AI Technical Summary

Technical Problem

During the harvesting process, sugarcane harvesters are affected by uneven terrain, and the height of the cutting platform cannot automatically adapt to the terrain, resulting in low harvesting efficiency and high cutting loss rate. In addition, traditional manual adjustment is not timely or accurate, which affects the service life of the machine and the harvesting quality.

Method used

Design a test bench for adaptive adjustment of the header height of a sugarcane harvester. The test bench combines a lidar sensor and a hydraulic system. By scanning terrain data with lidar, the lifting and tilting devices are controlled to automatically adjust the height and angle of the header. Combined with the sugarcane conveying mechanism, the test bench simulates the actual growing environment and achieves adaptive adjustment of the header.

Benefits of technology

This improved the adaptability and working efficiency of sugarcane harvesters under different terrain conditions, ensured cutting accuracy and machine life, and obtained more accurate test data.

Abstract

The application discloses a sugarcane harvester header height self-adaptive adjustment test bench, and belongs to the technical field of agricultural machinery test benches, which comprises a gantry main frame, a cutting mechanism, a sugarcane conveying mechanism, a laser radar sensor and a control system. The cutting mechanism comprises a header box, a lifting device and an inclination device. The sugarcane conveying mechanism comprises a conveying device, a soil supporting box and a sugarcane fixing device. The laser radar sensor is arranged on the gantry main frame, is used for scanning the simulated sugarcane field ground undulation condition in the soil supporting box, and sends the scanned data to the control system. According to the received data, the control system controls the lifting device and the inclination device to perform corresponding actions, and self-adaptively adjusts the height and the inclination angle of the header box. The application can self-adaptively adjust the cutting height and the angle of the header according to the change of the terrain height, so as to improve the adaptability and the working efficiency of the sugarcane harvester under different terrain conditions.
