[0002] Garbage classification is an urgent need for environmental protection and garbage disposal. With the rapid development of the economy and the increase of urban population, the amount of domestic garbage generated is also growing continuously.

[0003] Garbage is mainly disposed of harmlessly through landfill and incineration.

[0004] In order to reduce the generation of pollutants and increase the resource value and economic value of garbage, garbage is sorted so that it can be accurately delivered to the appropriate treatment method to minimize secondary pollution.

[0040] Working method: In order to break the garbage bag so that the turntable and baffle will drop the garbage one by one into the conveyor belt below, the garbage bag breaking knife is equipped with four slender knives. After falling in, the two motors responsible for transmission are energized, and the gear drives the transmission shaft to move to the center position. Two knives on each side can pierce the garbage bag. The knives on both sides are synchronized to open outwards through the cooperation of the gears and the transmission shaft. The structure of the knives on both sides is similar. After breaking the garbage bag, the four knives retract and reset at the same time, which is realized by the reversal of the motor and PLC programming.

[0041] The turntable is tapered (high in the center and low around), with a small protrusion on the whole turntable and an opening (which can filter most of the kitchen waste, fine garbage, and liquid garbage). There is an opening at the connection between the turntable and the conveyor belt below, and there is a baffle in the opening that is consistent with the direction of the turntable's movement (there are bristles on the bottom of the baffle), (if the turntable rotates in a clockwise direction, the direction of the baffle is to the right, and with a certain angle, pointing to the center of the turntable) The baffle is connected to the leftmost side of the opening below, and the height is consistent with the height of the opening. After the garbage falls into the turntable, the garbage is arranged on the baffle and falls one by one into the conveyor belt below. The turntable has a slight contact with the conveyor belt, and the rotation speed of the turntable is lower than the transmission speed of the conveyor belt, so the garbage can be arranged one by one to pass through the recognition area of ​​the sensor.

[0042] The detection head is placed above the conveyor belt, and there is an infrared sensor in the middle of the detection gate. The infrared sensor can detect the type of garbage passing through the detection gate, such as recyclable and non-recyclable (the principle is: the sensor can detect the appearance of objects, such as rectangles, cylinders, cubes, etc.) When the detection is completed, it sends an electrical signal to the garbage picker behind it. When the recyclables reach the interval of the garbage picker, the picker moves to the left. Through the friction of the conveyor belt, the recyclables fall back into the recyclable collection bucket. On the contrary, for non-recyclables, the motor reverses, the picker moves to the right, and the non-recyclable garbage falls into the non-recyclable bucket.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
