JPS6019606A - Power-driven snow scraper - Google Patents

Abstract

PURPOSE:To mechanize an operation for removing snow from a building roof, by providing an U-shaped snow scraping tool at the end of a slide plate which can advance and retreat, and by adapting the scraping tool to scrape snow on the roof as the advanced slide plate retreats, while making the scraped snow to slide on the slide plate. CONSTITUTION:A mounting support 5 is set on the eaves of a roof and a slide plate 2 is extended out through rotational drive by a feed roller 4. The sliding plate 2 is subsequently wound up by a winding roller 3 to draw a snow scraping tool 1. The scraping tool 1 thereby scrapes snow cumulated on the roof while transferring it to the upper side to release it onto the slide plate 2. The snow slides on the slide plate 2 to be discharged from the roof. By such constitution, a work for removing snow from a roof can be mechanized.

Description

DETAILED DESCRIPTION OF THE INVENTION The object of the present invention is to use mechanical power to remove snow accumulated on sloped surfaces such as the roofs of houses in multilingual areas.

In the past, most of the snow was removed manually using shovels, shovels, etc., by throwing it off the roof, or by using a slide.

On the other hand, snow-melting roofs have recently been partially implemented, but the current situation is that roof heaters or the use of electricity and kerosene to heat water are very expensive, so they are not widely used.

An embodiment of the present invention will be described below. FIG. 1 is a perspective view of the present invention, FIG. 2 is a sectional view of the E section, and FIG. 3 is a side view. In the figure, (1) is a snow cutting tool made of a steel plate having a horizontal U-shape, and is fixed to the tip of a sliding plate (2). (2) is a flexible sliding plate, which is a steel plate formed into an arched shape in the width direction, as shown in the cross-sectional view of Figure 2, and has a structure that does not bend even when a load is applied from the top. There is. (3) is a winding roller for winding up the sliding plate (2) connected to a drive unit containing a motor and a speed reducer. (4) is a feed-out roller which is also connected to the drive unit, and is a roller that is driven when sending the sliding plate (2) forward. (5) is a portable installation stand on which the present invention is mounted.

The present invention configured as described above will be explained in detail. First, place the installation stand (5) of the power-driven snow blower of the present invention on the eaves side of the roof where there is snow, and install the device with the side with the cutting tool (1) facing the upper side of the slope of the roof. . Next, turn on the separately provided operation switch and rotate the feed roller (4).
Send the sliding plate (2) forward, move the cutting tool (1) to a predetermined position, then turn on another switch, rotate the take-up roller (3), and move the sliding plate (2) to the installation stand (5). ). At this time, the cutting tool (1) cuts the snow from the opening at the bottom of the sliding plate (2) 7, and at the same time
The shaved snow is taken into the inside of the shape, and the taken in snow flows in a U-shape inside the cutting tool (1), reverses upward, moves to the top surface of the sliding board (2), and then moves to the top of the sliding board (2).
2) Since it slides on the installation platform (5), which is sloped, it slides along the slope and is discharged from the roof. Next, move the installation stand to another location and repeat the same operation as above to complete snow removal one by one.

As described above, the present invention is a machine that eliminates the conventional difficulty of relying on human power to remove snow accumulated on a roof, and makes it possible to perform the task of snow removal using power. Since the present invention is a lightweight machine, it can be carried freely by one adult, and it is also possible to eliminate in advance not only roofs but also sloped surfaces such as road sides where snow may fall onto the road.

Claims (2)

[Claims] (1) Rotate the delivery roller (4) connected to the drive unit, send out the sliding plate (2), and insert the horizontal U-shaped snow cutting tool (1) attached to the tip of the sliding plate (2). Slide it onto the specified snow, then rotate the winding roller (3) connected to the drive unit, and when winding up the sliding board (2), the snow will be removed by the underside of the horizontal U-shaped snow cutting tool (1). When the winding roller (3) rotates, the snow that has been scraped off is removed by the cutting tool (1).
), it is configured to be turned upside down, moved to the top surface of the sliding plate (2), slid on the sliding plate (2) and discharged, and is attached to a portable installation stand (5). A powered snow blower characterized by: (2) The powered snow remover according to claim 1, wherein the sliding plate (2) receiving a load has a curved structure to prevent bending.
