[0052] like Figure 5 and Figure 6 As shown, the connecting assembly 3 includes a No. 1 connecting cylinder 31 fixedly connected to the inside of the No. 4 mounting cylinder 12, and the top of the No. 1 connecting cylinder 31 is fixedly connected to the connecting plate 13; a No. 1 gear 32 is rotatably provided at the bottom end of the No. 1 connecting cylinder 31, and four sliders 33 are fixedly provided on the inner wall of the No. 1 gear 32, and the four sliders 33 are used to connect with the collecting assembly 4.

[0053] Further, such as Figure 1 , Figure 4 and Figure 6As shown, the collecting assembly 4 includes a hollow drill 41, and four slide grooves 42 are opened on the outer wall of the collecting chamber 1. The hollow drill 41 is located inside the No. 1 gear 32, and the slider 33 is slidably connected with the slide groove 42. When the power assembly 7 is started, it will drive the transmission assembly 5, and the transmission assembly 5 drives the hollow drill 41, and due to the engagement of the slider 33 and the slide groove 42, it rotates.

[0054] Further, such as Figure 1 , Figure 3 and Figure 6 As shown, the discharge component 2 includes a threaded barrel 24 that is threadedly connected to the upper part of the hollow drill 41, the top of the threaded barrel 24 is fixedly connected to the connecting plate 13, and the upper part of the hollow drill 41 is threadedly connected to the threaded barrel 24. When the transmission component 5 drives the hollow drill 41 to rotate, due to the engagement of the slider 33 and the slide groove 42 and the threaded connection between the hollow drill 41 and the threaded barrel 24, the hollow drill 41 rotates and moves downward, so that it drills into the soil to collect the soil. A push rod 21 is provided inside the threaded barrel 24 for sliding movement. The top of the push rod 21 passes through the connecting plate 13 and extends to the top of the connecting plate 13.

The movable block 23 contacts the inner wall of the hollow drill 41. When the collection is completed, the power component 7 is controlled to rotate in the opposite direction to move the hollow drill 41 upward. The soil is retained in the hollow drill 41 because of the blocking component 6.

[0055] Further, such as Figure 6-7 As shown, the blocking assembly 6 includes a blocking bar 62 and a torsion spring. Both sides of the lower interior of the hollow drill 41 are provided with mounting grooves 61. The blocking bar 62 is rotatably connected to the mounting groove 61 through a torsion spring. The blocking bar 62 is in a horizontal state under normal circumstances due to the elastic force of the torsion spring. When the hollow drill 41 drills into the ground, the blocking bar 62 is forced to move upward due to the entry of soil. The blocking bar 62 contacts the soil due to the elastic force of the torsion spring. When the hollow drill 41 moves upward, the soil may still be in a state of connection with the ground. At this time, with the help of the upward power of the hollow drill 41, the blocking bar 62 is cut off by the elastic force of the torsion spring, thereby taking out the soil. Then, the No. 4 mounting tube 12 and the connecting plate 13 are disassembled, the sealing cover 14 is opened, and the outlet of the hollow drill 41 is aligned with the interior of the collecting chamber 1 through the sealing cover 14. Then, the handle 22 is held and pushed forward, so that the movable block 23 pushes the soil inside the hollow drill 41 out and enters the interior of the collecting chamber 1.

[0056] Further, such as Figure 1 and Figure 8As shown, the transmission assembly 5 includes a connecting seat 51 fixedly connected to the collecting chamber 1, the connecting seat 51 is located at the rear end of the No. 1 gear 32, and a No. 2 gear 52 is rotatably provided inside the connecting seat 51.

A mounting hole is provided at the top of the No. 2 gear 52, and a No. 2 mounting cylinder 10 is fixedly connected to the top of the connecting seat 51. The No. 2 mounting cylinder 10 is used to fix the power assembly 7. The No. 1 gear 32 and the No. 2 gear 52 are meshed. When the power assembly 7 is started, the No. 2 gear 52 will rotate, thereby driving the No. 1 gear 32 to make the hollow drill 41 run.

