Described ultrasonic distance measuring module includes steel plate, ultrasonic sensor；The lower face of steel plate is the most right with the notch position of semicircle collecting tank；The number of ultrasonic sensor is multiple；Each ultrasonic sensor is both secured to the lower face of steel plate, and each ultrasonic sensor is by equidistant arrangement after forward direction；
Described Weighing module includes spring, bracing wire, stopping means, microswitch；The lower end of spring is connected with the lateral surface upper end of the first outer toroid by bracing wire；Stopping means is installed on the downside of the first outer toroid；Microswitch is fixed on stopping means；
Described processing module includes microprocessor, motor driver；The signal input part of microprocessor is connected with the signal output part of each ultrasonic sensor and the signal output part of microswitch respectively；The signal input part of motor driver is connected with the signal output part of microprocessor；The signal output part of motor driver is connected with the signal input part of motor.
During work, stopping means, microswitch, the lateral surface lower end of the second outer toroid are both placed on ground, and are hung up the upper end of spring, so that reserve gap between lateral surface lower end and the microswitch of the first outer toroid.Then, at one collecting box of each side placement of semicircle collecting tank, it is positioned at the collecting box on the left of semicircle collecting tank for collecting recyclable goods and materials, is positioned at the collecting box on the right side of semicircle collecting tank for collecting not Recyclable money.Then, being opened by each ultrasonic sensor, each ultrasonic sensor thus proceeds by range finding.Specific works process is as follows: when not having waste and old material to put in semicircle collecting tank, and the initial distance (this initial distance is i.e. equal to the distance between ultrasonic sensor and the medial surface lower end of semicircle collecting tank) recorded each is sent to microprocessor by each ultrasonic sensor in real time.Now, microswitch is off, and microprocessor reads the state of microswitch in real time.When there being waste and old material to put in semicircle collecting tank, it is positioned at the distance that the multiple ultrasonic sensors directly over waste and old material record all to change, the distance recorded each is sent to microprocessor by above-mentioned multiple ultrasonic sensor in real time, microprocessor thus calculates the difference between the distance after change and initial distance, and the diameter (this difference is i.e. equal to the diameter of waste and old material) of waste and old material is judged according to this difference, then the diameter of waste and old material is compared with setting value, judge thus according to comparative result whether the diameter of waste and old material transfinites.Meanwhile, microprocessor is according to the length (distance between ultrasonic sensor and position ultrasonic sensor the most rearward that in above-mentioned multiple ultrasonic sensors, position is the most forward is i.e. equal to the length of waste and old material) of the range estimation waste and old material between the most forward ultrasonic sensor and the position ultrasonic sensor the most rearward in position in above-mentioned multiple ultrasonic sensors, and the length of waste and old material is compared with setting value, judge thus according to comparative result whether the length of waste and old material transfinites.Now, under the weight effect of waste and old material, the front end of semicircle collecting tank moves down, and moves the first outer toroid by ring belt in first and move down, the first outer toroid and then drive spring stretch downward by bracing wire.If the lateral surface lower end of the first outer toroid does not touches microswitch, then microswitch is still within off-state, according to the state of microswitch, microprocessor judges that the weight of waste and old material does not transfinites.Otherwise, if the lateral surface lower end of the first outer toroid touches microswitch, then microswitch Guan Bi, according to the state of microswitch, microprocessor judges that the weight of waste and old material transfinites.When the diameter of waste and old material, length, weight all do not transfinite, microprocessor i.e. judges that waste and old material is as recyclable goods and materials.Now, microprocessor sends left rotaring signal to motor driver, motor driver controls motor according to left rotaring signal and turns left, motor passes sequentially through driving disk, annulus in first, inner screw, annulus drives semicircle collecting tank to overturn to the left in second, and waste and old material is thus poured into the collecting box being positioned on the left of semicircle collecting tank by semicircle collecting tank.When any one in the diameter of waste and old material, length, weight transfinites, microprocessor i.e. judges that waste and old material provides as not Recyclable.Now, microprocessor sends right turn signal to motor driver, motor driver controls motor according to right turn signal and turns right, motor passes sequentially through driving disk, annulus in first, inner screw, annulus drives semicircle collecting tank to overturn to the right in second, and waste and old material is thus poured into the collecting box being positioned on the right side of semicircle collecting tank by semicircle collecting tank.Based on said process, a kind of goods and materials identification device based on ultrasonic listening of the present invention is by using ultrasonic listening principle, it is achieved that be identified waste and old material.Compared with radio frequency identification technology, radio frequency+identification technology of weighing, a kind of goods and materials identification device based on ultrasonic listening of the present invention with bar code, can carry out the identification of waste and old material without waste and old material, and therefore its scope of application is the most limited.Compared with Material Identification technology, a kind of goods and materials identification device based on ultrasonic listening of the present invention realizes that cost is lower, technical difficulty is less, recognition efficiency is higher.
Present configuration rationally, design ingenious, efficiently solve that the existing waste and old material identification technology scope of application is limited, problem that to realize cost high, technical difficulty is big, recognition efficiency is low, it is adaptable to waste and old material reclaims.
