A control method and system for an excavator to quickly switch between digging and dumping modes

Abstract

The invention discloses a control method and system for rapidly switching a soil excavating mode and a soil throwing mode of an excavator. The control method comprises the steps that respective action response speeds of the soil excavating mode and the soil throwing mode are set in advance; a vehicle controller detects whether a soil throwing mode signal exists or not, if no, the vehicle controller does not output a control signal, and if the soil throwing mode signal exists, a pilot pressure signal is detected; and if only bucket rod and scraper pan pressure signals are detected, and other pressure signals do not exist, the action response speed of the soil throwing mode is increased, and otherwise, the vehicle controller does not output the control signal. Through the control method for rapidly switching the soil excavating mode and the soil throwing mode of the excavator, a manipulator can rapidly select between the soil excavating mode and the soil throwing mode to meet different operation requirements.

Description

technical field [0001] The invention relates to the technical field of excavator excavation and dumping control technology, in particular to a control method and system for quickly switching digging and dumping modes of an excavator. Background technique [0002] With the improvement of the electronic control level of the current excavator industry, the matching degree of the compound action of the excavator is getting higher and higher, and the action is more and more comfortable and soft. But at the same time, there are differences in the operating habits of different excavator operators, and the softer and softer movements of the excavator will cause some operations to be impossible. For example, when an excavator operator wants to throw soil under the crawler belt, the stick is required to be quickly recovered and stopped quickly, so that the soil in the bucket can be thrown out due to inertia. If the stick action is too gentle, the soil will stay in the bucket, but if ...

AI Technical Summary

Problems solved by technology

If the action of the stick is too gentle, the soil will stay in the bucket, but if the stick reacts too quickly, it will cause the excavator to shake during normal digging, and it is easy to spill the soil in the bucket

If you want to satisfy the soil dumping, you have to sacrifice the softness of the excavator's movements, and the balance between the two is difficult to grasp
