Description

Technical Field

[0001] The invention relates to feed production and processing equipment in the technical field of animal husbandry, and in particular to equipment and a method for preparing a complete mixed ration fermentation bag. Background Art

[0002] Total mixed ration, referred to as TMR, refers to a ration with different nutrients prepared on demand according to the nutritional needs of animals at different growth and development and lactation stages. The ingredients (silage, concentrate feed, minerals, vitamins, etc.) are evenly mixed together through a mixing device according to the proportion, so as to prepare feed that meets the needs of the animal stage. FTMR refers to fermented total mixed ration, a new type of feed product that combines the advantages of total mixed ration (TMR) and fermentation technology. TMR is anaerobically fermented under anaerobic conditions using lactic acid bacteria and other composite bacteria to convert substances in the feed into organic acids such as lactic acid, reduce the pH value of the feed, inhibit the growth of harmful microorganisms, and produce some beneficial metabolites, thereby improving the quality and nutritional value of the feed. After fermentation, FTMR will produce a unique fermentation aroma, which can significantly increase the feed intake rate and regulate the balance of animal intestinal microecology.

[0003] The preparation of the existing fermented complete mixed diet requires the materials to be crushed, stirred, sterilized at high temperature, and added with composite bacteria. The existing preparation equipment has a low degree of mechanization. For example, the equipment disclosed in the invention patent of CN 115336773 A can only perform the functions of crushing, inoculating and mixing. The materials after adding bacteria are directly discharged for subsequent fermentation. The subsequent dispersed materials still need to be manually loaded into sealed bags for later anaerobic fermentation.

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] In the following description, with reference to the accompanying drawings, several embodiments of the present application are described. It should be understood that other embodiments may also be used, and mechanical composition, structure, electrical and operational changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description should not be considered restrictive, and the scope of the embodiments of the present application is limited only by the claims of the published patents. The terms used here are only to describe specific embodiments and are not intended to limit the present application. Spatially related terms, such as "upper", "lower", "left", "right", "below", "below", "lower", "above", "upper", etc., may be used in the text to facilitate the description of the relationship between an element or feature shown in the figure and another element or feature.

[0041] See attached Figure 1 , 9As shown, a complete mixed diet fermentation bag preparation equipment includes a material crushing and mixing all-in-one machine 1, a conveyor line 3, a material processor 6 and a dispensing module 17; the material crushing and mixing all-in-one machine 1 is mainly used to crush and mix silage and concentrate. Through the design of the all-in-one machine, the raw materials can be quickly crushed and evenly mixed, which reduces the time of dispersion, mixing and crushing in traditional processes and significantly improves work efficiency. The equipment includes a first discharge port 2, through which the crushed and mixed materials are conveyed to the downstream conveyor line 3; the conveyor line 3 is located below the first discharge port 2 of the material crushing and mixing all-in-one machine 1, and is used to transfer materials from the all-in-one machine to the material processor 6. A hopper 4 is provided at one end of the conveyor line 3, and a second discharge port 5 is obliquely arranged below the hopper 4 to feed the material into the extrusion chamber 8 of the material processor 6.

[0042] Combined with Figure 2 , 3 As shown in , 4, the material processing machine 6 is a key part of the entire fermentation bag preparation equipment, which is responsible for compressing the material and forming the fermentation bag. The material processing machine 6 includes a frame 7, an extrusion chamber 8, a discharge base 9, a pressure plate 10, a distribution block 11 and a driving mechanism 12; the frame 7 is the main supporting structure of the material processing machine 6 and plays a supporting role. The extrusion chamber 8, the discharge base 9, the pressure plate 10, the distribution block 11 and the driving mechanism 12 are all installed on the frame 7. In the spatial distribution of the frame 7, from top to bottom are the distribution block 11, the pressure plate 10, the extrusion chamber 8 and the discharge base 9, and these components work together to process the material.

[0043] Specifically, the extrusion chamber 8 is located on the side of the second discharge port 5 of the material processing machine 6. Its internal structure is a hollow design with openings at the top and bottom. This design facilitates material input and discharge. The top and bottom openings allow the material to flow smoothly into and out of the extrusion chamber 8, avoiding work interruptions caused by blockage. The shape and design of the extrusion chamber 8 enable it to adapt to materials of different types and specifications, ensuring the compression effect and uniformity of the complete mixed ration, thereby improving production efficiency and product quality.

