Abstract
The utility model provides a rotary tillage blade holder which reduces the resistance. The basic structure comprises a blade holder body with a fixing hole of the rotary tillage blade, a bolt jack which is arranged on the blade holder body, and an arc-shaped extension arm which is arranged on the welding end surface of the blade holder body and the rotary tillage blade axle. The utility model is characterized in that a cutting edge is arranged on the blade holder body in the direction of the rotary tillage. Compared with the prior rotary tillage blade holder, the technical proposal adopted by the utility model has the advantages that the cutting edge arranged on the blade holder reduces the forward resistance of the rotary tillage blade, increases the stress intensity of the blade holder, and effectively prolongs the service life of the rotary tillage blade holder.
Description
Technical field
The utility model relates to a kind of rotary tillage tool rest that reduces resistance, belongs to agricultural machinery accessory technical field.
Background technology
The rotary blade of existing rotovator generally adopts and is bolted on the tool rest, tool rest is welded on the connected mode on the rotary ploughing cutter shaft again.The shortcoming of this connected mode is that rotary tillage tool rest and turning cylinder contact-making surface are little, and the rotary tillage tool rest is a rectangle, damages easily under the bigger situation of the on-the-spot resistance of farming.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary tillage tool rest that cutting edge is set, and to reduce the rotary blade resistance, improves service life.
The technical solution of the utility model is achieved in that this rotary tillage tool rest that reduces resistance, its basic structure comprises the tool post that the rotary blade fixing hole is set, screw jack is set on the tool post, the arc adjutage that tool post and rotary ploughing cutter shaft welding end surface are provided with, it is characterized in that: tool post is provided with cutting edge in the rotary tillage direction.
The described rotary tillage tool rest that reduces resistance, described tool post is a Y shape at the cutting edge of rotary tillage direction setting, cutting edge extends to the arc adjutage always.
The described rotary tillage tool rest that reduces resistance, the rotary blade of described tool post inserts end face and is provided with reinforcement.
The technical solution adopted in the utility model is compared with existing rotary tillage tool rest, and its technological progress effect shows: cutting edge is set on the tool rest has reduced the resistance that rotary blade advances, increased the force intensity that is subjected to of tool rest, effectively prolonged the service life of rotary tillage tool rest.

Embodiment
Be a kind of embodiment of the utility model rotary tillage tool rest shown in Fig. 1-4: its basic structure as shown in FIG., this is with to be tool post with novel main innovate point be provided with cutting edge reducing the resistance that rotary blade 7 advances in the rotary tillage direction,
The rotary blade insertion end face that elongation technology scheme of the present utility model also is included in tool post 1 is provided with reinforcement 5, in rotary blade pedestal 1 and rotary ploughing cutter shaft 9 welding end surface arc adjutage 11 is set, and Y shape cutting edge extends on the arc adjutage always.The utility model not only increases the contact-making surface of tool rest and cutter shaft with the intensity of further enhancing tool rest under rotary blade rotation stressing conditions, and the tool rest cutting edge also effectively reduces the service life that resistance has prolonged the rotary tillage tool rest.
Foregoing description only reduces several enforceable technical schemes propositions of rotary tillage tool rest of resistance as the utility model, as the single restrictive condition to its structure itself.
