Description

Technical Field

[0002] In the poultry farming industry, duck farming has high requirements on the nutritional value and quality of feed, which is directly related to the growth quality of ducks. The feed cost in farming usually accounts for 60%-70% of the total farming cost.

Commonly used feed raw materials for ducks include grains, soybean meal, silage, etc.

[0003] In the prior art, the above feed raw materials are usually mixed and then anaerobically fermented before feeding. During the anaerobic fermentation process, microorganisms will decompose the non-digestible components in the raw materials and convert them into nutrient-rich metabolites, thereby increasing the protein content and biological availability of the feed. In addition, the organic acids produced during the fermentation process can effectively inhibit the growth of harmful bacteria, reduce the occurrence of digestive tract diseases in ducks, and improve their immunity. When fermenting feed, a fermentation tank is usually used for fermentation, but the mixing of the feed raw materials in the fermentation tank may be uneven, resulting in uneven distribution of microorganisms during the fermentation process, affecting the fermentation effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

By chopping the raw materials to be fermented through the opposite rotation of the two groups of chopping mechanisms, the raw materials to be fermented can be more evenly distributed between the two chopping knives, thereby improving the chopping efficiency, and preventing the raw materials to be fermented from being blocked between the chopping knives, which is conducive to the subsequent sufficient mixing of the raw materials.

[0042] In order to ensure that the rotation directions of the first chopping knife 3 and the second chopping knife 5 are always opposite, the sleeve 4 extends to the outside of the working cylinder 1 and is fixedly connected to an auxiliary gear 9. The bottom of the working cylinder 1 is rotatably connected to a connecting rod 7, and a main gear 8 is fixedly connected to the connecting rod 7. The main gear 8 is meshed with the auxiliary gear 9. A first pulley 10 is fixedly connected to the connecting rod 7. The rotating shaft 2 extends to the outside of the working cylinder 1 and is fixedly connected to a second pulley 11. The first pulley 10 is connected to the second pulley 11 through a belt.

During this process, the auxiliary gear 9 rotates in opposite directions to the main gear 8, while the connecting rod 7 rotates in the same direction as the rotating shaft 2, so that the rotation directions of the rotating shaft 2 and the sleeve 4 are always opposite.

[0044] The conveying guide mechanism inside the conveying cylinder 13 can convey the raw materials to be fermented, and can repeatedly convey the chopped raw materials inside the working cylinder 1 to the conveying cylinder 13, and then be transported by the conveying cylinder 13 to the working cylinder 1 for repeated chopping, so that the raw materials to be fermented can be repeatedly chopped, so that the raw materials can be chopped more evenly, which helps to improve the subsequent fermentation effect.

[0046] In order to improve the fermentation effect of the raw materials to be fermented, the above-mentioned conveying guiding mechanism further includes a spiral plate 43, a conveying rod 18 is rotatably connected inside the conveying cylinder 13, the spiral plate 43 is fixedly connected to the outer wall of the conveying rod 18, and the edge of the spiral plate 43 fits with the inner wall of the conveying cylinder 13, the upper side wall of the conveying cylinder 13 is connected to the top of the working cylinder 1 through the second pipe 15, the bottom of the working cylinder 1 is connected to the lower side wall of the conveying cylinder 13 through the first pipe 14, and the conveying cylinder 13 is connected to the top of the mixing cylinder 19 through the third pipe 16.

[0047] Control valves are provided on the first pipeline 14, the second pipeline 15 and the third pipeline 16 for controlling the passage of the pipelines. When the raw materials are circulated and shredded, the passage of the third pipeline 16 is closed, while the passages of the first pipeline 14 and the second pipeline 15 are always open.

[0048] When the chopped raw materials need to be fermented, the passage of the third pipe 16 is opened and the passage of the second pipe 15 is closed. A spiral tube 17 is also provided in the working cylinder 1. When the third pipe 16 transports the raw materials, they are transported into the spiral tube 17, so that the raw materials can be rotated and discharged, so that they can cooperate with the shredding mechanism to improve the shredding effect of the raw materials.

[0049] The rotating shaft 2 is fixedly connected with a third pulley, the transmission rod 18 extends to the outside of the transmission cylinder 13 and is fixedly connected with a fourth pulley, and the third pulley is connected with the fourth pulley through a belt drive.

[0050] When the rotating shaft 2 rotates, the third pulley and the fourth pulley are connected by belt drive, which will drive the conveying rod 18 to rotate synchronously, and then the spiral plate 43 rotates synchronously with the conveying rod 18, so that the edge of the spiral plate 43 moves along the inner wall of the conveying cylinder 13, so that the raw materials are continuously transported from the bottom to the top.

[0051] The heating tube 22 in the mixing barrel 19 can heat the raw materials to keep them in a suitable fermentation temperature range, and a temperature sensor 23 is also provided in the mixing barrel 19 to monitor the temperature in real time.

[0053] In order to put the mixing drum 19 in an anaerobic state, the gas generated in the mixing drum 19 can be pumped out to the outside through the exhaust mechanism, so that the fermentation raw materials in the mixing drum 19 are in an anaerobic state, thereby preventing oxygen from entering the mixing drum 19 and preventing oxidation reaction of the raw materials.

[0054] Furthermore, the above-mentioned vacuum mechanism includes a booster cylinder 38 fixedly connected to the bottom of the mixing cylinder 19, and a booster rod 39 is slidably connected to the booster cylinder 38. A piston is provided on the booster rod 39, and the piston is in contact with the inner wall of the booster cylinder 38. An air inlet pipe 40 and an air outlet pipe 41 are respectively provided on the booster cylinder 38, and both the air inlet pipe 40 and the air outlet pipe 41 are provided with a one-way valve, and the air inlet pipe 40 is connected to the top of the mixing cylinder 19.

