  Another object of the present invention is to provide an ultrafine particle control machine for house agriculture that can effectively spray the control liquid with water particles in an ultrafine state while the control tank in which the control liquid is stored moves. The purpose is to provide

  In order to achieve the above object, according to the present invention, the hollow tube which is located in the upper part of the control tank in which the control liquid is stored and is immersed in the control liquid of the control tank is rotated. A control apparatus including a spraying means having an outer housing provided with a spray discharge part for changing the control liquid flowing into the hollow tube into water particles and spraying the water particles is provided in the spray discharge part of the external housing. The air is blown forward by the operation of the air blowing means mounted on the rear mounting portion, and is connected to the connecting portion having one end connected to the other end of the connecting portion so that air can pass without any stagnation. A duct composed of a main body having an air flow path that flows toward the discharge portion side; a plurality of water passage holes that are provided in the control tank so as to surround the hollow tube and allow the control liquid to pass through without stagnation. Formed at the bottom And water particles sprayed through the spray discharge part of the external housing move along the connecting part, and then join the air flow path of the main body and are discharged to the outside through the discharge part.

  While the control tank moves, the control liquid stored in the control tank is swung or even if the control tank is tilted, the control liquid can be effectively sprayed.

  Since the control solution is sprayed in the form of ultrafine water particles, the amount of drug used can be reduced.

1 is a view illustrating a control machine according to the present invention.

  Hereinafter, a configuration and operation of a control machine according to the present invention will be described with reference to the accompanying drawings.

  First, the control machine 100 rotates a control tank 110 in which a control liquid is stored, and a hollow tube 122 provided on the control tank 110 and immersed in the control liquid stored in the control tank 110. And spraying means 120 for spraying the control liquid flowing into the hollow tube 122.

  The spraying means 120 has an outer housing 121 having a predetermined shape whose upper and lower portions are open. The upper part of the outer housing 121 is provided with a spray discharge part 121a from which ultrafine water particles are discharged, and the lower part is provided with an air inflow part 121b into which external air is introduced. At this time, the rotary motor 126 is provided on the seat 126b inside the outer housing 121, and a rotating shaft 126a projects downward from the lower portion of the motor 126. A through hole that penetrates the rotating shaft 126a in a rotatable state is formed. Reference numeral 125 denotes a motor lid that protects the rotary motor 126. A flow space in which water particles flow is formed between the inner surface of the outer housing 121 and the outer surface of the motor lid 125.

  A hollow tube 122 is coupled to the lower portion of the rotating shaft 126a exposed through the through hole of the seating platform 126a, and the hollow tube 122 extends so as to be immersed in the control solution of the control tank 110. To do. When the rotary shaft 126a is rotated by the operation of the rotary motor 126, the hollow tube 122 is also rotated.

  The outer surface of the hollow tube 122 is provided with a first rotating plate 128a and a second rotating plate 128b that are spaced apart from each other by a predetermined interval. The space between the rotating plates 128a and 128b is rotated by the rotating plates 128a and 128b. During this time, the control liquid that has flowed in through the hollow tube 122 forms a flow space that can flow to the outside by centrifugal force. Further, an impeller 124 is provided at an intermediate portion of the hollow tube 122 corresponding to an upper position separated from the surface of the control liquid of the control tank 110, and a metal frame having a large number of slits at the end of the flow space portion. 129 is provided.

  In the rotary disk type spraying means 120 having the above-described configuration, when the rotary motor 126 operates and the rotary shaft 126a rotates, the hollow tube 122 connected to the rotary shaft 126a starts to rotate. As a result, the first rotating plate 128a and the second rotating plate 128b provided on the upper portion of the hollow tube 122 rotate.

  When the pressure around the rotating shaft 126a is reduced by the rotation of the first rotating plate 128a and the second rotating plate 128b, the control liquid stored in the control tank 110 moves upward along the inner surface of the hollow tube 122. After that, the centrifugal force generated by the rotation of the rotating first rotating plate 128a and the second rotating plate 128b flows along the flow space between the first rotating plate 128a and the second rotating plate 128b. .

