Rice field fertilizer applying device

Abstract

The invention discloses a rice field fertilizer applying device which comprises a fertilizer box. A scattering disc is arranged below the fertilizer box. The scattering disc is provided with a scattering cavity in a cone frustum shape, and scattering plates are distributed inside the scattering cavity circumferentially. By arranging the scattering plates driven by a frequency conversion motor andthe scattering disc provided with the cone frustum shaped scattering cavity, centrifugal scattering of fertilizer is achieved, the fertilizer scattering efficiency is improved, and meanwhile fertilizer scattering is more uniform; by arranging a discharging pipe and discharging spiral blades, quantified discharging is achieved while blockage of a discharging pipe is avoided, and uniform scatteringis ensured.

Description

technical field [0001] The invention relates to the field of agricultural fertilization machinery, in particular to a paddy field fertilization device. Background technique [0002] Soil must be considered in fertilization because: First, fertilization is only required when the soil has insufficient supply of a certain nutrient, and it is not necessary to apply all the necessary elements to the soil. Because the supply of most nutrients is sufficient, otherwise it will cause waste and even cause crop poisoning. This point is sometimes overlooked. Second, after the fertilizer is applied to the soil, a series of changes will occur, which will affect the fertilizer effect to varying degrees. If the soil is not considered, it is impossible to talk about real and reasonable fertilization. For example, the application of nitrate nitrogen fertilizer in paddy fields will inevitably reduce the fertilizer efficiency and so on. [0003] In the process of fertilizing paddy fields, no...

[0003] In the process of fertilizing paddy fields, not only base fertilizer but also topdressing and fertilization are required many times. The traditional manual fertilization method is inefficient and the uniformity of fertilization is poor. In addition, after transplanting rice seedlings, it is more troublesome to manually walk in the paddy field, resulting in more laborious fertilization.
