Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and in particular to a feed raw material quantitative distribution device that improves the accuracy of ingredient mixing. Background Technology

[0002] In the feed production process of livestock farming, the precision of raw material formulation is crucial to ensuring nutritional balance and product quality. Strict quantitative allocation of various grains, soybean meal, and additives is necessary before mixing. However, feed ingredients are highly susceptible to moisture absorption due to environmental humidity during storage and transportation, or may clump due to prolonged stacking and pressure. This instability in the physical state of the raw materials poses significant challenges to the subsequent quantitative feeding process.

[0003] Existing feed ingredient distribution devices typically employ gravity-feed hoppers controlled by bottom-mounted gate valves or butterfly valves. This traditional structure has significant shortcomings: First, due to the lack of a pre-treatment mechanism for raw materials, when raw materials containing large particles, lumps, or impurities directly enter the feeding channel, they are prone to "arching" or blockage at the constriction, leading to feeding interruptions or highly unstable flow rates. Once the lumps suddenly disintegrate, it can cause an instantaneous spill of material. This uncontrollable flow rate fluctuation results in significant errors in time- or volume-based metering methods.

[0004] Furthermore, existing feed control valves are mostly simple linear opening and closing or manual operation, lacking precise adjustment capabilities. When dealing with materials with poor flowability or containing hard lumps, the valves often fail to quickly and tightly cut off the material flow, easily leading to leakage due to incomplete closure, or the actual feed volume far exceeding the preset value due to sluggish operation. The aforementioned unevenness of raw material conditions combined with the coarseness of the control mechanism severely restricts the improvement of feed formulation accuracy, making it difficult to meet the needs of modern high-standard feed production.

[0005] Therefore, this utility model proposes a feed ingredient quantitative distribution device to improve the accuracy of ingredient mixing, in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a feed ingredient quantitative distribution device to improve the accuracy of ingredient dispensing. It aims to improve the structural defects of existing feed ingredients that cause blockage and uneven flow rate due to moisture clumping, as well as the difficulty of traditional valve control in balancing anti-blocking and high-precision dispensing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a feed ingredient quantitative distribution device for improving the accuracy of ingredient mixing, comprising: a support frame, and a storage bin fixedly installed on the top of the support frame, the bottom of the storage bin being connected to a discharge pipe; and a vibrating screening mechanism disposed inside the storage bin and a quantitative opening and closing mechanism disposed at the discharge pipe.

[0008] The storage hopper is equipped with a sieve plate inside, and a sliding ring is fixedly fitted on the outer wall of the sieve plate. The outer wall of the sliding ring slides against the inner wall of the storage hopper. A vibration motor is installed at the bottom of the sieve plate. A fixing ring is fixedly installed on the inner wall of the storage hopper below the sliding ring. An elastic support component connects the fixing ring and the sliding ring.

[0009] Furthermore, a fixing plate and a fixing column are fixedly installed on the outer wall of the feeding pipe. A hydraulic rod is rotatably connected to the outer wall of the fixing plate. A rotating cover is rotatably sleeved on the outer wall of the fixing column. The output end of the hydraulic rod is rotatably connected to the outer wall of the rotating cover. When the rotating cover is rotated to the closed state, it covers the outlet at the bottom of the feeding pipe.

[0010] Preferably, the elastic support assembly includes a lower limiting post fixed to the top of the fixed ring and an upper limiting post fixed to the bottom of the sliding ring. A spring is sleeved between the outer walls of the lower limiting post and the upper limiting post, and the two ends of the spring abut against the bottom of the sliding ring and the top of the fixed ring, respectively.

[0011] Preferably, the bottom of the storage hopper is provided with a flat conical barrel, the large-diameter end of the flat conical barrel is welded and fixed to the bottom of the storage hopper, and the small-diameter end of the flat conical barrel is connected to the top of the discharge pipe.

[0012] Preferably, the top of the storage hopper is rotatably connected to a flap via a hinge, and the flap covers the inlet of the storage hopper.

