Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 5, an integrated sensor for garbage classification comprises a plurality of cross beams 1, a first elastic body 2 and a second elastic body 3, wherein the first elastic body 2 is connected with the left end of each cross beam 1, the second elastic body 3 is connected with the right end of each cross beam 1, a plurality of deformation holes 4 are formed in the first elastic body 2 and the second elastic body 3, and strain gauges 5 are arranged in the deformation holes 4. In order to place the garbage can, a rectangular plate is usually placed on the upper ends of the beam 1 and the two elastic bodies, the garbage can is placed on the rectangular plate, when garbage is placed in the garbage can, the deformation holes 4 in the first elastic body 2 and the second elastic body 3 are deformed due to the increased weight, so that the wheatstone bridge formed by the strain gauges 5 is unbalanced and converted into differential voltage, and finally the differential voltage is converted into the weight value of the output garbage. And the integral type sensor that is formed by a plurality of crossbeams 1, first elastomer 2 and second elastomer 3, its whole span is big, small, highly hangs down to it is very convenient to install, is favorable to the installation environment of garbage bin this type and makes things convenient for the garbage bin loading and unloading.

In this embodiment, the plurality of cross beams 1 are parallel to each other, and the first elastic body 2 and the second elastic body 3 are perpendicular to the cross beams 1, respectively. Stability and fastness of span have been guaranteed through above-mentioned setting to can stabilize and install the garbage bin that is used for waste classification in its upper end.

In this embodiment, the first elastic body 2 and the second elastic body 3 are both in the shape of a strip. The design of bar form guarantees that its measuring span is bigger, and the scope is wider to can install in comparatively narrow and small space, not restricted by the installation environment.

In this embodiment, leveling devices 4 are disposed in the first elastic body 2 and the second elastic body 3. The leveling device 4 can level the whole sensor and keep the sensor in a horizontal state, thereby ensuring the accuracy of measurement.

In this embodiment, leveling device 6 from last to including lock nut 7, last pressure head 8, steel ball 9 and lower pressure head 10 down in proper order, lock nut 7 and last pressure head 8 all with
