Description

Technical Field

[0001] This utility model relates to the field of rice appearance quality inspection technology, and in particular to an arranging device for rice appearance quality inspection. Background Technology

[0002] In the field of rice processing and quality control, rice appearance quality inspection is a crucial step in ensuring product quality and enhancing market competitiveness. This mainly involves classifying rice grades by testing indicators such as grain shape, color, breakage rate, and chalkiness. To achieve accurate inspection, randomly piled rice must first be neatly arranged in a uniform posture to ensure that each grain can be clearly and individually seen within the inspection equipment's field of view. Therefore, the rice arranging device has become a core pre-processing unit in rice appearance quality inspection systems, widely used in rice processing plants, grain testing institutions, and food quality supervision departments. Especially in automated, high-precision inspection production lines, the performance of the arranging device directly determines the inspection efficiency and accuracy of the results.

[0003] Currently, mainstream rice sorting devices in the industry use a vibration source placed under the sorting platform or conveyor track. Through continuous or intermittent vibration, the disordered rice grains are gradually moved towards a designated area and attempted to align under the combined action of inertia and friction. While this can break the disordered state of the rice to some extent and provide a basis for subsequent testing, it has significant shortcomings in terms of sorting accuracy, efficiency, and stability.

[0004] First, the existing single-vibration sorting device has low sorting efficiency. Since it relies solely on the force generated by vibration to guide the movement of rice, the rice is prone to "piling up and congestion" or "reverse shifting" in the sorting area. Some rice will remain in a disorderly rolling state and cannot quickly enter the preset position required for testing, resulting in a long sorting time, which is difficult to match the pace of high-speed testing production lines. Second, in order to achieve a certain sorting effect, the existing device needs to maintain a high vibration frequency and amplitude, which not only generates significant noise pollution, but may also cause some fragile rice to be damaged secondary during vibration, destroying the original appearance of the rice and further affecting the authenticity of the test data. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sorting device for inspecting the appearance quality of rice.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rice sorting device for inspecting the appearance quality of rice, comprising a base, a follower plate at the upper end of the base, springs fixedly installed at the four corners of the top of the follower plate, hoppers fixedly installed at the upper ends of the four springs, a sorting plate installed at the bottom of the inner side of the hopper, and multiple slots with holes adapted to the size of rice on the surface of the sorting plate.

[0007] The upper end of the base is provided with a bidirectional piston cylinder. Concave plates are fixedly installed on both sides of the bidirectional piston cylinder. Shafts are rotatably installed on the inner sides of the two concave plates. The two sides of the shafts extend through to the outer sides of the concave plates and are fixedly installed with T-shaped rods. Concave plates are fixedly installed on both sides of the bottom of the follower plate. Inclined guide grooves are opened through both sides of the bottom of the concave plates. The two T-shaped rods are slidably disposed on the inner side of the inclined guide grooves.

[0008] Preferably, the inclined guide grooves on the two concave plates are V-shaped. In the initial state, the T-shaped rod of the bidirectional piston cylinder is located in the middle of the inclined guide groove, and the follower plate maintains a parallel posture.

[0009] Preferably, the bottom of the bidirectional piston cylinder is fixedly mounted with a mounting base by screws, and the mounting base is fixedly connected to the upper middle part of the base.

[0010] Preferably, a buffer rubber ring is fixedly installed at the bottom of the follower plate, and the bottom of the buffer rubber ring is fixedly installed on the upper surface of the base. The buffer rubber ring is rectangular and has a continuous serrated bend shape.

[0011] Preferably, a vibrating motor is provided on the side of the hopper, and the vibrating motor is fixed to the side wall of the hopper by a motor frame.

[0012] Preferably, multiple magnetic attractors are fixedly installed at the inner bottom of the hopper, and the bottom of the aligning plate is made of metal and connected to the magnetic attractors.

[0013] Preferably, multiple feed troughs are evenly provided at both ends of the inner side of the hopper, and the rice inside the hopper is concentrated on the inner side of the feed troughs when the hopper is tilted.

[0014] Preferably, a cylinder controller is provided on the inner side of the base, and the bidirectional piston cylinder is connected to the cylinder controller through pipelines and wires.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model utilizes a bidirectional piston cylinder that extends and retracts simultaneously at one end, causing a T-shaped rod to slide within a V-shaped inclined guide groove formed by two concave plates. This enables the follower plate and hopper to swing back and forth. Combined with a vibrating motor driving the hopper to vibrate at high frequency, the rice, guided by the swing and dispersed by the vibration, quickly enters the single-grain hole groove of the aligning plate along the trough. This effectively solves the problems of rice accumulation and congestion and low aligning efficiency in existing single vibration devices, significantly improving the aligning speed to adapt to high-speed testing production lines, and ensuring uniform rice posture, thus laying the foundation for accurate testing.

