Description

Technical Field

[0001] This utility model relates to the field of crop separation tools, and in particular to a corn kernel and silk separation device. Background Technology

[0002] In the processing of fresh corn, after the corn kernels are separated from the corn cob, a small amount of corn silk will get mixed in. This corn silk greatly affects the taste and visual appearance, so it needs to be removed. The commonly used method is to drop the corn kernels from the air and then use a high-speed airflow to blow away the corn silk. However, this method has some problems. If a large number of corn kernels fall in a short period of time, they may block the corn silk, making it impossible to remove the corn silk effectively. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a corn kernel separation device, which can deliver corn kernels more evenly into the separation cylinder, avoid too many corn kernels entering the separation cylinder and causing the corn kernels to not be blown out in time, and make the separation more thorough.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a corn kernel separation device, including a hopper, a conveyor belt and a separation cylinder;

[0005] The hopper is located at the upstream end of the conveyor belt, and a discharge gap is provided between the discharge port of the hopper and the conveyor belt;

[0006] A separation cylinder is provided below the downstream end of the conveyor belt. On the two sides of the middle section of the separation cylinder, there are a wicking window and an air inlet window facing each other. The air inlet window is provided with an air source that blows towards the wicking window.

[0007] During operation, corn kernels with silk are poured into the hopper. Because of the conveyor belt below, when the belt is not rotating, the kernels accumulate at the discharge port, preventing them from flowing downwards. As the conveyor belt rotates, the kernels at the discharge port are continuously removed, and subsequent kernels from the top of the hopper replenish the discharge port. This ensures a more even distribution of kernels on the conveyor belt, preventing uneven accumulation. When the conveyor belt reaches the downstream end, the kernels fall evenly into the separation cylinder. The separation cylinder has an air inlet and a silk outlet. When the kernels and silk pass between these windows, the silk is blown towards the outlet, while the heavier kernels fall directly downwards, thus separating the kernels and silk.

[0008] Preferably, the corn kernel outlet window is connected to an outlet tube, and the bottom inner wall of the outlet tube is set as a slope, with the slope being lower on the side closer to the outlet window. This slope structure allows some of the corn kernels blown into the outlet window to fall back into the separator tube as they land on the slope.

[0009] Preferably, the extrusion tube is a conical tube. This allows the corn that has entered the extrusion window to roll back into the separating tube more effectively.

[0010] Preferably, an air inlet duct is connected to the outside of the air inlet window, and a fan is installed inside the air inlet duct. This facilitates the provision of high-speed airflow.

[0011] Preferably, the hopper's discharge port is slidably fitted with a lifting cylinder, and rollers are provided on both sides of the lower end of the lifting cylinder to contact the conveyor belt. The rollers provide support for the lifting cylinder, and when the conveyor belt rotates, the rollers can adapt to the movement of the conveyor belt by rolling. The lifting cylinder can automatically adjust its vertical height to adapt to the conveyor belt. If it is necessary to increase the height of the lifting cylinder, the rollers with a larger diameter can be replaced.

[0012] Preferably, the lower end of the hopper's discharge port is connected to a discharge cylinder, and the discharge cylinder is fitted with a lifting cylinder. This facilitates the installation of the lifting cylinder.

[0013] Preferably, the lifting cylinder is equipped with a rotating shaft, and the rotating shaft located inside the lifting cylinder is equipped with a disturbance paddle. Both ends of the rotating shaft extend to the outside of the lifting cylinder, and the rollers are disposed at both ends of the rotating shaft. When the conveyor belt drives the rollers to rotate, the rollers will drive the disturbance paddles to rotate through the rotating shaft, preventing material arching at the discharge port of the hopper and ensuring that the corn kernels can fall continuously downwards.

[0014] Preferably, the hopper is equipped with a vibrator. This can further prevent material bridging at the discharge port.

[0015] The beneficial effects of this utility model are:

[0016] This solution uses high-speed airflow to separate corn silk from corn kernels, and a conveyor belt to transport the corn kernels, which can deliver the corn kernels more evenly into the separation cylinder, avoiding too many corn kernels entering the separation cylinder and preventing them from being blown out in time, thus making the separation more thorough.

