Abstract
Description
Technical Field
[0001] This utility model relates to the field of forage processing technology, specifically a forage screening and filtration device. Background Technology
[0002] In livestock production, forage grass is the main source of feed for livestock, and its quality directly affects animal health and breeding efficiency. Therefore, screening and filtering forage grass has become a key link in ensuring feed quality. During the harvesting, drying and transportation of forage grass, impurities such as soil, stones, weeds and metal fragments will inevitably be mixed in.
[0003] In existing technology, such as the Chinese announcement number CN221046564U, a rolling cleaning sieve for forage seeds includes a base and a sealing cover. Hydraulic rods are symmetrically installed on both sides of the bottom of the base, and a bearing plate is rotatably connected to the top of each hydraulic rod. Several sets of support rings are evenly installed on the top surface of the bearing plate. This invention uses a screening mesh. When the cleaning sieve cylinder rotates, the forage seeds inside will tumble. Smaller forage seeds will fall outwards through the mesh holes, while larger impurities will remain in the center. Through continuous rotation, the forage seeds, after impurities have been removed, will undergo further screening, thus classifying the forage seeds according to size for convenient subsequent processing and use. This provides the advantage of multi-stage screening.
[0004] Although the above-mentioned technical solutions have the above-mentioned technical advantages, their disadvantages are that when processing forage mixed with various impurities, the forage is easy to get tangled with the impurities and accumulate on the screen surface or screen holes, resulting in frequent jamming problems. Once jamming occurs, it not only seriously reduces the screening efficiency, but also requires frequent manual shutdowns for cleaning, increasing labor intensity and maintenance costs. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a forage screening and filtering device, which solves the problem of material easily getting stuck on the screen surface or screen holes.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a forage screening and filtering device, comprising a protective shell, a feed hopper fixedly connected to the outer side of the protective shell, and support legs fixedly connected around the perimeter of the protective shell; further comprising a screening assembly, the outer side of which is fixedly connected to the inner side of the protective shell; the screening assembly includes a screen cylinder, a fixed ring rotatably connected to the outer side of the screen cylinder, a support roller rotatably connected to the inner wall of the fixed ring, drive teeth fixedly connected to both sides of the support roller, toothed rings fixedly connected to both sides of the screen cylinder, an arc-shaped feeding plate fixedly connected to the inner side of the screen cylinder, and a striking component fixedly connected to the outer side of the support roller; the arc-shaped feeding plate on the inner side of the screen cylinder rotates with the screen cylinder, its shape being spiral, and can simultaneously convey feed to the side of the screen cylinder away from the feed hopper for discharge while the screen cylinder rotates and screens;
[0007] The striking component includes a fixed sleeve, a rotating shaft is rotatably connected to the outer side of the fixed sleeve, and arc-shaped connecting rods are fixedly connected to both sides of the rotating shaft. A striking block is rotatably connected to the outer side of the arc-shaped connecting rod. Through continuous striking, the screen holes of the screen cylinder can be effectively prevented from clogging, ensuring screening efficiency and causing the pasture particles and impurities adhering to the inner side of the screen cylinder or clogging the screen holes to fall off and complete the screening.
[0008] Preferably, the inner wall of the protective shell is fixedly connected to the outer side of the fixing ring, and the fixing ring is symmetrically arranged along both sides of the protective shell. While supporting the screen cylinder, the fixing ring can also separate the toothed ring and the drive tooth from the screening part of the screen cylinder, ensuring the stability of the device during operation.
[0009] Preferably, the support rollers are arranged in a ring along the outer side of the toothed ring, the drive teeth mesh with the toothed ring, and the bottom end of the feed hopper extends into the interior of the screen cylinder. When the motor drives the support rollers to rotate, the drive teeth drive the toothed ring, thereby causing the screen cylinder to rotate around its own axis.
