Description

Technical Field

[0001] This invention relates to the field of fermented feed and feeding technology, and in particular to a liquid fermentation and liquid feeding method for pickled mustard tuber tails. Background Technology

[0002] The production of pickled mustard tubers generates a large amount of waste. Directly discarding this waste can easily cause environmental pollution and resource waste. Treating it through liquid fermentation and then using it as livestock feed can achieve resource utilization of the waste, reduce breeding costs, and reduce environmental pollution, aligning with the concept of green agriculture. Therefore, combining liquid fermentation with liquid feeding has become the core path for the resource utilization of pickled mustard tuber waste. However, existing methods rely heavily on manual labor or separately driven equipment for loading and unloading, requiring repeated use of containers to transfer materials, resulting in high labor intensity, low efficiency, and potential leakage and contamination during transport. Furthermore, the integration of mixed fermentation and feeding is not smooth, leading to poor mixing and affecting fermentation quality. Loading and feeding are also cumbersome. The equipment is difficult to move, making it hard to flexibly adjust according to the location of the breeding site, storage tanks, and feeding system, further increasing operational difficulty and labor costs. This hinders the promotion and application of liquid fermentation feeding technology for pickled mustard tuber waste, failing to meet the core requirements of "high-efficiency resource utilization, labor-saving convenience, and smooth integration."

[0003] More importantly, the chopped leaves obtained after chopping the pickled mustard tuber (referred to as pickled mustard tuber chopped leaves) need to be mixed with the additives first. During this process, the pickled mustard tuber chopped leaves are very easy to stick to the side wall of the mixing container and can easily block the transfer channel. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing methods, which rely heavily on manual labor or individually driven equipment for loading and unloading, require repeated use of barrels to transfer materials, resulting in high labor intensity, low efficiency, and easy material leakage and contamination during the transfer process; poor coordination between the mixing fermentation and feeding stages, leading to poor mixing effect and affecting fermentation quality; cumbersome loading and feeding transfer; and inconvenient equipment mobility, making it difficult to flexibly adjust according to the location of the breeding site, storage tanks, and feeding system, further increasing the difficulty of operation and labor costs. Therefore, this invention proposes a liquid fermentation and liquid feeding method for pickled mustard tuber tails.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A liquid fermentation device for pickled mustard tuber residue includes a fermentation mechanism and an adjustable feeding and unloading mechanism. The fermentation mechanism includes a mobile vehicle, on which a stirring assembly is installed. A hydraulic control assembly is connected to one side of the stirring assembly. The hydraulic control assembly can operate a bidirectional bevel gear shaft to mesh with the first bevel gear of the mobile vehicle and the second bevel gear of the stirring assembly to realize the transfer operation of the mobile vehicle. The adjustable loading and unloading mechanism includes a conveying component, a discharging component is provided above the conveying component, and the valve structure of the conveying component is connected to the bottom of the mixing tank of the mixing component.

[0006] Preferably, the mobile vehicle includes a base box and two wheels, the wheels being rotatably mounted on the base box via bearings, and a tool box being fixedly connected to the top of the base box.

[0007] Preferably, a worm gear is fixedly installed on the axle of one of the walking wheels, the worm gear meshes with a worm, the worm is rotatably mounted on the base box via a bearing, and a first bevel tooth is installed at the top of the worm.

[0008] Preferably, the mixing assembly includes a mixing tank and a belt drive structure. The mixing tank is fixedly connected to the base box. The mixing tank is equipped with a mixing cage inside. The mixing cage is rotatably mounted below the mixing tank via bearings. The bottom end of the mixing cage is fixedly connected to one of the output shafts of a dual-shaft motor. The dual-shaft motor is mounted on the base box. A second bevel gear is installed on the other output shaft of the dual-shaft motor.

[0009] Preferably, the material conveying assembly includes a material conveying cylinder, which is fixedly connected to the base box. A spiral shaft is provided inside the material conveying cylinder. The bottom end of the spiral shaft is rotatably mounted on the base box through a bearing. The spiral shaft is connected to the output shaft of a dual-axis motor through a belt drive structure.

