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 with low maintenance cost. 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 reclaiming device as its main working mechanism. It is a high-efficiency continuous bulk cargo ship unloader. The core component of the screw ship unloader is the internal spiral blade structure, which is driven by the screw rod to rotate the spiral blade to achieve feeding.

[0003] The existing spiral blades for spiral ship unloaders are driven to rotate by the spiral rod during use, so that the spiral blades can transport materials. However, there are the following defects: (1) The existing spiral blades for spiral ship unloaders are easily damaged during use. When local damage occurs, the entire spiral blade needs to be removed from the spiral rod for overall replacement and maintenance, resulting in a high maintenance cost for the spiral blades. Therefore, we propose a spiral blade for spiral ship unloader with low maintenance cost. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) The traditional spiral blade body is split into multiple spiral single-piece structures by designing multiple spiral single pieces, docking grooves, docking plates, assembly cylinders, movable sleeves, locking pins and connecting rods. The docking plates of the spiral single pieces are inserted into adjacent docking grooves, and then the locking pins are inserted into the locking holes to achieve splicing. When the spiral blade body is partially damaged, the movable sleeve is pulled to drive the locking pin to move through the connecting rod in the movable sleeve, so that the locking pin is separated and unlocked from the locking hole, so that the damaged part of the spiral single piece can be disassembled from the whole spiral blade body, and the local blade can be replaced. When the model is damaged, there is no need to replace the entire part, only the corresponding position needs to be disassembled and replaced, which reduces the maintenance cost of the spiral blade. Through the designed spring, the spring exerts elastic squeezing action on the lock column, so that the lock column is firmly inserted in the lock hole and is not easy to separate. Through the designed inner groove and rubber ring, the rubber ring is set in the gap between the movable sleeve and the assembly cylinder, which has a sealing effect to prevent foreign matter from being stuck in the gap and affecting the activity of the movable sleeve. Through the designed magnetic sleeve, the magnetic sleeve produces an adsorption effect on the side wall of the lock column in the lock hole, so as to further adsorb and fix the lock column, thereby improving the connection firmness of the utility model.
