Description

Technical Field

[0001] The utility model belongs to the technical field of silage fermentation, and in particular relates to silage fermentation equipment. Background Art

[0002] Silage is a type of feed made from water-rich plant-based feed that has been sealed and fermented. It is primarily used to feed ruminants. Silage is more durable than fresh feed and contains more nutrients than dry feed. Silage is compacted and sealed, creating a lack of oxygen inside. Lactic acid bacteria ferment and decompose sugars, producing carbon dioxide that further displaces air. The resulting lactic acid makes the feed slightly acidic (pH 3.5-4.2), effectively inhibiting the growth of other microorganisms.

[0003] Existing fermentation equipment typically compacts silage by manually trampling or hammering it with stakes after adding it. This method has poor compaction effects, resulting in a large amount of air remaining in the fermentation tank, causing the feed to rot and deteriorate. It is also time-consuming and labor-intensive, and therefore needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1: Figure 1-6 As shown, a silage fermentation equipment of the present invention includes a fermentation tank 1, a hollow column 11 rotatably connected to the fermentation tank 1 is installed inside the fermentation tank 1, a brake motor 12 transmission-connected to the hollow column 11 is installed at the lower end of the fermentation tank 1, a stirring assembly is installed on the side of the hollow column 11, an internal threaded cylinder 13 is installed at the upper end of the hollow column 11, a lifting column 14 is threadedly connected to the internal threaded cylinder 13, a sealing plate 15 is fixedly installed on the upper end of the lifting column 14, a U-shaped block 16 is symmetrically fixedly connected to the upper end of the fermentation tank 1, a slide matching the two U-shaped blocks 16 is opened inside the fermentation tank 1, the sealing plate 15 is fixedly connected to a first slider 17 sealingly and slidingly connected to the U-shaped block 16, a leakage groove 18 is opened at the bottom of the fermentation tank 1, a discharge pipe 19 connected to the leakage groove 18 is installed at the lower end of the fermentation tank 1, and an electromagnetic valve is installed on the discharge pipe 19.

[0023] During use, the sealing cover 15 is separated from the internal threaded cylinder 13 to facilitate the placement of the feed to be fermented into the fermentation tank 1, and then silage additives such as fermentation-promoting additives, fermentation-inhibiting additives, and spoilage bacteria inhibitors are added. The brake motor 12 is then started to drive the hollow column 11 and the internal threaded cylinder 13 to rotate, and then the stirring assembly is driven to rotate with the hollow column 11 to mix the feed and additives. When the mixing is completed, the sealing plate 15 and the lifting column 14 are driven to be inserted into the internal threaded cylinder 13 and the first slider 17 is slid into the U-shaped block 16. At this time, the brake motor 12 is started again to drive the hollow column 11 and the internal threaded cylinder 13 to rotate. Since the internal threaded cylinder 13 is threadedly connected to the lifting column 14, and the first slider 17 is sealed and slidably connected to the U-shaped block 16, when the internal threaded cylinder 13 rotates, it will drive the lifting column 14 to move downward, thereby squeezing and compacting the feed, and discharge the air inside the fermentation tank 1 through the leakage groove 18 and the discharge pipe 19. After the feed is compacted, the electromagnetic valve is closed to prevent outside air from entering the fermentation tank 1 through the discharge pipe 19. In this way, a closed space is formed inside the fermentation tank 1, which is conducive to the anaerobic fermentation of the feed. The liquid produced during the fermentation process will enter the leakage groove 18 through the filter holes at the bottom of the fermentation tank 1, avoiding contact between the liquid and the feed and affecting the fermentation effect.

[0024] The utility model can drive the stirring assembly to mix additives and feed raw materials through the hollow column, and can also drive the lifting column and the sealing plate to press the feed downward under the drive of the brake motor after the mixing is completed, thereby reducing the air staying inside the fermentation tank, shortening the formation time of the anaerobic environment and accelerating the fermentation efficiency.

[0025] Example 2: Further improvement is made on the basis of Example 1, the stirring assembly includes three groups of stirring members, and the three groups of stirring members include a horizontal axis 20 symmetrically installed on both sides of the hollow column 11, and a number of stirring rods 21 are fixedly connected to the sides of the horizontal axis 20. The middle group of stirring members is staggered with the stirring members on the upper and lower sides.

[0026] When the hollow column 11 drives the horizontal shaft 20 to rotate, it will drive the horizontal shaft 20 to revolve around the output end of the brake motor 12 as the center, and the stirring rods 21 staggered up and down can increase the range of action of the stirring rods 21 and improve the mixing efficiency.

[0027] The hollow column 11 is rotatably connected to a vertical shaft 22, and a rectangular block 23 is fixedly connected to the upper end of the vertical shaft 22. The horizontal shaft 20 rotates through the hollow column 11 and is fixedly connected to a first conical tooth 24. The vertical shaft 22 is fixedly installed with a second conical tooth 25 that matches the three groups of stirring members. The first conical teeth 24 and the second conical teeth 25 at the same level are engaged with each other. The rectangular block 23 and the internal threaded cylinder 13 are slidably connected to a limit rod 26. The limit rod 26 is fixedly connected to a tank cover 27 that is slidably connected to the U-shaped block 16.

[0028] When it is necessary to mix the auxiliary agent and the feed, the tank cover 27 and the limiting rod 26 are preferably inserted into the U-shaped block 16 and the internal threaded cylinder 13. The limiting rod 26 cannot rotate under the cooperation of the rectangular block 23 and the U-shaped block 16, and then the tank cover 27 and the limiting rod 26 limit the rectangular block 23 and the vertical shaft 22 and cannot rotate. At this time, starting the brake motor 12 to drive the hollow column 11 to rotate will drive the horizontal shaft 20 and the first conical gear 24 to rotate. Since the vertical shaft 22 is connected to the hollow column 11 in rotation, and The first conical teeth 24 and the second conical teeth 25 are meshed with each other, so the first conical teeth 24 will mesh with the second conical teeth 25 and rotate with them as the center. If the second conical teeth 25 cannot rotate, the first conical teeth 24 will drive the horizontal shaft 20 to rotate, and then drive the stirring rod 21 to rotate. During the process of the stirring rod 21 rotating horizontally with the vertical shaft 22 as the center, it will also rotate longitudinally with the horizontal shaft as the center. The stirring rod 21 rotating in different directions improves the mixing efficiency of the feed and the auxiliary agent.

[0029] The bottom side of the fermentation tank 1 is inclined from the periphery to the hollow column 11, and the leakage groove 18 is inclined from the hollow column 11 to the periphery. The inclined bottom side of the fermentation tank 1 facilitates the liquid produced by fermentation to enter the leakage groove 18 for storage, and the inclined leakage groove 18 facilitates the discharge of the liquid.

[0030] Handles 28 are symmetrically mounted on the upper ends of the sealing plate 15 and the tank cover 27 .

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
