It is used cooperatively with bearing pin, other pin-and-holes are standby, used when the pin-and-hole used goes wrong or damaged.
The suspension arrangement is applied to the use of middle-size and small-size agricultural machinery and implement, can adjust lower pull bar hinge according to actual operation requirements
The position of contact, ensures the hoisting power of hoisting mechanism, at the same can or lower pull bar uneven on work-yard ground because of outer masterpiece
During with bending, by adjusting the position of lower pull bar pin joint, ensureing the stationarity of agricultural machinery and implement mounting, reducing the pendulum of agricultural machinery and implement
Dynamic amplitude, increases its stability；The use of adjustable drawbar can increase rigidity when drop-down joint element for bar uses.
The present invention has advantages below compared with prior art：
（1）The present apparatus can be according to actual operation requirements, by rotating rod connecting shaft, the appropriate position for shortening lower pull bar pin joint
Put, and then increase the hoisting power of hoisting mechanism, reduce oil consumption to a certain extent；
（2）During suspension arrangement use, if lower pull bar bends because being acted on by external force, left and right two can be caused
Difference in length between lower pull bar, now, its entire length, Jin Eryou can be adjusted by actual conditions adjusting yoke connecting shaft
Effect avoids agricultural machinery and implement caused by the drop-down of left and right two pole length difference from swinging；
（3）Operating mode is analyzed during by overall structure and work, is connected pin-and-hole connector and pin-and-hole connecting shaft with pin
Connect, spacing pole length adjusted by rotating pin hole connecting shaft, is then being mounted, can applied under the conditions of not level land condition,
Agricultural machinery and implement amplitude of fluctuation is reduced, increases its stability；
（4）Adjustable drawbar is set between joint element for bar is pulled down, coordinates the gag lever post after optimization to use, by increasing capacitance it is possible to increase elevating lever liter
Stability during drop, while the rigidity of drop-down joint element for bar can be increased.
