Description

Soil sampling device

Technical Field

The utility model relates to the field of soil sampling, in particular to a soil sampling device.

Background

In fertilizing crops, in the prior art, a drilling machine is generally used for drilling holes, the drilling machine comprises an auger, the auger rotates to take out soil and complete the drilling holes, then fertilizer is put into the holes, and then the excavated soil is backfilled into the holes, so that the fertilization is completed. However, when the applied fertilizer is a slow release fertilizer, the slow release fertilizer needs to be slowly released within a quite long time after being applied, so that the requirements on the geometric shape and the compactness of backfilled soil are met, the soil taken out after drilling by using the auger is loose, the compactness of the soil after backfilling the holes is poor, surface water and the like are excessively quickly soaked in the slow release fertilizer in the holes, the volatilization release speed of the slow release fertilizer is high, the slow release fertilizer is excessively quickly released, and the slow release effect is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a soil sampling device which can naturally form a backfill soil core column in the drilling process and has higher density of the soil core column.

In order to achieve the above object, the present invention provides a soil sampling device, comprising: the soil taking device comprises a soil taking head and a soil storing barrel, wherein a twisted piece is arranged on the inner wall of the soil taking head; deposit a soil section of thick bamboo and include two arc pipes, the inner wall of two arc pipes all is equipped with the extrusion piece, deposits a soil section of thick bamboo and fetches earth the head and can dismantle to be connected and two arc pipes pass through the concatenation of fetching earth the head.
