Abstract
The utility model relates to a reduction gearbox of a micro power tiller; an input shaft and a driven shaft are vertically arranged in front of a box body which is raised upwards, an output shaft of a differential mechanism is arranged at the rear of the box body, the input shaft outside the box body is provided with a microspecimen type drive clutch, the front part of the reduction gearbox is convex, and an engine is installed at the rear of the reduction gearbox, so that the whole volume of the micro power tiller is reduced; more particularly, the output shaft of the differential mechanism can cause a left wheel and a right wheel to make differential rotation, thereby the micro power tiller is flexibly steered and conveniently operated.
Description
Technical field
The utility model relates to the reduction box device of farm machinery device, particularly agricultural mini-size tillage machine.
Background technology
The reduction box or the gearbox of existing agricultural mini-size tillage machine are a kind of common gear reduction box or gearbox, though can finish deceleration, but its structure structure can not fully satisfy the handling characteristics of mini-size tillage machine, install side by side before and after reduction box and the engine during use, overall volume is big, and wheel is installed on the output shaft of reduction box or is installed on the supporting leg by the belt pulley transmission its left and right sides wheel speed unanimity, the turn performance of the machine of ploughing is very poor, the operation effort.
The utility model content
It is good that the purpose of this utility model provides a kind of serviceability, is specially adapted to the reduction box device of mini-size tillage machine.
The utility model is erect to arrange in the front portion of reduction box casing and is provided with power shaft and driven shaft, power shaft and driven shaft are provided with intermeshing travelling gear in the casing, be provided with the differential mechanism output shaft at the rear portion of casing, driven shaft is connected by chain gear transmission with differential mechanism, outside casing, be provided with abrasive disc formula transmission clutch on the power shaft, on urceolus on the clutch, be provided with the input drive sprocket.
The utility model drives power shaft by clutch, after driving shaft and driven shaft gear deceleration, drive the differential mechanism output shaft, the anterior projection of reduction box, the engine of the machine of ploughing is installed on this reduction box rear portion, the mini-size tillage machine overall volume is dwindled, and particularly the differential mechanism output shaft can make the left and right wheels differential rotate, mini-size tillage machine is turned to flexibly, handle easy and convenient.
