Technical Field
[0001] This utility model relates to the field of rice processing line technology, and in particular to a feeding device for a rice processing line that is easy to install. Background Technology
[0002] A rice processing line is a general term for a series of equipment and processes used to process paddy into rice. It covers all aspects from receiving, cleaning, hulling, milling, grading to packaging of paddy. It is a complete production line that transforms paddy into edible rice. In the rice processing process, the feeding device is an important component of the processing line.
[0003] Regarding existing related technologies, the inventors believe that they often have the following drawbacks: the feeding devices of traditional rice processing lines are usually cumbersome and complicated to install, requiring a lot of time and manpower, which increases the installation cost. Due to the complicated process, daily maintenance and repair are inconvenient, reducing maintenance efficiency. Moreover, most of them lack a vibration screening structure for rice, which makes it impossible to effectively separate impurities in the rice, causing these impurities to enter the subsequent processing stages along with the rice. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that the existing feeding devices for rice processing lines are often complicated to install, inconvenient to maintain, and most lack vibration screening function, which makes it impossible to effectively separate impurities and affects the quality of subsequent processing. Therefore, we propose a feeding device for rice processing lines that is easy to install.
[0005] To achieve the above objectives, this application adopts the following technical solution: a feeding device for a rice processing line that is easy to install, comprising a supporting base plate; a U-shaped support frame is fixed to the top of the supporting base plate; a storage box is provided inside the U-shaped support frame; a material gathering pipe is fixed to the top of the storage box; a screening box is provided on the top of the supporting base plate; grooves are provided at both ends of the top of the U-shaped support frame; trapezoidal blocks are provided inside the grooves; a connecting rod is fixed to one side of the trapezoidal block; a circular plate is fixed to one end of the connecting rod; a pull plate is slidably connected to the surface of the connecting rod; fixing blocks are fixed to both ends of the pull plate; a fixing hole for cooperating with the fixing block is provided on one side of the U-shaped support frame; a moving plate is slidably connected to both ends of the trapezoidal block; a locking block is fixed to one side of the moving plate; connecting blocks are fixed to both ends of the storage box; and locking grooves for cooperating with the locking blocks are provided at both ends of the connecting blocks.
[0006] Preferably, a first spring is slidably connected to the surface of the connecting rod, one end of the first spring is fixed to the circular plate, and the other end of the first spring is fixed to the pull plate.
[0007] Preferably, limit rods are fixed on both sides of the groove, and the surface of the limit rods is slidably connected to the interior of the movable plate.
[0008] Preferably, a second spring is slidably connected to the surface of the limiting rod, one end of the second spring is fixed to the moving plate, and the other end of the second spring is fixed to the groove.
[0009] Preferably, a first motor is provided on one side of the U-shaped support frame, and a rotating shaft is rotatably connected inside the U-shaped support frame. One end of the rotating shaft is fixed to the output end of the first motor, and four stirring plates are fixed on the surface of the rotating shaft. The stirring plates are distributed in a circle around the rotating shaft.
[0010] Preferably, both sides of the screening box are fixed with fixing plates, a rotating rod is rotatably connected inside the screening box, a second motor is provided on one side of the screening box, the output end of the second motor is fixed to one end of the rotating rod, a screen is slidably connected inside the screening box, cams are fixed to both ends of the rotating rod, and a third spring is fixed to both ends of the top of the fixing plate, with the other end of the third spring fixed to the screen.
[0011] Preferably, vertical rods are fixed at both ends of the top of the fixing plate, and the surface of the vertical rods is slidably connected to the inside of the screen.
