Description

Technical Field

[0001] The utility model relates to the technical field of tobacco fertilization, in particular to a precise sprayer for liquid fertilizer on tobacco leaves. Background Art

[0002] As an important economic crop, fertilization management is particularly critical during the growth of tobacco. Tobacco fertilization mainly includes base fertilizer and topdressing, which aims to ensure that tobacco plants get sufficient nutrition during the growth cycle. In addition to traditional soil fertilization, foliar fertilization is also increasingly valued in tobacco production. Foliar fertilization is to spray the fertilizer solution directly on the tobacco leaves. This method has the advantages of small dosage, fast absorption, high efficiency, etc., which is conducive to the growth of tobacco.

[0003] The utility model patent with authorization announcement number CN219961347U discloses a fertilization device for tobacco planting, which includes a fertilizer box, the top of which is provided with an adjustable fertilization assembly, and the inner bottom end of the fertilizer box is provided with a stirring and sweeping assembly; the stirring and sweeping assembly includes a waterproof box, a third motor, a fixed block, a plurality of stirring rods, a plurality of springs and a plurality of brush rods, the bottom end of the waterproof box is fixedly connected to the inner bottom end of the fertilizer box, the third motor is fixedly installed on the inner wall of the waterproof box, the bottom end of the fixed block is fixedly connected to the output end of the third motor, one end of a plurality of stirring rods is fixedly connected to the side wall of the fixed block, one end of a plurality of springs is fixedly connected to the inner side of the bottom end of the stirring rod, and the top end of a plurality of brush rods is fixedly connected to the other end of the spring. The device adopts the design of a stirring and sweeping component, which is specifically started by a third motor that is waterproof and sealed by a waterproof box to drive the fixed block to rotate, thereby driving the stirring rod to rotate to stir and mix the fertilizer, and through the reaction force of the spring, the brush rod is extended from the bottom end of the stirring rod to fit with the inner bottom end of the fertilizer box. The rotation of the stirring rod drives the brush rod to rotate to clean and stir the fertilizer settled at the bottom of the fertilizer box, thereby achieving the purpose of effectively stirring the fertilizer settled at the bottom of the fertilizer box and avoiding the precipitation and accumulation of fertilizer particles that affect the fertilization effect.

[0004] Although the tobacco planting fertilization device can avoid affecting the fertilization effect by stirring the fertilizer at the bottom of the fertilizer box, the device still has the following problems when in use: although the nozzle provided in the device can swing vertically, the angle of the fertilizer liquid sprayed is arc-shaped when spraying the fertilizer liquid, so it is difficult to directly spray the fertilizer liquid accurately on the leaf surface of the tobacco leaves, and therefore cannot meet the demand for foliar fertilization during tobacco planting. In view of this, we propose a precise sprayer for tobacco foliar liquid fertilizer. Utility Model Content
