Description

Technical Field

[0001] The invention relates to the technical field of coal conveying devices in thermal power plants, in particular to an auger coal conveying device for a coal unloading ditch of a vehicle. Background Art

[0002] Coal transportation is a very important process in the thermal power generation process. Usually, the process of coal transportation in thermal power plants is that the coal transported by trucks is poured into the coal unloading ditch through a grate, and then the impeller coal feeder is used to push the coal in the coal unloading ditch onto the belt conveyor on the lower level. The belt conveyor then transports the coal to the coal drop hopper, and then the coal falls into the coal drop hopper for subsequent processing.

[0003] For example, a coal conveying device for a coal unloading trench of a thermal power plant with an auger is disclosed with the announcement number CN207810778U, which includes an auger coal conveyor and a guide trough; an auger coal conveyor is provided at the discharge port at the bottom of the coal unloading trench, a guide trough is fixed at the discharge port of the auger coal conveyor, and a coal drop barrel is provided at the discharge end of the belt conveyor. The application uses an auger coal conveyor to convey coal while breaking and mixing the coal that is stuck together, and then smoothly conveys it to the belt conveyor through a closed arc guide trough, which reduces the impact of coal on the belt conveyor and avoids damage and deviation of the belt conveyor. At the same time, it increases the conveying stroke of coal, makes it easier to increase the dispersion of coal, accelerates the evaporation of water, and thus reduces the adhesion of coal. In winter, by installing a heater on the belt conveyor, the temperature of coal is increased, which makes it easier to evaporate water and avoids coal sticking to the inner wall of the coal drop barrel and causing blockage, thereby reducing the workload of maintaining the conveying equipment.

[0004] The traditional coal transportation device is completed by a belt conveyor. The coal unloaded from the car needs to be transferred to a designated open space. After a long time, the coal in this area accumulates more and more. When the height of the accumulation exceeds the machine discharge port, it is easy to block the discharge port. Since the belt conveyor is large in size and inconvenient to move and carry, the operator is required to supervise and protect this place at all times. If necessary, certain measures need to be taken to ensure the smoothness of coal transportation. The operation is cumbersome and the work efficiency is low.

[0005] Therefore, we propose a car unloading coal ditch auger coal conveying device to solve the above-mentioned problems. Summary of the invention

[0027] The feeding mechanism 2 includes a feeding cylinder 21 adapted to the coal conveying cylinder 11, the upper end of the feeding cylinder 21 is connected to and installed with a first hollow hemisphere 22, the upper end of the first hollow hemisphere 22 is connected to and installed with a second hollow hemisphere 23, the upper end of the second hollow hemisphere 23 is connected to and installed with a feeding hopper 24, the upper diameter of the feeding hopper 24 is large and the lower diameter is large, and the feeding hopper 24 is adapted to the coal unloading port of the automobile. When unloading coal, the coal enters the feeding hopper 24, the second hollow hemisphere 23, the first hollow hemisphere 22, and the feeding cylinder 21 in sequence and enters the coal conveying cylinder 11, which is convenient for transporting the coal on the automobile to the coal conveying cylinder 11, and can accommodate more coal at one time.

[0028] A conveying mechanism 4 is arranged inside the coal conveying mechanism 1, and the conveying mechanism 4 includes an auger shaft 41 rotatably installed inside the coal conveying cylinder 11, and an auger blade 42 is fixedly installed on the outer periphery of the auger shaft 41. One side of the auger shaft 41 is connected to a motor. After the motor is turned on, the auger shaft 41 and the auger blade 42 rotate inside the coal conveying cylinder 11, and the coal in the coal conveying cylinder 11 can be conveyed to the position of the discharge port 12. Finally, the coal is discharged from the discharge port 12, and the conveying of the device is completed, which is convenient for completing the coal conveying work.

[0029] The first hollow hemisphere 22 and the second hollow hemisphere 23 are interference fit, and the two are rotatably connected and interconnected, that is, the feed hopper 24 and the coal conveying cylinder 11 can be rotated in any direction, so that the direction and position of the coal conveying cylinder 11 can be adjusted. There is no need to shut down the device, and other conveying points can be changed during coal transportation, which is easy to operate and greatly reduces the blockage of the discharge port 12 due to excessive coal accumulation in the unloading area, making it easy to use.

[0030] An arc rod 43 is fixedly installed at one end of the auger shaft 41, and the arc rod 43 is arranged on one side of the discharge port 12. When the auger shaft 41 rotates, it also drives the arc rod 43 to rotate.

[0031] Example 2: Please refer to Figure 2-Figure 7 The outer peripheries of the feeding cylinder 21 and the feeding hopper 24 are fixedly installed with mounting plates 25, and a bellows 26 is installed between the two mounting plates 25.

[0032] The conveying mechanism 4 also includes a scraper 44 fixedly mounted on the outer periphery of the arc rod 43. The scraper 44 has a large contact area with the coal. After the auger shaft 41 rotates one circle, the scraper 44 flattens the top of the coal, thereby limiting the height of the accumulated coal.

[0033] A stabilizing mechanism 5 is provided on one side of the coal conveying mechanism 1. The stabilizing mechanism 5 is fixedly installed on a second side plate 51 on one side of the coal conveying cylinder 11 and a clamping ring body 52 fixedly installed at one end of the second side plate 51. The clamping ring body 52 is adapted to the coal conveying cylinder 11, so as to facilitate sealing one end of the coal conveying cylinder 11. The auger shaft 41 rotates between the first side plate 14 and the second side plate 51, and the force at both ends is uniform, thereby ensuring the stability of the rotation of the auger shaft 41. Two connecting blocks 53 are fixedly installed on one side of the second side plate 51, and connecting shafts 54 are fixedly installed on the outer sides of the two connecting blocks 53. Stabilizing rods 55 are fixedly installed on the lower ends of the two connecting shafts 54, thereby ensuring the stability of the second side plate 51.

