Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a pellet screening device for feed processing that is easy to use. Background Technology

[0002] Feed processing is the process of transforming various feed ingredients into products suitable for livestock and poultry. First, the raw materials must be pre-treated, such as cleaned, impurities removed, and crushed, turning large particles into smaller ones to facilitate subsequent processing and animal digestion. Then, based on the different nutritional needs and growth stages of various animals, precise formulations are made according to scientific principles. Feed processing screening devices are crucial equipment in the feed production process, used to screen feed particles. These devices effectively remove particles that do not meet specifications, ensuring uniform particle size and quality stability of feed products, thus improving feed quality and playing a key role in the feed processing industry.

[0003] However, most existing feed processing screening devices suffer from poor screening effect and easy accumulation and clogging of the screen by materials, resulting in a significant reduction in screening efficiency. This not only delays the production schedule but also requires frequent cleaning and maintenance, increasing labor costs. Furthermore, untimely cleaning may cause material deterioration, further affecting feed quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor screening effect and easy accumulation and clogging of the screen in most existing feed processing screening devices, which greatly reduces screening efficiency, delays production progress, requires frequent cleaning and maintenance, increases labor costs, and may cause material deterioration due to untimely cleaning, further affecting feed quality. Therefore, this invention proposes an easy-to-use pellet screening device for feed processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a user-friendly pellet screening device for feed processing, comprising a body and a screening device. The upper surface of the body has a feed inlet, and the lower surface of the body has a discharge outlet. The screening device is disposed within the inner wall of the body and includes a screening plate inserted into the body. A through hole is provided on one side of the body, and a push rod is slidably connected to the inner wall of the through hole. A hole is provided on the side of the push rod near the screening plate, and a crossbar is slidably connected to the inner wall of the hole. A scraper is fixedly connected to the surface of the crossbar. The lower surface of the scraper is rotatably connected to rollers. By setting up a screening device, the multi-stage screening plates filter layer by layer, greatly improving the screening fineness and accurately separating materials of different particle sizes to ensure the quality of feed products. Secondly, the inclined screening plates, combined with gravity, allow the materials to roll naturally, reducing accumulation and lowering the risk of blockage from the source. The reciprocating motion of the cylinder-driven scraper and push rod further disperses the accumulated materials, effectively reducing screen blockage and maintaining screening efficiency. Finally, the removable screening plate design is convenient and quick. It can be easily removed by pulling out the pin and pulling the handle, which is convenient for cleaning unqualified materials and daily maintenance, improving the convenience and flexibility of equipment use.

[0006] Preferably, the screening plate is inclined, and the roller abuts against the screening plate. By setting the screening plate, the material is filtered layer by layer, which can more accurately separate materials of different particle sizes, achieve the purpose of fine screening, ensure that the particle size of the feed product meets the requirements, and improve product quality.

[0007] Preferably, a return spring is sleeved on the surface of the crossbar. The two ends of the return spring are fixedly connected to the push rod and the scraper, respectively. By setting the return spring, when the roller moves on the screening plate, it will squeeze the crossbar and cause the return spring to contract. When the push rod is reset, the return spring generates elastic force to squeeze the crossbar to reset. This process can ensure that the roller is always in contact with the screening plate.

[0008] Preferably, there are three screening plates, and the three screening plates are arranged in a linear array.

[0009] Preferably, a cylinder is fixedly connected to one side of the machine body, and a telescopic rod is fixedly connected to the driving end of the cylinder. By setting the cylinder, the cylinder drives the telescopic rod to reciprocate, the telescopic rod drives the push rod to move, and the push rod drives the scraper and roller to move along the screening plate.

[0010] Preferably, the end of the telescopic rod away from the cylinder is fixedly connected to the push rod, and the end of the screening plate away from the push rod is fixedly connected to a handle. By setting the telescopic rod, the power generated by the cylinder can be effectively transmitted. After the cylinder is started, the movement of its piston is transmitted to the push rod through the telescopic rod, so that the push rod can move accordingly according to the drive of the cylinder, thereby driving the scraper and roller to move along the screening plate, realizing the functions of pushing materials, preventing blockage, and re-screening.

