Description

Technical Field

[0001] This invention belongs to the field of roughage fermentation, specifically a livestock roughage fermentation device. Background Technology

[0002] Livestock roughage refers to feed with a natural moisture content of less than 60%, a crude fiber content of no less than 18% in dry matter, and is fed in an air-dried form. Its core characteristics are large volume, hard texture, and relatively low nutritional value, but it can provide necessary dietary fiber and some nutrients. Appropriate fermentation equipment is required in the processing of livestock roughage.

[0003] In existing technologies, livestock roughage cannot be compacted layer by layer during fermentation, resulting in air remaining in the gaps between the feed. The oxygen present in these gaps inhibits the activity of anaerobic lactic acid bacteria, causing the pH value to drop slowly and failing to effectively inhibit harmful bacteria. This leads to incomplete decomposition of raw materials, significant loss of energy and protein, and reduced nutritional value of the feed, making it unsuitable for use.

[0004] Therefore, the present invention provides a livestock roughage fermentation device. Summary of the Invention

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1:

[0032] like Figures 1 to 9 As shown, an embodiment of the present invention provides a livestock roughage fermentation device, comprising a fermentation tank 1, a liquid addition pipe 2 connected and fixed to one side of the fermentation tank 1, a feed addition pipe 3 connected and fixed to one side of the fermentation tank 1 at the bottom of the liquid addition pipe 2, two sealing doors 4 installed at one end of the outer periphery of the fermentation tank 1, a filter plate 6 disposed in the inner cavity of the fermentation tank 1, and an auxiliary processing mechanism acting on the feed placed on top of the filter plate 6.

[0033] The auxiliary processing mechanism includes a compaction component that acts on the feed at the top of the filter disc 6. The compaction component includes a movable seat 5 disposed at the top of the filter disc 6, a reinforcing component disposed inside the filter disc 6, and a driving component that acts on the movable seat 5 and the filter disc 6.

[0034] The feeding pipe 3 is connected to the pipe that needs to transport the fermented feed, and the liquid adding pipe 2 is connected to the pipe that transports the bacterial liquid. When adding feed into the liquid adding pipe 2, it needs to be added gradually, and the bacterial liquid is sprayed intermittently on the feed entering the liquid adding pipe 2. The driving component enables the movable seat 5 to reciprocate in the vertical direction, compacting the feed piled on top of the filter plate 6, thereby expelling the air remaining in the gaps between the feed. During this process, the filter plate 6 rotates and, in conjunction with the reinforcing component, improves the processing effect of the feed, making the feed more compact and thus fully removing the oxygen in the gaps between the feed. This helps the feed to undergo anaerobic fermentation, thereby inhibiting the activity of aerobic bacteria such as mold and putrefactive bacteria, and creating a fermentation environment dominated by lactic acid bacteria.

[0035] like Figures 1 to 9 As shown, the driving component includes two rotating rods 42 rotatably connected to one end of the top of the fermentation tank 1, a second motor 43 fixed at the bottom of the rotating rods 42 on the top of the fermentation tank 1, a third bevel gear 44 fixedly sleeved on the outer circumferential surface of the rotating rods 42 and the output end of the second motor 43, a rotating disk 7 fixed to one end of one of the rotating rods 42, a moving frame 8 set at one end of the rotating disk 7, an abutment seat 9 inserted into the inner cavity of the moving frame 8, two openings 47 on the surface of the rotating disk 7, a hydraulic cylinder 48 fixed in the inner cavity of one of the openings 47, and a support rod 10 fixed to the bottom of the moving frame 8. The support rod 10 is slidably connected to the top of the fermentation tank 1, the bottom of the support rod 10 is fixed to the top of the movable seat 5, the abutment seat 9 is slidably connected to the other opening 47, the output end of the hydraulic cylinder 48 is fixed to the surface of the abutment seat 9, and one of the third bevel gears 44 is meshed with the other two third bevel gears 44.

[0036] When the second motor 43 is started, the meshing between the third bevel gear 44 causes the two rotating rods 42 to rotate, which in turn causes the rotating disk 7 to rotate. This, in turn, causes the contact seat 9 to rotate due to the contact action of the opening 47 against the contact seat 9. Furthermore, the contact seat 9's contact with the moving frame 8 and the limiting effect of the support rod 10 on the contact seat 9 cause the moving frame 8 to drive the support rod 10 to reciprocate vertically, thus enabling the movable seat 5 to reciprocate vertically. This allows the feed moving through the feeding pipe 3 to the top of the filter plate 6 to be compacted. Since the feed entering the inner cavity of the liquid filling pipe 2 is compacted gradually, the height of the feed will decrease after compaction, and the total height of the feed will increase when feed is added gradually in the future. Therefore, the contact seat 9 is controlled to move to the middle height of one end of the rotating plate 7. The distance between the contact seat 9 and the middle position of one end of the filter plate 6 can be adjusted by controlling the hydraulic cylinder 48, thereby adjusting the range of reciprocating motion of the movable seat 5, which can play the role of adjusting the compaction height of the feed.

