Abstract
Description
Technical Field
[0001] This utility model relates to the field of peanut processing technology, and in particular to a novel screening device for peanuts. Background Technology
[0002] The peanut (Arachis hypogaea L.) is an annual herbaceous plant belonging to the genus Arachis in the legume family. It has root nodules; its stems are erect or creeping and angular; its stipules are hairy; its leaflets are ovate-oblong or obovate, with a blunt apex, a nearly rounded base, and entire margins; its corolla is yellow or golden-yellow; its style extends beyond the calyx tube; its pods are long, inflated, and have a thick pericarp; it flowers from June to July and fruits from September to October. After flowering and fertilization, the ovary falls into the dark ground to grow and bear fruit, hence the name "ground peanut" (literally "ground peanut").
[0003] Peanuts have many uses, including as a snack, processed food, and oil extraction. Before processing, peanuts often need to be sieved to remove defective or smaller peanuts, ensuring the quality of processed food and peanut oil. Existing technologies for peanut sieving, such as the peanut screening device in CN222766727U, use a traditional filter screen method. Although the structure is simple, it is difficult to peel and sieve the peanut shells, resulting in poor sieving effect. Furthermore, it can only sieve peanuts based on size. If the peanuts are hollow or infested with insects, they are difficult to separate, leading to unsatisfactory results.
[0004] Therefore, existing technologies need further improvement. Utility Model Content
[0005] This utility model proposes a novel screening device for peanuts to overcome the shortcomings of existing technologies.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel screening device for peanuts, comprising a shell-breaking component, a multi-stage screening section, and a sorting section, arranged sequentially from top to bottom. The shell-breaking component is located below the feed inlet, with a first pressure plate above it. Second pressure plates are arranged on the left and right sides inside the shell-breaking component. A vibrating element is arranged at the bottom of the shell-breaking component. The bottom of the shell-breaking component can communicate with the multi-stage screening section. The multi-stage screening section includes multiple inclined screening plates. The sorting section is provided with a water inlet, a water outlet, and a screen hinged to the side wall. A collection area is provided at the bottom and rear of the sorting section.
[0007] In a preferred embodiment of this application, the screening device further includes an outer shell, a hydraulic lifting frame is provided on the side wall of the outer shell, the top of which is connected to the first pressure plate, and an electric push rod is provided between the second pressure plate and the inner wall of the shell breaking component.
[0008] In a preferred embodiment of this application, a pressure sensor is provided inside the bottom wall of the shell-breaking component, and a pressure sensor is also provided inside the second pressure plate. The bottom wall of the shell-breaking component is provided with an opening and closing door.
[0009] In a preferred embodiment of this application, a vibration motor is integrated into the inclined screening plate, and the mesh diameter of the inclined screening plate gradually decreases from top to bottom.
[0010] In a preferred embodiment of this application, a storage box is provided at the lowest end of the inclined screening plate. The storage box has a pull-out structure and is used for temporary storage.
[0011] In a preferred embodiment of this application, a water storage tank is provided on the side of the outer casing, the water storage tank is connected to the interior of the sorting section, and the water inlet and outlet are equipped with electrically controlled valves.
[0012] In a preferred embodiment of this application, the top of the scooping net is hinged to the top of the sorting section, an electric rotating shaft is provided at the connection between the scooping net and the sorting section, a sliding door is provided between the sorting section and the multi-stage screening section, and the collection area is located below one side of the sliding door and at the bottom of the sorting section.
