Description
Technical Field
The utility model relates to a device for measuring material weight in feed bin belongs to and measures technical field.
Background
Material testing is an important component of process control systems for many manufacturing and manufacturing enterprises, including steel plants. At present, the weight of material generally detects by the weighing sensor who sets up in the feed bin bottom in the feed bin, nevertheless to some feed bins that receive the vibration source influence (be equipped with vibrating feeder's feed bin like the discharge gate, vibrating feeder operation can form a disturbance to the feed bin and support), weighing sensor's measured value can appear great undulant, can not reflect the weight of material in the storehouse like this, this kind of measurement error can lead to the fact harmful effects to process control system, great detection error leads to the feed bin flash, thereby still can influence going on smoothly of production. Therefore, it is necessary to design a device for measuring the weight of the materials in the bin, which is not affected by the vibration source.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a non-contact material weight measuring device to the drawback of prior art to eliminate the influence of vibration source to the measured value, improve the measurement accuracy of material weight.
The problem of the utility model is solved with following technical scheme:
the utility model provides a non-contact material weight measuring device, includes laser range finder, distancer support and PLC, the laser range finder is located the top of feed bin and is connected with the lateral wall of feed bin through the distancer support, and the laser range finder's laser range sensor is relative rather than the feed bin material of below, and the signal output part of laser range finder is connected with PLC's signal input part.
Above-mentioned non-contact material weight measuring device, the distancer support includes support and telescopic link, the support is fixed on the lateral wall of feed bin, the telescopic link is located the top and the level of feed bin and places, and the one end of telescopic link is passed through vertical pivot and is connected with the support rotation, and laser range finder installs on the telescopic link.
According to the non-contact material weight measuring device, the telescopic rod comprises a shaft sleeve, a cross rod, a sleeve and a locking bolt, the shaft sleeve is slidably sleeved on the vertical rotating shaft on the support, one end of the cross rod is fixedly connected with the shaft sleeve, the other end of the cross rod is inserted into the sleeve, and the locking bolt is screwed into a threaded hole in the sleeve and abuts against the cross rod.