  The control liquid discharged to the end of the flow space portion forms fine ultrafine water particles while colliding with the metal frame 129, and such water particles pass through the slits of the metal frame 129. It becomes like this.

  On the other hand, when the impeller 124 provided at the intermediate portion of the hollow tube 122 starts rotating, the external air flows into the external housing 121 through the air inflow portion below the external housing 121 and then sprays on the top of the external housing 121. It moves to the discharge part 121a side. A filter 123 for preventing foreign matters such as insects from entering the air inflow portion of the external housing 121 through the air inflow portion of the external housing 121 is provided.

  The water particles that have passed through the slits of the metal frame 129 join the movement of the external air that has flowed into the external housing 121 by the rotation of the impeller 124 and are discharged through the spray discharge portion 121a at the top of the external housing 121.

  According to the present invention, the control device 100 further includes a duct 160 including a connecting portion 166 whose one end is coupled to the spray discharge portion 121 a of the outer housing 121. The duct 160 has a main body 160a to which the other end of the connecting portion 166 is coupled. A mounting portion to which the air blowing means 180 is mounted is provided at the rear of the main body 160a, and air is discharged to the front of the main body 160a. A discharge unit 164 is provided. The duct 160 has a generally “Y” structure so that the water particles described below can smoothly flow into the main body 160 a side of the duct 160.

  Inside the main body 160a, an air flow path is provided through which air blown by the operation of the blowing means 180 flows toward the discharge section 164. The air blowing means 180 may be manufactured with a structure in which a fan is attached to the end of the drive shaft of the drive motor.

  The duct 160 can be manufactured to have a structure that is adjustable in angle in the vertical direction with respect to the spraying means and is rotatable in the horizontal direction. This is for adjusting the spraying direction of the water particles discharged through the discharge unit 164. For example, one end of the connecting portion 166 of the duct 160 can be attached to the spray discharge portion 121a of the external housing 121 so as to be horizontally rotatable, and the other end of the connecting portion 166 is the main body of the duct 160. 160a can be coupled to adjust the angle in the vertical direction.

  As described above, the water particles formed in the spraying means 120 and discharged through the spray discharge part 121a of the external housing 121 flow to the main body 160a side of the duct 160 via the connecting part 160 of the duct 160, and then blown. Together with the air blown by the operation of the means 180, the air flows along the air flow path of the main body 160a toward the discharge part 164 side. As a result, the water particles in the form of ultrafine mist that have passed through the slits of the metal frame 129 are sprayed to the outside by the operation of the blowing means 180.

  Reference numeral 170 denotes a control unit that controls the operation of the rotary motor 126 and the air blowing unit 180, and adjusts the particle size and spray amount of water particles generated from the spray unit 120 by the control operation of the control unit 170, and the discharge unit The spray distance of the water particles discharged through 164 is adjusted. For example, when the rotational speed of the rotary motor 126 is increased, not only the amount of the control liquid flowing into the hollow tube 122 is increased, but also the impact force that collides with the metal frame 129 is increased, thereby causing water particles. The particle size becomes fine. In addition, when the driving speed of the driving motor of the blowing unit 180 is increased, the air blowing force is increased and the spray distance of the water particles discharged through the discharge unit 164 is increased.

  According to the present invention, the control device 100 is provided in the control tank 110 so as to surround the hollow tube 122, and has a cylindrical shape in which a plurality of water inlets 130a through which the control solution can pass without a stagnation are formed. A separation tank 130 is further included. The separation tank 130 reduces shaking of the control liquid while the control machine 100 moves, and prevents the control liquid from contacting the impeller 124.

  A stirring blade 150 for stirring the control liquid in the separation tank 130 is provided on the lower outer surface of the hollow tube 122. The stirring blade 150 agitates the control solution present in the separation tank 130 while rotating with the rotation of the hollow tube 122 so that the powdered medicine such as agrochemicals and nutrients and water are uniformly mixed.

