Abstract

The present invention relates to a soil sampler for soil sampling, and in particular relates to a soil sampler capable of sampling deep soil. The soil sampler comprises a base box, a hollow drill bit, and a sampling tube; wherein a reducer is arranged inside the base box, the power shaft of the reducer is connected to a pedal pressure lever, the power output shaft of the reducer is in toothed connection with a spiral drill, the sampling tube is disposed inside the spiral drill, and the top of the spiral drill is in connection with the hollow drill bit. According to the present invention, based on the traditional soil sampler, by using screw and lever principles and separate design, the soil sampler both meets the needs of deep soil sampling, and is labor-saving and high efficient; and the pedal type deep soil sample is advantageous by being simple in structure, easy to assembly, convenient to use, and efficient in operation, having very important significance to the study of soil resource.

Description

A kind of deep soil soil sample barrel

Technical field

The present invention relates to a kind of soil sample barrel for soil sampling, especially a kind of soil sample barrel of taking deep soil.

Background technology

Agricultural soil is that agricultural production obtains one of high yield, high-quality, efficient resource, soil moisture, nutrient variable effect crop yield.With being widely used of chemical fertilizer, make the upper soll layer nutrient loss serious in recent years, nitrogen makes with oozing that variation has occured nutrient structure in the deep soil on the ground under water.Study simultaneously deep soil moisture content and Changing Pattern thereof, can effectively utilize the moisture characteristics of soil own, carry out the drought-resistant cultivating technical research, for ensureing that crop yield provides foundation.

Study in the profound soil nutrient and moisture and change and become important aspect in the agricultural production, but the obtaining because the deficiency of technology and equipment has seriously hindered the research of deep layer soil layer of deep layer soil sample.At present, the earth boring auger that China researcher uses is about 1m, the soil sample about layer 1m of can only fetching earth, and in the arid area owing to reasons such as soil compactions, 40cm is following to be difficult to lower boring, and the soil sample work efficiency is seriously reduced.Expend simultaneously a large amount of human and material resources.Use for a long time, in a large number, blindly traditional sampler, expended a large amount of funds and labour, make the research work emphasis not in the laboratory, and waste to the collection of field soil soil sample in a large number.

What the collection of profound soil sample was used traditionally is " Luoyang Spade ", but technical key point can not destroy the sampling sample at that time during owing to soil sample, and use lower pestle as power fully, efficiency is low, gets the average about 1h consuming time of the dark soil layer of 3m in the nonirrigated farmland according to the field statistics.And the soil sample length of taking out is difficult to control, because of in there not being standardized length, so also not portable when transporting.An urgent demand uses new equipment and method that deep soil is taken a sample in production and the scientific research.Remedying the deficiency of traditional soil sample barrel in the research of agricultural production and ecological environment of soil, is the research of deep soil nutrient and moisture.

Summary of the invention

The present invention ground purpose is to provide a kind of deep soil soil sample barrel of simple in structure, easy to assembly, easy to use, efficient work.

The invention discloses a kind of deep soil soil sample barrel, comprise the pedestal case, hollow boring bit, stopple coupon, it is characterized in that: be provided with one speed reducer in the pedestal case, the line shaft of speed reduction unit is connected with a foot pressure bar, the power output shaft of described speed reduction unit and spiral drill pipe toe joint, described stopple coupon is arranged on spiral drill pipe inside, and the top of spiral drill pipe connects hollow boring bit.

During use, the pedestal case is fixed on the ground, hollow boring bit and stopple coupon and a joint spiral drill pipe are assembled together in the rear insertion pedestal case, power output shaft toe joint with speed reduction unit, by the foot pressure bar, the work of driving speed reduction unit, make spiral drill pipe slowly pierce in the soil, when spiral drill pipe will soon all enter the pedestal case, another root spiral drill pipe is connected and fixed with it, the length of every spiral drill pipe all is the standard size of fixing, how pierce like this ground deeply just is easy to measure, get into need the degree of depth after, only need oppositely pedal the foot pressure bar, spiral drill pipe drives stopple coupon and hollow boring bit just can be with the intact taking-up of deep layer soil sample of getting.

Therefore, on traditional soil soil sample barrel basis, utilize spiral and lever principle, use separation design, demand, but also the Labor-saving high-efficiency of deep soil sampling had not only been reached, foot-operated deep soil sampler structure is simple, easy to assembly, easy to use, the advantage of efficient work, and research soil resource is had very important significance.
