Description

Technical Field

[0001] This utility model relates to the field of harvester brackets, specifically a harvester bracket welding assembly. Background Technology

[0002] The header support of a harvester is the main frame of the independent header and the mounting platform for various mechanisms of the header. Its design has an important impact on the stability and working efficiency of the harvester. Although the longitudinal dimension of the header support is relatively large, its working stability is good. It can provide a reliable mounting foundation for various mechanisms of the header and ensure that each component maintains a relatively stable position and movement during the harvesting operation.

[0003] However, most traditional harvester header support welded assemblies lack convenient connection structures and measures, making it difficult to quickly disassemble and assemble header support welded assemblies of multiple harvesters. As a result, the header width may need to be adjusted for different plots or crop types (such as rice and wheat harvesting). If the supports cannot be spliced, multiple repetitive operations are required or multiple sizes of complete header supports need to be stocked, affecting harvesting efficiency and cost. Utility Model Content

[0004] To address the shortcomings of existing technologies, most traditional harvester header support welded assemblies lack convenient connection structures and measures, making it difficult to quickly disassemble and assemble header support welded assemblies of multiple harvesters. This may require adjusting the header width for different plots or crop types. If the supports cannot be spliced, multiple repetitive operations or stockpiling of complete header supports of various sizes are necessary, affecting harvesting efficiency and cost. This utility model proposes a harvester support welded assembly.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a harvester bracket welding assembly, including a base frame, a connecting plate fixedly connected to one side of the base frame, and a side plate fixedly connected to the inner wall of the base frame. There are two side plates, and each side plate has a mounting hole on one side. The inner wall of the mounting hole is provided with a connecting structure.

[0006] The connecting structure includes a connecting cylinder, the surface of which is rotatably connected to the inner wall of the mounting hole. A mating plate is fixedly connected to one side of the connecting cylinder. A claw is fixedly connected to the surface of the mating plate. A protrusion is fixedly connected to the surface of the mating plate. The inner cavity of the claw engages with the surface of the protrusion. An avoidance hole is provided on one side of the connecting cylinder.

[0007] Preferably, a positioning plate is fixedly connected to the other side of the connecting cylinder, one side of the positioning plate is attached to one side of the side plate, and a first positioning hole is opened on one side of the positioning plate, and the number of the first positioning holes is multiple.

[0008] Preferably, a second positioning hole is provided on one side of the side plate. There are multiple second positioning holes, and the inner walls of the multiple second positioning holes are respectively connected to the inner walls of the corresponding first positioning holes. Fixing bolts are inserted into the inner walls of the second positioning holes and the inner walls of the first positioning holes.

[0009] Preferably, one side of the side plate has four reinforcement holes, and the inner wall of each reinforcement hole is provided with a reinforcement member.

[0010] Preferably, the reinforcing member includes a connecting rod, the surface of which is inserted into the inner wall of the reinforcing hole, and a foot is fixedly connected to the surface of the connecting rod. There are multiple feet, and the other end of each foot abuts against one side of the side plate. A fixing cap is threaded onto the surface of the connecting rod.

[0011] Preferably, a first welding plate is fixedly connected to one side of the base frame, and a cutting tooth is fixedly connected to one side of the first welding plate, wherein the number of cutting teeth is several.

[0012] Preferably, a second welding plate is fixedly connected to one side of the side plate, a dividing plate is fixedly connected to one side of the second welding plate, and a rake bracket is fixedly connected to the other side of the second welding plate.

[0013] The advantages of this utility model are:

[0014] In this invention, the connecting structure is rotatably installed in the mounting holes of the side plate via a connecting cylinder. The mating discs in each set of harvester brackets fit together. One set of mating discs rotates, which drives the corresponding claws and protrusions to rotate simultaneously. The rotating claws engage with the protrusions of another set, and the rotating protrusions engage with the claws of another set, forming a mutual engagement between the two sets of connecting structures. This allows for the rapid connection of the two sets of harvester brackets. The clearance holes facilitate the subsequent installation of the shaft structure, thus making the welded assembly of the harvester bracket modular. Multiple harvester brackets can be quickly connected through the connecting structure, adapting to different site conditions. This solves the problem that most traditional harvester header bracket welded assemblies lack convenient connection structures and measures, making it difficult to quickly disassemble and assemble multiple harvester header bracket welded assemblies. This may require adjusting the header width for different plots or crop types. If the brackets cannot be spliced, multiple repetitive operations or stockpiling of complete header brackets of various sizes are necessary, affecting harvesting efficiency and cost.

