A screening device for grain production and processing

Abstract

This utility model provides a screening device for grain production and processing, relating to the technical field of screening devices. It includes a mounting base and a barrel, a screening component disposed inside the barrel, a screening barrel disposed inside the barrel, vibrating components disposed inside both ends of the screening barrel, and a cross plate disposed at the end of the screening barrel. The screening component can drive the screening barrel to rotate and screen simultaneously, while also cleaning the inside of the screening barrel. When the end roller contacts the protrusion of the vibrating ring, it drives the top sliding spring to compress. After disengaging, the spring releases its elastic potential energy to strike the vibrating ring, causing the screening barrel to vibrate and dislodging material clogging the screen holes. This synergistic mechanism of "rotational cleaning + vibration unclogging" reduces the risk of clogging at its source, ensuring a smooth and efficient screening process.

Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a screening device for grain production and processing. Background Technology

[0002] When processing grains, it is necessary to remove the outer husk of the grain. For example, the processing of rice requires the removal of the outer husk. After processing, the grain also needs to be screened to remove smaller impurities.

[0003] A search revealed Chinese patent number CN222789740U, which discloses a screening device for grain production and processing. The device includes a base, with an mounting cylinder fixedly connected to the upper surface of the base. A rotating hole is provided on the side of the mounting cylinder, and a screening cylinder is rotatably connected to the inner wall of the rotating hole. The side of the screening cylinder is rotatably connected to the inner wall of the mounting cylinder. Screening holes are provided on the surface of the screening cylinder. An electric push rod can be activated, pushing an arc-shaped plate downwards. A top rod is inserted into the screening hole to push out any stuck grain. Furthermore, an insert rod is inserted into a countersunk hole to position the mounting plate, thereby fixing the screening cylinder in a specific location and ensuring accurate insertion of the top rod into the screening hole for easy cleaning.

[0004] The aforementioned screening devices have poor cleaning and anti-clogging efficiency, lacking an effective real-time cleaning and vibration-based unblocking mechanism. Materials easily accumulate and clump on the screen wall or clog the screen holes, causing the screening channel to gradually narrow. This not only significantly reduces screening efficiency and requires frequent shutdowns for manual cleaning, interrupting processing continuity, but also easily leads to uneven material screening due to screen hole blockage, affecting product quality stability. At the same time, manual cleaning is time-consuming and labor-intensive, increasing labor costs, and long-term blockage will exacerbate screen wear, shorten equipment lifespan. Frequent start-ups, shutdowns, and maintenance also increase energy consumption. Utility Model Content

[0005] The purpose of this utility model is to provide a screening device for grain production and processing, which can solve the problems of poor cleaning and anti-clogging efficiency of the above-mentioned screening devices, lack of effective real-time cleaning and vibration anti-clogging mechanism, easy accumulation and agglomeration of materials on the screen wall or blockage of screen holes, resulting in the gradual narrowing of the screening channel. This not only greatly reduces screening efficiency and requires frequent shutdowns for manual cleaning, interrupting the continuous processing, but also easily causes uneven screening of materials due to screen hole blockage, affecting the stability of product quality. At the same time, manual cleaning is time-consuming and labor-intensive, increasing labor costs, and long-term blockage will aggravate screen wear and shorten the service life of equipment. Frequent start-ups, shutdowns and maintenance will also increase energy consumption.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a screening device for grain production and processing, comprising a mounting base and a barrel, and further comprising: A screening component is disposed on the inner side of the barrel body; A screening bucket is disposed on the inner side of the bucket body; Vibrating elements are installed on the inner sides of both ends of the screening barrel; A cross plate is provided at the end of the screening barrel; The screening component can drive the screening barrel to rotate and screen, while also cleaning the inside of the screening barrel.

[0007] In a preferred embodiment, the mounting bracket is fixedly disposed on the outer side of one end of the barrel body; The first bevel gear is rotatably mounted on the inner side of one end of the mounting bracket; A connecting shaft is fixedly mounted on one side of the first bevel gear, and one end of the connecting shaft is connected to one side of the cross plate. The second bevel gear is rotatably mounted on the inner side of the other end of the mounting bracket; The third bevel gear is rotatably mounted on the inner side of the bottom end of the mounting bracket; A connecting frame is fixedly mounted on one side of the second bevel gear, and the outer end of the connecting frame is connected to one side of the screening barrel; A connecting plate is fixedly installed on the inner side of the cross plate.

