BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a oscillating nozzle device for a sprayer for spraying a liquid such as a chemical solution, a liquid fertilizer, and water on agricultural products and the like.

[0002]

2. Description of the Related Art Conventionally, in various orchards and the like, a traveling sprayer or a walking sprayer on which an operator rides to spray a chemical solution or the like has been used.

[0003] For example, the traveling sprayer carries a vehicle such as a chemical liquid, a liquid fertilizer, or water in a tank mounted on the vehicle body through a spray nozzle provided at a rear portion of the vehicle body or the like while the operator is traveling. It is configured to be able to spray toward both left and right sides in the traveling direction of the vehicle.

[0004] The spray nozzle is generally mounted on a support provided at the rear of the vehicle body or the like, and may be configured to swing by a mechanical swinging device of the spray nozzle specially provided to enhance the spraying effect. Had been proposed.

[0005]

In the above-mentioned conventional spray nozzle device, the spray nozzle is fixed to the supporting column regardless of whether the traveling road surface is uneven or inclined, so that the spray direction is Of the liquid, such as a chemical solution, a liquid fertilizer, and water.

In addition, a mechanical swinging device for the spray nozzle must be provided, which makes the device complicated and expensive.

The present invention has been made in view of the above circumstances, and does not require the provision of various complicated mechanical swinging devices, and has a simple configuration and a spray nozzle and its spraying according to the unevenness, inclination, etc. of the running road surface. It is an object of the present invention to provide a swing nozzle device for a sprayer in which a direction is automatically changed and a chemical solution can be sprayed efficiently.

[0008]

In order to solve the above-mentioned problems, the present invention provides a method in which a suitable number of nozzle tubes having spray nozzles attached to both ends thereof can swing about a center thereof on a support provided on a vehicle body. And a weight is provided below a substantially central portion of each of the nozzle tubes.

[0009]

When the sprayer having the oscillating nozzle device of the present invention is used, even when the vehicle body 1 is tilted on an inclined ground or the like, the spraying of the chemical liquid can be performed efficiently without unevenness of spraying.

That is, in the oscillating nozzle device of the present invention, a substantially central portion of a nozzle tube 8 having spray nozzles 7 attached to both ends thereof is attached to a column 6 provided on the vehicle body 1 so as to be oscillatable. A weight 10 is attached below a substantially central portion of the nozzle tube 8.

Therefore, when the traveling road surface is flat,
As shown in FIG. 4, the left and right spray nozzles 7 are nozzle pipes 8.
Due to the function of the weight 10 provided below the substantially central portion, the medicine is always kept almost horizontal, and the spraying of the medicinal solution to the fruit trees and the like on both sides can be performed efficiently.

Next, the traveling road surface is not flat,
In the case of a sloping ground or the like, as shown in FIG. 5, the vehicle body 1 is inclined, but the nozzle tube 8 and the left and right spray nozzles 7 attached to both ends thereof are automatically swung by the action of the weight 10. It is possible to perform an efficient spraying of the chemical solution without being affected by the inclination, etc., and evenly spraying the fruit trees on both sides.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view of a traveling sprayer to which the swing nozzle device of the present invention is attached, FIG. 2 is an enlarged perspective view of the swing nozzle device, and FIG. 3 is a swing nozzle device showing another embodiment. FIG. 4 is a rear view showing a use state of the traveling sprayer on a flat ground, and FIG. 5 is a rear view showing a use state of the traveling sprayer when the vehicle body is tilted.

The traveling sprayer shown in FIG. 1 has a driver's seat 2 provided with an operating handle provided in front of a vehicle body 1, a traveling device 3 composed of a traveling crawler provided on a lower surface, and A tank 4 for storing a liquid such as a chemical solution, a liquid fertilizer, and water is mounted on the vehicle body 1 at a rear position, and is integrally configured.

The liquid in the tank 4 is transferred to the motor 5
Are supplied to nozzle pipes 8 which are respectively swingably attached to a support column 6 provided upright at the rear of the vehicle body 1 by a pump (not shown) driven by the pump, and attached to the left and right ends of the nozzle pipe 8. The spray nozzle 7 is configured to spray toward both left and right sides in the traveling direction of the vehicle body 1.

The vehicle body 1 may be either a vehicle on which an operator rides or a vehicle on which the operator walks and runs with an operating handle.

The present invention relates to the improvement of the spray nozzle 7 attached to the support 6.

That is, as shown in FIG. 2, a substantially central portion of a nozzle pipe 8 of an appropriate length having spray nozzles 7 attached to both left and right ends is swingably attached to the rear surface of the support 6, Further, weights 10 are respectively attached below substantially the center of the nozzle tube 8.

In the embodiment of FIG. 2, the nozzle tube 8
Are attached to the support 6 via a return joint 9.

Although not shown in detail, the return joint 9 is provided with a liquid passage for a chemical solution, liquid fertilizer, water or the like therein, and a fixed portion 9a on the support column 6 side and a central portion side of the nozzle tube 8 are provided. And the rotating portion 9b connected to the supporting column 6 is smoothly rotated relative to each other, so that the liquid can be supplied to the spray nozzle 7 from the inside of the support 6 (not shown).

According to the present invention having the above structure, the nozzle tube 8 and the spray nozzle 7 are always kept substantially horizontal by the function of the weight 10 attached below the substantially central portion of the nozzle tube 8 regardless of the inclination of the vehicle body 1. Swing to become.

The nozzle tube 8 with respect to the support 6
Is not limited to the above embodiment. For example, as shown in FIG. 3, a pivot support shaft 11 is provided on the support column 6, and the nozzle tube 8 is attached to the support shaft 11. The bracket 8a protruding upward from a substantially central portion may be fitted and simply suspended and supported.

A weight 10 is provided below a substantially central portion of the nozzle pipe 8. Instead of the weight 10, a liquid supply pipe is provided below a substantially central portion of the nozzle pipe 8 via a return joint 14. 13 to the nozzle tube 8
It may be configured such that the chemical liquid hose 12 itself has a role of a weight.

In the sprayer having the oscillating nozzle device of the present invention having the above-described structure, when the traveling road surface is flat, as shown in FIG. Of the vehicle body 1 is held parallel to the ground toward the left and right sides in the traveling direction of the vehicle body 1, and the spraying of the medicinal solution to the fruit trees and the like on both sides can be performed efficiently.

Next, the traveling road surface is not flat,
In the case of sloping ground or the like, as shown in FIG. 5, the vehicle body 1 is inclined, but the nozzle 10 and the spray nozzles 7 attached to both ends thereof are operated by the weight 10 attached to the substantially central portion of the nozzle 8. Automatically rotates to keep it almost level at all times,
It can be swung appropriately by the inclination of the vehicle body 1 or the like, so that the chemical solution can be sprayed efficiently on the fruit trees on both sides without unevenness.

As described above, according to the present invention, a special mechanical swinging device is not required, and the chemical solution can be sprayed efficiently with a simple mechanism without uneven spraying.

[0028]

According to the present invention, the spray nozzle 7 is automatically swung in accordance with the unevenness, inclination, etc. of the running surface with a simple structure, so that the chemical spraying operation can be performed efficiently. An effect that can be provided at low cost is obtained.
