Seed spraying in which fertilizer, water, etc. are added and stirred, and an agglomerate consisting of water and powdered nori material is mixed with the agitated object to be sprayed, and the mixture is sprayed onto an inclined surface and fixed. Regarding machine nozzles.

(Prior Art) Conventionally, most of this type of seed spraying machine feeds the object to be sprayed, which is stirred in a stirring tank, to the spray nozzle via a pump, and also moves the object to be sprayed onto an inclined surface as appropriate. As a fixing agent for reliable fixing, for example, a sticky agglomerate prepared by dissolving an appropriate powdered glue material in water is fed to the spray nozzle via an appropriate pump (for example, a gear pump). This spray nozzle portion is configured to spray the agglomerate and the object to be sprayed at the same time.

(Problem to be Solved by the Invention) However, with the spray nozzle of a conventional seed spraying machine, the agglomerate and the object to be sprayed are simply sprayed at the same time, and the agglomerate does not reach the spray nozzle. It is difficult to mix reliably and sufficiently with the object to be sprayed, and it is also difficult to mix uniformly.

On the other hand, the compressor 30 is driven by the prime mover to feed air into the agglomerate tank 31 to stir the water and powdered paste material in the agglomerate tank 31, and the agitated agglomerates are The agent is delivered to spray nozzle A via hose 32. Then, the object to be sprayed fed to the spray nozzle A moves within the joint body 5 toward the tip of the nozzle body 2. At this time, the agglomerate fed to the spray nozzle A passes through the communication groove 11 from the pipe attachment part 12, further passes through the communication hole 6, and is mixed with the object to be sprayed. Then, when the object to be sprayed mixed with the agglomerate passes through the intermediate nozzle 3,
The mixture is further mixed through the flat opening 3a, and then sprayed linearly through the tip nozzle 4.

(Effects of the Invention) Therefore, the present invention provides a seed spraying machine S that sprays an agglomerate made of water and an appropriate powdered nori material onto a material to be sprayed made of soil, fertilizer, water, seeds, etc. In the spray nozzle A, on the nozzle body 2,
A suitable number of flat openings 3a having a substantially elliptical cross-sectional shape are provided at appropriate intervals along the direction of the cylinder core, and the longitudinal direction of the flat openings 3a in the plane perpendicular to the cylinder center is Since the adjacent flat openings 3a are formed to be appropriately different from each other, when the material to be sprayed mixed with the agglomerate fed from the joint 1 part passes through the intermediate nozzle 3, the flat openings 3a The portion 3a makes it possible to stir and mix reliably and sufficiently, and also to mix uniformly. Moreover, the flat opening 3a of the nozzle body 2
The nozzle main body 2 itself can be constructed simply by partially compressing the pipe material from the outside, making it easy to manufacture.

In particular, by forming the tip nozzle 4 in the shape of a pipe that gradually narrows at the tip, the spraying pressure on the object mixed with the agglomerate that has passed through the intermediate nozzle 3 is increased, and the sprayed object is powerfully sprayed. At the same time, it becomes possible to spray in a straight line and over a long distance.

By the way, the joint 1 is connected to a joint main body 5 to which a hose 26 for feeding the object to be sprayed can be connected.
The joint outer shell body 10 is fitted onto the outside of the joint body 5 and has a pipe attachment part 12 to which a hose 32 for feeding agglomerate can be connected. A plurality of communication holes 6 are bored along the joint outer shell 10.
By forming a communication groove 11 in the inner circumferential wall surface of the joint 1 that surrounds the plurality of communication holes 6 of the joint body 5 and communicates the communication holes 6 with the pipe attachment part 12, aggregates can be prevented in the joint 1. It becomes possible to feed the agent to the nozzle body 2 while sufficiently mixing the agent with the object to be sprayed. In addition, since the agglomerate is fed to the joint 1 by the air pressure of the compressor 30, the agglomerate is reliably and uniformly mixed with the object to be sprayed at the spray nozzle A portion, and the nozzle The feeding force to the main body 2 becomes stronger, the spraying ability of the seed sprayer S can be improved, and the work efficiency can be greatly improved. Moreover, the configuration is simple, the durability is excellent, and the maintenance is easy.

Furthermore, a plurality of communication holes 6 are bored in the peripheral wall of the joint body 5 along the circumferential direction, and the plurality of communication holes 6 of the joint body 5 are surrounded by the inner peripheral wall surface of the joint outer shell 10. By recessing and forming the communication groove 11 that communicates the communication hole 6 and the pipe attachment part 12, the object to be sprayed sent to the spray nozzle A can be moved inside the joint body 5 toward the tip of the nozzle body 2. When moving, the agglomerate fed to the spray nozzle A can be mixed smoothly and uniformly around the object to be sprayed from the plurality of communication holes 6 through the communication groove 11.