[0008] In a preferred embodiment, the third bevel gear meshes with both the first bevel gear and the second bevel gear.

[0009] In a preferred embodiment, a cleaning brush is fixedly provided on one side of the connecting plate, and the cleaning brush is used to clean the inside of the screening barrel.

[0010] In a preferred embodiment, a motor is mounted on one side of the mounting bracket, and the outer side of the motor's main shaft is connected to the inner side of the third bevel gear.

[0011] In a preferred embodiment, the vibrating ring is fixedly disposed on the inner sides of both ends of the screening barrel, and the cross plate is disposed on the inner side of the vibrating ring; The top head is slidably disposed on the inner side of the end of the cross plate.

[0012] In a preferred embodiment, a spring is fixedly provided on the inner side of the end of the cross plate, and the outer side of the end of the spring is connected to one side of the top head.

[0013] In a preferred embodiment, a roller is rotatably provided on the inner side of the end of the top head.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In use, this utility model's screening device effectively solves the clogging problem during material screening through a dual anti-clogging design, ensuring continuous processing. After the motor is started, the screening barrel and cross plate rotate relative to each other through gear meshing transmission, causing the inner connecting plate to move synchronously in the opposite direction. The cleaning brush cleans the inner wall of the screening barrel in real time, preventing material from accumulating and clumping on the screen wall. At the same time, when the cross plate rotates, the end roller contacts the protrusion of the vibrating ring, which drives the top sliding spring to compress. After the contact is broken, the spring releases its elastic potential energy to hammer the vibrating ring, causing the screening barrel to vibrate and dislodging the material clogging the screen holes. This synergistic mechanism of "rotation cleaning + vibration clogging" reduces the risk of clogging from the root and ensures a smooth and efficient screening process. Attached Figure Description

[0017] 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.

[0018] Example 1: Please see Figure 1 - Figure 6 This embodiment provides a screening device for grain production and processing that is easy to clean and prevents clogging. The specific idea is as follows: A screening device for grain production and processing includes a mounting base 1 and a barrel 101. The screening device for grain production and processing also includes a screening barrel 2 and screening components.

[0019] The screening bucket 2, which performs the screening function, is located inside the bucket body 101.

[0020] The screening component is located inside the barrel 101.

[0021] The screening component can drive the screening barrel 2 to rotate and screen, while also cleaning the inside of the screening barrel 2.

[0022] As some examples, in this embodiment, the screening component includes: The mounting bracket 201, which serves as the installation bracket, is fixedly connected to the outer side of one end of the barrel body 101.

[0023] The first bevel gear 202, which serves as a connector, is rotatably connected to the inner side of one end of the mounting bracket 201.

[0024] The connecting shaft 203, which serves a fixing function, is fixedly connected to one side of the first bevel gear 202.

[0025] In addition, one end of the connecting shaft 203 is fixedly connected to one side of the cross plate 3.

[0026] The second bevel gear 204, which serves as a connecting element, is rotatably connected to the inner side of the other end of the mounting bracket 201.

[0027] The third bevel gear 205, which serves as a connector, is rotatably connected to the inner side of the bottom end of the mounting bracket 201.

[0028] In addition, the third bevel gear 205 is meshed with the first bevel gear 202 and the second bevel gear 204 respectively.

[0029] The connecting frame 206, which plays a connecting role, is fixedly connected to one side of the second bevel gear 204, and the outer side of the end of the connecting frame 206 is fixedly connected to one side of the screening barrel 2.

[0030] The connecting plate 207, which serves as a connector, is fixedly connected to the inner side of the cross plate 3.

[0031] It should be noted that a cleaning brush 208 is fixedly connected to one side of the connecting plate 207. The cleaning brush 208 is used to clean the inside of the screening barrel 2.

