Description

[Detailed description of the invention] This invention relates to a power sprayer that sprays a chemical solution into a mist.

For example, when spraying a chemical solution on mulberry trees grown in the ridges, a powered sprayer with a self-propelled function is moved along the ridges,
If the spraying direction of this power sprayer is set perpendicular to the direction of movement of the aircraft, the chemical solution will be sprayed on the outer surface of the leaves that are exposed to the outside, and on the underside of the leaves and deep inside the leaves hidden in the surface layer. The chemicals are not sprayed sufficiently on the leaves.

In addition, if the spray direction is directed 45 degrees outward toward the front of the aircraft, it is possible to spray the mulberry ridge side surface layer, the back side, and the back of the mulberry, but these spray areas are different from the spray direction. The chemical solution is not sufficiently sprayed on the facing side and the rear side in the direction of movement of the aircraft, and for this reason, the entire area cannot be sprayed unless the aircraft is moved back and forth to the mulberry trees in the same ridge to spray the chemical solution. Therefore, the object of this invention is to provide a power sprayer that can spray a chemical solution well to the underside and inner leaves of leaves in one run.

According to the power sprayer of this invention, in order to achieve the above-mentioned purpose, the spray direction of the plurality of spray ports is alternately oriented toward the front side diagonally outside and the rear side diagonally outside with respect to the traveling direction. Therefore, it is possible to spray the chemical solution on cultivated plants from the front and back of the direction of movement of the power sprayer, and in one movement of the machine, it sprays on the front leaves, the underside of the leaves, and the front and back of the leaves hidden behind the leaves. On the other hand, it has the effect of uniformly dispersing the chemical solution.

Moreover, the structure is extremely simple, as it only requires alternating the directions of spraying from a plurality of spray ports.

An embodiment of this invention having such effects will be described in detail based on the following drawings.

The drawing shows a power sprayer with self-propelled function, frame 1
A chemical liquid tank 2 mounted on the front part is connected to a pump 4 at the rear by a connecting pipe 3, and this pump 4 is driven by a motor 5 to discharge chemical liquid, and the discharged chemical liquid is transferred to a connecting pipe 6.
It is connected to chemical liquid supply pipes 7, 7 erected at the front of the machine.

The above-mentioned chemical solution supply pipes 7, 7 can be rotated laterally to the left and right positions of the frame member 8' connected to the lower end of the support column 8 fixed to the front part of the frame 1, so that the upright state thereof can be tilted. It is set up to be
The bending links 9, 9 provided between the intermediate portions of the chemical solution supply pipes 7, 7 and the upper end of the above-mentioned pillar 8
The tilted state is set by fixing 10.10, that is, by fixing the refraction angles of the refraction links 9,9.

Four spray rivers 1a, llb are provided in the above-mentioned chemical solution supply pipes 7, 7, respectively, at appropriate intervals in the vertical direction.

The above-mentioned spray ports 11a and 1lb are arranged alternately, and the spray direction of the spray port 11a is set to the forward 45° outward direction in the direction of movement of the aircraft, and the spray direction of the spray port 11b is set to the rearward outward 45° direction. The spray direction is set to .

The drive wheels 12, 12 at the front of the machine body are individually driven and controlled by independent motors on the left and right sides, and the rear steering wheel 13 performs steering by swinging.

The sensors 14.14 protrude outward on the left and right sides, and when these sensors 14.14 touch the side of the ridge, the motors of the drive wheels 12, 12 on the opposite side to the side they touched are stopped, and the aircraft moves along the ridge. Perform directional control as much as possible.

In the figure, 15 is a battery, and 16 is a motor control device.

As shown in FIG. 3, when the power sprayer A runs unmanned in the direction of the arrow B, the chemical solution sprayed from the spray nozzle 11a becomes the diagonally outward front side C in the direction of travel, and the spray nozzle 11b
The chemical liquid sprayed from the rear side D is diagonally outward in the direction of movement, and the chemical liquid is sprayed from the front and back of the cultivated plants in the ridge 17, so that the chemical liquid can be completely sprayed to the back side of the leaf and the front and back of the back leaf.
