Description

Technical Field

[0001] This utility model relates to the field of color sorting device technology, specifically a small soybean color sorting device. Background Technology

[0002] With the continued growth of global food trade, the number of imported food batches is large and the quantity of each batch is enormous. The need to quickly complete quarantine to ensure customs clearance efficiency and avoid cargo backlog is becoming increasingly urgent. Weed seeds are often mixed in with imported food. Weed quarantine of imported food is an important link in maintaining national agricultural ecological security and ensuring food production. In the quarantine work of imported food in customs plant quarantine laboratories and rapid screening rooms, foreign weed seeds have diverse forms (such as dodder and ragweed seeds that are similar in color and size to grain grains). Traditional manual sorting methods are inefficient, and relying on manual visual identification is prone to misjudgment. Moreover, the highly repetitive manual sorting work can easily lead to visual fatigue and distraction of quarantine personnel, further reducing the accuracy of detection. The limitations of manual operation can easily increase the risk of missed detection, which poses a threat to national biosecurity. However, existing small color sorting devices can efficiently process large sample volumes, accurately identify complex weed seeds, and reduce reliance on manual labor.

[0003] For example, CN209406877U discloses a small household color sorter, which includes a feeding hopper, a main unit, and a discharging hopper. The feeding hopper is installed at the top of the main unit. An electromagnetic spray valve is installed at the bottom of the main unit. A sorting box is installed in the middle of the main unit. LED light groups are installed at both ends of the sorting box. Cameras are installed on the top and bottom sides of the main unit, and both cameras face the sorting box. The sides of the sorting box facing the cameras are hollow. A camera circuit board is installed at the upper part of the main unit. A spray valve drive circuit board is installed at the bottom of the main unit. The camera circuit board is electrically connected to the operation screen, the camera, and the spray valve drive circuit board.

[0004] However, in customs quarantine scenarios, the waste removed during the color sorting process by color sorters includes two types of substances: target risk materials and ordinary impurities. Target risk materials, such as quarantine weed seeds like dodder and ragweed, are characterized by their invasiveness and high reproductive capacity. Ordinary impurities, such as broken shells and non-quarantine plant debris, are also present. During customs quarantine, target risk materials must be strictly isolated and destroyed according to biosafety procedures. Traditional color sorters use a single-path waste collection design, and after the two types of substances are mixed, they need to be manually sorted a second time to ensure that the target risk materials are handled in compliance with regulations. This not only increases the complexity of operation but may also lead to biosafety risks due to human contact or incomplete separation, making it difficult to meet the dual requirements of efficiency and safety for customs quarantine. Utility Model Content

[0005] The purpose of this invention is to provide a small soybean color sorting device to solve the problem that during customs quarantine, target risk materials need to be strictly isolated and destroyed according to biosafety procedures. Traditional color sorters use a single-path waste collection design, and after the two types of materials are mixed, manual secondary sorting is required to process the target risk materials in compliance with regulations, which increases the complexity of operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A small soybean color sorting device includes a housing, in which a first pulse air valve and a second pulse air valve are arranged in a staggered spatial layout. A first discharge channel is provided on the surface of the housing, and the first pulse air valve is used to spray ordinary impurities into the first discharge channel. A second discharge channel is provided on the surface of the housing, and the second pulse air valve is used to spray target hazardous materials into the second discharge channel. A third discharge channel is provided on the surface of the housing.

[0008] Preferably, the bottom of the housing is detachably connected to a hazardous material collection chamber, which is used to catch the target hazardous material.

[0009] Preferably, the bottom of the housing is fixedly connected with a vertically arranged docking pin, the top of the hazardous material collection chamber is provided with a docking slot for the docking pin to be inserted, the top surface of the hazardous material collection chamber is rotatably connected with a vertically arranged bolt assembly, and the bottom of the housing is provided with a threaded groove for the bolt assembly to be threaded.

[0010] Preferably, the bolt assembly includes a knob and a threaded rod, which are coaxially fixedly connected, and the knob portion protrudes from the side of the hazardous material collection compartment.

