Description

Technical Field

[0001] The present invention relates to the technical field of oyster mushroom residue fertilizer fermentation, in particular to a modular oyster mushroom residue fertilizer fermentation device and a fermentation method. Background Art

[0002] Mushroom residue is rich in nutrients such as protein, trace elements, vitamins, etc. The organic matter content can reach 35%-70%, and the nitrogen, phosphorus and potassium nutrients can reach about 5%. It is a good raw material for organic fertilizer. It can be made into high-quality organic fertilizer by decomposing some macromolecular substances in the mushroom residue through high-temperature fermentation.

[0003] Existing organic fertilizers made from oyster mushroom residue require a fermentation device during fermentation. This fermentation device primarily includes a housing with a cavity and a stirring mechanism. During use, the residue and other raw materials are placed into the cavity. The stirring mechanism is used to stir the raw materials at a certain frequency during the fermentation process, causing them to swirl and fully come into contact with oxygen, thereby achieving a better fermentation effect. However, the stirring mechanism of existing devices often includes a rotating shaft and stirring blades fixed to each other by welding. This makes it difficult to remove the multiple stirring blades when they need to be cleaned or replaced, or requires the entire rotating shaft and multiple blades to be removed from the housing at the same time, which is quite cumbersome. Summary of the Invention

[0004] The present invention provides a modularized oyster mushroom residue fertilizer fermentation device and a fermentation method, which can overcome certain defects of the prior art.

[0008] The stirring module comprises a plurality of blade assemblies which are spaced apart along the length direction of the rotating shaft and are detachably connected.

[0009] Through the modular setting of the present invention, the fermentation module, the driving module and the stirring module can be disassembled. When cleaning or replacement is needed, the modules can be easily disassembled for cleaning and replacement. The disassembled modules are easy to transport and can be assembled as needed.

[0010] Preferably, the blade assembly includes a first stirring blade and a second stirring blade symmetrically arranged on both sides of the rotating shaft; the first stirring blade and the second stirring blade are connected to a hinge seat on the same side; a hinge plate is fixed to the hinge seat; the two hinge plates are arranged at intervals and hinged to each other; a clamping block is fixed to the surface of the rotating shaft; the facing sides of the two hinge plates jointly form a clamping slot for cooperating with the clamping block; the first stirring blade and the second stirring blade are each provided with an insert plate on the side away from the hinge seat; a locking member for simultaneously fixing the two insert plates is provided at the rotating shaft.

[0011] In the present invention, by arranging the hinged plate, the card block, the plug plate and the locking piece, the first stirring blade and the second stirring blade can be hinged to each other to achieve folding. When installing them on the rotating shaft, it is only necessary to flip the first stirring blade and the second stirring blade, engage the hinged plate with the card block, and connect the plug plate with the locking piece, so that the first stirring blade and the second stirring blade cannot be folded, moved axially along the rotating shaft, or perform any other activities, and are fixed to the rotating shaft.

[0012] Preferably, the locking member includes a fixing seat fixed on the surface of the rotating shaft; slots for the inserting plate to be inserted into are provided on both sides of the fixing seat; a threaded hole is provided at one end of the fixing seat and is arranged along the radial direction of the rotating shaft and located between the two slots; a bolt is threadedly fitted at the threaded hole of the fixing seat; a connecting plate is provided at one end of the fixing seat and is pressed between the bolt and the fixing seat; an inserting block is provided at the connecting plate; a second socket is provided at one end of the fixing seat and is connected to the slot and is used for the inserting block to be inserted into; and a first socket is provided at the inserting plate for the inserting block to be inserted into.

[0013] In the present invention, by arranging the bolt and the block in the locking member, the block can be engaged with the first socket of the plug plate when the bolt is rotated, and fixation can be achieved by rotating only one bolt; or when rotating in the other direction, the connecting plate is not pressed against the fixing seat, so that the block can be separated from the first socket due to gravity, and the plug plate can be separated from the fixing seat. At this time, the first stirring blade and the second stirring blade can be folded, so that the hinged plate and the block are released, so that the blade assembly can be disassembled by rotating only one bolt, which is very convenient.

[0014] Preferably, the hinge plate and the insert plate have arc-shaped surfaces close to the rotating shaft and fit in with the surface of the rotating shaft; and the end of the clamping block away from the rotating shaft is provided with a chamfer close to the hinge seat.

[0015] In the present invention, the arc-shaped arrangement of the hinged plate and the insert plate enables the hinged plate, the insert plate, the first stirring blade, and the second stirring blade to be able to embrace the rotating shaft, thereby increasing the contact surface and ensuring the fixing strength; and the chamfered arrangement of the clamping block ensures that the first stirring blade and the second stirring blade will not be restricted by the clamping block when they are folded toward each other during installation or disassembly.

