Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a solid mixed feed additive feeding device. Background Technology

[0002] In the process of large-scale and intensive development of modern animal husbandry, feed additives, as key components for improving the nutritional value of feed and enhancing the production performance of livestock and poultry, directly affect breeding efficiency and the quality of livestock and poultry products through precise feeding and uniform mixing. Solid mixed feed additives, due to their diverse components (such as vitamins, minerals, enzymes, etc.), large differences in form (powder, granules), and the fact that some components are hygroscopic or prone to clumping, place strict requirements on the stability, accuracy, and adaptability of feeding devices.

[0003] In the prior art, such as Chinese Patent No. CN217646233U, a base is included, with a mixing box fixedly connected to the top of the base. A mixing assembly is installed inside the mixing box, and a support plate is fixedly connected to the left outer wall of the mixing box. A feeding assembly is installed on the top of the support plate. This device uses the feeding assembly to evenly distribute powdered feed from the shell onto the top of the solid feed in the mixing box along the feed guide pipe. Powdered feed is added while the solid feed is being mixed, thus ensuring thorough mixing of the solid and powdered feeds and preventing the powdered feed from agglomerating. This ensures efficient mixing of the solid and powdered feeds. During the mixing process, the mixing assembly scrapes the powdered feed adhering to the inner wall of the mixing box, facilitating cleaning and preventing the accumulation of powdered feed on the inner wall of the mixing box over long-term use, which can cause contamination and damage to the feed. This is beneficial for long-term use.

[0004] While the above solutions offer advantages, they also have disadvantages. Existing feeding components rely on shell vibration and a grid bottom to dispense powdered materials, making them suitable only for single-size powders. Furthermore, the feeding rate cannot be precisely controlled, leading to feeding interruptions or fluctuations when dealing with hygroscopic or easily agglomerated additives. This fails to meet the feeding needs of diverse solid additives. Additionally, the existing structure lacks a heating jacket and heating tube, making it prone to agglomerating and clogging the shell grid for highly hygroscopic additives due to environmental humidity or the material's own characteristics. This results in continuous feeding, requiring frequent manual cleaning and impacting feeding efficiency. Moreover, the shell grid holes rely solely on natural vibration or manual cleaning, which cannot simultaneously remove residual fine agglomerated materials during vibration. Long-term use can exacerbate grid clogging, further reducing feeding stability. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology that rely on shell vibration and grid bottom to feed powdered materials, which is only suitable for powders of a single particle size and cannot accurately control the feeding amount.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please see Figures 1-5 This embodiment provides a solid mixed feed additive feeding device, the specific idea of ​​which is as follows: A solid mixed feed additive feeding device includes a mixing tank 1, and the solid mixed feed additive feeding device further includes: a fixing ring 3, a shell 5, two sliding grooves 12, two sliders 14, a filter plate 8, a heating jacket 4, multiple heating tubes 11 and two snap-fit ​​components.

[0027] The fixing ring 3 is set at the top opening edge of the mixing tank 1, and the central axis of the fixing ring 3 is collinear with the central axis of the mixing tank 1 to ensure the coaxiality of subsequent component assembly.

[0028] In addition, the housing 5 adopts a hollow structure with an opening at the top and a reserved installation position at the bottom. Its outer side wall is nested with the inner side wall of the fixing ring 3 through a clearance fit. The housing 5 can be flexibly disassembled and assembled along the axial direction of the fixing ring 3.

[0029] In addition, two swivels 12 are symmetrically opened on the inner walls of the housing 5 on both sides, and the length of the swivels 12 is adapted to the height of the inner wall of the housing 5.

[0030] Two sliders 14 are respectively installed in two slide grooves 12 through sliding fit, and the outer wall of the slider 14 is closely fitted with the inner wall of the slide groove 12.

[0031] In addition, the filter plate 8 is horizontally set at the bottom of the inner cavity of the housing 5, and the two sides of the filter plate 8 are respectively fixedly connected to the opposite side of the two sliders 14 by bolts, so that the filter plate 8 moves synchronously with the sliders 14 along the slide groove 12.

[0032] The heating sleeve 4 is fitted onto the outer side of the housing 5 by engaging with the annular groove 13 on the outer side of the housing 5 through a pre-set annular protrusion on the inner side wall. The heating sleeve 4 and the housing 5 have no gaps in their contact surfaces, ensuring efficient heat transfer.

[0033] In addition, multiple heating tubes 11 are embedded in the inner cavity of the heating sleeve 4 in a ring array. The two ends of the heating tubes 11 are electrically connected to the terminals at both ends of the heating sleeve 4, and the outer wall of the heating tubes 11 is fixed to the inner cavity wall of the heating sleeve 4 by a high-temperature resistant adhesive.

[0034] Two snap-fit ​​components are fixed to the bottom of the two sliders 14 by bolts. The central axis of the snap-fit ​​components is collinear with the central axis of the sliders 14 to ensure force balance.

