Abstract

The utility model discloses a multifunctional soil sampler which comprises a hollow drill rod; the upper end of the drill rod is provided with a first handle; the bottom end of the drill rod is movably connected with a drill bit; the hollow part of the drill rod is internally provided with a push rod; the upper end of the push rod extends outside the upper end of the drill rod; the upper end of the push rod is provided with a second handle; the bottom end of the push rod is provided with a barrier piece; and the barrier piece is arranged in the soil sampling space of the drill bit. According to the multifunctional soil sampler, different drill bits are adopted to be movably connected with the drill rod, so that the different soil sampling demands can be met, quantification can be realized, and the soil of all points can be consistent and uniform up and down; and therefore, the multifunctional soil sampler provides a possible condition for obtaining reliable and accurate data for knowing the physical and chemical properties of soil.

Description

A kind of multifunction soil sampling thief

Technical field:

The utility model belongs to soil investigation, investigation field, is specifically related to a kind of sampling apparatus of carrying out collecting soil sample-multifunction soil sampling thief.

Background technology:

Soil is one deck important in earths layers, is the important environment that the mankind and other biology are depended on for existence, and each Plants, animal rely on the soil growth, and in so-called all things on earth soil, life is namely this reason.Carrying out the investigation of soil, the collection that research be unable to do without pedotheque, and how accomplish both fast to collect accurately representational pedotheque in the open air soil sampling process, is namely the problem that soil sampler need to solve.

Traditional collecting soil sample instrument, majority was to gather materials on the spot in the past, adopted apparatus hoe or the spade of peasant's farming, also there is the military folding spade of employing in the modern times.Because above instrument relates to artificial cutout in sampling process, be difficult to accomplish that the sample size of every bit collection is consistent, and same sampled point levels sampling quantity often also can be different, this has just caused the representational error of soil sample larger.But the pedotheque sampling thief of therefore researching and developing a kind of quantitative sampling is necessary.

Summary of the invention:

The purpose of this utility model is to provide a kind of energy accurate quantification, satisfies the multifunction soil sampling thief that soil sample gathers that carries out of multiple demand.

The utility model is achieved by the following technical programs:

Multifunction soil sampling thief of the present utility model, it is characterized in that, the drilling rod that comprises hollow, upper end at drilling rod is provided with the first in command, and the bottom of drilling rod is connected with drill bit, is provided with push rod in the hollow space of drilling rod, the upper end of drilling rod is stretched out in the upper end of push rod, the upper end of push rod is provided with the second in command, and the bottom of push rod is provided with the obstruction sheet, stops sheet and is located in the earth space of fetching earth of drill bit.

Described drill bit is preferably with drilling rod and is threaded, and is threaded to be convenient to change different drill bits, to satisfy different needs.

Its lower end mouth of pipe of described drill bit is preferably polished and is made its form with knife edge, can cut off the root system of plant in soil when being beneficial to sample and easily cut soil, facilitates the collection of pedotheque.

Described drill bit is preferably 3, comprise an external diameter be 5cm, highly for 20cm, tube thickness is that 3mm, stainless steel label are 304 core cutter, external diameter is 3cm, highly is 20cm, tube thickness is that 3mm, stainless steel label are 304 core cutter, and one long for 100cm, external diameter be that 2cm, tube thickness are that 3mm, stainless steel label are 304 section core cutter, the section core cutter, having width in a side of pipe is 0.5cm, highly is to facilitate the taking-up of collected specimens by the sampling opening of 95cm from bottom to up.Three kinds of core cutters satisfy different needs.

multifunction soil sampling thief of the present utility model is to use like this: according to the sampling request of different topsoils, select different core cutters, when sampling, hold the first in command on drilling rod, with the soil of drill bit to firmly sampling, then firmly toward pressing down, drill bit enters in soil, the earth space of fetching earth of drill bit is filled with sampling soil, obstruction sheet on push rod moves up under the promotion of soil, along with moving down of drilling rod, soil is full of the earth space of fetching earth of drill bit, due to the obstruction that stops sheet, soil can not enter the hollow space of drilling rod, sample complete, up draw the first in command, and then push away the second in command, sampling soil is released, and obtain pedotheque.

The utility model can satisfy different soil samples and gather demand, and accomplish quantification by adopting different drill bits and drilling rod to be flexibly connected, and guarantee that every bit soil amount is consistent, the up and down is impartial, thus for understanding soil physico-chemical property, obtain reliable and accurately data possible condition is provided.

Fig. 1 is the structural representation of multifunctional sampling instrument of the present utility model;

Wherein 1, drilling rod; 11, the first in command; 2, push rod; 21, the second in command; 22, stop sheet; 3, drill bit.

Embodiment:

Following examples are to further illustrate of the present utility model, rather than to restriction of the present utility model.

Embodiment 1:

As shown in Figure 1, multifunctional sampling instrument of the present utility model, the drilling rod 1 and the drill bit 3 that comprise hollow, the long 50cm of drilling rod, caliber is that 2cm, thickness of pipe are that 2mm, label are 304 stainless-steel tube, be welded with 2 stainless steel handles that are arranged above and below in the upper end of drilling rod 1 as the first in command 11, being welded with a model in the bottom of drilling rod 1 is screw socket loose joint in the stainless steel of 1/2 cun.described drill bit 3 is 3, comprise that an external diameter is 5cm, be highly 20cm, tube thickness is 3mm, the stainless steel label is 304 core cutter, an external diameter is 3cm, be highly 20cm, tube thickness is 3mm, the stainless steel label is 304 core cutter, and one long be 100cm, external diameter is 2cm, tube thickness is 3mm, the stainless steel label is 304 section core cutter, the section core cutter, having width in a side of pipe is 0.5cm, be highly the sampling opening of 95cm from bottom to up, facilitate the taking-up of collected specimens, the lower end mouth of pipe of three kinds of drill bits is polished respectively and is made it have the form of the knife edge, can cut off the root system of plant in soil when being beneficial to sample and easily cut soil, facilitate the collection of pedotheque.Drill bit 3 is threaded with the interior screw socket loose joint of stainless steel of drilling rod 1 bottom, be provided with push rod 2 in the hollow space of drilling rod 1, it is that diameter is that 0.8cm, length are the stainless rod of 80cm, the upper end of drilling rod 1 is stretched out in the upper end of push rod 2, the upper end locking of push rod 2 has the stainless steel nut as the second in command 21, the bottom of push rod is welded with stainless steel substrates as stopping sheet 22, stops sheet 22 and is located in the earth space of fetching earth of drill bit 3.
