The coal blocking plate is made of a rectangular steel plate. Each coal blocking plate leg includes a vertical steel plate and a triangular steel plate fixedly connected to the side surface of the vertical steel plate, which can prevent coal gangue from scattering and improve the conveying efficiency of the rubber belt conveyor.

[0004] In the above-mentioned technology, the angle adjustment of the baffle is relatively complex. The baffle with fixed angle cannot adapt to different material characteristics or conveying requirements in work, which may cause material scattering or accumulation. When the angle is not matched, the material may not be effectively concentrated in the middle of the conveying belt, causing unbalanced load or waste. At the same time, wet coal is easy to adhere to the surface of the baffle, forming accumulation and increasing the risk of blockage. The accumulated coal needs to be cleaned manually, increasing labor intensity and affecting production efficiency. Serious accumulation may cause the conveyor to stop, affecting overall operation.

[0028] When the user uses the device, the connecting seat 21 can be installed at the designated position on both sides of the conveyor body 1. When the material falls from above, the material will accumulate in the middle under the blocking of the baffle 221, and the material will be transported by the conveyor body 1. At this time, the user can start the first motor 23. The first motor 23 drives the belt pulley 25 to rotate through the belt, and then drives the threaded rod 27 to rotate. While the threaded rod 27 rotates, the sliding block 28 outside the threaded rod 27 will slide in the inside of the limiting frame 26. At the same time, under the support of the rotating support arm 24, the sliding block 28 will drive the bottom end of the connecting plate 29 to move, that is, the rotating angle of the connecting plate 29 can be changed, that is, the angle of the baffle 221 can be adjusted. Through the linkage of the first motor 23, the belt pulley 25, the threaded rod 27, the sliding block 28 and the connecting plate 29, the user can easily adjust the angle of the baffle 221 to adapt to different material flow and conveying needs, improve the operation flexibility, and the baffle 221 can guide the material to the middle of the conveyor body 1 to prevent the material from scattering, reduce waste and cleaning work, and improve the conveying efficiency.

The device is suitable for various materials and working conditions, especially suitable for coal and other easy-to-scatter materials, and has a wide range of applications.

[0029] As shown in Figure 1 Figure 5 The vibration mechanism includes a second motor 210, which is installed on the upper surface of the connecting plate 29.

The inner side of the end portion of the vibration column 215 is slidably connected with a vibration pull rod 216. The outer side of the end portion of the vibration pull rod 216 is fixedly connected with the baffle 221. The outer side of the end portion of the vibration pull rod 216 is fixedly connected with a first spring 217. The outer sides of the two ends of the first spring 217 are fixedly connected with the outer side of one end of the vibration column 215 and the inner side of one end of the vibration pull rod 216, respectively. The upper surface of the fixed seat 211 is fixedly connected with two limiting cylinders 218. The inner sides of the limiting cylinders 218 are slidably connected with limiting shafts 219. The outer side of the end portion of the limiting shaft 219 is fixedly connected with the lower surface of the baffle 221.

The outer sides of the two ends of the second spring 220 are fixedly connected with the outer side of one end of the limiting shaft 219 and the inner side of the bottom end of the limiting cylinder 218, respectively. The two groups of rotating shafts 212 and rotating pieces 213 are symmetrically arranged on both sides of the linkage rod 214.​

[0030] When there is material accumulation on the surface of the baffle 221, the user can start the second motor 210, which drives the rotating shaft 212 to rotate inside the fixed seat 211, and in turn drives the rotating part 213 to rotate. The rotating part 213 rotates while driving one end of the linkage rod 214 on the outer side of its end to perform circular motion, that is, to reciprocatingly push the vibration column 215. The vibration column 215 is pushed while compressing and releasing the elastic potential energy of the first spring 217, thereby driving the vibration pull rod 216 on the inner side of the end of the vibration column 215 to vibrate. At the same time, the limiting shaft 219 on both sides also compresses and releases the elastic potential energy of the second spring 220, further driving the baffle 221 on the outer side of the end of the limiting shaft 219 to vibrate.
