Abstract
The invention relates to the technical field of agricultural machines, in particular to a movable cutter body and rotary tillage shaft assembly. The movable cutter body and rotary tillage shaft assembly comprises a rotary tillage shaft and a plurality of cutter bodies installed on the rotary tillage shaft, wherein installation seats for the cutter bodies are arranged on the rotary tillage shaft, the cutter bodies are provided with a plurality of installation bolt holes, the installation bolt hole close to the rotary tillage shaft is a first bolt hole and other installation bolt holes are second bolt hole. The movable cutter body and rotary tillage shaft assembly is characterized in that the second bolt holes are arc-shaped slot holes, length directions of slots surround an axis of the rotary tillage shaft, and the cutter bodies are provided with thickening parts around the slot holes. The movable cutter body and rotary tillage shaft assembly has the advantages that the mud stuck to cutters heads falls off easily and the use effect is better; since the cutter bodies are provided with the thickening parts around the slot holes, the movable cutter body and rotary tillage shaft assembly further has the advantage of high cutter body durability.
Description
Technical field
The present invention relates to agricultural machinery technology field, concretely relate 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；In prior art, cutter hub is fixedly mounted on rotary tillage shaft, and namely cutter hub and rotary tillage shaft become and be rigidly connected, and so, some in use bonding on cutter hub earth, with regard to difficult drop-off, affect farming effect.
Summary of the invention
The purpose of the present invention is aiming at disadvantages mentioned above, it is provided that earth bonding on a kind of cutter head easily comes off, result of use better cutter hub rotary tillage shaft assembly movable cutter body rotary tillage shaft assembly.
The technical solution used in the present invention is: movable cutter body rotary tillage shaft assembly, including the multiple cutter hubs installed on rotary tillage shaft and rotary tillage shaft, described rotary tillage shaft has the mounting seat of cutter hub, described cutter hub has multiple installation screw, 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, and the length of notch is to the axis around rotary tillage shaft.
Saying further, described cutter hub has thickening position at groove aperture periphery.
The invention has the beneficial effects as follows: such cutter hub rotary tillage shaft assembly has earth bonding on cutter head and easily comes off, the better advantage of result of use；Described cutter hub has thickening position at groove aperture periphery, also has the long-lived advantage of cutter hub.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation on the right side, A place in Fig. 1.
Wherein: 1, rotary tillage shaft 2, cutter hub 3, mounting seat the 4, first screw the 5, second screw 6, thicken position.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
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, described rotary tillage shaft has the mounting seat 3 of cutter hub, described cutter hub has multiple installation screw, and near rotary tillage shaft is the first screw 4, and remaining is the second screw 5, it is characterized in that: described second screw is the notch hole of circular arc, the length of notch is to the axis around rotary tillage shaft.
Such cutter hub just has certain activity connect with rotary tillage shaft, in use will get rid of the earth being bonded on cutter hub, have advantages of the present invention.
Saying further, described cutter hub has thickening position 6 at groove aperture periphery, so reduces the abrasion around the second hole.
The foregoing is only specific embodiments of the invention, but the architectural feature of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and change or the modification made all are encompassed in the scope of the claims of the present invention.
