DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

It is to be understood that when an element is referred to as being "connected" or "connected" to another element, it may be directly connected or connected to the other element, . On the other hand, when an element is referred to as being "directly connected" or "directly connected" to another element, it should be understood that there are no other elements in between.

Fig. 1 is a perspective view of an apparatus for spraying an apparatus 100 for forming a surface droplet, and Fig. 2 is a plan view of Fig. 3 is a side view of Fig. 1. Fig.

Referring to Figs. 1 to 3, a description will be given of a spraying apparatus 100 for forming a surface droplet of the present invention.

The apparatus 10 for spreading an apparatus for forming a surface droplet of the present invention includes a spreader 10, reflectors 20, 20a and 20b, an angle plate 30 and a fixture assembly 40. [

The mimetic agent used in the present invention may be, for example, methyl salicylate (CAS No. 119-36-8). The mimetic agent may also be a liquid or gas, and may also be a chemical agent.

The sprayer 10 may include a tank 13 capable of storing the simulating agent and a nozzle 17 capable of spraying the simulating agent forward.

The spreader 10 sprays the simulated agent stored in the tank 13 forward through the nozzles 17 provided at the front end in the form of micrometer-sized liquid particles.

The sprayer 10 can be, for example, a superfine electrodrug sprayer having a spraying distance of 12 m, a capacity of the chemical tank of 7 (L), a maximum spraying amount of 60 (L) It can be sprayed with an injection particle size of 30 (占 퐉). However, the spreader 10 of the present invention is not limited to the ultrafine electrodrug spreader of the feature described above, and may be a mist generator, a superfine drug spreader, or a fine-particle drug spreader.

The reflector 20 is rotatably connected to the stationary assembly 40 so as to aggregate the simulated agent sprayed by the sprayer 10 and reflect it to the surface of the earth. In particular, the reflector 20 reflects the liquid chemical to the surface and enables dropping in the form of a droplet. To this end, the reflection plate 20 is formed to form an angle with the ground surface, and the reflection plate 20 can be rotated and fixed by the angle plate 30, which will be described later, so that the angle with respect to the ground surface can be adjusted.

As the reflector 20 forms an angle close to the perpendicular to the ground surface, the droplet of droplet that is sprayed is well formed and agglomerated by the droplet sprayer. As the distance between the reflector 20 and the ground surface becomes closer to each other, The size of the droplet to be dropped becomes small because it is not well formed. By adjusting the angle of the reflection plate 20, the size of the droplet can be adjusted, thereby controlling the moving speed of the droplet.

The reflector 20 includes a reflective surface 22 that coheres and reflects the mimetic agent, a side surface 25 that is connected to the fixture assembly 40, and a receiving portion (not shown) that is configured to receive a portion of the liquid chemical 28a, 28b.

Since the reflection plate 20 is shown in Figs. 4A and 4B, the detailed structure will be described later.

The angle plate 30 rotatably guides the reflector 20 to allow adjustment of the angle between the reflector 20 and the surface of the earth. The angle between the reflection plate 20 and the ground surface is adjusted by the angle plate 30 so that the droplet state of the simulated agent can be adjusted. The droplet state may include the injection amount and the size of the liquid particle.

The fixing assembly 40 is configured to combine configurations of the spatterer 10, the reflector 20, and the angle plate 30 and the like. In addition, the fixed assembly 40 can be mounted on the front of the vehicle, in which case the spreading device 100 for surface-surface droplet formation is moved by the moving vehicle, and the simulated agent can be sprayed on the ground surface.

The fastening assembly 40 may include a base portion 43 to support the weight of the combined configurations and a plurality of engagement portions. The base portion 43 is made of steel or wood to support the weight of various components, and on the other hand, it can be sprayed on the vehicle while moving by a vehicle moving at a constant speed. The plurality of joining portions are structures in which the spreader 10, the reflecting plate 20, the angle plate 30 and the collecting tube 53 are combined with each other and are made of a thin plate material to enable the joining of the spreader 10, the reflector 20, .

The apparatus (100) for generating a surface droplet of the present invention may further include a recovery unit (50). The recovery unit (50) is configured to recover the agglomerated agitator agent in the reflection plate (20). The collection portion 50 allows a portion of the mimic agent to be recycled while preventing the mimic agent from being oversprayed or too large particles being formed.

The recovery unit 50 may include a recovery cylinder 53, a hose 55, and a flange unit 57.

