Detailed description of the invention
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with attached
Detailed description of the invention of the present utility model is described in detail by figure.
Refer to hay mover 100 schematic diagram that Fig. 1 to Fig. 3, Fig. 1 are the present embodiment；Fig. 2 is shown in Fig. 1
The connection diagram of roller of hay mover；Fig. 3 is the signal processing circuit 122 of the hay mover shown in Fig. 1
Schematic diagram.
As it is shown in figure 1, a kind of hay mover 100, including fuselage 110 and sensor assembly 120, sensor die
Block 120 is arranged on fuselage 110.Also include roller 121, roller 121 near the bottom of fuselage 110, and
It is arranged at bottom or the periphery of fuselage 110.Sensor assembly 120 includes that at least one pops one's head in (not shown),
Probe is arranged on roller 121, is used for sensing meadow.
Above-mentioned hay mover 100, owing to probe is arranged on roller 121, if roller 121 contacts with meadow,
When hay mover is advanced, roller 121 rotates walking, and the friction between roller 121 and meadow is rolling friction,
The friction of probe and meadow can be reduced, thus reduce the running resistance of hay mover, reduce the power consumption of hay mover,
Improve mowing efficiency.
As it is shown in figure 1, hay mover 100 can also include at least one main road wheel 140, main road wheel 140
It is arranged at bottom fuselage 110.So, hay mover 100 can rely on main road wheel 140 free on meadow
Walking, is greatly reduced manual operation, it is possible to cut meadow quickly and easily.Hay mover 100 in the present embodiment
Including three main road wheels 140, so hay mover 100 smooth running can be made with balanced support hay mover 100.
In other embodiments, do not limit to and this.
Sensor assembly 120 can be capacitive humidity sensor, is used for sensing meadow situation.So, sensing
Device module 120 can sense the particular state on meadow according to the humidity condition on meadow, it is simple to hay mover 100
Perform cutting operation.
Wherein in an embodiment, roller 121 is double-decker, and including internal layer and outer layer, probe is arranged
On internal layer, outer layer is protective layer.So, in hay mover 100 traveling process, outside roller 121
Probe can be protected by protective layer, improves the service life of probe.Preferably, this internal layer is metal level,
This metal level is as probe so that sensing inductive effects is more preferable.
In another embodiment, this outer protective layer can also be made of plastics, and so can strengthen roller
Wearability, preferably protection setting probe on internal layer.
Roller 121 is hung on bottom fuselage 110.So can sense meadow more accurately.Roller 121
Quantity is one or more.The quantity of roller 121 can be arranged as required to, to improve induction efficiency.This
Embodiment includes that two rollers 121, two rollers 121 and main road wheel 140 are respectively positioned on the end of fuselage 110
Portion, the bottom of main road wheel 140 contacts with ground, and two rollers 121 hang on main road wheel 140 respectively
The front of direct of travel and/or rear, during i.e. shorter on meadow or ground even, the bottom of two rollers 121
Not in contact with the ground.During hay mover 100 is advanced or retreated, when meadow is higher or meadow is concavo-convex not
At ordinary times, roller 121 contacts with meadow, and roller 121 is advanced as auxiliary wheel or retreats, it is to avoid with meadow
Friction, reduces meadow and gives the resistance of hay mover 100, it is simple to hay mover 100 is advanced.
It should be noted that in other embodiments, the quantity of roller 121 is not limited to this, it is also possible to for
One or more.If roller 121 is set to one, while gratification answers meadow demand, can save again
Cost-saving.If roller 121 is set to multiple, such as three or four, can be uniformly distributed, increase is cut
Grass machine 100 senses the scope on meadow, effectively cuts meadow.
As in figure 2 it is shown, hay mover 100 also includes bearing 150 and connecting shaft 160, bearing 150 is arranged at machine
On body 110, the central axis of bearing 150 is bottom fuselage 110.One end of connecting shaft 160 and bearing
150 are connected, and the other end is connected with roller 121, and roller 121 can be around bearing 150 together with connecting shaft 160
Central axis.So, when roller 121 any one angle of traveling process run into higher meadow or
Person's barrier, can be freely rotatable around the central shaft of bearing 150, while sensing meadow, also may be used
To get around meadow or barrier, reduction meadow or barrier give the resistance of roller 121, and then reduce mowing
The running resistance of machine 100, improves mowing efficiency.In the present embodiment, connecting shaft 160 is bending, connects
The two ends line of axle 160 and the central shaft of bearing 150 are the angle of preset in advance.So, roller 121 around
The slewing area of the central shaft bearing 150 is relatively big, can get around bigger barrier, preferably auxiliary cutting
Grass machine 100 is advanced.
Being additionally provided with line channel (not shown) in connecting shaft 160, wire 170 is through line channel, by roller
121 are connected with control module 130, so can realize the signal between roller 121 and control module 130 and pass
Defeated, it is simple to hay mover 100 is mowed automatically.
In other embodiments, roller 121 can be universal wheel.Universal wheel inherently can with meadow
In parallel plane freely rotatable, so, universal wheel runs into meadow in any one angle of traveling process,
It is positioned at the probe on roller 121 and can identify meadow, improve mowing efficiency.If or run into barrier,
Roller 121 can get around barrier neatly, reduces barrier and gives the resistance of roller 121, and then reduces
The running resistance of hay mover 100.
Hay mover 100 also includes that control module 130, control module 130 are arranged on fuselage 110, such as Fig. 3
Shown in, sensor assembly 120 also includes signal processing circuit 122, the input of signal processing circuit 122 with
Probe electrical connection, the outfan of signal processing circuit 122 electrically connects with the input of control module 130.Pass
Sensor module 120 is capacitance sensor (not shown), a pole piece as this capacitance sensor of popping one's head in, ground
The ground of table or signal processing circuit 122 is as the reference pole piece of capacitance sensor.By detection probe and earth's surface
Between the change of electric capacity, to judge the situation on meadow.Signal processing circuit 122 passes according to capacitance sensor
Defeated signal, is output as square wave.When probe senses meadow, between probe and earth's surface, dielectric constant becomes big,
Electric capacity between probe and earth's surface increases, and the square wave frequency of signal processing circuit 122 output then reduces.When not having
When having grass, the dielectric constant between probe and earth's surface then diminishes, and the electric capacity between probe and earth's surface also reduces,
The square wave frequency of signal processing circuit 122 output increases.Thus control module 130 can be according to signal processing
The square wave frequency of the output of circuit 122, to judge meadow situation, controls the duty mowed..
It should be noted that in other embodiments, the position of signal processing circuit 122 is not limited to passing
In sensor module 120, it is also possible to be contained in control module 130.Additionally, signal processing circuit 122
Signal intensity does not limits to and this, when roller 121 senses meadow, and the output letter of signal processing circuit 122
Number can also change for level, as long as can be shown that roller 121 senses meadow.
Specifically, signal processing circuit 122 includes Schmidt trigger ST, and Schmidt trigger ST's is defeated
Enter end and connect roller 121, the input of the outfan link control module 130 of Schmidt trigger ST.When
Roller 121 senses meadow, the output signal change of Schmidt trigger ST, it is achieved hay mover 100 is automatic
Identify meadow.Further, signal processing circuit also includes electric capacity C and resistance R.Electric capacity C one end is even
Connect the input of Schmidt trigger ST, other end ground connection.The two ends of resistance R are connected in schmidt trigger
Between input and the outfan of device ST.There is grass below roller 121 or contact with grass, it will causing electric capacity
The change of C, thus cause Schmidt trigger ST output signal to change, it is achieved meadow is detected, it is simple to effectively
Cutting meadow.
