Abstract

The utility model relates to processing mechanical technical field of building material, in particular to an air-adding concrete mixer. A mixing barrel is internally provided with a mixing mechanism in a group way which consists of a spiral mixing vane and a rotary shaft; the mixing vane is fixedly arranged on the lower end of the rotary shaft; the internal bottom end of the mixing barrel is provided with a taper cover body which can movably open and close a material outlet; the upper side of the taper cover body arranged around the mixing vane is provided with a hopper-shaped material inlet cylinder; an upper and lower ports of the material inlet cylinder are communicated with a cavity in the mixing barrel; by the incline surface function of the external edge of the taper cover body, the mixing vane is matched to lower push the mixing material, leading to the sunk mixing material shunting to four sides and flowing with upper turning; after that, the mixing material enters into the material inlet cylinder to sink with the rotation of the mixing vane again; the mixing is more uniform, and the utility model can effectively reduce the resistance acting on the mixing vane.

Description

The air entrained concrete mixer

Technical field:

The utility model relates to the processing equipment technical field of construction material, refers in particular to a kind of air entrained concrete mixer.

Background technology:

When producing air entrained concrete, the mixer that is used for spice is an imperative equipment.And existing air entrained concrete mixer, it mainly includes a cylindric spice bucket, behind the corresponding material of the interior injection of bucket, rotating shaft by the electrical motor driven mixing device, drive its inner paddle by rotating shaft and rotate, thereby stir the interior compound of bucket, make different mixing of materials even.Yet, presently used air entrained concrete mixer, the interior end of spice bucket is a concave arc shape, and paddle mainly is the compound turn that drives its outer peripheral edges when stirring, compound for the axis position generally all is the concave arc place sinkings at the past bucket end, not only the amplitude of turn is little, but also can produce the rotation that certain resistance hinders paddle, strengthens the load of rabbling mechanism.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, and a kind of materials flow resistance that effectively reduces is provided, the more uniform air entrained concrete mixer of spice.

For achieving the above object, the paddle of the utility model is a helical form, and be provided with a movable taper lid of opening and closing discharging opening in the interior bottom of spice bucket, the upside of taper lid, be positioned at and set up a funnel-form feeding cylinder around the paddle, the two-port up and down of feeding cylinder all with the spice bucket within the cavity connection.

Described taper lid is opened and is closed by an air cylinder driven, cylinder be arranged at the taper lid under, its piston rod bottom overhanging and that run through under the discharging opening behind the side flange with the taper lid is connected, and with material receiving tube that discharging opening is connected be the cross break setting; The following folding section in material receiving tube exit is provided with telescopic outer tube.

After adopting such structure, utilize the ramp effect of the external edge of conical lid, cooperate the power that pushes away compound under the paddle to make the compound of sinking do the shunting of four sides, and flowing of turning on having mixed with the compound of paddle outer peripheral edges, following the paddle rotation from the upper port suction of feeding cylinder again subsequently sinks, constantly circulation mixes more evenly, and reduces the suffered resistance of paddle effectively.

Accompanying drawing 1 is the utility model overall structure schematic diagram;

Accompanying drawing 2 is the side view of the utility model;

Accompanying drawing 3 is the utility model partial structurtes schematic diagrames;

Accompanying drawing 4 is the syndeton schematic diagram of the telescopic sleeve pipe of material receiving tube.

The specific embodiment:

See that shown in the accompanying drawing 1～4, the utility model includes spice bucket 1, group is established a rabbling mechanism 2 of being made up of helical form paddle 20 and rotating shaft 21 in the spice bucket 1, and paddle 20 is installed in the lower end of rotating shaft 21.The interior bottom of spice bucket 1 is provided with a movable taper lid 3 of opening and closing discharging opening 11, taper lid 3 is a ducted body, set up a funnel-form feeding cylinder 22 at the upside of taper lid 3, around being positioned at paddle 20, the two-port up and down of feeding cylinder 22 all with spice bucket 1 within the cavity connection.Taper lid 3 is driven by a cylinder 4 and opens and close, cylinder 4 be arranged at taper lid 3 under, cylinder 4 be arranged at taper lid 3 under, its piston rod 41 bottoms overhanging and that run through 11 times side flanges of discharging opening, 111 backs and taper lid 3 are connected, and the interior mesopore of 11 times side flanges 111 of discharging opening gives piston rod 41 guide-localizations simultaneously.The material receiving tube 12 of connecting discharging opening 11 is the cross break setting, and is arranged with telescopic outer tube 121 in the following folding section outer rim in material receiving tube 12 exits.

During use, corresponding mixing of materials is injected in the spice bucket 1, starter 5 subsequently, drive rotating shaft 21 rotations by it, and the paddle 20 that rotating shaft 21 drives on its inner rotates, thereby stir the compound in the spice bucket 1, and different materials is mixed mutually.Paddle 20 is shape in the shape of a spiral, cooperate the feeding cylinder 22 promotion feeding cylinders 22 interior mixed material turns of its outer peripheral edges to sink, do the shunting of four sides when dirty material contacts inclined plane around the taper lid 3, and flow out and upwards roll, with the mixing of materials of feeding cylinder 22 peripheries by feeding cylinder 22 lower port, enter stirring area from the upper port of feeding cylinder 22 again subsequently, go round and begin again, mix more evenly, and reduce the bounce of sinking material, reduce paddle 20 suffered resistances effectively, it is easier to stir.

During blowing, connect the source of the gas of cylinder 4, cylinder 4 pushing piston-rods 41 are pushed taper lid 3 from the bottom up open, move on the taper lid 3 and open the discharging opening 11 of spice bucket 1 lower end, realize blowing, and the valve of at this moment opening again on the material receiving tube 12 122 can be realized cast.And to be provided with telescopic outer tube 121 be in order to satisfy the requirement of different framed 6 height in the exit of material receiving tube 12, so that better cast.When closing discharging opening 11, cylinder 4 is done and is reclaimed action and can retract taper lid 3 by piston rod 41 and reset and cover discharging opening 11, and the interior mesopore of 11 times side flanges 111 of discharging opening gives piston rod 41 mobile guides location simultaneously.