[0017] 2. This utility model sets a rectangular continuous sawtooth bent buffer rubber ring between the follower plate and the base. On the one hand, the buffer rubber ring uses the damping characteristics of rubber to absorb the vibration energy transmitted by the vibration motor and weaken the transmission of vibration to the base. On the other hand, its sawtooth bent structure can deform synchronously with the left and right reciprocating swing of the follower plate, preventing stress concentration caused by rigid connection, reducing the noise pollution problem caused by high vibration of existing devices, reducing the wear of vibration on equipment parts, avoiding loosening of parts, extending service life, and ensuring the authenticity of test data.

[0018] 3. This utility model adopts a magnetic connection structure. Utilizing the properties of magnetic adsorption and separation, operators can easily separate the entire tray from the main body of the device without the need for tools to disassemble traditional connectors such as screws and clips. Compared to traditional rigid screw and clip connections, this avoids the problem of screws loosening and clips wearing due to long-term vibration, which can lead to tray displacement and affect the accuracy of rice feeding. Under normal conditions, it can stably adsorb and ensure the working posture of the entire tray, while allowing for rapid separation during sampling, improving the convenience of equipment maintenance and the stability of the entire tray.

[0033] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0035] Example: Reference Figures 1-5 A rice sorting device for inspecting the appearance quality of rice includes a base 1, a follower plate 2 at the upper end of the base 1, springs 301 fixedly installed at the four corners of the top of the follower plate 2, a hopper 3 fixedly installed at the upper end of each of the four springs 301, a sorting plate 4 installed at the bottom of the inner side of the hopper 3, and multiple holes and slots adapted to the size of the rice on the surface of the sorting plate 4.

[0036] The upper end of the base 1 is provided with a bidirectional piston cylinder 701. Concave plates 702 are fixedly installed on both sides of the bidirectional piston cylinder 701. Shafts 703 are rotatably installed on the inner side of the two concave plates 702. The two sides of the shafts 703 extend through to the outer side of the concave plates 702 and are fixedly installed with T-shaped rods 704. Concave plates 8 are fixedly installed on both sides of the bottom of the follower plate 2. Inclined guide grooves 801 are opened through both sides of the bottom of the concave plates 8. The two T-shaped rods 704 are slidably disposed on the inner side of the inclined guide grooves 801 respectively.

[0037] Specifically: In actual use, spring 301 connects follower plate 2 and hopper 3. With the movement of follower plate 2, hopper 3 can continuously generate a shaking effect at the upper end of follower plate 2. hopper 3 guides the flow of rice through inner trough 402. With the combination of swaying and vibration, the rice is pre-processed in a row. The holes and slots of the rowing plate 4 are physically limited to ensure that the rice is in a uniform posture for inspection, providing a basis for subsequent testing.

[0038] When the device is in operation, the bidirectional piston cylinder 701 extends and retracts, driving the concave plate 702 and the shaft 703 to move, causing the T-shaped rod 704 to slide along the guide groove and push the follower plate 2 to swing. The follower plate 2 drives the hopper 3 to swing synchronously through the spring 301. The rice gathers along the trough 402 towards the aligning plate 4 and falls into the slot to complete the alignment. This solves the problems of low efficiency and rice accumulation of a single vibration device, ensuring stable and efficient alignment and laying the foundation for accurate detection.

[0039] The inclined guide grooves 801 on the surfaces of the two concave plates 8 are V-shaped. In the initial state, the T-shaped rod 704 of the bidirectional piston cylinder 701 is located in the middle of the inclined guide groove 801. At this time, the follower plate 2 maintains a parallel posture. The bottom of the bidirectional piston cylinder 701 is fixedly installed with a mounting seat 7 by screws. The mounting seat 7 is fixedly connected to the upper middle part of the base 1.

[0040] Specifically: In the initial state, the T-shaped rod 704 is located in the middle of the guide groove. When the bidirectional piston cylinder 701 extends or retracts, the T-shaped rod 704 can slide to both sides of the inclined guide groove 801 by equal distances, ensuring that the angle of inclination of the follower plate 2 to both sides is consistent, and further ensuring the balance of the swing motion.

[0041] The inclined guide groove 801 on the surface of the concave plate 2 provides a clear sliding trajectory for the T-shaped rod 704. When the bidirectional piston cylinder 701 drives the T-shaped rod 704 to slide, the groove wall of the inclined guide groove 801 can convert the linear motion of the T-shaped rod 704 into a lateral thrust on the concave plate 2, thereby pushing the follower plate 2 to tilt and swing. The shaft 703 can rotate flexibly around its own axis, avoiding the T-shaped rod 704 from getting stuck due to rigid tension when sliding in the guide groove, while ensuring that the T-shaped rod 704 always moves in contact with the guide groove wall. In addition, the symmetrical structure of the inclined guide groove 801 can make the force even when the T-shaped rod 704 slides to both sides, avoiding the sticking or tilt angle deviation when the follower plate 2 swings, and ensuring that the rice inside the hopper 3 can flow stably along the feed trough 402 when it swings with the follower plate 2.

