[0003] To ensure the uniform mixing of the culture medium materials for Pleurotus eryngii, it is necessary to screen the raw materials of the culture medium materials to maintain the consistency of the culture medium materials. During the screening process, since screening takes a certain amount of time, raw materials are prone to accumulate at the position of the sieve plate where the material is fed, thus blocking the screening port and affecting the screening effect of the Pleurotus eryngii culture medium materials.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By providing the first grid plate, the second grid plate and the lifting mechanism, the vertically moving first lifting plate and the second lifting plate drive the first grid plate and the second grid plate to move vertically. The vertical movement of the two grid plates can form a relative movement with the falling material. Through the blocking and lifting effects of the grid gaps, the falling speed of the material is slowed down, avoiding uneven screening or screen hole blockage caused by high-speed impact on the vibrating screen plate 22. At the same time, the vertically moving grid plates can agitate the material that may accumulate between the feed inlet and the screen plate, destroy the material arch structure, prevent the blockage problem caused by material accumulation at the feed inlet, and ensure smooth material falling. 2. By providing the shearing mechanism, the vertically moving lifting mounting plate drives the shearing base to move vertically. The vertically moving shearing base drives the second gear disk to move vertically through the first gear disk. The vertically moving second gear disk drives the second gear disk to rotate through the meshing action with the fixed rack. The rotating second gear disk drives the first gear disk to rotate. The rotating first gear disk drives the third gear disk to rotate through the meshing action. The rotating third gear disk drives the reciprocating lead screw to rotate. The reciprocating lead screw rotates to drive the moving threaded ring to move linearly through the thread action. The linearly moving moving threaded ring drives the sleeve to move linearly inside the connecting pipe. The linearly moving sleeve drives the moving frame to move linearly. The linearly moving moving frame drives the second lifting plate to move linearly. The linearly moving second lifting plate drives the second grid plate to move linearly. The linearly moving second grid plate shears or scrapes the material in the horizontal direction, and forms a "cross-cutting" effect in cooperation with the vertical movement to strengthen the cutting and crushing of the material. At the same time, the horizontal movement pushes the material to spread horizontally on the screen plate, avoiding local accumulation or "biased flow", that is, the material concentrates on one side, which can promote the uniform distribution of the material. The composite movement of the double grid plates significantly improves the refinement, efficiency and adaptability of screening compared with the single vertical movement. 3. By setting up a swinging mechanism, the connecting pipe moving upward drives the fourth gear upward. The upward movement of the fourth gear drives the fourth gear to rotate through the meshing action with the intermittent rack. The rotation of the fourth gear drives the moving frame to flip around the moving threaded ring through the sleeve. The rotation of the fourth gear and the flipping movement of the moving frame can drive the first lifting plate and the second lifting plate to flip simultaneously. When the fourth gear has no teeth, it can drive the first lifting plate to move downward for reset through the return spring. During the vertical movement of the connecting pipe, the first lifting plate and the second lifting plate can continuously flip. When the two grid plates flip synchronously, the actual passing diameter of the sieve holes will change periodically (for example: when the grid plate is tilted, the horizontal projection size of the sieve holes becomes smaller). This can cut large particles when the sieve holes are open, block them and further crush them when the sieve holes shrink. It can dynamically adjust the effective size of the sieve holes, optimize the particle size control. At the same time, the flipping action will drive the materials stuck in the sieve holes to vibrate up and down. The periodic flipping will cause the sieve surface to form a wavy undulation, pushing the materials to slide towards the lower side. And through the linear movement of the second grid plate, the culture medium at the top can be evenly dispersed on the top of the sieve surface, effectively utilizing the screening effect of the overall sieve surface, improving the fluidity of the materials and avoiding accumulation; 4. Through the combined action of the sliding limit plate and the T-shaped clamping plate set, the rotation of the connecting pipe drives the shear base to flip. The flipping shear base drives the T-shaped clamping plate to flip. The flipping T-shaped clamping plate drives the sliding limit plate to flip. The flipping movement of the sliding limit plate drives the fixed rack and the second gear disk to flip synchronously through the abutment with the flipping arc plate at the top and the combined action of the hydraulic damper, avoiding the problem of tooth jamming between the second gear disk and the fixed rack.

A connecting rod 9 is fixedly connected to the other side of the rotating disk 8 away from the central axis. The lifting mechanism further includes a lifting seat 10 sleeved on the outer wall of the connecting rod 9. A connecting groove 11 matching the connecting rod 9 is opened inside the lifting seat 10. The lifting seat 10 is slidably connected to the inside of the motor mounting seat 6. The bottom of the lifting seat 10 is fixedly connected to a lifting connecting plate 12. A lifting sliding block 13 is fixedly connected to the bottom of the lifting connecting plate 12. A lifting mounting plate 14 is fixedly connected to the bottom of the lifting sliding block 13.

A second lifting plate 20 is slidably connected to the top of the first lifting plate 17. A second grid plate 19 is fixedly connected to one side of the second lifting plate 20.

