Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a water nozzle for removing snow from a road surface, which sprays water on accumulated snow on a road surface to melt the snow.

[Problems to be solved by conventional techniques and ideas]

Road snow removal equipment was born in the snowy country of Niigata Prefecture, and many applications have been filed for water spray nozzles for road snow removal.

However, in most of these types of snow-melting water nozzles, the water sprinkling holes are drilled through the ceiling wall or the screw-mounted lid plate.

The sprinkler holes penetrated in this way are easily clogged with gravel and pebbles that are exactly the same size as the hole diameter, and once gravel and pebbles become clogged, it is necessary to unclog the holes by pushing out the gravel and pebbles one by one with a needle bar.

For this reason, a structure in which a lid plate is screwed onto the top wall that can be removed has been adopted, and in the event of a blockage, the lid plate can be removed to clear the blockage.

However, removing the lid plate does not clear the clogging, but instead requires holding the lid plate in your hand and sticking the needle bar into the clogged watering hole. be.

How to prevent or clear clogging, which requires such troublesome clearing work, has been considered an important problem for snow-melting water nozzles, but so far there has been no good solution, and at most the lid plate has been removed. The only proposed method is to use a removable screw-on style, and when it becomes clogged, remove the lid plate and remove gravel and pebbles.

The applicant is also a snow removal nozzle manufacturer and has been conducting research to solve this problem.

In addition, the lid plate is configured in a simple fitting style instead of a screw type, and a separate fastening mechanism is provided for fixing the lid plate, and a water spray groove is installed diagonally on the circumferential surface of the fitting part of the lid plate. They developed a completely new water spray nozzle for road snow removal, in which the clogged gravel can be released from the groove by removing the cover plate.

[Means to solve the problem]

The gist of the present invention will be explained with reference to the accompanying drawings.

A water chamber 4 that is open at the top is provided in the upper part of the nozzle body 1, and a vertical water passage hole 5 is formed in the center of the bottom of the water chamber 4 to penetrate toward the bottom surface of the nozzle body 1.
The lid body 2 that closes the water chamber 4 is removably fitted onto the upper part of the water chamber 4, the fitted state is fixed by the fastening means 10, and the lid body 2 is fitted at multiple points on the fitting circumferential surface from the lower edge to the upper edge. A plurality of water sprinkling grooves 8 which are inclined in the same direction are recessed along the fitting peripheral surface, and the water sprinkling grooves 8 and the water chamber peripheral surface 4' form an inclined water sprinkling hole b. The present invention relates to a water spray nozzle for removing snow from a road surface, which is characterized by having a water spray amount regulating valve mechanism 3 vertically disposed in the center thereof.

[Effect]

For example, groundwater pumped by a pump passes through underground piping and is sent from a rising branch pipe 6 to a vertical water passage hole 5 of the nozzle body 1.

A constant amount of this groundwater is forced into the water chamber 4 via the water sprinkling amount control valve mechanism 3, and is formed by a water sprinkling groove 8 recessed along the fitting peripheral surface of the lid body 2 and the water chamber peripheral surface 4'. Water is sprinkled onto the road surface 14 from the inclined water sprinkling holes b.

At this time, since the watering grooves 8 are installed diagonally in the same direction, the slanted watering holes b are also installed diagonally, and the watering on the road surface is the same as the conventional watering from the watering holes diagonally drilled through the ceiling wall or lid body. Similarly, water is sprinkled diagonally, and if the water sprinkling grooves 8 are arranged at equal intervals, water will be sprinkled evenly around the area.

If gravel or pebbles enter the inclined watering hole a and cause clogging, releasing the fastening means 10 and removing the cover body 2 exposes the watering groove 8, so that the gravel can be easily removed. Become.

〔Example〕

To explain based on the embodiment of the present invention, the water chamber 4
The lid body 2 has a fitting circumferential surface 2' formed in such a manner that it is fitted with a taper, and a water sprinkling groove 8 is diagonally provided on this fitting circumferential surface 2'. It is effective to install, for example, four water sprinkling grooves 8 diagonally in the same direction, as water is sprinkled evenly and at a low level around the area. In addition, the tapered fitting state is more effective both in terms of fixing and in reducing water sprinkling.

There are a plurality of fixing means 10 for the lid body 2 (two in the drawing).
The figure shows a case where the fixing bolt of the main body is penetrated and locked into the lid body 2, and the lower end is screwed into the bottom of the water chamber 4 and fixed.

The water passage vertical hole 5 has a larger diameter at the bottom and is a rising pipe 6.
, and bury the nozzle body 1 so that the upper surface of the nozzle body 1 is aligned with the road surface 4.

The water sprinkling amount adjusting valve mechanism 3 is screwed into a screw hole 9 in the center of the lid body 2, and is adjusted up and down to adjust the valve rod 11.
Although the illustrated example shows a type in which the water sprinkling amount is adjusted by adjusting the size of the water passage hole a formed by the notch 12 provided in the hole 12 and the upper edge of the water passage vertical hole 5, other types may be used. Various valve mechanisms may be employed.

In the figure, numeral 7 is an O-ring gasket, and 13 is a rubber blind lid.

[Effect of idea]

Since the present invention is constructed as described above, if the inclined watering hole b becomes clogged with gravel or pebbles, the watering groove 8 will be exposed when the cover body 2 is removed, which will cause the clogging. Gravel, pebbles, and other dust can be easily removed, making the work of removing clogging, which was extremely troublesome in the past, extremely easy.

In addition, in the watering state, the watering grooves 8 are installed diagonally in the same direction along the fitting circumferential surface of the lid body 2, so the watering grooves 8 are arranged low and diagonally and at regular intervals like the conventional diagonal perforation type watering holes. If placed in the area, water can be sprinkled evenly around the surrounding area.

In addition, while conventional water sprinkling holes were very difficult to drill, the water gutter of the present invention is formed by cutting grooves, so it is extremely easy to manufacture compared to drilling holes, making it highly practical for road snow removal. It becomes a watering nozzle.
