In a broad sense, feed can include food from various sources, such as plants, animals, and artificially synthesized substances. However, feed in a narrow sense mainly refers to the food of animals raised in agriculture or animal husbandry.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Feed, as a general term for the food of all raised animals, plays a vital role. It is not only related to the growth and development of animals, but also directly affects the health and breeding benefits of animals. In agriculture or animal husbandry, the type and quality of feed have a decisive influence on the feeding effect of animals. In a broad sense, feed can include food from various sources, such as plants, animals, and artificially synthesized substances. However, feed in a narrow sense mainly refers to the food of animals raised in agriculture or animal husbandry. These feed raw materials are of various types, including more than ten varieties such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, and feed additives. In general, as the basis of animal breeding, the type and quality of feed directly affect the growth and development of animals and the breeding benefits.

[0029] At present, the widely used pellet feed screening equipment mainly relies on dry screening technology, which uses the vibration of the screen or the blowing of airflow to remove foreign matter mixed in the feed particles. However, this method is not very effective in removing dust attached to the surface of the particles, so the feed needs to be cleaned for a second time. This step is essential to ensure the quality and safety of the feed. However, the secondary cleaning process undoubtedly increases the complexity and cost of the production process. At present, the pellet feed screening equipment widely used in feed production mainly adopts dry screening technology. This technology effectively removes foreign matter mixed in the feed particles, such as stones, metals and other impurities, by using the vibration of the screen or the blowing of airflow. This step is very important in the feed production process because it can ensure the quality and safety of the feed. However, although the dry screening technology performs well in removing large particle impurities, it is not very effective in removing dust attached to the surface of the particles. These tiny dust particles may pose a potential threat to the health of animals. For example, long-term intake of contaminated feed can weaken the immune system of animals, making them more susceptible to various diseases, increasing treatment costs and mortality. Decreased production performance: Contaminated feed can affect the growth, development and reproductive capacity of animals, leading to decreased production performance, such as reduced milk production and decreased meat quality. In particular, certain pollutants such as mycotoxins and heavy metals will accumulate in the animals' bodies, affecting not only animal health but also human health through the food chain.

[0030] Therefore, we urgently need to develop a new type of pellet feed screening device to reduce the reliance on secondary cleaning treatment, thereby improving production efficiency and reducing production costs.

[0031] See also Figure 1-Figure 9As shown, this embodiment provides a feed particle screening machine, including a body 1, which mainly protects its screening and cleaning devices, not only providing solid protection for the screening and cleaning process, but also ensuring the convenience and safety of operation. A cleaning box 4 is fixedly connected to the inner wall of the body 1, and the cleaning box 4 is used to soak the feed. When the feed is soaked, the water outlet 41 will spray a strong and uniform water flow to clean the surface of the feed. A foreign matter filter plate 13 is fixedly connected to the upper end of the inner wall of the cleaning box 4, and the foreign matter filter plate 13 is used to block some larger debris outside the cleaning box 4 to prevent some large particles of impurities from entering the cleaning box 4, thereby causing serious pollution to the water quality. This not only affects the cleaning effect, but also may bring inconvenience to subsequent processing and use. At the lower end of the side wall of the cleaning box 4, a water outlet pipe 41 is installed. This water outlet pipe 41 is not only used to replenish the water volume inside the cleaning box 4, but also can impact the surface of the feed to effectively remove attached impurities. On the other side of the cleaning box 4, away from the water outlet pipe 41, a cleaning plate 45 is fixedly connected. The cleaning plate 45 has a number of carefully designed holes inside, and each hole is equipped with a flexible brush. When the feed passes through these holes, the flexible brush will clean the surface of the feed again to ensure the purity of the feed. A water filter plate 46 is fixedly installed on the side wall of the cleaning plate 45, and its design purpose is to guide the water flow carrying the feed to flow downward. At the same time, an isolation net 47 is fixedly connected to the upper part of the water filter plate 46. The isolation net 47 allows part of the water flow to pass through, while effectively intercepting the feed in the water flow, thereby preventing the feed from entering the drainage column 413 with the water flow, ensuring the normal operation of the system. A fixedly connected water filter net 48 is provided on the side wall of the body 1. This water filter net 48 is intended to intercept the feed components in the water flow falling from the upper water filter plate 46, ensuring the effective separation of the feed and the water flow, so as to facilitate the subsequent processing of the feed.

