Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically to a hand-operated and electric-powered wind separator. Background Technology

[0002] An air classifier is a device that uses airflow principles to separate materials, widely used in mining, metallurgy, chemical, and agricultural industries. By adjusting the airflow speed, it causes materials of different densities, shapes, and particle sizes to move along different trajectories under the influence of the airflow, thus achieving material separation and screening. An air classifier mainly consists of a fan, air duct, screen, and sorting chamber. It can efficiently separate light impurities from heavier materials and is suitable for cleaning and screening materials such as sand, grains, and ores. The advantages of an air classifier include high sorting accuracy, simple operation, low maintenance costs, and low energy consumption. It can adapt to the processing needs of different materials, especially excelling in separating light and heavy substances in material mixtures. Air classifiers are widely used in mineral processing, agricultural seed treatment, waste recycling, and other fields, and are a highly efficient and environmentally friendly sorting device.

[0003] Existing wind separators generally use an electric motor as the drive source to power the fan blades, so they need to be connected to a power source for use. For some temporary agricultural harvesting sites, which are usually used outdoors, a portable power source is required. However, when the power supply is unstable or no power can be provided on site, the wind separator will not work. At the same time, the operating parameters of electric wind separators are relatively fixed, which may not be able to meet the speed and force required for wind separation of some special materials. In this case, manual operation mode is required to ensure the normal use of the equipment.

[0004] Therefore, we propose a wind separator that can be used both as a hand and a flashlight. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a dual-purpose hand and electric wind separator. This application provides the following technical solution:

[0006] A dual-purpose hand and electric wind separator includes a fan blade cavity. A first rotating shaft is rotatably connected inside the fan blade cavity. A first pulley is coaxially fixedly connected to the end of the first rotating shaft away from the fan blade cavity. A second rotating shaft is rotatably connected to the outer periphery of the fan blade cavity through a bearing. A second pulley is coaxially fixedly connected to the end of the second rotating shaft away from the fan blade cavity. A belt is sleeved on the outer periphery of the first pulley and the second pulley.

[0007] The second rotating shaft is coaxially fixedly connected to a first gear at the end away from the second pulley. A protective cover is fixedly installed on the outer periphery of the fan blade cavity. A lead screw is rotatably connected to the inside of the protective cover through a bearing. A threaded block is threadedly connected to the outer periphery of the lead screw. A connecting block is fixedly installed on the side of the threaded block away from the protective cover. A second gear is rotatably connected to the end of the connecting block away from the threaded block through a bearing. The second gear meshes with the first gear. A first valve is coaxially fixedly connected to the top of the lead screw.

[0008] A motor is fixedly installed inside the fan blade cavity. A second bevel gear is coaxially fixedly connected to the output end of the motor. A first bevel gear is coaxially fixedly connected to the end of the first shaft near the second bevel gear. The first bevel gear and the second bevel gear mesh with each other. A handle is fixedly installed on the side of the second gear away from the connecting block. The outer periphery of the handle is provided with anti-slip texture.

[0009] As an alternative or supplement to the aforementioned dual-purpose hand and electric wind separator, a plurality of fan blades arranged in a ring are fixedly installed on the outer circumference of the first rotating shaft.

[0010] As an alternative or supplement to the above-mentioned dual-purpose hand and electric air separator, one side of the fan blade cavity is fixedly connected to an air separator chamber. The interior of the air separator chamber is rotatably connected to a third rotating shaft via a bearing. A baffle is coaxially fixedly connected to the outer periphery of the third rotating shaft. A second valve is coaxially fixedly connected to the end of the third rotating shaft away from the air separator chamber.

[0011] As an alternative or supplement to the aforementioned dual-purpose hand and electric air separator, the bottom of the air separator is fixedly connected to a fine material inlet on one side and a waste material inlet on the other side, and the top of the air separator is fixedly connected to a feed hopper.

[0012] As an alternative or supplement to the aforementioned dual-purpose hand and electric air separator, a support frame is fixedly installed at the bottom of the feed hopper.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] This invention features a motor fixedly installed inside the fan blade cavity, which drives the air separator through the meshing of two bevel gears. In electric mode, it can quickly process raw materials that do not require excessive fine processing, improving sorting efficiency. Simultaneously, a screw and threaded block structure is fixedly installed on the outside of the fan blade cavity, allowing the air separator to be manually driven through the engagement of gears and belts. In manual mode, the speed of the handle can be manually controlled, enabling more precise control of airflow and speed. This allows for more detailed sorting of fine raw materials requiring special processing. Therefore, this invention allows for flexible selection of manual or electric modes to adapt to different working conditions.