[0013] Preferably, the surface of the sieve plate has a plurality of evenly distributed sieve holes, and the vibration motor is located at the center of the lower surface of the sieve plate.

[0014] Preferably, a controller is fixedly installed on one side of the outer wall of the feeding pipe, and the controller is electrically connected to the hydraulic rod and the vibration motor through wires.

[0015] Preferably, a receiving frame is placed on the bottom inner side of the support frame and directly below the discharge pipe, the receiving frame being used to receive the material discharged from the discharge pipe.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of existing feed raw materials clumping due to moisture and clogging of the feed pipe, as well as large fluctuations in flow rate due to uneven particle size, by setting a suspended vibrating screening mechanism inside the storage tank. It utilizes the sliding cooperation between the sliding ring and the inner wall of the storage tank and the elastic support of the spring. This achieves the technical effect of pre-screening impurities and breaking up clumps, ensuring that the raw materials entering the feeding stage are loose and uniform, thus providing a material basis for improving the accuracy of batching. At the same time, the elastic buffer effectively reduces the rigid impact of vibration on the main structure of the equipment, extending the service life of the equipment.

[0017] 2. This utility model solves the problem of traditional gate valves having difficulty in accurately controlling the opening degree and time, and being easily affected by material blockage, resulting in delayed action, by using a controller to control the hydraulic rod to drive the rotating cover to rotate around the fixed column. It achieves the technical effect of stepless adjustment and rapid opening and closing of the feed inlet, and accurately controlling the feed amount by precisely controlling the stroke and action time of the hydraulic rod, thus significantly improving the accuracy of quantitative distribution of feed raw materials.

[0020] 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.

[0021] Reference Figures 1-4 This utility model provides an embodiment of a feed ingredient quantitative dispensing device for improving batching accuracy. The device includes a support frame 1, which serves as the mounting base for the entire device, providing stable support. A storage bin 2 is fixedly installed on the top of the support frame 1. The storage bin 2 is used to centrally hold the feed ingredients to be dispensed. To facilitate ingredient dispensing and ensure proper sealing, a flip cover 202 is rotatably connected to the top of the storage bin 2 via a hinge 201. The flip cover 202 covers the feed inlet of the storage bin 2, preventing external dust from mixing into the ingredients. The bottom of the material hopper 2 is connected to the discharge pipe 4. Specifically, the bottom of the material hopper 2 is provided with a flat cone 203. The large diameter end of the flat cone 203 is welded and fixed to the bottom of the material hopper 2, and the small diameter end of the flat cone 203 is connected to the top of the discharge pipe 4. Through the conical guiding effect of the flat cone 203, the processed material can be smoothly collected into the discharge pipe 4. A receiving frame 3 is placed on the bottom inner side of the support frame 1 and directly below the discharge pipe 4. The receiving frame 3 is used to receive the material discharged from the discharge pipe 4 to complete the final quantitative collection. The sieve plate 5 is horizontally set inside the storage tank 2. The surface of the sieve plate 5 has several evenly distributed sieve holes 501, which are used to filter and screen the raw materials. A sliding ring 502 is fixedly sleeved on the outer wall of the sieve plate 5. The outer wall of the sliding ring 502 slides against the inner wall of the storage tank 2. The sliding engagement restricts the horizontal displacement of the sieve plate 5, while allowing the sieve plate 5 to generate vibration displacement in the vertical direction. A vibration motor 504 is fixedly installed at the center of the lower surface of the sieve plate 5. The vibration motor 504 serves as the excitation source to provide high-frequency vibration force to the sieve plate 5. In order to achieve elastic support for the sieve plate 5 and buffer the rigid impact of the vibration force on the storage tank 2, a fixing ring 503 is fixedly installed on the inner wall of the storage tank 2 and below the sliding ring 502. An elastic support component is connected between the fixing ring 503 and the sliding ring 502.

