Receptacle 14 and seed-box 21 quantity of this valve-type multifunctional precision seeder are equal；The feed opening 17 of receptacle 14 and seed-box 21 go out to be respectively arranged with on kind of mouth 24 air inlet 31, the feed opening 17 of receptacle 14 is connected by bronchus 32 by air inlet 31 between kind of mouth 24 with going out of seed-box 21；Equipped with blower fan 34 on the rotary tillage support 1 of decelerator 2 rear end of rotary cultivator attachment；Bronchus 32 is connected with blower fan 34 by air main 33.
The termination of the transmission long axis 11 of this valve-type multifunctional precision seeder, receptacle major axis 15 and Seeding box major axis 23 is separately installed with drive sprocket 35；Precision seeding machine is connected with receptacle major axis 15 and the transmission long axis 11 of fertilizer applicator by drive sprocket 35 and driving-chain 6 respectively by Seeding box major axis 23.
By installing rack and regulation spring 38, coverer 36 and pack roller 37 are installed in the ferti-seeding frame 10 of power land wheel 12 front end；Equipped with sprocket transmission 39 on power land wheel 12.
During the work of this seeder, first fertilizer and seed are respectively put in receptacle 14 and seed-box 21, then select the transmission range of suitable application rate according to agriculture requirement by sprocket transmission 39, then regulate the degree of depth of rotary tillage process and seeding operation and i.e. accuse preparation and complete.In work process, this seeder moves ahead under the traction of traction apparatus (tractor), and is driven the rotary blade 4 of rotary cultivator attachment to rotate by the power of traction apparatus, completes the rotary tillage to agricultural land soil.
This seeder is while moving ahead, and the power land wheel 12 of fertilizing and seeding apparatus is along with the traction rolls forward of tractor, thus drives transmission long axis 11 to rotate, and then drives receptacle major axis 15 and Seeding box major axis 23 synchronous axial system.Meanwhile, dislocation shape is arranged fertilising ditching plow 16 and seed ditching plow 22 plow dressing furrow and seed furrow respectively in agricultural land soil.
During receptacle major axis 15 and Seeding box major axis 23 synchronous axial system.Corresponding dispenser and seed-taking device is oppressed respectively by cam 19；Owing to dispenser and seed-taking device are to be movably arranged on respectively in receptacle 14 and seed-box 21 by spring 20 and mounting rod 28, under cam 19 contention effect, the feeding bar 25 of dispenser and seed-taking device moves up and down under the drive of pipe 26 is installed in regulation respectively in receptacle 14 and seed-box 21.
During feeding bar 25 moves up and down respectively in receptacle 14 and seed-box 21；Kind of mouth 24 is gone out respectively in " b " shape due to the feed opening 17 of receptacle 14 and seed-box 21.I.e. feed opening 17 and to go out the upper end of kind of mouth 24 be osculum end, feed opening 17 and the lower end going out kind of mouth 24 are big opening end, when the feeding recess 29 on feeding bar 25 goes upward in receptacle 14 or seed-box 21 with feeding bar 25, granular fertilizers or seed in receptacle 14 or seed-box 21 enter in feeding recess 29 naturally, due to bottom and the feed opening 17 of feeding bar 25 or go out the osculum end of kind of mouth 24 and fit tightly, and feeding bar 25 can not be deviate from during moving up and down in osculum end；Therefore, during feeding bar 25 is descending, seed or fertilizer beyond feeding recess 29 are still blocked in receptacle 14 or seed-box 21.When the feeding recess 29 equipped with fertilizer or seed comes downwards to feed opening 17 with feeding bar 25 or goes out the big opening end of kind of mouth 24, the air inlet 30 of feeding recess 29 side just coincide with air inlet 31, under the effect of blower fan 34, fertilizer or seed in feeding recess 29 are blown, thus by entering to ditching plow 16 communicating pipe 18 or in dressing furrow that seed ditching plow 22 plows in agricultural land soil or seed furrow.Subsequently, dressing furrow and seed furrow both sides soil are closed up to ditch by coverer 36, complete burying of fertilizer and seed, and by pack roller 37, chesson are densified to certain tightness, thus complete the whole operation process of rotary tillage, fertilising and precision drilling.In the operation process of this seeder, the gutter colter 13 arranged by ferti-seeding frame 10 both sides can be simultaneously to making industrial belt both sides and complete the excavation in gutter, the draining being beneficial in later stage process of crop growth.
Multiple feeding recesses 29 that shape is arranged it are spaced on the feeding bar 25 of this seeder；Its volume size is different, owing to the stroke run up and down of feeding bar 25 is fixed, therefore in practical work process, by telescopic adjustment feeding bar 25, the feeding recess 29 that optional use is different；Therefore the planting seed of Different Crop it is suitable for；And determine to take kind of (2 or 3), take fertile amount, it is achieved in the purpose of accurate fertilizing sowing.This seeder simple in construction, modern design, solve existing precision drilling and rely primarily on and manually carry out program request, there are the problems such as efficiency is low, labor intensity is big, operation quality is poor.To improving crop yield, reduce seed consumption, reduce planting cost and there is positive dissemination.
