Grass-mowing machine further includes damping unit 240, specifically, damping unit 240 includes friction member 230.230 energy of friction member Along direction, 230a is moved.When friction member 230 is moved to the position contacted with shell 250, friction member 230 is because contact friction makes There is shell 250 trend rotated relative to spool 260 so that spool 260 and shell 250 is generated relatively with the increase of frictional force To make grass-mowing machine tool, there are one automatic winding patterns for rotation.Motor 220 drives at least one of spool 260 and shell 250 So that spool 260 and shell 250, which relatively rotate to beat the grass to restrict, is automatically wound to spool 260.Specifically, in motor Under 220 driving and under the action of friction member 230, spool 260 and shell 250 produce relative rotation and twine line automatically to realize Around to spool 260.Friction member 230 does not prevent completely the rotation of shell 250, only makes the rotating speed of shell 250 slack-off, to Realize the relative rotation of spool 260 and shell 250.

Certainly, enough ropes and when exposing the part of shell 250 and being not enough to cutting vegetation of beating the grass are wound in spool 260, So that spool 260 and shell 250 is produced relative rotation and can also be used to realize automatic unwrapping wire.

In the present solution, the effect of friction member 230 is to generate damping action to shell 250 to make the rotation of shell 250 Slow down, to generate the relative rotation with spool 260.User can be realized by direct or indirect actuating friction part 230 and be cut The cut mode and automatic winding pattern of careless machine, certainly, user can be in the corresponding states of required pattern by friction member 230 before this Then starting motor 220.

As shown in Figure 41 and Figure 42, as an implementation, moving head 310 includes spool 350 and shell 320.Shell 320 include upper shell 320a and lower housing 320b.

Compared with the damping unit 240 in Figure 39 and Figure 40, damping unit 340 includes a stop part in Figure 41 and Figure 42 330, stop part 330 is used to prevent the rotation of shell 320.Shell 320 is formed with the backstop slot 320c coordinated with stop part 330. Specifically, backstop slot 320c is set to upper shell 320a.In automatic winding pattern, the insertion of stop part 330 and backstop slot 320c coordinates, and shell 320 is made thoroughly to be prevented relative to the rotation of entire grass-mowing machine.Equally realize 320 phase of spool 350 and shell It will beat the grass on rope automatic winding to spool 350 to rotating to realize.Realize the function of automatic winding.

The effect of stop part 330 lies also in the rotation of damping shell 320, and difference lies in the damping action of friction member 230 is Slow down movement tendency, and the damping action of stop part 330 is then limiting displacement, will slow down movement tendency and limiting displacement and defines For damping；Friction member 230 and stop part 330 may be considered a kind of damping unit 340.

In Figure 43, shows a kind of motor shaft 460a drive shells 420 of motor 460 and unilateral bearing 440 is used to damp The scheme of spool 430.

As shown in figure 43, moving head 410 includes spool 430 and shell 420.Electric machine casing 450 accommodates motor 460, unidirectionally The setting of bearing 440 makes spool 430 be only capable of one-directionally rotating with respect to electric machine casing 450 between spool 430 and electric machine casing 450.Tool For body, electric machine casing 450 is formed with boss portion.The inner ring of unilateral bearing 440 is socketed in the periphery of boss portion.Unilateral bearing 440 inner ring is fixedly connected with the composition of electric machine casing 450.The outer ring of unilateral bearing 440 is only capable of relative to electric machine casing 450 to one A direction rotation.Rotation of the outer ring of unilateral bearing 440 relative to electric machine casing 450 to other direction is prevented from.430 sets of spool It is connected on the periphery of unilateral bearing 440.Unilateral bearing 440 makes spool 430 be only capable of turning to a direction relative to electric machine casing 450 It is dynamic.

Motor shaft 460a passes through spool 430 but does not directly drive spool 430, i.e., is not transmitted directly between spool 430 Torque；Motor shaft 460a rotation stops are connected to shell 420 and directly drive shell 420.

According to aforementioned introduced scheme and principle it is found that if motor 460 when rotating forward, spool 430 and shell 420 can rotate synchronously to execute cut mode, then when motor 460 is when rotating backward, 430 remains stationary of spool.Spool 430 and shell 420 can relatively rotate to execute automatic winding pattern.

It is appreciated that damping unit can not only damp shell the resistance of its rotation, spool can also be applied and be damped Its resistance rotated.

As another embodiment, damping unit can apply damping action to spool and shell.Specifically, resistance Buddhist nun's device may include the first damping piece and the second damping piece.First damping piece applies the first dynamic resistance of damping wire shaft rotation to spool Power.Second damping piece applies shell the second resistance of damping housing into rotation.Since the effect of the first resistance and the second resistance makes Obtaining shell and spool can relatively rotate.
