3, the utility model is arranged on strain gauge transducer in an elongated plates being provided with side disconnection finedraw, the tensile deformation of this plate is utilized to add the measuring distance of strain gauge transducer, improve the induction precision of strain gauge transducer, thus improve the detection accuracy rate of bin level detecting device.
Accompanying drawing explanation
Fig. 1 is the front view of this bin level strain sensing expansion detecting device.
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
By reference to the accompanying drawings detailed description of the invention of the present utility model is described.
As shown in Figure 1, Figure 2, this bin level strain sensing expansion detecting device has one and perpendicular puts plate 1, and this is perpendicular, and to put plate 1 be and the rectangular plate of hopper with material that the length of this rectangular plate should be 3 times of the strain gauge transducer length of use to 10 times.At perpendicular two ends up and down of putting plate 1, a connecting seat 2 is set respectively, the Connection Block 2 of accompanying drawing embodiment is rectangular plate type Connection Block, put plate 1 by welding be connected with perpendicular, the bottom surface of this Connection Block 2 coordinates with the outer side surface of hopper, by weld or bolt is fastened on the outer side surface of hopper.Perpendicular put the plate face of plate 1 and the bottom surface of Connection Block 2 is vertical surface.Be provided with horizontal side at perpendicular middle part of putting plate 1 and disconnect finedraw 3 and a strain gauge transducer 4.It is vertical with hopper outer side surface that side disconnects finedraw 3, can arrange parallel two or parallel and equal many of spacing, preferably arrange three.The width that every bar side disconnects finedraw 3 is 1mm-5mm, preferably 2 mm.Article three, side disconnects the opening of the finedraw in centre of finedraw 3 in perpendicular outer side edges of putting plate 1, and the opening of two other is at the perpendicular inner side edge putting plate 1.The length of side disconnection finedraw 3 should be perpendicular and puts 0.5 times of plate 1 width to 0.9 times.Strain gauge transducer 4 selects inserted strain sensor, and this sensor strides across side and disconnects finedraw 3, is fixedly mounted on a perpendicular side of putting plate 1 by the tie bolt 5 of portion placed on it and bottom respectively.Bar shaped clamping plate 6 and " clevis plate 7, this bar shaped clamping plate 6 and " clevis plate 7 is put plate 1 by binding bolt 8 and is connected with erecting, and forms and puts the three sides surrounded sliding groove structure in plate 1 edge to erecting are respectively arranged with at the perpendicular dual-side putting plate 1.As accompanying drawing embodiment, bolt 8 is applicable to being arranged on the side that side disconnects finedraw 3, can be arranged on top, also can be arranged on bottom.Bar shaped clamping plate 6 are with " length of clevis plate 7 should be doubly to 2.0 times of strain gauge transducer 4 length 1.5.By bar shaped clamping plate 6 with " effect of the sliding groove structure that clevis plate 7 form is that restriction is erected and put plate 1 and can only stretch along its length in testing process, does not offset to other directions.
The bin level that the utility model is specially adapted to tipper detects, and is also applicable to the material-level measure that other have identical function hopper or feed bin simultaneously.
