It is AA line sectional drawing, FIG. 5 is the enlarged view of the B part of FIG. 3, FIG. 6 is a figure which shows the state in which the long distance blower tube which concerns on this invention was mounted in the vehicle.

As shown in the drawing, the long-distance blower according to the present invention is connected to the blower 10 including the engine 20 and the impeller 30 mounted on the control unit, and allows the wind generated by the blower 10 to pass therethrough. It serves to spray. And the circumference of the wind discharge side of the blower tube according to the present invention is provided with a plurality of drug supply nozzles (40) connected to the drug tank for pumping and supplying the drug to the wind discharge side through the pumping, the injection supply from the drug supply nozzle (40) The chemical agent is mixed with the wind which is ejected and injected from the inside of the blower pipe and is sprayed further together with the wind.

Therefore, the long-distance blower tube according to the present invention includes a venturi tube-shaped first blower tube 1 connected to the wind generated by the blower 10 and a second air blower connected to the wind discharge end of the first blower tube 1. A blower tube 2 and an outside air inlet 3 formed between the first blower tube 1 and the second blower tube 2 are included.

The first blower pipe 1 according to the present invention is connected to the blower 10 as shown in FIGS. 1 to 4, and has a large diameter of the wind inlet end connected to the blower 10. The farther from the wind inlet end, the smaller the diameter is configured in the shape of the venturi tube. That is, the first blower tube 1 is formed such that the diameter of the wind inlet end through which the wind flows from the blower 10 is large and the diameter of the wind discharge end through which the wind is discharged is smaller than the wind inlet end.

Therefore, since the first blower tube 1 is configured in the shape of a venturi tube, the wind flowing from the wind inlet end of the first blower tube 1 is the wind inside the first blower tube 1 and the first blower tube 1. The wind speed is increased through the venturi effect while passing through the discharge end. Therefore, there is an advantage that the wind discharged from the second blower tube 2 can be reached to a long distance.

In addition, the circumferential plate 1a formed around the first blower tube 1 is formed in a curved shape so that the middle thereof protrudes inward. As a result, a central curvature surface 11 is formed on the inner circumferential surface of the first blower tube 1. Therefore, the inner circumferential surface of the first blower pipe 1 through which the wind flows from the blower 10 is formed as a centrally reduced curved surface 11 to allow the wind to pass through the inside of the first blower pipe 1 with minimum resistance. .

Meanwhile, the first blower tube 1 further includes an inlet horizontal tube 12 that extends horizontally around the wind inlet end of the first blower tube 1. The impeller 30 constituting the blower 10 is disposed inside the inflow horizontal pipe 12. Therefore, as the inlet horizontal pipe 12 having the impeller 30 of the blower 10 disposed therein is further formed at the wind inlet end of the first blower pipe 1, the assembly of the blower 10 and the blower pipe can be easily performed. It can be done. In addition, by providing the impeller 30 constituting the blower 10 in the first blower tube 1, the speed of the wind blown through the impeller 30 a little faster to speed up the injection speed of the wind There is an advantage to this.

In addition, the second blower tube 2 according to the present invention is connected to the wind discharge end of the first blower tube 1, as shown in Figures 1 to 4, the wind discharge of the first blower tube (1) The diameter of the wind inlet end connected to the end is smaller and farther away from the wind inlet end, the diameter becomes larger and becomes smaller again.

That is, the circumferential plate 2a formed around the second blower tube 2 is formed in a curved shape so that the middle thereof protrudes outward, and the inner circumferential surface of the second blower tube 2 has a curved nose face if the center is extended (21). Coanda surface is formed.

Therefore, as the inner circumferential surface of the second blower pipe 2 for injecting wind is formed as a curved nose facet 21 with an extended center, the wind introduced into the second blower tube 2 is curved nose facet 21. By moving close to, the wind speed is reduced and the wind blowing distance is increased. In addition, by expanding the center of the inner circumferential surface of the second blower tube 2, the outside air introduced from the outside may be expanded and collected in the second blower tube 2 to increase the air volume of the sprayed air.

