Description

[Detailed description of the invention] The present invention is a greenhouse spraying device, more specifically, it is installed in a greenhouse and fills the greenhouse with atomized chemical droplets to extinguish agricultural products grown in the greenhouse. Regarding a spray device.

Conventionally, this type of spray device includes a sprayer in which a blower fan is installed inside a casing having an air intake port and an air outlet, and a spray nozzle is provided inside the air outlet of the casing, and the sprayer is supported. The spray nozzle is connected to a chemical liquid tank and an air pump, respectively, so that the chemical liquid is atomized by compressed air sent from the air pump, and the chemical liquid sprayed from the nozzle is caused by air blowing from the fan. One known method is to diffuse the air and create an airflow inside the greenhouse.

However, according to this conventional spraying device, especially in the case of a large greenhouse where the length of the greenhouse is significantly longer than the width of the greenhouse, for example, the width of the greenhouse is about 10 m and the length of the greenhouse is 70 m.
In the case of a large, elongated greenhouse measuring ~100 m, a spraying device is installed at one end of the greenhouse in the longitudinal direction, and the chemical solution sprayed from the spray nozzle is spread toward the other end of the greenhouse. , the airflow generated by the air blowing from the fan spreads across the entire width of the greenhouse, and prevents air at the other longitudinal end of the greenhouse from flowing toward the spray device;
The internal pressure at the other end in the length direction of the greenhouse gradually increases, and as a result, the chemical droplets cannot reach the other end of the greenhouse, and the chemical droplets are not applied to all of the crops grown in the greenhouse. It was not possible to make it adhere.

Furthermore, conventional spraying devices have a structure in which the blowing direction cannot be reversed unless the spraying device is lifted together with the base and reversed.
For example, when spraying inside a greenhouse transformed into an L-shape or a T-shape, it is necessary to go into the greenhouse to the installation position of the spraying device and turn the sprayer over with its base. However, when spraying is carried out inside a greenhouse, the inside of the greenhouse is filled with droplets of chemical solution, so entering the greenhouse poses a health hazard.

Therefore, when used in the modified greenhouse, the sprayer must wait until the droplets have finished falling before entering the greenhouse and then turn the sprayer upside down, resulting in very poor work efficiency.

The present invention was devised in view of the above points, and its purpose is to provide a rotating body for rotating a sprayer supported on a base with respect to the base, and a rotating means for rotating the rotating body by operation from outside the greenhouse. By installing the sprayer near the center of an extra-large elongated greenhouse or extra-large greenhouse, or at the intersection of a deformed greenhouse, you can control the blowing direction within the greenhouse by operating it from outside without having to enter the greenhouse. This allows it to be changed in a predetermined horizontal direction.

Therefore, the configuration of the present invention includes a sprayer B in which a blower fan 3 is installed inside a casing 2 having an air suction port 21 and an air blowout port 22, and a spray nozzle 5 is provided on the side of the air blowout port 22; This is a greenhouse spraying device equipped with a chemical tank 6 to which a nozzle 5 is connected via a liquid suction pipe 53, and a rotating body 9 can be rotated around a vertical axis on a base 1 disposed in the greenhouse. The above-mentioned sprayer B is mounted on this rotating body 9
and a drive motor 1 that supports the chemical tank 6 and rotates the rotating body 9 on the base 1.
2, the drive shaft 12a of the motor 12 is connected to the rotating body 9, and a controller 14 for controlling the motor 12 is connected to the motor 12 so as to be controllable from outside the greenhouse. The blowing direction can be reversed by rotating the rotary body in this operation.

The fan motor 4 and the air pump 7
The blower fan 3 blows out air from the center in the length direction of the greenhouse A through the air outlet 22, and blows air into the greenhouse A from the center in the length direction to one end of the greenhouse A. Along with creating airflow,
This blown airflow collides with the side wall surface of one longitudinal end of the greenhouse to generate a return airflow, and the return airflow, the blown airflow and the air suction port 21 of the casing 2
A circulating airflow is generated in the greenhouse A by the suction airflow generated on the side, and the compressed air sent under pressure from the air pump 7 is jetted into the greenhouse A from the air jetting port 52a of the jetting nozzle 5. By the ejection force of this compressed air, the chemical liquid in the tank 6 is sucked into the chemical liquid passage 51c of the spray nozzle 5, and is sprayed into the greenhouse A from the chemical liquid outlet 51d. The particles of the chemical solution are finely crushed and dispersed by the air blown from the fan 3, and are dispersed in the blowing airflow, return airflow, and
It is carried by the suction airflow to the entire area from the center of the greenhouse to one end. At this time, drive motor 1
2 is stopped.

Next, the forward rotation switch 14a of the controller 14 disposed outside the greenhouse A is pressed to rotate the drive motor 12 in the forward direction, and the forward rotation of the drive motor 12 causes the rotating body 9 to rotate in the forward direction. The blowing direction of the sprayer B supported on the rotating body 9 is reversed, and

When the work is finished, the reverse rotation switch 14b is pressed to reverse the rotation of the drive motor 12 and the rotating body 9, thereby reversing the air outlet 22 of the sprayer B to its original direction.

Furthermore, when spraying in a deformed greenhouse that has been deformed into an L-shape or a T-shape, for example, press the forward rotation switch 14a, rotate the drive motor 12, and eventually the rotating body 9, by a predetermined angle while watching the indicator meter 14c. The air outlet 22 is inverted by a predetermined angle.

After setting the amount in advance and turning on the power switch 14d for a certain period of time, the programmable timer 14e operates to rotate the drive motor 12 for a certain period of time. By doing so, it is possible to work unattended, and the blowing direction can be changed one after another at regular intervals.

Further, in addition to being supported by the base 1 via the thrust bearing 11, the rotating body 9 may be supported via a metal bearing or the like, or may be supported without using a bearing. In short, any structure is sufficient as long as it can be easily rotated by the rotating means.
