Description

Technical Field

[0001] This utility model relates to the technical field of gorgon fruit screening devices, and in particular to an airflow screening device for grading gorgon fruit. Background Technology

[0002] The airflow sieving device for grading water chestnuts is an automated sorting equipment based on the interaction of airflow and gravity. It generates a controllable airflow through a fan, causing water chestnut particles of different sizes and weights to fall into different collection ports due to differences in buoyancy in the airflow field, thereby achieving precise grading. This device does not require a screen and can efficiently and continuously divide water chestnuts into multiple grades. It has the advantages of high sorting accuracy, good automation, and minimal damage to materials, and is widely used in modern water chestnut processing.

[0003] However, in the actual use of airflow screening devices, if the feeding speed is too fast or the material layer is too thick, the materials will overlap and collide in the airflow, making it impossible for light materials to be effectively blown up, and heavy materials will also change their falling trajectory due to collisions. This will eventually lead to impure grading and mixing of materials of different grades. Existing equipment mostly uses vibrating feeders, but their feeding speed is easily affected by factors such as the amount of material and changes in material moisture, making it difficult to keep constant. Operators often need to monitor and adjust frequently, which is time-consuming, labor-intensive, and ineffective. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the overlapping and collision of materials in the airflow makes it difficult for lightweight materials to be effectively blown, resulting in the mixing of materials of different grades after screening. Therefore, an airflow screening device for grading water chestnuts is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An airflow sieving device for grading water chestnuts includes a sieving box with a feed channel fixedly connected to it. It also includes guide plates symmetrically connected within the feed channel, wherein a discharge zone is formed between adjacent guide plates. A discharge roller is rotatably mounted within the discharge zone, and equidistant feeding troughs are arranged on the discharge roller. When the discharge roller rotates, the material is guided into the sieving box by the feeding troughs. An anti-blocking component is also provided within the feed channel, positioned above the guide plates, to guide the material into the discharge zone.

[0007] Preferably, a guide plate, an interceptor plate one, and an interceptor plate two are fixedly connected inside the screening box, and a guide strip is fixedly connected to the guide plate. The guide plate, interceptor plate one, and interceptor plate two form a screening air duct. When the material falls into the screening air duct, the flow direction of the material is changed by the airflow.

[0008] Preferably, a fan is fixedly connected to the screening box, a connecting pipe is fixedly installed at the air outlet end of the fan, an exhaust pipe is fixedly connected at the air outlet end of the connecting pipe, and the end of the exhaust pipe extends to the bottom of the guide plate and is connected to the screening air duct. When the fan is working, the airflow passes through the connecting pipe and is discharged to the screening air duct through the exhaust pipe, thereby changing the direction of material flow.

[0009] Preferably, the anti-clogging component includes a support frame fixedly connected to the guide plate. The support frame has diversion ports arranged at equal intervals, and a flow zone is formed between the support frame and the guide plate. A rotating roller is rotatably connected in the flow zone. Agitators are arranged in a ring on the rotating roller, and the agitators are respectively installed in the diversion ports. When the rotating roller rotates, the agitators apply pressure to the material above the support frame and in the flow zone and strike the material.

[0010] Preferably, the rotating shafts of both the rotating roller and the feeding roller extend outward through the feeding channel, and the driving end of the feeding roller is fixedly connected to a drive motor, the other end of the feeding roller is fixedly connected to a drive wheel, and the controlled end of the rotating roller is fixedly connected to a driven wheel, and the driven wheel and the drive wheel are connected by belt drive. When the drive motor works, the feeding roller rotates and causes the drive wheel to drive the belt and the driven wheel to rotate, thereby driving the rotating roller to rotate.

[0011] Preferably, the screening box is fixedly connected to a bracket and an inspection port, and the inspection port is installed on the left side of the guide plate. The screening box is provided with a first discharge port and a second discharge port. The first discharge port is connected to the screening channel, and the second discharge port is installed at the rear end of the first discharge port for grading and screening the water chestnut.

[0012] Compared with the prior art, this utility model provides an airflow sieving device for grading water chestnuts, which has the following beneficial effects:

[0013] 1. This airflow screening device for grading water chestnuts achieves quantitative and constant-speed material conveying through a guide plate, a uniformly rotating feed roller, and an arc-shaped feed trough. Stable feeding ensures that the material entering the sorting airflow is in a uniform thin layer, allowing each water chestnut to be fully blown and sorted by the airflow, thereby significantly improving the purity and efficiency of grading and effectively solving the problem of decreased grading accuracy caused by fluctuations in feeding speed.

