Description

[Detailed Description of the Invention] This invention relates to a two-component backfilling material mixing and filling device used for filling a backfilling material when repairing cracks in concrete buildings or preventing peeling of exterior materials.

Two-component backfilling materials not only cannot achieve the desired strength unless the two components are mixed uniformly, but if they are mixed in advance before use, they will harden during the filling process. This impairs workability, and if the used material remains, it will harden, so the mixed backfill material cannot be stored and used for the next work, resulting in wasted material, and it is difficult to handle mixed scattered backfill material. Another problem was that it adhered to the human body, making it difficult to remove it quickly.

As an idea aimed at solving the above problems, a caulking gun (Jikkosho 48
-6837), but the device disclosed in the above specification relies solely on the blades attached to the rotating shaft to stir and mix the two liquids, making it difficult to obtain a sufficient mixing state. In addition, since the mixed backing material is pushed out of the nozzle by the pressure used to force-feed the two liquids to the stirring mechanism, the two liquids are forced to be fed to the stirring mechanism with relatively high pressure, and as a result, the two liquids There was a problem that it was easy to be discharged from the nozzle without being sufficiently stirred.

However, in this invention, a stirring member was provided protruding from both the inner wall of the mixing chamber and a rotating shaft inserted into the mixing chamber, and a pressurizing device was attached to the nozzle.
Send a predetermined amount of two liquids to be mixed into the mixing chamber,
This makes it possible to stir and mix uniformly, thus solving the above-mentioned conventional problems.

This invention will be explained below based on embodiments shown in the drawings.

A mixing chamber 2 is housed on one side of a cylindrical casing 1, and a nozzle device 3 is detachably attached to the mixing chamber outlet side end of the casing 1.

The mixing chamber 2 is provided as the inner cavity of a cylindrical body 4 that is inserted into and removed from the casing 1, and a rotating shaft 5 is inserted through the center of the mixing chamber 2. On the inner wall of the cylindrical body 4, a plurality of pairs of stirring rods 6, 6a sandwich the rotating shaft 5, and diametrically:
and are protruded at equal intervals, and the rotating shaft 5
A plurality of pairs of stirring rods 7, 7a which stir together with the stirring rods 6, 6a are protruded diametrically and at equal intervals.

One side of the cylindrical body 4 is closed with a closing plate 8,
A shaft insertion hole 9 is provided in the center of the closing plate 8, and liquid passage holes 10, 10a are provided on both sides. One end of the connecting pipe 11, 11a is screwed into the mixing chamber side of the liquid passage hole 10, 10a, and
One end of the liquid feed pipes 12, 12a is screwed onto the other side, and the other end of the liquid feed pipes 12, 12a protrudes outside the casing from a through hole provided in the cap 13 of the casing 1. In the figure, 14 and 14a are hose connection ports.

One end of the rotating shaft 5 is inserted into the shaft insertion hole 9 of the closing plate 8, and the rotating shaft 5 is connected to the coupler 15,
It is connected to a shaft 19 of a motor 18 via a reduction gear group 16 and a coupler 17. Further, one end of an inner cylinder 21 is screwed onto the outside of the closing plate, and the motor 18 and the reduction gear group 16 are housed within the inner cylinder. In the figure, 20 is a packing that supports the motor 18, and 22 is the packing and the cap 13.
The spring 22 is a spring interposed between the casing 1 and the casing 1, and the spring 22 constantly presses the motor 18 toward the mixing chamber, and when the nozzle device 3 is removed from the casing 1, the cylindrical body 4 comes to protrude from the casing 1. ing.

The nozzle device 3 has a cylinder 24 connected to a cylindrical body 23 that is screwed into the casing 1, and
A through hole 25 for passing the mixed liquid is formed on one side of the cylindrical body side (upper side in FIG. 1) of the cylinder, and a nozzle pipe 26 is connected to the other side of the cylinder 24, and a through hole 27 is provided between the two sides. 29 in the figure, and a piston 28 is fitted into the cylinder 24.
3 is a handle for operating the piston, and 30 is a pressure gauge.

Next, the operation of the filling device shown in the above embodiment will be explained.

When the hoses for pumping the two liquids of the backfilling material are connected to the hose connection ports 14 and 14a, and the input is input to the motor 18 to rotate the rotating shaft 5, the two liquids of the backfilling material supplied from the hoses are respectively Liquid feed pipe 12,
12a, and reaches the mixing chamber 2 via the connecting pipes 11 and 11a. In the mixing chamber, a stirring rod 7 protruding from the rotating shaft 5,
7a is rotating, due to the action of the stirring rods 7, 7a and the stirring rods 6, 6a protruding from the inner wall,
While being stirred and mixed, the two liquids move toward the through hole 25 due to the inflow pressure, and reach the inside of the cylinder 24 through the through hole 25 in an evenly stirred state.
After the mixed backing material enters the cylinder 24, push down the handle 29 and move the piston 28 to the arrow 3.
When the cylinder is slid in the direction 1 (see FIG. 1), the backing material inside the cylinder is discharged under pressure through the nozzle pipe 26.

According to the above embodiment, since the cylindrical body 4 is made removable, the cylindrical body 4 or the motor 18 can be taken out by removing the nozzle device 3 from the casing 1, making it easy to clean.

In the above embodiment, the stirring member provided on the rotating shaft and the inner wall of the mixing chamber is a stirring rod, but the stirring member is not limited to a rod shape, and may be a protrusion having an appropriate width. Further, the mixing chamber does not necessarily need to be constructed by incorporating a cylindrical body inside the casing, and the stirring member may be provided directly protruding from the inner wall of the casing.

In other words, according to this invention, since the stirring member is provided protruding from both the inner wall of the mixing chamber and the rotating shaft inserted into the mixing chamber, it is possible not only to improve the stirring efficiency of the two liquids, but also to apply pressure to the nozzle. Since the device is attached, it is possible to send a predetermined amount of the two liquids to be mixed into the mixing chamber at relatively low pressure, which has the effect of uniformly stirring and mixing without putting an excessive burden on the stirring device. be.
