[0026] Working principle:

[0027] When in use, first adjust the size of the feed hopper opening, push the push handle 34 inward, so that the wheel 32 on the side wall of the movable plate 31 rotates along the groove on the inner wall of the shell 1 to drive the movable plate 31 to continuously move toward the dust recovery mechanism 2. When the movable plate 31 continues to move, the return spring 33, which was originally in an unloaded state, is continuously stretched. At this time, the return spring 33 will generate a force to move the movable plate 31 away from the dust recovery mechanism 2. When the movable plate 31 moves, the connecting rod 351 connected thereto will drive the adjustment rod 352 to move, and the adjustment rod 352 will move closer to the dust recovery mechanism 2. When the movable plate 31 moves in the direction of rotation, the clamping head 361 in contact with the groove on its outer wall will continuously swing back and forth around the rotating shaft 365 driven by the groove on the outer wall of the adjusting rod 352. When the movable plate 31 moves to form a feed hopper opening of a suitable size with the inner wall of the shell 1, the pushing of the push handle 34 is stopped. At this time, the rotating shaft 365 is acted upon by the connecting spring 366 to press the clamping head 361 connected to it in the direction close to the adjusting rod 352. At this time, the outer wall of the clamping head 361 and the groove on the outer wall of the adjusting rod 352 are clamped to each other, completing the limitation of the movable plate 31 and ensuring the stability of the size of the feed opening in the subsequent feeding process.

[0028] During the feeding process of flour processing, flour to be processed is continuously put in from the top of the feed hopper, and the built-in motor is turned on to drive the fan blades 23 to rotate. When the fan blades 23 rotate, the flour particles scattered during the feeding process are absorbed into the connecting pipe 24 through the through grooves provided on the side walls of the shell 1, and are concentratedly distributed into the tail pipe 26 through the diversion pipe 25 connected to the connecting pipe 24, and then the collected flour is returned to the feed hopper through the tail pipe 26, thereby reducing the waste of resources caused by the escape of flour during the processing process and preventing the workers from inhaling too much dust to affect their health.

[0029] When the flour processing process is completed, the feed hopper needs to be reset for the next use. When it needs to be reset, first rotate the positioning bolt 353 to make it move continuously in the direction away from the connecting rod 351 until the adjustment rod 352 can rotate around the connecting rod 351. Since the limit pin 364 is constrained by the through groove on the outer wall of the fixed seat 362, the clamping head 361 has an extreme position in contact with the adjustment rod 352. At this time, the adjustment rod 352 is rotated until the groove on the outer wall of the adjustment rod 352 is no longer in contact with the clamping head 361. At this time, the reset spring 33 has the movable When the force of the plate 31 moves away from the dust recovery mechanism 2, the movable plate 31 will continue to move along the groove on the inner wall of the shell 1 in the direction away from the dust recovery mechanism 2 until the reset spring 33 shrinks to the initial state. At this time, the adjusting rod 352 is rotated so that the groove on its outer wall contacts the outer wall of the clamping head 361 again, and then the positioning bolt 353 is rotated to make it continue to approach the direction of the connecting rod 351 until the outer wall of the positioning bolt 353 contacts and tightens the outer wall of the connecting rod 351, thereby completing the fixation of the adjusting rod 352 and preparing for the next use.
