[0002] Soil erosion is a natural phenomenon that refers to the continuous wear and tear of the Earth's surface by external forces such as wind, water, and ice melt. This damage, movement, and accumulation of surface soil, parent material, and rock, as well as water loss, results in both soil erosion and water loss. In forestry, vegetation can mitigate the impact of rain on the underlying soil and prevent soil from being washed away by rain, but some soil erosion still occurs. Therefore, controlling soil erosion on slopes is particularly important, and the sand content of slope soil is a key parameter for assessing soil erosion.

[0003] A known Chinese patent application (publication number: CN211741271U) discloses a water and soil erosion simulation device that is easily adjustable. The device adjusts the slope of a soil storage box by adjusting the coordination of a screw, a slider, a chute, a hinge shaft, a threaded barrel, a fastening nut, and other structures.

[0004] Although the slope of the soil storage box can be adjusted by rotating the first adjusting screw, the first adjusting screw is arranged at the bottom. When adjusting, the operating space of the hand is small, and fast and convenient adjustment cannot be achieved. Therefore, a soil erosion simulation device that is easy to adjust is proposed.

DETAILED DESCRIPTION

[0024] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0025] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 4 As shown, the embodiment of the present invention provides a soil and water loss simulation device that is easy to adjust, including a simulation component 101, the simulation component 101 includes a simulation box 11, a soil storage plate 12, a rotating shaft 13, a support shaft 15, two sliding seats 16, two limiting grooves 17, a threaded rod 18, two guide rods 19, a lifting plate 21 and a fixing plate 22;

[0027] The two ends of the rotating shaft 13 are symmetrically connected to the front of the inner wall of the simulation box 11, the front of the lower surface of the soil storage plate 12 is fixedly connected to the outer wall of the rotating shaft 13, and the support shaft 15 is fixedly connected to the adjacent surfaces of the two sliding seats 16. The two limiting grooves 17 are symmetrically opened on both sides of the simulation box 11, the two sliding seats 16 are symmetrically fixedly connected to the front surface of the lifting plate 21, and the fixed plate 22 is fixedly connected to the rear surface of the simulation box 11. The bottom end of the threaded rod 18 is rotatably connected to the upper surface of the lifting plate 21, and the bottom ends of the two guide rods 19 are symmetrically fixedly connected to the upper surface of the lifting plate 21. The lower surface of the soil storage plate 12 is attached to the outer wall of the support shaft 15. The soil storage plate 12 is used to place materials such as sand, gravel and soil to simulate the slope. The diameter of the support shaft 15 is the same as the diameter of the rotating shaft 13. In the initial state, the sliding seat 16 is located at the bottom of the limiting groove 17. At this time, the support shaft 15 and the rotating shaft 13 are on the same horizontal plane.

[0028] In one embodiment, the soil storage plate 12 is located inside the simulation box 11 . The front surface of the simulation box 11 is provided with an opening, the size of the opening is larger than the size of the soil storage plate 12 , and the top of the simulation box 11 is also an opening.

[0029] In one embodiment, the threaded rod 18 is threadedly connected to the interior of the fixed plate 22, the guide rod 19 is slidably connected to the interior of the fixed plate 22, and the sliding seat 16 is slidably connected to the inner side wall of the limiting groove 17;

[0030] When adjusting the angle of the simulated slope, the threaded rod 18 is rotated. Since the threaded rod 18 is threadedly connected to the fixed plate 22, the threaded rod 18 can drive the lifting plate 21 to move upward, and the lifting plate 21 drives the sliding seat 16. The sliding seat 16 drives the support shaft 15. The support shaft 15 moves upward. Since the support shaft 15 is in contact with the lower surface of the soil storage plate 12, the soil storage plate 12 rotates around the rotating shaft 13, and the rear part of the soil storage plate 12 is lifted upward. At this time, the adjustment of the simulated slope angle is achieved.

[0031] In one embodiment, a scale line 14 is provided on one side of the simulation box 11 , and the simulation box 11 is made of transparent acrylic material. Thus, when adjusting the angle of the soil retaining plate 12 , the current simulation angle can be intuitively seen by comparing the scale line 14 .

[0032] In one embodiment, a water sprinkling assembly 301 is installed inside the simulation box 11 , and the water sprinkling assembly 301 includes a water tank 31 and a through hole 32 ;

[0033] The water tank 31 is located inside the simulation box 11, and through holes 32 are equidistantly formed on the inner bottom wall of the water tank 31. The water tank 31 is located above the soil retention plate 12. By adding water to the water tank 31, the water flows out of the through holes 32 and then drips onto the simulated slope of the soil retention plate 12, thereby simulating the process of soil erosion.

[0034] During the simulation of soil erosion, a collecting bucket may be provided at the front of the simulation box 11 to collect the water-soil mixture.

[0035] In one embodiment, two handles 33 are symmetrically fixedly connected to both sides of the water tank 31. The handles 33 are attached to the upper surface of the simulation box 11. The position of the water tank 31 can be limited by the handles 33, and the water tank 31 can be easily taken out of the simulation box 11 through the handles 33.

[0036] When the present invention is working: the simulation box 11 is placed on a horizontal surface, and then the sand, gravel, soil and other materials for simulating the slope are placed in the soil storage plate 12, and the threaded rod 18 is rotated. The threaded rod 18 drives the lifting plate 21 to move upward, and the lifting plate 21 drives the sliding seat 16. The sliding seat 16 drives the support shaft 15, and the support shaft 15 moves upward. The soil storage plate 12 rotates with the rotating shaft 13 as the center, and the rear part of the soil storage plate 12 is lifted upward. By referring to the scale line 14, the current simulation angle can be intuitively seen. At this time, the adjustment of the simulated slope angle is realized, and then the water tank 31 is placed into the simulation box 11 from above, and clean water is injected into the water tank 31 to carry out a soil and water loss simulation experiment. The water source in the simulation box 11 flows out from the through hole 32, and then drips onto the simulated slope on the soil storage plate 12. The water flow scours the simulated slope, thereby simulating soil and water loss on the slope.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
