The bottom end of the outer wall of the water storage box 21 is elastically connected to the contact block 22 through a limit spring 23. One end of the limit spring 23 is fixedly connected to the top of the outer wall of the contact block 22, and the other end of the limit spring 23 is fixedly connected to the bottom end of the outer wall of the water storage box 21. The function of the limit spring 23 is to automatically reset the position of the contact block 22 after being squeezed and moved. The top of the outer wall of the contact block 22 is fixedly connected to a moving plate 24, and the moving plate 24 is slidably connected to the inner wall of the water storage box 21. The moving plate 24 moves up and down inside the water storage box 21 through the moving plate 24, so that the other end of the moving plate 24 closes and opens the through hole of the water storage box 21 corresponding to the water outlet 25, thereby realizing automatic water discharge. The top of the outer wall of the contact arm 6 contacts the bottom end of the outer wall of the contact block 22, and the two are in contact, so that the contact block 22 is squeezed through the contact arm 6. The outer side wall of the water storage box 21 is elastically connected with a triangular block 28 through a return spring 27. One end of the return spring 27 is fixedly connected to the inner wall of the outer side of the water storage box 21, and the other end of the return spring 27 is fixedly connected to the top of the outer wall of the triangular block 28.

The inner wall of the bottom end of the water storage box 21 is slidably connected with an adjusting plate 26. The adjusting plate 26 is moved on the inner wall of the water storage box 21 by the adjusting plate 26, so as to block the flow of water discharged outward from the water outlet 25, so as to adjust the water output of the water outlet 25. The bottom end of the outer wall of the water storage box 21 is provided with a water outlet 25.

[0036] Reference Figure 4-Figure 6 The limit assembly 3 includes a handle 31, the inner wall of the handle 31 is elastically connected to the plug block 33 through a connecting spring 32, one end of the connecting spring 32 is fixedly connected to the inner wall of the handle 31, and the other end of the connecting spring 32 is fixedly connected to the outer wall of the plug block 33.

[0037] Working principle: When testing the water permeability of soil, multiple groups of soil sample barrels 5 can be taken out from the inside of the turntable 4 to inject soil into it and insert them into the corresponding empty slots of the turntable 4. At this time, the soil can be flushed according to different water flows to test the water permeability. The adjustment plate 26 can be directly pushed to move on the inner wall of the water storage box 21, so as to adjust and block the corresponding through holes at the bottom of the water storage box 21. When the adjustment plate 26 is directly pushed, the groove on its surface will squeeze the inclined surface of the triangular block 28, so as to move the triangular block 28 upward on the outside of the water storage box 21 and allow the reset spring 27 to be elastically compressed until the next group of grooves are reached, so that it is elastically acted upon by the reset spring 27 and restored to its initial position to fix the moved position of the adjustment plate 26.

[0038] At this time, the handle 31 can be grasped to press the plug block 33 to move on its inner wall, and the connecting spring 32 can be elastically compressed, so that the turntable 4 can be rotated to allow the contact arm 6 of the outer wall of the soil sample barrel 5 on its surface to squeeze the contact block 22 at the bottom of the water storage box 21, and the limit spring 23 can be elastically compressed. At this time, the contact block 22 will drive the movable plate 24 to move upward on the inner wall of the water storage box 21 during the squeezing process, so that the other end of the contact block 22 can be separated from the through hole of the water outlet 25 corresponding to the water storage box 21 to open it, so that the water inside the water storage box 21 will spray outward along the water outlet 25, thereby watering the inside of the soil sample barrel 5, so that the soil permeability inside it can be observed based on the transparent soil sample barrel 5.
