Description

Technical Field

[0001] The present invention belongs to the technical field of garbage disposal, and specifically relates to a garbage classification device and method thereof. Background Art

[0002] Currently, common garbage classification devices are mainly divided into three types: conveyor belt type, mechanical claw type, and rotary type. The conveyor belt type structure can stably achieve garbage classification, but the overall conveyor speed is slow, and it needs to pause and wait during classified storage to avoid misclassification of the garbage behind, resulting in low efficiency. The rotary type structure realizes garbage classification by driving the storage mechanism to rotate, but it cannot process multiple types of garbage simultaneously, and the garbage already placed will shake in the storage mechanism, affecting the classification effect. The mechanical claw type structure, when classifying multiple pieces of garbage simultaneously, grabs the garbage with mechanical claws and delivers it to the corresponding trash can. Its classification speed mainly depends on the moving speed of the XY-axis slide table, and the structure is compact, facilitating linkage with compression mechanisms, full-load detection mechanisms, etc., and is suitable for multi-task collaborative work. When identifying garbage, generally, a recognition camera takes pictures of the garbage and then analyzes and classifies the garbage. However, there are the following defects:

[0003] When classifying garbage, a recognition camera takes pictures of the garbage, and then after parsing the garbage pictures, the garbage is classified. However, when performing garbage classification, only one garbage type recognition is performed, which is likely to cause inaccurate garbage classification. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present invention provides a garbage classification device and method thereof, effectively solving the problem that only one garbage type recognition is performed during garbage classification, which is likely to cause inaccurate garbage classification.

[0023] 2) During operation, when the garbage is placed in the correct position, the toothed ring rotates rapidly relative to the turning plate, so that the pressing block arranged inside the toothed ring continuously presses the pressing ball, causing the mouth-shaped plate to reciprocate, thereby driving the two baffle cutting knives to open and close rapidly. When the garbage enters the garbage storage cavity from the garbage pre-storage cavity, the garbage is cut and broken, facilitating subsequent compression of the garbage.

[0024] 3) During operation, when the electromagnet generates an attractive force on the magnetic block, the clamping rod is clamped with the lower card slot and disengaged from the upper card slot, so that the turning plate is fixed to the garbage storage cavity and separated from the toothed ring. The toothed ring rotates to make the baffle cutting knife open and close reciprocally for crushing. When the electromagnet generates a repulsive force on the magnetic block, the clamping rod is clamped with the upper card slot and disengaged from the lower card slot, so that the turning plate is fixed to the toothed ring and separated from the garbage storage cavity, enabling the turning plate to rotate to transfer the garbage, facilitating garbage classification.

Detailed implementation manners

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figures 1-11 shown, the present invention relates to a garbage classification device, including a frame 1. A garbage classification component 6 is provided at the bottom of the inner cavity of the frame 1. A feeding port 2 is opened at the top end of the frame 1. A four-side opening and closing mechanism 3 is provided below the feeding port 2. The four-side opening and closing mechanism 3 is located above the garbage classification component 6. A two-axis slide 5 is provided above the four-side opening and closing mechanism 3. The two-axis slide 5 is installed on the inner top wall of the frame 1. The two-axis slide 5 is used to drive the telescopic claw 4 to move. A first recognition camera is installed on the telescopic claw 4. The first recognition camera is used to perform the first recognition on the garbage.

[0041] The garbage classification component 6 includes a garbage storage member 7 below and a garbage transfer member 8 above. The garbage transfer member 8 can perform secondary recognition on the classified garbage. The garbage storage member 7 includes a lower cross plate 701 fixedly installed at the bottom of the inner cavity of the frame 1. Four garbage storage cavities 702 are separated on the lower cross plate 701. A garbage compression mechanism 703 is provided in one of the garbage storage cavities 702. Four lower card slots 704 are equiangularly opened at the top end of the lower cross plate 701. The four garbage storage cavities are respectively used to store the following four types of garbage: recyclable garbage except glass, harmful garbage such as worn-out batteries, kitchen waste, and other garbage. The garbage storage cavity 701 where the garbage compression mechanism 703 is provided is used to store recyclable garbage except glass. Recyclable garbage except glass is generally book paper, plastic bottles, and metal cans. The garbage compression mechanism 703 compresses this part of the garbage to increase the garbage storage capacity in the garbage storage cavity 701.

