Solution Overview

Problem

Existing methods for filling and compacting harvested crops in silos often result in uneven layer heights, leading to non-uniform compaction and inefficiencies in storage, as operators manually adjust the distribution vehicle's sliding plate to achieve uniformity.

Innovation Solution

A method using sensor devices on the distribution vehicle to continuously record the surface topography of the crop within the silo, processing this information to automatically control the working height of the sliding plate, ensuring each crop layer is stacked with a substantially uniform height, thereby optimizing compaction and filling processes.
