One end of the rotating shaft 7 on one side is rotatably installed on the inner wall of the circular groove, and one end of the rotating shaft 7 on the other side is rotatably installed on the inner wall of the installation opening. A torsion spring 8 is provided on the outer sleeve of the rotating shaft 7 located in the circular groove, and the two ends of the torsion spring 8 are respectively fixedly connected to the inner wall of the circular groove and the rotating shaft 7. A cross bar 9 is provided in the installation opening and below the grid 5. The cross bar 9 is in contact with one side of the bottom of the grid 5. A driving component for driving the intermittent forward rotation is provided outside the rotating shaft 7 away from the circular groove. A vent 11 is provided at the bottom of the bottom plate 10, and a closing component for closing the vent 11 is provided at the bottom of the bottom plate 10. A through opening 15 is provided on the inner wall of one side of the installation opening close to the cylinder core 2.

[0018] When in use, remove the cover plate 32, take out the cylinder core 2, cancel the connection of the connecting assembly to the cylinder core 2, add lemon peel or orange peel into the cylinder core 2 as a deodorizing material, the cylinder core 2 is a net cylinder, then pull the column 4 with the ring plate 3 to move outside the tank body 1, turn the bolt 33 to separate it from the net frame 5, remove the net plate 6, put the salted fish into the net frame 5, the fish is fire-cooked fish, and the salt concentration of the pickled fish is: 3% - 8%, after putting it in, reset the mesh plate 6, connect the mesh plate 6 to the grid frame 5 by bolts 33, then reset the ring plate 3 so that it is located in the tank body 1, reset the cylinder core 2 and the cover plate 32, at this time the tank body 1 is in a closed environment, and then the fish is pickled. During the pickling, the microorganisms ferment on its surface. After the pickling is completed, cancel the sealing of the vent 11 by the sealing component, lift the cover plate 32, and then make a gap between the cover plate 32 and the top of the tank body 1. At this time, the outside wind enters the tank body 1 through the vent 11, and the fish is air-dried with the smell of the deodorizing material emitted by the cylinder core 2. During the pickling, the fish will release water after being smeared with salt, and the salt water will drip on the bottom of the grid frame 5. After the pickling process, crystals are formed, which will block the bottom mesh of the grid frame 5 and affect the outside wind In order to increase the drying speed, the driving assembly drives the shaft 7 to rotate forward, so that the connected net frame 5 rotates accordingly. When the shaft 7 rotates, the torsion spring 8 is twisted to torsionally deform it. Then the driving assembly cancels the drive to the shaft 7. The torsion spring 8 is reset, and the shaft 7 and the net frame 5 are quickly reset, so that the collision between the net frame 5 and the cross bar 9 stops instantly, generating vibration, thereby shaking off the salt crystals blocked in the mesh holes at the bottom of the net frame 5, so that the mesh holes at the bottom of the net frame 5 are cleaned, and the ventilation effect at the bottom of the net frame 5 is ensured. Subsequently, as the driving assembly works, the net frame 5 can be continuously swung to throw out the moisture in the fish and accelerate the drying effect. When the shaft 7 rotates forward, the net frame 5 rotates accordingly and can fully contact with the wind mixed with the deodorizing material, thereby improving the deodorizing effect.

[0019] like Figure 2 As shown, the connecting assembly includes a connecting frame 27, the top of which is rotatably mounted on the middle of the bottom end of the cover plate 32, the outside of the connecting frame 27 extends to the inside of the cylinder core 2, and the connecting frame 27 and the cylinder core 2 are threadedly connected by screws 28.

[0020] When the cover plate 32 is removed, it takes with it the connecting frame 27, the screw 28, and the tube core 2. The screw 28 is reversed to separate it from the tube core 2, so that the tube core 2 is separated from the connecting frame 27, and the deodorizing material is added into the tube core 2. Then, the screw 28 is turned forward to reset it and connect the tube core 2 to the connecting frame 27, thereby completing the installation of the tube core 2.

