Introduction to the types of fertilizing machines, what are the benefits of using fertilizing machinery?

The types of fertilizers introduce the latest pictures of fertilizing machinery. Centrifugal fertilizer spreaders are the most commonly used spreaders in Europe and the United States.It is a rotating fertilizer spreader driven by a power output shaft that uses centrifugal force to sprinkle fertilizer out.There are two types of single-disc and double-disc.The fertilizer spreading tray is generally equipped with 2-6 blades. Their installation position on the turntable can be radial, or they can be tilted forward or backward relative to the radius; the shape of the blades can be straight or curved.The forward-leaning leaves can spread the fertilizer with good fluidity farther, while the backward-leaning leaves are not easy to adhere to the moisture-absorbing fertilizer.

Classification of fertilizer spreader

(1) Full-width fertilizing machine

The basic feature of this kind of fertilizing machine is to fertilize evenly within the full width of the machine.Its working principle can be divided into two categories: one is composed of a plurality of double-blade rotary fertilizer dryers arranged laterally (Figure 2); the other is composed of chain fingers mounted on a chain moving laterally, fertilizing along the width of the entire machine.

(2) Pneumatic wide-format fertilizer spreader, foreign countries have developed a variety of types of pneumatic wide-format fertilizer spreaders (Figure 4) In recent years, the working principle is roughly the same, they all use the high-speed air flow generated by the high-speed rotating fan, and cooperate with the mechanical fertilizer draining device and sprinkler head to spread fertilizer, lime and other soil improvers in a wide and efficient manner.

Classification of fertilizer fertilizers

A reasonable way to apply seed fertilizer is to install a fertilizer device on the planter and apply seed fertilizer at the same time as sowing.At present, most seeders in developed countries abroad are equipped with fertilizer application devices. For example, about 45% of grain sowers and 60% of corn seeders in the United States are equipped with fertilization devices.

One billion mu of cultivated land in my country is deficient in phosphorus, and it is generally necessary to apply fertilizer, but the existing planter cannot yet meet this requirement.The machine used for seed fertilizer mixing is to discharge fertilizer and seeds into the same seed delivery pipe and apply it to the bottom of the ditch opened by the same trencher.The mixing of seed and fertilizer can easily “burn” the seeds with fertilizer.

Classification of liquid fertilizer fertilizers

Liquid fertilizers are divided into chemical liquid fertilizers and organic liquid fertilizers.Chemical liquid fertilizers have a strong corrosive effect on metals and are easily volatile.Therefore, except for some liquid fertilizers that can be applied to crop stems and leaves by spray method, most of them need to be applied to the soil to prevent volatilization, loss of fertilizer efficiency and burning of crops.Organic liquid fertilizer is composed of human, animal manure, urine and sewage.It often contains suspended solids or impurities. After fermentation treatment, it is diluted with water, filtered and then sprayed.Liquid fertilizer is easily absorbed by crops, has a fast fertilizer effect, and is mostly used for top dressing.
