Abstract
The utility model provides a fully wet type concrete spraying machine and is composed of a shocking material supplying device, a water supplying device, a screw rod pump spraying device and a running device. The fully wet type concrete spraying machine is characterized in that a screw rod pump is a single layer stator structure and the running device adopts a circle wheel. The fully wet type concrete spraying machine has the advantages of convenient operation, good screw rod manufacturability, long service life and low dust concentration and is widely used in various building surfaces for spraying the concrete.
Description
The utility model relates to the building machinery technical field.
At present, the used spraying machine of sprayed mortar mostly is rotor-type and drum type dry type concrete spraying machine, adopts wind to send siccative, pump moving component quick abrasion, and dust concentration is up to 1.806g/m
3, serious harm operating personnel's health, the dry spraying machine concrete strength is low simultaneously, and the resilience waste is big, and labor intensity of operating staff is big; In recent years, produced the full wet type concrete sprayer abroad, VELMATSB3-3 machine as the production of West Germany Motomburo company, there are the following problems for this machine: (1) screw pump stator is the double-level-metal structure, processing difficulties, the softening processing time of screw rod is long, the residual harness height, manufacturability is bad, and the screw rod life-span is shorter.(2) water system adopts secondary to supply water, and incompatibility is constructed under the hydraulic pressure labile state at home, and concrete water-cement ratio control is unstable.(3) running gear is the skid formula, inconvenient walking.(4) volume is big, small bore construction in the incompatibility.
The purpose of this utility model provides a kind of good manufacturability, and the life-span is long, and dust concentration is low, and resilience is little, can control water/binder ratio, and walking is convenient, the novel full wet type concrete sprayer of wide accommodation.
Technical solution of the present utility model is, the vibrations feeding device is made up of reciprocating sieve (5), hopper (6), mixing drum (4), feed bin (3), special character of the present utility model is that screw pump (2) adopts the single-layer stator structure, water supply installation adopts three grades of water supply, running gear adopts circle wheel (7), establishes accelerating admixture inlet (9) on nozzle (1).The inwall of the stator (11) of screw pump (2) is processed into screw thread and closely contacts with elastomer stator (13), elastomer stator (13) inwall is and the supporting spirality of screw rod (12) profile, assurance has certain feed space, and screw rod (12) makes concrete clamp-on the entrance of nozzle (1).The material of screw rod (12) adopts the remodeling antifriction cast iron.
Water supply installation is by water valve (14), (15), (16), (17), drencher (18) is formed, water valve (16) is an one-level, water valve (15) is a secondary, water valve (14) is three grades, press water source hydraulic pressure size, partly or entirely open one, two, three water valve (16), (15), (14), guarantee that the interior concrete water-cement ratio of mixing drum (4) is in 0.58～0.60 scope, if the concrete in the feed bin (3) is dried partially, water valve (17) is opened, directly sprayed water to feed bin (3) with drencher (18).
Go up installation circle wheel (7) at base (8), all parts of complete machine are installed on the base (8), complete machine can be walked flexibly.
Because the stator (11) of screw pump (2) adopts single layer structure, so easy to process, stator (11) inwall is processed into screw thread, guarantees that stator (11) closely contacts with elastomer stator (13), does not produce axial displacement during work, and the materials flow continuity is good.Because screw rod (12) adopts the anti-cast iron of remodeling, so its processing technology is good, the screw rod life-span prolongs.
Because water supply installation adopts three grades to supply water and directly feed bin (3) is sprayed water with drencher (18), thereby guarantees concrete water/binder ratio between 0.58～0.60, and concrete intensity is guaranteed.
Because circle wheel (7) is housed on the base (8), construct so easily machine is moved on to the appropriate location, machine volume reduces simultaneously, small bore construction in being suitable for.
Owing to accelerating admixture is sprayed onto working face with concrete,, reduces resilience so improve concrete strength.
The utility model is compared with dry spraying machine, after tested correction data such as following table.
| Spray intensity | Rebound degree | Dust concentration | |
| Dry spraying machine | 30～50％ | 100mg／m | |
| The wet shot machine | Improve 30～40% than doing spray | 10％ | ＜15mg/m |
The utility model and external product compare, after tested correction data such as following table.
Following accompanying drawing has been described embodiment of the present utility model.
