Description

Detailed Description of the Invention (Industrial Application Field) The present invention is applicable to, for example, a spraying machine that sprays mortar, concrete, etc. onto an appropriate spraying surface such as a slope for constructing a retaining wall, or a lawn sprayer. This is installed in a spraying machine that sprays seeds, etc. together with soil for greening onto an appropriate spraying surface such as a slope or vertical surface in order to plant flowers, etc., and it is necessary to improve the fixation of these sprayed materials to the sprayed surface. This invention relates to a thread-like material mixing device that is capable of continuously and smoothly spraying appropriate thread-like material together with the object to be sprayed, in order to improve the quality of the product.

(Prior art) Conventionally, when spraying mortar, concrete, etc. onto an appropriate spraying surface such as a slope, the mortar, concrete, etc. is stirred and kneaded in advance using a spraying machine, and then the mortar, concrete, etc. is mixed and mixed through a hose. It was force-fed to the spray nozzle at the tip and sprayed at the desired position from the tip of the spray nozzle.

In addition, when spraying seeds, etc. together with greening soil on an appropriate spraying surface such as a slope or vertical surface, the soil mixed with seeds is fed to the spray nozzle via a hose, and A sticky agglomerate was fed through a hose to a spray nozzle, and the spray nozzle sprayed the agglomerate and seed-containing soil to desired locations and fixed them.

Furthermore, there is the use of this material in building materials, earth mounds, pavements or blocks, and methods and apparatus for the production of this material, as described in JP-A-55-167170. This includes means for forming a flow of fluid, means for supplying a continuous element, means for introducing this element into the flow of fluid, and a proportion of said fluid, said continuous element and said mass of particles. a nozzle having means for progressively mixing and means for discharging the fluid from the mixture, the nozzle being connected to a source of pressurized fluid, the nozzle being connected to a source of solid particles; The flow of fluid flowing out of the nozzle creates negative pressure suction on the particles.

(Problem to be Solved by the Invention) However, conventional spraying machines simply spray the material to be sprayed, such as mortar, concrete, and soil for greening, onto an appropriate spraying surface such as an inclined surface or a vertical surface. However, because of this, there were problems such as poor adhesion to the sprayed surface and sagging of the sprayed surface. In addition, if the adhesiveness of the sprayed material is increased in order to prevent these problems, there are problems such as increased flow resistance and the need for strong spraying pressure. Furthermore, when spraying materials such as soil for greening, there was a risk that the sprayed soil layer would become hard due to the adhesive and become unsuitable for growing seeds.

Furthermore, the use of this material for building materials, earth mounds, pavements, or blocks as described in Japanese Patent Application Laid-open No. 55-167170, and the method and apparatus for manufacturing this material, are as described above. Although we were able to solve the problems to some extent, there was a problem in that the state in which the thread was pulled out could not be adjusted. That is,
The state in which the thread is pulled out differs depending on the strength of the water pressure (amount of water). The ratio of water to be mixed is determined, and the strength of water pressure (amount of water) cannot be easily changed. However, the problem was that it was difficult to mix with other substances.

(Means for Solving the Problems) Therefore, the present invention was created in order to solve the above-mentioned difficulties, and specifically, it applies to sprayed materials such as mortar, concrete, and soil for greening. In the spray machine 20, which can spray on an appropriate spray surface such as an inclined surface or a vertical surface, the object to be sprayed is sprayed from the spray machine 20 through the hose 22 until it is sprayed from the tip of the spray nozzle 21. Interposed in the feed path,
This is a filamentous material mixing device S configured so that a filamentous material T for mixing is continuously fed from the outside into a feeding path of a material to be sprayed, so that the mixed filamentous material T can be continuously sprayed together with the material to be sprayed. . Then, a substantially cylindrical mixing case 1 that can be inserted into the feeding path of the material to be sprayed, and a mounting hole 12 formed in the peripheral wall of this mixing case 1 are installed, and a filamentous material The mixing case 1 is provided with a mixing guide body 2 having an insertion hole 2a through which a T can be inserted, and the mixing case 1 is connected to a mounting hole 12, and high-pressure air or high-pressure liquid is introduced into the mixing case 1 from the mounting hole 12. The mixing guide body 2 is attached to the mixing case 1 so that it can move forward and backward into the mounting hole 12 by rotation. The outer peripheral surface of the tip part of the mixing guide body 2 and the mixing case 1 are moved forward and backward.
The high-voltage electricity or high-pressure liquid supplied to the inlet port 14 is fed to the attachment hole 12, and the gap between the inner circumferential surface of the attachment hole 12 and A means is adopted in which the liquid is fed into the mixing case 1 from between the outer circumferential surface of the tip portion and the inner circumferential surface of the mounting hole 12.

(Function) Therefore, the mixing case 1 is interposed at an appropriate position in the supply path of the material to be sprayed, from the spray machine 20 through the hose 22 to the point where the material is sprayed from the tip of the spray nozzle 21. , the hollow portion is in communication so as to become a part of the sprayed material feeding path.

Further, in the mixing guide body 2 attached to the mixing case 1, the mixing thread T is inserted into its insertion hole 2a, and the mixing thread T, which can be inserted freely through the insertion hole 2a, feeds the material to be sprayed. It is smoothly fed within the channel towards the tip. Moreover, the mixing guide body 2
is moved forward and backward within the mounting hole 12 by its rotational operation, and the gap between the outer peripheral surface of the tip portion of the mixing guide body 2 and the inner peripheral surface of the mounting hole 12 of the mixing case 1 can be freely moved. adjusted.

High-pressure air or high-pressure liquid is supplied to the mixing case 1 from the inlet 14 , and the high-pressure air or high-pressure liquid is delivered to the outer peripheral surface of the second tip portion of the mixing guide through the mounting hole 12 and to the mounting hole 12 . It is fed into the case 1 for mixing by passing through the space between it and the inner peripheral surface, and at this time, the filamentous material T for mixing comes to be pulled out. That is, the speed at which high-pressure air or high-pressure liquid passes between the outer peripheral surface of the tip portion of the mixing guide body 2 and the inner peripheral surface of the refeeding hole 12 influences the pulling force of the thread-like material T for mixing. This adjustment is performed by rotating the mixing guide body 2.

Then, the mixing filament T is continuously drawn into the tip of the sprayed material feeding path by the sprayed material fed through the sprayed material feeding path, and together with the sprayed material. It is sprayed from the tip of the spray nozzle 21.
