Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle swing mechanism of a self-propelled pest control device mounted on a traveling vehicle for controlling fruit trees. 2. Description of the Related Art Conventionally, when a pest control operation for a fruit tree or the like is performed while traveling, a self-propelled control device such as a speed sprayer, a boom sprayer towed by a tractor, or a self-propelled device mounted on a traveling vehicle. It is known to carry out with a type pest control machine. These self-propelled pest control machines are composed of an engine, a chemical tank, a pump, a nozzle, a blower, and the like. The chemical in the tank is sucked and pressurized by a pump, sprayed from a nozzle, or further blown up by a blower to produce fruit trees. Was configured to be sprayed from below. [0003] However, in the above-mentioned prior art, the medicine sprayed from the nozzle is blown up by the wind power of a blower and adhered to the fruit tree, so that the spray direction of the medicine is constant. As a result, the agent adheres only to the one-sided back surface of the fruit tree leaves, resulting in a portion that becomes uneven in application. In addition, since it was blown up by the wind power of the blower, it was apt to be unnecessarily sprayed. Therefore, an object of the present invention is to provide a self-propelled pest control device that can enhance the performance of adhering a drug without using a blower, and can prevent the drug from scattering more than necessary and spray it to fruit trees without fail. And [0004] The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

When performing pest control work with a self-propelled pest control machine, a motor that is a rotary drive source provided on the body of the self-propelled pest control apparatus is driven, and at the same time, a chemical is ejected from a nozzle. The rotating link is rotated by the driving force, and at the same time, the driven link arranged in parallel is also rotated, and the rotating plate is rotated so as to draw an ellipse. As a result, the rotating plate is arranged in a fan shape on the rotating plate. The plurality of nozzles swing around the locking member so that the swing trajectory of the nozzle tip draws a circle or an ellipse, and the medicine is sprayed in a spiral. Next, an embodiment will be described. 1 is a schematic front view showing an embodiment of a nozzle swinging mechanism of a self-propelled pest control device of the present invention, FIG. 2 is a schematic plan view thereof, FIG. 3 is a schematic perspective view of another embodiment, and FIG. It is a whole side view of a type pest control machine. The self-propelled pest control machine has a spraying machine B mounted on a traveling section A as shown in FIG. The traveling section A employs a crawler traveling apparatus 12 to reduce the vehicle height and the center of gravity so that traveling on an inclined road is advantageous, and the capacity of the medicine tank can be increased. The crawler-type traveling device 12 has an idler wheel 1 at the front end of a track frame 12e.

A step 14a is provided in this horizontal portion, and a seat 15 is provided on the rear center of the front frame 14. Thus, the seat 15 can be seated at a low position in a gap (not shown) generated between the left and right crawler traveling devices 12. However, since the seat 15 is located between the crawler-type traveling devices 12, the seat 15 can be further lowered, and can be moved up and down so that the seating position can be adjusted. An operation column 16 is erected at the center of the front end of the step 14a.
A steering operation lever 16a protrudes from the upper part. Next, the spraying machine B will be described. The spraying machine B includes a medicine tank 18, an engine E, a power sprayer (not shown),
The medicine tank 18 is arranged behind the seat 15 to increase the tank capacity, and the canopy 17 projects forward from the medicine tank 18 above the seat 15 to be shaded and sprayed. Drugs are not applied. At the rear of the medicine tank 18, the engine E and the power sprayer are mounted in the left-right direction, and are covered by a cover 20 according to the extension of the medicine tank 18 at the front. The base is similarly covered by the cover 21 and can be opened independently. Further, the engine E drives the drive wheels 12b via the transmission case to drive the crawler type traveling device 12, and at the same time, drives the power sprayer to suck the medicine from the medicine tank 18 by the power sprayer.
