Abstract

The utility model relates to a smoking machine for the prevention and treatment of plant pests. A medical liquid tank is connected to a pressurizing oil supply pulsed jet engine. The upper end of the medical liquid tank is provided with an air inlet tube which is communicated with the inner cavity of a carburetor. The tail tube of an engine is covered with a tube which is capable of cooling. The length of the tail end of the tube which is capable of cooling is bigger than the length of the tail tube. The interlayer between the cooling tube and the tail tube is provided with a medical liquid atomization spray nozzle which is communicated with the lower part of the medical liquid tank. Therefore, after the engine is started, the medical liquid fuming diffuses with smoke as carrier and is attached on the surface of plant. The utility model has the advantages of good diffusivity, strong adhesion, resistance to rain flushing, high spray efficiency, low prevention and cure cost, simple structure, small volume, light weight and convenient operation.

Description

Smoking machine

The utility model belongs to the special-purpose smog machinery of plant protection, relates to the extermination of disease and insect pest of plant.

The special equipment device that is used for plant pest management at present has duster and sprayer two big classes, because the form and the carrier of its medicine that sprays are pulvis and aqua, its particle is big, adhesive force weak, diffusibility is poor, institute is low so that spray efficient, control cost height, and it is very big to spray the influence that is subjected to amblent air temperature, and its defective of control especially tall and big to tree crown, the fruit tree that is thick with leaves is more outstanding.The particle that the utility model just is based on smog is little, the invention of finishing on the good basis of strong adhesion, diffusibility.

The purpose of this utility model is a kind of fog machine of design, can be that carrier sprays various medicaments to finish the control of plant pest with smog, makes it to have the advantage that volume is little, in light weight, simple in structure, use is easy to operate.

Architectural feature of the present utility model is that jockey has spray tank on a pressurising fuel feeding aeropulse engine; There are an air inlet pipe and engine vaporizer intracavity inter-connection in the upper end of spray tank, has check (non-return) valve on the air inlet pipe; Be covered with cooling tube at the engine tail pipe, cooling tube tail end length is greater than tail pipe; Sandwich device between tail pipe and cooling tube has an atomizer, and shower nozzle is communicated with the spray tank lower end with pipe; Heat-insulating shield arranged in that engine combustion is outdoor; Manual pumps is adopted in the starting of engine inflation, and the inflator pump escape pipe is through check (non-return) valve to a triple valve, and one of two outlet of triple valve communicate with engine oil tank, and another communicates with the engine vaporizer air inlet; The switch contacts of Motronic control maps pulse igniter is connected in the manual pumps.

From the said structure feature as can be seen, the soup fuming principle of the designed fog machine of the utility model is, after normal working of engine, provide pressure by the engine vaporizer inner chamber to spray tank, soup is the mixture of medicament and diesel oil, under the effect of pressure soup through efferent duct to atomizer, the high temperature and high pressure gas of while after engine tail pipe ejection burning, thereby make the interlayer between tail pipe and the cooling tube form negative pressure, the atomizing soup of shower nozzle ejection then flows to the tail pipe mouth so, effect at HTHP mists medical solution by fuming, discharges from cooling pipe orifice.Medicament then is that carrier spreads with smog, is attached to plant surface, reaches the purpose of prevention and elimination of disease and pests.Since smog have diffusion well, big, the spray of spraying swath is apart from the characteristics of far away, strong adhesion, resistance of rainwater washing against, thereby make the designed fog machine of the utility model the use saving of labor, save time, spray the efficient height, the control cost reduces at double, has only 1/5 to 1/8 of common control, control efficiency can reach more than 95%, and spray the influence that is not subjected to the weather environmental condition, can be applicable to various breasts, fat, oils medicament.And the utility model from design have simple in structure, volume is little, the advantage of in light weight, easy to use, easy operating.

Accompanying drawing is the structural representation of the designed fog machine of the utility model, and 1 is cooling tube among the figure, and 2 is the engine tail pipe, 3 is heat-insulating shield, and 4 is engine chamber, and 5 is electronic impulse ignition apparatus, 6 is manual pumps, and 7 is check (non-return) valve, and 8 is triple valve, 9 is the engine petrol tank, and 10 is check (non-return) valve, and 11 is engine throttle, 12 is spark plug, and 13 is engine vaporizer, and 14 is check (non-return) valve, 15 is spray tank, and 16 is the medical liquid atomizing shower nozzle.Narrate with regard to the starting and the running of the designed fog machine of the utility model in conjunction with the accompanying drawings.The starting of pressurising fuel feeding aeropulse engine is that pneumatically is a power, when pressing the inflator pump piston, gas is compressed in the pump, air-flow is divided into two-way through check (non-return) valve to triple valve, one road air-flow is to petrol tank, make the gasoline pressurized, force gasoline in check (non-return) valve enters the engine vaporizer chamber, another road air-flow then enters in the vaporizer chamber to engine vaporizer end valve by the road, behind gasoline atomizing, form mist and enter the combustion chamber, plug ignition work meanwhile, mist is lighted to set off an explosion, forming first HTHP pulse gas discharges from the engine tail pipe, in air mass is gushed out moment combustion chamber, form negative pressure, force mist to enter the combustion chamber once more, lighted blast by ember, reciprocal with this, finish the starting of engine.The running course of work of the designed fog machine of the utility model is, after engine start, become mist spontaneous combustion blast and form the high temperature and high pressure gas work done, the high temperature and high pressure gas that the blast back produces has sub-fraction to pour into the vaporizer inner chamber, wherein a part is back to petrol tank through vaporizer end valve, give the continuous supercharging of petrol tank, another part then pours in spray tank by the vaporizer chamber through check (non-return) valve, makes pressurized in the spray tank, force soup through efferent duct to atomizer.

Pressurising fuel feeding aeropulse engine, electronic impulse ignition apparatus, manual pumps and the various valve and the shower nozzle that adopt in the designed fog machine of the utility model all have sale in the market, the connection of each pipeline should seal in manufacturing, heat-insulating shield can be made with the asbestos interlayer by the metal plate holder, and the power supply of igniter adopts dry cell.In use, can control the size that the throttle fuel delivery is controlled exhaust smoke level.
