Embodiment Construction

[0015] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Depend on Figure 1 to Figure 8 Given, the present invention includes a vertical bar 1, the lower end of the vertical bar 1 is equipped with an outer barrel 2 coaxial with the vertical bar 1 and with an upward opening, and the outer barrel 2 is equipped with a barrel that coincides with the axis of the outer barrel 2 and can be moved along the vertical axis. The cylindrical casing 3 that the rod 1 moves up and down, the first torsion spring is installed between the casing 3 and the vertical rod 1, when the casing 3 is at the bottom of its displacement, the first torsion spring can drive the casing 3 to rotate, and the casing The circumference of the upper end surface of the 3 is evenly distributed with a plurality of feeding ports 5 that penetrate up and down. The vertical rod 1 is equipped with a second sleeve 6 ...

Abstract

The invention relates to an efficient soil sampling device so as to effectively solve the problems of inaccuracy in sampling, complicated operation and low sampling efficiency of the existing device.The efficient soil sampling device comprises a vertical rod, wherein an outer drum is arranged on the vertical rod; a shell is arranged in the outer drum; a torsional spring is arranged between the shell and the vertical rod; a material inlet is formed in the shell; a second sleeve is arranged on the vertical rod; a torsional spring is arranged between the second sleeve and the vertical rod; a third sleeve is arranged on the vertical rod; a convex block is arranged on the third sleeve; a bushing is arranged on the vertical rod; the bushing is located below; the third sleeve is fixed; a cavityof the shell is closed; the bushing drives the vertical rod, the shell, the outer drum and the second sleeve to rotate; the bushing moves upwards, and then the third sleeve is released and moves downwards; later, the torsional spring drives the third sleeve to rotate, and the cavity of the shell is opened; after moving downwards, the shell rotates; after the shell rotates, the cavity of the shellis closed. The efficient soil sampling device disclosed by the invention can efficiently sample soil at a specific depth, and the sample cannot be polluted by soil samples on other depth layers.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to a high-efficiency soil sampling device. Background technique [0002] The earth taker is used to lift the undisturbed soil of the lower layer of the test soil as a sample to understand its properties. In order to better understand the nature of the base, sometimes the original soil sample is taken at a deeper level. It is called a soil extractor. However, most of the traditional soil extractors are simple in structure and laborious to use, and the traditional soil extractors are not accurate enough to collect soil samples, which makes it difficult to meet people's needs. In addition, when it is necessary to collect deep soil samples, manual excavation It is too labor-intensive to dig a hole to a certain depth for sampling. Therefore, an efficient soil sampling device is urgently needed to solve the problems of inaccurate sampling, complicated operation, low sampling effic...
