AI Technical Summary
Technical Problem
Existing milling machines face inefficiencies due to the automatic tilt control system's inability to adjust the cover plate or anti-slip device when they catch on the ground, leading to hydraulic pressure imbalances and impaired drive and leveling performance.
Method used
A system that includes sensors to detect ground pressure and automatically raises or pulses the cover plate or anti-slip device to resolve blockage events, ensuring the milling machine maintains optimal operational conditions.
Benefits of technology
The system effectively addresses blockage issues by adjusting the cover plate or anti-slip device, preventing hydraulic pressure imbalances and maintaining efficient milling operations.

Abstract
A milling machine (10) comprises a frame (12) mounted on at least one height-adjustable leg (24, 26). A sensor (32) is connected to the at least one leg and configured to detect the ground pressure exerted by the leg on a ground surface. The milling machine (10) has a rotor chamber (38) with a movable cover plate (64) and a movable anti-slip device (44). A control unit (30) is configured to determine, based on the ground pressure information, whether the ground pressure exerted by the leg (24, 26) is below a predetermined value that indicates a blocking event.The control unit (30) is configured to automatically raise or pulsate at least one of the two elements, namely the cover plate (64) or the anti-slip device (44), to clear the blocking event, based on the finding that the ground pressure generated by the at least one leg (24, 26) is below a predetermined value.
