Description

Technical Field

[0001] The utility model relates to the field of ship unloader equipment, in particular to a horizontal spiral device of a ship unloader. Background Art

[0002] Ship unloader is a special machine that uses continuous conveying machinery to make a head that can lift bulk materials, or has the ability to take materials by itself, or is equipped with a taking and feeding device to continuously lift bulk materials out of the cabin, and then unload them to the arm or frame and transport them to the shore main conveying system. The use of ship unloader can greatly improve the unloading efficiency, and the minimal dust pollution can keep the environment clean, which is efficient and environmentally friendly.

[0003] However, in a longer-distance material collection process, the lengths of the conveying pipes generally need to be spliced ​​together to achieve stable transportation of materials. However, in the existing structure, in order to ensure its stable rotation, the conveying pipes are generally independent and connected for transportation. The advantage of this is stable transportation, but the equipment cost is relatively high and multiple sets of drive devices are required. Of course, there are also single drive devices, but this structure has the problem of difficult assembly, which affects the transportation efficiency. Utility Model Content

[0004] The main purpose of the utility model is to propose a horizontal spiral device for a ship unloader, aiming to improve the structure of the spiral structure so that each conveying pipeline can be spliced ​​as a single module, but a single drive device or a double-head drive device can be used to achieve stable material transportation, thereby effectively improving the conveying efficiency of long-stroke materials.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a horizontal screw device for a ship unloader, comprising:

[0006] A main pipeline, wherein the main pipeline is provided with an inlet and an outlet, and the main pipeline includes a plurality of branch pipelines and a connection device provided between two branch pipelines;

[0007] The branch pipe is provided with a branch screw shaft, and the connection device comprises a connection pipe matched with the branch pipe and a bearing seat connecting the branch screw shaft;

[0008] The branch pipe at the head end is installed on the motor base, and the branch screw blade shaft at the head end is connected to the rotating device;

[0009] The rear end of the branch pipe at the end is installed on the tail shaft seat;

[0010] The discharge port is arranged on the branch pipe at the head end, and the feed port is arranged on the branch pipe at the tail end.

[0011] In the actual design, the main pipeline is divided into branch pipelines and branch screw blade shafts. At this time, the branch screw blade shaft is generally provided with a support to protect the screw blade from deformation. However, even if it does not support this type of screw blade, the hardness is relatively high. During the actual assembly, the two branch pipelines are spliced ​​together, and then the two branch screw blade shafts are fixed to the bearing seat, thereby realizing the stable rotation of the branch screw blade shaft, and then the connecting pipeline is fixed to the branch pipeline, thereby realizing the splicing and fixation of adjacent branch pipelines, effectively improving the installation efficiency of the spiral device, and in actual work, assuming that the length is not enough, quick disassembly and assembly can be achieved and branch pipelines can be further increased to facilitate long-distance transportation of materials.