[0010] Preferably, the striking components are arranged linearly along the outer side of the support roller, and the outer wall of the support roller is fixedly connected to the inner wall of the fixed sleeve. When the support roller rotates, it drives the fixed sleeve and the rotating shaft to move together.
[0011] Preferably, a torsion spring is fixedly connected to the inner side of the rotating shaft, and the end of the torsion spring away from the rotating shaft is fixedly connected to the outer side of the fixed sleeve. Under centrifugal force, the arc-shaped connecting rod can drive the rotating shaft to deflect relative to the fixed sleeve, at which time the torsion spring is torn by force.
[0012] Preferably, the rotating shaft is arranged in a ring along the outer side of the fixed sleeve, and the outer side of the striking block is in contact with the outer side of the screen cylinder. The striking block can contact the surface of the screen cylinder and generate striking force during rotation.
[0013] This utility model provides a forage screening and filtering device. It has the following beneficial effects:
[0014] (i) The device is equipped with a screening component. The screen cylinder rotates around its own axis. At this time, small particles of impurities mixed in with the feed will fall down along the holes opened on the surface of the screen cylinder and finally be discharged from the bottom of the protective shell. During this process, the arc-shaped feeding plate on the inner side of the screen cylinder rotates with the screen cylinder. Its shape is spiral. While the screen cylinder rotates and screens, the feed can be transported to the side of the screen cylinder away from the feed hopper to complete the discharge. Thus, the feeding process can be completed at the same time as screening.
[0015] (ii) The device is equipped with a striking component. When the support roller rotates, it drives the fixed sleeve and the rotating shaft to move together. At this time, under the centrifugal force, the arc-shaped connecting rod drives the rotating shaft to deflect relative to the fixed sleeve. At this time, the torsion spring is twisted by force, and the striking block can contact the surface of the screen cylinder and generate striking force during the rotation. Through continuous striking, the screen hole of the screen cylinder can be effectively prevented from being blocked, ensuring the screening efficiency and causing the pasture particles and impurities that are adhered to the inside of the screen cylinder or blocking the screen hole to fall off and complete the screening.

[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] Example: Please refer to Figure 1-4This utility model provides a technical solution: a forage screening and filtering device, including a protective shell 1, a feed hopper 2 fixedly connected to the outer side of the protective shell 1, the inclined design of the bottom of the feed hopper 2 facilitates the smooth guidance of forage into the screen cylinder 41, support legs 3 fixedly connected around the protective shell 1, and also includes: a screening component 4, the outer side of the screening component 4 is fixedly connected to the inner side of the protective shell 1; forage can enter the interior of the screening component 4 through the feed hopper 2.
[0023] The screening assembly 4 includes a screen cylinder 41. A fixing ring 43 is rotatably connected to the outer side of the screen cylinder 41. The fixing ring 43 supports the screen cylinder 41 and also separates the toothed ring 42 and the drive teeth 45 from the screening part of the screen cylinder 41, ensuring the stability of the device during operation. A support roller 44 is rotatably connected to the inner wall of the fixing ring 43. Drive teeth 45 are fixedly connected to both sides of the support roller 44. A toothed ring 42 is fixedly connected to both sides of the screen cylinder 41. An arc-shaped feeding plate 46 is fixedly connected to the inner side of the screen cylinder 41. A striking component 47 is fixedly connected to the outer side of the support roller 44. The inner wall of the protective shell 1 is fixedly connected to the outer side of the fixing ring 43, and the fixing ring 43 is symmetrically arranged along both sides of the protective shell 1. 4. The drive teeth 45 are arranged in a ring around the outer side of the toothed ring 42. The bottom end of the feed hopper 2 extends into the inside of the screen cylinder 41. When the motor drives the support roller 44 to rotate, the drive teeth 45 drive the toothed ring 42, which in turn causes the screen cylinder 41 to rotate around its own axis. At this time, small particles mixed in the feed will fall down through the holes on the surface of the screen cylinder 41 and eventually be discharged from the bottom of the protective shell 1. During this process, the arc-shaped feeding plate 46 on the inner side of the screen cylinder 41 rotates with the screen cylinder 41. Its shape is spiral. While the screen cylinder 41 rotates and screens, the feed can be transported to the side of the screen cylinder 41 away from the feed hopper 2 to complete the discharge. Thus, the feeding process can be completed at the same time as screening.
