Centralized pneumatic type fertilizer ejecting device for granular fertilizer

Abstract

The invention discloses a centralized pneumatic type fertilizer ejecting device for granular fertilizer. The centralized pneumatic type fertilizer ejecting device comprises an air pump system, a fertilizer ejecting rack, a spiral mechanical quantitative fertilizer supply device, a fertilizer box, a motor transmission system, a control system, a 12V lithium battery, a transverse fertilizer ejectingand distributing device and a coupler. The centralized pneumatic type fertilizer ejecting device has the advantages that a fertilizer ejecting mode that spiral mechanical quantitative fertilizer supply and transverse air flow are distributed into six rows is adopted, the rotating speed of the spiral mechanical quantitative fertilizer supply device is adjusted by adopting the motor transmission system, the control system and the lithium battery, and therefore the fertilizer ejecting amount can be adjusted; the transverse fertilizer ejecting and distributing device can realize full mixing, conveying and uniform distributing of the air flow and the granular fertilizer by adopting the Venturi principle; and the centralized pneumatic type fertilizer ejecting device for the granular fertilizercan serve as an independent fertilizer ejecting device or a fertilizer ejecting part of a seeding machine in the fertilization process of multiple crops such as oilseed rape, rice and corn, and therefore comprehensive utilization can be realized so as to lower the application cost, the device utilization rate can be increased, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of crop fertilization equipment, in particular to a concentrated pneumatic fertilizer discharge device for granular chemical fertilizers. Background technique [0002] Timely and appropriate fertilization is to provide sufficient nutrients to crops and obtain better crop population structure and yield. Therefore, appropriate and precise fertilization is a key component of modern agricultural development. At present, the main problem of fertilization is excessive application of chemical fertilizers and fertilization based on experience, resulting in unreasonable fertilization and low utilization rate of chemical fertilizers; at the same time, it causes many problems such as soil, water, air and environmental pollution, mainly including soil compaction, water quality and oxidative , The problem of environmental pollution. Therefore, the Ministry of Agriculture of the People's Republic of China has proposed an...
