Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine harvesting technology, and in particular to the roller cleaning mechanism of a cat's claw grass harvester. Background Technology
[0002] Cat's claw grass, also known as catnip, is a widely cultivated herbaceous plant belonging to the Lamiaceae family. The tuberous roots of cat's claw grass are the underground parts of the plant, referring to certain tissues of its roots (such as tubers or rhizomes), and have certain medicinal and cultivation value.
[0003] Currently, the harvesting of cat's claw roots usually involves hiring a large number of manual laborers, which is inefficient and costly. Therefore, to speed up the process, cat's claw root harvesting equipment is used when harvesting large quantities of cat's claw roots. The harvested cat's claw roots are fed into a conveying mechanism by a turning and turning mechanism, and then sent to a waste removal mechanism to remove the soil. However, because the soil carried out by the cat's claw roots is quite moist, it easily clogs the screen mesh, affecting the subsequent screening effect. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where the soil brought out by the roots of cat's claw grass is relatively moist, which easily clogs the mesh of the screen cylinder and affects the subsequent screening effect. This invention provides a drum cleaning mechanism for a cat's claw grass harvester, which can automatically clean the screen cylinder through a brush roller without manual intervention, thereby reducing the workload of manual screen cleaning and improving screening efficiency.
[0005] To achieve the above objectives, this utility model provides a drum cleaning mechanism for a cat's claw grass harvester, including a screen cylinder, a mounting cover, an adjusting component, and a brush roller. The screen cylinder is connected to a driving component, the mounting cover is disposed on one side of the screen cylinder, the adjusting component is connected above the mounting cover, and the brush roller is disposed above the screen cylinder and connected to the adjusting component. The adjusting component includes a connecting plate and an adjusting plate. One side of the connecting plate is connected to the mounting cover, the adjusting plate is rotatably connected to the connecting plate via a connecting shaft, and the adjusting plate is connected to the rotating shaft via a bearing seat. The brush roller is sleeved on the rotating shaft.
[0006] As a further description of the above technical solution: a fixed frame is connected inside the screen cylinder, a material distribution shaft is connected to the fixed frame, and multiple material distribution rods are provided on the material distribution shaft.
[0007] As a further description of the above technical solution: a protective cover is provided on the side of the screen cylinder away from the mounting cover, and the screen cylinder is located between the mounting cover and the protective cover.
[0008] As a further description of the above technical solution: two connecting plates and two adjusting plates are provided, and the rotating shaft is connected between the two adjusting plates.
[0009] As a further description of the above technical solution: the brush roller is provided with cleaning brushes in the circumferential direction.
[0010] As a further description of the above technical solution: the cleaning brush is made of iron wire.
[0011] As a further description of the above technical solution: the connection between the connecting plate and the mounting cover is a detachable connection.
[0012] The above technical solution has the following advantages or beneficial effects:
[0013] This invention features a brush roller mounted on a screen cylinder. As the screen cylinder rotates, the cleaning brushes on the brush roller effectively remove wet dirt adhering to the screen cylinder surface and mesh openings, reducing screen blockage and improving screening efficiency. The brush roller is fitted onto a rotating shaft, which is rotatably connected to an adjusting plate via a bearing seat.

[0023] Example 1:
[0024] like Figure 1-4 As shown, the cleaning mechanism of the cat's claw grass harvester of this utility model includes: a screen cylinder 1, a mounting cover 2, an adjusting component 3, and a brush roller 4. The screen cylinder 1 is connected to the driving component. The mounting cover 2 is disposed on one side of the screen cylinder 1. The adjusting component 3 is connected to the top of the mounting cover 2. The brush roller 4 is disposed above the screen cylinder 1 and is connected to the adjusting component 3. The adjusting component 3 includes a connecting plate 31 and an adjusting plate 32. One side of the connecting plate 31 is connected to the mounting cover 2. The adjusting plate 32 is rotatably connected to the connecting plate 31 through a connecting shaft 33. The adjusting plate 32 is connected to the rotating shaft 35 through a bearing seat 34. The brush roller 4 is sleeved on the rotating shaft 35.
[0025] In this embodiment, by setting the brush roller 4 on the screen cylinder 1, the cleaning brush 41 on the brush roller 4 can clean the surface of the continuously rotating screen cylinder 1 when the screen cylinder 1 rotates. The cleaning brush 41 on the brush roller 4 can effectively remove wet mud attached to the surface of the screen cylinder 1 and the mesh, reduce screen hole blockage, and improve screening efficiency. The brush roller 4 is sleeved on the rotating shaft 35, and the rotating shaft 35 is rotatably connected to the adjusting plate 32 through the bearing seat 34, so that when the screen cylinder 1 rotates, it can drive the brush roller 4 to rotate, which can enhance the cleaning effect. The adjusting plate 32 is rotatably connected to the connecting plate 31 through the connecting shaft 33, so that the brush roller 4 can always be attached to the top of the screen cylinder 1 under the action of gravity, which enhances the screening effect. The brush roller 4 can automatically clean the screen cylinder 1 without manual intervention, thereby reducing the workload of manual screen cleaning and improving screening efficiency.