[0010] Preferably, a plurality of clamps are fixedly connected to the upper part of the feeding cylinder, a feed inlet and a valve structure are provided at the lower part of the feeding cylinder, a guide sleeve is fixedly connected to one side of the feeding cylinder, a baffle is slidably connected inside the guide sleeve, and the baffle is fixed to the feeding cylinder by bolts.

[0011] Preferably, the discharge assembly includes a discharge hopper, which is rotatably mounted above the conveying cylinder via a bearing. The discharge port of the discharge hopper is located above the mixing tank. A fixing member is fixedly connected to one side of the discharge hopper, and a locking bolt is provided on the fixing member. The locking bolt is adapted to the shape of the ferrule.

[0012] Preferably, the hydraulic control assembly includes a bidirectional bevel gear shaft, a handle, and two piston cylinders. The handle is fixedly connected to the mixing tank, and the two piston cylinders are respectively installed below the handle and the mixing tank, and are connected to each other by a pipe.

[0013] Preferably, both piston cylinders are provided with piston rods. A spring is fixedly connected between the upper piston rod and the side wall of the piston cylinder. The upper piston rod extends out of the piston cylinder and is fixedly connected to the operating handle. The lower piston rod extends out of the piston cylinder and is fixedly connected to the bracket. The bidirectional bevel gear shaft is rotatably mounted on the bracket through bearings.

[0014] To better address the issue of pickled mustard tuber scraps easily adhering to the sidewalls of the mixing container and clogging the transfer channel, the mixing cage consists of a mixing shaft, mixing blades, and an L-shaped flexible connecting plate. The L-shaped flexible connecting plate is made of silicone material and is connected to the outer end of the mixing blades. The L-shaped flexible connecting plate can be bent. During device operation, whenever the L-shaped flexible connecting plate is outside the connecting channel, the part of the L-shaped flexible connecting plate that contacts the bottom and side walls of the mixing tank is bent, meaning that the bottom edge of the L-shaped flexible connecting plate is in pressure contact with the bottom and side walls of the mixing tank. Whenever the corner edge of the L-shaped flexible connecting plate passes through the connecting channel, the corner edge of the L-shaped flexible connecting plate (i.e., the corner edge of the L-shaped flexible connecting plate) is inside the connecting channel.

[0015] A method for liquid fermentation and liquid feeding of pickled mustard tuber tails includes the following steps: S1. During the liquid fermentation of pickled mustard tuber tails, the mixing cage is driven to rotate by a dual-shaft motor, and the screw shaft is also driven to rotate by a belt drive structure. The screw shaft conveys the tails and refined materials upward and discharges them into the mixing box through the discharge hopper, so that the mixing cage can carry out the mixing operation. After the material is fed, microbial additives and water are added, and then the baffle is lowered to close the feed port and the valve structure is opened. At this time, the fermentation material is transferred from the mixing box to the conveying cylinder and circulates up and down to accelerate the mixing efficiency. S2. After mixing, remove the locking bolt from the sleeve, rotate the discharge hopper to align with the fermentation tank, and lock it into the sleeve using the locking bolt. At this time, the fermented material is output from the mixing box and discharged into the fermentation tank through the discharge hopper for fermentation. After the feed is discharged, reset the discharge hopper. The fermentation process includes: inoculating with Lactobacillus plantarum and carrying out liquid fermentation at 20℃–35℃. After 2-5 days of fermentation, liquid fermented feed is obtained. S3. After fermentation is complete, the fermented material is fed back into the mixing tank for storage via the screw shaft. Then, pull the operating handle close to the handle to force the piston rod to press the liquid into the lower piston cylinder. This causes the support to drive the bidirectional bevel gear shaft downwards, engaging with the first and second bevel gears. At this time, the second bevel gear drives the worm to rotate, and the worm gear drives the worm wheel. The worm wheel drives the traveling wheel to move, thus smoothly transferring the fermented material to the feeding area of ​​the liquid feeding system. The fermented material is then transported to the liquid feeding system for feeding via the screw shaft and the discharge hopper. Beneficial effects

