This invention relates to the field of wheel hub dynamic balancing testing technology and discloses an integrated wheel hub dynamic balancing testing device, including a dynamic balancing machine body. During testing, the operator places the wheel hub inside the wheel hub limiting block, then drives the wheel hub upward via a hydraulic lifting rod, aligning the center hole of the wheel hub with the rotating shaft. A servo motor is then activated, driving a lead screw to rotate, which in turn moves a slider, which in turn moves the wheel hub, allowing it to be fitted onto the rotating shaft. While the wheel hub is on the shaft, a clamping sleeve is threaded onto the shaft and tightened, thus securing the wheel hub. Finally, the drive motor drives the rotating shaft to rotate, thereby testing the wheel hub. This structure saves time and labor, reduces labor consumption, improves testing efficiency, and enhances the practicality of the integrated wheel hub dynamic balancing testing device.

This invention discloses a floating object protection mechanism for a photoelectric sand measuring instrument, including a fixed base. A first fixed block is movably installed below the fixed base, and the sand measuring instrument body is installed on the side of the first fixed block away from the fixed base. Second fixed blocks are movably installed at both ends of the first fixed block. In this invention, by setting a rotating rod and movable rods, when the sand measuring instrument body is in use and other floating objects such as aquatic plants affect the test results, a second rotating motor drives the rotating rod to rotate at a preset angle. Subsequently, the two adjacent movable rods on the rotating rod move closer to each other, clamping the floating object. After the movable rods clamp the floating object, the extension of the electric extension rod and the rotation of the rotating rod can clamp the floating object and move it away from the sand measuring instrument body. Through this operation, aquatic plants and other floating objects around the sand measuring instrument body can be cleared.
