Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilization technology, specifically a fertilization device with soil covering function. Background Technology

[0002] Covering fertilizer with soil after application is an important operation in agricultural production. Its core purpose is to improve fertilizer utilization, reduce nutrient loss, and create more favorable conditions for crop growth. It avoids direct exposure of fertilizer to the air, reduces the loss of nitrogen (such as urea and ammonium nitrogen fertilizer) due to volatilization, and prevents fertilizer from being washed away by rainwater and irrigation water. It is especially effective for easily soluble fertilizers (such as potassium nitrate and ammonium sulfate). Fertilizer mixing is a common fertilization method in agricultural production. By scientifically mixing different types of fertilizers, it is possible to achieve nutrient complementarity, improve fertilizer efficiency, and reduce the number of fertilizations. Mixed fertilizers should not be stored for a long time, especially combinations with strong hygroscopicity or easy reactions (such as urea and superphosphate). They should be mixed and applied immediately to avoid nutrient loss or deterioration of physical properties.

The second valve is opened, and the quantitatively conveyed fertilizer falls into the mixing tank. The output shaft of the drive motor rotates, driving the stirring head to rotate. The rotating stirring head mixes the various fertilizers evenly. The first electric valve is opened, allowing the mixed fertilizer to fall. The mixed fertilizer falls into the discharge frame. The vibration motor vibrates, causing the discharge frame to vibrate, spreading the fertilizer evenly on the discharge frame. The baffle guides it to be evenly distributed on the discharge frame. The fertilizer falls evenly onto the ground through the discharge frame, which is beneficial for the mixed fertilizer to be immediately and evenly spread on the ground, avoiding the loss of nutrients from the mixed fertilizer.
