Description

Technical Field

[0001] This invention specifically relates to a rice quality analysis device. Background Technology

[0002] As living standards continue to improve, people have higher requirements for the quality of their daily diet. In order to establish an objective and quantitative evaluation system based on data in the rice purchasing, processing, storage and sales process, rice quality analyzers have emerged. These instruments integrate optical, electrical and hardware and software technologies, aiming to achieve rapid and accurate detection of the appearance of rice.

[0003] In terms of optical systems, rice quality analyzers mostly use blue-white light source solutions. This solution suffers from the asymmetry of the front and rear optical paths, leading to inconsistent camera images and significantly increasing the system's recognition complexity. Furthermore, when identifying rice germ characteristics, the blue-white light source is easily confused with lesion features, resulting in a low recognition rate. Additionally, the feeding sections of these analyzers are mainly of two types: chute-type and conveyor-type. Chute-type analyzers typically use a single material trough structure, with the trough installation angle mostly at 60°, resulting in poor material dispersion. Moreover, the high speed of the material makes it difficult to maintain a consistent posture when reaching the shooting viewpoint. Conveyor-type analyzers, limited by size and height, mostly use single-view shooting. Rice grains tend to tumble in the air after being thrown from the conveyor, affecting image quality, especially interfering with shape recognition. Furthermore, the conveyor itself easily retains rice grains or dust, requiring high levels of cleaning and maintenance. Therefore, we propose a rice quality analysis device. Summary of the Invention

[0004] The purpose of this invention is to provide a rice quality analysis device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rice quality analysis device, comprising:

[0006] A frame on which a control box is fixed;

[0007] A dust collection assembly is installed at the top of the control box for material feeding;

[0008] An analysis component is disposed inside the rack, and the analysis component has a cleaning component for cleaning its interior;

[0009] A feeding assembly is disposed at the lower end of the dust removal assembly to vibrately convey material into the inside of the analysis assembly;

[0010] The analytical assembly includes an analytical housing, a glass plate, a lampshade, and a lamp plate. The lampshade is fixed to the middle of the inner side of the analytical housing and is arc-shaped. The inner surface of the lampshade has a diffuse reflection coating. The lamp plate is disposed inside the lampshade to correspond to the diffuse reflection coating. The lampshade has a glass plate that is isolated from the material.

[0011] Preferably, the analysis component further includes a background plate and a camera. The camera is disposed at the lower inner side of the analysis housing, and the inner side of the lampshade has a through hole corresponding to one end of the camera for taking pictures. The background plate is located below the lampshade.

[0012] Preferably, the outer wall of the glass plate has a mounting frame fixed to the analytical housing, and rubber is provided between the inner side of the mounting frame and the glass plate.

[0013] Preferably, the cleaning assembly includes a cleaning bracket, a rodless cylinder, a connecting plate, a rotating shaft, and a cleaning strip. The cleaning bracket is fixed to the inner side of the frame, and a rodless cylinder is provided at one end of the inner side of the cleaning bracket. One end of the connecting plate is connected to the rodless cylinder, and the other end is connected to the cleaning strip through the rotating shaft. A torsion spring is sleeved on the rotating shaft to press the cleaning strip down.

[0014] Preferably, the cleaning strip is symmetrically arranged in two places along the connecting plate.

[0015] Preferably, the dust removal assembly includes a guide housing, a feed pipe, and a suction pipe. The guide housing is fixed to the upper surface of the control box. A feed inlet is provided on one side of the guide housing, and an inclined plate corresponding to the feed inlet is provided on the inner side of the guide housing to disperse the material. A feed pipe communicating with the feeding assembly is provided at the lower end of the guide housing, and a suction pipe communicating with the interior is provided at one end of the upper surface of the guide housing.

[0016] Preferably, the feeding assembly includes a vibrator and a second guide trough. The vibrator is fixed to the lower end of the dust removal assembly, and the vibrator is provided with a first guide trough for guiding the material. The second guide trough is provided at one end of the first guide trough to guide the material into the inside of the analysis assembly.

[0017] Preferably, the installation angle α of the second guide trough is ≤45°, and multiple material feeding channels that separate the material are evenly distributed along the short side of the inner side of the second guide trough.

[0018] Preferably, multiple lamp panels are provided along the arc length of the lampshade, and the lamp panels are all-white light lamp panels.

