Description
Technical field
The invention belongs to mini-tiller technical field, specifically, more particularly to a kind of mini-tiller integrated form main transmission babinet.
Background technology
Mini-tiller using small diesel engine or gasoline engine as power, have it is light-weight, it is small, it is simple in structure the features such as.It is micro-
Cultivated machine is widely used in Plain, mountain area, the nonirrigated farmland on hills, paddy field, orchard etc..Mixing corresponding equipment can be drawn water, generated electricity, be sprayed
The operations such as medicine, spray, can also draw towed vehicle and carry out short-distance transport, mini-tiller can freely be exercised in field, made easy to user
With and storage, eliminate the worry that large-scale farm machinery cannot be introduced into mountain area field, be vast farmers friend substitute ox plough most
Good selection.
At present, the engine that mini-tiller uses is generally divided into two kinds of horizontal-shaft engines and vertical shaft generator, engine
Directly it is connected with gearbox, after the power of engine changes moment of torsion by gearbox, then drives traveling wheel or coulter.In order to increase
The function of mini-tiller, is equipped with suction pump, generator, the functional component such as chemical spraying device on mini-tiller, these components be required to from
Gearbox power taking, it is common practice to gearbox is divided into main transmission box and slave drive case two parts, is set in main-gear box
Put belt speed change mechanism, the driving shaft of the power drive belt speed change mechanism of engine, functional component is from belt speed change mechanism
Driving shaft power taking, and the driven shaft of belt speed change mechanism driving slave drive case, slave drive case drive traveling wheel or coulter again.
Existing main transmission babinet is not only complicated, and processing and fabricating is difficult, and production cost is high, and internal space layout is unreasonable,
So that the installation of belt speed change mechanism is extremely inconvenient.In addition, engine uses perpendicular shaft configuration, installed on main transmission babinet
Convenience is poor, and can increase the height dimension of complete machine.
The content of the invention
In view of the drawbacks described above of the prior art, the technical problems to be solved by the invention are to provide a kind of main biography of integrated form
Dynamic babinet.
