Description

Technical Field

[0001] This utility model relates to the field of coal chutes, and in particular to an adjustable coal chute that prevents material from deviating from its designated path. Background Technology

[0002] Traditional coal chutes are mostly standardized designs that do not fully consider the throwing curve of the coal flow and the movement trajectory within the chute. The drop between the two-stage conveyors is large, and the coal flow is prone to flowing along the wall due to gravity, making it difficult to align the coal drop center with the center line of the receiving belt. On the other hand, traditional coal chutes often have the design problem of the coal drop center intersecting with the belt center. When the corner difference is small, the material is prone to scouring the opposite side of the baffle. Both of these situations will cause the belt to be unbalanced in terms of material load, which will lead to belt misalignment. Belt misalignment will trigger a series of chain problems and seriously affect production. Utility Model Content

[0034] During operation, the distance and angle between the two baffle plates 622 in each baffle structure 6 can be adjusted using pins 624 to regulate the coal falling position, ensuring the coal flows into the designated location and preventing the conveyor belt below from deviating. Simultaneously, the vibration structure 4 operates continuously during operation, causing the device to vibrate and reducing the possibility of material residue.

[0035] Therefore, this utility model adopts an adjustable material drop point anti-deviation coal drop pipe with the above-mentioned structure. The branch pipe adopts a circular pipe to reduce coal blockage points and prevent coal blockage. In addition, an arc-shaped pipe is used so that the coal flow flows in the direction of belt rotation, reducing the scouring of the lower belt by the coal flow. At the same time, it is combined with a shielding structure. The coal drop position can be adjusted by adjusting the length of the screw so that the coal flow falls into the designated position and prevents the lower belt from deviating.
