Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for an adjustable soil remediation sample collection device: it includes a sampling cylinder 1, a handle 2 connected to the top of the sampling cylinder 1, a storage box 3 provided at the connection between the sampling cylinder 1 and the handle 2, the storage box 3 includes a box body 31, a top cover 306 provided at the top of the box body 31, a sieve plate 32 connected to the inner side wall of the box body 31, two connecting blocks 33 provided on both sides of the sieve plate 32, and connecting grooves 34 opened at the corresponding positions of the inner side wall of the box body 31 and the sliding path of the connecting blocks 33.

[0023] The sampling tube 1 has a sampling cavity 11 at its bottom end and a connector 12 at its top end. The outer surface of the connector 12 has four discharge slots 13 arranged in a ring shape. The bottom surface of the box body 31 is connected to a support block 301. An adjusting column 302 is connected through the surface of the support block 301. One end of the adjusting column 302 is connected to a fixing pin 304. A connecting spring 303 is connected to the outer surface of the adjusting column 302 and one side of the support block 301. Two sliders 305 are connected to the inner wall of the box body 31. The outer surface of the connector 12 and the corresponding sliding path of the sliders 305 are provided with matching grooves 14. The outer surface of the connector 12 and the corresponding fixing pins 304 are provided with matching fixing holes 15. It should be noted that the cooperation of the adjusting column 302, the fixing pins 304, the sliders 305 and the connector 12 enables the box body 31 to be quickly assembled and disassembled, thereby facilitating the rapid collection of samples and improving the sampling efficiency.

[0024] The inner wall of the connecting groove 34 is connected to a sliding column 35. The surface of the connecting block 33 is provided with a through hole corresponding to the sliding column 35. The outer surface of the sieve plate 32 is connected to a spring 38. The outer surface of the sliding column 35 and the bottom surface of the connecting block 33 are connected to a return spring 36. The bottom surface of the box body 31 is provided with a discharge groove. The outer surface of the box body 31 is provided with an adjustment groove 39 corresponding to the sliding path of the spring 38. One end face of the box body 31 is provided with a feeding groove 37.

[0025] The working principle of this utility model is as follows: When sampling the soil layer, the soil sample enters the four feeding troughs 37 simultaneously through the four sampling chambers 11 and the discharge trough 13, falls into the four boxes 31, and is stored on the surface of the sieve plate 32. By hand, the spring piece 38 is repeatedly pressed along the adjustment groove 39, which drives the sieve plate 32 and the connecting block 33 to slide along the connecting groove 34, squeezing the reset spring 36, so that the sieve plate 32 resets again. This process is repeated to quickly separate the soil and larger impurities in the soil sample, thus completing the sample screening.

[0026] Pull the adjusting column 302 outward along the inner wall of the support block 301, stretch the connecting spring 303, so that the fixing pin 304 at one end of the adjusting column 302 separates from the inner wall of the fixing hole 15, and then slide the box body 31 out along the groove 14 on the surface of the connector 12, so that multiple soil samples can be collected and stored.
