Description

Technical Field

[0001] The present invention relates to the technical field of fermentation devices, in particular to a shrub bio-fermentation feed device with a classified feeding structure. Background Art

[0002] The shrub bio-fermentation feed device is a bio-fermentation feed production equipment specially used to process shrub raw materials (such as Leucaena leucaena, Caragana, etc.). It converts the macromolecules in the raw materials into small molecule nutrients through microbial metabolism and optimizes the fermentation environment to improve the feed quality.

[0003] Currently, existing fermentation tanks are generally welded together by welding the tank top, round tank body and conical tank bottom. When the fermentation tank is in use, it will be stirred inside, and the stirring will generate vibration. At this time, the force generated by the vibration will directly act on the fermentation tank, causing cracks in the welds of the fermentation tank. Long-term vibration will cause the cracks to grow and rupture, resulting in leakage, which in turn affects the use of the fermentation tank. In addition, when conveying the crushed leaf raw materials into the fermentation tank, since the leaves can be bent at will, the leaves will be entangled with each other to form clumps during transportation, thereby blocking the feed pipe and affecting the leaves from entering the fermentation tank.

DETAILED DESCRIPTION

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] like Figures 1-9The device shown is a shrub organism fermentation feed device with a classified feeding structure, including a fermentation tank. The fermentation tank produces carbon dioxide when fermenting shrub organisms, and the produced carbon dioxide can be treated by carbon capture technology. The fermentation tank includes a tank top 1, a circular tank body 2 and a conical tank bottom 3. The tank top 1, the circular tank body 2 and the conical tank bottom 3 are connected together by welding. A positioning and installation mechanism, a reinforcement mechanism, a limiting mechanism and a feeding mechanism are arranged between the tank top 1, the circular tank body 2 and the conical tank bottom 3. The crushed leaves can be transported into the fermentation tank through the feeding mechanism. Carbon dioxide is produced when the leaves are fermented and is captured and treated by carbon capture technology; the reinforcement mechanism includes a first reinforcement ring 8 and a second reinforcement ring 14. The inner wall of the first reinforcement ring 8 fits the outer wall of the tank top 1, and the inner wall of the second reinforcement ring 14 fits the conical tank. The outer wall of the bottom 3, the bottom end of the first reinforcement ring 8 is fixedly connected to a plurality of evenly arranged circular columns 9, and a threaded groove 23 is opened at the bottom end of each circular column 9. The top of the second reinforcement ring 14 corresponds to the circular column 9 and is rotatably connected to a plurality of evenly arranged rotating shafts 11. The top of each rotating shaft 11 is fixedly connected to a threaded column 10, and each threaded column 10 is threadedly adapted to each threaded groove 23. Each threaded column 10 rotates synchronously to move the circular column 9 and the rotating shaft 11 toward each other, thereby reinforcing the tank top 1, the circular tank body 2 and the conical tank bottom 3. The bottom of the outer wall of each rotating shaft 11 is fixedly connected to a sprocket 15, and the sprocket 15 is connected by a chain 4. The rotating shaft 11 rotates synchronously. The number of rotating shafts 11 and circular columns 9 is set to six. After the fermentation tank is reinforced, the service life of the fermentation tank can be extended.

[0020] like Figure 4 、 Figure 6 、 Figure 7 As shown, the positioning and mounting mechanism includes positioning blocks B12 fixedly connected to the outer wall of the conical tank bottom 3. The two positioning blocks B12 have different thicknesses. It also includes positioning notches B24 on either side of the inner wall of the second reinforcement ring 14. The two positioning notches B24 match the shapes of the two positioning blocks B12. The cooperation between the positioning blocks B12 and the positioning notches B24 allows the second reinforcement ring 14 to be positioned, ensuring subsequent reinforcement operations.

