[0002] Edible fungi such as button mushrooms, shiitake mushrooms, straw mushrooms, and oyster mushrooms are generally graded in three levels. Taking shiitake mushrooms as an example: Level 1: Cap diameter 5.5–7 cm, round and intact, normal brown color; stem length not exceeding the cap radius, neatly trimmed; no insect damage, no broken mushrooms; Level 2: Cap diameter 4.5–5.4 cm, round and intact, normal color; stem length not exceeding the cap radius; no insect damage, no broken mushrooms; Level 3: Cap diameter 3–4.4 cm, round and intact, normal color; stem length not exceeding the cap radius; no insect damage, a small number of broken mushrooms are allowed.

[0003] In the actual grading process of shiitake mushrooms, a multi-stage sieving method using vibrating screens is generally adopted, separating the mushrooms according to the different aperture sizes of the screen plates. During the sieving process, due to the vibration and the weight of the mushrooms themselves, smaller mushrooms are distributed below larger ones. Since the aperture size of the screen plate is fixed, the continuous vibration of mushrooms of different sizes may cause blockage of the screen apertures, affecting the sieving efficiency and accuracy.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a multi-stage sorting device for edible fungi production and processing, such as... Figure 1-3As shown, the multi-stage sorting device for edible fungi production and processing includes: a sorting box 1; a partition 2, the partition 2 being fixedly installed on the sorting box 1; a feed hopper 3, the feed hopper 3 being fixedly installed on the partition 2; three screening mechanisms, all three of which are disposed within the sorting box 1 for grading and screening edible fungi, the screening mechanisms being correspondingly arranged with the feed hopper 3; three transport mechanisms, all three of which are disposed within the sorting box 1 for discharging the screened edible fungi, the three transport mechanisms being correspondingly arranged with the three screening mechanisms; and an anti-clogging mechanism, disposed on the sorting box 1 for separating edible fungi that are blocked on the screening mechanisms.

[0021] In this embodiment, the sorting box 1 serves as the main structure of the entire grading device. It provides space for the installation and operation of screening, transportation, and anti-clogging mechanisms, ensuring the orderly progress of the entire grading process. A partition 2 with a feed hopper 3 acts as a divider and guide, allowing the edible fungi to enter the screening mechanism in an orderly manner, avoiding chaos and cross-contamination. The feed hopper 3, as the entry point for the edible fungi into the grading system, should be rationally designed to ensure the fungi fall smoothly into the screening mechanism below. Three screening mechanisms are all located within the sorting box and corresponding to the feed hoppers, used for the grading and screening of edible fungi. Through sieves of different apertures and a vibrating screening method, the edible fungi are divided into first, second, and third grades according to size. The design of the screening mechanism should ensure accurate grading and ease of maintenance and cleaning. The transportation mechanism is used to promptly discharge the edible fungi of each grade from the sorting box, avoiding accumulation and confusion. The transportation mechanism should be designed to be efficient and stable, ensuring that the edible fungi are not damaged during transportation. Considering the potential sieve clogging problem in traditional screening processes, this patent specifically designs an anti-clogging mechanism. Installed on the sorting box, this mechanism effectively separates edible fungi clogging the screening mechanism through airflow impact, thereby restoring screening efficiency and accuracy. The application of the anti-clogging mechanism significantly improves the reliability and production efficiency of the equipment. Through multi-stage screening and an optimized transport mechanism, rapid and accurate grading of edible fungi is achieved. The innovative anti-clogging mechanism effectively prevents sieve hole clogging, ensuring the continuity and stability of the screening process. The overall structural design is reasonable, easy to maintain and clean, and extends the service life of the equipment.

[0022] In a further preferred embodiment of the present invention, the screening mechanism includes a plurality of drive rollers 4, a screen 5 and a first tensioning wheel 6. The plurality of drive rollers 4 are rotatably mounted inside the sorting box 1. The screen 5 is sleeved on the plurality of drive rollers 4. The first tensioning wheel 6 is rotatably mounted inside the sorting box 1 and abuts against the screen 5.

