Problems solved by technology

The reality is that due to differences in loading site conditions, material properties, and operator fluctuations, there may be large differences in the shape of the material accumulation in the bucket and the center of gravity for each excavation
The use of parameter presets puts forward very high requirements on the accuracy of engineer data presets and operator operations; the use of sensors to correct the parameters of material shape and center of gravity position, be

Embodiment Construction

[0065] The implementation of the technical solution will be further described in detail below with reference to the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0066] Concept of the present invention: In this scheme, the bucket containing the material is regarded as a whole, and a center of gravity O is assumed for the whole in the space coordinates. G3 ; At a specific moment when the working device is stationary, use the known quantity and the collected quantity to simultaneously list the moment balance equation for two different points, and eliminate the assumed center of gravity O after the simultaneous combination G3 The effect on the solution for the weight G of the bucket loaded with material.

[0067] like Figures 1 to 3 As shown, an excavator weighing method is characterized in that, it includes the...

Abstract

The invention discloses an excavator weighing method, which comprises the following steps of: regarding a bucket filled with materials as a whole, and assuming a gravity center OG3 for the whole in a space coordinate; at a specific moment when a working device is static, moment balance equations are simultaneously listed for two different points by using the known quantity and the acquisition quantity, and the influence of hypothetical gravity center OG3 on solving of the weight G of a bucket filled with materials is eliminated after simultaneous listing. The total weight difference value of the materials and the bucket before and after the materials are unloaded is calculated, and the accumulative error influence of the residual materials in the bucket on the accumulative unloading amount is eliminated.

Description

technical field [0001] The invention discloses an excavator weighing method, which relates to the technical field of excavators. Background technique [0002] Excavators are widely used for unloading, loading and other tasks. In order to settle the construction volume and cost of the end user, the customer has a great demand for timely weighing and statistics of excavation and loading materials. However, due to the limitation of material properties, material quantity, site, equipment and other factors, it is not easy to achieve material weighing. [0003] In the existing intelligent weighing solutions for excavators, the center of gravity and the stacking shape of the material in the bucket are set in advance or approximated and brought into the balance equation for calculation. The reality is that due to differences in loading site conditions, material properties, and operator fluctuations, each excavation, the shape of the material accumulation in the bucket, and the cent...
