Description
Technical field
This application involves agricultural machinery technological fields, and in particular to a kind of cutter for agricultural machinery.
Background technique
Cutter is the tool that machining is used in machine-building, also known as cutting element.Most of cutter is that machine is used
, but also have hand.The cutter as used in machine-building is substantially all for cutting object, so " cutter " is general just
It is interpreted as cutting tool.Cutter is very extensive in the application of agriculture field at present, such as common ploughshare when arable land, when mowing
Grass trimmer, when grain harvest cropper etc. used.However, during harvester work, since stalk exists
Can rub cutter when crushing, gradually wear out cutter, reduce the efficiency of agricultural machinery at work.
Domestic agricultural cutter is still based on monometallic material at present, and the generally existing hardness of domestic cutter, wearability are not
Problem high, service life is shorter, Chang Yinwei serious wear and cannot be used continuously completely；The damage of cutter largely collects in fact
In can often occur passivation at blade, at blade, even there is phenomena such as notch in serious wear.
To solve the above-mentioned problems, high rigidity cladding layer is set in the one side of blade in the prior art, due to cladding layer
Hardness is higher than the hardness of cutter metal, therefore the effect of blade autogenous grinding is realized in the use process of cutter.But due to cladding
Layer is directly covered in a face Integral melting of blade and is set, when cladding layer can generate friction with cutting object to cutter in cutting process,
It does not only result in frictional force when cutting to increase, with the time that uses of cutter, cladding layer is also easy to generation entirety and falls off, and leads to knife
Having wearability reduces.
Summary of the invention
In order to solve the above-mentioned technical problem the application, proposes following technical solution:
