Description

Technical Field

[0001] This utility model relates to the technical field of soil and water conservation devices, specifically a bentonite multi-layer permeable soil and water conservation device. Background Technology

[0002] Bentonite, also known as bentonite rock, soapstone, or bentonite stone, is a non-metallic mineral with montmorillonite as its main mineral component. Many of the properties of bentonite are determined by montmorillonite. Montmorillonite can be various colors, such as yellow-green, yellowish-white, gray, and white. It can be found in dense lumps or loose, earthy forms. It feels slippery when rubbed between the fingers, and small pieces expand several times in volume when water is added.

[0003] Considering that bentonite will collide when it comes into contact with water, giving it good water absorption, bentonite is often used as a moisture-retaining material. In the process of water and soil moisture retention, it is necessary to assist in moisture retention of water in different strata. Therefore, some bentonite water and soil moisture retention devices with special structures and functions can be applied.

[0004] Generally, traditional water and soil moisture retention devices involve mixing bentonite with soil and then laying it on the ground that needs moisture retention. Sometimes, a covering net is laid afterward for protection to reduce bentonite loss. However, laying bentonite on the surface results in low moisture penetration, meaning the moisture retention effect is only good for the surface depth and has limited ability to retain moisture at the bottom. The moisture on the surface dries easily, reducing the overall moisture retention effect. Furthermore, the covering net can easily cause bentonite to be lost during rain and accumulate at the bottom, thus affecting the overall moisture retention effect.

[0005] In summary, a bentonite multilayer permeable water-retaining device is needed to solve the above problems. Utility Model Content

[0070] When it is necessary to clean the cover plate 2, the rectangular clip 33 is engaged with the rectangular clip frame 32, and then the operating rod 34 can be rotated to make the rotating rod 31 rotate, which in turn drives the first brush plate 38 and the second brush plate 312 to rotate. While the rotating rod 31 rotates, it can also drive the mixing plate 314 to rotate, which can cooperate with the rotating protrusion 36 to rotate, thereby mixing the soil between the auxiliary circular frame 1 and the cover plate 2.

[0071] When it is necessary to disassemble and replace the first brush plate 38 and the second brush plate 312, the threaded clamping rod 311 is separated from the first screw hole 39 and the second screw hole 310, and then the rectangular clamping block 37 is separated from the rectangular clamping frame 35 for disassembly and replacement.
