Embodiment
Below in conjunction with accompanying drawing, to concrete being described below of the utility model seat:
Fig. 1 is the restrict stereogram of formula mower of the typical case who uses the utility model moving head.As shown in Figure 1, the headstock 1 of beating the grass is installed on the mower output shaft of mower 100, one end of nylon rope 2 passes the nylon rope via hole on the headstock 1 of beating the grass and is fixed, the part that nylon rope exposes moving head is a working portion, and the nylon rope that exceeds protective cover 102 allowed bands can be excised automatically by the blade on the protective cover 102.
Fig. 2 is the exploded perspective view of the utility model moving head.As shown in Figure 2, the replaceable static line long dozen toothed burclover of a kind of formula mower of restricting of the present utility model comprises the headstock 1 of beating the grass, V-arrangement sheet 3, nylon rope 2, reinforcing ring 4, the skull 5 of beating the grass, locking nut 6, tapping screw 7 etc.
Fig. 3 is the utility model moving head upward view; Fig. 4 hides upward view behind the skull of beating the grass for the utility model moving head; Fig. 5 is the utility model moving head nylon rope via hole place partial enlarged drawing; Fig. 6 cuts front view for the utility model moving head open along nylon rope via hole and attachment screw place.
As Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, in the left-right symmetry of moving head a nylon rope via hole P is arranged respectively, nylon rope 2 is inserted by nylon rope via hole P, and the direction of arrow is the direction of insertion of nylon rope 2 among the figure.The side of nylon rope via hole P is flank wall W, its intensity is enough to make nylon rope to be close on it, the opposite side of nylon rope via hole P has two v-shaped cavity V that the parallel arranged shape is V-shaped, the both sides angle of v-shaped cavity V is a, the opening of v-shaped cavity V is towards nylon rope via hole P, nylon rope via hole P is led on one side of v-shaped cavity V, and the angle b of the direction of insertion of this limit and nylon rope 2 is slightly larger than 90 ° of angles.The another side afterbody of v-shaped cavity V has a stopping step T.The shape and the v-shaped cavity of V-arrangement sheet 3 are similar, and V-arrangement sheet 3 is made by rigidity, elasticity preferred metal material.V-arrangement sheet 3 is installed in the v-shaped cavity V, and a cephalic par of V-arrangement sheet 3 contacts with stopping step T, and the end, other end of V-arrangement sheet 3 reaches in the nylon rope via hole P, and between its end and flank wall W apart from s less than the minimum line of nylon rope 2 footpath.The angle that V-arrangement sheet 3 angle a0 between its both sides when free state will be a bit larger tham v-shaped cavity V both sides is a, and the V-arrangement sheet 3 after the installation has certain force of strain nylon rope 2 is pressed on the flank wall W, has prevented the free play of nylon rope 2.When nylon rope 2 when the direction of arrow is inserted from outside to inside, one side of V-arrangement sheet 3 will be to the swing of the inner space of v-shaped cavity V, it is big that distance between its end and flank wall W begins to become, nylon rope 2 be able to by, and when outwards spurring nylon rope 2 against the direction of arrow, the limit of V-arrangement sheet 3 begins to backswing moving, under the acting in conjunction of stopping step T, v-shaped cavity V inwall and flank wall W, V-arrangement sheet 3 tightens nylon rope 2 gradually, by locked, satisfy the demand of nylon rope suffered centrifugal force of when work and cutting reaction force etc. until nylon rope 2.Only need when nylon rope 2 needs to change internally that space I extracts the nylon rope that uses up out, and insert new nylon rope from outside to inside and get final product.The skull 5 of beating the grass is installed on the headstock 1 of beating the grass by tapping screw 7, with sealings such as nylon rope via hole P, v-shaped cavity V.Beating the grass is circular or cup-shaped after the skull 5 and headstock 1 assembling of beating the grass, and nylon rope 2 exposes by the inner space I of back from annulus or cup from nylon rope via hole P, and the size of inner space I is enough to make hand to put in nylon rope is taken out.For increasing the intensity of nylon rope via hole porch, also set up reinforcing ring 4 in the present embodiment, reinforcing ring 4 is stuck in beat the grass headstock 1 and 5 of the skulls of beating the grass.The headstock 1 of beating the grass is installed on the mower output shaft 8 by locking nut 6.
Two nylon rope via holes shown in the drawings, the side of each nylon rope via hole is established the example of two v-shaped cavities, but do not limit therewith, can be provided with 1,3 as required, even more nylon rope via hole, the v-shaped cavity of the side of each nylon rope via hole also can be provided with 1,3 as required simultaneously, even more.
More than announced the utility model with specific embodiment, so it is not in order to restriction the utility model, all employings equivalence is replaced or the technical scheme that mode obtained of equivalents, all drops in the protection domain of the present utility model.
