Description

Technical Field

[0001] The utility model relates to the technical field of screw conveyors, in particular to a screw shaft connection structure. Background Art

[0002] The screw conveyor is a commonly used material conveying equipment. The screw shaft and the spiral blades are driven by a driving device to rotate, so that the material can be transported along the spiral axis in the pipeline. The screw conveyor has a simple structure, reliable operation, and small footprint. It is widely used in various industrial fields. When the span of the screw shaft is too large, it is necessary to install a connecting structure in the middle position to connect the screw shaft to prevent the screw shaft from deforming due to gravity and wearing the inner wall of the device housing. At present, the existing connection structure usually uses a bearing seat assembly welded to the screw shaft. After long-term use, the bearing will inevitably be affected by dust, resulting in rotation obstruction and wear. Maintenance personnel have to organize the replacement of the connection structure. Because the installation position of the device is narrow, and the screw shaft connection position must be cut, it is time-consuming and laborious, affecting the normal operation of the operation.

[0005] Furthermore, a first connecting hole is radially provided on the bearing rod, and a second connecting hole is provided on the first connecting member and the second connecting member, which is coaxially connected to the first connecting hole and is fixedly connected by a latch.

[0006] Furthermore, the first connecting member is provided with a first connecting groove, and the second connecting member is provided with a second connecting groove that is docked with the first connecting groove and is used for limiting and clamping the bearing rod.

[0007] Preferably, the end of the bearing rod is prismatic, and the first connecting groove and the second connecting groove are connected to form a prismatic hole that matches the end of the bearing rod.

[0008] Furthermore, there is a gap between the first connecting member and the second connecting member and the bearing seat.