[0042] The garbage transfer member 8 includes a rotating plate 801 rotatably installed above the lower cross plate 701. The top end of the rotating plate 801 is provided with an upper cross plate 802. The upper cross plate 802 divides the top end of the rotating plate 801 into four garbage pre-storage cavities 803. A rotating drive unit 805 for driving rotation is arranged on the rotating plate 801. Garbage passing units 806 are arranged on each of the garbage pre-storage cavities 803. Four second recognition cameras 804 are equiangularly arranged on the inner wall of the frame 1. The four second recognition cameras 804 are respectively located above the four garbage pre-storage cavities 803 and are used for secondary recognition of the garbage entering the garbage pre-storage cavities 803. The lower cross plate 701 is divided into four garbage storage cavities 702 corresponding to four types of garbage, and the upper cross plate 802 is divided into four garbage pre-storage cavities 803. The first recognition camera on the telescopic claw 4 and the second recognition camera 804 respectively perform the first recognition and the second recognition on the garbage, making the garbage classification more accurate. At the same time, by rotating the rotating plate 801, the garbage pre-stored in one of the garbage pre-storage cavities 803 can be brought above the corresponding garbage storage cavity 702 for discharging, facilitating garbage classification.

[0043] The rotating drive unit 805 includes an annular groove 8051 formed on the outer side of the rotating plate 801. A toothed ring 8052 is arranged inside the annular groove 8051. One side of the toothed ring 8052 is meshed with a gear 8053. The gear 8053 is fixedly connected to the output shaft of the motor 8054. The motor 8054 is fixedly installed on the frame 1.

[0044] The waste passing unit 806 includes a blanking chute 8061 formed in the bottom wall of the waste pre-storage cavity 803. The top wall of the rotating plate 801 is inclined downward near the blanking chute 8061. The internal slots 8062 are equally angled inside the rotating plate 801. The internal slots 8062 correspond to the waste pre-storage cavities 803 one by one. Two material blocking and cutting knives 8063 are symmetrically arranged inside the internal slots 8062. The two material blocking and cutting knives 8063 close the blanking chute 8061. Connecting arms 8064 are installed on one side of the material blocking and cutting knives 8063 close to the axis of the rotating plate 801. One end of the connecting arm 8064 is rotatably installed outside the fixed shaft 8065. The fixed shaft 8065 is fixedly installed inside the internal slot 8062. A limiting slot 8066 is formed in the connecting arm 8064. A limiting rod 8067 is slidably installed inside the limiting slot 8066. The top end of the limiting rod 8067 is installed with a slider 8068. The slider 8068 is slidably installed inside the chute 80611. The chutes 80611 are symmetrically formed in the bottom wall of the waste pre-storage cavity 803, and the chutes 80611 are perpendicular to the limiting slots 8066. A longitudinal moving block is arranged inside the waste pre-storage cavity 803. The bottom end of the longitudinal moving block is symmetrically hinged with two first connecting rods 80610. The bottom ends of the two first connecting rods 80610 are respectively hinged with the two sliders 8068. Four longitudinal sliding slots 80612 are equally angled on the upper cross plate 802. An L-shaped plate 8069 is arranged above the rotating plate 801. The L-shaped plate 8069 is slidably connected with the four longitudinal sliding slots 80612. And the four longitudinal moving blocks are respectively fixedly installed at the four corners of the L-shaped plate 8069. A cutting driving unit 807 is installed on the L-shaped plate 8069. The function of the material blocking and cutting knife 8063 is to cut the waste. However, the sharpness of the material blocking and cutting knife 8063 is relatively low. Generally, it can only open the plastic bottles, aluminum cans, etc. to release the air inside the plastic bottles and aluminum cans, which is convenient for subsequent compression. But it cannot damage the outer shells of harmful wastes such as waste batteries to avoid causing harm. And since only the plastic bottles, aluminum cans, etc. need to be opened, the reciprocating opening and closing frequency and speed of the material blocking and cutting knife 8063 are relatively slow, further reducing the damage to harmful wastes.

