[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.

[0022] A device for automatically identifying and classifying dry and wet garbage, reference Figure 1-Figure 5 , comprising a garbage identification part 1. A dry garbage storage part 2 and a wet garbage storage part 3 are respectively arranged on the left and right sides of the garbage identification part 1. An energy storage component 6 is arranged on the upper side of the dry garbage storage part 2 and the wet garbage storage part 3. A garbage placement opening 11 is opened on the front side of the garbage identification part 1.

[0023] The dry garbage storage part 2 has a first opening 21 on one side close to the garbage identification part 1. The wet garbage storage part 3 has a second opening 31 on one side close to the garbage identification part 1. The dry garbage storage part 2 and the wet garbage storage part 3 both have a storage space 4 in communication with the openings.

[0024] A placement plate 12 is hingedly provided inside the garbage identification part 1. A push rod 14 is provided on the top wall inside the garbage identification part 1, which is located directly above the placement plate 12. A pin 13 is provided at the lower end of the push rod 14, and the push rod 14 pushes the pin 13 to move up and down. A resistive wet-dry sensor is provided on the pin 13. A first return spring 15 is provided at the lower left end of the placement plate 12, and a magnet 16 is provided at the lower right end. An electromagnet 17 is provided on the bottom wall inside the garbage identification part 1. The electromagnet 17 is opposite to the magnet 16. The electromagnet 17 is electrically connected to the resistive wet-dry sensor. A power module for supplying energy to the electromagnet 17 is provided inside the garbage identification part 1, and the power module, the resistive wet-dry sensor and the electromagnet 17 form a series circuit.

[0025] Under normal conditions, the power module supplies the electromagnet 17 with a certain current, and the magnetic attraction generated by the electromagnet 17 is balanced with the restoring force of the first reset spring 15, so that the placement plate 12 remains horizontal. When the user places the garbage on the placement plate 12, the push rod 14 extends, and the pin 13 is inserted into the garbage. If the garbage is wet garbage, the resistance of the resistive wet-dry sensor decreases, the current through the electromagnet 17 increases, and the magnetic attraction generated by the electromagnet 17 increases, pulling the placement plate 12 to rotate to the right end, the push rod 14 is retracted, and the pin 13 leaves the garbage, and the garbage is poured into the wet garbage storage part 3 under the action of its own weight; if the garbage is dry garbage, the resistance of the resistive wet-dry sensor increases, the current through the electromagnet 17 decreases, and the magnetic attraction generated by the electromagnet 17 is weakened. The restoring force of the first reset spring 15 pulls the placement plate 12 to rotate to the left end, the push rod 14 is retracted, and the pin 13 leaves the garbage, and the garbage is poured into the dry garbage storage part 2 under the action of its own weight.

[0026] The lower half of the storage space 4 is provided with a slide plate 42 for sealing and sliding up and down, and the upper half is provided with a pressure plate 41 for sealing and sliding. A screw rod 43 is provided on the lower side of the slide plate 42. A fourth return spring 47 is sleeved on the screw rod 43. The two ends of the fourth return spring 47 are respectively in contact with the slide plate 42 and the inner wall of the storage space 4. A first gear 44 is rotatably provided at the bottom of the storage portion. The first gear 44 is threadedly rotatably sleeved on the screw rod 43. A second gear 45 is meshedly provided on one side of the first gear 44. When garbage is thrown into the storage space 4, the gravitational potential energy of the falling garbage drives the slide plate 42 to slide up and down, thereby driving the first gear 44 to rotate, and then driving the second gear 45 to rotate.

[0027] A groove 81 is provided on the second gear 45. A turntable 82 is rotatably provided on the groove 81. A plurality of right-angled wedge-shaped openings 83 are evenly provided on the outer wall of the turntable 82. A second slide bar 84 matching the number and position of the right-angled wedge-shaped openings 83 is slidably penetrated through the inner wall of the groove 81. A right-angled wedge block 85 is provided at one end of the second slide bar 84 located in the groove 81. The right-angled wedge block 85 matches the shape and size of the right-angled wedge-shaped opening 83. Only the fourth return spring 47 is hit at one end of the second slide bar 84 located in the second gear 45. The fourth return spring 47 is connected to the inner wall of the second gear. The fourth return spring 47 is in a natural state, and the right-angled wedge block 85 is located at the right-angled wedge-shaped opening 83. When the slide plate 42 descends and drives the second gear 45 to rotate forward, the second gear 45 drives the turntable 82 to rotate; when the slide plate 42 rises and drives the second gear 45 to rotate forward, the second gear 45 cannot drive the turntable 82 to rotate.

[0028] The turntable 82 is connected to the connecting rod 7 in a transmission manner. The connecting rod 7 is connected to the input end of the energy storage assembly 6. The output end of the energy storage assembly 6 is connected to the cylinder 5 in a transmission manner. The cylinder 5 is rotatably arranged at the upper end of the storage portion. The outer wall of the cylinder 5 is provided with an annular groove 51 extending along the elongation direction thereof and connected end to end. A connecting rod 46 is slidably mounted on the slide groove 51. The connecting rod 46 is slidably arranged through the storage space 4, and the lower end is connected to the pressing plate 41. When the cylinder 5 rotates, the pressing plate 41 performs up and down reciprocating motion.

[0029] The energy storage assembly 6 includes a worm wheel 61 and a ratchet wheel 62 which are arranged in parallel. A torsion spring 63 is arranged between the worm wheel 61 and the ratchet wheel 62, and the two ends are connected to the two. A worm 64 is meshed on one side of the worm wheel 61. The worm 64 is the input end. The ratchet wheel 62 is transmission-connected to the cylinder 5 as the output end. The energy storage assembly 6 also includes a telescopic rod 65. A pawl 66 for limiting the rotation of the ratchet wheel 62 to one side is arranged at the end of the telescopic rod 65. Under normal conditions, the telescopic rod 65 is at its longest point, and the pawl 66 limits the rotation of the ratchet wheel 62, thereby limiting the energy release of the torsion spring 63. When there is too much garbage in the storage space 4, the telescopic rod 65 is started, the telescopic rod 65 is shortened to the shortest point, the pawl 66 releases the restriction on the rotation of the ratchet wheel 62, and the rotation of the ratchet wheel 62 drives the cylinder 5 to rotate, thereby driving the pressure plate 41 to reciprocate up and down.

[0030] The connecting rod 7 is rotatably connected to the lower end of the worm 64. A closed space 71 is provided in the worm 64. A plurality of notches 72 are evenly provided in an annular shape on the top wall of the closed space 71. A ball 73 is abutted in the notch 72. A first slide bar 74 is movably provided at the lower end of the ball 73. The first slide bar 74 slides through the worm 64 and the connecting rod 7. A second return spring 75 in a compressed state is sleeved on the first slide bar 74. The two ends of the second return spring 75 abut against the ball 73 and the inner wall of the closed space 71, respectively.

[0031] By setting the compression force of the second return spring 75, it is ensured that the energy stored in the torsion spring 63 can only supply the pressure plate 41 with one complete up and down reciprocating motion, thereby preventing the pressure plate 41 from blocking the opening when it stops, so that garbage cannot enter the storage space 4.

[0032] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above description or the technology or knowledge of the relevant field.
