[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The object of the present invention is to provide a combine harvester header with better adaptability and a combine harvester comprising the header.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] refer to Figure 1-Figure 8As shown, this embodiment provides a header for a combine harvester, comprising: a main body 1, a bridge, a mounting plate 5, a second linear telescopic device 9, two connecting plates 6 and two first linear telescopic devices 8. The main body 1 is the main part of the header, and a feed port 101 is provided on the main body 1, and the harvested wheat and straw enter the interior of the bridge from the feed port 101. The bridge comprises a bridge seat 2 and a bridge body 3, one end of the bridge seat 2 is arranged opposite to one end of the bridge body 3, the shapes of the opposite ends of the bridge seat 2 and the bridge body 3 match, and the bottoms of the opposite ends of the bridge seat 2 and the bridge body 3 are rotatably connected by a rotating shaft 4, when the opposite ends of the bridge seat 2 and the bridge body 3 are against each other, the circumferential edges of the opposite ends of the bridge seat 2 and the bridge body 3 are completely fitted, and a closed space is formed inside the bridge. The mounting plate 5 can be detachably mounted on the main body 1, and the main body 1 is mounted on the bridge through the mounting plate 5. A through hole 501 is provided at a position of the mounting plate 5 opposite to the feed port 101. Two arc-shaped protrusions 12 and two connecting columns 13 are provided on the mounting plate 5. Two connecting plates 6 are respectively arranged at the top and bottom of the bridge seat 2, and two arc-shaped grooves 601 are symmetrically provided on the two connecting plates 6. The shape of the arc-shaped grooves 601 matches the shape of the arc-shaped protrusions 12, and the two arc-shaped protrusions 12 can be rotatably arranged in the two arc-shaped grooves 601, respectively. The entrance of the bridge seat 2 is connected to the feed port 101 of the main body 1 through the through hole 501. Two first linear telescopic devices 8 are symmetrically arranged on both sides of the bridge, and one end of the two first linear telescopic devices 8 is respectively rotatably connected to the two connecting columns 13, and the other ends of the two first linear telescopic devices 8 are both hingedly connected to the bridge seat 2. The two ends of the second linear telescopic device 9 are respectively hingedly connected to the bridge body 3 and the connecting plate 6 arranged on the top of the bridge seat 2.

[0033] During specific use, when harvesting in plain areas, that is, on horizontal ground, there is no need to adjust the posture of the main body 1 of the harvesting platform. When harvesting mountainous or sloping land, the posture of the harvesting platform can be adjusted by telescoping the two first linear telescopic devices 8 and the second linear telescopic device 9, so that the main body 1 of the harvesting platform is as parallel to the ground as possible, so that the harvesting platform can adapt to the mountainous and sloping land. During adjustment, the first linear telescopic device 8 extends or retracts to drive the arc-shaped protrusion 12 to rotate in the arc-shaped groove 601 of the connecting plate 6. At the same time, the second linear telescopic device 9 extends or retracts to drive the mounting plate 5 to rotate a certain angle (depending on actual needs), so that the harvesting inclination angle of the main body 1 changes. With this arrangement, when harvesting lodged crops and crops at the bottom of the slope, the loss of grains from the harvesting platform can be reduced, while the working efficiency of the harvesting platform is improved, and the working efficiency and adaptability of the combine harvester are improved.

[0034] Specifically, in this embodiment, Figure 4-Figure 5 As shown, the axes of the two arc-shaped protrusions 12 coincide with each other, and the axes of the two arc-shaped protrusions 12 are perpendicular to the axis of the rotating shaft 4 , and each connecting column 13 is perpendicular to the mounting plate 5 .

[0035] In another embodiment of the present invention, a first buffer seal is provided on the circumferential edge of one end of the bridge seat 2 close to the bridge body 3, and a second buffer seal is provided on the circumferential edge of one end of the bridge body 3 close to the bridge seat 2. The first buffer seal and the second buffer seal play a buffering role, and at the same time, when the opposite ends of the bridge body 3 and the bridge seat 2 are against each other, the tightness of the sealing of the splicing position of the bridge body 3 and the bridge seat 2 is ensured. With such a configuration, when the main body 1 rotates relative to the bridge body 3, that is, when the bridge seat 2 rotates relative to the bridge body 3, an opening will be formed between the bridge seat 2 and the bridge body 3, but because the wheat grains are still attached to the straw when passing through the opening and are transported synchronously with the straw, the wheat grains will not escape from the inside of the bridge through the opening between the bridge seat 2 and the bridge body 3.

