BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paddy field chemical spraying device.

[0002]

2. Description of the Related Art In the case of using a spraying device having a wide spraying nozzle which has been widely used for spraying chemicals in paddy fields, a power spraying device main body equipped with a chemical tank, a prime mover and pumps is placed on a farm road, and then The hose is pulled out for a long time, and the chemicals are sprayed onto the paddy field through a spray nozzle attached to the tip of the hose. In this case, as a worker, in addition to one operator of the power spraying device on the farm road and one nozzle holder in the paddy field, two or three people with a hose in the middle, a considerably large number of workers are required. did. Further, the hose holder always requires a great amount of labor in order to move on a ridge or a field where the feet are not good, and since the drug hose is dragged in the field, there is a problem that the crop is damaged.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. 1 is an overhead view showing a usage state of an embodiment of the present invention, FIG. 2 is a rear view of the spraying work vehicle of the embodiment of FIG. 1, and FIG. 3 is a side view of the spraying work vehicle of FIG. is there. In this embodiment, a vehicle 3 equipped with a power spraying device such as a small truck for agriculture running on a farm road 2 which is in contact with one end of a paddy field 1 to which a chemical is sprayed.
And a high-clearance work vehicle 4 diverting the body of a passenger rice transplanter running in the paddy field 1, and the vehicle 3 equipped with the power spraying device has a drug tank 5 for storing a liquid agent and a drug agent. A high-pressure plunger pump 6 for inhaling and pressurizing the tank 5 to deliver a pressurized medicine, and a prime mover 7 such as an engine and a motor for driving the pump 6,
A normal automatic wind-up type power spray device 22 including an automatic wind-up type drum 9 around which a high-pressure hose 8 having a total length of about 100 m described later is wound is mounted. A rear end of the hose 8 wound around the drum 9 is connected to a delivery port of the pump 6 by a connecting pipe 10. The tip of the hose 8 is connected to a one-touch type hose connection port 11 (FIG. 3) provided at the rear end of the work vehicle 4. The drum 9 is driven from the prime mover 7 through a suitable rotary transmission (not shown),
As the spraying work vehicle 4 moves forward and backward in the paddy field 1, the hose 8 can be operated so as to be pulled out and wound up from the drum 9.

As shown in FIGS. 2 and 3, the spraying work vehicle 4 includes a pillar 12 that stands upright in front of the driver's seat and a chemical cock 13 that projects upward in the vicinity of the base of the pillar 12.
And the lower end of the medicine cock 13 is connected to the hose connection port 11 through a hose 14. A twisting metal fitting 15 is attached to the upper end of the medicine cock 13, and the twisting metal fitting 15 connects a rod-shaped combination spray nozzle 17 through a flexible joint pipe 16. The nozzle 17 is provided with a plurality of spray nozzles 18 separated from each other in the longitudinal direction. With such a configuration, the hose connection port 1 of the work vehicle 4 is passed through the hose 8 from the vehicle 3 equipped with the spraying device.
The medicine sent under pressure to 1 is a hose 14, a medicine cock 13,
It is supplied to the combination nozzle 17 through the return fitting 15 and the flexible joint pipe 16, and is sprayed from the respective spray nozzles 18 to the paddy field.

Since the combination nozzle 17 is provided with the flexible joint pipe 16, the combination nozzle 17 can be pivoted in the vertical direction of arrow A in FIG. Furthermore, the column 12 rotatably supports a ring-shaped member 19 on its upper end, and the ring-shaped member 19 is connected to the combination nozzle 17 via a turnbuckle 20. The twisting fitting 15 and the ring-shaped member 19 are similar to the combination nozzle 17 shown in FIG.
It is possible to rotate the spraying work vehicle 4 on the arrow B in the leftward or rightward direction by about 180 degrees.

The spraying work vehicle 4, as shown in FIG.
Drive on the track 22 between the crops 21 in a direction approximately perpendicular to. When the spraying work vehicle 4 moves forward, the combination nozzle 17 is rotated and fixed in advance, for example, to the left side of the work vehicle 4 to spray the chemicals to the crops on the left side of the spraying work vehicle 4. When the work vehicle 4 moves backward, the combination nozzle 17 is rotated and fixed to the right side of the spraying work vehicle 4 to spray the chemicals to the crops on the right side of the spraying work vehicle 4. During the spraying work, the hose 8 is pulled out or wound up from the drum 9 according to the movement of the work vehicle 4,
If you adjust the positions of the vehicle 3 and the spraying vehicle 4 in advance,
There is no contact with the crop 21, and there is no need for an operator to hold the hose 8 in the middle, and the crop 21 is not damaged by the hose 8 or the like. In this way, when the spraying work on both sides is completed by one reciprocation, the power sprayer-equipped vehicle 3 and the spraying work vehicle 4 are moved to the left or right on the farm road 2 by about twice the one-sided spraying range. The above-described reciprocal spraying work can be repeated to spray the chemicals on the entire paddy field 1. Actually, 20 to 3 in one reciprocating spraying width of 10 to 15 meters on one side
Since the drug can be easily sprayed over about 0 meters, one standard section of 100 m × 30 m can be sprayed in one round trip. Further, it is also possible to make the drug spraying range larger than that. The device of the present invention can be used not only in paddy fields but also in upland fields, and existing agricultural vehicles can be used as the vehicle 3 equipped with a power spray device and the spraying work vehicle 4, respectively. It is more preferable to use the spraying work vehicle 4 which can be operated with the driver's seat 21 in the reverse direction when moving backward.

[0009]

As described above, according to the present invention, it is possible to perform the spraying work efficiently and economically without needing an extra worker such as holding a hose, and to damage the crop during the work. There is no effect, and existing agricultural vehicles can be used, and there is an effect that it can be used not only in paddy fields but also in field areas.
