AI Technical Summary
The existing mixer blades are difficult to remove quickly, leading to pipe blockage and cleaning difficulties.
Multiple blades are installed inside the pipe. The elastic force of the first spring is used to keep the clamping block stable in the groove. The push rod pushes the clamping block out of the groove. The blades are stabilized and quickly replaced by the engagement of the protrusion and the rectangular groove. At the same time, the vibration of the ring and the connecting plate is used to clean the residual mud inside the pipe.
This method enables the blades to be securely and quickly removed, reducing pipe blockage and improving cleaning efficiency.
