Abstract
The utility model discloses a manual turning gear device of a tractor machine. A turning gear handle is operated during turning to enable a second transmission wheel to rotate towards one direction, and a first transmission wheel drives a turning gear rotating shaft to rotate towards the corresponding direction through transmission of a transmission chain, a ratchet wheel and the tractor machine rotate, and a pawl slips the back of teeth of the ratchet wheel. When a brake is released during turning, the pawl is clamped stably in a tooth groove of the ratchet wheel depending on an elastic restoring force of an elastic piece to enable the ratchet wheel and the tractor machine to stop rotating, prevent the tractor machine from reversing, and avoid heavy damage caused by reversing. When the brake is released during turning or a breakdown occurs (such as a turning gear transmission chain fractures), the ratchet wheel and the pawl are matched with each other to enable the tractor machine to achieve the goal of stopping rotating and preventing reversing without continuous pressure of a person during turning. In addition, the second transmission wheel (or turning gear hand wheel) used for turning gear is located on the left side or the right side of the tractor machine, and therefore the problem that front and back space is not enough when the second transmission wheel is placed in the front or at the back of the tractor machine is avoided.
