Description

[Detailed Description of the Invention] The present invention relates to a pest control device for a gardening greenhouse for cultivating vegetables and fruit trees.

Gardening greenhouses are almost completely sealed off from the outside air to keep them warm, and it is difficult for pest control workers themselves to spray chemicals onto planted crops using a spout as in the past. The mist of the chemical solution had to be inhaled through the mouth and nose, posing a hygiene problem.

In order to solve this problem, unmanned pest control devices such as a remote control pest control machine and a pest control device with a nozzle fixed to the ceiling of the house have been disclosed, but neither of these devices became popular due to cost and reliability.

In-house pest control device of this invention This is an unmanned in-house pest control device devised to eliminate these problems.This machine is installed at the entrance of the greenhouse and uses a blower to send ultra-fine mist into the greenhouse. ,
Since it is an extremely fine particle, it is intended to be applied to every corner while floating in the air inside the greenhouse.

What determines the performance of this device is whether or not the mist particles can be made into ultrafine particles of about 10 microns, and whether or not the mist can reach every corner of the greenhouse.

The purpose of the present invention is as described above, and the structure of the present invention will be explained based on the structure of the embodiment shown in the attached drawings.

Figure 1 is a side view of the pest control device inside the gardening house, Figure 2
The figure is a front view.

An injection nozzle 14 is provided in a projecting manner within the wind barrel 1 of the blower 2. The blower 2 is directly connected to the motor 3 or driven by a belt. The blower 2 is pivotally supported at a pivot point 6b of the support body 6, is configured to move up and down automatically along the elongated hole 6a, and is fixed with a wing nut.

Inside the bonnet 7 are a prime mover 12 such as an engine or motor, and a compressor 1 for high-pressure air.
3 are juxtaposed. Further, a motor 3 directly connected to the blower 2 is provided.

The prime mover 12, compressor 13, blower support 6, etc. are mounted on a chemical tank 10 and a high pressure air tank 11 of the compressor.

The chemical solution tank 10 and the high-pressure air tank 11 are also used as a chassis, so they are elongated tanks, and rear wheels 15, 15 and a front wheel 16 are provided below them. A handle is provided upright from the bottom of the bonnet 7 toward the rear.

The injection nozzle 14 is provided in a protruding manner within the wind barrel 1 of the blower 2, and the air pipe 4 and the chemical liquid pipe 5 send high-pressure air and chemical liquid toward the injection nozzle 14.

3 is a side sectional view of the injection nozzle 14, FIG. 4 is a front view of FIG. 3, and FIG. 5 is a drawing showing another embodiment of the injection nozzle.

The tips of the air pipe 4 and the chemical liquid pipe 5 are inserted into the nozzle outer cylinder 14a. The high-pressure air is branched into two flows from here, one of which passes through the hole in the nozzle inner cylinder 14b and is then sent to the nozzle opening 14 from the air discharge hole 14h provided at the center of the nozzle body 14g.
It is forcefully blown out from the nozzle small hole along the outside of the shaft portion 14i of the diffuser 14d in f. The chemical liquid reaches the outer periphery of the nozzle body 14g from between the outer periphery of the nozzle inner cylinder 14b and the inner periphery of the nozzle outer cylinder 14a, and from the outer periphery to the air discharge hole 1 at the center of the nozzle body 14g.
The chemical liquid reaches the chemical liquid port 14e, which is perpendicular to the hole 4h, is sucked out by negative pressure, and is blown out vigorously together with the high-pressure air flow to form a jet stream. It is also possible to scatter the chemical liquid with the jet stream emitted from this nozzle, but with this structure alone, the average diameter of the chemical liquid mist is about 300 microns, and it is difficult to stay in the greenhouse for a long time as a floating flow. It's too big and falls down easily.

Since this is insufficient as it is, it is necessary to make the mist flow even finer, about 10 microns. For this purpose, a high-pressure air port 14c is provided in the vicinity of the outlet of the injection nozzle to further generate turbulence in the injection flow and to make the diameter of the mist extremely fine.

The high-pressure air in the high-pressure air port 14c is branched from the high-pressure air pipe 4, and flows from the outside of the injection nozzle.
The air is blown toward the center from three directions at a 120° angle. By blowing from three directions toward the center of the eyes, turbulence occurs especially near the center where they intersect. With these configurations, the mist that is forcefully blown out from the small nozzle hole and becomes fine particles when it hits the diffuser 14d becomes further ultrafine particles of about 10 microns.

As described above, in the present invention, the tips of the high-pressure air pipe 4 and the chemical liquid pipe 5 are inserted into the nozzle outer cylinder 14a, and the nozzle port 14f is fixedly installed at the injection side tip of the nozzle outer cylinder 14a. Fit the nozzle body 14g into the central opening of the nozzle body 14g.
An air discharge hole 14h communicating with the high-pressure air pipe 4 is opened at the center position of the nozzle body 14g, and a chemical liquid port 14e communicating with the chemical liquid pipe 5 is opened toward the air discharge hole 14h from the outer periphery of the nozzle body 14g. Loosely fit the shaft portion 14i of the diffuser 14d into the hole 14h,
The gap formed by the shaft portion 14i and the air discharge hole 14h is configured as a high-pressure air discharge port, and the high-pressure air port 14c disposed on the outer periphery of the injection side of the nozzle port 14f is diverted from the high-pressure air pipe 4, and is opened from three directions. The shaft portion 14i protrudes from the air discharge hole 14h at an angle of approximately 120°.
Since the spray is arranged so as to be injected toward the vicinity of the diffuser 14d fixedly installed at the tip of the spray bottle, the following effects can be achieved.

First, we were able to turn the mist of particles of about 300 microns, which is produced by conventional sprayers, into an ultra-fine mist of about 10 microns, which allows it to be suspended in the greenhouse for a long time on the wind of a blower. By changing the angle of the blower and the wind barrel, it is possible to blow into every corner of the house, from top to bottom, left and right, without creating any blind spots.

Second, by blowing the wind and distributing it to every corner, workers do not need to enter the house, and the work can be completed unattended and at night, resulting in a sanitary environment. That's why.

Thirdly, by blowing high-pressure air centrally from three directions, high-pressure turbulence can be generated with a simple configuration, making it possible to create ultrafine particles without using expensive nozzles. be.
