[0022] Further, the conveyor motor 5 drives the transmission roller 4 to drive the scraper 7 to convey the material, at this time, the infrared sensor monitors the material height in the chute in real time, when it is detected that the material accumulation exceeds the preset blocking height, the system automatically triggers the anti-blocking mechanism: the sliding displacement device immediately drives the anti-blocking device to move longitudinally along the chute to the blocking point, the rotating device synchronously adjusts the orientation of the anti-blocking device to accurately aim at the core area of the material accumulation, finally controls the anti-blocking device to perform the rotating crushing operation, forcibly breaks the arching material to restore the flow.

[0023] Please refer to Figure 3 The sliding displacement device comprises fixed rods 8, a connecting rod 9 and a sliding block 10. The fixed rods 8 are provided in two, and each of the two fixed rods 8 is fixedly connected to the front and rear inner walls of the shell 1.

The sliding block 10 is slidingly connected in the sliding groove of the connecting rod 9.

[0024] Further, when the infrared sensor detects that the material in the chute is blocked, the control sliding block 10 is moved transversely along the sliding groove at the lower end of the connecting rod 9, and the anti-blocking device is precisely displaced to the position directly above the blocking point. The movement track of the sliding block 10 is strictly limited in the sliding groove of the connecting rod 9, so as to avoid the deviation or shaking of the unblocking mechanism. Meanwhile, the vibration load during the operation of the conveyor is dispersed to the shell 1 by the two fixed rods 8, so as to ensure the stability of the displacement.

[0026] Further, when the blocking detection device triggers the unblocking instruction, the fourth motor 27 is immediately started and drives the threaded rod 19 to rotate in the interior of the connecting rod 9. At this time, the sliding block 10 is linearly displaced along the sliding groove of the connecting rod 9 under the action of the threaded thrust, so as to drive the anti-blocking device to move to the blocking point coordinate.

[0027] Please refer to Figure 5 and Figure 6 The rotating device comprises a mounting plate 11, a gear one 12, a gear two 13 and a fixed block 14.

Through the meshing transmission between the gear one 12 and the gear two 13, the gear one 12 is reversely rotated at the center of the lower end of the mounting plate 11, so as to drive the fixed block 14 and the anti-blocking device below to realize the 360° precise steering in the horizontal plane, so as to make the axis of the auger bit 18 directly face the core area of the material accumulation.

[0029] Please refer to Figure 5The rotating device further comprises a motor 20 fixedly connected to the upper end of the mounting plate 11, and an output shaft of the motor 20 is fixedly connected to the gear 2 through a rotating shaft.

[0032] Further, when the fixed block 14 positions the anti-blocking device to the point about to be blocked, the rotating plate 15 is fixed to the lower end of the fixed block 14 as a basic bearing frame, and the recess 16 in the interior of the rotating plate 15 provides a rotating space for the rotating block 17. The rotating block 17 is adjusted in pitch ±30° in the recess 16 through a rotating shaft, thereby changing the cutting angle of the spiral drill bit 18. During the unblocking operation, the spiral drill bit 18 is rotated and vertically inserted into the material accumulation body.
