Description

Technical Field

[0001] This utility model relates to the field of material handling devices, and more specifically, to an intelligent material handling device for coal yards. Background Technology

[0002] Coal mines are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to excavate roadways underground to mine the coal. This is called an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine the coal. This is called an open-pit coal mine. In order to ensure the stability and continuity of operation, coal-fired power plants will store a certain amount of coal. Therefore, each coal-fired power plant has a coal yard. The strip coal yard adopts separate stacking. When processing is required, mechanical stacking and reclaiming devices are used to realize the storage of coal in the coal yard.

[0003] A search revealed an existing patent (publication number: CN218981727U) that discloses an intelligent coal yard material handling device, comprising a conveyor belt, a fixed frame mounted on the surface of the conveyor belt, a rotating block mounted on the inner wall of the fixed frame, a material-pulling scoop mounted on the surface of the rotating block, a first motor mounted on the surface of the fixed frame, a crushing shell mounted on the surface of the conveyor belt, and a first crushing gear mounted on the inner wall of the crushing shell. By setting the material-pulling scoop, it is possible to conveniently handle coal piles in the coal yard. By setting the crushing shell, the coal transported by the material-pulling scoop will undergo crushing processing through the crushing shell, ensuring that the coal removed by this material handling device has a uniform mass and size. By setting the fixed block and fixing bolts, the crushing shell can be stably fixed to the surface of the conveyor belt, allowing for convenient installation when needed and convenient disassembly when not needed. The receiving frame can store the fixing bolts, preventing them from being lost.

[0004] Existing intelligent coal yard reclaiming devices generally utilize bucket wheels for coal mining. However, traditional bucket wheels tend to spill coal during rotation, failing to collect all of it onto the conveyor belt. This results in low reclaiming efficiency and significant dust pollution. Furthermore, existing coal yard reclaiming devices typically lack a coal crushing structure or have a very simple crushing structure, making it impossible to perform crushing operations of different specifications. Moreover, the aforementioned cited patent documents do not propose any solutions to address these issues.

[0005] Therefore, an intelligent coal yard material handling device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an intelligent coal yard material handling device to solve the problems mentioned in the background art.

[0007] To achieve the above object, the present utility model provides the following technical solution: An intelligent coal yard material taking device, including a conveying frame, within which a conveyor belt is installed, and one end of the conveying frame is fixed with a mounting frame through a connection. On one side of the mounting frame, there is a support, and a material taking ring is rotatably installed between the support and the mounting frame. At one end of the material taking ring away from the conveyor belt inside, there is a support frame welded, and at one end of the support away from the conveyor belt, a driving motor is fixed. The output end of the driving motor is connected to the material taking ring through a rotating shaft, and a bucket wheel is uniformly fixed on the outer periphery of the material taking ring;

[0008] At the other end of the conveying frame, there is a hinged crushing seat, and at the bottom of the crushing seat, there is an integrally connected discharge hopper. At one end of the crushing seat away from the conveying frame inside, there is a first crushing roller, and at one end of the crushing seat close to the conveying frame, a second crushing roller is installed. At a position on one side of the crushing seat close to the second crushing roller, a second crushing motor is fixed, and the output end of the second crushing motor is connected to the second crushing roller through a rotating shaft. At one end of the crushing seat close to the conveying frame, a hydraulic jack is hinged, and the output end of the hydraulic jack is hinged to the bottom of the conveying frame. An adjusting frame is installed on the outside of the crushing seat.

[0009] Preferably, at one end of the crushing seat away from the conveying frame, there is an integrally connected mounting plate, and adjusting grooves are opened on both side walls of the crushing seat. The adjusting grooves are arranged in parallel, and both ends of the mounting shaft of the first crushing roller penetrate through the adjusting grooves and are rotatably connected to the adjusting frame. On one side of the adjusting frame, a first crushing motor is fixed, and the output end of the first crushing motor is connected to the mounting shaft of the first crushing roller through a rotating shaft.

[0010] Preferably, the adjusting frame is designed in a "C" shape, and the distance between the two side plates of the adjusting frame fits the width of the crushing seat. At the central position of one end of the adjusting frame away from the crushing seat, a hydraulic telescopic rod is fixed, and the output end of the hydraulic telescopic rod is fixed to the outer wall of the crushing seat through a bolt.