[0044] The unloading base 9 is arranged at the bottom opening of the extrusion chamber 8 and is movable. Its main function is to ensure that the material can be discharged from the extrusion chamber 8 smoothly after extrusion, so as to avoid the subsequent operation being affected by the material being stuck or unevenly compressed. The movable design of the material base can be adjusted with the change of the pressure in the extrusion chamber 8, so as to ensure that the material can be discharged smoothly from the extrusion chamber 8 during the processing. At the same time, this movable design can also help avoid the backlog of materials, thereby improving production efficiency. The movement of the unloading base 9 can also be automatically completed by the drive system, reducing manual intervention, so that the overall automation level of the equipment can be improved. The specific drive thereof will be comprehensively described later.

[0045] The pressing plate 10 is located at the top opening of the extrusion chamber 8. It moves up and down under the control of the driving mechanism 12 to compress the material. The up and down movement of the pressing plate 10 is achieved by the drive of the first driving component 15. When the pressing plate 10 is pressed down, the material is well compressed under the action of uniform pressure, thereby ensuring the stability of the fermentation effect.

[0046] The dispensing block 11 is located above the pressing plate 10 and is designed with multiple injection rods 13. The injection rods 13 can movably pass vertically through the pressing plate 10 and include an interface 14 arranged on the top of the dispensing block 11. The function of the dispensing block 11 is to accurately inject additives into the material and control the gas flow during the compression process. The injection rod 13 is designed to be needle-shaped, which can accurately penetrate the material and inject high-temperature steam, nitrogen source or fermentation additives (compound lactic acid bacteria, enzyme preparations, probiotics, acidulants, minerals, etc.). The injection of these gases and additives helps to provide necessary humidity conditions or specific chemical components during the fermentation process of the material, thereby promoting the smooth progress of fermentation. The active design of the injection rod 13 can ensure the uniform distribution of gas and additives and avoid local excess or deficiency.

[0047] The distribution block 11 is a key component of the present invention, and its design purpose is to accurately control the production process of the total mixed diet fermentation bag to ensure the accurate injection of additives and the uniform compression of materials. Through a series of carefully designed structural components, the distribution block 11 can not only operate stably under high pressure environment, but also flexibly respond to different production needs, thereby improving the production efficiency and product quality of the fermentation bag.

[0048] Among them, combined with Figure 2 , 3 As shown in Figures 4 and 5, the driving mechanism 12 includes a first driving component 15, a second driving component 16 and a third driving component 26. The first driving component 15 drives the pressure plate 10 to move in the extrusion chamber 8 in the form of an up and down piston movement. The second driving component 16 drives the dispensing pressure block 11 to move up and down outside the upper opening of the extrusion chamber 8. The third driving component 26 is respectively arranged on both sides of the discharge base 9 to drive the flipping movement of the discharge base 9.

[0049] Specifically, a second drive assembly 16 is installed on the top of the frame 7, and the second drive assembly 16 includes a pair of telescopic cylinders 29, and the telescopic ends of the telescopic cylinders 29 are fixedly connected to the upper end of the dispensing block 11, while the first drive assembly 15 is installed on the dispensing block 11, and the first drive assembly 15 also includes a telescopic cylinder 29, and the telescopic end of the telescopic cylinder 29 of the first drive assembly 15 is fixedly connected to the pressure plate 10.

[0050] Furthermore, if Figure 3As shown, the dispensing block 11 is mainly composed of the following parts: a bottom plate 19, a protective edge strip 20 and a trapezoidal side plate 21; the bottom plate 19 is located at the bottom of the dispensing block 11 to provide overall support, the protective edge strip 20 and the trapezoidal side plate 21 are fixedly connected to ensure the stability of the structure, and the trapezoidal side plate 21 provides additional support for the dispensing block 11 to ensure that it does not tilt or deform during operation; the injection rods 13 are evenly arranged on the inner side of the dispensing block 11, and the lower end of each injection rod 13 is designed to have a tip that can smoothly penetrate the material. The injection rod 13 is provided with an interface 14 at the top of the dispensing block 11 to inject the required high-temperature steam, nitrogen or fermentation additives. The uniform distribution of the injection rods 13 ensures the uniform injection of the additives and avoids differences in fermentation effects due to uneven materials. The fixed platform 22 is located above the bottom plate 19 and is fixedly connected to the telescopic cylinder 29 of the second drive assembly 16, ensuring the stability of the dispensing block 11 and the accuracy of movement. The design of the fixed platform 22 enables the dispensing block 11 to move up and down smoothly, thereby adjusting the injection depth and material of the injection rod 13. The upper end of the fixed platform 22 is fixed to the telescopic end of the telescopic cylinder 29 of the second drive assembly 16; and the crossbeam 23 is connected between the two trapezoidal side plates 21, and provides an installation position for the four-way valve 18. The four-way valve 18 is connected to the high-temperature steam source, nitrogen source and fermentation additive source through pipelines, respectively, and can accurately control the injection amount and injection timing of these additives to ensure the accurate distribution of gas or additives during the fermentation process. The design of the bottom plate 19, the trapezoidal side plate 21, the protective edge strip 20 and other structures ensures that the dispensing block 11 has sufficient stability during operation and prevents possible loosening, vibration or tilting.