[0025] Please refer to Figure 1-4 As shown, this embodiment provides a dual-purpose hand and electric wind separator, including a fan blade cavity 2. A first rotating shaft 6 is rotatably connected inside the fan blade cavity 2. A first pulley 10 is coaxially fixedly connected to the end of the first rotating shaft 6 away from the fan blade cavity 2. A second rotating shaft 12 is rotatably connected to the outer periphery of the fan blade cavity 2 through a bearing. A second pulley 11 is coaxially fixedly connected to the end of the second rotating shaft 12 away from the fan blade cavity 2. A belt is sleeved on the outer periphery of the first pulley 10 and the second pulley 11. By setting the matching structure of the belt and the pulley, it can be more flexible when manually driving the device.

[0026] In an optional embodiment described above, a first gear 13 is coaxially fixedly connected to the end of the second rotating shaft 12 away from the second pulley 11. A protective cover 18 is fixedly installed on the outer periphery of the fan blade cavity 2. A lead screw 17 is rotatably connected to the inside of the protective cover 18 via a bearing. A threaded block 16 is threadedly connected to the outer periphery of the lead screw 17. A connecting block 15 is fixedly installed on the side of the threaded block 16 away from the protective cover 18. A second gear 14 is rotatably connected to the end of the connecting block 15 away from the threaded block 16 via a bearing. The second gear 14 meshes with the first gear 13. By setting the threaded connection between the lead screw 17 and the threaded block 16, a first valve 19 is coaxially fixedly connected to the top of the lead screw 17. By controlling the first valve 19, the lead screw 17 is driven to rotate, thereby controlling the movement of the threaded block 16 and flexibly controlling the position of the handle 20, thus preventing the handle 20 from rotating when the device is in electric mode.

[0027] Furthermore, a motor is fixedly installed inside the fan blade cavity 2. The output end of the motor is coaxially fixedly connected to a second bevel gear 9. The end of the first rotating shaft 6 near the second bevel gear 9 is coaxially fixedly connected to a first bevel gear 8. The first bevel gear 8 and the second bevel gear 9 mesh with each other. Multiple fan blades 7 arranged in a ring are fixedly installed on the outer periphery of the first rotating shaft 6. Through the meshing of the first bevel gear 8 and the second bevel gear 9, the motor can drive the first rotating shaft 6 to rotate, thereby driving the fan blades 7 to sort the raw materials.

[0028] In an optional embodiment described above, a wind classifier 3 is fixedly connected to one side of the fan blade cavity 2. A third rotating shaft 21 is rotatably connected to the inside of the wind classifier 3 via a bearing. A baffle 22 is coaxially fixedly connected to the outer periphery of the third rotating shaft 21. A second valve 23 is coaxially fixedly connected to the end of the third rotating shaft 21 away from the wind classifier 3. A fine material inlet 4 is fixedly connected to one side of the bottom of the wind classifier 3, and a waste material inlet 5 is fixedly connected to the other side. A feed hopper 1 is fixedly connected to the top of the wind classifier 3. A support frame 24 is fixedly installed at the bottom of the feed hopper 1. A handle 20 is fixedly installed on the side of the second gear 14 away from the connecting block 15. The outer periphery of the handle 20 is provided with anti-slip texture. Providing anti-slip texture on the outer periphery of the handle 20 helps to improve the user's grip and avoid operational errors caused by slipping.

[0029] When using this utility model, in electric mode, the raw materials to be sorted are fed into the air separator from the feed hopper 1. The motor fixedly installed inside the fan blade cavity 2 is started. The output end of the motor is coaxially fixedly connected to the second bevel gear 9. Through the meshing of the first bevel gear 8 and the second bevel gear 9, the motor drives the first rotating shaft 6, which is coaxially fixedly connected to the first bevel gear 8, to rotate, thereby sorting the raw materials entering the air separator 3. At the same time, the amount of raw materials falling into the air separator 3 is controlled by adjusting the second valve 23. At this time, the first valve 19 is adjusted to prevent the handle 20 from rotating when the motor is driven.

[0030] When using this utility model, in manual mode, the device can sort more fine raw materials. By manually controlling the wind speed and the force of hand cranking, a better sorting effect can be achieved. By adjusting the first valve 19, the threaded block 16, which is threaded to the lead screw 17, can be lowered to the desired position. When the second gear 14 and the first gear 13 are just meshed, the air separation structure can be driven by the handle 20 fixedly installed with the second gear 14. Through the meshing of the first gear 13 and the second gear 14, and the coaxial fixed connection of the other end of the second rotating shaft 12 with the second pulley 11, the device can be driven by hand cranking through the cooperation of the second pulley 11 and the first pulley 10 with the belt.

[0031] Whether it is electric or manual, the sorted raw materials will be discharged from the other end of the air separation chamber 3. The refined materials will fall through the refined material port 4, which is fixedly connected to one side of the air separation chamber 3. The raw materials of slightly lower quality will be discharged through the waste material port 5, which is fixedly connected to the other side of the air separation chamber 3.

[0032] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
