Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and in particular to a feed pelleting device for improving pellet uniformity. Background Technology

[0002] Feed pelleting equipment is a core piece of equipment in the feed industry. Its main function is to process uniformly mixed powdered materials into pellets of a certain shape and size through mechanical extrusion. Compared with powdered feed, pelleted feed is more convenient to transport and store, and it can also effectively prevent livestock from being picky eaters, ensuring a balanced intake of nutrients. Therefore, it has been widely used in modern animal husbandry.

[0003] In the operation of a traditional feed pellet mill, material typically falls vertically into the pelleting chamber from the top feed inlet. Inside the pelleting chamber, high-speed rotating pressure rollers force the material through numerous die holes on the ring die, thus extruding it into cylindrical pellets, which are then cut into predetermined lengths by a cutter. The quality of the final pellets, especially the uniformity of their density, hardness, and length, largely depends on the stability and uniformity of the extrusion process of the pressure rollers on the ring die.

[0004] However, in existing technologies, when material falls from the upper feed inlet, due to gravity and the material's own flow characteristics, it often concentrates in a localized area within the granulation chamber, rather than evenly covering the entire working surface of the ring die. This results in uneven material layer thickness during the rotation and compaction of the pressure rollers. In areas with thicker material accumulation, the extrusion pressure is too high, easily producing overheated and overly hard particles; while in areas with sparse material or even no coverage, effective extrusion cannot be achieved, resulting in loose particles or direct leakage of powder.

[0005] Uneven feeding directly leads to uneven extrusion, ultimately resulting in significant differences in the physical morphology and quality of feed pellets produced in the same batch, i.e., poor pellet uniformity. This not only affects the commercial value of feed products but also adversely impacts the precision feeding of poultry and livestock.

[0006] Therefore, this utility model proposes a feed pelleting device to improve pellet uniformity, thereby addressing the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above deficiencies, this utility model provides a feed pelleting device that improves pellet uniformity. It aims to address the problem in the prior art where uneven feeding in feed pelleting devices leads to uneven distribution of materials entering the pellet mill, which in turn affects the uniformity of the final feed pellets.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a feed pelleting device for improving pellet uniformity, comprising: a support frame, a support platform fixedly connected to the support frame, and a pellet mill installed below the support platform. The support platform has a through hole corresponding to the feed inlet of the pellet mill. The device further comprises a conveying chamber, a fixed frame, and a switch cover rotatably connected inside the fixed frame; a fixed shaft fixedly connected to the support platform, a baffle fixedly connected to the fixed shaft, and a plurality of equalizing grooves connected to the lower end of the baffle.

[0009] The baffle and the equalization tank together constitute a material dispersion assembly.

[0010] Furthermore, the output end of the conveying chamber is connected to the through hole on the support platform, the fixed frame is fixed on the support platform and covers the through hole to accommodate the switch cover, and the material dispersion assembly composed of the fixed shaft, baffle and equalization groove is arranged below the through hole and directly above the feed inlet of the pellet mill, forming a complete material path from material conveying to feeding control and then to forced uniform dispersion.

[0011] Preferably, a rotating shaft is rotatably connected inside the conveying cavity, a spiral fan blade is fixedly connected to the outer peripheral wall of the rotating shaft, and a motor for driving the rotating shaft to rotate is fixedly connected to the outside of the conveying cavity.

[0012] Preferably, a feeding hopper is provided at the top of the conveying cavity away from the through hole.

[0013] Preferably, a fixing block is also fixedly connected to the fixing frame, and a hydraulic rod for driving the opening and closing cover is installed on the fixing block.

[0014] Preferably, a lever is rotatably connected within the fixed frame, and the output end of the hydraulic rod is hinged to one end of the lever.

[0015] Preferably, the other end of the lever is fixedly connected to the rotating column via a connecting block.

[0016] Preferably, the rotating column is coaxially arranged with the switch cover, and a rotating block for driving the switch cover to rotate synchronously is fixedly connected to the rotating column.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art where materials fall directly into the pellet mill, resulting in uneven material distribution and poor particle uniformity. It achieves the effect of forcibly dispersing materials and ensuring that materials are evenly spread throughout the pellet mill inlet, thereby significantly improving the uniformity of the finished feed pellets.

[0018] 2. This utility model solves the problem of unstable material supply that may be caused by traditional manual feeding or intermittent feeding by setting up a spiral fan blade driven by a motor and a conveying chamber. It achieves the effect of automated, continuous and stable material conveying, and provides a reliable material guarantee for subsequent uniform feeding and efficient granulation.

Detailed Implementation

[0021] 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.

