Abstract

The invention discloses a traveling driving device for mini-tiller, which is arranged below a speed shifting mechanism in a traveling box. The traveling driving device comprises a bevel gear shaft, the upper end of the bevel gear shaft is connected with a first driven bevel gear, and the first driven bevel gear is meshed with a conical gear on an auxiliary shaft of the speed shifting mechanism; and a conical gear at the lower end of the bevel gear shaft is meshed 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. According to the invention, the conventional chain drive is abandoned, and the gear drive is adopted; and compared with a chain, the gear is longer in service life, higher in drive efficiency, higher in transfer power and larger in speed range.

Description

Mini-size tillage machine walking transmission device

Technical field

The present invention relates to the miniature cultivation machinery of a kind of multifunctional agricultural, especially a kind of mini-size tillage machine walking transmission device.

Background technology

Mini-size tillage machine is a power with small diesel engine or gasoline engine, has in light weightly, and volume is little; Characteristics such as simple in structure; Adaptable across the Plain, the nonirrigated farmland on mountain area, hills, paddy field, orchard etc., mini-size tillage machine is mixed corresponding facility can draw water, generate electricity, spray operations such as medicine, spray, also can draw towed vehicle carries out short-distance transport; Mini-size tillage machine can freely be exercised in the field; User-friendly with deposit, saved the worry that large-scale farm machinery can't get into field, mountain area piece, be 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 big.

Summary of the invention

The invention 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 object of the invention can reach through following measure: a kind of mini-size tillage machine walking transmission device; Be installed on the gear below in the walking case; Said walking transmission device comprises angular wheel shaft; Said angular wheel shaft upper end is connected with first driven bevel pinion, the bevel gear engagement on said first driven bevel pinion and the gear countershaft; The bevel gear of said angular wheel shaft lower end is engaged with second driven bevel pinion, and said second driven bevel pinion is connected with axle sleeve, and said axle sleeve is connected with output shaft, and said output shaft connects rotary tillage mechanism.

The technique scheme difference with the prior art is: at first, the present invention has 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 bigger; Secondly, walking case and gearbox are same casing, and structure is compact more, and difficulty of processing reduces.

Further, for satisfying the required transmission moment of torsion of mini-size tillage machine, prevent that output shaft and axle sleeve from sliding, said second driven bevel pinion is connected with axle sleeve is coaxial, and said axle sleeve is interior six sides cover, and output shaft is six square shafts.

Further, for making the stressed more even of angular wheel shaft, said angular wheel shaft is connected with the first driven bevel pinion spline.

It is big that the present invention has bearing capacity, and running is steady, and noise is little, and efficient is high, and the characteristics that power loss is little can satisfy the requirement of mini-size tillage machine to transmission of power.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:

Fig. 1 is the structural representation of mini-size tillage machine walking transmission device embodiment of the present invention;

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; Said walking transmission device comprises angular wheel shaft 2, and said angular wheel shaft 2 upper ends are connected with the axis hole spline of 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 second driven bevel pinion; The axis hole of said second driven bevel pinion 3 is equipped with interior six sides cover 4; Interior six sides cover 4 is penetrated with six square shafts 5; Interior six sides cover, 4 and six square shafts 5 are fastening through pin, and 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 through first driven bevel pinion 1; Rotate with interior six sides cover 4 thereby drive second driven bevel pinion 3, six square shafts, 5 outputting torsions that interior six square sockets 4 connect drive the outer rotary tillage mechanism of walking case and carry out farming.

The detailed description that the above is merely preferred embodiment of the present invention is not to be used for limiting the present invention, and the embodiment of all similar variations of doing according to creation spirit of the present invention all should be contained among the present invention.
