Description

Anti-winding propeller

Technical Field

The utility model relates to a screw technical field, in particular to antiwind screw.

Background

The propeller is a device which rotates in the air or water by means of blades and converts the rotating power of an engine into propulsive force, and can be a propeller with two or more blades connected with a hub, wherein the backward surface of each blade is a spiral surface or a surface similar to the spiral surface. Propellers are widely used, and among them, marine propellers are used as propellers for ships, including propeller hubs and propeller blades.

However, in the prior art, the propeller is inevitably entangled with impurities such as algae and aquatic weeds in water when in use, so that the propeller breaks down, the ship stops running, the maintenance is time-consuming and labor-consuming, and normal travel and transportation activities are affected, so that the propeller structure needs to be improved urgently.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide an antiwind screw, effectively solve the winding problem, simple and practical.

In order to solve the technical problem, the technical scheme of the utility model is that the anti-winding propeller comprises a propeller hub, a plurality of cutters and a plurality of propeller blades, wherein the plurality of propeller blades are fixedly arranged on the outer circumference of the propeller hub along the rotation axis of the propeller hub, the cutters are fixedly arranged on the outer wall of the propeller hub, and the cutters are positioned on one side away from the pushing direction of the propeller blades.

Adopt above-mentioned technical scheme, because the setting of cutter for the screw is at the operation in-process, and the cutter also can rotate thereupon, and then can in time cut off, cut up debris such as algae, pasture and water that are close to the screw to improve the problem of debris winding screw, simple and practical.

Preferably, the number of the cutting knives is three, and the three cutting knives are fixedly arranged on the same circumference along the rotation axis of the propeller hub.

Preferably, three of the cutters are evenly spaced.

Preferably, the diameter of the outer circle formed by the rotation of the propeller blade is smaller than that of the outer circle formed by the rotation of the cutter.

Preferably, the cutter is in the shape of a flat plate, and the cutter is perpendicular to the rotation axis of the propeller hub.

Preferably, the propeller blade edge has a knife edge.

Preferably, the cutter is removably arranged on the propeller hub.

Preferably, the propeller blade and the cutter are made of stainless steel.

Preferably, the propeller hub is made of 45 steel.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1, in a first embodiment, an anti-wind propeller is provided, which includes a propeller hub 1, a plurality of cutting knives 2 and a plurality of propeller blades 3, wherein the plurality of propeller blades 3 are fixedly arranged on the outer circumference of the propeller hub 1 along the rotation axis of the propeller hub 1, the cutting knives 2 are fixedly arranged on the outer wall of the propeller hub 1, and the cutting knives 2 are positioned on the side far away from the pushing direction of the propeller blades 3. Due to the arrangement of the cutter 2, the propeller can rotate along with the cutter 2 in the operation process, so that impurities such as algae and aquatic weeds close to the propeller can be cut off and chopped in time, the problem that the impurities wind the propeller is solved, and the cutter is simple and practical.

Further, in the second embodiment, the number of the cutters 2 is three, and the three cutters 2 are fixedly arranged on the same circumference along the rotation axis of the propeller hub 1. The above arrangement ensures that the cutter 2 has sufficient cutting ability and cutting reliability.

Further, in the third embodiment, three cutters 2 are uniformly spaced. The arrangement can lead the screw propeller to be stressed evenly during operation and is more beautiful.

Further, in the fourth embodiment, the diameter of the outer circumference formed by the rotation of the propeller blade 3 is smaller than the diameter of the outer circumference formed by the rotation of the cutter 2. Above-mentioned setting can more comprehensively intercept and cut the debris such as the algae of smashing and being close to toward propeller blade 3, improve equipment operation's reliability.

Further, in the fifth embodiment, the cutter 2 has a flat plate shape, and the cutter 2 is perpendicular to the rotational axis of the propeller hub 1. The above arrangement can minimize the resistance to rotation of the cutter 2 to reduce the power loss of the engine.

Further, in the sixth embodiment, the propeller blade 3 has a blade edge 31 at its edge. The arrangement enables the propeller blade 3 to cut and crush impurities such as algae, and the winding problem can be further improved.

Further, in the seventh embodiment, the cutter 2 is detachably provided on the propeller hub 1. The cutter 2 can be replaced conveniently by the arrangement, and the cutter is simple and convenient.

Further, in the eighth embodiment, the propeller blade 3 and the cutter 2 are made of stainless steel. The stainless steel is durable, and certainly, in practical application, the propeller blade 3 and the cutter 2 can be made of structural steel, tool steel and the like, but are not limited to the structural steel and the tool steel.

Further, in the ninth embodiment, the propeller hub 1 is made of 45 steel. The 45 steel has high mechanical strength and high wear resistance, but in practical applications, the propeller hub 1 may be made of cast steel, but is not limited thereto.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
