Description

[Detailed explanation of the idea] The present invention relates to an improvement of a soil spraying nozzle.

When spraying muddy soil onto a slope to form a top soil layer, the muddy soil will wash out and it will not be possible to spray the soil to the thickness required for the vegetation, so it will be necessary to spray it two or three times to cover the vegetation. The actual situation is that the necessary soil layer is formed, but there is a drawback that the construction work is extremely complicated.

In order to improve this problem, it is known from Japanese Patent Publication No. 11604/1983 to mix and spray a coagulant into the pipe while pumping the slurry-like vegetation base material.

However, although this method allows the vegetation material to adhere to slopes etc. through its adhesiveness, in the case of a soil layer mainly made of soil, it cannot consolidate and form a soil layer suitable for vegetation, and it is particularly difficult to If a flocculant with high flocculating performance is used to aggregate the soil layer, there is a problem in that the discharge hole is clogged and spraying becomes impossible.

This invention relates to a soil spraying nozzle that mixes a high-performance flocculant immediately after discharging muddy soil to easily form a soil layer with an aggregate structure, and connects the muddy soil delivery hose. A flocculant container connected to a flocculant supply hose is connected to the discharging port at the tip of the tapered mud spraying pipe, and the front end of the flocculant container has an inner diameter equal to or larger than the inner diameter of the discharge port relative to the discharge port. The gist of the system is that it is equipped with a stirring cylinder.

An embodiment of the present invention will be described with reference to the drawings. A muddy soil supply hose 1 is configured to forcefully transport muddy soil material using a chiller pump. A tapered muddying pipe 2 is attached to the tip of the muddy soil feeding hose 1. The tip discharge port 3 is detachably attached to the rear end of the flocculant container 4, and a stirring cylinder 5 having an inner diameter equal to or larger than the inner diameter of the discharge port 3 is provided at the tip of the flocculant container 4.
is removably attached so as to face the discharge port 3 , and a flocculant liquid supply hose 7 is further connected to the flocculant container 4 via an adjustment pot 6 .

The stirring cylinder 5 is provided with stirring blades 8, and a rectifying cylinder 10 having a diffusion and stop valve 9 can be provided at the front of the stirring cylinder 5, if necessary, to give directionality to the sprayed material.

Since the embodiment of the present invention is constructed as described above, the slurry pump discharges the muddy soil mixed with seeds, fertilizers, etc. from the discharge port 3 of the muddy soil spraying pipe 2 through the muddy liquid supply hose 1. A high-performance flocculant such as a polyacrylamide hydrolyzate or a polyacrylamide-sodium acrylate copolymer is pumped into the flocculant container 4 via the flocculant feed hose 7 using a gear pump, and the two are mixed and then fed from the stirring cylinder 5. This method forms a layer of sprayed soil on a predetermined slope.

In the present invention, a flocculant container is connected to the discharging port at the tip of a tapered mud spraying pipe to which a mud feeding hose is connected, and a flocculant container is provided at the front end of the flocculant container opposite to the discharging port with an inner diameter equal to or larger than the inner diameter of the discharging port. Since a stirring cylinder with an inner diameter of It has excellent characteristics and practicality in that it can form a soil layer with a grain structure.
