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 collected on the soil profile of the pit wall, a method that is time-consuming, laborious, and severely soil-damaging
In addition, many soils with poor plasticity, such as sandy land, wetland and other ecosystems, are difficult to excavate into shaped soil profiles, which brings a lot of inconvenience to research

Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0031] In describing the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer" etc. indicate an orientation or position The relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, therefore It should not be construed as a limitation of the present invention.
[0032] Furthermore, the terms "horizontal", "vertical" and the like do not imply that a component is absolutely level or overhanging, but may be slightly inclined. For example, "horizontal" only means that its direction is more horizontal th...

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.
Description
technical field [0001] The invention relates to the technical field of soil sampling equipment, in particular to a device for sampling different layers of soil profiles. Background technique [0002] Soil has a very important research status in many disciplines such as soil science, environmental science, geology, geotechnical science, and ecology. It is very important to collect scientific soil samples according to the purpose of the experiment. During the collection of soil samples, researchers try to keep the soil as undisturbed as possible, and hope to learn more about the deep profile of the soil. Many soil studies include the study of deep soil samples. In the collection of deep soil samples, how to reduce the disturbance of soil samples and reduce the amount of earth excavation as much as possible to obtain deep soil samples has been a problem that has plagued researchers for a long time. . [0003] In the process of collecting deep soil samples in the past, the col...
