Description

Technical Field

[0001] This utility model relates to the field of sorting technology, and in particular to a screening machine for feed processing. Background Technology

[0002] Feed is a general term for the food of animals raised by humans. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. Chinese utility model patent, authorized announcement number "CN220804255U", discloses a feed screening machine for feed processing. When the rotating motor is turned on, it drives the connecting shaft to rotate, which in turn drives the external drive shaft to rotate. When the drive shaft rotates, it drives several striking rods to rotate. When the striking rods rotate, they break up the clumps of feed, which improves the screening efficiency of the device.

[0003] While the above-mentioned technical solution can break up clumps of feed during use, it may also damage the original, well-shaped, and appropriately sized pellets. These normal pellets are prone to pulverization or breakage when subjected to mechanical impact, thereby altering the original structure and particle size distribution of the feed. The integrity and uniformity of feed pellets are crucial for animal digestion and absorption, as they directly affect feed utilization and animal growth performance. If feed pellets are excessively broken up, the nutritional value of the feed may be reduced, thus affecting the quality of feed production. Therefore, we propose a screening machine for feed processing. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a screening machine for feed processing. This machine can break up clumps of feed, but while breaking up clumps, it may also damage the original, intact, and appropriately sized pellets. These normal pellets are prone to pulverization or breakage when subjected to mechanical impact, thereby changing the original structure and particle size distribution of the feed. The integrity and uniformity of feed pellets are crucial for animal digestion and absorption, as they directly affect feed utilization and animal growth performance. If feed pellets are excessively broken up, the nutritional value of the feed may be reduced, thus affecting the quality of feed production.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a screening machine for feed processing, comprising:

[0027] Feed screening box 1, with a first conveyor belt 15 and a second conveyor belt 16 respectively installed inside the feed screening box 1;

[0028] The feed dispersing structure is located on the feed screening box 1.

[0029] The feed dispersing structure includes a dispersing shaft 4, multiple dispersing frames 13, a conveyor motor 3, a lifting cylinder 2, a partition plate 17, and a conveying screw 14. The lifting cylinder 2 is fixedly installed on one side of the feed screening box 1. The feed hopper and discharge pipe of the lifting cylinder 2 are both connected to the interior of the feed screening box 1. The feed hopper of the lifting cylinder 2 is in contact with the outer surface of the first conveyor belt 15. The conveyor motor 3 is fixedly installed on the top of the lifting cylinder 2. The output end of the conveyor motor 3 rotates and extends into the interior of the lifting cylinder 2 and is fixedly connected to the conveying screw 14. The conveying screw 14 is rotatably connected to the interior of the lifting cylinder 2. The partition plate 17 is fixedly connected to the interior of the feed screening box 1. The dispersing shaft 4 is rotatably connected to the interior of the feed screening box 1. The multiple dispersing frames 13 are all fixedly connected to the outer surface of the dispersing shaft 4.

[0030] Inside the feed screening box 1, two second conveyor rollers 9 and two first conveyor rollers 8 are rotatably connected. A second conveyor belt 16 is driven and sleeved on the outer surface of the two second conveyor rollers 9, and a first conveyor belt 15 is driven and sleeved on the outer surface of the two first conveyor rollers 8. A drive motor 5 is fixedly installed on one side of the feed screening box 1. The output end of the drive motor 5 extends rotatably into the interior of the feed screening box 1 and is fixedly connected to the corresponding second conveyor roller 9. The ends of the dispersing shaft 4, the two second conveyor rollers 9 and the two first conveyor rollers 8 away from the drive motor 5 all extend rotatably to the outside of the feed screening box 1. A first belt 10 is driven and sleeved on the outer surface of the second conveyor rollers 9 and the dispersing shaft 4 near the drive motor 5. The first belt 10 is located outside the feed screening box 1.

