Description
Technical field
The present invention relates to flusher technical fields, and in particular to the spray head that one kind can backwash.
Background technique
With the rapid propulsion of urbanization, rural laborer's leakage is more serious, agricultural standardization, mechanization production
Key and trend as modern agricultural development.But it is standardized, mechanized manner is different from traditional field crop, Wu Fashi
Existing whole mechanical planting and harvesting, can only determine unified seeding row spacing, to realize part by way of artificial unwrapping wire
Mechanization spray, fertilising etc. management.
And crop field operation routine unwrapping wire, usually on the basis of track is crossed in confirmation, using lime or gypsum, curved waist
Mark a clearly white route on the ground along track, there are many drawbacks for such routine work mode.And it uses
When conventional spray head carries out unwrapping wire, larger particles lime or gypsum can block spray head, be unfavorable for the lasting progress of scribing line.
Summary of the invention
The purpose of the present invention is to provide the spray heads that one kind can backwash, existing using spray head progress crop field operation to solve
Conventional unwrapping wire is easy the problem of blocking.
The technical scheme to solve the above technical problems is that
A kind of spray head backwashed, comprising: connector and the adjustable nozzle being connected to respectively with connector and feed liquor group
Part；
Connector includes water outlet and water inlet end；The inside of connector is equipped with the exhalant canal of end connection, the first water inlet
Channel and the second intake tunnel；Exhalant canal extends to water outlet；First intake tunnel and the second intake tunnel all extend to
Water inlet end；The middle part of first intake tunnel is connected to the middle part of the second intake tunnel by return flow line；First intake tunnel and
Second intake tunnel is equipped with block valve between exhalant canal and return flow line；
Feed liquor component includes that isocon and the inlet tube being connected to the middle part of isocon, the first outlet tube and second go out
Liquid pipe, inlet tube is between the first outlet tube and the second outlet tube；The company of first outlet tube and the second outlet tube and isocon
The place of connecing is equipped with triple valve, and the first outlet tube and the second outlet tube are connected to simultaneously with the first intake tunnel and the second intake tunnel respectively
And first the inside of outlet tube and the second outlet tube be equipped with filter screen.
The present invention controls the flow direction of liquid by the open state of block valve and triple valve, to realize to filter screen reality
It now backwashes, prevents filter screen from being blocked by larger particles lime or gypsum.
When normal work, block valve is in open state, and triple valve is by the first outlet tube and the second outlet tube and feed liquor
Pipe connection, liquid enters isocon from inlet tube, then respectively enters the first outlet tube and the second outlet tube, in the effect of triple valve
Under, liquid will not be overflowed from the end of isocon, and liquid respectively enters after filtering in the first outlet tube and the second outlet tube
In one intake tunnel and the second intake tunnel, finally converges and flow to adjustable nozzle from exhalant canal.
When the filter screen blocking in the first outlet tube, the block valve in the first intake tunnel is closed, regulating three-way valve will
First outlet tube and inlet tube are truncated, and liquid will not be directly entered in the first outlet tube from isocon at this time, can only enter second
Outlet tube, and enter in the second intake tunnel, liquid shunts in the second intake tunnel, and a part is flowed into exhalant canal
In, another part is flowed into return flow line.Liquid flows to the first outlet tube from return flow line, and washes away in the first outlet tube
Larger particles lime or gypsum are separated with filter screen and are discharged from the end of isocon, realizes backwashing function by filter screen.
When the filter screen blocking in the second outlet tube, the block valve in the second intake tunnel is closed, regulating three-way valve makes
Second outlet tube is connected to the end of isocon, be can be realized and is rinsed to the filter screen in the second outlet tube.
Further, the link position of above-mentioned return flow line and the first intake tunnel and the second intake tunnel is equipped with chamfering.
Chamfering is arranged at the both ends of return flow line in the present invention, and liquid, can will be enough when the end of return flow line shunts
Liquid guide flow into return flow line, it is more thorough to the flushing of filter screen.
Further, above-mentioned return flow line is domed, the direction bending where return flow line towards exhalant canal.
When return flow line of the invention is bent beyond the direction of aquaporin, the both ends of return flow line are in Y type, facilitate liquid
Water conservancy diversion.
Further, the both ends open of above-mentioned isocon.
The both ends open of isocon of the present invention, for being discharged the liquid after rinsing, the lime or gypsum of larger particles from this
Place's discharge.
Further, the end of above-mentioned first outlet tube and the second outlet tube passes through sealing element respectively and connector sealing connects
It connects.
Sealing element of the invention can prevent liquid from the link position of the first outlet tube and the second outlet tube and connector
Leakage.
Further, above-mentioned sealing element is O-ring.
Further, above-mentioned filter screen is domed, the direction bending where filter screen towards isocon.
After filter screen bending of the invention, filter area is increased, larger particles lime or gypsum can be rolled to wedge angle position
It sets, improves the stopping state of filter screen, reduce the anti-wash number of spray head, extend spray head uses the time.
Further, the screen size of above-mentioned filter screen is 45 mesh.
The present invention has biggish screen size compared with conventional filtration net using the filter screen of 45 mesh, reduces filter screen and is blocked
Risk.
The invention has the following advantages:
(1) present invention controls the flow direction of liquid by the open state of block valve and triple valve, to realize to filtering
Net realizes backwash, prevents filter screen from being blocked by larger particles lime or gypsum.
(2) present invention uses curved filter screen, increases filter area, larger particles lime or gypsum can be rolled to point
Angle Position improves the stopping state of filter screen, reduces the anti-wash number of spray head, and extend spray head uses the time.
