Central axes between movable tooth block 22 and mobile tooth block 22 overlap.
The working principle of the present embodiment: when using the farm machinery chassis balanced convenient for automatic adjustment wheelspan, firstly, when needing
When the wheelspan of chassis two sides being adjusted, according to Fig. 1-3, firstly, the first telescopic cylinder 10 in starting Fig. 1, makes
Obtaining the first telescopic cylinder 10 drives the connecting rod 8 on its top to carry out mobile working, during connecting rod 8 carries out mobile, meeting
The thrust wheel 11 of its bottom is driven to carry out lifting work, it, can be to the crawler belt 2 of its outside during thrust wheel 11 is gone up and down
Support force is reduced, and then loosens crawler belt 2 gradually, and directive wheel 3, moping pulley 6, driving wheel 1 and top can be made
End breaket 4 carries out decline work, during bracket 4 is declined on top, can make the connecting bracket 19 of its bottom connection
Also decline work is carried out, during connecting bracket 19 is declined, its outside can be made to connect by branch stent 1901
Support rod 14 and universal wheel 15 also carry out decline work, when thrust wheel 11 continue rise height be greater than universal wheel 15 and ground
Between height when, entire chassis will be supported work by support rod 14 and universal wheel 15, and entire thrust wheel 11 and be carried out
Will occur hanging state under the supporting role of support rod 14 and universal wheel 15 with 2, can start in Fig. 2 as a result,
Second telescopic cylinder 18, so that the second telescopic cylinder 18 carries out contraction work, in the telescopic process of the second telescopic cylinder 18, just
It will drive entire connecting bracket 19 and top bracket 4 also carry out mobile working, during connecting bracket 19 carries out mobile, just
Meeting completes the effect that the wheelspan of two sides is adjusted so that support rod 14 and universal wheel 15 are moved, and thus just makes
During carrying out wheelspan adjusting, will not coming into contact in a large area due to thrust wheel 11 and crawler belt 2 and ground, cause frictional force
It is excessive should wheelspan adjust stabilization continuity effect；
During entire chassis is worked, according to Fig. 4-6, due to moping pulley 6 the inside of preformed groove 1902 into
Row limit movement, and driving wheel 1 and directive wheel 3 carry out limit movement under the action of limited block 5, and then can protect well
Entire chassis is demonstrate,proved during carrying out mobile, is not in the phenomenon that crawler belt 2 is detached from, meanwhile, in the second telescopic cylinder
18, which carry out flexible drive connecting bracket 19, carries out during moving, since limited block 5 is biased to the side of the second telescopic cylinder 18
Setting, so that during connecting bracket 19 drives driving wheel 1 and directive wheel 3 to carry out mobile, under the action of limited block 5 just
During just not appearing in progress wheelspan adjusting as a result, there is the phenomenon that crawler belt 2 loosens so that crawler belt 2 is moved in meeting
Occur；
Later, starting first motor 16 and the second motor 17, mobile working can be carried out by driving driving wheel 1 to carry out operating,
During carrying out mobile, due to the setting of mobile tooth block 22, it can be very good and the rotation on driving wheel 1 and directive wheel 3
Tooth block 20 is engaged connection, drives entire agricultural machinery to be moved so that entire chassis is mobile, to complete a series of
Work.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
