Summary of the invention:

The purpose of this utility model provides a kind of use, changes conveniently the simple and easy moving head that use cost is low.

The utility model is achieved in that

A kind of simple and easy moving head, loam cake is fixed on down and covers, the middle part of lower cover is provided with and raises up, the frustum of a cone of bottom opening, the upper surface of the frustum of a cone is provided with the moving head installing hole, be respectively arranged with on loam cake and the face that lower cover cooperatively interacts and cooperate the inlet wire groove that forms entrance hole, the inlet wire groove of lower cover is communicated with the rope locating slot of beating the grass, the corresponding wire hole that offers with entrance hole UNICOM on the frustum of a cone, the frustum of a cone of lower cover passes the center of loam cake, and the rope of beating the grass is positioned in the rope locating slot of beating the grass by lock dog.

Above-mentioned lock dog is provided with the strip hole, and the strip borehole jack is located on the reference column of rope in the locating slot of beating the grass, and is used to hold out against lock dog with the beat the grass spring of rope of pinning beating the grass to be provided with between rope locating slot and the lock dog.

Above-mentioned lock dog is an inclined-plane with the contact-making surface of the rope of beating the grass.

The above-mentioned rope of beating the grass is the toothed ropes of two opposite side.

The outstanding compared to existing technology advantage of the utility model is:

1, the utility model blocks the tooth of beating the grass on restricting by lock dog, the rope of will beating the grass is fixed on the moving head, the rope of will beating the grass after the rope of beating the grass is worn pushes away toward wire hole, rope is to lock dog power inward owing to beat the grass, make spring compress, the lock dog and the rope of beating the grass produce certain clearance between the locating slot, the rope of beating the grass that can will wear and tear in the wire hole of lower cover takes out, again can finish the rope replacing of beating the grass with pushing the rope of beating the grass the new entrance hole of rope from moving head of beating the grass then, and work on, change, install very convenient;

2, the utility model has been cancelled drum, and the rope of beating the grass does not need to be wrapped in the drum as traditional moving head, and causes the waste of the rope of beating the grass of certain-length, has saved use cost;

3, the utility model is applicable on the various mowers.

Embodiment:

With specific embodiment the utility model is further described below, referring to Fig. 1-9:

A kind of simple and easy moving head, loam cake 10 is fixed on the lower cover 30, the middle part of lower cover 30 is provided with and raises up, the frustum of a cone 304 of bottom opening, the upper surface of the frustum of a cone 304 is provided with moving head installing hole 303, be respectively arranged with on loam cake 10 and the face that lower cover 30 cooperatively interacts and cooperate the inlet wire groove 42 that forms

entrance hole

40,41, the inlet wire groove 41 of lower cover is communicated with the rope locating slot 302 of beating the grass, the corresponding wire hole 301 that offers with entrance hole 40 UNICOMs on the frustum of a cone 304, the frustum of a cone 304 of lower cover 30 passes the center of loam cake 10, and the rope 20 of beating the grass is positioned in the rope locating slot 302 of beating the grass by lock dog 60.

Above-mentioned lock dog 60 is provided with strip hole 601, and strip hole 601 is set on the reference column 70 in the rope locating slot 302 of beating the grass, is provided with to be used to hold out against lock dog 60 with pinning 20 the spring 50 of restricting of beating the grass between beat the grass rope locating slot 302 and lock dog 60.

Above-mentioned lock dog 60 is an inclined-plane with the contact-making surface of the rope 20 of beating the grass, and the rope 20 of can conveniently beating the grass pushes away from past wire hole 301 directions, thereby takes out the rope 20 of beating the grass like a cork.

The above-mentioned rope 20 of beating the grass is the toothed ropes of two opposite side, can conveniently the beat the grass installation of rope 20 of the two pairs of sideband teeth, tooth on the opposite side may be stuck on the lock dog 60, make the rope 20 of beating the grass be held out against in the rope locating slot 302 of beating the grass by lock dog 60 and spring 50 and can't directly be pulled out, avoided in the course of the work, the situation that the rope of beating the grass is thrown out of, the firmness height.

Using method of the present utility model is:

Lock dog 60 and spring 50 are arranged in the rope locating slot 302 of beating the grass of lower cover 30, strip hole 601 on the lock dog 60 is set on the reference column 70, lock dog 60 is positioned in the rope locating slot 302 of beating the grass by the elastic force of spring 50, rope 20 the band tooth limit of beating the grass contacted inward with lock dog 60 push away, at this moment, the rope 20 of beating the grass drives 60 power that generation pushes away inward of lock, lock dog 60 moves inward along strip hole 601, make spring 50 compress, thereby at lock dog 60 and beat the grass and produce the certain clearance rope 20 of will beating the grass between the rope locating slot 302 and be in place, after the rope 20 of beating the grass installs, under the elastic force effect of spring 50, lock dog 60 will beat the grass the rope 20 be stuck in tightly lower cover 30 beat the grass the rope locating slot 302 in, firmly pull outward and also the rope 20 of beating the grass can not pulled out, the rope 20 of beating the grass of the other end has just been finished the installation of the rope 20 of beating the grass after also installing, moving head is fixed on the mower and can uses by the moving head installing hole 303 on the lower cover 30.After the rope 20 of beating the grass is worn, the rope 20 of beating the grass that will expose pushes away toward wire hole 301 directions, at this moment, lock dog 60 also produces the power that pushes away inward, thereby compression spring 50, lock dog 60 and the gap of beating the grass between the rope locating slot 302 increase, and the rope 20 of beating the grass can be pulled out from the wire hole 301 on lower cover 30 frustums of a cone, then the new rope 20 of beating the grass is filled in the replacing of promptly having finished the rope of beating the grass after putting in place from entrance hole, just can continue to use.

When the utility model is beaten the grass rope in installation, replacing, need not to open the loam cake and the lower cover of moving head, install and change convenient, simple to operate, the moving head of this structure has been cancelled drum, and the rope of beating the grass need not to be wrapped in the drum, only needs certain-length to get final product, saved use cost greatly, be applicable on the various mowers.

The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
