Description

Description: FIELD OF THE INVENTION The present invention relates to a concrete bucket used for placing low slump concrete.

(Prior Art) Generally, in concrete pouring, a concrete pump or a concrete bucket is used as a means for conveying concrete to a pouring position. Due to its performance, the concrete pump is capable of conveying only so-called concrete having a high fluidity, that is, a high cement slump and a high slump concrete having a high water content, and a low fluidity low slump desired in this kind of industry. Not suitable for transporting concrete.

Therefore, in order to convey low slump concrete, concrete buckets of various structures have been proposed. For example, the configuration disclosed in JP-A-62-206168 is well known as a conventional example. The concrete bucket of this conventional example is composed of a cylindrical discharge hopper that is integrally provided in the central portion of the bottom of the bucket body in the longitudinal direction, and a screw rotatably disposed in the discharge hopper. A predetermined amount of concrete is discharged by rotating the screw.

In addition, Japanese Utility Model Laid-Open No. 62-78405 and Japanese Utility Model Laid-Open No. 58-1.
The structure disclosed in Japanese Patent No. 031 is also well known as a conventional example. The former case of this conventional example relates to a movable concrete automatic placing machine used in the production of a precast concrete slab, which is a moving frame that is moved forward along the upper surface of the bottom formwork, A concrete supply hopper having a concrete outlet in the lower rear part and a horizontal screw feeder inside is attached, and a compaction vibrating body that moves together with the hopper is provided behind the hopper. ,
A predetermined amount of concrete is discharged by rotating the screw feeder.

Also, in the latter case, the present invention relates to a throwing machine used for throwing ready-mixed concrete into the formwork, which is provided with a plurality of throwing ports at the bottom of the container body,
On the upper part of the charging port, a screwing transfer body of the same shaft having transfer blades to be transferred to each of the charging ports is arranged, and the transfer blade is rotated by rotating the shaft,
Therefore, the semi-solid material in the container body is guided to each of the charging ports and charged.

Furthermore, as a prior art published after the application of the present invention, there is one such as Japanese Utility Model Laid-Open No. 63-184942.
This one relates to a raw concrete bucket, an outlet is formed at the center of the bottom wall of the bucket, and one end of a screw conveyor arranged in the lateral direction is connected to this outlet, and A downward discharge port is opened at the end, and a predetermined amount of fresh concrete is discharged by rotationally driving the screw conveyor.

(Problems to be Solved by the Invention) However, in the concrete bucket disclosed in Japanese Patent Laid-Open No. 62-206168, which is the conventional example, the cylindrical discharge hoppers are integrally provided in the vertical direction. , The height of the whole including the bucket body and the discharge hopper becomes high, and there is a problem in the concrete supply to the bucket body when the concrete is put in or supplied to the bucket body when the factory has a low ceiling or the concrete mixer is in a low position. .

Further, this type of bucket is indispensable for cleaning work by removing concrete adhering after using it by means such as washing with water. Since the hopper discharge hopper is attached integrally, it cannot be cleaned while it is hung on the ground, and it is necessary to carry out the cleaning work while it is in the suspended state, and it is unstable and safe. However, since the screw is fitted in the cylindrical discharge hopper, the concrete adhering to the back side of the blade of the screw cannot be removed.

In addition, other conventional examples such as Japanese Utility Model Publication No. 62-78405, Japanese Utility Model Publication No. 58-1031, and Japanese Utility Model Publication No. 63-184942.
In each of the conventional examples described above, since the funnel-shaped concrete bucket itself is not disposed in a housed state in a framed suspension and a frame that can be installed on the ground, the one disclosed in Japanese Patent Publication No. And it is difficult to suspend and convey the hopper in a safe and stable state,
In particular, the hopper with a built-in screw could be easily damaged by coming into contact with other objects during work, and when not in use, it cannot be installed in a stable condition on the ground, so cleaning after use is not possible. There was a problem that work could not be done quickly in a safe state.

(Means for Solving Problems) An object of the present invention is to solve the above problems, and to form a substantially box-shaped or turret-shaped frame that can be hung and installed on the ground with a required number of columns and cross rails. The funnel-shaped bucket body is placed inside the frame, and the tubular hopper equipped with a screw is laterally integrally disposed at the bottom of the bucket body through the communication opening. A motor capable of selectively driving the screw is provided adjacent to the base side of the hopper while providing a discharge port on the tip side of the
Further, the motor is supported by an auxiliary column and a cross rail incorporated in the frame.

