Abstract
The utility model relates to an electronic scale, in particular to a vibration weight-drop scale, which is mainly used to weigh raw materials for preparing a sample of coal, ore and the like and belongs to the technical field of weighing. The weight-drop scale comprises a supporting frame, a hopper arranged on the supporting frame, frame upright posts arranged around the supporting frame and weighing sensors arranged on the supporting frame and the frame upright posts respectively, wherein the weighing sensors are connected with the hopper through pull rods; and a trough tray and a vibration feeding trough are arranged below the hopper. The sensors are arranged in the supporting frame, so the sensors are protected and interference from the outside with the sensors is reduced at the same time. Vibration-absorbing legs are arranged between the feeding trough and the trough tray, so influences of the vibrating feed trough on the sensors are reduced during operation. The vibrating feed trough adopts an instrument to control feed amount, so measurement accuracy is improved.
Description
Technical field
The utility model relates to a kind of electronic scales, is specifically related to a kind of vibration decrement scale, is mainly used in sample preparation batching weighings such as coal, ore, belongs to the weighing measurement technical field.
Background technology
At present, in the metering industry, sample preparation of known coal ore and batching mostly are a kind of method for making sample of extensive style, meticulous just method by hand.The weight of extensive sample preparation and batching can't be calculated accurately, supplies with and is difficult to reach accurate requirement.Some bucket scales in past adopt weighing part, hopper part and feed appliance are assembled into one, feed appliance is partly hung with hopper and is connected, and vibrations are big when feed like this, influence precision, also increased the instability of weighing simultaneously with hook, instrument control result displayed is also inaccurate.So far there is not good solution.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of vibration decrement scale is provided, it includes support frame, hopper is arranged on the support frame, there is upright of frame the both sides of support frame, be equipped with weighing sensor respectively on support frame and both sides upright of frame, weighing sensor is connected with hopper by pull bar, the vibrating feed groove is arranged below the hopper.Sensor is put into support frame; well protected sensor; also reduced simultaneously the interference of outer bound pair sensor; weighing sensor adopts that pull bar is direct-connected to be connected with hopper; with spheric washer hopper can be automatically reset, the damping leg is arranged between vibrating feed groove and the bucket body, when work, greatly reduce of the influence of vibrating feed groove sensor; the vibrating feed groove adopts instrument control feeding coal, has increased measuring accuracy.Instrument can more accurate control, gives a certain amount of material accurately at any time.This has just reached the degree of accuracy that improves sample preparation and feed, the purpose of sample preparation more accurately and batching.
The utility model is realized with following technical scheme: a kind of vibration decrement scale, it includes support frame, hopper is arranged on the support frame, it is characterized in that: upright of frame is arranged around the support frame, on support frame and upright of frame, be equipped with weighing sensor respectively, weighing sensor is connected with hopper by pull bar, hopper pallet and vibrating feed groove is arranged below the hopper.
Around the described support frame upright of frame is arranged, the lid of falling is arranged at the support frame top, is equipped with weighing sensor on support frame and upright of frame respectively, and weighing sensor is connected with hopper by pull bar, spheric washer is arranged below the pull bar.
Described weighing sensor is connected with hopper by pull bar, hopper pallet and vibrating feed groove is arranged below the hopper, between vibrating feed groove and the hopper pallet damping leg is arranged.
The utility model has the advantages that: this vibration decrement scale is simple in structure; sensor is put into support frame; well protected sensor; also reduced simultaneously the interference of outer bound pair sensor, weighing sensor adopts that pull bar is direct-connected to be connected with hopper, with spheric washer hopper can be automatically reset; the damping leg is arranged between vibrating feed groove and the bucket body; reduced the influence of vibrating feed groove to sensor when work, the vibrating feed groove adopts instrument control feeding coal, has increased measuring accuracy.Instrument can more accurate control, gives a certain amount of material accurately at any time.This has just reached the degree of accuracy that improves sample preparation and feed, the purpose of sample preparation more accurately and batching.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:

Embodiment
As shown in the figure: a kind of vibration decrement scale, it includes support frame 4, hopper 6 is arranged on the support frame, upright of frame 4-1 is arranged around the support frame, on support frame and upright of frame, be equipped with weighing sensor 2 respectively, weighing sensor is connected with hopper 6 by pull bar 3, hopper pallet 6-1 and vibrating feed groove 7 is arranged below the hopper.
Have upright of frame 4-1, support frame top to have to fall to cover 1, be equipped with weighing sensor 2 respectively on support frame and upright of frame around the described support frame, weighing sensor is connected with hopper 6 by pull bar 3, spheric washer 5 is arranged below the pull bar 3.
Described weighing sensor 2 is connected with hopper 6 by pull bar 3, hopper pallet 6-1 and vibrating feed groove 7 is arranged below the hopper, between vibrating feed groove and the hopper pallet 6-1 damping leg 7-1 is arranged.
The course of work: material is by apparatus for feeding (as the sieve that shakes, belt feeder etc.) material is sent into the hopper of weighing by setting value in batches carry out weighing, after material enters hopper, its gravimetric value is delivered to LOAD CELLS, sensor produces the electric signal input secondary instrument that is directly proportional with weight, shown numerical value carries out computing after instrument is handled, and weigh at every turn and calibration result compare, calculate its error and precision, when if in a single day apparatus system breaks down in the operation, host computer passes through after the fault analysis, promptly disposal route is proposed so that operating personnel in time handle with Chinese form, after weighing,, carry out the decrement batching by the data of prior setting by Vib. by the PLC output signal at every turn, feed is at regular time and quantity seen off institute by conveying equipment again to material.
