Description

Technical Field

[0001] The present invention relates to the technical field of feed fermentation, and particularly to a fermentation device for microbial fermentation feed ingredients. Background Art

[0002] A fermentation device for microbial fermentation feed ingredients is a device specifically used for preparing microbial fermentation feed. It provides a suitable growth environment for microorganisms by automatically controlling the batching and fermentation processes, promotes the fermentation of feed raw materials by microorganisms, and thus improves the nutritional value and palatability of the feed.

[0003] After retrieval, a Chinese patent with the publication number CN218778924U discloses a fermentation device for producing feed, which includes a barrel mechanism for containing feed and fermentation liquid, and also includes two stirring mechanisms symmetrically arranged up and down with opposite rotation directions. A sealing mechanism for sealing the barrel mechanism with water is installed on the upper part of the barrel mechanism, and a collection mechanism for collecting waste gas generated by feed fermentation is installed outside the barrel mechanism; the stirring mechanism includes a motor, a stirring shaft is installed at the driving end of the motor, and six stirring blades are evenly installed on both sides of the stirring shaft. The fermentation device for producing feed described in the above solution ensures more uniform stirring of feed and fermentation liquid through the setting of two stirring mechanisms with opposite rotation directions; improves the sealing performance of the fermentation device through the setting of sealing the feed hopper with water; and avoids environmental pollution caused by fermentation gas and reduces the emission of harmful gases through the setting of an air extraction pump and a gas collection tank. However, when the above solution is actually used, there are still the following deficiencies:

[0004] The above solution uses the stirring function to mix feed and fermentation strains. Since the fermentation strains are directly sprayed on the surface of the feed, it is impossible to fully mix the feed and the fermentation strains only by stirring. Since the fermentation strains are directly sprayed on the surface of the feed, there may be large gaps between feed particles, and the stirrer may not be able to effectively disperse the fermentation strains in these gaps to each feed particle during rotation, resulting in some feed particles not fully contacting the fermentation strains, thus affecting the fermentation effect.

[0005] Therefore, it is necessary to design a fermentation device for microbial fermentation feed ingredients to solve the above problems. Summary of the Invention

[0025] 1.

This design replaces the traditional method of only spraying strains on the surface of the feed, ensuring that the strains can penetrate deep into the feed, greatly improving the mixing uniformity of the strains and the feed, and being beneficial to enhancing the fermentation effect. The entire fermentation process is highly automated. From the feeding of the feed, the spraying of the strains, the vibrating of the supporting plate to the opening of the supporting plate and the stirring of the feed, all are automatically completed by mechanical devices, which not only greatly saves labor costs but also improves work efficiency.

[0026] 2. The vibration mechanism can effectively promote the uniform distribution and leveling of the feed. When the feed falls onto the two closed supporting plates through the discharge valve, due to the vibration of the supporting plate following the mounting ring, the feed is quickly and evenly leveled under the action of vibration. This not only improves the stacking density and uniformity of the feed but also is beneficial to the uniformity of subsequent strain spraying and the uniformity of the fermentation process.

[0027] 3. By setting up a rotating assembly, the strains can be evenly and comprehensively sprayed on the surface of the feed on the two supporting plates. The strains are fed into the feeding pipe by a pump, then enter the rotating pipe through the connecting pipe, and finally are sprayed out by several nozzles. This process is closely linked to the actions of the convex block pushing the fixed rod, the first rack driving the first gear to rotate, and the rotation of the rotating pipe driven by the bevel gear transmitted to the second shaft rod, realizing the synchronous progress of strain spraying and rotation of the rotating pipe. This design not only improves the uniformity of strain spraying but also promotes the full mixing of the strains and the feed, ensuring that each grain of feed can be effectively covered by the strains.

The material receiving assembly also includes a mounting ring 31, two fixing rods 32, two collar rings 33 and two tension springs 36. The mounting ring 31 is arranged on the inner top of the fermentation tank 11. A circular enclosure is fixed on the top surface of the mounting ring 31. The two supporting plates 35 are rotatably installed on the bottom surface of the mounting ring 31. The two fixing rods 32 are both fixed on the outer peripheral surface of the mounting ring 31.

One end of the wire 44 is connected to the wire winding wheel 43, and the other end is connected to the supporting plate 35;

[0046] The driving unit includes a lifting component, a rotating component and a pushing component. The lifting component is arranged on the outer peripheral surface of the fermentation tank 11.

