Problems solved by technology

[0004] Although the above-mentioned volume measurement method can basically meet the small-dose admixture measurement problem in mortar mixing, there is still a certain distance between the measurement accuracy of the above-mentioned method and the required accuracy.
First of all, due to different temperatures, the same dose of admixture will have different volumes due to thermal expansion and contraction, which will cause temperature errors
In addition, because the measurement is generally in the on-site working environment, the measurement container is often in a state of vibration, and it is difficult for the observer to observe accurately, which will cause observation errors

Embodiment Construction

[0017] Please refer to FIG. 1 , which shows a schematic structural view of an admixture metering device for mixing construction mortar provided by the first embodiment of the present invention.

[0018] As shown in the figure, the metering container 1 of the admixture metering device is suspended on the frame 12 through the suspension rod installed with the load cell 2, and the bottom of the metering container 1 is provided with an admixture outlet 5, and the admixture outlet 5 The setting position can make the admixture loaded into the metering container 1 flow out from the outlet. The admixture outlet 5 is equipped with a control outlet opening or closing valve (not shown), so that the outlet can be in an open or closed state as required. The load cell 2 can weigh the weight of the metering container 1 and the additive therein, and the user can obtain the accurate weight of the additive by subtracting the weight of the metering container 1 from the value. In addition, in th...

Abstract

The invention discloses an admixture measuring device used for mixing construction mortar, a weighting sensor support and hanging support or hanging; the admixture is opened at the bottom of the measuring vessel. Optimizedly, the bottom of the measuring vessel is also opened with admixture entrance. Optimizedly, the admixture entrance is arranged with a pipeline of transferring pump, the admixture adsorbs the measuring vessel along the pipeline in the admixture agent by a transmission pump. Optimizedly, the transmission pump adopts speed change motor driving. The device discloses in the invention arranges a weighing device on the measuring vessel, to achieve the measuring volume by the test vessel, which can prevent temperature error, and won't produce the watch error caused of shaking.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a metering device for an admixture for mixing construction mortar. Background technique [0002] Mortar is mixed during construction. All kinds of mortars include several components, and there are certain proportioning relationships between these components, which must be followed during the mixing process, otherwise the mixed mortar will not meet the construction requirements. Especially in the process of building high-speed railways or highways, it is necessary to mix a special asphalt cement mortar, and the ratio between the various components is more stringent, especially in this kind of mortar except for the main components. In addition, a small dose of liquid admixture is also added. Since the amount of these admixtures added is small, a slight measurement error will cause a large change in the properties of the mortar. Therefore, more accurate measurement o...
