A restraining traction rope 3-21 is provided between two adjacent rope blocks 3-20. Figure 3 As shown, when the two connecting rods 3-15 are pulled out from the two connecting holes 3-14, the rear cargo door panel 3-6 will flip downwards, and the two limiting traction ropes 3-21 will be stretched until the rear cargo door panel 3-6 is parallel to the loading floor 3-2. At this time, the cargo length of the entire cargo compartment can be increased, so that the rear cargo door panel 3-6 can be flush with the loading floor 3-2, thereby extending the usable cargo length of the cargo compartment.

[0020] The front bottom of the tractor unit 1 is equipped with an electric winch 1-6 and a tow hook 1-7, which can facilitate the extrication of the loader when it gets stuck in the mud or breaks down, and also provide the ability to tow trailers or help other vehicles get out of trouble.

[0021] When using this utility model: When the agricultural loader is traveling on a flat road, only the rear drive motor 3-17 needs to be started for rear-wheel drive. On a muddy or rugged road, the front drive motor 1-4 can be started simultaneously to achieve dual-drive four-wheel travel. If a tire gets stuck, it can be freed with the help of external force through the electric winch 1-6 and the tow hook 1-7. When the battery box 2-5 cannot provide power to the motor, the batteries in the two battery boxes 2-5 can be charged through the on-board charger 2-7. When the loader needs to load cargo, the connecting rod 3-15 is released, and the rear cargo door 3-5 flips down and is parallel to the loading floor under the action of the restraining towing rope 3-21. When it is necessary to unload cargo, the fixed connecting rods on the left and right sides can be released, so that the left cargo door 3-4 and the right cargo door 3-5 can be flipped down and opened. The tools used in the work can be placed on the tool rack 2-8.