[0032] A water storage box 44 is installed on the bottom wall of the body 1. The water storage box 44 is used to collect the water discharged from the cleaning box 4 above it and provide water to enter the cleaning box 4 again. The side wall of the water storage box 44 is equipped with a water inlet pipe 43. The corresponding ports of the water inlet pipe 43 and the water outlet pipe 41 are equipped with a circulation pump 42. The circulation pump 42 has an integrated filter element inside, which can effectively filter the water flow to ensure the purity of the water injected into the cleaning box 4 again, thereby avoiding secondary contamination of the feed. Below the water filter net 48, a special conveying component is provided, which is responsible for conveying the cleaned feed to the subsequent processing flow. The side wall of the body 1 is equipped with a power component to provide the power required for the conveying component to operate. This power comes from the flowing water of the cleaning box 4 above, which not only achieves environmental protection but also achieves energy-saving effects;

[0033] The conveying assembly includes a conveying platform 49, which is specially designed to provide an operating platform for the conveyor belt 410 to ensure the smooth progress of the work process. In order to ensure the stability and safety of the conveying platform 49 during operation, the two sides of the conveying platform 49 are fixedly connected to the bottom wall of the body 1 with support feet 411. In addition, the two ends of the conveying platform 49 are rotatably connected to the conveyor belt 410, and the conveyor belt 410 is responsible for transporting the feed to the next processing location. The end of the conveying platform 49 close to the water filter net 48 is rotatably connected to the first rotating shaft 415, and the first rotating shaft 415 is responsible for transmitting power to the conveying platform 49 to drive its normal operation;

[0034] The power assembly is equipped with a drainage column 413, whose internal structure has been planned to form a specific hollow structure to facilitate the smooth passage of water. The design feature of this hole is its geometric shape of being wide at the top and narrow at the bottom. When the water flows through this hole, it will gain acceleration at the outlet due to the change in shape, thereby enhancing the impact force of the water flow. The upper end of the drainage column 413 is closely connected to the inner wall of the body 1, and its position is set below the isolation net 47. In addition, the inner wall of the drainage column 413 is equipped with a runner blade 416. When the water flow from above hits the runner blade 416, it will cause it to rotate.

[0035] One end of the runner blade 416 penetrates the side wall of the drainage column 413 through a fixed connection and forms a stable connection with the third rotating shaft 418. The third rotating shaft 418 is designed to transmit the power generated by the rotation of the runner blade 416 to the second column gear 419, so as to cause it to rotate. The second column gear 419 is tightly combined with the end of the third rotating shaft 418 away from the runner blade 416 through a fixed connection. At the same time, the outer wall of the drainage column 413 is rotatably connected with the second rotating shaft 417, providing necessary support for the rotation of the first column gear 412. The end of the second rotating shaft 417 away from the drainage column 413 is tightly combined with the first column gear 412 through a fixed connection. The first column gear 412 and the outer wall of the second column gear 419 are meshed with each other, ensuring that the second column gear 419 can drive the first column gear 412 to rotate when rotating. This design enables the rotation of the first column gear 412 to further cause the second rotating shaft 417 to rotate. In addition, the outer wall of the second rotating shaft 417 and the first rotating shaft 415 are rotatably connected with the second belt 414. When the second rotating shaft 417 rotates, it drives the second belt 414 to rotate, and then drives the first rotating shaft 415 to rotate through the second belt 414. Finally, the rotation of the first rotating shaft 415 drives the conveying platform 49 to rotate.

[0036] The improvement of this embodiment is that:

[0037] First, the feed will be introduced into the inner space of the cleaning box 4. Here, clean water will continue to flush the surface of the feed to effectively remove attached dust and other impurities. Afterwards, the feed will pass through the holes inside the cleaning plate 45 again, where special brushes are distributed to deeply scrub the surface of the feed, thereby ensuring that the purity of the surface of the feed reaches a certain standard. This series of cleaning processes can ensure the cleanliness of the surface of the feed, which not only extends the shelf life of the feed, but also provides health and safety guarantees for animal consumption. In addition, this cleaning method can also effectively reduce the risk of diseases caused by unclean feed, and the water used in the cleaning process is recycled, which not only saves precious water resources, but also ensures efficient cleaning while achieving the goal of low carbon and environmental protection.

