Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microspraying device in a garden greenhouse.

For this type of pest control in garden greenhouses, unmanned automatic devices have been developed, in which a sprayer with a timer set for spraying is installed inside the greenhouse, compressed air is supplied from an external compressor, and an electric cord is connected. This was done by spraying chemicals with a particle size of 0.5 to 10μ using the nozzle and fan of the sprayer.

However, it is equipped with a compressed air supply hose and electric cord, and the area inside the gardening house is small.
Because there is a considerable difference between 1,500 and 600 tsubo, sprayers are large, stationary types, and devices are provided that adjust the amount of spraying simply by lengthening or shortening the spraying time.

For this reason, the larger the equipment, the higher the cost, and for farmers who have multiple gardening greenhouses,
Currently, only one unit can be purchased, which means that the pest control work will only be done at one building per day. Pest control for gardening greenhouses is aimed at controlling the crops themselves, such as cucumbers, tomatoes, and peppers, but it can also exterminate pests that occur in relatively shallow areas of the land, so it is best to do all greenhouses on the same day if possible. This is effective.
In addition, the nozzle is clogged due to insufficient air supply due to damage to the compressed air supply hose, etc., and a certain amount of medicine cannot be atomized. In addition, small-dose spraying is carried out in the evening when the outside air cools down and convection of air inside the greenhouse occurs, so there is a lot of water inside the greenhouse as well.
The chemical is sprayed in a uniform pattern and allowed to spread to take advantage of the air convection inside the greenhouse to control the underside of the leaves of the plants. However, this method requires an auxiliary device that blows air from around the house to make the atomized chemical flow uniformly, which has the disadvantage of increasing the cost. Therefore, there was a desire to develop a device that was small, inexpensive, and capable of reliably spraying small amounts.

The present invention solves these drawbacks and can efficiently control pests throughout the house even in a large greenhouse, and also makes the atomization unit lightweight and small, reducing costs and ensuring safe unmanned work. The purpose of the present invention is to provide the following information so that it can be carried out in a suitable manner.

Next, the embodiment shown in the drawings will be described.

A shows the entire atomization unit as one individual, and a plurality of wheels 6 are mounted on a shaft at the bottom of the chemical tank 1, and the wheels 6 are driven by a motor M installed at the rear of the chemical tank 1. An atomizing cylinder 7 having an opening 7a at its tip is supported by support arms 8, 8 so as to be rotatably adjustable, and is installed above the chemical liquid tank 1. A spout nozzle 3 communicating with the chemical liquid tank 1 and facing toward the opening 7a.
An air blowing body 9 is installed at the rear of the atomizing cylinder 7, and a high-speed reciprocating motion is generated by one electromagnet and one piston at the rear of the atomizing cylinder 7. A linear compressor 2 of a known construction is installed so as to communicate with the jet nozzle 3 and the air blowing body 9, and an electric cord 5 for electrical connection to each part extends from the rear.

B is a large gardening house, and on the ground inside the house B, tracks 4 on which the wheels 6 of the atomizing unit A can roll are laid over the entire length in the longitudinal direction. The opening 10 is laid so as to extend outward, and a drop cloth 11 made of vinyl or the like is suspended from the opening 10 to close the opening 10.

Further, C is a motor generator, which is composed of a combination of an engine E, a generator 12, a timer T, a fuel tank 13, etc., and the motor generator C is installed outside the house B. Electrical cord 5 extending further
is connected to the atomizing unit A, and is configured so that power can be supplied to the atomizing unit A for a certain period of time by setting a timer T.

The track 4 may be built on the upper part of the house B, the atomizing unit A may be suspended from the track, or the track may be a cableway type, and the atomizing unit may be suspended from a wire rope to be self-propelled. Alternatively, it may be configured by moving a wire rope, and the power source is not limited to a motor generator. Further, as shown in FIG. 1, the electric cord is stored in a folded state so that it can be extended on the ceiling of the house.

Then, by extending the electric cord 5 and moving the atomizing unit A to one end of the house B,
When electrical connection is made from that position by setting the timer T, the linear compressor 2 is operated to eject the chemical liquid from the ejection nozzle 3, and the air blowing body 9
Due to the increased air flow, the medicine can be sprayed into the house B from the opening 7a as shown by arrow A. In this state, the atomizing unit A is moved along the track 4 while driving the rolling wheels 6 by the motor M. It is possible to spray the entire house B from one end to the other by moving it in the direction shown by the arrow B.

The atomization unit A is connected to the opening 10 at the inner end of the house B.
When the electrical connection is cut off by the timer T, the entire system stops, and the drape 11 hangs down and closes the opening 10 as shown in FIG. Since it is closed, the atomizing unit A can be taken out to the outside of the house B without being exposed to the medicine inside the house B.

In this way, the present invention installs a single atomizing unit consisting of a chemical tank, a linear compressor, a jet nozzle, etc. inside a gardening house, and uses electricity extended from a power source such as a power generator outside the greenhouse. Since the atomizing unit is connected to the cord and the operation of the atomizing unit is configured to be automatically stopped by a timer, the compressed air supply hose can be damaged or bent due to insufficient amount of atomizing air, or if this air shortage occurs. Eliminates problems such as nozzle clogging,
It is possible to reliably atomize a certain amount of medicine during the operating time set by a timer, and it is small and can be provided at low cost.

In addition, since the atomizing unit in the invention of item 1 is configured to be movable within the gardening house using a track or a cableway, even in a large greenhouse, by moving the atomizing unit, it is possible to disperse the water evenly and well throughout the greenhouse. Since the atomization unit is built inside the linear compressor, there is no nozzle clogging, and it can be operated by simply connecting an electric cord. Furthermore, it is lightweight and compact, making it easy to move, allowing for safe unmanned work. It has characteristics that allow it to be implemented in a suitable manner.
