Mechanical rotating device for rock-soil layer dynamic penetration test probe rod

The utility model discloses a mechanical rotating device for a rock-soil layer dynamic penetration test probe rod, which comprises a plate body, a rotating mechanism is arranged at the top of the plate body, the rotating mechanism comprises a first motor, the first motor is arranged at the top of the plate body, and the output end of the first motor is fixedly connected with a speed reducer. According to the mechanical rotating device for the rock-soil layer dynamic penetration test feeler lever, when the feeler lever in the rotating mechanism moves downwards and stretches into soil, a first motor is connected with an external power source and drives a speed reducer to rotate, the speed reducer drives a round rod to rotate, and when the round rod rotates, through sliding connection of a sliding block and a sliding groove, the round rod is driven to rotate; the probe rods with different depths can be driven to rotate stably, the problem of mechanical rotation of the probe rods in the test process is solved, in
