Description

Technical Field

[0001] This utility model relates to the field of grain conveying technology, and in particular to a discharge port structure for a grain conveying pipeline. Background Technology

[0002] The unloading port structure of a grain conveying pipeline is mainly used to unload grain from the pipeline system during the grain conveying process, ensuring a smooth and unobstructed unloading process and reducing grain loss. Its design and structure should be adjusted according to the type of grain, flow requirements, and the overall design of the conveying system.

[0003] In traditional technology, the unloading port structure of grain conveying pipelines consists of a unloading pipe, an unloading port valve, and a conical structure at the bottom of the unloading port. The design of the unloading port should ensure that the unloading speed of the grain can be adjusted according to demand, to avoid grain overflow or leakage, and to prevent blockage of the unloading port.

[0004] In the existing technology, the discharge port structure of grain conveying pipeline is prone to blockage when handling grains with large or irregular shapes. Blockage of the discharge port will reduce the discharge efficiency and, in severe cases, damage the entire discharge mechanism, reducing the practicality of the device. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a discharge port structure for a grain conveying pipeline, aiming to improve the problem of low discharge efficiency and low practicality of the existing grain conveying pipeline discharge port structure due to easy blockage of the discharge port.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a discharge port structure for a grain conveying pipeline, comprising a base, a mounting frame fixedly connected to the top of the base, a discharger slidably connected inside the mounting frame, a hopper fixedly connected to the top of the discharger, a vibration mechanism provided inside the mounting frame, the vibration mechanism being used to cause the discharger to vibrate during the discharge process to accelerate the discharge speed, and a dust collection mechanism provided at the top of the hopper, the dust collection mechanism being used to absorb and treat the dust generated during the discharge process;

[0007] The vibration mechanism includes four support frames, the tops of which are fixedly connected to the bottom of the unloader, and the bottoms of which are fixedly connected to vibration springs. The bottoms of which are fixedly connected to the interior of the mounting frame.

[0008] As a further description of the above technical solution:

[0009] The bottom of the unloader is fixedly connected to two stabilizing frames, both of which are slidably connected inside the mounting frame.

[0010] As a further description of the above technical solution:

[0011] The unloader is externally fixedly connected to four limiting sleeves, all of which are slidably connected to the outside of the mounting frame.

[0012] As a further description of the above technical solution:

[0013] The dust collection mechanism includes a dust collection box, the bottom of which is fixedly connected to the top of the base. Several mounting shells are fixedly connected inside the dust collection box. Four support blocks are fixedly connected to the top of the unloader. A dust collection ring is fixedly connected to the top of the support blocks. An air pump is fixedly connected to the top of the base. A connecting pipe is fixedly connected to the output end of the air pump.

[0014] As a further description of the above technical solution:

[0015] The input end of the air pump is fixedly connected to the outside of the dust collection box, and the end of the connecting pipe away from the air pump is fixedly connected to the outside of the dust collection ring.

[0016] As a further description of the above technical solution:

[0017] A compression spring is fixedly connected inside the mounting shell, a limit block is fixedly connected to the top of the compression spring, an activated carbon core is provided on the top of the limit block, and a cover is threadedly connected to the top of the mounting shell.

[0018] As a further description of the above technical solution:

[0019] The limiting block is slidably connected inside the mounting shell, and the activated carbon core penetrates through the top of the mounting shell.

[0020] As a further description of the above technical solution:

[0021] The mounting shell has several small holes on its exterior.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the outlet of the grain conveying pipeline is set above the unloader. The grain falls freely into the unloader through the hopper. The impact force generated when the grain falls causes the unloader to move downwards, compressing the vibration spring through the support frame. The vibration spring rebounds and pushes back the support frame, causing the entire unloader to vibrate and accelerate the unloading speed. The limiting sleeves around the unloader can prevent the unloader from falling off the mounting frame. This achieves the effect of the entire unloader vibrating during the unloading process through the vibration mechanism, accelerating the fall of the grain, avoiding blockage of the unloader, improving unloading efficiency, and enhancing the practicality of the device.

[0024] 2. In this utility model, a large amount of dust is generated during the grain unloading process. The air pump is started and the dust is sucked into the dust collection box through the dust collection ring via the connecting pipe. After entering the dust collection box, the dust enters the interior of the mounting shell through small holes and is adsorbed and purified by the activated carbon core. When the activated carbon core is replaced periodically, the cover is opened, and the limit block is pushed upward by the spring force to push the activated carbon core out of the mounting shell for replacement. This achieves the effect of adsorbing and purifying the dust generated by the grain during the unloading process through the dust collection mechanism, purifying the working environment, ensuring the health of the workers, and improving the practicality of the device.

