Technical Field
[0001] This utility model relates to the field of curved chute technology, specifically a buffer mechanism for curved chute. Background Technology
[0002] Curved chutes are a new type of chute design that optimizes material conveying paths to reduce impact, wear, and dust. They are widely used in industries such as mining, coal, metallurgy, and food processing. Their core principle is to guide materials to slide along a predetermined trajectory through curvature design, transforming the "free fall" of traditional straight chutes into "controlled flow," thereby achieving efficient and low-consumption conveying. Curved chutes mainly consist of a feeding section, a curved buffer section, and a discharge section. The feeding section is the material inlet area, the curved buffer section is the core turning area, and the discharge section is the material outlet area.
[0003] In the existing technology, the material enters the curved buffer section through the feeding section of the curved chute. The curved surface constraint makes the material flow along the preset trajectory, reducing the impact and splashing during the turning process. The constrained material is discharged through the discharge section.
[0004] In practical use, to ensure that materials can pass smoothly through the curved buffer section and the discharge section of the curved chute, the discharge section is usually set in a vertical state to avoid material blockage at the connection between the curved buffer section and the discharge section. However, when the material flows from the curved buffer section to the discharge section, the impact on the inner wall is due to the interaction between the sudden change in the material's motion state and the constraint of the inner wall. The impact of the material on the inner wall of the discharge section will aggravate the wear of the inner wall and cause vibration, resulting in excessive local stress in the discharge section and deformation at the impact point. Therefore, a buffer mechanism for curved chute is proposed to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a buffer mechanism for curved chutes, which has the advantage of buffering the material flowing into the discharge section. It solves the problem of the impact on the inner wall when the material flows from the curved buffer section to the discharge section. The sudden change in the material's motion state interacts with the constraint of the inner wall. The impact of the material on the inner wall of the discharge section will aggravate the wear of the inner wall and cause vibration, resulting in excessive local stress in the discharge section and deformation at the impact point.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a buffer mechanism for a curved chute, comprising a curved buffer section and a material discharge section disposed on the curved chute, wherein the material discharge section is provided with a buffer mechanism for reducing material impact.
[0007] The buffer mechanism includes a flow guiding component disposed inside the material dropping section for guiding the material. The flow guiding component is provided with a connecting component. The material dropping section is provided with an adjusting component connected to the flow guiding component. A cylinder is fixedly installed on the material dropping section, and the telescopic end of the cylinder is connected to the adjusting component.
[0008] The flow guiding component includes a flow guiding plate, a mounting rod is fixedly connected to the top of the flow guiding plate, a through groove adapted to the mounting rod is opened on the material dropping section, and the mounting rod is slidably connected to the through groove. A guide frame is fixedly installed on the flow guiding plate.
[0009] The connecting component includes a connecting plate, which is slidably mounted inside the guide frame. Two symmetrically distributed connecting columns are hinged to the connecting plate.
[0010] The adjusting component includes an adjusting frame that is slidably installed on the material dropping section, and the telescopic end of the cylinder is fixedly connected to the adjusting frame. Two connecting sleeves are fixedly installed inside the adjusting frame, and the end of the connecting column passes through the connecting sleeve. The connecting column and the connecting sleeve are slidably connected.
[0011] Furthermore, a spring is fixedly installed at one end of each of the two connecting sleeves, and the spring is sleeved on the corresponding connecting post. A washer is fixedly installed at the end of each of the two connecting posts, and the washer is fixedly connected to the end of the spring.
[0012] Furthermore, an anti-slip plate is fixedly installed on the guide frame to prevent the connecting plate from slipping off, and one side of the anti-slip plate is slidably connected to the connecting plate, with the connecting plate located on the central axis of the guide frame.
[0013] Furthermore, a rectangular groove is provided on the material dropping section, and the adjustment frame is slidably installed in the rectangular groove. Two reinforcing plates for supporting the connection of the cylinder extension and retraction ends are fixedly installed on the adjustment frame.
