As everyone knows, rearmounted motor mower is a kind of application electronic garden instrument very widely, and the usage amount of annual rearmounted motor mower is about 5,000,000 according to incompletely statistics, and the replacing of moving head number is especially remembered with ten million.The moving head of selling the rearmounted motor mower that uses in the market comprises the skull of beating the grass, the drum seat, be fixed on the connector on the output shaft, the rope of beating the grass, the unwrapping wire eye, wire spool, this structure output shaft drives the connector rotation, drive is beaten the grass to restrict and is rotated, realize mowing, the rope of beating the grass as easy loss, need constantly change by beaing of wire spool, have the following disadvantages in use: the one, change when beating the grass rope and whole moving head need be changed, cause not wearing detail such as drum seat, easy-to-damage element is not as the skull of beating the grass, the significant wastage of unwrapping wire eye and wire spool; The 2nd, the rope of beating the grass of this structure refills on the wire spool and is fitted on the drum seat is very complicated, and assembly difficulty is big; The 3rd, must be by specific purpose tool when changeing moving head, production cost height, inefficiency; Therefore the structure of this moving head remains further to be improved.For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but do not have desirable product to emerge in market so far as yet.

Summary of the invention

In order to overcome the existing above-mentioned disadvantage that formula unwrapping wire moving head exists of beaing, the purpose of this utility model provides a kind of simple and reasonable, easy for operation, efficiency of assembling is high, use cost is low, the economical and practical formula of beaing unwrapping wire moving head.

The utility model solves the problems of the technologies described above the technical scheme that adopts, it comprises the drum seat, connector, wire spool, the rope of beating the grass, spring, the skull of beating the grass, connector is arranged on the center adapter sleeve of drum seat, the rope of beating the grass is wrapped on the wire spool, described moving head covers and is provided with the outlet hangers that matches with drum seat outlet notch, the drum seat is provided with Elastic buckle, moving head covers and is provided with the bayonet socket that matches with Elastic buckle, wire spool is provided with to the contact of outer lug and is enclosed within on the center adapter sleeve of drum seat, spring is arranged between the contact and connector of wire spool, and the skull of beating the grass is enclosed within on the contact of wire spool and by Elastic buckle and bayonet fittings and is fixed on the drum seat.

Be with the outlet eye on the described outlet hangers, outlet hangers and outlet eye are provided with the notch that conveniently passes the rope of beating the grass, and the outlet notch of drum seat is provided with the line outlet convex tendon of sealing outlet hangers and outlet eye notch.

Described wire spool is provided with at least two around the upper protruding block of contact, and moving head covers to be provided with upper protruding block and intersects the skull projection of beating the grass that cooperates.

Described drum seat is provided with at least two around the lower protruding block of center adapter sleeve, and wire spool is provided with lower protruding block and intersects the wire spool projection that cooperates.

After adopting said structure, following advantage and effect are compared with prior art arranged: the one, because directly being contained in moving head, wire spool covers, the skull of beating the grass is fixed on the drum seat by Elastic buckle and bayonet fittings, greatly reduces assembly difficulty, and wearing detail provides necessary condition in order to save not; The 2nd, wearing detail can be recycled, greatly reduce use cost; The 3rd, dismounting is simple and convenient, does not need special-purpose dismantling device; The 4th, the purchase cost that has reduced the consumer namely need not be bought whole moving head and only buy a wire spool that winds nylon rope, and is economical and practical; The 5th, reduced environmental pollution.
