The invention relates to caterpillar tractors, in particular to a gear shifting operation mechanism of a caterpillar tractor. The gear shifting operation mechanism comprises a base assembly, an operation mechanism body, a rotary mechanism and a guide mechanism. The operation mechanism body comprises an operation handle, an operation rod, a pull rod and an operation rod base. A pull arm and a U-shaped connecting piece are arranged between the operation rod and the pull rod. The rotary mechanism comprises an upright and an L-shaped rotary arm. A middle rotary shaft is arranged on the lower side of the middle corner of the L-shaped rotary arm and fixed to the upright through a deep groove ball bearing. The guide mechanism comprises a guide groove and a clamp. The two ends of the L-shaped rotary arm are connected with the pull rod and the guide groove. The gear shifting operation mechanism is simple in structure, safe, reliable, flexible in gear shifting and capable of being operated in a labor-saving manner, a gearbox gear shifting shaft moves leftwards and rightwards on a tractor body through forward and backward movement of the operation rod on the tractor body, and therefore gearbox gears are switched.
Description
technical field [0001] The invention relates to a crawler rotary cultivator, in particular to a crawler tractor shift control mechanism. technical background [0002] Crawler tractors are one of the important machines in agricultural production. The gear shifting mechanism of crawler tractors mainly adjusts the position of the gear shaft of the gear box of the crawler tractor by manually controlling the shift lever, so as to realize the shifting of gears of the crawler tractor. Due to structural limitations, the prior art crawler tractor gearshift control mechanism has the disadvantages of complex structure, loose layout, high manufacturing and maintenance costs, inconvenient operation, and high failure rate. Contents of the invention [0003] The object of the present invention is to provide a crawler tractor gear shifting mechanism with simple structure, safety and reliability, flexible shifting, labor-saving operation, economy and durability. [0004] In order to achie...
