Description
Technical field
The utility model relates to a kind of agricultural rotovator work Rotary tillage blade.
Background technology
At present, the rotovator that China is agricultural, rotary tillage or stubble-cleaning generally use the curved or right tilling blade sheet in a left side, its thickness is the 3.5-10 millimeter, yet above-mentioned blade is thicker, rolled steel dosage is big, the cost of manufacture height, and resistance is bigger during rotary tillage, power consumption is big, and I am in application Blades for rotary cultivator in 1997, the patent No. be " 97249956.3 " yet, this Blades for rotary cultivator is when work, power consumption is big, intensity difference, and blade is fragile.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, intensity height, the Rotary tillage blade of long service life.
In order to achieve the above object, the technical solution adopted in the utility model is: the polyline shaped knife back is formed by trailing edge and trailing edge in blade body front end position, and blade body back segment position has connecting hole, is provided with the arcuation reinforcement between two connecting holes.
The utility model has the advantages that:
Simple in structure, reasonable in design, easily processing, cost is low, intensity is high, long service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to schematic diagram;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model is that the polyline shaped knife back is formed by trailing edge 2 and trailing edge 3 in blade body 1 front end position, and blade body 1 back segment position has between 4, two connecting holes 4 of connecting hole and is provided with arcuation reinforcement 5.
The thickness of blade body 1 is the 2.0-2.5 millimeter.
Therefore the utility model has improved the strong of Rotary tillage blade owing to be provided with the arcuation reinforcement between two holes Spend, prolonged the service life of Rotary tillage blade, the cost when having reduced rotary tillage process. The utility model The cutter hub consistency of thickness is equivalent to cut the earth with spade, and littler than existing blade work resistance, it is little to consume energy, High efficiency.