[0011] Preferably, the inner wall of the second discharge channel is rotatably connected to a control plate via a rotating shaft, the rotating shaft being located near the bottom of the control plate, and the control plate dividing the lower opening of the second discharge channel into two symmetrical sub-channels, and the number of the hazardous material collection bins is two.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The dual-channel separation design achieves precise separation of two types of substances. Independent first and second pulse air valves are set up to spray ordinary impurities and target risk substances into independent first and second discharge channels, respectively. This design avoids the mixing of the two types of waste from the source, significantly improves sorting efficiency, reduces biosafety risks, and provides an efficient solution for customs quarantine.

[0014] 2. The second discharge channel is divided into left and right sub-channels by the control plate. When one side of the collection bin is full, the control plate is driven to flip and automatically switch to the other side channel to receive material. The collection bin can be replaced without stopping the machine. The machine can be operated and replaced at the same time, avoiding the interruption of production capacity due to the emptying of the bin and improving the utilization rate of the equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution.

[0021] A small soybean color sorting device includes a housing 1, inside which a first pulse air valve 2 and a second pulse air valve 4 are arranged in a staggered spatial layout to ensure that the jet airflow does not interfere with each other. The first pulse air valve 2 is located above the second pulse air valve 4. A first discharge channel 3 is provided on the surface of the housing 1. The first pulse air valve 2 is used to spray the identified ordinary impurities into the first discharge channel 3 through airflow. A second discharge channel 5 is provided on the surface of the housing 1. The second pulse air valve 4 is used to spray the target hazardous material into the second discharge channel 5. A third discharge channel 12 is provided on the surface of the housing 1. The opening position of the first discharge channel 3 is higher than that of the second pulse air valve 4.

[0022] The bottom of the shell 1 is detachably connected to the risk material collection chamber 9, which is used to receive the target risk material. The risk material collection chamber 9 is specially designed for the target risk material, meets the biosafety isolation requirements, and is easy to handle in accordance with customs quarantine procedures. It forms a safety level distinction with the receiving methods of the first discharge channel 3 and the third discharge channel 12. The first discharge channel 3 and the third discharge channel 12 can be adapted to conventional receiving containers and methods, such as receiving boxes and grain collection bags, for collecting ordinary impurities and qualified soybeans. Its open receiving design meets the convenient handling needs of non-risk materials.

[0023] The bottom of the housing 1 is fixedly connected with a vertically arranged docking pin 7. The top of the hazardous material collection chamber 9 is provided with a docking slot 8 for the docking pin 7 to be inserted. The top surface of the hazardous material collection chamber 9 is rotatably connected with a vertically arranged bolt assembly. The bottom of the housing 1 is provided with a threaded groove for the bolt assembly to be threaded. Align the docking slot 8 of the hazardous material collection chamber 9 with the docking pin 7 of the housing 1, rotate the bolt assembly so that it is screwed into the threaded groove at the bottom of the housing 1, and achieve a rigid connection by locking through the thread pair.

[0024] The bolt assembly includes a knob 10 and a threaded rod 11, which are coaxially fixedly connected. The knob 10 is partially exposed on the side of the hazardous material collection chamber 9, and its outer periphery is provided with anti-slip texture or knurled structure, so that the operator can turn the knob 10 from the side to drive the threaded rod 11 to rotate, and screw it into and out of the threaded groove at the bottom of the housing 1 along the axis, so as to realize the quick locking or disassembly of the hazardous material collection chamber 9 and the housing 1.

[0025] The inner wall of the second discharge channel 5 is rotatably connected to a control plate 6 via a rotating shaft. The rotating shaft is located near the bottom of the control plate 6. The control plate 6 can be driven to rotate by a servo motor. The motor output shaft is coaxially fixed to the rotating shaft, which can control the swing of the control plate 6. The control plate 6 divides the lower opening of the second discharge channel 5 into two symmetrical sub-channels. There are two risk material collection bins 9, which respectively catch the risk materials falling from the two sub-channels. When the control plate 6 flips to the left and adheres to the left wall of the second discharge channel 5, the right sub-channel opens, and the target risk material falls into the right sub-channel. When the control plate 6 flips to the right and adheres to the right wall of the second discharge channel 5, the left sub-channel opens, and the target hazardous material falls into the left hazardous material collection bin 9 through the left sub-channel. When one side of the hazardous material collection bin 9 is full, the control plate 6 is driven by the motor to switch to the other side of the workstation without stopping the machine. Specifically, when the right side of the hazardous material collection bin 9 is full, the control plate 6 flips to the right to close the right sub-channel and open the left sub-channel at the same time. The target hazardous material is automatically switched to the left side of the hazardous material collection bin 9 for receiving. The original right side of the hazardous material collection bin 9 can be disassembled and replaced at the same time.

