A bearing seat 29 is mounted on the fixed seat 3 to establish a rotational connection relationship between the main lever 261 and the fixed seat 3.
Through the structure, a user can adjust the position of the sensor 23 according to the needs, so that the sensor 23 can achieve a good detection effect. When the position of the sensor 23 needs to be adjusted, the specific operation modes are as follows: the locking handle 28 is rotated upwards, so that the locking handle 28 is separated from the guide sleeve 27; then, the adjustment handle 26 is turned to adjust the component support 22 upward or downward; finally, after the adjustment is completed, the locking handle 28 is turned to abut against the upper end of the guide sleeve 27. It can be seen that by providing the positioning fixing shaft 24, when the position of the component support 22 is adjusted, the sliding guiding action between the positioning fixing shaft 24 and the guiding sleeve 27 can make the component support 22 always parallel to the rotation axis of the cylindrical screen 1, and after the adjustment is completed, the position of the positioning fixing shaft 24 is locked by the locking handle 28, so that the component support 22 can be prevented from shaking when the screening device is operated.

When the screening device executes screening operation, the material to be screened is filled in the cylindrical screen body 1, when the cylindrical screen body 1 rotates, the material is lifted along with the rotation of the cylindrical screen body 1 due to the friction force between the material and the inner wall of the cylinder, and moves towards the high side of the guide plate 51 when the material is lifted, after the material is lifted to the extreme position, the material is separated from the cylindrical screen body 1 and falls off, and the extreme position to which the material can be lifted is higher than the high side of the cylindrical screen body 1, so that the material is supported by the guide plate 51 after falling off and slides to the low side of the guide plate 51 along the guide plate 51, and falls back into the cylindrical screen body 1 from the low side. The guide plate 51 passes through the rotation axis of the cylindrical screen 1 or is located above the rotation axis of the cylindrical screen 1, so that about half of the screen surface of the cylindrical screen 1 can be used (as shown in fig. 3). In contrast, if the guide plate 51 is not provided, the material falls down after being lifted to the extreme position or rolls down to the bottom of the cylindrical screen 1 along with other materials and then performs the next screening, the screening surface utilization rate is only 1/4-1/3 (as shown in fig. 6), so that the screening efficiency is greatly reduced, the material gathers in the cylindrical screen 1 and the blocking probability is increased, and the above problems are avoided by adding the guide plate 51 in the scheme of the invention.
The angle of the guide plate 51 relative to the fixed base 3 can be adjusted. The user can adjust the angle of the guide plate 51 according to the limit position that the material can reach along with the cylindrical screen body 1, so that the high side of the guide plate 51 is lower than the limit position to ensure the screening effect.

Preferably, as shown in fig. 7, the pneumatic spray valve 21 is rotatably mounted on the spray valve bracket 210, the spray valve bracket 210 is fixedly mounted relative to the fixing seat 3, and the block-removing component 2 further includes two driving rods 220, wherein one driving rod 220 is in a rotational connection relationship with the odd-numbered pneumatic spray valves 21, and the other driving rod 220 is in a rotational connection relationship with the odd-numbered pneumatic spray valves 21; each drive rod 220 is independently translatable relative to the valve carriage 210 to rotate the pneumatic valve 21 coupled thereto relative to the valve carriage 210. Through the above structure, when the sensor 23 detects that the air pressure spray valve 21 cannot meet the blocking clearing requirement, the working mode of the switchable air pressure spray valve 21 is changed into the cross auxiliary working mode, so that the two driving rods 220 move in turn. When the driving rod 220 connected with the even-numbered air pressure spray valves 21 moves, the even-numbered air pressure spray valves 21 rotate to align with the action points (shown in fig. 8) of the adjacent air pressure spray valves 21, and after a set time is maintained, the driving rod 220 resets the even-numbered air pressure spray valves 21; similarly, when the driving rod 220 connected to the odd-numbered air pressure spraying valve 21 moves, the odd-numbered air pressure spraying valve 21 rotates to align with the action point of the adjacent air pressure spraying valve 21 and maintain the set time, and then the driving rod 220 resets the odd-numbered air pressure spraying valve 21. Thus, the air flow intensity of each cleaning point can be doubled by the aid of the adjacent air pressure spray valve 21, and the cleaning force is effectively improved.