Detailed Implementation

[0021] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0022] Example

[0023] like Figure 1 As shown, a corn kernel and silk separation device includes a hopper 1, a conveyor belt 7, and a separation cylinder 8; the hopper 1 is located at the upstream end of the conveyor belt 7, and a discharge gap is left between the discharge port of the hopper 1 and the conveyor belt 7; the separation cylinder 8 is arranged below the downstream end of the conveyor belt 7, and the side walls of the middle section of the separation cylinder 8 are provided with silk discharge windows 12 and air inlet windows 9 facing each other, and the air inlet windows 9 are provided with air sources blowing towards the silk discharge windows 12.

[0024] When in use, corn kernels with silk are poured into hopper 1. Because of the conveyor belt 7 below, when the conveyor belt 7 is not rotating, the corn kernels will accumulate at the discharge port, and the corn kernels above hopper 1 will not continuously flow downwards. When the conveyor belt 7 rotates, the corn kernels at the discharge port will be continuously transported away, and subsequent corn kernels from above hopper 1 will be added downwards to the discharge port. This ensures that the corn kernels on the conveyor belt 7 are evenly distributed, avoiding uneven stacking. When the conveyor belt 7 is transported to the downstream end, the kernels fall evenly into the separating cylinder 8. The separating cylinder 8 is equipped with an air inlet window 9 and a silk outlet window 12. Therefore, when the corn kernels and silk pass between the air inlet window 9 and the silk outlet window 12, the silk will be blown towards the silk outlet window 12. Because the corn kernels are heavier, they will fall directly downwards, thus achieving separation of the corn kernels and silk.

[0025] The corn kernel outlet window 12 is connected to the corn kernel outlet cylinder 14. The bottom inner wall of the corn kernel outlet cylinder 14 is set as a slope, and the side of the slope near the corn kernel outlet window 12 is lower. The slope structure can make some of the corn kernels blown into the corn kernel outlet window 12 roll back into the separator cylinder 8 when they fall on the slope.

[0026] The extrusion tube 14 is a conical tube. This allows the corn that has entered the extrusion window 12 to roll back into the separation tube 8 more effectively.

[0027] An air inlet duct 10 is connected to the outside of the air inlet window 9, and a fan is installed inside the air inlet duct 10 to facilitate high-speed airflow. A positive pressure fan 11 is installed in the air inlet duct 10, and a negative pressure fan 13 is installed in the corn silk outlet window 12. Since the negative pressure window contains corn silk, it needs to be cleaned regularly.

[0028] The hopper 1 has a sliding connection between its discharge port and a lifting cylinder 3. Rollers 4 are located on both sides of the lower end of the lifting cylinder 3, which contact the conveyor belt 7. The rollers 4 provide support for the lifting cylinder 3. When the conveyor belt 7 rotates, the rollers 4 adapt to the movement of the conveyor belt 7 and roll accordingly. The lifting cylinder 3 can automatically adjust its height to adapt to the conveyor belt 7. If it is necessary to increase the height of the lifting cylinder 3, the rollers 4 with larger diameters can be replaced.

[0029] The lower end of the discharge port of the hopper 1 is connected to the discharge cylinder 2, and the discharge cylinder 2 is fitted with the lifting cylinder 3. This facilitates the installation of the lifting cylinder 3.

[0030] The lifting cylinder 3 is fitted with a rotating shaft 5, and a disturbance paddle is installed on the rotating shaft 5 located inside the lifting cylinder 3. Both ends of the rotating shaft 5 extend to the outside of the lifting cylinder 3, and rollers 4 are installed at both ends of the rotating shaft 5. When the conveyor belt 7 drives the rollers 4 to rotate, the rollers 4 will drive the disturbance paddle to rotate through the rotating shaft 5, avoiding material arching at the discharge port of the hopper 1 and ensuring that the corn kernels can fall continuously downwards.

[0031] The hopper 1 is equipped with a vibrator. This can further prevent material bridging at the discharge port.

[0032] The beneficial effects of this utility model are:

[0033] This solution uses high-speed airflow to separate corn silk from corn kernels, and uses a conveyor belt 7 to transport the corn kernels, which can deliver the corn kernels more evenly into the separation cylinder 8, avoiding too many corn kernels entering the separation cylinder 8 and causing the corn kernels to not be blown out in time.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
