Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 and 2, the present invention provides a soil sampler, which comprises a driving rod 10, a drill bit 20 and a sampling sleeve 30, wherein the drill bit 20 is driven into soil through the driving rod 10, the sampling sleeve 30 is sleeved on the driving rod 10, and the soil is sampled layer by layer.

Specifically, one end of the driving rod 10 is connected with the drill bit 20, and the diameter of the driving rod 10 is smaller than that of the connected end of the drill bit 20, so that the drill bit 20 can be made to perforate in the soil and to drill under the soil by rotating the driving rod 10. The sampling sleeve 30 comprises a sleeve 31, an insertion rod 32 and a plurality of sampling tubes 33, wherein the sleeve 31 is axially arranged along the driving rod 10 and can be sleeved on the driving rod 10 from one end of the driving rod 10 far away from the drill bit 20, the sleeve 31 is axially provided with a plurality of arrangement holes 311 which are radially opened, and the number of the sampling tubes 33 is the same as that of the arrangement holes 311 and the sampling tubes 33 are inserted into the arrangement holes 311 one by one.