[0026] It also includes a feeding assembly, which consists of a feeding hopper, a vibrating feeder, and a guide trough. The bottom of the feeding hopper is connected to the vibrating feeder, and an inclined guide trough is set below the vibrating feeder. In the customs soybean quarantine scenario, after the soybean sample to be tested is poured into the feeding hopper, it falls into the vibrating feeder by gravity. The vibrating feeder uses electromagnetic vibration to uniformly and continuously transport the soybeans to the guide trough, so that the soybeans slide down the guide trough at a stable speed and spacing, forming a single-layer material flow.

[0027] It also includes an optical detection component, which comprises a light source module, an image acquisition module, and a detection cavity. The light source module uses a high-brightness, long-life LED linear light source, evenly distributed on both sides of the detection cavity. The image acquisition module uses a high-resolution color CCD camera to acquire clear images of soybeans and impurities. When soybeans enter the detection cavity from the guide channel, under the illumination of the LED light source, the light reflected from the surface of soybeans and impurities such as weed seeds is captured by the color CCD camera. Since soybeans and weed seeds, such as dodder and ragweed seeds, differ in color and hue, the camera converts these light signals into electrical signals and transmits them to the control system for image processing. The control system analyzes the image through a preset algorithm, identifies the boundaries and color characteristics of soybeans and impurities, and determines which are discolored particles such as weed seeds that need to be removed, reducing misjudgments caused by reliance on human experience.

[0028] Once the optical detection component identifies an impurity, the control system immediately sends a signal to the pneumatic control system. A high-speed airflow is then ejected from the corresponding pulse valve, blowing the impurity away from the normal soybean trajectory and causing it to fall into the impurity discharge port. Meanwhile, the qualified soybeans continue to move in the direction of free fall. This system automates the operation, eliminating the need for manual intervention and improving the accuracy and stability of sorting, thus addressing the issue of human fatigue caused by highly repetitive work.

[0029] The control system uses an industrial-grade PLC and is equipped with a touch screen human-machine interface. Operators can set various parameters through the touch screen, such as feeding speed, light source brightness, and airflow jet parameters. The control system also includes a data processing module, which is used to receive image data transmitted by the optical detection component and perform real-time processing and analysis.

[0030] The specific solution is as follows: In a customs soybean quarantine scenario, the soybean sample to be tested is poured into the feed hopper, the vibrating feeder is powered on, and the appropriate vibration frequency and amplitude are set through the control system. When the soybeans enter the detection chamber from the guide trough, the light reflected from the surface of the soybeans and impurities such as weed seeds is captured by a color CCD camera. The camera converts the light signal into an electrical signal, which is transmitted to the data processing module of the control system for image processing. The control system analyzes the image through a preset algorithm, identifies the boundaries and color characteristics of the soybeans and impurities, and determines the weed seeds and other discolored particles that need to be removed. The first pulse air valve 2 will then identify the... Ordinary impurities are sprayed into the first discharge channel 3 by airflow, and the second pulse air valve 4 sprays the target hazardous material into the second discharge channel 5. During the sorting process, the status of the hazardous material collection bin 9 is observed. When one side of the hazardous material collection bin 9 is fully loaded, such as the left side, the control plate 6 is driven to rotate. When the control plate 6 flips to the left and sticks to the left wall of the second discharge channel 5, the right sub-channel is opened. The target hazardous material falls into the right hazardous material collection bin 9 through the right sub-channel. The originally fully loaded hazardous material collection bin 9 can be disassembled and replaced at the same time. When replacing, rotate the bolt assembly and unscrew the threaded rod 11 to remove the hazardous material collection bin 9 downwards, so that the docking slot 8 is separated from the docking pin 7.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