[0034] A supporting mechanism 6 is provided at the lower end of the stabilizing mechanism 5. The supporting mechanism 6 includes a supporting rod 61 provided at the lower end of the stabilizing rod 55. Limiting blocks 62 are fixedly installed at the upper ends of the two supporting rods 61, and supporting blocks 63 are fixedly installed on both sides of the lower ends of the supporting rods 61.

[0035] Under the action of the second side plate 51, the clamping ring body 52, the connecting block 53, the connecting shaft 54, the stabilizing rod 55, the support rod 61, the limit block 62 and the support block 63, the unloading end of the coal conveying cylinder 11 has a certain supporting force, and a universal wheel 68 is rotatably installed on one side of the support rod 61, and the universal wheel 68 is rotatably installed on the ground. When the coal conveying cylinder 11 adjusts the conveying direction, the first hollow hemisphere 22 and the second hollow hemisphere 23 at one end of the coal conveying cylinder 11 rotate, the position of the feed hopper 24 remains unchanged, and the universal wheel 68 at the end of the discharge port 12 rotates adaptively, which further increases the flexibility and stability of the adjustment of the coal conveying cylinder 11.

[0036] Example 3: Please refer to Figure 2-Figure 7 A connecting rod 45 is fixedly installed on the outer periphery of the auger shaft 41. The connecting rod 45 is arranged on the outer side of the coal conveying cylinder 11. When the auger shaft 41 rotates, the connecting rod 45 rotates together.

[0037] A rack 56 is fixedly installed at the lower end of the stabilizing rod 55, and a gear 64 is rotatably installed in the middle of the supporting rod 61. The gear 64 is meshed with the rack 56. A rotating disk 66 is coaxially arranged at one end of the gear 64. A plurality of blocks 67 are fixedly installed on the outer periphery of the rotating disk 66. The blocks 67 are relatively long and can mesh with the connecting rod 45 at any position on the rack 56. A universal wheel 68 is fixedly installed on one side of the rotating disk 66.

[0038] When the auger shaft 41 rotates one circle and the connecting rod 45 rotates to the block 67, the connecting rod 45 touches the block 67, driving the block 67, the rotating disk 66, and the gear 64 to rotate slightly. The gear 64 rotates along the rack 56, and the support rod 61, the limit block 62, the support block 63, and the universal wheel 68 on one side are displaced to avoid the discharge port 12.

[0039] When the gear 64 moves to the end point of the rack 56, the support rod 61, the limit block 62, and the support block 63 are restricted by the rack 56, and the universal wheel 68 still rotates, which will drive the stabilizing mechanism 5 and the supporting mechanism 6 to move as a whole, that is, one side of the coal conveying cylinder 11 can automatically adjust the direction, and the first hollow hemisphere 22 and the second hollow hemisphere 23 rotate adaptively without manual operation. As the auger shaft 41 rotates, the device automatically moves left and right, and the height of the coal piled in the same area will not be too high, which reduces the workload of the workers and greatly improves the work efficiency.

[0040] The stabilizing rod 55 has a C-shaped structure and is provided with a linear slide groove 57. A slider 65 is fixedly installed on the inner wall of the support rod 61. When the gear 64 rotates, the slider 65 slides in the linear slide groove 57, so that the support rod 61 always has a support point, thereby ensuring the stability of the device.

[0041] Example 4: Please refer to Figure 5-Figure 8 Two spiral grooves 58 are provided on the inner wall of the second side plate 51, and the two spiral grooves 58 are connected end to end. A protrusion 46 is fixedly installed on the outer wall of the auger shaft 41, and the protrusion 46 is slidably installed in the spiral groove 58. When the auger shaft 41 rotates, the protrusion 46 moves back and forth on the spiral groove 58, so the second side plate 51 and the support rod 61 as a whole will also move forward and backward, pushing the coal accumulated in the area, increasing the range of movement of the support rod 61, and facilitating the support rod 61 to slide left and right.

[0042] A sliding mechanism 7 is provided on one side of the coal conveying mechanism 1, and the sliding mechanism 7 includes a sliding cylinder 71 slidably mounted on the outer periphery of the coal conveying cylinder 11, and a baffle 72 is fixedly mounted on one end of the sliding cylinder 71. The baffle 72 is arranged on one side of the support rod 61 to facilitate blocking the discharge port 12 and the support rod 61 to prevent coal from splashing onto the support rod 61 and causing the device to get stuck.

[0043] A movable ring body 74 is fixedly installed at one end of the sliding cylinder 71 away from the baffle 72 , and the movable ring body 74 is slidably installed on the outer periphery of the coal conveying cylinder 11 . A discharge cylinder 73 is connected and installed at the lower end of the sliding cylinder 71 , and the discharge cylinder 73 is slidably installed in the discharge port 12 .

[0044] The baffle 72 is also fixedly connected to the connecting block 53, that is, the sliding cylinder 71 and the second side plate 51 are an integral structure. During the movement of the second side plate 51, the sliding cylinder 71 slides back and forth on the coal conveying cylinder 11, that is, the position of the discharge cylinder 73 can be changed, ensuring that the unloading position of the device is not fixed each time, having a height limiting function, reducing blockage due to coal accumulation, and having a good use effect.
