Specific embodiment
Describe the present invention 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
It is 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 that blade process is used, the processing hole 12 and mounting hole
11 circle center line connecting vertically with blade base, process hole 12 diameter less than mounting hole 11 diameter.
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 of rotary cultivator and specifically used requirement.In Fig. 1 ~ Fig. 4 institutes
In the razor blade stock for showing, blade thickness is 5.5mm, and blade width is 51mm, and the length of installation portion is 100mm, the length of blade
It is 60mm, a diameter of 21mm of mounting hole, processes a diameter of 13mm in hole.
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
1.5% ~ 2.5%, tungsten 3% ~ 4%, manganese 1.5% ~ 2.5%, balance of iron；
Preferably comprise：Sodium 1.0% ~ 1.2%, magnesium 1.4% ~ 1.8%, silicon 1.8% ~ 2.0%, tungsten 3.5% ~ 3.8%, manganese 1.7% ~ 2.0%, surplus
It is iron；
Most preferably comprise：Sodium 1.1%, magnesium 1.5%, silicon 1.9%, tungsten 3.6%, manganese 1.9%, balance of iron.
Take the blades of the present invention of two batches production, Mechanics Performance Testing carried out to its knife edge part, labeled as DP-1,
DP-2, at the same take that, structure identical with DP-1 batches be identical but blade of unwelded alloy wear-resisting layer as a comparison, labeled as DB-
1；Take that, structure identical with DP-2 batches be identical but blade of unwelded alloy wear-resisting layer as a comparison, labeled as DB-2.It is described
Mechanics properties testing result is as shown in table 1.
The mechanical experimental results of table 1
The tensile strength in knife-blade portion of the present invention, yield strength, elongation percentage are can be seen that by data in table 1 to be all remarkably higher than
Control group, it was demonstrated that blade of the present invention can bear external force higher without being broken, and local peaks stress can be adjusted when in use
Ability it is strong, can effectively clear up stress, reduce blade and fracture, destruction occur.
The product of blade DP-1, DB-1, DP-2, DB-2 with batch is taken respectively, labeled as DP-1 ', DB-1 ', DP-2 ', DB-
2 ', wear testing is carried out to its blade part using friction wear testing machine, the wear extent of its 30min is tested, the results are shown in Table 2.
The anti-wear performance test result of table 2
| Rotary Tiller Blade | The abrasion weight of 30min |
| DP-1’ | 0.1214g |
| DB-1’ | 0.6112g |
| DP-2’ | 0.1105g |
| DB-2’ | 0.6023g |
The anti-wear performance significantly larger than ordinary blade of the blade for being provided with alloy wear-resisting layer, energy are can be seen that by data in table 2
The friction cuttings of hard thing are enough resisted, to the fly-cutting of hard stubble root when cultivating, the service life of blade significantly extends.
Found after carrying out use on the spot in North China's corn field, common rotary blade cultivates about 200 mu or so, its
Blade part serious wear, cannot use；Blade of the present invention cultivates about 1600 ~ 1700 mu, and its blade part just wears up to cannot be used
Degree, the service life of blade greatly prolongs.
The foregoing is only presently preferred embodiments of the present invention, all impartial changes done according to scope of the present invention patent with
Modification, should all belong to covering scope of the invention.
