Abstract
This utility model relates to agricultural machinery technology field, title is movable cutter body rotary tillage shaft assembly, including the multiple cutter hubs installed on rotary tillage shaft and rotary tillage shaft, having the mounting seat of cutter hub on described rotary tillage shaft, described cutter hub has multiple installation screw, and near rotary tillage shaft is the first screw, remaining is the second screw, it is characterized in that: described second screw is the notch hole of circular arc, the length of notch has thickening position to the axis around rotary tillage shaft, described cutter hub at groove aperture periphery.Such cutter hub rotary tillage shaft assembly has earth bonding on cutter head and easily comes off, the more preferable advantage of using effect；Described cutter hub has thickening position at groove aperture periphery, also has the long-lived advantage of cutter hub.
Description
Technical field
This utility model relates to agricultural machinery technology field, concretely relates to rotary tillage shaft assembly.
Background technology
Rotary cultivator has rotary tillage shaft assembly, and rotary tillage shaft assembly includes the multiple cutter hubs installed on rotary tillage shaft and rotary tillage shaft；Existing
Having in technology, cutter hub is fixedly mounted on rotary tillage shaft, i.e. cutter hub and rotary tillage shaft becomes and be rigidly connected, so, in use
Some earth bonding on cutter hub, with regard to difficult drop-off, affect farming effect.
Summary of the invention
The purpose of this utility model is aiming at disadvantages mentioned above, it is provided that earth bonding on a kind of cutter head easily comes off, and makes
With effect more preferable cutter hub rotary tillage shaft assembly movable cutter body rotary tillage shaft assembly.
Technical solution adopted in the utility model is: movable cutter body rotary tillage shaft assembly, including on rotary tillage shaft and rotary tillage shaft
The multiple cutter hubs installed, described rotary tillage shaft has the mounting seat of cutter hub, and described cutter hub has multiple installation screw, near rotary tillage
Axle is the first screw, and remaining is the second screw, it is characterized in that: described second screw is the notch hole of circular arc, notch
Long to the axis around rotary tillage shaft.
Saying further, described cutter hub has thickening position at groove aperture periphery.
The beneficial effects of the utility model are: such cutter hub rotary tillage shaft assembly has earth bonding on cutter head and easily takes off
Fall, the more preferable advantage of using effect；Described cutter hub has thickening position at groove aperture periphery, also has cutter hub long-lived excellent
Point.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation on the right side at A in Fig. 1.
Wherein: 1, rotary tillage shaft 2, cutter hub 3, mounting seat the 4, first screw the 5, second screw 6, thickening position.
Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, movable cutter body rotary tillage shaft assembly, including the multiple cutter hubs 2 installed on rotary tillage shaft 1 and rotary tillage shaft,
Having the mounting seat 3 of cutter hub on described rotary tillage shaft, described cutter hub has multiple installation screw, and near rotary tillage shaft is the first screw
4, remaining is the second screw 5, it is characterized in that: described second screw is the notch hole of circular arc, and the length of notch is to around rotary tillage
The axis of axle.
So cutter hub just has certain activity connect with rotary tillage shaft, in use will get rid of and be bonded on cutter hub
Earth, has advantage of the present utility model.
Saying further, described cutter hub has thickening position 6 at groove aperture periphery, so reduces the mill around the second hole
Damage.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model be not limited to this,
Any those skilled in the art is in field of the present utility model, and change or the modification made all are contained of the present utility model
In the scope of the claims.
