LOWER TRACTION ROD FOR TRACTOR HINGE Russian patent published in 2011 - IPC A01B59/06 

FIELD: agriculture.

SUBSTANCE: lower traction rod consists of the following components: the first spreader, at the end of which there is a channel and a hollow space adjacent to the channel, the second spreader arranged with the possibility of insertion and displacement in the channel and comprises a groove, a stop element matched with hollow space to fix the second spreader on the first spreader. The stop element is arranged with the possibility of displacement between position of unblocking, at one side, where it is located inside hollow space, and position of fixation, at the other side, where it is inserted in channel, and whenever the second spreader is located in the channel, the stop element fixes it in it, penetrating into the groove. The traction rod comprises a spring, which retains the stop element in position of fixation and comprises the first arm adjacent to wall that limits hollow space and the second arm adjacent to the stop element, and grip. The grip passes through hole in wall that limits hollow space and is connected to the stop element. Using the grip, the operator may move the stop element in position of unblocking. The spring retains the stop element in hollow space by means of its spring force.

EFFECT: reduced labour intensiveness of assembly and simplified design.
