Description

Technical Field

[0001] This utility model relates to the technical field of coal conveying equipment, specifically a coal chute buffer device. Background Technology

[0002] In the coal mining, processing, and transportation process, coal chutes are key equipment for vertical or inclined coal transfer, and their operational stability directly affects coal transportation efficiency and equipment lifespan. However, existing coal chutes have the following prominent problems in practical applications:

[0003] When coal falls from a height into a coal chute, its own weight and falling speed generate a significant impact force, which directly acts on the inner wall and bottom structure of the coal chute. Long-term impact causes wear, deformation, and even cracks in the inner wall of the coal chute, requiring frequent repairs and replacements, increasing equipment maintenance costs, and affecting the continuity of coal transportation.

[0004] Coal particles are uneven in size, and some wet coal is prone to caking, which can easily accumulate at the bottom or corners of the chute during the coal conveying process. If the accumulated material is not cleaned up in time, it will gradually block the coal conveying channel, causing coal transportation to be interrupted. This requires manual shutdown for cleaning, which not only reduces production efficiency but also increases the labor intensity of operators and may even pose safety hazards.

[0005] Existing coal chutes mostly rely on their own tilt angle to allow material to slide down, without incorporating active disturbance and flow guiding structures. When the material flow rate fluctuates or the particle distribution is uneven, material is prone to concentrating and impacting a certain area, exacerbating local wear and further increasing the risk of accumulation and blockage. In view of this, we propose a coal chute buffer device to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to provide a buffer device for a coal chute to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coal chute buffer device, comprising a fixed frame, a coal chute frame, a drive motor, a guide groove, an installation component, a coal chute, a buffer mechanism, and a movable groove. The installation component is symmetrically arranged on one side of the fixed frame, a coal chute is provided inside the fixed frame, a coal chute frame is movably connected inside the coal chute, and a guide groove is symmetrically provided on the side of the fixed frame near the installation component. The coal chute frame is located on the guide groove, and a buffer mechanism is provided inside the coal chute.

[0008] Preferably, the buffer mechanism includes a buffer seat, a buffer rod, a buffer spring, a cam, a first synchronous pulley, a movable rod, a synchronous belt, a second synchronous pulley, and a baffle. Buffer seats are fixedly connected to the four corners of the coal chute, buffer rods are provided on the buffer seats, and coal chute frames are fixedly connected to the buffer rods. Buffer springs are sleeved on the buffer rods between the coal chute frames and the buffer seats. A movable rod is movably connected inside the coal chute, and a cam is provided on the movable rod.

[0009] Preferably, a drive motor is fixedly connected to one side of the fixed frame, a movable rod is fixedly connected to the output end of the drive motor, a first synchronous pulley is provided on one side of the movable rod, a baffle is movably connected to the fixed frame, a second synchronous pulley is fixedly connected to one side of the baffle, and a synchronous belt is sleeved on the first and second synchronous pulleys.

[0010] Preferably, the coal chute is symmetrically provided with movable slots, and the baffle is located on the movable slots. A shim is provided on the cam, and the cam and the coal chute cooperate with each other.

[0011] Preferably, the turbulence-disrupting component includes a turbulence-disrupting shaft and a secondary turbulence-disrupting plate, which cooperates with the coal chute.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When materials such as coal enter from above the coal chute, they first fall onto the coal chute frame. The weight of the material itself and the impact force of falling will exert downward pressure on the coal chute frame. At this time, the coal chute frame will slide down along the guide groove after being subjected to pressure, and at the same time drive the buffer rod to move towards the buffer seat, so that the buffer spring sleeved on the buffer rod is compressed. The elastic deformation of the buffer spring will absorb part of the impact force, realizing the initial buffering of the impact of falling material and reducing the direct impact damage of material to the device.

[0014] 2. After the drive motor starts, its output end drives the movable rod to rotate, and the cam on the movable rod rotates together. Since the cam and the coal chute cooperate with each other, the cam will periodically lift the coal chute during rotation. When the cam's protruding part contacts the coal chute, the coal chute is lifted upward. When the cam's protruding part leaves the coal chute, the coal chute moves downward again under its own weight and material pressure. The buffer spring is compressed again. Through the periodic action of the cam, the coal chute realizes up and down reciprocating motion. On the one hand, it further absorbs the impact energy of the material through the extension and contraction of the buffer spring. On the other hand, it makes the material vibrate on the coal chute to avoid material accumulation and promote the downward sliding of the material.

[0015] 3. When the movable rod rotates, it drives the first synchronous pulley to rotate. The first synchronous pulley drives the second synchronous pulley to rotate via a synchronous belt, which in turn causes the baffle fixedly connected to the second synchronous pulley to rotate. When the baffle shaft of the baffle rotates, the baffle plate on its outer side will rotate synchronously in the movable trough of the coal chute. Since the baffle plate and the coal chute cooperate with each other, the rotating baffle plate will disturb the material on the coal chute, disrupt the downward trajectory of the material, make the material fall more dispersed, avoid the material from concentrating and impacting a certain part, and further reduce the impact of the material on the device. In addition, the baffle effect can also prevent the material from clogging on the coal chute and ensure the smooth operation of the coal chute process. Attached Figure Description

[0021] 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 specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] like Figures 1-4 As shown, the present invention proposes a coal chute buffer device, including a fixed frame 1, a coal chute frame 2, a drive motor 3, a guide groove 4, a mounting component 5, a coal chute 6, a buffer mechanism 7, and a movable groove 8. The mounting component 5 is symmetrically arranged on one side of the fixed frame 1, the coal chute 6 is opened in the fixed frame 1, the coal chute frame 2 is movably connected in the coal chute 6, and the guide groove 4 is symmetrically opened on the side of the fixed frame 1 near the mounting component 5. The coal chute frame 2 is located on the guide groove 4, and the buffer mechanism 7 is arranged in the coal chute 6.

[0023] When materials such as coal enter from above the coal chute 6, they first fall onto the coal chute frame 2. The weight of the material itself and the impact force of falling will exert downward pressure on the coal chute frame 2. At this time, the coal chute frame 2 will slide downward along the guide groove 4 after being subjected to pressure, and at the same time drive the buffer rod 702 to move towards the buffer seat 701, so that the buffer spring 703 sleeved on the buffer rod 702 is compressed. The elastic deformation of the buffer spring 703 will absorb part of the impact force, realizing the initial buffering of the impact of falling material and reducing the direct impact damage of material to the device.

[0024] In an optional embodiment, the buffer mechanism 7 includes a buffer seat 701, a buffer rod 702, a buffer spring 703, a cam 704, a first synchronous pulley 705, a movable rod 706, a synchronous belt 707, a second synchronous pulley 708, and a baffle 709. Buffer seats 701 are fixedly connected to the four corners of the coal chute 6. Buffer rods 702 are provided on each buffer seat 701. Coal chute frames 2 are fixedly connected to each buffer rod 702. A buffer spring 703 is sleeved on the buffer rod 702 between the coal chute frame 2 and the buffer seat 701. A movable rod 706 is movably connected inside the coal chute 6, and a cam 704 is provided on the movable rod 706.

[0025] After the drive motor 3 starts, its output end drives the movable rod 706 to rotate, and the cam 704 on the movable rod 706 rotates together. Since the cam 704 cooperates with the coal chute 2, the cam 704 will periodically lift the coal chute 2 during rotation. When the protruding part of the cam 704 contacts the coal chute 2, the coal chute 2 is lifted upward. When the protruding part of the cam 704 leaves the coal chute 2, the coal chute 2 moves downward again under its own weight and material pressure. The buffer spring 703 is compressed again. Through the periodic action of the cam 704, the coal chute 2 realizes up and down reciprocating motion. On the one hand, the buffer spring 703 absorbs the impact energy of the material through its extension and contraction. On the other hand, it makes the material vibrate on the coal chute 2 to avoid material accumulation and promote the downward sliding of the material.