[0019] Since how the screening box 2 realizes the screening of Pleurotus eryngii culture medium is prior art, the specific screening process is not described in detail in this solution. This solution aims to solve the problem of material accumulation at the feed inlet during the screening process. The specific operation process is as follows: When screening the Pleurotus eryngii culture medium, the Pleurotus eryngii culture medium needs to be put into the screening box 2 through the feed hopper 4, and then the Pleurotus eryngii culture medium is screened by the vibrating sieve plate 22. When the Pleurotus eryngii culture medium is put into the inside of the feed hopper 4, the base material can enter the inside of the screening box 2 through the feed hopper 4. Before the Pleurotus eryngii culture medium falls onto the vibrating sieve plate 22, the first grid plate 18 and the second grid plate 19 can slow down the speed of the Pleurotus eryngii culture medium falling onto the top of the vibrating sieve plate 22, and can avoid the concentrated accumulation of the culture medium on the top of the vibrating sieve plate 22, thereby improving the screening effect of the Pleurotus eryngii culture medium; While screening the Pleurotus eryngii culture medium, start the drive motor 7. The rotation of the drive motor 7 drives the rotating disk 8 to rotate. The rotating rotating disk 8 drives the connecting rod 9 to perform a circular motion. The connecting rod 9 performing a circular motion drives the lifting seat 10 to move vertically inside the motor mounting seat 6. The vertical movement of the lifting seat 10 drives the lifting connecting plate 12 to move vertically. The vertical movement of the lifting connecting plate 12 drives the lifting mounting plate 14 to move vertically through the lifting sliding block 13. The vertically moving lifting mounting plate 14 drives the fixing frame 15 to move vertically. The vertical movement of the fixing frame 15 drives the connecting pipe 16 to move vertically. The vertically moving connecting pipe 16 drives the first lifting plate 17 and the second lifting plate 20 to move vertically through the resilient mounting plate 34. The vertically moving first lifting plate 17 and second lifting plate 20 drive the first grid plate 18 and the second grid plate 19 to move vertically. The vertical movement of the two grid plates can form a relative movement with the falling material. Through the blocking and lifting effects of the grid gaps, the falling speed of the material is slowed down, avoiding uneven screening or screen hole blockage caused by high-speed impact on the vibrating screen plate 22. At the same time, the vertically moving grid plates can agitate the material that may accumulate between the feed inlet and the screen plate, destroying the arch structure of the material and preventing the blockage problem caused by material accumulation at the feed inlet, ensuring smooth material falling.

[0020] Please refer to Figure 1 and Figure 4 , it was found in the specific implementation process that some Pleurotus eryngii culture media have a certain humidity, making the Pleurotus eryngii culture media have a certain viscosity, and effective screening cannot be carried out only through simple vibration. To solve the above problems, the following technical improvements have been made; The shearing mechanism includes a shearing base 23 fixedly connected to the top of the other side of the connecting pipe 16. One side of the shearing base 23 is rotatably connected to a first gear disk 24. The other side of the first gear disk 24 is fixedly connected to a second gear disk 25. The outer wall of the second gear disk 25 is meshed with a fixed rack 26. Two fixed cross plates 27 are respectively fixedly connected to the inner side of the screening box 2. The outer side of the first gear disk 24 is meshed with a third gear disk 28. And a moving component is arranged on one side of the third gear disk 28. The moving component includes a reciprocating lead screw 29 fixedly connected to one side of the third gear disk 28. The outer wall of the reciprocating lead screw 29 is threadedly connected with a moving thread ring 30. The top of the moving thread ring 30 is fixedly connected to a moving frame 32. A limiting groove matching with the moving frame 32 is opened at the top of the connecting pipe 16. And the outer wall of the moving frame 32 is slidably connected with the inner wall of the connecting pipe 16. One end of the reciprocating lead screw 29 penetrates into the connecting pipe 16 and is rotatably connected with the connecting pipe 16. The other side of the moving frame 32 is fixedly connected to one side of the second lifting plate 20.

[0021] The vertical movement of the lifting mounting plate 14 drives the vertical movement of the shearing base 23. The vertically moving shearing base 23 drives the vertical movement of the second gear disk 25 through the first gear disk 24. The vertical movement of the second gear disk 25 drives the second gear disk 25 to rotate through the meshing action with the fixed rack 26. The rotating second gear disk 25 drives the first gear disk 24 to rotate. The rotating first gear disk 24 drives the third gear disk 28 to rotate through the meshing action. The rotating third gear disk 28 drives the reciprocating lead screw 29 to rotate. The rotation of the reciprocating lead screw 29 drives the moving threaded ring 30 to move linearly through the thread action. The linearly moving moving threaded ring 30 drives the moving frame 32 to move linearly. The linear movement of the moving frame 32 drives the second lifting plate 20 to move linearly. The linearly moving second lifting plate 20 drives the second grid plate 19 to move linearly. The linearly moving second grid plate 19 shears or scrapes the material in the horizontal direction. Cooperating with the vertical movement to form a "cross-cutting" effect can strengthen the cutting and crushing of the material. At the same time, the horizontal movement pushes the material to spread horizontally on the sieve plate, avoiding local accumulation or "biased flow", that is, the material concentrates on one side, which can promote the uniform distribution of the material. The composite movement of the double grid plates significantly improves the refinement, efficiency and adaptability of screening compared with the single vertical movement.

