Description

Technical Field

[0001] This utility model relates to the technical field of windbreak and sand fixation devices, specifically a grid-based windbreak and sand fixation device based on a bentonite mixed structure. Background Technology

[0002] The main mineral component of bentonite is montmorillonite, which accounts for 85-90% of the total content. Some of the properties of bentonite are determined by montmorillonite. Montmorillonite can be in various colors such as yellow-green, yellow-white, gray, white, etc. It can be in the form of dense blocks or loose soil. It feels slippery when rubbed with your fingers. Small pieces can expand in volume several times to 20-30 times when water is added. It is suspended in water and becomes a paste when there is little water.

[0003] Considering the property of bentonite to swell when it comes into contact with water, it is often used in the field of windbreak and sand fixation. When sand mixed with bentonite comes into contact with water, it swells and locks in water, thus reducing water loss. In windbreak and sand fixation, bentonite needs to be used in conjunction with windbreak and sand fixation structures. Therefore, some windbreak and sand fixation devices with special structures and functions can be applied.

[0004] Traditional windbreak and sand-fixing devices typically consist of a wire mesh structure with a frame for fixation. This wire mesh covers the sandy ground, effectively preventing wind erosion and fixing the sand. However, even with a large area of ​​wire mesh and a fixed frame, the sand can still be washed away by water flow, resulting in clumps of sand. In such cases, bentonite is usually added to stabilize the sand. However, the added bentonite cannot fully mix with the underlying sand, leading to further erosion of the sand at the bottom. Some wire mesh was not laid with bentonite before installation. When additional bentonite was needed later, the top bentonite, due to its water absorption and expansion effect, could not mix with the sand at the bottom, resulting in a narrower top space. This made the wire mesh more prone to deformation and separation. Furthermore, in strong winds, the sand inside the wire mesh could still be blown up and spread to the surrounding area, causing stratification on the mesh. This meant that the amount of sand increased in the windward direction, while the sand in the opposite direction was severely lost, which was very inconvenient.

[0005] In summary, a grid-based windbreak and sand-fixing device based on a bentonite hybrid structure is needed to solve the above problems. Utility Model Content

[0042] Under the action of the bentonite mixing structure 3, after the wire mesh 2 is laid, when additional bentonite is laid according to the actual soil erosion situation, the additional bentonite can be effectively mixed with the sand at the bottom. Furthermore, the bentonite remaining at the top of the wire mesh 2 can be swept into the sand at the bottom for mixing, thus ensuring thorough mixing between the bentonite and the sand, thereby improving the overall sand-fixing effect.

A rotating round block 54 is fixedly connected to the outer surface of the rotating round rod 53. The outer surface of the rotating round block 54 is fixedly connected to the outer surface of the rectangular outer frame 55.

[0056] By setting the rotating rod 53 and the rotating block 54, the angle of the rectangular outer frame 55 can be adjusted.

[0061] The overall working principle described above is as follows:

[0062] In use, the fixing cylinder 43 is inserted into the inner wall of the first fixing hole 42. At this time, the annular block 44 can limit the position of the fixing cylinder 43 and fit the fixing cylinder 43 against the top of the sand. Then, the long rod 48 is inserted into the inner wall of the round cylinder 45, the annular block 44 and the fixing cylinder 43 to fix the sandy ground. At the same time, the side net body 46 and the side-curved net body 47 can be fixed. The side-curved net body 47 can assist in blocking sand blown towards the side net body 46 during wind.

[0063] At the same time, the short rod 412 is inserted into the inner wall of the second fixing hole 411, and then the hammering tool is used to hammer the hammering auxiliary block 415 so that it can be fixed to the sandy ground.

[0064] At this time, rotate the protective net body 56 so that the protective net body 56 can drive the rotating round rod 53 and the rotating round block 54 to rotate, and then drive the rotating disk 58 to rotate. When it is rotated to the appropriate position, rotate the threaded clamp rod 510 so that the threaded clamp rod 510 can be fixed with the threaded clamp hole 59. The sand can be blocked by the protective net body 56.

[0065] When bentonite needs to be added, it is sprinkled onto the wire mesh 2. Then, the fixing rod 311 is pulled to release it from the sand. The fixing rod 311 is then pushed to allow the rectangular slider 32 to slide on the inner wall of the rectangular ring plate 31, which in turn drives the mixing screen plate 36 to move, thereby mixing the bentonite and sand. At the same time, the rectangular cleaning plate 39 can assist in mixing the sand and bentonite on the top of the wire mesh 2.
