[0003] The technical problem solved by the utility model is that the stirring blades of the paint mixing equipment can only rotate on the same horizontal plane, and the paints of different depths cannot be efficiently mixed.
[0004] In order to solve the above-mentioned technical problems, the utility model provides the following technical solutions: a paint mixing device for construction, comprising a shell body provided with a feed port, a rotating shaft arranged in the shell body and protruding upward, and blades arranged on the rotating shaft, the shell body is provided with a driving unit for driving the rotating shaft to rotate, the blades arranged on the rotating shaft include upper blades and lower blades, the upper blades and the lower blades are fixed on the rotating shaft, the upper blades rotating with the rotating shaft can drive the paint in the upper space of the shell body to move downward, and the lower blades rotating with the rotating shaft can drive the paint in the lower space of the shell body to move upward.
[0005] According to the above technical solution, the rotating shaft rotates to drive the upper blade and the lower blade to rotate. Since the upper blade and the lower blade are inclined in opposite directions, the upper blade drives the paint in the upper space of the shell to move downward, and the lower blade drives the paint in the lower space of the shell to move upward. The paint collides at the center of the inner space of the shell. In this way, the paint is not only stirred by the upper blade and the lower blade in the shell, but also the upper paint and the lower paint in the shell collide, which is conducive to the full mixing of the paint.
[0006] A movable blade is pivotally connected to the rotating shaft, and the movable blade is located between the upper blade and the lower blade. Driven by the upper blade and the lower blade, the paint in the upper space of the shell body collides with the paint in the lower space at the center of the shell body. If the paint pressure from the upper space is greater than the paint pressure in the lower space, the movable blade rotates forward. If the paint pressure from the lower space is greater than the paint pressure in the upper space, the movable blade rotates reversely. The rotation of the movable blade, whether forward or reverse, can stir and mix the paint.
[0007] A fixed blade is arranged in the middle of the inner wall of the shell, and the fixed blade is located outside the movable blade.

The fixed blade cooperates with the movable blade to stir the paint, which is conducive to the full stirring of the paint.
[0008] An annular groove is provided in the middle of the inner side wall of the shell, and the fixed blade is arranged in the annular groove. The annular groove has a gathering effect on the paint, and the gathered paint passes through the fixed blade, which is conducive to the full stirring of the paint.
[0009] A discharge port is provided on the side wall of the shell, and the discharge port is at the same height as the fixed blade. Specifically, the discharge port is provided in an annular groove. The paint is stirred and driven by the upper blade and the lower blade, and reaches the movable blade. The movable blade drives the paint to move toward the annular groove, and after being stirred by the fixed blade, it flows out of the shell through the discharge port. Compared with the discharge port provided at the bottom of the shell, it is more appropriate for the discharge port of the utility model to be provided in the middle of the shell. As an improvement, a cleaning port is further provided at the bottom of the shell. When cleaning the paint in the shell, the residual paint inside the shell flows out through the cleaning port.
[0010] The driving unit comprises a motor, a main transmission wheel arranged on the motor shaft, a slave transmission wheel arranged on the rotating shaft, and a transmission belt connecting the main transmission wheel and the slave transmission wheel.
[0011] The top of the shell is provided with a top pivot structure, the bottom of the shell is provided with a bottom pivot structure, the top of the rotating shaft cooperates with the top pivot structure, and the bottom of the rotating shaft cooperates with the bottom pivot structure. The top of the shell is provided with a top shaft hole, and the bottom of the shell is provided with a bottom shaft hole. The top pivot structure includes a top bearing seat and a top bearing matched in the top bearing seat. The top of the rotating shaft passes through the top shaft hole upward, passes through the top bearing seat, and cooperates with the top bearing. A top sealing ring is provided between the rotating shaft and the top shaft hole, and a top sealing ring is provided between the rotating shaft and the top bearing seat.
