AI Technical Summary

Technical Problem

Existing industrial hemp bundling machines suffer from complex mechanical transmission structures, high failure rates, and low operating efficiency. Furthermore, the lack of effective bundling machinery leads to increased bundling costs.

Method used

It adopts a tracked structure and hydraulic system, including a tracked self-propelled chassis, a picking mechanism, a hemp conveying mechanism, a hemp bundling mechanism, and a laying mechanism. It uses hydraulic motors and multi-way directional valves to achieve independent stepless speed regulation, eliminating the mechanical transmission mechanism. Combined with the automatic adjustment of a double variable pump and servo valve, it realizes continuous operation of picking, conveying, bundling, and laying.

Benefits of technology

It enables continuous operation of picking, conveying, bundling and laying, with simple structure, low failure rate, convenient use and maintenance, wide speed range, reasonable power matching, high efficiency, and improved stability and reliability of hydraulic system.
