Problems solved by technology

The disadvantage is that the sampling tube is a long tube. If the soil layer to be taken out is located in the middle of the sampling tube, the soil layer at both ends must be removed first. Impact
Second, if you want to collect deeper soil samples, the sampling tube is relatively long, which is not easy to carry
So far, there is no segmented sampling pipe in the prior art.

Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-3 As shown, a soil stratified sampling device includes a sampling tube 1, a sleeve head 2 is provided at the upper end of the sampling tube 1, and a ring cutter head 3 is provided at the lower end, and the sampling tube 1 is connected by several sections of detachable circular tubes 11. The round pipe 11 is threaded to facilitate disassembly. There is a narrow slit 12 in the axial direction of the round pipe 11 that runs through the wall of the round pipe 11. When in use, the corresponding size mark engraved on the round pipe 11 can be used according to the size of the soil to be sampled. Depth, select some round pipes 11 to combine to get the required length; the ring cutter head 3 is connected with the outer thread of...

Abstract

The invention discloses a stratified sampling device for soil, belonging to the technical field of instruments in agriculture and forestry. The stratified sampling device is used to solve the problem that the sampling tube of the existing stratified sampling device for soil cannot sample in sections, and is imprecise to sample and inconvenient to carry. The stratified sampling device for soil comprises the sampling tube, wherein a sleeve head is arranged at the upper end of the sampling tube while a circular tool bit is arranged at the lower end of the sampling tube. The sampling tube is formed by connecting a plurality of detachable circular tubes. As the stratified sampling device for soil disclosed by the invention is detachable, the stratified sampling device for soil is not only convenient to carry, but also samples in sections in one-time sampling. When a to-be-analyzed soil layer sample is taken away, samples in the sections in the sampling tube do not interfere with each other, so that the data integrity of the soil sample is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry instruments, and in particular relates to a soil layered sampling device. Background technique [0002] At present, in the fields of planting, soil and water conservation, and infrastructure construction, it is often necessary to sample the soil in layers first, and then analyze the soil samples. There are three common stratified collection methods for soil samples: [0003] One is the soil layer excavation method: first excavate the soil layer to be collected to a layer, then use the soil stratification ring knife to directly collect the required soil samples, and then continue to excavate to the lower layer that needs to be collected, and also use the soil stratification The ring knife collects the required soil samples, and so on. [0004] The other is the electric drilling method: use the soil sampling drill to go deep into the soil layer that needs to be sampled by electri...
