The sampling drive assembly 500 is used to drive the rotating sleeve portion 230 to rotate intermittently, and when the rotating sleeve portion 230 is in a rotating state, When the rotating sleeve portion 230 is in the stopped state, the sampling drive assembly 500 drives the rotating scraper assembly 700 to rotate alternately forward and reversely around the center of the sampling rod 200, and the rotating scraper assembly 700 can act on the blocking strips 800 and make the blocking strips 800 move on both sides of the lower drop port 440; the rotating scraper assembly 700 can also act on the dividing and storing assembly 600 and drive the dividing and storing assembly 600 to rotate during the rotation process; the upper extension frame 310 is provided with a screw sleeve portion 320 at the end away from the main frame 100, the top of the sampling rod 200 passes through the screw sleeve portion 320 and the inside of the screw sleeve portion 320 is spirally matched with the spiral portion 220.

[0029] In the embodiment of the present invention, the geological survey staff can lift the entire sampler by the handle 150 and carry it around, and place the entire sampler at the sampling position with the base plate 110 and the bottom of the collecting tray assembly 400 in contact with the ground; the center of the collecting tray assembly 400 is located relative to the sampling position, and the sampling drive assembly 500 starts to work and drives the rotating sleeve portion 230 to rotate intermittently; when the rotating sleeve portion 230 is in a rotating state, the rotating sleeve portion 230 drives the sampling rod 200 to rotate, and due to the spiral cooperation between the spiral portion 220 and the spiral sleeve portion 320, the sampling rod 200 moves downward in the rotating state, and the sampling spiral blade 210 gradually passes through the upper barrel portion 460. The sampling spiral blade 210 is rotated into the sampling layer, and the sampling spiral blade 210 transports the sample in the sampling layer to the upper surface of the upper collecting plate 410 through the upper barrel body 460.

The component 700 pushes the sample to the drop port 440 and drops it into one of the bins in the material distribution storage component 600; the rotary scraper component 700 rotates and moves to the initial position; the sampling drive component 500 disengages from the top of the rotary scraper component 700 and acts on the rotating sleeve part 230 again, so that the sampling rod 200 continues to rotate downward into the sampling layer, and the sample at the bottom layer is transported to the surface of the upper collecting plate 410; in this way, the reciprocating operation can make the sample in the sampling layer be transported to the surface of the upper collecting plate 410 at a staged depth, and the rotary scraper component 700 scrapes and transports them to multiple bins of the material distribution storage component 600 for storage, thereby realizing the sampling of samples at different depths.

[0039] The above embodiment provides a portable geological survey sampling machine, wherein during sampling, the sampling motor 510 works and drives the second transmission rod shaft 530 to rotate, and the second transmission rod shaft 530 intermittently drives the rotating sleeve portion 230 and the first transmission rod shaft 520 to rotate through the alternating meshing of the semicircular arc gear 540 with the sampling gear 240 and the outer transmission gear 550. The rotation time periods of the rotating sleeve portion 230 and the first transmission rod shaft 520 are staggered, so that when the sampling rod 200 is rotated into the sampling layer, the first transmission rod shaft 520 stops rotating, and when the sampling rod 200 stops rotating for sampling, the first transmission rod shaft 520 rotates, and when the first transmission rod shaft 520 rotates The incomplete gear part 580 meshes with the two inner racks 570 alternately to make the movable frame 560 reciprocate at the bottom of the support frame 300. The movable frame 560 meshes with the outer rack 590 and the outer gear ring 730 to make the rotating ring 720 reciprocate, so that the scraping radial plate 710 reciprocates around the center line of the sampling rod 200. When the arc-shaped rack 760 passes through the switching transmission component 900, the arc-shaped rack 760 meshes with the driven part 920 and drives the driven part 920 to rotate, so that the vertical shaft 910 and the lower gear 930 rotate, and the lower gear 930 meshes with the outer connecting ring 650 to make the rotating disk 610 and the upper connecting ring 64 0 rotates, so that one of the collecting troughs 630 rotates to the lower side of the drop port 440. When the rotating scraper assembly 700 passes through the switching transmission component 900 and pushes away the blocking strip 800, the sample can fall from the drop port 440 to the inside of the collecting trough 630. During the process of the rotating scraper assembly 700 rotating to the initial position, the rotating scraper assembly 700 acts on the driven part 920 to rotate it, but due to the existence of the one-way ratchet, the vertical shaft 910 and the lower gear 930 do not rotate, so the material distribution storage assembly 600 is in a stationary state, so that when the rotating scraper assembly 700 scrapes and delivers the sample next time, it acts on the driven part 920 to make the other Each collecting trough 630 rotates to the lower side of the drop port 440, so that the sample falls from the drop port 440 to the inner side of one of the collecting troughs 630 and is stored. After the sample on the upper collecting plate 410 falls completely, the sampling drive assembly 500 acts on the rotating scraper assembly 700 and causes the rotating scraper assembly 700 to rotate. The rotating rotating scraper assembly 700 no longer acts on the outer connecting ring 650 by switching the transmission component 900, so that the rotating plate 610 and the collecting trough 630 maintain a stable state, and the rotating scraper assembly 700 rotates to the initial position; the sampling rod 200 rotates again and screws downward into the sampling layer. In this way, the samples can be sampled in stages and stored automatically.