[0024] The striking component 47 includes a fixed sleeve 471, a rotating shaft 472 rotatably connected to the outer side of the fixed sleeve 471, arc-shaped connecting rods 474 fixedly connected to both sides of the rotating shaft 472, and striking blocks 475 rotatably connected to the outer side of the arc-shaped connecting rods 474. The striking component 47 is linearly arranged along the outer side of the support roller 44. The outer wall of the support roller 44 is fixedly connected to the inner wall of the fixed sleeve 471. A torsion spring 473 is fixedly connected to the inner side of the rotating shaft 472. The end of the torsion spring 473 away from the rotating shaft 472 is fixedly connected to the outer side of the fixed sleeve 471. The rotating shaft 472 is arranged in a ring along the outer side of the fixed sleeve 471. The striking blocks 475... The outer side of 5 contacts the outer side of the screen cylinder 41. The striking component 47 rotates synchronously with the support roller 44. When the support roller 44 rotates, it drives the fixed sleeve 471 and the rotating shaft 472 to move together. At this time, under the centrifugal force, the arc-shaped connecting rod 474 drives the rotating shaft 472 to deflect relative to the fixed sleeve 471. At this time, the torsion spring 473 is twisted by force, and the striking block 475 can contact the surface of the screen cylinder 41 during the rotation and generate a striking force. Through continuous striking, the screen holes of the screen cylinder 41 can be effectively prevented from being blocked, ensuring the screening efficiency and causing the pasture particles and impurities adhering to the inner side of the screen cylinder 41 or blocking the screen holes to fall off and complete the screening.
[0025] Working principle: In use, a motor is first installed on the outside of the protective shell 1 supported by the support leg 3, which can drive the top support roller 44 to rotate, thereby providing a power source for the entire device. Then, the hay enters the screening component 4 through the feed hopper 2. The inclined design at the bottom of the feed hopper 2 makes it easy for the hay to be guided smoothly into the screen cylinder 41. The fixing ring 43 supports the screen cylinder 41 and can also separate the toothed ring 42 and the drive tooth 45 from the screening part of the screen cylinder 41, ensuring the stability of the device during operation.
[0026] When the motor drives the support roller 44 to rotate, the drive tooth 45 drives the tooth ring 42, which in turn causes the screen cylinder 41 to rotate around its own axis. At this time, small particles of impurities mixed in the feed will fall down along the holes opened on the surface of the screen cylinder 41 and eventually be discharged from the bottom of the protective shell 1. During this process, the arc-shaped feeding plate 46 on the inner side of the screen cylinder 41 rotates with the screen cylinder 41. Its shape is spiral, which can transport the feed to the side of the screen cylinder 41 away from the feed hopper 2 while the screen cylinder 41 rotates and screens, thus completing the feeding process at the same time as screening.
[0027] At the same time, the striking component 47 rotates synchronously with the support roller 44. When the support roller 44 rotates, it drives the fixed sleeve 471 and the rotating shaft 472 to move together. At this time, under the centrifugal force, the arc-shaped connecting rod 474 drives the rotating shaft 472 to deflect relative to the fixed sleeve 471. At this time, the torsion spring 473 is twisted by force, and the striking block 475 can contact the surface of the screen cylinder 41 during the rotation and generate a striking force. Through continuous striking, the screen holes of the screen cylinder 41 can be effectively prevented from being blocked, ensuring the screening efficiency and causing the pasture particles and impurities that are adhered to the inside of the screen cylinder 41 or blocking the screen holes to fall off and complete the screening.
