Electronic scale of loading machine

Abstract

The invention discloses an electronic scale of a loading machine. The electronic scale of the loading machine comprises (1) an oil pressure sensor installed at the position of a big arm oil inlet tube of the loading machine, (2) an angle sensor installed on a big arm, (3) a temperature sensor for measuring oil temperature, (4) a horizontal dip angle sensor for measuring a vehicle body and (5) a data processing and displaying module. A weighing region can be conveniently modified through an interface, and a problem that a weighing area and a weighing region are changeless due to the fact that a proximity switch is used is solved. An algorithm can determine to conduct data acquisition or not according to angle variation or not, and a problem that the big arm needs to pass through the weighing region at constant speed is solved. In addition, the dip angle sensor and the temperature sensor can timely monitor and modify the vehicle body and the oil temperature, and influences on weighing accuracy caused by uneven areas and oil temperature variation are removed. A large quantity of site using cases prove that the device is high in dynamic weighing accuracy, convenient to debug and capable of applying to complex working conditions and enables operation of a driver to be at will.

Description

technical field [0001] The invention relates to a weighing device, specifically a loader weighing device, in particular a loader weighing instrument with high precision and adaptable to complex working conditions, and can conveniently adjust the oversize of the weighing result On the small side. Background technique [0002] Loader electronic scale is a kind of loader weighing equipment, which is integrated with the mechanical control part of the loader and calculates the weight during the loading process of the loader. It monitors the predetermined weighing position through a proximity switch, and the hydraulic pressure Weighing is realized by converting to the weight of the load in the bucket. [0003] Composition: oil pressure sensor, used to collect pressure changes of the oil pressure system during loading; proximity switch, when the boom is lifted to the vicinity of the proximity switch, the system collects pressure data; instrument, processes and calculates the colle...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the loader electronic scales at home and abroad use the traditional proximity switch as the basis for data collection and weight calculation. The position of the proximity switch has been fixed when it is installed and the specific position of the boom cannot be judged, which has a high impact on the driver's operation. requirements, and when the loader’s work site has a large bump, the weighing result will have a large error. After a period of use, the weighing result has a large deviation and has to be re-adjusted, thereby reducing the use efficiency and affecting the use effect.
