Description
Technical field
The utility model relates to grain header, particularly a kind of grass crushing mechanism rotary cutter that is applicable to combine.
Background technology
The dead knife that the rotating knife that the grass crushing mechanism of combine consists of a combination cutter and a row are fixed on jacket inwall forms, as, application publication number is the disclosed a kind of anti-swaging clamp grass crushing mechanism of the patent application of CN102696363A, comprise broken hayloft, rotor, on the circumference of rotor, be distributed with grass-smashing reamer, rotor is connected with driving mechanism, rotor is provided with several tool rests, this tool rest is provided with a cutter shaft, cutter shaft and described grass-smashing reamer are rotationally connected, it between grass-smashing reamer and cutter shaft, is matched in clearance, in described broken hayloft, be provided with the fixed blade of asking in grass-smashing reamer.
The grass-smashing reamer of this kind of grass crushing mechanism is to be generally fixed on singly rotor by welding or thread connecting mode, therefore, comparatively loaded down with trivial details during assembling, also unusual elapsed time.
Utility model content
The purpose of this utility model is to provide a kind of grass crushing mechanism rotary cutter that is applicable to combine, has assembling simple, is beneficial to the advantage that improves efficiency of assembling.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of grass crushing mechanism rotary cutter that is applicable to combine, comprise installation shaft and be located at several cutting tools of described installation shaft, it is characterized in that: the central part of cutting tool is provided with the installing hole of joining with installation shaft, described cutting tool is long waist shaped, upper and lower mirror image is provided with two blades, described blade bilateral has inclined-plane, on described inclined-plane, is provided with cutting teeth.
The setting on inclined-plane, make blade edge comparatively sharp, easily cut off stalk, and after blade incision stalk, the thickness that makes the both sides in described blade lengths direction due to inclined-plane, along the middle part of described blade to edge direction attenuation gradually, therefore has along the active force of stalk axial separation stalk; And because the above-mentioned of cutting teeth is obliquely installed, make the time of contact of cutting teeth and stalk relatively long, thereby improve broken careless effect.
As a kind of preferred, place, described installation shaft one end has screw thread, and is being fixedly installed barrier disc away from this end place; Described cutting tool is socketed on described installation shaft; This kind of grass crushing mechanism rotary cutter also comprise be socketed on described installation shaft and the lining between adjacent described cutting tool, be socketed on described installation shaft pad, be threadedly connected to described installation shaft and for described cutting tool and described lining are anchored on to the nut between described barrier disc and described pad.
Above-mentioned setting installed simply, and the angle that adjacent cutting tool length direction forms is easy to regulate, and can regulate the quantity of cutting tool according to the lining of the different thickness of selection, thereby is conducive to improve broken careless effect.
As a kind of preferably, the diminishing revolving fragment of distance between the both sides of described blade on comprising along described installing hole to outer extreme direction length direction, be located at the cutting teeth of described revolving fragment length direction both sides; Both sides on described revolving fragment length direction have inclined-plane, thereby the thickness that makes the both sides on described revolving fragment length direction is along the middle part of described revolving fragment to edge direction attenuation gradually; Described cutting teeth is located at described inclined-plane; And described cutting teeth near the one end at described revolving fragment middle part compared with the other end further from described installing hole.
As a kind of preferred, the angle that the length direction of described cutting teeth and described revolving fragment length direction form is 75-85 degree.
As a kind of preferred, described installation shaft is prism-shaped.
Avoid cutting tool to produce radial displacement in process process.
As a kind of preferred, the cross section of described installation shaft is hexagon.
To sum up, the utlity model has following advantage: the utility model is simple in structure, easy to implement, and assemble, dismantle simply, improved efficiency of assembling, reduced maintenance difficulty.
