Description

Technical Field

[0001] This utility model belongs to the field of sorting machine technology, specifically, it relates to a raw material rotary sorting machine. Background Technology

[0002] Fruit sorting machines are automated grading devices that classify fruits by detecting size, appearance, and internal quality parameters. Early equipment primarily relied on physical sorting based on size differences. However, with technological advancements, AI data algorithms, near-infrared detection, and image recognition technologies are widely used, enabling precise detection of indicators such as appearance defects, sugar content, and moldy core. As of 2025, intelligent sorting systems have achieved fully automated operation, with a processing capacity of 2-3 tons per hour, and support data visualization and customized modules. This equipment has significantly improved sorting efficiency and accuracy in agriculture, logistics, and food processing.

[0003] Chinese invention patent CN107744935A discloses a simple rotary garlic slice sorting machine. It features an upper and lower garlic-slicing plate that can rotate relative to each other. The upper and lower garlic-slicing holes on the upper and lower plates have the same diameter and are positioned correspondingly. When the upper and lower garlic-slicing plates are rotated, the overlapping area between the upper and lower garlic-slicing holes changes accordingly. To sort garlic slices of different sizes, simply rotate the upper plate to a suitable angle. This garlic slice sorting machine can sort garlic slices of different sizes.

[0004] Although this sorting machine can sort raw materials according to size, it cannot control the size of the screening holes well during the screening process, making it impossible to adjust the size of the screening holes accurately and quickly according to actual needs. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that although the sorting machine can sort raw materials according to size, it cannot effectively control the size of the screening holes during the screening process, thus making it impossible to accurately and quickly adjust the size of the screening holes according to actual needs, the present invention adopts the following technical solution.

[0007] A rotary raw material separator includes a screening cylinder. An outer mounting edge is fixedly connected to the outer wall of the screening cylinder. Support legs are detachably connected to the bottom two sides of the outer mounting edge. An upper mounting cover is detachably connected to the upper end of the screening cylinder. A feeding trough is provided on the upper mounting cover. A third screening plate, a second screening plate, and a first screening plate are arranged from top to bottom inside the screening cylinder. There is a certain distance between the third screening plate, the second screening plate, and the first screening plate. The third screening plate is detachably connected to the inner wall of the screening cylinder. The second screening plate and the first screening plate are rotatably connected to the inner wall of the screening cylinder. The third screening plate, the second screening plate, and the first screening plate are provided with multiple large screening holes. The second screening plate and the first screening plate are provided with multiple medium screening holes. The first screening plate is provided with multiple small screening holes.

[0008] Preferably, the outer wall of the first screening plate is provided with multiple conical grooves, and the outer wall of one side support leg is detachably connected to a first drive motor. The rotating end of the first drive motor is fixedly connected to a bevel gear, which meshes with the first drive motor.

[0009] Preferably, the bottom of the third screening plate is provided with a plurality of first arc-shaped grooves, the bottom of the second screening plate is provided with a plurality of second arc-shaped grooves, the first arc-shaped grooves are longer than the second arc-shaped grooves, the upper end of the first screening plate is fixedly connected with a second sliding plate inserted into the second arc-shaped groove, and the upper end of the second screening plate is fixedly connected with a first sliding plate inserted into the first arc-shaped groove.

[0010] Preferably, a second drive motor is detachably connected to the upper end of the mounting top cover. The rotating end of the second drive motor passes through the mounting top cover and is detachably connected to a drive shaft. The drive shaft passes through the first screening plate, the second screening plate, and the third screening plate. A scraping inclined plate is detachably connected to the outer wall of the drive shaft above the first screening plate, the second screening plate, and the third screening plate.

[0011] Preferably, the outer wall of the scraping inclined plate in the direction of rotation is provided with an inclined surface.

[0012] Preferably, the scraping inclined plate is provided with multiple material distribution grooves, each material distribution groove being narrower on the inside near the inclined surface and wider on the other side.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By pouring the raw material into the screening cylinder, the large, medium, and small screening holes are arranged vertically from top to bottom. This allows the raw material that can pass through the small screening holes on the first screening plate to fall downwards for collection, while the raw material that meets the requirements of the large screening holes falls above the second screening plate, and the raw material that meets the requirements of the medium screening holes falls above the first screening plate. At this point, rotating the first screening plate changes the small screening holes on it to medium screening holes, allowing the raw material above the first screening plate to be discharged downwards and collected. Rotating the first screening plate again changes the medium screening holes to large screening holes, and rotating the second screening plate changes the medium screening holes on it to large screening holes, allowing the raw material that meets the requirements of the large screening hole size to fall downwards for collection. This allows for the batch discharge of raw materials of different sizes, making screening more convenient.

[0015] 2. The first drive motor rotates, driving the bevel gear to rotate. The bevel gear meshes with the bevel tooth groove, causing the first screening plate to rotate. When the first screening plate rotates, the second sliding plate slides from one end of the second arc-shaped groove to the other end. At this time, the screening hole on the first screening plate is aligned with the screening hole on the second screening plate. The first screening plate rotates again, causing the second screening plate to rotate inside the first arc-shaped groove via the first sliding plate. This allows the third screening plate, the second screening plate, and the screening hole on the first screening plate to be aligned, thereby automatically changing the filtration size.

[0016] 3. The rotation of the second drive motor drives each scraper tilting plate to rotate, thereby agitating the raw materials above the first screening plate, the second screening plate and the third screening plate, resulting in better screening effect and faster speed.