In other words, by forming a curved coplanar face 21 with a center extending on the inner circumferential surface of the second blower tube 2, the wind introduced into the second blower tube 2 is curved by the Coanda effect. It is injected while moving near the 21. Therefore, the wind injected from the second blower tube 2 is to be longer the injection distance due to the coanda effect of the curved coplanar face 21. Therefore, the long-distance blower of the present invention has an advantage of allowing a longer blowing distance of the wind through the Venturi effect generated in the first blower pipe 1 and the Coanda effect generated in the second blower pipe 2. .

The second blower tube 2 includes a discharge horizontal tube 22 extending horizontally around the wind discharge end of the second blower tube 2 and a wind guide vane 23 provided in the discharge horizontal tube 22. More).

On the other hand, it is preferable that the first round part 5 is formed at the inner part of the inner circumference where the second blower tube 2 and the second vertical ring 44 meet to guide the outside air into the inside of the second blower tube 2. . As such, the first round part 5 is formed around the wind inlet end of the second blower tube 2 so that the vacuum is applied to the inner space of the first round so that the outside air can be introduced more stably. That is, since the vacuum state is continuously formed in the process of operating the blower 10 inside the first round part 5, the outside air is introduced more stably.

In addition, the connection of the first blower tube 1 and the second blower tube 2 of the long-distance blower tube according to the present invention, as shown in Figures 4 and 5, the first blower tube 1 and the second blower tube (2) In order to connect the outside air inlet (3) is formed between the outside air inlet (3). That is, the connection outside air inlet part 4 serves to form the outside air inlet 3 together while interconnecting the first blower pipe 1 and the second blower pipe 2.

A right angle portion 43a is formed at an inner side of an inner circumference where the first blower tube 1 and the first vertical ring 41 meet. Therefore, the right angle part 43a serves to guide the outside air introduced into the second blower tube 2, and minimizes the inflow of outside air into the first blower tube 1.

A first horizontal ring 42 is further formed around the outer circumference of the first vertical ring 41 in the direction of the first blower pipe 1, and the first vertical ring 41 and the first horizontal ring are further formed. A second round portion 43 is formed at an outer portion of the outer circumference where the 42 meets, and horizontally in the direction of the second blower tube 2 at the outer circumference of the second vertical ring 44. The second horizontal ring 45 is further formed, the third round portion 46 for guiding the inflow of outside air to the outer portion of the outer circumference where the second vertical ring 44 and the second horizontal ring 45 meets Is formed.

Accordingly, a second round portion 43 is further formed at an outer side where the first vertical ring 41 and the first horizontal ring 42 meet each other, and the second vertical ring 44 and the second horizontal ring 43 are formed. By forming a third round portion 46 for guiding the inflow of the outside air to the outer side where the ring 45 meets, the inflow of the outside air can be made more smoothly.

In addition, the connection part 47 includes a plurality of assembly holes H formed at positions facing each other with the first vertical ring and the second vertical ring 44. In addition, the connection part 47 is fitted at each position where the assembly hole H is formed between the first vertical ring 41 and the second vertical ring 44 and is assembled to correspond to the assembly hole H therein. It includes a plurality of spacer 471 in which the hole (H) is formed.

Therefore, the connecting portion 47 is formed by integrally forming the spacer 471 provided between the first blower tube 1 and the second blower tube 2 to the first vertical ring 41 or the second vertical ring 44. You can also configure it more simply.

The spacer 471 may further include a streamlined surface 471a that is formed at both sides and has a curved outer side of the middle to reduce inflow resistance of the outside air. Therefore, by forming the streamlined surface 471a on both sides of the spacer 471, the outside air may flow more smoothly between the first and

second blower pipes

1 and 2.

Meanwhile, the outside air inlet 3 may adjust the width of the outside air inlet 3 by adjusting the width of the spacer 471. Therefore, if the wind flows back after the assembly of the first blower pipe 1 and the second blower pipe 2 or the performance is insufficient, by adjusting the width of the outside air inlet port 3, the problem of wind backflow can be solved. And there is an advantage to improve the blowing performance.
