In addition, a retraction prevention plate 16 is installed in parallel with the push plate 15 on the rear side of the pressure mounter 10.

The retraction prevention plate 16 is for restoring the push rod 13 moved in the mounting portion 11 to its original position or preventing the push rod 13 from retreating in the other direction. The other end of the rod 13 is coupled through.

At this time, the retraction prevention spring 16a is mounted along the axial direction at the other end of the push rod 13 between the retraction preventing plate 16 and the pressure mounting device 10 so that the retraction is performed when the push rod 13 is moved. The retraction prevention plate 16 may prevent the retraction of the push rod 13 due to the elastic force of the prevention spring 16a.

In addition, when the push rod 13 is stopped and the push rod 13 is pulled back to its original position, the push rod 13 is pushed to the one side of the mounting part 11 by pressing the lower portion of the retraction preventing plate 16 to the original position. The elastic force of the anti-retraction spring 16a applied to the rod 13 is removed.

Figure 3 is a partial cross-sectional view showing the interior of the pressure packing according to the present invention.

As shown in Figure 3, the pressure packing 30 is a disk of a predetermined thickness, the rotating shaft 32 is coupled through the central portion, the mixing impeller 31 is mounted on one side of the rotating shaft 32 The mortar 200 is generated by mixing cement and water in the vessel 20 while rotating together with the rotation shaft 32. At this time, the pressure packing 30 is preferably made of elastic rubber or synthetic resin material to maintain the watertight.

In addition, the other side of the rotary shaft 32 is provided with a coupling groove (32a) formed in the inside is dug to a predetermined depth in a hexagonal shape so that the coupling rod (13a) of one end of the push rod 13 formed in a hexagonal shape is fitted. do.

When one end of the push rod 13 is coupled to the coupling groove 32a, the rotation knob 13b of the push rod 13 may be rotated and the rotation shaft 32 may be rotated.

On the other hand, the mixing impeller 31 is a predetermined number of wings are provided symmetrically with respect to one point so that the mixing ratio of the mortar 200 is increased, the number or size of the wings is the concentration of the mortar (200) It may be modified depending on the mixing ratio of cement, sand and water.

In addition, the rotation of the mixing impeller 31 may be possible in a state in which the container 20 is separated from the mounting part 11, and the container 20 in which the pressure packing 30 is mounted is separated from the mounting part 11. By connecting a rotating means such as a motor to the coupling groove (32a) to rotate the mortar 200 more efficiently than the manual rotation using the push rod (13).

And one side of the pressure packing 30 is formed with an injection hole 33 for injecting water, one end of the injection hole 33 is provided with a stopper plate 33a is a structure that can be opened only when the water injection to be.

The stopper plate 33a is an elastic material made of rubber or synthetic resin like the pressure packing 30 and is in close contact with the injection hole 33 to block the injection hole 33. At this time, in case of injecting water, the tube container (not shown) containing water is inserted into the inlet 33 and water is injected.

Here, the rod 33d is connected to the bottom of the stopper plate 33a so that the selective opening of the stopper plate 33a can be forced out.

The rod 33d is guided along the hollow shaft 33b to selectively move up and down the stopper plate 33a while being lifted up and down, and the hollow shaft 33b is pressurized packing in which the stopper plate 33a is positioned. 30) Fitted through the site.

The rod 33d is mounted with an elastic spring 33e along the axial direction to express an elastic force to return the stopper plate 33a to its original position when there is no further pressure after the injection of water is completed.

At this time, the flange 33c is integrally formed at one inner circumference of the hollow shaft 33b so that the elastic spring 33e holds the rod 33d to support one side of the elastic spring 33e.

In addition, the upper part of the pressure packing 30 is dug inwardly in correspondence with the shape of the stopper plate 33a so as not to protrude on the pressure packing 30 when the stopper plate 33a is not opened. .

Figure 4 is a state diagram used in the mortar injection apparatus according to the present invention.

As shown in Figure 4, the mortar injection device 100 is fitted to the coupling groove (32a) formed on the other side of the pressing plate 30, the contact plate 14 provided at one end of the push rod (13) It is a structure that pushes the mortar 200 contained in the container 20 to the outside through the outlet 21 by the piston movement by the pressure mounting device 10 for pushing the push rod (13).
