Embodiment Construction

[0031] The principle and preferred embodiments of the material metering control method and its material metering control device according to the present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not protect the present invention There are no restrictions on the scope.

[0032] In actual operation, the materials to be measured stored in the material bin are more than the demand for a single measurement. In the process of measuring, when the metering door of the material bin is opened, the materials will be continuously put into the weighing scale, and will be in the material bin and A continuous material curtain is formed between the weighing scales. The weight of the material accumulated in the weighing scale will be sensed by the load cell and restored to the weight of the material through the weighing control system, while the weight of the material cur...

Abstract

The invention relates to a material metering control method and a material metering control device. The material metering control method comprises the following steps: starting metering: starting a material bin metering door, guiding the material in a material bin to fall onto a metering scale and starting recording the metering time (t); confirming the time of closing the material bin metering door: according to a required target material weight (mB), utilizing a PLC (programmable logic controller) to calculate and confirm the time (tA) of closing the material bin metering door and the weight (mA) of the material in the scale at the moment by utilizing a linear or nonlinear regression method; and closing the material bin metering door: closing the material bin metering door when the metering time reaches the time tA or the weight of the material in the scale is equal to mA. According to the material metering control method and material metering control device provided by the invention, the mechanical structure of the metering scale is simplified and the metering precision and metering efficiency of a metering system are efficiently increased.

Description

technical field [0001] The invention relates to a material measurement control method and a material measurement control device in the construction machinery industry. Background technique [0002] In the construction machinery industry, the metering and mixing of materials (ie raw materials) are used in many places. Especially in cement concrete, asphalt concrete and other industries, it is necessary to accurately measure materials, and then achieve mixing to produce qualified finished materials. [0003] At present, from the analysis of the metering control devices used in the construction machinery industry, there are mainly two methods for material metering devices and their metering control methods: adding and subtracting methods. The main structural form of the additive weighing method is to set a weighing scale under the material bin. After the control system gives the material metering signal, the metering door of the material bin will automatically open and the mat...
