Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer mixing and crushing, in particular to a soil fertilizer mixing and crushing device. Background Art

[0002] Soil-fertilizer mixing and grinding refers to the process of mixing different types of soil and fertilizer together and grinding them through mechanical equipment. This can fully and evenly mix the soil and fertilizer, making it a fertilizer mixture that is rich in comprehensive nutrients and suitable for crop growth. In agricultural production, soil-fertilizer mixing and grinding helps to improve fertilization effects and crop yields. Through mixing and grinding, the nutrients in the fertilizer can be better integrated with the soil, providing the nutrients needed by plants. At the same time, the crushed fertilizer particles are finer, which is conducive to the root system to absorb nutrients, improve fertilizer utilization rate and the absorption capacity of crop roots. In current life, soil and fertilizer are generally crushed by grinding rollers, and then the crushed soil and fertilizer are mixed by mixing devices.

[0003] Soil and fertilizer are directly placed on the top of the crushing roller for crushing. When a large amount of soil and fertilizer accumulates on the top of the crushing roller, it is easy to cause the crushing roller to get stuck. After one crushing by the crushing roller, some soil and fertilizer are still not completely crushed, which causes the incompletely crushed soil and fertilizer to be mixed, resulting in poor soil and fertilizer mixing effect.