[0022] Reference Figures 1-4This utility model provides an embodiment of a feed pelleting device for improving pellet uniformity, comprising a support frame 1 and a support platform 2 fixedly connected to the support frame 1. The support frame 1 provides a stable mounting base for the entire device, and the support platform 2 supports various working components. A pellet mill 3 is installed below the support platform 2, and a through hole corresponding to the feed inlet of the pellet mill 3 is provided on the support platform 2 to connect the upper and lower spaces. The device also includes a conveying chamber 4, the output end of which is connected to the through hole of the support platform 2 for conveying material into the through hole. The device also includes a fixing frame 5 and a switch cover 505 rotatably connected inside the fixing frame 5. The fixing frame 5 is fixed to the support platform 2 and covers the through hole. The switch cover 505 is used to selectively open or close the through hole, thereby controlling the material feeding process. The core innovation of this embodiment is that the device supports the support platform 1. A material dispersion assembly is also installed on platform 2. The material dispersion assembly includes a fixed shaft 201, a baffle 202, and a distribution groove 203. The fixed shaft 201 is fixedly connected to the support platform 2, the baffle 202 is fixedly connected to the fixed shaft 201, and multiple distribution grooves 203 are connected to the lower end of the baffle 202. The material dispersion assembly is set below the through hole of the support platform 2 and directly above the feed inlet of the pellet mill 3. When the switch cover 505 is opened, the material falling from the through hole first impacts the baffle 202. The baffle 202 plays a preliminary buffering and forced dispersion role on the concentrated material flow. Subsequently, the dispersed material slides down the surface of the baffle 202 into multiple distribution grooves 203. The distribution grooves 203 act as guide channels to divide the material flow and guide it evenly to different areas of the feed inlet of the pellet mill 3, ensuring that the material entering the pellet mill 3 is evenly spread across the entire feed inlet cross section. A feeding hopper 401 for loading raw materials is provided at the top of the conveying chamber 4 and away from the through hole. A rotating shaft 404 is rotatably connected inside the conveying chamber 4. A spiral fan blade 403 is fixedly connected to the outer peripheral wall of the rotating shaft 404. A motor 402 is fixedly connected to the outside of the conveying chamber 4. The output shaft of the motor 402 is connected to one end of the rotating shaft 404. When the motor 402 is working, the output shaft of the motor 402 drives the rotating shaft 404 and the spiral fan blade 403 fixed on the rotating shaft 404 to rotate synchronously. This motor-driven spiral conveying structure can ensure that the material is continuously and stably pushed from the feeding hopper 401 to the output end of the conveying chamber 4, providing a reliable material supply basis for subsequent uniform feeding. To achieve precise driving and control of the switch cover 505, a fixing block 501 is fixedly connected to the fixing frame 5. A hydraulic rod 502 is mounted on the fixing block 501. The hydraulic rod 502 serves as a power source, providing driving force for the opening and closing of the switch cover 505. A lever 503 is rotatably connected inside the fixing frame 5. The output end of the hydraulic rod 502 is hinged to one end of the lever 503 via a pin, and the other end of the lever 503 is fixedly connected to the rotating column 506 via a connecting block 504. Furthermore, the rotating column 50... 6 is coaxially arranged with the switch cover 505, and a rotating block 507 is fixedly connected to the rotating column 506. The rotating block 507 is fixedly connected to the switch cover 505, thereby effectively transmitting the rotational torque of the rotating column 506 to the switch cover 505. This entire linkage mechanism, consisting of hydraulic rod 502, lever 503, connecting block 504, rotating column 506 and rotating block 507, can smoothly convert the linear motion of hydraulic rod 502 into the rotational motion of switch cover 505, thereby achieving reliable control of the material feeding channel.

[0023] Working principle: When granulation is required, external raw materials are loaded into the feeding hopper 401. Then, the motor 402 is started. The output shaft of the motor 402 drives the rotating shaft 404 in the conveying chamber 4 and the spiral fan blade 403 fixed on the rotating shaft 404 to rotate synchronously. The rotating spiral fan blade 403 stably pushes the material in the feeding hopper 401 along the conveying chamber 4 towards the through hole of the support platform 2, preparing for unloading.

[0024] When material needs to be unloaded, the hydraulic rod 502 extends after receiving the instruction. The output end of the hydraulic rod 502 pushes one end of the lever 503, causing the lever 503 to swing around its rotation fulcrum. The other end of the lever 503 drives the rotating column 506 to rotate through the connecting block 504. Since the rotating block 507 fixes the rotating column 506 to the switch cover 505, the rotation of the rotating column 506 ultimately drives the switch cover 505 to rotate around its own axis, thereby opening the through hole located below the conveying chamber 4, and the unloading process begins. After the switch cover 505 is opened, the material conveyed here falls downward through the through hole under the action of gravity. The material first impacts the baffle 202 set below. The concentrated material flow is forcibly dispersed and dispersed in all directions after being impacted by the baffle 202. Subsequently, the dispersed material slides down the inclined surface of the baffle 202 into the multiple equal distribution grooves 203 connected at the lower end. The equal distribution grooves 203 perform secondary division and regularization of the material flow, ensuring that the material can be evenly and extensively spread on the entire feed port section of the pellet mill 3. This makes the pressure rollers and molds inside the pellet mill 3 receive material evenly, and the consistency of the extruded granules in terms of size and density is significantly improved.
