Description

Technical Field

[0002] Soil greening refers to the activity of planting plants on the land to improve the environment. Soil greening helps to improve people's living standards and living environment, and is of great significance to the protection of the ecological environment. Healthy soil is the basis of all life. It can not only provide water, food, clean air, stable climate and health, but also is the key to protecting land and water resources, sustainably supplying food, clean water and responding to climate change. In the process of soil greening, plants such as lawns or plants need to be planted on the land. However, if there are large volumes of industrial waste or stones in the soil, it will affect the penetration and growth of plant roots in the soil, and industrial waste will also pollute the environment. Therefore, before soil greening, the soil needs to be treated. When treating the soil, it is necessary to use an excavator to dig out the soil, and then use conveying equipment such as belt conveyors to transport the soil to the screening equipment, and then use the screening equipment to screen the soil, and finally use the conveying equipment to transport the screened soil back to the excavation site for backfilling, so that the soil is more suitable for plant growth. However, this treatment method requires the deployment of a large number of mechanical equipment, and the excavated soil needs to be transported to the screening equipment, and then the screened soil is transported back to the excavation site for backfilling, which results in a long soil treatment time and low treatment efficiency.