[0032] 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.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a grain conveying pipeline unloading port structure, including a base 1, which supports the upper structure. A mounting frame 2 is fixedly connected to the top of the base 1, which connects to the unloader 3. The unloader 3 is slidably connected inside the mounting frame 2, which connects to the hopper 4. The hopper 4 is fixedly connected to the top of the unloader 3, which unloads material. A vibration mechanism is provided inside the mounting frame 2, which causes the unloader 3 to vibrate during the unloading process to accelerate the unloading speed. A dust collection mechanism is provided on the top of the hopper 4, which absorbs and treats the dust generated during the unloading process.

[0034] The vibration mechanism includes four support frames 5, which connect to the unloader 3. The tops of the four support frames 5 are fixedly connected to the bottom of the unloader 3, and the bottoms of the four support frames 5 are fixedly connected to vibration springs 7, which provide elastic vibration to the unloader 3. The bottoms of the four vibration springs 7 are fixedly connected inside the mounting frame 2. The bottom of the unloader 3 is fixedly connected to two stabilizing frames 6, which connect to the unloader 3. The two stabilizing frames 6 are slidably connected inside the mounting frame 2. The outside of the unloader 3 is fixedly connected to four limiting sleeves 8, which prevent the unloader 3 from falling off. The four limiting sleeves 8 are slidably connected outside the mounting frame 2.

[0035] Specifically, during the unloading process, the grain falls freely into the unloader 3 through the conveying pipe. As the grain falls, it continuously impacts the unloader 3, causing the unloader 3 to continuously impact the vibration spring 7 through the support frame 5. The vibration spring 7 vibrates under force, causing the entire unloader 3 to vibrate, thereby increasing the unloading speed of the grain and preventing blockage inside the unloader 3.

[0036] Reference Figure 1 and Figure 3 - Figure 4The vacuuming mechanism includes a vacuum box 11, the bottom of which is fixedly connected to the top of the base 1. Several mounting shells 14 are fixedly connected inside the vacuum box 11. Four support blocks 9 are fixedly connected to the top of the unloader 3. A vacuum ring 10 is fixedly connected to the top of each support block 9. An air pump 12 is fixedly connected to the top of the base 1. A connecting pipe 13 is fixedly connected to the output end of the air pump 12. The input end of the air pump 12 is fixedly connected to the outside of the vacuum box 11. The end of the connecting pipe 13 away from the air pump 12 is fixedly connected to the outside of the vacuum ring 10. A compression spring 15 is fixedly connected inside the mounting shell 14. A limiting block 16 is fixedly connected to the top of the compression spring 15. An activated carbon core 17 is provided on the top of the limiting block 16. A cover 18 is threadedly connected to the top of the mounting shell 14. The limiting block 16 is slidably connected inside the mounting shell 14. The activated carbon core 17 penetrates the top of the mounting shell 14. Several small holes 19 are opened on the outside of the mounting shell 14.

[0037] The dust generated during the specific grain unloading process is sucked into the dust collection box 11 by the air pump 12 and then freely dispersed inside the dust collection box 11. The dust can be adsorbed by the activated carbon core 17 when it comes into contact with the small hole 19. The activated carbon core 17 can be replaced or its surface dust can be removed regularly.

[0038] Working principle: The outlet of the grain conveying pipeline is set above the unloader 3. The grain falls freely into the unloader 3 through the hopper 4. The impact force generated when the grain falls will cause the unloader 3 to move downward and compress the vibration spring 7 through the support frame 5. The vibration spring 7 rebounds and pushes back the support frame 5, causing the entire unloader 3 to vibrate and accelerate the unloading speed. The limiting sleeves 8 around the unloader 3 can prevent the unloader 3 from falling off the mounting frame 2.

[0039] A large amount of dust is generated during the grain unloading process. The air pump 12 is started and the dust is sucked into the dust collection box 11 through the dust collection ring 10 via the connecting pipe 13. After entering the dust collection box 11, the dust enters the mounting shell 14 through the small hole 19 and is adsorbed and purified by the activated carbon core 17. When the activated carbon core 17 is replaced regularly, the cover 18 is opened and the limit block 16 is pushed upward by the rebound force of the compression spring 15 to push the activated carbon core 17 out of the mounting shell 14 for replacement.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