[0037] like Figures 1 to 9 As shown, the driving component also includes a first motor 11 fixed to the other side of the fermentation tank 1, a movable rod 12 rotatably connected between the first motor 11 and the fermentation tank 1, a first bevel gear 13 fixedly sleeved at the output end of the first motor 11 and the middle position of the outer peripheral surface of the movable rod 12, a groove 15 opened on the inner peripheral surface of the fermentation tank 1 near the filter plate 6, a first gear ring 16 inserted into the inner cavity of the groove 15, and a first spur gear 14 fixedly sleeved at the bottom of the outer peripheral surface of the movable rod 12. The first spur gear 14 and the first gear ring 16 are meshed together. The inner peripheral surface of the first gear ring 16 is fixed to the outer peripheral surface of the filter plate 6. The two first bevel gears 13 are meshed together.

[0038] When the movable seat 5 compacts the feed under the action of the reinforcing component, the second motor 43 is turned off and the first motor 11 is started. Under the meshing action between the two first bevel gears 13, the first spur gear 14 can rotate, thereby the filter disc 6 can rotate under the meshing action between the first spur gear 14 and the first gear ring 16.

[0039] like Figures 1 to 9 As shown, the driving component also includes a rotating cylinder 41 rotatably connected to the top of the fermentation tank 1 at one side of the moving frame 8, a first pulley 17 fixedly sleeved on the outer peripheral surface of the rotating cylinder 41 and the top of the outer peripheral surface of the movable rod 12, and a first connecting belt 18 sleeved between the two first pulleys 17.

[0040] When the movable rod 12 is in a rotating state, it drives one of the first pulleys 17 to rotate, thereby enabling the other first pulley 17 to drive the rotating cylinder 41 to rotate under the connection of the first connecting belt 18.

[0041] like Figures 1 to 9 As shown, the reinforcing components include a pressure plate 22 inserted into the bottom of the inner cavity of the filter disc 6, multiple scraper strips 23 with trapezoidal cross-sections evenly fixed to the bottom of the pressure plate 22, a second gear ring 24 disposed on the top of the pressure plate 22, an annular groove 26 with a T-shaped cross-section opened in the inner cavity of the filter disc 6, a limiting block 25 with a T-shaped cross-section inserted into the inner cavity of the annular groove 26, a rotating rod 20 rotatably connected to one side of the top of the filter disc 6, a second spur gear 21 fixedly sleeved on the outer circumference of the rotating rod 20, a post 19 fixed to the top of the rotating rod 20, and first abutment blocks fixed to the bottom of the scraper strips 23 and distributed equidistantly around them. 29. A plurality of second abutment blocks 30 are fixed to the top of the pressure plate 22 and are arranged in a equidistant ring; a damper 27 is fixed at the middle position of the top of the inner surface of the filter disc 6; and a plurality of spring telescopic rods 28 are fixed to the inner surface of the filter disc 6 and located outside the damper 27. The bottom of the damper 27 is fixed to the surface of the pressure plate 22, the bottom of the spring telescopic rods 28 is fixed to the surface of the pressure plate 22, the insert 19 is slidably inserted into the rotating cylinder 41, the bottom of the limiting block 25 is fixed to the top surface of the second gear ring 24, and the second spur gear 21 is meshed with the second gear ring 24.

[0042] When the rotating cylinder 41 rotates, it abuts against the insert post 19, causing the rotating rod 20 to rotate. This allows the second sprocket 21 to mesh with the second gear ring 24. Under the supporting and limiting effect of the limiting block 25 and the annular groove 26 on the second gear ring 24, the second gear ring 24 can rotate, thereby driving multiple first abutting blocks 29 to perform circumferential motion. This allows the first abutting blocks 29 to sequentially abut against the second abutting blocks 30. Under the abutting action and the supporting effect of the spring telescopic rod 28 on the pressure plate 22, the pressure plate 22 can reciprocate vertically. The micro-vibration of the pressure plate 22 eliminates the material void layer, increasing density uniformity. The rotation of the filter disc 6 improves the uniformity of contact between the feed and the pressure plate 22. As the feed moves with the filter disc 6, the scraper 23 enhances the shear friction with the material, preventing material slippage during layering and compaction. The damper 27 improves the stability of the pressure plate 22 when stationary. After a certain period of processing the feed and achieving single compaction, the first motor 11 is turned off and the second motor 43 is turned on again, causing the movable seat 5 to move vertically upward. The above operation is repeated to achieve reciprocating compaction of the feed, improving the processing effect.

