Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ladle, and more particularly to a ladle for concrete slurry suitable for use as a slurry (fluid mixture) for concrete panels.

Concrete panels, whose demand has generally increased in recent years as a construction material, are made by pouring a slurry (fluid mixture) consisting of cement, admixtures, water, etc. into a frame placed in a formwork to level the surface. It is formed by curing.

In order to mass produce concrete panels, it is desirable that a series of processes such as panel frame formation, slurry production, slurry injection into formwork, curing, and demolding be integrated and continuous.

Even if we consider only the process from slurry production to injection, conventional concrete mixers, which are independent and tilt during pouring, are not suitable for an integrated panel production line.

Furthermore, it is necessary to consider the most effective ladle type in the overall panel manufacturing system, and conventional single ladle types have the disadvantage of not being able to be incorporated into the system line.

An object of the present invention is to provide a ladle for concrete slurry that can efficiently perform operations from slurry production to injection into formwork.

The present invention is capable of mixing cement, admixtures, water, etc. well, and furthermore, a screw having spiral blades facing in opposite directions to each other is provided in the hopper so that the slurry is concentrated into the spout, and an opening is provided above the hopper. By installing a pouring gate at the bottom, cement, admixture, water, or already mixed slurry can be injected from above and thoroughly mixed with a screw, while the lower gate can be opened to efficiently mold. The purpose is to inject slurry into the frame.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The ladle is provided with a hopper 1 consisting of a wide box body, and the width of this hopper 1 in the left-right direction in FIG. 1 is formed to match the width of the concrete panel to be manufactured.

The upper part of this hopper 1 is wide open, and the bottom part is formed of a semi-cylindrical curved surface with the longitudinal direction as the axial direction.

A plurality of slurry pouring ports 2, for example, three slurry spouts 2, are provided along the longitudinal direction of the hopper 1 on the lowest surface of the bottom, and these spouts 2 can be opened and closed from the outside, and each has a A gate 3 that can be driven independently is attached.

As shown in an enlarged view in FIG. 4, the structure of each of these gates 3 is such that a plate 5, on which a water-absorbing urethane sponge 4 is attached to the surface that contacts the spout 2 of the pumper 1, is connected to a connecting link 6 and a bell crank 7. It is a mechanism that opens and closes by being moved by a cylinder 8 via.

This cylinder 8 is attached to the bottom of the hopper 1 through a bracket 9, and when the tip of an adjusting screw 10 provided on the bracket 9 so as to be movable forward and backward is brought into contact with a predetermined position of the bell crank 7, the bell crank 2 F0 rotation angle,
That is, the degree of opening of the plate 5 can be adjusted.

Further, one end side of the plate 5 is rotatably supported by a bracket 12 via a rotating plate 11 so as to be freely slidable a predetermined distance, and this bracket 12 is also attached to the bottom of the hopper 1.

A screw 13 whose rotation axis is in the longitudinal direction of the ompper 1, that is, in the left-right direction in FIG. 1, is provided inside the ompper 1.

This screw 13 has spiral blades 15 around a shaft 14.
is attached, and furthermore, the direction of this spiral is configured to be reversed at the center of the screw 13.

As is clear from FIG. 2, in this embodiment, the left half of the center is formed with cloth-wrapped blades 15A, and the right half are formed with left and right blades 15B, respectively, and the shaft 14 is formed as shown by arrow A in FIG. When the hopper 1 is rotated to the opposite side, the slurry in the hopper 1 is moved from the left and right ends toward the center, respectively, as shown by arrows B and C in the figure.

A shaft 14 of the screw 13 is rotatably supported by bearings 16 provided on both IO surfaces of the hopper 1, and a sprocket 17 is fixed to one end of the shaft 14.

A geared motor 18 is provided on the front surface of the cut flopper 1, and a sprocket 19 is fixed to the output shaft of this geared motor 18, and this sprocket 19 is fixed to the shaft 14 of the screw 13 with a chain 20. It is connected to the sprocket 11.

