When the bottom plate 61 rotates around the hinge axis 63 with the frame 1, it drives the first flip wheel 71 to rotate axially and then drives the second flip that engages in sequence. The wheel 72 and the third flipping wheel 73 rotate, and the third flipping wheel 73 drives the limiting arm 74 to swing outward during the rotation, so that the tail plate 621 flips outwards under its own weight. In the above solution, when the first hydraulic cylinder 11 pushes the piston rod to flip the hopper 6 upward around the hinge, the bottom plate 61 drives the hinge shaft 63 hinged with the frame 1 to rotate, and the hinge shaft 63 drives the first flip wheel 71 to rotate. , the first flipping wheel 71 drives the second flipping wheel 72 meshed with it to rotate, the second flipping wheel 72 drives the third flipping wheel 73 meshed with it to rotate, and the third flipping wheel 73 drives the limiting arm 74 to swing during the rotation. During operation, when the hopper 6 is flipping upward around the hinge, the tail plate 621 gradually tilts outward. At the same time, the flip mechanism 7 drives the limit arm 74 to flip outward, causing the limit arm 74 to resist one end of the tail plate 621. It can be far away from the tail plate 621, and the inclined tail plate 621 will flip outward under the action of gravity, so the tail plate 621 will flip with the rotation of the hopper 6 until the tail plate 621 opens the rear end of the storage chamber, which is convenient The reeds in the storage cavity are quickly discharged.

The limiting arm 74 is arranged in an arc-shaped structure along its length direction. One end of the limiting arm 74 is fixedly connected to the rotation axis of the third flip wheel 73 that is rotatably connected to the rear end of the frame 1 , and the other end of the limiting arm 74 resists the outer wall of the tail plate 621 .

The third flipping wheel 73 is engaged, and a synchronous connecting rod 741 is connected between the two limiting arms 74 on the two third flipping wheels 73 . By arranging two sets of flipping wheels to synchronously drive the rotation of the limit arm 74, it is beneficial to reduce the load force when each flipping wheel engages and rotates, thereby improving the working stability of the flipping mechanism 7 and extending the service life of the flipping mechanism 7. .

Four of the six traveling wheels 2 are located at the front of the frame 1 as the front wheels 23 , and two of the traveling wheels 2 are located at the rear of the frame 1 as the rear wheels 24 . Since the header device in front of the harvester is heavy, and the cab is also located in front of the frame 1, in order to prevent the front of the harvester from being too heavy and prone to settling in the wetland, four driving wheels 2 are set on the frame 1 The front and sides make it difficult for the harvester to get stuck in the swamp.
