Technical Field

The invention relates to the field of excavator accessory equipment, in particular to an excavator accessory control system and a control method.

Background

The excavator is an indispensable common machine in the current engineering construction, the excavator can replace the bucket with other accessories to carry out special operation besides the excavation operation by utilizing the bucket, such as a breaking hammer, a vibration hammer, a hydraulic shear and the like, and when the excavator is used, the original bucket is detached, and the other accessories are replaced to carry out the operation.

The existing control system for replacing accessories is connected to a hydraulic system of a hydraulic excavator whole machine through a two-position four-way electromagnetic directional valve, and the two-position four-way electromagnetic directional valve is operated to control the expansion and contraction of a hydraulic cylinder, so that the accessories of the excavator can be replaced. However, since the excavator accessory changer is generally controlled by the operating handle, when the excavator performs construction work, the operator needs to perform construction work on the excavator by operating the operating handle, and therefore, the excavator accessory changer is easily controlled by mistakenly touching the operating handle, which may cause a safety accident.