[0016] The mixing component enables the mixing of fermentation materials. Simultaneously, the mixing component serves as a power source, driving the conveying component to feed the leftover vegetables and concentrates into the mixing component. This facilitates quick and easy feeding and reduces the investment in drive equipment. During the mixing process, the conveying component also enables vertical convection of the fermentation materials in the mixing tank, breaking up the stratification of the fermentation materials and improving the uniformity and efficiency of mixing. After mixing, the discharge component can be used to adjust the discharge direction, allowing the fermentation materials to be directly fed into the fermentation tank for fermentation. After fermentation, the conveying component can be used to remove the materials and transfer them to the liquid feeding system. This achieves a seamless integration of the entire process of feeding, mixing, and fermentation, making the entire process simpler, more convenient, and improving operational efficiency. The bidirectional bevel gear shaft can be adjusted by the hydraulic control component and used as a transmission component for the mixing component and the mobile vehicle. When moving, the power is directly provided by the mixing component's own drive system, achieving a labor-saving effect during the movement process. Operators can flexibly adjust the equipment position according to the location of the fermentation tank, the layout of the feeding system, and the needs of the breeding site to adapt to different operating scenarios. The hydraulic control components enable the mixing components and the mobile vehicle to move automatically, providing a basis for the full-process operation of the multi-functional material conveying components. The equipment posture can be precisely adjusted according to the position of the storage tank and the feeding system, ensuring that the material conveying components and the discharge components can accurately connect with each operation link. The integrated operation mode of the material conveying components and the mixing components reduces the material transfer links, thereby realizing a closed-loop operation of flexible movement, labor-saving feeding, uniform mixing, convenient unloading and efficient feeding, improving operation efficiency and realizing the efficient and convenient utilization of pickled mustard tuber waste. This invention not only solves the problem of pickled mustard tuber leaves adhering to the inner wall of the mixing tank, but also effectively prevents the entire device from clogging. It is conducive to the miniaturization of the entire device, which can be operated by a single person and occupies less than three cubic meters of space. It is especially suitable for small-scale growers to process pickled mustard tuber leaves in the field. Attached Figure Description

The bottom end of the stirring cage 1022 is connected to a dual-shaft motor 1023. One of the output shafts is fixedly connected and drives the mixing cage 1022 to rotate via a dual-shaft motor 1023. The mixing cage 1022 can mix concentrate, vegetable waste, microbial additives and water. During the transfer process, it can also mix the fermented material again to further improve feed quality. The dual-shaft motor 1023 is mounted on the bottom box 1011. A second bevel gear 1024 is mounted on the other output shaft of the dual-shaft motor 1023. A hydraulic control component 103 is connected to one side of the mixing component 102. The adjustable loading and unloading mechanism 200 includes a conveying assembly 201, which includes a conveying cylinder 2011. The conveying cylinder 2011 has an inner diameter of 25cm and is made of stainless steel. The conveying cylinder 2011 is fixedly connected to the base box 1011. A screw shaft 2012 is installed inside the conveying cylinder 2011. The bottom end of the screw shaft 2012 is rotatably mounted on the base box 1011 via a bearing. The screw shaft 2012 is connected to the output shaft of a dual-axis motor 1023 via a belt drive structure 1025. The belt drive structure 1025 enables the power output of the dual-axis motor 1023 to the screw shaft 2012, reducing the need for drive equipment, lowering costs, and making the screw shaft 2012 more efficient. The 012 rotation ensures stable feeding operations, reducing feeding difficulty. Multiple clamps 2016 are fixedly connected to the top of the feeding cylinder 2011. A feed inlet and valve structure 2015 are located below the feeding cylinder 2011. The valve structure 2015 includes a connecting channel 2017 for connecting the inner cavity of the mixing tank 1021 and the feeding cylinder 2011, and a valve installed on the connecting channel 2017. The inner diameter of the connecting channel 2017 is 25cm. The feed inlet facilitates the feeding of leftover vegetables and refined materials, simplifying the conveying operation of the screw shaft 2012. When the valve structure 2015 is open, it ensures that the fermented material undergoes a bottom-up flowing mixing operation, improving mixing efficiency. A guide sleeve 2014 is fixedly connected to one side of the feed cylinder 2011. A baffle 2013 is slidably connected inside the guide sleeve 2014. The baffle 2013 is fixed to the feed cylinder 2011 by bolts. The feed inlet is closed by the lower baffle 2013, and the lower part of the feed cylinder 2011 is in a closed state, which facilitates the conveying of fermentation material from the mixing tank 1021. The bolts can also fix the position of the baffle 2013 to prevent the baffle 2013 from loosening and affecting the feeding of the feed inlet. A discharge assembly 202 is provided above the feed assembly 201. The discharge assembly 202 includes a discharge hopper 2021. The discharge hopper 2021 is rotatably mounted above the feed cylinder 2011 by bearings. The discharge port of 021 is located above the mixing tank 1021. The discharge hopper 2021 can be rotated and adjusted to adjust the feeding position, which is convenient for feeding operations at different positions according to the needs of the site. A fixing member 2022 is fixedly connected to one side of the discharge hopper 2021. The fixing member 2022 is equipped with a locking bolt 2023. The position of the discharge hopper 2021 can be fixed by inserting the locking bolt 2023 into the sleeve 2016 to ensure the stability of the discharge hopper 2021. The locking bolt 2023 and the sleeve 2016 are compatible in shape. The valve structure 2015 of the conveying component 201 is connected to the lower part of the mixing tank 1021 of the mixing component 102.

