Abstract
The utility model discloses a belt weigher capable of automatic zero calibration. The belt weigher comprises a conveying belt, which has a first plane (1) for conveying materials and a second plane (2) without a load. Pressure transducers (3) are fixedly connected below the first plane (1) and the second plane (2) of the conveying belt. The utility model has the beneficial effects that the dead weight of the belt and the sum of the belt weight and the material weight can be respectively accumulated and calculated through the connection of the pressure transducers to the first plane and the second plane of the conveying belt, and the net weight of the materials can be obtained by deviation calculation, making the calculation precision higher, eliminating the need of manual zero calibration, saving the manpower cost and enhancing the efficiency.
Description
Technical field
The utility model relates to Belt Conveying dynamic measurement technology, relates in particular to the belt scale metering instrument.
Background technology
The belt conveyer scale display controller normally by a microprocessor synthetical collection pressure sensor signal and rate signal, then adopts the score accumulation method, the material of carrying on the continuous integration belt.The gravity that material forms at belt, through pressure transducer, produce differential pressure signal, through amplifying, then the processes such as AD conversion send the microcontroller collection, rate signal adopts pulse encoder mostly, be contained on the roller bearing, produce pulse signal for the microcontroller collection, pressure signal and rate signal integration accumulating operation are obtained semi-invariant.
At present, China belt conveyer scale producer way all is first after peeling heavy (value at zero point), add up computing, do like this definite value of worthwhile one-tenth of a zero point, do not consider when belt is not considered belt at convey materials when operation, because the humidity of material is different, with belt adhesion degree varies sample, even some material is attached on the belt.
The utility model content
Problem to be solved in the utility model is existing belt conveyer scale causes definite value of worthwhile one-tenth at zero point error in dipping when the accumulative total computing appearance, and a kind of belt conveyer scale that can automatically adjust the value at zero point is provided for this reason.
The technical solution of the utility model is a kind of belt conveyer scale of automatic zero adjustment, it comprises feed belt, described feed belt is divided into the first plane and not load-carrying second plane of transmitting material, and the first plane of described feed belt and below, the second plane are connected with respectively pressure transducer.
The beneficial effects of the utility model be by on the first plane of feed belt and the second plane respectively the Bonding pressure sensor come respectively cumulative calculation belt deadweight and belt and weight of material sum, calculate the net weight of material through difference, measuring accuracy is more accurate like this, and need not artificial school zero, save human cost, improved efficient.
Description of drawings
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the belt scale metering meter displaying device.
Embodiment
As shown in Figure 1, a kind of belt conveyer scale of automatic zero adjustment, it comprises feed belt, and described feed belt is divided into the first plane 1 and not load-carrying second plane 2 of transmitting material, and the first plane 1 of described feed belt and 2 belows, the second plane are connected with respectively pressure transducer 3.
The numerical value that pressure transducer metering under the first plane of above-mentioned feed belt obtains is G1, and the numerical value that the pressure transducer metering of the below, the second plane of feed belt obtains is G2, and so actual weight of material is G1-G2.
As shown in Figure 2, the pressure transducer of the first plane of described feed belt and below, the second plane is given respectively measuring instrument display device input weight signal, and the result of generation shows at display screen, and is easy to operate.
Claims (1)
1. the belt conveyer scale of an automatic zero adjustment, it comprises feed belt, described feed belt is divided into the first plane (1) and not load-carrying second plane (2) of transmitting material, it is characterized in that first plane (1) of described feed belt and the second plane (2) below are connected with respectively pressure transducer (3).