[0012] The technical effects and advantages of this utility model are as follows: In this invention, by pulling the pull plate outward, the fixing block is driven away from the inside of the fixing hole. Pulling the connecting rod drives the trapezoidal block to move. The two sides of the trapezoidal block will pull the moving plate to move, so that it drives the card block into the inside of the card slot. Through the above settings, the U-shaped support frame and the storage box can be installed quickly, which greatly shortens the installation time. There are no complicated steps, which reduces the manpower, material resources and time costs required during the installation process. It also facilitates the daily maintenance and repair of the device and improves maintenance efficiency. In this invention, a second motor drives a rotating rod to rotate a cam. The cam presses against the screen, causing the screen to vibrate up and down with the help of a third spring. During the vibration process, the rice entering the screening box can be screened to separate impurities or broken rice, ensuring the purity of the feed. At the same time, the vibration can speed up the feeding speed of the rice, avoid screen blockage, improve screening efficiency, and provide high-quality raw materials for subsequent processing.

[0016] Reference Figures 1-5As shown, this utility model provides a technical solution: a feeding device for a rice processing line that is easy to install, including a supporting base plate 1; a U-shaped support frame 2 is fixed to the top of the supporting base plate 1, a storage box 3 is provided inside the U-shaped support frame 2, a material gathering pipe 4 is fixed to the top of the storage box 3, a screening box 5 is provided on the top of the supporting base plate 1, grooves 6 are provided at both ends of the top of the U-shaped support frame 2, trapezoidal blocks 7 are provided inside the grooves 6, a connecting rod 8 is fixed to one side of the trapezoidal block 7, a circular plate 9 is fixed to one end of the connecting rod 8, a pull plate 10 is slidably connected to the surface of the connecting rod 8, fixing blocks 11 are fixed to both ends of the pull plate 10, a fixing hole 12 is provided on one side of the U-shaped support frame 2 to cooperate with the fixing block 11, and both ends of the trapezoidal block 7 are slidably connected.

The two ends of the connecting blocks 15 are provided with slots 16 that cooperate with the locking blocks 14. By pulling the pull plate 10 outward, the fixing block 11 is driven away from the inside of the fixing hole 12. The connecting rod 8 is pulled to move the trapezoidal block 7. The two sides of the trapezoidal block 7 will pull the movable plate 13 to move, so that it drives the locking block 14 into the inside of the slot 16. Through the above settings, the U-shaped support frame 2 and the storage box 3 can be quickly installed, which greatly shortens the installation time. There is no need for complicated steps, which reduces the manpower, material resources and time costs required during the installation process. It also facilitates the daily maintenance and repair of the device and improves maintenance efficiency.
[0017] Reference Figure 2 As shown in this embodiment: a first spring 17 is slidably connected to the surface of the connecting rod 8. One end of the first spring 17 is fixed to the circular plate 9, and the other end of the first spring 17 is fixed to the pull plate 10. By setting the structure of the first spring 17, when the limit on the connecting rod 8 is released, the tensile force of the first spring 17 can quickly pull the pull plate 10 back to the initial position, thereby driving the fixing block 11 to leave the interior of the fixing hole 12, thereby releasing the limit.
[0018] Reference Figure 3 As shown in this embodiment: Limiting rods 18 are fixed on both sides of the groove 6. The surface of the limiting rods 18 is slidably connected to the inside of the moving plate 13. By setting the structure of the limiting rods 18, a guiding effect is provided for the movement of the moving plate 13, ensuring that the moving plate 13 moves along the prescribed route.
[0019] Reference Figure 3 As shown in this embodiment: a second spring 19 is slidably connected to the surface of the limiting rod 18. One end of the second spring 19 is fixed to the moving plate 13, and the other end of the second spring 19 is fixed to the groove 6. By setting the structure of the second spring 19, it can provide buffering and restoring force when the moving plate 13 moves. When the locking block 14 is inserted into the inside of the locking slot 16, the second spring 19 can generate elastic force for the moving plate 13, which can help the locking block 14 to be in the closed state.
[0020] Reference Figure 4 As shown in this embodiment: a first motor 20 is provided on one side of the U-shaped support frame 2, and a rotating shaft 21 is rotatably connected inside the U-shaped support frame 2. One end of the rotating shaft 21 is fixed to the output end of the first motor 20. Four stirring plates 22 are fixed on the surface of the rotating shaft 21. The stirring plates 22 are distributed in a circle around the rotating shaft 21. The first motor 20 drives the rotating shaft 21 to rotate the stirring plates 22, which can stir the rice in the storage box 3. The stirring process can prevent the rice from piling up and clumping, so that the rice is fed evenly and the continuity and stability of the feeding are guaranteed.