[0022] Please refer to Figure 5 and Figure 7 In the specific implementation process, it is found that during the screening process of the Pleurotus eryngii culture medium, only the grid plate directly below the feed hopper 4 of the first grid plate 18 and the second grid plate 19 is operating, and most of the grid surfaces are not effectively utilized. To solve the above problems, the following technical improvements are made; The swing mechanism includes a fourth gear 31 fixedly connected to the outer wall of the connecting pipe 16 and close to one side of the fixed frame 15. The outer wall of the fourth gear 31 is meshed with an intermittent rack 33. The inner sides of the intermittent rack 33 are respectively fixedly connected to the other sides of two fixed cross plates 27. The inner side of the intermittent rack 33 is fixedly connected with multiple sets of teeth meshing with the fourth gear 31, and the multiple sets of teeth are equidistantly distributed on the inner side of the intermittent rack 33. The swing mechanism further includes a resilient mounting plate 34 fixedly connected to one side of the first grid plate 18, and a resilient spring 35 is arranged between the resilient mounting plate 34 and the vibrating sieve plate 22.

[0023] The connecting pipe 16 moving upward drives the fourth gear 31 to move upward. The upward movement of the fourth gear 31 drives the fourth gear 31 to rotate through the meshing action with the intermittent rack 33. The rotation of the fourth gear 31 drives the moving frame 32 to flip around the moving thread ring 30 through the connecting pipe 16. The rotation of the fourth gear 31 and the flipping movement of the moving frame 32 can simultaneously drive the first lifting plate 17 and the second lifting plate 20 to flip. When the fourth gear 31 has no teeth, it can drive the first lifting plate 17 to move downward for reset through the return spring 35. During the vertical movement of the connecting pipe 16, the first lifting plate 17 and the second lifting plate 20 can continue to flip. When the two grid plates flip synchronously, the actual passing diameter of the sieve holes will change periodically (for example: when the grid plate is tilted, the horizontal projection size of the sieve holes becomes smaller), which can cut large particles when the sieve holes are open, block them when the sieve holes shrink and further crush them, dynamically adjust the effective size of the sieve holes, optimize the particle size control. At the same time, the flipping action will drive the materials stuck in the sieve holes to vibrate up and down. The periodic flipping will cause the sieve surface to form a wavy undulation, pushing the materials to slide to the lower side. And through the linear movement of the second grid plate 19, the culture medium at the top can be evenly dispersed on the top of the sieve surface, effectively utilizing the screening effect of the overall sieve surface, improving the fluidity of the materials and avoiding accumulation.

[0024] Please refer to Figure 8 and Figure 13 In the specific implementation process, it is found that when the connecting pipe 16 drives the moving frame 32 to flip around the moving thread ring 30, the moving thread ring 30 will drive the reciprocating lead screw 29 to rotate, and there is a problem of tooth jamming in the meshing action between the second gear disk 25 and the fixed rack 26. To solve the above problems, the following technical improvements are made; The shearing mechanism further includes a sliding limit plate 37 fixedly connected to one side of the fixed rack 26. A T-shaped clamping plate 36 is slidably connected inside the sliding limit plate 37, and a hydraulic damper 39 is provided between the bottom of the T-shaped clamping plate 36 and the sliding limit plate 37. The T-shaped clamping plate 36 is fixedly connected to one side of the shearing base 23. A flipping arc plate 38 is fixedly connected to the bottom of the fixed cross plate 27. A flipping sliding block 40 is fixedly connected to the top of one side of the fixed rack 26. A T-shaped sliding groove matching the flipping sliding block 40 is opened inside the flipping arc plate 38, and the outside of the flipping sliding block 40 is slidably connected to the inside of the flipping arc plate 38; The rotation of the connecting pipe 16 drives the shearing base 23 to flip. The flipping shearing base 23 drives the T-shaped clamping plate 36 to flip. The flipping T-shaped clamping plate 36 drives the sliding limit plate 37 to flip. The flipping movement of the sliding limit plate 37 drives the fixed rack 26 and the second gear disk 25 to flip synchronously through the abutment with the flipping arc plate 38 at the top and the combined action of the hydraulic damper 39, avoiding the tooth jamming problem between the second gear disk 25 and the fixed rack 26.

Any person skilled in the art of Pleurotus eryngii cultivation who, within the technical scope disclosed by the present invention, makes equivalent substitutions or changes according to the technical solution and inventive concept of the present invention shall be covered by the protection scope of the present invention.
