Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for ship unloaders, in particular to a material taking spiral device for ship unloaders. 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 the process of taking finer particles, if the end of the taker is directly inserted into the material, the taker port may cause material accumulation, thereby affecting the cyclic feeding of the taker port, thereby affecting the feeding efficiency. For example, Chinese patent CN201922212657.5 is only applicable to the taker of vertical structure, so the taker still has the problem of empty packages of spiral structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a material taking screw device for a ship unloader, aiming to improve the structure of the existing material taking device, thereby avoiding the accumulation of materials at the material taking port and affecting the material taking efficiency.

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

[0006] A main pipe, wherein the main pipe is a cavity with a material taking channel in the middle, a discharge pipe is provided at the upper end of the main pipe, a loading pipe is provided at the lower end of the main pipe, a discharge port is provided on the side wall of the discharge pipe, and a loading port is provided on the loading pipe;

[0007] A screw blade shaft, wherein a driving seat is provided at the upper part of the feeding tube, the screw blade shaft is provided between the driving seat and the lower wall of the discharging tube, the screw blade shaft is pivotally arranged, and a first spiral blade is provided on the outer peripheral wall of the screw blade shaft;

[0008] A first driving device, which is connected to the screw shaft and can drive the screw shaft to rotate;

[0009] The outer spiral tube is sleeved on the lower part of the main tube, and the upper part of the outer spiral tube is provided with a second driving device for driving the outer spiral tube to rotate. The outer spiral tube is arranged above the feeding port.

[0010] In the actual design, the pipe body of the material taking device is divided into a main pipe, a discharge pipe and a feeding pipe, so that the structure is simpler during installation and design. Although it has more assembly steps, its structure is simpler during production (it can be understood that the feeding port and the discharge port need to be directly set on the main pipe. When the span of the main pipe is larger, the production difficulty increases accordingly). At the same time, a tubular outer spiral pipe is set on the outer periphery of the main pipe, so as to realize the stable rotation of the outer spiral pipe, thereby effectively avoiding the accumulation of materials at the feeding port, causing the problem that the feeding pipe cannot be extended into the material, and effectively ensuring the stable transportation of materials. Through the setting of the feeding pipe, the installation of the outer spiral pipe is also relatively simple, and the structure is relatively stable. BRIEF DESCRIPTION OF THE DRAWINGS

Through the setting of the feeding pipe 12, the installation of the outer spiral pipe 3 is also relatively simple, and the structure is also relatively stable.

[0025] Specifically, the upper end and the lower end of the discharge pipe 11 are connected to the driving seat and the discharge port 101 through the first coupling plate 51 and the second coupling plate 52 respectively, and the side wall of the discharge pipe 11 is provided with the discharge port 101, that is, the installation of the discharge pipe 11 can be completed by using the coupling plate.
