A transparent tempered glass trough 5 is fixedly installed on the top of the connecting plate 4. In order to guide the transparent tempered glass trough 5 and make the transparent tempered glass trough 5 move more stably, two guide holes are opened on the top of the U-shaped bottom plate 1, and guide rods 12 are slidably installed in the two guide holes. The tops of the two guide rods 12 are fixedly installed with mounting blocks 11, and the two mounting blocks 11 are both fixedly installed with the transparent The tempered glass trough body 5 is fixedly connected, and soil is contained in the transparent tempered glass trough body 5. The transparent tempered glass trough body 5 and the soil form a soil trough test bench, and a planting experiment on crops is carried out through the soil trough test bench. Due to the transparent state of the transparent tempered glass trough body 5, the staff can observe the overall structural stratification of the soil from the surface to the deep layer through the transparent tempered glass trough body 5, such as the thickness of each soil layer, the color change and the transition state between different soil layers, and then the structural differences of soil layers at different depths due to the action of fertilizers can be observed.

[0027] In order to increase the service life of the rotating screw 7, lubricating oil tanks 13 are fixedly installed at the bottom of the two movable columns 10, and two lubricating oil application rollers 14 are rotatably installed in the two lubricating oil tanks 13. The four lubricating oil application rollers 14 are rotatably connected to the corresponding movable columns 10, and the four lubricating oil application rollers 14 are respectively in contact with the two rotating screws 7. The rotation of the rotating screw 7 drives the lubricating oil application rollers 14 to rotate through friction, and then the lubricating oil is continuously applied to the rotating screw 7, thereby reducing the wear of the rotating screw 7.

[0028] A plurality of bayonet holes 9 are provided at the bottom of the load-bearing plate 2, winding rods 17 are provided on both sides of the two movable frame plates 3, and the four winding rods 17 are respectively provided with fixed plates 15 which are rotatably sleeved, and the four fixed plates 15 are respectively fixedly connected to the two movable frame plates 3, and the four winding rods 17 are respectively provided with semicircular gears 21 which are fixedly sleeved, and the four semicircular gears 21 are all meshed with the bayonet holes 9, and the tops of the two lubricating oil tanks 13 are respectively provided with sealing cover plates 22, and in order to make the sealing cover plates 22 more tightly connected with the lubricating oil application roller 14 and the movable column 10, thereby reducing the evaporation of the lubricating oil, the sealing cover plates 22 are made of rubber material. Since rubber has a certain flexibility, it can be in closer contact with the lubricating oil application roller 14 and the movable column 10, and the two sealing cover plates 22 are slidingly and sealingly connected to the corresponding lubricating oil application roller 14 and the movable column 10, and four pull ropes 18 are fixedly installed on the top of the two sealing cover plates 22, and the top ends of the eight pull ropes 18 are fixedly connected to the corresponding winding rods 17, and two cross plates 20 are fixedly installed on the outer walls of both sides of the two lubricating oil tanks 13, and elastic ropes 19 are fixedly installed on the top ends of the four cross plates 20, and the four elastic ropes 19 are fixedly connected to the two sealing cover plates 22.

[0029] In order to drive the semicircular gear 21 to return to its original initial state of engagement with the bayonet 9 when the semicircular gear 21 rotates for the first half of the cycle and no longer engages with the bayonet 9, thereby causing the sealing cover plate 22 to continuously move up and down and separate from the lubricating oil application roller 14, two torsion springs 16 are movably sleeved on the four winding rods 17. In order to increase the service life of the torsion springs 16, the surface of the torsion springs 16 is tin-plated, and one end of the eight torsion springs 16 is fixedly connected to the corresponding semicircular gears 21, and the other ends of the eight torsion springs 16 are fixedly connected to the corresponding fixing plates 15.

[0030] The working principle of the soil structure change monitoring soil trough test bench provided by the present invention is as follows: in the initial state, the lubricating oil tank 13 is filled with lubricating oil, the torsion spring 16 is in a free state, the elastic rope 19 is in a stretched state, the lubricating oil coating roller 14 is in contact with the rotating screw 7, and the sealing cover plate 22 blocks the opening of the lubricating oil tank 13 to reduce the evaporation of the lubricating oil. The soil trough test bench is composed of a transparent tempered glass trough body 5 and soil, and a planting experiment is carried out on crops through the soil trough test bench. Due to the transparent state of the transparent tempered glass trough body 5, the staff can observe the entire soil from the surface to the deep layer through the transparent tempered glass trough body 5. The structural stratification, such as the thickness of each soil layer, the color change and the transition state between different soil layers, can be observed, and the structural differences of soil layers at different depths due to the action of fertilizers can be observed. When researchers with taller stature need to use the device, the dual-axis motor 6 is started, and the rotation of the dual-axis motor 6 drives the rotating screw 7 to rotate, and the rotation of the rotating screw 7 drives the moving column 10 to move, and the movement of the moving column 10 drives the two moving frame plates 3 to approach each other, and the two moving frame plates 3 approach each other to drive the tops of the four hinged plates 8 to move upward, thereby moving the transparent tempered glass trough 5 upward to a suitable height, so that the staff of this height can When using the device, there is no need to bend over, which reduces the work intensity. At the same time, the movement of the movable frame plate 3 drives the fixed plate 15 to move, and the movement of the fixed plate 15 drives the semicircular gear 21 to rotate along the bayonet 9 for the first half cycle. The rotation of the semicircular gear 21 drives the winding rod 17 to rotate, and the rotation of the winding rod 17 reels the pull rope 18, thereby causing the sealing cover plate 22 to move upward and separate from the lubricating oil application roller 14, which will not affect the rotation of the lubricating oil application roller 14. At the same time, the rotation of the semicircular gear 21 causes the torsion spring 16 to change from a free state to a stressed state. When the semicircular gear 21 rotates the first half cycle and is no longer engaged with the bayonet 9, the torsion spring 16 is 16 is to be restored to its original free state, driving the semicircular gear 21 to rotate in the opposite direction, so that the semicircular gear 21 returns to its original initial state of meshing with the bayonet 9. The semicircular gear 21 rotates in the opposite direction to release the pull rope 18 through the winding rod 17, thereby restoring the sealing cover plate 22 to its original initial state. In this way, the sealing cover plate 22 is continuously moved up and down and separated from the lubricating oil application roller 14 by rotating the rotating screw 7. At the same time, the rotating screw 7 rotates to drive the lubricating oil application roller 14 to rotate through friction, thereby continuously applying lubricating oil to the rotating screw 7, reducing the wear of the rotating screw 7 and increasing its service life.
