Efficient automatic fertilization device for agricultural science and technology

Abstract

The invention belongs to the technical field of agricultural fertilization devices, and particularly relates to an efficient automatic fertilization device for agricultural science and technology. Thedevice comprises a bottom plate and spreading plates. The bottom plate and a top plate are fixedly connected through a supporting rod. A rotating rod is inserted into the top plate; and the top end of the rotating rod is in transmission connection with a driving motor fixed to the upper surface of the top plate. A plurality of groups of positioning cylinders movably sleeve the position, between the bottom plate and the top plate, of the rotating rod; the positioning cylinders are fixed at the edge of the rotating rod through positioning screw rods; water absorption cotton sleeves are fixedlyarranged on the inner walls of the positioning cylinders; the spreading plates are fixedly arranged at the outer edges of the positioning cylinders; and fertilizer in the spreading plates can be sprayed out from spreading holes at the edges of the spreading plates, then the effect of large-area spreading can be achieved, the single spreading area is increased, due to the fact that the multiple layers of spreading plates are arranged, the spreading plates located at different heights can throw the fertilizer to different positions away from the spreading plates according to the throwing principle, furthermore, the fertilizer is uniformly spread within the spreading range, and the spreading effect is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilization devices, in particular to an efficient automatic fertilization device for agricultural science and technology. Background technique [0002] The macronutrients 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. Among the micronutrient elements, except chlorine, which is not lacking in the soil, several other nutrient elements need to be supplemented by the application of micronutrient fertilizers. [0003] In the prior art, when farmers fertilize crops, they often use the method of direct spreading by hand. This method needs to hold a pot containing chemical fertilizer in one hand, and spread the chemical fertilizer in the other hand. It is obviously more laborious to go back and forth. Although various fertilization devices have been prop...
