Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and in particular to a microbial inoculation device for feed production. Background Technology

[0002] Feed production is the process of scientifically formulating and processing various raw materials (such as grains, protein sources, minerals, vitamins, etc.) into nutritionally balanced, palatable, and easily digestible animal feed. Driven by modern green farming and healthy animal husbandry, microbial strains, as an important type of functional feed additive, are widely used in feed production. These strains can not only improve the intestinal microecology of animals and enhance immunity, but also increase feed conversion rates and reduce antibiotic use, thereby significantly improving feed quality and farming efficiency.

[0003] Existing microbial inoculum addition devices (such as the biological inoculum addition device for compound microbial feed disclosed in Chinese Utility Model Patent CN202021746588.2) have obvious defects in practical applications: Although the device has a preliminary stirring function, after the main material is stirred, an external microbial inoculum addition device still needs to be connected to add the inoculum, which is cumbersome and time-consuming. At the same time, since the inoculum is added after the main material is stirred, there is no synchronous mixing mechanism, which can easily lead to uneven distribution of inoculum, excessively high or low local concentrations, seriously affecting the consistency between feed batches and the activity of inoculum. Utility Model Content

[0004] The purpose of this invention is to provide a microbial inoculation device for feed production, which solves the problem that although the existing technology has a preliminary mixing function, it still requires an external microbial inoculation device to be connected after the main material is mixed in order to add the microbial inoculation, resulting in a cumbersome and time-consuming operation process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A microbial inoculum addition device for feed production includes a mixing tank and a support frame. The mixing tank is connected to one side of the support frame via several mounting brackets. A mounting plate is provided on the top of the mixing tank. One bottom side of the mounting plate is connected to the support frame via a vertical lifting structure, and the other bottom side is connected to a stirring structure that cooperates with the interior of the mixing tank via a driving structure. A spray ring is provided at the top edge of the mixing tank. Several spray pipes penetrating the top of the mixing tank are connected to the bottom of the spray ring. A microbial inoculum storage tank is connected to one side of the support frame via a support plate. A delivery pump is connected to the bottom of the support plate. The input end of the delivery pump is connected to the microbial inoculum storage tank, and the output end is connected to the spray ring via a connecting pipe.

[0006] Preferably, the mounting frame includes a mounting ring and a fixing frame. The mounting ring is fixedly connected to the outer ring of the mixing tank by bolts, and one side of the fixing frame is connected to the side wall of the mounting frame, while the other side is connected to the side wall of the support frame.

[0007] Preferably, the drive structure includes a drive motor mounted on the top of the mounting plate, and the stirring structure includes a rotating rod disposed inside the mixing tank and a plurality of stirring rods connected to the outer ring of the rotating rod, wherein the output shaft of the drive motor is connected to the end of the rotating rod.

[0008] Preferably, support rods are inclinedly provided on both sides of the bottom of the support plate, with one end of the support rod connected to the bottom of the support plate and the other end connected to the side wall of the support frame.

[0009] Preferably, the support frame has sliding grooves on both sides, and the bottom sides of the mounting plate are fixedly connected with sliding rods that slide in cooperation with the sliding grooves. The vertical lifting structure includes a lifting cylinder connected to the bottom of one side of the support frame through a side plate. The output end of the lifting cylinder is connected to a lifting plate, and the two ends of the lifting plate are respectively connected to two sliding rods.

[0010] Preferably, the slide bar is made of metal, and the length of the slide bar is greater than the length of the sliding groove.

[0011] This utility model has the following beneficial effects: This device simultaneously sprays bacterial solution into the mixing tank through spray pipes while the main material is being mixed, ensuring full contact between the bacteria and the main material during dynamic mixing. This effectively prevents localized high or low concentrations, significantly improving distribution uniformity and batch consistency. The spray ring design, combined with multiple spray pipes, ensures that the bacterial solution covers the material from multiple angles, further enhancing the mixing effect. Furthermore, the entire addition process is conducted in a closed environment, reducing the time the bacteria are exposed to air and helping to maintain their activity and stability. The support frame, mounting frame, and support plate form a robust support system, ensuring long-term operational reliability. The vertical lifting structure facilitates adjustment and maintenance of the mixing structure, improving operational flexibility. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Example 1 Please see Figure 1-5 As shown, a microbial inoculum addition device for feed production in this embodiment includes a mixing tank 1 and a support frame 4. The mixing tank 1 is connected to one side of the support frame 4 by several mounting brackets 10. A mounting plate 3 is provided on the top of the mixing tank 1. One bottom side of the mounting plate 3 is connected to the support frame 4 by a vertical lifting structure, and the other bottom side is connected to a stirring structure that cooperates with the inside of the mixing tank 1 by a driving structure. A spraying ring 5 is provided at the top edge of the mixing tank 1. Several spraying pipes 8 that penetrate the top of the mixing tank 1 are connected to the bottom of the spraying ring 5. A microbial inoculum storage tank 6 is connected to one side of the top of the support frame 4 by a support plate 7. A delivery pump 9 is connected to the bottom of the support plate 7. The input end of the delivery pump 9 is connected to the microbial inoculum storage tank 6, and the output end is connected to the spraying ring 5 by a connecting pipe.

