The header includes a header mounting frame 1, a power system 2, and a crop-lifting mechanism 3. The header mounting frame 1 is mounted on the corn harvester as a connecting part. Several crop-lifting mechanisms 3 are provided and mounted on the header mounting frame 1. The power system 2 is mounted on the header mounting frame 1 and drives the crop-lifting mechanisms 3. The power from the corn harvester is transmitted to the power system 2, which then distributes the output power. The crop-lifting mechanisms 3 are used for feeding and lifting crops.

[0041] The hinged part 45 and the mounting part 46 in the scheme can adopt an integral molding structure, which is directly formed into a complete structure through stamping and bending, so as to ensure the integrity of the structure, reduce the production cost, improve the strength of the product, and reduce the production process.

[0042] The contact pad 43 is provided with a covering groove and a filling part, the covering groove is matched with the bent edge 47, the bent edge 47 is embedded in the covering groove, the matching of the bent edge 47 and the covering groove can ensure the stable connection of the contact pad 43 and the hinge part 42, prevent the abrasion caused by the reciprocating shaking of the contact pad 43 on the hinge part 42, and wrap the corners of the hinge part 42 to prevent the abrasion of the hinge part 42 caused by the contact with crops, thereby improving the yield of crops.

[0043] The bent edge 47 in the scheme is matched with the covering groove, and the hinge part 42 and the contact pad 43 form a half-enclosed structure, thereby reducing the amount of crops required, reducing the production cost of the product, and facilitating the assembly of the product.

[0044] The bent edge 47 and the mounting part 46 form a U-shaped cavity, which can increase the structural strength of the mounting part 46, increase the setting stability of the mounting part 46, and enable it to bear a greater weight.

[0046] The second mounting hole 49 is arranged on the filling part, and the filling part on the contact pad 43 is more thick in the scheme. Therefore, arranging the second mounting hole 49 in the filling part can greatly improve the connection stability of the connecting part 44 to the hinge part 42 and the contact pad 43.

[0047] The filling part is provided with a rounded corner near the hinge part 45. The rounded corner can prevent the sharp corners from colliding with crops and causing damage to the crops. At the same time, the rounded corner can relatively reduce the amount of crops used, thereby reducing the production cost of the equipment. The contact pad 43 can be processed by pouring, thereby more efficiently completing the production of the equipment.

[0048] The hinge part 42 in the sweep chain group 4 can be integrally and quickly stamped by stamping, thereby ensuring the installation and connection strength of the hinge part 42 and reducing the production cost of the equipment.
