When the pushing block contacts the fixed shaft, the pushing block can push the fixed shaft to rotate along the axis point of the rotating shaft C, so that the fixed shaft will also drive the swing block to rotate synchronously. At this time, the connecting block A can be driven to rise synchronously under the action of the connecting shaft A. The connecting block A can pull the compression block to rise under the action of the supporting seat B, the connecting block B and the long shaft. At this time, when the compression block is not limited to the loading port on the left side of the compression box, the collection in the collection box can be guided by gravity. The corner debris inside the channel is discharged into the compression box.

[0020] 2. The present invention is provided with a scraping mechanism, and the motor is started to work, so that the output end of the motor can drive the output shaft to rotate, and the output shaft drives the disc to rotate, so that the short shaft can make a circular motion along the circle of the disc. At this time, the short shaft can push the movable groove to move left and right, and the movable groove can drive the scraping block to scrape the corner debris stuck to the inner wall of the collecting channel, which can further enhance the smoothness of the corner debris during the cleaning process, and can effectively reduce the accumulation of corner debris inside the collecting channel to cause blockage, further improve the stability during the collection process, and do not need manual cleaning, thereby improving the convenience of cleaning.

At this time, the rotating shaft A can drive the half gear to rotate through the bevel gear assembly and the rotating shaft B. When the half gear is engaged with the complete gear, it can drive the threaded rod to rotate, so that the rotational motion of the threaded rod is converted into the linear motion of the load-bearing block, thereby increasing the space for compressing the corner debris, and further compressing the corner debris better. When the two are not engaged, the load-bearing block will not move, and the corner debris can be evenly compacted on the top of the load-bearing block, so that the load-bearing block can be evenly descended according to the compaction rhythm, thereby improving the synchronization of the lifting device during operation and facilitating the operation of the staff.