[0045] The cutting drive unit 807 includes a transverse sliding groove 8071 formed on the side of the longitudinal sliding groove 80612 away from the central axis of the rotating plate 801. The bottom end of the transverse sliding groove 8071 penetrates into the interior of the rotating plate 801. A transverse sliding plate 8072 is slidably installed inside the transverse sliding groove 8071. A second spring 8073 is hingedly installed on the side of the transverse sliding plate 8072 close to the square plate 8069. The other end of the second spring 8073 is hingedly installed with the square plate 8069. A second connecting rod 8074 is installed on the side of the transverse sliding plate 8072 close to the longitudinal sliding groove 80612. One end of the second connecting rod 8074 is fixedly connected to the inner wall of the transverse sliding groove 8071. A rod groove 8075 is formed on the side of the transverse sliding groove 8071 away from the longitudinal sliding groove 80612. One end of the rod groove 8075 penetrates into the interior of the annular groove 8051. A pressure rod 8076 is movably installed inside the rod groove 8075. One end of the pressure rod 8076 is fixedly connected to the transverse sliding plate 8072. A pressure ball 8077 is installed at one end of the pressure rod 8076. The pressure ball 8077 is located inside the annular groove 8051. An annular empty groove 8078 is formed inside the toothed ring 8052. The annular empty groove 8078 is communicated with the inner side of the toothed ring 8052. Pressure blocks 8079 are installed at equal angles inside the annular empty groove 8078. A clamping control unit 808 is arranged at equal angles below the toothed ring 8052. When the garbage is placed in the correct position, the toothed ring 8052 rotates rapidly relative to the rotating plate 801, so that the pressure blocks 8079 arranged on the inner side of the toothed ring 8052 continuously press the pressure ball 8077, causing the square plate 8069 to reciprocate, thereby driving the two baffle cutting knives 8063 to open and close rapidly. When the garbage enters the garbage storage cavity 702 from the garbage pre-storage cavity 803, the garbage is cut and broken, which is convenient for subsequent compression of the garbage.

[0046] The clamping control unit 808 includes four upper clamping grooves 8088 equally angularly provided at the bottom end of the gear ring 8052. The four upper clamping grooves 8088 are respectively located above the four lower clamping grooves 704. Activity grooves 8081 are equally angularly provided inside the rotating plate 801. The activity grooves 8081 are located between the lower clamping grooves 704 and the clamping control unit 808. Through grooves 8082 are provided on both the upper and lower sides of the activity grooves 8081. The upper through groove 8082 communicates with the annular groove 8051, and the lower through groove 8082 penetrates to the bottom of the rotating plate 801. An activity plate 8084 is slidably installed inside the activity grooves 8081. A clamping rod 8083 is installed on the activity plate 8084. The two ends of the clamping rod 8083 are respectively clamped into the upper clamping grooves 8088 and the lower clamping grooves 704. A third spring 8085 is installed at the bottom end of the activity plate 8084. The bottom end of the third spring 8085 is fixedly connected to the bottom wall of the activity groove 8081. A magnetic block 8086 is installed on the activity plate 8084. An electromagnet 8087 is installed on the inner bottom wall of the activity groove 8081. When the electromagnet 8087 generates an attractive force on the magnetic block 8086, the clamping rod 8083 is clamped with the lower clamping groove 704 and disengaged from the upper clamping groove 8088, so that the rotating plate 801 is fixed to the garbage storage cavity 702 and separated from the gear ring 8052. The rotation of the gear ring 8052 causes the material blocking and cutting knife 8063 to reciprocate and open and close for crushing. When the electromagnet 8087 generates a repulsive force on the magnetic block 8086, the clamping rod 8083 is clamped with the upper clamping groove 8088 and disengaged from the lower clamping groove 704, so that the rotating plate 801 is fixed to the gear ring 8052 and separated from the garbage storage cavity 702, so that the rotating plate 801 rotates to transfer the garbage, facilitating garbage classification.

