Abstract
The utility model is a kind of for the concrete ejecting device in support engineering, by pulp-entering pipe, be uniformly mixed pipe, stable pipe, nozzle form, pulp-entering pipe is connected to and is uniformly mixed pipe, be uniformly mixed pipe design and be divided into two parts, a part is that to tilt be the surfaces of revolution of 45 °, another part is stirring rod, is uniformly mixed between pipe and overcoat and has built-in steel bushing district; At nozzle, place is provided with valve, and valve is made up of valve head, valve sheet, and valve sheet is circular arc.
Description
Technical field
The utility model relates to concrete shower nozzle, is related specifically to the concrete shower nozzle spraying the use of concrete process in underground support engineering.
Background technology
In support engineering, particularly in underground mining support engineering or side slope protection engineering, concrete just spray or multiple spray all to be carried out.Wherein in spray concrete process, what adopt at present is be placed in spray machine by water, cement, stone mixing, adds compressed air and accelerator, be ejected in a mask form a kind of overcoat by shower nozzle in spray machine pipeline.But because mixture can not fully mix in the duct, so springback capacity can be caused to increase and produce dust when spraying, particularly in moist spurting craft, owing to being the mode adopting the siccative of mixing directly to mix rear ejection with water before shower nozzle, so material can not be made fully to mix, it is also the reason that springback capacity increases; In addition, our normally used shower nozzle, at nozzle place, does not arrange the valve controlling flow, so in spray concrete process, because spray concrete face may exist the distance in out-of-flatness or spray concrete face, well can not grasp the pressure size of spray concrete.It is on May 30th, 2012 in the day for announcing, notification number is CN202238411U, utility model name is called in the utility model application file of " concrete spray head ", provide a kind of concrete spray head, it arranges the surfaces of revolution only by mixed zone, allow mixture play stirring action by rotation, but the stirring of this mode to mixture is limited, well can not plays immixture.
Summary of the invention
High in order to solve the rebound degree occurred in support engineering concrete ejection process, the problem that Dust Capacity is large, devises a kind of concrete ejecting device, carries out concrete injection work by this device.
This is practical is a kind of ejecting device for concrete ejection, by pulp-entering pipe, be uniformly mixed pipe, stable pipe, nozzle form, pulp-entering pipe is connected to and is uniformly mixed pipe, wherein be uniformly mixed pipe design and be divided into two parts, a part is the surfaces of revolution, another part is stirring rod, is uniformly mixed between pipe and overcoat and has built-in steel bushing district; Nozzle place is provided with valve, and valve is made up of valve head, valve sheet, and valve sheet is circular arc.
As improvement, the material of this practical employing is lightweight Steel material.
As improvement, in mixing tube, between inner sleeve and overcoat, be designed with steel ball; In mixing tube, the surfaces of revolution of front portion design is inclination 45 °, and rear portion is set to stirring rod and is designed to cylinder.
As improvement, stable pipe is set between mixed zone and nozzle.
As improvement, at nozzle place, arrange valve, valve works by valve sheet, and valve sheet is arc-shaped.
The beneficial effects of the utility model are: slurries enter mixed zone by pulp-entering pipe, and slurries can, under the effect of the surfaces of revolution and stirring rod, make slurries fully mix; At nozzle place, by arranging valve, the size of outlet can be adjusted, controlling the pressure of pulp thus; And reach the object reducing rebound degree and reduce amount of dust.

Reference numeral:
Wherein overcoat 1, pulp-entering pipe 2, steel ball 3, the surfaces of revolution 4, is uniformly mixed pipe 5, stirring rod 6, and built-in steel bushing district 7, stablizes pipe 8, nozzle place 9, valve 10, valve head 11, valve sheet 12, spout 13.
Detailed description of the invention
With reference to the accompanying drawings 1: the utility model by pulp-entering pipe (2), be uniformly mixed pipe (5) and nozzle place (9) form, pulp-entering pipe (2) connection is uniformly mixed pipe (5), wherein be uniformly mixed in pipe (5), be divided into two parts, as Fig. 2, front portion is the surfaces of revolution (4); If Fig. 3 rear portion is stirring rod (6), built-in steel bushing district (7) is there is between pipe and overcoat (1), be built-in with steel ball (3), slurries enter through the surfaces of revolution (4) and drive whole inner sleeve to rotate, and stirring rod (6) also can rotate stirring simultaneously.As Fig. 4, in nozzle place (9), arrange valve (10), valve is made up of valve head (11) and valve sheet (12).
As improvement, be uniformly mixed in pipe (5), between design steel bushing district (7), be built-in with steel ball (3), front portion is the surfaces of revolution (4) of inclination 45 °, and rear portion is cylinders agitate rod (6).
As improvement, in nozzle place (9), arrange valve (10), valve sheet (12) is in circular arc.
