Description

Technical Field

[0001] This utility model relates to the technical field of peanut processing equipment, specifically to a peanut kernel sieving device. Background Technology

[0002] During peanut processing, peanut kernels vary in size and typically require sieving to meet different product requirements. Currently, traditional sieving methods rely heavily on manual screening or simple vibrating screens. While manual screening is simple to operate, it is extremely inefficient, labor-intensive, and struggles to guarantee uniformity and consistency in sieving. Although existing vibrating screens improve sieving efficiency to some extent, they typically employ a single-layer screen design, making it impossible to perform multiple sievings of different sizes. This results in unsatisfactory sieving results, with some peanuts failing to be classified according to their intended size. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a peanut kernel sieving device. This device solves the problem that traditional sieving methods rely heavily on manual screening. While manual screening is simple to operate, it is extremely inefficient, labor-intensive, and difficult to guarantee uniformity and consistency. Although existing vibrating screens improve sieving efficiency to some extent, they typically use a single-layer screen design, which cannot perform multiple sievings of peanut kernels of different sizes, resulting in unsatisfactory sieving results and some peanut kernels failing to be classified according to their expected size.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0031] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0032] like Figure 1-4As shown in the figure, this utility model embodiment proposes a peanut kernel sieving device, including a frame 10, a sieving mechanism, and a driving mechanism; the sieving mechanism includes a box 20 installed on the top of the frame 10 and at least two vertically arranged sieving plates 21, the box 20 having a discharge port 22 corresponding to each of the sieving plates 21, and one end of each sieving plate 21 being rotatably disposed at the discharge port 22; the driving mechanism includes a driving member 30 disposed on the side of the box 20 away from the discharge port 22, the driving member 30 being movably connected to the end of each sieving plate 21 away from its rotating end, so as to drive each sieving plate 21 to swing up and down relative to the box 20.

[0033] In this embodiment of the invention, during operation, peanut kernels enter the screening mechanism from the upper part of the housing 20. After the drive mechanism is activated, the drive component 30 drives each screening plate 21 to swing up and down around one end of the discharge port 22, causing the peanut kernels to vibrate and displace on the screening plates 21. Smaller peanut kernels fall through the sieve holes of the upper screening plate 21 to the lower screening plate 21, while larger peanut kernels remain on the upper screening plate 21 and are discharged through the corresponding discharge port 22. The peanut kernels falling into the lower screening plate 21 continue to be screened, further separating smaller peanut kernels, which are then discharged from the corresponding discharge ports 22 according to their different sizes. Alternatively, three or more layers of screening plates 21 can be used according to actual processing needs, allowing the peanut kernels to undergo finer grading and screening, enabling precise classification of peanut kernels of different sizes to meet product processing requirements.

[0034] Secondly, such as Figure 2 As shown in this embodiment of the invention, a guide plate 24 is provided on the same side of each of the discharge ports 22. The guide plate 24 is inclined. Since peanut kernels continuously fall into the corresponding discharge ports 22 during the screening process, the inclined guide plate 24 can guide the peanut kernels to flow in a fixed direction, preventing them from accumulating or clogging near the discharge ports 22, thus improving the smoothness of screening. At the same time, after being guided by the guide plate 24, the peanut kernels can be more easily collected and processed later, thereby improving the overall automation level and reducing manual intervention. In addition, the guide ports of the two guide plates 24 are staggered. The staggered arrangement can reasonably allocate space, making the equipment structure more compact and reducing the overall volume.

[0035] Specifically, such as Figure 3As shown in this embodiment of the present invention, the driving component 30 includes a driving plate 31 slidably disposed on one side of the housing 20 and a driving block 32 slidably disposed on the side wall of the housing 20 and connected to the driving plate 31. The driving plate 31 is hinged to the sieve plate 21. A mounting bracket 40 is provided on the outer side of the housing 20. A cylindrical cam 33 is rotatably disposed on the mounting bracket 40. The cylindrical cam 33 is provided with a driving groove 34. The driving block 32 is provided with a driving pin 35, which is slidably engaged with the driving groove 34. By rotating the cylindrical cam 33, the driving groove 34 on it is driven to perform periodic movements. Since the driving pin 35 on the driving block 32 is slidably engaged in the driving groove 34, the driving block 32 will slide up and down reciprocally on the side wall of the housing 20 as the driving groove 34 moves. The up and down reciprocating sliding of the driving block 32 further drives the driving plate 31 to slide up and down reciprocally along one side of the housing 20, and through the rotating end of the sieve plate 21, it is made to swing up and down. Due to the periodic up-and-down swing of the sieve plate 21, the peanut kernels continuously roll and move on the surface of the sieve plate 21, allowing peanut kernels of different sizes to be screened sequentially through the sieve plate 21 and discharged through the corresponding discharge port 22.

[0036] Secondly, in this embodiment of the utility model, a drive wheel 36 is rotatably provided on the mounting frame 40. The drive wheel 36 is coaxially connected to the cylindrical cam 33. A drive motor (not shown) can be mounted on the mounting frame 40 or the frame 10 so that the drive wheel 36 can be driven to rotate through the drive motor, thereby driving the cylindrical cam 33 to rotate synchronously.

[0037] And, as Figure 4 As shown in this embodiment of the present invention, the side wall of the drive plate 31 is provided with a limiting block 37, and the inner side wall of the box 20 is provided with a limiting groove 23. The limiting block 37 is slidably engaged with the limiting groove 23. The driving plate 31 is slidably moved along a fixed trajectory by the limiting block 37, so that the swing angle of the sieve plate 21 remains consistent. This avoids the problem of reduced sieve efficiency or inaccurate classification of sieved particles caused by motion deviation, so as to make the sieve of peanut kernels more uniform and improve the sorting accuracy of particles of different specifications.

[0038] Based on the above solutions, such as Figure 1 As shown in this embodiment of the invention, the top of the housing 20 is provided with a mounting part 25, which has several mounting holes 251 for mounting a feed hopper (not shown). The feed hopper can be securely mounted to the mounting holes 251 by means of bolts, clips, etc., to prevent the feed hopper from shaking or shifting during operation. Furthermore, the frame 10 has a discharge hopper 11, the feed end of which is located below the sieve plate 21. The discharge hopper 11 can directly receive the sieved peanut kernels, reducing material spillage and thus improving collection efficiency.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
