Example Embodiment

[0025] The principle, structure and working process of the present invention will be further explained below with reference to the drawings.

[0026] The general principle of material classification and identification is: First, metal detectors are used to detect metals. Secondly, the external force forces the measured object to locally vibrate, and the detection of glass bottles and plastic bottles is realized by collecting and analyzing the fundamental frequency of the sound signal. The fundamental frequency characteristics of the material are: the fundamental frequency of the sound from striking glass is greater than 1.5kHz; the fundamental frequency of the sound from striking plastic is less than 1kHz. In addition, test objects that are easily compressed or too small are regarded as other garbage.

[0027] In order to realize the predetermined function and combine the principle of sound analysis, the mechanical part of the garbage classification actuator is divided into the fo...

Abstract

The invention discloses an automatically-classifying garbage bin belonging to the garbage classifying-recycling apparatus field. The automatically-classifying garbage bin utilizes a hall-sensor proximity switch for detecting metals, a mechanical knocking means for leading the detected matter to sound and a follow-up circuit for collecting and processing the sound signals so as to distinguish glasses, plastic and other varieties; simultaneously garbage with low recycling value of the garbage with less volume, plastic bags with better compressibility or paper bags and the like are all classified as the garbage of other varieties for disposal. The automatically-classifying garbage bin comprises a belt wheel, an optical bar, a mechanical frame, a low press plate, a connecting block, a linkage rod, a crank, a screw rod, a compressing plate, a conveying box, a knocking rod and an electromagnet. Compared with the existing art, the garbage bin has the advantages that the labor intensity for people is reduced; the recycling cost is saved; and the accuracy of garbage classification is enhanced.

Description

technical field [0001] The invention belongs to the field of garbage sorting and recovery devices, and in particular relates to a garbage can that automatically sorts garbage according to materials at a delivery source by means of electromechanical combination. Background technique [0002] There are mainly two types of garbage sorting and recycling. One is to centrally classify large quantities of garbage at the garbage dump. There are many impurities in large quantities of garbage, which makes it difficult to achieve accurate classification, and the cost of equipment is high and the volume is large. The second is to manually divide the garbage into several categories at the source of garbage disposal. This method requires the disposer to have high quality and common sense of garbage classification, and it also causes a lot of inconvenience to the disposer. [0003] The research situation of similar products at home and abroad is as follows. [0004] In September 2007, th...
