When face fluctuating or hard objects, copying spring can be compressed, plough is rotated around axis pin to be lifted, behind the region, by bullet
Spring pretightning force return；The subsequent earthing of casing mechanism later, passively rotation backfills both sides soil to double-arc spline, rises and falls when encountering road surface
Or when hard objects, tension spring 10 can be stretched, complete profiling, back roll then beat bunch planting kind, beat cave seeding belt and apply fertilizer band not
It overlaps, seed is prevented to be seeded on fertilizer, influence germination growth；Cave needle of beating on roller relies on negative-pressure adsorption in plants case
Seed beats the isolation board protrusion that cave needle enters in gas chamber, air pressure, seed can be blocked to fall when playing cave needle and being in bottom
Under, complete sowing.
It is fixedly connected with U-shaped card 8 between roller back rest frame 14 and rack 9, roller back rest frame 14 is connected on roller respectively
Beam 15 is connected with tie-beam under roller 16 by axis pin, and two bar of the other end is connect with roller connection sheet 17 and roller connecting seat 18,
It forms a parallelogram lindage and provides profile modeling function for roller, roller connecting seat 18, drum cover 19 and roller 23 are connected to one
It rises, drum cover 19 is that the gas chamber 36 of roller 23 provides sealing, ensures that gas chamber 36 will not gas leakage；Roller connecting seat 18 and drum cover 19
On in the lower left corner be provided with stomata, tracheae is inserted into wherein being that gas chamber 36 provides air pressure, it is also desirable to ensure leakproofness；Drum cover 19
On right lower quadrant have protrusion be air chamber cover isolation board 35, gas chamber 36 can be isolated and beat the gas between the hollow hole in cave needle 21
Pressure, to play cave needle 21 in minimum point planting；18 another side of roller connecting seat is connected with plants case connecting rod 22, plants case connecting rod 22,
It suppresses connecting rod 24 and suppression bar 26 constitutes a cam mechanism, suppression bar 26 is a tube-in-tube structure, Neng Goushen
Contracting, facilitates profiling.It is distributed with 84 in 23 three rows of outside point of roller and plays cave needle 21, has suction kind slot 30 on the top for playing cave needle 21,
Facilitate receiving seed；
Suppression connecting rod 24 and the lower end for suppressing bar 26 are connected to above the axis of press wheel 27, and press wheel 27 can complete three
The suppression work of row sowing；At the rear of roller 23, cooperation is equipped with plants case 25, three slots is provided in plants case, three rows is coordinated to beat cave
Needle 21 has fine and close bristle in per pass slot, prevents seed from sliding.
It is last it is to be noted that：Above example is only to illustrate the technical solution of the utility model, rather than limits it
System.Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should manage
Solution：Its still can with technical scheme described in the above embodiments is modified, or to which part technical characteristic into
