[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting 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. The blocking and lifting effect of the grid gap slows down the falling speed of the material, avoiding uneven screening or clogging of the screen holes caused by high-speed impact vibration of the screen plate 22. At the same time, the grid plates moving up and down can stir the material that may be accumulated between the feed port and the screen plate, destroying the material arch bridge structure, preventing the blockage problem caused by material accumulation at the feed port, and ensuring smooth material falling;

[0015] 2. Through the shearing mechanism, the vertical movement of the lifting mounting plate drives the shearing base to move vertically. The vertically moving shearing base drives the second gear disc to move vertically through the first gear disc. The second gear disc moves vertically and drives the second gear disc to rotate through the meshing action with the fixed rack. The rotating second gear disc drives the first gear disc to rotate. The rotating first gear disc drives the third gear disc to rotate through the meshing action. The rotating third gear disc drives the reciprocating screw rod to rotate. The rotation of the reciprocating screw rod drives the moving thread ring to move linearly through the thread action. The moving thread ring in linear motion drives the sleeve to move linearly inside the connecting pipe. The linear motion of the casing drives the movable frame to move linearly, the linear motion of the movable frame drives the second lifting plate to move linearly, the linear motion of the second lifting plate drives the second mesh plate to move linearly, and the linear motion of the second mesh plate shears or scrapes the material in the horizontal direction, and cooperates with the vertical motion to form a "cross-cutting" effect to enhance the cutting and crushing of the material. At the same time, the lateral motion promotes the horizontal diffusion of the material 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 double-mesh plate compound motion significantly improves the refinement, efficiency and adaptability of screening compared with the single vertical motion.

[0016] 3. By setting a swing mechanism, the upward moving connecting pipe drives the fourth gear to move upward, and the upward movement of the fourth gear drives the fourth gear to rotate through the meshing action with the intermittent rack, and the rotation of the fourth gear drives the mobile frame to flip around the mobile thread ring through the sleeve, and the rotation of the fourth gear and the flipping movement of the mobile frame can simultaneously drive the first lifting plate and the second lifting plate to flip. When the fourth gear has no teeth, the rebound spring can drive the first lifting plate to move downward for reset. During the vertical movement of the connecting pipe, the first lifting plate and the second lifting plate can continue to flip. When the two grid plates are During synchronous flipping, the actual passing diameter of the sieve holes will change periodically (for example, when the mesh plate is tilted, the horizontal projection size of the sieve holes becomes smaller), which can cut large particles when the sieve holes are open, and block and further crush them when the sieve holes are narrowed. The effective size of the sieve holes can be dynamically adjusted to optimize particle size control. At the same time, the flipping action will drive the material stuck in the sieve holes to vibrate up and down. The periodic flipping will cause the screen surface to form wave-like fluctuations, pushing the material to slide to the lower side. The linear motion of the second mesh plate can evenly disperse the culture material on the top of the screen surface, effectively utilizing the screening effect of the entire screen surface, improving material fluidity and avoiding accumulation.

[0017] 4. Through the joint action of the sliding limit plate and the T-shaped clamping plate, the rotation of the connecting pipe drives the shear base to flip, the flipping movement of the shear base drives the T-shaped clamping plate to flip, and the flipping movement of the 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 disc to flip synchronously through the contact with the top flip arc plate and the joint action of the hydraulic damper, avoiding the problem of teeth jamming between the second gear disc and the fixed rack.

[0035] Since how the screening box 2 realizes screening of the oyster mushroom culture medium is an existing technology, this solution does not describe the specific screening process in detail. This solution is to solve the problem that the material is easily accumulated at the feed inlet during the screening process. The specific operation process is as follows:

[0036] When screening the King Oyster Mushroom culture medium material, the King Oyster Mushroom culture medium material needs to be put into the screening box 2 through the feed hopper 4, and then the King Oyster Mushroom culture medium material is screened by the vibrating sieve plate 22. When the King Oyster Mushroom culture medium material is put into the feed hopper 4, the base material can enter the screening box 2 through the feed hopper 4. Before falling onto the vibrating sieve plate 22, the King Oyster Mushroom culture medium material passes through the first mesh plate 18 and the second mesh plate 19 to slow down the speed at which the King Oyster Mushroom culture medium material falls on the top of the vibrating sieve plate 22, thereby preventing the culture medium material from being concentrated and accumulated on the top of the vibrating sieve plate 22, thereby improving the screening effect of the King Oyster Mushroom culture medium material;

