Description

Technical Field

[0001] The utility model relates to the field of mixing equipment for building construction, in particular to a mixer for construction engineering. Background Art

[0002] In the process of interior decoration, the walls need to be treated. Putty powder is usually stirred into a paste and applied to the wall to serve as the base treatment of the wall to prepare for subsequent painting. The uniformity of the putty powder mixing has a direct impact on the subsequent painting effect. In actual work, workers usually use a stirrer to reach into the mixing drum to stir the putty powder. During the stirring process, the worker holds the stirrer and moves it horizontally, and also needs to move the stirrer in the vertical direction to form a three-dimensional stirring of the putty powder.

[0003] With respect to the above-mentioned related technologies, the inventors found that workers move the stirrer up and down and horizontally for a long time. Since the stirrer has a certain weight and the putty powder has a certain viscosity during the stirring process, the workers need to use a lot of force to move the stirrer upward while stirring, which increases the labor intensity. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a stirrer for construction projects, which drives the stirrer body to move in the vertical direction through the lifting rod assembly, and shakes the stirrer body so that the stirring rod can stir the putty powder in the mixing drum in a three-dimensional manner, thereby enhancing the stirring effect and reducing the labor intensity of workers.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a mixer for construction projects, including: a mixing drum, a mixer body and a mixing rod connected to the mixer body, the upper end outer circle of the mixing rod is connected to a hemispherical shell, the opening of the mixing drum is detachably installed with a polygonal frame assembly, the two symmetrical sides of the polygonal frame assembly are respectively connected to a lifting rod assembly, a movable plate is connected between the tops of the lifting rod assemblies, a circular hole is provided in the center of the movable plate, a conical tube body is connected in the circular hole, and the inner cavity of the conical tube body is provided with the hemispherical shell.

[0006] By adopting the above technical solution, when in use, putty powder and related ingredients are put into the inner cavity of the mixing drum, the polygonal frame assembly is installed at the opening of the mixing drum, the stirring rod on the stirrer body is extended into the inner cavity of the mixing drum, and the lifting rod assembly is operated to drive the stirrer body to move in the vertical direction. Since the hemispherical shell on the stirring rod can slide arbitrarily in the inner cavity of the conical tube body, it is convenient for workers to shake the stirrer body to drive the stirring rod to stir the putty powder in three dimensions, thereby enhancing the stirring effect. That is, when the stirrer body moves upward, the worker does not need to bear the gravity of the stirrer body and the resistance of the putty powder to the upward movement of the stirring rod, thereby reducing the labor intensity of the worker.

[0007] In a preferred example, the present invention can be further configured as follows: the polygonal frame assembly includes a hexagonal frame body, two symmetrical sides of the hexagonal frame body are respectively connected to the lifting rod assembly, and the other four sides are respectively connected to locking rods, the locking rods include an L-shaped plate and a butterfly bolt spirally penetrated through the L-shaped plate, the L-shaped plate is connected to the side of the hexagonal frame body, and the end of the butterfly bolt is in close contact with the mixing drum.

[0008] By adopting the above technical solution, the hexagonal frame is placed on the top of the mixing drum, and the butterfly bolt is rotated so that its end is in close contact with the outer surface of the mixing drum, so that the hexagonal frame is indirectly fixed to the mixing drum, which is convenient for disassembly and installation, that is, the lifting rod assembly is indirectly fixed to the mixing drum.

[0009] In a preferred example, the present invention can be further configured as follows: the lifting rod assembly includes a mounting plate and an electric push rod fixed on the mounting plate, the protruding end of the electric push rod is connected to the movable plate, guide rods are respectively provided on both sides of the electric push rod, the guide rods include a guide sleeve and a guide rod body passing through the inner cavity thereof, the upper end of the guide rod body is connected to the movable plate, and the guide sleeve is embedded in the mounting plate.

[0010] By adopting the above technical solution, the telescopic rod of the electric push rod extends and contracts, thereby driving the movable plate to move in the vertical direction, and the movable plate drives the agitator body to move in the vertical direction. By using the guide rod, the stability of the movable plate during movement is enhanced.

[0011] In a preferred example, the present invention can be further configured as follows: the stirring rod member includes a rotating rod body, a connecting tube and a fixed rod, the upper end of the rotating rod body is connected to the stirrer body, the lower end of the rotating rod body is fixedly connected to the connecting tube, the fixed rod and the inner hole of the connecting tube are threadedly connected, and the spiral direction of the threaded connection between the fixed rod and the inner hole of the connecting tube is opposite to the direction in which the stirring body drives the rotating rod body to rotate, the lower end of the fixed rod is concentrically connected to a circular plate, and the upper plane annular array of the circular plate is connected to a plurality of strip-shaped stirring plates.

[0012] By adopting the above technical solution, since the spiral direction of the threaded connection between the fixed rod and the inner hole of the connecting pipe is opposite to the direction in which the rotating rod body is driven by the agitator body to rotate, the fixed rod is prevented from detaching from the connecting pipe during rotation, and the strip-shaped stirring plates on the circular plate stir the putty powder during rotation.

[0013] In a preferred example, the present invention can be further configured as follows: the stirring rod also includes a hexagonal column, the hexagonal column is provided with a through hole, and the fixing rod is passed through the through hole and fixedly connected to the through hole.

[0014] By adopting the above technical solution, the hexagonal column is connected to the fixing rod through the through-hole set, which makes it easy to use the wrench sleeve to remove or install the fixing rod on the hexagonal column, thereby improving the convenience of operation.

[0015] In a preferred example, the present invention can be further configured as follows: a U-shaped handle is connected to the top of the blender body, and rod-shaped handles are respectively connected to both sides of the blender body.

[0016] By adopting the above technical solution, workers can push and pull the U-shaped handle to drive the mixer body to shake, so that the stirring rod can stir the putty powder in the mixing drum in a three-dimensional manner. When the workers hold the rod-shaped handles on both sides of the mixer body with both hands, it is convenient to manually operate the stirring rod on the mixer body to stir the putty powder in the mixing drum in a three-dimensional manner, making the operation more convenient.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] Operating the lifting rod assembly drives the agitator body to move in the vertical direction. Since the hemispherical shell on the stirring rod can slide freely in the inner cavity of the conical tube body, it is convenient for workers to shake the agitator body to drive the stirring rod to stir the putty powder in three dimensions, thereby enhancing the stirring effect. That is, when the agitator body moves upward, the worker does not need to bear the gravity of the agitator body and the resistance of the putty powder to the upward movement of the stirring rod, thereby reducing the labor intensity of the worker.