[0021] Reference Figure 1 and Figure 5 As shown in this embodiment: Fixing plates 23 are fixed on both sides inside the screening box 5. A rotating rod 24 is rotatably connected inside the screening box 5. A second motor 25 is installed on one side of the screening box 5. The output end of the second motor 25 is fixed to one end of the rotating rod 24. A screen 26 is slidably connected inside the screening box 5. Cams 27 are fixed to both ends of the rotating rod 24. A third spring 28 is fixed to both ends of the top of the fixing plate 23. The other end of the third spring 28 is fixed to the screen 26. The second motor 25 drives the rotating rod 24 to rotate the cams 27. The cams 27 squeeze the screen 26, causing the screen 26 to vibrate up and down with the cooperation of the third spring 28. During the vibration process, the rice entering the screening box 5 can be screened, separating impurities or broken rice to ensure the purity of the feed. At the same time, the vibration can speed up the feeding speed of the rice, avoid clogging of the screen 26, improve screening efficiency, and provide high-quality raw materials for subsequent processing.
[0022] Reference Figure 1 and Figure 5 As shown in this embodiment: vertical rods 29 are fixed at both ends of the top of the fixed plate 23. The surface of the vertical rods 29 is slidably connected to the inside of the screen 26. By setting the structure of the vertical rods 29, the sliding of the screen 26 is guided, ensuring that the screen 26 remains stable during vibration and avoiding poor screening effect or structural damage due to shaking. At the same time, the vertical rods 29 cooperate with the third spring 28 to further enhance the stability and regularity of the vibration of the screen 26.
[0023] Working principle: By pulling the pull plate 10 outward, the user moves the fixing block 11 away from the inside of the fixing hole 12, and pulls the connecting rod 8 to move the trapezoidal block 7. The two sides of the trapezoidal block 7 will pull the moving plate 13 to move, causing it to move the locking block 14 into the inside of the slot 16. Through the above settings, the U-shaped support frame 2 and the storage box 3 can be quickly installed, greatly shortening the installation time. There are no complicated steps, reducing the manpower, material resources and time costs required during the installation process, and facilitating the daily maintenance and repair of the device, thus improving maintenance efficiency. By setting the structure of the first spring 17, when the limit on the connecting rod 8 is released, the tension of the first spring 17 can quickly pull the pull plate 10 back to the initial position, thereby moving the fixing block 11 away from the inside of the fixing hole 12, thus releasing the limit. By setting the structure of the limit rod 18, the movement of the moving plate 13 is guided, ensuring that the moving plate 13 moves along the prescribed route. By setting the structure of the second spring 19, the movement of the moving plate 13 is buffered and reset. When the locking block 14 is inserted... When the second spring 19 is inside the slot 16, it can generate elastic force for the moving plate 13, which can help the locking block 14 to be in the closed state. The first motor 20 drives the rotating shaft 21 to drive the stirring plate 22 to rotate, which can stir the rice in the storage box 3. The stirring process can prevent the rice from piling up and clumping, so that the rice is fed evenly, ensuring the continuity and stability of the feeding. The second motor 25 drives the rotating rod 24 to drive the cam 27 to rotate. The cam 27 squeezes the screen 26, causing the screen 26 to vibrate up and down with the cooperation of the third spring 28. The process can screen the rice entering the screening box 5, separating impurities or broken rice to ensure the purity of the input. At the same time, vibration can speed up the feeding speed of rice, avoid clogging of the screen 26, improve screening efficiency, and provide high-quality raw materials for subsequent processing. The structure of the vertical rod 29 provides guidance for the sliding of the screen 26, ensuring that the screen 26 remains stable during vibration and avoiding poor screening effect or structural damage due to shaking. At the same time, the vertical rod 29, in conjunction with the third spring 28, can further enhance the stability and regularity of the vibration of the screen 26.
