Abstract
A self-sharpened wave ploughshare features that the upper working surface of its cutting knife has slots parallel to the hypotenuse edge of triangular area at the tip part of ploughshare to make the upper working surface in wave shape. It is possible to weld antiwear alloy in said slots. Its advantages are self-sharpening its wave-shaped cutting edge, low resistance and long service life.
Description
The present invention relates to power traction and plough the ploughshare of plough, particularly is a kind of self-sharpening share.
Existing scalpriform self-sharpening share, the ploughshare sword is thin than the ploughshare back of the body, need not put the first edge on a knife or a pair of scissors, and in use grinds cutting edge automatically, and keeps cutting edge sharp, thereby tillage resistance is little, need not often change ploughshare, can save steel and labour cost.But find in long-term the use that existing self-sharpening share still exists the cutting edge of wearing into automatically sharp inadequately, it is bigger to plough resistance, and the ploughshare life-span is permanent inadequately, is not suitable in stiff soil shortcomings such as operation.
Purpose of the present invention will provide exactly that a kind of autogenous grinding ploughshare sword is sharper, tillage resistance is littler, the self-sharpening share of longer service life.
For finishing the self-sharpening share that the invention task designs, the ploughshare sword is thin than the ploughshare back of the body, on the blade of ploughshare working face have be parallel to share beak trigonum hypotenuse, the groove of direction of advance when being the ploughshare operation, last working face undulate.
Ploughshare of the present invention since working face have rolling form be parallel to share beak trigonum hypotenuse, the groove of direction of advance when being the ploughshare operation, therefore be dentation, waveform from the cutting edge of wearing into, very sharp, soil-entering resistance reduces significantly, and the Tu Fa that cuts is directed smooth and easy mobile along working face groove on the ploughshare, and resistance is littler.Working face is a waveform on the ploughshare in addition, and cutting the soil upturned soil end of turning over also is waveform, the agro-farming requirement that meets actual situation and deposit.
Be further to improve service life and sword tooth sharpness, can be in the groove on the 65 manganese steel ploughshare working faces alloy of the high chromium of crossheading build-up wear-resistant material ploughshare, and bulk heat treatmet makes ploughshare hardness reach 40-45HRC, the high-abrasive material hardness 〉=60HRC of built-up welding.
Embodiment describes the present invention below in conjunction with accompanying drawing.
Fig. 1 is an embodiment of the invention schematic diagram.
Fig. 2 is cutting edge schematic diagram behind the ploughshare build-up wear-resistant material of the present invention.
Fig. 3 is that self-sharpening share of the present invention is from roll flute ripple sword schematic diagram.
As shown in Figure 1, parallel share beak trigonum 1 hypotenuse 2 is arranged, the groove 3 of direction of advance A when being the ploughshare operation on the blade of self-sharpening share of the present invention on the working face 4, last working face 4 undulates, cutting edge 5 does not put the first edge on a knife or a pair of scissors during making, during farming from wearing into sword.
As shown in Figure 2, on 65 manganese steel self-sharpening shares in the groove 3 on the working face 4 alloy of the high chromium of build-up wear-resistant material ploughshare to cutting edge 5.In the operation use, because of 65 manganese steel wearabilities are lower than alloy of high chromium, ploughshare is that nature grinds tooth wavy cutting edge 7, remains fluted 3 and go up on the working face 4.
Claims (2)
1, a kind of self-sharpening share, the ploughshare sword is thin than the ploughshare back of the body, it is characterized in that working face has the share beak of being parallel to trigonum hypotenuse, i.e. the groove of direction of advance during ploughshare operation, last working face undulate on the blade of said ploughshare.
2, self-sharpening share according to claim 1, it is characterized in that said ploughshare material is 65 manganese steel, alloy of the high chromium of high-abrasive material ploughshare that built-up welding is arranged in the groove on share beak and the ploughshare working face, bulk heat treatmet rear ploughshare hardness is 40-45HRC, the high-abrasive material hardness 〉=6OHRC of built-up welding.
