Technical background
Belt conveyer scale is the weighing metrology devices that is widely used in the industrial processes, because its work under bad environment, disturbing factor is many, and therefore, the accuracy of the weight metering of existing belt conveyer scale and stability are all bad.
Chinese patent ZL00230148.2 discloses a kind of " eliminating sideslip power, tilting force belt conveyer scale scale frame ", and this device comprises sensor holder (machine) frame, four pressure (dynamometry) sensor, scale frame; Sensor is arranged on the mounting, and the scale frame is arranged on the sensor; Comprise two channel-section steels on the scale frame, be welded to each other between two channel-section steels that four sensors are supported on the two ends of scale frame two channel-section steels respectively, sensor is perpendicular to scale frame plane; The roller rack of feed belt is arranged on the scale frame; Also dispose the buting iron of 4 rectangular cylindricalitys on the sensor frame, their two sides parallel with the traffic direction of driving belt; Two medial surfaces of each rectangular cylinder touch mutually with the pivot arm that is lifted on scale frame below respectively.
This patented technology adopts the buting iron of 4 rectangular cylindricalitys to be scale frame location, with eliminate the driving belt scale in operational process because the lateral deviation power that belt deviation causes and because the tilting force that the inclination angle of belt causes, therefore have following defective: 1, the pivot arm owing to scale frame below touches mutually with the buting iron of rectangular cylindricality, can not realize that the scale frame suspends entirely, very easily cause the power on the scale frame directly to be delivered on sensor holder (machine) frame, influence the accuracy of belt conveyer scale weight metering by the buting iron of rectangular cylindricality; 2, the buting iron of rectangular cylindricality touches mutually with pivot arm, use a period of time after because the distortion of scale frame, the buting iron of rectangular cylindricality very easily with the pivot arm dieback, it is unstable to cause belt conveyer scale to use, and influence the serviceable life of belt conveyer scale, so must regularly debug pivot arm.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of high precision full suspension type belt conveyer scale is provided, and it can further improve the precision and the stability of weight metering, and long service life, need not regularly debug.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: it comprises sensor mounting, four pressure transducers, scale frame; Sensor is fixedly installed on the mounting, and the scale frame is by four sensor support, and sensor is perpendicular to scale frame plane; The roller rack of feed belt is arranged on the scale frame; Be respectively equipped with round depression spare between each sensor and the scale frame, circle depression spare is enclosed within on the sensor support bar of sensor, fixedlys connected with the scale frame in the top of circle depression spare.
With respect to prior art, the utility model has been realized the full suspension of scale frame, and promptly the scale frame is installed on the pressure transducer with suspending fully, therefore, has further improved the precision of the weight metering of belt conveyer scale; In addition, scale frame of the present utility model is positioned on the sensor by four round depression spares, makes the scale frame be in the full suspended state of non-displacement, can not cause the dieback phenomenon, therefore, belt conveyer scale need not regularly be debugged, and also can use for a long time, good stability, long service life is applicable to the belt feeder at any inclination angle.
