Description
(1) technical field
The present invention relates to a kind of wind spraying aid type rice seed broadcaster, the seed broadcaster using particularly to paddy rice field, a kind of suspension type nonirrigated farmland.
(2) background technology
Paddy rice is one of topmost cereal crops of China, nearly 200,000,000 tons of paddy total output, accounts for the 40% of whole nation total grain output, account for that world's paddy always produces 35%, paddy average per unit area yield 6.21 ton/hectare, there is the people of nearly 60% in China with rice as staple food, annual directly 1.3 hundred million～1.4 hundred million tons of rice of consumption.In order to meet Rice Cropping requirement, the seeder that research is suitable for paddy rice agronomic characteristics is an urgent demand of peasant, is also the effective way advancing Rice Production mechanization of agriculture.
China's existing direct sowing of rice machinery, mostly use external recessing, external recessing has that simple in construction, Comparision be reliable and the advantage such as seeding is easy to adjust, but this feed mechanism for seed is during seeding, sheave groove forces seeding, makes seed flow be pulsation, and discharge capacity has pulsation phenomenon, seeding is uniformly poor, and seedling-damaging rate is high.The now external increasing wind spraying aid type feed mechanism for seed that uses, sowing line number is many, sown scope width, and injuring-free seed can be broadcast bud kind, but existing feed mechanism for seed structure is complicated, and noise is big, and cost is high.And Rice Seed Surface has a lot of prickle and rice husk is easy to fall off, the process such as on agronomy, live front requirement is soaked seed, broken chest shows money or valuables one carries unintentionally, even sprout so that paddy rice seeding is higher to hindering the requirement of the problem of kind.Therefore, research and develop one and can reduce rice paddy seed seedling-damaging rate, again can be cost-effective and sow uniform seeder, China's Rice Production is significant.
(3) content of the invention
In order to solve the problems referred to above, the invention provides a kind of wind spraying aid type rice seed broadcaster, this seed broadcaster had both overcome the high problem of tradition outer groove-wheel seedling-damaging rate, also solved that existing wind spraying aid type sead feeder weight is big, high in cost of production problem, improve operating efficiency, have good application market.
A kind of wind spraying aid type rice seed broadcaster, including metering system, blast system and kind case；

Present invention is mainly used for broadcasting sowing of the wet kind of nonirrigated farmland paddy rice, the device providing according to the present invention, below with reference to Fig. 1, the 2nd, the 3rd, 4 operation principle that the design is described.The power supplying apparatus of this seed broadcaster can use tractor.
As shown in Figure 1,2,3, 4, the present invention is formed by with lower part；
(1) metering system: outer groove-wheel, sleeve, water jacket wheel shaft, shaft, gear wheel, little gear, small front apron, collection kind device, discharging tube, bearing and bearing block；Shaft and water jacket wheel shaft are arranged on collection kind device by bearing and bearing block respectively；Outer groove-wheel and sleeve are arranged on water jacket wheel shaft by bonded；Gear wheel is arranged on shaft by bonded；Little gear is arranged on water jacket wheel shaft by bonded；Small front apron is arranged in the baffle holes of collection kind device；Discharging tube is welded on the downside of collection kind device；
(2) blast system: blower fan and wind send pipe；Wind send pipe to weld together with discharging tube；Blower fan send pipe to be connected by pipeline with wind；
(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, is used 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 rotates coaxially with sprocket wheel, mud guard；Mud guard is welded on ground wheeling rack, prevents from being stained with on sprocket wheel earth；
Case study on implementation:
During work, the trifilar suspension structure of seed broadcaster by connecing hangers, articulated pin and tractor form trifilar suspension and be connected, the three-point hitch of employing hydraulic control, can output hydraulic pressure energy, the lifting of manipulation agricultural machinery and implement, so can control seed broadcaster and broadcast sowing in place.
The power of tractor changes direction of transfer by card gear, imparts power to belt driver 12, imparts power to blower fan 10 by V belt translation, and the wind-force that blower fan 10 produces reaches feed injector 26 along pipe.During tractor advances, land wheel 8 constantly rotates, and land wheel 8 imparts power to water jacket wheel shaft 15 by chain and sprocket driving device 5, 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 drives shaft 14 to rotate also by gear drive；Outer groove-wheel 19 rotates and from kind of case 2, seed is delivered to discharging tube 17, and shaft 14 rotates and prevents seed from forming accumulation above outer groove-wheel 19；Collection kind device 13 sidewall between outer groove-wheel 19 and shaft 14 is provided with baffle holes, and small front apron 21 is mobilizable is horizontally inserted baffle holes；When needs increase flow rate, being displaced outwardly small front apron 21 from collection kind device inner horizontal along outer groove-wheel 19 axle, effective active length of outer groove-wheel 19 increases, and the grain weight entering discharging tube 17 increases；When needs reduce flow rate, small front apron 21 is internal mobile to collection kind device along the axial level of outer groove-wheel 19, and 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 inlet air and send pipe charging aperture 25.Wind-force at feed injector 26, by the seed at charging aperture 25, upwards blows along straight tube, and the process that seed outwards blows is through pleated tube 24, and seed mixing is more uniform；Pleated tube diameter little 5mm than straight tube diameter, can play the effect of supercharging, and the seed speed of service is accelerated；Mixing and seed that movement velocity is accelerated being through bend pipe, reach nozzle 23, nozzle 23 uses the flat-shaped sector structure of uiform section area gradual change type, reaches to sow seeds uniformly and increases the purpose broadcasting sowing fabric width.
Tractor dynamic power is passed to blower fan by belt driver by this seed broadcaster, solving that wind spraying aid type sead feeder weight is big, high in cost of production problem, outer groove-wheel, on the premise of meeting Seeding Uniformity, increases outer groove-wheel diameter, reduce seed damage ratio, improve operating efficiency.The innovation of the present invention, is to overcome the restriction of tradition paddy machinery seeding method, uses seed broadcaster to carry out the mechanical planting of paddy rice.Use seed broadcaster to carry out operation, improve operating efficiency, and can sow uniformly, have good application market.
