Korean Patent Publication No. 10-1348885 discloses a method of controlling the amount of water particles contained in a cleaning liquid flowing into a hollow tube by rotating a hollow tube which is located on an upper part of a cleaning tank in which a cleaning liquid is stored, And an air flow path in which the air blown by the operation of the blowing means mounted on the rear mounting portion flows toward the front discharge portion side, the spraying means having an outer housing for spraying the water particles upward, And a connecting portion connecting the main body and the spray discharge portion of the outer housing to enable air communication; Further comprising a separating cylinder which is provided in the control tank so as to surround the hollow tube and in which a plurality of water holes communicating with the control liquid are formed at a lower portion thereof so that water particles sprayed through the spray discharging portion of the outer housing move along the connecting portion Joined to the air flow path of the main body and discharged to the outside through the discharge portion; There is disclosed an ultrafine particle sprayer for house agriculture, in which a stirring blade for stirring the solution in the inside of the separator is provided on the lower outer side of the hollow tube.

Korean Patent Registration No. 10-1348892 discloses a method of increasing the amount of the cleaning liquid along the inner surface of the suction pipe by rotating a suction pipe that is submerged in the cleaning liquid of the storage container by driving a rotary motor, There is provided a centrifugal sprayer comprising spraying means having an outer housing provided with a spray discharge portion for spraying particles of a control solution of fine particles formed by collision with a metal frame.

The detergent disclosed in the above-mentioned patent documents is a centrifugal atomizer and has a structure in which an atomizing unit for atomizing the control solution into the mist of super-fine particles is installed vertically upward.

In this case, referring to FIG. 1 of the second patent document, a centrifugal atomizer having a vertical upward spray structure has to be provided with a guide means such as a duct for spraying spray mist horizontally.

However, during the movement of the fog along the guide means, the fog particles became larger due to the accumulation of fog, which decreased the spraying efficiency of the sprayer.

As the size of the sprayer increases due to the guide means such as a duct, the movement path for moving the sprayer within the house has to be increased. This has resulted in a reduction in the efficiency of house cultivation due to the relatively reduced size of the crop growing space in the house.

When the mist is horizontally installed in order to spray the mist in the horizontal direction, there is a problem that the mist can not be supplied smoothly to the spray of the cleaning solution.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

According to the present invention, a particulate matter sprayer for house agriculture is provided with a reservoir 10 for storing a control solution, and a front part (not shown) located at an upper part of the reservoir 10 and including a motor A motor housing 20 in which the rotating shaft 20a of the motor is exposed to the outside and a fastening housing 40 which is coupled to the rotating shaft 20a of the motor exposed to the outside with the sealing member 30 interposed therebetween do.

The reservoir (10) is provided with a pumping motor (12) for supplying the control liquid to the outside. The pumping motor 12 may be installed inside or outside the reservoir 10 if it can be operated to supply the control liquid to the outside of the reservoir 10.

The motor housing 20 is positioned above the reservoir 10 so that the rotary shaft 20a can be installed in a horizontal direction. The rotating shaft 20a is installed horizontally in order to spray the mist of the fine particles formed from the atomizing portion coupled to the rotating shaft 20a in the horizontal direction.

As shown in FIG. 2, a protective cover 24 is installed on the upper portion of the motor housing 20 to block the fog from entering the electric field.

As shown in the photographs of Figs. 4 and 5, the sealing member 30 is formed so that a through hole through which the rotation shaft 20a of the motor passes is formed at the center, and a plurality of projections are formed concentrically with the through holes And a second circular plate member 34 having a plurality of projections formed concentrically so as to be able to engage with the first circular plate member 32 and the first circular plate member 32 and having a through hole through which the rotary shaft passes, . When the first disc member 32 and the second disc member 34 are engaged with each other, the protrusions of the first disc member 32 are held between the protrusions of the second disc member 34, A plurality of closed curves are formed inside the sealing member (30).

The fastening housing 40 includes a fastening portion 42 to be directly engaged with the rotary shaft 20a, a main body 44 to be engaged with the fastening portion 42 and a fastening portion 46 to be fastened to the main body 44. A sealing member 30 is provided between the engaging portion 42 and the main body 44 to engage with the rotation shaft 20a of the motor exposed through the engaging portion 42 and a motor protecting plate 26 ).

In the interior of the fastening housing 40, a receiving space for receiving the control liquid supplied from the reservoir 10 is formed. On the side wall of the coupling housing 40, a discharge port (not shown) through which the cleaning liquid accommodated in the accommodation space is discharged is formed. A flow space portion formed between the accommodation space and a pair of rotation plates described below is communicated through the discharge port.

