Description

Technical Field

[0001] This utility model relates to the field of electrified agricultural machinery technology, and in particular to a quick-change mechanism for the chassis battery of a tracked agricultural robot. Background Technology

[0002] my country is a major agricultural country. Since the 2023 World Robot Conference, my country's robotics field has been combining automated machinery and equipment with traditional agriculture, developing towards highly intelligent robots.

[0003] Currently, tracked agricultural robots have transitioned from traditional fuel engines to pure electric models. However, due to limitations in the spatial layout and battery structure of tracked agricultural robots in the current market, the battery pack can only be stored in the middle of the vehicle body. This means that when repairing or replacing the battery, it is necessary to first disassemble the superstructure or frame beams and other components, which increases the workload of maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a quick-change mechanism for the chassis battery of a tracked agricultural robot, which aims to solve the problem of inconvenient battery removal in existing pure electric tracked agricultural robots.

[0005] To achieve the above objectives, this utility model provides a quick-change battery mechanism for a tracked agricultural robot chassis, including a chassis frame, multiple roller assemblies, multiple side wheel assemblies, multiple top wheel assemblies, and two limiting components. The multiple roller assemblies are all mounted on the chassis frame. The multiple side wheel assemblies are respectively fixedly connected to the chassis frame and located on the inner side of the chassis frame. The multiple top wheel assemblies are respectively fixedly connected to the chassis frame and located on the side of the chassis frame away from the roller assemblies. The two limiting components are respectively disposed at the tail end of the chassis frame.

[0006] The roller assembly includes a frame, multiple rotating rods, and multiple first rollers. The frame is fixedly connected to the chassis frame and is located on the chassis frame. The multiple rotating rods are rotatably connected to the frame and are all located on the frame. The multiple first rollers are fixedly connected to the multiple rotating rods and are located on the multiple rotating rods.

[0007] The side wheel assembly includes a vertical beam, a first adjusting bolt, and a second roller. The vertical beam is fixedly connected to the chassis frame and is located on the chassis frame. The first adjusting bolt is installed on the vertical beam, and the second roller is installed on one side of the first adjusting bolt.

[0008] The top wheel assembly includes a crossbeam, two second adjusting bolts, two connecting frames, two rotating shafts, and two third rollers. The crossbeam is fixedly connected to the chassis frame and located on the chassis frame. The two second adjusting bolts are respectively installed on the crossbeam. The two connecting frames are respectively installed on the two second adjusting bolts. The two rotating shafts are rotatably connected to the two connecting frames and are respectively located on the two connecting frames. The two third rollers are fixedly connected to the two rotating shafts and are respectively located on the two rotating shafts.

[0009] The limiting component includes a support frame, two screws and two knobs. The support frame is fixed to the chassis frame by the two screws, and the two knobs are fixedly connected to the two screws respectively and are located on the two screws respectively.

[0010] This utility model discloses a quick-change battery mechanism for a tracked agricultural robot chassis. The chassis frame provides installation conditions for multiple roller groups, multiple side wheel groups, multiple top wheel groups, and two limiting components. The multiple roller groups, side wheel groups, and top wheel groups reduce the friction when pulling out the battery pack, while the two limiting components hold and limit the battery pack. When it is necessary to disassemble the battery pack, the two limiting components are removed from the chassis in sequence, and the connector wires of the battery pack are disconnected. By holding the two auxiliary handles on the battery pack, the battery pack is pulled away from the chassis frame. The battery pack slides on the multiple roller groups, side wheel groups, and top wheel groups, reducing the friction when pulling the battery pack. Conversely, the battery pack can be installed, achieving quick assembly and disassembly of the battery pack. This solves the problem of inconvenient battery disassembly in existing pure electric tracked agricultural robots. Attached Figure Description