[0011] Preferably, on the mounting frame above the conveyor belt, a guiding frame is fixed through a bolt, and at the top of the guiding frame, there is an inclined guiding part. The top of the inclined guiding part extends into the inside of the material taking ring and fits the inner top surface of the material taking ring. The bottom of the guiding frame fits the upper surface of the conveyor belt, and at one end of the guiding frame close to the crushing seat, there is a discharge port.

[0012] Preferably, on one side of the mounting frame away from the support, a conveying motor is installed, and the output end of the conveying motor is connected to the conveying roller inside the conveyor belt through a rotating shaft.

[0013] Preferably, on one side of the mounting frame close to the material taking ring, a baffle is fixed through a connecting frame, and the baffle is designed in an arc shape. The outer wall of the baffle fits the inner wall of the material taking ring.

[0014] Preferably, the bucket wheels are all fixed to the material receiving ring by bolts, and the surface of the material receiving ring is provided with a discharge port corresponding to the bucket wheel near the position of the bucket wheel. The digging end of the bucket wheel is uniformly provided with crushing teeth.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with existing technologies, this intelligent coal yard material handling device sets the material handling ring on the side of the conveyor belt, with bucket wheels evenly installed on the surface of the material handling ring. A guide frame is set above the conveyor belt. The coal excavated by the bucket wheels moves to the top of the guide frame as the material handling ring rotates. Under its own gravity, it falls from the discharge port, enters the guide frame along the inclined guide section, and finally falls onto the conveyor belt. During the material handling process, when the bucket wheel has not rotated to the top of the guide frame, the corresponding discharge port is blocked by a baffle to prevent the coal from scattering. This ensures that all the excavated coal falls onto the conveyor belt, resulting in higher material handling efficiency and less dust pollution generated during material handling.

[0017] 2. Compared with existing technologies, this intelligent coal yard material handling device is equipped with a crushing seat. The first crushing roller and the second crushing roller inside the crushing seat rotate relative to each other, which can crush the transported coal. The first crushing roller is connected to the adjusting frame, and its position can be adjusted as the adjusting frame moves, thereby adjusting the distance between the first crushing roller and the second crushing roller, controlling the crushing accuracy of the coal, and obtaining coal particles of different sizes, which is more practical.

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.

[0024] Example 1

[0025] As attached Figure 1 The intelligent material handling device for a coal yard shown includes a conveyor frame 5, a conveyor belt 6 installed inside the conveyor frame 5, and a mounting frame 8 fixed to one end of the conveyor frame 5. A bracket 801 is provided on one side of the mounting frame 8, and a material handling ring 12 is rotatably installed between the bracket 801 and the mounting frame 8.

The output end of the drive motor 13 is connected to the material handling ring 12 through a rotating shaft, and bucket wheels 19 are evenly fixed to the outer circumference of the material handling ring 12.

[0026] The other end of the conveyor frame 5 is hinged to a crushing seat 1, and the bottom of the crushing seat 1 is integrally connected to a discharge hopper 4. The crushing seat 1 is equipped with a first crushing roller 17 at the end away from the conveyor frame 5, and a second crushing roller 18 is installed at the end of the crushing seat 1 close to the conveyor frame 5.

An adjusting frame 2 is installed on the outside of the crushing seat 1.

[0027] Among them, the hydraulic jack 7 can drive the conveyor frame 5 to rotate, which makes it easier to adjust the tilt angle of the conveyor frame 5 and make material picking more convenient and accurate. The first crushing roller 17 and the second crushing roller 18 rotate relative to each other under the drive of the first crushing motor 15 and the second crushing motor 16, respectively, which can crush and process the transported coal.

[0028] Example 2

[0029] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0030] As a preferred embodiment, a mounting plate 101 is integrally connected to one end of the crushing seat 1 away from the conveyor rack 5, and adjustment grooves 102 are formed on both side walls of the crushing seat 1. The adjustment grooves 102 are arranged in parallel, and the mounting shafts at both ends of the first crushing roller 17 penetrate through the adjustment grooves 102 and are rotatably connected to the adjustment frame 2. A first crushing motor 15 is fixed on one side of the adjustment frame 2, and the output end of the first crushing motor 15 is connected to the mounting shaft of the first crushing roller 17 through a rotating shaft; further, the design of the adjustment groove 102 enables the first crushing roller 17 to be adjusted in position along with the adjustment frame 2, adjusts the distance between the first crushing roller 17 and the second crushing roller 18, controls the precision of coal crushing, and obtains coal particles with different particle sizes, with stronger practicability.

