Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chemical solution spraying device for spraying a chemical solution onto fruit trees and the like on uneven ground such as sloped land.
Generally, in order to apply a chemical solution to the back side of leaves of fruit trees, etc., it is necessary to mix the atomized chemical solution into the air and blow it out with the air. It can be dispersed up to However, conventionally, when citrus fruits are usually cultivated on sloped land such as terraced fields, a portable liquid pump with an engine is installed on the ground to pump the chemical solution from the chemical tank placed on the ground.
It was atomized and sprayed from a nozzle at the end of a long chemical hose. The chemical hose that pumps the chemical liquid has a small diameter and is easy to handle.The worker grasps the nozzle at the end of the chemical hose and moves it over an area according to the length of the chemical hose, spraying it on fruit trees within that range. Ta.
In this case, since the chemical solution is directly atomized and sprayed by a nozzle, large particles tend to fall, making it impossible to sufficiently spray even the shaded areas such as the backside of leaves. For this reason, if a chemical solution is atomized and mixed into the air being blown by an air blower and then sprayed, the chemical solution becomes atomized and floats in the air, and is even sent to the shaded areas such as the underside of leaves. This type of blower had a thick blowing hose and was difficult to handle, making it unsuitable for work on slopes. In addition, some backpack-type chemical sprayers mix chemicals while blowing air, but the amount of chemical liquid is small and the chemical liquid needs to be replenished frequently, and the weight of the chemical liquid is large compared to other parts, making it difficult to operate on slopes. It was not suitable for

The present invention uses a backpack-type blower, installs the heavy chemical liquid tank on the ground to increase capacity, eliminates the need for a difficult-to-handle blower hose, and sprays water using the blower tube attached to the backpack-type blower. In addition, the chemical solution is pumped into the ventilation path by a ground-based liquid pump through a small-diameter chemical hose that is easy to handle, and is atomized to facilitate work even on slopes. The purpose of the present invention is to provide a chemical solution spraying device that can effectively disperse a chemical solution to the back side of leaves by making the chemical solution float in the air.

In the figure, 1 is a chemical tank such as a bucket installed on the ground, 3 is an engine attached to a portable frame 5, 7 is a liquid pump attached to the engine 3,
9 is a hose reel around which one end of the chemical liquid hose 11 is wound. 13 is a suction hose, and the liquid pump 7
The inlet 15 and the chemical solution tank 1 are communicated with each other. 17
are the discharge port 19 of the liquid pump 7 and the hose reel 9
This is a discharge pipe that opens in the shaft portion of the chemical liquid hose 11 and connects it to a communication hole 21 that communicates with the inner end of the chemical liquid hose 11 . 23
shows a backpack-type blower, which is configured as follows. That is, 25 is a backpack frame, a back support 27 for placing it on the back of the worker is attached to the front part, and both ends of a backpack band 29 are connected. 31 is a fan case attached to the backpack frame 25 via vibration isolators 33, 33, and a fan 35 is installed inside.
is rotatably provided. An engine 37 is fixed to the fan case 31 and drives the fan 35 to rotate. 39 is a cylinder cover, 41 is a recoil starter, 43 is a crankcase, and 44 is a fuel tank. 45 is a ventilation passage of the fan 35, which is connected to a ventilation pipe 49 via a flexible pipe 47.
It is connected to the. Reference numeral 51 designates a spray port that opens into the nozzle portion 53 at the tip of the blower pipe 49 and communicates with the chemical solution hose 11 via the chemical solution pipe 55 . 57 is a pot provided in the chemical liquid pipe 55.

In the above embodiment, the worker puts the backpack band 29 on his shoulder, puts the backrest 27 on his back, carries the blower 1 on his back, holds the blow pipe 49 with his right hand, and removes the chemical solution that gets mixed in when the fan 35 is blowing air. It is meant to be dispersed. This chemical liquid is pumped from a chemical liquid tank 1 installed on the ground to a liquid pump 7 driven by an engine 3.
The chemical solution is force-fed through the chemical hose 11 to the spray port 51, atomized during ventilation, and the atomized chemical solution floats during the ventilation and is dispersed along with the ventilation.

Since the present invention has the configuration as described in the claims, on uneven ground such as a slope, a chemical solution is mixed into air blowing, and fine particles are suspended in the air.
It is possible to spray even the shaded areas such as the undersides of leaves, and there is no need for heavy and difficult-to-handle blower hoses.Also, the heavy chemical tank can be placed on the ground and only the lightweight engine and blower can be carried on the back. This makes the spraying work easier.

In the present invention, "installed on the ground" also means that the movable liquid tank and liquid pump are temporarily placed on the ground.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments as well. Further, the symbols shown in the claims do not limit the technical scope of the present invention.
