Into cutting zone, foreign matter can be effectively stopped again.Further, distance sensing device is provided with guard rail 70, when anti-
When guardrail is swung more than predetermined angle, control module shuts down grass-removing robot.
Reference picture 14 simultaneously coordinates shown in 10, and another structure type of the guard rail of the utility model grass-removing robot is prevented
Guardrail 70a is divided into epimere 71 and hypomere 72 by upper segment frames and lower frame, and epimere 71 is cut with scissors by the 4th axle 711 and chassis 12
Connect, hypomere 72 is hinged by the 5th axle 712 and epimere 71, epimere 71 is provided with distance sensing device 90, hypomere 72 is provided with and most put on
Dynamic angle.Shutdown is not triggered when hypomere 72 is in the slight oscillatory in the presence of the grass trimmed;When guard rail 70a touch it is dynamic
During the object of thing, people or other influences machine normal work, the amplitude of fluctuation of hypomere 72 exceedes in its default swing angle, drive
Section 71 is swung, and then triggers distance sensing device, and automatic control system makes shutdown.The setting of distance sensing device causes hay mover
Device people ensures not accidentally injure when traditional defense structure is broken.Front wing safeguard structure can effectively prevent grass using being hinged
Tangle, knot, also can effectively break away from the obstacles such as stone, ground out-of-flatness.
Specifically, distance sensing device includes switch and trigger member.Wherein, switch be arranged on chassis 12, switch touch
Point is corresponding with guard rail 70a epimere 71, and trigger member is arranged between the contact of switch and guard rail 70a epimere 71, touches
One end of outbox is connected with the contact switched or guard rail 70a epimere 71.Further, trigger member is configured to spring, can
Protection switch is not damaged by impulsive force.Certainly, distance sensing device can also from proximity switch or other can be by apart from change
Change be converted into automatic control system can process signal device.
As shown in figure 15, be the utility model grass-removing robot protection mechanism the 4th embodiment, in the present embodiment,
