Abstract
The utility model relates to a deep soil sampler, in particular to a soil sampler capable of sampling deep soil; the deep soil sampler comprises a base box, a hollow drill bit and a sampling pipe, wherein the base box is internally provided with a speed reducer; a power shaft of the speed reducer is connected with a pedal pressure rod; a power output shaft of the speed reducer is connected with a spiral drill rod in a toothing way; the sampling pipe is arranged in the spiral drill rod; and the top of the spiral drill rod is connected with the hollow drill bit. Based on the traditional soil sampler, the deep soil sampler utilizes screw and lever principles and adopts the separating design, thus not only meeting the demand of deep soil sampling, but also being labor-saving and efficient; and the pedal type deep soil sampler has the advantages of being simple in structure, convenient to assemble, simple and convenient to use and high in working efficiency, and has very important significance for researching soil resources.
Description
Technical field
The utility model 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 in deep soil, variation has occured nutrient structure 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 profound soil nutrient and moisture and change and become important aspect in agricultural production, but the deep layer soil sample obtain deficiency due to technology and equipment, seriously hindered the research of deep layer soil layer.At present, the earth boring auger that China researcher uses is about 1m, the soil sample of layer 1m left and right of can only fetching earth, and in the arid area due to reasons such as soil compactions, 40cm is following is 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 during due to soil sample, technical key point can not destroy the sampling sample at that time, and use lower pestle as power fully, efficiency is low, gets the average approximately 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 is no standardized length, so also not portable when transporting.In production and scientific research, an urgent demand uses new equipment and method that deep soil is taken a sample.Making up 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 utility model 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 utility model 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 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 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 is all 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, based 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.

Embodiment
A kind of deep soil soil sample barrel, comprise pedestal case 1, hollow boring bit 6, stopple coupon 5, be provided with one speed reducer 2 in pedestal case 1, the line shaft of speed reduction unit 2 is connected with a foot pressure bar 3, the power output shaft of described speed reduction unit 2 and spiral drill pipe 4 toe joints, described stopple coupon 5 is arranged on spiral drill pipe inside, and the top of spiral drill pipe 4 connects hollow boring bit 6.
during use, pedestal case 1 is fixed on the ground, hollow boring bit 6 and stopple coupon 5 and a joint spiral drill pipe 4 are assembled together in rear insertion pedestal case 1, power output shaft toe joint with speed reduction unit 2, by foot pressure bar 3, drive speed reduction unit 2 work, make spiral drill pipe 4 slowly pierce in soil, when spiral drill pipe 4 will soon all enter pedestal case 1, another root spiral drill pipe 4 is connected and fixed with it, the length of every spiral drill pipe 4 is all 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 foot pressure bar 3, spiral drill pipe 4 drives stopple coupon 5 and hollow boring bit 6 just can be with the intact taking-up of deep layer soil sample of getting.
