Abstract
Description
The present invention relates to a snowplow having blades, and more particularly, to a snowplow having a lifting movement and left and right rollable blades in which continuous snow removal operations can be continued without a separate operation of the driver even when the road surface is inclined or dents.
In general, a snow removal vehicle (for example, a tractor) provided with blades is used for road snow removal. The snow removing vehicle can adjust the direction of the blade. Therefore, the snow removal vehicle removes snow from the road quickly while simultaneously performing snow removal and topdressing using a blade.
In this process of snow removal, the blade is controlled by the operator appropriately to the condition of the road surface. However, there is a situation where it is difficult to control the direction and attitude of the blade by the operator. For example, it is difficult to change the direction and attitude of the blade in the case where the road surface is inclined in one of the width directions or suddenly dents.
As a background technology of the present invention, a 'snow plow buffer' is proposed as Korean Patent Registration No. 10-0369931. It is attached to the mounting plate formed on the front of the large truck to remove the snow accumulated on the road, and has a predetermined width and size, the upper and lower body rear is provided with a connecting portion provided with a hinge groove, the upper end A fastener is formed in the center part, and the intermittent plate is located at both sides of the snow removal plate, and the rear side of the snow removal plate is positioned at a predetermined interval, and the mounting portion having a rotation groove on the front and bottom of the body is provided. The lower portion of the body is formed with a latch, the main frame is installed in conjunction with the mounting plate, and the hinge portion of the mounting portion of the main frame and the snow plate is arranged in the hinge axis, so as to selectively vary the angle of the snow plate, An angle adjusting bar, a fixing tool of the snow removing plate, and a locking spring of the main frame, and a restoring spring for controlling the operation of a selectively changing snow removing plate, and a lower portion of the main frame. Formed on the side mainframe, located between the guide plate fixed to the rear side of the snow removing plate in the vertical direction and at the bottom of the intermittent plate, and is provided with a stopper for controlling excessive upward displacement of the snow removing plate, the projection of the road during work When the snow removal plate and the contact, the shock is buffered while varying the angle of the snow removal plate by the elastic force and the restoring force of the angle adjustment bar formed on the rear side of the snow removal plate and the restoring spring.
However, the background art suggests a method of cushioning a shock by raising a snow removing plate, and a technique for controlling a posture or a direction of a blade at a slope or a depression of a road surface is not proposed. As a result, the work ability of snow removal is reduced and the efficiency is reduced.
The present invention was devised in view of the above circumstances, and even when the road surface is inclined or dents, the attitude and direction of the blade are automatically corrected so that the lifting and moving can be continued without snowman's separate operation. Its purpose is to provide a snow plow with blades which can be rolled left and right.
Snow plow having a lifting movement and left and right rollable blades according to an embodiment of the present invention,
A blade support frame detachably connected to the boom device of the vehicle and having a pivot arm projecting at the front center; In a snowplow having a blade pivotally connected to a blade support frame, the left and right angles of which are controlled by a clay cylinder,
A pivot bracket installed at the rear rear center of the blade;
A pin bushing installed in the pivot arm of the blade support frame in a hollow form;
A pivot pin inserted in the pin bushing and connected to the pivot bracket;
The top cover cylinder is connected to both ends of the spherical and at the same time the hollow cross section of the pin bushing is larger than the cross section of the pivot pin is characterized in that the left and right rolling of the blade by the rolling gap formed between the pin bushing and the pivot pin. .
In addition, the pin bushing and the pivot pin is characterized in that both are assembled with a circular cross section.
In addition, the pin bushing has an elliptical cross section and the pivot pin has a circular cross section.
In addition, the length of the pin bushing is configured to be smaller than the length of the pivot pin so that the blade is moved up and down relative to the blade support frame, characterized in that it has a constant lifting stroke between the pivot arm and the pivot bracket.
According to the snowplow having the lifting movement and left and right rollable blade of the present invention, when the road surface is inclined to either side, the pivot pin can be inclined so that the blade of the blade is rolled by the inclination along the inclined road surface to separate the driver. Close contact without operation improves snow removal ability.
In addition, since the blade side pivot pin descends from the support frame side pin bushing in the depression, the snow blade of the blade reaches the recessed bottom surface, so that snow removal is continued without the operator's separate operation, thereby improving snow removal efficiency.
The following drawings, which are attached in this specification, illustrate the preferred embodiments of the present invention, and together with the detailed description thereof, serve to further understand the technical spirit of the present invention. It should not be construed as limited.
