Description
Technical Field
The utility model relates to a bulk material weighing device, especially a two bearing roller of belt weigher intelligent platform that suspends entirely.
Background
A belt scale refers to an automatic weighing apparatus that continuously weighs bulk materials on a conveyor belt without subdividing the mass or interrupting the movement of the conveyor belt.
At present, the existing belt weighers are designed and manufactured based on adaptive dynamic conditions and principles, applied field weight detection modes comprise a multi-carrier roller lever type, a multi-carrier roller hanging and pull rod positioning type, a single-carrier roller direct-pressing type and a variety thereof, and the like, and in practical application, the modes have some defects:
one, form defects of multi-idler class:
1. because the force measuring structure is rigidly connected with the outside, more or less interference, errors and even larger errors are inevitably brought, and errors are also generated when materials are in unbalance loading.
2. Because the operating environment of the belt scale is that the belt and the carrier roller operate ceaselessly for a long time, the rigid connection of the multi-carrier roller force measurement structure and the outside can generate mechanical deformation to influence the measurement precision due to the vibration generated by long-term operation, and the time and the intensity of the deformation are irregular and cannot be predicted, so that an uncontrollable measurement error can be generated.
3. Due to the complex structure, the maintenance amount is large and the number of fault points is large.
Secondly, the single-support roller direct-pressing type and the variety thereof solve the defect of rigid connection with the outside, and the defects are as follows:
1. because only one carrier roller is provided, the metering stress is a line, and the fluctuation resistance capability is poor, and the material fluctuation and unbalance loading time error are large in the dynamic environment of belt conveying.
2. Because only one carrier roller is provided, the metering stress is a line, the range of the material detection is narrow and less, and the metering precision is poor.
3. The anti-fluctuation, anti-vibration and anti-interference capabilities are poor, and large errors are generated when materials fluctuate and a belt or a conveyor vibrates and deviates.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a two bearing roller of belt weigher intelligence platform that suspends entirely.
The purpose of the utility model is realized through the following ways: the utility model provides a two bearing roller full-suspension intelligent platform of belt weigher, this platform is installed on belt conveyor main longitudinal beam of belt weigher through supporting the channel-section steel is horizontal, support channel-section steel both ends install a pressure sensor respectively, the last bearing roller support of installing of pressure sensor, parallel mount has two measurement bearing rollers between two bearing roller supports.
As a further optimization of the scheme, two fixing modes of the supporting channel steel and the main longitudinal beams of the belt conveyor are provided, wherein one mode is that two ends of the supporting channel steel are directly welded and fixed on the inner sides of the main longitudinal beams of the two belt conveyors; the other type is that angle steel is respectively welded at two ends of the supporting channel steel and is fastened on the left and right 2 screw hole plates through bolts, and the 2 screw hole plates are welded at the symmetrical positions of the main longitudinal beam of the belt conveyor.
As a further optimization of the scheme, the metering carrier roller is movably arranged on the carrier roller bracket through an adjusting bolt.
The utility model relates to a two bearing roller of belt weigher intelligence platform that suspends entirely, compared with prior art, have following advantage:
1. the device is not rigidly connected with the outside, so that the interference and the error caused by the connection are completely solved, and the influence of the vibration generated by the long-term operation of the device on the metering is minimized.
2.