The lifting component includes two fixed seats 51, a reciprocating screw rod 52, a lifting seat 53, two guide rods 54, a push plate 57 and a plurality of protrusions 58. The two fixed seats 51 are fixed in the machine cover 15. The reciprocating screw rod 52 is rotatably assembled between the two fixed seats 51. The two guide rods 54 are fixed between the two fixed seats 51.

Under the pushing action of the plurality of protrusions 58, and at the same time with the elastic action of the two first springs 34, the fixing rod 32 can drive the mounting ring 31 to vibrate continuously, so that the mounting ring 31 and the two supporting plates 35 produce a vibration effect. When the discharge valve is opened, the feed in the feed hopper 21 can fall into the fermentation tank 11 through the discharge pipe 22, and fall on the two supporting plates 35 in the closed state.

In the process of the plurality of protrusions 58 pushing the fixed rod 32, the first rack 61 can also mesh with the first gear 63 and drive the first gear 63 to rotate. When the first gear 63 rotates, it can drive the first shaft 62 to rotate. The first shaft 62 and the second shaft 64 are meshed through two bevel gears 65. The rotation of the first shaft 62 will be transmitted to the second shaft 64. When the second shaft 64 rotates, it can drive the rotating tube 17 to rotate through the second transmission member 66. Based on the above process, the bacterial spraying action of the plurality of nozzles is synchronized with the rotation action of the rotating tube 17, so that the bacterial strain can be evenly and comprehensively sprayed on the surface of the feed, so that the bacterial strain and the feed are fully mixed, thereby ensuring the fermentation effect of the device on the feed;

[0048] The driving assembly includes two air supply components and two actuating components. The two air supply components are both arranged on the fixed seat 51 at the top, and the two actuating components are both arranged inside the fermentation tank 11. The two actuating components are respectively arranged opposite to the two wire reels 43. The air supply component includes a first sealing cylinder 71 and a first sliding rod 72. The first sealing cylinder 71 is fixed on the fixed seat 51 at the top. The first sliding rod 72 is sealingly and slidably connected inside the first sealing cylinder 71, and the bottom end of the first sliding rod 72 extends to the outside of the first sealing cylinder 71.

The second gear 79 is fixedly sleeved on the axle 42, and the second gear 79 is arranged opposite to the second rack 78. For the air supply component, when the first sliding rod 72 moves under the pushing action of the lifting seat 53, the first sliding rod 72 can push the gas in the first sealing cylinder 71 into the second sealing cylinder 74 through the hose 77. When the gas enters the second sealing cylinder 74, the gas will push the second sliding rod 75 to move. When the second sliding rod 75 moves downward, it drives the second rack 78 to move downward. In this process, the second rack 78 can drive the second gear 79 to rotate, so that the axle 42 rotates. Based on the above process, when the lifting seat 53 drives the two air supply components to operate, the two axles 42 can rotate synchronously, so that the two wire reels 43 rotate synchronously. When the two wire reels 43 rotate, they can wind up the two pulling ropes. When the pulling ropes are wound up, the pulling ropes can pull the material supporting plate 35, so that the material supporting plate 35 rotates. When the two material supporting plates 35 rotate, the feed piled on the two pushing plates will fall into the inner bottom of the fermentation tank 11 under the action of gravity, realizing automatic feeding.

[0049] The specific working principle of the present invention is as follows:

