Description

Technical Field

[0001] The utility model relates to the technical field of tube chain conveyors, in particular to a novel turning mechanism for tube chain conveyors. Background Art

[0002] The pipe chain conveyor is a continuous conveying equipment for conveying bulk materials such as powder, small particles and small blocks. It can be conveyed in a horizontal, inclined and vertical combination. It is generally used in fine chemicals, pesticides and minerals, building materials, food industries, etc. In a closed pipeline, the chain is used as a transmission component to drive the material to move along the pipeline. When conveying horizontally, the material particles are thrust by the chain in the direction of movement. When the internal friction between the material layers is greater than the external friction between the material and the pipe wall, the material moves forward with the chain to form a stable material flow; when conveying vertically, the material particles in the pipe are pushed upward by the chain, because the lower feeding prevents the upper material from sliding down, generating lateral pressure, so the internal friction of the material is enhanced. When the internal friction between the materials is greater than the external friction between the material and the inner wall of the pipe and the weight of the material, the material is conveyed upward with the chain to form a continuous material flow.

[0003] After searching, a Chinese patent with publication number CN209777463U discloses a pipe chain conveyor turning mechanism, the technical key points of which are: including a fixed seat and two turning devices fixedly installed on the fixed seat; the turning device includes a box body fixedly installed on the fixed seat, a rotating shaft rotatably arranged in the box body, a sprocket fixedly sleeved on the rotating shaft, and a feed pipe and a discharge pipe fixed on the box body; one end of the feed pipe is connected to the inner cavity of the box body, and a feed joint is provided at the other end of the feed pipe; one end of the discharge pipe is connected to the inner cavity of the box body, and a discharge joint is provided at the other end of the discharge pipe; the two ends of the rotating shaft respectively pass through the left and right ends of the protruding box body, and the protruding end of the rotating shaft is sequentially sleeved with a bearing end cover and a bearing seat. Through the above method, the utility model can be used to solve the situation where the pipe chain conveyor needs to turn in the process of conveying powdery and granular materials; compared with traditional methods such as using elbows, it has the advantages of no friction, low traction, energy saving and easy installation.

[0004] The above solution solves the problem of poor continuity and poor conveying effect when the arc-shaped pipeline is switched, but lacks an adjustment mechanism, which makes it inconvenient to adjust the height of the turning mechanism.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
