[0050] The present invention also provides a method of a municipal waste recycling device, comprising the following steps:

[0051] S1. Separation of iron waste

[0052] Add separation water into the first recovery box 2, and add construction waste into the processing box 1 through the hopper 11, and drive the flip plate 42 and the magnet bar 43 to rotate in a circle, the magnet bar 43 absorbs the iron waste in the construction waste, and the concrete waste and the wood waste are guided into the first recovery box 2 through the flip plate 42 and the L-shaped guide plate 44, and the wood waste floats on the liquid surface;

[0053] S2. Separation of wood waste

[0054] By driving the sleeve rod 52 and the L-shaped hook plate 53 to rotate in a circle, the L-shaped hook plate 53 enters the first recycling box 2, hooks the floating wood waste, and makes the wood waste fall onto the discharge bucket 55. The wood waste slides through the discharge bucket 55 into the second recycling bucket 32, and is then discharged from the second recycling bucket 32.

[0055] S3. Crushing of concrete waste

[0056] By driving the push seat 61 to move horizontally toward one side of the first recycling box 2, the push seat 61 pushes the concrete waste at the bottom of the first recycling box 2 into the first recycling bucket 31, and at the same time drives the two crushing rollers 82 to rotate synchronously toward the center direction of the first recycling bucket 31, and the two crushing rollers 82 crush the separated concrete waste.

[0057] Working principle: When construction waste needs to be recycled, the operator first adds the construction waste into the processing box 1 through the hopper 11, and the construction waste falls on the two flip plates 42, and the separation water is added into the first recycling box 2 at the same time;

[0058] At the same time, the operator turns on the servo motor 45, and the driving shaft of the servo motor 45 rotates through the first rotating rod 46 to rotate the fixed roller 41, and the fixed roller 41 causes the two flip plates 42 and the multiple magnet bars 43 to rotate in a circle, and the multiple magnet bars 43 absorb the iron waste in the construction waste. At the same time, the circular rotation of the two flip plates 42 causes the concrete waste and the wood waste to fall on the L-shaped guide plate 44. After being guided by the L-shaped guide plate 44, the concrete waste and the wood waste slide into the first recycling box 2, and the concrete waste falls on the bottom wall of the first recycling box 2, and the wood waste floats on the separation water;

[0059] At the same time, the first rotating rod 46 rotates the second rotating rod 57 through the two first synchronous wheels 58 and the first synchronous belt 59, and the second rotating rod 57 rotates the frame rod 51, and the frame rod 51 rotates the plurality of sleeve rods 52 and the plurality of L-shaped hook plates 53. When the plurality of L-shaped hook plates 53 enter the interior of the first recycling box 2, the plurality of L-shaped hook plates 53 hook the floating wood waste. As the plurality of L-shaped hook plates 53 rotate in a circle, the plurality of L-shaped hook plates 53 cause the wood waste to fall onto the discharge bucket 55, and the wood waste slides through the discharge bucket 55 into the second recycling bucket 32, and is then discharged through the second recycling bucket 32.

[0060] At the same time, the second rotating rod 57 rotates one of the rotating shafts 71 through the two second synchronous wheels 76 and the second synchronous belt 77. One rotating shaft 71 can make the other rotating shaft 71 rotate synchronously in the opposite direction through the two first gears 78. At this time, the two transmission belts 73 are in a synchronous reverse transmission state. The two transmission belts 73 move the two sets of first teeth 74. The two sets of first teeth 74 mesh with the transmission gear 75 in a staggered state and drive the transmission gear 75 to reciprocate. The transmission gear 75 makes the first transmission rod 68 reciprocate. The first transmission rod 68 rotates reciprocatingly through the two bevel gears 7 The lead screw 69 reciprocates, and the lead screw 69 causes the push seat 61 and the U-shaped rubber ring 62 to move horizontally toward one side of the first recycling box 2 through the moving seat 67, and then move horizontally in the opposite direction to reset. When the push seat 61 and the U-shaped rubber ring 62 move horizontally toward one side of the first recycling box 2, the push seat 61 pushes the concrete waste at the bottom of the first recycling box 2, and the concrete waste pushes the sealing door 65, and the sealing door 65 enters the second recycling box 3 through the second through-slot 623. When the pushed concrete waste is vertically aligned with the first recycling bucket 31, the concrete waste falls into the first recycling bucket 31;

[0061] At the same time, the first rotating rod 46 causes a third rotating rod 81 to rotate synchronously in the same direction through two fourth synchronous wheels 87 and a fourth synchronous belt 88, and a third rotating rod 81 causes a second transmission rod 83 to rotate synchronously in the same direction through two third synchronous wheels 84 and a third synchronous belt 85. The second transmission rod 83 causes another third rotating rod 81 to rotate synchronously in the opposite direction through the transmission of two second gears 86. At this time, the two third rotating rods 81 and the two crushing rollers 82 maintain a synchronous counter-rotating state, and the two crushing rollers 82 crush the concrete waste and discharge the crushed concrete waste downward through the first recovery bucket 31.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
