The purpose of this utility model can also further realize by following technical measures.

Aforesaid combine harvester cutting table pendulum loop device, wherein said pendulum ring comprises eccentric interior ring, outer shroud, bearing, a pair of lateral pin, described pendulum ring axis and pendulum annulate shaft axis oblique, ring is fixedlyed connected with the pendulum annulate shaft in the described off-centre, and described outer shroud encircles in eccentric by bearings; One end of described a pair of lateral pin is separately fixed on the outer rim of pendulum ring in twos relatively, and the other end of a pair of lateral pin is hinged with the fork configuration both sides of short balance staff by needle bearing respectively.Described pendulum ring axis angle of deflection is 13 °～17 °.

The utility model structure is comparatively simple, service life length, easy maintenance and installation, low cost of manufacture; the utility model is advanced to existing external pendulum ring on the pendulum annulate shaft that is arranged on ceding of Taiwan front side from the transition axis termination that is positioned on the ceding of Taiwan back side panel; shortened the length of balance staff greatly; transmission of power between transition axis and the pendulum annulate shaft changes the flexible transmission of belt into from existing positive drive; made full use of the function of bel-drivenn overload protection; prevent to put the overload damage of annulate shaft effectively, prolonged the service life of pendulum annulate shaft.

Compare with the cantilever configuration of existing external pendulum ring, the utility model will be put ring and place on the short balance staff, and this short balance staff two end supports has been improved the stress of short balance staff greatly at bearing block III and bearing block IV, has improved reliability of the present utility model.

Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
