Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a wheat metal impurity removal device. Background Art

[0002] During the harvesting, drying, storage, and transportation of wheat, impurities such as stones, metals, wheat straw, and dust may be mixed in. These impurities not only affect the quality of wheat, but may also cause wear and damage to production equipment and even pose a threat to the safety of workers. Therefore, it is necessary to remove impurities from wheat to ensure product quality and smooth production.

[0003] However, the existing wheat impurity removal device can only perform rough screening and preliminary cleaning of wheat, removing some large impurities and some light impurities, such as straw, stones, plastic, etc. Since the physical properties of metal impurities and wheat are slightly different, it is difficult to effectively separate them through conventional screening methods. Therefore, a new type of wheat impurity removal device is needed to improve the effective separation ability of metal impurities mixed with wheat. Summary of the invention

[0004] In order to overcome the shortcoming that the existing wheat impurity removal device is difficult to effectively separate the metal impurities mixed in the wheat, the utility model aims to provide a wheat metal impurity removal device which can effectively separate the metal impurities mixed in the wheat.

[0006] As a further preferred solution, the transmission mechanism includes a belt assembly, a gear, and an annular rack. The front end of the roller is provided with a belt assembly, the front side of the connecting shell is rotatably provided with a gear, the gear is rotatably connected to the belt assembly, the front side of the connecting shell is rotatably provided with an annular rack, and the annular rack and the gear are meshed with each other.

[0007] As a further preferred embodiment, the separation mechanism includes an annular rotating shaft and a scraper.

[0010] As a further preferred solution, a hook is also included, and a hook is arranged downward on the top of the left side of the mounting frame.

It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning.

[0020] Embodiment: A wheat metal impurity removal device, such as Figure 1-Figure 4 As shown, it includes a mounting frame 1, a feed hopper 2, a fixed column 3, a connecting shell 4, a motor 5, a roller 6, a transmission mechanism 7 and a separation mechanism 8. The mounting frame 1 has a square opening on the upper part, on which the feed hopper 2 is arranged. The fixed column 3 is fixedly installed at the bottom of the feed hopper 2 by two L-shaped rods. A connecting shell 4 is arranged at the bottom of the feed hopper 2 by welding. The connecting shell 4 surrounds the fixed column 3. A discharge port 41 and a waste port 42 are arranged at the bottom of the connecting shell 4. The motor 5 is installed at the upper rear side of the mounting frame 1. A roller 6 is rotatably arranged in the middle of the feed hopper 2. One end of the roller 6 is fixedly connected to the output end of the motor 5, and the other end is connected to a transmission mechanism 7 for transmitting power. A separation mechanism 8 for separating metal impurities is arranged between the connecting shell 4 and the fixed column 3.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the transmission mechanism 7 includes a belt assembly 71, a gear 72, and an annular rack 73. The belt assembly 71 is arranged at the front end of the roller 6, and the gear 72 is rotatably arranged on the front side of the connecting shell 4. The gear 72 is rotatably connected to the belt assembly 71, and the annular rack 73 is rotatably arranged on the front side of the connecting shell 4. The annular rack 73 and the gear 72 are meshed with each other.

[0022] like Figure 4 As shown, the separation mechanism 8 includes an annular shaft 81 and a scraper 82. The annular shaft 81 is rotatably arranged between the connection shell 4 and the fixed column 3. The annular shaft 81 surrounds the fixed column 3 and is fixedly connected to the annular rack 73. The scraper 82 is arranged on the right wall of the connection shell 4. The scraper 82 contacts the annular shaft 81. The annular shaft 81 is made of a neodymium iron boron permanent magnet and has strong magnetism.

[0023] When in use, the staff turns on the motor 5 and pours the wheat mixture containing metal impurities into the feed hopper 2. The motor 5 drives the roller 6 to rotate, and the roller 6 drives the belt assembly 71 to rotate, so that the belt assembly 71 drives the gear 72 to rotate, and the annular rack 73 is driven to rotate due to the engagement with the gear 72, and then the annular shaft 81 fixed to the annular rack 73 is also driven to rotate, so that the wheat mixture in the feed hopper 2 flows downward counterclockwise along the space between the connecting shell 4 and the fixed column 3. During the flow, the metal impurities are adsorbed on the surface of the annular shaft 81 made of neodymium iron boron permanent magnets, and the remaining wheat mixture falls into the discharge port 41 below for collection, and then the metal impurities adsorbed on the annular shaft 81 will continue to move upward counterclockwise until they contact the scraper 82, and the scraper 82 can scrape off the adsorbed metal impurities, and the scraped metal impurities will fall into the waste port 42 below for collection. After one impurity removal, there may still be a small amount of metal impurities remaining. The staff can pour the wheat mixture collected at the discharge port 41 into the feed hopper 2 again to repeat this process. After multiple adsorption and impurity removal by the separation mechanism 8, most of the metal impurities in the wheat mixture can be removed.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, a stirring block 9 is also included. A plurality of stirring blocks 9 of different lengths are fixedly connected to the middle of the roller 6. The stirring block 9 can stir the wheat and metal impurity mixture evenly, making it easier to separate the metal impurities.

[0025] like Figure 1 and Figure 2 As shown, a hook 10 is also included. The top of the left side of the mounting frame 1 is provided with a hook 10 facing downward. The hook 10 can be used to hang some tools for collecting wheat and impurities, thereby improving the practicability of the device.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
