Description

Technical Field

[0001] The utility model relates to the technical field of soil sample collection, and particularly relates to a portable soil sampler for alpine soil. Background Art

[0002] Soil samplers play an important role in modern agriculture, environmental protection and geological research. Through accurate soil sampling, researchers can analyze key information such as soil composition, structure, nutrient content, etc.

[0003] For alpine grassland ecological experiments, a soil sampler with little damage is essential. Currently, the most commonly used soil sampler is a soil drill. The drill bit is inserted into the soil by rotating and pressing downwards to collect soil. Since alpine soil has strong toughness and is not easy to be damaged, such as mat soil and black mat soil; and it is difficult to take out the soil from the drill bit. In addition, the oxygen is thin at high altitudes, making the sampling process time-consuming and laborious. Moreover, the alpine soil layer is shallow, and the soil sampling depth is generally less than 30 cm. The existing soil drills are relatively long and inconvenient to carry. Summary of the Utility Model

[0004] The utility model aims to provide a portable soil sampler for alpine soil to solve the problems of inconvenient carrying of the current soil sampler and time-consuming and laborious alpine soil sampling process.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A portable soil sampler for alpine soil, comprising: a sampling cylinder, a handle and a hammer head. The inside of the sampling cylinder is hollow. An arc-shaped cutter is provided at the bottom of the sampling cylinder. A soil pushing port is provided on the side wall of the sampling cylinder. The hammer head is fixed at the top of the sampling cylinder. The handles are symmetrically arranged on both sides of the hammer head. The handles are hollow. A through hole is provided on the hammer head. The through hole communicates with the two ends of the handles to form a tool hole. A soil pushing member is placed in the tool hole. The circular arc-shaped tip of the arc-shaped cutter can form a larger pressure to make it better insert into the soil.

[0006] Further limited, the edge of the arc-shaped cutter is serrated. The serrated blade can more easily cut off plant roots, which is beneficial to soil sampling in alpine grasslands.

[0007] Further limited, an anti-slip sleeve is sleeved on the handle. The anti-slip sleeve closes the end of the handle and is convenient for the staff to hold the handle for soil sampling.

[0008] Further limited, the soil pushing member is an iron bar. The iron bar is not easy to deform and is convenient for quickly pushing out the soil in the sampling cylinder.

[0009] Further limited, a magnet is fixed in the handle or the through hole of the hammer head. The magnet is used to adsorb the iron bar, which is convenient for fixing and placing the iron bar.

[0010] Further limitation: a protrusion is provided at the end of the handle to prevent the hand from slipping off the handle when applying force.

[0011] Further limitation: the earth-pushing opening is strip-shaped.

[0012] Further limitation: a cylindrical protective cover is also provided on the sampling cylinder, and the protective cover is used to prevent damage to the cutting edge during handling.

[0013] Further limitation: the arc-shaped cutting knives are symmetrically arranged on the sampling cylinder, and the connection part of the arc-shaped cutting knives has a smooth transition. The smooth transition at the connection part of the two arc-shaped cutting knives reduces stress concentration and avoids fracture at the joint of the two cutting knives during the use of the sampler.

[0014] Further limitation: the hammer head includes a striking part, a fixing part and a connecting part from top to bottom. The fixing part is hollow, the fixing part and the connecting part are fixedly connected, the through hole is provided on the fixing part, and the striking part is fixedly connected to the fixing part in a detachable manner.

[0015] The beneficial effects of the present utility model are as follows: when in use, the soil sampler can be inserted into the soil by striking the hammer head, which is convenient for sampling in tough and hard soils; the symmetric double arc-shaped cutting knives at the bottom of the sampler make it not easy for the sampling cylinder to tilt when entering the soil; the earth-pushing openings on both sides of the sampling cylinder enable tools such as iron bars to pass through the sampling cylinder to smoothly push out the soil; it can be used for sampling the surface soil of loose soil; the device is easy to use, has a simple structure, is convenient to carry, and is suitable for popularization and use.

[0019] The following is a further detailed description through specific embodiments:

[0020] The reference numerals in the accompanying drawings of the specification include: hammer head 1, handle 2, earth-pushing opening 3, sampling cylinder 4, arc-shaped cutting knife 5.

[0021] Embodiment:

[0022] A portable soil sampler for alpine soil, as shown in the attached Figure 1 、 attached Figure 2 and attached Figure 3As shown in the figure, it includes a sampling cylinder 4, a handle 2, and a hammer head 1. The hammer head 1 is fixed to the top of the sampling cylinder 4. The hammer head 1 is made of a relatively thick hard alloy material, specifically composed of 3-4 mm 304 stainless steel material, with the function of resisting knocking, not easily deformed under force, and having a long service life.

[0023] The hammer head 1 includes a knocking part, a fixing part, and a connecting part from top to bottom. The fixing part is hollow, specifically a hollow cylinder with a diameter of 3-4 cm, smaller than the diameter of the sampling cylinder 4, and a height of about 5 cm. Both the connecting part and the knocking part are thick round gaskets. The diameter of the connecting part is the same as the diameter of the sampling cylinder 4, and the diameter of the knocking part is the same as or larger than the diameter of the fixing part. The fixing part and the connecting part are fixedly connected, specifically by welding, and a through hole is provided on the fixing part. The knocking part is detachably fixed to the fixing part, specifically by bolts or by engaging with corresponding protrusions and grooves.

