Abstract
The invention relates to a building construction device, in particular to a cement mixer which carries out cement grouting operation to a reserved bellow pore channel after stretching the reinforcing steel bar in a reinforced concrete structure. The cement mixer mainly comprises a mixing drum which is provided with a motor and a stock outlet, the motor is connected with a vertical axis in the mixing drum, and the vertical axis is provided with a group of mixing blades and two groups of mixing blades. As a group of mixing blades are added on the basis of one group of mixing blades in the prior art, the cement can be mixed fully and evenly in the mixing drum, thus meeting the demand that the water cement ratio of the cement used for grouting is about 0.4 in the national construction specifications.
Description
Technical field
The present invention relates to a kind of construction implement, especially relate to a kind of cement mixer of after the reinforced bar stretching in the reinforced concrete structure is finished, the bellows duct of reserving being implemented the grout injection operation.
Background technology
At present, for the reinforcing bar of the bonded prestress in the prestressed concrete construction, after finishing, reinforced bar stretching needs the grout injection operation is implemented in the bellows duct of reserving.In order to ensure carrying out smoothly and grouting quality of grouting, China's job specfication requires grouting to be about 0.4 with the ratio of mud of cement mortar, but existing mixing plant is limit because of its structure, there is the work blind area in its mixing speed than the stirring vane in slow and the mixing drum in mixing drum, make cement mortar can not carry out fully, stir uniformly, so can't satisfy the interior cement mortar of the requirement of above-mentioned job specfication, particularly mixing drum near particularly serious under the fully loaded situation.
Summary of the invention
Technical problem to be solved by this invention provides a kind of prior art defective of overcoming.The technical scheme that the present invention solves its technical problem employing is: a kind of cement mixer, it comprises that mainly mixing drum is provided with motor, grout outlet, motor connects the vertical pivot in the mixing drum, it is one group stirring vane that vertical pivot is provided with at least 3, and its axis direction of vertical pivot upper edge, relative one group of stirring vane are provided with another group stirring vane.The present invention increases by one group of stirring vane again on the basis of one group of stirring vane of prior art, stirring vane is generally 3 every group, spacing between the phase place setting of can staggering between two groups of stirring vanes up and down on the vertical pivot, two groups of stirring vanes is about 1/3 of mixing drum height.Technical problem to be solved by this invention also can further be solved by following technical solution: the angle between stirring vane and the horizontal plane is 20 °～40 °; Angle between stirring vane and the horizontal plane is 30 °, and the rotating speed of motor of the present invention is 180～200 rev/mins, and motor also can provide torque to vertical pivot after reductor slows down.The present invention is owing to adopt technique scheme, on the basis of one group of stirring vane of prior art, increased by one group of stirring vane, make cement mortar in mixing drum by full and uniform stirring, satisfied China's job specfication and required grouting to be about 0.4 requirement with the ratio of mud of cement mortar.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiments of the invention the present invention is described in further detail:
Accompanying drawing is a structural representation of the present invention.
With reference to accompanying drawing.Mixing drum 1 of the present invention is provided with motor 2, grout outlet 3, the vertical pivot 4 that motor 2 connects in the mixing drum 1, and vertical pivot 4 is provided with stirring vane 5.
The specific embodiment
Embodiment 1: with reference to accompanying drawing.In mixing drum, inject edible pipeline-used water (running water) and cement, when motor is worked, drive vertical pivot and drive the stirring vane rotation through vertical pivot, because of the two groups of stirring vanes up and down on the vertical pivot stir water in the mixing drum and cement simultaneously, water and cement are made it to become cement mortar by full and uniform stirring, cement mortar after the stirring is flowed out by grout outlet, to provide the ratio of mud that satisfies China's job specfication requirement to be about 0.4 cement mortar, make the usefulness of grouter, realized goal of the invention of the present invention to the enforcement grouting operation of bellows duct.
Embodiment 2: with reference to accompanying drawing.Present embodiment can have been realized the goal of the invention that the present invention is better electing the angle between stirring vane and the horizontal plane as 30 ° on the basis of embodiment 1.
Claims (3)
1. cement mixer, it comprises that mainly mixing drum is provided with motor, grout outlet, motor connects the vertical pivot in the mixing drum, it is one group stirring vane that vertical pivot is provided with at least 3, it is characterized in that: its axis direction of vertical pivot upper edge, relative one group of stirring vane are provided with another group stirring vane.
2. a kind of cement mixer according to claim 1 is characterized in that: the angle between stirring vane and the horizontal plane is 20 °～40 °.
