A spray head of a fertilizer spreader that is easy to adjust the angle

Abstract

The invention discloses a fertilizer applicator nozzle that is easy to adjust the angle. The fertilizer applicator nozzle that is easy to adjust the angle includes a nozzle main body, a connecting mechanism, a deflection mechanism, a driving mechanism and a reciprocating mechanism. One end of the inner cavity of the nozzle main body is fixedly installed with a connection mechanism. The invention pushes the support ring to move in the inner cavity of the nozzle, so that the nozzle can be supported by the support ring, thereby expanding the diameter of the nozzle, thereby increasing the amount of chemical fertilizer sprayed, and the No. 2 motor is controlled to drive the worm to rotate, and one side of the worm is engaged. A worm gear is connected, and one side of the worm gear is engaged with the sector gear, so that the sector gear can be driven to rotate around the axis under the cooperation of the worm gear and the worm, so that the nozzle can be adjusted left and right, and the eccentric gear can be driven to rotate by controlling the No. 3 motor. , the surface of the eccentric wheel pulls the main body of the nozzle to perform a reciprocating swing motion through the connecting rod, so that the fertilization area can be increased during fertilization, and the use is more flexible and convenient.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery equipment, in particular to a nozzle of a fertilizer applicator which is convenient for angle adjustment. Background technique [0002] Fertilization refers to the agricultural technical measures of applying fertilizers to the soil or spraying them on plants to provide the nutrients needed by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, fertilize soil and improve economic benefits. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development. The main basis for fertilization is soil fertility level, crop type, target yield, climate environment and fertilizer characteristics, so as to select the appropriate fertilizer, estimate the amount of fertilizer required, and determine the time and mode of fertilization. ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a fertilizer applicator nozzle that is easy to adjust the angle to solve the problem that the spray angle of the nozzle is manually adjusted during the use of the existing fertilizer applicator nozzle in the above-mentioned background technology, resulting in that the nozzle cannot be adjusted during the fertilization process. The spray angle is adjusted, and the adjustment direction is less, and the use flexibility is poor. The existing fertilizer applicator nozzle cannot adjust the opening diameter of the nozzle during use, and thus cannot increase the amount of fertilizer applied during fertilization.
