Two fulcrums 6 are by bearing 13, and journal stirrup 14 and cross-spring sheet constitute; Its mounting means has two kinds of pressure-bearing type and suspension types; Pressure-bearing type is installed as A group spring leaf 15 and is 0 °～45 with horizontal direction, and B group spring leaf 16 is 90 °～45 with level; Suspension type is installed as bearing 13 and hangs on the scale body, and on journal stirrup 14 fixed pedestals 8, two groups of bearings are 45 ° cross-spring sheet binding with one group with level.On the surface of rotating disk 2, stud with high-abrasive material, can change at any time.At charging aperture 1 place one group of carrying roller can be set as required, stressed evenly to guarantee rotating disk.The angle of discharging scraper 11 can be regulated as required.
Below be the utility model embodiment:
Before reinforced, adjust damper weight, make scale body both sides weight be in equilibrium state with respect to fulcrum, just begin blanking, material drops on the rotating disk 2 through charging aperture 1, rotating disk Rotate 180 °, to the discharging scraper position, scrape through scraper 11, half of rotating disk has material at this moment, second half does not have material, makes scale body out of trim, unbalance degree is directly proportional with weight of material on the rotating disk, be delivered on the LOAD CELLS 9 by the force transmission mechanism that is installed on the scale body, produce corresponding electric signal, the tachogenerator 12 that is installed in simultaneously on the dragging motor 4 detects the rotary speed signal, this binary signal imports simultaneously that computer controller is handled and computing, can measure material instantaneous delivery and integrated flow, carry out numeral demonstration or printing, reach the dynamic measurement purpose through rotating disk.
Two fulcrums 6 are a kind of novel cross-spring sheet mechanisms, and two kinds of pressure-bearing type and suspension types (Fig. 2,3) are arranged.
＜1〉pressure-bearing type (Fig. 2) has two groups of spring leafs of A, B, and A group spring leaf 15 and horizontal direction are 0 °～45 installs, and B group spring leaf 16 is 90 °～45 with horizontal direction to be installed, and can guarantee that two groups of spring leafs are orthogonal, stressed even.
＜2〉suspension type (Fig. 3) changes the bearing 13 of cross-spring sheet mechanism into pull-type bearing, hangs on the scale body, and journal stirrup 14 is fixed on the scale body, and the interior angle of two groups of spring leafs of A, B and horizontal direction is for being 45 °, and the scale body is in suspension status.
The advantage of the utility model garden dish weighing balance is as follows:
(1) charging aperture 1 and discharging scraper 11 are symmetrical in center of turntable and are arranged on rotating disk top two Side, the line at charging aperture and discharging scraper center is parallel with scale body two fulcrum lines and be in same In the vertical cross-section, this kind structure can significantly reduce the impulsive force that material produces in motion process To the impact of measuring accuracy, measuring accuracy can remain on ± and 0.5～1%.
(2) rotating disk is made by metal material, can carry 500 ℃ with interior high-temperature material.
(3) in the prior art, the supporting of square crossing type cross-spring sheet, two groups of spring leaf unbalance stress.The utility model design has pressure-bearing type and two kinds of support patterns of suspension type, has obviously improved the fulcrum bearing capacity, and its measures range is also corresponding to be widened, and measures range is 10kg/ hour～100 tons/hour.
