When a user stretches his hand to throw an object into the device, the infrared sensor 11 senses the information and sends a signal to the electric control switch 54 in the intelligent power supply 15 through the lead 13, the electric control switch 54 is closed to enable the high-voltage storage battery 55 to be short-circuited, the low-voltage storage battery 56 independently supplies power to the coil 14 in the forward direction, the iron core 12 and the coil 14 generate a magnetic field with the left side presenting as an N magnetic pole, and due to the magnetic field repulsion force between the N magnetic pole and the N magnetic pole, the left action door 5 and the right action door 45 are driven to do away actions along the first track 8 and the second track 10, so that the object throwing port 9 is automatically opened; when the object is not required to be put into the device, after the user finishes putting the object and retracts the hand, the infrared inductor 11 does not send a signal to the electric control switch 54 inside the intelligent power supply 15, the electric control switch 54 is switched off, so that the high-voltage storage battery 55 is not short-circuited, the high-voltage storage battery 55 and the low-voltage storage battery 56 supply power to the coil 14 together, the power supply current is reverse, the iron core 12 and the coil 14 generate a magnetic field with the left side presenting an S magnetic pole, and due to the magnetic field attraction between the N magnetic pole and the S magnetic pole, the left action door 5 and the right action door 45 are driven to do closing actions along the first track 8 and the second track 10, so that the automatic closing of the input port 9 is realized.

A driving roller 24 and a driven roller 31 are arranged on the lower side of the screening chamber 1 from left to right, a screening belt 26 is sleeved outside the driving roller 24 and the driven roller 31, and the screening belt 26 rotates around the driving roller 24 and the driven roller 31. The screening belt 26 is provided with screening holes 32, the contraction chamber 27 is arranged at the lower side of the screening belt 26, the left side surface of the screening chamber 1 is fixedly connected with the upper part of the connecting plate 19 through the first series of bolt groups 20, and the lower part of the connecting plate 19 is fixedly connected with the first auxiliary input chamber 21 through the first series of bolt groups 20. After the objects enter the screening chamber 1, the large-sized objects cannot pass through the screening holes 32 formed in the screening belt 26, and are conveyed to the first auxiliary input chamber 21 on the lower left side by the moving screening belt 26, and the large-sized objects are crushed by the large-sized blade group 46 fixed to the first power rotating shaft 22 in the first auxiliary input chamber 21. The small-sized objects continue to fall through the screening holes 32 formed in the screening belt 26, and then reach the second auxiliary input chamber 44 on the lower side through the contraction chamber 27, and are crushed by the small-sized blade group 28 fixed on the second auxiliary rotating shaft 29 in the second auxiliary input chamber 44.
