Description
Technical field
The present invention relates to a kind of cutter, relate in particular to a kind of built-in ditching machine cutter of northern bioreactor that is applicable to.
Background technology
Although it is comparatively successfully confirmed that bioreactor technology has obtained in the large-area applications of China, but to the particularly area of application of external bioreactor in application of mechanization equipment, peasant household can liberate heavy physical labor in the urgent need to one, the utility machine makeup that can realize do mechanization operation is standby, not matching of mechanization equipment, makes this technology form bottleneck in the application of northern area.And the trench digging shape of trenching cutter in the past as shown in Figure 1, cutter type is similar to the cutter type of rotovator, width, the degree of depth of its trench digging are all inadequate, and be del 14, this be by by cutter to raise angle inadequate, native naturally the falling after rise of ditching, make to be configured to del, the end of ditch, is inadequate along size, and working resistance is large when Tool in Cutting soil like this, and the power of consumption is large.Power is not applied to the most concentrated place of stress, and reactive power consumption is larger.To be shaped as inverted trapezoidal 15 different from desired trench digging in actual production for these, so can not meet the needs of production.
Summary of the invention
The invention provides the built-in ditching machine cutter of a kind of northern bioreactor in order to solve the problems of the technologies described above, object is to strengthen bottom of trench width, reduces the thickness of backfill soil, working resistance and reactive power consumption while reducing Tool in Cutting soil.
For reaching the built-in ditching machine cutter of above-mentioned purpose the present invention north bioreactor, comprise propeller shaft sleeve, be provided with the first from left ditching knife and the second from left ditching knife in the left side of propeller shaft sleeve shell, middle part be respectively equipped with in a ditching knife and in two ditching knifes, right side is provided with a right ditching knife and right two ditching knifes, the angle of the first from left ditching knife and the second from left ditching knife is 180o, in a ditching knife and in the angle of two ditching knifes be 180o, the angle of a right ditching knife and right two ditching knifes is 180o, the first from left ditching knife with in the projection angle of a ditching knife be 60o, a right ditching knife with in the projection angle of a ditching knife be 60o, the projection angle of a right ditching knife and the second from left ditching knife is 60o, in the projection angle of two ditching knifes and the second from left ditching knife be 60o, in the projection angle of two ditching knifes and right two ditching knifes be 60o, the projection angle of the first from left ditching knife and right two ditching knifes is 60o, above-mentioned ditching knife is by the handle of a knife cover being located on propeller shaft sleeve, is inserted in the handle of a knife that handle of a knife puts and the blade that is fixed on handle of a knife end and forms.
Handle of a knife is fixed on handle of a knife with lock screw and puts.
The working face of blade is curved surface.
Curved surface is Archimedes spiral, formula r=a θ, wherein a=3mm, θ=180 °～220 °.
The side of blade is side tool sword, is positive blade before blade, and the angle between positive blade and ground is the clearance angle β that buries, and the angle between side tool sword and ground is penetrating angle α.
The clearance angle of burying β is 8 °, and penetrating angle α is 25 °-50 °.
The width of positive blade is 4.5cm, and side thickness of knife edge is 2mm.
The setting party of the curved surface of all blades is to identical.
The end of handle of a knife is fixedly connected with the back side of blade.
Propeller shaft sleeve is hexagon.
Advantageous effect of the present invention: the present invention is simple in structure, easy for installation, trench digging is thrown soil nature can be good, operating efficiency is high, meet the requirement of built-in bioreactor trench digging, realize the mechanization of built-in bioreactor trench digging, solved and hindered the bottleneck problem that this advanced technology of bioreactor is promoted.The curved surface of blade is taked Archimedes spiral, and raising native function increases greatly; The reasonable in design clearance angle β that buries, buries rapidly cutter, reduces useless power; The rational penetrating angle α of design, controls the height of digging; Trench digging process, due to the continuous variation of penetrating angle, has adapted to the trench digging of different soil.Make to ditch resistance and soil disturbance reduces greatly.The minimum of a value that the area of blade reaches capacity, available power reaches maximum.The layout of blade has guaranteed working stability and cutter shaft load evenly.
