Embodiment Construction

[0025] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0026] The soil sampling system of the present invention includes a sampler and a hole forming device, wherein the sampler includes four parts: a ring cutter sleeve, a ring cutter handle, a wire pulling device and a ring cutter;

[0027] Among them, the ring knife sleeve is a hollow square cylindrical structure with an open bottom, and its specific structure is as attached Figure 5 As shown, (a) is a side view, (b) is another side sectional view, and (c) is a top view. In this specific embodiment, the ring cutter sleeve 10 is made of steel, and the two side walls of its lower part There are symmetrical steel wire track grooves 15 along the horizontal direction, and a steel wire fixed slider 14 that can slide along the track groove is respectively embedded in the two steel wire track grooves 15, and a steel wire fixed slider 14 that is vertical to the s...

Abstract

The invention discloses a system for sampling soil and belongs to the technical field of agriculture agricultural water-soil engineering. The system for sampling soil comprises a sampler and a slot former, wherein the sampler comprises four detachable parts: a cutting ring sleeve, a cutting ring handle, a wire dragging device and a cutting ring; the slot former comprises a T-shaped handle and a rotating soil-cutting device which is fixedly connected to the lower part of the handle; and the rotating soil-cutting device is formed by oppositely welding two S-shaped steel sheets having cutting edges on the peripheries. On the basis of traditional cutting ring, the system for sampling soil provided by the invention is used for realizing the complete soil-cutting through upper and lower parts of the cutting ring, by utilizing an upper soil-cutting wire and a compass dragger to drive a lower soil-cutting wire, thereby avoiding the phenomenon of breaking or sticking soil after taking out the cutting ring and having minimum disturbance to the original soil. By combining with the slot former, the deep soil can be sampled without disturbance. The whole system has simple structure, is conveniently operated and has high sampling efficiency. The invention also discloses a method for sampling soil by using the system.

Description

technical field [0001] The invention relates to a soil sampling system, which belongs to the technical field of agricultural water and soil engineering. Background technique [0002] In the technical field of agricultural hydrotechnical engineering, soil sampling is often required. The traditional soil sampling method is to press the ring knife into the soil smoothly, and after the soil column in the ring knife emerges from the upper end of the ring knife, dig out the surrounding soil with a shovel, and take out the ring knife full of soil. When it is necessary to measure the deeper soil, it is necessary to excavate the soil surface in a large area, often to a depth of 1-2m. For cultivated soils, such large-area and high-intensity disturbed soils for raw soil sampling have a great impact on crop cultivation, so sampling time and sampling frequency are often limited, and traditional sampling methods are time-consuming, labor-intensive, and extremely inefficient. Therefore, ...
