Independent gear shifting mini-tiller

Abstract

The invention belongs to the technical field of agricultural machinery, and relates to an independent gear shifting mini-tiller. The independent gear shifting mini-tiller comprises a gear shifting mechanism, a power component, wheels, a gearbox, and a handrail frame; the gear shifting mechanism comprises a handrail base fixed to a mini-tiller body and used for arranging the handrail frame, a gear shifting pull rod with one end connected with a gearbox gear shifting arm, and a telescopic gear shifting rod arranged on the handrail base and connected with the other end of the gear shifting pull rod; the telescopic gear shifting rod is composed of a main rod, a rotary drum, a pin, a spring, an auxiliary rod, and a check block; the main rod is rotatably connected with the armrest base through a rotating drum arranged on the main rod; the main rod is further slidably connected with the auxiliary rod through the pin arranged on the main rod; the spring is arranged between the main rod and the auxiliary rod; a sliding groove in sliding fit with the pin is formed in the auxiliary rod; the armrest base is provided with a stopping plate which abuts against the check block arranged on the auxiliary rod; and the stopping plate is provided with a clamping groove which is used for being connected with the stopping block in a pressing mode after the stopping block penetrates through the clamping groove. According to the mini-tiller, the independent gear shifting mechanism is designed, so that the tooth breaking fault is avoided, the reliability is high, and the gear shifting operation cannot be influenced at any angle when the armrest frame is adjusted.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a shift structure of a tiller, in particular to an independent shift tiller. Background technique [0002] Tillers are powered by small diesel engines or gasoline engines, and have the advantages of light weight, small size, strong adaptability, and low price, and have broad application prospects. With the continuous advancement of technology and the increase of demand, the micro tillage machine structure technology and other aspects also need to be improved, so that it should be more suitable for the majority of users. The existing tiller gear shifting technology has a complex structure, large volume, tedious and laborious gear shifting, accompanied by unclear gear changes, resulting in an impact between gears, and the feel is not good, and the reaction is when entering reverse gear It is easy to damage the gear by misoperation, causing damage to the ...
