Abstract
The present invention relates to a novel knapsack type sprayer for spraying pesticide liquor to plants. The novel knapsack type sprayer is mainly composed of a pesticide liquor box, a miniature gasoline engine, a flexible shaft, a gear pump, an axial flow fan, a liquid outlet pipe, a spray pipe, etc. The novel sprayer has the advantage of high utilization rate of wind energy, large wind quantity, far spraying range, good atomizing quality of the pesticide liquor, good adhesion property and control efficiency on plant, compact structure, flexible operation, and no scraping or carrying damage to plants. The novel sprayer can be widely used for the pest control of farm crops, fruit trees and gardens in large area, the sanitary epidemic prevention and environmental protection of towns, and the disinfection and the sterilization of storage spaces, large and medium hermetic spaces and fowl feeding plants. The novel sprayer has favorable economical benefit and social benefit.
Description
The present invention relates to a kind of novel knapsack sprayer that is used for plant is carried out medicine liquid spray.
Domestic and international existing knapsack sprayer generally all adopts miniature gasoline engine to be used as power to connect by hard axle and drives small-sized liquid pump or centrifugal blower carries out medicine liquid spray work.Structurally, it is installed gasoline engine, centrifugal blower or parts such as liquid pump, spray tank concentratedly on the frame of spraying machine, and its sprinkler part is portable airduct or spray boom.A kind of " knapsack sprayer-duster " shown in the annex 1 of the present patent application provided a kind of typical structure of this spraying machine.This spraying machine is because sprinkler part airduct pipeline is long, and it is thick and stupid, long pipe runs can cause bigger wind loss, influenced the service behaviour of spraying machine, make the medical liquid atomizing quality of ejection low, the tack on plant is poor, has reduced drug effect, simultaneously, long airduct pipeline has plant in the process of operation and scrapes, the band effect, so that plant produced in various degree damage; Operate also very dumb; And, it is to be undertaken by the static pressure of blower fan generation and the difference in height between spray tank liquid level and the interior liquid outlet of jet pipe that the soup of this spraying machine is carried, when vertical hydrojet, can cause the liquid spraying quantity inequality, even situation that can not fluid, be difficult to adapt to the orchard and need carry out vertical operating environment of spraying with gardens etc.In addition, this spraying machine is because the rotation speed of fan height, thereby noise height, vibration are big.
Another kind of spraying machine adopts miniature gasoline engine directly to link to each other with liquid pump, and its sprinkler part is the hand-held spray boom, and the problem of existence is that operating efficiency is low.(see attached see 2) also has a kind of spraying machine, and its miniature gasoline engine directly links to each other with axial flow blower, is not with liquid pump, and whole facility are backpack, and it is sprayed after one's death to the operator, and operation is very dumb.
The object of the present invention is to provide a kind of need not airduct, volume is little, air quantity is big, far firing range, noise is low, vibration is little, the medical liquid atomizing quality is good, the novel knapsack sprayer that tack is strong, operating efficiency is high.
The present invention includes with the prior art is the spray tank 1 of characteristics, be positioned at soup 1 bottom and coupled frame 2 mutually, be positioned at the gasoline engine 3 on the frame 2, the pipette 4 that links to each other with spray tank 1 and be the flexible axle 5 of characteristics with the invention, circular casing 6, guard shield 7, gear pump 8, axial flow blower 9, drain pipe 10, jet pipe 12, wherein, axial flow blower 9 and gear pump 8 are installed in the circular casing 6 coaxially with upper-lower position respectively, guard shield 7 is positioned at casing 6 bottoms, the two ends of flexible axle 5 link to each other with the turning cylinder of gasoline engine 3 and the pump shaft of gear pump 8 respectively, the pipette 4 of being drawn by spray tank 1 links to each other with the import of gear pump 8, the two ends of drain pipe 10 link to each other with the outlet of gear pump 8 and an end of jet pipe 12 respectively, one end of jet pipe 12 is positioned on the center on casing 6 tops, shower nozzle 13 is housed on it, the other end of jet pipe 12 is positioned at outside the casing 6, which is provided with feed flow switch 11.
This novel knapsack sprayer has been broken through the traditional structure of existing knapsack sprayer and the kind of drive, it is simple in structure, volume is little, easy to operate, the powerful air stream that prior axial flow blower produces directly acts on the droplet that is ejected, make utilization ratio of wind energy obtain maximum the raising, thereby it is big to make it have an air quantity, far firing range, atomization quality is good, tack is strong, total noise of centrifuge is low, vibrate advantages such as little, flexible operation, can be widely used in the prevention and control of plant diseases, pest control in large tracts of land crops and fruit tree, gardens and the health and epidemic prevention and the environmental protection in cities and towns; Using motor instead is power source, can be used for storing in a warehouse, desinsection, the sterilization of big-and-middle-sized hermetic type space and its feeding field, has good economic and social benefit.
Below in conjunction with accompanying drawing narration embodiments of the invention.
Fig. 1: structure principle chart of the present invention.
As shown in Figure 1, feed flow is loaded in the spray tank 1, and when gasoline engine 3 rotated, power was passed to gear pump 8 by gasoline engine by flexible axle 5, because axial flow blower 9 and 8 coaxial connections of gear pump, they are all started.After the gear pump work, soup enters gear pump through pipette 4, flows to jet pipe 12 by drain pipe 10 again after the gear pump supercharging, opens the feed flow switch 11 on the jet pipe 12, and the soup that is pressurized sprays from shower nozzle 13 with fine fog; Meanwhile, the powerful air-flow that is produced by axial flow blower 9 further atomizes the soup of ejection, and is blown on the target that needs the spray medicine.Because the air-flow that axial flow blower produces has certain spin intensity, cause the leaf that is sprayed plant to produce and stir, improve soup and on plant, adhered to quality, and then improved prevention effect.
The present invention has structurally removed the airduct that is used to carry the air-flow that is produced by blower fan in the prior art, this not only makes complete machine structure compacter, alleviated spraying machine scraping in the operation greatly to plant, the band damage, the power consumption of blower fan is reduced, and axial flow blower of the present invention can be realized effective spraying under lower rotating speed, and the reduction of rotating speed has reduced the noise and the vibration of spraying machine, help energy-conservationly, improved operator's operating environment simultaneously.
Power source of the present invention also can adopt diesel engine, motor, tractor, automobile etc., replacements such as the also available centrifugal pump of used gear pump, peripheral pump, piston pump, plunger displacement pump, membrane pump, and used blower fan also can adopt centrifugal blower.
Utilize structure of the present invention, also it can be changed into stretcher type, cart type, suspension type, towed and vehicular spraying machine, to adapt to the needs of different work environment.
