Embodiment Construction
[0026] The specific implementation will be described below in conjunction with the accompanying drawings.
[0027]The loader automatic shovel loading system in this embodiment includes a loading system, a shovel loading action recording and playback system, and a control handle. The shovel loading action recording and playback system includes a controller connected to the loading system and a controller connected to the controller. The sensor is used to detect the rotation angle of the bucket and the lifting height of the boom, and the control handle is connected with the controller. The charging system includes hydraulic pump, bucket cylinder, boom lift cylinder, bucket solenoid valve group and boom lift solenoid valve group; the hydraulic pump is connected to the bucket cylinder through the bucket solenoid valve group, and the hydraulic pump is connected to the bucket cylinder through the boom lifting electromagnetic The valve group is connected to the boom lifting cylinder;...

The invention relates to the automatic shovel loading of loaders, in order to solve the problems existing in the recording and playback of shovel loading actions in the automatic shovel loading process of existing loaders; an automatic shovel loading system for loaders is provided, which includes a shovel loading action recording and playback system , when the shoveling action is recorded, the bucket retracting range is divided into several angle intervals with equal angles. When the shoveling action is recorded, each time the bucket passes through an angle interval, the bucket retracting current, the boom lifting current and the angle interval are recorded once. The time used is used as a set of shoveling action data and stored until the end of the bucket; when the shoveling action is played back, the controller outputs the bucket closing current and the boom lifting current according to the angle range of the bucket and the corresponding shoveling action data group, and completes Automatic shovel loading. The invention can reduce the impact caused by the movement of the bucket, lower the technical threshold of shoveling and recording, and is beneficial to improve the efficiency of shoveling and reduce the operating intensity of the driver. .
Description
technical field [0001] The invention relates to a loader, more specifically, to an automatic shovel loading system and a control method for the loader. Background technique [0002] With the development of loader technology and intelligent technology, loader products have become more and more intelligent. For example, some loaders need to have automatic shovel loading function. Automatic shovel loading means that after the loader bucket is inserted into the material pile, the control system of the loader outputs the bucket closing current and the boom lifting current according to the loading control parameters, so that the loading system performs a coordinated bucket closing action and boom lifting action, thereby completing the step of loading materials into the hopper. Therefore, the loading control parameters are indispensable data for automatic shovel loading by the loader. [0003] There are mainly two ways to set the charging control parameters of the existing loader...
