The vent part 500 functions to buffer scattering dust generated when the mixed cement falls into the storage transfer part 300 through the control part 200, and is simultaneously stored through the control part 200. By discharging the air flowing into the transfer unit 300 to the outside, the pressure inside the storage transfer unit 300 is prevented from increasing.

Therefore, the dust and air generated in the storage transfer part 300 rises up through the case 510 and the discharge protrusion 540, and the discharge protrusion 540 is covered with the second cover part 550. As a result, the dust falls back to the storage transfer part 300, and only air is discharged to the outside.

In addition, the second cover part 550 may prevent foreign matters from being introduced into the discharge protrusion 540.

The protective net 520 serves to prevent the user's hand or other objects from entering the storage transfer part 300 through the case 510 when the user opens the first cover part 530. .

The mixing unit 400 is formed to extend at one end of the storage transfer unit 300, the other end is open, the water supply port 410 for introducing the water introduced through the water supply unit 600 at the top Is formed.

The mixing protrusion 420 extended to the screw 320 is formed inside the mixing unit 400.

Therefore, the mixed cement introduced into the mixing unit 400 through the storage transfer unit 300 is mixed with water by the mixing protrusion 420 and discharged to the outside.

The water supply unit 600 is a device for supplying a predetermined amount of water to the mixing unit 400, as shown in Figures 5 and 6, the pump 610 and the water flowing from the pump 610 A flow meter 620 for maintaining a constant amount, an on / off valve 630 for opening and closing a flow path of water flowing from the pump 610, and mounted between the on / off valve 630 and the mixing unit 400. The solenoid valve 640 is automatically opened and closed by the control unit.

That is, the opening and closing valve 630 controls the opening and closing of the water by the user manually operating, the solenoid valve 640 is introduced into the mixing unit 400 by the controller when the opening and closing valve 630 is opened. Adjust the amount of water

The water supply unit 600 and the water supply port 410 of the mixing unit 400 are connected to each other using a hose 650 or the like.

In addition, the water supply unit 600 may be equipped with a separate bypass passage to clean the water by using the water discharged through the bypass passage after the completion of the work.

The control unit controls the discharge amount of the control unit 200 and the solenoid valve 640.

That is, when the amount of mixed cement accumulated in the storage transfer part 300 by the sensor 310 is equal to or less than a reference value, the blade 220 of the adjusting part 200 is rotated to allow the interior of the interbody 100. The mixed cement accommodated in the supply to the storage transfer unit 300 through the control unit 200, if the amount of the mixed cement accumulated in the storage transfer unit 300 is greater than or equal to the control unit 200 ) To stop the mixing cement contained in the interbody 100 from being supplied to the storage transfer part 300 through the adjusting part 200.

At this time, the rotation force of the first motor 240 is varied according to the measured value of the sensor 310 so that the mixed cement accumulates at a predetermined height in the storage transfer part 300.

As described above, when a predetermined amount of mixed cement is accumulated in the storage transfer part 300 by the sensor 310, the control part 200 is stopped, whereby the weight of the mixed cement contained in the interbody 100 is heavy. Even if it is blocked by the control unit 200 can be prevented from being discharged to the storage transfer part 300, the storage transfer part 300 can always be stored in a certain amount of the mixed cement.

In addition, by controlling the solenoid valve 640 so that the flow meter 620 has a constant value, it is possible to constantly adjust the amount of water flowing into the mixing unit 400.

As a result, the control unit may automatically maintain a constant ratio of the amount of mixed cement and the amount of water introduced into the mixing unit 400.

Operation method of the apparatus between the present invention made of the above configuration, as shown in Figure 7, measuring step (S100), discharge control step (S200), transfer step (S300), and mixing step (S400) Is done.