[0023] In this embodiment, multiple drive rollers 4 serve as the main support and driving components of the screen 5. The rotation of the drive rollers 4 drives the screen 5 in a cyclical motion, achieving the sieving of edible fungi. The arrangement of multiple drive rollers 4 ensures the stability of the screen and the sieving effect. The screen 5 is a key component for achieving the grading and screening of edible fungi. The aperture size of the screen is set according to the grading requirements. Through the vibration and cyclical motion of the screen, edible fungi of different sizes are separated. The first tensioning wheel 6 adjusts the tension of the screen, ensuring that the screen remains flat and stable during rotation, avoiding the impact on the sieving effect due to slackness or excessive tension. Simultaneously, the tensioning wheel can also reduce screen wear to a certain extent, extending its service life. Through the coordinated work of multiple drive rollers, the screen can achieve faster and more stable cyclical motion, thereby improving sieving efficiency. The flatness and stability of the screen are crucial to ensuring sieving accuracy. The design of the first tensioning wheel effectively guarantees the tension of the screen, avoiding sieving errors caused by screen deformation.

[0024] In a further preferred embodiment of this utility model, the transport mechanism includes a discharge port 7, a collection trough 8, two rotating rollers 9, a conveyor belt 10, and a drive motor 11. The discharge port 7 is opened on the side wall of the sorting box 1. The collection trough 8 is fixedly installed inside the sorting box 1 and is arranged between the plurality of drive rollers 4 and the screen 5. The collection trough 8 extends to the outside of the sorting box 1 through the discharge port 7. The two rotating rollers 9 are rotatably installed inside the collection trough 8. The conveyor belt 10 is sleeved on the two rotating rollers 9. The drive motor 11 is fixedly installed on the collection trough 8, and the output shaft of the drive motor 11 is fixedly connected to any of the rotating rollers 9.

[0025] In this embodiment, the discharge port 7 is located on the side wall of the sorting box 1, serving as the outlet for the edible fungi after screening. Its position and size need to be rationally determined based on the design of the screening mechanism and the collection trough to ensure smooth discharge of the edible fungi. The collection trough 8 temporarily stores the edible fungi that fall from the screen and guides them to the discharge port. Its design needs to consider factors such as capacity and inclination angle to ensure that the edible fungi can smoothly slide to the discharge port. Two rotating rollers 9 serve as the support and drive components for the conveyor belt 10. The rotation of the rotating rollers 9 drives the conveyor belt in a cyclical motion, thereby transporting the edible fungi in the collection trough to the designated location. The conveyor belt 10 is a key component for realizing the transport of edible fungi. The conveyor belt should have sufficient width and strength to carry and transport the screened edible fungi. The drive motor 11 provides power to the rotating rollers, driving them to rotate, which in turn drives the conveyor belt in a cyclical motion. Through the coordinated work of the rotating rollers and the conveyor belt, rapid and stable transport of the screened edible fungi is achieved. This helps reduce the residence time of the edible fungi in the sorting box and improves overall production efficiency. The collection trough is designed to allow the screened edible fungi to fall into it in an orderly manner and be temporarily stored before being transported to a designated location by a conveyor belt. This process optimizes the collection of edible fungi and reduces human intervention and errors. The transport mechanism works closely with the screening mechanism to achieve a seamless connection between screening and collection of edible fungi. All parts of the entire sorting system work together, enhancing overall coordination and stability.

[0026] In a further preferred embodiment of this utility model, the anti-clogging mechanism includes three identification cameras 12, a fan 13, a connecting pipe 14, three T-pipes 15, three exhaust pipes 16, and three solenoid valves 17. The three identification cameras 12 are all fixedly mounted on the partition 2 and are respectively arranged corresponding to the three screens 5. The fan 13 is fixedly mounted on the sorting box 1. The connecting pipe 14 is fixedly mounted on the exhaust end of the fan 13. The three T-pipes 15 are all fixedly mounted on the connecting pipe 14. The three exhaust pipes 16 are respectively fixedly mounted on the three T-pipes 15 and extend below the three screens 5, respectively, and are respectively arranged corresponding to the three identification cameras 12. The three solenoid valves 17 are respectively fixedly mounted on the three exhaust pipes 16 and are respectively arranged corresponding to the three identification cameras 12.

