Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to a duck feed pelleting mechanism. Background Technology

[0002] In duck feed production, pelleting is a crucial process for ensuring feed palatability and feed suitability. It typically involves using pelleting equipment to process feed ingredients into fine, granular strips to meet the ducks' feeding needs. The core operating logic of existing pelleting equipment is as follows: continuous pressure is applied to the feed ingredients using rollers, causing the ingredients to be squeezed through tiny holes in the pelleting plate to form continuous, fine strips, which are then further processed into pelleted feed.

[0003] However, in actual production, feed ingredients are prone to problems such as compression adhesion and pellet agglomeration, which can cause blockage of the granulation plate's holes. Current solutions to this blockage often require disassembling the entire equipment and then replacing the granulation plate or manually clearing the blockage. This not only disrupts the original assembly of the equipment and prolongs downtime, but also significantly increases spare parts wear and tear costs as well as labor costs, negatively impacting the continuity and economy of duck feed production. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a duck feed pelleting mechanism to solve the problem of low efficiency of manual unclogging in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a duck feed pelleting mechanism, including: a support with a control cabinet; a cylinder, the cylinder being fixed on the support, and a blockage clearing mechanism being provided inside the cylinder; a pelleting plate, the pelleting plate being disposed inside the cylinder; and a pressing roller, the pressing roller being disposed inside the cylinder; wherein, two pelleting plates are provided, the two pelleting plates together forming a pelleting component, and the pelleting plates are driven by a lead screw to move within the cylinder.

[0006] Optionally, the unblocking mechanism includes a receiving part fixed to both sides of the cylinder, the receiving part having a plurality of through holes, and the granulating plate having a plurality of granulation holes, wherein the granulation holes overlap with the through holes when the granulating plate enters the receiving part.

[0007] Optionally, the unblocking mechanism further includes an unblocking component, which is provided with a plurality of unblocking heads that cooperate with the through hole, and a handle is also fixed on the unblocking component.

[0008] Optionally, the lead screw is rotatably connected to the storage part, and one end of the lead screw is connected to the other through a transmission assembly. One end of one of the lead screws is connected to a second motor, which is fixed to the bracket.

[0009] Optionally, the lead screw is a forward and reverse lead screw, and a fixing part is provided in the middle of the lead screw.

[0010] Optionally, both sides of the granulation plate are fixed with protrusions, which are threaded to the lead screw. The granulation plate is also provided with notches, which together form a shaft hole.

[0011] Optionally, a rotating shaft is rotatably connected inside the cylinder, the rotating shaft passes through the shaft hole, a first motor is fixed on the bracket, the output shaft of the first motor is connected to the rotating shaft through a reducer, and the rolling roller is rotatably connected to the rotating shaft.

[0012] Optionally, a scraper is also fixed on the rotating shaft, and a flexible part is fixed on the side of the scraper near the granulation plate.

[0013] Optionally, the rolling roller is provided with a protrusion, and the granulation plate is provided with a recess that matches the protrusion.

[0014] Optionally, a discharge guide plate is also fixed inside the cylinder. The discharge guide plate is inclined, the rotating shaft passes through the discharge guide plate, and a discharge port that cooperates with the discharge guide plate is opened on the cylinder.

[0015] The beneficial effects of this utility model are as follows: In this invention, the pelletizing component consists of two pelletizing plates, which move close together or apart via a lead screw. When the two pelletizing plates approach each other, they can close together to form the pelletizing component, which is then used in conjunction with the rolling roller for pelletizing. When unclogging is required, the lead screw drives the two pelletizing plates apart, allowing the unclogging mechanism to perform unclogging operations on a single pelletizing plate. The entire operation requires no disassembly or reassembly of the original equipment structure, shortening downtime for maintenance, effectively improving the overall operating efficiency and production continuity of the equipment, and reducing equipment maintenance costs.

[0016] Meanwhile, by setting a concave portion on the pelleting plate and a convex portion on the rolling roller, and adapting the convex portion to the concave portion, when the feed raw material is poured into the cylinder, the concave portion can effectively guide the raw material, thereby limiting the radial displacement of the raw material and preventing the raw material from being pushed to the edge of the cylinder and causing accumulation. This reduces raw material waste and lowers the risk of local blockage caused by accumulation, further optimizing the efficiency and stability of the pelleting process. Attached Figure Description

[0024] 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.

