Precise fertilizer feeder

Abstract

The invention discloses a precise fertilizer feeder. The fertilizer feeder includes a shell and a spiral sheave. The shell is provided with a conveying flow channel. The spiral sheave is arranged in the conveying flow channel. The spiral sheave is used for conveying fertilizer from a conveying flow channel inlet to a conveying flow channel outlet. The fertilizer feeder is also provided with an opening adjustment mechanism for adjusting the opening degree of the conveying flow channel inlet and / or conveying flow channel outlet. The fertilizer feeder solves the problem of a conventional fertilizer feeder that the accuracy of fertilizer feeding amount is affected by blockage, overhead, adhesion and the like caused due to the fertilizer is prone to moisture, and improves the accuracy of the fertilizer feeding of the fertilizer feeder. The fertilizer feeder is suitable for precise and variable fertilizer feeding control field in precision agriculture, and can realize the precise feeding ofthe fertilizer application amount determined by a control system.

Description

technical field [0001] The invention relates to an agricultural implement, in particular to a precision fertilizer discharger. Background technique [0002] The traditional agricultural fertilization technology is mainly based on fertilization, and the utilization rate of chemical fertilizers is low. On the one hand, it increases production costs and causes pollution to the environment; on the other hand, the uniformity of fertilization is poor, which also affects crop yields to varying degrees. Precision agriculture is recognized as an important mode of modern agricultural production in the new century. In the field of precision agriculture, the accuracy of fertilizer discharge is related to the structure and control system of the fertilizer discharger. How to achieve precise fertilizer discharge still needs to be studied and improved. At present, the most widely used is the outer grooved wheel fertilizer discharger, which has a simple structure, good versatility, and a la...

AI Technical Summary

Problems solved by technology

At present, the most widely used is the outer grooved wheel fertilizer discharger, which has a simple structure, good versatility, and a large adjustment range of fertilizer discharge, but there are still the following deficiencies in the precise control of fertilizer discharge: 1. Low discharge and low speed 2. Due to the friction between the fertilizers, the fertilizer produces a fertilizer driving layer around the outer grooved wheel, so it is difficult to control the amount of fertilizer; 3. Due to the vibration It often leads to fertilizer leakage and affects the stability of fertilizer discharge; 4. Due to the hygroscopicity of fertilizers, the fluidity decreases, resulting in overhead, blockage and adhesion, which directly affect the precise control of fertilizer discharge.
