They have excellent effects on human growth and development, strengthening the body, and preventing diseases. Agricultural products such as chestnuts, peanuts, and soybeans need to be screened according to factors such as size after preliminary processing. Manual screening requires a lot of manpower and resources, and machine screening devices have also appeared on the market.

[0003] In the prior art, such as the screening device for agricultural product production and processing disclosed in Chinese Patent Publication No. CN221816620U, there is a base plate, an agricultural product container, a screening cylinder, a first trumpet-shaped screen, a second trumpet-shaped screen, a third trumpet-shaped screen, a material blocking mechanism, and a driving mechanism. The agricultural product container and the screening cylinder are both fixedly installed on the top of the base plate by a bracket. The agricultural product container is located on the left side of the screening cylinder, and the top of the agricultural product container has an open structure.

[0004] The aforementioned patented technology controls agricultural products to be tumbled and screened sequentially inside the first, second, and third funnel-shaped screens. However, in actual use, the agricultural products roll from top to bottom inside the screens. Due to the high rolling speed, the agricultural products stay at the top of the screens for a short time, resulting in some products being missed during screening, thus affecting the screening effect. In addition, different agricultural products have different sizes, and the aforementioned screening device cannot adjust the size of the screen holes during use, making it unable to screen agricultural products of different sizes, thereby reducing the screening effect of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a screening device for agricultural product production and processing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an agricultural product production and processing screening device, comprising a base and a cylinder, wherein a receiving box is movably placed on the top of the base, a feeding bin is fixedly connected to the top of the cylinder, a fixed shaft is fixedly installed on both sides of the outer wall of the cylinder, a drive motor is fixedly installed on the side of one of the fixed shafts, a spiral blade is provided inside the cylinder, an opening is provided at the bottom of the cylinder, and three mounting slots are equidistantly provided at the bottom of the cylinder, wherein a first screen plate, a second screen plate, and a third screen plate are movably installed inside the three mounting slots respectively.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1-5As shown, this utility model provides a technical solution: an agricultural product processing and screening device, including a base 1 and a cylinder 2. A receiving box 11 is movably placed on the top of the base 1, and a feeding bin 21 is fixedly connected to the top of the cylinder 2. Fixed shafts 22 are fixedly installed on both sides of the outer wall of the cylinder 2, and a drive motor 3 is fixedly installed on the side of one of the fixed shafts 22. Spiral blades 31 are provided inside the cylinder 2, and an opening 201 is opened at the bottom of the cylinder 2. There are three mounting slots 202 equidistantly opened at the bottom of the cylinder 2. A first screen plate 4, a second screen plate 5, and a third screen plate are movably installed inside the three mounting slots 202, respectively. 6. There are three receiving boxes 11, which are located at the bottom of the first screen plate 4, the second screen plate 5, and the third screen plate 6, respectively. A mounting plate 12 is fixedly installed on the top of the base 1, and a fixed shaft 22 is fixedly installed inside the mounting plate 12. The surface of the spiral blade 31 is in contact with the inner wall of the cylinder 2, and one side of the spiral blade 31 is fixedly connected to the output end of the drive motor 3. The top of the first screen plate 4 has a hole 401, the top of the second screen plate 5 has a hole 501, and the top of the third screen plate 6 has a hole 601. The diameters of the holes 401, 501, and 601 gradually increase in size.

[0025] In this embodiment, the bottom of the feeding bin 21 is connected to the inside of the cylinder 2. When agricultural products are fed into the feeding bin 21, they can be stored inside the cylinder 2. The drive motor 3 drives the spiral blades 31 to rotate, which can horizontally push the agricultural products inside the cylinder 2. By adjusting the rotation speed of the spiral blades 31, the movement speed of the agricultural products inside the cylinder 2 can be adjusted. The agricultural products pass through the first sieve plate 4, the second sieve plate 5, and the third sieve plate 6 in sequence. The sizes of the holes 401, 501, and 601 increase sequentially, which can screen and classify agricultural products of different sizes. When the spiral blades 31 rotate, they can turn the agricultural products over to avoid the accumulation of agricultural products and affect the screening effect. The receiving box 11 can collect the screened agricultural products, and the opening 201 at the bottom of the cylinder 2 can discharge the screened waste material for subsequent use.

[0026] Example 2

[0027] like Figures 1-5 As shown, the installation structures of the first screen plate 4, the second screen plate 5, and the third screen plate 6 are all the same. The third screen plate 6 has a snap-fit ​​block 61 on both sides. An extension plate 62 is fixedly connected to the bottom of the snap-fit ​​block 61. The inner wall of the mounting groove 202 has a slot 203 on both sides. The snap-fit ​​block 61 fits the shape of the slot 203. The bottom of the third screen plate 6 has a groove 602. A spring 63 is fixedly installed inside the groove 602. One end of the spring 63 is fixedly connected to the side of the snap-fit ​​block 61.

[0028] In this embodiment, by opening a slot 203 on the side of the mounting groove 202, the snap-fit ​​block 61 on the side of the third sieve plate 6 is embedded and installed inside the slot 203 to install and fix the third sieve plate 6. The snap-fit ​​block 61 is movably installed inside the groove 602. By pushing the extension plate 62, the snap-fit ​​block 61 is moved away from the slot 203 and falls out from inside it, thus releasing the fixation of the third sieve plate 6. The spring 63 is connected and fixed to the snap-fit ​​block 61, so that the snap-fit ​​block 61 can be reset by itself after being released. The sieve plates with different sizes of holes can be replaced, thereby facilitating the replacement of the first sieve plate 4, the second sieve plate 5 and the third sieve plate 6, and facilitating the screening and processing of agricultural products of different sizes.

[0029] Working principle: The agricultural products to be screened are placed inside the feeding hopper 21, allowing them to roll and be stored inside the cylinder 2. Three receiving boxes 11 are placed at the bottom of the first screen plate 4, the second screen plate 5, and the third screen plate 6, respectively. An external power source starts the drive motor 3, which rotates the spiral blades 31. The spiral blades 31 push the agricultural products from left to right, causing them to tumble. The agricultural products pass sequentially through the tops of the first screen plate 4, the second screen plate 5, and the third screen plate 6. Agricultural products of different sizes fall through holes 401, 501, and 601, respectively, thus screening and classifying the agricultural products of different sizes. The rotation of the spiral blades 31 is then adjusted. The speed can be adjusted to control the movement speed of agricultural products inside the cylinder 2, preventing the agricultural products from moving too fast and affecting the screening effect. The opening 201 at the bottom of the cylinder 2 can discharge the screened waste. The three receiving boxes 11 collect agricultural products of different sizes. When it is necessary to replace the screen plate with a different hole size, push the extension plate 62 to make the locking block 61 move away from the slot 203 and fall out from its interior, which can release the fixation of the third screen plate 6. When replacing other screen plates, install the locking block 61 in its slot 203, so as to facilitate the replacement of the first screen plate 4, the second screen plate 5 and the third screen plate 6, and facilitate the screening and processing of agricultural products of different sizes.
