[0023] The detection box 1 can be made of insulating materials such as polyethylene. The detection box 1 is provided with two handles 6 at the rear side, and two connecting arms 7 are respectively arranged at the upper part of the left and right sides of the detection box 1. The connecting arms 7 are provided with connecting holes extending through the front and rear sides. The two connecting arms 7 are used in cooperation with the subsequent turnover clamping mechanism, so that the turnover clamping mechanism can clamp and turn over the detection box 1 for discharging. The detection box 1 is provided with an alarm and a detection coil. The detection box 1 is provided with a detection end alarm contact group 8 and a detection end coil contact group 9 at the front side. The two poles of the alarm are connected to the two detection end alarm contacts of the detection end alarm contact group 8 through wires. The detection end coil contact group 9 includes two detection end coil contacts which are extended from the two ends of the detection coil.

[0024] In this embodiment, the detection box 1 is provided with two detection coils which are respectively arranged inside the left and right sides of the detection box 1. The two detection coils are respectively an A-phase detection coil and a B-phase detection coil. Correspondingly, the detection box 1 is provided with two independent detection end coil contact groups 9 at the front side, and the two detection end coil contact groups 9 correspond to the two detection coils respectively. The detection box 1 is provided with two alarms which are respectively an acoustic alarm 13 and a light alarm 14. Correspondingly, the detection box 1 is provided with two independent detection end alarm contact groups 8 at the front side, and the two detection end alarm contact groups 8 correspond to the two alarms respectively.

[0025] Correspondingly, the detection box 1 is provided with two independent detection end alarm contact groups 8 at the front side, and the two detection end alarm contact groups 8 correspond to the two alarms respectively.

[0026] The detection box 1 is provided with two independent detection end alarm contact groups 8 at the front side, and the two detection end alarm contact groups 8 correspond to the two alarms respectively.

[0027] Figure 4The control circuit diagram of the control circuit board, wherein L1 is a coil, C1, C2, C3, C4, C5 are capacitors, Q1, Q2, Q3 are triodes, R1, R2, R3, R4 are resistors, and S1 is a start-stop switch. The two alarm contacts of the mobile alarm contact group 11 corresponding to the sound alarm 13 are connected to the p1 and p2 ports in the control circuit respectively; the two alarm contacts of the mobile alarm contact group 11 corresponding to the light alarm 14 are connected to the p3 and p4 ports in the control circuit respectively. The control circuit is powered by a power module, S1 is a switch, and the opening or closing of the switch S1 is realized through the start button 15 and the stop button 16 on the front side of the mobile box 10, so as to turn on or turn off the control circuit. The A-phase detection coil and the B-phase detection coil are connected in series together with L1, C2, C3, and Q1 to form a high-frequency oscillation circuit, and Q2 and Q3 form a detection circuit. When there is no metal foreign matter within the detection distance of the A-phase detection coil and the B-phase detection coil, Q2 is turned on, Q3 is turned off, p1, p2, p3, and p4 are not turned on, and the sound alarm 13 and the light alarm 14 do not work. However, when metal appears within the detection range of the A-phase detection coil and the B-phase detection coil, eddy current will be generated in the metal, which will affect the oscillation circuit and cause the oscillation circuit to gradually stop oscillating. At this time, Q2 is turned off, Q3 is turned on, p1, p2, and p3, p4 are turned on, and the sound alarm 13 and the light alarm 14 are triggered to produce sound alarm and light alarm. The sound alarm 13 can be selected as an FMQ-2715 buzzer, the light alarm 14 can be selected as an LTE-5061 warning light, and the gain regulator is used to change the gain of the oscillator.

[0028] In use, the detection device is moved to the working site by holding the handrails 18, and the detection box 1 is pushed forward by holding the two handles 6 until it contacts the moving box 10, so that the two groups of detection end alarm contact groups 8 on the front side of the detection box 1 respectively contact the two groups of moving end alarm contact groups 11 on the rear side of the moving box 10, and the two groups of detection end coil contact groups 9 on the front side of the detection box 1 respectively contact the two groups of moving end coil contact groups 12 on the rear side of the moving box 10. At this time, the start button 15 is pressed, the control circuit is powered on, the blade material to be detected is placed in the detection box 1, and the A-phase detection coil and the B-phase detection coil of the control circuit start to detect the material in the detection box 1. When the material contains metal, the turbulence signal generated by the metal will affect the oscillation circuit in the control circuit, and the balance of the oscillation circuit will be destroyed. At this time, the sound alarm 13 emits a sound alarm to prompt the presence of metal, and the light alarm 14 emits a red light to prompt the presence of metal. The operator can stop the detection by the stop button 16, check the material, and find the metal foreign matter. Then the control circuit is started again to check whether the metal foreign matter is completely removed. If the detection device does not emit a sound alarm signal and a light alarm signal after starting, it means that the material does not contain metal foreign matter, and the operator can perform the next operation on the material according to the process requirements. The power module uses rechargeable lithium batteries, which can supply power to the control circuit board of the device at any time. When the power is insufficient, the power module can be charged through the power plug 17 on the moving vehicle body.

[0029] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the present application.
