Abstract

The invention provides a loader-digger bucket posture adjusting method and device and a loader-digger. The adjusting method comprises the steps of obtaining the preset relative position between a piston and a cylinder block of a bucket oil cylinder when the loader-digger bucket is in a preset attitude; and in the loader-digger bucket posture adjusting process, controlling the bucket oil cylinder to contract back or extend out until the actual relative position between the piston and the cylinder block of the bucket oil cylinder is coincident with the preset relative position. By means of the adjusting method, loader-digger bucket posture accurate adjustment can be realized, errors are effectively reduced, and the operation efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of backhoe loaders, in particular to a method and device for adjusting the attitude of a backhoe loader bucket and the backhoe loader. Background technique [0002] After the bucket of the backhoe loader is unloaded, it is necessary to retract the bucket first, and then lower the boom, and the bucket needs to be retracted to a certain position, so that after the boom is lowered, the bucket and the working surface are at a specific position, which is Prepare for the next bucket operation. [0003] The current step of adjusting the attitude of the bucket is usually achieved by the operator based on experience and visual inspection, which has poor accuracy and great randomness, making it difficult to accurately adjust the bucket to a preset position. Contents of the invention [0004] In view of this, the purpose of the present application is to provide a method and device for adjusting the attitud...
