Abstract

The invention discloses a method for weighing and loading granular goods, in particular the method for weighing and loading coal. In the method, a device consisting of a surge bin, a quantitative bin, a quantitative bin hopper steelyard, a program controlled (PLC) electric automatic control system and a computer monitoring system is adopted. The granular goods are loaded by the method which comprises the following steps of: weighing the weight of goods in the quantitative bin by using the quantitative bin hopper steelyard; controlling hydraulic flat discharge gates of the surge bin and the quantitative bin; and closing a hydraulic flat discharge gate of a lower hopper of the surge bin after opening for 3 to 5 seconds when the quantity of the granular goods in the quantitative bin displayed on the quantitative bin hopper steelyard reaches vehicle loaded quantity. The method makes the loading quantity of a truck bed reach the standard of the vehicle loaded quantity, reduces punishment for contract breach and artificial supplement caused by the deficiency of loaded goods, and improves the accuracy of vehicle loaded goods quantity.

Description

technical field

[0001] The invention relates to a method for weighing and loading granular cargo, in particular to a method for weighing and loading coal. Background technique

[0002] At present, the weighing and loading devices for granular cargo, especially coal, mainly include buffer bins, quantitative bins, quantitative bin hopper scales, electrical automatic control systems with control modules PLC, and computer monitoring systems. Among them: the buffer bin is equipped with four lower hoppers, the lower hopper of each buffer bin is equipped with two hydraulic flat unloading gates, and the quantitative bin is equipped with two hydraulic flat unloading gates. The weight of the goods in the quantitative warehouse is weighed through the hopper scale of the quantitative warehouse, and the rapid weighing of the granular goods is realized by controlling the hydraulic flat unloading gates of the buffer warehouse and the quantitative warehouse, so as to complete the loading of...
