In recent years, the development of agriculture in China is rapid, and in order to further develop agriculture, the improvement of grain yield and quality is required to continue the progress of agricultural technology in China. In agricultural science and technology and agricultural environment research, understanding and research on soil is attracting more and more attention from agricultural workers. Due to the nature of the soil itself and the diversity of the soil, there has been no ideal solution for how simple and efficient to obtain soil samples. In agricultural science and technology experiments, soil samples are often required to be collected to measure indexes such as soil moisture content, soil conductivity and PH value, and a soil sampler is an indispensable tool in the process of collecting the samples.

The soil sampler in the prior art has a simple structure and is convenient to carry, but in the use process, the soil sampler is mostly required to be used by being matched with a hammer for knocking, for example, in the Chinese patent document with the bulletin number of CN202757795U, CN202757795U, the soil sampler is provided with a structure for knocking by the hammer, so that the soil sampler is drilled below the ground surface. It is known that in farmland, although the soil is much softer than the hard field, it is difficult to insert the sampler directly into the subsoil layer below the topsoil, mainly for two reasons: firstly, soil is gradually compacted, the soil is not easy to drill into, secondly, in the process of drilling the soil sampler, more and more soil in the soil sampler pipe is gradually compacted, the deeper the soil is, the smaller the space in the pipe is, and the soil sampler is difficult to continuously descend. The proposal in the prior art mainly solves the first condition and has little relation to the second condition, and therefore, the utility model provides a portable soil sampler.

Detailed Description

For a clearer understanding of technical features, objects and effects of the present utility model, a detailed description of embodiments of the present utility model will be made with reference to the accompanying drawings.

Example 1

As shown in fig. 1, a portable soil sampler comprises a soil sampling pipe 1, wherein a vertical rod 2 is arranged at the top of the soil sampling pipe 1, a grip 3 is arranged at the top of the vertical rod 2, the soil sampling pipe 1 is of a tubular structure with an opening at the bottom, a soil discharging mechanism is arranged on the soil sampling pipe 1, and the soil discharging mechanism comprises a soil discharging groove 5 formed in the side wall of the soil sampling pipe 1.

The soil discharge groove 5 is of a U-shaped structure and penetrates through the side wall of the soil taking pipe 1, the bottom of the soil discharge groove is open, the soil discharge groove 5 is located on two sides of the soil taking pipe 1, when the soil taking pipe 1 is used for exploring downwards, soil enters the soil taking pipe 1, the soil can be compressed generally, therefore, when the soil fills the soil taking pipe 1, the soil firstly enters the soil taking pipe 1 and is extruded by the soil subsequently entering the soil taking pipe 1, and the soil is discharged from the soil discharge groove 5.

The soil discharging mechanism further comprises a soil dividing block 4 which is arranged inside the soil taking pipe 1 and used for dividing soil to the soil discharging groove 5.

The soil dividing block 4 is positioned at the top of the inner side of the soil taking pipe 1, and the soil dividing block 4 is used for dividing soil and then discharging the soil from the soil discharging groove 5, and the soil has certain viscosity, particularly the viscosity of the compressed and compacted soil is increased, so that the soil is divided by the soil dividing block, and is convenient to discharge from the soil discharging groove 5.

The soil dividing block 4 comprises a triangular wedge block 6 arranged in the middle, the side surface of the triangular wedge block 6 is in an isosceles triangle shape, one edge of the triangular wedge block 6 faces downwards, and inclined surfaces which are symmetrical on two sides face the soil discharging groove 5.

Specifically, the top edge (the edge at the vertex of the isosceles triangle) of the triangular wedge block 6 faces downwards, and forms a blade structure with the inclined planes at two sides (the two sides at the waist edge of the isosceles triangle), so that the soil entering the soil sampling pipe 1 is separated towards the direction of the soil discharge groove 5, and the soil is conveniently discharged from the soil discharge groove 5.

The soil dividing block 4 further comprises guide wedges 7 arranged on two sides, the outer diameter of each guide wedge 7 is identical to the inner diameter of the soil taking pipe 1, the guide wedges 7 and the triangular wedges 6 enclose a guide groove 8 with the extending direction facing the soil discharging groove 5, and the width of each guide groove 8 is identical to the width of the soil discharging groove 5.

After the soil is separated by the soil dividing blocks 4, the soil is extruded along the guide grooves 8 to flow to the soil discharging grooves 5 and is discharged, the guide wedge blocks 7 are used for filling the space area between the inclined planes of the triangular wedge blocks 6 and the inner wall of the soil taking pipe 1 to the soil discharging grooves 5, so that the soil is prevented from being accumulated in the area, and the smoothness of soil discharging is improved.

The lower part of the guide wedge block 7 is provided with an inclined plane structure, the top of the inclined plane structure is connected with the bottom of the triangular wedge block 6, the bottom of the inclined plane structure is connected with the side wall of the soil sampling pipe 1, and the section of the inclined plane structure is in an eight shape.

The inclined surface structure also plays a guiding role, soil in the soil taking pipe 1 firstly enters the inclined surface structure, gathers together from two sides to the middle under the guiding role of the inclined surface structure, and continuously flows along the guide groove 8 and in the direction of the soil discharging groove 5 after the gathered soil continuously contacts the triangular wedge block 6 upwards, so that the smoothness of the soil discharged from the soil discharging groove 5 is further improved.

The triangular wedge block 6 and the guide wedge block 7 are of an integrated structure.

The integrated structure is manufactured, firstly, the production and the processing are convenient, and secondly, gaps are avoided between the triangular wedge blocks 6 and the guide wedge blocks 7.

The bottom opening of the soil taking pipe 1 is provided with a first blade part 9 with a downward cutting direction.

The soil taking pipe 1 is convenient to drill downwards.

The side wall of the soil discharging groove 5 is provided with second blade parts 10 which cut in both sides.

When the soil sampling pipe 1 reaches a specified depth, the soil sampling pipe 1 rotates left and right after required soil samples are obtained, the soil which is stuck together inside and outside the soil sampling pipe 1 is cut and separated from the soil discharge groove 5 through the second blade part 10, and when the soil sampling pipe is lifted upwards, the soil samples inside the soil stuck soil sampling pipe 1 outside the soil sampling pipe 1 are prevented from falling into the holes of the samples, and meanwhile, the resistance caused by the sticking between the outer side wall of the soil sampling pipe 1 and the soil when the soil sampling pipe is lifted upwards can be reduced.

Working principle: the device is pressed by the handle 3 (a hammer can be used for knocking the handle 3), the soil taking pipe 1 is drilled into a surface soil layer and continuously drilled downwards, in the drilling process, after the soil of the soil taking pipe 1 is piled up, the soil is separated from the triangular wedge block 6 under the extrusion action of the subsequent soil, and is discharged upwards from the top position of the soil discharging groove 5 after passing through the guide groove 8, so that the subsequent soil is convenient to continuously enter the soil taking pipe 1;

After the soil sample at the designated depth position is obtained, the soil sampling tube 1 is rotated, and then the soil sampling tube 1 is lifted up, and the soil sample is poured out.
