Description

Technical Field

[0001] This application relates to the field of agricultural machinery and equipment technology, and more particularly to a harvester with a rotatable shredder and a harvesting system. Background Technology

[0002] As a component of combine harvesters, the shredder is typically fixed to the combine harvester body with bolts in existing technology, and serves to shred the straw.

[0003] Among cross-regional operators, the users they serve are wide-ranging and their needs for straw processing vary. Some require straw shredding, while others do not. This necessitates operators constantly disassembling and reassembling the shredder. Due to the shredder's weight, it cannot be disassembled by a single person; at least three to four people are required. This leads to reduced work efficiency and increased labor costs. Furthermore, the disassembled shredder does not travel with the combine harvester and must be returned to its storage location when it needs to be reinstalled, further reducing work efficiency.

[0049] Example 1

[0050] This application provides a harvester including a shredder 5, which can be in a working state under certain working conditions to shred straw; and in an idle state, i.e., a non-shredding state, under certain working conditions, the shredder 5 is tilted upwards; regardless of whether it is in a working state or an idle state, the shredder 5 is located on the main body 7 of the harvester and moves with the harvester. The following is in conjunction with... Figures 1-3 As shown, this application provides a detailed description of a harvester with a reversible shredder.

[0051] In this embodiment, combined with Figure 1 As shown, the harvester includes a body 7, a lifting assembly, and a shredder 5.

[0052] The lifting assembly includes a motor 2 as a drive mechanism and a steel wire rope 201. The motor 2 is mounted on a drum cover 1 on the top of the machine body 1. The output end of the motor 2 is connected to a winding drum, and the steel wire rope 201 is wound around the winding drum.

[0053] A support base 3 is provided in the middle of the machine body 7. An upward rotating shaft 4 arranged in the horizontal direction is provided on the support base 3. The two ends of the shredder 5 are connected to the upward rotating shaft 4 and can rotate relative to the support base 3.

[0054] The motor 2 is connected to the chopper 5 via a steel wire rope 201. The rotation of the motor 2 causes the steel wire rope 201 to extend or retract, thereby causing the chopper 5 to rotate around the upward rotating shaft 4, thus realizing the switching between the working state and the upward state of the chopper 5.

[0055] To facilitate the installation of the motor 2, preferably, a motor mounting base 101 is provided at the edge of the roller cover 1, and the motor 2 is mounted on the motor mounting base 101.

[0056] To facilitate the connection between the wire rope 201 and the chopper 5, a lifting ring 501 is provided on the chopper 5, and a hook is provided at the free end of the wire rope 201. By connecting the hook with the lifting ring 5, the motor 2 can drive the chopper 5 to rotate upward around the upward rotating shaft 4.

[0057] The way the hook and the lifting ring 5 are matched is simple and easy to operate, convenient to disassemble and assemble, and the connection is firm.

[0058] In a preferred embodiment, multiple lifting rings 501 can be arranged side by side on the chopper 5, and the ends of the wire rope 201 can be branched into a corresponding number of sub-ropes, which are connected to each lifting ring 501 through hooks, so that the lifting force can be applied to the chopper 5 more evenly, and the turning process is more stable and safe.

[0059] It is worth noting that in this embodiment, a motor 2 is used as the drive structure, but this application is not limited to the above structure and can also be a cylinder structure.

[0060] In other embodiments, the lifting ring 501 on the shredder 5 can be replaced with a plug, and the free end of the wire rope 201 is connected to a buckle, which can be detachably plugged into the plug, thereby realizing the connection between the wire rope 201 and the shredder 5.

[0061] In a preferred embodiment, hook points are provided on one or both sides of the body 7 and the shredder 5, and then a pull rod 8 is provided, with hooks at both ends of the pull rod 8 that can be connected to the hook points.

[0062] When the shredder 5 is in the upward-tilted state, it is connected to the machine body 7 and the shredder 5 respectively by the pull rod 8, so that the relative position between the machine body 7 and the shredder 5 remains unchanged. At the same time, it can reduce the force on the wire rope 201, thereby protecting the motor 2.

[0063] In a preferred embodiment, a side-tilting rotating shaft 6 is provided on one side of the machine body 7 near the support base 3; a first mounting bracket 401 and a second mounting bracket 402 are respectively provided on both sides of the shredder 5.

[0064] The first mounting bracket 401 is mounted on the side-tilting rotating shaft 6, enabling the shredder 5 to rotate around the side-tilting rotating shaft 6 and switch the shredder 5 between the working state and the side-tilting state.

[0065] The second mounting bracket 402 can be detachably connected to the support base 3 or the machine body 7. The connection method can be bolt connection, pin connection, overlapping, etc., as long as it can maintain the stability of the shredder 5 and facilitate disassembly during operation.

[0066] When it is necessary to tilt to the side, the chopper 5 tilts to the side via the tilting rotating shaft 6, at which point the screen box 9 can be exposed for easy replacement or maintenance.

[0067] Preferably, both ends of the upward rotating shaft 4 can also be installed on the first mounting bracket 401 and the second mounting bracket 402 together, moving with the shredder 5. Meanwhile, the side rotating shaft 6 is set perpendicular to the upward rotating shaft 4.

[0068] This solution enables rapid switching between the chopper's working and tilted states. A further design allows for rapid switching between the working and tilted states. Furthermore, regardless of the chopper's current state, it moves with the vehicle and can be switched back to any other state at any time. The switching process is simple, quick, safe, and stable, requiring only one person to operate, thus saving manpower.
