The utility model relates to technical field of engineering machinery, relates in particular to a kind of concrete sprayer that is used for the hopper of concrete sprayer and uses this hopper.
Background technology
Available coagulation soil spraying machine is main with the straight-through rotor block formula spraying machine of malleation wherein by many kinds of form of structure.And the combining form according to hopper mainly comprises body vibration formula concrete sprayer and separate assembling concrete sprayer in the straight-through rotor block formula spraying machine.
The structure of body vibration formula concrete sprayer is as shown in Figure 1; Comprise on frame 18 and the frame 18 rotor block 3 that the pivot center that rotates assembling extends along the vertical direction; Frame 18 comprises respectively the hopper seat 2 and base 19 that the upper and lower end face with said rotor block 3 is sealed and matched; Hopper 1 is installed on the hopper seat 2, is connected with vibrating motor 6 on the hopper 1.Along the circumferential direction be distributed with concrete charging hole 2-1 on the hopper seat 2; Described base 19 is provided with the concrete discharge opening 19-1 that is used with said concrete charging hole 2-1; Hopper seat 2 and/or base 19 are provided with the relief hole that is used with said concrete charging hole 2-1 and concrete discharge opening 19-1; Concrete charging hole 2-1, concrete discharge opening 19-1 and relief hole are provided with along the rotation direction of rotor block 2 successively at interval; Be evenly equipped with the rotor material chamber 8 that when rotor block 2 rotates, is communicated with concrete charging hole 2-1, concrete discharge opening 19-1 and relief hole successively on the rotor block 2; Also be provided with the high pressure pore 2-2 corresponding on the hopper seat 2 with concrete discharge opening 19-1 upper-lower position; High pressure pore 2-2 is communicated with first source of the gas through tracheae, is communicated with discharge nozzle 4 on each concrete discharge opening 19-1, on discharge nozzle 4, is connected with to be used for gas transmission in it so that second source of the gas 11 that the pipe inner concrete is dispelled.10 expression powder accelerating admixtures add direction among the figure, part 7 expression concrete.
The structure of separate assembling concrete sprayer is as shown in Figure 2; Different with the structure of body vibration formula concrete sprayer is; The hopper 1 of powder combined type concrete sprayer comprises elevating hopper 1-1 and hopper 1-2; Wherein an elevating hopper 1-1 and a vibrating motor are in transmission connection, and hopper 1-2 is fixed on the frame.
The course of work of two kinds of concrete sprayers is all identical; The concrete that is about to stir is poured in the hopper 1 by batching mixer (or artificial spice and material loading); And get in the corresponding rotor material chamber 8 through charging hole 2-1; Rotor material chamber 8 rotates to concrete discharge opening 19-1 place with rotor block 2, and feed first compressed air this moment in the corresponding high pressure pore 2-2 of concrete discharge opening 19-1, and first compressed air is blown into discharge nozzle 4 with concrete by rotor material chamber 8; Second source of the gas 11 is introduced second compressed air once more in discharge nozzle 4, concrete is dispelled, quickens, suspends in discharge nozzle 4 and finally sprayed by discharge nozzle 4.The concrete operating principle of concrete sprayer is as shown in Figure 3: with hopper seat 2 and base 19 along being divided into six workspaces according to the different of function on the rotation direction of rotor block 2, comprising the normal pressure feed zone 12 that is communicated with outside atmosphere, material normal pressure seal area 13, high pressure discharge zone 14 are arranged, not having material high pressure sealing district 15, do not have material voltage discharging area 16 and do not have material seal area 17.The course of work is: normal pressure feed zone 12 is included on rotor block 3 rotation directions order and is provided for concrete and is full of the feeding section in respective rotor material chamber and the full segment that concrete has been full of respective rotor material chamber gradually; In normal pressure feed zone 12, concrete seven is filled it up with corresponding rotor material chamber 8 through feeding section and full segment in the rotation process of rotor block 3.→ rotor material the chamber 8 of filling concrete seven is rotated further with rotor block 2; When material normal pressure seal area 13 paramount pressure discharge districts 14 are arranged; In corresponding rotor material chamber 8, import first compressed air by high pressure pore 2-2, concrete seven gets into discharge nozzle 4 by corresponding rotor material chamber 8 under the first compressed-air actuated drive.→ corresponding rotor material chamber 8 rotates to material high pressure sealing district 15, has not had concrete in the rotor material chamber 8 at this moment, but has had gases at high pressure.→ corresponding rotor material chamber 8 continues to rotate to does not have material voltage discharging area 16, and rotor material chamber 8 is direct or indirect and atmosphere through relief hole, and the pressure in the rotor material chamber 8 releases.→ corresponding rotor material chamber 8 is continued to rotate to normal pressure feed zone 12 and fed in raw material, and accomplishes a circulation, and is so reciprocal.
In actual use,, improve its quick supporting characteristic, can reduce springback capacity that concrete seven sprays again and reduce cost, generally all need add the powder accelerating admixture in the concrete seven kind in order to increase one deck jet thickness that concrete seven sprays.The addition manner of existing powder accelerating admixture is divided into the normal pressure interpolation and high pressure adds two kinds.
Normal pressure adds general the employing manually of accelerating admixture and adds; Spill to the top of hopper inner concrete 7 for utilizing the special messenger constantly to clutch accelerating admixture in the practical implementation, the shortcoming of this addition manner is that labour intensity is big, cost is high, interpolation is inhomogeneous, human factor is bigger.Another kind is to adopt proportioning device constantly to be transported to the powder accelerating admixture top of hopper concrete seven.No matter but be to adopt manual work or adopt proportioning device in hopper, to be sprinkled into the powder accelerating admixture; All existing rotor material chamber 8 is filled up by concrete seven; The powder accelerating admixture that is in simultaneously in the respective rotor material chamber 8 with concrete seven does not seldom perhaps have; And then both mixing in discharge nozzle 4 that influence them, finally influence concrete rate of set.
High pressure adds the general isolated plant that adopts, and adopts pressure-air to break up the powder accelerating admixture of quantitatively output, utilizes line transportation in discharge nozzle, to mix with concrete, reach the purpose of even interpolation, but this addition manner need be equipped with special equipment.Relative complex, price cost height and operation inconvenience.