[0013] In summary, the beneficial effects of this utility model are as follows:
[0014] This application utilizes the cooperation of a first and second pressure plate to break peanut shells. Through vertical and horizontal squeezing, the peanuts are opened, and the vibrating structure separates the peanuts from their shells as much as possible. Dust and adhering branches and leaves on the peanut shells are also shaken off, making the function more comprehensive. A multi-stage screening section further separates the peanuts and shells, ensuring that the peanut kernels fall normally downwards while the shells are collected in a storage box for easy retrieval and removal of any mixed-in peanuts. Furthermore, the sorting section allows for water-based peanut sorting. Hollow or insect-damaged peanuts and their shells float on the water, distinguishing between saturated and large peanuts. The structure is simple and the screening is convenient. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0025] Reference Figure 1-4As shown, a novel screening device for peanuts includes a shell-breaking component 1, a multi-stage screening section 2, and a sorting section 3, arranged sequentially from top to bottom. The shell-breaking component 1 is located below the feed inlet 4, with a first pressure plate 5 above it. Second pressure plates 6 are arranged on the left and right sides inside the shell-breaking component 1. A vibrating element 7 is arranged at the bottom of the shell-breaking component 1. The bottom of the shell-breaking component 1 can communicate with the multi-stage screening section 2. The multi-stage screening section 2 includes multiple inclined screening plates 21. The sorting section 3 is provided with a water inlet 31, a water outlet 32, and a screen 33 hinged to the side wall. A collection area 34 is provided at the bottom and rear of the sorting section 3.
[0026] Among them, such as Figure 1 and Figure 2 As shown, the screening device also includes an outer shell 8, with a hydraulic lifting frame 9 installed on the side wall of the outer shell 8. Its top is connected to the first pressure plate 5, and an electric push rod is installed between the second pressure plate 6 and the inner wall of the shell breaking component 1.
[0027] The outer shell 8 can adopt a square box structure. The vertically arranged box structure facilitates the downward sliding of the peanuts by their own gravity for sorting. Specifically, the first pressure plate 5, as shown... Figure 2 As shown, the bottom of the hydraulic lifting frame 9 can be provided with a placement platform, which is connected to the outer shell 8 as a whole. A support rod is provided protruding upward, and a connecting rod is provided between the support rods. An electric push rod is provided at the top of the connecting rod. The electric push rod can move up and down. The electric push rod is connected to the first pressure plate 5, so that it can press down on the peanuts in the shell-breaking component 1.
[0028] Furthermore, the inner wall of the shell-breaking component 1 is provided with a placement groove 10, and a second pressure plate 6 can be placed in the placement groove 10. The driving component of the electric push rod is located on the outer wall of the shell-breaking component 1, so as to press the peanut a second time and realize the shell-breaking of the peanut.
[0029] In a preferred embodiment, a pressure sensor is provided inside the bottom wall of the shell-breaking component 1, and a pressure sensor is also provided inside the second pressure plate 6. The bottom wall of the shell-breaking component 1 is provided with an opening and closing door.
[0030] Understandably, the pressure sensor is designed to preset the pressure before the peanut shell is broken, thus preventing excessive pressure that could over-squeeze the peanut and damage the kernel inside.
[0031] Furthermore, such as Figure 2 and Figure 3 As shown, the inclined screening plate 21 integrates a vibration motor 11, and the mesh diameter of the inclined screening plate 21 gradually decreases from top to bottom.
[0032] In other words, during use, the upper shell-breaking component 1 opens the peanut shells to a certain extent, and after being squeezed by the first pressure plate 5 and the second pressure plate 6, the peanuts with shells fall onto the surface of the inclined screening plate 21 by opening the bottom door. Under the action of the weight of the peanuts, the peanut shells and peanut kernels are initially separated and screened. Then, the vibration motor 11 of the inclined screening plate further separates the peanut shells and peanut kernels. Under the action of the inclined rolling and the mesh at the bottom, the small pieces of peanut shells and peanut kernels are screened downwards and further screened by multiple inclined screening plates 21 to ensure the separation between peanut kernels and peanut shells.
