Detailed Description

Referring to fig. 1-4, the present invention provides a technical solution:

a soil sampling device for national soil resource supervision and management comprises a holding casing 1, wherein four limiting rods 101 are fixedly arranged at the front part of the holding casing 1, push plates 102 are fixedly arranged on the bottom surfaces among the four limiting rods 101, the push plates 102 are convenient for pushing out samples in sampling tubes 4 when the sampling tubes 4 are retracted, a power control module is arranged at the rear part of the holding casing 1, a motor 2 is embedded in the left wall of the holding casing 1, a gear 201 is fixedly arranged at the output end of the motor 2, a lifting rod 3 is arranged at the middle part of the holding casing 1, a graduated scale is arranged on the front wall of the lifting rod 3, the graduated scale is convenient for visually knowing the downward extension height of the sampling tubes 4, a gear rail groove 301 is formed in the rear wall of the lifting rod 3, a through groove 302 is formed in the left wall of the lifting rod 3, the through groove 302 is convenient for movement of a limiting pressing plate 304, a sliding rod 303 is inserted in the lower part of the lifting rod 3, the top surface of the sliding rod 303 is fixedly provided with the limiting pressing plate 304, an adjusting screw 305 is in threaded fit with the right end of the limiting pressing plate 304, a positioning rod 306 is inserted in the left wall of the limiting pressing plate 304, the bottom surface of the lifting rod 3 is fixedly provided with a sampling cylinder 4, the bottom surface of the sampling cylinder 4 is hinged with four conical plates 5, the conical plates 5 are convenient for the sampling cylinder 4 to be rapidly inserted into soil, and the inner wall of each conical plate 5 is hinged with a push-pull rod 501.

Specifically, the gear 201 is in meshing transmission with the gear rail groove 301, so that the sampling cylinder 4 is driven to move downwards to enter soil for sampling.

Further, the adjusting screw 305 is rotatably engaged with the grip sleeve 1, so that the adjusting screw 305 can rotate conveniently, and the limiting pressing plate 304 is driven to move downwards to push the push-pull rod 501 to open the conical plate 5.
