Abstract
The utility model relates to a knapsack sprayer, it includes spray tank and water-spraying system, its main points are the cross joint in the spray tank, the one end of this cross joint is drawn forth from the spray tank, through gas-supply pipe and two-way alligator air bag intercommunication, the alligator air bag of saying is located in the sole half sole intermediate layer, the second end of cross joint passes through the check valve that admits air and connects the intake pipe, the third end passes through the feed liquor check valve and connects the liquid medicine pipe, the fourth end is connected with water-spraying system through going out the liquid check valve. The utility model discloses rational in infrastructure, easy and simple to handle, can realize the pressurization spraying through the operator walking, the working face is wide, and labor efficiency is high.
Description
The utility model relates to a kind of knapsack sprayer.
The knapsack sprayer of prior art generally all is that manual pump is set on spray tank, to the spray tank inflation, produces pressure, realizes medicine liquid spray.This knapsack sprayer, atomisation pressure are stable inadequately, and be bigger during beginning, later on can be more and more littler, and when pressure does not reach spraying when requiring, must break-off, row inflation pressurization just can work on inefficiency again.In addition, existing knapsack sprayer mostly is single cover spraying system, is single shower nozzle, and the spraying working face is little, and efficient is low.
But the purpose of this utility model provides a kind of continuous operation, novel knapsack sprayer that nebulization efficiency is high, thereby overcomes the above-mentioned deficiency of existing in prior technology.
The purpose of this utility model is to improve realization on the basis of existing technology, it comprises spray tank and spraying system, its main points are to be equiped with four-way connection in the spray tank, one end of four-way connection is drawn from spray tank, be communicated with a two-way crocodile typed air sac by appendix, said bidirectional crocodile typed air sac is arranged in the half sole interlayer; Second end of four-way connection connects air inlet pipe by a breather check valve, and the upper end of this air inlet pipe is positioned at more than the soup face; The 3rd end of four-way connection is communicated with drug liquid tube by a feed liquor check valve, and the 4th end is connected with spraying system by the fluid check valve.
Accompanying drawing is a structural representation of the present utility model
Below in conjunction with accompanying drawing the utility model is elaborated:
With reference to the accompanying drawings, 12 is spray tanks among the figure, and four-way connection 9 is housed in it, and an end of this four-way connection 9 is drawn from spray tank 12, is communicated with a two-way crocodile typed air sac 2 by appendix 6, and said bidirectional crocodile typed air sac 2 is arranged in the half sole interlayer of sole 1; Second end of four-way connection 9 connects air inlet pipe 11 by breather check valve 10, and the upper end of said air inlet pipe 11 is positioned at more than the soup face; The 3rd end of four-way connection 9 is communicated with drug liquid tube 4, the four ends by feed liquor check valve 5 and links to each other with spraying system 3 by fluid check valve 8.
In the use, when foot-operated following time, compressing bidirectional crocodile typed air sac 2, the air in the air bag 2 enters four-way connection 9 by appendix 6, forms malleation, and this moment, breather check valve 10 and feed liquor check valve 5 were closed, and fluid check valve 8 is opened; When lifting pin, crocodile typed air sac 2 loses pressure, opens return-air under the effect of its spring, so that make four-way connection 9 form negative pressure, fluid check valve 8 is closed at this moment, and breather check valve 10 is opened air inlet, and feed liquor check valve 5 is opened and entered soup; When riding following time once more, four-way connection 9 becomes malleation again, and breather check valve 10 and feed liquor check valve 5 are closed, fluid check valve 8 is opened, and inhaled air and soup are pressed into spraying system 3 in the time of will lifting pin, like this, along with operator's walking, can realize the operation of spraying continuously.
For improving the stability of its spraying operation, prevent that spraying is interrupted when lifting pin, on the said spraying system 3 voltage stabilizing air tank 7 can be set.
For preventing that spray tank 12 bottom sediments from entering pipe-line system by drug liquid tube 11, blocking pipe and cause check valve malfunctioning, the end of said drug liquid tube 4 can also be provided with a filter.
Spray working face for enlarging, said four-way connection 9 can be two, and second connection is identical with first.So then can there be two groups of spraying systems to work simultaneously, increase work efficiency greatly.
The utility model modern design, rational in infrastructure, need not inflate pressurization separately, the operator can provide atomisation pressure when walking, the duplexed system continuous operation, simple to operate, working face is big, the nebulization efficiency height.
