AI Technical Summary

Technical Problem

The existing automatic mud scraping devices of tracked harvesters have problems such as mud accumulation after scraping, secondary entanglement of support rollers, inaccurate sensor detection, and mechanical wear, which affect driving stability and operating efficiency.

Method used

Design an automatic sludge scraping device that includes a mounting base, a mudguard, a detector, a sludge scraping assembly, and a control assembly. The detector monitors the sludge accumulation height in real time, and the sludge scraping is achieved by using an electromagnet and an elastic element to drive the sludge scraping assembly. The sludge scraping process is controlled by a microcontroller and a relay.

Benefits of technology

It achieves precise scraping and efficient removal of silt, avoids secondary entanglement, reduces labor intensity and maintenance costs, and ensures the continuity of harvesting operations.
