Next, the action of this spray wheel will be explained.

First, lawn seeds as spraying materials are put into the pressurized tank 3, as well as fertilizer and water, and the agitation engine 8 is operated to perform PR and agitation to make a uniform fluid.

If the spray position is low head or the fluid is low concentration,
The pressurized tank 3 is closed by the lid 6, and the air compressor 4 is operated to increase the pressure in the upper pressurized space 3a and pressurize the fluid. Thereafter, as shown by the two-dot chain line in FIG. 2, the on-off valve 16 of the low-pressure spray pipe 15 connected to the pressurized tank 3 is set to the open position, and the fluid is sprayed onto the slope etc. using the hose 17. Immediately before the end of the spraying operation, the on-off valve 16 is set to the closed position as shown by the solid line, and the on-off valve 19 of the impulse pipe 18 is set to the open position as shown by the two-dot chain line in the figure. Compressed air in the pressure space 3a is sent, and this compressed air removes the fluid that tends to remain in the hose 17 and cleans the hose 17.
Can be sprayed without waste.

If the spray position is at medium head or the fluid is at medium concentration,
Open the lid 6 to open the pressurized tank 3, and at the same time set the on-off valve 14 of the connecting pipe 13 to the open position and turn on the slurry pump 12.
The fluid in the pressurized tank 3 is introduced to the slurry pump 12, and the slurry pump 12 pressurizes the fluid, and the on-off valve 22 of the high-pressure spray pipe 21 is set to the open position as shown by the two-dot chain line in FIG. 2 to carry out the spraying operation.

Immediately before the end of the spraying work, the pressurized tank 3 is closed with the lid 6, the air compressor 4 is operated to increase the pressure in the upper pressurized space 3a, and the on-off valve 25 of the pressure pipe 24 is set to the open position to perform high-pressure spraying. Compressed air in the upper pressurized space 3a is sent into the pipe 21, and the fluid that tends to remain in the hose 23 is removed by spraying.

If the spraying position is at a high head or the fluid is highly concentrated, the pressurized tank 3 is closed by the lid 6 and the air compressor 4 is operated to increase the pressure in the upper pressurized space 3a to pressurize the fluid. At the same time, the fluid is pumped to the slurry pump 12, and the slurry pump 12 further pressurizes the fluid.

Then, the work of spraying the fluid onto the slope etc. is performed. In this case as well, just before the end of the spraying operation, the compressed air in the upper pressurized space 3a is sent into the high-pressure spray pipe 21 to remove the fluid that tends to remain in the hose 23.

The pressurized tank 3 was connected to the low-pressure spray pipe 15 via the on-off valve 16, and the slurry pump 12 was connected to the high-pressure spray pipe 21 via the on-off valve 22. Selectively perform spraying work using the pressurized tank 3, spraying work using the slurry pump 12, and spraying work using the pressurized tank 3 and slurry pump 12 at the same time depending on the lift height or the concentration of the fluid. At the same time, work efficiency can be improved.

Further, the low-pressure spray pipe 15 and the high-pressure spray pipe 21 are provided with pressure guide pipes 1B and 2 that communicate with the upper pressurized space 3a of the pressurized tank 3, respectively.
4 was connected, and the compressed air was sent to both secondary pipes 15.21 just before the end of the spraying operation, so the hose 17.2
The spraying work can be carried out without waste without leaving any fluid in the hose 17, 23, and the hose 17, 23 can be cleaned easily.

Further, since the stirring blade 11 has a pair of left and right through holes 11a, it is possible to reduce the resistance caused by the fluid during the stirring operation, thereby reducing the load on the stirring engine 8, and to quickly and uniformly stir the fluid.

Note that, in addition to plant seeds such as lawn seeds, cement, fertilizer, earth and sand, pulp, etc. may be used as the spraying material.

Further, as the slurry pump 12, a high pressure slurry pump or a two-stage high pressure slurry pump is used.

Further, in the embodiment described above, the pressure guiding pipes 18 and 24 are connected to the upper pressurizing space 3a of the pressurizing tank 3, but they may be directly connected to the air compressor 4.
