Description
Technical field
The present invention designs agricultural machinery technological field more particularly to a kind of air curtain for efficient spray machine.
Background technique
Efficient spray machine generally comprises a longer bracket, is provided with multiple injection spray pipes on the rack, and these injection spray pipes
It needs to be connected by air curtain with the blower of spraying machine, existing air curtain includes an air hose, and one is arranged on the side wall of air hose
Axial wind groove, air curtain in use, in entire wind groove all can air draft, cause wind-force to waste, wind-force output is not concentrated, and wind pressure is small, is used
Have an impact on spraying machine to pesticide supplying effect.Cotton is the Important Economic crop in China, and common spray bar type spraying machine is pure to lean on fluid power
Spray, medicine drip the dense canopy that can not penetrate cotton, the medical fluid deposition of canopy middle and lower part downwards above Cotton Canopy for atomization
Seldom, the prevention and control of plant diseases, pest control is ineffective.
If Chinese patent CN202364708U discloses a kind of wind curtain type suspension spraying machine, mainly by hanger bracket and spray boom group
At the spray boom is vertical folding spray boom, and spray boom is arranged on hanger bracket by profiling frame, and the principal arm of spray boom passes through swing arm oil
Cylinder stretching, extension and folding, the support arm of spray boom passes through the linkage wirerope stretching, extension secretly set and folds, after hanger bracket is suspended on tractor
Portion, is equipped with a spray pump and a hydraulic pump on hanger bracket, and spray pump and hydraulic pump are with the output shaft of tractor rear
Power is equipped with several nozzles on spray boom, and pressure medical fluid is pipelined to each nozzle by spray pump makes medical liquid atomizing, outstanding
It is additionally provided with blower and main air curtain on hanger, gushing arm air curtain is equipped on spray boom, hydraulic pump passes through the hydraulic horse of petroleum pipeline and blower
Up to connection, hydraulic motor drives the fan blade rotation of blower, and the wind-force that fan blade generates is by main air curtain and gushing arm air curtain each
Ducting outlet at nozzle screws out, and the medical fluid that wind-force wraps up in atomization sprays to plant.Spray pump is diaphragm pump, is also set on hanger bracket
There is air-cooled oil storage cylinder, hydraulic pump is connected by the hydraulic motor of petroleum pipeline and air-cooled oil storage cylinder and blower.The shortcomings that structure, is:
Spray boom is longer, only takes into account the efficiency of spray, does not account for the effect of spray, such as bollworm, aphid in cotton planting
With worm's ovum mostly at the back side of blade, if the apparent work for reducing insect pest would not be played by carrying out spray using this structure
With, and do not account for that the plantation interval between Different Crop is different, if be spaced between the crop of plantation it is excessive or it is too small
It is uneven to will lead to sprinkling.
For another example Chinese patent CY2219018Y disclose it is a kind of largely possess with current rural area it is 20 horsepowers below small by four
High-efficient, wide adaptation range the cotton sprayer that wheel tractor uses.For complete goal of the invention and design with 20 horses
The rack of the matched cotton sprayer of power tractor with small four wheels below is made of bearing support and sprinkling frame, bearing support and small four-wheel
The towing point and hitch point of tractor connect into stable trifilar suspension, and sprinkling frame is cantilevered truss structure, are hinged on bearing
Frame two sides have the double-act-ing hydraulic J-Horner being connected with the hydraulic pressure system of tractor to spray frame to rise and fall between bearing support and sprinkling frame.
The spray tank of spraying machine is born on the bearing support of tractor rear wheel protecting cover and cotton sprayer.The infusion pump of spraying machine is and drags
The connected diaphragm pump of the power output shaft of machine drawing, using the anti-drip shower nozzle of limited pressing spring and stainless steel spray nozzle sheet.The structure
The shortcomings that be: do not account for the blade reverse side of sprinkling cotton, without the pest problem of practical solution cotton, and the structure is only fitted
For the pesticide spraying of cotton, be not suitable for the sprinkling of other crops pesticides, practicability is low.
