Summary: | The utility model relates to a device for manually taking soil samples on a shallow layer for geological prospecting. The device comprises a soil sample taking sleeve and further comprises a support used for installation of the soil sample taking sleeve. The support comprises a base plate and a vertical plate. A holding sleeve is spirally arranged on the outer wall of the soil sample taking sleeve. A holding ring portion is arranged at the lower end of the holding sleeve. A pressing rod is spirally arranged on the support. A pressing block is fixedly connected to the lower end of the pressing rod. The pressing block is arranged at the upper end of the soil sample taking sleeve. The device is simple in structure, reasonable in design and high in working reliability; by the adoption of the structure that the holding sleeve is used for locally sealing a soil sample, the soil sample is effectively prevented from being disengaged from the soil sample taking sleeve, and the soil sample taking efficiency is improved; the pressing rod is arranged on the soil sample taking sleeve, so that pressure is conveniently applied to the soil sample taking sleeve for soil sample taking, and operation is easy and convenient; the holding sleeve and the soil sample taking sleeve are of a spiral structure, and therefore holding operation is facilitated. |
