[0040] Working principle:
[0041] When in use, first connect the feed pipe 1 to the limestone powder feed port, then connect the discharge pipe 5 to the discharge port, and then start the fan 2, so that the fan 2 drives the limestone powder in the pipeline to move, thereby completing the basic transportation work. The entire transportation device is fixed to the ground by the bracket 4, thereby maintaining the position of the transportation device. The limestone powder in the feed pipe 1 is screened by the screening mechanism 6 during the process of passing through the fixed cylinder 3. During the screening process, the limestone powder may accumulate, causing the limestone powder to block the screening mechanism 6. At the same time, the oscillation mechanism 7 is used to transmit vibration to the screening mechanism 6, thereby vibrating the accumulated limestone powder to disperse it, thereby clearing the blockage. The limestone powder screened by the screening mechanism 6 is then transported to the discharge port through the discharge pipe 5, thereby completing the transportation work.
[0042] After the limestone powder reaches the filter plate 61 driven by the fan 2, it is initially screened by the filter plate 61 and then reaches the screening plate 67. After secondary screening by the screening plate 67, the limestone powder reaches the fixed plate 68. When the limestone powder reaches the fixed plate 68, the position of the screen plate 66 can be adjusted by the sliding adjustment handle 64 to control the amount of limestone powder passing through, thereby realizing quantitative transportation.
[0043] Simply pull the plug 63 out of the fixed tube 3 to unlock the adjusting handle 64, then rotate the adjusting handle 64 to drive the sieve plate 66 to slide synchronously in the fixed shell 65, so that the holes on the sieve plate 66 are offset from the holes on the fixed plate 68, thereby achieving control of the amount of limestone powder passing through. After the adjusting handle 64 is rotated, simply insert the plug 63 through the adjusting handle 64 again and insert it into the fixed tube 3 to re-fix the adjusting handle 64, thereby fixing the position of the sieve plate 66.
[0044] During the process of screening limestone powder, the screening mechanism 6 may block the subsequent limestone powder by the previous limestone powder, thus causing a blockage problem. However, the oscillation mechanism 7 is also working synchronously at the same time to prevent the limestone powder from being blocked. During the process of the fan 2 transmitting the airflow to the feed pipe 1, the airflow will first contact the runner 72, and the fixed shaft 71 is used to limit the position of the runner 72. Therefore, when the runner 72 rotates, the blades on the runner 72 will hit the block 73, and because the block 73 is fixed on the oscillation rod 75, the oscillation rod 75 will vibrate due to the hitting of the blades. A fixing frame 74 and a connecting frame 76 are provided on the oscillation rod 75, both of which are used to limit the position of the oscillation rod 75, and because there is a gap between the two and the oscillation rod 75, the vibration of the oscillation rod 75 will not be blocked, and only the height position of the oscillation rod 75 will be limited.
[0045] The outer side of the bottom of the oscillating rod 75 is connected to the filter plate 61 through a connecting block 77, and the bottom is connected to the screening plate 67. Therefore, the oscillating rod 75 will transfer the vibration of the oscillating rod 75 to the filter plate 61 and the screening plate 67, so that the filter plate 61 and the screening plate 67 vibrate synchronously, thereby shaking the accumulated limestone powder, increasing the permeability of the limestone powder, and because a chute is provided on the limiting ring 62, during the vibration of the screening plate 67, the limiting ring 62 will not restrict the vibration of the screening plate 67.
