Referring to fig. 1 and 2, the sampler for small and medium-sized soil animals of the present embodiment includes a drilling barrel 100, at least one fastener 200, and an extraction device 300. The drill cylinder 100 comprises a first half pipe 101 and a second half pipe 102, cutting edges 103 are arranged on two sides of the bottom end of the drill cylinder 100, and scale marks 104 are arranged on the outer wall of the drill cylinder 100 and are suitable for quick multipoint sampling of small and medium-sized soil animals. At least one fastener 200, first tube half 101 and second tube half 102 are fastened and secured by fastener 200. An extraction device 300, wherein the extraction device 300 is arranged at the top end of the drill barrel 100.
According to the sampler, the cutting edge 103 is arranged on at least one side of the bottom end of the drill cylinder 100, the drill cylinder 100 is convenient to insert into soil during sampling, the sampler is lifted by the extraction device 300 after sampling, the diameter of the drill cylinder 100 and the scale mark 104 on the pipe wall ensure the area and volume of sampling, the operation is simple and convenient, and the accuracy of sampling data is improved; when the soil animal sample needs to be taken out, the drill cylinder 100 is opened in half and filled into the bag, the complete original state of the soil animal sample is guaranteed, and the soil animal sample taking device is simple in structure, convenient to carry, good in using effect and easy to popularize and use.
Wherein, the bottom end of the drill cylinder 100 is provided with an opening shape, and the top end of the drill cylinder 100 is provided with a drill cover 105. Preferably, the drill cover 105 is composed of two half-covers 106, the two half-covers 106 being fixed by snap-fitting. In actual manufacturing, one half cover 106 is fixed to the first half pipe 101, one half cover 106 is fixed to the second half pipe 102, and the two are combined into the drill cover 105 by snap-fitting. Since some harder soil is often encountered when sampling soil, the sampler needs to be hammered into the soil, which may damage the drill barrel 100 if the drill barrel 100 is directly tapped. By arranging the drill cover 105, the drill cover 105 is directly knocked during knocking, and the safety of the drill cylinder 100 is ensured. The drill cover 105 is formed by combining two half-covers 106, and the drill cover 105 is combined together when the drill barrel 100 is combined, so that the drill cover 105 is not required to be combined additionally, and the operation is simple.
In this embodiment, fastener 200 includes female opening 201 and male opening 202 that are cooperatively secured. The concave bayonet 201 and the convex bayonet 202 on the first half pipe 101 are arranged in a staggered manner, and the convex bayonet 202 and the concave bayonet 201 which are arranged corresponding to the concave bayonet 201 and the convex bayonet 202 of the first half pipe 101 are arranged on two sides of the second half pipe 102. After the first half pipe 101 and the second half pipe 102 are assembled, the concave bayonet 201 and the convex bayonet 202 on the two half pipes are matched tightly without a gap.
In this embodiment, the graduation marks 104 are spaced apart by 5 cm. Specifically, the drill cylinder 100 is provided with 6 scale marks 104, which are marked as 5cm, 10cm, 15cm, 20cm, 25cm and 30cm in sequence from the cutting edge 103 to the direction of the drill cover 105. According to the scale marks 104, samples of soil animals at different depths can be taken according to actual needs during sampling.
In this embodiment, the concave bayonet 201 and the convex bayonet 202 are respectively arranged at 15cm and 30cm of the graduation mark 104. The inner diameter of the drill cylinder 100 is 2-5cm, the sectional area of the drill cylinder 100 is suitable for collection and statistics of medium and small soil animal communities, and the length of the drill cylinder 2 is 45-60 cm. Optionally, the drill barrel 100 is 50cm in length. By providing drill barrels 100 of different internal diameters and lengths, selection may be made as desired. Mainly adopts a sampler with a drill cylinder 100 and an inner diameter of 5cm for samples of small and medium-sized soil animals; the physical and chemical properties and the capacity of the soil, the porosity, the water content and other test indexes can be adopted, and an undisturbed soil sample which needs special requirements of a complete soil layer can be taken, so that a sampler with the inner diameter of the drill cylinder 100 of 2-3cm can be used, and the application range is greatly enlarged.
The extraction device 300 is an extraction hole arranged at the top end of the drill barrel 100, and the extraction holes are symmetrically arranged at two sides of the top end of the drill barrel 100. In the present embodiment, the extraction holes are preferably two, i.e., one on each half pipe, and when the two half pipes are combined into the drill barrel 100, the two extraction holes are oppositely disposed.
In one embodiment, the drill barrel 100 is made of an alloy. The sampler of alloy material not only can not cause the pollution to soil animal sample, simultaneously because the material is hard, the sampler is difficult for bending, warp, can effectively guarantee life.
When this small-size soil animal sampler is in actual use, to different soil, there are two kinds of sampling methods, specifically are:
1. pressing in method: on the premise of ensuring that the undisturbed soil sample is taken, the sampler is pressed down on the soil surface, then the sampler is lifted by the extraction device 300, and the undisturbed soil animal sample in the drill cylinder 100 can be taken out by opening the drill cylinder 100 in half. The method is rapid and convenient to operate, can reduce disturbance to soil animals, and is only suitable for sampling the soil animals with softer sections and the depth of 0-10 cm.
2. The driving method comprises the following steps: is generally suitable for sampling harder and harder soil animals. The driving method is that a hammer is used to knock the drill cover 105 of the sampler, so that the sampler reaches the depth of the soil layer to be collected, the sampler is extracted by the extraction device 300, and the undisturbed soil animal sample in the drill cylinder 100 can be taken out by opening the drill cylinder 100 in half. The method has high efficiency, and ensures the integrity of undisturbed soil animal samples, and is generally adopted.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
