Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, specifically relating to a stone transfer station rock dropping funnel. Background Technology

[0002] In the stone processing and transshipment sector, efficient stone transportation and handling have always been key factors for industry development. With the increasing demand for stone from industries such as construction and decoration, the role of stone transshipment stations is becoming increasingly important. An efficient and stable stone transshipment system can significantly improve stone processing efficiency, reduce transportation costs, and play a positive role in promoting the development of the entire stone industry chain. At the same time, the safety and stability of stone during transshipment are also of great concern, as they not only relate to the quality of the stone itself but also involve the safety of operators and the protection of the surrounding environment.

[0003] In traditional stone transfer stations, simple structures are typically used to handle falling stones during the unloading process. On one hand, ordinary fixed funnels are used to catch the falling stones; these funnels are directly mounted on the outer shell, resulting in a relatively simple structure and low manufacturing cost. On the other hand, simple elastic components, such as simple rubber pads, are sometimes placed between the funnel and the outer shell to try and provide some cushioning against potential vibrations and impacts. However, these methods are often independent and lack systematicity and coordination.

[0004] Existing methods for handling falling stones at stone transfer stations have significant flaws. Ordinary fixed hoppers, lacking effective cushioning structures, cannot adequately handle the impact of falling stones, easily leading to damage to the hopper and its outer casing, thus shortening the equipment's lifespan. Furthermore, when stones become stuck in the hopper, there is no suitable detachment mechanism, requiring manual intervention, which is not only inefficient but also increases the workload and safety risks for operators. Utility Model Content

[0005] The purpose of this utility model is to provide a stone transfer station rock-falling funnel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stone transfer station rock-falling funnel, comprising an outer shell, a movable funnel extending through the outer shell, a buffer mechanism connected between the outer shell and the funnel, the buffer mechanism comprising a bottom plate, a bottom plate provided at the inner bottom of the outer shell, a second spring installed between the bottom plate and the outer shell, a rotating rod installed at the bottom of the funnel, the rotating rod being rotatably connected to the bottom plate, and a third spring installed between the side wall of the funnel and the inner wall of the outer shell;

[0007] The funnel is connected to a release mechanism, which includes a top block. Multiple top blocks are slidably connected to the inner wall of the funnel. A fixing strip is installed on the funnel, and a piston rod is slidably connected to the fixing strip. One end of the piston rod is fixed to the top block. An air bladder is installed between the outer shell and the funnel. A connecting pipe is installed between the air bladder and the fixing strip. The air bladder is connected to the cavity where the piston rod is located through the connecting pipe.

[0008] In a preferred embodiment, both the outer shell and the sidewalls of the funnel are equipped with contact plates, and the airbag is installed between a pair of contact plates.

[0009] In a preferred embodiment, the fixing bar has a first spring inside, and the two ends of the first spring are fixed to the fixing bar and the piston rod, respectively.

[0010] In a preferred embodiment, the bottom end of the funnel is rectangular and the funnel penetrates the bottom plate.

[0011] In a preferred embodiment, multiple second springs are provided, and the multiple second springs are respectively provided on the corners of the base plate.

[0012] In a preferred embodiment, dust discharge grooves are provided on both sides of the bottom of the outer casing, and the dust discharge grooves are through grooves.

[0013] In a preferred embodiment, the top of the funnel is rectangular and covers the top of the outer shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention involves installing a funnel at the end of a stone conveyor belt. When conveying stone, some large coal chunks impact the inner wall of the funnel, causing it to deflect under the action of a rotating rod. The third spring on one side is compressed, thus cushioning the coal chunks and preventing damage to the funnel. Dust entering the outer shell can be discharged through the dust discharge trough. When a large amount of material is discharged, the weight of the coal chunks inside the funnel will cause it to move downwards, pushing the bottom plate downwards. The second spring is compressed, and after the coal chunks are discharged, the second spring pushes the funnel back to its original position. During the up-and-down movement of the funnel, external air can be promoted to enter the outer shell through the dust discharge trough and then be discharged, increasing airflow and thus preventing dust accumulation.

[0016] In this invention, when the funnel moves downward, the air bladder is squeezed by the contact plate, thereby creating pressure at one end of the piston rod through the connecting pipe. This pushes the piston rod and the top block to extend, causing the surface of the top block to misalign with the inner wall of the funnel. This pushes the adhered coal slag, making it easier for the coal slag to detach and reducing adhesion. Similarly, when the funnel moves upward, the top block returns to its original position.

