Foundation compaction degree detection device

The utility model provides a foundation compaction degree detection device which comprises a supporting frame, a movable wheel is installed at the bottom of the supporting frame, a pushing mechanism is fixedly installed in the middle of the supporting frame, a measuring needle is installed on the surface of the pushing mechanism, and through the arranged pushing mechanism, a stepping motor is controlled to rotate to drive a lead screw fixedly installed at the output end to rotate along with the lead screw. The screw rod rotates to drive the lifting block in threaded connection with the surface to rotate along with the screw rod, and the limiting blocks connected with the two sides of the lifting block slide on the surface of the limiting rod, so that the lifting block ascends and descends along the screw rod when the screw rod rotates, and the lifting block ascends and descends to drive the supporting seat and the measuring needle mounted on the surface to ascend and descend together; the measuring needle is