[0016] Preferably, the driving module includes a transmission module; the transmission module includes a rotating rod that rotates vertically and is engaged on one side of the box; the rotating shaft passes through both sides of the box and remains parallel to the rotating rod; the rotating shaft is coaxially connected to the first driven gear at one end close to the rotating rod; the rotating rod is coaxially connected to the first driving gear that meshes with the first driven gear; the number of teeth of the first driving gear is less than the number of teeth of the first driven gear; and a turning handle is provided at the end of the rotating rod.

[0017] In the present invention, through the setting of the transmission module, when the handle is turned, the first driving gear can be driven to rotate, and then the first driven gear can be driven to rotate, so that the rotating shaft rotates, and the material in the fermentation chamber is turned through multiple blade assemblies; and the number of teeth of the first driving gear is smaller than the number of teeth of the first driven gear, so that the torque of the rotating shaft can be increased when the handle is turned, making it easier to turn the material.

[0018] Preferably, a first air duct extending axially inward is provided at one end of the rotating shaft near the rotating rod; a plurality of air outlets communicating with the first air duct are provided on the surface of the rotating shaft; a second air duct communicating with the air outlet is provided at one end of the first stirring blade and the second stirring blade near the rotating shaft; and a slot communicating with the second air duct is provided at both the first stirring blade and the second stirring blade.

[0019] In the present invention, by setting the first air duct, the air outlet, the second air duct and the slot, the air outside the box can enter from the end of the rotating shaft, pass through the above-mentioned passages in turn, and enter each blade assembly, so that the oxygen comes into contact with the material at that location, thereby increasing the amount of oxygen contact with the material at each location, improving the turning effect and improving efficiency.

[0020] Preferably, an air supply member is provided at the box body; the air supply member includes an air guide tube fixed at the box body; the air guide tube is conical in shape; the smaller end of the air guide tube is rotatably engaged with the rotating shaft and is connected to the first air duct; a fan blade that rotates in cooperation is provided at the larger end of the air guide tube; a second driving gear is coaxially connected to the rotating rod, and a second driven gear that meshes with the second driving gear is provided at the fan blade; the number of teeth of the second driving gear is greater than the number of teeth of the second driven gear.

[0021] In the present invention, by setting the air supply member, the handle can drive the second driving gear to rotate when it is rotated, and then drive the second driven gear and the fan blades to rotate, so that the air outside the box can quickly enter the first air duct, and then a large amount of oxygen can quickly reach the materials at various positions. In addition, the number of teeth of the second driving gear is greater than the number of teeth of the second driven gear, so when the handle is turned, the fan blades can be driven to rotate more quickly, thereby improving the efficiency of oxygen supply.

[0022] Preferably, the first stirring blade and the second stirring blade are both provided with an anti-blocking component; the anti-blocking component includes an anti-blocking cover which is mounted on the outside of the first stirring blade and the second stirring blade for sealing the slot; a positioning block is fixed to one end of the anti-blocking cover; a positioning groove for the positioning block to extend into is provided at the hinged seat; the positioning block and the hinged seat are connected by fasteners; a filter screen is provided at the anti-blocking cover along the length direction, and the pores of the filter screen are connected to the slot.

[0023] In the present invention, through the setting of the anti-blocking component, the anti-blocking cover can block the notch to prevent the material from entering the notch so that the air outside the box cannot enter. At the same time, the filter of the anti-blocking cover can ensure that the oxygen at the notch can enter the fermentation chamber. When the blade assembly is driven to rotate, the side of the anti-blocking cover away from the rotation direction will not contact the material, and the material will not block the filter on this side, thereby ensuring good anti-blocking and ventilation effects.

[0024] Preferably, a scraper assembly is provided at the anti-blocking assembly; the scraper assembly includes a connecting seat arranged along the length direction of the box body and kept vertically fixed with multiple anti-blocking covers; a mounting plate arranged along the length direction of the connecting seat is provided at the side of the connecting seat away from the anti-blocking cover; a scraper bar that is plugged in and fits along the length direction of the mounting plate is provided at the side of the mounting plate away from the connecting seat; a guide rod is provided at the mounting plate; a limiting cap is provided at the end of the guide rod; a guide hole for the guide rod to pass through is provided at the connecting seat; multiple telescopic rods are provided at the mounting plate; a groove for the telescopic rod to extend into is provided at the connecting seat; a spring is provided in the groove that is pressed against the end of the telescopic rod; the spring is used to enable the scraper bar to maintain contact with the inner wall of the fermentation chamber.

