Mounting structure of clutch handle mechanism and grab bar for farming machine

Abstract

The invention discloses a mounting structure of a clutch handle mechanism and a grab bar for a farming machine. The clutch handle mechanism comprises a handle, a clutch stay wire, a mounting seat, a stay wire fixing pin and a mounting bracket, wherein the mounting seat adopts an aluminium rectangular box body structure; the stay wire fixing pin penetrates through a strip-shaped groove and then is prevented from falling off through a cotter pin inserted into the tail part of the stay wire fixing pin; the tail end of the clutch stay wire penetrates through the front wall of the mounting seat, stretches into the inner cavity of the mounting seat, and is fixed in the notch of the stay wire fixing pin through an anti-pulling-falling round head arranged at the tail end of the clutch stay wire; the mounting bracket is formed by downwards bending the left end and the right end of a steel plate, is integrally door-shaped and covers the tail part of the mounting seat; the two side walls of the mounting bracket are positioned in corresponding notch grooves; the lower end of the mounting bracket is hinged to the mounting seat; the front end of the handle is hinged to the stay wire fixing pin; the middle part of the handle is hinged to the upper end of the mounting bracket; the bottom of the mounting seat arches upwards to form an isosceles trapezoid cavity for accommodating the grab bar. The mounting structure is simple in structure, rapid in mounting, long in service life and high in reliability.

Description

technical field [0001] The invention relates to the technical field of farming machines, in particular to an installation structure of a clutch handle mechanism and a handrail on a miniature farming machine. Background technique [0002] The micro-farming machine uses an internal combustion engine as power, and a handle mechanism is installed on the armrest. The handle mechanism is connected to the clutch arm of the clutch through the clutch cable. The clutch arm and the clutch lever of the clutch are hinged to form a lever through a pin shaft. The friction plates inside the clutch close or disengage, thereby transmitting power or interrupting power transmission. When the clutch is closed, power is transmitted to the cultivator through the clutch, so that the cultivator rotates to cultivate the land; when the clutch is disengaged, the power transmission is interrupted, and the shift device additionally provided on the farm machine can be manipulated to shift gears, such as s...
