Embodiment:

The utility model comprises the fertile shovel 12 of deep placement, plough 9, seeding unit 8, fertile case 4, plants case 7,

A, be installed with fertilising cover 14 at front-axle beam 1, fertilising shovel bar 13 is inserted in the fertilising cover 14, and fertilising shovel bar 13 lower ends are equipped with the fertile shovel 12 of deep placement;

B, the axle that is installed in hydraulic motor 2 on the body are connected by fertilising chain 15 with the fertilising roller 16 of fertile case 4 fertilizer outlets, and fertile case 4 shovels 12 with deep placement fertilizer and is communicated with by fertilizer delivering pipe;

Be installed with the back rest 3 on c, the front-axle beam 1, parallel four-bar feeler mechanism 5 is installed on the back rest 3, and four bar connecting portions of parallel four-bar feeler mechanism 5 all are that axle connects;

D, plough cover 18 are fixedly mounted on the parallel four-bar feeler mechanism 5, and the bar of plough 9 is plugged in the plough cover 18;

Land axle 17 and seeding unit 8 on the land wheel 6 are installed on e, the plough cover 18, and land axle 17 is connected with feed shaft on the seeding unit 8 by chain, and kind case 7 is installed in seeding unit 8 upper ends;

Be installed with girder 19 on f, the seeding unit 8, girder 19 is equipped with

support bar

20, and 10 on earthing wheel is connected on the support bar 20;

The front end of g, girder 19 is connected with fork 21 by axle, axle is connected with packer 11 on the fork 21, on girder 19, be installed with oblique fulcrum bar 22, one end of pole 23 is inserted in the front aperture of oblique fulcrum bar 22, pole 23 other ends are fixed on the fork 21, are with spring on the pole 23 between oblique fulcrum bar 22 and the fork 21.

1, single group parallel four-bar profiling: the single group of each of sower is hinged on the frame, can singly organize profiling, and other soil-engaging component such as covering device on single group, press wheels etc. can also carry out independent profiling with respect to single group.During operation, each Dan Zuke carries out profiling up and down separately according to different landform.Its profiling is more accurate, and effect is better.

2, the core share type plough is simple in structure, and penetration performance is better, and bottom of trench is smooth, and is less demanding to seedbed preparation, is adapted to the ridge culture wide cut sowing of China's the Northeast's corn.The design narrows down plough, has reduced the spring amount of breaking ground that working resistance reduces again, has played good soil moisture conservation effect.