[0025] In the present invention, by setting the scraper assembly, the scraper bar can always contact the inner wall of the fermentation chamber when the rotating shaft rotates, preventing the material close to the inner wall from being stirred by the first stirring blade and the second stirring blade. At the same time, by setting the telescopic rod and the spring, the scraper bar can still maintain contact with the inner wall of the fermentation chamber after wear; therefore, the above structure can not only ensure a good stirring and turning effect of the material, but also when cleaning the fermentation chamber, it is only necessary to pour water to drive the scraper bar to contact and rub with the inner wall of the fermentation chamber, so that the inner wall of the fermentation chamber that is more difficult to reach can be cleaned.

[0026] A method for fermenting oyster mushroom residue fertilizer is realized by any one of the modular fermentation devices for oyster mushroom residue fertilizer described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In this embodiment, the blade assembly 130 includes a first stirring blade 431 and a second stirring blade 432 symmetrically arranged on both sides of the rotating shaft 223; the first stirring blade 431 and the second stirring blade 432 are connected to a hinge seat 436 on the same side; a hinge plate 433 is fixed to the hinge seat 436; the two hinge plates 433 are arranged at intervals and hinged to each other; a clamping block 435 is fixed to the surface of the rotating shaft 223; the facing sides of the two hinge plates 433 jointly form a bayonet 434 for cooperating with the clamping block 435; the first stirring blade 431 and the second stirring blade 432 are both provided with an insert plate 7377 on the side away from the hinge seat 436; a locking member 437 for simultaneously fixing the two insert plates 7377 is provided at the rotating shaft 223.

When installing with the rotating shaft 223, it is only necessary to flip the first stirring blade 431 and the second stirring blade 432, engage the hinged plate 433 with the block 435, and connect the insert plate 7377 with the locking piece 437, so that the first stirring blade 431 and the second stirring blade 432 cannot be folded, moved axially along the rotating shaft 223, or any other activities, and are fixed to the rotating shaft 223.

[0049] In this embodiment, the locking member 437 includes a fixing seat 7370 fixed on the surface of the rotating shaft 223; slots 7372 for the inserting plate 7377 to extend into are provided on both sides of the fixing seat 7370; a threaded hole 7373 is provided at one end of the fixing seat 7370 and is arranged along the radial direction of the rotating shaft 223 and located between the two slots 7372; a bolt 7376 is threadedly engaged with the threaded hole 7373 of the fixing seat 7370; a connecting plate 7374 is provided at one end of the fixing seat 7370 and is tightly pressed between the bolt 7376 and the fixing seat 7370; an inserting block 7375 is provided at the connecting plate 7374; a second socket 7371 is provided at one end of the fixing seat 7370 and is connected to the slot 7372 and is used for the inserting block 7375 to extend into; a first socket 7378 is provided at the inserting plate 7377 for the inserting block 7375 to extend into.

At this time, the first stirring blade 431 and the second stirring blade 432 can be folded, so that the hinge plate 433 and the block 435 are released, so that the blade assembly 130 can be disassembled by rotating only one bolt 7376, which is very convenient.

[0051] In this embodiment, the hinge plate 433 and the inserting plate 7377 are both arc-shaped on one side close to the rotating shaft 223 and fit the surface of the rotating shaft 223 ; the end of the clamping block 435 away from the rotating shaft 223 is provided with a chamfer close to the hinge seat 436 .

[0052] Through the arc-shaped setting of the hinged plate 433 and the insert plate 7377 in this embodiment, the hinged plate 433, the insert plate 7377, the first stirring blade 431, and the second stirring blade 432 can be encircled at the rotating shaft 223, thereby increasing the contact surface to ensure the fixing strength; and the chamfered setting of the block 435 ensures that the first stirring blade 431 and the second stirring blade 432 will not be restricted by the block 435 when they are folded toward each other during installation or disassembly.

[0054] Through the arrangement of the transmission module 140 in this embodiment, when the handle 242 is rotated, the first driving gear 243 can be driven to rotate, thereby driving the first driven gear 244 to rotate, causing the rotating shaft 223 to rotate, and turning the material in the fermentation chamber 111 through the multiple blade assemblies 130; and the number of teeth of the first driving gear 243 is smaller than the number of teeth of the first driven gear 244, so that the torque of the rotating shaft 223 can be increased when the handle 242 is rotated, making it easier to turn the material.

[0055] In this embodiment, a first air duct 521 extending axially inward is provided at one end of the rotating shaft 223 near the rotating rod 241; a plurality of air outlets 722 communicating with the first air duct 521 are provided on the surface of the rotating shaft 223; a second air duct 538 communicating with the air outlet 722 is provided at one end of the first stirring blade 431 and the second stirring blade 432 near the rotating shaft 223; a slot 539 communicating with the second air duct 538 is provided at both the first stirring blade 431 and the second stirring blade 432.

