Abstract

The invention discloses an intelligent shoveling bus controlling system of a loader. According to the intelligent shoveling bus controlling system of the loader, a collecting bucket oil port, a movable arm lifting oil port, an overturning bucket oil port, a movable arm descending oil port and a floating oil port of an electric-hydraulic proportional pilot valve are connected with a collecting bucket oil port, a movable arm lifting oil port, an overturning bucket oil port, a movable arm descending oil port and a floating oil port of an electric-hydraulic proportional distribution valve respectively, a second oil inlet of the electric-hydraulic proportional pilot valve is connected with a large cavity of a movable arm oil cylinder, and an overturning bucket cylinder displacement sensor, a movable arm displacement sensor, a shoveling bucket horizontal displacement sensor, a main controller, a descending height setting button, a lifting height setting button, an electric control pilot handle and an engine controller are respectively connected with a bus. The intelligent shoveling bus controlling system of the loader is efficient, saves energy, is small in energy loss, improves the stability and comfort of work of the whole loader, is long in service life, is good in leveling function, avoids accidents, guarantees operation safety, improves operation efficiency, is favorable for upgrading and modification of products, and is used for controlling the shoveling process of the loader.

Description

technical field [0001] The invention relates to a control system for the shovel loading process of a loader. Background technique [0002] The current loader control system generally adopts hydraulic pilot control to reduce labor intensity and improve comfort. However, due to the uneven skill level of loader operators, in order to improve work efficiency, operators generally adopt extensive construction mode, and rarely consider By optimizing the operation method, the goal of high efficiency and energy saving is achieved. [0003] When carrying out shoveling operations, due to the great cutting resistance of the accumulated materials on the bucket, the operator needs to perform multiple step-by-step operations to complete the shoveling process. The operator controls the loader to cut into the material pile at a certain initial speed. As the amount of material accumulated in front of the bucket increases, the forward speed of the loader decreases sharply. At this time, the ...