  On the other hand, when the control liquid sways so much that the separation tank 130 cannot prevent the control liquid from shaking, the swaying control liquid collides with the impeller 124, which reduces the blowing efficiency of the impeller 124. The spraying efficiency is reduced, and the impeller 124 is damaged in a severe case. Therefore, the rocking prevention plate 140 is provided inside the separation tank 130.

  In order to prevent such a phenomenon, the control device 100 according to the present invention is arranged in the center so as to be movable in the vertical direction along the hollow tube 122 according to the water level of the control liquid stored in the control tank 110. It further includes a rocking prevention plate 140 provided in the separation tank 130 in a state where a hole is formed and is floating on the surface of the control liquid.

  The anti-swaying plate 140 is provided in a state of floating on the surface of the control liquid, and prevents the control liquid from swinging while the control tank moves. In other words, while the control tank moves, the control liquid inside the separation tank 130 does not swing by the swing prevention plate 140 even if the control liquid outside the separation tank 130 swings.

  On the other hand, when the control tank 110 is tilted while moving, the control liquid stored in the control tank 110 maintains a flat surface by gravity, and the hollow tube 122 maintains a tilted state with respect to the control liquid plane. To do. This acts as a cause that the control liquid cannot rise smoothly along the inner surface of the hollow tube.

  The swing prevention plate 140 is bent at the flat portion 142 that contacts the surface of the control liquid and the frame of the flat portion 142 so that the control liquid can be smoothly raised even when the control tank 110 is tilted. It consists of a flange portion 144 that contacts the inner surface of the tank. This is because the control tank 110 is inclined and the anti-swaying plate 140 located inside the separation tank 130 is also inclined. As a result, the surface of the control liquid that contacts the flat portion 142 of the anti-swing plate 140 is also inclined. Since the state is maintained, the control liquid rises smoothly along the inner surface of the hollow tube 122.

  The pest controller 100 according to the present invention can be sprayed with a pest control liquid while being moved by being provided in a transfer means equipped with wheels.

  Hereinafter, the operation of the control machine according to the present invention will be described.

  When the rotary motor 126 operates and the rotary shaft 126a rotates, the hollow tube 122 starts to rotate. In conjunction with this, the first rotary plate 128a and the second rotary plate 128b, the impeller 124, and the agitation are mixed. The wing 150 also rotates. The control liquid in the hollow tube 122 immersed in the control liquid by the rotation of the first rotary plate 128a and the second rotary plate 128b rises along the inner surface of the hollow tube 122, and then the first rotary plate 128a and the second rotary plate 128a. It flows along the flow space between the two rotating plates 128b. The control liquid discharged from the flow space collides with the metal frame 129 to form ultrafine water particles, and the ultrafine water particles pass through the slits of the metal frame 129.

  The ultrafine water particles that have passed through the slit flow together with the external air that flows into the outer housing 121 by the rotation of the impeller 124 that rotates together with the hollow tube 122. The water particles are sprayed to the outside through the discharge unit 164 together with the air flowing along the air flow path of the main body 160a of the duct 160 by the operation of the air blowing means 180.

  At this time, while the control tank 110 moves, the control liquid existing outside the separation tank 130 is swung, while the control liquid inside the separation tank 130 is maintained in a state where it is not swung by the swing prevention plate 140.

  Even when the mounting table is tilted, the control liquid existing inside the separation tank 130 is tilted by the anti-swing wave 140 in the same manner as the separation tank 130, while the control liquid outside the separation tank 130 maintains a flat state by gravity. It becomes like this.

  Therefore, according to the present invention, it is possible to improve the spray efficiency of the control liquid even when the control liquid swings while the control tank 110 moves or the control tank is tilted and the control liquid is tilted.

  The foregoing is merely illustrative of a preferred embodiment of the present invention, and those skilled in the art to which the present invention pertains will be aware of modifications and corrections to the present invention without departing from the spirit and scope of the invention as set forth in the claims. You can make changes.