[0021] like Figure 3 and Figure 5As shown, the drive assembly includes a first bevel gear 12 fixedly connected to one end of the rotating shaft 7 away from the circular groove, a mounting plate 13 corresponding to the first bevel gear 12 is fixedly installed on the top of the ring plate 3, and a second bevel gear 14 matching the first bevel gear 12 is rotatably installed on the bottom of the mounting plate 13. The second bevel gear 14 and the outer sides of the cylinder core 2 are both provided with matching teeth 16, and the surface of the teeth 16 located on the cylinder core 2 is provided with a toothless section, and a motor 26 is fixedly installed on the top of the cover plate 32, and the output shaft of the motor 26 is fixedly connected to the top of the connecting frame 27.

[0022] Start the motor 26 so that its output shaft carries the connecting frame 27, the screw 28, and the cylinder core 2. The cylinder core 2 cooperates with the teeth 16 to rotate with the second bevel gear 14, thereby cooperating with the first bevel gear 12 to rotate with the rotating shaft 7 and the grid frame 5. As the rotating shaft 7 rotates, the torsion spring 8 is twisted to cause it to twist and deform. Then, the toothless section on the cylinder core 2 moves to the second bevel gear 14. At this time, the torsion spring 8 releases its force to quickly reset the rotating shaft 7 and the grid frame 5, which is contrary to the above principle, so that the second bevel gear 14 is reset. Then, the teeth 16 on the second bevel gear 14 mesh with the teeth 16 on the cylinder core 2 again, and then separate, so that the grid frame 5 can be continuously swung.

[0023] like Figures 6 to 8 As shown, a ring opening 17 is provided on the inner wall of one side of the installation opening close to the barrel core 2, and the ring opening 17 is consistent with the center of the rotating shaft 7. The bottom of one side of the ring opening 17 is closed, and one end of the cross bar 9 extends into the ring opening 17 and conflicts with the bottom wall of the closed part of the ring opening 17. A cavity is provided inside the cross bar 9, and a blowing port 20 is provided on the outer side of the cross bar 9. The blowing port 20 is opened facing the bottom of the grid 5. An injection assembly for injecting hot air into the interior is provided on the outside of the cross bar 9. An arc strip 18 is fixedly installed on the bottom of the grid 5. The cross section of the arc strip 18 is rectangular. The arc strip 18 passes through the cross bar 9 and is fixedly connected to a limit plate 19. The limit plate 19 and the ends of the arc strip 18 are connected by glue. When the cross bar 9 needs to be replaced, the glue can be heated to cancel the connection between the limit plate 19 and the arc strip 18, so that the cross bar 9 can be removed.

[0024] Before cleaning the crystals, hot air is injected into the cavity through the gas injection component, and then the hot air is blown out through the air port 20 to heat the crystals at the bottom of the grid 5. The temperature of the hot air is 50°C. By heating the crystals, the crystals are easier to detach from the grid 5 during subsequent cleaning, avoiding the situation where large crystals are attached and cannot fall off. After heating for a period of time, the driving component is used to swing and vibrate the grid 5 to clean the crystals. The crystals on the upper grid 5 fall onto the lower mesh plate 6. As the grid 5 rotates, the crystals on the mesh plate 6 can fall downward and will not remain on the grid. On the plate 6, when the grid 5 is horizontal, there is a gap between the limit plate 19 and the cross bar 9. When the grid 5 rotates, the arc strip 18 and the limit plate 19 move with it. The limit plate 19 contacts the cross bar 9 and moves with it, so that the cross bar 9 moves along the ring 17. The size of the ring 17 is sufficient for the end of the cross bar 9 to move inside. The end diameter of the cross bar 9 is smaller than the diameter of its rod body. With the rapid reset of the grid 5, it is reset against the cross bar 9. When the end of the cross bar 9 contacts the inner wall of the closed end of the ring 17, the cross bar 9 stops moving, and then the grid 5 contacts and collides with the cross bar 9, generating vibration.