[0051] A bracket 24 is also provided on the crossbeam 23, and the bracket 24 is used to install the first drive assembly 15. The first drive assembly 15 is fixed on the distribution block 11 through the bracket 24. Two slide rods 25 are also connected to the telescopic end of the telescopic cylinder 29 of the first drive assembly 15 through an adapter plate. The slide rod 25 passes through the bottom plate 19 through the sliding opening on the bottom plate 19 and is fixedly connected to the upper end of the pressing plate 10, ensuring the stability and smooth movement of the pressing plate 10 during the material processing process. The first drive assembly 15 drives the slide rod 25 and the pressing plate 10 to move up and down through the telescopic cylinder 29 to achieve compression of the material. The design of the four-way valve 18 provides flexibility, and can flexibly switch different additives or gases according to production needs to adapt to different types of materials and fermentation requirements. The first drive assembly 15 and the second drive assembly 16 both cooperate with the telescopic cylinder 29 to enable the distribution block 11 and the pressing plate 10 to move up and down accurately in the extrusion chamber 8, thereby ensuring uniform compression of the material and accurate delivery of the additive, as well as precise compression of the material.

[0052] Furthermore, if Figure 5 , 6As shown, the third driving assembly 26 of the driving mechanism 12 is mainly used for the flipping activity of the unloading base 9. The third driving assembly 26 is fixed on the frame 7. At the same time, a corresponding third driving assembly 26 is provided on both sides of the unloading base 9. The third driving assembly 26 includes a lever 27, a connecting rod 28 and a telescopic cylinder 29. The telescopic cylinder 29 is an actuator that can provide a power source for the movement of the unloading base 9. A support rod 32 is provided at one end of the unloading base 9. The support rod 32 is rotatably connected to the frame 7, and the telescopic end of the telescopic cylinder 29 is hinged to the middle part of the lever 27. One end of the lever 27 is hinged to the upper end of the connecting rod 28. The other end of the lever 27 is provided with a rotating shaft 30. The rotating shaft 30 is movably connected to the frame 7, and the lower end of the connecting rod 28 is hinged to one side of the unloading base 9; One end is rotatably connected to the frame 7, and the third driving assembly 26 drives the hinged end position of the unloading base 9 and the connecting rod 28 to realize the flipping of the unloading base 9 with the rotating connection end of the frame 7 as the axis. An axle seat 36 is provided on the frame 7, and a connecting shaft 37 is provided in the axle seat 36. The two ends of the connecting shaft 37 are respectively connected to the rotating shaft 30 of each shift rod 27. When the telescopic cylinder 29 is actuated, the shift rod 27 is pushed to rotate with the rotating shaft 30 as the axis, and the connecting rod 28 is driven to move at the same time. The connecting rod 28 and the shift rod 27 form a connecting rod 28 mechanism. The connecting rod 28 mechanism generates a pushing force on the unloading base 9, so that the unloading base 9 rotates with the support rod 32 as the axis, and the unloading base 9 is flipped downward. By flipping down the unloading base 9, the material block can be released from the bottom of the extrusion chamber 8 for the subsequent wrapping step.

[0053] like Figure 7 , 8 As shown, in a further optimized embodiment, a vertically arranged guide groove 31 is further provided on the frame 7, and a support rod 32 is provided at one end of the unloading base 9, the support rod 32 is slidably arranged in the guide groove 31, and the support rod 32 is a circular rod body so as to rotate with the frame 7, and a slide groove 35 arranged along its length direction is also provided on the side of the connecting rod 28. At the same time, the third driving assembly 26 also includes a limiting rod 33, one end of the limiting rod 33 is hingedly connected to one side of the unloading base 9 (the same side as the support rod 32), and the other end of the limiting rod 33 is slidably arranged in the slide groove 35 through a slider 34, and the slider 34 and the limiting rod 33 are both hinged. By adding the setting of the limiting rod 33 and the guide groove 31, the unloading base 9 can be driven to move downward synchronously when it is flipped downward, so that the unloading base 9 is flipped into an inclined state and also moves downward, which is convenient for the block-shaped materials to slide out. Such a setting makes the separation of the material blocks smoother. Moreover, when driving the unloading base 9 to return upward, the cooperation of the limit rod 33 and the slider 34 can limit the running trajectory of the unloading base 9, ensuring that the unloading base 9 can correctly ascend to the bottom of the extrusion chamber 8 and remain horizontal, which is convenient for the subsequent material compression process.

