Description
Technical field
The present invention relates to the transmission device of farm equipment, particularly relate to a kind of dry land spraying machine scalable drive axle.
Background technology
Present domestic dry land spraying machine drive wheel is a front-wheel, and trailing wheel is a flower wheel, and rear track can not be adjusted.Spraying machine because propulsive effort is little, runs into soft road surface when farm work, skidding and can't go in the frequent original place of spraying machine, causes the operator to spray medicine to crops, reduced work efficiency.Because track rear can not be adjusted, and spraying machine only uses a kind of field of wheelspan, the scope that is suitable for the field is narrower simultaneously, and the spraying machine degree of utilization is lower.
Summary of the invention
The technical matters that (one) will solve
The technical matters that the present invention will solve is: existing spraying machine trailing wheel is a flower wheel, no propulsive effort; Track rear is fixed, and can not adapt to multiple field environment.
(2) technical scheme
In order to solve the problems of the technologies described above, the present invention provides a kind of later-model dry land spraying machine scalable drive axle, and this scalable drive axle is on the trailing wheel of spraying machine; Form by supporting construction, drive mechanism, roll adjustment structure; Drive mechanism comprises bridge drive mechanism and wheel drive mechanism, and wherein, supporting construction comprises axle housing, external support board and interior stay bearing plate; External support board and interior stay bearing plate link together, and drive mechanism and roll adjustment structure are installed on the supporting construction.The bridge drive mechanism is made up of transmission assembly, belt pulley, differential assembly, axle tube, semiaxis, and Pulley shaft connects the input shaft of transmission assembly, and transmission assembly connects differential assembly, and the output shaft of differential assembly connects semiaxis; Axle tube is connected through the key that can laterally slide with semiaxis, the input end of axle tube outer end fifth wheel drive mechanism.Above-mentioned roll adjustment structure is characterised in that there is flat key the inside, outer end of axle housing, and the sleeve pipe cylindrical outer surface has long keyway; Cooperate with the flat key on the axle housing; Sleeve pipe can slide along the flat key end face, and sleeve pipe outer end and interior stay bearing plate are fixed, and sleeve pipe inner end and baffle plate are fixed; Bearing is equipped with at the two ends of inside pipe casing, supports axle tube.
After the engine operation, from power process belt pulley, transmission assembly and the rotation of differential assembly drive semiaxis of driving engine, and drive and the rotation of semiaxis bonded assembly axle tube.Axle tube driven wheel drive mechanism reaches wheel with power, drives vehicle '.
Axle tube and semiaxis can be along the keyway side travels, and interior stay bearing plate and baffle plate are limited in bearing between sleeve pipe and the axle tube, so sleeve pipe and axle tube can laterally link.Because axle tube is that key is connected with semiaxis, therefore do not influence the transmission of power between them simultaneously, still can give the spraying machine trailing wheel with transmission of power through aforementioned driving parts.Sleeve pipe, interior stay bearing plate and external support board all are fixed together, and during its side travel, can drive the trailing wheel side travel, thereby change wheelspan.
(3) beneficial effect
Technique scheme has following advantage: back axle changes drive axle into by driven bridge, increases the propulsive effort of spraying machine, has improved the various ground-surface abilities that adapt to, and is fit to wider field road conditions.The back axle wheelspan can be adjusted, and can use the field of crops different spacings, improves the vehicle degree of utilization, reduces operator's use cost.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention describes in further detail.Following examples are used to explain the present invention, but are not used for limiting scope of the present invention.
As shown in Figure 1, the drive axle in the present embodiment by transmission assembly 1, belt pulley 2, axle housing 3, differential assembly 4, nut 5, wheel disc 6, wheel shaft 7, wheel 8, form.Wherein, Pulley shaft connects the input shaft of transmission assembly 1, and transmission assembly 4 connects differential assembly 4, and the output shaft of differential assembly 4 connects semiaxis 22, and axle tube 21 is connected for the long keyway spline with semiaxis 22.Axle tube 21 outer ends are equipped with flat key and are connected minor sprocket 15.Minor sprocket 15 drives hinge wheel 10 through chain 13, and hinge wheel 10 is installed on the wheel shaft 7, and wheel disc 6 is equipped with in its inner, and wheel disc 6 is through bolt wheel 8, and wheel disc 6 outer ends are fixing by nut 5.
