It can accurately measure soil moisture content and soil moisture characteristics, and can be widely used in the determination of soil moisture characteristics of farmland with diverse soil layers.

Description

A fixed volume soil drilling drill

Technical field:

The utility model relates to the field of farmland water conservancy with complex soil layer structure, in particular to a fixed volume soil drilling drill.

Background technique:

In view of the importance of soil to the survival and development of human beings, the study of the physical and chemical properties and water characteristics of soil has always been the basic work in the field of agriculture, and the soil drill is an indispensable tool for collecting soil samples. At present, most of the common soil-borrowing drills are integrated. First, the material is mostly cast iron, which is easy to rust. When soil is extracted, not only the rust on the surface increases the frictional resistance when it penetrates into the soil layer, but also pollutes the soil sample, affecting The accuracy of sampling; secondly, the drill bit is integrated with the soil-borrowing container, and it is difficult to take out the soil sample from the soil-borrower after being taken out, and it is easy to cause structural damage to the soil sample when separated; thirdly, the general sealed soil-borrowing drill takes out The layering of the sample cannot be clearly observed; fourth, in soils with higher hardness, or soils with larger bulk density, and soils with stronger viscosity, it is more difficult to penetrate into the soil layer, and it is difficult to drill manually. Therefore, be badly in need of a kind of earth-taking drill that can accurately, simply, easily sample.

Invention content:

The technical problem to be solved by the utility model is how to overcome the deficiencies of the prior art, provide a complete soil column that can take multiple soil layers of different depths at one time, basically do not destroy the lithology and structure of the soil, and can prevent the loss of water, The utility model is a soil auger capable of accurately measuring soil moisture content and soil moisture characteristics.

Realize the technical scheme of the utility model:

A fixed-volume soil-borrowing drill, which consists of a drill handle, a drill rod, two semicircular soil-borrowing containers, and a drill bit; the lower end of the drill rod is a circular concave fixing groove, which connects two symmetrical semicircular The sampling piece is fixed by a small screw, and the lower part is also connected and fixed with the drill bit; the soil sampling container is composed of two semicircular steel sheets, which together form a hollow cylinder, and the inner diameter is the same as that of a common sampling ring cutter. The length is 50cm. The connection between the sampling container and the fixed groove is fixed by small screws, and a small wrench is specially equipped for easy disassembly.

Further, the drill shank, drill bit, drill pipe, and soil-borrowing container are made of stainless steel, and the outside of the drill shank is covered with a drill shank sleeve made of rubber.

Further, the soil collection container is composed of two semicircular steel sheets, which together form a hollow cylinder with an inner diameter of 5.1 mm and a length of 50 cm.

Further, both the drill bit and the drill rod have concave fixing grooves, which are connected and fixed with the soil-taking container by small screws, the internal diameter of the drill bit is consistent with the sampling container, and the bottom of the drill bit has a slope-like structure.

The utility model has the advantages of how to overcome the deficiencies of the prior art, can take out a complete soil column with a certain depth of soil with diverse soil layers at one time, can clearly distinguish the boundary points of soil layers of different components, and basically does not damage the lithology and properties of the soil. The structure can prevent the loss of water, can accurately measure the soil moisture content, measure the soil moisture characteristics, and can be widely used in the determination of the soil moisture characteristics of farmland with diverse soil layers.

detailed description:

Example:

A fixed-volume soil-borrowing drill, which includes a drill handle 1, a drill rod 2, two semicircular soil-borrowing containers 3, a drill bit 4, and a small screw 5 and a small wrench. The length of the drill rod 2 is 60cm , the lower end is a circular concave fixing groove, connecting two symmetrical semicircular sampling 3 with a length of 50cm, an inner diameter of 50.46mm, and a volume of 1000cm ³ , connected and fixed by a small screw 5 with a length of 4mm and a diameter of 2mm, and the lower part is also Connect and fix by drill bit 4, described drill shank, drill bit, drill pipe, sampling container, small screw, small wrench are made of stainless steel, and described soil collection container is made up of two semicircular steel sheets, and thickness is 4mm, and length is 50cm Together it becomes a hollow cylinder, the bottom of the drill bit is a landslide structure to facilitate soil cutting, the connection between the sampling container and the fixing groove is fixed by small screws, and a small wrench is specially equipped for easy disassembly.

When in use, after the soil auger is installed, first take a 50cm deep soil sample, stabilize the drill handle, use a rubber hammer to directly smash the drill bit into the soil, and turn the drill bit clockwise a few times until the viscosity between the soil borrower and the soil profile changes. Small, take out the soil borrow drill, remove all the small screws with a small wrench, separate the soil borrow container from the drill bit and drill pipe, and then separate the soil borrow container into two pieces, you can get a complete 50cm deep soil column, select the The required soil is divided with a blade, put into an aluminum box and packaged for testing.

If another 80cm deep soil sample is taken, install the soil auger, smash it into the soil at the original sampling hole, wait until the soil auger hits 80cm into the soil, take out the soil auger, and you will get a 50cm-80cm deep sample. Soil samples are obtained in the same way for testing.
