The course of work of the present invention is as follows：
At work, hydraulic cylinder is strutted for cereal precision drill, so that left seed-box 20, intermediate seed-box 19 with
And it is in alignment between right seed-box 11, left seed-box 20, intermediate seed-box 19 and right seed-box thus may be used
11 are carried out at the same time seeding operation, and the seed addition in left seed-box 20, intermediate seed-box 19 and right seed-box 11 shuts seed-box
Chamber door starts transmission mechanism and carries out operation.
Seed is entered from left seed-box 20, intermediate seed-box 19 and right seed-box 11 in seeder unit shell 1, is sowed
Wheel 2 rotates under the drive of motor, and seed drops into the cavities of seeding wheel 2, and the hairbrush 3 by being contacted with seeding wheel 2 will
The seed on 2 surface of seeding wheel brushes off so that 2 surface of seeding wheel does not have seed residual, while seed is all distributed in cavities.Sowing
Wheel 2 reaches after hairbrush 3 at seed-pretecter 4, and the shell of seeding wheel 2 is close to by the belt 42 of seed-pretecter 4, thus by the portion
The cavities divided is blocked, and when seeding wheel 2 rotates, seed will not be dropped out from cavities, until cavities is left on seeding wheel 2
When the belt of seed-pretecter 4, seed can be fallen from cavities, and the process of sowing can be realized in this way.
When the capacity for needing cavities on adjusting seeding wheel, that is, the depth for adjusting cavities is passed through by unclamping lock-screw
Rotation hand wheel 7 so that shaft is moved in left and right directions, to drive core pulling wheel 25 to move left and right so that sliding block 22 and pumping
Opposite sliding is formed between core wheel 25, since sprue 26 is arranged in through-hole 21, so sprue 26 can be slided in sliding block 22
When, it realizes and moves up and down in through-hole 21, so as to adjust the depth of cavities, reached the mesh for adjusting cavities capacity
, it regulates and then locks lock-screw 8 and spindle keyway 28.
After seeding operation, hydraulic cylinder is shunk, and left seed-box 20 and right seed-box 11 is pulled upwardly, thus
Hill-drop drill can be folded up, convenient for walking on road.
The present invention is connect by the way that left and right seed-box and intermediate seed-box is arranged by cylinders, can be by left and right kind
Sub- case is folded up, and can ensure locomotive normally travel on track, safe, while left and right seed-box being put down
Wide cut operation is carried out, sowing is efficient；The feed mechanism for seed of the hill-drop drill is by being arranged handwheel and core pulling wheel construction, and in core pulling wheel
It is upper that sprue is connected by sliding slot, it can realize that sprue moves up and down in the through-hole on sowing shell by adjusting handle, to
The adjusting for realizing the depth of sowing cavities, so as to adjust application rate；By the shell of seeding wheel be arranged to two sections it is split type
Structure, convenient for the installation of core pulling wheel and shaft；Side seed-pretecter is constituted by the way that roll shaft belt is arranged, it can well will be in cavities
Seed be sent to discharge pit from charging place, and the distance of seed-pretecter effect, using effect are good.
The technical means disclosed in the embodiments of the present invention is not limited only to the technological means disclosed in the above embodiment, further include by with
Upper technical characteristic arbitrarily the formed technical solution of combination.
