Abstract

PURPOSE:To easily place concrete by providing a hopper provided with a screw to the bottom of a bucket fixed to the inside of a frame through a connected opening as a unit widthwise and providing a discharge port to the top of the hopper. CONSTITUTION:A specific amount of low slump concrete is housed into a bucket body 2 placed to the inside of a frame 1, and it is carried to a place to place the concrete in a state of hanging. After that, a motor 6 is driven to rotate a screw provided to the inside of a hopper 3, and the bucket body 2 is moved to the tip 3b of the concrete hopper 3 to discharge the concrete subsequently from a discharge port 4 for placing the concrete.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field 1) The present invention relates to a concrete bucket used for placing low slump concrete.

[Prior Art 1] Generally, in concrete pouring, a concrete pump or a concrete bucket is used as a means for conveying concrete to a pouring position. Considering its performance, the concrete pump can only convey concrete with high fluidity, so-called high slump concrete that has a high cement amount and moisture, and is able to transport concrete with low fluidity and low slump, which is desired in this type of industry. Not suitable for transporting concrete.

Therefore, concrete buckets of various structures have been proposed for conveying low slump concrete. For example, the configuration disclosed in Japanese Unexamined Patent Publication No. 62-206168 is well known as a conventional example. This conventional concrete bucket consists of a cylindrical discharge hopper that is vertically connected to the center of the bottom of the bucket body, and a screw that is rotatably disposed inside the discharge hopper. A predetermined amount of concrete is discharged by rotating the screw.

[Problems to be Solved by the Invention] In the conventional examples of concrete 1 to 45, the cylindrical extraction hopper is integrally connected in the vertical direction. When the overall height including bucket 1--main body = 1 concrete is charged or supplied, there is a problem with the concrete supply when Otsuki's Tsl is low or the concrete mixer is at a low position.

In addition, after using these buckets 1~, it is essential to perform cleaning work to remove the concrete 1~ by washing with water or the like, but in the conventional example, the buckets 1~
A cylindrical discharge hopper of a predetermined length is installed vertically at the bottom of the main body.Since it is installed on the bottom of the main body, there is no damage when cleaning it when it is lowered to the ground. It is unstable and unsafe, and because the screw is fitted inside the cylindrical υ outlet hole, the screw is inserted into the cylindrical pot for cleaning. There is also the problem that the concrete that is being served is not completely removed.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention disposes a bucket 1 to a main body in the shape of a funnel inside a frame constructed in a substantially box shape or turret shape. 1 - A cylindrical hopper equipped with a screw at the bottom of the main body is integrally arranged in the horizontal direction through the communicating part [1 part], and a discharge port is provided at the tip side of the hopper. The hopper is installed laterally, which lowers the overall height, and the bucket 1-body and 1\jar-
This will allow for even more space between the two parts.

[Example 1] Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 1 denotes a frame constructed in a substantially box shape, and the frame has four pillars arranged at each corner in the vertical direction. 1a, and multiple horizontal bars 1 arranged at the upper and lower parts between each support.
b, and is framed in the shape of a lead or a turret as a whole.

A funnel-shaped bucket 1 to a main body 2 are integrally attached to the inside of the frame 1 configured as described above, and a substantially cylindrical hopper 3 is attached to the bottom of the bucket 1 to the main body 2 through a communication opening 2.
are integrally arranged laterally via a. In this case, the communication opening 2a between the bucket main body 2 and the small brim 3 extends over approximately half of the total length of the small brim on the base 3a side of the hopper 3. This is to ensure that concrete is quickly supplied to the area. The tip 3b of the hopper 3 arranged in this way
Discharge ports 4 for concrete 1 to 4 are provided on the side, and a screw 5 is provided inside the hopper along its length, and the screw is attached to the base 3a side of the hopper 3. The motor 6 is selectively driven by a motor 6 disposed adjacent to the frame 1. The drive is performed, for example, through a bell 1 or a bell 9. In the figure, reference numeral 1
0 is a support rod for the hanging wheel, which is provided through the upper horizontal bar 1b, and 11 is a ladder.

The concrete bucket configured in this way is = 5
- Store a predetermined amount of low slump concrete 1~ in the bucket body 2, transport it in a suspended state to the concrete pouring position, drive the 83C motor 6 to the concrete pouring position, and drive the screw 5.
By rotating the concrete 1 to 3, the concrete 1 is transferred to the tip 3b of the hopper 3, and the concrete 1 is sequentially discharged from the discharge port 4 for pouring.

In this case, since the hopper 3 is located in the horizontal direction,
There is almost no leakage of concrete during conveyance, and since the communication opening 2a between the bucket body 2 and the hopper 3 is relatively wide, even concrete with low slump can be efficiently transferred to the hopper by the screw 5. As a result, there is almost no unfilled concrete in the bucket body 2, and no concrete is wasted.

In addition, even if the concrete placement position is near a wall surface or a columnar object, since the discharge port 4 of the concrete 1 is located on the tip 3b side of the hopper 3, no other guide gutter etc. is required. Concrete can be directly supplied from the discharge port 4 to the pouring position.

Furthermore, when cleaning the concrete 1~packet after concrete placement work is completed, the bucket is lowered onto flat ground, kept in a stable state, and water is supplied from the bucket body 2. All you have to do is clean it. In this case, since the communication openings 2a between the bucket main body 2 and the hopper 3 are relatively wide open, the concrete 1 adhering to the screw 5 can be easily removed.

[Effect 1] As explained above, according to the present invention, a funnel-shaped bucket body is disposed inside a frame that is framed in a substantially box shape or a seed shape, and a cylinder equipped with a screw at the bottom of the bucket 1 to the body is provided. By arranging a shaped hopper in a horizontal direction through a communication opening and covering it with a configuration in which a discharge port is provided at the tip end of the hopper, the height of the entire concrete bucket can be significantly lowered. As a result, even in a concrete mixer or a factory with a low ceiling, concrete can be easily poured into the bucket body, which is an excellent effect.

In addition, since the bucket body and hopper are arranged within the assembled frame, it can be placed stably on the ground when not in use, and it is also easy to clean after use. Not only can cleaning be done while the bucket is on the ground, which is very safe, but the communication opening between the bucket body and the hopper is wide, and most of the screw is exposed in this communication opening, so the back side of the screw can be cleaned easily. It also has various excellent effects such as being able to easily clean the sides.

Furthermore, since the hopper is located horizontally, there is not only little leakage of concrete when transporting the concrete to the pouring position after storing it in the bucket body, but also preventing concrete from pouring. In J3, the communication opening is wide open, so even low-slump concrete can be properly transferred to the discharge port, and there is almost no unfilled concrete in the bucket body or hopper.
It also has the excellent effect of eliminating wasted concrete.
