Description

Novel soil sampling rig auger bit

Technical Field

The utility model belongs to rig drill bit sampling machine field particularly, relates to a novel soil sampling rig auger bit.

Background

Soil sampling refers to a method for collecting soil samples, and comprises sampling arrangement and sampling technology. The sampling of the soil sample in the cross section is performed after the cross section observation is completed. Before sampling, the section should be trimmed and cleaned, the superficial layer of the floating soil is cut off, and then the sample is taken from the central typical part layer by layer from top to bottom according to the layers.

There are many types of soil samplers. And (3) collecting a surface soil sample of the farm land or the wasteland, wherein a small iron shovel can be used. The cutting ring can be used for researching general physical properties of soil, such as soil volume weight, porosity, water retention property and the like. The cutting ring is a cylinder with openings at two ends, the lower opening is provided with a blade, and the height and the diameter of the cylinder are both about 5 cm. The most common sampling tool is an earth auger. Earth boring tools are classified into two types, manual operations and mechanical operations. The manually operated soil drill has a plurality of types, a short handle soil drill for collecting shallow soil samples and a screw head soil drill for observing the profile characteristics in soil layers of about 1 m are provided, the screw head soil drill is labor-saving in soil feeding, is particularly suitable for observing underground water level changes, but is small in soil sample collecting amount. When a soil sample for chemical analysis or physical analysis of undisturbed soil is collected, an open-type soil drill is used. An undisturbed soil sample which does not damage the structure or shape of the soil is collected and is drilled by a sleeve type soil drill (figure 2).