There are two side plates 3, and each side plate 3 has a mounting hole 4 on one side. The inner wall of the mounting hole 4 is provided with a connecting structure 5.

[0026] The connecting structure 5 includes a connecting cylinder 501, the surface of which is rotatably connected to the inner wall of the mounting hole 4. A mating plate 502 is fixedly connected to one side of the connecting cylinder 501, a claw 503 is fixedly connected to the surface of the mating plate 502, and a protrusion 504 is fixedly connected to the surface of the mating plate 502. The inner cavity of the claw 503 engages with the surface of the protrusion 504. An clearance hole 505 is provided on one side of the connecting cylinder 501. The harvester bracket welded assembly base frame 1 is the main supporting component. Two sets of side plates 3 are fixedly connected to one side of the inner wall of the base frame 1 by welding, and a connecting plate 2 is fixedly connected to the other side of the base frame 1 to form the main frame of the header bracket. The connecting plate 2 is used to connect with the harvester. The connecting structure 5 is connected through the connecting cylinder 501. The mounting holes 4 on the side plate 3 are rotatably installed. The connecting plates 502 in each set of harvester brackets are in contact with each other. One set of connecting plates 502 rotates, which drives the corresponding claws 503 and protrusions 504 to rotate simultaneously. The rotating claws 503 engage with the protrusions 504 of another set, and the rotating protrusions 504 engage with the claws 503 of another set, forming the mutual engagement of two sets of connecting structures 5. This allows for the quick connection of two sets of harvester brackets. The clearance holes 505 facilitate the subsequent installation of the shaft structure. Thus, the welding assembly of the harvester bracket is modular. Multiple harvester brackets can be quickly connected through the connecting structures 5 to adapt to different sites.

[0030] Working principle: The connecting plate 2 is used to connect with the harvester. The connecting structure 5 is rotatably installed in the mounting hole 4 of the side plate 3 through the connecting cylinder 501. The docking plates 502 in each set of harvester brackets are mutually engaged. One set of docking plates 502 rotates, which drives the corresponding claws 503 and protrusions 504 to rotate simultaneously. The rotating claws 503 engage with the protrusions 504 of the other set, and the rotating protrusions 504 engage with the claws 503 of the other set, forming mutual engagement of the two sets of connecting structures 5. This allows for the rapid connection of the two sets of harvester brackets. The positioning plate 6 is fixedly connected to the other side of the connecting cylinder 501. On the one hand, it can limit the position of the connecting cylinder 501. On the other hand, the first positioning hole 7 on the positioning plate 6 and the second positioning hole 8 on the side plate 3 correspond to each other. They can be fixed by the fixing bolt 9. The positioning plate 6 and the connecting structure 5 are fixed to the side plate 3 to prevent accidental rotation of the connecting structure 5 from causing the harvester brackets to detach. The two sets of harvester brackets are reinforced at four points by the reinforcement 11. The connecting rod 1101 in the reinforcement 11 is inserted into the corresponding two sets of reinforcement holes 10. The support foot 1102 on the surface of the connecting rod 1101 can abut against one side of the side plate 3 to improve the stability of the connecting rod 1101. Threaded grooves are opened on both ends of the connecting rod 1101. The fixing cap 1103 can be threaded onto the surface of the connecting rod 1101 until it fits against the side plate 3, improving the firmness of the connection between the connecting rod 1101 and the side plate 3. Thus, the welding assembly of the harvester bracket is modular. Multiple harvester brackets can be quickly connected through the connecting structure 5 to adapt to different sites.
