Description of technical improvements of the hand-held rotary tiller.
Principle name
Description of improvement
Replacement of a mechanical system
The pressure sensor in the handle of the hand-held rotary tiller can detect the pressure of the operator's hands on the handle. When an accident occurs, the single chip microcomputer built in the hand-held rotary tiller will cut off the motor and stop the work.
Use of porous materials
Porous materials can be used for sound insulation, but also can reduce the quality and vibration of hand-held rotary tiller.
Composite materials
The composite material can be used to improve the strength and rigidity of the machine and reduce the quality of the hand-held rotary tiller.
Dynamicity
Hand-held connecting rod was adjustable. Rotary tiller blade can be replaced.
