Description

Technical Field

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

[0002] Concentrated feed is a feed product made by mixing protein feed, mineral feed, and additive premixes in a certain proportion, also known as "protein supplement." It cannot be fed directly to animals; it must be mixed with energy feeds (such as corn, wheat bran, etc.) in a specified ratio to form a nutritionally complete compound feed. During feed production, a pelleting process is required, and concentrated feed pelleting equipment is a specialized device that processes concentrated feed (a mixture of protein, minerals, and additives) into pelleted feed. Pelleted feed has advantages such as good palatability, ease of storage and transportation, and reduced feed waste, and is widely used in the livestock and poultry farming industry.

[0003] However, existing technologies still have the following problems:

[0004] With the large-scale development of modern animal husbandry, the demand for concentrated feed is increasing. The performance of pelleting equipment directly affects the quality and efficiency of feed production. In actual production, existing concentrated feed pelleting devices mostly use single pressure rollers or simple extrusion structures. The material is subjected to uneven force when passing through the ring die, resulting in a slow extrusion process and easy material accumulation and blockage. Existing devices generally lack precise quantitative feeding mechanisms and rely heavily on manual feeding, which cannot ensure that the material enters the pelleting chamber evenly and stably. Uneven feeding will cause excessive pressure in some areas during the extrusion process, while the pressure in other areas is insufficient, further affecting the pellet forming effect and production efficiency. Utility Model Content

[0005] In order to solve the problems of low pelleting efficiency and inconvenient feeding, the purpose of this utility model is to provide a concentrated feed pelleting device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a concentrated feed pelleting device, comprising a first support, a second support fixedly installed on one side of the first support, a pelleting device fixedly installed on the upper surface of the first support, a conveying device fixedly installed on the upper surface of the second support, the pelleting device comprising a pelleting shell, a flip cover rotatably connected to the upper surface of the pelleting shell, a rotating shaft rotatably installed on the upper surface of the first support, a driven synchronous pulley and a turntable respectively fixedly sleeved at both ends of the rotating shaft, a first motor fixedly installed on one side of the upper surface of the first support, a driving synchronous pulley fixedly sleeved at the output end of the first motor, a synchronous belt jointly sleeved on the outer surfaces of the driving synchronous pulley and the driven synchronous pulley, a ring die fixedly installed between the inner walls of the pelleting shell, a plurality of pressure rollers fixedly connected to one side of the turntable, a plurality of scrapers fixedly sleeved on the outer surfaces of the plurality of pressure rollers, and the plurality of pressure rollers and the plurality of scrapers are all located inside the ring die.

[0007] Preferably, the conveying device includes a trough, the lower surface of which is fixedly connected to a second support, a spiral shaft is rotatably connected inside the trough, a second motor is fixedly installed at the end of the trough, the output end of the second motor is fixedly connected to the spiral shaft, a feed inlet is provided on one side of the upper surface of the trough, and a discharge outlet is provided on one side of the lower surface of the trough.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This invention utilizes a conveying device and a granulation device in synergy. A synchronous belt drives the driven synchronous pulley and shaft to rotate, achieving stable rotation of the turntable and pressure rollers. As multiple pressure rollers rotate with the turntable, the scraper quickly and evenly pushes the material inside the granulation shell to the inner wall of the ring die, preventing localized material accumulation. The scraper maintains a certain gap with the inner surface of the ring die, ensuring that the material is fully squeezed through the die holes. Simultaneously, during material pushing, residual material around the die holes is promptly cleaned. The spiral conveying structure in the conveying device enables quantitative and continuous material transport, avoiding the unevenness of manual feeding. Furthermore, the stirring action of the blades allows for initial mixing of the raw materials during transport, improving the uniformity of subsequent granulation. Attached Figure Description

[0015] 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.

[0016] Example: Figure 1-3 As shown, this utility model provides a concentrated feed pelleting device, including a first support 11. A second support 12 for supporting a feeding mechanism is fixedly installed on one side of the first support 11, and a pelleting device 13 is fixedly installed on its upper surface. A conveying device 14 is fixedly installed on the upper surface of the second support 12. The conveying device 14 includes a trough 30, the lower surface of which is fixedly connected to the second support 12. A spiral shaft 29 is rotatably connected inside the trough 30, and a second motor 31 is fixedly installed at its end. The output end of the second motor 31 is fixedly connected to the spiral shaft 29. A feed inlet 32 ​​is opened on one side of the upper surface of the trough 30, and a discharge outlet 33 is opened on one side of the lower surface. A continuously spiral conveying blade is sleeved on the outer surface of the spiral shaft 29. The material is pushed from the feed inlet 32 ​​to the discharge outlet 33 at a uniform speed by rotating, avoiding material accumulation and blockage. The material enters the trough 30 from the feed inlet 32. The second motor 31 drives the spiral shaft 29 to rotate, and the material is conveyed from the discharge outlet 33 to the feeding port 18 of the pelleting shell 16 by the continuous spiral blades. The uniform and stable feeding avoids the problem of blockage.