[0043] Example 2:

[0044] While the above method solves the problem of air remaining in the gaps between feed layers due to the inability to compact the feed layer by layer, in practice, when the feed is placed on the surface of the filter tray 6, impurities such as mud, sand and stones are often mixed in. If these physical contaminants are not removed, it will affect the activity of fermentation bacteria and the digestive health of animals.

[0045] like Figures 1 to 9 As shown in the comparative embodiment 1, the auxiliary processing mechanism includes a vibrating screen assembly. The vibrating screen assembly includes a fixed base 31 fixed to the bottom of the inner cavity of the fermentation tank 1, a rotating shaft 32 rotatably connected to the middle position of the fixed base 31, a movable shaft 34 rotatably connected to both ends of the fixed base 31, a second pulley 45 fixedly sleeved on the outer peripheral surface of one of the rotating rods 42 away from the rotating disk 7 and extending out of the liquid addition pipe 2 from one of the movable shafts 34, a second connecting belt 46 sleeved between the two second pulleys 45, a second bevel gear 33 fixedly sleeved on the outer peripheral surface of the rotating shaft 32 and the fixed base 31 and extending into the inner cavity of the fixed base 31, and an abutting component acting on the filter disk 6. One of the second bevel gears 33 is meshed with the two second bevel gears 33.

[0046] When another rotating rod 42 rotates, it drives one of the second pulleys 45 to rotate. Under the connection of the second connecting belt 46, the other second pulley 45 drives one of the movable shafts 34 to rotate. Thus, under the meshing action between the second bevel gears 33, the movable shaft 34 and the rotating shaft 32 rotate synchronously.

[0047] like Figures 1 to 9 As shown, the abutting component includes a sleeve 35 fixedly sleeved on both ends of the outer peripheral surface of the rotating shaft 32 and the movable shaft 34 located in the inner cavity of the fermentation tank 1, an abutting head 36 set at one end of the sleeve 35, two inner chambers 37 opened on the surface of the sleeve 35, a connecting cylinder 38 slidably inserted into the inner cavity of the inner chamber 37, a piston rod 49 slidably inserted into the inner cavity of the connecting cylinder 38, multiple air outlet pipes 40 connected and fixed to the outer peripheral surface of the connecting cylinder 38, and a connecting spring 39 fixed to the bottom of the connecting cylinder 38. One end of the connecting spring 39 is fixed to the surface of the connecting cylinder 38 at an adjacent position, and the other end of the connecting spring 39 is fixed to the inner wall of the inner chamber 37. The top of the connecting cylinder 38 is fixed to the surface of the bottom of the abutting head 36 at an adjacent position, and the bottom of the piston rod 49 is fixed to the inner cavity of the inner chamber 37.

[0048] When the rotating shaft 32 and the movable shaft 34 rotate, causing the sleeve block 35 to rotate at the contact head 36, the contact head 36 can contact the filter screen on the surface of the filter disc 6, thereby vibrating the filter screen at the middle position of the filter disc 6. This allows impurities such as mud, sand, and stones on the surface of the feed to pass through the filter screen and move to the bottom of the inner cavity of the fermentation tank 1. When the filter disc 6 contacts the filter screen, the gap between the contact head 36 and the sleeve block 35 changes, causing the connecting cylinder 38 to contact the adjacent connecting spring 39 and deform. This increases the rebound force of the connecting spring 39, which in turn enhances the vibration effect of the contact head 36 on the filter screen, thereby improving the sieving effect of the filter disc 6. Furthermore, when the contact head 36 moves away from the filter plate 6, it can be reset. When the connecting spring 39 is compressed, the piston rod 49 can move with the inner cavity of the connecting cylinder 38, thereby causing a change in air pressure in the inner cavity of the connecting cylinder 38, so that airflow can appear at the air outlet pipe 40. Under the action of airflow, the impurities accumulated on the surface between the sleeve block 35 and the contact head 36 are cleaned to avoid affecting the range of motion of the contact head 36 when it is in contact. The filter screen set on the inner wall of the air outlet pipe 40 prevents external debris from entering the inner cavity of the connecting cylinder 38. Opening the sealing door 4 can recover the fermented feed on the top of the filter plate 6 and clean the impurities at the bottom of the inner cavity of the fermentation tank 1.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
