[0002] E-commerce is a business activity centered on the exchange of goods, using information network technology as a means. It can also be understood as the activity of conducting transactions and related services electronically on the Internet, Intranet, and Value Added Network (VAN). It represents the digitalization, networking, and informatization of all aspects of traditional business activities.
[0003] To facilitate the classification of agricultural products, they are often graded and screened. During this process, e-commerce platforms can provide more precise market positioning and promotion strategies based on consumer needs and preferences. This not only helps to increase the added value and market competitiveness of agricultural products but also promotes their sales and circulation, bringing higher economic benefits to farmers.
[0004] Currently, roller grading machines are often used for grading and screening agricultural products. Since the roller grading machine is equipped with multiple grading guide plates, the graded agricultural products fall onto the guide plates one by one. However, there is a certain distance between the guide plates and the top of the roller grading machine. When the agricultural products fall onto the guide plates, they will be damaged due to the distance, which will affect the subsequent quality. Utility Model Content

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0025] Please see Figure 1-5 As shown, an agricultural product grading and screening device includes a roller grading machine 1. A conveying device 2 for conveying agricultural products is fixed on the left side of the roller grading machine 1. A filter plate 3 for filtering impurities in agricultural products is provided between the right side of the conveying device 2 and the top of the roller grading machine 1. A striking structure 5 for striking the filter plate 3 is provided on the back of the conveying device 2. Several vertical plates 7 are fixedly connected inside the roller grading machine 1. A guide plate 8 is fixedly fixed on the surface of the vertical plate 7. A buffer plate 9 is hinged to the top of the inner side of the vertical plate 7. A fixed plate 10 is fixedly connected between adjacent vertical plates 7. A connecting plate 11 is fixedly connected to the back of the fixed plate 10. Movable rods 12 are movably connected to both sides inside the connecting plate 11. One end of the movable rod 12 is hinged to the bottom of the buffer plate 9. A limiting plate 13 is fixedly connected to the surface of the movable rod 12. A first spring 14 is sleeved on the surface of the movable rod 12. The two ends of the first spring 14 are fixed to the limiting plate 13 and one side of the connecting plate 11, respectively. A connecting plate 15 is fixed to the other end of the movable rod 12.
[0026] The striking structure 5 includes a motor 51, a cam 52, a mounting plate 53, a moving rod 54, a fixed plate 55, and a second spring 56. The motor 51 is fixed to the back of the conveying device 2, and the output shaft of the motor 51 is fixed to the inside of the cam 52. The mounting plate 53 is fixed to the back of the roller classifier 1. The surface of the moving rod 54 is movably connected to the inside of the mounting plate 53, and one end of the moving rod 54 is fixed to one side of the fixed plate 55. The second spring 56 is sleeved on the surface of the moving rod 54, and both ends of the second spring 56 are fixed to the mounting plate 53 and the fixed plate 55, respectively. When the filter plate 3 is struck, the motor 51 can be started, which drives the cam 52 to rotate, so that the protruding part of the cam 52 rotates to the front, thereby pushing the fixed plate 55 and driving the moving rod 54 to move together, thereby striking the conveying device 2. When the cam 52 rotates to the starting position, the elastic force of the second spring 56 can drive the moving rod 54 back to the starting position, and so on.
[0027] The other end of the moving rod 54 is fixedly connected to a knocking block 6, which is made of rubber. This prevents wear on the surface of the filter plate 3 when the moving rod 54 moves and drives the knocking block 6 to knock on the filter plate 3.
[0028] The roller grading machine 1 has several collection boxes 17 on its surface, and the collection boxes 17 are located directly in front of the guide plate 8, which makes it convenient to collect and process the graded agricultural products in a unified manner.
[0029] A guide plate 4 is fixedly connected to the left side of the roller classifier 1, and the guide plate 4 is set at an angle, so as to guide the impurities that fall after filtration, which is convenient for subsequent collection and processing.
[0030] A buffer pad 16 is provided on the inner side of the buffer plate 9. The buffer pad 16 is made of rubber, which can protect agricultural products that fall on the inner side of the buffer plate 9, thereby reducing the damage to the agricultural products.
[0031] It should be noted that the two movable slots at one end of the connecting plate 11 are larger than the movable rod 12, so that when the movable rod 12 is pushed, there is room for movement in the movable slots inside the connecting plate 11.
[0032] Working principle: During use, agricultural products can be placed inside the conveying equipment 2 for transportation. As the agricultural products are transported to the right, they will fall onto the surface of the filter plate 3, and impurities in the agricultural products will be filtered through the filter plate 3. To improve the filtration effect, the filter plate 3 can be tapped by the tapping structure 5, and the filtered impurities can be guided and discharged by the guide plate 4. Then, the agricultural products will be graded and screened by the roller grading machine 1. The graded agricultural products will first fall onto the inner side of the buffer plate 9. When the buffer plate 9 is impacted by the agricultural products, it will drive the movable rod 12 and the limiting plate 13 to move, so that the limiting plate 13 squeezes the first spring 14. The first spring 14 can reduce the impact force on the buffer plate 9 through its own elastic force, thereby protecting the agricultural products. The buffered agricultural products will continue to fall downwards and slide onto the inner side of the guide plate 8, and then fall into the collection box 17 for collection.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
