unit comprises the lance holder 6-1 be installed on base 4, lance holder 6-1 is provided with horizontal support 25, and horizontal support 25 center offers running-on 24, and machine shaft is sheathed in running-on 24.
The course of work of the present invention and principle:
By by the concrete conveyance be stirred to the material pushing box 2 that middle worm screw is housed.Under the drive of CD-ROM drive motor, compound is pushed into and is connected in conveying pipeline 12 by worm screw.Compound enters in shower nozzle 11 through conveying pipeline.Because the outer edge of compound from impeller enters, therefore impeller is under the driving of CD-ROM drive motor, is tangentially hit by compound.Shower nozzle 11 can realize 360 ° of rotations under CD-ROM drive motor is driven by transmission gear, and then achieves the effect of concrete sprayer 360 ° injection.
In the present invention, shower nozzle 11, comprises two parts, and a part is impeller, and a part is shell.Consider that this equipment utilizes the tangential force of impeller to be gone out by concrete ejection, therefore in order to ensure that its charging aperture enters along the tangential direction of impeller all the time therefore adopts principle as shown in Figure 3,4.Namely the conveying pipeline 12 that shower nozzle 11 connects with it on rear side of rotating and driving rotates along shower nozzle 11 axis, can avoid the pipeline wrapping phenomena of conveying pipeline caused by 360 °, shower nozzle rotates like this.
In order to realize 360 ° of demands of spraying, tumbler is: at the outside of small radius conveying pipeline 12 welding thickened ring-shaped block 13, the size of foundation small radius welding ring block determines radius size and the distance of front catch 14, rear catch 15 more afterwards, front catch 14 and small radius conveying pipeline are by spiral interface consolidation, and rear catch 15 is by spiral interface and large radius conveying pipeline consolidation.Present two aspects of this device acting body: before the first, catch 14 can play and prevent from concrete mixture from entering into conveying pipeline 12 being socketed finedraw; It two is realize the effect that inner side small radius conveying pipeline 12 rotates vertically and outside large radius conveying pipeline is motionless.
Accelerating admixture pipe linkage vertically, intermediate junction device and accelerating admixture pipe consolidation, shower nozzle front end axle can rotate around its axis.Consider that intermediate propeller shaft there will be connector sealing problem when rotating conveying pipeline in addition, in conjunction with more existing processing methods now, one section of rubber leather hose adapted with conveying pipeline pipe thickness is added between outside the inner side of connection running-on and second(-)motion shaft, the inner side bore of rubber leather hose should be slightly less than the diameter of intermediate propeller shaft, intermediate propeller shaft can be close to, should according to the size connecting bore outside rubber leather hose, suitable design is carried out to its thickness, makes it meet the requirement being close to outside connector wall.
In order to make the present invention can pull in culvert, therefore to adopt skiing board structure be base, and this base device is primarily of 2 pieces of slide plates and one piece of gripper shoe composition, and every block slide plate one end all tilts certain angle, in case be absorbed in earth or deposit.Each slide plate is have hawser, draws carriage by constructor at hole hawser.
Effect of the present invention:
1, save manpower, improve the operating environment of workman.
2, can adapt to the narrow and small structure in inner space preferably adopts sprayed mortar to reinforce, and is also reform the one of original concrete sprayer simultaneously.And shower nozzle can realize 360 ° of rotations, makes concrete ejection in small space more even.
3, concrete sprayer fuselage of the present invention is light and handy, flexible, is convenient to field carrying and construction application.
4, the manufactured materials of concrete sprayer of the present invention is comparatively common, cheap.The power set that MODERN SHOTCRETING MACHINES adopts are that motor drives, and the original compressed air-driven of replacement, reduces cost.
