Description
Technical field
The utility model relates to farm machinery accessory field, is specifically related to a kind of for installing rotary blade roll shaft.
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 to seat, tool rest is arranged on cutter shaft.Cutter shaft is made primarily of seamless light 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 fall back to again on earth's surface.Unit constantly advances and to ravel to uncultivated land.
Because the tool rest quantity on cutter shaft is more, tool rest arrangement more complicated in addition, for casting, Mold Making is more difficult, and therefore roll shaft adopts welding procedure to make usually, and namely each tool rest is welded on roll shaft respectively; Simultaneously in order to reduce cost of manufacture, seamless pipe selected by cutter shaft, and welds spindle nose respectively at seamless pipe two ends.When being welded on roll shaft by tool rest, because roll shaft is cylindric, fix tool rest during welding very difficult, tool rest is fixed inaccurate, and the angle that rotary blade can be caused to install deflects, and then affects the operating efficiency of rotary blade.
Now be badly in need of a kind of roll shaft as can be seen here, tool rest can be made to be fixed on fast and accurately on cutter shaft.
Utility model content
The purpose of this utility model is providing a kind of roll shaft, and tool rest can be made to be fixed on fast and accurately on cutter shaft.
For achieving the above object, the technical solution of the utility model is as follows:
For installing rotary blade roll shaft, comprise cutter shaft and tool rest, tool rest is connected on cutter shaft, described tool rest comprises for connecting the vertical connecting plate of rotary blade and the horizontal connecting plate for being connected cutter shaft, described horizontal connecting plate is fixedly connected with vertical connecting plate, described horizontal connecting plate is provided with the first connecting hole, and described vertical connecting plate is provided with the second connecting hole for being connected with rotary blade; Described cutter shaft comprises the spindle nose that hollow pipe and two are separately fixed at hollow pipe two ends, and this spindle nose is provided with pin-and-hole, and described hollow pipe is provided with screwed hole.
Operation principle and beneficial effect: in this roll shaft, horizontal connecting plate is fixedly connected with vertical connecting plate, when horizontal connecting plate is welded on cutter shaft, because the contact surface of horizontal connecting plate and cutter shaft is larger, the weld seam that horizontal connecting plate and cutter shaft are formed is longer, tool rest is welded more firm.The first connecting hole on screwed hole on hollow pipe and horizontal connecting plate, facilitate the location of horizontal connecting plate on hollow pipe, by bolt, horizontal connecting plate is fixed on hollow pipe fast and accurately, then horizontal connecting plate is being welded with hollow pipe, because horizontal connecting plate is firmly fixed by bolt in welding process, therefore in welding process, horizontal connecting plate can not deflect, therefore the contrast locating of tool rest on cutter shaft is more accurate.When tool rest is welded on after in aerial pipe, the bolt connecting level board and hollow pipe is pulled out, in the process of roll shaft work, screwed hole also plays the effect of exhaust, facilitates gas in hollow pipe and extraneous gas exchanges, overcomes hollow pipe due to two ends to seal, in the process of hollow pipe work, expanding because managing interior gas heating, affecting cutter shaft and rotating, and then affecting the operating efficiency of rotary blade.Pin-and-hole on spindle nose facilitates the support arm on spindle nose and rotovator to pass through pinned connection.
This roll shaft is fixed tool rest in advance by bolt, is then welded on cutter shaft by tool rest, realizes the quick and precisely location of tool rest, again because level board adds the fusion length of tool rest and hollow shaft, makes tool rest fixing more firm.
Further, described vertical connecting plate comprises the first vertical connecting plate, the second vertical connecting plate and the 3rd vertical connecting plate that connect successively, and this vertical connecting plate is S-shaped; First vertical connecting plate is provided with the first spacing hole, second connecting hole is positioned on the second vertical connecting plate, second vertical plate is also provided with the 3rd connecting hole, the aperture of described second connecting hole is less than the aperture of the 3rd connecting hole, 3rd vertical connecting plate is provided with the second spacing hole, and the aperture of the first spacing hole is less than the aperture of the second spacing hole.
When ting model rotary blade installed by needs, ting model rotary blade and the second vertical connecting plate are bolted, and bolt is through the second connecting hole; Mounting limit bolt on the first spacing hole, this caging bolt carries out auxiliary positioning to small-sized rotary tilling cutter.When large model rotary blade installed by needs, large model rotary blade and the second vertical connecting plate are bolted, and bolt is through the 3rd connecting hole, and mounting limit bolt on the second spacing hole, this caging bolt carries out auxiliary positioning to large-scale rotary blade.
This tool rest can install the rotary blade of different model as required as can be seen here, and has auxiliary positioning function to rotary blade.
Further, described second connecting hole and the 3rd connecting hole are bar hole, and bar hole is convenient when rotary blade and tool rest are fixed, and regulate the position of rotary blade and angle.
Further, described horizontal connecting plate is the arch shape matched with the external arc of cutter shaft, and the direct contact surface of horizontal connecting plate and cutter shaft is larger, when fixing horizontal plate and cutter shaft, convenient.
Further, described horizontal connecting plate is provided with plug welding hole, increases the solder joint of horizontal connecting plate and cutter shaft, tool rest is connected with cutter shaft more firm.
Further, described first connecting hole is horizontal bar hole, when facilitating horizontal connecting plate to be connected with hollow pipe, regulates the position of horizontal connecting plate, and then realizes the position regulating tool rest.
