Description

Rear gear shifting operating mechanism for mini-tiller

Technical Field

The utility model relates to a gear shifting operating mechanism, in particular to a rear gear shifting operating mechanism for a mini-tiller.

Background

At present, on the existing mini-tiller, a gear shifting lever is generally designed into a rear gear form for the convenience of operation of an operator, although the mode is feasible, the gear shifting operation of the rear gear form is difficult due to the limitation of structural design, so that the operation of the operator is inconvenient, and the phenomenon of gear shifting failure during gear shifting also exists.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a mini tiller rear gear shift operating mechanism with easy operation.

The utility model aims at realizing through such technical scheme, a little for cultivator back gear shift operating device, including being located the riser combination on the transmission box be provided with the hand (hold) pipe subassembly on the riser combination the below of hand (hold) pipe subassembly one side is provided with shift operating device, shift operating device's front end is connected with the shift arm that sets up on the transmission box, shift operating device's rear portion and hand (hold) pipe subassembly swing joint.

The gear shifting operating mechanism comprises a first swing pair, a second swing pair and a third swing pair which are connected in sequence, the middle of the first swing pair is connected with the handle pipe assembly, and the front end of the third swing pair is connected with the gear shifting arm.

The handle pipe assembly comprises a handle pipe, a handle pipe protective cover is arranged on the handle pipe, a U-shaped groove plate is arranged on the lower end face of the handle pipe protective cover, a pin shaft is arranged in the U-shaped groove plate, and the rear portion of the gear shifting operating mechanism is movably connected with the pin shaft.

Further, the shift operating mechanism includes a shift operating lever and a shift lever, the shift operating lever is V-shaped, a front end of the shift operating lever is movably connected with a rear end of the shift lever, and a front end of the shift lever is connected with the shift arm; the rotation center of the gear shifting operating rod is arranged on the pin shaft; the front end of the gear shifting operating rod and the rear end of the gear shifting rod form a second swing pair, and the front end of the gear shifting rod and the gear shifting arm form a third swing pair.

Since the technical scheme is used, the utility model has the advantages of simple structure, convenient operation, reliability are high, adopt the operator that it can make light press or stimulate the gear shifting pole to shift gears, operate light portably more, simultaneously, still prevented the emergence of the not in place phenomenon of shifting gears.
