Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of soil detection sampling, in particular to a deep soil detection equipment. BACKGROUND

[0002] Soil sample collection is an important link in soil detection technology, and soil sample collection equipment, as the basis and carrier of soil sampling technology, is indispensable in soil sampling. The soil sample collection equipment should meet the requirements as much as possible, and should try to make the obtained soil sample closer to the original state, thereby facilitating soil fertility determination, soil structure judgment, bulk density determination and soil structure analysis, etc. However, the existing deep soil detection sampling equipment still has the following shortcomings:

[0003] 1. When obtaining soil samples, the sampling tube is generally impacted or rotated by itself to enter the soil. Since the soil sample is always attached to the inner wall of the sampling tube, the soil sample is always subjected to the friction and rotational disturbance of the inner wall of the sampling tube as the sampling tube travels and rotates in the soil. In this case, the original state of the soil sample cannot be guaranteed, thereby affecting the quality of the soil sample sampling. Although the installation of a sampling head with an inner diameter smaller than that of the sampling tube on the sampling tube can overcome this problem, the sampling tube of this form will squeeze part of the upper layer of soil to the lower layer during the downward movement in the soil, causing contamination of the upper and lower layers of soil, thereby affecting the accuracy of soil detection.

[0004] 2. The existing soil sample detection and collection equipment needs to discharge the upper layer of soil multiple times when collecting deep layer soil samples. After collecting the soil sample at the predetermined depth position, the soil at the sampling position needs to be manually backfilled and restored, which is a relatively cumbersome operation procedure.
