Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the examples.

[0029] The weighing method of excavator bucket material in the present embodiment, it comprises the following steps:

[0030] 1) First input L in the programmable logic controller (PLC) l , θ value and mg, L l is the distance from the pushing shaft to the top pulley, θ is the angle between the boom and the horizontal plane, mg is the self-weight of the bucket;

[0031] 2) The PLC reads the pulse number x of the lifting encoder, the pulse number y of the pushing encoder and the lifting motor torque T of the lifting inverter H and the pushing motor torque T of pushing the inverter C ;

[0032] 3) The PLC calculates the lifting stroke and pushing stroke according to the following formula and stores them in the memory,

[0033] S H = a 1024 * x

[0034] In the for...

Abstract

The invention relates to a method for weighting shovel material of an excavator, which belongs to a weighting method for weighting shovel material of a large-scale excavator. The invention mainly solves the technical difficulty that current excavators can not weight shovel material and count excavating yield. The technical proposal is that the weighting method of shovel material of a excavator comprises following steps, first, inputting L1, theta value and mg in a programmable logic controller (PLC), second, reading a pulse number x of a lifting encoder, a pulse number y of a driving encoder, a lifting motor torque TH of a lifting inverter and a driving motor torque TC of a pushing inverter through the PLC, third, calculating a lifting stroke and a pushing stroke, fourth, calculating an angle alpha and an angle gamma, fifth, calculating lifting power which is converted to an armored rope and pushing power which is converted to a pushing rod, sixth, calculating the weight of shovel and material, seventh, obtaining the weight of the material through reducing self-weight of the shovel from the weight of the shovel and the material.

Description

technical field [0001] The invention relates to a method for weighing materials in buckets of excavators, which belongs to a method for weighing materials in buckets of large mining excavators (WK-12-55, etc.). Background technique [0002] At present, large-scale mining excavators are mainly used in the excavation of soil, rock, ore, coal, etc. in large-scale open-pit mines, and load materials for mining vehicles. In order to count the excavation output, special personnel are required to record the number of loaded vehicles to estimate the excavation output, which will cause large errors and increase the input of personnel. Contents of the invention [0003] The purpose of the present invention is to solve the technical difficulties existing in the existing excavators that the bucket materials cannot be weighed and the excavation output cannot be counted, and to provide a weighing method for excavator bucket materials that can weigh the weight of excavator single bucket m...
