Description
Technical field
This utility model relates to technical field of garden, particularly relates to a kind of shockproof grass-mowing machine head.
Background technology
Grass-mowing machine is the hand-held tool of weeds local for cutting lawns, garden, pasture etc..
The head of the grass-mowing machine of prior art mainly includes electric machine casing 1, lower bearing 2, rotor 3, upper bearing (metal)
4, stator 5 and motor cover 6, stator 5 and electric machine casing 1 close-fitting, upper bearing (metal) 4 and motor cover 6 close-fitting, lower bearing 2 and motor casing
Body 1 close-fitting, rotor 3 is positioned in the middle of stator 5, and rotor 3 two ends are connected with upper bearing (metal) 4 and lower bearing 2 respectively, and motor cover 6 is passed through
Screw is connected with electric machine casing 1, and rotor 3 is for connecting the work package of grass-mowing machine.
Because during grass-mowing machine work, grass-mowing machine head can produce vibrations because of work package, and these vibrations can pass successively
Passing lower bearing 2, electric machine casing 1 and upper bearing (metal) 4, and more transmit backward, shaking the biggest, so result at upper bearing (metal) 4
Vibrations dynamics more much larger than the vibrations dynamics at lower bearing 2, and the handle installation portion 7 of prior art is and electric machine casing
1 is integrated, and handle installation portion 7 is also connected with motor cover 6, which results in handle installation portion 7 and can produce bigger
Vibrations so that the operation handle being arranged on handle installation portion 7 also can produce significant shock, thus brings very to operator
Discomfort.
Utility model content
Technical problem to be solved in the utility model is: provides a kind of and can preferably reduce the anti-of operation handle vibrations
Shake grass machine head.
This utility model be the technical scheme is that a kind of shockproof grass-mowing machine head, pacifies including electric machine assembly and handle
Dress portion, wherein, this grass-mowing machine head also includes that shockproof housing, handle installation portion are arranged on shockproof housing, shockproof lower housing portion
Being connected with electric machine assembly bottom, shockproof housing other position in addition to link position contacts with electric machine assembly does not connects with electric machine assembly
Touch.
Using above structure compared with prior art, this utility model has the advantage that due in this utility model
Handle installation portion is not set directly on electric machine casing, and the shockproof housing newly increased is except its underpart and electric machine assembly bottom
Connecting outside contact, other position all contacts less than with electric machine assembly, and therefore, shockproof housing is the most a small amount of by electric machine assembly bottom
The impact of vibration, so, the vibration sense of the handle installation portion being arranged on shockproof housing is also greatly reduced, thus finally makes installation
Operation handle on handle installation portion is almost without vibratory sensation.
As preferably, electric machine assembly includes electric machine casing, lower bearing, rotor, upper bearing (metal), stator and motor cover, stator
With electric machine casing close-fitting, upper bearing (metal) and motor cover close-fitting, lower bearing and electric machine casing close-fitting, rotor is positioned in the middle of stator, and turns
Sub-two ends are connected with upper bearing (metal) and lower bearing respectively, and motor cover is connected with electric machine casing, the lower surface of shockproof housing and motor casing
Body bottom connects, and is equipped with gap between shockproof housing and motor cover and between shockproof housing and electric machine casing.At shockproof shell
The purpose between body and electric machine casing and being respectively provided with gap between shockproof housing and motor cover is, it is ensured that only shockproof shell
The lower surface of body has with electric machine casing and contacts, and other positions of shockproof housing cavity do not connect with electric machine casing and motor cover
Touching, the most only shock energy on lower bearing is delivered on shockproof housing, and then is delivered on handle installation portion, and such handle is installed
The vibrations received in portion are less.
As preferably, handle installation portion is one-body molded with shockproof housing.It is higher, no that handle installation portion firmness is so set
Easily come off from shockproof housing.

Detailed description of the invention
With detailed description of the invention, this utility model is described further below in conjunction with accompanying drawing, but this utility model is not only
It is limited to detailed description below.
Group of motors as shown in Figure 2 and Figure 3, same as the prior art, in this utility model shockproof grass-mowing machine head
Part also includes also electric machine casing 1, lower bearing 2, rotor 3, upper bearing (metal) 4, stator 5 and motor cover 6, and stator 5 is tight with electric machine casing 1
Joining, upper bearing (metal) 4 and motor cover 6 close-fitting, lower bearing 2 and electric machine casing 1 close-fitting, rotor 3 is positioned in the middle of stator 5, and rotor 3 two ends
Being connected with upper bearing (metal) 4 and lower bearing 2 respectively, motor cover 6 is connected with electric machine casing 1 by screw, and rotor 3 is used for connecting grass-mowing machine
Work package.
Unlike the prior art, this utility model also includes shockproof housing 8, and handle installation portion 7 is arranged on shockproof shell
On body 8 and one-body molded with shockproof housing 8.Shockproof housing 8 is whole to be set on electric machine casing 1, and the lower surface of shockproof housing 8
With electric machine casing 1 lower contacts, and both are connected by screw fixing, and other positions of shockproof housing 8 inwall and electric machine casing 1
And between motor cover 6, be respectively provided with certain interval, thus ensure shockproof housing 8 other portion in addition to link position contacts with electric machine assembly
Position does not contacts with electric machine assembly.
From a structural point, shockproof housing 8 only lower surface contacts with electric machine casing 1, and the interior intracavity of shockproof housing 8
Wall does not all have to contact with electric machine casing 1 or motor cover 6, thus makes shockproof housing 8 be transmitted through by from lower bearing 2
Sub-fraction vibrations so that the vibrations that shockproof housing 8 is subject to are less, and then make and the shockproof integrated handle of housing 8
The vibrations of installation portion 7 are the least.
