Abstract
The invention discloses a cutter head of a farmland ditcher. The cutter head comprises a rim, spokes, a shaft sleeve, cutter handles and the like, wherein a one-piece sealing cover is arranged on the outer side of the shaft sleeve at the center of the cutter head; a through hole is formed in the middle of the sealing cover. The invention also provides a manufacturing technical method for the shaft sleeve with the one-piece sealing cover at the center of the cutter head. According to the cutter head of the farmland ditcher, the shortcomings that the cutter head is easily installed in an inverted manner and an additional large gasket can easily lose during mounting of the cutter head in the prior art are overcome. The cutter head of the farmland ditcher is ingenious in structure; a forging manufacturing technology is easy, and relatively low in cost, and has a time-saving effect; furthermore, the surface of an inner hole of the forged shaft sleeve is high in intensity and has an anti-abrasion effect; the shaft sleeve with the one-piece sealing cover can be assembled and disassembled in a very convenient, quick and reliable manner.
Description
?
Technical field
The present invention relates generally to the cutter head for farm ditch digger technical field in agricultural machinery.
Background technology
Existing cutter head for farm ditch digger is made up of wheel rim, spoke, axle sleeve and handle of a knife etc., the inner hole of shaft sleeve at its center is divided into again cutterhead pilot hole and cutterhead locating hole from inside to outside, cutterhead pilot hole is interior cylindrical hole, and cutterhead locating hole is interior prism hole, sees Chinese invention patent CN2008101236158.Cutter-head of machine for making furrows coordinates installation by axle sleeve with the cutter axis on ditching machine gear-box, and cutter axis outer end is provided with thread, and cutterhead is loaded on pad after being installed on cutter axis, then with big nut, cutterhead is fastened on cutter axis.
The axle sleeve structure of this cutter-head of machine for making furrows, finds to exist following shortcoming: when the first, field furrower is sold, be loose piece, buy back assembling voluntarily by user in actual use; Adopt the cutterhead axle sleeve of this structure, most of user understands according to the structure of cutter axis and cutterhead axle sleeve, the pilot hole of cutterhead axle sleeve is first put to cutter axis, again the prism of the locating hole of cutterhead and cutter axis is worked good, generally difficult that cutterhead is anti-loaded, but thoroughly do not stop anti-loaded phenomenon, because user is peasant substantially, wherein have that a minority is older, technical merit is low, still can be carelessly by anti-loaded cutterhead use, once after cutterhead is anti-loaded, working load can significantly increase, the ditch shape of outputing is also very crude; The second, because the seam such as axle sleeve needs and spoke of cutterhead forms, the lower material of phosphorus content that therefore the necessary overall weldability of the material of axle sleeve can be good, and this has brought, surface of inner hole of shaft sleeve hardness is low, the flimsy shortcoming in prism hole, location of transmitting torque; Three, the manufacturing process complexity of existing cutterhead axle sleeve, processing cost is high; Four, the pad that cutter axis cover is equipped with near a side of nut is also easily lost in disassembly process, makes troubles to use.
Summary of the invention
Goal of the invention: for problem and the defect of above-mentioned existence, a kind of cutter-head of machine for making furrows of the present invention, has that intensity is high, good manufacturability, low cost and other advantages, and thoroughly stopped the anti-loaded phenomenon of cutterhead, install also more convenient simultaneously.
Technical scheme: to achieve the above object of the invention, the present invention is by the following technical solutions: a kind of cutter head for farm ditch digger, comprise wheel rim, spoke, axle sleeve and handle of a knife, described spoke is connected to form cutterhead main body along the setting of axle sleeve radiation mode and by axle sleeve and wheel rim, described handle of a knife is evenly distributed on wheel rim outer ring, an axial side of the axle sleeve at described cutterhead center is provided with the capping of disjunctor, and the centre of this capping is provided with through hole.
Described cutterhead axle sleeve adopts forging forming or casting.
Between described axle sleeve and capping, adopt welding or riveting method to be connected.
The outer lateral buckling of described capping is also fastened and connected with axle sleeve outside.
Beneficial effect: compared with prior art, the structure that cutterhead of the present invention adopts this axle sleeve to be connected with capping, just equal axle sleeve to be connected with pad processing and manufacturing simultaneously, user does not need separately to join pad in the time of dismounting again, so or else can there is the problem that pad is lost, install also more convenient; Because the through hole in the middle of capping is less, while conversely cutterhead being installed, cannot put the prism of cutter axis, thereby thoroughly stop the anti-loaded possibility of cutterhead; Axle sleeve adopts forging and stamping manufacturing process, one time, the interior prism hole excellent suitability for press forming of the interior cylindrical hole of assembling and square or other shape of transmitting torque, interior prism hole, no longer through machining, has retained the higher density of formation after forging and stamping and the superficial layer of hardness, improve intensity, not fragile; Excellent suitability for press forming not only technique simple, owing to having reduced the cutting process of metalworking, also save material, reduce costs.
