Description
Technical field
The utility model relates to a kind of gardens weeding machine, particularly a kind of mower moving head for lawn care.
Background technology
Fast development along with China's economy, people require constantly to strengthen to the ecological awareness and urban afforestation level, the public ecological green land in city, dwelling house greenery patches, Road Green Space etc. constantly increase, and traditional-handwork is pruned the needs that can not meet social development, and various mowers arise at the historic moment.The rope of beating the grass by High Rotation Speed during this machine work cuts the lawn, has rational in infrastructure, lightweight, the advantages such as volume is little, flexible and convenient operation, operating efficiency height, and extremely users' favor.But in use still have the following disadvantages: existing moving head and gear-box connecting portion gap are too large, in use, the moving head of High Rotation Speed can drive the and then moving head rotation of part grass, the connecting portion that grass is wrapped in moving head and gear drive casing can appear, cause the increase of moving head load, rotating speed to descend, moving head and gear-box temperature rise are increased fast, cause at last the moving head melting loss and can't use.For this reason, many manufacturers and knowledgeable people are studied and develop for the problems referred to above, but so far solution are preferably arranged not yet.
Summary of the invention
For overcoming existing existing the problems referred to above of mower moving head, the purpose of this utility model be to provide a kind of simple and reasonable, moving head and gear drive casing be connected that gap is little, grass can not be wound around, live load gently, the moving head mower moving head that can not generate heat.
the utility model solves the problems of the technologies described above the technical scheme that adopts, it comprises the gear drive casing, the gear-box over cap, the headstock of beating the grass, stage clip, rope sheave, impact head, cover cap, the gear-box over cap is fixed on the gear drive casing, the described headstock of beating the grass is fixed on the output shaft of gear drive casing, rope sheave and impact head are successively set in the headstock of beating the grass by fixed cap, be provided with top pressure spring between headstock and impact head beating the grass, beat the grass fake on rope sheave and stretch out from the rope hole of the headstock of beating the grass, the headstock of beating the grass is provided with the protruding guard circle that a circle covers the gear-box over cap, this projection guard circle is higher than gear-box over cap bottom.
The distance of described gear-box over cap and the headstock of beating the grass is less than 10 millimeters.
After adopting said structure; compared with prior art have the following advantages and effect: the one, owing to having increased on the headstock of beating the grass that a circle covers the protruding guard circle of gear-box over cap and higher than gear-box over cap bottom; when making the work of moving head High Rotation Speed; be wrapped in the connecting portion that grass on moving head can not enter beat the grass headstock and gear drive casing; thereby avoided grass to enter between moving head and gear drive casing; cause that moving head load increases, rotating speed descends, temperature rise is increased fast, cause at last the moving head melting loss and the problem that can't use.The 2nd, the distance between headstock and gear-box over cap of having reduced to beat the grass has further improved antiwind effect.
