Description

Mortar mixer

Technical field

The utility model relates to a kind of being applicable in the building trade finished product dry-mixed mortar is carried out the on-the-spot device that stirs.

Background technology

Cause is to requirement on environmental protection, and building trade adopts the finished product dry-mixed mortar, but on-the-spot the stirring also brought technical barrier.Existing mortar mixer generally includes charging aperture, parts such as transportation section, stirring section and discharging opening, and transportation section and stirring section are positioned at shell, and charging aperture and discharging opening are opened the two ends at shell, have water inlet on the pairing shell of stirring section.Shaft is through the transportation section and stir section, and shaft is through motor-driven.Be welded with helical blade being positioned on the shaft of transportation section, be positioned at the shaft that stirs section and be provided with mixing arm, the set-up mode of mixing arm is: hole on shaft, the eyelet welding that the axle of mixing arm passes shaft connects the purpose that fixedly reaches anti-rotation and setting angle, such set-up mode, welding and boring can influence the intensity and the precision of shaft, and dismounting is inconvenient; And the stirring vane that is arranged on the mixing arm mostly is slab construction, just reaches the purpose of stirring by the difference of setting angle, and this setup can strengthen the drive motors load, material stirs inhomogeneous, mixing time is long, and speed is slow, can't accomplish continuous stirring.

The utility model content

For solving the problems of the technologies described above, the utility model proposes a kind of stirring, speed is fast, and can accomplish the mortar mixer of continuous stirring, the shaft that the utility model adopts, the installing/dismounting maintenance is more convenient.Mixing arm can make drive unit load reduce, and material separates to both sides from the centre of mixing arm in the high-speed stirred process, under the effect, material is stirred fast, thereby reach the purpose of continuous stirring in coaxial a plurality of mixing arms.

The utility model is achieved by the following technical solution:

A kind of mortar mixer, comprise and stir section, stir in the section and be penetrated with shaft, it is characterized in that: the cross section of described shaft is a hexagon, on the shaft that is positioned at described stirring section a plurality of agitating devices is installed, and described agitating device comprises the borehole jack with described shaft coupling, described borehole jack is fixedlyed connected with mixing arm, free end at described mixing arm is provided with stirring vane, and described stirring vane is the scraper plate of rhombus, and two scraper plates are installed in the free-ended left and right sides of mixing arm.

Described borehole jack and mixing arm are formed in one.

Mortar mixer also includes the transportation section, is with the helical blade with described shaft coupling outside being positioned at the shaft of described transportation section.

Described transportation section and stirring section are positioned at shell, have water inlet in stirring the pairing shell of section, and charging aperture and discharging opening are opened the two ends at shell.

One end of described shaft is connected with reduction box through the anti-rotation buckle, and described reduction box drives through drive unit.

Described drive unit is a motor.

Advantage of the present utility model shows:

1, because the cross section of the shaft that the utility model adopts is a hexagon, and on shaft, be with borehole jack with the shaft coupling, borehole jack is connected with the mixing arm that the rhombus scraper plate is installed, such technical scheme compared with prior art, the intensity of shaft is good, easy installation and removal, the hexagon borehole jack on the mixing arm directly is inserted on hexagonal shaft, and fit clearance is little, positioning accuracy is high.The design of the scraper plate of rhombus can make the load of drive unit reduce, and material separates to both sides from the centre of mixing arm in the high-speed stirred process, under the effect of adjacent a plurality of mixing arms, can make material be positive and negative eddy current shape rapid movement, and material stirs fast.The design of rhombus scraper plate has strengthened mixing arm shock resistance, anti abrasive performance, and the motion mode when material is stirred is different with general agitating device, has improved stirring efficiency, and material is mixed fast fully, thereby has realized the purpose of continuous stirring.

The set-up mode that 2 borehole jacks and mixing arm are formed in one compared with prior art, can be avoided boring and welding on shaft, thereby can not influence the intensity and the precision of shaft.
