Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an automatic snow throwing device for a snow removal system which is also applied to snow removal between cities, waste disposal, and the like.

(Prior Art) A conventional example of a snow removal system will be described with reference to FIGS.
The snow (a) brought into the snow treatment plant by the dump truck (b) is
It is thrown into the open water channel (c), crushed by a Bonskrie (d) with an electric motor (m) provided in the open water channel (c), introduced into the discharge pipeline (l), and water-fed by a pressure pump (pa). Snow is removed to the coast or the like through the snow separation device (f).
In addition, a water supply line (l ₁ ) with a pressure pump (pb) is provided in the open water channel (c) to secure desired snow transfer water in the open water channel (c).

(Problems to be solved by the invention) In the conventional snow removal system, a large-scale snow throwing system treats a large amount of snow, but the snow is thrown into an open channel and the snow is crushed by a ribbon screen pump. Since it is a method of transporting it, the processing capacity of the ribbon screen cannot be taken very much.When snow is thrown into the open water channel, snow accumulates on the surface and water only passes downward, making it difficult for the snow processing capacity. Due to the restrictions, there is a problem that the transportation capacity cannot be adjusted so much depending on the amount of snow input.

The present invention was developed to address the above-mentioned problems, and the purpose thereof is to operate a jet pump upon arrival of a snow-loaded vehicle and to take in and crush snow from a hopper by the jet pump. An object is to provide an automatic snow throwing device for a snow removal system, which has improved snow transportation capacity by supplying snow by a closed water channel and water transportation.

A snow supply line that merges and supplies to the side, a snow-injection hopper connected to the snow supply line, a jet pump provided in the snow supply line below the hopper, and an arrival of a snow-loaded vehicle to detect the arrival of the snow-loaded vehicle. It is characterized by a configuration that includes a control device that operates a jet pump.The control device automatically activates the jet nozzle upon detection of the arrival of a snow-laden vehicle, and the jet nozzle smoothes and supplies snow, and
The snow water transportation pipeline facilitates the snow water transportation.

(Function) The pressure pump pumps the snowwater pumping water to the snowwater pipeline, the partial pressure water is taken into the snow supply line from the downstream side of the pump pump, and the control device detects the arrival of snow-loaded vehicles. Then, the jet pump is automatically operated, and the snow introduced into the snow introduction hopper by the snow loading vehicle is taken into the snow supply line by the jet injection of the jet pump and crushed and supplied to the snow water transmission pipeline, Water is sent through the pipeline.

With snow intake and crushing by the jet pump,
The snow is smoothly and efficiently transported with a relatively small snow mixing ratio and the closed channel.
