[0022] Poking module 4, the poking module 4 includes several rotating rods 41 installed in annular in mounting frame 2, the rotating rod 41 is rotatably installed on mounting frame 2, and reset torsion spring is also provided between the rotating rod 41 and mounting frame 2, several poking rods 42 are distributed equidistantly on the rotating rod 41, the end of each rotating rod 41 is equipped with adjusting gear 45, and mounting ring 43 is fixedly installed at corresponding position on the rack 1, and several tooth sections 44 are arranged in annular on the inner wall of mounting ring 43.

[0023] In the embodiment of the utility model, four rotating rods 41 are arranged. In use, a screening cylinder is formed by the cooperation of the mounting frame 2 and the arc-shaped screening plate 21, slag enters the interior from one end of the screening cylinder, and then is discharged from the other end. When screening is to be performed, the driving module 3 is only needed to be started, the mounting frame 2 is driven to rotate by the driving module 3, and thus the slag is screened through the screening holes on the arc-shaped screening plate 21. Meanwhile, in the working process, the mounting frame 2 drives the rotating rods 41 to rotate synchronously with the axis of the arc-shaped screening plate 21 as the center, in this process, the adjusting gears 45 at the ends of the rotating rods 41 will intermittently contact the toothed segments 44 on the inner wall of the mounting ring 43. In the process of engagement between the adjusting gears 45 and the toothed segments 44, the rotating rods 41 will rotate with their own axes as the center, after the adjusting gears 45 and the toothed segments 44 are disengaged, the rotating rods 41 will return to the initial state under the action of the reset torsional springs, thus the periodic swinging of the rotating rods 41 is realized, the raking rods 42 on the rotating rods 41 are driven to swing synchronously, and thus the slag in the screening cylinder is raked, and the screening of the slag is accelerated.

[0024] As shown in Figure 1 As a preferred embodiment of the utility model, the driving module 3 comprises a driving motor 31 mounted on the rack 1 and a transmission gear ring 33 mounted on the mounting frame 2, the output end of the driving motor 31 is connected with a gear transmission set 32, and the gear transmission set 32 is connected with the transmission gear ring 33.

[0025] In the embodiment of the utility model, in use, the driving motor 31 is only needed to be started, the driving motor 31 can realize the power output of the transmission gear ring 33 through the gear transmission set 32, and thus the mounting frame 2 is driven to rotate synchronously through the transmission gear ring 33.

[0026] As shown in Figure 1 and 2 As a preferred embodiment of the utility model, the arc-shaped screening plate 21 is detachably mounted on the mounting frame 2, and the arc-shaped screening plate 21 is provided in multiple specifications, the hole diameters of the screening holes on the arc-shaped screening plates 21 of different specifications are different, and the hole diameters of the screening holes on the same arc-shaped screening plate 21 are the same.

[0027] In the embodiment of the utility model, the arc-shaped screening plate 21 is mounted on the mounting frame 2 in the mode of bolt connection, and is mounted in a detachable mode, so that the arc-shaped screening plate 21 can be conveniently replaced. Compared with the integral structure of the traditional screening cylinder, when the arc-shaped screening plate 21 is damaged, only the specified arc-shaped screening plate 21 needs to be replaced, and the entire screening cylinder does not need to be replaced. Moreover, different arc-shaped screening plates 21 with different hole diameters can be replaced according to the use requirement, so that the screening effect of the device can be flexibly adjusted.

[0028] As a preferred embodiment of the utility model, the rotating rod 41 can be installed on the mounting frame 2 in a fixed connection mode, that is, without setting the adjusting gear 45 and the tooth segment 44. In this state, the rotating rod 41 only rotates synchronously with the screening drum, thereby driving the rotating rod 41 to stir the material.

When screening is to be performed, the driving module 3 is only started, the mounting frame 2 is driven to rotate through the driving module 3, thereby the slag is screened through the screening holes on the arc-shaped screening plate 21. At the same time, in the working process, the mounting frame 2 drives the rotating rods 41 to rotate synchronously with the axis of the arc-shaped screening plate 21 as the rotation center, in this process, the adjusting gears 45 at the ends of the rotating rods 41 will intermittently contact the tooth segments 44 on the inner wall of the mounting ring 43. In the process of engagement of the adjusting gears 45 and the tooth segments 44, the rotating rod 41 will rotate with its own axis as the rotation center, when the adjusting gears 45 and the tooth segments 44 are disengaged, the rotating rod 41 will restore the initial state under the action of the reset torsional spring, thereby realizing the periodic swing of the rotating rod 41, the stirring rods 42 on the rotating rod 41 swing synchronously, thereby the slag in the screening drum is stirred, and the screening of the slag is accelerated.