[0054] Furthermore, an assembly line can be arranged below the unloading base 9 according to actual needs, so that the compressed block materials can be transported to the wrapping machine for rapid wrapping of the block-shaped fermentation bags.

[0055] Based on the above structure, Fig.10 As shown, the present invention further proposes a method for preparing a complete mixed diet fermentation package, which comprises the following steps:

[0056] Step 1: The material crushing and mixing integrated machine 1 mixes the silage and the concentrate according to the proportion, and conveys the mixed materials to the hopper 4;

[0057] Step 2: quantitatively convey the mixed material to the extrusion chamber 8 of the material processing machine 6 through the hopper 4, and keep the discharge base 9 and the extrusion chamber 8 closed;

[0058] Step 3: Start the second driving assembly 16 to drive the dispensing block 11 to move downward, so that the injection rod 13 is inserted into the loose material, and the high-temperature steam source is introduced in sequence to remove bacteria and increase the humidity of the material, nitrogen is introduced to cool the material and remove oxygen from the material, and fermentation additives are injected in proportion;

[0059] Step 4: Start the first driving assembly 15 to drive the pressing plate 10 to move downward into the extrusion chamber 8 to compress the material so that the material is compressed into blocks;

[0060] Step 5: Start the third driving assembly 26 to drive the unloading base 9 to flip, and synchronously cooperate with the pressing plate 10 to press down to discharge the compressed block material out of the extrusion chamber 8. During the process of driving the unloading base 9 to flip, it moves downward synchronously, and the unloading base 9 forms an inclined shape to facilitate the block material to slide out;

[0061] Step 6: Wrap the block material and store it for anaerobic fermentation.

[0062] The fully mixed diet fermentation bag preparation equipment proposed by the present invention uses the material crushing and mixing integrated machine 1, the conveying line 3, the material processing machine 6 and the dispensing module 17 to cooperate with each other, and the material after being mixed by the material crushing and mixing integrated machine 1 is sent to the material processing machine 6 for subsequent processing; during processing, the pressing plate 10 is first kept at the uppermost position, and the cooperation of the material processing machine 6 and the dispensing module 17 can first perform high-temperature sterilization on the material sent to the material processing machine 6 to ensure the high efficiency of the material in the subsequent anaerobic fermentation process, and then introduce low-temperature nitrogen into the material to quickly reduce the material temperature, and at the same time discharge the oxygen in the material, providing a An anaerobic environment is created, and fermentation additives are injected after it is detected that the moisture content and temperature in the material meet the standards. The fermentation additives are injected by a plurality of injection rods 13 to ensure the uniformity of the fermentation additives, and the stirring step can be omitted. After these three steps, the material forms a fermentation environment, and then the pressing plate 10 is driven to press down, and the injection rod 13 gradually leaves the material during the pressing process to avoid the formation of gaps, and the injection rod 13 also provides a guiding function, making the movement of the pressing plate 10 more accurate; the pressing plate 10 moves downward to squeeze the material to form a fermentation bag, and the compressed fermentation bag is wrapped and then left for fermentation.

[0063] Compared with the existing technology, the present invention has the following advantages:

[0064] 1. The present invention combines these operations into a continuous system through the cooperation of the material crushing and mixing integrated machine 1 and the material processing machine 6, which not only saves equipment procurement and installation costs, but also reduces the labor intensity and error rate of operators.

[0065] 2. High-temperature steam, nitrogen and fermentation additives are accurately injected into the material through the injection rod 13 on the dispensing block 11, ensuring the uniform distribution and accurate injection of the additives. Accurate control of additives not only ensures the efficient fermentation, but also improves the microbial fermentation quality of the material and reduces waste. Moreover, by using the precise injection of high-temperature steam source, nitrogen source and fermentation additives, the temperature, humidity and gas composition can be adjusted according to the properties of the material and the fermentation requirements. This controllable fermentation environment helps to enhance the activity of microorganisms and promote the smooth progress of the anaerobic fermentation process.

[0066] 3. The automation method of the present invention can reduce the intervention of manual operation and improve production efficiency. The processed materials are compressed into blocks and then made into fermentation bags for storage for anaerobic fermentation. Compared with the direct fermentation of traditional bulk materials, the use of fermentation bags can effectively save storage space, especially in large-scale production, which can improve storage and transportation efficiency. The compressed materials have a reduced surface area, which is conducive to maintaining uniform distribution of heat and gas during the fermentation process, reducing the risk of uneven fermentation caused by local excessively high or low temperatures. The fermentation bags can better maintain the anaerobic environment of the materials, improve the fermentation efficiency of microorganisms, shorten the fermentation cycle, and improve the quality and stability of the products. The materials made into fermentation bags are more convenient in subsequent processing and management, and are easy to perform quality control, monitoring and batch traceability.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
