Problems solved by technology

However, this is difficult to achieve because the diameter of the disc, the speed of rotation or revolutions per minute (RPM), and the resulting surface tension all affect the atomization process
As a result, the desired droplet size may not be achievable for the desired application rate, resulting in one or more of the following problems: a wide distribution of droplet sizes, wrong application rates, and persistent The energy required to apply the spray fluid is too high for operation
It is worth noting that overland sprinklers also suffer from overly wide droplet size distribution and wrong application rates

Embodiment Construction

[0048] figure 1 An example of a disc 10 for a rotating disc liquid atomizer is shown. The surface 20 of the disc comprises a plurality of concentric rings 30 having different radii and centered on the center of the disc. The surface of the first concentric ring 40 in the adjacent pair of concentric rings is configured to have a first adhesion level to the liquid, and the surface of the second concentric ring 50 in the adjacent pair of concentric rings is configured to have a second adhesion level to the liquid. Level. The first attachment level is lower than the second attachment level.

[0049] In this way, a disk for a rotating disk liquid atomizer or liquid spray unit is provided wherein the droplet distribution range is controlled by varying how the liquid interacts with the surface of the disk as it traverses across the surface of the disk. This enables control of the manner in which the liquid breaks off on or at the periphery of the disk, which is different from the...

Abstract

The invention relates to a disc (10) for a rotating disc type liquid atomizer. The surface (20) of the disc comprises a plurality of concentric rings (30) having different radii, the concentric rings (30) being centered on the center of the disc. A surface of a first concentric ring (40) of an adjacent pair of concentric rings is disposed to have a first adhesion level to liquid. A surface of a second concentric ring (50) of an adjacent pair of concentric rings is disposed to have a second adhesion level to the liquid, where the first adhesion level is lower than the second adhesion level.

Description

technical field [0001] The invention relates to a pan of a spray unit, to a spray unit having such a pan, to a vehicle having at least one such pan, and to a vehicle having such a spray unit. Background technique [0002] The general background of the invention is the application of herbicides and insecticides to crops. The spray liquid must be atomized. This is usually accomplished using hydraulic nozzles. A more sophisticated spraying method uses a rotating disc. When the herbicide / pesticide spraying vehicle is a drone or unmanned aerial vehicle (UAV), its dedicated spraying technology needs to be carefully considered because of the increased weight and energy consumption of the vehicle. The rotating disk is expected to be an effective atomization system for drones. The reason is that the energy required to generate the droplets from the spinning disk is generally low, and the other components are compatible with battery-powered drones. [0003] In general, rotating d...