[0017] The pelletizing device 13 includes a pelletizing shell 16, the lower material receiving area of ​​which is set at an inclined angle to guide the shaped pellets out by gravity. A flip cover 17 is rotatably connected to the upper surface. A rotating handle is fixedly installed on the outer surface of the flip cover 17 for easy opening to clean the interior or replace the mold. A feeding port 18 is opened on one side of the outer surface. One end of the feeding port 18 is connected to the discharge port 33 of the conveying device 14 to receive materials. The rotating shaft 20 is rotatably mounted on the upper surface of the first support 11 through a bearing seat. The driven synchronous pulley 21 and the turntable 22 are fixedly sleeved at both ends, respectively. The first motor 26 is fixed on the upper surface of one side of the first support 11. The output end is sleeved with the driving synchronous pulley 27. The driving synchronous pulley 27 and the driven synchronous pulley 21 are connected by a synchronous belt 28 to drive the rotating shaft 20 and the turntable 22 to rotate.

[0018] The ring die 23 is fixed between the inner walls of the granulation shell 16 and has multiple uniformly distributed die holes on its outer surface. As the core die for material extrusion molding, multiple pressure rollers 24 are arranged in a ring array and fixed on one side of the turntable 22. They rotate around the ring die 23 with the turntable 22. At the same time, due to friction, cutting and pushing with the inner wall of the ring die 23, a wedge-shaped extrusion space is formed with the ring die 23.

[0019] Multiple scrapers 25 are fixedly sleeved on the outer surface of the pressure roller 24 at equal intervals, with one end maintaining a certain gap with the inner surface of the ring die 23. As the pressure roller 24 rotates, they can scrape the inner wall of the ring die 23 to remove adhering materials, push loose materials to the extrusion area, and trim the ends of the granules in the extrusion die. The first motor 26 drives the rotating shaft 20 and the turntable 22 to rotate through the synchronous belt 28. The pressure roller 24 rotates with the turntable 22, squeezing the material through the die hole of the ring die 23. The ring array of pressure rollers 24 increases the extrusion area and improves granulation efficiency. The scrapers 25 continuously clean the inner wall of the ring die 23 and push the material to ensure uniform feeding. At the same time, they trim the shape of the granules. The formed granules are thrown towards the inclined inner wall of the granulation shell 16 by the centrifugal force of the rotating ring die 23 and slide down the wall to the discharge port 19 for discharge. The inclined structure reduces material retention and improves the smoothness of discharge.

[0020] Working principle: Material enters the trough 30 through the feed inlet 32 ​​of the conveying device 14. The second motor 31 drives the spiral shaft 29 to rotate, and the spiral blades on the spiral shaft 29 push the material to move within the trough 30 and output it from the discharge port 33. Due to the continuous spiral blade design of the spiral shaft 29, the material can be stably and evenly conveyed to the next stage, avoiding material blockage and controlling the discharge amount. The material coming out of the discharge port 33 enters the interior of the granulation device 13 through the connection channel with the feeding port 18 on the granulation shell 16 in the granulation device 13.

[0021] The first motor 26 starts, and its output end's active synchronous pulley 27 rotates, driving the driven synchronous pulley 21 via the synchronous belt 28. The driven synchronous pulley 21 is fixed to the rotating shaft 20, causing the rotating shaft 20 to rotate. The turntables 22 fixed at both ends of the rotating shaft 20 also rotate accordingly. The turntables 22 drive the pressure roller 24 to rotate around the ring die 23. Multiple scrapers 25, which are sleeved on the outer surface of the pressure roller 24, move in a circular motion. There is a certain gap between the scrapers 25 and the inner surface of the ring die 23. During the rotation, the scrapers 25 continuously scrape the inner surface of the ring die 23 and cut the material, while applying a certain pushing force to the material. The material entering the granulation shell 16 is squeezed between the pressure roller 24 and the ring die 23. The surface of the ring die 23 has uniformly distributed die holes. The material is squeezed through the die holes and initially formed into granules. The scraper 25 is fixed to the outside of the pressure roller 24 and rotates with the pressure roller 24. It can scrape off excess material from the inner wall of the ring die 23, ensuring uniform feeding and improving granulation quality. After the formed granules are extruded from the die holes of the ring die 23, they are discharged from the granulation device through the discharge port 19 inclined at the bottom of the granulation shell 16, completing the granulation process of concentrated feed. Throughout the process, all components work together to achieve continuous operation from material conveying to granulation and discharge.

[0022] 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 the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