[0021] like Figure 7 As shown, the positioning and installation mechanism also includes expansion slots 29 at both ends of the positioning block B12. Slideways are provided on the inner walls of both sets of expansion slots 29. Sliders are slidably connected to the inner walls of each of the four sets of slideways. Limiting posts 28 are fixedly connected between the four sets of slides. The four limiting posts 28 are respectively located on the inner walls of the four expansion slots 29. Springs 30 are fixedly connected between the four sets of limiting posts 28 and the expansion slots 29. The cooperation of the slides and slideways allows the limiting posts 28 to be positioned. When the limiting posts 28 extend out of the expansion slots 29, they can limit the position of the second reinforcement ring 14, completing the installation of the second reinforcement ring 14.

[0022] like Figure 1 、 Figure 4 As shown, the positioning and mounting mechanism also includes positioning blocks A7 fixedly connected to both sides of the top of the tank roof 1 and positioning notches A25 provided on both sides of the inner wall of the first reinforcement ring 8. The two positioning blocks A7 have different thicknesses, and the shapes of the two positioning blocks A7 and the two positioning notches A25 are compatible. The cooperation between the positioning blocks A7 and the positioning notches A25 can position the first reinforcement ring 8, facilitating subsequent reinforcement operations.

[0023] like Figure 3 、 Figure 5 As shown, the limiting mechanism includes telescopic columns 22 that slide through the second reinforcement ring 14 on both sides of one of the rotating shafts 11. A circular plate 17 is fixedly connected to the top of the two telescopic columns 22. The rotating shaft 11 passes through the circular plate 17, and a polygonal groove 26 is formed at the top of the circular plate 17. A polygonal block 16 is fixedly connected to the outer wall of one of the rotating shafts 11 above the circular plate 17. The polygonal block 16 and the polygonal groove 26 are of matching shapes. When reinforcement is required, the polygonal block 16 and the polygonal groove 26 are separated, and the polygonal block 16 is rotated, thereby rotating one of the rotating shafts 11.

[0024] like Figure 5 As shown, the limiting mechanism also includes a connecting plate 20 fixedly connected to the bottom end of the telescopic column 22, and a tension spring 19 is fixedly connected between the connecting plate 20 and the second reinforcement ring 14. The two telescopic columns 22 are provided with a square groove 27 at one end away from the conical tank bottom 3. The two telescopic columns 22 are fixedly connected to the bottom of the square groove 27 at one end corresponding to the two telescopic columns 22. The other ends of the two ropes 18 are fixedly connected to the square column 21, and the shapes of the two square columns 21 and the two square grooves 27 are adapted to each other. When the reinforcement is completed, the square column 21 in the square groove 27 is pulled out to release the limit on the telescopic column 22. At this time, the connecting plate 20 can be moved upward by the reset effect of the tension spring 19. The connecting plate 20 moves upward with the telescopic column 22 and the circular plate 17. Since the corners of the polygonal groove 26 and the polygonal block 16 are not completely aligned, the polygonal block 16 is continued to be twisted until the corners of the polygonal block 16 and the polygonal groove 26 are completely aligned, and the polygonal groove 26 is stuck on the outer wall of the polygonal block 16, completing the limit on the polygonal block 16, thereby preventing the fermentation tank from loosening during use and ensuring the reinforcement effect.

[0025] like Figure 9As shown, the feeding mechanism includes a feed pipe 5 fixedly extending through both sides of the top of the tank roof 1. The bottom of the inner wall of each feed pipe 5 is fixedly connected to a limit plate 38. The top of each limit plate 38 is rotatably connected to a stirring shaft 31. The two stirring shafts 31 rotate and extend through the two feed pipes 5 respectively. The outer walls of the two stirring shafts 31 are fixedly connected to a plurality of stirring blades 37. The stirring shafts 31 rotate with the stirring blades 37, thereby clearing the interior of the feed pipe 5, preventing the broken leaves from tangling and clumping, and avoiding feed blockage. When the leaves enter the fermentation tank for fermentation, they can produce carbon dioxide, which is captured and processed by carbon capture technology.