[0047] Working principle: During operation, first, the garbage is put into the four-side opening and closing mechanism 3 from the feeding port 2. The garbage is identified by the first identification camera on the telescopic clamping jaw 4. After the identification is completed, the telescopic clamping jaw 4 clamps the garbage. The telescopic clamping jaw 4 is driven by the two-axis sliding table 5 to move, so that the telescopic clamping jaw 4 moves to the upper part of the garbage storage cavity 702 corresponding to the garbage. Then, the four-side opening and closing mechanism 3 is opened, and the telescopic clamping jaw 4 is opened to drop the garbage. At this time, the garbage falls into the garbage pre-storage cavity 803 above the garbage storage cavity 702 corresponding to the garbage;

[0048] At this time, the second recognition camera 804 performs a second recognition on the garbage that has fallen into the garbage pre-storage cavity 803. At this time, both ends of the clamping rod 8083 are respectively clamped into the upper clamping groove 8088 and the lower clamping groove 704 for clamping connection, so as to clamp and fix the rotating plate 801, the lower cross plate 701, and the gear ring 8052. When the second recognition finds that the garbage throwing position is correct, control the electromagnet 8087 to conduct positive electricity, so that the electromagnet 8087 generates an attractive force on the magnetic block 8086, driving the clamping rod 8083 to move downward, so that the bottom end of the clamping rod 8083 moves deeper into the lower clamping groove 704. At the same time, the clamping rod 8083 is disengaged from the upper clamping groove 8088, so that the rotating plate 801 is clamped with the lower clamping groove 704 and the gear ring 8052 is disengaged from the rotating plate 801. At this time, the motor 8054 is started, so that the gear 8053 rotates, driving the gear ring 8052 to rotate, so that the pressing block 8079 inside the gear ring 8052 continuously generates pressure on the pressing ball 8077 at the end of the pressing rod 8076. When the pressing block 8079 generates pressure on the pressing ball 8077, it pushes the pressing rod 8076 to move toward the side of the longitudinal sliding groove 80612, and pushes the square plate 8069 downward through the second spring 8073. Then, the slider 8068 is pushed to move along the sliding groove 80611 through the first connecting rod 80610, so that the two material blocking and cutting knives 8063 are opened. After the pressing block 8079 is separated from the pressing ball 8077, under the elastic force of the second connecting rod 8074, the square plate 8069 moves upward and returns, so that the two material blocking and cutting knives 8063 are closed, so that the two material blocking and cutting knives 8063 reciprocally open and close, so that the garbage falls from the blanking groove 8061, and after the two material blocking and cutting knives 8063 reciprocally open and close, the garbage is crushed, which is convenient for subsequent compression of the garbage. After processing, the gear ring 8052 is rotated to the position where the upper clamping groove 8088 corresponds to the lower clamping groove 704 one by one;

[0049] When the second recognition finds that the garbage throwing position is incorrect, by passing a reverse current through the electromagnet 8087, a repulsive force is generated on the magnetic block 8086, pushing the clamping rod 8083 to move upward, so that the movable plate 8084 enters deep into the upper clamping groove 8088, and the upper clamping groove 8088 is disengaged from the lower clamping groove 704, so that the rotating plate 801 is separated from the lower clamping groove 704, and the gear ring 8052 is clamped and fixed with the rotating plate 801. At this time, the rotating plate 801 is driven to rotate by the motor 8054, so that the garbage pre-storage cavity 803 storing garbage rotates to the upper part of the corresponding garbage storage cavity 702. After rotation, control the electromagnet �087 to power off, so that the clamping rod 8083 moves back, so that the rotating plate 801, the lower cross plate 701, and the gear ring 8052 are clamped and fixed with each other, and then the operation when the second recognition finds that the garbage throwing position is correct can be performed;

[0050] When it is necessary to cut the garbage, a large current is passed through the motor 8054 to make the gear 8053 rotate rapidly, so that the reciprocating opening and closing frequency of the baffle cutting knife 8063 is fast, which is convenient for cutting. When it is necessary to drive the garbage to move, a small current is passed through the motor 8054 to make the rotating plate 801 rotate slowly, which is convenient for stable garbage transfer.