[0026] In an optional embodiment, a drive motor 3 is fixedly connected to one side of the fixed frame 1, a movable rod 706 is fixedly connected to the output end of the drive motor 3, a first synchronous pulley 705 is provided on one side of the movable rod 706, and a baffle 709 is movably connected to the fixed frame 1. A second synchronous pulley 708 is fixedly connected to one side of the baffle 709, and a synchronous belt 707 is sleeved on the first synchronous pulley 705 and the second synchronous pulley 708.

[0027] When the movable rod 706 rotates, it drives the first synchronous wheel 705 to rotate. The first synchronous wheel 705 drives the second synchronous wheel 708 to rotate through the synchronous belt 707, which in turn causes the baffle 709, which is fixedly connected to the second synchronous wheel 708, to rotate. When the baffle shaft of the baffle 709 rotates, the baffle plate on its outer side will rotate synchronously in the movable trough 8 of the coal chute 2. Since the baffle plate and the coal chute 2 cooperate with each other, the rotating baffle plate will have a disturbing effect on the material on the coal chute 2, disrupting the downward trajectory of the material, making the material fall more dispersed, avoiding the material from concentrating on impacting a certain part, and further reducing the impact of the material on the device. In addition, the baffle effect can also prevent the material from clogging on the coal chute 2 and ensure the smooth operation of the coal chute process.

[0028] In an optional embodiment, the coal chute 2 is symmetrically provided with movable grooves 8, and the baffle 709 is located on the movable grooves 8. A shim is provided on the cam 704, and the cam 704 and the coal chute 2 cooperate with each other.

[0029] In an optional embodiment, the turbulence element 709 includes a turbulence shaft and a secondary turbulence plate, which cooperates with the coal chute.

[0030] The working principle of this utility model is as follows: When using this device, when materials such as coal enter from above the coal chute 6, they first fall onto the coal chute frame 2. The weight of the material itself and the impact force of falling will exert downward pressure on the coal chute frame 2. At this time, after being subjected to pressure, the coal chute frame 2 will slide down along the guide groove 4, and at the same time drive the buffer rod 702 to move towards the buffer seat 701, so that the buffer spring 703 sleeved on the buffer rod 702 is compressed. The elastic deformation of the buffer spring 703 will absorb part of the impact force, realize the initial buffering of the impact of falling material, and reduce the direct impact damage of material to the device.

[0031] After the drive motor 3 starts, its output end drives the movable rod 706 to rotate, and the cam 704 on the movable rod 706 rotates together. Since the cam 704 cooperates with the coal chute 2, the cam 704 will periodically lift the coal chute 2 during rotation. When the protruding part of the cam 704 contacts the coal chute 2, the coal chute 2 is lifted upward. When the protruding part of the cam 704 leaves the coal chute 2, the coal chute 2 moves downward again under its own weight and material pressure. The buffer spring 703 is compressed again. Through the periodic action of the cam 704, the coal chute 2 realizes up and down reciprocating motion. On the one hand, the buffer spring 703 absorbs the impact energy of the material through its extension and contraction. On the other hand, it makes the material vibrate on the coal chute 2 to avoid material accumulation and promote the downward sliding of the material.

[0032] Simultaneously, when the movable rod 706 rotates, it drives the first synchronous wheel 705 to rotate. The first synchronous wheel 705 drives the second synchronous wheel 708 to rotate through the synchronous belt 707, which in turn causes the baffle 709, which is fixedly connected to the second synchronous wheel 708, to rotate. When the baffle shaft of the baffle 709 rotates, the baffle plate on its outer side will rotate synchronously in the movable trough 8 of the coal chute 2. Since the baffle plate and the coal chute 2 cooperate with each other, the rotating baffle plate will have a disturbing effect on the material on the coal chute 2, disrupting the downward trajectory of the material, making the material fall more dispersed, avoiding the material from concentrating on impacting a certain part, and further reducing the impact of the material on the device. In addition, the baffle effect can also prevent the material from clogging on the coal chute 2, ensuring the smooth operation of the coal chute process.