[0027] In this embodiment, the identification camera 12 is responsible for real-time monitoring of the screen's working status, particularly detecting whether edible fungi are clogging the screen holes. Its high precision and real-time performance provide a reliable basis for subsequent anti-clogging measures. The fan 13 serves as the airflow generator. When the identification camera detects a blockage, the fan will start, generating a powerful airflow to disperse the clogging edible fungi. The connecting pipe 14 is used to guide the airflow generated by the fan to each screen area. Three T-pipes 15 are fixedly installed on the connecting pipe 14, serving a diversion function. They evenly distribute the airflow from the fan to the three exhaust pipes 15, ensuring that each screen area receives sufficient airflow. The exhaust pipe 16 is responsible for blowing the airflow directly under the screen to effectively remove the clogging edible fungi. The solenoid valve 17 serves as a control element, controlling the opening and closing of the exhaust pipe according to the signal from the identification camera. When the identification camera detects a blockage, the corresponding solenoid valve will open, allowing airflow; conversely, it will close to save energy. Through the coordinated operation of the identification camera and the solenoid valve, intelligent detection and handling of screen blockage are achieved. This significantly improves the efficiency and accuracy of anti-clogging, reducing the need for manual intervention. The powerful airflow generated by the blower can quickly disperse the edible fungi clogging the screen, restoring the screen's normal screening function. This helps maintain the continuity and stability of the screening process. Precise control of the solenoid valve ensures that airflow is released under the screen only when needed, thus avoiding unnecessary energy waste. This helps reduce equipment operating costs and minimize environmental impact.

[0028] In a further preferred embodiment of this utility model, the sorting box 1 is provided with a driving mechanism for driving the three screening mechanisms to operate. The driving mechanism includes three driving gears 18, a chain 19, two second tensioning wheels 20, and a driving motor 21. The three driving gears 18 are respectively fixedly installed on the three driving rollers 4 in the three screening mechanisms. The chain 19 is sleeved on the three driving gears 18. The two second tensioning wheels 20 are rotatably installed on the sorting box 1 and abut against the chain 19. The two second tensioning wheels 20 are respectively arranged between two adjacent driving gears 18. The driving motor 21 is fixedly installed on the sorting box 1, and the output shaft of the driving motor 21 is fixedly connected to any one of the driving gears 18.

[0029] In this embodiment, the three drive gears 18, as key components in the transmission chain, transmit the power of the drive motor to each drive roller, thereby driving the screen to circulate. A chain 19 is fitted onto the three drive gears 18, forming a closed transmission chain. The chain 19 is responsible for transmitting the power of the drive motor 21 from one drive gear to another, ensuring that the three screening mechanisms can operate synchronously. The two second tensioning pulleys 20 adjust the chain tension, preventing the chain from becoming slack or overly tight during transmission, thus ensuring the smoothness and reliability of the transmission. The drive motor 21 is the power source of the entire drive mechanism, rotating its output shaft to drive the connected drive gears to rotate, thereby starting the entire transmission chain. Through the design of the drive mechanism, centralized driving and synchronous operation of the three screening mechanisms are achieved. This greatly improves the automation level and operating efficiency of the equipment, reducing energy consumption and costs caused by individual drives. Chain drive has advantages such as simple structure, smooth transmission, and low noise. At the same time, the design of the second tensioning pulleys further ensures the chain tension, reduces vibration and wear during transmission, and improves the reliability and service life of the equipment. The drive mechanism, screening mechanism, and transport mechanism work together to form a complete edible fungus grading and screening system. Centralized drive and synchronous operation enhance the coordination and stability of the entire system, improving the efficiency and accuracy of edible fungus grading and screening.

[0030] In a further preferred embodiment of this utility model, the sorting box 1 is provided with three vibration mechanisms for driving the three screens 5 to vibrate. Each vibration mechanism includes two movable grooves 22, a crossbar 23, a support frame 24, multiple springs 25, and a reciprocating mechanism. The two movable grooves 22 are respectively opened on both sides of the sorting box 1. The crossbar 23 is slidably disposed between the two movable grooves 22. The crossbar 23 is disposed between the multiple drive rollers 4 and the screens 5 and abuts against the bottom of the screens 5. The support frame 24 is disposed on the sorting box 1 and rotatably connected to the crossbar 23. The multiple springs 25 are fixedly installed between the partition 2 and the support frame 24. The reciprocating mechanism is disposed on the partition 2 and is used to drive the support frame 24 to perform reciprocating motion.

