Abstract
The utility model provides a debris twisting prevention structure for an outboard engine. The debris twisting prevention structure comprises a screw propeller, a cylinder and a lower box, wherein the lower end of the cylinder is connected with the lower box; an output shaft of the lower box is connected with the screw propeller; a knife blade is arranged behind blades of the screw propeller; the bottom end of the knife blade is arranged on the cylinder or the lower box; a knifepoint faces to the back faces of the blades of the screw propeller; a gap is kept between the knifepoint and the blades; and thus, when debris such as ropes and rattan aquatic plants in a water domain are twisted on the screw propeller, the knife blade can easily cut off the debris to prevent the debris from twisting the screw propeller due to rotation of the screw propeller relative to the knife blade. Therefore, the load of the engine can be effectively reduced, the fuel can be saved, the speed can be increased, and the mechanical failures such as water leakage caused by debris twisting between a shaft of the screw propeller and an oil seal can be avoided.
Description
Technical field
The utility model belongs to Marine outboard motor propeller propulsion system technical field.
Background technology
Existing Marine outboard motor is often run into the careless type of water plant of rope, rattan in the waters etc. in screw propeller rotation progradation, cause screw propeller to hang, and influences power and speed, even damages parts and cause the machine security accident.
Summary of the invention
The utility model provides the anti-strand of a kind of Marine outboard motor foreign material structure to the problems referred to above that prior art exists, and prevents that foreign material from hanging screw propeller, reduces engine loading, saves fuel oil, and raising speed guarantees the safety of using.
The technical scheme of the utility model is following:
The anti-strand of a kind of Marine outboard motor foreign material structure, it comprises screw propeller, cylindrical shell and lower box, the cylindrical shell lower end connects lower box, the output shaft connecting bolt oar of lower box.It is characterized in that: the blade rear at screw propeller is provided with blade; The bottom of said blade is installed on cylindrical shell or the lower box, the vacuum side of blade of point of a knife subtend screw propeller, and keep the gap with blade; Like this when foreign material such as rope, rattan grass type water plant are arranged in the waters are wrapped on the screw propeller; Because screw propeller is rotating with respect to blade, blade just can cut off above foreign material like a cork, avoids it to hang screw propeller.
Further the bottom of blade installs and fixes through screw; The mounting hole of blade is a bar hole, is used to regulate the distance between point of a knife and the propeller blade, like this; Can regulate the gap between point of a knife and the propeller blade according to condition of service, reach the effect of better removing foreign material.
In addition, for the blade of blade, can structure such as sawtooth in the above, can all make or only make single face in the two sides, blade can adopt chevron shaped sword, can make the ability that cuts off of blade stronger like this.
The advantage of the utility model is following:
1, can avoid foreign material to hang screw propeller, effectively reduce engine loading, save fuel oil, raising speed.
2, can effectively avoid between prop shaft and the oil sealing strand to go into foreign material and cause mechanical breakdown such as leak.
Description of drawings
Fig. 1 is the structural representation that the Marine outboard motor of this anti-strand foreign material structure is installed;
Fig. 2 is the structural representation of blade.
The specific embodiment
Referring to Fig. 1, Marine outboard motor is made up of host machine part 5, cylindrical shell 2, lower box 3 and screw propeller 1 etc., and the power of host machine part 5 is connected the output shaft connecting bolt oar 1 of lower box 3 through the power take-off shaft in the cylindrical shell 2 with lower box 3 interior mechanisms.A blade 4 is installed on lower box 3, and blade 4 is locked in the installation screw of lower box 3 through the via hole that attaching screw 6 passes cylindrical shell 2, the vacuum side of blade of the point of a knife subtend screw propeller 1 of blade 4, and keep the gap with blade.
Referring to Fig. 2, the blade of blade 4 adopts chevron shaped sword, on the two sides of blade sawtooth 8 is arranged all, advances, is located at when moveing backward the chevron shaped sword on the blade 4 when ship on-hook 5 drives screw propeller 1, can guarantee actv. cutting foreign material.Mounting hole in the bottom of blade 4 is designed to bar hole 7, is used for regulating point of a knife and screw propeller gap.
