Electrically-driven pneumatic precise concentrated fertilizer discharging system

Abstract

The invention discloses an electrically-driven pneumatic precise concentrated fertilizer discharging system which comprises a material box, a machine shell, an internal seat body, a fertilizer discharging shaft roller, a fertilizer stirring shaft, a motor, a control box, a satellite positioning module, a fan, a gas-solid mixer, a residual amount sensor, a blockage sensor and the like. The device is convenient to mount on carriers such as a rice transplanter or a tractor and has the advantages of miniaturization, modularization and intellectualization, the control box realizes synchronization of the rotation speed of the fertilizer feeding motor and the running speed of the carriers through the satellite positioning module, blockage in the fertilizer feeding system can be avoided by utilizing an air supply mode, and the device can adapt to complex working conditions of paddy fields and cultivated land for precise fertilization. Resource waste and environmental pollution can be reduced, fertilizer utilization rate is increased, and food safety in China is guaranteed.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, relates to a fertilization device for various crops in the field, and in particular relates to an electric-driven air-feeding type precision centralized fertilizer discharge system. Background technique [0002] Chemical fertilizer is an important agricultural production material and an important way to increase grain output. The application of chemical fertilizer has become one of the important means to increase grain output in many countries. The lateral deep fertilization technology refers to the fertilization technology of ditching and fertilizing and covering the soil in the area of ​​3-5 cm on one side of the rice root system and a depth of 5 cm while the rice transplanter is working. Deep side fertilization can effectively reduce the loss and waste of chemical fertilizers, improve the operation efficiency and the utilization rate of chemical fertilizers, reduce labor intensity, save c...

AI Technical Summary

Problems solved by technology

However, the fertilizer discharge system under the large width has the problems of large size, heavy, slippery ground wheels, inconsistent and uneven fertilizer discharge in each row, manual adjustment of fertilizer application, and not good at various working conditions, such as using rice transplanters in paddy fields Perform side-deep fertilization

And when discharging powdery and wet chemical fertilizers, it is easy to appear overhead and broken bars, what's more, the fertilizer discharge groove wheel adheres and the fertilizer discharge pipe is blocked

And in paddy fields or complex bumpy fields, the slippage of the ground wheel during the machine advance will cause the drive layer to be disordered, which directly affects the stability of precision fertilization
