Description
Technical field
The utility model relates to a kind of agricultural and gardens cutting mechanics, specifically is revolving blade and the cutting machine that this revolves the cutting plants bar stem of blade being housed of a kind of cutting plants bar stem.
Background technology
Existingly cut rice, cut wheat, blade such as mowing is generally up and down two groups of shearing blades or the disc sawtooth revolves blade, the former is complicated to the cutting mechanics structural requirement, and generally only be adapted to large-scale rice/wheat combine, and the wearing and tearing of blade are very fast, the axis of minor diameters such as the latter then generally only is adapted to mow, standing grain, and therefore diameter, thickness and the tooth depth of blade be subjected to its blade shapes restriction and less approach lower, so it is then easily damaged to meet hard, thick thing slightly, in a word, certain limitation is all arranged in both scopes of application and service life.In production practices, do not find a kind of plant that can cut soft relatively paths such as paddy and wheat, grass as yet, more can cut the blade that revolves of thick and stiff plants such as reed, jute, jowar, rape, soybean bar.
The existing paddy and wheat machine that cuts, general structure is complicated, and only is adapted to cut paddy and wheat, and existing mower generally is the electric slicer of shoulder back of the body type, adopts the mowing band or the disc sawtooth of rotation to revolve blade cuts, and its shortcoming is, labour intensity is big, and operation is effort very, and only limits to mow; The report of the Hand-push-down machine for mowing off straws of crops of shaft-like crops such as cutting rape, soybean was once arranged, but still had defectives such as labour intensity is big, efficient is low.In production practices, do not find equally as yet a kind ofly can cut relatively little soft axis such as paddy and wheat, grass, can cut thick and stiff plant (crops) bars such as reed, jute, jowar, rape, soybean bar and simple in structure, easy to operate, laborsaving, the cutting machine of cutting plants bar stem efficiently again.
The utility model content
A technical problem to be solved in the utility model is, overcomes the defective of above prior art, and a kind of blade that revolves of the cutting plants bar stem that cuts various plant stalks and long service life is provided.
Another technical problem to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of and cuts various plant stalks and simple in structure, rapid operation, convenience, efficiently the above-mentioned cutting machine that revolves the cutting plants bar stem of blade is housed.
A technical solution of the present utility model is, a kind of blade that revolves of cutting plants bar stem is provided, it comprises the centre bore that usefulness is installed, describedly revolve being shaped as of blade: three to six sickleshaped blades are arranged on the excircle of circular base, on the external arc limit of sickleshaped blade a plurality of sawtooth are arranged, described sickleshaped blade and circular base are as a whole, every head the sickleshaped blade radially outward stretches, adjacent last be the afterbody of sickleshaped blade and back circumferential breach forming a radial groove between the head of sickleshaped blade.
Described sickleshaped blade is preferably four, and evenly distributes along 360 degree circumference; The described every head of sickleshaped blade is radially outward stretched refers to stretch along round cross centre line straight line, and a side of described circumferential breach is a straight flange.
Another technical solution of the present utility model is, a kind of above-mentioned plant stalk cutting machine that revolves blade that is equipped with is provided, it comprises frame, wheel, engine etc., describedly revolve the lower end that the blade level is installed in the power machine axis of being located at the frame front lower place, two inboard afterbody circumference with the sickleshaped blade that revolves blade of two fixed blades of double guiding fork are tangent, and place on the frame of revolving blade below or top, described two fixed blades revolve blade center's axis or slightly outward-dipping angle is extended to the direction that deviates from engine to be parallel to.
Described wheel can be the iron tyre that adapts to paddy field and wetland walking; The described wheel can drive walking through transmission mechanism by engine.
After adopting above structure, the utility model compared with prior art has the following advantages:
This cutting plants bar stem revolve the distinctive shape of blade and radial groove is the design of circumferential breach, make the plant stalk that head-on enters blade, regardless of different kinds of soft or hard all at first fall into groove and breach, the blade with high speed rotating is cut off rapidly then, applicable surface is very extensive; And the revolving blade and can make blade diameter design bigger of this shape, and corresponding thickness is arranged, tooth depth is also higher, is difficult for very quick-wearing or damaged, and its service life is longer.
The above-mentioned cutting machine that revolves the cutting plants bar stem of blade originally is housed, structure is very simple, both can cut little soft axis such as paddy and wheat, grass, can cut thick and stiff plant bars such as reed, jute, jowar, rape, soybean bar again, adaptive surface is very extensive, and rapid operation, convenience have reduced labour intensity significantly, have greatly improved labor productivity.
