AI Technical Summary

Technical Problem

Conventional agricultural conveyors face challenges in synchronizing with bulb harvesters, leading to crop misalignment, damage from impact, and increased waste during transport due to lack of real-time load detection and height adjustment, especially on uneven terrain.

Method used

An agricultural work vehicle equipped with a wire-based position tracking module and weight sensors to autonomously follow the harvester, adjust the loading base height based on load weight, and integrate camera recognition for precise path control, minimizing crop damage and ensuring stable transport.

Benefits of technology

The system enhances crop transport precision and efficiency by maintaining consistent drop height, reducing damage, and optimizing loading conditions, thereby minimizing economic losses and labor burden.

Abstract

According to one embodiment of the present invention, an agricultural work vehicle configured to load crops while autonomously following the rear of a harvester is provided, and an agricultural work vehicle having an automatic following function is provided, comprising a following control unit that controls a driving path by recognizing a relative position with respect to the harvester, a loading base for receiving crops falling from the harvester, a lifting control unit that automatically adjusts the height of the loading base according to the loading state of the crops, and a central control unit that controls the following control unit and the lifting control unit. According to the present invention, by predicting and correcting the time delay caused by the rotational movement of the harvester, the rotational response error between the harvester and the carrier is minimized, and a carrier capable of precisely following the trajectory of the harvester even in curved driving sections can be obtained.
