Abstract

The invention discloses an ingredient weighing metering device and method for a material self-loading mixer. The ingredient weighing metering device for the material self-loading mixer comprises an oil pressure sensor, a position measuring device and a calculation device; when in static weighing, the weight of an ingredient can be calculated by combination of the oil pressure of a large cavity and the oil pressure of a small cavity according the cross-sectional area of the large cavity and the cross-sectional area of the small cavity of a lifting oil cylinder; and / or when in dynamic weighing, the weight of an ingredient can be calculated by combination of the oil pressure of the large cavity and the oil pressure of the small cavity and the time for a lift arm to pass through a dynamic measurement position range according the cross-sectional area of the large cavity and the cross-sectional area of the small cavity of a lifting oil cylinder; the ingredient can be weighed by use of the ingredient weighing metering device and method for the material self-loading mixer.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to an ingredient weighing and measuring device for a self-feeding mixer and a method thereof. Background technique [0002] Self-loading mixers (such as Figure 11 (shown) is widely used in mines, tunnels, and small and medium-sized engineering construction. Its feeding mechanism can load various ingredients of concrete into the main mixer for concrete production. [0003] Concrete is made by mixing cement, sand, aggregate, additives, water and other ingredients. Strictly following the formula requirements and accurately controlling the addition of various ingredients is a necessary condition to ensure the quality of the produced concrete. The self-loading device of the concrete mixer is driven by a hydraulic cylinder, and the solid ingredients such as cement, sand, aggregate, additives, etc. are loaded into the mixing host by itself. Water and other liquid ingredients are ad...