[0025] As mentioned earlier, in actual production, existing duck feed pelleting mechanisms are prone to problems such as feed raw materials sticking together due to compression and pellet agglomeration, leading to blockage of the holes in the pelleting plate. Current solutions to this blockage often require disassembling the entire equipment and then replacing the pelleting plate or manually clearing the blockage. This not only disrupts the original assembly of the equipment and prolongs downtime but also significantly increases spare parts wear and tear costs as well as labor costs, negatively impacting the continuity and economy of duck feed production.

[0026] To address this issue, this utility model provides a pelleting mechanism that solves the problem of easy clogging in the pelleting components during duck feed production. By using two pelleting plates to enclose a single pelleting component, the mechanism allows for the displacement and separate treatment of the two plates during clogging, thus achieving efficient clogging removal without disassembling the equipment. This utility model solves the problem in the following way.

[0027] Example 1: Please refer to the accompanying drawings in the specification. This embodiment provides a duck feed pelleting mechanism. The structure includes, as shown in the attached drawings, the following components: Figure 1 The bracket 1 shown has a control cabinet 9 on it that controls the start and stop of the entire equipment. The other end of the control cabinet 9 has a cylinder 2 that is also fixed on the bracket 1.

[0028] like Figures 2 to 3 As shown, in this embodiment, the cylinder 2 has an opening away from the support 1 (facing upwards), and a discharge port 22 is also provided on the bottom side of the cylinder 2 away from the support 1. When in use, the raw materials of duck feed enter from the opening at the top, are crushed into pellets, and are discharged from the discharge port 22.

[0029] like Figures 2 to 3 , Figure 5As shown, in this embodiment, a storage section 21 is provided outside the cylindrical body 2. The storage section 21 is hollow and connects to the interior of the cylindrical body 2. Two lead screws 31 are rotatably connected inside the storage section 21. One end of each lead screw 31 passes through the storage section 21 and is connected via a transmission assembly 81. The transmission assembly 81 includes transmission wheels (e.g., sprockets, pulleys) connected to the two lead screws 31 respectively, and a transmission belt (e.g., chain, belt) connected between the two transmission wheels. One of the lead screws 31 is connected to a second motor 8. A protective shell is fitted over the second motor 8 and is fixed to the bracket 1.

[0030] Lead screw 31 is a forward and reverse lead screw, and a fixing part 32 is provided in the middle of lead screw 31 (e.g., Figure 6 As shown, the lead screw 31 has two threaded grooves extending from the fixed part 32 to both ends, and the helical directions of these two threaded grooves are opposite. At the same time, the cylinder 2 is provided with two opposing granulation plates 3, and both ends of the granulation plates 3 are fixedly connected to protrusions 33, which are threaded to the lead screw 31. Therefore, when the lead screw 31 is driven to rotate by the second motor 8, the two granulation plates 3 move closer or further apart under the action of the threads. The granulation plates 3 have notches 34 in the middle, and the two notches 34 close together to form a shaft hole when the granulation plates 3 are close together.

[0031] like Figures 1 to 3 As shown in this embodiment, the receiving part 21 has several through holes 24, which extend vertically. When the two granulating plates 3 are moved away from each other to their maximum distance, the granulating plates 3 are located inside the receiving part 21, and the granulation holes on the granulating plates 3 overlap with the through holes 24 (corresponding one-to-one). At this time, the unblocking work can be completed by using an unblocking mechanism to clean the blockage in the granulation holes through the through holes 24.

