Screw rod lifting cutting ring soil sampling device

Abstract

The utility model relates to the technical field of engineering construction inspection and test equipment, in particular to a screw rod lifting cutting ring soil sampling device. Comprising a cutting ring cover used for installing a cutting ring, the lower end of the cutting ring cover is provided with internal threads used for installing the cutting ring, the upper end of the cutting ring cover is fixedly connected with a screw rod, the screw rod is inserted in a worm gear case in a penetrating mode, the upper end of the worm gear case is fixedly provided with an impact vibrator, and a worm gear is installed in an inner cavity of the worm gear case. The worm gear is meshed with a worm, the two ends of the worm are rotatably inserted into the side wall of the worm gear case, and one end of the worm is in transmission connection with a motor. According to the soil sampling device, automatic operation of soil sampling operation is achieved, the cutting ring is placed, taken out and knocked by an automatic machine, the working efficiency is improved while the labor intensity is relieved, the influence of human factors on detection data can be effectively reduced, and the soil sampling device is particularly suitable for large-area sampling operation.
