Description

Technical Field

[0001] The utility model relates to the field of ship unloader equipment, in particular to a middle vertical 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] When transporting some materials with heavy loads or certain temperatures, when the speed of the screw shaft is too high, the screw shaft and the bearing will often have overheating and eccentricity problems, which will cause friction between the screw blades and the inner wall of the conveying pipe, thus affecting the working stability. Therefore, after working for a period of time, the screw shaft needs to be stopped and cooled to reduce the eccentricity caused by wear and tear, thereby protecting the screw device. Utility Model Content

[0004] The main purpose of the utility model is to propose a middle vertical screw device of a ship unloader, aiming to design a bearing with a cooling structure, thereby reducing the heat generated when the screw shaft rotates at high speed or under load, thereby making the screw shaft rotate stably while protecting the material conveying equipment.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a middle vertical spiral device of 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 bearing seat comprises an upper shaft seat installed on the connecting pipe and a lower shaft seat installed on the upper shaft seat, wherein the upper shaft seat and the lower shaft seat form a pivot hole arranged along the axis, and the front and rear ends of the pivot hole are provided with stoppers, and form a limit groove;

[0009] The shaft center is pivotally mounted in the pivot hole, and the shaft center is provided with a limiting portion that is inserted into the limiting groove, the limiting portion and the limiting groove form a flow channel, and a relatively sealed cavity is formed by the blocking portion, and the two ends of the shaft center are used to connect the two branched spiral blade shafts;

[0010] The upper shaft seat and the lower shaft seat are respectively provided with an input pipe and an output pipe communicating with the cavity, and the input pipe and the output pipe are fixed between the bearing seat and the connecting pipe.

[0011] In the actual design, the spiral material conveying device is arranged vertically, so the rotational lubrication requirements for the branch screw blade shaft are relatively high. The upper shaft seat and the lower shaft seat are cooperated to facilitate the installation of the axis, wherein the axis is used to facilitate the mutual splicing of the branch screw blade shafts. During assembly, the axis is installed on the upper shaft seat, and then the lower shaft seat is fixed to limit the axis and form a sealed cavity. The circulation of the lubricating oil is realized by connecting the input pipe and the output pipe, thereby effectively improving the rotational stability of the branch screw blade shaft.
