Abstract
The utility model discloses a traveling transmission device of a micro-tillage machine, and the traveling transmission device is installed below a speed-changing mechanism inside a traveling box, and the traveling transmission device comprises a bevel gear shaft, wherein the upper end of the bevel gear shaft is connected with a first driven bevel gear, and the first driven bevel gear is engaged with a conical gear on a speed-changing mechanism auxiliary shaft; and a conical gear on the lower end of the bevel gear shaft is engaged with a second driven bevel gear, the second driven bevel gear is connected with a shaft sleeve, the shaft sleeve is connected with an output shaft, and the output shaft is connected with a rotary tillage mechanism. Firstly, the traveling transmission device abandons the traditional chain transmission way and adopts the gear transmission way, and compared with a chain, the gears are longer in service life and higher in transmission efficiency; and moreover, the transmission power and the speed range are larger.
Description
Technical field
The utility model relates to a kind of Multifunctional agricultural micro cultivator tool, especially a kind of mini-size tillage machine walking transmission device.
Background technology
Mini-size tillage machine is take small diesel engine or gasoline engine as power, have lightweight, volume is little, the characteristics such as simple in structure, be widely used in the nonirrigated farmland, paddy field, orchard on Plain, mountain area, hills etc., mini-size tillage machine is mixed corresponding facility can draw water, generate electricity, spray the operations such as medicine, spray, also can draw towed vehicle and carry out short-distance transport, mini-size tillage machine can freely travel in the field, user-friendly and deposit, having saved the worry that large-scale farm machinery can't enter the mountain area field, is that the vast farmers consumer substitutes the optimal selection that ox is ploughed.
At present the running gear of mini-size tillage machine part is general adopts chain drive or carrier gear transmission, and its shortcoming is: chain elongates easily and fracture, transmission efficiency are low, causes the loss of mini-size tillage machine transmission power large.
The utility model content
The utility model is intended to provide the mini-size tillage machine walking transmission device of a kind of transmission efficiency height and maintenance convenient for assembly.
The purpose of this utility model can reach by following measures: a kind of mini-size tillage machine walking transmission device, be installed on the gear below in the walking case, described walking transmission device comprises angular wheel shaft, described angular wheel shaft upper end is connected with the first driven bevel pinion, the bevel gear engagement on described the first driven bevel pinion and the gear countershaft; The bevel gear of described angular wheel shaft lower end is engaged with the second driven bevel pinion, and described the second driven bevel pinion is connected with axle sleeve, and described axle sleeve is connected with output shaft, and described output shaft connects rotary tillage mechanism.
The technique scheme difference with the prior art is: at first, the utility model has been abandoned traditional chain drive, adopts gear drive, and gear is compared to chain, and its longer service life, transmission efficiency are higher, and transmitted power and velocity interval are larger; Secondly, walking case and gearbox are same casing, and structure is compacter, and difficulty of processing reduces.
Further, slide for preventing output shaft and axle sleeve, described the second driven bevel pinion is connected with axle sleeve is coaxial, and described axle sleeve is interior six square sets, and output shaft is six square shafts.
Further, for making the stressed more even of angular wheel shaft, described angular wheel shaft and the first driven bevel pinion spline joint.
It is large to the utlity model has bearing capacity, smooth running, and noise is little, and efficient is high, and the characteristics that power loss is little can satisfy mini-size tillage machine to the requirement of transmission of power.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model mini-size tillage machine walking transmission device embodiment;
Embodiment
Embodiment: as shown in Figure 1, a kind of mini-size tillage machine walking transmission device is installed on the gear below in the walking case of mini-size tillage machine; Described walking transmission device comprises angular wheel shaft 2, the axis hole spline joint of described angular wheel shaft 2 upper ends and the first driven bevel pinion 1, the bevel gear engagement on the countershaft in this first driven bevel pinion 1 and the gearbox; The bevel gear of angular wheel shaft 2 lower ends and 3 engagements of the second driven bevel pinion, the axis hole of described the second driven bevel pinion 3 is equipped with interior six square sets 4, interior six square sets 4 are penetrated with six square shafts 5, interior six square sets 4 and six square shafts 5 are fastening by pin, the both ends horizontal of six square shafts 5 is stretched out the left and right sides side opening on the walking case, and the rotary tillage mechanism outer with case is connected.
During the mini-size tillage machine walking, countershaft in the gearbox transmits torsion to angular wheel shaft 2 by the first driven bevel pinion 1, thereby drive the second driven bevel pinion 3 and 4 rotations of interior six square sets, six square shafts, 5 outputting torsions that interior six square sets 4 connect drive the outer rotary tillage mechanism of walking case and carry out farming.
The above is the detailed description of the utility model preferred embodiment only, is not to limit the utility model, and the embodiment of all similar variations of doing according to creation spirit of the present utility model all should be contained among the utility model.
