[0004] The above device can only extract one tube of soil sample at a time. When extracting multiple tubes of samples in a certain area, the operator is prone to needing to repeatedly rotate the sampling device, which will cause user fatigue, and repeated operations will waste a lot of time. Although the above device is convenient for extracting soil, the tube body part inserted into the soil will be worn and deformed after long-term use, and it is difficult to replace, thereby affecting the entry of soil.

[0005] A field geological survey device based on the BeiDou system is proposed to solve the above problems. Utility Model Content

[0007] To achieve the above object, the utility model provides the following technical solutions: a field geological survey device based on the Beidou system, comprising a sampling main rod, the sampling main rod comprising a rod body, a hand-held rod is connected through the top of the rod body, and hand-held sleeves are symmetrically installed on both sides of the hand-held rod;

[0008] A multi-point sampling assembly is arranged at the bottom of the rod body, and the multi-point sampling assembly comprises a driving shaft, and a soil sampling assembly is arranged at the bottom end of the driving shaft;

[0009] Among them, the bottom end of the rod body is fixedly connected to the motor compartment, the bottom outer side of the motor compartment is fixedly connected to the mechanical compartment, the interior of the mechanical compartment is provided with a gear plate, the gear plate is meshingly connected with a plurality of force gears, the middle part of the force gear is through-connected with the driving shaft, and the driving shaft passes through the bottom of the mechanical compartment.

[0012] Preferably, a screw sleeve base ring fixedly connected to the mechanical compartment is provided on the side of the driving shaft, and the screw sleeve base ring can be threadedly connected to a protective cap.

[0013] Preferably, the soil taking assembly comprises a fixed block engaged with the driving shaft, the side of the fixed block is engaged with the latch rod, the bottom edge of the fixed block is fixedly connected to a fixed shaft, and the fixed shaft is rotatably connected to the pipe wall.

[0014] Preferably, a first thread is provided in the middle of the outer side of the tube wall, the first thread is threadedly connected to a screw cover, a second thread is provided at the bottom of the outer side of the tube wall, the second thread is threadedly connected to a locking ring, and a depth mark is also provided on the outer side of the tube wall.

[0015] Preferably, a placement bag is fixedly connected to the middle portion of the rod body, and a plurality of placement cavities are provided on the placement bag.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: the field geological survey device based on the Beidou system avoids the judgment of soil geology caused by soil mixing in a single sampling of a single area, and the detachable pipe wall can prevent the pipe wall from being deformed during long-term use or collision, thereby affecting the extraction effect, and can also prevent the rock in a certain area of ​​the ground from preventing the pipe wall from descending, thereby affecting the descent of the pipe wall in other areas. The specific contents are as follows:

[0017] 1. By setting the gear plate and the force gear, the pipe wall can be rotated by multiple force gears during a single sampling, so that multiple points of the target area can be sampled during a single press, avoiding the judgment of the soil geology due to soil mixing in a single area. Since the power for the rotation of the gear plate is provided by the servo motor, the time-consuming and labor-intensive manual rotation can be avoided. The pipe wall can be disassembled and replaced by the spring, connecting rod and latch rod, thereby avoiding deformation of the pipe wall during long-term use or collision, affecting the extraction effect. Unnecessary pipe walls can be disassembled in time according to actual ground conditions to avoid rocks in a certain area of ​​the ground preventing the pipe wall from descending, thereby affecting the sampling of the pipe wall in other areas. The screw base ring and the protective cap can prevent foreign debris from entering the bottom end of the drive shaft after the fixed block is disassembled, causing blockage and affecting the next installation of the fixed block.

[0018] 2. Through the two tube walls rotating with the fixed axis, when it is necessary to extract the soil inside the tube wall, the screw cover and the locking ring can be removed, and then the tube wall can be directly unfolded to facilitate extraction and keep the soil at different depths intact. This avoids the situation where the traditional soil extraction tube needs external objects to push the soil out, which may be insufficient and difficult to extract. It also avoids the situation where the thrust during the push-out causes the soil to be squeezed and mixed, and ultimately leads to misjudgment of the soil geology. BRIEF DESCRIPTION OF THE DRAWINGS