[0021] In this embodiment: the stirring component 102 is used to stir the fermentation material. At the same time, the stirring is used as a power source to drive the conveying component 201 to put the leftover vegetables and concentrates into the stirring component 102, which facilitates quick feeding and reduces the investment in driving equipment. During the stirring process, the valve structure 2015 connects the stirring tank 1021 and the conveying component 201. The conveying component 201 can also realize the vertical convection of the fermentation material in the stirring tank 1021, break the layering of the fermentation material, and improve the uniformity and efficiency of mixing. After the stirring is completed, the discharge component 202 can be used to adjust the discharge direction, and the fermentation material can be directly put into the fermentation tank for fermentation. After fermentation, the conveying component 201 can be used to take it out and put it into the liquid feeding system, realizing the integrated connection of the entire process of feeding, mixing and fermentation feeding, and improving the work efficiency.

[0022] Example 2: Based on Example 1, further referencing Figures 5-8 A liquid fermentation device for pickled mustard tuber waste includes a mobile cart 101, which comprises a base box 1011 and two wheels 1012. The wheels 1012 are rotatably mounted on the base box 1011 via bearings. A tool box 104 is fixedly connected to the top of the base box 1011, serving as a storage container for tools. A worm gear 1013 is fixedly mounted on the axle of one of the wheels 1012. The worm gear 1013 meshes with a worm 1014, and the worm gear 1014 drives the worm wheel 1012, thus providing power to the wheel 1012. This facilitates the movement of the device and reduces the workload. The worm 1014 is rotatably mounted on the base box 1011 via bearings. The top of the 4 is equipped with a first bevel gear 1015. A worm gear 1013 is fixedly installed on the axle of one of the traveling wheels 1012. The worm gear 1013 meshes with the worm 1014. The worm 1014 is rotatably mounted on the base box 1011 through a bearing. The top of the worm 1014 is equipped with a first bevel gear 1015. The hydraulic control component 103 can operate the bidirectional bevel gear shaft 1038 to mesh with the first bevel gear 1015 of the mobile vehicle 101 and the second bevel gear 1024 of the mixing component 102 to realize the transfer operation of the mobile vehicle 101. By meshing the bidirectional bevel gear shaft 1038 with the first bevel gear 1015 and the second bevel gear 1024, the transmission components of the traveling wheel 1012 can be moved, thereby reducing the waste of power source. The hydraulic control assembly 103 includes a double-bevel gear shaft 1038, a handle 1031, and two piston cylinders 1032. The handle 1031 is fixedly connected to the mixing tank 1021. The two piston cylinders 1032 are respectively installed below the handle 1031 and the mixing tank 1021, and are connected to each other by a pipe 1036. Each piston cylinder 1032 is provided with a piston rod 1034. A spring 1033 is fixedly connected between the upper piston rod 1034 and the side wall of the piston cylinder 1032. By releasing the operating handle 1035, the spring 1033 can drive the piston. Rod 1034 resets, allowing the liquid to flow upwards, thereby disengaging the bidirectional bevel gear shaft 1038 from the first bevel gear 1015 and the second bevel gear 1024. The upper piston rod 1034 extends out of the piston cylinder 1032 and is fixedly connected to the operating handle 1035. By pulling the operating handle 1035 to engage with the handle 1031, the moving vehicle 101 can be directly operated, facilitating control operations. The lower piston rod 1034 extends out of the piston cylinder 1032 and is fixedly connected to the bracket 1037. The bidirectional bevel gear shaft 1038 is rotatably mounted on the bracket 1037 via bearings.