[0042] A buffer rubber ring 6 is fixedly installed at the bottom of the follower plate 2. The bottom of the buffer rubber ring 6 is fixedly installed on the upper surface of the base 1. The buffer rubber ring 6 is rectangular and has a continuous serrated bend shape. A vibration motor 5 is provided on the side of the hopper 3. The vibration motor 5 is fixed to the side wall of the hopper 3 through the motor frame. The buffer rubber ring 6 can absorb the vibration energy transmitted from the vibration motor 5 to the follower plate 2 and the base 1, weaken the transmission of vibration to the overall structure of the device, avoid the loosening of the connection parts between the base 1 and the follower plate 2 due to long-term high-frequency vibration, reduce the noise pollution generated by vibration, improve the working environment, and the continuous serrated bend shape can undergo flexible deformation synchronously with the left and right reciprocating swing of the follower plate 2. When the follower plate 2 tilts to one side, the bend of the rubber ring on the corresponding side is stretched and the other side is compressed. When the follower plate 2 tilts in the opposite direction, it deforms in the opposite direction. The elastic deformation buffers the impact load between the follower plate 2 and the base 1 during the swing process, prevents the stress concentration generated by the rigid connection from damaging the parts, and ensures the stability of the swing motion of the follower plate 2.

[0043] Multiple magnetic attractors 401 are fixedly installed at the bottom of the hopper 3. The bottom of the aligning plate 4 is made of metal and is connected to the magnetic attractors 401. Multiple feed troughs 402 are evenly opened at both ends of the inner side of the hopper 3. When the hopper 3 is tilted, the rice inside is concentrated inside the feed troughs 402. A cylinder controller is provided on the inner side of the base 1. A bidirectional piston cylinder 701 is connected to the cylinder controller through pipes and wires.

[0044] Specifically: When the hopper 3 enters the tilted state along with the moving plate 2, the rice in the hopper 3 will naturally gather into the feed trough 402 under the action of gravity and swaying inertia, avoiding the rice from being scattered or piled up in the hopper 3 in a disorderly manner; the uniform layout of the feed trough 402 can divert the rice to different channels, so that the rice moves towards the aligning plate 4 in a dispersed state, effectively improving the aligning efficiency.

[0045] Multiple magnets 401 fixed at the bottom of the hopper 3 form a stable magnetic connection with the metal aligning plate 4. On the one hand, the magnetic connection enables the aligning plate 4 to be positioned and installed quickly without the need for traditional connectors such as screws and clips, simplifying the assembly process. On the other hand, when it is necessary to clean or replace the aligning plate 4, only external force needs to be applied to overcome the magnetic force to remove the aligning plate 4, which is convenient to operate. At the same time, it avoids the problem of the aligning plate 4 shifting due to the loosening of traditional connectors under long-term vibration, ensuring the stability of the aligning plate 4 during operation, and thus ensuring the accuracy of rice entering the trough.

[0046] The working principle of this utility model is as follows: When using it, first pour the rice to be tested into the hopper 3, then start the device, and the cylinder controller and the vibration motor 5 on the inner side of the base 1 start working synchronously.

[0047] The cylinder controller controls the action of the bidirectional piston cylinder 701 through pipelines and wires. Because one end of the bidirectional piston cylinder 701 extends while the other end contracts synchronously, its extension and retraction process drives the two fixed concave plates 702 and the shaft 703 rotatably connected to the inner side of the concave plates 702 to perform reciprocating linear motion. The T-shaped rods 704 extending from both ends of the shaft 703 to the outer side of the concave plates 702 slide along the groove wall within the inclined guide groove 801 of the bottom concave plate 8 of the follower plate 2 as the shaft 703 moves. When the T-shaped rod 704... 04 When sliding from the middle of the guide groove to one side, it will generate a lateral thrust on the concave plate 8, pushing the follower plate 2 to tilt to the corresponding side. When the bidirectional piston cylinder 701 extends and retracts in the opposite direction, and the T-shaped rod 704 slides to the other side of the guide groove, the follower plate 2 tilts to the other side, thereby driving the hopper 3 connected above the follower plate 2 by the four corner springs 301 to swing back and forth. Under the action of the swing inertia, the rice in the hopper 3 will gather along the trough 402 on the inner side of the hopper 3 towards the alignment plate 4 at the bottom of the hopper 3.

[0048] At the same time, the vibrating motor 5, which is fixed to the side of the hopper 3 by the motor frame, is started, which drives the hopper 3 to generate high-frequency micro-vibration, breaking the accumulation and jamming state that may occur during the rice gathering process, so that the rice falls accurately into the single-grain hole groove opened on the surface of the aligning plate 4, completing the orderly alignment of the rice, and preparing for the subsequent appearance quality inspection equipment to grab the clear appearance information of individual grains of rice.

[0049] When it is necessary to replace the sorting plate 4 for sampling, after shutting down the device, simply apply an external force greater than the attraction force of the magnetic attraction 401 at the bottom of the hopper 3 to the sorting plate 4, which has a metal bottom, to remove it from the hopper 3. After cleaning or replacement, reattach the sorting plate 4 to the bottom of the hopper 3 and fix it with the attraction force of the magnetic attraction 401. Then, the device can be restarted to perform rice sorting operations.
