Problems solved by technology
[0006] In order to overcome the problem that the nozzle spraying area is difficult to be quickly adjusted in the existing precise target spraying technology, the purpose of the present invention is to provide a fan-shaped nozzle that can change the spray angle by adjusting the angle of the groove, and improve the structure of the existing fan-shaped nozzle. Retrofit, install a V-shaped baffle, and adjust the opening angle of the V-shaped baffle to realize the continuous adjustment of the fan-shaped spray head slot angle within a certain range, so that the fan-shaped spray angle can be continuously adjusted within a certain range

The invention discloses a fan-shaped spray head and a spraying method which can change the spray angle by adjusting the groove angle, relates to the technical field of agricultural plant protection machinery, and comprises a spray head body and a V-shaped baffle; the V-shaped baffle can be embedded in the top groove of the spray head body horizontally The distance between the two hooks on the outside of the V-shaped baffle is the same as the distance between the centers of the two circular through holes on the top of the nozzle body. The invention is simple in structure and small in volume, and can realize the continuous variable cutting angle of the fan-shaped nozzle within a certain range, and then realize the continuous adjustment of the spray angle of the fan-shaped nozzle within a certain range, so that it can quickly and accurately perform precise target spraying , so that the drug solution can cover the target to the greatest extent, and improve the utilization rate of pesticides.
Description
technical field [0001] The invention relates to the technical field of agricultural plant protection machinery, in particular to an agricultural plant protection fan-shaped nozzle which can change the spray angle by adjusting the angle of the cutting groove. Background technique [0002] Crops are threatened by diseases, insect pests and weeds during the growth process, and the yield and quality of agricultural products are seriously affected. The control methods of agricultural diseases, insect pests and weeds mainly include physical control, chemical control, biological control and comprehensive control. Chemical control has the characteristics of high timeliness and high efficacy, especially for the effective and timely control of sudden and large-scale outbreaks of pests and weeds. Therefore, it is still the most effective and commonly used plant protection method at present. In plant protection machinery, spherical fan nozzles are generally used. The main structural p...
