[0002] As an important oilseed crop in my country, rapeseed has long suffered from insufficient adaptability to mechanized harvesting. Traditional rapeseed harvesters use a fixed front shovel design, and their working width is limited to a single size specification at the factory.

[0003] In actual field operations, due to factors such as irregular plot shapes and varying planting row spacing, the width of the area to be harvested in the last pass often exceeds the effective working range of the front shovel. In this case, operators have to perform two repeated harvests: during the first harvest, the front shovel cannot completely cover the remaining crop strip, requiring a second adjustment of the trajectory to complete the remaining part. This working mode not only increases fuel consumption but also causes soil compaction due to repeated mechanical compaction, affecting subsequent crop planting. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 5 As shown, this application provides a rapeseed harvester, including: a harvester body 100, comprising a harvesting hopper 10, a drive mechanism 20, a transmission mechanism 30, a header 40, a rake 60, and a conveying channel 70. The drive mechanism 20 is located behind the harvesting hopper 10, and the output end of the drive mechanism 20 is connected to the transmission mechanism 30. The header 40 is located at the front end of the harvesting hopper 10. A front shovel dividing adjustment assembly 50 is disposed on both sides of the harvesting hopper 10, including a divider 5. 1. A connecting frame 52 is provided on one side of the divider 51. A locking post 53, an auxiliary block 55 and an adjusting rod 56 are provided on one side of the connecting frame 52. A locking hole 54 is provided on the outer side of the harvester hopper 10. A guide groove 57 is provided inside the adjusting rod 56. A connecting block 58 is provided at the bottom of the harvester hopper 10. A guide rod 59 is provided on one side of the connecting block 58. A linkage block 510 is provided on one side of the adjusting rod 56. A telescopic cylinder 511 is installed on one side of the linkage block 510.

[0028] After adopting the above technical solution, since the front shovel dividing adjustment component 50 is set on both sides of the harvester hopper 10, when adjusting the width of the divider 51, the front shovel dividing adjustment component 50 can move the divider 51 to increase the width between the two dividers 51. This solves the problem that in actual field operations, due to factors such as irregular plot shapes and differences in planting row spacing, the width of the last harvesting area often exceeds the effective working range of the front shovel. At this time, the operator has to perform two repeated harvests: during the first harvest, the front shovel cannot completely cover the remaining crop strip, and the remaining part needs to be completed by adjusting the travel trajectory a second time. This working mode not only increases fuel consumption, but also causes soil compaction due to repeated mechanical compaction, which affects the subsequent planting of crops.

[0029] It should be noted that when the width of the divider 51 is increased, under the support of the connecting block 58, the output end of the telescopic cylinder 511 is controlled to move the linkage block 510, which in turn moves the adjusting rod 56 outward. At the same time, the guide groove 57 slides along the outside of the guide rod 59. Then, the adjusting rod 56 moves the connecting frame 52 and the divider 51. During the movement of the connecting frame 52, the locking post 53 moves outward along the inside of the locking hole 54, thereby moving the two dividers 51 outward and widening the length of the harvesting hopper 10. At this time, the auxiliary block 55 is locked in the middle of the harvesting hopper 10 and the connecting frame 52, so that the rapeseed can be smoothly guided into the inside of the header 40, thereby widening the harvesting area of ​​the harvester.

[0030] In an optional embodiment, a lifting bracket is installed between the harvester hopper 10 and the rake 60, and the rake 60 is connected to the output end of the transmission mechanism 30, so that the rake 60 can be driven to rotate and rake the rapeseed towards the cutting platform 40, which facilitates the cutting of the rapeseed.

[0031] In an optional embodiment, the conveying channel 70 is connected to the harvesting hopper 10. The harvesting hopper 10 is equipped with a spiral feeding roller, which can transport the cut rapeseed to the connection between the conveying channel 70 and the harvesting hopper 10, and then transport it by the conveyor belt 80.

[0032] In an optional embodiment, a conveyor belt 80 is installed inside the conveying channel 70, and the end of the conveyor belt 80 is located at the connection between the conveying channel 70 and the harvesting hopper 10, so as to convey rapeseed.

[0033] In one optional embodiment, there are two sets of dividers 51 that are symmetrically distributed. The dividers 51 are connected to the connecting frame 52 by bolts. The connecting frame 52 is fixedly connected to the locking post 53. When the locking post 53 and the connecting frame 52 are positioned, the locking post 53 is inserted into the locking hole 54 to position the dividers 51 and the connecting frame 52.

[0034] In an optional embodiment, the auxiliary block 55 and the connecting frame 52 are an integral structure, and the connection between the two is provided with rounded corners. When the divider 51 is adjusted in width, the rapeseed can be moved to the middle of the harvesting hopper 10 by the action of the auxiliary block 55 and the rounded corners, and then cut by the header 40, so as to avoid the rapeseed from getting stuck at the connection between the connecting frame 52 and the harvesting hopper 10.

[0035] In an optional embodiment, the adjusting rod 56 and the connecting frame 52 are an integral structure, the connecting block 58 and the harvesting hopper 10 are an integral structure, and the guide rod 59 and the guide groove 57 are adapted to each other. When the width of the divider 51 is adjusted, the adjusting rod 56 can slide along the outside of the guide rod 59 to ensure the stability of the connecting frame 52 and the divider 51 during the movement process.

[0036] In an optional embodiment, the linkage block 510 and the adjusting rod 56 are fixedly connected. The two ends of the telescopic cylinder 511 are connected to the linkage block 510 and the connecting block 58 respectively. Under the support of the linkage block 510 and the connecting block 58, the linkage block 510 and the adjusting rod 56 can be moved outward, thereby causing the connecting frame 52 and the divider 51 to move outward, thus widening the harvesting area of ​​the harvester.