[0035] As examples, in this embodiment, the snap-fit ​​component includes: a fixing block 21, two connecting cylinders 19, two elastic elements 18, a second pull rope 20, and a first pull rope 16.

[0036] The fixed block 21 is a rectangular block structure, and its top is fixedly connected to the bottom of the slider 14 by welding.

[0037] In addition, two connecting cylinders 19 are symmetrically welded to the outer walls of the two sides of the fixing block 21. The connecting cylinder 19 is a hollow cylindrical structure with one end open and the other end closed. The axis of the connecting cylinder 19 is perpendicular to the side wall of the fixing block 21.

[0038] In addition, two elastic elements 18 are respectively embedded inside the two connecting cylinders 19. The elastic element 18 is a compression spring 22, one end of which is welded and fixed to the inner wall of the closed end of the connecting cylinder 19, and the other end is connected to the corresponding block 17.

[0039] Two locking blocks 17 are respectively slidably fitted at the open ends of the two connecting cylinders 19. The outer wall of the locking block 17 is tightly fitted with the inner wall of the connecting cylinder 19. The ends of the two locking blocks 17 away from the elastic element 18 extend out of the connecting cylinder 19, and both are elastically telescopically fitted with the connecting cylinder 19 through the elastic element 18.

[0040] In addition, the second pull rope 20 passes through the transverse through hole opened inside the fixed block 21 and the rope hole preset on the side wall of the connecting cylinder 19. The second pull rope 20 is in sliding fit with the fixed block 21 and the connecting cylinder 19. The two ends of the second pull rope 20 are respectively fixedly connected to the ends of the two locking blocks 17 near the elastic member 18.

[0041] In addition, the first pull rope 16 passes through the vertical through hole opened inside the slider 14 and the corresponding vertical through hole inside the fixing block 21. The first pull rope 16, slider 14, and fixing block 21 are all in sliding fit. The bottom end of the first pull rope 16 and the middle part of the second pull rope 20 are fixedly connected by knotting to form a linkage traction structure.

[0042] In this embodiment, the slider 14 slides along the groove 12, causing the filter plate 8 to move. The elastic element 18 in the snap-fit ​​component pushes the snap-fit ​​block 17 into the slot 13 of the housing 5, thus positioning the filter plate 8. Pulling the pull rope can retract the snap-fit ​​block 17, releasing the positioning and adjusting the position of the filter plate 8. The heating sleeve 4 is tightly fitted to the housing 5 through snap-fit. The heating tube 11 is energized to generate heat and transfers it to the housing 5, preventing the additive from absorbing moisture and clumping. The filter plate 8 screens the additives, and qualified additives fall into the mixing tank 1. The structure between the heating sleeve 4 and the fixing ring 3 can buffer the heating deformation, ensuring a stable feeding process and meeting the needs of precise feeding of solid additives.

[0043] Example 2: Please see Figures 1-5 Based on Example 1, this example provides a solid mixed feed additive feeding device, the specific idea of ​​which is as follows: The solid mixed feed additive feeding device also includes: two slots 13, two pull rings 15, multiple springs 22, four fixing frames 2, and cleaning components.

[0044] The two slots 13 are symmetrically opened on the outer walls of the two sides of the housing 5. Both slots 13 are connected to the corresponding sliding grooves 12. The groove size of the slot 13 is adapted to the end size of the block 17 extending out of the connecting cylinder 19. The blocks 17 of the two snap-fit ​​parts can respectively form a snap-fit ​​engagement with the two slots 13 to realize the positioning and fixing of the filter plate 8.

[0045] In addition, the two pull rings 15 are fixed to the top of the two sliders 14 by welding. The inner rings of the two pull rings 15 are fixedly connected to the top of the first pull rope 16 on the corresponding side. Pulling the pull rings 15 can drive the first pull rope 16 to move synchronously.

[0046] In addition, multiple springs 22 are elastic columns made of silicone material and are arranged in a ring array on the side wall of the inner cavity of the fixing ring 3. One end of each spring 22 is fixedly connected to the inner side wall of the fixing ring 3 by adhesive bonding, and the other end is fixedly connected to the outer side wall of the heating sleeve 4 by adhesive bonding, forming a buffer support between the heating sleeve 4 and the fixing ring 3.

[0047] The four fixing frames 2 are installed symmetrically on the outer walls of both sides of the mixing tank 1 in two groups. The two fixing frames 2 in each group are arranged vertically. The bottom of the two fixing frames 2 are fixedly connected to the side wall of the mixing tank 1 by bolts, and the top of the two fixing frames 2 are fixedly connected to the outer wall of the fixing ring 3 by welding, forming the auxiliary support structure of the fixing ring 3.

[0048] In addition, the cleaning component is detachably installed on the top of the housing 5 via a snap-fit ​​structure, and the working end of the cleaning component extends into the inner cavity of the housing 5 to correspond and fit with the surface of the filter plate 8. As examples, in this embodiment, the cleaning components include: a support plate 7, a rotating shaft 9, a detachable brush 10, and a motor 6.

