[0002] Fertilizer is the indispensable material basis in the growth process of crops, it can supply nutrients and make plants develop and grow, in the fertilizer production process, the mixing of fertilizer is a vital link. The traditional fertilizer mixing mode often relies on manual or simple mechanical equipment, and different fertilizer raw materials are put into the mixing equipment according to certain proportion for mixing. However, this mode has many deficiencies.

[0003] Firstly, the traditional mode is difficult to realize the accurate quantitative mixing of fertilizer. Due to the error of manual operation and the limitation of mechanical equipment precision, the mixing ratio is often inaccurate, thereby affecting the quality and effect of fertilizer.

[0004] Secondly, the traditional mode is prone to uneven distribution of raw materials in the mixing process. Since the input of raw materials is carried out in sequence, some raw materials are often locally accumulated in the mixing tank, while other raw materials are relatively less, which will lead to poor uniformity of the mixed fertilizer. Therefore, we propose a fertilizer quantitative mixing device. UTILITY MODEL CONTENT