[0019] Preferably, the lower surface of the analysis component is provided with a discharge element for discharging material along the height direction.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) This invention avoids the inconsistent photographic effects caused by the asymmetry of the light path in traditional blue and white light sources by using an arc-shaped lampshade, a diffuse reflection coating and a full white light panel. Only one light source is used for illumination. Due to the limitations of the structure and position of the light panel, there are shadows. This device adjusts the position of the light panel so that the light source used for dual-path photography is full white light. Furthermore, by using reflective uniform lighting, it is beneficial to improve the uniformity of illumination, improve the brightness consistency of rice in different postures, reduce the false recognition caused by shadows by the camera, and improve the detection effect.

[0022] (2) By setting up a first guide trough, a second guide trough with a small installation angle and multiple feeding channels, the traditional method of setting only one material guide trough with a large installation angle is avoided, which is not conducive to the material spreading during the falling process. This device can ensure that the material is spread evenly, slow down the falling speed, ensure that the material has enough distance and time to adjust its posture, ensure the consistency of the posture when the material is photographed and recognized, and improve the ability to distinguish small color differences when photographing and recognizing in the later stage.

[0023] (3) By setting up a rodless cylinder, connecting plate, rotating shaft and cleaning strip, the traditional air blowing cleaning method is not effective and manual cleaning is time-consuming and laborious. This device can quickly clean the impurities attached to the glass plate by scraping, and the cleaning effect is good. Moreover, the reciprocating movement of the rodless cylinder can clean two glass plates at the same time, ensuring good cleaning efficiency. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-7 The present invention provides a technical solution: a rice quality analysis device, comprising:

[0034] Frame 1, with control box 2 fixed on frame 1;

[0035] Dust removal component 3 is installed at the top of control box 2 for material feeding;

[0036] Analysis component 4 is located inside rack 1, and analysis component 4 has cleaning component 6 for cleaning its interior;

[0037] It facilitates automatic cleaning, reducing the inconvenience of manual cleaning;

[0038] The feeding component 5 is located at the lower end of the dust removal component 3 to vibrate and convey materials to the inside of the analysis component 4.

[0039] The analysis component 4 includes an analysis housing 41, a glass plate 42, a lampshade 43 and a lamp plate 46. The lampshade 43 is fixed to the middle of the inner side of the analysis housing 41 and is arc-shaped. The inner surface of the lampshade 43 has a diffuse reflection coating. The lamp plate 46 is disposed inside the lampshade 43 to correspond to the diffuse reflection coating. The lampshade 43 has a glass plate 42 that is isolated from the material.

[0040] It facilitates reflective uniform lighting, effectively improves the uniformity of lighting, and avoids the inconsistent shooting effect caused by the asymmetry of the light path of traditional blue and white light sources. By setting two lamp covers 43 symmetrically, the shadows during material imaging can be effectively reduced, ensuring the brightness of rice is consistent under different postures, and significantly improving the detection stability and recognition accuracy of features such as whiteness, dark rice and blemishes.

[0041] Preferably, the analysis component 4 further includes a background plate 44 and a camera 45. The camera 45 is disposed at the lower end of the inner side of the analysis housing 41, and the inner side of the lamp cover 43 is provided with a through hole corresponding to one end of the camera 45 for taking pictures. The background plate 44 is located below the lamp cover 43.

[0042] This facilitates the photographing of materials located between the two lampshades 43 for comparative analysis.

[0043] Preferably, the outer wall of the glass plate 42 has a mounting frame 47 fixed to the analytical housing 41, and rubber is provided between the inner side of the mounting frame 47 and the glass plate 42;

[0044] The rubber is preferably EPDM rubber, which helps to improve the sealing of the glass plate 42 after installation, reduce the impurities adhering to the surface of the rice from entering the inside of the lampshade 43, and can be replaced and maintained later by disassembling the glass plate 42.

[0045] Preferably, the cleaning component 6 includes a cleaning bracket 61, a rodless cylinder 62, a connecting plate 63, a rotating shaft 64, and a cleaning strip 65. The cleaning bracket 61 is fixed to the inner side of the frame 1, and a rodless cylinder 62 is provided at one end of the inner side of the cleaning bracket 61. One end of the connecting plate 63 is connected to the rodless cylinder 62, and the other end is connected to the cleaning strip 65 through the rotating shaft 64. A torsion spring is sleeved on the rotating shaft 64 to press the cleaning strip 65 down.

