In other embodiments, the support member may only support the outer arc surface of the dust collection pipe 2 or only support the inner arc surface of the dust collection pipe 2, and may also be U-shaped or I-shaped.

[0032] With reference to Figure 2 The adjusting device 4 comprises a first adjusting assembly 41 and a second adjusting assembly 42 for adjusting the positions of the support in two intersecting directions, respectively, and the second adjusting assembly 42 is connected with the support. The dust fall pipe 2 is provided with a mounting block on the connecting plate near one end of the intensive mixer. To adjust the position of the support ring 3 in the vertical direction, the first adjusting assembly 41 comprises a first fixed rod 411 fixed on the mounting block, a first positioning rod 412 slidingly arranged on the first fixed rod 411, and a first fixing member 413 for fixing the relative positions of the first fixed rod 411 and the first positioning rod 412. Specifically, the first fixed rod 411 is hollow, the first positioning rod 412 is slidingly inserted into the first fixed rod 411, and the length directions of the first fixed rod 411 and the first positioning rod 412 are arranged along the vertical direction. In the embodiment, the first fixing member 413 is a first bolt threaded through the first fixed rod 411, and the shank end of the first bolt abuts against the peripheral wall of the first positioning rod 412.

Specifically, the second fixed rod 421 is hollow, and the length direction thereof is perpendicular to the length direction of the first positioning rod 412. The second positioning rod is slidingly inserted into the first fixed rod 411, and the end of the second positioning rod away from the second fixed rod 421 is fixed with a mounting sleeve fixedly sleeved on the support ring 3. The second fixing member is a second bolt threaded through the second fixed rod 421, and the shank end of the second bolt abuts against the peripheral wall of the second positioning rod.

[0035] When the strong mixer needs to be started, the first screw is driven to rotate until its screw end is no longer in contact with the first positioning rod 412, the second screw is driven to rotate until its screw end is no longer in contact with the second positioning rod, the support ring 3 drives the dust fall pipe 2 to move to a curved shape, at this time the first positioning rod 412 slides in the first fixed rod 411, the second positioning rod slides in the second fixed rod 421, under the action of gravity, the support ring 3 and the inner arc surface of the curved part of the dust fall pipe 2 abut, then the first screw is screwed to abut against the side wall of the first positioning rod 412, and the second screw is screwed to abut against the side wall of the second positioning rod. When the strong mixer is running, under the impact of dust and air in the strong mixer, the outer arc surface of the curved part of the support ring 3 and the dust fall pipe 2 abuts, and after a period of time, the position of the support ring 3 is adjusted, so that the dust gathered in the upper part of the curved part of the dust fall pipe 2 falls back to the strong mixer.