[0011] Preferably, the surface of the handle has a second hole, and a pin is inserted into the side of the machine body near the handle. The pin is inserted into the second hole on the surface of the handle. By setting the pin, the pin can fix the screening plate to the machine body, ensuring that the screening plate maintains a stable position during the screening process and will not be displaced or shaken due to the impact of materials, the vibration of the cylinder or other external forces.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, during use, the material is poured into the machine body through the feed port, and then the cylinder is activated. The material falls onto the screening plates, which have three layers. The material passes through the three screening plates and is finally discharged through the discharge port. This multi-stage filtration facilitates fine screening. At the same time, because the screening plates are inclined, the material is affected by gravity and rolls towards the scraper, preventing material accumulation. The cylinder drives the telescopic rod to drive the push rod to reciprocate continuously, causing the scraper and roller to push the accumulated material along the screening plate for screening again, reducing blockage and loosening the material. When the roller moves on the screening plate, it presses against the crossbar. The crossbar slides and the return spring contracts. When the push rod returns to its original position, the return spring generates elastic force to press the crossbar back to its original position, ensuring that the roller always abuts against the screening plate, facilitating the pushing of the material. After screening is completed, the pin is pulled out, and then the handle is pulled to remove the screening plate. The unqualified material screened on the screening plate falls off and is discharged through the discharge port.

[0014] By incorporating this utility model, the multi-stage screening plates achieve layer-by-layer filtration, significantly improving screening precision and enabling accurate separation of materials of different particle sizes, thus ensuring the quality of feed products. Secondly, the inclined screening plates, combined with gravity, allow materials to roll naturally, reducing accumulation and mitigating the risk of blockage at the source. The reciprocating motion of the cylinder-driven scraper and push rod further disperses accumulated materials, effectively reducing screen blockage and maintaining screening efficiency. Finally, the removable screening plate design is convenient and quick; simply pull out the pin and drag the handle to easily remove it, facilitating the cleaning of substandard materials and routine maintenance, thereby improving the convenience and flexibility of equipment use.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a pellet screening device for easy-to-use feed processing, including a body 1 and a screening device 4. The upper surface of the body 1 is provided with a feeding port 2, the lower surface of the body 1 is provided with a discharge port 3, and the screening device 4 is disposed in the inner wall of the body 1.

[0022] In this embodiment: the screening device 4 includes a screening plate 41, which is inserted into the machine body 1. A through hole is provided on one side of the machine body 1, and a push rod 42 is slidably connected to the inner wall of the through hole on one side of the machine body 1. A hole is provided on the side of the push rod 42 near the screening plate 41, and a crossbar 47 is slidably connected to the inner wall of the hole on the surface of the push rod 42. A scraper 45 is fixedly connected to the surface of the crossbar 47, and a roller 46 is rotatably connected to the lower surface of the scraper 45. By setting up the screening device 4, the multi-stage screening plates 41 filter layer by layer, greatly improving the screening fineness. It can accurately separate materials of different particle sizes, ensuring the quality of feed products. Secondly, the inclined screening plate 41, combined with gravity, allows the material to roll naturally, reducing accumulation and lowering the risk of blockage from the source. The reciprocating motion of the scraper 45 and push rod 42 driven by the cylinder 44 further disperses the accumulated material, effectively reducing screen blockage and maintaining screening efficiency. Finally, the removable screening plate 41 is designed for convenience and quick removal. It can be easily removed by pulling out the pin 410 and pulling the handle 49, which facilitates the cleaning of unqualified materials and daily maintenance, improving the convenience and flexibility of equipment use.

[0023] Specifically, the screening plate 41 is inclined, and the roller 46 abuts against the screening plate 41. By setting the screening plate 41, the material is filtered layer by layer, which can more accurately separate materials of different particle sizes, achieve the purpose of fine screening, ensure that the particle size of the feed product meets the requirements, and improve product quality.

