Description

Technical Field

[0001] The utility model relates to the technical field of sand barrier machines, and particularly relates to a rolling wheel adjustable crawler self-propelled sand barrier machine. Background Art

[0002] The existing crawler self-propelled sand barrier machine consists of a power system, a diesel engine, a speed reducer, a steering handle, a grass pressing rolling wheel, crawlers, load-bearing walking wheels, a seat, a handrail, a sunshade, a counterweight box, etc. The rolling depth of this crawler self-propelled sand barrier machine is 15 to 30 cm, equipped with a 35-horsepower diesel engine for driving, configured with a crawler chassis, suitable for sand slopes within 40 degrees. The hydraulic push rod controls the lifting of the rolling wheel to improve the downward pressure ability. A seat, a handrail, and a sunshade are installed. By operating the steering handle to change the direction, the steering is flexible, the operation is simple and convenient, saving time and effort. When the crawler self-propelled sand barrier machine is working, it is powered by a diesel engine, the crawlers move forward, and it moves forward by pressing the grass with the grass pressing rolling wheel. A 15- to 30-centimeter-deep gully will appear under the straw. The straw will form a sand barrier that can block the wind and sand under the action of the rolling wheel and the gully, effectively slowing down the wind speed, reducing the erosion disasters in deserts and sandy areas, reducing land desertification, preventing wind and sand erosion, effectively stopping the flow of wind and sand, and playing a role in wind prevention and sand fixation.

[0003] A plurality of teeth are installed on the outside of the grass pressing rolling wheel. The teeth can bear the impact suffered by the grass pressing rolling wheel during movement, reducing the probability of damage to the rolling wheel body. At the same time, the teeth enable the rolling wheel to better compact the sand barrier material. The sharp part of the teeth can penetrate into the internal part of the sand barrier material, and through the pressure generated by the rolling of the grass pressing rolling wheel, the sand barrier material is tightly compacted to form a stable sand barrier structure.

[0004] When the teeth outside the grass pressing rolling wheel are damaged, in order to ensure the effect of the grass pressing rolling wheel, it is necessary to replace the whole or use welding tools to install new teeth, which increases the maintenance cost and the maintenance difficulty at the same time.