[0036] In another embodiment of the present invention, Figure 7 As shown, unlike the embodiment in which the circumferential edge of one end of the bridge seat 2 close to the bridge body 3 is provided with a first buffer seal, and the circumferential edge of one end of the bridge body 3 close to the bridge seat 2 is provided with a second buffer seal, in this embodiment, the circumferential edge of one end of the bridge seat 2 close to the bridge body 3 is not provided with a first buffer seal, and the circumferential edge of one end of the bridge body 3 close to the bridge seat 2 is not provided with a second buffer seal, but in this embodiment, the bridge also includes a flexible cover 17, and the opposite ends of the bridge seat 2 and the bridge body 3 are connected by the flexible cover 17. When the bridge seat 2 and the bridge body 3 rotate relative to each other, the flexible cover 17 can block the opening between the bridge seat 2 and the bridge body 3. When the opposite ends of the bridge seat 2 and the bridge body 3 are against each other, the flexible cover 17 is in a folded state. When the bridge seat 2 and the bridge body 3 rotate relative to each other, as the bridge seat 2 and the bridge body 3 move away from each other, the flexible cover 17 gradually opens. By providing the flexible cover 17, it is effectively prevented that wheat grains escape from the inside of the bridge through the opening between the bridge seat 2 and the bridge body 3.

[0037] In another embodiment of the present invention, Figure 2 As shown, the main body 1 is provided with a hook portion 10, the mounting plate 5 is provided with a hook 11, the hook 11 is hung on the hook portion 10, and the hook portion 10 and the hook 11 are connected by a positioning pin 16. Specifically, the hook portion 10 and the hook 11 are respectively provided with a first through hole and a second through hole, and the first through hole and the second through hole are located opposite to each other, and the positioning pin 16 is passed through the first through hole and the second through hole to realize the connection between the hook portion 10 and the hook 11 by the positioning pin 16.

[0038] In another embodiment of the present invention, Figure 1As shown, the harvester header also includes two limit plates 14, and an arc groove 1201 is provided on the side wall of the arc protrusion 12. The two limit plates 14 correspond to and are connected to the two connecting plates 6 one by one, and each limit plate 14 is arranged between the mounting plate 5 and the connecting plate 6. One end of each limit plate 14 close to the arc groove 1201 is arranged in the arc groove 1201, and one end of each limit plate 14 close to the arc groove 1201 matches the shape of the arc groove 1201, so that the limit plate 14 and the arc protrusion 12 can rotate relative to each other. The two limit plates 14 are used to clamp the two arc protrusions 12 to prevent the mounting plate 5 from separating from the bridge seat 2.

[0039] In another embodiment of the present invention, the feed port 101, the through port 501 and the inlet of the bridge seat 2 are of the same shape, and the feed port 101, the through port 501 and the inlet are all irregular octagons. Figure 8 A feeding roller 7 is arranged inside the bridge, and the two ends of the feeding roller 7 are rotatably arranged on the two side walls of the bridge, and the feed port 101, the through port 501 and the inlet are arranged opposite to the feeding roller 7. The feeding roller 7 is used to transport the harvested materials on the main body 1 to the threshing device of the combine harvester. Fig. 9 As shown, the feed port of the existing combine harvester header body 3' is directly connected to the entrance of the bridge, and the feed port and the entrance are both rectangular in shape. In this embodiment, the feed port 101, the through port 501 and the entrance are all set to Figure 8 The reason for the irregular octagon shown is that when the main body 1 and the bridge rotate relative to each other, the feed port 101 and the through port 501 rotate relative to the inlet. After the rotation, the area of ​​the feed port 101 and the through port 501 relative to the inlet is the actual feed area 15, which is different from the actual feed area 15. Fig. 9 Compared with the rectangular shape shown in FIG. 1 , when the main body and the bridge rotate relative to each other, the embodiment Figure 8 The actual feed area 15 of the irregular octagonal shape shown is larger than Fig. 9 The actual feeding area 1' of the rectangular shape shown in the figure is set as the feeding port 101 in this embodiment. Figure 8 The irregular octagon shown feeds more smoothly and has higher feeding efficiency.

[0040] It should be noted that the shapes of the feed port 101, the through port 501 and the inlet are not limited to Figure 8 The irregular octagon shown can also be other shapes, as long as the main body 1 and the bridge can rotate relative to each other. Fig. 9 The rectangular shape shown allows for smoother feeding.

[0041] In another embodiment of the present invention, the first linear telescopic device 8 is a first hydraulic cylinder, and the second linear telescopic device 9 is a second hydraulic cylinder. It should be noted that the first linear telescopic device 8 is not limited to the first hydraulic cylinder, and the second linear telescopic device 9 is not limited to the second hydraulic cylinder. The first linear telescopic device 8 and the second linear telescopic device 9 can be other devices capable of achieving linear telescopic movement, which are only described by way of example.

[0042] In another embodiment of the present invention, a combine harvester is provided. The combine harvester includes the combine harvester header provided in any of the above embodiments.

[0043] The present specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
