All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, a metal detector for automatically recycling small parts includes a transmission belt 1, a coil panel 4 and a sorter 10, wherein a transmission wheel 2 is movably sleeved on an inner ring of the transmission belt 1, a part 3 is placed on an upper surface of the transmission belt 1, a magnetic field coil 5 is fixedly connected inside the coil panel 4, a detection panel 6 is fixedly connected outside the coil panel 4, a pointer 7 is rotatably connected inside the detection panel 6, an arc groove 8 is formed inside the detection panel 6, a contact 9 is movably clamped inside the arc groove 8, a nozzle 11 is fixedly connected on an outer ring of the sorter 10, a conduction pipe 12 is fixedly connected on the outer ring of the sorter 10, a diversion port 13 is formed on the outer ring of the sorter 10, a rotary valve 14 is rotatably connected inside the rotary valve 14, a T-shaped channel 15 is formed inside the rotary valve 14, and a reset spring 16 is fixedly connected on a side end of the rotary valve, an electromagnet 17 is fixedly connected to the side end of the return spring 16.

Wherein: the spacing between the parts 3 is no less than twice the diameter of the nozzle 11. The proper spacing of the parts 3 can ensure that the nozzle 11 can only affect a single part 3, reduce the probability of false touch, and simultaneously avoid the problem of reduced sorting efficiency caused by overlarge spacing.

Wherein: the magnetic field coil 5 is supplied with an intermittent current. The intermittent current can generate an induction magnetic field with a changing magnitude, and a self-induction current and a self-induction magnetic field which change synchronously are generated in the part 3.

Wherein: the pointer 7 is embodied as a position-sensitive magnetic field sensor which is electrically connected to the magnetic field coil 5 fixedly connected to the interior of the coil disk 4. The sensitive magnetic field inductor is connected to the magnetic field coil 5, and is used for detecting the influence of a self-induction magnetic field generated by the part 3 on the magnetic field of the magnetic field coil 5 while synchronizing the constantly changing magnetic field in the magnetic field coil 5, so as to judge the content of the magnetic metal in the part 3, and the content is shown by the rotating angle of the pointer 7 on the detection disc 6.

Wherein: the pointer 7 and the contact 9 are electrically connected with the electromagnet 17. When the hands 7 are rotated so that the contacts 9 touch each other, the electromagnet 17 starts to operate.

Wherein: the coil disk 4 is fixedly arranged directly above the conveyor belt 1, the sorter 10 is in the same horizontal position as the component 3, and furthermore, the coil disk 4 and the sorter 10 are in the same vertical cross-sectional position.

Wherein: when the return spring 16 is in the potential-free state, two of the ports of the T-shaped passage 15 are aligned with the diversion port 13 and the conduction tube 12, respectively, and the third port is not aligned with the nozzle 11. When the electromagnet 17 does not work, the conduction pipe 12 is butted with the shunt port 13.

Wherein: the conduction pipe 12 conducts high-pressure gas from the external equipment to the inside

The working principle is as follows: the drive wheel 2 is driven by an external motor to rotate, so that the drive belt 1 drives the part 3 placed at the upper end to move horizontally, when the part 3 moves to the positions of the coil panel 4 and the detection panel 6, which are the same as the vertical section, the continuous intermittent current conducted in the magnetic field coil 5 can generate an induction magnetic field with continuously changed size, and the self-induction current and the self-induction magnetic field are synchronously changed in the part 3. The self-induction current and the self-induction magnetic field generated in the part 3 can adversely affect the magnetic field of the magnetic field coil 5, the detection disc 6 can detect the variation of the magnetic field in the magnetic field coil 5 and show the variation through the rotation angle of the pointer 7, the larger the rotation angle is, the higher the content of the magnetic metal in the part 3 is, and when the rated value is reached, the pointer 7 can contact the contact 9 to switch on the electromagnet 17, so that the structure of the sorter 10 starts to work. The contact 9 can be moved freely in the arc groove 8, so that the effect of regulating the rated value can be achieved by changing the contact position of the pointer 7 and the contact 9.

Normally, two of the T-shaped channels 15 are aligned with the diversion port 13 and the conducting pipe 12 respectively, the third one is not aligned with the nozzle 11, and the high-pressure gas introduced into the conducting pipe 12 is introduced into the diversion port 13 through the T-shaped channel 15, so as to achieve the purpose of balancing the air pressure. When the electromagnet 17 starts to work, the electromagnet attracts the non-fixed position of the return spring 16, and simultaneously drives the rotary valve 14 to synchronously rotate in the counterclockwise direction as shown in fig. 3 to 4 until the rotary valve rotates to the limit position, at this time, the diversion port 13 is closed, the conduction pipe 12 is connected to the position of the nozzle 11, high-pressure gas is sprayed out from the position of the nozzle 11, and simultaneously, the target part 3 is blown down from the transmission belt 1, so that the effect of sorting the part 3 is achieved. When the part 3 leaves the induction position, the magnetic field change suffered by the magnetic field coil 5 disappears, the electromagnet 17 is turned off, and the return spring 16 drives the series of structures to return.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
