Description

Technical Field

[0001] The utility model relates to the technical field of corn kernel impurity removal, in particular to a corn kernel impurity removal device. Background Art

[0002] Corn kernel impurity removal equipment, an essential component of agricultural processing, effectively removes various impurities from corn kernels. These impurities range from inorganic materials like stones and soil to organic materials like grass clippings, bedding, rotten corn kernels, and leftover stalks. However, in practice, processing corn kernels containing silk often presents technical challenges.

[0003] Corn silk, a naturally slender, soft, and easily tangled material, poses a significant challenge to the equipment's screening process. Due to its properties, corn silk easily becomes entangled and stuck in the mesh of the screening drum, causing blockage. This blockage not only significantly reduces the equipment's screening efficiency, forcing corn kernels that should otherwise pass quickly to stagnate, but more importantly, prolonged blockage can potentially cause wear and damage to the equipment's overall mechanical structure, impacting its long-term stable operation and service life.

[0004] A deeper analysis of this phenomenon revealed that corn silk's tendency to get stuck in the screening drum stems primarily from its unique physical properties. The silk's slenderness and softness make it easy for it to come into contact with and cling to the mesh of the screening drum. When large quantities of silk accumulate within the mesh, they form an insurmountable barrier, hindering the passage of corn kernels. Therefore, effectively addressing this problem and improving the equipment's screening efficiency became a pressing technical challenge. Utility Model Content

[0005] The main purpose of the utility model is to provide a corn kernel impurity removal device, which can effectively solve the problems raised in the background technology.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figures 1 to 5As shown, an efficient and multifunctional corn kernel impurity removal device is mainly composed of a power device 1, a support device 2, a series of screening and impurity removal cylinders (including a first screening and impurity removal cylinder 3, a second screening and impurity removal cylinder 4 and a third screening and impurity removal cylinder 5), and two side plates 6.

[0028] Two side discs 6 are meticulously mounted on support device 2. One side disc 6 is equipped with a power unit 1 to provide rotational power. The other side disc 6 features a cleverly designed opening on its end for connection to a connecting cylinder 8. Support device 2 is equipped with three different pore sizes for screening and removing impurities, tailored to meet the needs of corn kernels of varying particle sizes.

[0029] The outer end of the connecting barrel 8 is designed with a feed port 9 to facilitate the addition of corn kernels. A mounting tube 15 is installed on the side disc 6 with the connecting barrel 8. This mounting tube 15 is equipped with a second plug 16, the inner end of which is mounted an assembly rod 17. Particularly noteworthy is the fact that the assembly rod 17 is equipped with multiple impurity removal needles 18. When the corn kernels pass through the impurity removal needles 18, the corn silk is cleverly entangled around them, effectively removing impurities.

[0030] To further enhance the practicality and efficiency of the equipment, a protruding tube 10 is designed on the outer wall of the connecting tube 8. A first plug 11 is connected to the inner end of the protruding tube 10, and a fixing rod 12 is installed at the inner end of the first plug 11. Multiple cleaning brushes 13 are attached to the fixing rod 12. These cleaning brushes 13 effectively remove material that may be stuck in the screening and debris removal drum, ensuring smooth operation of the equipment.

[0031] The support device 2 consists of two rings and side bars, which are cleverly placed between the two rings and present an integrated design. Two adjacent rings are connected by bolts to form a stable support frame for multiple screening and impurity removal drums.

[0032] Bolts secure the side plate 6 to the support assembly 2, ensuring stability. Bolts also secure the mounting tube 15 to the side plate 6. A threaded connection is used between the mounting tube 15 and the second plug 16, facilitating easy installation and removal. Similarly, a threaded connection is used between the second plug 16 and the assembly rod 17.

[0033] The design of the assembly rod 17 is very clever, wherein one end is provided with a threaded head and the other end is provided with a threaded portion. A plurality of assembly rods 17 can be flexibly assembled through the threaded heads and the threaded portions to adapt to different impurity removal requirements.

[0034] On the assembly rod 17, a plurality of impurity removal needles 18 are evenly distributed and welded to the rod body to ensure uniformity and high efficiency of the impurity removal effect.

[0035] The cleaning brush 13 is fixed to the rubber sleeve by heat-melting, and the rubber sleeve is then mounted on the fixed rod 12. Multiple cleaning brushes 13 are also evenly spaced on the fixed rod 12. When the fixed rod 12 is rotated, the material in the feed port 9 and the connecting tube 8 can be moved, thereby preventing blockage. The first plug 11 and the convex tube 10 are also connected by a threaded connection to ensure the tightness and stability of the connection.

[0036] The lower ends of the three screening and impurity removal cylinders are provided with discharge ports 7, through which corn kernels of different diameters can be discharged.

[0037] Impurity removal process: Corn kernels enter connecting barrel 8 through feed port 9. As they pass through mounting tube 15, they encounter impurity removal needles 18 mounted on assembly rod 17. Due to the design of impurity removal needles 18, the corn kernels entangle impurities adhering to their surfaces with silk impurities, thus completing the initial impurity removal process.

[0038] After preliminary impurity removal, the corn kernels enter the first screening and impurity removal drum 3. Depending on the pore size of the screening and impurity removal drum, kernels of different particle sizes are sorted into different areas or the next level of screening and impurity removal drum. This process removes large impurities and substandard kernels. The kernels then enter the second and third screening and impurity removal drums 4 and 5, where, after multiple rounds of screening, they ultimately yield kernels that meet the requirements.

[0039] Cleaning and anti-blocking process: When blockage is found in the screening and impurity removal cylinder or the connecting cylinder 8 during the operation of the equipment, the cleaning system can be started by rotating the fixing rod 12.

[0040] The cleaning brushes 13 on the fixed rod 12 move as the fixed rod 12 rotates. These cleaning brushes 13 can effectively remove materials that may be stuck in the screening and impurity removal cylinder and the connecting cylinder 8.

[0041] The movement of the cleaning brush 13 will drive the material movement in the feed port 9 and the connecting tube 8, thereby preventing the occurrence of blockage. In order to ensure the long-term stable operation of the equipment, it is also necessary to regularly check and clean the impurity removal needle 18 and the cleaning brush 13 to ensure their impurity removal and cleaning effects.
