Abstract
The invention relates to the technical field of a power drive device of boats and ships, and concretely relates to a propeller with an automatic cutting device. The propeller with the automatic cutting device comprises the propeller, a transmission shaft and a stern tube or a bracket of the boats and ships. The propeller with the automatic cutting device is characterized in that a zigzag cutting cutter is arranged and mounted on the rear end face of the propeller, the cutting edge of the zigzag cutting cutter faces to the stern tube or the bracket of the boats and ships, and the cutting edge of the zigzag cutting cutter is in the shape like a reversed V in order to cut thick fishing nets and ropes with good tenacity. The rotation of the propeller is used for automatically cutting entanglements. The propeller has the advantages that the structure of the propeller is simple, cutting is thorough, the working efficiency of the propeller is high and the like. The propeller can be applied to all kinds of boats and ships to prevent failure caused by that the propeller is twined.
Description
Technical field
The present invention relates to the Power Drive Unit technical field of boats and ships, specifically a kind of screw propeller with automatic cutting device.
Background technology
As everyone knows, the propelling unit of boats and ships generally adopts screw propeller mode, screw propeller is made up of oar drum and screw blade, screw propeller is connected with the output shaft of engine through transmission shaft, transmission shaft is through bearing, bearing seat is connected with hull with sealing arrangement, the corresponding screw propeller of hull junction is provided with ship stern pipe or beauty's frame, transmission shaft drives screw propeller to rotate to drive the navigation of boats and ships, when navigation, groove between screw propeller oar drum and ship stern pipe or beauty's frame and screw propeller oar drum is usually by the floating debris in water, fishing net, the windings such as hawser, affect the normal work of screw propeller, sometimes also can cause damaging screw propeller, boats and ships run out of steam, cause a serious accident.
Chinese patent calls 008100483533 to disclose " a kind of auto cutting device for twister of propeller ", it comprises cutting tool, it is characterized in that described cutting tool be arranged on the outer wall of ship stern pipe or beauty's frame and stride across ship stern pipe or beauty's frame and screw propeller oar drum between groove, end face and the lateral surface of described cutting tool screw propeller are provided with blade, cutter is along being arranged on the outer wall of ship stern pipe or beauty's frame with the direction of ship stern pipe or beauty's frame axially parallel, its deficiency is that inconvenience is installed, result of use is poor, sometimes floating debris, fishing net and hawser etc. can be wound around parcel by cutter, affect the normal work of screw propeller, sometimes also can cause boats and ships to run out of steam, cause a serious accident.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of screw propeller with automatic cutting device of simple in structure, easy to process, good cutting effect is provided.
The present invention can reach by following measure:
A kind of screw propeller with automatic cutting device, comprise screw propeller, transmission shaft and ship stern pipe or beauty's frame, it is characterized in that being provided with serration cutting tool, serration cutting tool is arranged on screw propeller aft end face, and the blade of serration cutting tool is towards ship stern pipe or beauty's frame.
The blade of serration cutting tool of the present invention is " people " font, fishing net and the rope of, good toughness thick to cut.
The present invention utilizes the rotational automatic of screw propeller to cut twister, and it has simple in structure, cutting thoroughly, screw propeller work efficiency advantages of higher, can be applicable to various boats and ships, be wound and the fault that causes by screw propeller preventing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of screw propeller with automatic cutting device, comprise screw propeller 1, transmission shaft 2 and ship stern pipe or beauty's frame 3, the structure of above-mentioned each component part and the interconnected relationship between them are same as the prior art, this does not repeat, the invention is characterized in and be provided with serration cutting tool 4, serration cutting tool 4 is arranged on screw propeller 1 aft end face, the blade of serration cutting tool 4 is towards ship stern pipe or beauty's frame 3, the blade of described serration cutting tool 4 is " people " font, thick to cut, the fishing net of good toughness and rope, the present invention utilizes the rotational automatic of screw propeller to cut twister, it has simple in structure, cutting thoroughly, screw propeller work efficiency advantages of higher, can be applicable to various boats and ships, be wound and the fault that causes by screw propeller preventing.
