Abstract

The invention relates to the technical field of mechanical equipment, and particularly to an adjustable electronic belt conveyor scale object detecting hanging weight calibrating device. The device comprises a base, a mounting trough, a pressure sensor, an electronic belt scale body, a mounting board, a chamber, a chute, a top board, a connecting block, an electric push rod, a hanging weight, a groove, an electromagnet, an infrared opposed switch and a controller. The hanging weight is mounted on the top board when not in use. Furthermore the top board is in the chamber. Therefore the electronic belt scale is not affected by the top board in an operation process, and convenient conveying is realized. Furthermore when the electronic belt scale needs calibration, the electric push rod can move the top board to surface of the mounting board, thereby making the hanging weight be arranged above the electronic belt scale. Simultaneously the electromagnet is powered off, and the hanging weight is arranged on the surface of the electronic belt scale. Through the pressure sensor, dynamic verification and calibration of the electronic belt scale are realized.

Description

technical field

[0001] The invention relates to the technical field of mechanical equipment, in particular to an adjustable hanging code verification device for physical verification of electronic belt scales. Background technique

[0002] Electronic belt scales have been widely used in process measurement and assessment of industrial bulk materials such as electric power, steel, mines, and docks. The existing electronic belt scale must carry out zero point detection and range calibration to the belt scale before working. The current calibration method generally adopts physical calibration and simulated calibration. The physical calibration method is more accurate, but it consumes manpower, material resources, and high cost. It is not suitable for frequent calibration, and many sites do not have the conditions for implementation. The simulated weight is generally the method of chain code verification and hanging code verification. The chain code verification equipment is la...
