Description

Technical Field

[0001] This utility model relates to the field of warehousing equipment, and in particular to a warehousing unloading mechanism. Background Technology

[0002] Storage and unloading mechanisms in silos are widely used in actual production processes. However, in practice, problems such as poor or incomplete unloading often occur. To address this issue, most solutions involve adding vibratory hammers to the silo, which cause the powder to fall through the vibrations.

[0003] While this can solve the problems of uneven and incomplete material feeding to some extent, controlling the vibratory hammer remains a challenge for different materials. One approach is to keep the vibratory hammer running continuously during the feeding process, which increases compressed air consumption and may cause some easily compacted materials to become even more compacted, making them even harder to discharge. Another approach is to turn it on only at intervals, which avoids the problem of the material becoming increasingly compacted but ensures uniform material feeding.

[0004] Therefore, how to propose a material unloading mechanism for the silo has become a technical problem that urgently needs to be solved in the industry. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, this utility model provides a bin unloading mechanism that can easily unload materials.

[0006] Technical solution: A bin unloading mechanism, comprising:

[0007] The discharge valve is installed at the discharge port of the silo body, and the discharge valve includes an impeller for regular discharge;

[0008] A support frame disposed within the hopper and located above the discharge valve;

[0009] A guide post is disposed on the support frame and configured to periodically rise / fall as the impeller rotates, the top end of the guide post regularly impacting the support frame during the periodic rise / fall of the guide post.

[0010] Furthermore, a roller is movably connected to the bottom end of the guide post, and the roller is rotatably connected to the blades of the impeller.

[0011] Furthermore, the guide post is arranged to penetrate the support frame, and a cap is provided at the top of the guide post. When the guide post descends, the cap strikes the support frame.

[0012] Furthermore, an adjusting bolt is fitted on the lower part of the guide post, and an elastic element is also fitted on the guide post. The top end of the elastic element abuts against the bottom end of the support frame, and the bottom end of the elastic element abuts against the adjusting bolt.

[0013] Furthermore, the support frame is provided with a plurality of sealing rings around the guide post.

[0014] Furthermore, the support frame is also equipped with a dust cover, which is arranged to cover the cap.

[0015] Beneficial effects: The bin unloading mechanism of this utility model is equipped with guide columns that can be periodically raised / lowered. When the guide columns are periodically raised / lowered, they hit the support frame and vibrate the bin to achieve auxiliary unloading. At the same time, the guide columns and impeller are linked. No additional power device is required. The unloading function can be achieved by the unloading valve alone. The structure is simple, the cost is low, the reliability is high, and it is easy to manufacture and promote. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] It should be noted that the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope of this utility model.

[0021] See Figure 1-3An embodiment of the hopper unloading mechanism of this utility model is shown, comprising: an unloading valve 3, a support frame 25, and a guide column 26. The unloading valve 3 is disposed at the unloading port of the hopper 1 to control the unloading of materials from the hopper 1. The unloading valve 3 includes an impeller 31 for regular unloading. The support frame 25 is disposed inside the hopper 1 and above the unloading valve 3. Specifically, it has a cross-shaped structure, thereby improving the internal volume ratio of the hopper 1 while meeting strength requirements. The guide column 26 is disposed on the support frame 25 and configured to periodically rise / fall with the rotation of the impeller 31. The top end of the guide column 26 periodically impacts the support frame 25 during the periodic rise / fall of the guide column 26.

[0022] By setting a guide column 26 that can periodically rise / fall, and causing the guide column 26 to strike the support frame 25 during periodic rise / fall, thereby vibrating the bin 1, the material is assisted in unloading. At the same time, the guide column 26 and the impeller 31 are linked together. No additional power unit is required. The unloading valve 3 alone can achieve the function of assisted unloading. The structure is simple, the cost is low, the reliability is high, and it is easy to manufacture and promote.

[0023] In some preferred embodiments, a roller 21 is movably connected to the bottom end of the guide post 26, and the roller 21 is rolled onto the blades 32 of the impeller 31. Thus, during the rotation of the impeller 31, when the roller 21 passes the blades 32, the guide post 26 is pressed down by gravity and impacts the support frame 25. The impact causes the support frame 25 to vibrate along with the hopper 1, and the material slides down due to the vibration. As the impeller 31 continues to rotate, the roller 21 presses back onto the blades 32, and the guide post 26 gradually moves upward. This process repeats, and the extension and retraction of the guide post 26 causes the support frame 25 to vibrate, thereby achieving the downward sliding of the material.

[0024] In some preferred embodiments, the guide post 26 is disposed through the support frame 25, and a cap is provided at the top of the guide post 26. When the guide post 26 descends, the cap impacts the support frame 25. An adjusting bolt 22 is fitted on the lower part of the guide post 26, and an elastic element 23, preferably a spring, is also fitted on the guide post 26. The top of the elastic element 23 abuts against the bottom end of the support frame 25, and the bottom end of the elastic element 23 abuts against the adjusting bolt 22. In this way, the expansion and contraction of the elastic element 23 imparts greater potential energy to the guide post 26, resulting in a better impact effect.

[0025] In some preferred embodiments, the support frame 25 is provided with a plurality of sealing rings 24 around the guide post 26 to prevent material from entering the gap between the guide post 26 and the support frame 25. Furthermore, the support frame 25 is also provided with a dust cover 27, which is configured to cover the cap.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
