The ceding of Taiwan of cropper is typically joined directly together with hydraulic cylinder, and this connected mode has hydraulic cylinder travel when cropper works
The slow defect of larger, taiwan cut off and landing, and the installation site of hydraulic cylinder can also affect the balance of the ceding of Taiwan.
The content of the invention
This utility model is in order to make up the deficiencies in the prior art, there is provided it is a kind of it is reasonable in design, by rotating lever mechanism
The stroke of lifting body is amplified, improves taiwan cut off and landing speed and ensures that the cropper that the ceding of Taiwan is steadily lifted is quick with the ceding of Taiwan
Elevating mechanism, solves problems of the prior art.
This utility model is achieved by the following technical solution：
A kind of cropper ceding of Taiwan fast lifting mechanism, including the bracing frame in cropper frame, described
Support is connected with harvester cutting bench by a rotating lever mechanism, and the rotating lever mechanism is rotated by a lifting body.
The rotating lever mechanism includes a connecting rod of the level above bracing frame, the two ends point of the lifting body
It is not hinged with bracing frame and connecting rod, is respectively symmetrically at the two ends of connecting rod and is installed with a connecting plate, the connecting plate and company
The junction point of extension bar be connecting rod junction point, the connecting plate in connecting rod junction point both sides be respectively arranged at two ends with one with harvest machine cut
Harvester cutting bench junction point and a link point that platform is hinged, the link point on every piece of connecting plate is respectively by being hinged
Compensation linkage be hinged with bracing frame, the harvester cutting bench junction point and link point and connecting rod on every piece of connecting plate
Angle between junction point is obtuse angle.
The lifting body is telescopic hydraulic cylinder, and the two ends of telescopic hydraulic cylinder are hinged with bracing frame and connecting rod respectively.
The compensation linkage is the pull bar that one end screw thread is arranged with connection fork.
Support frame as described above is a support bar.
The quantity of the telescopic hydraulic cylinder is two.
The beneficial effects of the utility model are：Cropper ceding of Taiwan fast lifting mechanism, per block on rotating lever mechanism
Harvester cutting bench junction point on connecting plate and the angle between link point and connecting rod junction point are obtuse angle, pull bar connection
The distance between point and rod connection point are more than the distance between link point and harvester cutting bench junction point, therefore are connecting
The amplification to the flexible stroke of lifting body is capable of achieving when plate rotates, the flexible stroke of telescopic hydraulic cylinder is reduced, can be effectively ensured
Ceding of Taiwan quick and stable is lifted.The length of compensation linkage can connect fork by forward or reverse and be adjusted, it is ensured that elevating mechanism
Balance.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is structural representation of the present utility model.
In figure, 1, bracing frame, 2, connecting rod, 3, connecting plate, 4, connecting rod junction point, 5, harvester cutting bench junction point, 6,
Link point, 7, compensation linkage, 8, telescopic hydraulic cylinder, 9, connection fork.
Specific embodiment
Clearly to illustrate the technical characterstic of this programme, below by specific embodiment, and its accompanying drawing is combined, to this reality
It is described in detail with new.
Embodiment：
As shown in fig. 1, the embodiment includes the bracing frame 1 in cropper frame, and support frame as described above 1 passes through
One rotating lever mechanism is connected with harvester cutting bench, and the rotating lever mechanism is rotated by a lifting body.
The rotating lever mechanism includes a connecting rod 2 of the level above bracing frame 1, the two ends of the lifting body
It is hinged with bracing frame 1 and connecting rod 2 respectively, is respectively symmetrically at the two ends of connecting rod 2 and is installed with a connecting plate 3, the connection
The junction point of plate 3 and connecting rod 2 is connecting rod junction point 4, and the connecting plate 3 in 4 both sides of connecting rod junction point is respectively arranged at two ends with
The one harvester cutting bench junction point 5 being hinged with harvester cutting bench and a link point 6, the pull bar on every piece of connecting plate 3 are connected
Contact 6 is hinged with bracing frame 2 by the compensation linkage 7 being hinged respectively, the harvester cutting bench junction point on every piece of connecting plate 3
Angle between 5 and link point 6 and connecting rod junction point 4 is obtuse angle.
The lifting body is telescopic hydraulic cylinder 8, and the two ends of telescopic hydraulic cylinder 8 are mutually cut with scissors with bracing frame 1 and connecting rod 2 respectively
Connect.
The compensation linkage 7 is the pull bar that one end screw thread is arranged with connection fork 9, can pass through to connect fork 9 during use
Rotating and reverse makes the length of compensation linkage 7 meet work requirements, it is ensured that the balance of elevating mechanism.
Support frame as described above 1 is a support bar.
The quantity of the telescopic hydraulic cylinder 8 is two.
During work, telescopic hydraulic cylinder 8 stretches, and by jacking or the reduction upwards of connecting rod 2, connecting rod 2 is in jacking or reduction
During drive connecting plate 3 to rotate, make to be fixed on the harvester cutting bench lifting of 3 end of connecting plate.Due on rotating lever mechanism
Harvester cutting bench junction point 5 and the angle between link point 6 and connecting rod junction point 4 on every piece of connecting plate 2 is obtuse angle,
Therefore the distance between link point 6 and rod connection point 4 are more than between 5 junction point of link point 6 and harvester cutting bench
Distance, when connecting plate 3 rotates, realize the amplification to stretching the flexible stroke of lifting body, reduce stretching for telescopic hydraulic cylinder
Indention journey, can be effectively ensured the lifting of ceding of Taiwan quick and stable.
