Description

Technical Field

[0001] This utility model relates to the technical field of unloading mechanisms, specifically an automatic unloading mechanism for a rice transfer buffer silo. Background Technology

[0002] A buffer silo is a container with a certain capacity used to temporarily store rice, serving as a transit point. It is generally cylindrical or square in shape, with a bottom designed to slope towards the discharge port, allowing the rice to gather at the discharge point by its own weight. It is usually made of metal (such as stainless steel to ensure hygiene and durability). During the unloading process of the buffer silo, a discharge structure is usually required. Traditional discharge structures include belt conveyors and screw conveyors.

[0003] During operation, the rice grains fall downwards under their own weight through the grinding inside the buffer bin. Then, the rotating screw conveyor pushes the rice along the conveying pipe to achieve unloading. However, during the unloading process, as the outlet of the buffer bin narrows, the rice gathers towards the outlet under gravity. As the space gradually shrinks, the compression between the rice grains intensifies, and the pressure between them gradually increases. Under this tight compression, the friction between the rice grains and between the rice grains and the inner wall of the outlet also increases accordingly. When the friction becomes large enough to prevent the rice grains from falling smoothly under their own weight, locking and jamming can easily occur, which may eventually lead to blockage and affect unloading efficiency. Therefore, it is necessary to design a highly practical and anti-blocking automatic unloading mechanism for rice transfer buffer bins. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution: an automatic unloading mechanism for a rice transfer buffer bin, comprising a base 1, a plurality of support plates 2 fixedly connected to the upper side of the base 1, a buffer bin body 3 fixedly connected to the upper end of the plurality of support plates 2, a connecting frame 4 fixedly connected to the discharge end of the buffer bin body 3, a conveying frame 5 fixedly connected to the lower end of the connecting frame 4, a rotating rod 6 provided on the inner wall of the conveying frame 5, a conveying thread 7 fixedly connected to the rotating rod 6, and a stepper motor 8 fixedly connected to one end of the conveying frame 5 and fixedly connected to the rotating rod 6;

[0023] The inner wall of the conveying frame 5 is provided with a linkage cavity 9. The drive sprocket 10 located on the inner wall of the linkage cavity 9 is fixedly connected to the rotating rod 6. The upper side of the conveying frame 5 is fixedly connected with a vertical plate 11. A driven sprocket 12 is rotatably engaged on one side of the vertical plate 11. A chain 26 is provided on the driven sprocket 12 and the drive sprocket 10. A hollow block 13 is provided on one side of the inner wall of the connecting frame 4. A stirring rod 14 extending to the inner wall of the buffer chamber 3 is rotatably engaged on the lower side of the inner wall of the hollow block 13. A toggle plate 15 is provided on the stirring rod 14. A linkage mechanism 16 is provided between the stirring rod 14 and the driven sprocket 12.

[0024] Please see Figure 5 The linkage mechanism 16 includes a first bevel gear 161 fixedly connected to the stirring rod 14, a linkage rod 162 fixedly connected to one side of the driven sprocket 12, and a second bevel gear 163 fixedly connected to one end of the linkage rod 162 and meshing with the first bevel gear 161. One end of the linkage rod 162 extends to the inner wall of the hollow block 13 and is rotatably engaged. When the driven sprocket 12 rotates, it drives the linkage rod 162 and the second bevel gear 163 to rotate synchronously. Through the meshing transmission between the second bevel gear 163 and the first bevel gear 161, the power is transmitted to the stirring rod 14, so that the stirring rod 14 can rotate under the support of the hollow block 13.

[0025] Please see Figure 2 The lower side of the conveying frame 5 is provided with a discharge port 17, and a guide frame 18 is fixedly connected to the inner wall of the discharge port 17. The discharge port 17 on the lower side of the conveying frame 5 is used to discharge materials, and the guide frame 18 fixedly connected to its inner wall plays the role of guiding the flow of materials.

[0026] Please see Figure 2 Multiple force-bearing blocks 19 are fixedly connected to one side of the inner wall of the buffer chamber 3. The multiple force-bearing blocks 19 cooperate with the actuating plate 15. The multiple force-bearing blocks 19 on the inner wall of the buffer chamber 3 cooperate with the rotating actuating plate 15. As the actuating plate 15 passes through the gap of the force-bearing blocks 19, it stirs and squeezes the rice in the chamber, which can break the material accumulation state and break up larger lumps, ensuring smooth material flow.

[0027] Please see Figure 5 The inner wall of the hollow block 13 is fixedly connected with a limiting block 21. A limiting port 22 that cooperates with the linkage rod 162 is opened on one side of the limiting block 21. The rotation trajectory of the linkage rod 162 is constrained by the limiting port 22 to ensure that the linkage rod 162 rotates stably in the hollow block 13, thereby ensuring the reliability and accuracy of the power transmission of the entire linkage mechanism 16.

[0028] Please see Figure 1An observation port 23 is provided on one side of the buffer chamber 3. A transparent plate 24 is fixedly connected to the inner wall of the observation port 23. With the help of the transparency of the transparent plate 24, the operator can see the storage and flow of rice inside the buffer chamber 3 through the observation port 23, so as to grasp the relevant status of unloading and perform corresponding operations in a timely manner.

[0029] Please see Figure 2 and Figure 3 A protective block 25 is fixedly connected to the upper side of the conveying frame 5. The protective block 25 is located outside the driven sprocket 12. The protective block 25 forms a shield to protect the driven sprocket 12, preventing external objects from colliding with the driven sprocket 12 and preventing accidental contact by personnel, thereby ensuring the stable and safe operation of the driven sprocket 12 and maintaining the normal operation of the entire unloading mechanism.

[0030] The implementation principle of this application is as follows: First, rice is poured into the interior of the buffer chamber 3 for temporary transfer and storage. When unloading is required, the rice inside moves towards the discharge port of the buffer chamber 3 by gravity. It enters the interior of the conveying frame 5 through the connecting frame 4. The stepper motor 8 is started to drive the rotating rod 6 to rotate. The conveying thread 7 can push the rice to move and be discharged to the guide frame 18 inside the discharge port 17.

[0031] When the rotating rod 6 rotates, the driving sprocket 10 located in the linkage cavity 9 rotates synchronously, driving the driven sprocket 12 on the vertical plate 11 to rotate through the chain 26. The driven sprocket 12 drives the second bevel gear 163 to rotate through the linkage rod 162. The first bevel gear 161 meshing with the second bevel gear 163 rotates accordingly, thereby driving the stirring rod 14 to rotate in the buffer chamber 3. The agitator plate 15 on the stirring rod 14 stirs the rice in the chamber, which can effectively break the squeezed and locked state of the rice at the discharge port of the buffer chamber 3, reduce blockage from the source, and ensure continuous unloading.

[0032] During the rotation process, the actuating plate 15 passes through multiple corresponding force blocks 19, thereby breaking up larger clumps of rice and further improving the smoothness of discharge.