[0050] When the microbial fermentation feed ingredient fermentation device proposed by the present invention is in use, the staff transfers the feed to the feed hopper 21 through a screw conveyor or other feeding device. An electric discharge valve 23 is installed on the discharge pipe 22 at the bottom of the feed hopper 21 to control the intermittent discharge of the feed. A motor 12 is installed at the bottom of the fermentation tank 11. When the motor 12 operates, it can drive the stirring shaft 13 to rotate. When the stirring shaft 13 rotates, several stirring blades 14 thereon rotate accordingly to stir the feed falling into the interior of the fermentation tank 11. In addition, when the motor 12 operates, it can also drive the transmission rod 55 to rotate through the first transmission member 56. When the transmission rod 55 rotates, it drives the reciprocating lead screw 52 to rotate. Under the limiting action of the two guide rods 54, when the reciprocating lead screw 52 rotates, it can drive the lifting seat 53 to move up and down reciprocally. When the lifting seat 53 moves, the push plate 57 thereon moves accordingly. During the process of the lifting seat 53 moving upward from bottom to top, several convex blocks 58 on the push plate 57 will first come into contact with the opposite fixed rod 32. When the push block presses the fixed rod 32, the fixed rod 32 will move and drive the mounting ring 31 to move. When the gap between the two convex blocks 58 moves to the position opposite the fixed rod 32, the fixed rod 32 will move between the two convex blocks 58 under the elastic force of the first spring 34. Therefore, under the pushing action of several convex blocks 58 and in cooperation with the elastic force of the two first springs 34, the fixed rod 32 can drive the mounting ring 31 to vibrate continuously, which makes the mounting ring 31 and the two supporting plates 35 produce a vibrating effect. When the discharge valve is opened, the feed in the feed hopper 21 can fall into the fermentation tank 11 through the discharge pipe 22 and land on the two supporting plates 35 in a closed state. When the supporting plates 35 vibrate following the mounting ring 31, the feed falling on the two supporting plates 35 can be leveled under the action of vibration;

[0051] When the mounting ring 31 vibrates, the staff uses a pump to supply the bacterial strain into the feed pipe 16, so that the bacterial strain enters the rotating pipe 17 through the connecting pipe 110. Further, the bacterial strain can be ejected through several nozzles 18 and sprayed on the surface of the feed on the two supporting plates 35. During the process of several convex blocks 58 pushing the fixed rod 32, the first rack 61 can also be engaged with the first gear 63 and drive the first gear 63 to rotate. When the first gear 63 rotates, it can drive the first shaft 62 to rotate. The first shaft 62 and the second shaft 64 are engaged with each other through two bevel gears 65. The rotation action of the first shaft 62 will be transmitted to the second shaft 64. When the second shaft 64 rotates, it can drive the rotating pipe 17 to rotate through the second transmission member 66. Based on the above process, the bacterial strain spraying action of several nozzles is synchronized with the rotation action of the rotating pipe 17, which makes the bacterial strain be sprayed on the surface of the feed evenly and comprehensively, and enables the bacterial strain to be fully mixed with the feed, thereby ensuring the fermentation effect of the device on the feed;

[0052] With the continuous upward movement of the lifting seat 53, several bumps 58 on the push plate 57 will be separated from the corresponding fixed rods 32, which causes the mounting ring 31 to stop vibrating. After several bumps 58 are separated from the corresponding fixed rods 32, the first rack 61 will also be separated from the first gear 63. Further, the lifting seat 53 will push the two first sliding rods 72 upward, causing the two air supply components to operate synchronously. For the air supply components, when the first sliding rod 72 moves under the pushing action of the lifting seat 53, the first sliding rod 72 can push the gas in the first sealing cylinder 71 into the second sealing cylinder 74 through the hose 77. When the gas enters the second sealing cylinder 74, the gas will push the second sliding rod 75 to move. When the second sliding rod 75 moves downward, it drives the second rack 78 to move downward. In this process, the second rack 78 can drive the second gear 79 to rotate, causing the axle 42 to rotate. Based on the above process, when the lifting seat 53 drives the two air supply components to operate, the two axles 42 can rotate synchronously, causing the two wire reels 43 to rotate synchronously. When the two wire reels 43 rotate, they can wind up the two pulling ropes. When the pulling ropes are wound up, the pulling ropes can pull the material supporting plate 35, causing the material supporting plate 35 to rotate. When the two material supporting plates 35 rotate, the feed stacked on the two pushing plates will fall to the inner bottom of the fermentation tank 11 under the action of gravity. In summary, under the combined action of the fermentation unit, the feeding unit, the material receiving unit, and the driving unit, the feed will intermittently fall on the two material supporting plates 35. After the surface of the feed is evenly sprayed with the bacterial strain, the two material supporting plates 35 rotate and perform an opening action, causing the feed covered with the bacterial strain on the surface to fall into the fermentation tank 11. Finally, several stirring heads stir the feed. This design enables the feed and the bacterial strain to be fully mixed, replacing the traditional method of only spraying the bacterial strain on the surface of the feed, and can ensure the fermentation effect of the device on the feed;

[0053] It should be noted that the start and stop times of the discharge valve and the pumping time of the bacterial strain can both be controlled by an automated program. This is prior art and is not shown in the figure and will not be elaborated here.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