[0033] In addition, a storage box 12 is provided at the lowest end of the inclined screening plate 21. The storage box 12 adopts a pull-out structure for temporary storage. The function of the storage box 12 is to store peanut shells for easy recycling. To improve the degree of automation, a lifting door can be provided at the entrance of the storage box 12. The top of the lifting door is equipped with an electric push rod structure to drive the lifting door to move vertically, ensuring that the peanut shells enter the storage box 12 normally. It also ensures that the lifting door closes during screening and prevents peanut kernels that need to be screened from entering the storage box 12 during the screening process, thus ensuring the screening effect.
[0034] As a preferred embodiment of this application, such as Figure 2 As shown, a water storage tank 13 is provided on the side of the outer casing 8. The water storage tank 13 is connected to the interior of the sorting section 3. The water inlet 31 and the water outlet 32 are electrically controlled valves.
[0035] It is understandable that the sorting section 3 of this application can be filled with clean water through the water storage tank 13, and the peanut kernels and shells can be sorted by whether they float in the water. Peanuts that are infested with insects or are not mature will float more easily on the surface of the water, while immature and unrefined peanuts will sink to the bottom, thus sorting the peanuts.
[0036] Furthermore, the top of the scooping net 33 is hinged to the top of the sorting section 3, an electric rotating shaft is provided at the connection between the scooping net 33 and the sorting section 3, a sliding door 14 is provided between the sorting section 3 and the multi-stage screening section 2, and the collection area 34 is located below one side of the sliding door 14 and at the bottom of the sorting section 3.
[0037] like Figure 3 and Figure 4 As shown, the sliding door 14 is located on the side close to the scooping net 33, and the sliding door 14 can move up and down through an electric push-pull rod structure at the top. The scooping net 33 can then be rotated through the sliding door 14 and flipped to the collection area 34 to complete the removal and screening of peanuts.
[0038] It should be noted that the length of the scoop net 33 should be long enough, and in order to facilitate the structure of the scoop net 33 and the collection of peanuts on the water surface, the width of the sorting section 3 can be set appropriately. Optionally, two scoop nets 33 can be set to collect peanuts from both sides at the same time. Alternatively, a collection net 15 can be set on the opposite side of the scoop net 33. The collection net 15 can move toward or away from the scoop net 33. The collection net 15 is connected to the electric push rod on the outside of the sorting section 3, so that the collection net 15 can be moved horizontally. In addition, in order to prevent the leakage of internal water, the part of the collection net 15 connected to the electric push rod can be set to protrude above the water surface, and a plumb bob can be set on the lower side.
[0039] Specifically, when screening peanuts, firstly, peanuts in their shells are fed into the inlet 4, and then the first pressure plate 5 and the second pressure plate 6 are activated sequentially to compress the peanuts to a certain extent, causing the peanut shells to open and break. Then, the bottom opening and closing gate is opened, allowing the peanuts to fall into the multi-stage screening section 2 and contact the first inclined screening plate 21. Under the action of gravity, some peanut shells will break and fall off. The unbroken peanut shells and peanuts are then conveyed by the inclined screening plate 21 and vibrated by the inclined screening plate 21, falling to the next inclined screening plate 21 to continue the opening and closing vibration, separating the peanut shells and kernels as much as possible. Finally, the peanuts exit through the last inclined screening plate 21, ensuring that the kernels are separated as much as possible. Smaller peanut shells fall into the sorting section 3, while the remaining shells enter the collection box 12 under the tilting action. The peanut shells are temporarily stored first. The peanuts that fall into the lower sorting section 3 are screened again due to floating and sinking. Then, the scooping net 33 can be activated. The scooping net 33 rotates to scoop up the peanuts floating on the water surface and keeps turning and rotating, so that the sliding door 14 set on the side of the peanut well cover falls into the collection area 34, allowing the peanut shells and unhealthy peanuts to be discharged outside the sorting section 3. Then, the water outlet 32 is opened, allowing the peanuts and water to flow outward. A storage box can be set outside the water outlet 32. A separator net is set inside the storage box to keep the peanuts on the surface of the separator net, while the water continues to flow downward, thus obtaining healthy peanuts.
