Embodiment
Below in conjunction with accompanying drawing and example, the present invention will be further described.
As shown in Figure 1, 2, 3, the present embodiment is coerced the directed pollinating device of oscillatory type hybrid rice aspiration and is mainly comprised transmission mechanism and pollination mechanism two large divisions.Pollination mechanism comprises Dang He mechanism and dusts mechanism.
Transmission mechanism is driven by motor 24, and motor 24 can be the direct current generator of 500w, and rated speed is 500r/min.It is powered by storage battery 15.
Motor 24 connects a worm type of reduction gearing 1, to adjust rotating speed.Worm type of reduction gearing 1 comprises worm screw 51 and worm gear 52.Worm screw 51 one end connects the driving shaft of motor 24 by motor coupler 23, the other end connects bevel pinion 22.Worm gear 52 connects head sprocket 27(as Fig. 3), head sprocket 27 is connected from sprocket wheel 37 by chain, is positioned at the land wheel 28(of pollination machine front end as Fig. 2 from sprocket wheel 37 by wheel shaft 38 through sprocket wheel shaft coupling 34 connection), advance to drive pollination machine.Pollination machine rear end is provided with handrail 10 and universal wheel 18.Handrail 10 controls direction for people, and universal wheel 18 matches with land wheel 28.
Above-mentioned bevel pinion 22 engages bevel gear wheel 14.Bevel gear wheel 14 connects rotating shaft 12, and rotating shaft 12 is connected to push rod 45(simultaneously see Fig. 4 to Fig. 6 by the switching mechanism that crank 25, slide block 5, guide rod 26 form), the rotary motion of rotating shaft 12 is converted to the straight reciprocating motion of push rod.Specifically, crank 25 one end is connected to rotating shaft 12, other end connection sliding block 5 bottom, and slide block 5 top is contained in slide block guide groove 57.Push rod 45 roughly in H-shaped, comprises fork 54 and is positioned at fork 54 two ends and the pushing part 56 be parallel to each other, and fork 54 can only swing by fork guide groove 55 restriction.Pushing part 56 end is provided with the knuckle of an infolding, to avoid injuring paddy rice.Be provided with spigot nut 53 in the middle part of fork 54, on guide rod 26, correspondence is provided with spigot nut guide groove 58, to increase the degree of freedom of fork 54 at fore-and-aft direction.Said structure forms Dang He mechanism.During operation, rotating shaft 12 drives crank 25 to rotate, and then drives guide rod 26 to swing by slide block 5, and guide rod 26 drives again push rod 45 to do left and right straight reciprocating motion, and its pushing part 56 knocks the stem of paddy rice male parent gently, and paternal pollen is kicked up certain altitude.
Mechanism of dusting comprises inlet scoop 46, pollination tube 8 and the mouth 44 that dusts.After pollen envelop is kicked up, then suck in pollination tube 8 by blower fan 9 by inlet scoop 46, pollen is delivered to along pollination tube 8 mouth 44 that dusts by the air-flow that blower fan 9 produces, and pollen just spills to female parent in the mode of freely falling body subsequently.
The present invention coerces the directed pollinating device of oscillatory type hybrid rice aspiration and compares manpower pollination, and labour intensity is little, and pollination efficiency is high.Especially pollination quality is good, this is because: first is namely adopt namely to pollinate, and pollen quality is guaranteed, and traditional collection and pollination are proceeded in two phases, the pollination time of prolongation, and pollen quality is influenced; The second, maternal top can effectively be carried and be delivered to pollen, and uniform pollination is good, and pollination Objective is strong, and the curved distribution of pollinating of relatively conventional pneumatic type wants uniformity much better; 3rd, coerce the male parent stem stalk property entered and vibrate spreadability positioning acquisition again, pollen collecting is effective, and it is few that pollen falls grain loss, improves the quality of pollen pollination.Meanwhile, this programme mechanism design is simple, is convenient to manufacture processing.
