This application discloses a rubber reeling chain device and a corn harvester, belonging to the field of agricultural machinery technology. It includes a reeling chain body, a pusher plate, a limiting component, and a reeling chain core. The reeling chain body has a ring-shaped structure, with pushers spaced apart on the outer side of the reeling chain body. Both the reeling chain body and the pushers are made of rubber. The limiting component is located on the inner side of the reeling chain body and is used to install and limit the reeling chain core. The reeling chain cores are arranged along the inner side of the reeling chain body, forming a limiting cavity between adjacent reeling chain cores. The reeling chain body is used to engage with the teeth of an external sprocket through the limiting cavity and thus wrap around the sprocket. The pusher plate is driven by the reeling chain body to push the material. The reeling chain body and pusher plate are made of rubber, and the reeling chain cores are arranged and installed on the inner side of the reeling chain body through the limiting component, facilitating the engagement of the reeling chain cores with the teeth of the external sprocket and making it easier to replace a metal chain.

The utility model discloses a double -leaf door structure, including left door leaf, right door leaf, left card seat, right card seat and fastener, left door leaf includes left door panel and left decorative board, and right door leaf includes right door panel and right decorative board, and left card seat, right card seat all are equipped with limiting slot, installation cavity on, and left card seat, right card seat are respectively clamped in the side of left door leaf, right door leaf through limiting slot, and left decorative board is pressed in left door panel front, and right decorative board is pressed in right door panel front, and the one end of fastener is from installation cavity and is screwed in the side of left door panel, right door panel, and the other end of fastener is located in installation cavity, and the one end of left card seat towards right card seat is provided with baffle, and the baffle covers in right card seat outside or separates with right card seat with the rotation of left door leaf. Through above -mentioned structure can be more convenient to replace internal decorative surface under the condition that left door panel, right door panel appearance is not changed, and the use is facilitated.