[0014] 2. This airflow sieving device for grading water chestnuts, through the combined use of a support frame, rotating rollers, and stirring rods, ensures the continuity of feeding on the one hand, and on the other hand, it can break up the sticky water chestnut lumps during the feeding stage, ensuring the dispersion of the feeding, laying the most solid foundation for high-precision air separation, thereby improving the final sorting purity.

[0015] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model utilizes a feeding roller, a conveying trough, a support frame, a rotating roller, and a stirring rod in combination. On the one hand, it can break up the clumps of water chestnuts to prevent the clumps from affecting the air separation quality. On the other hand, the conveying trough and the feeding roller work together to ensure that each water chestnut is fully blown and separated by the airflow, thereby improving the effect of water chestnut grading and screening.

[0023] Example:

[0024] Reference Figures 1-4An airflow sieving device for grading water chestnuts includes a sieving box 1 with a feed channel 13 fixedly connected to it. It also includes guide plates 2 symmetrically connected within the feed channel 13, forming a discharge zone between adjacent guide plates 2. A discharge roller 5 is rotatably installed within the discharge zone, and equidistant conveying troughs 51 are arranged on the discharge roller 5. When the discharge roller 5 rotates, the material is guided into the sieving box 1 by the conveying troughs 51. An anti-blocking component is installed within the feed channel 13, positioned above the guide plates 2, to guide the material into the discharge zone.

[0025] In this embodiment, by setting the cooperative structure of the guide plate 2 and the feed roller 5, the material is diverted and buffered before entering the screening box 1, which effectively prevents the accumulation and blockage of material. The equidistant design of the feed trough 51 ensures that the material can enter the screening box 1 at a constant and uniform flow rate, forming a thin and uniform material curtain, providing stable input conditions for subsequent airflow screening, and significantly improving the accuracy and consistency of grading.

[0026] Reference Figure 2 and Figure 3 As shown, a guide plate 6, an interceptor plate 1 and an interceptor plate 2 71 are fixedly connected inside the screening box 1. A guide strip 61 is fixedly connected to the guide plate 6. The guide plate 6, the interceptor plate 1 and the interceptor plate 2 71 form a screening air duct. When the material falls into the screening air duct, the flow direction of the material is changed by the airflow.

[0027] In this embodiment, the screening air duct formed by the guide plate 6, the first interceptor plate 7, and the second interceptor plate 71 can extend the residence time of the material in the airflow. The flow direction of the water chestnut can be finely adjusted by the guide strip 61, so that water chestnut particles of different weights and sizes produce significant differences in their movement trajectories in the air duct. This structure uses the continuous action of airflow to achieve multi-stage sorting, which improves the efficiency and accuracy of grading, while avoiding mechanical damage to the skin of the water chestnut caused by traditional vibrating screening.

[0028] Reference Figure 2 and Figure 3 As shown, a blower 8 is fixedly connected to the screening box 1. A connecting pipe 81 is fixedly installed at the air outlet end of the blower 8. An exhaust pipe 82 is fixedly connected to the air outlet end of the connecting pipe 81. The end of the exhaust pipe 82 extends to the bottom of the guide plate 6 and is connected to the screening air duct. A dustproof plate 9 is fixedly connected to the air inlet end of the blower 8. When the blower 8 is working, the airflow passes through the connecting pipe 81 and is discharged to the screening air duct through the exhaust pipe 82, thereby changing the direction of material flow.

[0029] In this embodiment, the blower 8 precisely guides the airflow to the bottom of the screening duct through the connecting pipe 81 and the exhaust pipe 82, forming a uniform airflow field from bottom to top. This ensures that the airflow can fully act on the falling material, effectively blowing up light impurities and immature particles, while heavy water chestnuts fall along a predetermined path. The dustproof plate 9 can prevent dust from the outside of the equipment from entering the screening box 1, effectively maintaining the cleanliness of the screened water chestnuts. At the same time, it can extend the service life of the blower 8, making the airflow distribution of the entire system uniform, with low energy consumption and stable and reliable sorting effect.

