Description

Technical Field

[0001] This utility model relates to the field of material cleaning technology, specifically a cleaning machine with dual frequency conversion for air and vibration adjustment. Background Technology

[0002] This utility model relates to the technical field of cleaning machines, which are widely used in agriculture, food processing, grain processing, and other fields. They are primarily used for screening, cleaning, and separating materials. By adjusting physical parameters (such as wind force and vibration frequency), they separate impurities and particles with different properties from the materials, thereby improving material quality. The cleaning machine has functions such as screening, impurity removal, and classification. It can clean away dirt, dust, stones, and chaff from materials, maintaining their cleanliness, and can also accurately separate materials according to their different physical properties, improving processing efficiency. During use, the cleaning machine can also adjust the feeding speed and processing intensity according to specific requirements, thereby optimizing the process, saving time and labor costs, and simplifying production steps. The application of this equipment not only ensures the quality and market competitiveness of the final product but also has environmental protection and energy-saving characteristics, effectively reducing the spread of pollutants such as dust and resource waste.

[0003] The new cleaning machine represents a technological upgrade from traditional equipment, employing a dual-frequency conversion design to specifically address the issue of unsatisfactory material separation results. Traditional cleaning machines typically use a single motor to drive both airflow and vibration frequency, making precise adjustment difficult for different specific gravities or material characteristics. The new machine, however, uses two independent motors, allowing for independent adjustment of airflow and vibration frequency. This design enables flexible control over different material characteristics, improving the adaptability and accuracy of material separation. Simultaneously, the newly added waterfall discharge design ensures more thorough material separation, significantly enhancing work efficiency and cleaning quality. This technological breakthrough not only significantly improves separation performance but also expands the equipment's applicability, providing a more advanced and efficient solution for modern agriculture and industrial production.

[0004] Existing traditional cleaning machine technology uses a single motor to drive both airflow and vibration frequency. This structure has the technical problem of not being able to precisely adjust for the characteristics of different materials (such as specific gravity, particle size, shape, etc.). Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cleaning machine with dual frequency conversion for wind and vibration regulation. This solves the technical problem that existing traditional cleaning machine technologies rely on a single motor to simultaneously drive wind and vibration, which makes it impossible to precisely adjust the airflow for the characteristics of different materials.

[0018] In this embodiment, the independent air separation structure includes an air separator 7, which is fixedly installed on the upper wall of the main frame 1. The output end of the air separator 7 is connected to the lower end of the screening box 2 and is located at the lower end of the independent vibrating screen structure. The air inlet of the air separator 7 is located outside the screening box 2. The output ends of the fine material discharge pipe 4, the light material discharge pipe 5, and the heavy material discharge pipe 6 are the air outlets of the cleaning machine. An independent drive unit is provided on the air separator 7.

[0019] In this embodiment, the independent drive unit includes a first motor 8, with a drive pulley 9 fixedly installed at the drive end of the first motor 8. The air separator 7 is a centrifugal fan, and centrifugal blades 11 are rotatably installed inside the air separator 7. A driven pulley 12 is fixedly installed at one end of the centrifugal blades 11, and a transmission belt 13 is connected to the drive pulley 9 and the driven pulley 12. The independent drive unit further improves the operational stability and adjustment efficiency of the air separator 7, and achieves dynamic control of the wind force through precise adjustment of the centrifugal fan.

[0020] In this embodiment, the independent vibrating screen structure includes a vibrating screen frame 14, one end of which is rotatably installed inside the screening box 2. An independent vibrating part is installed inside the screening box 2. Two electric rollers 15 are rotatably installed on the vibrating screen frame 14. A material conveyor belt 16 is connected to the two electric rollers. The material conveyor belt 16 is provided with ventilation holes.

[0021] In this embodiment, the independent vibration unit includes a second motor 17, which is fixedly installed on the lower wall of the screening box 2. A turntable 18 is fixedly installed on the drive end of the second motor 17, and a rocker arm 19 is rotatably installed on the turntable 18. The other end of the rocker arm 19 is rotatably installed on the lower wall of the vibrating screen frame 14. The vibrating screen frame 14 in the independent vibrating screen structure is designed to be flexible, ensuring that the material can be fully vibrated and screened. The independent design of the vibrating screen structure enables precise control of the vibration frequency, ensuring that the equipment operation effect meets the needs of different materials.

[0022] In this embodiment, a light material discharge guide plate 20 is installed on the main frame 1 at the lower end of the light material discharge pipe 5, a heavy material discharge guide plate 21 is installed on the main frame 1 at the lower end of the heavy material discharge pipe 6, and a fine material discharge box 22 is installed on the main frame 1 at the lower end of the fine material discharge pipe 4.

[0023] In this embodiment, a support frame 23 is fixedly installed at the lower end of the main frame 1, and a walking wheel 24 is rotatably installed on the support frame 23.

[0025] The materials to be screened are added to the feeding hopper 3. The feeding hopper 3 is designed to ensure that the materials are evenly distributed into the screening box 2, avoiding blockage or uneven material distribution. The feeding speed of the feeding hopper 3 is adjusted according to the actual screening requirements to ensure that the materials enter the screening box 2 at a uniform speed, thereby improving the screening effect. By controlling the operating status of the first motor 8, the wind force of the centrifugal fan is adjusted. The appropriate wind force is selected according to the specific gravity of the material so that light impurities can be discharged through the light material discharge pipe 5. By controlling the drive end of the second motor 17, the vibration frequency of the vibrating screen structure is adjusted so that the materials can vibrate fully. Heavy materials are discharged through the heavy material discharge pipe 6, while fine materials are screened out evenly. The wind force and vibration frequency parameters are reasonably matched according to the material characteristics (such as particle size and specific gravity) to ensure separation adaptability and accuracy.

[0026] Observe the material flow inside screening box 2 to ensure that the material can be evenly distributed and fully screened under the action of vibrating screen and wind force; monitor the discharge status: ensure that light material, fine material and heavy material are discharged smoothly through the corresponding discharge pipes to avoid material blockage or classification errors.

[0027] Light materials are discharged from the guide plate of the light material discharge pipe 5 and enter the collection area, while heavy materials are discharged through the guide plate of the heavy material discharge pipe 6 and separated cleanly. Fine materials enter the fine material discharge box 22, thus achieving complete classification and processing.

[0028] After the material screening is completed, promptly clean the residual material inside the feeding hopper 3, screening box 2, and discharge pipe to ensure the cleanliness of the equipment and its normal use next time.

[0029] If a change of work site is required, the cleaning machine can be moved to a new location using the equipment's wheels 24.