[0057] Further, such as Figure 1 and Figure 8 As shown, the power assembly 7 includes a motor 71, a No. 1 mounting cylinder 72 is fixedly provided on the outer wall below the motor 71, a cross plate 73 is fixedly provided on the output end of the motor 71, the No. 1 mounting cylinder 72 is threadedly connected to the No. 2 mounting cylinder 10, and the cross plate 73 is located inside the No. 1 cross groove 53 through the mounting hole.

[0058] Example 2 further optimizes the freeze-thaw cycle soil sample collection and detection equipment provided in Example 1. Specifically, Figure 1 and Fig. 9 As shown, a test assembly 8 is provided inside the collecting chamber 1, and sliding assemblies 9 are provided on both sides of the test assembly 8. The power assembly 7 is removed and installed on the top of the test assembly 8 so that it has power, and the soil inside the collecting chamber 1 can be subjected to a compression test. A No. 3 mounting tube 11 is fixedly provided on the top of the collecting chamber 1, and the inner wall of the No. 3 mounting tube 11 is provided with threads.

[0059] Further, such as Figure 1 and Fig. 9 As shown, the test assembly 8 includes a connecting hole 84 opened at the top of the collecting chamber 1, the connecting hole 84 is connected to the interior of the collecting chamber 1, a No. 2 connecting tube 83 is fixedly provided at the top of the interior of the collecting chamber 1, a threaded rod 81 is rotatably provided inside the No. 2 connecting tube 83, a No. 2 cross groove 82 is opened at the top of the threaded rod 81, a No. 3 connecting tube 86 is provided on the external thread of the threaded rod 81, a mounting plate 85 is fixedly provided at the bottom end of the No. 3 connecting tube 86, a pressure sensor is provided at the bottom end of the mounting plate 85, a displacement sensor is provided inside the collecting chamber 1, and the pressure sensor and the displacement sensor are connected to the control panel 15.

When the power assembly 7 is installed inside the No. 3 mounting cylinder 11, the motor 71 is started. Since the cross plate 73 is located inside the No. 2 cross groove 82, it drives the threaded rod 81 to rotate, so that the No. 3 connecting cylinder 86 cooperates with the sliding assembly 9 to slowly descend until it contacts the soil to test its compressive strength. The pressure sensor and the displacement sensor transmit data to the control panel 15, and the soil is crushed while the compressive strength test is being performed, so that the components inside the soil can be extracted for chemical testing later.

[0061] The use process of the freeze-thaw cycle soil sample collection and detection device provided by the utility model is as follows:

[0062] When it is necessary to use the hollow drill 41 to collect samples, the motor 71 is started to drive the second gear 52 to rotate, thereby driving the first gear 32 to make the hollow drill 41 run. The hollow drill 41 moves downward while rotating to drill into the soil. When the hollow drill 41 drills into the ground and reaches a certain depth, the motor 71 is controlled to rotate in the opposite direction, and the sample will not fall off through the blocking component 6. Then, the fourth mounting tube 12 and the connecting plate 13 are disassembled, and the plug plate 18 is separated from the plug hole by shifting the shifting blocks 19 on both sides of the connecting plate 13. At this time, the connecting component 3 and the collecting component 4 are rotated backward through the rotation connection between the fourth mounting tube 12 and the collecting chamber 1, and then the handle 22 is held and pushed forward, so that the movable block 23 pushes out the sample inside the hollow drill 41, and the pushed soil is placed into the collecting chamber 1 through the sealing cover 14. The environment inside the collecting chamber 1 is adjusted through the control panel 15. When testing is required, the power component 7 is removed and installed on the top of the test component 8, and the motor 71 can be started to perform a pressure test on the soil inside the collecting chamber 1.
