The right side of above-mentioned left side output axle shaft is provided with connection parent part, and the left side of differential lock is provided with connection bull.
Above-mentioned connection parent part is a groove caving inward, and connecting bull is an outwardly projection, and described groove and protruding sectional shape are quincunx.
The right side of above-mentioned differential lock is provided with spring, and this spring is arranged in differential seat.
One end of above-mentioned differential lock is arranged on the outside of differential seat.
On above-mentioned right side output axle shaft, be provided with umbrella gear.
On above-mentioned disengaging pawl, be provided with bracing wire interface.
The utility model beneficial effect compared to existing technology: the utility model is connected or departs from left side output axle shaft by differential lock, can allow agricultural ploughing machine keep straight on or 360 ° rotate freely, in addition, differential lock of the present utility model is built-in, be that differential lock is arranged in differential seat, compact structure like this, ploughs effective.

Embodiment
Below in conjunction with drawings and Examples, to embodiment of the present utility model as preferred detailed description.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Fig. 1-Fig. 6, a kind of differential mechanism, comprise differential seat 1, on differential seat 1, be provided with a pair of planetary pinion 2, be provided with left side output axle shaft 3, right-hand member at the left end of differential seat 1 and be provided with right side output axle shaft 4, the inner that wherein the inner of left side output axle shaft 3 is provided with left sun gear 5, right side output axle shaft 4 is provided with right sun gear; Described planetary pinion 2 and left sun gear 5, right sun gear are mutually vertical and intermeshing, in described differential seat 1, are provided with differential lock 7, and differential lock 7 is connected with left side output axle shaft 3; On differential seat 1, be arranged with disengaging pawl 11, disengaging pawl 11 left side be provided with suitable separation block 13(separation block 13 and fix).
As the first selection, the right side of above-mentioned left side output axle shaft 3 is provided with and connects parent part 9, and the left side of differential lock 7 is provided with and connects bull 10.
As the first selection, above-mentioned connection parent part 9 is a groove caving inward, and connecting bull 10 is an outwardly projection, and described groove and protruding sectional shape are quincunx.
As the first selection, the right side of above-mentioned differential lock 7 is provided with spring 8, and this spring 8 is arranged in differential seat 1.
