Each support has a power storage component at its top. The power storage component includes a hydraulic cylinder fixedly connected to the top of the support. A moving block is fixedly connected to the telescopic end of the hydraulic cylinder. A traction column is fixedly connected to one side of the moving block. A right-angled trapezoidal block is abutted against the outer wall of one side of the traction column. A sliding rod is fixedly connected to one side of the right-angled trapezoidal block.

Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically a bidirectional hydraulic coal unloader. Background Technology

[0002] In the fields of coal mining, transportation, and storage, coal in equipment such as coal bunkers and chutes is prone to bridging and blockage due to factors such as moisture content, particle size differences, and stacking pressure. If not cleared in time, this can lead to interruption of the transportation system, overload and damage to equipment, seriously affecting production efficiency and operational safety. To solve this problem, the bidirectional hydraulic coal unloader is widely used as a core unblocking device. Its core function is to apply external force to the blocked coal through a power-driven actuator, breaking the stacking structure to achieve unblocking.

[0003] In existing technologies, traditional bidirectional hydraulic coal unloaders generally use hydraulic cylinders to directly drive unblocking, that is, the linear reciprocating motion of the hydraulic cylinder piston rod directly drives the unblocking components to push and impact the blocked area. However, the hydraulic cylinder moves relatively slowly and the thrust output changes linearly, making it difficult to generate instantaneous high-intensity impact. This can easily lead to soft pushing and squeezing, which may actually exacerbate coal compaction and cause secondary blockage.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional hydraulic coal unloader to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a bidirectional hydraulic coal unloader, including a hopper body, with supports installed on both sides of the hopper body. Each support has a power storage component installed at its top. The power storage component includes a hydraulic cylinder fixedly connected to the top of the support. A moving block is fixedly connected to the telescopic end of the hydraulic cylinder. A traction column is fixedly connected to one side of the moving block. A right-angled trapezoidal block is abutted against the outer wall of one side of the traction column. A sliding rod is fixedly connected to one side of the right-angled trapezoidal block. A first spring is sleeved on the outer wall of the sliding rod. A push seat is slidably connected to the outer wall of the right-angled trapezoidal block. A contact column is fixedly connected to the side of the push seat near the hopper body. A second spring is connected to the side of the push seat away from the contact column. A spring seat is connected to the end of the second spring away from the push seat. The outer wall of the push seat is slidably connected to the top of the support. A matching inclined block is fixedly connected to one side of the top of the support. The inclined surface of the matching inclined block matches the inclined surface of the right-angled trapezoidal block.

[0007] Furthermore, both sides of the inner wall of the hopper body are slidably connected to coal slack plates, and multiple third springs are connected between the outer wall of each coal slack plate and the inner wall of the hopper body.

[0008] Furthermore, one end of the sliding rod is fixedly connected to the right-angled trapezoidal block, and the other end passes through the push seat and is slidably connected to the push seat. The two ends of the first spring are fixedly connected to the right-angled trapezoidal block and the push seat, respectively.

[0009] Furthermore, the second spring is sleeved on the outer wall of the contact post, and the spring seat is fixedly connected to the top of the bracket.

[0010] Furthermore, the end of the traction column is provided with an inclined surface that matches the right-angled trapezoidal block. When the moving block drives the traction column to move in the direction of the matching inclined surface block, the traction column will drive the push seat to move together through the right-angled trapezoidal block. When the moving block drives the traction column to move away from the matching inclined surface block, the right-angled trapezoidal block will slide on the inner wall of the push seat.

[0011] Furthermore, a first slider is provided at the bottom of the push base, and the push base is slidably connected to the bracket through the first slider.

[0012] Furthermore, a second slider is provided at the bottom of the movable block, and the movable block is slidably connected to the bracket through the second slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. When the hydraulic cylinder contracts, it drives the push seat to squeeze the second spring to store energy. After the right-angled trapezoidal block is triggered and released, the second spring releases its potential energy instantly, pushing the resisting column to bounce quickly, forming an instantaneous impact force far exceeding that of the direct drive of the hydraulic cylinder. This effectively avoids the soft pushing phenomenon and easily loosens stubborn lumps of coal.

[0014] 2. The impact force of the energy storage component is concentrated and instantaneous, which can quickly break up clumps of coal before it is further compacted; at the same time, the coal discharge plate, in conjunction with the third spring's reset vibration, can clean up residual loose coal a second time, providing double protection to avoid secondary blockage.

