Fertilizer applicator applied to tobacco field to regulate fertilizer application depth

Abstract

The application relates to the field of agricultural machines, in particular to a fertilizer applicator applied to a tobacco field to regulate fertilizer application depth. The middle part of a frameis provided with a travelling device; the rear part of the frame is provided with a fertilizer application lifting device and a ridging device; the rear part of the travelling device is provided witha depth detector; the travelling device is equipped with a rotating speed sensor used for detecting a running speed signal of the fertilizer applicator; an input end of a main control unit of a fertilizer application control device is connected with the depth detector and the rotating speed sensor so as to receive a detected tobacco field depth signal and running speed signal, and an output end ofthe main control unit is connected with the fertilizer application lifting device and the ridging device; and the main control unit controls the fertilizer application depth and the fertilizer application rate of the fertilizer application lifting device according to the received tobacco field depth signal and running speed signal, and simultaneously controls the ridging height of the ridging device. The fertilizer applicator has high automation degree, and by combined use of the fertilizer application lifting device and the fertilizer application control device, the nitrogen application rateand the fertilizer application depth can be reasonably regulated according to the height of a tobacco field ridge, so that the efficiency of fertilizer application is fully improved.

Description

【Technical field】

[0001] The present application relates to the field of agricultural machinery, in particular to a fertilizer applied to tobacco fields to adjust fertilization depth. 【Background technique】

[0002] Tobacco is one of the important economic crops in China. How to improve the yield and quality of tobacco is an important issue that directly affects the income of tobacco farmers and the development of the tobacco industry. Rational fertilization is an important guarantee for high-quality and suitable production of flue-cured tobacco. Only a certain amount of fertilization can achieve the high quality of tobacco leaves and maximize economic benefits. For the same flue-cured tobacco variety, different tobacco planting areas and different soil physical and chemical properties, the suitable nitrogen application rate is not the same, and the soil physical and chemical properties in the tobacco planting area will also change due to the long-term different nitrogen app...
