Abstract

The invention discloses a device and a method for detecting material level of a silo in a concrete mixing plant. The device comprises a knocking device and a sound wave detection device arranged outside the silo. The knocking device is used for knocking the outer wall of the silo to generate sound waves, and the sound wave detection device is used for detecting the sound waves to determine the level of material in the silo. According to the device and the method for detecting material level of the silo in the concrete mixing plant, the heights of material levels of the silo can be continuously measured simply and conveniently, the problem of continuously measuring the heights of material levels of the silo in the concrete mixing plant or other working conditions is overcome, the detection result is accurate and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a device and method for detecting material level in a silo of a concrete mixing station. Background technique [0002] The silo is a tank used to store cement and other powder materials on the concrete mixing plant. There are usually four silos in the concrete mixing plant, which store powder materials such as cement and admixtures (both are raw materials for the production of concrete). When the production volume of the mixing station is relatively large, the consumption of powder is very large. Sometimes when the low material level of the silo is alarmed before filling the material, it is likely to delay production and cause great losses to the enterprise. Therefore, it is very necessary for the production of enterprises to know exactly the height of materials through some method. [0003] At present, the method of judging the material level of the silo is to in...
