[0002] At present, there is a large amount of arable land in China, and corn is widely planted as an important species. With the development of agricultural mechanization, the planting and harvesting of corn has basically realized mechanical automation. Due to cost constraints, the most widely used corn harvester is combined harvesting The equipment is assembled on the tractor for use, and can be disassembled when not in use, so that the tractor can perform other tasks. The header of the harvester is at a certain angle to the ground during normal harvesting. The height of the front end of the high harvester header, the existing height adjustment method is to rotate the header by adjusting the shaft of the header, so that the height of the front end of the header is raised, but this adjustment method changes the distance between the header and the ground. The included angle affects the normal work of the header and reduces the working efficiency of the header

Embodiment Construction
[0010] Such as figure 1 and figure 2 As shown, a corn harvester header that can be lifted as a whole includes a harvesting platform 3 driven by a tractor wheel 1 through a belt 2, and also includes a lifting frame 4 and a fixed frame 5. The harvesting platform 3 is arranged on the left side of the lifting frame 4 , the front and rear sides of the lifting frame 4 are vertically arranged parallelogram supports, the four sides of the parallelogram supports are hinged in turn, and the parallelogram supports are provided with hydraulic rods 8 respectively hinged with the upper cross bar 6 and the right column 7, and the fixed frame 5 It is fixedly connected with the inner side of the upright column 7 on the right side of the lifting frame 4. The fixed frame 5 is set on the front support frame 9 of the tractor, and is fixed by pressing the front support frame 9 with the bolts 10 on the upper and lower end faces of the fixed frame 5. The right end of the fixed frame 5 A screw rod 1...
