The utility model relates to an oil gas gathering and transportation apparatus, particularly a novel multifunctional general mechanism integrated a 'C' type general mechanism and an automatic ball collecting barrel into one piece. The multifunctional general mechanism provided includes an inlet valve, the ball collecting barrel, a crude oil outlet, a timing automatic ball collecting valve and a ball collecting box. The multifunctional general mechanism is characterized in that the mechanism is divided into an upper part and a lower part, the upper part is the ball collecting barrel and the lower part is the ball collecting box, the ball collecting barrel is a cylindrical pressure container, the upper part of the side of the ball collecting barrel is distributed with oil inlets which are connected to the station-entering single-well oil transporting pipelines via the inlet valve, a ball receiving funnel is fixed in the ball collecting barrel, the lower end mouth of the ball receiving funnel is fixedly connected to the outlet at the bottom of the ball collecting barrel, the crude oil outlet is also arranged at the bottom of the ball collecting barrel, and the outlet at the bottom of the ball collecting barrel is connected to the inlet of the ball collecting box via the timing automatic ball collecting valve. The novel multifunctional general mechanism provided is good in paraffin removal effects, can independently complete the ball collecting and ball taking operations, and overcomes the defects of independently arranging ball collecting barrels and switching procedures while taking balls.
