Pneumatic collection and discharge type granular fertilizer variable distribution device

Abstract

The invention discloses a pneumatic collection and discharge type granular fertilizer variable distribution device, which comprises a fertilizer variable distribution regulating device, a fertilizer shifting device, a fertilizer inlet pipe and fertilizer outlet pipes. The fertilizer shifting device is mounted in the upper middle of the fertilizer variable distribution regulating device, and the fertilizer variable distribution regulating device comprises a distribution device shell, a regulating disc, six sector sliders, a handle and bolts. The regulating disc is mounted on the distribution device shell, the six sector sliders are mounted in the distribution device shell through the bolts, and the handle is mounted on the regulating disc. The device has advantages that upper and lower layers of fertilizers can be outputted according to crop growth requirements, a proportion of the upper and lower layers of fertilizers can be controlled, and by timely crop fertilization in an appropriate amount, loss of the fertilizers is reduced, the utilization rate is increased, and a wide application range is realized; in addition, problems of failure of in effective proportion adjustment of thefertilizers in different layers, difficulty in control of the application amount of the fertilizers in different layers, and the like of an existing layered fertilization device are solved.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a pneumatic collection and discharge type granular fertilizer variable distribution device Background technique [0002] Fertilization technique is one of the important factors affecting crop yield. The amount of fertilizer required for different crop growth periods is also different. Timely and appropriate application of fertilizer can not only greatly increase the yield and quality of crops, but also reduce the loss of nutrients and improve the utilization rate of fertilizers. [0003] At present, wheat, corn, rice, soybeans and other crops in my country are fertilized at the same time as they are sown to provide nutrients for the growth of the crops at the seedling stage. However, high-stalk crops such as corn have a short growth cycle and require a large amount of fertilizer, so they must be continuously topdressed. Topdressing is time-consuming and laborious, and the types of ...

AI Technical Summary

Problems solved by technology

The current layered fertilization device has a large volume. Since the fertilization device is installed behind the subsoiler shovel, it will greatly increase the resistance of the subsoiler shovel, which will not only increase the energy consumption of the unit, but also affect the return of soil, resulting in insignificant fertilizer layering effects. Therefore The volume of the fertilization device should be reduced as much as possible, but as the volume decreases, the fertilizer is prone to clogging, and the amount of fertilization per layer is more difficult to control
