Significantly improve the operating efficiency of farm machinery.
In order to reach object above, the basic technical scheme of compact farm machinery elevating mechanism of the present invention is：Including it is left,
The portal trestle that the crossbeam of right vertical leading truck support is constituted, is set with the left and right leading truck and constitutes prismatic pair therewith
Left and right liftable supporter, the crossbeam equipped with horizontal extension drive device and be hinged with left side sprocket wheel, duplex chain wheel and
Right side sprocket wheel, the telescopic end of the drive device is connected with left and right branch chain, and the left branch chain bypasses one of duplex chain wheel and returns
It is connected through the sagging upper end with left liftable supporter of left side sprocket wheel after turning, the right branch chain is passed through after duplex chain wheel is another
The sprocket wheel sagging upper end with right liftable supporter in right side is connected.
After the present invention, drive device is horizontally disposed with, therefore structure is extremely compact, can be installed on small space, tool
There is adaptability, be adapted to and various coordinated with agricultural machinery；The flexible displacement of drive device is directly converted to left and right liter by Chain conveyer
The vertical lifting of descending branch support arrangement, therefore fast response time, transmission efficiency；Duplex chain wheel ensure that left and right chaindriven neat
Stepping and ensure that the synchronization lifting of left and right liftable supporter, make mechanism stable reliability of the invention.
Further, the duplex chain wheel is two coaxially connected sprocket wheels, and the angular position of two sprocket wheel staggers half tooth.
Further, the liftable supporter includes roller connecting plate respectively positioned at leading truck inner side and outer side, institute
State roller connecting plate and be respectively provided with guide roller in face of the one side corner of leading truck.
Further, the left and right liftable supporter is connected by the lifting support body of door shape, and the two of the lifting support body
End is connected with the roller connecting plate of left and right liftable supporter respectively, and fixes loading gusset piece respectively.
Further, one of two sprocket wheels of the duplex chain wheel are in same vertical guide, another and right side with left side sprocket wheel
Sprocket wheel is in same vertical guide.
Also further, the crossbeam is provided with horizontal extension drive device by hold-down support, and the drive device is stretched
Contracting end is connected by contiguous block with left and right branch chain.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of one embodiment of the invention.
Specific embodiment
Embodiment one
The compact farm machinery elevating mechanism of the present embodiment is as shown in figure 1, the crossbeam including the support of left and right vertical leading truck 1
10 portal trestles for constituting, are set with the left and right liftable supporter for constituting prismatic pair therewith on left and right leading truck 2.Lifting
Support meanss include roller connecting plate 4 respectively positioned at the inner side and outer side of leading truck 1, and roller connecting plate 4 faces the one of leading truck 1
Face corner is respectively provided with guide roller 3, so as to be allowed to constitute motion vertical prismatic pair freely with leading truck 1.Left and right liter of descending branch
Support arrangement is connected by the lifting support body 5 of door shape, and the two ends for lifting support body 5 connect with the roller of left and right liftable supporter respectively
Fishplate bar 4 is connected, and fixation can install all kinds of loading gusset pieces 2 for needing Lift Part respectively.
Crossbeam 10 is provided with horizontal extension drive device 14 by hold-down support 15（Electricity, liquid, gas drive are moved）And cut with scissors dress
There are left side sprocket wheel 16, duplex chain wheel 11 and right side sprocket wheel 9.
Duplex chain wheel 11 is two coaxially connected sprocket wheels, and one of them is in same vertical guide, another with left side sprocket wheel 16
Same vertical guide is in right side sprocket wheel 9.Under normal circumstances, two sprocket wheel angular positions of duplex chain wheel 11 are consistent, but applicant
Find in practice：When supporting farm machinery two side loads of the Lift Part in lifting process it is unbalanced and easily occur
During trend of vacillating now to the left, now to the right, two sprocket wheel angular positions of duplex chain wheel 11 stagger half tooth, can be applied by left and right branch chain alternation
The high-frequency suppressing of power is waved, and lifting stabilization is helped to maintain all the better.The telescopic end of drive device 14 by contiguous block 13 with it is left,
Right branch chain 12,8 is connected, left branch chain 12 bypass after the single-revolution of duplex chain wheel 11 through left side sprocket wheel 16 it is sagging be located at left liter
By left hook connection, right branch chain 8 is passed through left hanger on descending branch support arrangement upper end crane 5 after duplex chain wheel 11 is another
The sagging right hanger 6 with right liftable supporter upper end crane 5 of right side sprocket wheel 9 is connected by right hook 7.
When drive device 14 is acted, two side chains will be driven, respectively by both sides sprocket wheel, drive lifting support body and loading to connect
Fishplate bar along leading truck steady lifting.
It was verified that compared with prior art, the present embodiment has following remarkable advantage：