[0026] The adjusting plate 32 is connected to the rotating shaft 35 via the bearing seat 34. The adjusting plate 32 can adjust the contact pressure between the brush roller 4 and the screen cylinder 1. Because the adjusting component is flexible, the brush roller 4 always maintains contact with the screen cylinder surface, ensuring maximum cleaning effect when the screen cylinder rotates. The adjusting component 32 ensures that the brush roller 4 always fits snugly against the screen cylinder 1, thereby enhancing the screening effect. This not only effectively solves the screen cylinder clogging problem but also improves the equipment's working efficiency through automatic cleaning. The flexibility of the adjusting component allows the equipment to adapt to different working needs, providing a more efficient and stable screening experience. At the same time, the automated design reduces manual intervention and maintenance requirements, lowering operating costs. The entire system design is simple and effective, suitable for improving the overall performance and operational convenience of cat's claw root harvesting equipment.
[0027] Specifically, there are two connecting plates 31 and two adjusting plates 32, and the rotating shaft 35 is connected between the two adjusting plates 32.
[0028] The driving component is a conventional drive motor that drives the drive wheel to rotate, which in turn drives the screen cylinder 1 to rotate.
[0029] like Figure 3 As shown, specifically, a fixed frame 5 is connected inside the screen cylinder 1, and a material distribution shaft 6 is connected to the fixed frame 5. Multiple material distribution rods 7 are installed on the material distribution shaft 6. The fixed frame 5 inside the screen cylinder 1 is connected to the material distribution shaft 6 and multiple material distribution rods 7. These material distribution rods 7 can help loosen and disperse the soil on the cat's claw root and break up the soil, making it easier to screen out the soil through the screen cylinder 1, so that the soil can be discharged more easily and the screening effect can be kept stable.
[0030] like Figure 1 and Figure 3As shown, specifically, the brush roller 4 is circumferentially equipped with cleaning brushes 41, which are made of iron wire. The use of iron wire for these cleaning brushes provides them with high hardness and strength, effectively removing dirt and debris adhering to the surface of the screen cylinder 1's mesh. Compared to traditional plastic or other material brushes, iron wire is less prone to bending and wear, maintaining high cleaning efficiency over long-term use. When rotating, the iron wire brush generates strong friction, especially in wet or sticky soil environments, effectively removing deposits and preventing dirt and impurities from clogging the screen holes. The iron wire also has strong wear resistance, allowing it to withstand friction during mechanical operation for extended periods, particularly when in contact with hard soil or debris, making it less prone to wear or breakage. This extends the equipment's lifespan and reduces the cost of frequent brush replacements due to wear.
[0031] like Figure 2 and Figure 3 As shown, specifically, the connection between the connecting plate 31 and the mounting cover 2 is a detachable connection; the detachable connection between the connecting plate 31 and the mounting cover 2 facilitates the maintenance and replacement of the adjustment component 3 and the brush roller 4.
[0032] Example 2:
[0033] like Figure 1 and Figure 4 As shown, specifically, a protective cover 8 is provided on the side of the screen cylinder 1 away from the mounting cover 2, and the screen cylinder 1 is located between the mounting cover 2 and the protective cover 8. During the screening process, the rapid movement of the screen cylinder 1 and the vibration of the screen mesh will cause mud to splash. The protective cover 8 helps to prevent this mud from causing harm or pollution to the surrounding environment or personnel. At the same time, it can also protect the screen cylinder 1 from external physical interference, provide a stable working environment for the screen cylinder, reduce the impact of the external environment on the screening operation, and thus improve the stability of equipment operation.
[0034] Working principle: By setting the brush roller 4 on the screen cylinder 1, the cleaning brush 41 on the brush roller 4 can clean the surface of the continuously rotating screen cylinder 1 when the screen cylinder 1 rotates. The cleaning brush 41 on the brush roller 4 can effectively remove wet mud attached to the surface of the screen cylinder 1 and the mesh, reduce screen hole blockage, and improve screening efficiency. The brush roller 4 is sleeved on the rotating shaft 35, and the rotating shaft 35 is rotatably connected to the adjusting plate 32 through the bearing seat 34, so that when the screen cylinder 1 rotates, it can drive the brush roller 4 to rotate, which can enhance the cleaning effect. The adjusting plate 32 is rotatably connected to the connecting plate 31 through the connecting shaft 33, so that the brush roller 4 can always be attached to the top of the screen cylinder 1 under the action of gravity, which enhances the screening effect. The brush roller 4 can automatically clean the screen cylinder 1 without manual intervention, thereby reducing the workload of manual screen cleaning and improving screening efficiency.