[0031] A third belt 12 is driven to the outer surface of the second conveyor roller 9 near the drive motor 5 and the corresponding first conveyor roller 8. Two eccentric rollers 6 are rotatably connected inside the feed screening box 1. The two eccentric rollers 6 are located inside the second conveyor belt 16 and the first conveyor belt 15, respectively. The ends of the two eccentric rollers 6 away from the drive motor 5 are rotatably extended to the outside of the feed screening box 1. The outer surface of the two eccentric rollers 6 is driven to the outer surface of the same third belt 12. A second belt 11 is driven to the outer surface of the first conveyor roller 8 near the drive motor 5 and the corresponding eccentric roller 6.

[0032] Two discharge ports 7 are provided on the side of the feed screening box 1 near the drive motor 5.

[0033] Furthermore, when using this device, the drive motor 5 is started by connecting an external power source. The drive motor 5 drives the corresponding second conveyor roller 9 to rotate. The rotation of the second conveyor roller 9 closest to the drive motor 5, in conjunction with another second conveyor roller 9, drives the second conveyor belt 16 to rotate. The rotation of the second conveyor roller 9 closest to the drive motor 5, in conjunction with the corresponding third belt 12, drives the corresponding first conveyor roller 8 to rotate. The rotation of the first conveyor roller 8 closest to the drive motor 5, in conjunction with another first conveyor roller 8, drives the first conveyor belt 15 to rotate. The rotation of the first conveyor roller 8 closest to the drive motor 5... Driven by the second belt 11, the corresponding eccentric roller 6 rotates. The rotation of the eccentric roller 6 near the first conveyor belt 15 will drive the eccentric roller 6 in the second conveyor belt 16 to rotate under the drive of the corresponding third belt 12, so that the two eccentric rollers 6 can rotate synchronously, which will facilitate the impact on the second conveyor belt 16 and the first conveyor belt 15, so that the feed is vibrated and screened when it is conveyed on the second conveyor belt 16 and the first conveyor belt 15. The rotation of the second conveyor roller 9 near the drive motor 5 will drive the dispersing shaft 4 to rotate through the first belt 10, and the dispersing shaft 4 will drive the multiple dispersing frames 13 to rotate.

[0034] Furthermore, when using this device, when the feed enters the feed screening box 1, it will fall onto the second conveyor belt 16 under the guidance of the partition plate 17, so that the first conveyor belt 15 and the second conveyor belt 16 can transport the feed. The qualified feed will be discharged from the discharge port 7 below the second conveyor belt 16 and the first conveyor belt 15, and the lumpy feed will be discharged into the lifting cylinder 2 from the feed hopper. By connecting to an external power source to start the conveyor motor 3, the conveyor motor 3 will drive the conveyor screw 14 to rotate, so that the conveyor screw 14 will discharge the lumpy feed back into the feed screening box 1, so that multiple dispersing frames 13 will break up the lumpy feed, thereby facilitating the subsequent screening of the broken feed.

[0035] With the cooperation of the lifting cylinder 2, conveying screw 14, dispersing frame 13, dispersing shaft 4, partition plate 17 and first belt 10, the clumped feed is discharged from the feed hopper of the lifting cylinder 2 into the lifting cylinder 2, so that the conveying screw 14 can discharge the clumped feed back into the feed screening box 1, and the multiple dispersing frames 13 can dissolve the clumped feed, so that the dissolved feed can be screened in subsequent processes, avoiding excessive crushing of the feed and further improving the production quality of the feed.

[0036] Working principle: When feed enters the feed screening box 1, it falls onto the second conveyor belt 16 under the guidance of the partition plate 17. This allows the first conveyor belt 15 and the second conveyor belt 16 to transport the feed. The qualified feed will be discharged from the discharge port 7 below the second conveyor belt 16 and the first conveyor belt 15. The lumpy feed will be discharged into the lifting cylinder 2 from the feed hopper. By connecting to an external power source and starting the conveyor motor 3, the conveyor motor 3 will drive the conveyor screw 14 to rotate, causing the conveyor screw 14 to discharge the lumpy feed back into the feed screening box 1. The multiple dispersing frames 13 will then break up the lumpy feed, making it easier for the broken feed to be screened in subsequent processes.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
