Description
Technical field
This utility model relates to loosening tobacco leaves field, particularly relates to a kind of frame hurdle for tobacco threshing machine.
Background technology
Tobacco threshing is that blade is separated by the method utilizing physics with cabo, it is simple to follow-up process respectively.Threshing machine is operationally, beat dynamic the forging a knife of leaf roller strap to run up, first contact with forging a knife time in Nicotiana tabacum L. input machine, the impact forged a knife, dragging Nicotiana tabacum L. of then forging a knife moves ahead, and is sheared by stationary knife and the frictional force effect on frame hurdle, and this frictional force constitutes mastication forces with drawing force of forging a knife, being formed and tear Nicotiana tabacum L., Nicotiana tabacum L. is separated into blade and cabo under the effect beaten and tear.
Nowadays changing tobacco shred existing structure and quality, be high speed cigarette and ramuscule cigarette process new demand, if long filament rate is higher, easily there is ring " cigarette " in coiling process.Because sheet leaf diameter determines cut tobacco length, want to solve that " joint cigarette " this problem occurs, preferred plan is to be diminished by sheet leaf from source, the pass of past threshing machine frame bar mostly is shape hole, mound, circular port or T-shaped hole, and above-mentioned frame hurdle is during using, and its blade wherein sheet pick-up rate obtained is relatively low, its broken rate is higher, do not meet cigarette machine ramuscule cigarette technological requirement, therefore promote to improve the pass on frame hurdle, with sheet occupation rate in obtaining preferably.
China Patent Publication No. is CN203692513U, patent name is " the regular hexagon loosening tobacco leaves machine frame hurdle of a kind of band cutting edge ", disclose a kind of threshing machine frame bar, its pass is regular hexagon, and edge, aperture is provided with cutting edge, although the frame hurdle of this kind of pass compares sheet occupation rate during prismatic hole can preferably obtain during using, but the most easily grind at blade, cause hexagonal hole deformation after use a period of time, in turn result in frame hurdle to be substantially reduced service life, and the most easily make broken, but frame hurdle mastication forces between Nicotiana tabacum L. and frame hurdle during using is unsatisfactory, the occupation rate of middle improves less.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of frame hurdle for tobacco threshing machine, purpose is that the frame hurdle solving regular hexagon pass structure the most easily grinds at blade during using, cause hexagonal hole deformation after use a period of time, in turn result in frame hurdle to be substantially reduced service life, and the most easily make broken, but frame hurdle mastication forces between Nicotiana tabacum L. and frame hurdle during using is unsatisfactory, and the occupation rate of middle improves less problem.
Its technical scheme is, including frame hurdle matrix, described frame hurdle matrix is provided with orthohexagonal cell orifice, described cell orifice is staggered on frame hurdle body to be uniformly distributed, the cutting edge being obliquely installed it is provided with at cell orifice inside edge, the inclined-plane of described cutting edge is provided with recessed notch, described notch lower end extends to the lower surface of frame hurdle matrix, the upper end of described notch extends to the upper surface of frame hurdle matrix, described notch arranges along the inclined plane length direction of cutting edge and forms array, the surface of described notch be provided with there is rough surface tear layer.
Described frame hurdle matrix is that 16Mn steel is made, and its inscribed circle diameter of described cell orifice is 76.2mm, and each adjacent cells hole array forms the structure of approximation splicing, being uniformly interspersed described in formation.
Its cross section of described notch is semicircular structure.
Described notch is close to distribution in the inclined plane of cutting edge, and the described layer that tears is that corundum even adhesion forms described rough surface on cutting edge.
This utility model simple in construction, utilize corundum wearability and rough surface strengthen the mastication forces between smoked sheet and frame hurdle, the intersection of notch and frame hurdle matrix forms the tear edge of arc simultaneously, strengthen the mastication forces between Nicotiana tabacum L. and frame hurdle further, the concave shaped structure of another notch, increase and tear the action face of layer and amass, strengthen smoked sheet and tear area when contacting with frame hurdle.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
nullEmbodiment one: as shown in Figures 1 to 4，A kind of frame hurdle for tobacco threshing machine，Including frame hurdle matrix 1，Described frame hurdle matrix 1 is made for 16Mn steel，For obtaining more preferable toughness and intensity，Described frame hurdle matrix 1 is provided with orthohexagonal cell orifice 2，Described cell orifice 2 is staggered on frame hurdle body to be uniformly distributed，Described its inscribed circle diameter of cell orifice 2 is 76.2mm，Each adjacent cells hole 2 array forms the structure of approximation splicing，Being uniformly interspersed described in formation，Namely each unit hole 2 to arrange orientation identical，It is spaced discounting between cell orifice 2，Each unit hole 2 only relies on translational motion，Complete splicing can be realized，The cutting edge 3 being obliquely installed it is provided with at cell orifice 2 inside edge，The inclined-plane of described cutting edge 3 is provided with recessed notch 4，Described its cross section of notch 4 is semicircular structure，Described notch 4 lower end extends to the lower surface of frame hurdle matrix 1，The upper end of described notch 4 extends to the upper surface of frame hurdle matrix 1，Described notch 4 arranges formation array along the inclined plane length direction of cutting edge 3，The surface of described notch 4 be provided with there is rough surface tear layer，Described notch 4 is close to distribution in the inclined plane of cutting edge 3，The described layer that tears is that corundum even adhesion forms described rough surface on cutting edge 3.