(Embodiment) Next, the present invention will be described in more detail with reference to an illustrated embodiment. Reference numeral 1 is a frame that is framed in a substantially box shape, and the frame includes four columns 1a arranged at each corner portion in the vertical direction. ,
It is composed of a plurality of horizontal crosspieces 1b arranged at the upper and lower parts between the columns, and is framed in the shape of a box or a turret as a whole and can be installed on the ground.

A funnel-shaped bucket main body 2 is integrally mounted in a housed state inside the frame 1 configured as described above, and a hopper 3 having a substantially cylindrical shape is laterally attached to the bottom of the bucket main body 2 via the communication opening 2a. Are arranged integrally with each other. In this case, the communication opening 2a between the bucket body 2 and the hopper 3 is
On the side of the base portion 3a of the hopper 3, the length of the hopper 3 is about half or more of the total length of the hopper so that concrete can be quickly supplied from the bucket body 2 to the hopper 3. A concrete discharge port 4 is provided on the tip 3b side of the hopper 3 arranged in this way, and a screw 5 is arranged inside the hopper along the length direction thereof. Three
It is adapted to be selectively driven by a motor 6 disposed adjacent to the base portion 3a side. The motor 6 is supported by an auxiliary column 7 and a horizontal rail 8 incorporated in the frame 1, and the screw 5 is driven by, for example, a chain or a V belt 9. In the drawing, reference numeral 10 is a supporting rod for suspension, which is provided so as to pass through the upper horizontal rail 1b, and 11 is a ladder.

(Operation) The concrete bucket configured as described above stores a predetermined amount of low-slump concrete in the bucket body 2, conveys it to the concrete pouring position in a suspended state, drives the motor 6 at the pouring position, By rotating the screw 5, concrete is transferred to the tip 3b side of the hopper 3, and concrete is sequentially discharged from the discharge port 4 and placed.

In this case, since the hopper 3 is located laterally,
Almost no leakage of concrete during transportation,
Further, since the communication opening 2a between the bucket body 2 and the hopper 3 is relatively wide, even the concrete with a low slump can be efficiently transferred to the tip 3b side of the hopper 3 by the screw 5, and thereby There is almost no unexposed concrete in the bucket body 2, and the waste of concrete is eliminated.

Further, even if the concrete pouring position is near the wall surface or the columnar object, since the concrete discharge port 4 is located on the tip 3b side of the hopper 3, another guide gutter or the like is not required, and the discharge port 4 is not required. Since the concrete can be directly supplied from the above to the pouring position and the bucket main body 2 and the hopper 3 are arranged in a housed state inside a frame framed in a box shape or a turret shape and the surroundings are protected by the frame, Work can be performed without being easily damaged by contact with an object.

Further, when the concrete bucket is cleaned after the concrete pouring work is finished, the bucket may be dropped on a flat ground and kept in a stable state, and water may be supplied from the bucket body 2 for cleaning. . In this case, since the communication opening 2a between the bucket body 2 and the hopper 3 is relatively wide, the concrete adhering to the screw 5 can be easily removed.

(Effects) As described above, according to the present invention, a storage box is funnel-shaped inside a frame that is framed in a substantially box shape or a turret shape so that it can be hung by the required number of columns and cross rails and installed on the ground. And a tubular hopper provided with a screw at the bottom of the bucket body is integrally disposed laterally through the communication opening, and a discharge port is provided at the tip end side of the hopper. Since a motor capable of selectively driving the screw is arranged adjacent to the base side of the hopper, and the motor is supported by auxiliary columns and cross rails incorporated in the frame, the bucket body Since the hopper and the hopper are hung by a required number of columns and cross rails and are arranged in a housed state in a frame framed in a substantially box shape or a turret shape so that they can be installed on the ground, the bucket body And the surroundings of the hopper will be protected by the framed frame, and during the concrete pouring work, the bucket body and the hopper will not be damaged by contact with other objects, and can be suspended safely and stably. It can be dropped and quickly transported to the concrete pouring place for pouring work, and when not in use it can be stably placed on the ground and also for cleaning work after use. Not only is it safe to clean while it is placed on the ground, it also has a motor for driving the screw installed inside the hopper, which is installed next to the base side of the hopper in the auxiliary column and sideways installed in the frame. By supporting it with a cross,
There are various effects such that the entire bucket can be made compact, the volume of the bucket main body and the hopper can be utilized to the maximum extent, and if the motor has a failure, it can be easily repaired.
