Abstract
The utility model relates to a transmission for mini-tillers, in particular to a rear transmission for the rotary tillage of mini-tillers, which comprises a case, a power output spindle, a travelling wheel axle and a rotary tillage output shaft, and the power output spindle, the travelling wheel axle and the rotary tillage output shaft are arranged in the case; the power of the power output spindle is transmitted to an auxiliary shaft through gears, a worm which can synchronously rotate along with the auxiliary shaft is fixed on one end of the auxiliary shaft, and a worm wheel mounted on the travelling wheel axle can be driven by one end of the worm to rotate; and a driving bevel gear is mounted on the other end of the worm, and is engaged with a driven bevel gear mounted on the rotary tillage output shaft. Because of the structure, the rear transmission has the advantages that: travelling power output and rotary tillage power output are independent from each other, the efficiency of power transmission is high, and a rotary tillage mechanism is convenient to mount and dismount and easy and convenient to operate.
Description
Technical field
The utility model relates to transmission device of mini-tiller, and particularly the output of a kind of walking and rotary tillage power is separate, power transmission efficiency is high, the rotary cultivator attachment loading and unloading are convenient and operate light mini-size tillage machine rotary tillage rear transmission device.
Technical background
Along with the development of social productive forces, miniature agricultural is popularized gradually with machinery.Mini-size tillage machine in the market generally comprises engine, and running gear and the rotary cultivator attachment of power is provided by engine, and operating grip.Yet the Mini-tiller power transmission of existing structure is to pass to running gear and rotary cultivator attachment by gearbox, and rotary cultivator attachment can only be installed in the front end of mini-size tillage machine, so that the efficient of transmission of power is low, transmitting torque is little, operating efficiency is just low.Because running gear and rotary cultivator attachment share same gearbox, so that complicated operation.The mini-size tillage machine of prior art in use, rotary ploughing part is easy to damage, the maintenance loading and unloading are difficult.
In sum, the deficiency that the mini-size tillage machine of prior art exists is: power transmission efficiency is low, transmitting torque is little, the preposition so that complicated operation of rotary cultivator attachment and easily assembling not.
Summary of the invention
For the problems referred to above, the purpose of this utility model provides a kind of walking and the output of rotary tillage power is separate, power transmission efficiency is high, the rotary cultivator attachment loading and unloading are convenient and operate light mini-size tillage machine rotary tillage rear transmission device.
For realizing that the technical scheme that the utility model purpose adopts is: a kind of mini-size tillage machine rotary tillage rear transmission device, comprise casing, be arranged on power output main shaft, live axle and rotary tillage output shaft in the casing; Wherein: to countershaft, an end of countershaft is fixed with the worm screw with the countershaft synchronous rotary to the power of described power output main shaft by gear transmission, and worm screw one end drives the turbine rotation that is installed on the live axle; In another termination of worm screw driving bevel gear is installed, driving bevel gear and the driven bevel pinion engagement that is installed on the rotary tillage output shaft.
For making control behaviour convenient, on the described countershaft travelling gear is installed, the output gear engagement on travelling gear and the power output main shaft realizes transmission of power; Travelling gear is also realized gear control with the back gear engagement that is installed on the Control Shaft.
Because said structure, the utility model has in use been realized power is independently flowed to respectively live axle and rotary tillage output shaft, has realized that namely the output of walking and rotary tillage power is separate; Because power adopt to adopt turbine to be combined transmission with worm screw, its power transmission efficiency is high, transmitting torque is large, and in use, not needing just can be with the convenient loading and unloading of rotary tillage cutter with the defeated demolition of rotary tillage power, realize maintenance or change rotary tillage cutter, reached rotary cultivator attachment and loaded and unloaded easily purpose; Because the setting of back gear and Control Shaft, so that control walking or rotary tillage are light.
Description of drawings
Device of the present utility model can further specify by the non-limiting embodiment that accompanying drawing provides.
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure: 1, turbine; 2, live axle; 3, worm screw; 4, power output main shaft; 5, countershaft; 6, cold feed pipe; 7, driving bevel gear; 8, driven bevel pinion; 9, rotary tillage output shaft.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing 1, the mini-size tillage machine rotary tillage rear transmission device in the accompanying drawing comprises casing, is arranged on power output main shaft 4, live axle 2 and rotary tillage output shaft 9 in the casing; Wherein: to countershaft 5, an end of countershaft 5 is fixed with the worm screw 3 with countershaft 5 synchronous rotaries to the power of described power output main shaft 4 by gear transmission, and worm screw 3 one ends drive turbine 1 rotation that is installed on the live axle 2; In worm screw 3 another terminations driving bevel gear 7 is installed, driving bevel gear 7 and driven bevel pinion 8 engagements that are installed on the rotary tillage output shaft 9.This structure in use, the power of engine passes to countershaft 5 by power output main shaft 4, specifically the travelling gear engagement realization by installing on the output gear on the power output main shaft 4 and the countershaft 5; After power was passed on the countershaft 5, power drove turbine 1 rotation by worm screw 3 one ends, and turbine 1 live axle 2 rotates, and the road wheel that control is installed on the live axle 2 drives whole device walking; Power also meshes rear rotary tillage output shaft 9 rotations that drive by the driving bevel gear 7 that install worm screw 3 another terminations with driven bevel pinion 8, and rotary tillage output shaft 9 drives the rotary blade that is installed on the rotary tillage output shaft 9 and rotates the arable land.
For making operation control behaviour convenient, on the described countershaft 5 of above-described embodiment travelling gear is installed, the output gear engagement on travelling gear and the power output main shaft 4 realizes transmission of power; Travelling gear is also realized gear control with back gear 6 engagements that are installed on the Control Shaft.
In the said structure: the two ends of described live axle 2 is equipped with road wheel.On the described rotary tillage output shaft 9 rotary blade is installed.
In sum, this structure has realized that the output of walking and rotary tillage power is separate, power transmission efficiency is high, the rotary cultivator attachment loading and unloading are convenient and has operated light.
