Embodiment
As shown in Figures 1 to 6, a kind of change vapour-pressure type accurate nest eye seeds discharging box, comprises seed wheel, plants case, discharging tube and dividing potential drop box, wherein:
Seed wheel 3, seed wheel is disc wheel.The wheel rim of wheel body is provided with several nest eye 10 in uniform spacing distance.The circle centre position of wheel body is provided with the regular hexagon hole 31 connected with power transmission shaft 6.Cannelure 32 is provided with between the wheel rim and wheel hub of side.The bottom of each nest eye is communicated with cannelure by respective ventilation hole.The upper end wheel rim of seed wheel is positioned at the bottom opening place of kind of case 4, in the bottom opening place that it produces kind of case, be provided with kind of brush 1.The lower end wheel rim of seed wheel is positioned at the upper end of discharging tube 7.
Dividing potential drop box 5, dividing potential drop box is hollow disc shape parts.Space between wheel rim and centre bore is separated to form two sector spaces by two pieces of dividing plates 14.Each sector space is connected with the malleation source of the gas of outside and negative pressure source of the gas respectively by two pipelines 11,12 of being positioned at box body one side, forms zone of positive pressure 8 and negative pressuren zone 9.Be provided with flangeway 13 at the wheel rim of disk body, this flangeway is identical with two inner sector spaces, and correspondence is separated into zone of positive pressure and negative pressuren zone part.Two sections of flangeways have several through hole to communicate with between two sector spaces.Dividing potential drop box is socketed on the wheel hub of seed wheel, is embedded in the cannelure of seed wheel.The zone of positive pressure of dividing potential drop box originates in the edge of discharging tube, terminates in the bottom opening place of kind of case.
Described dividing potential drop box zone of positive pressure space and the volume ratio in space, negative pressuren zone are 9: 10.Described positive source of the gas the pipeline that provides is communicated with the exhaust outlet of air exhauster by conduit, provides a pipeline in angrily source to be communicated with the air inlet of air exhauster by conduit.
The seed wheel 3 that the utility model adopts static kind brush 1, kind case 4, discharging tube 7 and rotates.The layout of power transmission shaft 6 is identical with traditional seeding unit.Dividing potential drop box is static element relative to kind of a case, is socketed on the wheel hub of seed wheel, is embedded in the cannelure of seed wheel.The zone of positive pressure 8 of dividing potential drop box originates in the edge of discharging tube 7, terminates in the bottom opening place of kind of case 4.
During work, power transmission shaft 6 drives seed wheel 3 to rotate, and the nest eye 10 on seed wheel wheel rim is connected with positive pressure air and negative pressure air respectively when turning to zone of positive pressure 8 and the negative pressuren zone 9 of dividing potential drop box.Assuming that nest eye 10 from zone of positive pressure 8 clockwise in kind of case 4 rotate, when proceeding in kind of case 4, nest eye 10 is connected with the negative pressure air of 11 li, pipeline, suck seed 2, when being rotated further kind of brush 1, unnecessary seed is brushed off by kind of brush 1, nest eye 10 is loaded with a seed and is rotated further, when this nest eye 10 enters the top of discharging tube 7, connect with the positive pressure air of 12 li, pipeline, seed is blown into discharging tube 7; Nest eye 10 continues to detour, and before entering kind of case 4 again, nest intraocular always has positive pressure air to blow out, and the foreign material sucked when inhaling and planting in nest eye are constantly blown out.When this nest eye 10 screws in kind case 4, connect with negative pressure air again, enter the working cycles that next negative pressure inhales kind, malleation seeding.
In a word, the utility model can shorten and fills kind of a time to nest eye, reduces the infringement of seed and the good advantage of result of use, can promote the use of.
