[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1 to 5 As shown, a coal bunker discharge guide plate structure with adjustable angle includes: The bottom plate 1 is connected in an L-shape by a horizontally arranged horizontal plate 101 and a vertically arranged vertical plate 102. The upper surface of the horizontal plate 101 is provided with a movable component 2. The first adjustment component 3 is connected to the horizontal plate 101 through the movable component 2. The top of the vertical plate 102 is connected to the second adjustment component 4. The moving assembly 2 includes a limiting groove 203, a threaded rod 205, a driving motor 204, and a limiting block 201 provided with a threaded groove 202. The limiting block 201 provided with the threaded groove 202 and the threaded rod 205 are arranged in the limiting groove 203. The threaded rod 205 is connected to the limiting block 201 through the threaded groove 202. The limiting block 201 is driven by the threaded rod 205 for transmission. The driving motor 204 is arranged on the horizontal plate 101, and the driving end of the driving motor 204 is fixedly connected to the threaded rod 205 for driving the limiting block 201 to move. Since the limiting block 201 and the limiting groove 203 restrict the limiting block 201 from rotating, the limiting block 201 is driven to move by the driving motor 204. A variety of drive modes can be adopted, including hydraulic drive, electric drive, and hydraulic drive in parallel. The drive mode can be flexibly switched during operation. Electric drive is selected in scenarios where the power supply is stable and high adjustment accuracy is required. Hydraulic drive can be used to improve applicability in working conditions that require large impact forces and fast response speeds. The combination of electric drive and hydraulic drive can reduce articulation torque and workpiece pressure, thereby improving stability. The arc-shaped plate 5 is connected to the first adjustment component 3 on its lower surface and to the second adjustment component 4 on its side near the vertical plate 102. The arc-shaped structure of the arc-shaped plate 5 is conducive to the circulation of coal and can reduce the smoke and dust generated when the coal circulates. A dust-proof net 10 is fixedly connected to the top of the arc-shaped plate 5 to expand the flow space of the coal and prevent coal blockage. At the same time, it can absorb the smoke and dust generated when the coal slides down, thereby improving environmental protection. A soft contact plate 11 is provided on the upper surface of the arc-shaped plate 5 to assist in connecting the equipment on both sides of the arc-shaped plate 5 to prevent leakage and equipment damage. A vibration motor 9 is provided on the lower surface of the arc-shaped plate 5 to drive the arc-shaped plate 5 to vibrate, increase the speed of the coal sliding down, and prevent coal stacking and blockage. The first adjusting component 3 is connected to the moving component 2, and includes a first arc block 301, a fixed shaft 302, a connecting ring 303, a push rod 304, a pneumatic cylinder 305, a second arc block 306, a rotating rod 307, a moving plate 309, and a third arc block 308. The two first arc blocks 301 are fixedly connected to the lower surface of the arc plate 5, the fixed shaft 302 is fixedly connected between the two first arc blocks 301, the connecting ring 303 is movably connected to the fixed shaft 302, and the lower surface of the connecting ring 303 is sequentially connected with a push rod 304, a pneumatic cylinder 305, a second arc block 306, a second arc block 306 with a rotating rod 307 on both sides, and two third arc blocks 308 on the top. The movable plate 309 of the arc block 308 and the rotating rod 307 are movably connected with the two third arc blocks 308. The push rod 304 is used to adjust the lifting of the arc plate 5. The transmission end of the pneumatic cylinder 305 is fixedly connected to the push rod 304. The push rod 304 is driven by the pneumatic cylinder 305 to realize the lifting of the arc plate 5. The transmission method can adopt hydraulic assisted pneumatic transmission. The pneumatic cylinder 305 is hinged to the movable plate 309 through the third arc block 308, the second arc block 306 and the rotating rod 307. When the push rod 304 is extended to a certain length, since the pneumatic cylinder 305 and the movable plate 309 are hinged, the movable plate 309 can also drive the angle adjustment of the arc plate 5 when it moves. The movable plate 309 of the first adjustment assembly 3 is fixedly connected to the limit block 201 of the movable assembly 2. When the drive motor 204 drives the limit block 201 to move, the movable plate 309 moves along with the limit block 201, thereby realizing the movement of the curved plate 5. When the push rod 304 extends to a certain length, the drive motor 204 drives the movable plate 309 to move and also adjust the angle of the curved plate 5, thereby facilitating the adjustment of the feeding rate and direction of the coal. The second adjustment assembly 4 is provided at the top of the vertical plate 102 and includes a connecting shaft 402 and a fixing ring 401. The two fixing rings 401 are fixedly connected to the top of the vertical plate 102. The connecting shaft 402 is movably connected between the two fixing rings 401. The upper part of the connecting shaft 402 is fixedly connected to the curved plate 5. The curved plate 5 and the vertical plate 102 are hinged together through the fixing ring 401 and the connecting shaft 402. The two side surfaces of the fixed shaft 302 are respectively fixedly connected with the first shock-absorbing cotton 6, the two side surfaces of the rotating rod 307 are respectively fixedly connected with the second shock-absorbing cotton 7, and the two side surfaces of the connecting shaft 402 are respectively fixedly connected with two pieces of third shock-absorbing cotton 8.
[0021] The working process of the present invention is as follows: The curved plate 5 is driven to a suitable position by the moving component 2, that is, the driving motor 204 drives the limit block 201 to move smoothly on the threaded rod 205, and the height and inclination angle of the curved plate 5 are adjusted by the first adjusting component 3 and the second adjusting component 4, that is, the height of the curved plate 5 is adjusted by the push rod 304 and the pneumatic cylinder 305, and the inclination angle of the curved plate 5 is adjusted by the fixing ring 401 and the connecting shaft 402. When the height of the curved plate 5 is constant, the driving motor 204 drives the moving plate 309 to move and the angle of the curved plate 5 can also be adjusted.
