The fertilizer can 14 of this valve-type multifunctional precision seeder is equal with seed-box 21 quantity; Feed opening 17 and the going out on kind of mouth 24 of seed-box 21 of fertilizer can 14 are respectively arranged with air inlet 31, and the feed opening 17 of fertilizer can 14 is communicated with by bronchi 32 by air inlet 31 with going out between kind of mouth 24 of seed-box 21; The rotary tillage support 1 of decelerator 2 rear end of rotary cultivator attachment is equipped with blower fan 34; Bronchi 32 is communicated with blower fan 34 by air main 33.
The termination of the transmission long axis 11 of this valve-type multifunctional precision seeder, fertilizer can major axis 15 and Seeding box major axis 23 is separately installed with drive sprocket 35; Precision quantitative seed drill is connected with the fertilizer can major axis 15 of fertilizer applicator and transmission long axis 11 by drive sprocket 35 and driving-chain 6 respectively by Seeding box major axis 23.
The ferti-seeding frame 10 of power land wheel 12 front end is provided with covering device 36 and pack roller 37 by installing rack and regulating spring 38; Sprocket transmission 39 power land wheel 12 is equipped with.
During the work of this sower, first fertilizer and seed are put into fertilizer can 14 and seed-box 21 respectively, then selected the speed change gear of suitable seeding quantity by sprocket transmission 39 according to agriculture requirement, namely the degree of depth then regulating rotary tillage process and seeding operation is accused preparation and is completed.In the course of work, this sower moves ahead under the traction of draw-gear (tractor), and drives the rotary blade 4 of rotary cultivator attachment to rotate by the power of draw-gear, completes the rotary tillage to agricultural land soil.
This sower is while moving ahead, and the power land wheel 12 of fertilizing and seeding apparatus along with the traction rolls forward of tractor, thus drives transmission long axis 11 to rotate, and then drives fertilizer can major axis 15 and Seeding box major axis 23 synchronous axial system.Meanwhile, the fertilising furrow plough 16 that the shape that misplaces is arranged and seed furrow plough 22 plow dressing furrow and seed furrow respectively in agricultural land soil.
In the process of fertilizer can major axis 15 and Seeding box major axis 23 synchronous axial system.The dispenser corresponding with it and seed-taking device is oppressed respectively by cam 19; Because dispenser and seed-taking device are movably arranged in fertilizer can 14 and seed-box 21 respectively 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 respectively under the drive regulating mounting pipe 26 in fertilizer can 14 and seed-box 21.
In the process that feeding bar 25 moves up and down respectively in fertilizer can 14 and seed-box 21; Because the feed opening 17 of fertilizer can 14 and kind of the mouth 24 that goes out of seed-box 21 are " b " shape respectively.Namely feed opening 17 and the upper end that goes out kind of mouth 24 are 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 fertilizer can 14 or seed-box 21 with feeding bar 25, granular fertilizers in fertilizer can 14 or seed-box 21 or seed enter in feeding recess 29 naturally, because the bottom of feeding bar 25 and feed opening 17 or the osculum end that goes out kind of mouth 24 fit tightly, and feeding bar 25 can not be deviate from the process moved up and down in osculum end; Therefore, in the descending process of feeding bar 25, the seed beyond feeding recess 29 or fertilizer are still blocked in fertilizer can 14 or seed-box 21.When the feeding recess 29 that fertilizer or seed be housed comes downwards to feed opening 17 with feeding bar 25 or goes out the big opening end of kind of mouth 24, the air admission hole 30 of feeding recess 29 side just in time coincide with air inlet 31, under the effect of blower fan 34, fertilizer in feeding recess 29 or seed are blown, thus by entering to communicating pipe 18 in dressing furrow or seed furrow that furrow plough 16 or seed furrow plough 22 plow in agricultural land soil.Subsequently, dressing furrow and seed furrow both sides soil close up in ditch by covering device 36, complete burying of fertilizer and seed, and by pack roller 37, chesson are densified to certain tightness, complete the whole operation process of rotary tillage, fertilising and precision drilling thus.In the operation process of this sower, the drain ditch colter 13 arranged by ferti-seeding frame 10 both sides simultaneously to the excavation doing industrial belt both sides and complete drain ditch, can be beneficial to the draining in later stage process of crop growth.
Multiple feeding recesses 29 that on the feeding bar 25 of this sower, interval shape is arranged; Its volume size is different, because the stroke run up and down of feeding bar 25 is fixed, therefore in practical work process, by telescopic adjustment feeding bar 25, and can the different feeding recess 29 of choice for use; Therefore the planting seed of Different Crop can be adapted to; And decision is got kind of (2 or 3), is got fertile amount, realizes the object of accurate fertilizing sowing thus.This sower structure is simple, novel in design, solves existing precision drilling and mainly relies on and manually carry out program request, there are the problems such as efficiency is low, labour intensity is large, operation quality is poor.To raising crop yield, reduce seed consumption, reduce planting cost and there is positive dissemination.