Bearings 21 are attached to upper positions on both sides of the hopper 1, and wheels 22 are rotatably supported by the bearings 21.

The entire ladle consisting of the hopper 1 and the screw 13 is mounted on the wheels 22 on the knolls 2 provided above both sides of the formwork trolley.
It has a structure that allows it to move on three surfaces.

Further, both ends of a chain lever 25 are connected to both sides of the upper part of the hopper 1 via mounting brackets 24, and the other end of the chain lever 25 is hooked and rotated endlessly via two sprockets (not shown). The entire ladle is moved by driving this chino 25 with a drive side sprocket.

Next, the action will be explained.

The entire ladle is pulled by a cheno 25, supported by wheels 22, and moved on a knoll 23 to a slurry receiving port, where cement, admixtures, water, etc. are flowed down from an upper opening.
The hopper 1 is filled with slurry.

The slurry in homper 1 is transferred to screw 1 in homper 1.
3 by the guard motor 18, the ladle is moved to a fixed position from which the slurry flows out until the slurry is completely mixed.

'When the ladle reaches the place on the formwork where you want the slurry to flow down, that is, the fixed position, the plate 5 is moved by the cylinder 8.
The slurry in the hopper 1 is separated from the spout 2 on the lower surface of the hopper 1, the gate 3 is opened, and the slurry in the hopper 1 flows out.

When the screw 13 is rotated while the slurry flows out, the slurry is naturally collected in the center of the homper 1 due to the twisting direction of the blades 15, and the slurry is
The amount of slurry remaining inside will be very small.

After a predetermined amount of slurry has flowed out, the flow of slurry can be easily stopped by closing the gate 3 even in the middle.

In addition, a screw 13 is attached to the outer periphery of the Sufu 939130 blade 15 so that it is in contact with the semi-cylindrical curved surface of the bottom of the hopper 1, with almost no gap, and as the screw 13 rotates, the screw 13 is attached to the bottom of the hopper 1. The slurry is sent to the center without remaining.

When gate 3 is not open, slurry is in homper 1
The slurry in the upper layer is sent to the left and right center at the bottom of the screen, and the slurry in the upper layer is divided into left and right parts, and is sent to the screw 13 at both left and right ends.
Flows into the bottom where it is located.

Compared to the case where the screw 13 is twisted in one direction, the slurry in the pumper 1 is less biased, and the slurry is sufficiently mixed.

According to this embodiment as described above, a large amount of slurry can be mixed, transported, and injected at once, and since the gate 3 is provided on the lower surface of the hopper 1, the slurry can be flowed out without tilting the hopper 1. can be done.

In addition, a spiral screw 1 provided in the homper 1
3, the slurry is sufficiently mixed, and when flowing out, the slurry is concentrated in the center of the hopper 1. Even when it is necessary to flow the slurry down into a narrow formwork, the gates 3 on both sides are closed, and the central gate If this is done with 3 open, the slurry can flow out without leaving it in the hopper 1, and the slurry will not flow out to places other than necessary.

Furthermore, since the lower part of the hopper 1 has a semi-cylindrical shape and the upper part has a rectangular cylinder shape, and the screw 13 is provided in the lower semi-cylindrical part, the screw 13 can be removed when the gate 3 is closed. By rotating the screw 13, the slurry flows back through the upper part of the screw 13, and the slurry can be mixed more smoothly.

In addition, in implementation, it is not necessary to provide a plurality of each of the injection port 2 and the gate 3, and one may be provided over the entire width of the omper 1.

However, if it is divided into a plurality of pieces, it can easily be applied to molds of different widths, and the optimum injection can be performed depending on the width.

Furthermore, the structure of the gate 3 is not limited to the above structure, but may be any other structure.

Since the present invention has a ladle for concrete slurry configured as described above, it has the effect of being able to provide a ladle for concrete slurry that can efficiently pour slurry into a formwork.
