Abstract

The invention relates to the technical field of material loading and unloading, and discloses a material weighing method and device of an excavator, the excavator and a readable storage medium. The method comprises the steps that the torque of a movable arm oil cylinder, the mass torque of an excavating device and the distance from the material gravity center of a bucket to a movable arm shaft pin are obtained, and the excavating device comprises a movable arm, a bucket rod and the bucket; the difference value between the torque of the movable arm oil cylinder and the mass torque of the excavating device is calculated; and the weight of the bucket material is determined based on the ratio of the difference value to the distance from the gravity center of the bucket material to the movable arm shaft pin. According to the invention, automatic weighing of materials in the bucket is realized without intervention of human judgment, so that the excavation amount of the excavator can be effectively monitored, and the working time of the excavator can be reasonably distributed.

Description

technical field [0001] The invention relates to the technical field of material loading and unloading, in particular to an excavator material weighing method and device, an excavator and a readable storage medium. Background technique [0002] As a widely used excavation tool in the machinery industry, excavators often cooperate with trucks to complete the loading and unloading of ore, sand and other materials in practice. In order to improve the productivity of the excavator, a weighing system is usually configured on the excavator to accurately record the workload, reduce the weighing time, avoid overloading and overloading, and facilitate the reasonable arrangement of the working time of the excavator and prolong the service life of the excavator. At present, the weighing system configured on the excavator mainly relies on the dynamic inclination sensor to obtain pose and kinematic information for weighing calculation. For an excavator equipped with a digital oil cylinde...
