The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
As shown in Figure 2; The concrete spraying machine of the utility model; Comprise at least two shower nozzles 10, concrete pumping mechanism 11, transmission and concrete transmission pipe assembly 7, accelerating admixture feed system 4 and accelerating admixture hose assembly 6; The input of accelerating admixture hose assembly 6 is communicated with accelerating admixture feed system 4 discharging openings; The input of transmission and concrete transmission pipe assembly 7 is communicated with the discharging opening of concrete pumping mechanism 11, and the output of transmission and concrete transmission pipe assembly 7 and accelerating admixture hose assembly 6 all is connected with the input port of each shower nozzle 10.Through adopting two with upper nozzle 10, the pressure at each shower nozzle 10 place is reduced, the workman can 10 pairs in hand steered shower nozzle be sprayed by spray plane, and working strength of workers reduces greatly.
In the present embodiment, shower nozzle 10 is two.The input port of two shower nozzles 10 connects sebific duct 9 through one respectively and is connected with two outlets of transmission and concrete transmission pipe assembly 7 outputs, makes things convenient for each shower nozzle 10 and moves with respect to what receive spray plane, can expand jet space.Transmission and concrete transmission pipe assembly 7 is preferably can high pressure resistant, anti abrasive steel pipe.
In the present embodiment, concrete pumping mechanism 11 for can be used on carry out concrete pumping under the coal mine drag pump or filling pump.Accelerating admixture feed system 4 comprises accelerating admixture case 41, accelerating admixture metering system 42 and air motor 43; The first compressed air input pipe 1 of air motor 43 is provided with compressed air control ball valve 2; Air motor 43 is used to drive accelerating admixture metering system 42 and obtains accelerating admixture from accelerating admixture case 41, to drive the supply of accelerating admixture.Accelerating admixture metering system 42 is used to control the quantity delivered of accelerating admixture, and accelerating admixture hose assembly 6 is used to carry accelerating admixture and compressed air.The input of accelerating admixture hose assembly 6 detachably is communicated with the discharging opening of accelerating admixture metering system 42; The output of accelerating admixture hose assembly 6 is provided with two and is in charge of; Be in charge of respectively for two and detachably be communicated with two outlets of transmission and concrete transmission pipe assembly 7 outputs, the input port of each shower nozzle 10 all is communicated with the output of accelerating admixture hose assembly 6 through the output of transmission and concrete transmission pipe assembly 7.Be in charge of for two of accelerating admixture hose assembly 6 and be equipped with the second compressed air input pipe 8, on the second compressed air input pipe 8, be provided with compressed air control ball valve 2.Concrete pumping mechanism 11 delivers to elephant trunk assembly 7 with concrete pump, and mixes with accelerating admixture in its end, receives spray plane by the compressed air differentiation after shower nozzle 10 is ejected into again.
Operating principle: during construction; When treating the next concrete of concrete pumping mechanism 11 pumpings soon to shower nozzle 10; Open the compressed air control ball valve 2 on the first compressed air input pipe 1 and the second compressed air input pipe 8, at this moment, air motor 43 starts; Drive accelerating admixture metering system 42 and obtain accelerating admixture from accelerating admixture case 41; Mix with concrete in the output end of transmission and concrete transmission pipe assembly 7 via accelerating admixture hose assembly 6 backs, and under the compressed air effect, concrete is broken up, be sprayed onto via connection sebific duct 9 and shower nozzle 10 again and receive spray plane.Because adopt two shower nozzles, the reaction force at the spout place of each shower nozzle 10 reduces greatly during injection, the workman can 10 pairs in hand steered shower nozzle be sprayed by spray plane.
Equal ability quickly dismantled makes its conveniently moving in roadway quick between each parts in the utility model.
In other embodiments, the quantity of shower nozzle 10 can not be restricted to two, can adopt the many shower nozzles greater than two, as long as can realize reducing the pressure at shower nozzle place.When adopting greater than many shower nozzles of two; Transmission and concrete transmission pipe assembly 7 is provided with a plurality of outlets with the output of accelerating admixture hose assembly 6; And both export volumes are corresponding with the quantity of shower nozzle; And be provided with the second compressed air input pipe 8 at the output of each accelerating admixture hose assembly 6; And on the second compressed air input pipe 8, be provided with compressed air control ball valve 2, thus realize the jeting effect of many shower nozzles, and the pressure at pressure single shower nozzle more of the prior art place at each shower nozzle 10 place has significantly and reduces.
