[0092] The working principle and beneficial effects of this invention are as follows:

[0093] In this invention, during the operation of the soil drilling rig, after the soil sampling tube has collected soil, the arc-shaped clamping bar in the arc-shaped clamping arm mechanism clamps one half of the soil sampling tube. The arc-shaped clamping arm mechanism drives the soil sampling tube to reverse, separating the soil sampling tube into two parts. The half of the soil sampling tube clamped by the arc-shaped clamping arm has a built-in telescopic baffle. While achieving separation, the telescopic baffle pops out to prevent the soil sampled in the soil sampling tube from falling to the ground. At the same time, the soil sampling coordination mechanism starts to operate and cooperates with the half of the soil sampling tube clamped by the arc-shaped clamping bar. The soil sampling coordination mechanism transfers the sampled soil in the soil sampling tube to the connecting sleeve. The soil sampling coordination mechanism separates the sampled soil and puts the separated soil into the soil screening mechanism for screening. This reduces manual operation, reduces working steps, speeds up soil sampling and testing, and makes it faster to complete the soil sampling work. Attached Figure Description

When the connecting strip 44 slides to the lowering position in the first limiting seat 43, the first electric telescopic block 47 and the second electric telescopic block 48 move, causing the fixing rod 49 to engage with the round hole on the isolation plate 39.

[0198] It also includes a soil screening mechanism, which includes,

[0199] The partition box 50 is mounted on the supporting base frame 2.

[0200] A screening assembly is mounted on the separator 50.

[0201] The screening component includes,

[0202] There are two sixth support bases 65, which are fixedly connected to the partition box 50.

[0203] A circular support base 62 is mounted on the sixth support base 65.

[0204] A vibrating screen barrel 51 is fixedly connected to the circular support base 62.

[0205] Screen 52, the screen 52 is installed on the vibrating screen barrel 51.

[0206] Vibrating block 53, which is installed on the vibrating screen barrel 51.

[0207] An electric rotating shaft 54 ​​is connected to the circular support base 62 and the partition box 50.

[0208] A soil storage assembly is installed on the partition box 50.

[0209] The soil storage component includes,

[0210] The ninth slide rail 19, of which several are provided, is mounted on the partition box 50.

[0211] A plurality of ninth electric slide blocks 57 are provided, and the plurality of ninth electric slide blocks 57 slide on the ninth slide rail 19.

[0212] The four storage bins 56 are mounted on the ninth electric slide block 57.

[0213] In this embodiment, the soil screening mechanism is installed on the support base 2. The connecting sleeve 38 cooperates with the semi-circular fitting pipe 64. The second electric telescopic block 48 pushes the isolation plate 39 inside the connecting sleeve 38, and the soil sampled by the connecting sleeve 38 falls onto the screen 52 in the vibrating screen barrel 51. The vibrating screen barrel 51 is equipped with a vibrating block 53, which drives it to vibrate. An electric rotating shaft 54 ​​is installed on the circular support 62 installed on the sixth support 65. The electric rotating shaft 54 ​​connects the circular support 62 and the separator box 50. After the soil screening is completed, the gravel and root-like materials remaining on the screen 52 are poured into the separator box 50 through the electric rotating shaft 54. The separator 50 has a hollowed-out bottom, allowing residual gravel and root-like materials on the screen 52 to fall to the ground. The sieved soil falls into the storage bin 56 below. The storage bin 56 is brought to the other side of the separator 50 by the ninth electric slide 57. The three first electric telescopic blocks 47 sequentially pull out the three partition plates 39, and sequentially put the sampled soil from the connecting sleeve 38 into the screen. The above steps are repeated to sieve the sampled soil in sequence. After the sampled soil is sieved, the soil detector installed on the support base 2 probes into the storage bin 56 through its probe to sequentially test the soil in different storage bins 56.

[0214] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