The particulate matter sprayer for house agriculture according to the present invention includes a pair of rotary plates 50 which are separated from each other by a predetermined distance on the outer side of a coupling housing 40 and a metal frame assembly 60 , And a supply pipe (70) for connecting the pumping motor (12) and the fastening housing (40) so as to supply the control liquid.

The pair of rotary plates 50 is positioned between the main body 44 of the fastening housing 40 and the fastening portion 46 and is spaced apart by the spacers 52 at a predetermined interval. The space between the pair of rotary plates 50 acts as a flow space portion in which the cleaning liquid flows.

As shown in the photograph of FIG. 6, the metal frame assembly 60 includes a pair of donut-shaped circular plates 62 and 64 spaced apart from each other by a predetermined distance, and a plurality of metal frames 62 and 64 connecting the outer edges of the donut- (66). The metal frame 66 can be manufactured, for example, by forming a plurality of slit holes in a metal plate.

The atomizing portion forming the fog of the fine particles may be composed of a pair of rotary plates 50 and the metal tassel assembly 60.

Reference numeral 80 is an outer housing surrounding the motor housing 20 and the atomization portion. One opening of the outer housing 80 is a spray outlet for spraying the mist of the fine particles generated in the atomizing unit and the other opening is an air inlet for introducing outside air. An air blower (not shown) for forcibly injecting outside air may be installed at the other opening of the outer housing 80.

Since the one opening portion and the other opening portion of the outer housing are located along the longitudinal direction of the rotary shaft 20a, the outside air introduced through the other opening portion flows horizontally toward the one opening portion. It is possible to reduce the possibility that the fog of the fine particles formed in the atomization portion is in contact with the inner surface of the outer housing when the mist flows along the flow direction of the outside air, thereby relatively reducing the accumulation of mist, It does not require a member.

Reference numeral 90 is an impeller coupled to the fastening portion 46 of the fastening housing 40. When the rotary shaft 20a rotates and the fastening housing 40 rotates, the impeller 90 rotates to introduce air into the interior of the metal tee assembly 60.

Hereinafter, the operation of the particulate sprayer for house agriculture according to the present invention will be described.

In the particulate matter sprayer for house agriculture according to the present invention, when the rotary motor installed in the motor housing 20 operates to rotate the rotary shaft 20a, the coupling housing 40 coupled to the rotary shaft 20a is engaged The rotary plate 50 coupled to the fastening housing 40 is engaged.

Further, when the pumping motor 12 is operated, the control liquid in the reservoir 10 is supplied to the accommodating space of the fastening housing 40 through the supply pipe 70. [

The control liquid supplied to the receiving space of the fastening housing 40 moves along the flow space between the rotating plates 50 through the discharge port formed in the side wall of the fastening housing 40, The mist of the particulate is discharged to the outside through the spray outlet of the outer housing 80. [

The inflow amount of the control liquid flowing into the receiving space of the fastening housing 40 is determined by the operation of the pumping motor 12 regardless of the rotation speed of the rotary shaft 20a. That is, by the operation of the pumping motor 12, a relatively large amount of the control liquid flows into the accommodating space of the fastening housing 40, so that the water pressure of the control liquid increases in the accommodating space.

A sealing member having a special structure is required in order to prevent the control liquid from flowing into the electric field portion of the motor housing 20 through the rotary shaft 20a of the rotary motor. The sealing member 30 according to the present invention can satisfy this requirement. That is, a plurality of closed curved lines are formed in a state where the first circular plate member 32 and the second circular plate member 34 of the sealing member 30 are engaged with each other, and such closed curves are formed in such a manner that the cleaning liquid in the receiving space flows into the rotary shaft 20a It is enough to prevent. Further, the sealing member 30 having a plurality of closed curves prevents the lubricant around the rotating shaft 20a from being discharged to the receiving space.

When the fan installed at the other opening of the outer housing 80 is operated, the inflow amount of the outside air flowing into the inside of the outer housing 80 increases, and the spray efficiency of the fog of the fine particles generated in the atomizing portion is discharged to the spray outlet Can be improved.

When the external air is introduced into the inside of the assembly 60 by the rotation of the impeller 90 or the operation of the fan and the fog of the fine particles formed in the atomization portion is sprayed through the spray outlet, It is confirmed that the spray distance increases when a pair of donut-shaped discs 62 and 64 are included, compared to the case where one donut-shaped disc is included. That is, in the case of including a pair of donut-type disks, it was confirmed that although the exact mechanism was not understood, the spray efficiency was improved.

It is to be understood that the foregoing is only illustrative of the preferred embodiments of the present invention and that those skilled in the art will be able to make modifications and alterations to the present invention without departing from the scope of the appended claims.