[0038] Considering the influence of residual moisture on the surface of feed after cleaning and its subsequent screening work, we must first recognize the adverse effect of residual moisture on feed fluidity. When the surface of feed contains too much moisture, the friction between particles will increase, resulting in reduced fluidity. This situation may cause the problem of feed blockage during screening, thereby reducing screening efficiency. Secondly, residual moisture will also affect the accuracy of screening. The moisture content in the feed is closely related to the bonding force between particles. When the moisture content is too high, the bonding force between particles will increase, which may cause the feed particles to be unable to pass through the screen, thereby affecting the accuracy of screening. In addition, residual moisture may also cause the expansion and deformation of feed particles, which will have a further negative impact on the screening effect. Therefore, a drying box 3 is installed on one side of the body 1, which is specially used for drying feed to ensure the smooth progress of subsequent processing. The side wall of the drying box 3 is designed with a first discharge port 31 and a second discharge port 32, and the first discharge port 31 is located above the second discharge port 32. Among them, the first discharge port 31 is responsible for discharging larger particles of feed, while the second discharge port 32 is used to discharge feed screened by the screening plate 313. A plurality of heating tubes 33 are installed at the upper end of the drying box 3 to provide a uniform heating environment. A screening plate 313 is installed on the side wall of the drying box 3, which can be shaken up and down by rotation to improve the screening effect. A bearing plate 314 is fixedly connected to the side wall of the drying box 3, and the bearing plate 314 is located directly below the screening plate 313. A transmission assembly is provided on the side wall of the drying box 3, and the transmission assembly is used to drive the screen plate 313 to shake. The transmission assembly includes a turntable 37, and the turntable 37 is fixedly connected to a rotating rod 36. The end of the rotating rod 36 away from the turntable 37 is rotatably connected to the side wall of the drying box 3. The end of the conveying platform 49 close to the drying box 3 is fixedly connected to the second transmission rod 34. The outer side of the second transmission rod 34 is fixedly connected to the second transmission rod 34. The first belt 35 is connected to the outer wall of the rotating rod 36 for rotation together, the rotating disk 37 is fixedly connected to a fixed round rod 39 at the eccentric part, the outer wall of the fixed round rod 39 is sleeved with a collar 38, the side wall of the drying box 3 is fixedly connected to a first slide rail 311, the inner wall of the first slide rail 311 is slidably connected to a first slide bar 312, the upper end of the first slide bar 312 is connected to the outer wall of the collar 38 for rotation together with a linkage rod 310, and the end of the first slide bar 312 away from the rotating disk 37 is rotatably connected to the side wall of the screening plate 313

[0039] Considering that a large amount of feed enters the body 1, it may cause blockage at the entrance of the body 1. Therefore, a support rod 2 is installed on the inner wall of the body 1. The support rod 2 is responsible for transferring the gravity borne by the support frame 21 to the body 1, thereby enhancing the stability of the overall structure. The upper end of the support rod 2 is connected to two support frames 21. The main function of these two support frames 21 is to support the motor 22 and ensure the normal operation of the motor 22. The opposite sides of the two support frames 21 are connected to the motor 22, and the motor 22 provides power for the feeding rod 24. The output end of the motor 22 is connected to the first transmission rod 23, and the end of the first transmission rod 23 away from the motor 22 is connected to the feeding rod 24. The side wall of the body 1 is equipped with a guide plate 12, which is vertically located just below the feeding rod 24 to ensure that the feed can quickly and accurately enter the inside of the cleaning box 4.

[0040] When the feed particle screening machine of the utility model is used, the staff starts the motor 22 and the circulating pump 42, and the motor 22 drives the feeding rod 24 to rotate, and then pours the feed into the machine body 1. Under the stirring of the feeding rod 24, the feed enters the cleaning box 4, and the water flow rinses its surface. The cleaned feed is then cleaned by the cleaning plate 45, and then falls above the water filter 48 through the water filter plate 46. At the same time, the water flows into the drainage column 413 through the isolation net 47, impacts the runner blade 416 to rotate, and then drives the third rotating shaft 418, the second column gear 419, the first column gear 412, the second rotating shaft 417 and the first rotating shaft 415 to rotate. Finally, the rotation of the first rotating shaft 415 drives the conveying platform 49 and the conveyor belt 410 to move, and transports the feed to the drying box 3 for drying. The dried feed falls into the screening plate 313, and the rotation of the second transmission rod 34 drives the first belt 35 to rotate, and then drives the rotating rod 36 and the rotating disk 37 to rotate. The rotation of the turntable 37 drives the first slide bar 312 to move up and down through the fixed round rod 39 and the linkage rod 310, thereby driving the screening plate 313 to vibrate.
