Abstract

The utility model provides a from inhaling formula negative pressure gasification greenhouse dispensing device, includes medical kit, liquid medicine spray tube, variable cross section waist venturi tube, crossover sub, horn tube, centrifugal blower, air inlet, the bottom of medical kit and the one end of liquid medicine spray tube intercommunication, and the intercommunication is located with the aditus laryngis of variable cross section waist venturi tube to the other end of liquid medicine spray tube, and the one end of variable cross section waist venturi tube is the air inlet, and the other end is held through the osculum of dress changing -over head and horn tube and is connected, and the macrostoma end of horn tube is connected with centrifugal blower's inlet end. The utility model discloses use coordinately variable cross section waist venturi tube and centrifugal blower, the negative pressure that has realized the liquid medicine need not the extra equipment from inhaling, and variable cross section waist venturi tube carries out a negative pressure gasification to the liquid medicine, and the air current that centrifugal fan produced carries out the secondary gasification, has improved the pesticide utilization ratio. This device simple structure, cost of manufacture are hanged down, have realized the electro -mechanical -hydraulic integral spraying, have reduced intensity of labour.

Description

Self-priming Gasification at the negative pressure greenhouse device for administration of drugs
Technical field
The utility model relates to a kind of self-priming Gasification at the negative pressure application equipment being applicable to greenhouse and using.
Background technology
The traditional insecticide-applying way of China sprays after dilute with water agricultural chemicals stoste, and the device for administration of drugs adopted in greenhouse is based on knapsack hand sprayer and motorized knapsack.The green house special ecological environment that airtight, illumination is not enough, hot and humid be for a long time damage by disease and insect generation, breed, spread and provide advantage.In greenhouse, adopt existing device for administration of drugs and application method to there is following defect, (1) agricultural chemicals atomization is bad, easily deposits to soil, cause Pesticide-Polluted Soil when droplet is too large; And droplet too little time easily produce drift, agricultural chemicals waste is serious; (2) in insecticide-applying way generally by agricultural chemicals thin up, extension rate is 100 ~ 3000, significantly increases the humidity of greenhouse closed environment, for germ generation, spread the condition of creating; (3) automaticity is not high, and based on knapsack sprayer, some electromechanical assembly needs manual operation, and labour intensity is large, and easily pollutes human body; (4) some spraying mechanical is expensive, is unwell to common peasant household and uses.Especially for the closed environment that green house is such, existing application equipment and application method exacerbate the humidity of closed environment undoubtedly, infect the condition of creating again for germ.Therefore, developing new insecticide-applying way and device for administration of drugs, improve Pesticide use rate, reducing chamber humidity is the current problem needing to solve.
Summary of the invention
The purpose of this utility model is the defect for prior art, and provide a kind of self-priming Gasification at the negative pressure greenhouse device for administration of drugs, this device can realize stoste and spray, and significantly can not increase air humidity, is specially adapted to plastic greenhouse dispenser.
Self-priming Gasification at the negative pressure greenhouse of the present utility model device for administration of drugs comprises medicine-chest 1, liquid jet pipe 2, variable cross-section kidney-shaped pipe 3, crossover sub 4, fallopian tube 5, cfentrifugal blower 6, air inlet 7.The bottom of medicine-chest 1 is communicated with one end of liquid jet pipe 2, and the other end of liquid jet pipe 2 is communicated with the aditus laryngis place of variable cross-section kidney-shaped pipe 3.One end of variable cross-section kidney-shaped pipe 3 is air inlet 7, and the other end is connected with the osculum end of fallopian tube 5 by dress changing-over 4, and the big opening end of fallopian tube 5 is connected with the inlet end of cfentrifugal blower 6.
After operation principle cfentrifugal blower of the present utility model starts, drive gas to produce high-speed motion and produce pressure reduction, air is inhaled into from air inlet, the air sucked produces Venturi effect through variable cross-section kidney-shaped pipe, namely there is " negative pressure " phenomenon, liquid sprays from medicine-chest via liquid jet pipe under suction function, the liquid of ejection is broken up by high velocity air, carry out a Gasification at the negative pressure, liquid/air Mixture after gasification flows through dress changing-over head arrival fallopian tube and fully mixes, then cfentrifugal blower is sent to, second gasification is produced under centrifugal action, drop at blower outlet place continues broken gasification, and the ejection of gasification liquid is full of the whole confined space in greenhouse.
Using method of the present utility model is by liquid and water and pour medicine-chest into after diluting by the proportioning of 1:2.5-10, and the outlet of cfentrifugal blower being aimed at needs dispenser place, opens fan blower.
The beneficial effect that the utility model brings
(1) this device is by being combined by variable cross-section kidney-shaped pipe and centrifugal blower, achieve the negative pressure self-priming of liquid, without the need to optional equipment (Teat pipette), simplify device, use variable cross-section kidney-shaped pipe to carry out a Gasification at the negative pressure to liquid, the air-flow adopting centrifugal blower to produce carries out second gasification, gasification installation with between second gasification device with adopting fallopian tube to be connected, reduce pipeline to lose along stroke pressure, in order to avoid gasification liquid liquefies.
(2) this device realizes the gasification that stoste sprays, and is evenly spread in by agricultural chemicals in whole green house closed environment, significantly can not increase air humidity.
(3) agricultural chemicals after the gasification of this device spreads in the whole confined space of green house, directly can kill the noxious bacteria in green house in air and virus; Secondly, gasification agricultural chemicals can be attached on the steelframe of green house, plays the effect of kill bacteria and virus; In addition, gasification agricultural chemicals is little due to fogdrop diameter, and be improved at the adhesive rate of plant leaf surface, therefore its availability is improved, traditional spray mode agricultural chemicals availability only 20% ~ 30, and this device agricultural chemicals availability is brought up to 80%.
(4) this apparatus structure is simple, manufacture craft simple, cheap, achieves mechanical-electrical-hydraulic integration spraying, reduces labour intensity.
(5) starting switch of this device can be arranged on outside greenhouse, avoids the pollution of agricultural chemicals to human body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to the elaboration of the upper step of reason.
Self-priming Gasification at the negative pressure greenhouse of the present utility model device for administration of drugs comprises medicine-chest 1, liquid jet pipe 2, variable cross-section kidney-shaped pipe 3, crossover sub 4, fallopian tube 5, cfentrifugal blower 6, air inlet 7, one end of described liquid jet pipe 2 is communicated with the bottom of medicine-chest 1, the other end is located at the aditus laryngis place of variable cross-section kidney-shaped pipe 3, the inlet end of described cfentrifugal blower 6 is provided with fallopian tube 5, the osculum end of fallopian tube 5 is connected with variable cross-section kidney-shaped pipe 3 by dress changing-over 4, and the other end of variable cross-section kidney-shaped pipe 3 is air inlet 7.