[0023] In this embodiment: by pulling the operating handle 1035 close to the handle 1031, the piston rod 1034 outputs liquid to the piston cylinder 1032 below. At this time, the hydraulically controlled support 1037 moves downward. At this time, the bidirectional bevel gear shaft 1038 meshes downward with the first bevel gear 1015 and the second bevel gear 1024, which can be used as a transmission component for the stirring assembly 102 and the moving vehicle 101. When moving, the stirring assembly 102 directly uses its own drive system to provide power, achieving a labor-saving effect during the movement. The operator can flexibly adjust the position of the equipment according to the location of the fermentation tank, the layout of the feeding system, and the needs of the breeding site to adapt to different operating scenarios.

[0024] Example 3: Based on Example 2, further referencing Figures 1-3 and Figure 7 A liquid fermentation device for pickled mustard tuber tails includes a fermentation mechanism 100, an adjustable loading and unloading mechanism 200 mounted on the fermentation mechanism 100, a moving cart 101, a stirring assembly 102 mounted on the moving cart 101, and a hydraulic control assembly 103 connected to one side of the stirring assembly 102. The hydraulic control assembly 103 can operate a bidirectional bevel gear shaft 1038 to mesh with the first bevel gear 1015 of the moving cart 101 and the second bevel gear 1024 of the stirring assembly 102, thereby realizing the transfer operation of the moving cart 101. The adjustable loading and unloading mechanism 200 includes a conveying component 201, a discharge component 202 is provided above the conveying component 201, and the valve structure 2015 of the conveying component 201 is connected to the lower part of the mixing tank 1021 of the mixing component 102.

[0025] In this embodiment, the hydraulic control component 103 enables the mixing component 102 and the moving vehicle 101 to move automatically, providing a basis for the full-process operation of the multi-functional material conveying component 201. The device posture can be precisely adjusted according to the position of the storage tank and the feeding system, ensuring that the material conveying component 201 and the discharge component 202 can accurately connect to each operation link. The integrated operation mode of the material conveying component 201 and the mixing component 102 reduces the material transfer links, thereby realizing a closed-loop operation of flexible movement, labor-saving feeding, uniform mixing, convenient unloading and efficient feeding, improving operation efficiency and realizing the efficient and convenient utilization of pickled mustard tuber waste resources.

[0026] In this embodiment, combined with Figure 9 and Figure 10 As shown, the mixing cage 1022 consists of a mixing shaft, mixing blades, and an L-shaped flexible connecting plate 1026. The L-shaped flexible connecting plate 1026 is made of silicone material and is connected to the outer end of the mixing blades. The L-shaped flexible connecting plate 1026 can be bent. During operation, whenever the L-shaped flexible connecting plate 1026 is outside the connecting channel 2017, the part of the L-shaped flexible connecting plate 1026 in contact with the bottom wall 1020 and side wall of the mixing tank is shaped like... Figure 9 The bending state shown indicates that the corner edge 1027 of the L-shaped flexible connecting plate is in pressure contact with the bottom wall 1020 and side wall of the mixing tank. Whenever the corner edge 1027 of the L-shaped flexible connecting plate passes through the connecting channel 2017, the corner edge of the L-shaped flexible connecting plate 1026 (i.e., the corner edge 1027 of the L-shaped flexible connecting plate is located within the connecting channel 2017) is as follows: Figure 10 As shown in the diagram. This structure not only solves the problem of pickled mustard tuber leaves adhering to the inner wall of the mixing tank, but also effectively prevents material blockage in the entire device, which is conducive to the miniaturization of the entire device.

