Embodiment
Please refer to Fig. 1 to Fig. 4, a kind of mower 100, for cutting operation on lawn.Grass on lawn has polytype, and the height that various types of grass will maintain is different.From the cutting-height on the lawn of a type, to the cutting-height on the lawn of another kind of type, adjust the time longer, What is more cannot reach the scope needing due to the restriction of stroke.The invention provides a kind of mower 100 that can adapt in the scope work of different cutting-heights.This mower 100 comprises: be provided with the cutterhead 1 of blade installation portion 10, drive cutterhead 1 rotation motor 2, connect motor 2 and cutterhead 1 driving member 3, hold the fuselage of motor 2.Fuselage comprises the wheel 6 of frame 5, frames 5 and the casing 7 that covers frame 5.Please refer to Fig. 5 to Fig. 7, driving member 3 has the face that connects 31 connecting with cutterhead 1, cutterhead 1 have can with the first installed surface 11 and the second installed surface 12 that connect face 31 butts.The first installed surface 11 cutterhead matrix cutterhead matrix when connecting the distance of face 31 and the second installed surface 12 and connecting face 31 butt when connecting face 31 butt is different to the distance that connects face 31.By the first installed surface 11 with connect face 31 assemblings, or the second installed surface 12 with connect face 31 and assemble and can realize the different of cutting-height.Introduce respectively each parts of mower 100 below.
Cutterhead 1 is driven and is rotated and drive blade 4 operations that are mounted thereon by motor 2, is discoid pieces.The shape of cutterhead 1 is preferably circular.Circular cutterhead 1 is because of the even stability of rotation of its Mass Distribution.Certainly, also can be set to according to actual needs triangle, square etc.
Please refer to Fig. 5 to Fig. 7, cutterhead 1 have can with the first installed surface 11 and second installed surface 12 of the face that connects 31 butts of driving member 3.Between the first installed surface 11 and the second installed surface 12, there is spacing.Because existence first installed surface 11 of this spacing cutterhead matrix cutterhead matrix when connecting the distance of face 31 and the second installed surface 12 and connecting face 31 butt when connecting face 31 butt is different to the distance that connects face 31.
The first installed surface 11 and the second installed surface 12 can be positioned at the same side of cutterhead 1, also can be positioned at the both sides that cutterhead 1 is relative.
Introduce the situation that the first installed surface 11 and the second installed surface 12 are positioned at cutterhead 1 the same side below.Cutterhead 1 has a bottom surface.Cutterhead 1 also has from first erecting bed (not shown) of bottom surface differing heights and the second erecting bed (not shown).The end face of the first erecting bed is the first installed surface 11.The end face of the second erecting bed is the second installed surface 12.Because the position of blade installation portion 10 is fixed, so there is different cutting-heights when the face that connects 31 butt first installed surfaces 11 of driving member 3 and the second installed surface 12.
Highlight the embodiment that preferred the first installed surface 11 of the present invention and the second installed surface 12 are positioned at the both sides that cutterhead 1 is relative below.Cutterhead 1 is provided with some cutterhead installing holes 13 and connects the first installed surface 11 and the second installed surface 12.Thereby screw, bolt, rivet etc. can connect cutterhead 1 is fixed on driving member 3 with cutterhead installing hole 13.
Cutterhead 1 comprises cutterhead matrix 15 and protrudes from the middle part of cutterhead matrix 15 boss 14 arranging.
Please refer to Fig. 7 and Fig. 8, boss 14 is highly 8-15 millimeter.The height of this boss 14 mates with cutting-height is poor.Wherein a kind of matching way is that boss 14 height h are half of cutting-height poor (H1+H2).Such benefit is, survey tool that need not be extra can keep default cutting-height poor.The first installed surface 11 is the end face of the projected direction of boss 14, and the second installed surface 12 is the back side contrary with projected direction of boss 14.
The both sides of cutterhead matrix 15 are plane, such cutterhead matrix 15 and are not easy to occur long-pending grass, prevent accumulation grass dirt corrosion cutterhead 1 or driving member 3 between cutterhead 1 and driving member 3.On cutterhead matrix 15, be evenly arranged several blade installation portions 10 for blade 4 is installed.Cutterhead 1 both sides are respectively equipped with around the first convex tendon 16 of boss 14 and the second convex tendon 17, the first convex tendons 16 and the second convex tendon 17 all between boss 14 and blade installation portion 10.Which because a side of cutterhead 1 is provided with the first convex tendon 16 or second convex tendon 17 of ring-type, so no matter cutterhead 1 is installed from side, can well grass bits be kept off in the first convex tendon 16 of ring-type or the periphery of the second convex tendon 17.
Because boss 14 has certain height, thus the end face of boss 14 and the back side be mounted to driving member 3 connect face 31 time there is different cutting-heights.
Please refer to Fig. 5 to Fig. 8, mower 100 also comprises blade 4, and described blade 4 can rotate freely and be installed on blade installation portion 10.Blade installation portion 10 is provided with some blade installing holes 101.Thereby screw, bolt, pin or rivet and blade installing hole 101 connect blade 4 are positioned to blade installation portion 10.Blade installation portion 10 can be arranged on the same side of cutterhead 1 outstanding boss 14, also can be arranged on the opposition side of cutterhead 1 outstanding boss 14.Preferably, blade 4 is arranged on the below of cutterhead 1, and when the end face of boss 14 is mounted to driving member 3, blade 4 is arranged on the opposition side of cutterhead 1 outstanding boss 14; When the back side of boss 14 is mounted to driving member 3, blade 4 is arranged on the same side of cutterhead 1 outstanding boss 14.Blade 4 is provided with like this and is beneficial to cutting, prevents that grass from accumulating in blade 4 and causing blade 4 corrosion around.
More than introduced cutterhead 1 and be installed on the blade 4 on cutterhead 1, having introduced the driving member 3 of motor 2 and connection motor 2 and cutterhead 1 below.
Motor 2 is used to the rotation of cutterhead 1 that power is provided.Motor 2 has the motor shaft 21 for exporting.
Driving member 3 one end are connected with motor shaft 21, and the other end is connected with cutterhead 1.Driving member 3 has the face that connects 31 connecting with cutterhead 1.The area that connects face 31 is not more than the area of the first installed surface 11, and is not more than the area of the second installed surface 12, connects like this face 31 and the first installed surface 11 or the second installed surface 12 and connects can not interfere and cause being difficult to installing.Connect face 31 and be provided with some matching holes 311.Thereby screw, bolt, rivet etc. can coordinate cutterhead 1 is fixed on driving member 3 with cutterhead installing hole 13 and matching hole 311.
Frame 5 is for holding control system on motor 2 and other mowers 100, energy source etc., for all the other parts of mower 100 provide whole installation frame.Control system is for commanding the operation of mower 100.Control system comprises chip, the surface-mounted integrated circuit of chip etc. is installed.Control system is controlled motor 2 by circuit, and then controls the rotation of blade, the actions such as walking of wheel.Energy source is generally battery pack.
