Description
Technical field
The utility model belongs to mini-size tillage machine part field, particularly cultivated cutter assembly.
Background technology
Mini-size tillage machine has little, the lightweight and easy to operate feature of volume compared with large-scale agricultural ploughing machine, and therefore mini-size tillage machine is widely used in the nonirrigated farmland, paddy field, orchard etc. on Plain, mountain area, hills.Mini-size tillage machine freely can be exercised in field, user-friendly and deposit, and solves the worry that large-scale farm machinery cannot enter mountain area field, is the optimal selection that vast farmers consumer substitutes ox and ploughs.
Mini-size tillage machine research direction always makes mini-size tillage machine become less, more convenient, how cultivated cutter assembly as mini-size tillage machine key operation parts becomes the factor that must consider that carefulization is also mini-size tillage machine miniaturization, plough cutter assembly and mainly comprise cutter shaft, cutterhead and blade, generally that blade is fixed on cutterhead, cutterhead is being fixed on cutter shaft, cutter shaft is connected with the output shaft of actuating unit, cutter shaft is along with output shaft rotation, thus allow blade rotation realize breaing up of soil, large-scale farming machine unitary design still continued to use by the cutter shaft of present design, although unitary design is conducive to transmission, but be not easy to disassembled for transport and manufacture, and once cultivated cutter there is damage or buckling phenomenon appears in cutter shaft part, need the replacing of whole cultivated cutter, the mini-size tillage machine adopting integral type to plough cutter is made to there is the high problem of replacement cost.
Utility model content
The purpose of this utility model is to provide a kind of cultivated cutter assembly being convenient to local replacing, and solution adopts now integral type to plough cutter and damages the whole cultivated cutter replacing of needs, causes the problem that replacement cost is high.
To achieve these goals, the cultivated cutter assembly that the utility model provides, comprise multiple cultivated cutter monomer removably connected, the cutter shaft that described cultivated cutter monomer comprises linkage section that one end is tubulose, the other end is draw section, described draw section external diameter is less than the internal diameter of linkage section, draw section and linkage section is equipped with the connecting hole that radial direction runs through.
When assembling cultivated cutter assembly, connected successively by multiple cultivated cutter monomer by dismountable connector such as latch or bolt, latch can be extracted after cultivated cutter monomer damages, and realizes the replacing to cultivated cutter monomer.
The utility model has the advantage of: plough cutter assembly and be made up of multiple cultivated cutter monomer series winding, 1, can according to the mini-size tillage machine model size used, quantitative change is carried out to the cultivated cutter monomer on whole cultivated cutter assembly, what make to be formed completes the mating, to adapt to the needs of the mini-size tillage machine of different model of cultivated cutter and mini-size tillage machine.2, when one of them cultivated cutter on cultivated cutter assembly occurs damaging the operation that can replace with the new fast quick-recovery mini-size tillage machine of cultivated cutter monomer immediately.3, plough cutter monomer and can make standard component, to produce in batches, reduce production cost.
Further, described connecting hole coupling is provided with the latch be fixedly connected with by two cutter shafts, realizes being fixedly connected with of two cutter shafts, make cutter shaft connect so convenient because latch directly inserts in connecting hole; When dismantling, directly extract bearing pin.
Further, described latch comprises bearing pin and C shape is buckled, and one end that described C shape detains one end and bearing pin is hinged, and the C shape button other end can snap onto on bearing pin; Latch arranges C shape buckle, when latch inserts in connecting hole, by C shape button, bearing pin upper and lower side is carried out spacing, make bearing pin to drop out connecting hole, realize the firm connection that two plough cutter monomer.
Further, described cultivated cutter monomer also comprises cutterhead, and described cutter head center is provided with axis hole, and taper hole is led in described axis hole one end, and cutterhead welds with cutter shaft; Be welded and fixed as non-removable fixed form, add the stationarity of cutterhead and cutter shaft.
Further, described cutterhead is provided with groove, and described groove internal fixtion is connected with blade; Its effect is stuck in groove by whole for the installation portion of blade, makes the whole installation portion of blade all as localization part, improves the original problem using two Bolt to position easily to loosen; Because reeded existence, only need a positioning element allowing cutterhead and blade fit together.
Further, the depth of groove of described cutterhead is more than or equal to the installation portion thickness of blade; Make the installation portion of blade all be trapped in groove like this, even if blade is subject to the soil reaction force larger to it, groove also can ensure that blade can not skid off outside groove, ensure that the reliability of mini-size tillage machine operation.
Further, the groove of described cutterhead is provided with four and divides equally setting with axis hole circumference; Because mini-size tillage machine build is less, adopting four grooves, is namely employing four blades; Common soil adopts four blades can meet operation needs, and four grooves are also convenient to distribute blade needs arranged in a crossed manner.
Finally, described cutterhead and blade adopt a rivet to be fixed, because cutterhead is provided with groove, can by blade restriction in a groove by groove, make blade on cutterhead, sidesway can not occur, only need just blade to be carried out comprehensive fixing at a rivet simultaneously, this also reduces union piece, substantially reduce the loss of part.
Accompanying drawing explanation
Fig. 1 is the structural blast figure of cultivated cutter assembly intertillage cutter monomer;
Fig. 2 is the structural representation of cultivated cutter assembly;
Fig. 3 is the structural representation of latch.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by embodiment:
