As shown in FIGS. 1 and 2, a concrete distributor capable of opening and closing the discharge port according to the present invention comprises a concrete distributor 1 and an outlet switch 10.

The concrete distribution unit 1 refers to all the concrete distribution units including the delivery pipe 2 for receiving and sending concrete, for example, a master 3 installed at a predetermined height on a building site of a concrete building; A swing frame (4) mounted on the master; A plurality of booms (5, 6, 7, 8) connected in a cascade foldable manner to the swing frame (4); And a feeding boom (2) arranged along the booms (5, 6, 7, 8) for feeding the concrete supplied from the concrete feeding part. The present invention is not limited to the above-described concrete distributor and is applicable to all of distributing concrete through the discharge pipe 2. [

The opening and closing device 10 is configured to open and close the discharge port of the discharge pipe 2, that is, to open the discharge port of the discharge pipe 2 when the concrete is poured, close the concrete pipe after completion of the concrete pouring, .

The switch 10 includes all the ways of closing the discharge port of the discharge pipe 2 and must be kept in a tight closed state so that the closed state is not changed to the open state by the pressure of the concrete. A switch main body 11 which is connected to the end of the delivery pipe 2 and an opening and closing plate 12 which opens and closes the inside of the switch main body 11. [

That is, even if the structure of the conventional delivery pipe 2 is not changed, there is an advantage that only the main body 11 of the switch can be connected to the delivery pipe 2 to be used.

The switch main body 11 has a structure which is formed at an outer diameter smaller than the inner diameter of the delivery pipe 2 and is inserted into the delivery pipe 2 and is connected to the delivery pipe 2 through a fixing band 13 Can be fixed.

In order to prevent the fixing band 13 from being detached when the fixing band 13 is applied, on the periphery of the main body 11 of the switch 11, for example, a ring-shaped engaging step 14 Is formed.

The opening and closing plate main body 11 is provided with an opening and closing plate mounting hole 15 between the both openings instead of opening and closing the lower opening of the opening and closing plate 12, So that the inside of the opening / closing plate main body 11 is closed. According to this configuration, since the opening / closing plate 12 is inserted into the switch main body 11 to receive the support of the bottom of the opening / closing plate mounting hole 15, the load remains in the closed state even when the load of the remaining concrete is heavy.

The opening / closing plate mounting hole 15 may be formed to be inclined downward toward one side for facilitating insertion and fitting of the opening / closing plate 12 and for maintaining a firm closed state.

The opening and closing plate 12 is composed of a plate-shaped blocking portion 12a inserted into the opening and closing plate mounting hole 15 and closing the inside of the switch main body 11 and a handle 12b extending from the blocking portion 12a.

The blocking portion 12a preferably has a size larger than a size that can block the inside of the switchgear main body 11 and the edge portion may protrude outside the switchgear main body 11. [

The handle 12b may be a plate extending at a constant angle or the same angle in the blocking portion 12a and is provided with a handle hole.

The opening and closing plate 12 must be separated from the opening and closing plate mounting hole 15 in order to open the outlet pipe 2. The opening and closing plate 12 is connected to the opening and closing main body 11 through the connecting wire 16, . The connecting wire 16 is fixed to both the periphery of the main body 11 and the opening and closing board 12 so that the opening and closing board 12 is stored in the opening and closing main body 11. For example, It can be wound in the form of a coil spring as much as possible.

Another method for storing the opening and closing plate 12 is to provide a hanger pin on the periphery of the opening and closing device main body 11 and to hold the opening and closing plate 12 on the hanger pin through the handle hole of the opening and closing plate 12 It is possible.

The operation of the concrete distributor capable of opening and closing the discharge port according to the present invention is as follows.

The discharge port of the delivery pipe 2, that is, the discharge port of the breaker 10 is moved to the position where the concrete is laid and the open / close board 12 is separated from the open / close plate mounting hole 15 of the breaker main body 11, 11) is opened. As a result, the delivery pipe 2 and the inside of the switch main body 11 communicate with the outside.

When concrete is supplied in this state, the concrete is fed through the feed pipe 2 and the inside of the switch main body 11 and then fed. At this time, although the opening / closing plate mounting hole 15 is open to communicate with the outside, the concrete is not discharged through the opening / closing plate mounting hole 15 due to the delivery pressure and gravity of the concrete. It does not adversely affect the casting of the concrete because it is discharged into the formwork.

When the concrete is poured through the above process, it must be moved to another place. When the blocking portion 12a of the opening / closing plate 12 is inserted into the opening / closing plate mounting hole 15, the inside of the opening / closing main body 11 is closed.

Therefore, even if there is residual concrete that has not been discharged to the outside in the discharge pipe 2, the residual concrete can not be discharged to the outside by the opening / closing plate 12.

Hereinafter, another example of the switch will be described.

5, the switch 20 includes a blocking block 21 inserted into a discharge port of the discharge pipe 2 and a discharge pipe 2 formed at a lower end of the blocking block 21 to have a sectional area larger than that of the blocking block 21, The free end is connected to a ring 23 formed in a circumferential portion of the delivery pipe 2 and is provided at a predetermined interval along the circumferential direction on the support jaw 22, And a locker (24) for supporting the tube (21) on the delivery pipe (2).

The blocking block 21 is inserted into the delivery pipe 2 in the form of a rod having the same cross section as the inside of the delivery pipe 2 and closes the discharge port of the delivery pipe 2.

The support jaw 22 has a function of preventing the concrete flowing between the blocking block 21 and the delivery pipe 2 from leaking to the outside and a function of supporting the delivery pipe 2, A ring-shaped cut-off step 22a may be formed.

The locker 24 prevents the switch 20 from being detached from the delivery pipe 2. The lower end of the reference is fixed to the support jaw 22 through a pin or the like and the upper end is caught by the ring 23, So as not to be separated from the delivery pipe 2. Two or more lockers 24 are applied.

The ring 23 is formed in the stationary ring and can be configured by fixing the stationary ring to the delivery pipe 2 with a fixing band or the like.

The switch 20 is housed in the delivery pipe 2 through the connection wire 25 or the hanger pin as described above.

6 shows another example of the switch, wherein the switch is a ball-type switch.

The balloon type switch 30 is inflated by the air filled therein to close the delivery tube 2 and is contracted by the air discharge to open the separation and delivery tube 2 at the delivery tube 2.

The balloon type switch 30 can be made of any material that is contracted by expansion and air discharge by the injection of air.