[0032] like Figures 5 to 7 As shown in this embodiment, a pressing roller 4 is provided above the pelleting plate 3 for use with it. A rotating shaft 23 is rotatably connected inside the cylinder 2. The rotating shaft 23 passes through the shaft hole and is fixed with a secondary shaft, which is rotatably connected to the pressing roller 4. At the same time, the bottom of the rotating shaft 23 passes through the cylinder 2, and a first motor 7 is fixed on the bracket 1. The first motor 7 is connected to the rotating shaft 23 through a reducer 71. When the first motor 7 is powered on, it drives the rotating shaft 23 to rotate. The rotating shaft 23 drives the pressing roller 4 to rotate through the secondary shaft. The pressing roller 4 rotates close to the surface of the pelleting plate 3 and mixes the feed raw materials, so that the feed raw materials are squeezed. At the same time, the pressing roller 4 also rotates due to friction during the squeezing of the feed raw materials, thereby further squeezing the feed raw materials and making them pass through the pelleting holes to complete the pelleting operation.

[0033] like Figure 7As shown, in this embodiment, a scraper 5 is provided below the pelleting plate 3. The scraper 5 is fixed outside the rotating shaft 23 and rotates with the rotating shaft 23. The feed passes through the pelleting holes to form strips, and is finally cut into pellets of a fixed length by the scraper 5.

[0034] like Figure 6 As shown in this embodiment, a discharge guide plate 6 is provided on the outer sleeve of the rotating shaft 23. The discharge guide plate 6 is inclined towards the discharge port 22. The granular material falls onto the discharge guide plate 6, rolls out of the discharge port 22, and is eventually collected.

[0035] Example 2: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 4 As shown in the second embodiment, the mechanism further includes a blockage-clearing component, which is shaped as follows: Figure 4 The semi-circular shape shown (corresponding to the size of the granulation plate 3) indicates that the unblocking assembly includes an unblocking component 10, a handle 102 on the unblocking component 10, and several unblocking heads 101 on the reverse side of the handle 102 on the unblocking component 10.

[0036] Under normal conditions, the unblocking component 10 can be hung on the bracket 1 at any position via the handle 102. When needed, the operator operates the granulation plate 3 so that the granulation hole is aligned with the through hole 24 inside the storage part 21 as described in the previous embodiment. The operator then holds the handle 102 and presses the unblocking head 101 against the through hole 24 to remove the blockage and complete the unblocking process.

[0037] Example 3: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Three. For example... Figure 8 As shown, in this third embodiment, the pelletizing plate 3 has a recess 35. The recess 35 extends upward from the middle part of the pelletizing plate 3 towards the edge and center of the pelletizing plate 3, forming higher points at the edge and center of the pelletizing plate 3. Meanwhile, the pressing roller 4 has a protrusion 41, the curvature of which corresponds to the curvature of the recess 35. Furthermore, the bottom of the protrusion 41 is higher than the top of the recess 35, so that the pressing roller 4 will not obstruct the movement of the pelletizing plate 3.

[0038] A compression space is formed between the protrusion 41 and the concave portion 35. When the feed material enters the compression space, it will be guided along its shape into the lower part of the concave portion 35 and fill the compression space. As more feed material enters the compression space, the original feed material is squeezed into the pelleting hole under the action of the compression roller and pelleting is completed in the manner described in Example 1.

[0039] Therefore, in summary, compared with the prior art, this utility model and its embodiments have the following advantages, including but not limited to: In this invention, the pelletizing component consists of two pelletizing plates 3, which are driven by a lead screw 31 to move close together or apart. When the two pelletizing plates 3 approach each other, they can close together to form the pelletizing component, which is then used in conjunction with the rolling roller 4 for pelletizing. When unclogging is required, the lead screw 31 drives the two pelletizing plates 3 apart, allowing the unclogging mechanism to perform unclogging operations on a single pelletizing plate 3. The entire operation requires no disassembly or reassembly of the original equipment structure, shortening downtime for maintenance, effectively improving the overall operating efficiency and production continuity of the equipment, and reducing equipment maintenance costs.

[0040] Meanwhile, by providing a recess 35 on the pelleting plate 3 and a protrusion 41 on the rolling roller 4, and by adapting the protrusion 41 to the recess 35, the recess 35 can effectively guide the feed material after it is poured into the cylinder 2, thereby limiting the radial displacement of the material and preventing it from being pushed to the edge of the cylinder 2 and causing accumulation. This reduces material waste and lowers the risk of local blockage caused by accumulation, further optimizing the efficiency and stability of the pelleting process.

[0041] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
