The backpack brush saw
Technical field
The utility model relates to gardens equipment for plant protection technical field, particularly relates to a kind of brush saw.
Background technology
Backpack brush saw of the prior art is made up of frame, gasoline engine and working beam, and this brush saw rubber oil hose is exposed, the unprotect device, fragile, have a potential safety hazard; Be connected through hard axle between the frame of this machine and the working beam, can't realize full angle work; Connected mode is quartet connection between this machine gear-box and the working beam, poor stability, and vibrations are big; This machine carrying handle does not have damping device, and when operation, comfort is poor; It is rubber shock-absorbing that this machine is born the frame damping modes, and damping effect is poor.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, a kind of handling safety, good damping effect is provided, can realizes the backpack brush saw of full angle work.
The utility model is made up of frame, gasoline engine and working beam, is connected through flexible axle between said working beam and the frame; The terminal gear-box of said working beam is connected with working beam through spline.
Be provided with a spiral steel wire protection device in the oil pipe outside of said gasoline engine; Be provided with spring vibration damper on the frame bearing of said frame; On the carrying handle of said working beam, be provided with Rubber shock-absorbing pad.
The utility model is owing to adopt above structure, compares with prior art to have handling safety, good damping effect, can realize the advantage of full angle work.
