The present invention relates to a snow plow for removing snow accumulated on a road in winter, and more particularly, to a blade protection device of a snow plow that can prevent the blade from being easily worn due to friction with a road surface during snow removal.

Conventional snow plows typically have a blade member having an arc-shaped curved surface at the front for clearing snow.

When the blade member is snow-removed while the blade member is in contact with the ground, or lowered closely, the snow removal vehicle moves to remove snow accumulated on the ground, and when the blade member is moved to another place, the blade member is moved in a lifted state.

However, during the snow removal operation, the lower side of the blade facing the ground hits an obstacle (for example, unevenness or speed bump of the road), or the blade formed of heat-treated steel plate is easily worn by the friction of the road, or the blade member For example, if the blade member falls to the ground due to an operation mistake during the movement, the blade is damaged and, in severe cases, there is a problem that the entire blade must be replaced.

Accordingly, an object of the present invention is to prevent the phenomenon that the blade is worn or partially broken by uneven road and friction by installing and fixing the blade protection member having elasticity at the lower end of the blade member.

The blade protection member is formed of an elastic member such as rubber that retains elasticity, and when the blade contacts an obstacle on the road during operation, the blade protection member is momentarily bent to alleviate the shock transmitted to the blade, thereby damaging the blade. To prevent them.

Hereinafter, with reference to the accompanying drawings, a specific embodiment of the blade protection member according to the present invention will be described in detail the configuration and effect.

1 to 2 are views for explaining the configuration of the present invention, the blade member 10 for pushing the eye; A blade protection device 20 for absorbing shock generated when the blade member comes into contact with an object protruding from the road surface when the blade member is moved; A raising and lowering member (30) for moving in the vertical direction for movement and storage and when using the blade member (10); A rotation angle adjusting member 40 rotating in a left and right direction to send the snow removed by the blade member in a roadside direction; A scattering prevention member (50) which prevents the snow from falling onto the driving unit by overflowing the blade when the snow is removed by the blade member; A mounting member 60 for securely installing the snowthrower including the blade member to the bumper 81 of the vehicle; It consists of a hydraulic drive member connected to the engine to generate the driving force necessary to operate the snowplow including the blade member (10).

The blade member 10 is formed of a blade 11 for removing the snow accumulated on the road by being positioned in front of the lifting and lowering member 30 and the rotation angle adjusting member 40.

In connecting the blade 11, the lower end of the base 14 and the lower end of the blade 11 is connected by a link 12 having a predetermined length, and the tension spring 13 is hung on the lower end of the base 14, When the front end is extended and the fixed piece 11b protruding from the middle of the back surface of the blade 11, the tension of the tension spring 13 retains the blade angle.

And, on the upper surface of the blade member 10 is provided a shatterproof member 50 for preventing the eyes from entering beyond the blade (11).

In addition, a blade protection device 20 is installed at the lower end of the blade member 10 to prevent a phenomenon in which the lower end of the blade 11 is worn or partially broken due to unevenness and friction of the road surface.

The blade protection device 20 forms a hole 11a at the bottom of the blade 11 so that the conventional fastening member 18 is inserted into the hole 16a of the elastic member 16 corresponding to the hole 11a. The elastic member 16 is fixed to the blade 11 by being inserted through.

The scraper 15 is fixed to the other hole 16b of the elastic member 16 installed in the blade 11 so as to be fixed by the fastening element 17 so that the scraper 15 retains the elasticity of the elastic member 16. do.

According to the present invention configured as described above, the bracket 62 of the mounting member 60 is inserted into the bumper of the vehicle so that the bumper and the bracket 62 are connected to each other as a conventional fastening element. The hydraulic driving member is connected to the lifting and lowering member 30 and the rotation angle adjusting member 40 to form a hydraulic circuit.

When the plow is driving the automobile 80 and the hydraulic pressure is provided to the cylinder side of the lifting and lowering member 30 by adjusting the control lever of the hydraulic drive member with the other hand, the blade member 10 is in contact with or close to the road surface. Will be located.

When hydraulic pressure is supplied to the cylinder 41 side of the rotation angle adjusting member 40 by operating the lever of the hydraulic drive member to change the direction of the blade member, the blade member 10 is transverse to the vehicle's forward direction by the extended cylinder. The blade member 10 is placed in a distorted state in one direction.

When the vehicle moves forward in such a state, the scraper 15 of the blade member 10 pushes the snow accumulated on the road surface, and the snow removed from the road surface is pushed in the wrong direction.

When the blade member 10 twisted in one direction is to be returned to the original position, the piston rod returns to its position when the hydraulic pressure supplied to the extended cylinder 41 is provided in the opposite direction. 10) is in a state that lies in the transverse direction with respect to the traveling direction of the vehicle.

As described above, the present invention installs an elastic member that retains elasticity on the blade member, even when an obstacle protruding from the road surface comes into contact with the scraper installed at the end of the blade during operation. By mitigating the shock delivered, it is possible to prevent the blade from being damaged.

If the road obstacle is large, the blade with the elastic member is stretched over the obstacle to prevent the vehicle from overturning.

When the blade member 10 is not used, the blade member 10 is lifted from the road surface by the operation of contracting the length of the cylinder 32 when the supply direction of the hydraulic pressure supplied to the lifting / lowering member 30 is reversed. You are in a losing state.

In such a state that the blade 11 is lifted up, the wear state of the scraper 15 can be confirmed, and at the same time, the replacement work can be performed according to the degree of wear.

As described above, the present invention provides an elastic member having elasticity at the lower end of the blade member assembled to the bumper of the vehicle, which is easy to drive, so that the elastic member 16 is momentarily when the scraper contacts the road surface obstacle during the operation. There is an advantage of preventing damage to the blade by mitigating the impact delivered to the blade is flexed with.

Claims (1)

After the elastic member 16 having a plurality of holes 16a and 16b formed at the top and the bottom thereof, the hole 11a is formed on the bottom surface of the blade 11 so as to correspond to the hole 11a. By inserting and fastening a normal fastening member 18 into the hole 16a of the member 16 and fixing the scraper 15 with the fastening element 17 to the other hole 16b of the elastic member 16, When the obstacle touches, the blade protection device of the snowplow, characterized in that the interruption of the elastic member (16) is bent backward so that the impact is not transmitted to the blade (11).
