Description

A 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 technique

Soil sampling refers to the method of collecting soil samples, including sampling layout and sampling techniques. The collection of cross-section soil samples should be carried out after the cross-section observation records are completed. If the metal content in the soil is to be analyzed, the use of metal utensils for sampling should be avoided. When sampling in the field, due to the heterogeneity of the spatial distribution of the soil itself, the plot should be taken as the unit, multiple points should be sampled, and then mixed into a mixed sample, so as to better represent the soil properties of the sampling area. There are generally the following sampling methods. Diagonal sampling method: suitable for sewage irrigation plots, sampling at the central point of each diagonal line. Plum-shaped sampling method: suitable for plots with small area, flat terrain and uniform soil. Checkerboard sampling method: suitable for plots with medium area, flat terrain, basically complete terrain and uneven soil. Snake-shaped sampling method: It is suitable for plots with smaller area and less flat terrain and less uniform soil, and more sampling points must be taken. The depth depends on the purpose of sampling, generally the ploughing layer is 0-20cm. Take a mixed sample of 1-2kg. If the quantity is too large, the excess soil can be discarded by quartering. Put the collected soil samples into cloth bags or polyethylene plastic bags, and labels should be attached both inside and outside, indicating the sampling number, name, sampling depth, sampling location, date, and collector. Soil samples used for chemical analysis (except heavy metal analysis) can be sampled with soil drills, and soil samples used for volume determination should be sampled by the ring knife method.

Before sampling, the section should be refurbished and cleaned, and the topmost layer of floating soil should be cut off, and then the samples should be taken from the central typical part layer by layer from top to bottom. Traditional soil drills are usually T-shaped, with simple structure but very single function. It is not very convenient to use, and it is also laborious, and requires the user to bend over to work constantly, which has high work intensity and low soil borrowing efficiency.

Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a convenient and labor-saving earth drill.
