Abstract
The present invention relates to a kind of agricultural machinery, particularly a kind of corn combine, by the material of wherein peeling link cutter blade being improved, thus substantially increasing the operating efficiency of this agricultural machinery.
Description
Technical field
The invention belongs to agricultural mechanical field, particularly relate to a kind of corn combine, especially relate to wherein cutting blade.
Background technology
Agricultural realizes mechanization on a large scale and modernization has been inevitable main trend, therefore the demand of agricultural machinery must be increasing, and due to agricultural machinery object and be standard component unlike industrial products, its impact along with weather, moisture, region etc. factor and different, therefore modern agricultural machinery unlike a few years ago, as long as cost is low, enough, but the range more and more focusing on applying, quality and durability degree.The blade routine of the corn picker of current use uses low quality carbide alloy; what even have uses cast iron; usually causing the skin of corn outsourcing to rupture in its production process owing to cutting not exclusively is not thoroughly residually wrapped in the subsequent parts such as bearing; thus cause stopping accident, and usually can mix blade residue in final products.Therefore, being badly in need of a kind of cost of invention is not very high relatively, but such agricultural machinery that intensity and hardness are all improved largely.
Summary of the invention
The object of the invention is to propose a kind of durability and all good corn combine of Disposal quality.
Realize especially by following technological means.
A kind of corn combine, comprises fuselage, road wheel, driver's cabin, reaping apparatus, ear-picking unit, apparatus for peeling off and straw chopping apparatus.
Described apparatus for peeling off comprises upper conveyor belt, lower conveyor belt, tool rest and cutting knife, and wherein, cutting knife adopts cermet to make, and described chemical composition is by weight percentage: TiC:8.8 ~ 16.2%, ZrC:3.2 ~ 3.8%, Cr
3b
2: 6.8 ~ 8.8%, Mo:8 ~ 12%, C:0.5 ~ 1.1%, Ni:12 ~ 16%, RE:0.02 ~ 0.10%, surplus is Co and inevitable impurity, and wherein the average grain diameter of TiC phase is 0.2 ~ 0.5 μm, and the average grain diameter of ZrC phase is 0.8 ~ 1.1 μm, Cr
3b
2the average grain diameter of phase is 0.12 ~ 0.22 μm.
As preferably, through following steps after described cutting knife is shaping.
(1) inserted in resistance furnace by the cutting knife semi-finished product after shaping and be warmed up to 890 ~ 930 DEG C, insulation 25 ~ 38min, is then placed in quenching oil and carries out chilling.
(2) inserted in deep cooling box by the semi-finished product of step (1) cool to room temperature and be cooled to-80 ~-110 DEG C, coming out of the stove after insulation 10 ~ 25min adopts the mode sprayed water with high pressure to return to room temperature.
(3) inserted in tempering furnace by the semi-finished product that step (2) obtains and be warmed up to 180 ~ 220 DEG C, be incubated after 1 ~ 1.8 hour, stove is as cold as room temperature, obtains grinder blade finished product.
effect of the present invention is:
1, by improving the composition of blade consumable accessory and preparation technology, its intensity and hardness being greatly improved, thus the total quality of this agricultural machinery is greatly improved.
2, by improving the component content of blade, especially the creationary rare earth RE rationally adding specified quantitative in cermet composition, the particle diameter of wild phase is made also to obtain conservative control, thus its intensity is increased, toughness also obtains corresponding improvement, coordinates the creative heat treating regime set out, this blade stiffness is greatly improved, and service life is improved significantly.