[0022] Specifically, the elastic support assembly includes a lower limiting post 506 fixed to the top of the fixed ring 503 and an upper limiting post 507 fixed to the bottom of the sliding ring 502. The lower limiting post 506 and the upper limiting post 507 are coaxially corresponding in the vertical direction. A spring 505 is sleeved between the outer walls of the lower limiting post 506 and the upper limiting post 507. The two ends of the spring 505 abut against the bottom of the sliding ring 502 and the top of the fixed ring 503, respectively. This suspension structure composed of the sliding ring 502, the spring 505 and the limiting post can not only support the weight of the screen plate 5 and the raw material, but also generate stable high-frequency vibration of the screen plate 5 by utilizing the reciprocating compression and rebound characteristics of the spring 505 when the vibrating motor 504 is working. This breaks up the clumps and allows the qualified raw material to pass through the screen hole 501 quickly, effectively avoiding material blockage and ensuring the looseness and uniformity of the falling material. To achieve automated and precise control of the feeding process and improve the accuracy of batching, a fixing plate 401 and a fixing column 404 are fixedly installed on the outer wall of the feeding pipe 4. A hydraulic rod 402 is rotatably connected to the outer wall of the fixing plate 401 via a pin. A rotating cover 403 is rotatably fitted onto the outer wall of the fixing column 404. The rotating cover 403 can rotate around the fixing column 404. The output end of the hydraulic rod 402 is rotatably connected to the outer wall of the rotating cover 403. When the rotating cover 403 is rotated to the closed state, it can completely cover the outlet at the bottom of the feeding pipe 4. To achieve intelligent control, a controller 405 is fixedly installed on one side of the outer wall of the feeding pipe 4. The controller 405, the hydraulic rod 402, and the vibration motor 504 are all electrically connected via wires. The controller 405 can precisely adjust the opening angle and opening duration of the rotating cover 403 by controlling the extension and retraction stroke and time of the hydraulic rod 402, thereby achieving precise control of the feeding quantity.

[0023] Working principle: When the entire device is supported and fixed by the support frame 1, the operator first opens the flip cover 202 connected by the hinge 201 and pours the feed raw materials to be processed into the storage tank 2. Then, the controller 405 starts the vibration motor 504 installed at the bottom of the screen plate 5. The vibration force generated by the vibration motor 504 drives the sliding ring 502 and the screen plate 5 to vibrate at high frequency. Since the sliding ring 502 is slidably connected to the inner wall of the storage tank 2, and a spring 505 is sleeved between the lower limit post 506 at the top of the fixed ring 503 and the upper limit post 507 at the bottom of the sliding ring 502, the spring 505 reciprocates under the action of the vibration force, thereby providing elastic support for the screen plate 5 and limiting its vibration amplitude. During this process, qualified fine raw materials pass through the screen holes 501 and fall into the flat cone 203 below and collect in the feed pipe 4, while unqualified large particles or clumps are intercepted above the screen plate 5, thereby ensuring that the raw materials entering the feed pipe 4 are loose and uniform, and preventing blockage in the subsequent feeding process.

[0024] When quantitative feeding is required, the controller 405 controls the hydraulic rod 402 to move according to the preset program. Since the bottom of the hydraulic rod 402 is rotatably connected to the fixed plate 401, and the output end of the hydraulic rod 402 is rotatably connected to the outer wall of the rotating cover 403, and the rotating cover 403 is rotatably installed on the outer wall of the feeding pipe 4 through the fixed column 404, when the hydraulic rod 402 moves in extension and retraction, it will push the rotating cover 403 to rotate around the fixed column 404 as the center. The rotation of the rotating cover 403 realizes the opening or closing of the bottom outlet of the feeding pipe 4. The controller 405 accurately controls the amount of raw material falling into the receiving frame 3 by precisely controlling the extension and retraction stroke and opening time of the hydraulic rod 402. Since the raw material has undergone the previous vibration screening treatment, the flow rate is stable, thereby effectively improving the batching accuracy and completing the quantitative distribution operation.