[0024] Specifically, a return spring 48 is fitted on the surface of the crossbar 47. The two ends of the return spring 48 are fixedly connected to the push rod 42 and the scraper 45, respectively. By setting the return spring 48, when the roller 46 moves on the screening plate 41, it will squeeze the crossbar 47 to cause the return spring 48 to contract. When the push rod 42 is reset, the return spring 48 generates elastic force to squeeze the crossbar 47 to reset. This process can ensure that the roller 46 always abuts against the screening plate 41.

[0025] Specifically, there are three screening plates 41, which are arranged in a linear array.

[0026] Specifically, a cylinder 44 is fixedly connected to one side of the machine body 1, and a telescopic rod 43 is fixedly connected to the drive end of the cylinder 44. By setting the cylinder 44, the cylinder 44 drives the telescopic rod 43 to reciprocate. The telescopic rod 43 drives the push rod 42 to move, and the push rod 42 drives the scraper 45 and the roller 46 to move along the screening plate 41.

[0027] Specifically, the end of the telescopic rod 43 away from the cylinder 44 is fixedly connected to the push rod 42, and a handle 49 is fixedly connected to one end of the screening plate 41.

[0028] In this embodiment: by setting the telescopic rod 43, the power generated by the cylinder 44 can be effectively transmitted. After the cylinder 44 is started, the movement of its piston is transmitted to the push rod 42 through the telescopic rod 43, so that the push rod 42 can move accordingly according to the drive of the cylinder 44, thereby driving the scraper 45 and the roller 46 to move along the screening plate 41, realizing the functions of pushing materials, preventing blockage and re-screening.

[0029] Specifically, a second hole is provided on the surface of the grip 49, and a pin 410 is inserted into the side of the body 1 near the grip 49. The pin 410 is inserted into the second hole on the surface of the grip 49.

[0030] In this embodiment: by setting a pin 410, the pin 410 can fix the screening plate 41 on the machine body 1, ensuring that the screening plate 41 maintains a stable position during the screening process and will not be displaced or shaken due to the impact of materials, the vibration of cylinder 44 or other external forces.

[0031] Working Principle: During operation, material is poured into the machine body 1 through the feed inlet 2. Then, the cylinder 44 is activated, causing the material to fall onto the screening plates 41. There are three screening plates 41. The material passes through these three plates and is finally discharged through the outlet 3. This multi-stage filtration facilitates fine screening. Simultaneously, because the screening plates 41 are inclined, the material is affected by gravity and rolls towards the scraper 45, preventing material accumulation. The cylinder 44 drives the telescopic rod 43, which in turn drives the push rod 42 in a continuous reciprocating motion. This causes the scraper 45 and roller 46 to push the accumulated material along the screening plates 41 for further screening, reducing blockage and loosening the material. As the roller 46 moves on the screening plates 41, it presses against the crossbar 47. The crossbar 47 slides back, and the return spring 48 retracts. When the push rod 42 returns to its original position, the return spring 48 generates elastic force to press the crossbar 47 back to its original position, ensuring that the roller 46 remains in contact with the screening plate. The plates 41 abut against each other, facilitating the movement of materials. After screening, the pin 410 is pulled out, and the handle 49 is pulled to remove the screening plate 41. The unqualified materials screened on the screening plate 41 fall off and are discharged through the discharge port 3. By setting up this utility model, the multi-stage screening plates 41 filter layer by layer, greatly improving the screening fineness and accurately separating materials of different particle sizes, ensuring the quality of feed products. Secondly, the inclined screening plates 41, combined with gravity, allow the materials to roll naturally, reducing accumulation and reducing the risk of blockage from the source. The scraper 45 and push rod 42 driven by the cylinder 44 reciprocate, further dispersing the accumulated materials, effectively reducing screen blockage and maintaining screening efficiency. Finally, the removable screening plate 41 is designed for convenience and quick removal. Pulling out the pin 410 and pulling the handle 49 makes it easy to remove, facilitating the cleaning of unqualified materials and daily maintenance, improving the convenience and flexibility of equipment use.