[0017] 4. The raw materials fall onto the inclined scraper plate via the inclined surface, which can lift the raw materials and improve the screening effect. The material distribution trough allows smaller raw materials above the inclined scraper plate to fall first and larger ones to fall later, thus allowing smaller raw materials to be screened first and further improving screening efficiency.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0029] like Figure 1 The diagram shown is a schematic diagram of a preferred embodiment of the present invention. The raw material rotary sorting machine of this embodiment includes a screening cylinder 100. An outer mounting edge 101 is fixedly connected to the outer wall of the screening cylinder 100. Support legs 102 are detachably connected to the bottom two sides of the outer mounting edge 101. An upper mounting cover 103 is detachably connected to the upper end of the screening cylinder 100. A feeding trough 104 is provided on the upper mounting cover 103. In this embodiment, the raw material to be screened is placed into the interior of the screening cylinder 100 for screening through the feeding trough 104.

[0030] like Figure 3As shown, this is a schematic diagram of the screening component structure in this embodiment. Inside the screening cylinder 100, from top to bottom, are arranged a third screening plate 205, a second screening plate 204, and a first screening plate 200. A certain distance exists between the third screening plate 205, the second screening plate 204, and the first screening plate 200. The third screening plate 205 is detachably connected to the inner wall of the screening cylinder 100, while the second screening plate 204 and the first screening plate 200 are rotatably connected to the inner wall of the screening cylinder 100. The third screening plate 205, the second screening plate 204, and the first screening plate 200 are provided with multiple large screening holes 206, the second screening plate 204 and the first screening plate 200 are provided with multiple medium screening holes 207, and the first screening plate 200 is provided with multiple small screening holes 208. In this embodiment, when raw materials are poured into the screening cylinder 100, the large screening holes 206, the medium screening holes 207, and the small screening holes 208 are connected. The holes 208 are vertical from top to bottom, allowing raw materials that pass through the small holes 208 on the first screening plate 200 to fall downwards for collection, while raw materials that meet the requirements of the large holes 206 fall above the second screening plate 204, and raw materials that meet the requirements of the medium holes 207 fall above the first screening plate 200. At this time, rotating the first screening plate 200 changes the small holes 208 on the first screening plate 200 to the medium holes 207, thereby allowing the raw materials above the first screening plate 200 to fall downwards and be collected. Rotating the first screening plate 200 again changes the medium holes 207 to the large holes 206, and rotating the second screening plate 204 changes the medium holes 207 on the second screening plate 204 to the large holes 206, thereby allowing raw materials that meet the size of the large holes 206 to fall downwards for collection. This allows raw materials of different sizes to be discharged in batches, making screening more convenient.

[0031] like Figure 2 as well as Figure 3As shown, this is a schematic diagram of the rotating assembly structure in this embodiment. The outer wall of the first screening plate 200 is provided with multiple conical grooves 201. A first drive motor 202 is detachably connected to the outer wall of one side support leg 102. A bevel gear 203 is fixedly connected to the rotating end of the first drive motor 202, meshing with the first drive motor 202. The bottom of the third screening plate 205 is provided with multiple first arc-shaped grooves 209, and the bottom of the second screening plate 204 is provided with multiple second arc-shaped grooves 210. The first arc-shaped grooves 209 are longer than the second arc-shaped grooves 210. A second sliding plate 212 inserted into the second arc-shaped groove 210 is fixedly connected to the upper end of the first screening plate 200, and a first sliding plate 212 inserted into the first arc-shaped groove 209 is fixedly connected to the upper end of the second screening plate 204. In this embodiment, the sliding plate 211 is driven by the rotation of the first drive motor 202, which drives the bevel gear 203 to rotate. The meshing of the bevel gear 203 with the bevel tooth groove 201 causes the first screening plate 200 to rotate. When the first screening plate 200 rotates, the second sliding plate 212 slides from one end of the second arc-shaped slide groove 210 to the other end. At this time, the screening hole 207 on the first screening plate 200 is aligned with the screening hole 206 on the second screening plate 204. The first screening plate 200 rotates again, causing the second screening plate 204 to rotate inside the first arc-shaped slide groove 209 through the first sliding plate 211. This allows the third screening plate 205, the second screening plate 204, and the screening hole 206 on the first screening plate 200 to be aligned, thereby automatically changing the filtration size.

[0032] like Figure 4 As shown, this is a schematic diagram of the stirring assembly structure in this embodiment. The upper end of the mounting top cover 103 is detachably connected to a second drive motor 300. The rotating end of the second drive motor 300 passes through the mounting top cover 103 and is detachably connected to a drive shaft 304. The drive shaft 304 passes through the first screening plate 200, the second screening plate 204, and the third screening plate 205. The outer wall of the drive shaft 304 above the first screening plate 200, the second screening plate 204, and the third screening plate 205 is detachably connected to a scraping inclined plate 301. In this embodiment, the rotation of the second drive motor 300 drives each scraping inclined plate 301 to rotate, thereby stirring the raw materials above the first screening plate 200, the second screening plate 204, and the third screening plate 205, resulting in better screening effect and faster speed.

[0033] like Figure 4 As shown, the outer wall of the scraping inclined plate 301 in the direction of rotation is provided with an inclined surface 303. In this embodiment, the raw material falls above the scraping inclined plate 301 through the inclined surface 303 and then falls down, thereby achieving the effect of lifting the raw material and making the screening effect better.

[0034] like Figure 4As shown, the scraping inclined plate 301 is provided with a plurality of material distribution grooves 302. Each material distribution groove 302 is narrower inside near the inclined surface 303 and wider on the other side. In this embodiment, by setting the material distribution grooves 302, the smaller raw materials located above the scraping inclined plate 301 can fall first and the larger ones fall later, thereby enabling the smaller raw materials to be screened first and further improving the screening efficiency.

[0035] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