[0031] As a preferred embodiment, the adjustment frame 2 is designed in a "U" shape, and the distance between the two side plates of the adjustment frame 2 coincides with the width of the crushing seat 1. A hydraulic telescopic rod 3 is fixed at the central position of one end of the adjustment frame 2 away from the crushing seat 1, and the output end of the hydraulic telescopic rod 3 is fixedly connected to the outer wall of the crushing seat 1 through a bolt; further, the coinciding width makes the movement of the adjustment frame 2 more stable, and it is not easy to shake or tilt. When the hydraulic telescopic rod 3 extends, the distance between the adjustment frame 2 and the crushing seat 1 can be increased, that is, the first crushing roller 17 is driven to move, so that the distance between the first crushing roller 17 and the second crushing roller 18 is increased, and the adjustment is very convenient.

[0032] As a preferred embodiment, a material guiding frame 10 is fixedly connected to the mounting frame 8 above the conveyor belt 6 through a bolt, and an inclined material guiding part 1001 is arranged at the top of the material guiding frame 10. The top of the inclined material guiding part 1001 extends into the inner part of the material taking ring 12 and is in contact with the top surface inside the material taking ring 12. The bottom of the material guiding frame 10 is in contact with the upper surface of the conveyor belt 6, and a discharge port 1002 is arranged at one end of the material guiding frame 10 close to the crushing seat 1; further, the top of the inclined material guiding part 1001 of the material guiding frame 10 extends into the inner part of the material taking ring 12 and is in contact with the top surface inside the material taking ring 12. After the coal moves to the upper part of the material guiding frame 10 along with the rotation of the material taking ring 12, it can be discharged from the discharge port 1201 and enter the material guiding frame 10 along the inclined material guiding part 1001, avoiding the scattering of coal, enabling all the excavated coal to fall onto the conveyor belt 6, with higher material taking efficiency and less dust pollution generated during material taking.

[0033] As a preferred embodiment, a conveyor motor 9 is installed on one side of the mounting frame 8 away from the support 801, and the output end of the conveyor motor 9 is connected to the conveyor roller inside the conveyor belt 6 through a rotating shaft; further, when the conveyor motor 9 works, it drives the conveyor roller inside the conveyor belt 6 to rotate, thereby transporting the coal by the conveyor belt 6, and the design is more reasonable.

[0034] In a preferred embodiment, a baffle 14 is fixed to the side of the mounting frame 8 near the material-receiving ring 12 via a connecting frame 11. The baffle 14 has an arc-shaped design, and its outer wall fits against the inner wall of the material-receiving ring 12. Furthermore, the design of the fitting baffle 14 ensures that during the material-receiving process, when the bucket wheel 19 has not rotated above the guide frame 10, the corresponding discharge port 1201 will be blocked by the baffle 14 to prevent coal from scattering. This allows all the excavated coal to fall onto the conveyor belt 6, resulting in higher material-receiving efficiency and less dust pollution generated during material-receiving.

[0035] In a preferred embodiment, the bucket wheels 19 are all fixed to the material-collecting rings 12 by bolts, and the material-collecting rings 12 are all provided with discharge ports 1201 corresponding to the bucket wheels 19 at positions close to the bucket wheels 19. The digging ends of the bucket wheels 19 are all uniformly provided with crushing teeth 1901. Furthermore, the design of the crushing teeth 1901 makes the material-collecting of the bucket wheels 19 smoother and the design more reasonable.

[0036] The working process of this utility model is as follows:

[0037] In use, the hydraulic jack 7 drives the conveyor frame 5 to rotate, facilitating the adjustment of the conveyor frame 5's inclination angle and making material collection more convenient and accurate. The drive motor 13 drives the material collection ring 12 to rotate, and the bucket wheel 19 rotates with the material collection ring 12 to dig out the coal. After the coal moves above the guide frame 10 with the rotation of the material collection ring 12, it can be discharged from the discharge port 1201 and enter the guide frame 10 along the inclined guide section 1001, finally falling onto the conveyor belt 6. It is then transported out by the conveyor belt 6 through the discharge port 1002 of the guide frame 10. The coal is transported by the conveyor belt 6 to the crushing seat 1. The first crushing roller 17 and the second crushing roller 18 rotate relative to each other under the drive of the first crushing motor 15 and the second crushing motor 16, respectively, to crush the transported coal. During crushing, the hydraulic telescopic rod 3 works to adjust the distance between the adjusting frame 2 and the crushing seat 1, that is, to drive the first crushing roller 17 to move and adjust the distance between the first crushing roller 17 and the second crushing roller 18 so that the crushed particle size meets the requirements.

[0038] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
