Abstract
A kind of pesticide spraying volume control device, including spray head and liquid feeding pump further include a screw press conveyer；The spray head includes inlet tube, and inlet tube is connected to the liquid outlet of liquid feeding pump；The screw press conveyer includes level-one helical blade and deuterostrophies blade, and the screw pitch of the level-one helical blade is greater than deuterostrophies blade, and liquid stream passes through deuterostrophies blade outflow screw press conveyer after passing through level-one helical blade；The liquid outlet of screw press conveyer is connected to by bend pipe with inlet tube.The device can more effectively control liquid flow, improve spraying efficiency.
Description
Technical field
The utility model relates to a kind of flushers of pesticide.
Background technique
The existing pesticide spraying flow control amplification in ground is single, and only by directly controlling flow, such as control pump or valve come
Flow control amount.There are many very unfavorable when requiring for sprinkling for this mode.Such as when needing low discharge, but wide range, concentrate spray
It basically can not just be controlled when exit point.
Utility model content
The purpose of this utility model is to provide a kind of pesticide spraying volume control devices.
To achieve the goals above, the utility model includes spray head and liquid feeding pump, further includes a screw press conveying
Device.
The spray head includes inlet tube, and inlet tube is connected to the liquid outlet of liquid feeding pump；
The screw press conveyer includes level-one helical blade and deuterostrophies blade, the spiral shell of the level-one helical blade
Away from deuterostrophies blade is greater than, liquid stream is conveyed after passing through level-one helical blade by deuterostrophies blade outflow screw press
Device；
The liquid outlet of screw press conveyer is connected to by bend pipe with inlet tube.
It further, further include high-pressure air source, high-pressure air source is to spray head air inlet.
Further, level-one helical blade and deuterostrophies blade include hard portion and flexible part, and flexible part is fixed on
Hard portion outer periphery is directly contacted with screw press conveyer object inner wall.
Further, the screw pitch of the deuterostrophies blade is the half of level-one helical blade screw pitch.
The beneficial effects of the utility model are that it is possible to effectively improve the validity of flow control, then flow control is same
When, different use environments are adapted to, spraying efficiency is improved.
Detailed description of the invention
Fig. 1 is utility model diagram.
Specific embodiment
Utility model is described in detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of pesticide spraying volume control device, including spray head 10 and liquid feeding pump 20.It further include a spiral shell
Revolve pressurized delivered device 30.
The spray head 10 includes inlet tube 11, and inlet tube 11 is connected to the liquid outlet of liquid feeding pump 20；
The screw press conveyer 30 includes level-one helical blade 31 and deuterostrophies blade 32, the level-one helical-blade
The screw pitch of piece 31 is greater than deuterostrophies blade 32, and liquid stream is flowed out after passing through level-one helical blade 31 by deuterostrophies blade 32
Screw press conveyer 30；
The liquid outlet of screw press conveyer 30 is connected to by bend pipe 12 with inlet tube 11,
It further include high-pressure air source 40, high-pressure air source 40 is to 10 air inlet of spray head.High-pressure air source 40 can be can also be with by air pump
It is manually inflator, according to the selection of the different adaptability of application apparatus.
Level-one helical blade 31 and deuterostrophies blade 32 include hard portion and flexible part, and flexible part is fixed on hard portion
Outer periphery is directly contacted with 30 object inner wall of screw press conveyer.
The screw pitch of the deuterostrophies blade 32 is the half of 31 screw pitch of level-one helical blade.
Pressurized treatments can be carried out to liquid stream by using screw press conveyer 30, when needing the constant injection pressure of flow
When increase, by valve or control screw press conveyer 30 motor speed and liquid feeding pump operating power come
Adjustment allows most of liquid stream to enter liquid feeding pump by screw press conveyer 30.
High-pressure air source then can be used when needing to further decrease flow, pour liquid stream, while not influencing to spray pressure
Reduce fluid flow.
When needing enlargement discharge to reduce pressure, then the workload of high-pressure air source and screw press conveyer 30 is reduced.
Flow so can be more effectively adjusted, while unused use environment can be better conformed to flow and jet pressure
The demand of power.Use scope is wider.
The device is changeable, and device volume is big, then can be used on irrigation sprinkler, small to can be used for single pesticide spray
It spills in equipment, practicability and effectiveness is applied widely.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for ability
For field technique personnel, various modifications and changes may be made to the present invention.It is all in the spirit of the present invention and principle, done
Any modification, equivalent substitution, improvement and etc., should be included within the scope of protection of this utility model.
