Abstract
The invention discloses a grass mower which comprises a longitudinally-extending main body, a handheld portion, a motor, an output shaft, a first saw blade, a second saw blade, a first transmission system and a second transmission system. The handheld portion is arranged at one end of the main body, a spindle is arranged at the other end of the main body, the output shaft defines an axis, the first saw blade and the second saw blade are mounted around the axis of the output shaft respectively, and the first transmission system and the second transmission system are driven by the spindle respectively. The first transmission system drives the first saw blade to rotate around the axis of the output shaft along a first direction, and the second transmission system drives the second saw blade to rotate around the axis of the output shaft in a second direction opposite to the first direction. Grass cutting is realized by utilizing the first saw blade and the second saw blade which rotate relatively, cut faces of grass are enabled to be orderly and complete, and cutting quality of the grass is guaranteed; after the first saw blade and the second saw blade go through the first transmission system and the second transmission system, rotating speed of the first saw blade and the second saw blade can be reduced, so that obstacles like stone in the grass can be prevented from being hit away during work, and safety of a user is guaranteed.

Embodiment
Present embodiment discloses a kind of mower, can realize in work and can not beat the small-scale obstacle things such as slungshot, and user is safer, and guarantees that careless section is neatly without tear trace, thereby guarantees cut quality.It is contemplated that: mower comprises that the main body extending longitudinally, the Handheld Division that is arranged at main body one end and the other end have main shaft, are installed on described main body and have the output shaft of axis, the first saw blade of installing around output shaft axis respectively and the second saw blade and respectively by the first power train and second power train of main shaft drives for the motor of drive shaft, definition; The first power train drives the first saw blade to be rotated in a first direction around output shaft axis, and the second power train drives the second saw blade to rotate along the second direction contrary with first direction around output shaft axis.Utilize in relative rotation the first saw blade and the second saw blade to realize and cut grass, make careless cut surface neatly complete, guarantee careless cut quality; After the first power train and the second power train, the rotating speed of the first saw blade and the second saw blade can reduce, and therefore in work, the barriers such as stone in thick grass can not beaten and is flown, and user is safer.In addition, the rotating speed of the first saw blade and described the second saw blade is different and abut against together, can better cut grass.
Utilize above-mentioned design, present embodiment discloses the specific embodiment of two kinds of mowers, certainly, is originally not limited to this.
Please refer to the drawing 1 and Fig. 2, the first embodiment of present embodiment mower 100.
Mower 100 comprises the first saw blade 160 and the second saw blade 170 and the first power train being driven by main shaft 130 respectively and the second power train that the main body 110 extending longitudinally, the Handheld Division 120 that is arranged at main body 110 one end and the other end have main shaft 130, are installed on main body 110 and have the output shaft 150 of axis X, install around output shaft axis X respectively for the motor 140 of drive shaft 130, definition.The first power train drives the first saw blade 160 to be rotated in a first direction around output shaft axis X, and the second power train drives the second saw blade 170 to rotate along the second direction contrary with first direction around output shaft axis X.
Further, the first power train comprises the master gear 132 being arranged on main shaft 130 and the first output gear 152 being meshed with master gear 132.The second power train comprises master gear 132 and the second output gear 154 being meshed with master gear 132.The first output gear 152 drives the first saw blade 160 to rotate, and the second output gear 154 drives the second saw blade 170 to rotate.The first output gear 152 is different from the tip diameter of the second output gear 154, and master gear 132 is bevel gear.
The first output gear 152 is fixed on output shaft 150, and mower 100 also comprises the sleeve 156 being sheathed on output shaft 150 and the bearing 158 that is installed on sleeve 156.The second output gear 154 is fixed on sleeve 156, the first saw blades 160 and is fixed on output shaft 150, the second saw blades 160 and is fixed on sleeve 156.In the direction of extending in output shaft axis X, the second saw blade 170 and the second output gear 154, between the first saw blade 160 and the first output gear 152, are realized the coaxial direction of the first saw blade 160 and the second saw blade 170 and are rotated.
Motor 140 drive shaft 130 are rotated, and main shaft 130 drives master gear 132 to rotate, and master gear 132 drives with the first output gear 152 and second output gear 154 of its engagement and rotates.Again because master gear 132 is bevel gear, the first output gear 152 is different from the tip diameter of the second output gear 154, make the first output gear 152 and the second output gear 154 around output shaft axis X relatively rotate and rotating speed different, and then make the first saw blade 160 and the second saw blade 170 around output shaft axis X relatively rotate and rotating speed different.Rotating speed by the first saw blade 160 and the second saw blade 170 after the transmission of the first power train and the second power train can reduce, and then has guaranteed high-quality and the high security of cutting.The rotating speed of the first saw blade 160 and the second saw blade 170 is different and abut against together, can better cut grass.
The Handheld Division 120 of mower 100 is also provided with the first switch 122 and second switch 124, during work, need trigger the first switch 122 and second switch 124 ability starters 140 simultaneously.Mower 100 also comprises the guard shield (not shown) that is positioned at the first saw blade 160 and the second saw blade 170 peripheries, guarantees user's safety.Mower 100 also comprises and is installed on output shaft 150 for fixing the securing member 159 of the first saw blade 160 and the second saw blade 170.
Please refer to the drawing 3 is to Fig. 7, the second embodiment of present embodiment mower 200.
