Abstract

PURPOSE:To effectively transport snow by a small-size equipment in which water is jetted from the upper side of a snow grid to the lower side by a water jet machine. CONSTITUTION:Water in a space 5 surrounded by a snow grid 4 and a guide 3 in a pit 2 is jetted from the lower end to the upper side of the snow grid 4 along the guide 3 by means of a water jet machine 6. The snow pieces S coming down with water from an upper snow-flowing trench 1A to the pit 2 move toward the lower side on the snow grid 4. The snow pieces S coming toward the lower side on the snow grid 4 are directed forcibly into a lower snow-flowing trench 1B by water jet when they reach the lower end of the snow grid 4.

A snow grate 4 is horizontally installed on the groove bottom extension of the upstream snow drifting groove 1^ in this guide member 3. The snow grid 4 in this embodiment is made of a punching plate in which a large number of circular holes 4a are punched out at equal intervals.

In addition, since the water in the bit 2, particularly in the space 5, is configured to be sprayed along the gutter-shaped guide member 3 by the underwater jet machine 6, the inclination angle of the gutter-shaped guide member is set to be relatively steep. However, water gushes out in a concentrated manner. Therefore, since the longitudinal dimension is reduced, miniaturization is achieved, and the installation space can be reduced. Moreover, underwater jet machine 6
Since the upper side is covered by the snow grid 4, even if hard foreign objects such as stone blocks are transferred to the bit 2 along with the snowflakes S, this foreign object will not interfere with the underwater jet machine 6 at all, so that the underwater jet will not flow. Not only can damage to machine 6 be prevented, but even if a person accidentally falls into bit 2,
It will not be damaged by the underwater jet machine 6.

In the embodiment, a large number of circular holes 4 are used as the snow grid 4.
Although the explanation uses an example using a punching plate in which holes 4a are punched out at equal intervals, as shown in FIG. good. Alternatively, a configuration in which through holes are formed in other geometric shapes may be used. Furthermore, the formation intervals of the through holes may not be uniform in the longitudinal direction of the snow grid 4, but may be formed at coarse intervals on the downstream end side, that is, in the region where water is jetted.

(Effects of the Invention) As explained above, according to the present invention, a gutter-shaped guide member that is inclined upward from the upstream side to the downstream side is inserted into the bit provided in the middle of the snow drifting groove. A snow grate is installed horizontally on this guide member, and the water that flows into the space surrounded by the snow grate and the guide member is spouted out above the snow grate along the guide member to remove snowflakes on the snow grate. Since the configuration is such that an underwater jet machine is installed to transfer the snow to the downstream side, even if the guide member is installed at a relatively steep angle of inclination, the water can not be jetted from the top of the snow grate to the downstream side by the underwater jet machine. As a result, the device can be made compact, requiring only a small installation space, and the water spouted onto the snow grate can actively cause the snowflakes to flow downstream, improving snowflake transfer efficiency. Moreover, since the guide member and the underwater jet machine can be integrated into a unit, installation and disassembly are easy, and since the upper side of the underwater jet machine is covered with a snow grid, safety for the underwater jet machine and the human body is improved. It has effects such as high
