[0002] With the significant improvement of the global agricultural mechanization level, combine harvesters play a crucial role in increasing production and reducing costs. However, driven by technological innovation and market diversification, the harvesting scenarios faced by agricultural machinery operators are becoming increasingly complex. This trend forces harvesting machinery to have stronger adaptability and efficiency to meet the operating requirements under different crops, terrains, and climate conditions.
[0003] Especially in specific regions, such as in areas with complex farmland environments and crops like corn, the entanglement and accumulation problems of long straws and weeds during the harvesting process become particularly prominent. The accumulation of long straws and weeds not only leads to an increased workload due to blockage in the overbridge part, thereby affecting the overall harvesting efficiency, but also significantly increases the cleaning difficulty of the overbridge. The accumulation of long straws and weeds poses a substantial threat to the normal operation of harvesting machinery, especially in the case where ears of corn fall from the cutting table, which is mainly closely related to factors such as cutting table design, crop characteristics, and their maturity. For example, due to the excessive length of corn straws in some areas, some straws and weeds fall into the overbridge, causing the accumulation of weeds and stalks, and there is a phenomenon that ears of corn jump out of the cutting table at the auger. Such a situation will affect the harvesting efficiency and quality. Summary of the Utility Model

[0035] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0036] Example 1
[0037] According to the background technology, excessive accumulation of weeds and stems not only increases the cleaning burden of the bridge, but also poses a potential risk to the normal operation of the harvesting platform 2, resulting in the inability to effectively collect the fruit ears, thereby affecting the quality and efficiency of the final crop harvest. The continuous evolution of harvesting machinery technology is focusing on solving the technical challenges brought by complex harvesting environments, aiming to improve the adaptability of machinery, optimize the crop residue treatment process, and enhance the efficiency of the fruit ear collection system to ensure efficient and stable crop harvesting tasks in a changing agricultural environment.
[0038] Reference Figures 1 - 4, this embodiment provides a material blocking mechanism for the feeding inlet of the cutting table. There is an upper crossbeam 3 above the cutting table 2. The length direction of the crossbeam itself, which is also the width direction of the cutting table 2, is horizontal. A material blocking plate 1 is arranged on the upper crossbeam 3, and the material blocking plate 1 is arranged corresponding to the feeding inlet of the cutting table. The material blocking plate 1 is used to block materials such as broken stalks and weeds from falling into the cross-over and causing accumulation at the cross-over assembly.
[0039] Specifically, the material blocking plate 1 is connected to the upper crossbeam 3 through an angle adjustment structure 4, and the angle adjustment structure 4 is used to adjust the included angle between the material blocking plate 1 and the upper crossbeam 3.
[0040] In this embodiment, the angle adjustment structures 4 are respectively arranged at the opposite ends of the material blocking plate 1, and the material blocking plate 1 realizes angle flipping through the combined action of the angle adjustment structures 4 at both ends.
[0041] The angle adjustment structure 4 includes a connecting plate 401, a fixing plate 402 and a fastening assembly 403;
[0042] The connecting plate 401 is arranged at the end of the material blocking plate 1. The connecting plate 401 is provided with a first mounting hole 4011 and a second mounting hole 4012. The second mounting hole 4012 is a long hole and is located above the first mounting hole 4011; the second mounting hole 4012 can be a waist-shaped long hole or an arc-shaped long hole.
[0043] The fixing plate 402 is fixedly arranged on the upper crossbeam 3, and the fixing plate 402 is respectively provided with a third mounting hole and a fourth mounting hole. The first mounting hole 4011 and the third mounting hole, as well as the second mounting hole 4012 and the fourth mounting hole, are respectively assembled with the fastening assembly 403. The fastening assembly 403 can tightly connect the fixing plate 402 and the connecting plate 401.
[0044] In this embodiment, the first mounting hole 4011, the third mounting hole and the fourth mounting hole are respectively circular through holes, and the fastening assembly 403 adopts a bolt assembly. The bolt assembly includes a matching bolt and nut. That is, the connecting plate 401 and the fixing plate 402 are fixedly connected through two groups of bolt assemblies. When the angle of the material blocking plate 1 needs to be adjusted, the two groups of bolt assemblies at both ends are respectively loosened. Taking the bolt below as the rotation axis, the material blocking plate 1 can rotate around it. At the same time, the bolt above moves in the second mounting hole 4012. Through this method, the material blocking plate 1 can be adjusted within a certain angle, and different installation angles can be assembled according to different operating conditions. After the angle of the material blocking plate 1 is adjusted, all nuts can be tightened again to fix it.
[0045] In this embodiment, the baffle plate 1 is an arc-shaped plate, and a plurality of slender weight-reducing holes are provided on the baffle plate 1 to form a mesh plate. As Figure 1 and Figure 3 shown, these slender weight-reducing holes not only do not affect the blocking effect on the stems and weeds, but also can greatly reduce the self-weight and achieve lightweight design.
[0046] The baffle plate 1 is made of plastic material, or the baffle plate 1 is made of sheet metal.
[0047] Preferably, in order to improve the durability and service life, the baffle plate 1 is made of sheet metal and adopts a mesh sheet metal structure, which greatly reduces the weight while realizing the function. The top of the baffle plate 1 is bent to form the function of a reinforcing rib to improve the structural strength.
[0048] The connecting plates 401 on both sides are respectively welded and fixed to both ends of the baffle plate 1. The connecting plates 401 are also arc-shaped plates and have the same curvature as the baffle plate 1.
[0049] It should be noted that the width of the baffle plate 1 is not less than the width of the cutting table feeding inlet and not greater than the width of the cutting table 2 to ensure that the baffle plate 1 can cover the entire feeding inlet and block weeds to the greatest extent.
[0050] Embodiment 2
[0051] This embodiment provides a baffle mechanism for the cutting table feeding inlet. The difference from Embodiment 1 is that in this embodiment, both the third mounting hole and the fourth mounting hole are threaded holes, and the first mounting hole 4011 is a circular through hole. A bolt is first passed through the first mounting hole 4011 and then through the third mounting hole, and the external thread of this bolt is threadedly connected and fixed with the internal thread of the third mounting hole; then another bolt is passed through the second mounting hole 4012 and the fourth mounting hole in sequence, and the external thread of this bolt is threadedly connected and fixed with the internal thread of the fourth mounting hole.
[0052] Alternatively, the first mounting hole 4011 and the fourth mounting hole are threaded holes, the third mounting hole is a circular through hole, and the fastening component 403 is a bolt. The first bolt is passed through the third mounting hole and the first mounting hole 4011 in sequence, and the external thread of this bolt is threadedly connected and fixed with the internal thread of the first mounting hole 4011; then another bolt is passed through the second mounting hole 4012 and the fourth mounting hole in sequence, and the external thread of this bolt is threadedly connected and fixed with the internal thread of the fourth mounting hole.
