Bar, air-flow elevating lever lower section connection electric blower, the caliber of L-type pipe vertical portion is gradually reduced from down to up, in this section pipe
The center side wall in road is provided with through hole, and through hole is connected by flexible pipe with liquid storage bag, installing auxiliary liquid in liquid storage bag；It is described auxiliary liquid by
The raw material configuration of following weight portion is formed：10000 parts, ammonium molybdate 2-5 parts, urea 5-8 parts, sucrose 10-15 parts of water；
The L-type pipe lateral part side is provided with gas blowout mouthful, and L-type tube wall side is provided with rectangle dead slot, water is provided with rectangle dead slot
The side of the dynamic wheel piece of flat turn, operationally, wheel piece part is located in L-type pipe, and wheel piece is by motor by transmission shaft driven, motor
Storage powder pot bottom corresponding with wheel piece is fixed on by fixing device, the irregular burr of piece peripheral distribution is taken turns, motor is by electricity
Line is by control device control.
Used as further improvement of these options, the wind speed when electric blower works is 0.8-1m/s, can be
Pollen is blown out L-type pipe by auxiliary liquid in the case of mixing with pollen, completes pollination operation.
As further improvement of these options, vibrator is installed on the storage powder tank lateral wall, can be prevented effectively from
Or blocking hardened when pollen is transmitted inside device；The vibrator controls start and stop by electric wire by controlling switch.
Used as further improvement of these options, the liquid storage bag is made up of modeling prepared material, when in use closed sealing,
It hang on air-flow elevating lever side.
Used as further improvement of these options, the gas blowout mouthful is horn opening, and inner side is uniformly provided with multiple and inclines
Oblique wedge-shaped guide card, can be such that pollen is uniformly sent forth from gas blowout mouthful.
When in use, electric blower produces upward air-flow to pollination device in the present invention, air-flow in L-type pipe vertical portion,
Because caliber shrinks, wind speed increases suddenly, and the through hole of inner-walls of duct forms low pressure, and the auxiliary liquid in liquid storage bag receives outer
The extruding of portion's atmospheric pressure, makes to aid in liquid to be mixed into upward air-flow on a small quantity, as air-flow mixes with the pollen in L-type pipeline,
Sprayed by gas blowout mouthful, be mixed with the pollen weight penalty of auxiliary liquid, under the air velocity of 0.8-1m/s, the pollen of ejection can be made
It is scattered on female post near gas blowout mouthful, is favorably improved the success rate of pollination.
Whole device is made of light weight material, is easy to hand-held.
The present invention has advantages below compared to existing technology：Whole device is rational in infrastructure, using gas pressure, will aid in liquid
In press-in L-type pipeline, mix with pollen as air-flow drives, the device reduces the labour intensity of workman, is easy to operation, realizes
Long handle aloft, large-scale operation, simultaneously because the effect of auxiliary liquid, after pollen is fallen on female post, pollination rate is significantly
Improve, using the method pollinate after pear tree percentage of fertile fruit reached 31.25%, improve while labour intensity is alleviated through
Ji benefit, is suitable to promote the use of.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is right view of the invention.
Fig. 3 is top view of the invention.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As illustrated in fig. 1-3, a kind of pollination device for improving pear tree pollination rate, including storage powder tank 1, is provided with storage powder tank 1 and passes through
The L-type pipe 2 of the bottom surface of storage powder tank 1 and side is worn, the bottom of L-type pipe 2 connects telescopic multi-section type air-flow elevating lever 3, air-flow lifting
