One-device multi-line spiral disturbance cone centrifugal type granular fertilizer concentrated discharger

Abstract

The invention discloses a one-device multi-line spiral disturbance cone centrifugal type granular fertilizer concentrated discharger which comprises an upper shell, a with-speed control system, a lower shell connected with the upper shell through bolts, and a middle disc installed between the lower shell and the upper shell. An independent cavity is formed between the middle disc and the upper shell. A fertilizer discharge pipe is communicated with the independent cavity. The with-speed control system comprises a photoelectric coded disc connected with a rotating shaft of one wheel of a fertilizer application moving device, a photoelectric sensor matched with the photoelectric coded disc, a main control chip for obtaining a photoelectric signal and outputting a control signal, a DC motor capable of driving a fertilizer discharge shaft to rotate, and a controller. The photoelectric sensor, the photoelectric coded disc, the main control chip and the DC motor are electrically connected with the controller. The one-device multi-line spiral disturbance cone centrifugal type granular fertilizer concentrated discharger realizes one-time multi-line granular fertilizer discharging and can ensure the precise discharge amount and the consistent discharge amounts of all lines.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a multi-row spiral disturbing cone centrifugal granular fertilizer collector. Background technique [0002] Fertilization is of great significance to the safety, stability and development of agricultural production. The rapid development of world agriculture, in addition to relying on the progress of biotechnology and the expansion of arable land and irrigated areas, is basically based on chemical fertilizers and pesticides and mineral energy. Obtained under the condition of a large amount of input. China is the country that uses the largest amount of chemical fertilizers in the world. The average amount of chemical fertilizers used per mu of crops in my country is much higher than the world average. The crop yield corresponding to the amount of application is decreasing year by year, and the problem of diminishing marginal effect of chemical fertilizers on increas...

AI Technical Summary

Problems solved by technology

[0003] Farmers have the misconception that the more fertilization, the better the effect. Not only is it difficult to guarantee the utilization rate of chemical fertilizers, but excessive fertilization will cause soil compaction, pollute groundwater, and cause direct or indirect economic losses.

The control of agricultural non-point source pollution should be solved from the application of chemical fertilizers. The application of chemical fertilizers can be reduced and the utilization rate of chemical fertilizers can be improved through precise fertilization based on soil testing formula. The accuracy of precise fertilization is mainly reflected in the accuracy of the amount of fertilizer applied and the accuracy of the depth of fertilization. The accuracy of fertilization amount needs to be realized through the collector, but the current fertilizer discharge device is difficult to ensure the consistency of the fertilizer amount of each fertilizer discharge pipe, and there are problems such as complex mechanical structure and large power consumption of the air-delivery type.