[0037] While screening the culture medium of King Oyster Mushroom, the driving motor 7 is started, the driving motor 7 rotates to drive the rotating disk 8 to rotate, the rotating rotating disk 8 drives the connecting rod 9 to perform circular motion, the circular motion connecting rod 9 drives the lifting seat 10 to move vertically inside the motor mounting seat 6, the vertical motion of the lifting seat 10 drives the lifting connecting plate 12 to move vertically, the vertical motion of the lifting connecting plate 12 drives the lifting mounting plate 14 to move vertically through the lifting sliding block 13, the vertical motion of the lifting mounting plate 14 drives the fixing frame 15 to move vertically, the vertical motion of the fixing frame 15 drives the connecting pipe 16 to move vertically, and the vertical motion of the connecting pipe 16 is rebounded. The mounting plate 34 drives the first lifting plate 17 and the second lifting plate 20 to move vertically. The vertically moving first lifting plate 17 and the second lifting plate 20 drive the first mesh plate 18 and the second mesh plate 19 to move vertically. The vertical movement of the two mesh plates can form a relative movement with the falling material. The blocking and lifting effect of the mesh gaps can slow down the falling speed of the material, avoid uneven screening or clogging of the screen holes caused by high-speed impact vibration of the screen plate 22, and at the same time, the mesh plates moving up and down can stir the material that may be accumulated between the feed port and the screen plate, destroy the material arch bridge structure, prevent the blockage problem caused by material accumulation at the feed port, and ensure smooth material dropping.

[0038] See also Figure 1 and Figure 4 During the specific implementation process, it was found that some of the King Oyster Mushroom culture materials had a certain humidity, which made the King Oyster Mushroom culture materials have a certain viscosity. It was not possible to effectively screen them by simply shaking them. In order to solve the above problem, the following technical improvements were made;

[0039] The shearing mechanism includes a shearing base 23 fixedly connected to the top of the other side of the connecting pipe 16, and one side of the shearing base 23 is rotatably connected to a first toothed disc 24, the other side of the first toothed disc 24 is fixedly connected to a second toothed disc 25, and the outer wall of the second toothed disc 25 is meshedly connected to a fixed rack 26, the inner side of the screening box 2 is respectively fixedly connected to two fixed cross plates 27, the outer side of the first toothed disc 24 is meshedly connected to a third toothed disc 28, and a moving component is provided on one side of the third toothed disc 28, which includes a fixed connection. A reciprocating screw rod 29 is connected to one side of the third gear disc 28, and the outer wall of the reciprocating screw rod 29 is threadedly connected to a movable thread ring 30, and the top of the movable thread ring 30 is fixedly connected to a movable frame 32. A limiting groove matching the movable frame 32 is provided on the top of the connecting tube 16, and the outer wall of the movable frame 32 is slidingly connected to the inner wall of the connecting tube 16. One end of the reciprocating screw rod 29 passes through the interior of the connecting tube 16 and is rotatably connected to the connecting tube 16. The other side of the movable frame 32 is fixedly connected to one side of the second lifting plate 20.

[0040] The vertical movement of the lifting mounting plate 14 drives the shear base 23 to move vertically. The vertically moving shear base 23 drives the second gear disc 25 to move vertically through the first gear disc 24. The second gear disc 25 moves vertically and drives the second gear disc 25 to rotate by meshing with the fixed rack 26. The rotating second gear disc 25 drives the first gear disc 24 to rotate. The rotating first gear disc 24 drives the third gear disc 28 to rotate by meshing. The rotating third gear disc 28 drives the reciprocating screw rod 29 to rotate. The rotation of the reciprocating screw rod 29 drives the moving thread ring 30 to move linearly through the thread action. The linear motion of the moving thread ring 3 0 drives the movable frame 32 to move linearly, the linear movement of the movable frame 32 drives the second lifting plate 20 to move linearly, the linear movement of the second lifting plate 20 drives the second mesh plate 19 to move linearly, the linear movement of the second mesh plate 19 shears or scrapes the material in the horizontal direction, and cooperates with the vertical movement to form a "cross cutting" effect to enhance the cutting and crushing of the material. At the same time, the lateral movement promotes the horizontal diffusion of the material on the screen plate to avoid local accumulation or "biased flow", that is, the material is concentrated on one side, which can promote the uniform distribution of the material. The double-mesh plate compound movement significantly improves the refinement, efficiency and adaptability of screening compared with the single vertical movement.

