Problems solved by technology

[0003] In the process of collecting deep soil samples in the past, the collection method of destructive excavation was often used. For example, if the researcher plans to collect soil samples at a depth of 1-1.5m, he can only dig a soil pit with a depth of 1-1.5m at the soil collection point. Samples are then

Abstract

The invention discloses equipment for sampling different layers of a soil profile, which comprises a knocking soil drilling pipe. The side wall of the knocking soil drilling pipe is provided with a plurality of connecting holes, each connecting hole is in threaded connection with a sealing plug, the upper end of the knocking soil drilling pipe is detachably connected with an extrusion sleeve, and the extrusion sleeve is internally in threaded connection with a threaded sliding block. A first connecting rod and a second connecting rod are arranged at the upper end and the lower end of the threaded sliding block correspondingly. A pressing disc is connected to the lower end of the second connecting rod. The equipment also comprises a connecting shaft. A sliding cavity is formed inwards from one end of the connecting shaft, a piston is connected into the sliding cavity in a sliding mode, a penetrating hole is formed inwards in the other end of the connecting shaft, the other end of the connecting shaft is cut inwards to form a limiting sliding groove, and the limiting sliding groove comprises a vertical sliding groove body and a steering sliding groove body and is connected with a blocking piece in a sliding mode. The piston is connected with the blocking piece through a penetrating shaft, and the other end of the connecting shaft is connected with a cutting ring. The soil sampling method disclosed by the invention is simple, time-saving and labor-saving, has less damage to soil, and is suitable for soil sampling of sand land, wet land and the like.
