Embodiment of the present utility model is as follows:

Embodiment 1: referring to Fig. 1～shown in Figure 5, by only beam square steel be welded with the last lower suspension arm that is connected with tractor and form frame 2, three monomers of finishing said function of assembling on the frame 2, in each monomer, breaking plough 7 is bolted on the frame 2 by breaking tool rest 18 and " U " type, plough 7 is on frame 2, but both move left and right can move up and down again and regulate; Support 4 one ends are fixed on frame 2, and plough frame 5 one ends are hinged in support 4 bottom holes.Pull bar 12 upper ends are assemblied on support 4 rear tab and can slide up and down, and pull bar 12 lower ends are hinged on the plough frame 5.Fixedly fertilizer can 1 and seeding unit 15 respectively before and after on support 4 are fixed with seeding box 16 on seeding unit 15 tops.But row-planting opener 9 and the press wheel 11 and the drag sealer 10 of fixing up-down adjustment on plough frame 5, like this, breaking plough 7, row-planting opener 9, press wheel 11 and drag sealer 10 are sequentially arranged on the same drilling row straight line from front to back.In the fertilizer can 1, broach shell 31 " L " type that is welded with that stirs on the last axle 24 stirs cutter, and integral body is stirred cutter line running in the shape of a spiral, unclamps the jackscrew that stirs on broach shell 31 and the defertilizing wheel 25 respectively, can move on last

lower shaft

24 and 23, regulates the fertilizer line-spacing.Fixing defertilizing wheel 25 on the lower shaft 23,

lower shaft

24 and 23 fixing driven

sprocket

27 and 26 respectively on middle monomer one side, the fertilizer-supplying port of fertilizer can 1 bottom communicates with plough 7 lower ends by carrier pipe 6.Head sprocket 19 on the axle 20 connects driven

pulley

27 and 26 by chain 3, and another head sprocket 19 is by driven sprocket 28 fixing on chain 3 connecting bushings 22.Seeding unit 15 tops connect seeding box 16, and the below connects seeding hopper 13, and funnel 13 lower end correspondences are fixed on the row-planting opener 9 on the plough frame 5; In the seeding unit 15, fixing getting in kind of the wheel 45 in the rotating shaft has three several nest eyes of row on its external diameter periphery, and nest intraocular assembling caging bolt 47 and stage clip 46 by adjusting bolt 47 up and down, are controlled the seeding quantity that the nest intraocular is stored seed.On middle monomer, pass the rotating shaft two ends connecting axial sleeve 22 of seeding unit 15, wherein a side shaft puts fixedly driven sprocket 28, link by chain 3 with drive sprocket 19, axle sleeve 22 links with shaft coupling extension bar 14, shaft coupling extension bar 14 is connected to form by extension bar 29 and universal joint 30, wherein regulates sowing distance between the plough 9 with the extension bar 29 of changing different length.Pull bar 12 lower ends are hinged on the plough frame 5, and support 4 rear tab are passed through in the upper end, and can slide up and down.Plough frame 5 rear portions assembling press wheel 11 and " V " type drag sealer 10 of pulling.Above-mentioned said three monomers, the adjustment of horizontal spacing realizes by the both sides monomer.

Operation principle of the present utility model is: adopt the tractor with small four wheels of 4～11 watts of power to connect in rearmounted 3 integral modes, at first adjust the height of breaking plough 7 and row-planting opener 9 and the spacing between three monomers according to different fertilizer, seed, field, plough 7 is regulated in 80～120 millimeters of below grounds, plough 9 is regulated in 30～60 millimeters of below grounds, and line-spacing is regulated in 450～700 millimeters.When tractor and the utility model in running order down, land wheel 8 is with the preceding of tractor and then rotation, thereby two sprocket wheels 19 on the axle 20 are rotated, drive driven

pulley

27,26 and 28 work through chain 3, go up in the fertilizer can 1 in the

lower shaft

24 and 23 stir broach shell 31 and defertilizing wheel 25 rotates, make fertilizer continually ground warp carrier pipe 6, plough 7 put in the trench because the effect of 7 liang of wing plates 44 of plough covers on the fertilizer so its two side portions soil falls after rise in ditch through breach.The seed of seeding box 16 is through seeding unit 15, getting under kind of the rotation of wheel 45, the seed discharge of some is fallen into the native ditch that row-planting opener 9 is left, work in succession through press wheel 11 and drag sealer 10, finish whole a series of breaking trench digging, deep placement base fertilizer, smart amount or semi-accuracy seeding, suppression and earthing function at last.

Embodiment 2: referring to shown in Figure 3, and fertilizer part-structure difference only, all the other structures are identical.On the fertilizer bearing 34, driven sprocket 26 cooperates with tooth embedding form with combined cover 33 in the axle 38, and combined cover 33 is fixed on the axle 38 by jackscrew 40, all is equipped with pivot pin 35, clip 39, defertilizing wheel 32 and feed cutoff 37 on the axle 38 that passes through in each defertilizing box 36.Fertilizer line-spacing between its three monomers is to adjust like this, middle monomer is motionless, pivot pin in the monomer of the left and right sides 35 is transferred to, unclamp clip 39, whole fertilizer parts move on axle 38, determine after the line-spacing, there are several through holes on both sides on axle 38, plug pivot pin 35 in corresponding hole, fixing hoop 39 is promptly finished the line-spacing work of adjusting.Its operation principle is such, and driven pulley 26 drives axle 38 and rotates, and defertilizing wheel 32 is rotation work thereupon, make box 36 internal mobilities preferably fertilizer discharge with certain flow, fall in the ditch.

The utility model has the advantages that:

1,---------smart amount seeding---suppression---earthing operation, the production efficiency height makes per mu yield increase by 15～20%, operation steady quality, but and no-tillage seeding to earthing to dispensing base fertilizer once to finish the breaking trench digging.

2, owing to adopt the spiral stirring blade fertilizer mechanism, the powdered fertilizer of energy discharge flow poor performance, for example ammonium bicarbonate fertilizer.

3, owing to land wheel is being sowed in the width, so on the boundary of a piece of land and the ridge place also can effectively work, land utilization ratio is increased, connect because a pair of land wheel 8 and axle 20 adopt respectively flat key, so in a single day a land wheel 8 unsettled in operation, also do not affect the normal operation of another land wheel 8 and complete machine.

4, owing to adopt the single-beam monomer structure, line-spacing is easy to adjust, and adjusting range is big, is controlled in 450～700 millimeters, and deep fertilizer spraying is on distance ground in 80～120 millimeters, Sowing is on distance ground in 30～60 millimeters, the crop seed such as adopts so be suitable for China's wide geographic area precision drilling corn, beans, lint cottonseed, vegetables.

5, change sprocket wheel and can change fertilizer, seeding gearratio, need not more exchange kind of a wheel 45 for, but just precision drilling.

6, no-tillage speed of action is: the irrigated land is 1.34～1.83 meter per seconds, is to the arplain 1.83～2.16 meter per seconds. Production efficiency be 0.18～0.40 public affairs incline/hour.
