Convenient and labor-saving soil drill

Abstract

The invention discloses a convenient and labor-saving soil drill. The convenient and labor-saving soil drill comprises two stand columns, wherein the tops of the two stand columns are fixedly connected with a top plate; a soil drilling mechanism is arranged at the bottom of the top plate; the top end of the soil drilling mechanism extends to the top of the top plate; the soil drilling mechanism comprises a supporting ring; the supporting ring is located at the bottom of the top plate; the supporting ring is located at the inner sides of the two stand columns; a thread rod is embedded into thesupporting ring; the thread rod is in thread connection with the supporting ring; and the top end of the thread rod extends to the top of the top plate. According to the convenient and labor-saving soil drill disclosed by the invention, the soil drilling mechanism is arranged; in actual utilization, a user only needs to rotate a handle by hands to drive a rotary table to rotate, so that a soil sampling pipe can rotate downward and is inserted into soil; downward pressure is provided for the soil sampling pipe all the time; the handle is reversed and the soil sampling pipe is pulled out, so that a soil sample in the soil sampling pipe can be taken out and soil sampling work is finished; the convenient and labor-saving soil drill is relatively convenient to use; and the stretching length ofthe handle can be rapidly adjusted and the rotary table is rotated so that the convenient and labor-saving soil drill is relatively light and labor-saving and has relatively strong practicability.

Description

technical field [0001] The invention relates to the technical field of earth drills, in particular to a convenient and labor-saving earth drill. Background technique [0002] Soil sampling refers to the method of collecting soil samples, including the arrangement of samples and sampling techniques. The section soil samples should be taken after the section observation and record 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, it is necessary to take the plot as a unit, sample at multiple points, and then mix them into a mixed sample, so as to better represent the soil properties of the sampling area. Sampling methods generally have the following types. Diagonal sampling method: suitable for sewage irrigation plots, sampling at the central point of each diagonal line. Plum-shaped sampling method: s...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a convenient and labor-saving earth drill. It has been solved that the earth drill in the prior art is laborious to drill when rotating and sampling, and requires the user to bend over to work continuously, and the work intensity is relatively high. The problem of low soil efficiency
