AI Technical Summary
The fruit box device of existing combine harvesters has a fixed unloading height, which is difficult to match with large agricultural transport vehicles. This results in the need to use loaders for secondary transfer, which reduces harvesting efficiency and increases operating costs.
The fruit box device is equipped with tilting cylinders, lifting cylinders, and tipping cylinders. The tilting and tipping of the fruit box is achieved through a hydraulic control system, and the unloading height can be adjusted autonomously to adapt to different truck bed heights.
It achieves autonomous control over the height of the fruit box, simplifies the unloading process, improves harvesting efficiency, reduces operating costs, and does not change the volume of the fruit box or the overall shape of the machine.