[0017] The workflow is as follows: First, the main ingredients, such as grains and protein sources, are added to the mixing tank 1. The mixing tank 1 is fixedly connected to one side of the support frame 4 by several mounting brackets 10 to ensure the stability of the overall structure. Then, the drive structure is activated to drive the stirring structure to perform preliminary mixing of the main ingredients. This stirring structure is driven by the drive mechanism on the other side of the bottom of the mounting plate 3 and extends into the mixing tank 1 to rotate and stir. At the same time, the active microbial liquid stored in the inoculum storage tank 6 is drawn out by the transfer pump 9, which is installed at the bottom of the support plate 7, and its input end is connected to the inoculum storage tank. The output end is connected to the spray ring 5 via a connecting pipe. During the mixing process, the delivery pump 9 pumps the bacterial solution to the spray ring 5, and then sprays it evenly onto the surface of the main material being mixed through multiple spray pipes 8 that penetrate the top of the mixing tank 1. The spray ring 5 is arranged around the top edge of the mixing tank 1 to ensure that the bacterial solution covers the material synchronously and evenly from multiple points. The mounting plate 3 is connected to the support frame 4 through a vertical lifting structure, which can adjust the insertion depth of the mixing structure or facilitate maintenance when needed. The entire addition and mixing process is completed synchronously in the sealed mixing tank 1 without the need for intermediate shutdown or external equipment.

[0018] Example 2 Please see Figure 1-5 As shown in this embodiment, a microbial inoculum addition device for feed production includes a mounting frame 10 comprising a mounting ring and a fixing frame. The mounting ring is fixedly connected to the outer ring bolt of the mixing tank 1. One side of the fixing frame is connected to the side wall of the mounting frame 10, and the other side is connected to the side wall of the support frame 4. Specifically, by including the mounting ring fixed to the outer ring bolt of the mixing tank 1 and the fixing frame with one end connected to the mounting ring and the other end connected to the side wall of the support frame 4, the mixing tank 1 is firmly anchored to one side of the support frame 4 during assembly, forming a rigid connection structure. This effectively resists the vibration and torque generated during the mixing process, thereby enhancing the overall structural stability, preventing the mixing tank 1 from shaking or shifting, and ensuring safe and reliable long-term operation.

[0019] Support rods are inclinedly installed on both sides of the bottom of the support plate 7. One end of the support rod is connected to the bottom of the support plate 7, and the other end is connected to the side wall of the support frame 4. Specifically, by setting up support rods inclined on both sides of the bottom of the support plate 7, with one end of the support rod connected to the bottom of the support plate 7 and the other end connected to the side wall of the support frame 4, a triangular mechanical structure is used to form bidirectional oblique support for the support plate 7 and the inoculum storage tank 6 and the transfer pump 9 above it. This significantly improves the load-bearing capacity and deformation resistance, and achieves the effect of preventing the support plate 7 from sagging or breaking due to equipment weight or vibration, ensuring the stability of the inoculum transfer system and smooth operation.

[0020] Example 3 Please see Figure 1-5As shown in this embodiment, a microbial inoculum addition device for feed production includes a drive structure comprising a drive motor 2 mounted on the top of a mounting plate 3, and a stirring structure comprising a rotating rod disposed inside a mixing tank 1 and several stirring rods connected to the outer ring of the rotating rod. The output shaft of the drive motor 2 is connected to the end of the rotating rod. Specifically, by including a drive motor 2 mounted on the top of the mounting plate 3 in the drive structure, and a rotating rod and several stirring rods connected to its outer ring inside the mixing tank 1 in the stirring structure, with the output shaft of the drive motor 2 connected to the end of the rotating rod, the drive motor 2 directly drives the rotating rod and stirring rods to rotate at high speed after starting, fully shearing and turning the main material in the tank, providing a good fluid state basis for the uniform dispersion of the subsequent microbial solution, achieving the effect of efficient and stable stirring, improving the uniformity of material mixing, and creating ideal dynamic conditions for the simultaneous addition of microbial inoculum.

[0021] The support frame 4 has sliding grooves 11 on both sides, and the bottom sides of the mounting plate 3 are fixedly connected to sliding rods 13 that slide in cooperation with the sliding grooves 11. The vertical lifting structure includes a lifting cylinder 15 connected to the bottom of one side of the support frame 4 via a side plate 12. The output end of the lifting cylinder 15 is connected to a lifting plate 14, and both ends of the lifting plate 14 are connected to two sliding rods 13 respectively. Specifically, the support frame 4 has sliding grooves 11 on both sides, and the bottom sides of the mounting plate 3 are fixedly connected to sliding rods 13 that slide in cooperation with the sliding grooves 11. The device includes a lifting cylinder 15 connected to the bottom of one side of the support frame 4 via a side plate 12. Its output end is connected to a lifting plate 14. The two ends of the lifting plate 14 are respectively connected to two sliding rods 13. When the lifting cylinder 15 extends or retracts, it pushes the lifting plate 14 to move up and down, thereby driving the two sliding rods 13 to slide vertically along the sliding groove 11. This allows for overall adjustment of the height of the mounting plate 3 and the carrying mixing structure, achieving precise adjustment of the insertion depth of the mixing structure, facilitating cleaning and maintenance, adapting to different material level conditions, and ensuring a smooth lifting process without swaying.