The recovery cylinder 53 is coupled to the fixing assembly 40 and is configured to receive the simulated agent recovered from the reflection plate 20. [

The hose 55 is connected to the collection box 53 and the reflector 20 so that a part of the simulated agent agglomerated in the reflector 20 can be moved to the collection box 53. The hose 55 may be coupled to the receiving portions 28a and 28b of the reflection plate 20 to be described later and the hose 55 is provided in the receiving portions 28a and 28b to allow movement of the simulating agent through the hose 55. [ A hole may be formed.

The flange portion 57 is formed at one end of the recovery tube 53 and has a plate shape for coupling the recovery tube 53 to the fixing assembly 40.

FIG. 4A is a perspective view of one embodiment of the reflection plates 20a and 20b of FIG. 1, and FIG. 4B is a perspective view of another embodiment of the reflection plates 20a and 20b of FIG. The overall characteristics of the reflection plate 20 have been described above. In the following, the detailed configuration and function of the reflection plate 20 will be described with reference to FIG.

The reflectors 20, 20a and 20b may include a reflecting surface 22, a side surface 25 and receiving portions 28a and 28b.

The reflecting surface 22 is a surface that coheres the simulated agent injected through the spreader 10 and reflects it to the ground surface. As the reflector 20 is rotated by the angle plate 30, the angle of the reflecting surface 22 with respect to the ground surface can be changed, thereby changing the droplet state of the simulating agent. The reflecting surface 22 reflects the liquid chemical to the surface and enables dropping in the form of droplets.

The side surface 25 of the reflection plate 20 may be configured such that one side thereof is rotatably connected to the fixing assembly 40 and the other side thereof is connected to the angle plate 30. As will be described later, the angle plate 30 may include a guide portion, and the other side of the side surface 25 of the reflection plate 20 is guided by the guide portion and rotatable about one side.

The receiving portions 28a and 28b are configured to receive the simulated agent from below the reflectors 20, 20a and 20b, and may protrude in the shape of a letter 'A'. As a result, the ends of the reflecting surface 22 and the receiving portions 28a and 28b connected to the reflecting surface 22 are seen as a 'C' shape as a whole. Although an example of the accommodating portions 28a and 28b protruding in an 'a' shape is shown in the drawing, the accommodating portions 28a and 28b may be formed in various shapes to accommodate the mimetic agent and may be formed in a shape such as 'g' .

The accommodating portions 28a and 28b may be provided in two and the two accommodating portions 28b may be formed spaced apart from each other at the center portion of the lower end of the reflector 20b. As a result, a part of the simulated agent agglomerated in the reflector 20b can be moved to the space between the two receptacles 28b to be recovered to the amount of the mimic agent sprayed on the earth surface or to the collection part 50 The amount of simulant can be controlled.

In the present invention, the accommodating portions 28a are formed as one and formed at the lower end of the reflector, and the accommodating portions 28b are formed as two spaced apart from each other at the lower end central portion of the reflector. The reflection plate 20a includes a single receiving portion 28a and the reflection plate 20b includes two receiving portions 28b. The reflector 20 is collectively referred to as the reflector 20a or 20b.

A part of the simulated agent contacting the reflecting surface 22 may be reflected to the surface of the earth and a part of the simulated agent may flow down to be received in the receiving portions 28a and 28b.

On the other hand, a hole is formed on one surface of the accommodating portions 28a and 28b, and a hose 55 of the recycling portion 50 is connected to the hole, so that a part of the simulating agent is stored in the recycling cylinder 53, do.

Fig. 5 is a conceptual view showing the angle plate 30. Fig. With reference to Fig. 5, the structure of the angle plate 30 will be described.

The angle plate 30 is formed as a plate having a generally curved shape as shown in Fig. For example, the angle plate 30 may be formed in the shape of an arc so that an angle guide portion 35 described later is formed. However, the shape of the angle plate 30 is not limited to this, and may be a plate having various cross-sectional shapes in which an angle guide portion 35 described later can be formed therein.

The angle plate 30 is fixed to the stationary assembly 40 on one side. 5, the reflection plate 20 is connected to the other side of the angle plate 30 to guide the reflection plate 20 to enable rotation of the reflection plate 20.

The angle plate 30 may include an angle guide portion 35. The angle guide portion 35 may be formed to be cut so as to guide the reflection plate 20 into the angle plate 30. The angle guide portion 35 is curved inward and outward so that the reflection plate 20 can be rotated at a predetermined rotation radius. 5 shows an example in which the radius of rotation of the reflection plate 20 is R250, the radius of the inner curved surface is R244, and the radius of the outer curved surface is R256.

It is preferable that both ends of the angle guide portion 35 are rounded so as to receive a fixing bolt connecting the reflector 20 to the angle guide portion 35.
