Description

A stirring device for construction engineering

technical field

The utility model relates to the technical field of construction equipment, in particular to a stirring device used for construction projects.

Background technique

In the field of construction engineering, the use of dry-mixed mortar is more and more extensive. Dry mixed mortar is usually called hydraulic cement mixed mortar, which refers to the physical mixing of dried and screened aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) in a certain proportion. It is a kind of granular or powdery material that is transported to the construction site in the form of bags or bulk, and can be used directly after mixing with water. The stirring paddles provided in the existing dry-mixed mortar stirring equipment are all arranged perpendicular to the stirring shaft, and the structure is relatively simple, so that it is difficult to achieve better uniformity in the three-dimensional coordinate direction of the stirring tank at the same time, and the stirring effect is poor.

Utility model content

The technical problem to be solved by the utility model is to provide a stirring device for construction engineering, which can uniformly stir dry-mixed mortar.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A stirring device for construction engineering, comprising a stirring barrel, a feeding port and a discharging port arranged on the stirring barrel, a stirring shaft arranged in the stirring barrel and extending out of the stirring barrel at both ends, and one end of the stirring shaft And the motor that drives it to rotate and the stirring paddle arranged on the stirring shaft are improved in that: the stirring paddle comprises a stirring blade, a strut that is fixedly connected between the stirring blade and the stirring shaft, and the stirring blade is in the shape of a flat plate, One end of the support rod is fixedly connected to one plate surface of the stirring blade, the other plate surface of the stirring blade is provided with a plurality of grooves, and the axis of the stirring blade and the stirring shaft has an included angle of 20° to 40°; The axes of the shafts are distributed at intervals, and there are at least three stirring paddles, and the adjacent three stirring paddles are distributed at an angle of 120° along the circumferential direction of the stirring shaft.

As a further improvement of the above technical solution:

The stirring paddles are equally spaced.

The stirring blade is in the shape of a rectangle, and the groove direction of the groove is the direction of the long side of the rectangle.

The two ends of the stirring shaft extending out of the stirring barrel are carried by the bearing seat.

A reducer for reducing transmission is arranged between the motor and the stirring shaft.

The output shaft of the reducer and the stirring shaft are coaxially driven through a coupling.

The bottom of the mixing bucket is also supported with feet.

The beneficial effects of the present utility model are:

The stirring blade of the utility model is in the shape of a flat plate with an included angle of 20° to 40° with the axis of the stirring shaft, and has a larger stirring surface, and the set angle is favorable for the flow of materials during stirring, and the stirring blades are along the circumference of the stirring shaft. It is evenly distributed at an angle of 120° between phases, which can further ensure that the three-dimensional coordinate direction of the mixing tank can achieve better uniformity at the same time, thereby ensuring that the dry-mixed mortar is evenly stirred.
