Description
Technical field
The present invention relates to technical field of agricultural machinery, there is differential and the micro- of powershift function ploughs particularly to a kind of
Machine.
Background technology
Tiller, with small diesel engine or gasoline engine as power, has lightweight, small volume, the features such as structure is simple.Micro-
Cultivated machine is widely used in Plain, mountain area, the nonirrigated farmland on hills, paddy field, orchard etc..Mix corresponding equipment to carry out rotary tillage, ploughing, broadcast
Kind, threshing, the operation such as draw water, generate electricity, spraying, spraying, also can draw towed vehicle and carry out short-distance transport, tiller can be in field
Freely travel, user-friendly and deposit, eliminate the worry that large-scale farm machinery cannot be introduced into mountain area field.
But, in practical operation use, one of greatest problem of appearance is exactly not enable to turn to agricultural tiller at present
Curved function, does not enable differential between two road wheels.Just due to there being this defect, therefore now with agricultural tiller to mountain area, mound
The corner arable land in mound area just cannot be carried out farming effectively, even the turning farming in flat arable land also can only lean on tiller strong
Row drags whole machine and realizes its turning function, and this just greatly increases the labour intensity of tiller, decreases actual farming area.
Rearmounted type miniature ploughing machine includes, actuating unit, walking mechanism and operating mechanism, and actuating unit is arranged on walking mechanism
On, operating mechanism can releasably be connected to actuating unit rear end, when operating mechanism is not connected with, armrest seat towards rear, when even
After meeting operating mechanism, in front of armrest seat steering, with the walking work of operating mechanism place direction, walk backward, in the course of work
In stood in front of actuating unit due to operating personnel, in order to prevent operating personnel injured, it is necessary to assure tiller is walked work backward
Can not return during work, can not walk forward.And there is no such protection device in existing rearmounted type miniature ploughing machine, make
Tiller is easily return when operating mechanism works, and produces dangerous.