[0032] Among them, a motor 209 is installed on one side of the mounting bracket 201 that plays a driving role, and the outer side of the main shaft of the motor 209 is connected to the inner side of the third bevel gear 205.

[0033] It should be noted that the screening barrel 2 and the connecting plate 207 rotate relative to each other. This relative rotation increases the cleaning efficiency of the cleaning brush 208 on the inner wall of the screening barrel 2.

[0034] Example 2: Please see Figure 1 - Figure 6 This embodiment provides a screening device for grain production and processing that facilitates further cleaning. The specific concept is as follows: A screening device for grain production and processing includes a mounting base 1 and a barrel 101. The screening device for grain production and processing also includes a cross plate 3 and a vibrating element.

[0035] The cross plate 3, which plays a vibratory role, is located on the inner side of the barrel body 101.

[0036] The vibrating element is located on the inner side of the end of the screening barrel 2.

[0037] As some examples, in this embodiment, the vibrating element includes: The vibrating ring 301 is fixedly connected to the inner sides of both ends of the screening barrel 2, and the cross plate 3 is set inside the vibrating ring 301.

[0038] The top head 302 is slidably connected to the inner side of the end of the cross plate 3.

[0039] Among them, a spring 304 is fixedly connected to the inner side of the end of the cross plate 3, and the outer side of the end of the spring 304 is fixedly connected to one side of the top head 302.

[0040] Among them, a roller 303 is rotatably connected to the inner side of the end of the top head 302.

[0041] It should be noted that by intermittently contacting the protrusions on the inner side of the vibrating ring 301 with the roller 303, the inner side of the vibrating ring 301 can be hammered, thereby driving the screening barrel 2 to vibrate to a certain extent.

[0042] Working principle: When using the device, the user can open one side of the barrel 101 and inject the material into the inner side of the screening barrel 2. The user can then start the motor 209, which drives the third bevel gear 205 to rotate. The rotation of the third bevel gear 205 will drive the first bevel gear 202 and the second bevel gear 204, which are meshed with it, to rotate relative to each other. The rotation of the first bevel gear 202 will drive the connecting shaft 203 to rotate, and the rotation of the connecting shaft 203 will drive the cross plate 3 to rotate. The rotation of the second bevel gear 204 will drive the screening barrel 2 to rotate through the connecting frame 206. This will cause the connecting plate 207 on the inner side of the screening barrel 2 and the cross plate 3 to rotate relative to each other. The cleaning brush 208 can then clean the inner wall of the screening barrel 2 to prevent clogging.

[0043] This screening device effectively solves the clogging problem during material screening through a dual anti-clogging design, ensuring continuous processing. After starting the motor 209, the screening barrel 2 and the cross plate 3 rotate relative to each other through gear meshing transmission, causing the inner connecting plate 207 to move synchronously in the opposite direction. The cleaning brush 208 cleans the inner wall of the screening barrel 2 in real time, preventing material from accumulating and clumping on the screen wall. At the same time, when the cross plate 3 rotates, the end roller 303 contacts the protrusion of the vibrating ring 301, which drives the top head 302 to slide and compress the spring 304. After disengaging, the spring 304 releases elastic potential energy to hammer the vibrating ring 301, causing the screening barrel 2 to vibrate and shake out the material clogging the screen holes. This synergistic mechanism of "rotation cleaning + vibration clogging" reduces the risk of clogging from the root and ensures a smooth and efficient screening process.

[0044] When the cross plate 3 rotates, it indirectly contacts the protrusion on the inner side of the vibrating ring 301 through the roller 303 at its end. When in contact, it will press against the outer side of the roller 303, thereby driving the top head 302 to slide towards the inner side of the cross plate 3. While the top head 302 slides, it will compress the spring 304 and store the elastic potential energy of the spring 304. At the same time, the roller 303 will rotate when in contact with the vibrating ring 301 to reduce friction. When the roller 303 disengages from the protrusion of the vibrating ring 301, the spring 304 will release the elastic potential energy and hammer the vibrating ring 301, thereby driving the screening barrel 2 to vibrate and shake out the blockage in the screen hole of the screening barrel 2.

[0045] 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 other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
