DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diffuser orifice structure of a sprayer, and more particularly to a sprayer having a blower tube provided in a power sprayer. The present invention relates to a diffusion nozzle structure of a sprayer.

[0002]

2. Description of the Related Art In recent years, equipment used for agricultural work has been increasingly powered, and a power device, for example, an engine-equipped sprayer, has been developed for spraying agricultural chemicals and fertilizers instead of the conventional manual baggage sprayer. I have.

FIG. 10 (a) shows a configuration of a conventional power spreader 1 described in Japanese Utility Model Publication No. 59-17398. In the figure, reference numeral 2 denotes a tank for storing a spraying agent such as agricultural chemicals or fertilizer, 3 denotes an engine, 4 denotes a blower rotated by the engine 3, 5 denotes a blower pipe made of synthetic resin or the like connected to the blower 4, 6 denotes a blower It is a nozzle opened on the lower surface of the blower tube 5. In the power sprayer 1, when the blower 4 is rotationally driven by the engine 3, the spraying agent in the tank 2 is pressure-fed into the blower tube 5 by the wind force generated by the blower 4 and provided on the lower surface of the blower tube 5. The spraying agent is sprayed from the spray nozzle 6 and the tip of the blower tube 5.

FIG. 10 (b) shows an example of the structure of a conventional diffusion guide member 7 provided around the nozzle 6 of the blower tube 5 in order to diffuse the spraying agent from the plurality of nozzles 6 and evenly distribute the agent. It is shown. This diffusion guide member 7 was composed of only one inclined guide plate. Therefore, the spraying agent S that is pressure-fed in the blower tube 5 and that is sprayed from the injection port 6 by the diffusion guide member 7 is diffused in the flow direction of the spraying agent S,
There was not much diffusion on the upstream side of the nozzle 6 and the diffusion area was small.

Therefore, in Japanese Utility Model Publication No. 59-17398, as shown in FIG. 10 (c), a barrier 8a is raised from the downstream edge of the nozzle 6 toward the center of the blower tube 5,
Next, the upper end of the barrier 8a is extended a predetermined length toward the upstream side of the blower tube 5 by the flat portion 8b, and the upstream end of the flat portion 8b is inclined toward the center of the blower tube 5 by the inclined guide portion 8c. A diffusion guide member 8 has been devised. According to Japanese Utility Model Publication No. 59-17398, according to the configuration shown in FIG. 10 (c), the spraying agent S1 that has flowed through the blower tube 5 and hit the inclined guide portion 8c is diffused downstream of the blower tube 5, It is described that since the spraying agent S2 hitting the barrier 8 is reflected and diffused to the upstream side of the blower tube 5, the diffusion angle of the medicine from each nozzle 6 is widened and a good spraying pattern is obtained.

[0006]

However, according to experiments conducted by the present inventor, according to the diffusion guide member 8 described in Japanese Utility Model Publication No. Sho 59-17398, the scattered dust flowing through the air duct 5 and hitting the inclined guide portion 8c was found. The spraying agent S1 is bent in the direction of the upstream side of the blower tube 5 as shown by a dashed line S3 by the spraying agent S2 flowing to hit the barrier 8a, while the spraying agent S2 flowing to hit the barrier 8a is inclined and guided. Since the spraying agent S1 flowing along the plate 8c is diffused to the upstream side of the blower tube 5 as shown by the broken line S4, the diffusion angle of the agent from each nozzle 6 is not widened, and a good spraying pattern is obtained. It turned out that there was no problem.

Therefore, according to the present invention, the spraying agents whose flow paths are changed in different directions by the diffusion guide member do not affect each other, and are spread over a wide range at two or more angles. It is an object to provide a possible spray nozzle structure for the sprayer.

[0008]

In order to achieve the above object, a diffusion nozzle structure of a sprayer according to the present invention, wherein a spraying agent in a tank is fed into a blower tube by wind force from a blower driven by a power unit, In a spraying machine that sprays from a nozzle provided at a predetermined position, a diffusion guide member for a spraying agent is provided around the nozzle, which protrudes toward the inside of the blower tube, and the diffusion guide member is configured to spray the sprayer from an upstream side of the blower tube. A first inclined guide portion that is smoothly inclined toward the tip end of the first inclined guide portion, and is provided adjacent to at least one side of the first inclined guide portion, and has an inclination different from that of the first inclined guide portion. A spraying agent flowing in the first inclined guide and a spraying agent flowing in the second inclined guide are sprayed at two or more angles which are not affected by each other. Characterized in that There.

[0009] The direction of inclination of the second inclined guide portion may be a direction away from the axial direction of the blower tube.

[0010] In the above configuration, a partition wall may be provided between the first inclined guide portion and the second inclined guide portion.

According to the diffusion nozzle structure of the sprayer of the present invention,
Since the second inclined guide portion of the diffusion guide member is provided adjacent to at least one side of the first inclined guide portion, the spreading agent flowing in the first inclined guide portion and the inside of the second inclined guide portion are separated. Since the flowing spraying agent is sprayed at two or more angles that are not affected by each other, the diffusion range is widened.

Further, if the direction of inclination of the second inclined guide portion is set to a direction away from the axial direction of the blower tube, the spraying agent flowing in the first inclined guide portion and the spraying agent flowing in the second inclined guide portion are different. , Spread at two or more angles that are more insensitive to each other. Further, if a partition wall is provided between the first inclined guide portion and the second inclined guide portion, the interference between the spray agent flowing in the first inclined guide portion and the spray agent flowing in the second inclined guide portion is provided. Is further reduced.