[0026] like Figure 8 、 Figure 9 As shown, the feeding mechanism also includes a motor 6 fixedly connected to the top of the tank top 1, the driving end of the motor 6 is fixedly connected to the driving shaft 32, the outer wall of the driving shaft 32 is rotatably connected to the fixing frame 33, the fixing frame 33 and the two feeding pipes 5 are fixedly connected, the outer wall of the driving shaft 32 is fixedly connected to a plurality of elastic rods 35 corresponding to the bottom of the fixing frame 33, each elastic rod 35 is fixedly connected to a knocking ball 36 at one end away from each other, the two stirring shafts 31 and the top of the driving shaft 32 are fixedly connected to the synchronous wheel 34, the synchronous wheel 34 is connected by a synchronous belt, and the bottom end of the conical tank bottom 3 is fixedly connected to the electromagnetic valve 13 through the discharge pipe. The motor 6 rotates with the driving shaft 32, and the driving shaft 32 rotates with the elastic rod 35 and the knocking ball 36, so that the knocking ball 36 can knock on the outer wall of the feeding pipe 5, further preventing the occurrence of blockage and ensuring the smooth classification of feeding. When the fermentation is completed, the electromagnetic valve is opened to discharge the feed in the fermentation tank.

[0027] Working principle: First, the second reinforcement ring 14 can be positioned by the cooperation of the positioning block B12 and the positioning notch B24, and the direction can be identified due to the different thicknesses of the positioning blocks B12 on both sides. When the second reinforcement ring 14 is installed on the conical tank bottom 3, the positioning notch B24 first contacts the inclined surface on the limiting column 28, so that the limiting column 28 is received in the telescopic groove 29. When the inner wall of the second reinforcement ring 14 is completely in contact with the outer wall of the conical tank bottom 3, the elastic reset effect of the spring 30 can make the limiting column 28 pop out, completing the positioning and installation of the second reinforcement ring 14. Afterwards, the first reinforcement ring 8 is positioned by the cooperation of the positioning block A7 and the positioning notch A25, so that the circular The centers of the polygonal column 9 and the rotating shaft 11 are on the same vertical line. At this time, the polygonal block 16 is rotated by a tool and one of the rotating shafts 11 is rotated. Due to the cooperation of the sprocket 15 and the chain 4, the six rotating shafts 11 can be rotated synchronously, thereby rotating the threaded column 10 synchronously. The spiral directions of the six rotating shafts 11 are the same. When rotating, they will be synchronously screwed into the thread groove 23, thereby generating a pulling force between the rotating shaft 11 and the circular column 9. The pulling force acts on the first reinforcement ring 8 and the second reinforcement ring 14, so that the tank top 1, the circular tank body 2 and the conical tank bottom 3 can be reinforced to avoid cracks in the welds caused by the vibration generated by stirring during long-term fermentation, thereby ensuring the normal fermentation use of the fermenter; After the reinforcement is completed, the square column 21 in the square groove 27 is pulled out to release the limit of the telescopic column 22. At this time, the connecting plate 20 can be moved upward by the reset effect of the tension spring 19. The connecting plate 20 moves upward with the telescopic column 22 and the circular plate 17. Since the corners of the polygonal groove 26 and the polygonal block 16 are not completely aligned, the polygonal block 16 is further twisted until the corners of the polygonal block 16 and the polygonal groove 26 are completely aligned and the polygonal groove 26 is stuck on the outer wall of the polygonal block 16, thereby completing the limit of the polygonal block 16, thereby preventing the fermentation tank from loosening during use and ensuring the reinforcement effect. When the crushed leaves are transported into the fermentation tank through the feed pipe 5, the starting motor 6 drives the drive shaft 32 to rotate, and the drive shaft 32 drives one of the synchronous wheels 34. Due to the presence of the synchronous belt, the three synchronous wheels 34 can rotate synchronously, thereby driving the stirring shaft 31 and the stirring blades 37 to rotate, which can stir and disperse the crushed leaves to prevent them from being entangled into balls, thereby preventing blockage in the feed pipe 5. The drive shaft 32 also rotates with the elastic rod 35 and the knocking ball 36, so the knocking ball 36 can knock on the outer wall of the feed pipe 5 and make the scattered leaves fall quickly, further preventing blockage and ensuring smooth classified feeding. When the leaves enter the fermentation tank, they are fermented and the carbon dioxide generated at this time is captured and processed by carbon capture technology. When the fermentation is completed, the solenoid valve 13 is opened to discharge the feed.
