Then the shaft is constituted so that the shaft 2 is provided with a spouting port 16 spouting water which has come by passing away through the water path close by an agitation blade 3 and a quantity of the water streaming through the water path is adjusted by the valve 5 provided in the middle of the water pipes 7a, 7b. Consequently, agitation work can be performed while adjusting a quantity of the water when need arises through opening or closing adjustment of the valve 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric stirrer used when stirring a material such as cement.

[0002]

2. Description of the Related Art Conventionally, when a material such as cement is mixed with water, a long rotary shaft is connected to the output shaft of an electric motor, and a stirring blade is attached to the tip of the rotary shaft. Work is performed using an electric stirrer with a structure.

At the time of this work, water is supplied to the material by another worker or by the worker himself by temporarily stopping the agitator. This not only has a poor working efficiency, but also has a problem in that it is difficult to control the amount of water.

Further, when working alone, it is impossible to stir while supplying water, so after the stirring, there are occasional failures such as excessive water notice and unavoidable addition of materials, which causes waste of materials. It became

The present invention has been made in view of the above, and is capable of easily supplying water while performing a stirring operation, and thereby an appropriate amount of water can be supplied.

[0006]

In order to solve the above-mentioned problems, the present invention is an electric stirrer capable of supplying water simultaneously with stirring. As a means for solving the problem, a rotary shaft connected to a main body containing an electric motor is provided with a tubular water supply passage, and a water distribution pipe for introducing water from the outside is provided through a valve, a pipe joint, or the like. Connect to the water supply,
The rotary shaft is provided with a jet outlet near the stirring blade for jetting water that has passed through the water supply passage. A valve for adjusting the amount of water flowing through the water supply passage is provided in the middle of the water distribution pipe.

[0007]

The electric stirrer of the present invention having the above structure is rotated by inserting the stirring blade downward into a container containing a material such as cement, and adjusting the opening / closing of a valve provided in the middle of the water pipe. Perform stirring work while adjusting the amount of water supply if necessary.

First, water reaches a valve through a water pipe. This valve regulates the amount of water flowing in the water supply channel. The water that has passed through the valve enters the water supply passage in the rotary shaft through the pipe joint and the like, flows through the water supply passage, and is ejected from the ejection port.

In use, since the rotary shaft is rotating, the jet outlet is also rotating, and water is jetted while drawing a spiral trajectory.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 shows an electric stirrer according to the present invention. The main body 1 is configured by a frame that constitutes the outer shell of the electric stirrer, and the handle 4 is attached to the upper portion of the main body 1. The rotating shaft 2 is connected to the output shaft 9 of the electric motor built in the main body 1 via a gear case 6 having a bearing 14 built therein and a holder 10. Rotating shaft 2
A stirring blade 3 formed in a screw shape is attached to the tip of the.

Further, a valve 5 for adjusting the amount of water is attached near the handle 4 of the main body 1, and the tank 1 for storing water
A water pipe 7 a connected to 7 is connected to one end of the valve 5. The water distribution pipe 7b is connected to the other end of the valve 5, and the other end of the water distribution pipe 7b is connected to the pipe joint 8.

FIG. 2 is a longitudinal sectional view of the water distribution pipe 7b, the pipe joint 8, the inside of the gear case 6 and the rotary shaft 2. Pipe fitting 8
Is connected so that water flows in a ring-shaped groove 12 provided on a surface in contact with the output shaft 9 inside the gear case 6,
Sealing seals 13 for preventing water leakage are mounted above and below the groove 12. The groove 12 is connected to the water supply passage 11a provided in the output shaft 9 in the vertical direction by the opening 15 provided in the output shaft 9. The output shaft 9 is connected to the rotary shaft 2 via a holder 10. Rotating shaft 2
Is provided with a water supply passage 11b in the vertical direction, and a jet outlet 16 is provided near the tip end where the stirring blade 3 is attached.

FIG. 3 is a cross-sectional view of the inside of the gear case 6, showing the structure of the groove 12. The water supply passage 11 b provided inside the rotary shaft 2 is connected to the groove 12 at the opening 15.

FIG. 4 is a cross-sectional view of the rotary shaft 2 at the ejection port 16. The jet ports 16 are provided on all sides of the water supply passage 11b.

The water stored in the tank 17 is distributed to the water distribution pipe 7a.
Through the valve 5 into the water distribution pipe 7b, and is introduced into the agitator from the pipe joint 8. Water introduced from the pipe joint 8 is supplied to the groove 12 in the gear case 6 and the water supply passage 11 in the output shaft 9.
a, the holder 10, the water supply passage 11b in the rotary shaft 2,
It spouts from the spout 16.

Since the spout 16 is provided on the rotary shaft 2, water spouts from the rotating spout 16 while drawing a spiral trajectory.

As shown in FIG. 3, the opening 15 is always connected to the groove 12 while the output shaft 9 is stopped or rotating,
Water is continuously supplied to the water supply passage 11a.

The water distribution pipes 7a and 7b are made of synthetic resin, rubber or the like. However, when the water distribution pipe 7b is directly connected to a faucet, it is desirable to use a pressure resistant hose for the water distribution pipe 7a. ..

[0020]

As described above, according to the electric stirrer of the present invention, the operator can supply water without the assistance of others and without interrupting the stirring work, and the amount of water supply can be adjusted. Because it is also easy, work efficiency is improved.

Further, since the stirring and the water supply can be performed at the same time as described above, it is possible to supply the water while observing the state of the material, so that it is possible to prevent the excessive filling of the water and thereby prevent the waste of the material.

Further, since the ejection port is provided on the rotating shaft, water is ejected from the rotating ejection port in a spiral trajectory. Since water is dispersed and supplied in this way, it is easy to be compatible with the material and the stirring efficiency is improved.