[0025] like Figure 2 and Figure 4 As shown, the gas injection assembly includes a ring tube 21 fixedly connected to the bottom of the ring plate 3, wherein one column 4 passes through multiple ring tubes 21, a channel is provided inside the column 4 passing through the ring tube 21, the channel is connected to the ring tube 21, and a docking port connected to the channel is provided on the top of the column 4 passing through the ring tube 21, a gas injection machine 23 is fixedly connected to the top of the cover plate 32, a connecting pipe 24 is fixedly connected to the output end of the gas injection machine 23, the bottom of the connecting pipe 24 extends to the tank body 1 and is fixedly connected to a shell 25, an electric heating network is provided in the shell 25 (not shown in the figure), a docking pipe corresponding to the docking port is provided at the bottom of the shell 25, and the ring tube 21 is connected to the inside of the cross bar 9 through the telescopic tube 22.

[0026] Start the electric heating network and the gas injection machine 23, so that the gas injection machine 23 injects gas into the channel through the connecting pipe 24, the shell 25, and the docking tube. The air is heated by the electric heating network and has temperature. The heated air enters the cross bar 9 through the ring tube 21 and the telescopic tube 22, and is blown out through the blowing port 20 to heat the crystals at the bottom of the grid 5. When the grid 5 rotates forward, it pulls the telescopic tube 22 with the cross bar 9. When the grid 5 is reset, the telescopic tube 22 is reset conversely. When the cover plate 32 is removed, the docking tube is separated from the channel. A sealing ring is provided on the outside of the docking tube. When the cover plate 32 is reset, the docking tube is inserted into the channel to form a connection.

[0027] like Figure 2 As shown, the limiting assembly includes a pair of screw rods 29, and the bottom of the cover plate 32 is symmetrically provided with limiting grooves. The top of the screw rod 29 extends through the tank body 1 to the limiting groove and is fixedly connected to a limiting plate. The screw rod 29 and the tank body 1 are threadedly connected.

[0028] The forward rotation of the pair of screw rods 29 causes the limiting plate to rise and press against the cover plate 32 so that there is a gap between the cover plate 32 and the tank body 1. Conversely, the reverse rotation of the screw rods 29 can realize the reset of the cover plate 32. When the cover plate 32 is reset and combined with the top of the tank body 1, the limiting plate cooperates with the limit groove to prevent the cover plate 32 from rotating, making it stable, thereby ensuring the smooth operation of the motor 26.

[0029] like Figure 1 and Figure 2 As shown, the closing assembly includes a closing plate 30 arranged at the bottom of the base plate 10, and both sides of the closing plate 30 are threadedly connected with adjustment rods 31, the top of the adjustment rod 31 is rotatably mounted on the bottom wall of the tank body 1, and the screw rod 29 passes through the closing plate 30 without contacting it.

[0030] The forward rotation of the adjusting rod 31 causes the closing plate 30 to descend, thereby opening the vent 11 .

[0031] The method for pickling fish using the above-mentioned fire-cultivated fish pickling and fermentation tank with fish smell removal and drying integrated therein comprises the following steps: S1. When in use, remove the cover plate 32, take out the cylinder core 2, cancel the connection of the connecting assembly to the cylinder core 2, add lemon peel or orange peel into the cylinder core 2 as a deodorizing material, the cylinder core 2 is a net cylinder, then pull the column 4 with the ring plate 3 to move outside the tank body 1, turn the bolt 33 to separate it from the grid 5, remove the mesh plate 6, put the salted fish into the grid 5, the fish is fire-cooked fish, and the salt concentration of the pickled fish is: 3% - 8%. After putting it in, reset the mesh plate 6, connect the mesh plate 6 to the grid 5 through the bolt 33, then reset the ring plate 3 to make it located in the tank body 1, reset the cylinder core 2 and the cover plate 32, at this time, the tank body 1 is in a closed environment, and then the fish is pickled. During the pickling, microorganisms ferment on its surface; S2, after the pickling is completed, the sealing component for the vent 11 is removed, the cover plate 32 is lifted, and then a gap is formed between the cover plate 32 and the top of the tank body 1, and the outside wind enters the tank body 1 through the vent 11, and dries the fish with the smell of the deodorizing material emitted by the cylinder core 2; S3. Drive the shaft 7 to rotate forward through the driving assembly, so that the connected net frame 5 rotates accordingly. When the shaft 7 rotates, the torsion spring 8 is twisted to torsionally deform it. Then the driving assembly cancels the drive to the shaft 7. The torsion spring 8 is reset to bring the shaft 7 and the net frame 5 back to normal quickly, so that the collision between the net frame 5 and the cross bar 9 stops instantly, generating vibration, thereby shaking off the salt crystals blocked in the mesh holes at the bottom of the net frame 5, so that the mesh holes at the bottom of the net frame 5 are cleaned to ensure the ventilation effect of the bottom of the net frame 5. Subsequently, as the driving assembly works, the net frame 5 can be continuously swung to throw out the moisture in the fish and accelerate the drying effect. When the shaft 7 rotates forward, the net frame 5 rotates accordingly and can fully contact with the wind mixed with the deodorizing material, thereby improving the deodorizing effect.