[0014] Furthermore, an inclined boss is fixedly installed on the inner wall of the material dropping section. The inclined boss is located directly above the top of the guide plate, and the inclined surface of the inclined boss is 60 degrees.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] 1. The buffer mechanism for curved chute is driven by a cylinder to move the adjusting component, which in turn drives the guide plate to move through the connecting component. This achieves a combined motion of controlling the sliding and rotation of the guide plate, thereby actively adjusting the angle of the guide plate, guiding the material, dispersing the impact of the material, adapting to the material flow direction under different impact intensities, and preventing the material from directly impacting the inner wall of the drop section.
[0017] 2. The buffer mechanism used in the curved chute compresses the spring by sliding the connecting column along the connecting sleeve when the material impacts the guide plate. The elastic potential energy of the spring absorbs the impact energy. After the impact weakens, the spring resets and drives the connecting column back to its original position, which transforms the rigid impact of the material on the guide plate into a flexible buffer of elastic deformation and reset, reducing the reaction force of the impact on the adjustment components and reducing mechanical fatigue.
[0018] 3. The buffer mechanism used in the curved chute pre-guides part of the material after it flows out of the curved buffer section, changing the direction of movement of part of the material so that it impacts the guide plate at a gentler angle, reducing the impact force directly acting on the guide plate and reducing the load and wear of the guide plate.

[0026] 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.
[0027] Example 1: Please refer to Figure 1-5 A buffer mechanism for a curved chute in this embodiment includes a curved buffer section 1 and a discharge section 2 disposed on the curved chute. The discharge section 2 is provided with a buffer mechanism 3 for reducing material impact.
[0028] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, the buffer mechanism 3 includes a flow guiding component 31 disposed inside the material dropping section 2 and used to guide the material. A connecting component 32 is disposed on the flow guiding component 31. An adjusting component 33 connected to the flow guiding component 31 is disposed on the material dropping section 2. A cylinder 34 is fixedly installed on the material dropping section 2, and the telescopic end of the cylinder 34 is connected to the adjusting component 33.
[0029] The flow guiding component 31 includes a flow guiding plate 311, a mounting rod 312 is fixedly connected to the top of the flow guiding plate 311, a through groove 23 adapted to the mounting rod 312 is opened on the material dropping section 2, and the mounting rod 312 is slidably connected to the through groove 23. A guide frame 313 is fixedly installed on the flow guiding plate 311.
[0030] The connecting component 32 includes a connecting plate 321, which is slidably mounted inside the guide frame 313. Two symmetrically distributed connecting posts 322 are hinged on the connecting plate 321.
[0031] The adjusting component 33 includes an adjusting frame 331 that is slidably installed on the material dropping section 2, and the telescopic end of the cylinder 34 is fixedly connected to the adjusting frame 331. Two connecting sleeves 332 are fixedly installed inside the adjusting frame 331, and the end of the connecting column 322 passes through the connecting sleeve 332. The connecting column 322 is slidably connected to the connecting sleeve 332.
[0032] The guide frame 313 is fixedly equipped with an anti-slip plate 314 to prevent the connecting plate 321 from slipping. One side of the anti-slip plate 314 is slidably connected to the connecting plate 321. The connecting plate 321 is located on the central axis of the guide frame 313. When the connecting plate 321 slides in the guide frame 313, the anti-slip plate 314 prevents it from slipping by limiting it from the side. The central arrangement ensures that the connecting plate 321 is evenly stressed and avoids unilateral deviation.
[0033] In addition, a rectangular groove 21 is provided on the material dropping section 2, and the adjustment frame 331 is slidably installed in the rectangular groove 21. Two reinforcing plates are fixedly installed on the adjustment frame 331 to support the connection of the telescopic end of the cylinder 34. The reinforcing plates improve the shear strength of the connection between the cylinder 34 and the adjustment frame 331. Especially under large impact loads, they can prevent the connection from breaking and reduce the equipment failure rate.
