[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Loaders are earthwork machines widely used in highway, railway, building, hydropower, port, mine and other construction projects. They are mainly used to shovel soil, sand, lime, coal and other bulk materials, and can also do light shoveling of ore, hard soil, etc. By replacing different auxiliary working devices, they can also do bulldozing, pushing grain, lifting and loading and unloading of other materials such as wood.

[0004] The grain pusher of the loader is mostly used to pile grain in the barn, usually pushing the grain into the grain pile to a certain height. At present, most of the devices connecting the front connecting frame and the rear articulated frame of the grain pusher are welded by angle steel and plate, and the welding process is cumbersome. Since the grain pusher will be in a certain lifting posture during operation, the overall shaking of the connecting frame is obvious, and the weld at the connection is easy to crack, which makes the loader unable to work continuously and stably, reducing the efficiency of pushing grain.
