Embodiment Construction

[0025] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] An embodiment of the present invention provides an excavator, figure 2 is a schematic diagram of the geometric structure of an excavator according to an embodiment of the present invention, such as figure 2 As shown, the angle between the stick 12 and the horizontal plane is α2, the angle between the boom 13 and the horizontal plane is α1, and the angle between the stick 12 and the boom 13 is α3. It can be seen from the figure The relationship between the three included angles is: α1+α2+α3=180°, so if any two angles of the above three angles are obtained, the remaining angle can be obtained according to the above relationship. When the lengths of the boom 13 and the arm 12 are fixed,...

Abstract

The invention provides a flat-pushing control method and device of an excavator and the excavator. The flat-pushing control method of the excavator comprises: controlling a bucket rod cylinder to push a bucket to operate according to control instructions of operators; acquiring gesture changing of a bucket rod in real time; and performing feedback control on oil-inlet amount of a movable arm cylinder according to the gesture changing of the bucket rod so as to enable a bucket to be at the preset height. In flat-pushing operation, the operators of the excavator give out cylinder extending orders to the bucket rod cylinder by controlling an operation device of the bucket rod and perform feedback control on the movable arm cylinder according to the bucket rod gesture measured in real time, so that the inclined angle formed by a movable arm and the horizontal plane and the inclined angle formed by the movable arm and the bucket rod change in matching mode, changing of the movable arm is used for coordinating changing of the bucket rod, the height of the bucket is ensured to be stable when flat-pushing of the bucket is ensured, accordingly fatigue degree of the operators is reduced, and partial excavating work can be finished automatically.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a method and control device for horizontally pushing an excavator, and the excavator. Background technique [0002] Excavators, especially face shovels, require constant push operations. When the excavator completes the leveling operation, it is necessary to keep the height of the bucket stable. [0003] figure 1 It is a schematic diagram of the operation executive mechanism of the excavator in the prior art, such as figure 1 As shown, the operation executive mechanism of the excavator includes a bucket 11, a stick 12, a boom 13, a boom cylinder 14, and a stick cylinder 15. As can be seen in the figure, the height of the bucket 11 is determined by the bucket 12 and the The posture of the boom 13 is determined. And the posture of bucket rod 12 and boom 13 is jointly determined by the expansion and contraction of boom cylinder 14 and boom cylinder 15. When the excavator is...
