Description

Spiral soil sampler

Technical Field

The utility model relates to a hand tool, in particular to a spiral soil sampler.

Background

At present, soil taking devices are often used in agricultural or forestry hand tools, are mainly used for digging pits, take out soil in pits in the process of digging pits, facilitate the travel of the pits, and are mainly used for transplanting tree seedlings, inserting fences and other work.

At present, a plurality of soil extractors are widely used, wherein the most widely used soil extractor is a spiral soil extractor, for example, the soil extractor disclosed in the utility model patent of 'spiral static pressure undisturbed soil extractor (ZL 201811125856.6)' in China is that a long spiral soil cutting ring cutter is fixedly connected to the periphery of a sampling cylinder, the whole spiral is a spiral line, soil in a pit hole is conveyed in a rotating process through the soil cutting ring cutter in a rotating mode, and then the soil is extruded from the soil cylinder body. In long-term use, the cooperation of single helical blade and cutting ring is not enough to the cutting ability of soil, and the effect of loosening the soil is unsatisfactory, and whole geotome digs hole process intensity big, and the user wastes time and energy.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a to mention not enough in the background art, provide a cut native ability reinforce, excavate the dynamics big, the convenient spiral geotome of fetching earth.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows: a spiral soil sampler comprises a tool head part and a rod part which are fixedly connected together,

the tool head comprises at least two helical blades and a tip; the helical blades are uniformly and fixedly connected to the periphery of the lower end of the rod part; the tip part is of a plate-shaped structure, and the tip end of the tip part is of a rectangular pyramid structure.

As a preferred technical scheme: each helical blade is an independent blade body and is spirally wound on the periphery of the lower end of the rod part at the same circle center; a plurality of helical blades are enclosed into a circular structure.

As a preferable technical scheme: the free end of the helical blade is lower than the helix of the entire helical blade.

As a preferable technical scheme: the outer side of the helical blade is of a tooth structure, and the side surface of each tooth is an inclined surface.

As a preferable technical scheme: the inclination directions of the teeth on the outer sides of the helical blades are the same.

As a preferred technical scheme: the two sides of the tip are uniformly provided with sawteeth from top to bottom.

As a preferred technical scheme: the serrations become smaller from top to bottom.

Compared with the prior art, this kind of geotome utilizes the blade of a plurality of independent helices to constitute circular rotatory native blade, the tooth on blade periphery for unified inclined plane, rotatory in-process is strong to the cutting ability of soil behind the screw in soil, can change alone after a plurality of helical blade damage, the used repeatedly of being convenient for, the point portion is the pyramid structure, it is big to bury the dynamics, improve the excavating capacity, the blade tip has a down dip, help inserting in the soil, the most advanced of a plurality of blades is to soil multiple cutting, be convenient for loosen the soil, conveniently take out the soil in the pot hole.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Referring to fig. 1-3, the utility model discloses an improvement that this kind of geotome of disclosing is carried out on the basis of current spiral geotome, improves the long helical blade of a jump helix into the short helical blade of a plurality of helices, is two or three helical blade generally, is independent helix, and the equipartition is in the outside of body of rod lower extreme.

The tool head comprises at least two helical blades 2 and a tip part 3, and the tip part 3 is fixedly connected with the lower end of the rod part 1 into a whole. The bottom of the rod body is sealed, and the tip part is welded and fixed with the rod body.

In the present embodiment, the tip 3 has a plate-like structure, and the tip thereof has a rectangular pyramid structure, as shown in fig. 3.

As another preferred embodiment, see FIG. 4, the saw teeth are uniformly distributed on both sides of the tip part, the saw teeth decrease from top to bottom, and the directions of the tooth tips of the saw teeth are consistent.

In the embodiment, the lower end of the rod part 1 is provided with three helical blades 2, and each helical blade 2 is an independent blade body and is spirally wound on the periphery of the lower end of the rod part at the same circle center; three helical blade 2 encloses into a circular structure, and every helical blade's inboard all welds on the surface of pole portion lower extreme along its helix direction. If the number of the helical blades is two, the length of the helical blade is larger than that of the helical blade in the embodiment, and the outer sides of the two helical blades also enclose a circle.

In this embodiment the free end of the helical blade 2 is lower than the helix of the entire helical blade, see fig. 2 (the dotted line is the helix direction). The tip of the device is inclined downwards, so that the device is beneficial to inserting the pattern layer in the rotating process and cutting soil. And the outer side of the helical blade 2 is of a tooth structure, and the side surface of each tooth is an inclined surface. The incline direction of the teeth outside each helical blade is the same, each tooth inclined plane is edged, and at rotatory in-process, the tooth plays the sawtooth effect, cuts soil, realizes the effect of loosening the soil, and the soil that cuts down falls on the helical blade, outwards carries to draw whole geotome through the user and realizes borrowing.

According to actual production needs, the outer diameter of the circle surrounded by the whole helical blade can be of multiple specifications, and the outer diameter determines the inner diameter of the dug pit hole.

The soil sampler is mainly used for a hole required by seedling transplanting; holes required for fence landfill, and the like.