[0017] 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.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a bidirectional hydraulic coal feeder, including a hopper body 1, with supports 2 installed on both sides of the hopper body 1. Each support 2 has a power storage component installed at its top. The power storage component includes a hydraulic cylinder 3 fixedly connected to the top of the support 2. A moving block 4 is fixedly connected to the telescopic end of the hydraulic cylinder 3. The hydraulic cylinder 3 is fixed at the end of the support 2 away from the hopper body 1, with the telescopic end facing the hopper direction and rigidly connected to the moving block 4. The moving block 4 reciprocates horizontally with the telescopic movement of the hydraulic cylinder 3. A traction column 5 is fixedly connected to one side of the moving block 4. A right-angled trapezoidal block 6 is abutted against the outer wall of one side of the traction column 5. A sliding rod 7 is fixedly connected to one side of the right-angled trapezoidal block 6. A first spring 8 is sleeved on the outer wall of the sliding rod 7. A pusher 9 is slidably connected to the outer wall of the right-angled trapezoidal block 6. An abutment column 10 is fixedly connected to the side of the pusher 9 closest to the hopper body 1, and a power storage component is connected to the side of the pusher 9 away from the abutment column 10. There is a second spring 11, and the end of the second spring 11 away from the push seat 9 is connected to a spring seat 12. The outer wall of the push seat 9 is slidably connected to the top of the support 2. A matching inclined block 15 is fixedly connected to one side of the top of the support 2. The inclined surface of the matching inclined block 15 is adapted to the inclined surface of the right-angled trapezoidal block 6. The moving block 4 drives the traction column 5 to move synchronously. The traction column 5 moves synchronously after contacting the plane side of the right-angled trapezoidal block 6, driving the traction column 5 to translate in the direction of the matching inclined block 15. When the right-angled trapezoidal block 6 is displaced to the inclined surface area of ​​the matching inclined block 15, the second spring 11 is also fully charged. Under the action of the inclined surface thrust, the right-angled trapezoidal block 6 moves backward along the sliding rod 7 for a certain distance. At this time, the traction column 5 is contacted and disengaged. After the right-angled trapezoidal block 6 is released, the push seat 9 is quickly ejected towards the hopper body 1 under the action of the elastic potential energy of the second spring 11. The push seat 9 drives the contact column 10 to pop out synchronously and hit the coal unloading plate 13 to achieve coal unloading.

[0019] See Figure 2Both sides of the inner wall of the hopper body 1 are slidably connected to coal slurry plates 13. Multiple third springs 14 are connected between the outer wall of each coal slurry plate 13 and the inner wall of the hopper body 1. The coal slurry plate 13 is in direct contact with the coal. When the abutment column 10 hits the coal slurry plate 13, the coal slurry plate 13 slides towards the center of the hopper body 1, which can effectively loosen the clumps of coal, solve the coal blockage problem, and ensure the smooth conveying of coal. The third spring 14 is connected between the outer wall of the coal slurry plate 13 and the inner wall of the hopper body 1. After the coal slurry plate 13 completes the coal slurry action, the elastic force of the third spring 14 can drive the coal slurry plate 13 to automatically reset, so that the coal slurry plate 13 can continue to perform coal slurry work and ensure the continuity of the device.

[0020] See Figure 3 , Figure 4 One end of the sliding rod 7 is fixedly connected to the right-angled trapezoidal block 6, and the other end passes through the push seat 9 and is slidably connected to the push seat 9. The two ends of the first spring 8 are fixedly connected to the right-angled trapezoidal block 6 and the push seat 9 respectively. The sliding rod 7 passes through the push seat 9 and is slidably connected to it, providing guidance for the sliding of the right-angled trapezoidal block 6, ensuring that the right-angled trapezoidal block 6 will not deviate during the movement, and ensuring the stability of the inclined plane fit and the effective transmission of force.

[0021] See Figure 4 The second spring 11 is sleeved on the outer wall of the spring seat 12. The spring seat 12 is fixedly connected to the top of the bracket 2 to limit the radial displacement of the second spring 11 and prevent lateral displacement, twisting or misalignment during compression or rebound.

[0022] See Figure 3 The end of the traction column 5 is provided with an inclined surface that matches the right-angled trapezoidal block 6. When the moving block 4 drives the traction column 5 to move in the direction of the mating inclined surface block 15, the traction column 5 will drive the push seat 9 to move together through the right-angled trapezoidal block 6. When the moving block 4 drives the traction column 5 to move away from the mating inclined surface block 15, the right-angled trapezoidal block 6 will slide on the inner wall of the push seat 9.

[0023] See Figure 1 The bottom of the push seat 9 is provided with a first slider, and the push seat 9 is slidably connected to the bracket 2 through the first slider. The bottom of the moving block 4 is provided with a second slider, and the moving block 4 is slidably connected to the bracket 2 through the second slider. Both the first slider and the second slider can limit the deviation of the movement direction, ensuring that the movement is always driven along the preset straight trajectory, avoiding misalignment due to deviation, and ensuring the stability and accuracy of power transmission.

[0024] Working principle: When the hydraulic cylinder 3 retracts, it drives the moving block 4 and the traction column 5 to move synchronously towards the mating inclined block 15. The traction column 5 abuts against the plane side of the right-angled trapezoidal block 6, thereby driving the right-angled trapezoidal block 6 and the push seat 9 to move. The push seat 9 squeezes the second spring 11 sleeved on the outer wall of the spring seat 12, causing the second spring 11 to gradually accumulate force. When the right-angled trapezoidal block 6 moves to the inclined area of ​​the mating inclined block 15, the second spring 11 has completed its force accumulation. Under the inclined thrust of the mating inclined block 15, the right-angled trapezoidal block 6 moves backward along the sliding rod 7, and the first spring... Spring 8 is compressed, and at the same time, traction column 5 disengages from right-angled trapezoidal block 6. Right-angled trapezoidal block 6 is released, and push seat 9, under the action of the elastic potential energy of second spring 11, quickly pops out towards hopper body 1, causing the abutment column 10 on the side close to hopper body 1 to pop out simultaneously, hitting the coal slack plate 13 that is slidably connected to both sides of the inner wall of hopper body 1. The coal slack plate 13 slides towards the center of hopper, loosening the clumped coal to solve the coal blockage problem. The coal slack plate 13 is reset under the elastic force of the third spring 14 between its outer wall and the inner wall of hopper body 1, thus achieving vibration.