[0024] Please see Figures 1-4 This utility model provides a stone transfer station rock dropping funnel, including an outer shell 1, a movable funnel 2 passing through the outer shell 1, a buffer mechanism 5 connected between the outer shell 1 and the funnel 2, the buffer mechanism 5 including a bottom plate 53, the bottom of the inner end of the outer shell 1 is provided with a bottom plate 53, a second spring 51 is installed between the bottom plate 53 and the outer shell 1, a rotating rod 54 is installed at the bottom end of the funnel 2, the rotating rod 54 is rotatably connected to the bottom plate 53, and a third spring 52 is installed between the side wall of the funnel 2 and the inner wall of the outer shell 1, thereby facilitating the buffering of the funnel 2;

[0025] A detachment mechanism 3 is connected to the funnel 2. The detachment mechanism 3 includes a top block 31. Multiple top blocks 31 are slidably connected to the inner wall of the funnel 2. A fixing strip 34 is installed on the funnel 2. A piston rod 36 is slidably connected to the fixing strip 34. One end of the piston rod 36 is fixed to the top block 31. An air bladder 32 is installed between the outer shell 1 and the funnel 2. A connecting pipe 35 is installed between the air bladder 32 and the fixing strip 34. The air bladder 32 is connected to the cavity where the piston rod 36 is located through the connecting pipe 35, thereby facilitating the detachment of the adhered coal slag.

[0026] Specifically, such as Figure 2As shown, both the outer shell 1 and the funnel 2 are equipped with abutment plates 33, and the airbag 32 is installed between a pair of abutment plates 33, which facilitates the compression of the airbag 32.

[0027] Specifically, such as Figure 4 As shown, a first spring 37 is provided inside the fixing bar 34. The two ends of the first spring 37 are fixed to the fixing bar 34 and the piston rod 36 respectively, so as to facilitate the piston rod 36 to return to its original position.

[0028] Specifically, such as Figure 3 As shown, the bottom of the funnel 2 is rectangular, and the funnel 2 passes through the bottom plate 53, which facilitates the deflection of the funnel 2.

[0029] Specifically, such as Figure 2 As shown, multiple second springs 51 are provided, and the multiple second springs 51 are respectively provided on the corners of the base plate 53, so as to ensure that the funnel 2 can be reset after deflection.

[0030] Specifically, such as Figure 1 As shown, dust discharge grooves 4 are provided on both sides of the bottom of the outer casing 1. The dust discharge grooves 4 are through grooves, which facilitate the discharge of dust that enters the interior of the outer casing 1.

[0031] Specifically, such as Figure 2 As shown, the top of the funnel 2 is rectangular, and the top of the funnel 2 covers the top of the outer shell 1.

[0032] The working principle and usage process of this utility model are as follows: The funnel 2 is installed at the end of the stone conveyor belt. When conveying stone, some coal blocks are large and impact the inner wall of the funnel 2. Under the action of the rotating rod 54, the funnel 2 deflects, and the third spring 52 on one side is compressed, thereby cushioning the coal blocks and preventing damage to the funnel 2. Dust that has entered the outer shell 1 can be discharged from the dust discharge trough 4. When there is a large amount of material being discharged, the weight of the coal blocks inside the funnel 2 will cause it to move downward, thereby pushing the bottom plate 53 downward. The second spring 51 is compressed, and after the coal blocks are discharged, the second spring 51 pushes the funnel 2 to return to its original position. During the up-and-down movement of the funnel 2, external air can enter the interior of the outer shell 1 through the dust discharge groove 4 and be discharged, thereby increasing airflow and preventing dust accumulation. When the funnel 2 moves downward, it can squeeze the air bag 32 through the contact plate 33, thereby forming pressure at one end of the piston rod 36 through the connecting pipe 35, thereby pushing the piston rod 36 and the top block 31 to extend, causing the surface of the top block 31 to be misaligned with the inner wall of the funnel 2, thereby pushing the adhered coal slag, thus facilitating the detachment of the coal slag and reducing adhesion. Similarly, when the funnel 2 moves upward, the top block 31 returns to its original position.
