Problems solved by technology

[0002] Existing products usually use electromagnetic sensors to collect the relative angle between the loading arm and the car body, and combine the cylinder pressure for weighing calculations. Because the horizontal inclination angle of the bushing during the loader’s operation is not collected, it cannot be ruled out that the actual working process of the loader is due to The influence of the slope of the bottom surface of the workplace and the bumps of the vehicle body

Abstract

The invention discloses a loader and a high-precision weighing method of the loader, and belongs to the technical field of electronic scales of loaders. A displacement detection sensor used for detecting the extension length of a piston rod of a lifting oil cylinder and a vehicle body posture sensor used for detecting the inclination angle of a vehicle body relative to the horizontal bottom surface are installed on the lifting oil cylinder; primary weighing calculation is carried out through the extension length of the piston rod of the oil cylinder, the relative angle of the vehicle body andthe pressure of the oil cylinder, then the primary weighing structure is corrected in combination with the current vehicle body inclination angle posture, the influence of the vehicle body inclinationangle on weighing is eliminated, and the weighing error is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of loader electronic scales, and in particular relates to a loader and a high-precision weighing method for the loader. Background technique [0002] Existing products usually use electromagnetic sensors to collect the relative angle between the loading arm and the car body, and combine the cylinder pressure for weighing calculations. Because the horizontal inclination angle of the bushing during the loader’s operation is not collected, it cannot be ruled out that the actual working process of the loader is due to The influence of the slope of the bottom surface of the workplace and the bumps of the car body. Contents of the invention [0003] The object of the present invention is to provide a loader and a high-precision weighing method for the loader. By installing a displacement detection sensor on the lift cylinder for detecting the elongation of the piston rod of the lift cylinder, a displacement dete...