[0030] Refer to Figure 3 and Figure 4 As shown, the anti-clogging component includes a support frame 3 fixedly connected to the guide plate 2. Diverting ports 31 are arranged at equal intervals on the support frame 3, and a flow zone is formed between the support frame 3 and the guide plate 2. A rotating roller 4 is rotatably connected in the flow zone. Agitating rods 41 are arranged in a ring on the rotating roller 4, and the agitating rods 41 are respectively installed in the diverting ports 31. When the rotating roller 4 rotates, the agitating rods 41 apply pressure to the material above the support frame 3 and in the flow zone and strike the material.

[0031] In this embodiment, the anti-blocking component disperses the material in advance through the diversion port 31 on the support frame 3 to avoid concentrated accumulation. At the same time, it can prevent the phenomenon of arching blockage caused by mutual friction of the gluten during the feeding process. The rotating roller 4 drives the stirring rod 41 to rotate continuously in the flow zone, applying a gentle squeezing and impacting force to the material, effectively breaking up any possible lumps and adhesion, and ensuring that the material enters the feeding zone smoothly.

[0032] Reference Figure 1 and Figure 2 As shown, the rotating shafts of both the rotating roller 4 and the feeding roller 5 extend outward through the feeding channel 13. The driving end of the feeding roller 5 is fixedly connected to the driving motor 10, and the other end of the feeding roller 5 is fixedly connected to the driving wheel 101. The controlled end of the rotating roller 4 is fixedly connected to the driven wheel 102, and the driven wheel 102 and the driving wheel 101 are connected by a belt 103. When the driving motor 10 is working, the feeding roller 5 rotates and the driving wheel 101 drives the belt 103 and the driven wheel 102 to rotate, thereby driving the rotating roller 4 to rotate.

[0033] In this embodiment, the rotating roller 4 and the feeding roller 5 are mechanically linked through the drive wheel 101, the driven wheel 102 and the belt 103 to ensure the synchronization of anti-blocking and feeding actions. The drive motor 10 can achieve the coordinated work of the entire feeding channel 13 with a single point drive. The structure is compact and the transmission efficiency is high, which effectively reduces the manufacturing cost and operation complexity of the equipment.

[0034] Reference Figure 3As shown, a bracket 11 and an inspection port 12 are fixedly connected to the screening box 1, and the inspection port 12 is installed on the left side of the guide plate 6. The screening box 1 is provided with a discharge port 14 and a discharge port 2 15. The discharge port 14 is connected to the screening channel, and the discharge port 2 15 is installed at the rear end of the discharge port 14 for grading and screening the water chestnut.

[0035] In this embodiment, the bracket 11 provides stable support for the screening box 1, ensuring the stability of the equipment during operation. The inspection port 12 facilitates the cleaning and maintenance of the screening air duct, improving the operability and service life of the equipment. The discharge port 14 and discharge port 25 correspond to different grades of water chestnuts, and the layout is reasonable, so that the sorted materials can be collected in an orderly manner, further improving the grading efficiency and practicality of the whole machine.

[0036] In this invention, at the start of operation, the drive motor 10 starts, driving the feeding roller 5 and the rotating roller 4 to rotate synchronously through the transmission system. The water chestnut material to be graded is fed from above the feeding channel 13, first falling above the support frame 3 and into the flow zone. Then, the rotating roller 4 drives the stirring rod 41 to rotate continuously, stirring and combing the material, effectively breaking up any lumps and agglomerates. The material is then evenly dispersed through the diversion port 31 on the support frame 3 to prevent blockage. The pre-treated material slides down the inclined surface of the guide plate 2 into the feeding zone, forming a uniform distribution along the width of the entire feeding channel 13. The rotating feeding roller 5 feeds the material quantitatively and discretely into the screening box 1 through the conveying trough 51 at a constant flow rate. A uniform material curtain is formed. At this time, the blower 8 starts and the generated airflow is evenly sent into the screening air duct inlet at the bottom of the screening box 1 through the connecting pipe 81 and the exhaust pipe 82. During the process of the material falling under the action of gravity, it comes into full contact with the airflow from bottom to top. Particles of different weights and sizes are subjected to different aerodynamic resistance in the airflow field, resulting in different motion trajectories: the lighter immature particles, impurities, etc. are subjected to airflow force greater than their weight and are blown to a farther position by the airflow, eventually passing through the interceptor plate 1 and the interceptor plate 2 71 and being discharged from the discharge port 2 15. Meanwhile, the qualified gorgon fruit particles of moderate weight fall basically in the vertical direction under the balance of airflow and gravity and are discharged from the discharge port 1 14.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
