Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~4, in the utility model embodiment, a kind of disc harrow with protection mechanism and fertilizing functions, bag
Include：Hitch frame 1, frame 7, some blades 2, protection mechanism and fertilizing mechanism 8, the blade 2, which is fixed on, is installed on the bottom of frame 7
Rotating shaft on, the hitch frame 1 is weldingly fixed on one end of frame 7；The protection mechanism includes：Expansion link 5, screw rod 6 and rolling
Wheel 3, the expansion link 5 is rotatably installed in frame 7, and the roller 3 is arranged on the bottom of expansion link 5, expansion link 5 and roller 3
Two groups are shared, and symmetrically, and the top of one of expansion link 5 sets through hole, another top of expansion link 5 is threaded hole,
The screw rod 6 is arranged in the through hole and screwed hole of two expansion links 5, and protection mechanism shares two groups, is separately positioned on rotating shaft 10
Both sides, rotate threaded rod 6, two expansion links 5 is mutually rotated, two rollers 3 are close to each other, when roller 3 contacts with ground
Afterwards, just support 7 is supported, and blade 2 departs from ground, and so just blade 2 is not caused to utilize roller 3 in the case of damage
Move；The fertilizing mechanism 8 is fixed in frame 7, and fertilizing mechanism 8 includes charging hopper 82 and sub-material chamber 84, the charging
Bucket 82 and the top of sub-material chamber 84 are connected by charging aperture 83, and the sub-material chamber 84 is cylinder barrel shaped, and the installation of its axial location drives
Axle, some catch 85 in circular arc, the width size of catch 85 and the width phase of charging aperture 83 are evenly distributed in drive shaft
When, and gap is left between adjacent two catch 85, when catch 85 is moved to 83 lower section of charging aperture, charging aperture 83 is blocked, kept off
After piece 85 is removed, fertilizer is fallen into from charging aperture 83 in sub-material chamber 84, and such charging aperture 83 is discontinuously opened, and realizes that fertilizer is interrupted
Property blanking, so with the processing such as follow-up land presser suppression are closed, fertilizer can be made to be mixed with soil, guarantee discharge quantity " it is even and
It is infertile ", it can reduce fertilizer compared to the mode continuously broadcasted sowing and waste.
The bottom of sub-material chamber 84 sets discharge bucket 86, the feed opening of the bottom of the discharge bucket 86 connection rectangular cross-section
87。
The feed opening 87, which is connected to, is inclined at the rear of frame 7（By disc harrow work direction of advance）Stock guide 81
On, length direction of such fertilizer along feed opening 87 flows into stock guide 81, can more uniformly sow to ground.
Driving wheel 4, the driving wheel 4 and driving axis connection is fixedly mounted in the end of rotating shaft 10, is rotated in blade 2 same
When, drive shaft turns are driven, realize blanking simultaneously.
Eccentric block 9 is fixedly mounted in the middle part of the rotating shaft 10, and during axis of rotation, eccentric block 9 produces the moment of inertia, makes
Disc harrow up-down vibration, one can increase blade 2 dig, the dynamics of disconnected stubble, two fertilizer can be prevented in charging aperture vibrating or
Blocked in feed opening.
Caging bolt 61 is set on the screw rod 6, prevents screw rod 6 from being come off from screwed hole.
