Lifting arm is connected with spring pull bar 25, and two ends link to each other with girder 22 with lifting arm rotating shaft 3 respectively. Seed-fertilizer box 11 is connected with seed manure pipe 12, and seed manure pipe 12 1 ends are connected with seeder, (seeder is not shown in FIG.). Hanger bracket 21 is connected with tractor rear, and link 4 is connected with tractor rear axle 5, rises and falls and removes 9, and connecting rod 7, locating rack 6 link together and jointly be fixed on the tractor, adjust the lifting of whole device. Seed-fertilizer box 11 is fixed on the rear fender of tractor, and chain 10 is driven by tractor rear wheel and drives seed manure Seed manure broadcast device in the case 11. Weeding tooth 23 is fixed on the raking wheel 24. Each part assembly relation is seen accompanying drawing 1, accompanying drawing 2.

The utility model operation principle is as follows:

＜a 〉: cultivated land function (seeing accompanying drawing 1, accompanying drawing 2): take off seed manure case 11, chain 10, seed manure pipe 12, raking wheel pull bar 18 becomes primary tillage equipment behind the raking wheel 24.Hanger bracket 21 is fixed on tractor rear, and link 4 is fixed on the tractor rear axle.Angle modulation leading screw 15 1 ends and tractor-drawn frame join.Three ploughshares can be installed on the girder 22.Once plough and do two ridges, adjust the size of plough shovel penetrating angle by angle modulation handwheel 2 and angle modulation line thick stick 15.Remove 9 by rising and falling and rise and fall and adjust connecting rod 8 and adjust crank 13 and adjust tilling depth, and whole plough body can be lifted (first-class as ground) when needed.Remove 9 during the end of job by rising and falling and rise and fall to adjust connecting rod 8 and adjust crank 13 whole plough body is erected the afterbody that is secured in car, hang up trailer, and will not pull down by whole plough, shovel pylon 17 can be on girder 22 traversing change row spacing; Earth separation plate 19 can change the ridge type.Change that plough shovel 20 can be realized the level land, function such as plough; Spring 14 plays buffering, can protect plow frame.

＜b 〉: sowing function (seeing accompanying drawing 1, accompanying drawing 2): will plant with nutriment in a fertilizer and not put into seed manure case 11, seeder is discharged seed and fertilizer by chain 10 transmissions by the seed manure pipe; To plough shovel 20 and change furrower into, raking wheel 24 changes press wheel into, and earth separation plate changes soil covering implement into, can realize seeding operation.Seed manure case 11 is installed on the tractor rear wing grillage.

＜c 〉: weeding function (seeing accompanying drawing 1, accompanying drawing 2): take off chain 10, seed manure case 11, seed manure pipe 12 will be ploughed shovel 20 and be changed the weeding plate into, pull four raking wheels 24 behind the girder, can realize weeding work.
