Description
Technical field
It the utility model is related to a kind of gear box of micro-cultivator, and in particular to a kind of gear box of micro-cultivator actuating unit.
Background technology
At present, mini-tiller has become increasingly popular as a kind of equipment that can reduce peasant's labor intensity.Mini-tiller moves
Power is the rotation by engine crankshaft, and moment of torsion is transported out, and carrying out two gears by gearbox changes, and realizes fast block or slow
Power, by countershaft output torque, is conveyed to downwards running gear or coulter through the transmission shaft vertical with countershaft, made by speed gear rotating speed
Mini-tiller is walked or arable land.
The power drive mechanism of existing gear box of micro-cultivator, usually all only has a main shaft, a countershaft, major and minor axis
Between by two gear gear pairs carry out two gear speed changes export power, main shaft pass through the bent axle of clutch and engine connect, transmit
The moment of torsion of bent axle conveying, this structure make the rotating speed of main shaft very high, turn even if exporting slow block after slowing down by speed reducing gear pair
Speed, the speed of its slow block rotating speed remain on the speed for comparatively fast, causing operator not catch up with running gear, the operation control of operator
System is very laborious, runs out of space, and is unfavorable for operator and manipulates mini-tiller.
Moreover, with the development of agricultural tool, it is desirable to be driven using the engine of mini-tiller as power source
Additional equipment work, can pass through shaft coupling by the additional equipment such as water pump, grass mower, grass-mowing machine, plough, spraying device
It is connected with the main shaft or countershaft of gear box of micro-cultivator and drives its work.But since gearbox body only has fast block or slow block
Two kinds of rotating speeds, and both rotating speeds are all of a relatively high, the needs driven with this be movably walking such as grass mower, grass-mowing machine, trench digging
The additional equipment speed of travel such as device is also relatively fast, and it is difficult to adapt to keep up with so fast speed and cause as cut grass to make operator
These additional equipments such as machine, grass-mowing machine, plough can not be used cooperatively with mini-tiller, can only use the power set carried, both
These additional equipment prices are increased, and increase the volume and weight of these additional machines, inconvenience is brought to user.And
And since mini-tiller usually only has two kinds of speed, and the working speed that different additional equipments needs is different, both
Rotating speed is difficult to the work requirements for meeting different additional equipments, narrow scope of application.So the gear box of micro-cultivator of the prior art is adopted
It is all inapplicable to many additional equipments, it is impossible to meet market and the expectation of user with the structure of single main shaft.
The content of the invention
The purpose of this utility model is that usually there was only single main shaft for existing Mini-tiller power gearbox, and main shaft is directly defeated
It is too fast to go out power rotating speed, it is impossible to be used in directly drive insufficient existing for additional equipment, there is provided a kind of power of gear box of micro-cultivator
Transmission device, it has multiple output terminals, can either pass through the second main shaft or the additional equipment of countershaft driving, moreover it is possible to realize more
The fast demand of gear, satisfaction drive the needs of a variety of additional equipments with Mini-tiller power.
What the technology of the utility model was realized in：A kind of gear box of micro-cultivator actuating unit, including main shaft, pair