[0046] The rodless cylinder 62 drives the connecting plate 63 and the cleaning strip 65 to reciprocate, which can scrape off impurities attached to the surface of the glass plate 42. This mechanical cleaning method is more thorough than traditional air blowing cleaning, and the torsion spring keeps the cleaning strip 65 in contact with the glass surface, improving the cleaning effect and efficiency.

[0047] Preferably, the cleaning strip 65 is symmetrically arranged in two places along the connecting plate 63;

[0048] The rodless cylinder 62 can clean two glass plates 42 simultaneously in a single reciprocating motion, significantly improving cleaning efficiency and reducing downtime for maintenance.

[0049] Preferably, the dust removal assembly 3 includes a guide housing 31, a feed pipe 34, and a suction pipe 33. The guide housing 31 is fixed to the upper surface of the control box 2. A feed inlet 32 ​​is provided on one side of the guide housing 31, and an inclined plate corresponding to the feed inlet 32 ​​is provided on the inner side of the guide housing 31 to disperse the material. The lower end of the guide housing 31 has a feed pipe 34 that communicates with the feeding assembly 5. A suction pipe 33 that communicates with the interior is provided at one end of the upper surface of the guide housing 31.

[0050] The inclined plate surface can be equipped with protrusions to improve the material dispersion effect. When combined with the external fan of the dust suction pipe 33, it can effectively remove impurities such as rice husks and dust during the feeding stage, reduce interference in the subsequent identification process, and improve the accuracy of the detection results.

[0051] Preferably, the feeding assembly 5 includes a vibrator 51 and a second guide chute 53. The vibrator 51 is fixed to the lower end of the dust removal assembly 3, and a first guide chute 52 for guiding the material is provided on the vibrator 51. The second guide chute 53 is provided at one end of the first guide chute 52 to guide the material into the inside of the analysis assembly 4.

[0052] Vibration conveying facilitates the smooth and orderly transport of materials, and helps to further disperse materials during movement, preventing accumulation.

[0053] Preferably, the installation angle α of the second guide trough 53 is ≤45°, and multiple material feeding channels that separate the material are evenly distributed along the short side of the inner side of the second guide trough 53.

[0054] It effectively slows down the falling speed of the material, so that the rice spreads out evenly when it leaves the feed trough. This is beneficial for its attitude adjustment in the air, improves the consistency of attitude during imaging, and enhances the ability to identify subtle features such as color difference and spots.

[0055] Preferably, multiple lamp panels 46 are provided along the arc length of the lampshade 43, and the lamp panels 46 are all-white light lamp panels;

[0056] The light panel 46 is combined with a diffuse reflection coating to form uniform and soft multi-angle lighting, further eliminating local dark areas and reflections, ensuring that rice in different positions and postures can obtain consistent lighting conditions, and improving the adaptability and stability of the detection system.

[0057] Preferably, the lower surface of the analysis component 4 is provided with a discharge element 7 for discharging material along the height direction;

[0058] It facilitates the smooth discharge of materials after identification and analysis, and is easy to connect with the recycling system to realize automatic material return and reprocessing, thereby improving the overall automation level and operational continuity of the equipment.

[0059] The working principle and usage process of this invention are as follows: During use, rice material enters the inner side of the guide housing 31 through the feed inlet 32. The material is dispersed by the inclined plate inside the guide housing 31. Simultaneously, the suction pipe 33 can be connected to an external fan to suck up and discharge impurities from the material. Under gravity, the material falls onto the first guide trough 52 through the guide pipe 34. The vibrator 51 vibrates the material, causing it to move along the length of the first guide trough 52. The material is then guided into the analysis component 4 through the second guide trough 53. The installation angle between the second guide trough 53 and the horizontal direction is less than 45°, which helps reduce the rolling speed of the material and facilitates the adjustment of the rice material's posture. The light emitted by the lamp plate 46 is pure white light. Through the diffuse reflection coating, it reflects to form a uniform multi-angle light source, creating a uniform illumination effect on the material and ensuring consistent brightness of rice material in different postures. This facilitates stable detection of whiteness, dark rice, and disease spots. After identification, the rice material passes through the discharge component 7 and enters the raw grain section for further identification and removal in the next process.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
