JPH07317037A - Rotary ice breaker by use of pressure difference on frozen road - Google Patents

Abstract

PURPOSE:To prevent a pavement from being damaged, by providing a rotary body with the wave-formed rugged inside and a plurality of claws at the outside. CONSTITUTION:An ice breaker rotating by making use of the pressure difference is fixed at a post provided at the front side of a snow-removal device to advance while breaking thick ice on a road. When one of claws of the ice breaker advances while breaking ice and it is caught by obstacles like pavements, balls 2 positioned at the wave-form rugged bottom 5 is transferred to the wave-form rugged top 6 while pushing springs 3 to the center, by the rotary force of the rotary body 7 and the balls are transferred from the top 6 to the next bottom 5 and at the same time, the next claw 1 of the rotary body 7 is fed. In this way, when ice on a frozen road is cut by the ice breaker, since the claw 1 is rotated by the pressure, damage of pavement can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for scraping off ice on a road, and an ice-breaking device on a frozen road which is rotated to prevent damage to the pavement when an excessive force is applied.

[0002]

2. Description of the Related Art To shave off ice on a conventional frozen road,
Comb tooth rake type is known

[0003]

The conventional rake type ice crushing device has a problem that the pavement surface is also scraped because the ice is pressed to scrape the ice.

An object of the present invention is to, when a claw for shaving ice is caught on the way, rotate the claw without forcibly pressing it and shave the ice with the next claw.

[0005]

In order to achieve the above object, in the ice-breaking device on a frozen road according to the present invention, the ball is pulled in and rotated by utilizing the force applied when the claw is caught on the way. The next nail appears on the road

The force applied causes the sphere to move toward the center point,
And the rotating body sends out the next claw

In addition, in order to adjust the strength of the upper and lower sides of the ball, the spring is strengthened by tightening the screw facing the ball from the center point.

Also, loosen the screw to weaken the spring.

Further, the smooth wavy unevenness and the sphere cause the claws to rotate sequentially due to the pressure.

[0010]

When the ice-breaking device on the frozen road constructed as described above is used to scrape off the ice on the road, the pawls are rotated by the pressure, so that the pavement is not damaged.

[0011]

EXAMPLES Examples will be described with reference to the drawings. In FIGS. 1 to 3, pressure snow and ice claws on frozen roads (1)
It is a device to scrape off with

At this time, when the pavement under the ice is nailed,
Claws try to rotate due to changes in pressure so that the pavement is not damaged

The sphere (2) is pushed toward the center point by the action of the wavy unevenness (5, 6), the rotating body (7) rotates, and the next claw reaches the road surface.

The claw of the rotating body (7) moves while crushing ice, but rotates when it is caught on asphalt.

To rotate this rotating body, the strength of the spring is determined by adjusting the screw (4).

The device is assembled with the tightening bolt (11) and the nut (12), and is fixed to the column by the mounting bolt (14).

In FIGS. 4 and 5, the strength of the rotation of the rotating body (7) is adjusted by the screw (4) from the outside (17) while the device is attached to the column.

The spring (3) for pushing up the ball (2) pushes up one side of the hinge (16) with the screw (4) so that the one directly connected to the hinge pushes up the spring.

[0019]

Since the present invention is configured as described above, it has the following effects.

By attaching an ice-breaking device that rotates by utilizing a pressure difference to a column provided in front of the snow blower, the ice breaker moves forward while crushing thick ice on the road.

When one of the plurality of claws of the ice crushing device moves forward while crushing ice, when the claw is caught by an obstacle such as pavement, the pressure causes the claw to rotate, and the next claw moves forward while crushing ice on the road. To do.

For that purpose, the spring is adjusted so that the sphere is pushed to the center point and the rotating body is easily rotated.

Further, when the sphere (2) reaches the apex in the direction of the center point, the force for pushing the sphere back to the spring (3) is exerted.

[0024] The wavy unevenness provided inside the rotating body assists the strength of the spring and facilitates rotation.

It is because the sphere (2) located at the bottom (5) of the wavy unevenness is changed by the spring (when the claw (1) of the rotating body (7) hits an obstacle and the rotating body tries to rotate. While pushing 3) to the center point, it moves to the wavy unevenness apex (6), moves from the apex (6) to the next bottom, and at the same time, the next claw of the rotating body is sent out.

By providing a double or triple intersecting line on the wavy uneven portion inside the rotating body, irregular scratches can be given to the smooth road surface, which may be caused by a sidewalk tipping accident or a roadway slip. Prevents traffic accidents