[0041] See also Figure 5 and Figure 7 During the specific implementation process, it was found that during the screening process of the King Oyster Mushroom culture medium, the first grid plate 18 and the second grid plate 19 were only operating on the grid plate located directly below the feed hopper 4, and most of the grid surface was not effectively utilized. In order to solve the above problem, the following technical improvements were made;

[0042] The swing mechanism includes a fourth gear 31 fixedly connected to the outer wall of the connecting tube 16 and close to the side of the fixed frame 15, and the outer wall of the fourth gear 31 is meshed with an intermittent rack 33, and the inner side of the intermittent rack 33 is fixedly connected to the other side of the two fixed cross plates 27 respectively, and the inner side of the intermittent rack 33 is fixedly connected to multiple groups of teeth meshing with the fourth gear 31, and the multiple groups of teeth are equidistantly distributed on the inner side of the intermittent rack 33. The swing mechanism also includes a rebound mounting plate 34 fixedly connected to one side of the first grid plate 18, and a rebound spring 35 is arranged between the rebound mounting plate 34 and the vibrating screen plate 22.

[0043] The upward moving connecting pipe 16 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 movable frame 32 to flip around the movable thread ring 30 through the connecting pipe 16. The rotation of the fourth gear 31 and the flipping movement of the movable 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, the rebound spring 35 can drive the first lifting plate 17 to move downward for reset. During the vertical movement of the connecting pipe 16, the first lifting plate 17 and the second lifting plate 20 can be kept in the vertical direction. The flipping movement continues. When the two mesh plates flip synchronously, the actual passing diameter of the sieve hole will change periodically (for example, when the mesh plate is tilted, the horizontal projection size of the sieve hole becomes smaller), which can cut large particles when the sieve hole is open and block and further crush them when the sieve hole is reduced. The effective size of the sieve hole can be dynamically adjusted to optimize the particle size control. At the same time, the flipping action will drive the material stuck in the sieve hole to vibrate up and down. The periodic flipping will cause the screen surface to form wave-like fluctuations, pushing the material to slide to the lower side, and the linear motion of the second mesh plate 19 can make the culture material on the top evenly dispersed on the top of the screen surface, effectively utilizing the screening effect of the entire screen surface, improving material fluidity, and avoiding accumulation.

[0044] See also Figure 8 and Figure 13 During the specific implementation process, it was found that when the connecting tube 16 drives the movable frame 32 to rotate around the movable threaded ring 30, the movable threaded ring 30 would drive the reciprocating screw 29 to rotate, and the meshing effect between the second gear plate 25 and the fixed rack 26 would cause the teeth to get stuck. In order to solve the above problem, the following technical improvements were made;

[0045] The shearing mechanism also includes a sliding limit plate 37 fixedly connected to one side of the fixed rack 26, a T-shaped card plate 36 is slidably connected to the interior of the sliding limit plate 37, and a hydraulic damper 39 is provided between the bottom of the T-shaped card plate 36 and the sliding limit plate 37. The T-shaped card plate 36 is fixedly connected to one side of the shear base 23, the bottom of the fixed cross plate 27 is fixedly connected to a flip arc plate 38, and the top of one side of the fixed rack 26 is fixedly connected to a flip sliding block 40. The inner side of the flip arc plate 38 is provided with a T-shaped groove that matches the flip sliding block 40, and the outer side of the flip sliding block 40 is slidably connected to the inner side of the flip arc plate 38;

[0046] The rotation of the connecting pipe 16 drives the shear base 23 to flip, and the flipping movement of the shear base 23 drives the T-shaped clamping plate 36 to flip, and the flipping movement of the T-shaped clamping plate 36 drives the sliding limit plate 37 to flip, and the flipping movement of the sliding limit plate 37 drives the fixed rack 26 and the second gear disc 25 to flip synchronously through the abutment with the top flip arc plate 38 and the combined action of the hydraulic damper 39, thereby avoiding the problem of teeth being stuck between the second gear disc 25 and the fixed rack 26.

[0047] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the field of Pleurotus eryngii cultivation technology can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, and the same shall be covered by the scope of protection of the present invention.