[0056] Through the arrangement of the first air duct 521, the air outlet 722, the second air duct 538 and the slot 539 in this embodiment, the air outside the box 114 can enter from the end of the rotating shaft 223, pass through the above-mentioned passages in turn, and enter each blade assembly 130, so that the oxygen comes into contact with the material at that location, thereby increasing the amount of oxygen in contact with the material at each location, improving the turning effect and improving efficiency.

[0057] In this embodiment, an air supply member 250 is provided at the box body 114; the air supply member 250 includes an air guide tube 253 fixed at the box body 114; the air guide tube 253 is conical in shape; the smaller end of the air guide tube 253 is rotatably engaged with the rotating shaft 223 and is connected to the first air duct 521; a fan blade 254 is provided at the larger end of the air guide tube 253 for rotatable engagement; a second driving gear 251 is coaxially connected to the rotating rod 241, and a second driven gear 252 meshing with the second driving gear 251 is provided at the fan blade 254; the number of teeth of the second driving gear 251 is greater than the number of teeth of the second driven gear 252.

[0058] By setting the air supply member 250 in this embodiment, the turning handle 242 can drive the second driving gear 251 to rotate when it is rotated, and then drive the second driven gear 252 and the fan blades 254 to rotate, so that the air outside the box 114 can quickly enter the first air duct 521, thereby allowing a large amount of oxygen to quickly reach the materials at various positions. In addition, the number of teeth of the second driving gear 251 is greater than the number of teeth of the second driven gear 252. Therefore, when the turning handle 242 is turned, the fan blades 254 can be driven to rotate more quickly, thereby improving the efficiency of oxygen supply.

[0059] In this embodiment, the first stirring blade 431 and the second stirring blade 432 are both provided with an anti-blocking component 360; the anti-blocking component 360 includes an anti-blocking cover 461 which is mounted on the outside of the first stirring blade 431 and the second stirring blade 432 for sealing the slot 539; a positioning block 463 is fixed to one end of the anti-blocking cover 461; a positioning groove 4360 for the positioning block 463 to extend into is provided at the hinge seat 436; the positioning block 463 is connected to the hinge seat 436 by fasteners; a filter screen 462 is provided at the anti-blocking cover 461 along the length direction, and the pores of the filter screen 462 are connected to the slot 539.

At the same time, the filter 462 of the anti-blocking cover 461 can ensure that the oxygen at the slot 539 can enter the fermentation chamber 111. When the blade assembly 130 is driven to rotate, the side of the anti-blocking cover 461 facing away from the rotation direction will not contact the material, and the material will not block the filter 462 on this side, thereby ensuring good anti-blocking and ventilation effects.

[0061] In this embodiment, a scraper assembly 370 is provided at the anti-blocking assembly 360; the scraper assembly 370 includes a connecting seat 1071 arranged along the length direction of the box body 114 and maintained vertically fixed with multiple anti-blocking covers 461; a mounting plate 1072 arranged along the length direction of the connecting seat 1071 is provided on the side of the connecting seat 1071 away from the anti-blocking cover 461; a scraper strip 1073 is provided on the side of the mounting plate 1072 away from the connecting seat 1071 and is plugged into and matched with the mounting plate 1072 along the length direction of the mounting plate 1072; A guide rod 1075 is provided; a limit cap 1076 is provided at the end of the guide rod 1075; a guide hole 1074 for the guide rod 1075 to pass through is provided at the connecting seat 1071; a plurality of telescopic rods 1078 are provided at the mounting plate 1072; a groove 12710 for the telescopic rod 1078 to extend into is provided at the connecting seat 1071; a spring 1277 is provided in the groove 12710 and is pressed against the end of the telescopic rod 1078; the spring 1277 is used to enable the scraper 1073 to maintain contact with the inner wall of the fermentation chamber 111.

[0062] Through the arrangement of the scraper assembly 370 in this embodiment, the scraper bar 1073 can always contact the inner wall of the fermentation chamber 111 when the rotating shaft 223 rotates, preventing the material close to the inner wall from being stirred by the first stirring blade 431 and the second stirring blade 432. At the same time, through the arrangement of the telescopic rod 1078 and the spring 1277, the scraper bar 1073 can still maintain contact with the inner wall of the fermentation chamber 111 after wear; therefore, the above structure can not only ensure a good stirring and turning effect of the material, but also when cleaning the fermentation chamber 111, it is only necessary to pour water to drive the scraper bar 1073 to contact and rub against the inner wall of the fermentation chamber 111, so that the inner wall of the fermentation chamber 111 that is more difficult to reach can be cleaned.
