Description

Technical Field

[0001] The utility model relates to the technical field of air separation and recycling, and more specifically, to an air separation and debris removal conveyor. Background Art

[0002] Air separation utilizes the difference in suspension speed between the material and impurities to remove impurities with the help of wind. The purpose of air separation is to remove light impurities and dust, while also removing some heavier impurities such as stones and clods of earth. This method is commonly used for cleaning oilseeds such as cottonseed and rapeseed, as well as for dust and foreign matter removal in the grain and tobacco industries.

[0003] In real life, oilseed crops often have a tendency to have poorly plump grains. If a variety is chosen that is unsuitable for local climate or growing conditions, the grains will not be plump. These unpleasing oilseed crops can be recycled, for example, as part of animal feed, or, after fermentation and other processes, made into organic fertilizer or used in the production of biofuels.

[0004] A Chinese patent with authorization announcement number CN219899108U discloses an air separation and impurity removal conveyor, including a support rod, a mounting rod, a debris removal pipe, a screening box, a feed pipe, a mounting block a, a fan assembly, a threaded rod, a sliding rod, a rotating rod and a connecting rod. In this utility model, the fan assembly in the screening box blows away impurities and dust in the grain particles. The angle of the conveying mechanism is adjustable, which facilitates the adjustment of the height of the conveying mechanism, making the conveying mechanism more flexible to use.

[0005] However, in actual use, some materials with incomplete particles will also be blown away by the fan assembly and discharged from the exhaust pipe along with the impurities. These incomplete materials still have utilization value, and discharging them along with the impurities will easily cause waste of raw materials. Utility Model Content

[0051] Working principle of the utility model: When there is material that needs to be cleaned, the fan 24 is first started to transport the material from the feed hopper 18. The material falls evenly through the curved plate 21.

[0052] The cleaned material falls on the guide plate 20, slides into the discharge cylinder 19 through the guide plate 20, and falls onto the conveyor belt 30. The second motor 28 is started to drive the rotating shaft 29 to rotate, thereby driving the conveyor belt 30 to move.

By toggling the block that is movable between the screening cover 9 and the screening drum 8, the screening cover 9 hinged on one side of the screening drum 8 can be opened, thereby cleaning the impurities in the screening drum 8.

[0054] When the use angle of the conveying mechanism needs to be adjusted, the third motor 34 can be started to drive the threaded column 33 to rotate, thereby driving the sliding rod 35 threadedly connected to the surface of the threaded column 33 to slide inside the base frame 1, so that the mounting ear 36 is driven to move, and then the T-shaped transmission rod 37 is driven to rotate, and finally the rotation of the conveying mechanism is realized, thereby changing the angle between the conveying mechanism and the ground, thereby expanding the use scenario of the conveying mechanism.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