[0049] The support plate 7 is designed to engage with the top edge of the housing 5 via pre-set claws on both sides, and can be detachably installed on one side of the top of the housing 5.

[0050] In addition, the rotating shaft 9 is rotatably mounted in the mounting seat at the bottom of the support plate 7 via a bearing. The central axis of the rotating shaft 9 is set vertically, and the rotating shaft 9 can rotate flexibly around its own axis.

[0051] In addition, the detachable brush 10 is installed on the outer wall of the bottom end of the rotating shaft 9 by means of threaded connection. The bottom of the bristles of the detachable brush 10 is in contact with the surface of the top of the filter plate 8, and the length of the brush is consistent with the mesh thickness of the filter plate 8 to ensure cleaning coverage.

[0052] The motor 6 is fixedly installed on one side of the top of the support plate 7 by bolts. The output shaft of the motor 6 is fixedly connected to the top of the rotating shaft 9 by a coupling. After the motor 6 is started, it can drive the rotating shaft 9 and the detachable brush 10 to rotate synchronously.

[0053] In this embodiment, the slot 13 and the block 17 are adapted to each other and fix the position of the filter plate 8 by snap-fit. The pull ring 15 can pull the pull rope to retract the block 17, thereby unlocking and adjusting the filter plate 8. The spring 22 connects the fixing ring 3 and the heating sleeve 4, buffering the deformation of the heating sleeve 4 and maintaining the fit. The fixing frame 2 symmetrically supports the fixing ring 3, enhancing the overall structural stability. In the cleaning component, the support plate 7 is fixed by snap-fit. The motor 6 drives the rotating shaft 9 to rotate, which drives the detachable brush 10 to clean the surface of the filter plate 8. The fit design between the brush and the filter plate 8 ensures cleaning coverage. The detachable structure facilitates the maintenance and replacement of the brush. The whole system realizes the functions of cleaning the filter plate 8, stable support of the device, and flexible adjustment of the components.

[0054] Working principle: In use, solid powdered feed additives are added to the inside of the housing 5. The additives fall onto the filter plate 8, and the filter holes of the filter plate 8 perform preliminary screening of the additives, removing lumpy particles. At the same time, solid basic feed is added to the mixing tank 1 through the feeding structure (described in detail in the original comparative examples, so it will not be repeated in this application), completing the material preparation before feeding. According to the characteristics of the additives, multiple heating tubes 11 in the heating jacket 4 are activated. The heat generated by the heating tubes 11 is transferred to the housing 5 through the heating jacket 4 to heat the additives in the housing 5 at a low temperature, preventing the additives from clogging the filter holes of the filter plate 8 due to moisture absorption and clumping. During the heating process, the spring 22 can buffer the slight deformation of the heating jacket 4 caused by temperature changes, ensuring the fit between the heating jacket 4 and the housing 5. When the solid feed in the mixing tank 1 begins to be stirred (described in detail in the original comparative examples, so it will not be repeated in this application), the device enters the feeding stage.

[0055] If the height of the filter plate 8 needs to be adjusted to adapt to different feeding rates, the pull ring 15 can be pulled. The pull ring 15 drives the first pull rope 16 to move upward. The first pull rope 16 pulls the second pull rope 20 to tighten simultaneously. The second pull rope 20 pulls the two locking blocks 17 to retract into the connecting cylinder 19, compressing the elastic element 18, so that the locking blocks 17 disengage from the locking groove 13 of the housing 5, releasing the fixed state of the filter plate 8. Then, the slider 14 slides up and down along the slide groove 12 to adjust the filter plate 8 to the target height. The pull ring 15 is released, the elastic element 18 resets and pushes the locking blocks 17 to re-engage into the corresponding locking groove 13, completing the positioning of the filter plate 8. After the filter plate 8 is fixed, the powdered additive in the housing 5 falls through the filter holes of the filter plate 8 and enters the mixing box 1 through the material guiding structure at the bottom of the housing 5, mixing with the solid feed being stirred. If the additive falls slowly, the external vibration component (described in detail in the original comparative example, so it will not be repeated in this application) can be used to assist in feeding to ensure uniform feeding.

[0056] When a single feeding is completed or when a large number of agglomerated particles remain on the top surface of the filter plate 8, the cleaning device is activated, the motor 6 is powered on and runs, the output end of the motor 6 drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the detachable brush 10 at the bottom to rotate synchronously, the brush makes a circular motion on the top surface of the filter plate 8 to break up the agglomerated particles on the filter plate 8, making it easier for subsequent manual cleaning. If the filter plate 8 needs to be deeply cleaned or replaced, repeat the filter plate 8 unlocking steps, pull the pull ring 15 to make the locking block 17 disengage from the locking groove 13, and then slide the slider 14 upward along the slide groove 12 to take the filter plate 8 out from the opening at the top of the housing 5, completing the disassembly of the filter plate 8. After cleaning, align the slider 14 with the slide groove 12 and insert it, slide it to the target position and fix it with the locking device to realize the reset of the filter plate 8.
