Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the preferred embodiments described herein are for purposes of illustration and understanding only and are not intended to limit the invention.

Embodiment soil sampler for soil moisture content measurement experiments

As shown in fig. 1 to 3, the present embodiment includes an inner sleeve 1, an outer sleeve 11, a soil-taking mechanism, and a pushing mechanism.

The through holes 5 are formed in the side wall of the inner sleeve 1, the through holes 5 are arranged in a plurality at intervals along the vertical direction of the inner sleeve 1, and the vertical spacing distance can be determined according to the depth of soil taking. The soil taking mechanism is arranged along the radial direction of the inner sleeve 1, and a group of soil taking mechanisms are corresponding to the through holes 5 in each vertical direction.

The outer sleeve 11 is sleeved outside the inner sleeve 1, the outer sleeve 11 is in clearance fit with the inner sleeve 1, and the side wall of the outer sleeve 11 is provided with a strip hole 12 corresponding to the through hole 5, so that the soil sampling blade 2 extends outwards from the strip hole 12 and is inserted into soil. The outer surface of the outer sleeve 11 is provided with a graduated scale 13, the graduated scale 13 is used for displaying the drilling depth, and the bottom end of the outer sleeve 11 is fixedly connected with a conical drill bit 14 convenient for entering the soil.

The soil taking mechanism comprises a soil taking shovel 2, a first spring 3 and a clamping ring 4. Soil sampling shovel 2 is the cylinder, and

soil sampling shovel

2 and 5 clearance fit of through-hole, and soil sampling shovel 2 pegs graft in through-hole 5, makes soil sampling shovel 2 can slide along 5 axis directions of through-hole, and soil sampling shovel 2 is close to the one end of inner skleeve 1 lateral wall and is the open end for soil sampling shovel 2 opening link up with inner skleeve 1's through-hole 5 mutually, and the one end that soil sampling shovel 2 is close to the inner skleeve 1 center is established to the sphere. Namely, one end of the soil sampling shovel 2 far away from the opening end is a spherical surface. The snap ring 4 is fixed on the shovel 2 between sphere and shovel 2 opening, and first spring 3 card is arranged in between 1 inner wall of inner skleeve and

snap ring

4, and 3 one end of first spring and 1 inner wall fixed connection of inner skleeve, the other end and 4 fixed connection of snap ring. When the first spring 3 is in the original length state, the soil sampling shovel 2 is arranged inside the inner sleeve 1.

The pushing mechanism is used for pushing the soil taking shovel 2 of the soil taking mechanism to move outwards and stretch, and comprises a cover plate 6, a push rod 7, an arc-shaped block 8, a handle 9 and a second spring 10. The cover plate 6 covers the top end of the inner sleeve 1 and is used for shielding the opening at the top end of the inner sleeve 1.
