Abstract
This patent belongs to rotary cultivator accessory field, specifically discloses a rotary blade, including back of a knife blade portion, cutting edge portion and handle of a knife portion, back of a knife blade portion and cutting edge portion are circular -arcly, and cutting edge position in the outer circular arc department of back of a knife blade portion, and cutting edge portion is the wedge. It is little that this rotary blade has a resistance of burying, can cut ruderal characteristics.
Description
Technical field
The utility model relates to rotovator accessory field, is specifically related to a kind of rotary blade.
Background technology
Rotovator completes cultivated, to harrow operation cultivation machinery.Because of its have hack ability strong, plough after the features such as earth's surface is smooth, and to be widely used; The root stubble being embedded in below earth's surface can be shredded simultaneously, be convenient to sower operation, well plant bed for later stage sowing provides.
Rotovator can be divided into horizontal shaft type (horizontal), vertical shaft type (vertical) and clino-axis type by the position of rotary ploughing cutter shaft; Towed, suspension type and direct-coupled type can be divided into by the connected mode with tractor; Intermediate transmission formula and side driven type can be divided into by the cutter shaft kind of drive.Side driven type can be divided into again side gear drive and side Chain conveyer two kinds of forms.
Rotovator is mainly made up of frame, transmission system, roll shaft, rotary blade, tilling depth adjusting device, case etc.Roll shaft comprises cutter shaft and tool rest, and tool rest is arranged on cutter shaft.Cutter shaft is made primarily of seamless steel pipe, and the two ends of axle are welded with spindle nose, and this spindle nose is connected with left and right supporting arms pin.Tool rest is arranged by spiral and is welded on cutter shaft for installing rotary blade; Tool rest is provided with the equal connecting hole of spacing, is convenient to require to install rotary blade according to agrotechnique.Rotary blade refers to: the rotovator accessory used with scratching for farmland, and profile is knife-like; Cutter shaft refers to: play a supportive role to rotary blade, and provides the rotovator accessory of power to rotary blade gyration; Tool rest refers to: one block of steel plate containing multiple connecting hole.
During rotovator work, rotary blade is driven by tractor motive power output shaft on the one hand and does gyration, and uniform rectilinear motion is in random groups advance on the other hand.Rotary blade, in cutting soil process, first cuts upturned soil, throw to and clash into case and grading planker in small, broken bits after falling back on earth's surface.Unit constantly advances and to ravel to uncultivated land.
Current rotary blade is one piece and waits steel plate to be made, the thickness in knife back portion and other positions are conformed to each others of blade, this rotary blade structure is simple, easy to make, but this rotary blade is arranged on when rotovator works, because the thickness at cutting edge place is equal with the thickness at other positions of blade, when then rotary blade buries, resistance is larger, now not only increase the power consumption of rotovator, also easily occur that weeds are wound around rotary blade, increase the resistance that rotary blade rotates.
Now be badly in need of the little rotary blade of a kind of soil-entering resistance as can be seen here.
Utility model content
The purpose of this utility model has the little rotary blade of soil-entering resistance providing a kind of.
For achieving the above object, the technical solution of the utility model is as follows:
Rotary blade, comprises knife back portion, blade part and shank section, and described knife back portion and blade part are arc-shaped, and blade part is positioned at the external arc place in knife back portion, and blade part is wedge shape.
Operation principle and beneficial effect: blade part and the knife back portion of this rotary blade are arc-shaped are that when facilitating rotary blade to work, blade part buries, and blade part rotates and cut off by weeds simultaneously.Blade part is wedge shape, and processing is than being easier to, and when burying, resistance is less.
Further, described shank section is provided with the first connecting hole and the second connecting hole, when shank section is fixed on tool rest, because shank section has two tie points, only has a tie point relative to the rotary blade transmitted, and fixing more firm, rotary blade rocks less.
Further, described second connecting hole is bar hole, facilitates rotary blade with when being connected, and is convenient to the position and the angle of penetration that adjust rotary blade.
Further, described knife back portion is provided with groove, when rotovator works, rotary blade ploughs the hard objects such as stone, because groove material thickness is the thinnest, stressed more energetically time, groove ruptures at first, now occurs breaking phenomenon, avoids because rotary blade is blocked by hard objects, cannot work, and occur the situation burning out dynamical system.
Further, described groove is dovetail groove, dovetail groove be convenient to processing, can directly on milling machine once milling complete.
Further, the width of described blade part is 2.5 centimetres, and the width of blade part is too small, then ability of burying is more weak, and the width of blade part is excessive, then easily occur the situation of broken edge, also larger simultaneously to processing and manufacturing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model rotary blade embodiment;
Fig. 2 is A-A profile in Fig. 1.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: knife back portion 1, blade part 2, shank section 3, first connecting hole 4, second connecting hole 5, dovetail groove 6.
Embodiment is substantially as shown in accompanying drawing 1, Fig. 2: rotary blade, comprise knife back portion 1, blade part 2 and shank section 3, knife back portion 1 and blade part 2 are arc-shaped, and blade part 2 is positioned at the external arc place in knife back portion 1, blade part 2 is wedge shape, shank section 3 is provided with the first connecting hole 4 and the second connecting hole 5, and wherein the first connecting hole 4 is circular hole, and the second connecting hole 5 is bar hole.Knife back portion 1 is provided with 3 grooves, and this groove is dovetail groove 6.
During concrete enforcement, the width of blade part 2 is 2.5 centimetres, and the thickness of knife back portion 1 and shank section 3 is 2 millimeters thick, and blade part 2, knife back portion 1 and handle of a knife are one-body molded.
Blade part 2 and the knife back portion 1 of this rotary blade are arc-shaped, are that when facilitating rotary blade to work, blade part 2 buries, and are cut off by weeds when blade part 2 rotates simultaneously.Blade part 2 is wedge shape, and processing is than being easier to.When rotavator knife works, when rotary blade ploughs the hard objects such as stone, because groove material thickness is the thinnest, stressed more energetically time, groove ruptures at first, now occurs breaking phenomenon, avoid, because rotary blade is blocked by hard objects, cannot working, and occurring the situation burning out dynamical system.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
