Abstract
The utility model relates to a kind of interior hinge formula mower knife assembly, comprise the cutting blade be installed on cutter shaft, the two ends outer wall of described cutter shaft is provided with bracing ring by support bar respectively, be connected between two bracing rings described cutting blade, the central shaft of the relative cutter shaft of multiple cutting blade is arranged symmetrically with, the inclined of the relative cutter shaft of cutting blade is arranged, with multiple cutting teeth on cutting blade; The two ends outer wall of described cutter shaft is symmetrically installed with inner blade respectively, and the middle part of cutter shaft is symmetrically installed with interior reamer.During utility model works, driven by engine cutter shaft High Rotation Speed, cut continuously weeds when cutting blade rolls, it is effective; Multiple cutting teeth structure is set, weeds are cut, avoid long weeds to be wound around cutting blade, reduce resistance; The relative cutter shaft of cutting blade is obliquely installed, and it is once less with the contact area of weeds, thus reduces Cutting Drag, improves cutting speed; Inner blade and interior reamer are set on cutter shaft, improve cutting efficiency, reduce mowing resistance further.
Description
Technical field
The utility model relates to technical field of agricultural machinery, especially a kind of hand-held rotovator.
Background technology
Mower be a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., it is made up of cutterhead, engine, road wheel, running gear, blade, handrail, control section.Cutterhead is contained on live axle, and cutterhead is equipped with engine, and the output shaft of engine is equipped with blade, and blade utilizes the High Rotation Speed of engine to carry out mowing operation, and its speed is fast, save the activity duration, decrease a large amount of human resources.
In existing mower, the structural design of its hay knife is reasonable not, and mowing efficiency is not high, blade is fragile.
Utility model content
The applicant, for the medium shortcoming of above-mentioned existing production technology, provides a kind of rational in infrastructure, interior hinge formula mower knife assembly that operating efficiency is high.
The technical scheme that the utility model adopts is as follows:
Hinge formula mower knife assembly in a kind of, comprise the cutting blade be installed on cutter shaft, the two ends outer wall of described cutter shaft is provided with bracing ring by support bar respectively, be connected between two bracing rings described cutting blade, the central shaft of the relative cutter shaft of multiple cutting blade is arranged symmetrically with, the inclined of the relative cutter shaft of cutting blade is arranged, with multiple cutting teeth on cutting blade;
The two ends outer wall of described cutter shaft is symmetrically installed with inner blade respectively, and the middle part of cutter shaft is symmetrically installed with interior reamer.
Further improvement as technique scheme:
The cross section of described cutting teeth is triangle.
Described cutting blade comprises four pieces.
Described inner blade comprises three pieces and the central shaft of cutter shaft is arranged symmetrically with relatively.
Described interior reamer is disc-shaped structure, with drag reduction hole on its reamer tooth.
The beneficial effects of the utility model are as follows:
During utility model works, driven by engine cutter shaft High Rotation Speed, cut continuously weeds when cutting blade rolls, it is effective; Multiple cutting teeth structure is set, weeds are cut, avoid long weeds to be wound around cutting blade, reduce resistance; The relative cutter shaft of cutting blade is obliquely installed, and it is once less with the contact area of weeds, thus reduces Cutting Drag, improves cutting speed; Inner blade and interior reamer are set on cutter shaft, improve cutting efficiency, reduce mowing resistance further.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Fig. 2 is front view of the present utility model.
Wherein: 1, cutter shaft; 2, bracing ring; 3, support bar; 4, cutting blade; 41, cutting teeth; 5, inner blade; 6, interior reamer; 61, drag reduction hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, the interior hinge formula mower knife assembly of the present embodiment, comprise the cutting blade 4 be installed on cutter shaft 1, the two ends outer wall of cutter shaft 1 is provided with bracing ring 2 by support bar 3 respectively, be connected between two bracing rings 2 cutting blade 4, cutting blade 4 comprises four pieces and the central shaft of cutter shaft 1 is arranged symmetrically with relatively, and the inclined of the relative cutter shaft 1 of cutting blade 4 is arranged, and namely cutting blade 4 entirety is in encircling shape anatomical connectivity on bracing ring 2; For improving cutter dynamics and efficiency, with multiple cutting teeth 41 on cutting blade 4, the cross section of cutting teeth 41 is triangle.
The two ends outer wall of cutter shaft 1 is symmetrically installed with inner blade 5 respectively, the middle part of cutter shaft 1 is symmetrically installed with interior reamer 6, inner blade 5 comprises three pieces and the central shaft of cutter shaft 1 is arranged symmetrically with relatively, interior reamer 6 is disc-shaped structure, with drag reduction hole 61 on its reamer tooth, drag reduction hole 61 is for reducing the Cutting Drag of inner blade 5.Inner blade 5 and interior reamer 6 are respectively used to weeds residual between and cutter shaft 1 outer wall inner to cutting blade 4 and carry out rubbing cutting, avoid being wound around, reduce resistance.
During utility model works, driven by engine cutter shaft High Rotation Speed, cut continuously weeds when cutting blade rolls, it is effective; Multiple cutting teeth structure is set, weeds are cut, avoid long weeds to be wound around cutting blade, reduce resistance; The relative cutter shaft of cutting blade is obliquely installed, and it is once less with the contact area of weeds, thus reduces Cutting Drag, improves cutting speed; Inner blade and interior reamer are set on cutter shaft, improve cutting efficiency, reduce mowing resistance further.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
