[0026] During specific implementation, the rolling vibration screening machine with a material guiding structure can start the transmission motor 8 in the mounting shell 7 when dust reduction is needed. The rotation of the transmission motor 8 will drive the bevel gear set 9 to rotate. The bevel gear set 9 is composed of three bevel gears meshing with each other. One bevel gear is connected to the output shaft of the transmission motor 8 and lacks some teeth. The other two bevel gears are connected to the outside of the rotating shaft 10. When the transmission motor 8 drives the bevel gears therein to rotate, the rotating shaft 10 will rotate with the cooperation of the bevel gears. At the same time, since one of the bevel gears lacks some teeth, when the position lacking the teeth rotates to the position of the bevel gear on the left, the bevel gear on the right will drive the rotating shaft 10 to rotate. Conversely, when the position lacking the teeth rotates When it reaches the position of the bevel gear on the right, the bevel gear on the left will drive the rotating shaft 10 to rotate in the opposite direction, so that the driving gear 11 connected to one end of the rotating shaft 10 rotates forward and reverse, and the bottom of the driving gear 11 is meshed with the rack 12. At this time, when the driving gear 11 rotates, it will drive the rack 12 to slide, and at the same time, the rack 12 will continuously slide back and forth, and drive the movable frame 13 on one side of the rack 12 to move, and the movable frame 13 will drive the top through-connected nozzle 14 to move. At this time, start the water pump 16, and through the cooperation of the hose 15 and the water pump 16, water can be sprayed out from the nozzle 14, thereby playing a role in dust reduction and preventing the surrounding environment from being affected during material screening.

[0028] A fixing frame 18 is installed on the inner wall of the outer shell 1, a positioning rod 19 is installed between the two groups of fixing frames 18, a driven shaft 20 is installed inside the two groups of fixing frames 18, a transmission belt 21 is connected between the two groups of driven shafts 20 through a pulley, a transmission gear set 22 is connected in the middle of one group of driven shafts 20, a connecting shaft 23 is connected in the middle of the transmission gear set 22, a worm gear 24 is installed on the outside of the connecting shaft 23, a worm 25 that passes through the outer shell 1 and the fixing frame 18 is connected to the top of the worm gear 24, a baffle 26 is installed at the bottom of the connecting shaft 23 and a group of the driven shafts 20, and the baffle 26 forms a rotating structure through the connecting shaft 23 and the fixing frame 18.

[0029] In specific implementation, the rolling vibration screening machine with a material guiding structure can rotate the worm 25 when it is necessary to guide the material. Since the worm 25 is connected to the worm wheel 24, the worm wheel 24 will rotate at this time, and the worm wheel 24 is connected to the connecting shaft 23. At this time, the connecting shaft 23 will drive the baffle 26 at the bottom to rotate. At the same time, the connecting shaft 23 and a group of driven shafts 20 are connected to each other through a transmission gear set 22. The transmission gear set 22 is composed of two mutually meshing transmission gears, one transmission gear is connected to the driven shaft 20, and the other transmission gear is connected to the driven shaft 20. The wheel is connected to the connecting shaft 23, and the driven shaft 20 will be rotated through the transmission gear set 22. The two sets of driven shafts 20 are connected to the transmission belt 21 through the pulley. The driven shaft 20 on the other side will be driven to rotate through the transmission belt 21, and the baffle connected to the bottom of one set of driven shafts 20 will rotate in the opposite direction. At this time, the angles of the two sets of baffles can be adjusted so that the two sets of baffles rotate closer to or away from each other. By changing the angle of the baffle, the material can be better guided to avoid splashing of the material.

[0030] See also Figure 2 , Figure 3 and Figure 4 It can be seen that when in use, the angle of the baffle can be adjusted through the driven shaft 20 and the connecting shaft 23, so as to avoid the phenomenon of waste caused by random splashing of materials.
