THROTTLE SAFE CONTROL APPARATUS OF SMALL GASOLINE DIGGING MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/101262
Kind Code:
A1
Abstract:
A throttle safe control apparatus of a small gasoline digging machine comprises an operation frame (1). Handles are respectively arranged on two opposite sides of the operation frame (1). A throttle operation handle (2) is on a right side, and an operation frame balancing handle (3) is on a left side. A throttle control apparatus (4) is fixedly arranged above the operation frame (1). The throttle control apparatus (4) is connected to a gasoline engine installed in a middle position of the operation frame (1) through a throttle cable (6). A touch rod (7) is arranged on one side of the throttle control apparatus (4). The throttle operation handle (2) is connected to the throttle control apparatus (4) through the throttle cable (6). When the digging machine works, if a rotating drill encounters a tree root or a rock and stops rotating, a body of an operator touches the touch rod (7) and makes the touch rod rotate to adjust the throttle control apparatus (4), reducing oil supply of the gasoline engine, decreasing a rotational speed of the gasoline engine, and avoiding a danger generated due to an overlarge torque. The throttle safe control apparatus is reasonable in design, safe to operate, simple and convenient, and highly practical.
