The sampling component 61 includes: a fixing plate 611, symmetrically fixedly installed at the bottom of the support frame 4; and a motor 612, fixedly installed on the outside of the fixing plate 611. A guide rod 614 is fixedly installed between the fixing plates 611. A threaded rod 613 is provided at the output end of the motor 612, and the other end of the threaded rod 613 movably passes through the outside of the fixing plate 611 and the fixing plate 611. The inner side extends to the inner side of another fixed plate 611 and is rotatably connected to the fixed plate 611 via a bearing. The outer wall of the threaded rod 613 is threadedly connected to a moving block 615. The moving block 615 is slidably sleeved with the guide rod 614.

It is rotatably connected to the storage outer cylinder 6111 via a bearing. A spiral blade 6113 is fixedly sleeved on the outer wall of the rotating shaft 6112.

[0030] Furthermore, in this embodiment, by starting motor 612, motor 612 drives threaded rod 613 to rotate. Since moving block 615 is threadedly connected to threaded rod 613 and slidably sleeved with guide rod 614, moving block 615 will move forward along guide rod 614. When moving block 615 drives cylinder 616 and outer cylinder 6111 to the notch of bottom plate 1, cylinder 616 is started. The telescopic end of cylinder 616 extends, pushing connecting plate 617 and outer cylinder 6111 to further contact and insert into the soil. Motor 619 is started, and motor 619 drives rotating shaft 6112 and spiral blade 6113 to rotate. Spiral blade 6113 spirals soil into outer cylinder 6111. After sampling is completed, motor 619 is turned off, cylinder 616 is started to retract, and outer cylinder 6111 is pulled out of the soil.

[0031] Example 2: Based on Example 1, a preferred embodiment of the soil sampler for water conservancy projects provided by this utility model is as follows: Figures 1-4As shown: The storage component 62 includes: a storage box 621, fixedly fitted inside the mounting opening; a fixed vertical plate 629, symmetrically fixedly installed on the back of the base plate 1; a motor 6211, fixedly installed on the outside of the fixed vertical plate 629; connection ports are respectively opened on both sides of the storage box 621, and a snap-fit ​​opening is opened on the back of the storage box 621; a connecting pipe 622 is connected to the top of the storage box 621; slide rods 623 are symmetrically fixedly installed on both sides of the inner wall of the storage box 621; a sealing plate 624 is slidably connected to the outer wall of slide rod 623; the sealing plate 624 is slidably connected to the storage box 621 through the connection port; slide rods 625 are symmetrically fixedly installed on the other two sides of the inner wall of the storage box 621; a storage drawer 626 is slidably connected to the outer wall of slide rod 625; the storage drawer 626 is slidably connected to the storage box 621 through the snap-fit ​​opening; the storage drawer 62... A locking plate 627 is fixedly installed on the outer side of 6. The locking plate 627 is locked to the storage box 621 through the locking port. A handle 628 is fixedly installed on the other side of the locking plate 627. A bidirectional threaded rod 6212 is provided at the output end of the motor 6211. The other end of the bidirectional threaded rod 6212 moves through the outer side of the fixed vertical plate 629, the inner side of the fixed vertical plate 629 and extends to the inner side of another fixed vertical plate 629. It is rotatably connected to the fixed vertical plate 629 through a bearing. A movable plate 6216 is symmetrically threaded to the outer wall of the fixed vertical plate 629. A connecting block 6213 is fixedly installed on the outer side of the sealing plate 624. A connecting vertical plate 6214 is fixedly installed on the other side of the connecting block 6213. A connecting horizontal plate 6215 is fixedly installed on the inner side of the connecting vertical plate 6214. One side of the connecting horizontal plate 6215 is fixedly connected to the movable plate 6216.

[0032] Furthermore, in this embodiment, by starting the motor 6211, the motor 6211 drives the bidirectional threaded rod 6212 to rotate. Since the moving plate 6216 is threadedly connected to the bidirectional threaded rod 6212, and the connecting horizontal plate 6215 is connected to the sealing plate 624 through the connecting vertical plate 6214 and the connecting block 6213, the rotation of the bidirectional threaded rod 6212 will cause the moving plate 6216 and the sealing plate 624 to move to both sides, opening the obstruction to the connecting pipe 622, and pouring the soil in the outer cylinder 6111 into the storage box 621 through the connecting pipe 622. When it is necessary to remove the soil sample from the storage box 621, it is pulled outwards. Pull the handle 628. The handle 628 will cause the locking plate 627 and the storage drawer 626 locked on the storage box 621 to slide outward. Slide the storage drawer 626 until the locking opening is fully exposed, and the soil sample can be easily taken out. After taking out the soil sample, push the storage drawer 626 back into the storage box 621, and ensure that the locking plate 627 is locked tightly with the storage box 621. Start the motor 6211 in reverse, so that the bidirectional threaded rod 6212 rotates, which drives the moving plate 6216 and the sealing plate 624 to move towards the center. Close the connection port, turn off all motors and cylinders, and move the sampler to a safe position, ready for the next use.

[0033] In use, the sampler is moved to the desired sampling position using push rod 5 and caster wheel 3. Motor 612 is then started, driving threaded rod 613 to rotate. Since moving block 615 is threadedly connected to threaded rod 613 and slidably fitted with guide rod 614, moving block 615 moves forward along guide rod 614. When moving block 615 moves cylinder 616 and outer storage cylinder 6111 to the notch in base plate 1, cylinder 616 is activated, extending its telescopic end and pushing connecting plate 617 and outer storage cylinder 611. 1. Further contact and insertion into the soil, start motor 2 619. Motor 2 619 drives the rotating shaft 6112 and the spiral blade 6113 to rotate. The spiral blade 6113 spirals the soil into the outer collection cylinder 6111. After sampling, turn off motor 2 619, start cylinder 616 to retract it, and pull the outer collection cylinder 6111 out of the soil. Move the sampler to a suitable position using push rod 5, preparing to transfer the soil to the collection box 621. Start motor 6211. Motor 6211 drives the bidirectional threaded rod 6212 to rotate. Due to the moving plate 62 16 is threadedly connected to the bidirectional threaded rod 6212, and the connecting horizontal plate 6215 is connected to the sealing plate 624 through the connecting vertical plate 6214 and the connecting block 6213. Therefore, the rotation of the bidirectional threaded rod 6212 will drive the moving plate 6216 and the sealing plate 624 to move to both sides, opening the obstruction to the connecting pipe 622, and pouring the soil in the outer cylinder 6111 into the storage box 621 through the connecting pipe 622. When it is necessary to take out the soil sample in the storage box 621, pull the handle 628 outward. The handle 628 drives the locking plate 627 and the locking mechanism. Slide the storage drawer 626 on the storage box 621 outwards until the locking opening is fully exposed, and the soil sample can be easily removed. After removing the soil sample, push the storage drawer 626 back into the storage box 621, and ensure that the locking plate 627 is tightly locked with the storage box 621. Start the motor 6211 in reverse to rotate the bidirectional threaded rod 6212, which will drive the moving plate 6216 and the sealing plate 624 to move towards the center. Close the connection port, turn off all motors and cylinders, and move the sampler to a safe position for the next use.
