Description

A fertilizer mixer

technical field

The invention belongs to the technical field of agricultural machinery and equipment, and relates to a fertilizer mixer.

Background technique

The macronutrient nitrogen, phosphorus, and potassium in the soil usually cannot meet the needs of crop growth, and fertilizers containing nitrogen, phosphorus, and potassium need to be used to make up for it. In the micronutrient elements, except for chlorine, which is not lacking in the soil, several other nutrients Elements require the application of trace element fertilizers. Chemical fertilizers are fertilizers made by chemical methods that contain one or several nutrient elements needed for the growth of crops. The abbreviation of chemical fertilizers is called unit fertilizers that contain only one nutrient element that can indicate the content, such as nitrogen fertilizer, phosphorus fertilizer, Potassium fertilizers and minor macroelement fertilizers and trace element fertilizers, chemical fertilizers containing two or three of the three nutrients nitrogen, phosphorus, and potassium, and their contents can be indicated, are called compound fertilizers or mixed fertilizers. In the process of fertilizer production, it is necessary to mix various unit fertilizers, or add unit fertilizers to the mixed fertilizers. Due to the long-term storage of chemical fertilizers, there will be condensation, so there will be hard lumps in the fertilizers, and it is difficult to mix uniformly, which will affect the quality of fertilizers.

Contents of the invention

The object of the present invention is to solve the above-mentioned problems in the existing technology, and propose a fertilizer mixer, which can automatically grind and stir fertilizers, has good mixing quality and high degree of automation.