[0032] Working principle: When in use, remove the cover plate 32, take out the cylinder core 2, reverse the screw 28 to separate it from the cylinder core 2, separate the cylinder core 2 from the connecting frame 27, add deodorizing material into the cylinder core 2, then turn the screw 28 forward to reset it to connect the cylinder core 2 with the connecting frame 27, and install the cylinder core 2, then pull the column 4 with the ring plate 3 to the outside of the tank body 1, turn the bolt 33 to separate it from the grid 5, remove the grid plate 6, and put the salted fish into the grid 5. The fish is fire-cooked fish, and the salt concentration for pickling is: 3% - 8%, after putting it in, reset the mesh plate 6, connect the mesh plate 6 with the grid frame 5 by bolts 33, then reset the ring plate 3 so that it is located in the tank body 1, combine the column 4 with the jack, reset the cylinder core 2 and the cover plate 32, at this time, the tank body 1 is in a closed environment, and then the fish is pickled. During the pickling, the microorganisms ferment on its surface. After the pickling is completed, the sealing component of the vent 11 is cancelled, and a pair of screw rods 29 are rotated forward so that the limiting plate rises against the cover plate 32 so that there is a gap between it and the tank body 1. At this time, the outside wind enters the tank body 1 through the vent 11, carrying the deodorizing material emitted by the cylinder core 2. The fish is air-dried with the smell. When pickled, the fish will release water after being smeared with salt, and the salt water drips on the bottom of the grid 5. After the pickling process, crystals are formed, which will block the bottom mesh of the grid 5, affecting the speed of drying by the external wind. The motor 26 is started so that its output shaft drives the connecting frame 27, the screw 28, and the cylinder core 2. The cylinder core 2 cooperates with the teeth 16 to drive the second bevel gear 14 to rotate, thereby cooperating with the first bevel gear 12 to drive the rotating shaft 7 and the grid 5 to rotate. As the rotating shaft 7 rotates, the torsion spring 8 is twisted to make it twisted and deformed. Then the toothless section on the cylinder core 2 moves to the second bevel gear 14, and the torsion spring 8 is released at this time. The force brings the rotating shaft 7 and the grid 5 to quickly reset, so that the collision between the grid 5 and the cross bar 9 stops instantly, generating vibration, thereby shaking off the salt crystals blocked in the mesh holes at the bottom of the grid 5, so that the mesh holes at the bottom of the grid 5 are cleaned, ensuring the ventilation effect at the bottom of the grid 5, and then the teeth 16 on the second bevel gear 14 mesh with the teeth 16 on the cylinder core 2 again, and then separate, so that the grid 5 can be continuously swung and vibrated, so that the moisture in the fish can be thrown out, and the drying effect is accelerated, and when the rotating shaft 7 rotates forward, the grid 5 rotates accordingly, and can fully contact with the wind mixed with the deodorizing material, so as to improve the deodorizing effect; Before cleaning the crystals, start the electric heating network and the gas injection machine 23, so that the gas injection machine 23 injects gas into the channel through the connecting pipe 24, the shell 25, and the docking pipe. The air has temperature after being heated by the electric heating network. The heated air enters the cross bar 9 through the annular tube 21 and the telescopic tube 22, and is blown out through the air port 20 to heat the crystals at the bottom of the grid 5, so that the crystals can be more easily separated from the grid 5 during subsequent cleaning, avoiding the situation where large pieces of crystals are attached and cannot fall off. After heating for a period of time, stop the gas injection machine 23 and the electric heating network, and then perform the same operation as above to clean the crystals, so as to improve the effect of cleaning the crystals.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
