Description

Convenient and labor-saving soil drill

Technical Field

The invention relates to the technical field of earth drills, in particular to a convenient and labor-saving earth drill.

Background

Soil sampling refers to a method for collecting soil samples, and comprises sampling arrangement and sampling technology. The sampling of the section soil should be performed after the section observation and recording are finished, and the sampling by using a metal instrument should be avoided if the content of the metal in the soil is to be analyzed. During field sampling, soil has heterogeneity of spatial distribution, so that the soil characteristics of a sampling area can be represented better by taking a plot as a unit, sampling at multiple points and mixing into a mixed sample. The following methods are generally used for sampling. Diagonal sampling method: is suitable for sewage irrigation plots and sampling at the central points of each equal division of the diagonal line. Quincunx sampling method: is suitable for plots with small area, flat terrain and uniform soil. A checkerboard sampling method: is suitable for plots with medium areas, flat terrain, basically complete terrain and less uniform soil. A snake sampling method: the method is suitable for the plots with small areas, uneven terrains and uneven soil, and more sampling points are required to be taken. The depth depends on the purpose of sampling, and is generally 0-20cm in the cultivated layer. 1-2kg of mixed sample is taken. If the amount is too large, the excess soil can be discarded by quartering. The collected soil sample is put into a cloth bag or a polyethylene plastic bag, and labels are attached to the inside and the outside of the bag to indicate the sampling number, the name, the sampling depth, the sampling place, the date and the collection person. Soil samples for chemical analysis (heavy metal removal analysis) may be sampled using an auger, used as soil samples for volumetric determination, and sampled using the ring cutter method.

Before sampling, a section is trimmed and cleaned, the most superficial layer of floating soil is cut off, then the soil is sampled from a central typical part layer by layer from top to bottom according to the layers, soil sampling work is often carried out by using a soil drill, the traditional soil drill is generally in a T shape, the structure is simple, the function is single, the use is not convenient, the labor is wasted, a user needs to work by bending continuously, the working strength is high, and the soil sampling efficiency is low.