[0024] The handles 2 are symmetrically arranged on both sides of the hammer head 1. The handles 2 are hollow. There are through holes on the hammer head 1, and the through holes communicate with the two ends of the handles 2 to form a tool hole. A soil pushing piece is placed in the tool hole. The soil pushing piece is used to push the soil in the sampling cylinder 4 through the sampling cylinder 4. The soil pushing piece is an iron bar or an iron cone. A magnet is fixed inside the handle 2 or in the through hole of the hammer head 1 to adsorb the iron bar, facilitating the fixed placement of the iron bar.

[0025] An anti-slip sleeve is sleeved on the handle 2. The anti-slip sleeve closes the end of the handle 2 and at the same time facilitates the staff to hold the handle 2 for soil sampling. In this embodiment, the anti-slip sleeve is made of rubber. A protrusion is provided at the end of the handle 2 to prevent the hand from slipping off the handle 2 when exerting force.

[0026] The inside of the sampling cylinder 4 is hollow. The diameter of the sampling cylinder 4 is 4-5 cm, and the height is about 32 cm. It is marked every 10 cm from the bottom to the top. The inner wall of the sampling cylinder 4 is smooth, and the thickness is 0.5-3 mm.

[0027] On the side wall of the sampling cylinder 4, soil pushing ports 3 are symmetrically provided. Along the axial direction of the sampling cylinder 4, there is at least one group of symmetrically arranged soil pushing ports 3, and the preset length spaces of adjacent groups of soil pushing ports 3 overlap. This makes the soil pushing ports 3 communicate with each other, facilitating the pushing out of the soil in the sampling cylinder 4 with the help of the soil pushing piece. The connection lines of adjacent groups of symmetrically arranged soil pushing ports 3 are not in the same plane, and the soil pushing ports 3 are strip-shaped. In this embodiment, two groups of symmetrically arranged soil pushing ports 3 are provided along the axial direction of the sampling cylinder 4. The upper symmetric long-strip soil pushing ports 3 on the sampling cylinder 4 start from 1-2 cm from the top of the sampling cylinder 4. The width of the soil pushing ports 3 is about 2 cm, and the length is about 12 cm. The size of the lower soil pushing ports 3 is the same as that of the upper ones. The bottom end of the upper soil pushing ports 3 coincides with the top end of the lower soil pushing ports 3 by about 2 cm, so that tools such as iron bars can smoothly pass through the sampling bucket to smoothly push out the soil.

[0028] At the bottom of the sampling cylinder 4, arc-shaped cutting blades 5 are symmetrically arranged. An inverted V-shaped soil-pushing opening is formed between the symmetric arc-shaped cutting blades 5, which is conducive to the arc-shaped cutting blades 5 breaking through the soil and facilitating the soil to enter the sampling cylinder 4. The connection between the two arc-shaped cutting blades 5 has a smooth transition to reduce stress concentration and avoid fracture at the joint of the two cutting blades during the use of the sampler.

[0029] The blade part of the arc-shaped cutting blade 5 is serrated. The serrated blade can more easily cut off plant roots, which is beneficial for soil sampling in alpine grasslands.

[0030] A cylindrical protective cover is also provided on the sampling cylinder to prevent damage to the blade part during handling. Specifically, an annular groove is provided above the installation position of the arc-shaped cutting blade on the sampling cylinder for installing the protective cover.

[0031] Specific implementation process:

[0032] During operation, when sampling alpine soil with strong toughness is required, the staff holds the handle 2 with both hands, places the arc-shaped cutting blade 5 on the soil surface, presses the device downward to make the arc-shaped cutting blade 5 insert into the soil. Subsequently, the staff uses tools such as a rubber hammer to strike the hammer head 1, while striking and turning the handle 2 until the sampling cylinder 4 reaches the sampling depth, and then pulls it upward to take out the sampler from the soil; insert a tool such as an iron bar that is not easily deformed into the long strip-shaped soil-pushing opening 3 to easily push out the soil embedded inside the sampling cylinder 4.

[0033] When this solution is used, the sampling cylinder 4 can be quickly inserted into the soil by means of external force knocking, and then the soil can be quickly pushed out by inserting an iron bar or an iron cone into the symmetric long strip-shaped soil-pushing opening 3 on the sampling cylinder 4, thus saving time and effort to complete the sampling. It is also possible to gently strike the hammer head 1 with a hammer before pushing out the soil to loosen the soil and the sampling cylinder 4, and then insert an iron bar into the sampling cylinder 4 to push out the soil, which can quickly take out the soil; this device is convenient to use, has a simple structure, is easy to carry, and is suitable for popularization and use; by knocking the hammer head 1, the soil sampler can be inserted into the soil, which is convenient for sampling in soil with strong toughness and hard texture, and can also be used for sampling the surface soil of loose soil; the symmetric double arc-shaped cutting blades 5 at the bottom of the sampler make it not easy for the sampling cylinder 4 to tilt when entering the soil; the double-sided simultaneous soil-pushing openings 3 on the sampling cylinder 4 enable tools such as iron bars to pass through the sampling cylinder 4 to smoothly push out the soil.
