The device includes a cleaning mechanism, the top of which is fixedly connected to the bottom of a water spraying mechanism. The inner wall of the cleaning mechanism is movably connected to the outer wall of an impurity collection mechanism. This automated device uses a grading conveyor belt to transport shiitake mushrooms with stems inserted into the stem openings, where stem trimming is performed by a stem trimmer.

[0016] This invention provides an automated device for cleaning, stem trimming, drying, and grading shiitake mushrooms. Compared with existing technologies, it has the following advantages: The cleaning mechanism places shiitake mushrooms above a wire mesh conveyor belt. The first drive motor is activated to move the conveyor belt, and a water pump is turned on to allow water to flow through a connecting pipe into a fixed water pipe. Simultaneously, water is sprayed from the bottom of the nozzles to clean the mushrooms. The cleaned mushrooms are then transported by the wire mesh conveyor belt to a grading conveyor belt. Mushrooms with stems inserted are then trimmed by a stem-cutting blade holder. A third drive motor is activated to move the conveyor belt, transporting the mushrooms to a drying rack below. A fourth drive motor is activated to rotate a fan, generating airflow. A heating wire is activated to generate heat, which is then blown onto the nozzles and heated by the heating wire. This heated airflow then dries the mushrooms. The coordinated use of the cleaning rack, grading rack, and fixed rack eliminates the need for separate batches of cleaning, stem trimming, drying, and grading equipment during mushroom processing, increasing processing efficiency.

[0017] The water spray mechanism and the brushes above the wire mesh conveyor belt clean the mud and impurities blocked on the top of the filter plate. As the wire mesh conveyor belt transports the mud and impurities, they move towards the first collection rack and are collected there. When it is necessary to clean the mud and impurities inside the first collection rack, the upward pulling block moves the fixed rod, which in turn moves the positioning slider upward, which in turn moves the first collection rack upward, thus removing it. This facilitates the cleaning and collection of the mud and impurities by the staff, reduces the impact of mud on the water flow, and minimizes the impact of mud on the cleaning effect.

[0018] The impurity collection mechanism and the outer wall of the wire mesh conveyor belt compress the top of the extrusion block. This compression compresses the extrusion block and its compression spring, causing the extension rod to move downwards. The downward movement of the extension rod compresses the top of the pressure rod, which in turn compresses the pressure rod. This pressure rod, through a fixed plate, causes the shear handle frame to move downwards. The downward movement of the shear handle frame causes the moving block to move downwards along the outer wall of the limit rod, simultaneously compressing the vibration spring. When the outer wall of the wire mesh conveyor belt is no longer in contact with the top of the extrusion block, the compression spring resets the extension rod, preventing it from contacting the pressure rod. The reset of the vibration spring then causes the moving block to move upwards. The continuous transmission of the wire mesh conveyor belt causes the shear handle frame to reciprocate up and down, thereby driving... The grading conveyor belt generates vibration, causing the shiitake mushrooms to bounce on its outer wall. Unqualified small shiitake mushrooms fall through the stem openings inside the conveyor belt into the second collection rack, while the stems of qualified shiitake mushrooms are inserted into the stem openings. The second drive motor is activated, driving the grading conveyor belt to transport the mushrooms. The mushrooms with stems inserted into the stem openings are then cut by a stem-cutting blade. Mushrooms with stems not inserted are blocked by a baffle plate until the stems are inserted. The cut stems fall into the second collection rack, and the mushrooms then fall onto the top of the conveyor belt. This convenient device positions the shiitake mushrooms, eliminating the need for manual positioning and increasing the efficiency of shiitake mushroom processing. Attached Figure Description

[0033] The method of use and advantages of this invention: The automated equipment for cleaning, stem trimming, drying and grading shiitake mushrooms operates as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, shiitake mushrooms are placed above the wire mesh conveyor belt 103. The first drive motor 102 is turned on to drive the wire mesh conveyor belt 103 for transmission. The water pump 204 is turned on so that water flows through the connecting pipe 203 into the fixed water pipe 201. At the same time, water is sprayed out from the bottom of the nozzle 202 to wash the shiitake mushrooms. The rinsed water flows through the filter plate 104 and re-enters the washing rack 101. While the wire mesh conveyor belt 103 is transmitting, the brush set above the wire mesh conveyor belt 103 cleans the dirt and impurities blocked on the top of the filter plate 104. As the wire mesh conveyor belt 103 is transmitting, the dirt and impurities move towards the collection rack 302, where they are collected. 02. When it is necessary to clean the soil and impurities inside the collection rack 302, pull the upward pulling block 304 to move the fixed rod 303. The movement of the fixed rod 303 moves the positioning slider 301 upward, which in turn moves the collection rack 302 upward, thus removing the collection rack 302. The cleaned mushrooms are then transported to the top of the grading conveyor belt 705 via the wire mesh conveyor belt 103. During the transmission operation of the wire mesh conveyor belt 103, the outer wall of the wire mesh conveyor belt 103 presses against the top of the extrusion block 402. The extrusion block 402 is pressed against the extrusion spring 401, which in turn moves the extension rod 403 downward. The downward movement of the extension rod 403 presses against the extrusion spring 401. The top of the lever 703 is compressed, and the compression of the lever 703 causes the shear handle frame 701 to move downward through the fixing plate 702. The downward movement of the shear handle frame 701 causes the moving block 602 to move downward along the outer wall of the limiting rod 601, while simultaneously compressing the vibration spring 603. When the outer wall of the wire mesh conveyor belt 103 is no longer in contact with the top of the compression block 402, the return of the compression spring 401 causes the extension rod 403 to return to its original position, preventing the extension rod 403 from contacting the lever 703. The return of the vibration spring 603 then causes the moving block 602 to move upward. Through the continuous transmission operation of the wire mesh conveyor belt 103, the shear handle frame 701 moves up and down reciprocally, thereby causing the grading conveyor belt 705 to generate a vibration force. The vibration at 05 causes the shiitake mushrooms to bounce on the outer wall of the grading conveyor belt 705. Unqualified small shiitake mushrooms fall through the stem openings inside the grading conveyor belt 705 into the collection rack 503. Simultaneously, the stems of qualified shiitake mushrooms are inserted into the stem openings. The second drive motor 704 is activated, driving the grading conveyor belt 705 for transport. Through the transport of the grading conveyor belt 705, shiitake mushrooms with stems inserted into the stem openings are trimmed by the stem-cutting blade holder 706. Shiitake mushrooms with stems not inserted into the stem openings are blocked by the baffle plate 502. The trimmed stems fall into the collection rack 503, and the trimmed shiitake mushrooms fall above the conveyor belt 803. The third drive motor 802 is activated, driving the conveyor belt 803 for transport.The mushrooms are transferred to the bottom of the drying rack 901. The fourth drive motor 902 is activated, driving the fan 903 to rotate, generating airflow. The heating wire 905 is then activated, generating heat. The airflow blown onto the nozzle 904 is heated by the heating wire 905, and the heated air is then blown onto the mushrooms to dry them.
