Abstract

The utility model relates to a grass mowing head winding a rope automatically, and belongs to a weeding device. A portal type iron piece is connected with a portal type rabbet in an inserted mode, a lower disc comprises the portal type rabbet, a heat dissipation groove, a third limiting block, a center hole and a clamping groove, an upper disc comprises a clamping tongue, a spring, a portal type opening and a screw hole, and the spring is positioned in the upper disc. A center wheel comprises a first limiting block, a second limiting block, a rope threading hole, a heat dissipation hole, a first limiting plate, a second limiting plate and a third limiting plate, wherein the center wheel is connected with the center hole in an inserted mode, the second limiting block is connected with the third limiting block in a clamping mode, the first limiting block is connected with the interior of the upper disc in a clamping mode, the clamping tongue is connected with the clamping groove in a clamping mode, and the spring is connected with the center of the upper end of the center wheel in a pressed mode. The grass mowing head has the advantages of being novel in structure, achieving rope winding free of disassembly, greatly improving working efficiency, prolonging service life of the center wheel, and being free of deformation in high-speed rotation, high in safety and good in heat dissipation and balance, a common user can operate the grass mowing head, the grass mowing head does not burn and disengage the rope, and the rope is easy to pull out.

Description

A kind of moving head of automatic rope woolding

Technical field

The utility model belongs to a kind of weeder, refers in particular to a kind of grass cutter.

Background technology

The current moving head used is comprised of round box and a centre wheel that nylon rope is housed, during work, centre wheel drives nylon rope fast rotational together, in the fast rotational process, by nylon rope, grass is interrupted, but present moving head, the ironware at centre wheel place easily grinds rope, centre wheel in the High Rotation Speed process because internal heat is too high, the rope phenomenon appears burning, easily take off rope while telling rope, when rope woolding, due to twining of a manual circle circle, situation about having some setbacks easily appears, and the older and not yet done user of use often supports the main points of holding bad rope woolding, cause not installing.

Summary of the invention

The utility model provides a kind of moving head of automatic rope woolding, and to solve existing moving head, the ironware at centre wheel place easily grinds rope, too high being prone to of internal heat burnt the rope phenomenon, easily take off rope while telling rope, having some setbacks easily appears in rope woolding, the problem of using not yet done user installation not go up.

The technical solution of the utility model is: door sections sheet is pegged graft with door type notch, and lower wall comprises a type notch, radiating groove, limited block three, centre bore, draw-in groove, centre bore is positioned at the lower wall middle part, and lower plate edge has radiating groove, and wherein the radiating groove place relative with centre bore, two positions has respectively draw-in groove, and upper dish comprises block tongue, spring, door type opening, screw, it is inner that spring is positioned at dish, and be fixedly connected with upper dish inside center, and screw is positioned at dish top center position, and centre wheel comprises limited block one, limited block two, lacing hole, louvre, limiting plate one, limiting plate two, limiting plate three, limiting plate one is fixedly connected with the centre wheel upper strata of hollow, limiting plate two, limiting plate three is positioned at the below of limiting plate one successively, distance between limiting plate one and limiting plate two equates with the distance between limiting plate two limiting plates three, lacing hole is through hole, is positioned on limiting plate two, and limited block one is fixedly connected with limiting plate one upper surface, limited block two is fixedly connected with limiting plate three lower surfaces, centre wheel and centre bore are pegged graft, limited block two and limited block three clampings, limited block one and the inner clamping of upper dish, block tongue and draw-in groove clamping, spring and the center crimping of centre wheel upper end.

The utility model has the advantage of: novel structure, realized exempting to dismantle rope woolding, domestic consumer all can be operated, greatly improved operating efficiency, improved the life-span of centre wheel, indeformable under High Rotation Speed, safe, thermal diffusivity is good, do not burn rope, tell rope easily, not de-rope, balance is good.
