First, soil, fertilizer, water, seeds, etc. are charged into the stirring tank 1 from the charging port, and these are Stir with the stirring blade body 2. Then, the object to be sprayed, which consists of the stirred soil, fertilizer, water, seeds, etc., falls into the blow-up reservoir case through the drop slot. Then, the object to be blown in the blow-up reservoir case is passed through the feeding pipe 4 by the pressure of the air fed into the stirring tank 1 and the pressure feeding force (suction force) of the main pressure feeding mechanism of the pressure feeding device 20. The pressure of the air that reaches the main pressure feeding mechanism of the pressure feeding device 20 and is further fed into the stirring tank 1 and the pressure feeding force (throttle pushing output) of the main pressure feeding mechanism of the pressure feeding device 20 cause the main movement of the pressure feeding device 20.

At S, the object to be sprayed is continuously fed to the blowing nozzle 36 by utilizing the pressure feeding force of the main pressure feeding mechanism of the pressure feeding device 20 and the pressure of the air fed into the stirring tank 1, while the compressor is being compressed. 5 is provided with air to provide an agglomerate tank 7 formed so that the contained water and the powdery paste material can be appropriately stirred, and the agglomerate in the agglomerate tank 7 is pressure-fed. The auxiliary pumping mechanism of the device 20 and the pressure of the air from the compressor 5 are used to continuously feed the spraying nozzle 36, and the spraying nozzle 36 blows these while mixing the agglomerate with the object to be sprayed. Since it is configured so that it can be attached freely, a stirring tank By the pressure of the air sent inside and the pressure feeding force of the main pressure feeding mechanism of the pressure feeding device 20, the blown object can be fed reliably and smoothly to the blowing nozzle 36, and from the compressor 5 into the agglomerate tank 7. By the pressure of the supplied air and the pumping force of the sub pumping mechanism of the pumping device 20,
The agglomerate can be reliably and smoothly fed to the spray nozzle 36, the object to be sprayed and the agglomerate can be reliably and satisfactorily mixed by the spray nozzle 36, and continuously blown to the front of the spray nozzle 36. As a result, the spraying capability of the seed spraying machine S can be improved, which contributes to a significant improvement in work efficiency. Moreover, the seed spraying machine S has a simple structure, is hard to break down, and is easy to handle.

In particular, in addition to the pressure-feeding force of the main pressure-feeding mechanism of the pressure-feeding device 20, the blown object is fed using the air pressure fed into the stirring tank 1, while the pressure-feeding force of the sub-pressure feeding mechanism of the pressure-feeding device 20 is fed. In addition to the compressor 5 that is fed into the aggregate tank 7
Since the aggregate is delivered using the pressure of the air from
The object to be sprayed or the agglomerate can be strongly fed, and the object to be sprayed or the agglomerate is aggregated even if the output of the pumping device 20 itself (and the output of the prime mover for driving the pumping device 20) is not so large. The agent can be reliably delivered. Moreover,
Even objects to be sprayed or agglomerates having relatively poor fluidity can be reliably delivered by air. Furthermore, the main elastic cylinder 27 and the sub elastic cylinder 28 of the main pressure feeding mechanism and the sub pressure feeding mechanism are
The roller 24 of the main pressing body 23 and the roller 26 of the sub pressing body 25
After being deformed by pressing with, the pressure of these air in addition to the elastic restoring force of the main elastic cylinder 27 and the sub elastic cylinder 28 itself promotes the recovery of the main elastic cylinder 27 and the sub elastic cylinder 28. Therefore, the main elastic cylinder 27 and the sub elastic cylinder 28 can be restored quickly and surely, and the efficiency of the object to be sprayed or the agglomerate in the pressure supply device 20 is reduced even when used for a long time. The seed spraying machine S of this type can be dispensed with, and it is also useful for preventing residual deformation strain of the main elastic cylinder 27 and the sub elastic cylinder 28, and has excellent durability. It is the most suitable feeding means for

Further, the pressure feeding device 20 is provided with a main pressure feeding mechanism and a sub pressure feeding mechanism, and the blown object is continuously fed to the blowing nozzle 36 by utilizing the pressure feeding force of the main pressure feeding mechanism of the pressure feeding device 20. Since the agent is configured to be continuously fed to the spray nozzle 36 by utilizing the pressure-feeding force of the auxiliary pressure-feeding mechanism of the pressure-feeding device 20, it is possible to separately and reliably and strongly feed the object to be sprayed and the aggregate. As a result, it becomes possible to efficiently deliver the sprayed objects and the granules at a pressure suitable for each, and moreover, it becomes possible to use only one power for delivering the sprayed objects and the granules. ,
The number of components of the seed spraying machine S can be reduced, and the seed spraying machine S as a whole can be easily reduced in size, weight and size.

Furthermore, the air from the compressor 5 can sufficiently agitate the water and the powdery paste material in the agglomerate tank 7, and the agitated agglomerate can be sent to the spray nozzle 36 and the spray nozzle 36. It becomes possible to spray these while thoroughly mixing the agglomerate with the object to be sprayed.
