Abstract

The utility model discloses a telescopic mechanism for ton bag throwing, which comprises a throwing bucket and a connecting arm, and the connecting arm is movably connected onto the throwing bucket. The connecting arm is connected with a telescopic structure, the telescopic structure is connected with a fixing frame, a lubricating structure is installed in the fixing frame, and a plurality of guide rods are installed in the fixing frame in a sliding mode. Through the arrangement of the oil cylinder, the connecting arm can be driven to stretch out and draw back in the large forklift arm, then the moving distance of the throwing bucket can be adjusted, parking can be conducted at the position far away from a dangerous area, then the throwing bucket is adjusted to stretch into the dangerous area to throw a ton bag, the operation safety is improved, and the working efficiency is improved. And lubricating oil can be sprayed on the surface of the connecting arm by starting the suction pump and can be brought into the forklift large arm along with stretching of the connecting arm, the lubricating effect is achieved, the friction force between the connecting arm and the forklift large arm is reduced, the service life of the forklift large arm is prolonged, and stretching is smoother.
