Description

[Detailed Description of the Invention] The present invention relates to a small amount chemical sprayer for controlling pests inside greenhouses.

In other words, it is a hydrating agent that has been made into ultra-fine particles and placed on convection inside a crop cultivation greenhouse so that it can be efficiently sprayed to every corner.
This sprayer can be inserted halfway through the greenhouse's doorway for good spraying, or the spray unit removed from the machine can be installed inside the greenhouse and sprayed well. The purpose of the present invention is to provide a structure that allows for good spraying depending on the working conditions, and prevents chemical damage by preventing the chemical from leaking during movement or when the operation is stopped, so that it can be carried out suitably.

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

A shows the entire machine, and this machine A has stays 8, 8 hanging down on both sides of a planar U-shaped body frame 7 with a front cover 7a connected to the front part. The running wheels 1, 1 are mounted on both sides of the lower part, both handle rods 9, 9 are extended from the rear of the fuselage frame 7, and a stand 10 is hung from the rear of the fuselage frame 7. A chemical tank 5 is installed on one side, and an engine E is installed on the inside of the front side thereof.A compressor 3 and a generator 2 are connected in front of the engine E so that they can be driven by the engine E. A drug supply pump 4 is installed below the lower surface of the drug tank 5 between both traveling wheels 1, 1, and above the compressor 3 and the generator 2 is the front part of the body frame 7. The front cover 7a is also provided with a mounting base 11 that is connected to the front cover 7a.

A transmission belt 12 is also provided that extends from the front part of the generator 2 to the front part of the drug supply pump 4.
The clutch pulley 13, which comes into contact with the belt 12 to perform a clutch operation, is connected to the operating lever 14 on the grip 9a side of the handle bar 9.
The drug supply pump 4 and the upper drug tank 5 are connected to each other through a suction hose 15 and a return hose 16.
A discharge hose 18 is extended from a balance stock 17 installed on the pump 4 side, which is the base side of the return hose 16, and a discharge hose 19 extending from the compressor 3 is connected to the generator 2. The extending cord 20 and the discharge hose 18 extending from the balance stock 17 and having a gauge 21 interposed therein are connected to connectors 22, 23, and 24 on the side panel of the mounting base 11, respectively.

B shows the entire spraying unit, in which the front part of the duct b has an opening 25, a net 26 is stretched over the rear opening, a handle 27 is fixed to the upper part, and both sides of the duct b have a support frame with a front shape. The base 28 is rotatably supported on both upper sides of the base 28 via support shafts 29 that are coaxial in the horizontal direction, and the support frame base 28 is mounted on the mounting base 11 with the duct b being higher than the drug tank 5. The mounting base 11 is connected to the upper surface and has a knob 30 inserted into the lower surface of the support frame 28 as a vertical axis.
It is removably screwed into the nut 31 on the side, and the mounting base 11
The knob 30 can be rotated about the vertical axis of the knob 30, and the mounting base 11 can be removed.

In addition, a motor 33 is mounted at the center of a rectifier plate 32 which also serves as a stay, which is installed inside the rear part of the duct b, and an axial fan 6 driven by the motor 33 is mounted on the mesh 26 side. , adapters 34, 3 are installed in the center of the duct on the side of the opening 25.
A spray nozzle c supported by a body 36 is constructed as shown in FIG.
A nozzle tip 37 communicating with the adapter 34 is inserted therein, a packing 38 is fitted between the body 36 and the nozzle tip 37, and a resonance box 4 is provided in front of a diffusion hole 39 formed at the front of the nozzle tip 37.
0, and a drug passage 41 that communicates within the adapter 35 and communicates with the outer periphery of the nozzle tip 37 is formed so as to communicate with the intermediate outer periphery of the diffusion hole portion 39.

Joint 34 serving as the lower end of the adapters 34, 35
Hoses 19a and 18a extending from the connectors 22 and 24 are connected to the connectors 22 and 24, respectively, and a cord 20a extending from the motor 33 is connected to the connector 23.

In the figure, D indicates a house for cultivating crops, and F indicates a crop.

Therefore, the spray unit B can rotate around the support shaft 29 as shown by arrow A to change the direction of the opening 25 in the vertical direction.
The direction of the opening 25 can be changed to the horizontal direction by rotating the opening 25 about the vertical axis as shown by the arrow B.

During work, the entire aircraft can be moved by operating the handle rods 9, 9. When the compressor 3, generator 2, and pump 4 are operated by starting the engine E, the axial flow fan 6 moves into the net 26.
Air is taken in from the side and forced into the opening 25 side, and the medicine in the medicine tank 5 is sprayed in the form of ultrafine particles from the spray nozzle c.

As shown in Figure 5, if the spray duct B is inserted into the doorway of the house D, a part of the machine A can be exposed outside the house even if the operator does not enter the house. Spraying work can be performed, and in that state, the orientation of the opening 25 of the spray unit B can be moved up or down or horizontally as described above, while the orientation of the machine A cannot be changed. able to perform work.

Furthermore, as shown in Fig. 6, the spray unit B can be removed from the mounting base 11 and installed in a house D away from the main unit A outdoors for spraying work. 28, and the direction of the opening 25 can also be changed in the same manner as described above.

When the machine is stopped and moved, the spray nozzle c in the spray unit B is located at a higher position than the drug tank 5, so the drug will not naturally leak out from the nozzle c, and the machine will be protected from chemical damage. Reception will be prevented.

In this way, the present invention provides an engine, a generator that is transmitted from the engine, a compressor, a drug supply pump, and a device that communicates with the machine, which can be driven by running wheels, at a position higher than the drug supply pump. an axial flow fan connected to the generator and driven by the generator, each equipped with a chemical tank and having both front and rear ends open;
Since the spray unit equipped with the compressor and the spray nozzle communicating with the chemical supply pump is removably connected to the main unit at a position higher than the chemical tank, this sprayer can be installed in the greenhouse. With the sprayer partially penetrated from the doorway, the operator can perform spraying work without having to enter the house.
Only the spray unit that has been removed from the machine can be installed inside the greenhouse to perform the spraying work properly, allowing for excellent spraying depending on the state of the greenhouse and work conditions. Since the unit is mounted on this machine, it has a structure that prevents chemical leakage and prevents chemical damage, and has the advantage of being suitable for implementation.
