Description

Technical Field

[0001] The utility model belongs to the technical field of spiral blades, and in particular relates to a spiral blade for a spiral ship unloader. Background Art

[0002] The screw ship unloader is a ship unloading machine with a horizontal screw conveyor without flexible traction components, a vertical screw conveyor and a special material-retrieving device as the main working mechanism. It is a high-efficiency continuous bulk cargo ship unloader. The screw ship unloader is in use, and the core component is the internal spiral blade structure. The spiral blade is driven to rotate by the screw rod to achieve feeding.

[0003] The existing spiral blades for spiral ship unloaders are installed on the cylinder in a spiral array type, and the cylinder drives the blades to rotate to achieve material conveying. However, there are the following defects: (1) When assembling the existing spiral blades, they are placed on a base used for assembling the cylinder and the spiral array of blades. When placing them, the protrusions on the base are stuck in the grooves of the blades to achieve assembly alignment, and then they are fastened and installed with a bolt assembly. However, during the actual assembly process, since the bolt assembly is composed of a nut and a stud, a tool is required to clamp and align the two structures, and then repeatedly screw them, resulting in inconvenient assembly and disassembly and time-consuming and labor-intensive problems. For this reason, we propose a spiral blade for a spiral ship unloader. Utility Model Content

[0004] The utility model aims to provide a spiral blade for a spiral ship unloader, so as to solve the problem that the spiral blade for a spiral ship unloader proposed in the above background technology is inconvenient, time-consuming and labor-intensive to disassemble and assemble because it is fixed with bolt assemblies.

[0006] Preferably, a blocking hole is opened on the surface of the locking block, a blocking block is arranged inside the blocking hole, and the blocking block is fixed on the inner wall of the assembling groove.

[0007] Preferably, the cross section of the lock column is a T-shaped structure, and the longitudinal section of the lock column is a circular structure.

[0008] Preferably, the end surface of the locking cylinder is provided with a bevel.

[0009] Preferably, a ball groove is provided on the surface of the locking block, and a ball is embedded in the ball groove.

[0010] Preferably, a guide column is arranged on the inner side of the spring, a guide cylinder is sleeved on the outer wall of the guide column, the guide cylinder is fixed on the inner wall of the assembling groove, and the guide column is fixed on the surface of the locking block.

[0011] Preferably, the cross-sections of the guide column and the guide cylinder are both circular structures, and the central axes of the guide column and the guide cylinder coincide with each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) Through the designed lock column, lock block, spring and assembly groove, when the blade body is assembled on the base, the blade body is placed on the base, and the protrusion on the base is stuck in the groove on the surface of the blade body to achieve assembly alignment. When the lock column is inserted into the base and the blade body, the inclined surface of the lock block is squeezed and pushed to slide into the assembly groove to avoid it. The lock column completely penetrates the blade body and the base. The spring in a compressed state exerts an elastic force on the lock block, so that one end of the lock block pops out of the assembly groove and the other end blocks it. The stopper is placed at the end of the base to realize quick assembly of the blade body. At the same time, when disassembling, the locking block is squeezed to make it slide into the assembly groove to avoid it, and the locking column can be pulled out, so that the utility model is convenient for disassembly and assembly, saving time and effort. The designed stopper and stop hole are used to limit the locking block to prevent it from falling off from the assembly groove. The designed ball bearing has a lubricating effect to reduce the influence of friction resistance on the surface and contact surface of the locking block. The designed guide tube and guide column are used to support and correct the spring to prevent the spring position from changing and the locking block from losing its elastic effect.
