Description

Sandy soil sampler

Technical Field

The utility model relates to a soil sampler technical field, especially a sandy soil sampler.

Background

The earth auger is the most common soil sample collecting tool and can accurately collect soil samples at different depths and different levels of soil. For loamy or clayey soils, the earth auger is labor-saving and efficient, but for sandy soils the following problems are common: because sandy soil porosity is big, loose, is difficult for forming soil aggregate, does not agglomerate, when using ordinary geotome (soil auger) to borrow soil, sandy soil can usually drop from the soil auger because of the action of gravity, causes the sample quantity inaccurate to cause the sample error. If a spade or other tools are used for soil sampling instead, the consistency of the up-and-down sampling quantity of the soil body cannot be ensured although the soil sampling is convenient, and finally the representativeness of the soil sample is greatly discounted.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the invention provides a sandy soil sampler which can solve the problem that sandy soil is difficult to accurately collect.

In order to achieve the purpose, the utility model adopts the technical proposal that:

the utility model provides a sandy soil sampler, includes sampling tube, handle and activity sheetmetal, and wherein the sampling tube is the siphonozooid of triangular prism form, the top at the sampling tube is installed to the handle, a lower edge of sampling tube lower extreme passes through articulated shaft articulated activity sheetmetal, and activity sheetmetal is separated into first half page or leaf and second half page or leaf by the articulated shaft, second half page or leaf is triangle-shaped, second half page or leaf can seal the lower extreme at the sampling tube after passing through the articulated shaft rotation.

Preferably, the upper half sheet is a square sheet.

Preferably, the upper half leaf is inclined gradually to the direction away from the sampling pipe from the hinged shaft to the top end.

Preferably, the upper half leaf and the lower half leaf are both straight leaves, and the upper half leaf and the lower half leaf are bent at a hinge shaft.

Preferably, the lower half sheet is a straight sheet, the upper half sheet is a curved sheet, and the top of the upper half sheet is bent towards the direction away from the sampling tube.

Preferably, the top end of the upper half sheet is a knife-edge side edge.

Preferably, the outer edges of the lower half sheet are all in a blade shape.

Preferably, the movable metal sheet is a thin-walled metal sheet.

Use the utility model discloses a beneficial effect is:

this sampler can the disect insertion to sandy soil in, and at the in-process of inserting downwards, because first half leaf in the activity sheetmetal receives the resistance adduction, therefore second half leaf is in upright state, and after the sampling tube inserted the predetermined degree of depth, the soil of taking a sample was stayed in the sampling tube. When the sampler is lifted upwards, the upper half leaf piece is subjected to resistance and expands outwards to drive the lower half leaf piece to be closed at the lower end of the sampling tube, so that sampled soil is closed in the sampling tube, and the purpose of blocking the lower interface to prevent sandy soil from falling is achieved.

Detailed Description

In order to make the purpose, technical solution and advantages of the present technical solution clearer, the present technical solution is further described in detail below with reference to specific embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present teachings.

Example 1

As shown in fig. 1-4, the present embodiment provides a sandy soil sampler, which comprises a sampling tube 10, a handle 20 and a movable metal sheet 30, wherein the sampling tube 10 is a tubular body in a triangular prism shape, the handle 20 is mounted on the top end of the sampling tube 10, a lower edge of the lower end of the sampling tube 10 is hinged to the movable metal sheet 30 through a hinge shaft 40, the movable metal sheet 30 is divided into an upper half sheet 31 and a lower half sheet 32 by the hinge shaft 40, the lower half sheet 32 is triangular, and the lower half sheet 32 can be closed at the lower end of the sampling tube 10 after rotating through the hinge shaft 40.

In this embodiment, the upper half sheet 31 is a square sheet, and the area of the upper half sheet 31 is larger than that of the lower half sheet 32.

The upper half flap 31 is gradually inclined from the hinge shaft 40 to the tip in a direction away from the sampling tube 10.

The sampler can be directly inserted into sandy soil, in the process of downward insertion, because the upper half leaf 31 in the movable metal sheet 30 is retracted by resistance, the three lower half leaves 32 are separated from each other, and after the sampling tube 10 is inserted to a preset depth, the sampling soil is retained in the sampling tube 10. When the sampler is lifted up, the upper half leaf 31 is subjected to resistance and expands outwards, the three lower half leaves 32 are driven to be mutually closed to form a triangular cone shape, and the sampled soil is sealed in the sampling tube 10, so that the purpose of blocking the lower interface and preventing the sandy soil from falling is achieved.

Because the sampling tube 10 uses the hollow triangular prism body, rather than the conventional cylinder, this is because the sandy soil texture is light, and it is not hard to get soil itself, need not to prick easily through rotatory soil drill, and the design of sampling tube 10 triangular prism, its cross section is triangle-shaped realizes more easily that it connects movable metal sheet 30 through articulated shaft 40.

The purpose of the movable metal sheet 30 is to plug the lower end of the sampling tube 10 in time when the earth drill is lifted up to the target depth. In this embodiment, the upper half sheet 31 and the lower half sheet 32 are both straight sheets, and the upper half sheet 31 and the lower half sheet 32 are bent at the hinge shaft 40 to realize the automatic turnover of the sliding metal sheet when the sampling tube 10 is lifted up. As shown in FIG. 6, when the coupon 10 is pressed down, the upper sheet half 31 is forced against the coupon 10 and the lower sheet half 32 is in a substantially upright position. As shown in FIG. 7, when the sampling tube 10 is lifted, the surrounding soil automatically moves to one side of the movable metal sheet 30, so as to achieve the purpose of blocking the lower interface and preventing the sand from falling.

The top end of the upper half sheet 31 is a knife-edge side edge.

The outer edges of the lower half-leaf 32 are all knife-edge shaped.

The movable metal sheet 30 is a thin-walled metal sheet.

Example 2

This embodiment is similar to the proposed sandy soil sampler, except that the upper half-leaf 31 is curved in configuration.

As shown in fig. 5, the lower half-sheets 32 are straight sheets, the upper half-sheets 31 are curved sheets, and the top of the upper half-sheets 31 is bent away from the sampling tube 10, so that the lower half-sheets 32 can more easily achieve the desired effect no matter the upper half-sheets 31 move up or press down on the sampling tube 10.

The foregoing is only a preferred embodiment of the present invention, and many variations can be made in the specific embodiments and applications of the present invention by those skilled in the art without departing from the spirit of the present invention.