[0022] The slide rod 13 is made of metal and its length is greater than the length of the sliding groove 11. Specifically, by making the slide rod 13 of metal and setting its length to be greater than the length of the sliding groove 11, even if the slide rod 13 is fully extended out of the sliding groove 11 during the lifting process, it can still maintain a sufficient guide section embedded in the groove, avoiding derailment or jamming due to the travel limit. The metal material ensures high strength and wear resistance, thereby improving the operational reliability of the lifting mechanism, extending its service life, and preventing the interruption of stirring or equipment damage due to structural failure.

[0023] The working process of the microbial inoculum addition device for feed production of the present invention is as follows: First, the main ingredients, such as grains and soybean meal, are added to the mixing tank 1. The mixing tank 1 is securely connected to one side of the support frame 4 by several mounting brackets 10. Each mounting bracket 10 consists of a mounting ring bolted to the outer ring of the mixing tank 1 and a fixing bracket connected at one end to the mounting ring and at the other end to the side wall of the support frame 4, ensuring the rigidity of the overall structure. Then, the drive motor 2 installed on the top of the mounting plate 3 is started, and its output shaft drives the rotating rod located inside the mixing tank 1 to rotate. Multiple stirring rods connected to the outer ring rotate synchronously to thoroughly mix the main material. Simultaneously, the active microbial solution stored in the inoculum storage tank 6 is drawn out by a transfer pump 9, which is installed at the bottom of the support plate 7. Its input end is connected to the inoculum storage tank 6, and its output end is connected to a spray ring 5 surrounding the top edge of the mixing tank 1 via a connecting pipe. During the mixing process, the transfer pump 9 continuously pumps the inoculum solution into the spray ring 5, and then evenly sprays it onto the surface of the churning material through multiple spray pipes 8 penetrating the top of the mixing tank 1, achieving simultaneous mixing of the inoculum and the main material. The mixing process is as follows: Support rods are inclinedly arranged on both sides of the bottom of the support plate 7. One end of each support rod is connected to the bottom of the support plate 7, and the other end is connected to the side wall of the support frame 4, forming a triangular stable structure to support the weight of the inoculum storage tank 6 and the transfer pump 9. The mounting plate 3 slides with sliding grooves 11 on both sides of the support frame 4 via sliding rods 13 fixed on both sides of its bottom. Its height is adjusted by a vertical lifting structure, which includes a lifting cylinder 15 fixed to the bottom of one side of the support frame 4 via a side plate 12. The output end of the cylinder is connected to a lifting plate 14. The lifting plate 14 has two... The ends are respectively fixedly connected to two slide rods 13. When the lifting cylinder 15 extends or retracts, it drives the lifting plate 14 and slide rods 13 to move vertically along the sliding groove 11, thereby adjusting the height of the mounting plate 3, its drive motor 2 and stirring structure as a whole, so as to adapt to different material levels or to carry out equipment maintenance. The slide rods 13 are made of metal and are longer than the length of the sliding groove 11, ensuring that there is still enough guide section embedded in the groove at the maximum stroke to prevent derailment. The entire process of adding and mixing bacteria is completed continuously in the sealed mixing tank 1 without stopping the machine or connecting external equipment.

[0024] By integrating the inoculum storage tank 6, transfer pump 9, spray ring 5, and spray pipe 8 into one unit, and directly connecting it to the mixing tank 1, a closed and automated operation for adding inoculum is achieved, eliminating manual intervention and secondary connection steps. Addressing the issue of uneven distribution due to subsequent inoculum addition, the spray pipe 8 simultaneously sprays the inoculum solution during the mixing process. Combined with the efficient mixing of the rotating rod and stirring rod, this ensures rapid and uniform dispersion of the inoculum in the main ingredient, significantly improving batch consistency and inoculum activity retention. The surrounding spray ring 5 ensures multi-point coverage, preventing excessively high local concentrations. The mounting frame 1... The rigid connection structure of the 0 effectively suppresses displacement caused by stirring vibration, ensuring operational safety; the drive motor 2 directly drives the stirring structure to provide stable power and enhance the mixing effect; the support plate 7, together with the inclined support rods on both sides, forms a stable load-bearing system to prevent deformation or loosening due to the equipment's own weight or vibration; the lifting cylinder 15, lifting plate 14, slide rod 13 and sliding groove 11 work together to form a precise lifting mechanism, realizing flexible adjustment of the stirring depth. At the same time, the slide rod 13 is made of high-strength metal and its length is greater than that of the sliding groove 11, ensuring that the lifting process is stable and reliable, without the risk of jamming or derailment.
