Description

Technical Field

[0001] This utility model relates to the field of cab wiring structure technology, and in particular to a cab wiring port structure, a cab, and agricultural machinery. Background Technology

[0002] The combine harvester cab is the operating center of the harvester. All core operations and controls of the harvester are concentrated in the cab, which also provides the driver with a safe, comfortable, and reliable working environment. With social progress and technological development, grain harvesters are evolving towards higher power, larger feeding capacity, and larger sizes. As the power and size of harvesters continue to increase, operators have higher requirements for cab comfort and sealing. Furthermore, with the improvement of relevant laws and regulations, the sound insulation and vibration damping levels of the cab have an increasingly significant impact on product quality and sales.

[0003] Because the core operation and control of the entire harvester are concentrated in the cab, the power supply and communication lines of the entire harvester are controlled by the controller inside the cab and transmitted to various mechanisms via lines. Therefore, all lines must pass through the cab before connecting to the electrical connectors of each functional mechanism. Currently, the power supply and communication lines in the harvester cab follow the principle of being as close as possible to the nearest point, resulting in many cable trays on the cab floor. Rubber cable loops are used to reduce the impact of these cable trays on the cab's sealing and sound insulation performance. As a result, the overall quietness and comfort of the cab have not reached a higher level, and the complexity of the cab's wiring layout has been indirectly increased.

[0004] The existing harvester cab cable passage openings are mainly concentrated on the floor and rear wall, which greatly affects the overall sealing of the cab. Conical rubber cable passage openings are used to reduce the impact of the openings.

[0005] Currently, the electrical power supply and communication lines in the harvester cab are routed by drilling wire holes at different locations on the floor or rear wall that match the rubber wire guide coils. This method largely compromises the cab's good sealing and sound insulation. Utility Model Content

[0062] The beneficial effects of adopting this utility model's technical solution are as follows: Given the limited space between the rear wall of the cab and the interior trim, the extension distance of the cable tray does not occupy interior cab space, avoiding insufficient installation space and the risk of electrical wiring being damaged due to excessively small bending angles. The cable tray integrates various wire harness connector mounting holes, allowing for easy modification based on changes in electrical wiring interfaces. Matching wire harness connector mounting holes are created on the cable tray according to the connector models of various power and communication lines of the harvester, ensuring that all power and communication line wire harness connector mounting holes are installed on the cable tray. This high integration improves assembly convenience, sealing reliability, and maintenance ease. The right rear side of the harvester cab's rear wall houses the grain tank support structure. The cable tray body is angled to relocate the maintenance area to the side of the cab, avoiding the grain tank support rod and facilitating maintenance.
