AI Technical Summary
Traditional propeller cutters are ineffective at cutting multiple layers of fishing nets and other debris entangled between the shaft and the hull, especially in confined spaces. This makes it difficult for the cutter blades to reach the core entangled area, affecting the normal operation of the propeller.
A pressure-stabilizing marine propeller-type fishing net cutter mechanism is designed. By adjusting the combination of bolts and oblique cutter heads, the position of the cutter is adjusted, and the relative motion shearing force of the oblique cutter heads is used to cut tangled debris. The oblique cutter head is set on the outside of the cutter to facilitate cutting multi-layered tangled fishing nets.
This design enables the cutter to effectively approach and cut debris such as fishing nets on the outside of the shaft, ensuring the propeller operates normally and preventing debris from getting stuck in the gap between the cutter and the shaft, thus improving cleaning efficiency.