[0027] Example 4: A method for liquid fermentation and liquid feeding of pickled mustard tuber tails, using the apparatus in Example 3, comprising the following steps: S1. Before the liquid fermentation of pickled mustard tuber tails, crushed pickled mustard tuber tails are added from the feed inlet. The mixing cage 1022 is driven to rotate by the dual-shaft motor 1023, and the spiral shaft 2012 is driven to rotate by the belt drive structure 1025. The spiral shaft 2012 conveys the tails and refined materials upward and discharges them into the mixing box 1021 through the discharge hopper 2021, so that the mixing cage 1022 can carry out the mixing operation. After the feeding is completed, microbial additives and water are added, and then the baffle 2013 is lowered to close the feed inlet and the valve structure 2015 is opened. At this time, the fermentation material is transferred from the mixing box 1021 to the conveying cylinder 2011 and circulates up and down to accelerate the mixing efficiency. S2. After mixing, remove the locking bolt 2023 from the sleeve 2016, then rotate the discharge hopper 2021 to align with the fermentation tank, and lock it into the sleeve 2016 using the locking bolt 2023. At this time, the fermented material is output from the mixing box 1021 and discharged into the fermentation tank through the discharge hopper 2021 for fermentation. After the feed is discharged, reset the discharge hopper 2021. The fermentation process includes: inoculating Lactiplantibacillus plantarum (preservation number: GDMCC No: 65791, preservation date: January 15, 2025, classification name: Lactiplantibacillus plantarum, preservation unit: Guangdong Provincial Center for Microbial Culture Collection, preservation unit address: Institute of Microbiology, Guangdong Academy of Sciences, 5th Floor, Building 59, No. 100 Xianlie Middle Road, Guangzhou) at an inoculation rate of 0.5% (V / W), and carrying out liquid fermentation at a constant temperature of 25℃. After 5 days of fermentation, liquid fermented feed is obtained. The steps for obtaining Lactobacillus plantarum B3 are described in the instruction manual CN121343830A. S3. After fermentation is complete, the fermented material is again fed into the mixing tank 1021 for storage via the screw shaft 2012. Then, the operating handle 1035 is pulled close to the handle 1031, causing the piston rod 1034 to deform the spring 1033 and press the liquid into the lower piston cylinder 1032. This causes the bracket 1037 to drive the double-sided bevel gear shaft 1038 downwards, engaging with the first bevel gear 1015 and the second bevel gear 1024. At this time, the second bevel gear 1024 drives the worm gear 1014 to rotate. The worm gear 1014 drives the worm wheel 1013, which in turn drives the walking wheel 1012 to move, smoothly transferring the fermented material to the feeding area of ​​the liquid feeding system. At this time, the operating handle 1035 is released, and the spring 1033 drives the piston rod 1034 to reset, causing the liquid to flow back upward. The bidirectional bevel gear shaft 1038 separates from the first bevel gear 1015 and the second bevel gear 1024, and then the fermented material is transported to the liquid feeding system for feeding through the screw shaft 2012 and the discharge hopper 2021.

[0028] Comparative Example: One stainless steel mixing tank with an inner diameter of 1m and one fermentation tank with an inner diameter of 1.5m are used. The mixing tank and the fermentation tank are connected by a negative pressure pipe with an inner diameter of 25cm. The entire system occupies approximately six cubic meters of space. In use, the additives and crushed pickled mustard greens are first loaded into the mixing tank and stirred. Then, the negative pressure adsorption system is turned on to adsorb the material in the mixing tank into the fermentation tank for fermentation.

[0029] Using the methods in Examples 3 and 4, no equipment blockage occurred during the continuous processing of two tons of vegetable scraps. After the material in the mixing tank was directly discharged, almost no residual material was visible on the inner and bottom walls of the mixing tank (less than 20g of residual material). However, using the traditional method in the comparative examples, a negative pressure pipe blockage occurred when processing two hundred kilograms of vegetable scraps. After the material in the mixing tank was discharged, approximately two kilograms of residual material was visible adhering to the inner and bottom walls of the mixing tank.
