Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology and solve the existing technology, the large-scale chemical fertilizer spreader has high limitations and cannot meet the needs of special environments such as fertilizer supplementation, fixed-point fertilization, and paddy fields. The front-back hand-operated fertilizer spreader , low automation, poor practicability, low load-bearing at one time, which affects the sight of the fertilizer; the back-type fertilizer spreader, the motor is directly set on the nozzle, and the fertilizer needs to hold the nozzle with the motor all the time during the fertilization process , the hand load is high, and the nozzle of the back-type fertilizer spreader must be lower than the height of the fertilizer body, so the operation limitations are relatively high. This invention proposes a method for preparing trace elements in compound fertilizers.

Embodiment approach

[0036] As an embodiment of the present invention, the wind disc includes a rotating shaft 32 and fan blades 33; the cross section of the fan blades 33 is designed in a "J" shape; when working, the wind disc will rotate counterclockwise due to the wind force, Therefore compound fertilizer can be thrown out from the side of the opening of shower head 3 when wind disk rotates, and because the effect of motion inertia is divergent shape, but because compound fertilizer all directly all sprays from the opening side of shower head 3, easy The phenomenon of uneven spraying on the left and right occurs, and the uniformity is not high. Therefore, by designing the cross-section of the fan blade 33 as a "J"-shaped structure, when the compound fertilizer is thrown out from the opening of the nozzle 3, it can be sprayed evenly at different rotation angles. Therefore, the uniformity of fertilizer spreading is higher and the spraying area is wider.

Abstract

The invention belongs to the technical field of fertilizer, and particularly relates to a preparation method of trace elements in compound fertilizer. A fertilizer applicator used in the method comprises a shell, a motor and a spray head, a housing is fixedly connected to the side surface of the right side of the shell, a motor is arranged in the housing, a first soft catheter is connected to theside face of the right side of the housing, the end of the first soft catheter is connected with a spray head, a second soft guide pipe is fixedly connected to the bottom of the machine shell on the side face of the right side of the machine shell, and the other end of the second soft guide pipe communicates with the spray head. According to the fertilizer applicator, automatic spraying of compound fertilizer is achieved, the requirements of various working environment conditions are met, the practicability is high, and use is convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a method for preparing trace elements in compound fertilizers. Background technique [0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It is very important for balanced fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. role. But it also has some disadvantages, such as its nutrient ratio is always fixed, and the types, quantities and ratios of nutrient elements required by different soils and different crops are varied, so it is best to test the soil before use to understand the texture of the field soil In addition, attention should also be paid to the application of unit fertilizers in order to obtain better results. [0003] Medium-trace element compound ...
