Abstract
The utility model relates to the technical field of ship power driving devices, in particular to a propeller capable of cutting automatically. The propeller comprises a propeller body, a transmission shaft and a ship stern tube or a tail shaft bracket and is characterized in that the propeller is provided with a sawtooth-shaped cutting tool, the sawtooth-shaped cutter tool is arranged on a rear end face of the propeller, a blade of the sawtooth-shaped cutting tool faces towards the ship stern tube or the tail shaft bracket, and the blade of the sawtooth-shaped cutting tool is in a herringbone shape and used for cutting thick and touch fishing nets and ropes. The propeller can rotate to automatically cut entanglement, has the advantages of being simple in structure, complete in cutting, high in work efficiency and the like, can be widely applied to various ships and can avoid faults caused by entanglement.
Description
Technical field
The utility model relates to the Power Drive Unit technical field of boats and ships, specifically a kind of screw propeller with surface trimming.
Background technology
As everyone knows, the propelling unit of boats and ships generally adopts the screw propeller mode, screw propeller is comprised 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 the navigation that screw propeller rotates to drive boats and ships, during navigation, groove between screw propeller oar drum and ship stern pipe or beauty's frame and the screw propeller oar drum is usually by the floating debris in the water, fishing net, the windings such as hawser, affect the normal operation of screw propeller, sometimes also can cause damaging screw propeller, boats and ships run out of steam, and 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 installed on the outer wall of ship stern pipe or beauty's frame and stride across the 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 installed on the outer wall of ship stern pipe or beauty's frame along the direction with 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 twine parcel with cutter, affect the normal operation of screw propeller, sometimes also can cause boats and ships to run out of steam, cause a serious accident.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of screw propeller with surface trimming of simple in structure, easy to process, good cutting effect is provided.
The utility model can reach by following measure:
A kind of screw propeller with surface trimming, comprise screw propeller, transmission shaft and ship stern pipe or beauty's frame, it is characterized in that being provided with the serration cutting tool, the serration cutting tool is installed on the 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 described in the utility model is " people " font, fishing net and the rope of, good toughness thick to cut.
The utility model utilizes the rotational automatic of screw propeller that twister is cut, and it has simple in structure, cutting thoroughly, the advantage such as screw propeller work efficiency height, can be applicable to various boats and ships, be wound and the fault that causes by screw propeller preventing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, a kind of screw propeller with surface trimming, 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 give unnecessary details, of the present utility model being characterised in that is provided with serration cutting tool 4, serration cutting tool 4 is installed 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 utility model utilizes the rotational automatic of screw propeller that twister is cut, and it has simple in structure, and cutting thoroughly, the advantages such as screw propeller work efficiency height, can be applicable to various boats and ships, be wound and the fault that causes by screw propeller preventing.
