(3) draw box mechanism is planted: plant case, plant box bracket, base plate; Plant box bracket to be welded on the downside of kind of case, be used for fixing kind of a case; Base plate is welded on kind of a box bracket side, for fixing blower fan;
(4) transmission system: land wheel, sprocket wheel, ground wheeling rack, mud guard; Land wheel is arranged on ground wheeling rack; Land wheel and sprocket wheel, mud guard coaxial rotation; Mud guard is welded on ground wheeling rack, prevents from sprocket wheel is stained with earth;
Case study on implementation:
During work, the trifilar suspension structure of seed broadcaster by connecing hangers, articulated pin forms trifilar suspension with tractor and is connected, and adopts the three-point hitch of hydraulic control, can output hydraulic pressure energy, the lifting of manipulation farm machinery, can control seed broadcaster like this and broadcast sowing in place.
The power of tractor changes direction of transfer by card gear, and by transmission of power to belt driver 12, by V belt translation by transmission of power fan 10, the wind-force that blower fan 10 produces arrives feed injector 26 along pipe.In tractor advance process, land wheel 8 constantly rotates, and land wheel 8 passes through chain and sprocket driving device 5 by transmission of power to water jacket wheel shaft 15, and water jacket wheel shaft 15 rotates and both drives the sleeve 22 of outer groove-wheel 19 and outer groove-wheel both sides to rotate, and also drives shaft 14 to rotate by gear drive; Outer groove-wheel 19 rotates and seed is delivered to discharging tube 17 from kind of case 2, and shaft 14 rotates and prevents seed from above outer groove-wheel 19, forming accumulation; Collection kind device 13 sidewall between outer groove-wheel 19 and shaft 14 is provided with baffle holes, and the mobilizable level of small front apron 21 inserts baffle holes; When needs increase amount of seed metering, by small front apron 21 kind of device inner horizontal outwards movement along outer groove-wheel 19 axle from collection, effective active length of outer groove-wheel 19 increases, and the grain weight entering discharging tube 17 increases; When needs reduce amount of seed metering, moved kind of device inside along the axial level of outer groove-wheel 19 to collection by small front apron 21, effective active length of outer groove-wheel 19 reduces, and the grain weight entering discharging tube 17 reduces; Seed in discharging tube 17 relies on gravity and negative pressure to enter wind and send pipe charging aperture 25.The wind-force at feed injector 26 place is by the seed at charging aperture 25 place, and along straight tube to blowing up, the process that seed outwards blows is through pleated tube 24, and seed mixing is more even; Pleated tube diameter 5mm less of straight tube diameter, can play the effect of supercharging, and the seed speed of service is accelerated; Mix and the seed accelerated of movement velocity through bend pipe, arrive nozzle 23, nozzle 23 adopts the flat-shaped sector structure of uiform section area gradual change type, reaches and sows seeds evenly and increase the object of broadcasting sowing fabric width.
Tractor dynamic power is passed to blower fan by belt driver by this seed broadcaster, solve that wind spraying aid type sead feeder weight is large, high in cost of production problem, outer groove-wheel, under the prerequisite meeting Seeding Uniformity, increases outer groove-wheel diameter, reduce seed damage ratio, improve operating efficiency.Innovation of the present invention, is the restriction overcoming traditional paddy machinery seeding method, adopts seed broadcaster to carry out the mechanical planting of paddy rice.Use seed broadcaster to carry out operation, improve operating efficiency, and can sow evenly, have good application market.