[0031] In this embodiment, two movable slots 22 are respectively opened on both sides of the sorting box, providing space for the sliding of the crossbar. The design of the movable slots must ensure that the crossbar can slide smoothly within them while maintaining a certain degree of stability. The crossbar 23 abuts against the bottom of the screen. When the crossbar moves, it can cause the screen to vibrate, which helps to screen edible fungi and prevent clogging. The support frame 24 provides stable support for the crossbar and allows it to reciprocate. The design of the support frame must consider its strength and stability to withstand the force when the crossbar moves. The function of the spring 25 is to provide elastic support for the support frame, so that the support frame can deform to a certain extent when subjected to external force, thereby causing the crossbar and screen to vibrate. The number and stiffness of the springs need to be adjusted according to actual needs to achieve the best vibration effect. The reciprocating mechanism is used to drive the support frame to reciprocate. The reciprocating mechanism is the power source of the vibration mechanism, and its design must ensure that it can stably and reliably drive the support frame to reciprocate, thereby realizing the vibration of the screen. Through the action of the vibration mechanism, the screen can generate continuous shaking, which helps to disperse and screen edible fungi. This reduces the accumulation and clogging of edible fungi on the screen, improving screening efficiency. The shaking of the screen allows the edible fungi to be distributed more evenly during the screening process, reducing screening errors caused by accumulation. At the same time, the shaking also helps to shake off the edible fungi adhering to the screen, further improving the accuracy of screening.

[0032] In a further preferred embodiment of this utility model, the reciprocating mechanism includes a fixed frame 26, a rotary motor 27, a turntable 28, an eccentric shaft 29, and a traction rope 30. The fixed frame 26 is fixedly installed on the partition plate 2, the rotary motor 27 is fixedly installed on the fixed frame 26, the turntable 28 is fixedly installed on the output shaft of the rotary motor 27, the eccentric shaft 29 is fixedly installed on the turntable 28, and the traction rope 30 is fixedly installed on the top of the support frame 24. The other end of the traction rope 30 is connected to the eccentric shaft 29.

[0033] In this embodiment, the mounting bracket 26 provides a stable mounting foundation for the rotary motor and other components. The bracket design must ensure its robust structure to withstand the vibrations and forces generated by the rotary motor and turntable during operation. The rotary motor 27 is the power source for the reciprocating mechanism. By rotating its output shaft, it drives the turntable and eccentric shaft to rotate, thereby realizing the reciprocating motion of the traction rope. The turntable 28 rotates with the motor. The turntable design must consider its balance and rotational smoothness to ensure that the eccentric shaft does not generate excessive vibration and noise during rotation. The axis of the eccentric shaft 29 does not coincide with the center of the turntable, thus generating centrifugal force during rotation. The eccentric shaft is connected to the traction rope, and the centrifugal force generated by its rotation drives the reciprocating motion of the traction rope. The traction rope 30, as a transmission element, converts the rotational motion of the eccentric shaft into the reciprocating motion of the support frame. The traction rope must have sufficient strength and flexibility to withstand the tension and bending during movement. Through the coordinated action of the rotary motor, turntable, and eccentric shaft, the reciprocating motion of the traction rope is realized. This simple yet effective design ensures the stability and reliability of the support frame and screen during long-term operation. The reciprocating motion of the support frame causes the screen to vibrate, which helps to disperse and screen the edible fungi. This vibration effect reduces the accumulation and clogging of edible fungi, improving screening efficiency. Compared to other complex mechanical vibration methods, the reciprocating mechanism of this invention achieves the screen vibration function through simple rotation and reciprocating motion, reducing energy consumption and noise generation.

[0034] In summary, compared with related technologies, this device, by integrating an anti-clogging mechanism, a drive mechanism, and a vibration mechanism, achieves high efficiency, accuracy, and automation in the overall grading and screening of edible fungi. Specifically, the anti-clogging mechanism uses a recognition camera to monitor the screen clogging status in real time and controls the fan and solenoid valve to promptly clear blockages, effectively preventing screen clogging and ensuring the continuity and stability of the screening process. The drive mechanism, through chain transmission and a drive motor, achieves centralized driving and synchronous operation of multiple screening mechanisms, improving the automation level and operating efficiency of the equipment. The vibration mechanism, through a reciprocating mechanism, drives the screen to vibrate, promoting the dispersion and screening of edible fungi on the screen, further improving screening efficiency and accuracy. This device not only solves the problems of easy clogging, low efficiency, and excessive manual intervention in the traditional edible fungi grading and screening process, but also reduces energy consumption and costs, improves production efficiency and product quality through intelligent and automated design, bringing significant technological progress and economic benefits to the edible fungi processing industry.
