AI Technical Summary

Benefits of technology

This patented technology uses an arrangement where multiple valves can be controlled simultaneously without overlapping pressures. It also includes a pressure equalization valve placed after each reversal valve, allowing for better control during operation. Additionally, there may have been some means to adjust the lift speeds based upon factors like machine power output. Overall, this design helps prevent damage from excessive pressure buildup while ensuring efficient performance across various types of machines with varying levels of efficiency.

Problems solved by technology

In summary, current methods for collecting crop plants such as corn have limitations due to their manual nature and lack of automated systems. These techniques involve heavy workforce effort and require significant human resources, leading to increased costs associated therewith.

Abstract

The invention relates to a hydraulic control system, in particular to a novel hydraulic control system for a combine harvester. The novel hydraulic control system for the combine harvester mainly solves the technical problems that when multiple valves are simultaneously operated by a hydraulic system of existing combine harvester operating mechanisms in the prior art, the largest output pressure of a pump can exceed the ultimate pressure which can be borne by the system, the hydraulic pump and pipelines are extremely prone to damage, the actual flow requirement differences of the operating mechanisms are large, a working pump always supplies full flow to each reversing valve, thus the flow requirements of the operating mechanisms can not be satisfied at the same time, and the controllability is poor. The novel hydraulic control system for the combine harvester is composed of a double-way slide valve, a straw shifting wheel one-way slide valve and a grain unloading one-way slide valve. The double-way slide valve is connected with a header cylinder, a left steering cylinder and a right steering cylinder through the pipelines. The straw shifting wheel one-way slide valve is connected with a straw shifting wheel cylinder through one pipeline. The grain unloading one-way slide valve is connected with a grain unloading cylinder through one pipeline. Oil return ports of the double-way slide valve, the straw shifting wheel one-way slide valve and the grain unloading one-way slide valve are connected in parallel.
