Embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
Mower as Figure 1-3, comprise casing 1, guard shield 2, Handleset 3 and rotary head assembly 4, described Handleset 3 is fixedly connected with rotary head assembly 4, and described rotary head assembly 4, guard shield 2 are flexibly connected with casing 1, when rotary head assembly rotates, guard shield 2 is followed rotation simultaneously.And rotary head assembly 4 has the first axle 41, described guard shield 2 has the second axle 21, and when rotary head assembly 4 rotates along the first axle 41, guard shield 2 rotates along the second axle 21 simultaneously.Wherein, on rotary head assembly 4, be provided with locking device, described rotary head assembly 4 is fixed by locking device with casing 1.By an action, realize rotary head assembly 4 and rotate with guard shield 2 simultaneously, and realize beat the grass and two states of deburring between conversion, and still meet the requirement of mower security regulations after guard shield 2 rotations.Mower also comprises moving head and the motor that drives moving head, and motor is positioned at casing 1.
Wherein, follow rotary head assembly 4 synchronously rotate for ease of guard shield 2, be provided with the first gear 42 on described rotary head assembly 4, be provided with the second gear 22 on described guard shield 2, described the first gear is with 42 second gear 22 is meshing is connected.And in order more smoothly the driving torque of runner assembly 4 to be passed to guard shield 2, between described the first gear 42 and the second gear 22, be equipped with duplicate gear 5, this duplicate gear 5 is flexibly connected with casing 1, the input of described duplicate gear 5 and the first gear 42 are meshing, and the output of described duplicate gear 5 and the second gear 22 are meshing.
As in Figure 2-4, for ease of casing 1 and rotary head assembly 4, by locking device, lock in time and release, locking device comprises toggle 6, this toggle 6 rotates or is slidably connected with rotary head assembly 4, between described toggle 6 and rotary head assembly 4, be provided with elastic component 7, preferred elastomeric part of the present invention is spring or torsion spring.On described toggle 6, be provided with projection 61, on described casing 1, be provided with and projection 61 corresponding some grooves 11.Its further groove 11 is uniformly distributed on the circumference of casing 1, on the preferred casing 1 of the present invention, is at least distributed with 4 grooves 11.Stir toggle 6, when projection is 61 away from groove 11, until while throwing off completely with groove 11, casing 1 can rotate relatively with rotary head assembly 4, i.e. release; Unclamp toggle 6, toggle 6 is due to the restoring force effect of elastic component 7, protruding 61 rollbacks, and locking device resets, and when projection 61 snaps in groove 11, casing 1 is relative with rotary head assembly 4 fixing, locks.
For improving transmission efficiency, described the first axle 41 vertical with the second axle 21 arranges, and this setting can must be passed to guard shield 2 fast by the moment of torsion of rotary head assembly 4 is timely.And the gearratio between the first gear 42 and duplicate gear 5, duplicate gear 5 and the second gear 22 is 1: 1.
In addition, for ease of the steadiness of manufacture and structure, preferred the first described gear 42 of the present invention is wholely set with rotary head assembly 4, and described the second gear 22 is wholely set with guard shield 2.
Wherein, for ease of mower, beat the grass or deburring, relative casing 1 angle rotatable of described guard shield 2 is 0-180 °, and relative casing 1 rotational angle of the preferred guard shield 2 of the present invention is 0-90 °.
The course of work of the present invention is as follows:
When mower proceeds to deburring state by the state of beating the grass, first stir toggle 6, projection 61 on toggle 6 away from groove 11 until throw off with groove 11, realized rotary head assembly 4 release relative to casing 1, then, drive rotary head assembly 4 to clockwise rotate, the first gear 42 on rotary head assembly 4 drives the input of duplicate gear 5 to rotate, the output of duplicate gear 5 drives the second gear 22 to rotate, guard shield 2 is followed the second gear 22 and is synchronously rotated, guard shield 2 rotates counterclockwise after 90 °, has realized guard shield 2 and has rotated with rotary head assembly 4 simultaneously; Unclamp toggle 6, toggle 6 is due to the effect of elastic component 7 restoring forces, and the projection 61 on toggle 6 snaps in groove 11, realizes rotary head assembly 4 locking relative to casing 1, and mower enters deburring state, as shown in Figure 6.
At mower, by deburring state, entered while beating the grass state, first stir toggle 6, projection 61 on toggle 6 away from groove 11 until throw off with groove 11, realized rotary head assembly 4 release relative to casing 1, then, drive rotary head assembly 4 to rotate counterclockwise, the first gear 42 on rotary head assembly 4 drives the input of duplicate gear 5 to rotate, the output of duplicate gear 5 drives the second gear 22 to rotate, guard shield 2 is followed the second gear 22 and is synchronously rotated, guard shield 2 clockwise rotates after 90 °, has realized guard shield 2 and has rotated with rotary head assembly 4 simultaneously; Unclamp toggle 6, toggle 6 is due to the effect of elastic component 7 restoring forces, and the projection 61 on toggle 6 snaps in groove 11, realizes rotary head assembly 4 locking relative to casing 1, and mower enters the state of beating the grass, as shown in Figure 5.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