[0034] It should be noted that a sloping boss 22 is fixedly installed on the inner wall of the material discharge section 2. The sloping boss 22 is located directly above the top of the guide plate 311, and the sloping surface of the sloping boss 22 is 60 degrees. After the material flows out from the curved buffer section 1, it is first pre-guided by the sloping boss 22, which changes the direction of movement of some materials, so that they impact the guide plate 311 at a gentler angle, reducing the impact force directly acting on the guide plate 311 and reducing the load and wear of the guide plate 311.
[0035] Using the above technical solution, the cylinder 34 starts, and its telescopic end pushes the adjusting frame 331 to slide along the rectangular groove 21 of the material dropping section 2. The adjusting frame 331 drives the connecting plate 321 to slide in the guide frame 313 through the connecting sleeve 332 and the connecting column 322, thereby driving the guide plate 311 to achieve a combined sliding and rotating motion in the through groove 23 through the mounting rod 312, thereby adjusting the guide plate 311 to the optimal guiding angle. After the material flows out from the curved buffer section 1, some of the material contacts the inclined boss 22 in the inner cavity of the material dropping section 2. The inclined boss 22 pre-guides the material in the direction of the guide plate 311, changing the initial movement trajectory of some of the material and reducing the energy of direct impact on the guide plate 311.
[0036] Example 3: Please refer to Figure 1-5 Based on Embodiment 2, springs 333 are fixedly installed at one end of each of the two connecting sleeves 332, and springs 333 are sleeved on the corresponding connecting posts 322. Gaskets 334 are fixedly installed at the ends of the two connecting posts 322, and gaskets 334 are fixedly connected to the ends of springs 333. When material impacts the guide plate 311, the connecting posts 322 slide along the connecting sleeves to compress the springs 333, and the elastic potential energy of the springs 333 absorbs the impact energy. After the impact weakens, the springs 333 reset and drive the connecting posts 322 back to their original positions to ensure the stability of the guide plate 311.
[0037] By adopting the above technical solution, an elastic buffer is introduced to transform the rigid impact of the material on the guide plate 311 into a flexible buffer of "elastic deformation and reset", thereby reducing the reaction force of the impact on the regulating component 33 and reducing mechanical fatigue.
[0038] The working principle of the above embodiments is as follows:
[0039] In use, the buffer mechanism for the curved chute allows material to flow out of the curved buffer section 1, and some of the material contacts the inclined boss 22 in the inner cavity of the drop section 2. The inclined boss 22 pre-guides the material in the direction of the guide plate 311, changing the initial trajectory of some of the material and reducing the energy of direct impact on the guide plate 311.
[0040] When material impacts the guide plate 311, the guide plate 311 slides and rotates in the through groove 23 of the material drop section 2 via the mounting rod 312 at the top. It can rotate around the axis of the mounting rod 312 to adjust the angle, and can also slide slightly along the through groove 23 to buffer and guide the material to flow in the preset direction. The impact force on the guide plate 311 is transmitted to the connecting plate 321 through the guide frame 313. The connecting plate 321 pushes the connecting columns 322 on both sides to slide along the connecting sleeve 332 in the adjusting frame 331, compressing the spring 333. The elastic deformation of the spring 333 absorbs the impact energy. The gasket 334 prevents the connecting column 322 from directly rubbing against the spring 333, thus protecting the components.
[0041] When the material flow rate, particle size, or impact intensity changes, the cylinder 34 is activated, and its telescopic end pushes the adjusting frame 331 to slide along the rectangular groove 21 of the material drop section 2. The adjusting frame 331 drives the connecting plate 321 to slide in the guide frame 313 through the connecting sleeve 332 and the connecting column 322, thereby driving the guide plate 311 to achieve a combined sliding and rotating motion in the through groove 23 through the mounting rod 312, thereby adjusting the guide plate 311 to the optimal guiding angle.
