Problems solved by technology

Because the conventional ring knife only has a flat circular blade, it is very laborious to press into the soil, and it must be dug out with auxiliary tools such as a shovel or a soil cutter, which is not only laborious but also destroys the surrounding soil environment

Embodiment 1

[0027] refer to figure 1 , the present invention provides a novel ring knife soil sampler, the sampler comprises a ring knife 1, a ring knife fixing sleeve 2 and a handle structure 3, the ring knife 1 includes a knife seat 4 and at least two blades 5, so The blades 5 are arranged at one end of the knife holder 4, and the blades 5 are arranged in concentric circles. The shape of the blades 5 is similar to a Luoyang shovel, so that it is more labor-saving to insert the blades 5 into the soil. 5 are arranged in concentric circles, forming a hollow cylinder, and by rotating the handle structure 3, the cylindrical soil body can be separated from the external soil body in the vertical direction, and a cylindrical soil body can be cut out. The knife seat 4 is fixedly connected with the ring knife fixing seat 2 , and the handle structure 3 is fixedly connected or integrally connected with the ring knife fixing sleeve 2 . In a preferred embodiment, the knife seat 4 is a circular knife...

Embodiment 2

[0030] refer to Figure 4 and Figure 5 , the present invention also provides a novel ring cutter soil sampler, embodiment 2 is basically the same as embodiment 1, the difference is that the ring cutter 1 is made up of four blades 5 and a knife seat 4, and the knife seat 4 is a circular knife seat, the blades 5 are arranged at one end of the knife seat 4, and the blades 5 are arranged in concentric circles, and the blades 5 are evenly distributed on the circumference, and the center of the concentric circles is the same as The centers of circles of the knife seat 4 coincide. In a preferred embodiment, the blade 5 and the knife seat 4 are integrally formed, and the material of the blade 5 and the knife seat 4 is stainless steel. The blade 5 has a cutting edge at its edge 6 . The cross-sectional area of ​​the blade 5 decreases gradually along the direction away from the blade seat 4 . The contact area of ​​the front end of the blade 5 first contacting the soil is small, which...

Embodiment 3

[0032] refer to Figure 6 and Figure 7 , the present invention also provides a novel ring cutter soil sampler, embodiment 3 is basically the same as embodiment 2, the difference is that the ring cutter 1 is made up of four blades 5 and a knife seat 4, and the knife seat 4 is a circular knife seat, the blades 5 are arranged at one end of the knife seat 4, and the blades 5 are arranged in concentric circles, and are evenly distributed on the circumference, the center of the concentric circles and the knife seat 4 coincides with the centers of circles. In a preferred embodiment, the cross-sectional area of ​​the blades 5 gradually decreases along the direction away from the knife seat 4. When the four blades 5 abut against the knife seat 4, One end is connected with each other to form a whole, and the blade 5 and the knife seat 4 are integrally formed, and the material of the blade 5 and the knife seat 4 is stainless steel.

Abstract

The invention discloses a novel ring knife soil sampler, the sampler includes a ring knife, a ring knife fixing sleeve and a handle structure, the ring knife includes a knife seat and at least two blades, the blades are arranged on the knife One end of the seat, and the blades are arranged in concentric circles, the knife seat is fixedly connected with the ring knife fixing seat, and the handle structure is fixedly connected or integrally formed with the ring knife fixing sleeve. The shape of the blade is similar to that of a Luoyang shovel, which makes it easier to enter the soil. By rotating the handle structure, the columnar soil body can be separated from the external soil body in the vertical direction, and then the handle structure can be shaken left and right to make the columnar soil body taken It is separated from the external soil in the horizontal direction, and the soil can be taken out by lifting the sampler, without the need for auxiliary tools to dig out the ring knife, and will not cause damage to the surrounding soil environment.

Description

technical field [0001] The invention relates to a soil sampling tool, in particular to a novel ring cutter soil sampler. Background technique [0002] The ring knife is used to take the undisturbed soil and is a commonly used instrument that is indispensable for soil density, compression, shear and penetration tests. The conventional ring knife soil sampling method is to first determine the position and dig a soil profile, and then take samples in layers according to the profile level. Or the soil cutting knife cuts the soil around the ring knife, takes out the ring knife filled with soil, wipes the outer soil of the ring knife clean, and preserves the soil. Because the conventional ring knife has only one smooth circular blade, it is very laborious to press into the soil, and it must be dug out with auxiliary tools such as a shovel or a soil cutter, which is not only laborious but also destroys the surrounding soil environment. Contents of the invention [0003] The tec...
