Description

Technical Field

[0001] The present invention relates to the technical field of soil and water moisturizing devices, and particularly to a bentonite multi-layer infiltration soil and water moisturizing device. Background Art

[0002] Bentonite is also called montmorillonite, saponite or bentonite rock. Bentonite is a non-metallic mineral mainly composed of montmorillonite, and some properties of bentonite are also determined by montmorillonite. Montmorillonite can be various colors such as yellowish green, yellowish white, gray, white, etc. It can be in dense massive form or in loose earthy form. When rubbed with fingers, it has a slippery feeling. When small pieces are added with water, the volume expands several times.

[0003] Considering that bentonite will swell when encountering water, making bentonite have good water absorption, so bentonite is often used as a moisturizing material. During the process of soil and water moisturizing, it is necessary to assist in moisturizing water in different strata. Therefore, some bentonite soil and water moisturizing devices with special structures and functions can be applied.

[0004] Generally, the traditional soil and water moisturizing device directly mixes bentonite with soil and then lays it on the ground that needs to be moisturized. Sometimes a covering net is laid after laying to prevent loss. This can reduce the loss of bentonite, but the bentonite laid on the surface has a low penetration force for moisturizing, resulting in a good moisturizing effect only for the surface layer depth, limited moisturizing ability for the bottom layer, and the moisturizing water on the surface layer is easy to dry, thus reducing the overall moisturizing effect. And the form of the covering net is likely to cause the loss of bentonite in rainy days and then gather at the bottom, thus affecting the overall moisturizing effect.

[0005] In summary, it is necessary to propose a bentonite multi-layer infiltration soil and water moisturizing device to solve the above problems. Summary of the Invention

When the rotating round rod 31 rotates, the stirring plate 314 can be driven to rotate, and then the stirring protrusion 36 can be rotated to mix the soil between the auxiliary round frame 1 and the cover plate 2.