[0055] When the boost rod 39 slides on the boost cylinder 38, the boost rod 39 will drive the piston to move against the inner wall of the boost cylinder 38. When the boost rod 39 moves toward the outside of the boost cylinder 38, negative pressure will be generated inside the boost cylinder 38, and the air inlet pipe 40 will transport the gas in the mixing cylinder 19 to the boost cylinder 38 for replenishment. During this process, the gas in the mixing cylinder 19 is extracted, the air outlet pipe 41 stops exhausting, and a filter is provided on the air inlet pipe 40 to prevent the raw materials in the mixing cylinder 19 from entering the air inlet pipe 40. When the boost rod 39 moves toward the inside of the boost cylinder 38, the piston will pressurize the internal gas, and then transport the gas in the mixing cylinder 19 to the outside through the air outlet pipe 41. The gas can be collected and utilized as needed. During this process, the air inlet pipe 40 stops intake.

[0056] In addition, a support plate 24 is fixedly connected to the side wall of the mixing barrel 19, a transmission shaft 28 is rotatably connected to the support plate 24, a first crank 30 is rotatably connected to the transmission shaft 28, a second crank 31 is rotatably connected to the first crank 30, a slider 32 is rotatably connected to the second crank 31, and an end of the boost rod 39 away from the piston is fixedly connected to the slider 32.

[0057] When the transmission shaft 28 rotates, the first crank 30 and the second crank 31 rotate in coordination, which can drive the slider 32 to move back and forth, and then the slider 32 drives the boost rod 39 to slide back and forth on the boost cylinder 38.

[0058] The support plate 24 is fixedly connected with a motor 12 , and the connecting rod 7 is fixedly connected to the output end of the motor 12 . The motor 12 can drive the connecting rod 7 to rotate.

[0059] In order to improve the uniform fermentation effect of the raw materials in the mixing drum 19, a connecting shaft 20 is rotatably connected inside the mixing drum 19, a stirring paddle 21 is fixedly connected to the outer wall of the connecting shaft 20, the connecting shaft 20 extends to the outside of the mixing drum 19 and is fixedly connected to a connecting gear 34, a transmission rack 33 is fixedly connected to the slider 32, and the transmission rack 33 is meshed with the connecting gear 34.

[0060] When the slider 32 moves back and forth, it will drive the transmission rack 33 to move synchronously, and then the transmission rack 33 drives the connecting gear 34 to rotate back and forth, and the connecting gear 34 drives the connecting shaft 20 to rotate back and forth, so that it can rotate clockwise for one circle and then counterclockwise for one circle, so that the stirring paddle 21 can rotate back and forth in the mixing barrel 19 to stir the fermented raw materials.

[0061] By reciprocating the stirring paddle 21 in the mixing barrel 19, the fermentation raw materials can be effectively mixed to avoid material precipitation or stratification, thereby improving the mixing uniformity and the fermentation effect. In addition, when stirring, the stirring paddle 21 will quickly discharge the gas that may be mixed in the raw materials, and then extract the gas through the exhaust mechanism, which helps to maintain a suitable fermentation environment.

[0062] In order to improve the practicability of the device, the stirring blade 21 and the air extraction mechanism can be started as needed.

[0063] A telescopic member 35 is provided on the support plate 24, and a telescopic rod 36 is fixedly connected to the output end of the telescopic member 35, and a mounting plate 44 is fixedly connected to the telescopic rod 36, and a mounting shaft 37 is rotatably connected to the mounting plate 44, and a movable gear 26 is fixedly connected to the mounting shaft 37, and the transmission rod 18 passes through the support plate 24 and extends to the outside to be provided with a limiting plate 25, and the top of the movable gear 26 is fixedly connected to the limiting cylinder 27, and the limiting cylinder 27 is slidably connected to the limiting plate 25, and a transmission gear 29 is fixedly connected to the transmission shaft 28, and the movable gear 26 can be meshed with the transmission gear 29 for transmission.

[0064] The telescopic member 35 may be a telescopic cylinder for driving the telescopic rod 36 to move telescopically, so that the telescopic rod 36 drives the mounting plate 44 to move synchronously. When the stirring paddle 21 and the exhaust mechanism need to be started, the starting Figure 8 As shown in , the telescopic member 35 drives the mounting plate 44 to move, so that the limiting cylinder 27 slides from the limiting plate 25 to the bottom, thereby making the movable gear 26 mesh with the transmission gear 29, and the transmission gear 29 will rotate synchronously at this time.

[0065] When the stirring paddle 21 and the exhaust mechanism need to stop, the switch of the telescopic member 35 is started, so that the telescopic rod 36 drives the mounting plate 44 to reset. During this process, the limit cylinder 27 slides from the bottom of the limit plate 25 to the top, thereby stopping the movable gear 26 from meshing with the transmission gear 29.

[0066] During the above process, the transmission rod 18 always keeps rotating. When the movable gear 26 is meshed with the transmission gear 29, the limit plate 25 can limit the limit cylinder 27, and the mounting shaft 37 connected to the mounting plate 44 is rotated to keep the movable gear 26 in a rotating state during the movement. A sliding groove engaged with the limit plate 25 is provided in the limit cylinder 27, so that it can only be in a sliding state.
