Embodiment
Describe the utility model in detail below with reference to the accompanying drawings.
A kind of Blades for rotary cultivator, as shown in Fig. 1 ~ Fig. 4, the blade is steel blade, including plane blade and curved
Two kinds of fold-type blade.The blade includes installation portion 1 and underlying blade 2 above；The top of the installation portion 1
For globoidal structure, the mounting hole 11 of circle is offered on installation portion 1, blade is fixed on tool rest by mounting hole 11；It is described
Blade 2 is rectangular configuration, and alloy wear-resisting layer 21 is also set up on the working face of blade 2；The thickness of the alloy wear-resisting layer 21 is not
Less than 5mm, its length is 60mm.
Be in certain bending angle between the installation portion 1 and blade 2 of the bending type blade, the angle of bending angle for 150 ° ~
180°.In the embodiment shown in Fig. 3, Fig. 4, the angle of bending angle is 160 °.
The lower section of the mounting hole 1 is further opened with 12 used in blade process, the processing hole 12 and mounting hole
11 circle center line connecting is vertically with blade base, and the diameter for processing hole 12 is less than the diameter of mounting hole 11.
The blade is processed by the thick 40Cr steel plate puncheds of 5mm, and alloy wear-resisting layer is that powder metallurgy is used into laser
Cladding is formed, and intensity is high, and wearability is good, and the soil for going for various soil properties is cultivated.
The specific size of blade can be adjusted according to the model and specifically used requirement of rotary cultivator.In Fig. 1 ~ Fig. 4 institutes
In the razor blade stock shown, blade thickness is 5.5mm, and blade width is 51mm, and the length of installation portion is 100mm, the length of blade
For 60mm, a diameter of 21mm of mounting hole, a diameter of 13mm in hole is processed.
The alloy wear-resisting layer includes the following component in terms of mass fraction：Sodium 0.5% ~ 2.0%, magnesium 1.0% ~ 2.0%, silicon
