Description

Technical Field

[0001] The invention relates to the technical field of centrifugal separation devices, in particular to a crushed stone processing device for garden soil processing. Background Art

[0002] As people's spiritual and cultural needs continue to increase, the landscape requirements for their living environment are also getting higher and higher. Gardens can create beautiful landscapes and provide people with visual enjoyment through the combination of elements such as plants, water bodies, buildings, and sculptures. Gardens have various styles, and many gravels are used as embellishments in gardens. For example, in Japanese gardens, gravels are widely used to create dry landscapes. In modern gardens, gravels are also often used around water features in modern gardens as a filter layer or decorative layer. The use of gravels can also greatly enhance the visual effect of gardens.

[0003] Laying gravel on the soil of the garden can also improve the soil. The gravel above the soil can moisturize the soil, inhibit the growth of weeds, and keep the soil fertile. When laying gravel, it is necessary to screen and grade the gravel, remove oversized stones or oversized particles, and ensure that the particle size of the gravel is uniform. This can not only improve the landscape effect, but also ensure the flatness and stability of the paving. At the same time, when selecting gravel, it is also necessary to choose gravel without obvious edges and corners to prevent pedestrians or children from getting injured. However, there is currently a lack of such equipment for processing gravel, making it difficult to sort the gravel. Summary of the invention
