Problems solved by technology

The pressure atomization nozzle uses the pressure of the liquid itself as kinetic energy to atomize the liquid medicine. It has a simple structure and low cost, but its atomization effect is greatly affected by the load drop, and the droplet penetration is poor, and the droplet size is affected by the liquid. The viscosity has a great influence; although the atomization performance of the pneumatic atomizing nozzle is better than that of the pressure atomizing nozzle, its atomization consumes a lot of air and energy

Embodiment 1

[0019] This embodiment includes a nozzle body 1, a spray sheet 9, pipe joints 3, 4, and a nozzle cap 8. The nozzle body is provided with a nozzle body cavity, and the nozzle body cavity is provided with a shrinkage cavity 8, a throat cavity 6, and an expansion cavity 7. , the nozzle body shrinkage cavity is a platform with a large upper part and a smaller lower part, the nozzle body throat cavity is cylindrical, located below the contraction cavity, the diameter of the cylinder is the same as the diameter of the small end of the contraction cavity, and the nozzle body expansion cavity It is a table shape with a small upper part and a larger lower part. The diameter of the small end is the same as that of the throat cavity. The tail end of the generator is provided with air injection holes 13 arranged in a staggered space, and the air inlet pipe joint 3 for the bubble generator is connected with the nozzle body 1. There is a liquid inlet hole on the side of the nozzle body, and ...

Embodiment 2

[0023] The difference between this embodiment and Embodiment 1 is that the included angle between the central line of the air injection hole on the bubble generator and the axis of the bubble generator of the nozzle body is 50°.

Embodiment 3

[0025] The difference between this embodiment and Embodiment 1 is that the included angle between the central line of the gas injection hole on the bubble generator and the axis of the bubble generator of the nozzle body is 45°.

Abstract

The invention relates to an effervescent atomization medicament applying spray head, which comprises a spray head body, a spray sheet, a pipe joint and a spray head cap, and is characterized in that a contraction cavity, a laryngeal cavity and an expansion cavity are arranged in an inner cavity of the spray head body, wherein a bubble generator is arranged in the spray head body, a liquid inlet hole is arranged on one side of the spray head body, the lower end of the spray head body is connected with the spray head cap, a seal ring is arranged between the lower end of the spray head body and the spray head cap, the bubble generator is linked with the spray head body through a gas inlet pipe joint, gas injection holes which are in staggered spatial arrangement are arranged at the tail end of the bubble generator, the spray sheet is embedded in the spray head cap, a spray sheet pressure block is arranged above the spray sheet, the spray sheet pressure block is in tight fit with the spray head cap, and a liquid inlet pipe is linked with the spray head body through a liquid inlet pipe joint. Compared with the prior art, the effervescent atomization medicament applying spray head has the advantages of improving the applicability to medicament liquid with different viscosities of the plant protection spray head, enabling fog drops to be finer and more uniform, and having better atomization effect.

Description

technical field [0001] The invention belongs to a plant protection spraying device, in particular to a bubble atomization spraying head. Background technique [0002] The sprinkler head is a key component of the plant protection pesticide application equipment, which directly affects the spraying effect of the equipment. At present, the widely used pressure atomizing nozzles and pneumatic atomizing nozzles rely on the large relative speed difference between the atomizing medium and the liquid, mainly to overcome the viscosity of the liquid to atomize the liquid, and the required atomization pressure is relatively large, and the viscosity The bigger it is, the less likely it is to be atomized. The pressure atomizing nozzle uses the pressure of the liquid itself as kinetic energy to atomize the liquid medicine. It has a simple structure and low cost, but its atomization effect is greatly affected by the load drop, and the droplet penetration is poor, and the droplet size is a...
