Abstract

(57) [Summary] [Purpose] Even if a small amount of concrete is ordered to a ready-mixed concrete plant in small-scale construction, it is often not transported due to lack of manpower. As a measure against this, the purpose is to provide a container for picking up concrete by truck. [Structure] The bottom of a doghouse with a pentagonal cross section was removed, and the ridge line corresponding to the ridge of the tank that was turned upside down was rounded to form a casing for a screw conveyor. Then, fix the pulley on one shaft end and drive it with a motor, open a hole with a lid larger than the screw on the other end, attach a freely foldable outflow gutter, and make a slope so that the outflow port goes down to the frame. Incorporate. A water tank for cleaning and a pump are also incorporated in the frame.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container for carrying a small amount of concrete on a truck while stirring so as not to cause separation and sedimentation.

[0002]

[Background of device]

 Recently, ready-mixed concrete mixing factories called ready-mixed plants have been established in various places, and most of the concrete for construction has a convenient system that can be delivered to the site with a single telephone, which played a part in the development of Japan. However, due to the current recession and lack of manpower, that situation is changing. For small orders such as 0.5 to 0.75 m, which is required for small construction, the raw plant cannot handle the transportation to the site due to lack of manpower and unprofitable transportation. is there. However, since there is no small mixer car on the side of the construction company, it is inefficient, but it will be necessary to purchase cement, gravel, and sand and carry out the mixing work manually. However, manually mixing 0.5 to 0.75 m of concrete requires considerable labor.

On the other hand, it has been practiced to use a small portable mixer to let the machine perform only the mixing work, but even then, it is necessary to collect the materials, and the operation of the mixer requires a little labor and is normal. It is a logical reason that it costs some money. Ultimately, it would be most reasonable for the contractor to purchase concrete from the ready-mixed plant in his truck and container. However, the problem remains in this case as well. That is, when concrete is put in an ordinary container and put on a truck and rocked, gravel and sand settle and water separates into an upper layer. Also, removing concrete from the container is not an easy task.

[0004]

[Problems to be solved by the device]

 The present invention is a container that can be carried on a truck.It receives concrete from a ready-mixed plant and does not cause sedimentation or separation during transportation. The purpose is to provide a concrete container that can be used.

[0005]

[Means for Solving the Problems]

 The present invention removes the base of a pentagon that represents the shape of a house, closes both ends of a container whose cross-section is upside down with flats, and at the bottom of the container a screw conveyor in the length direction of the container. The shape of the casing is used, the rotary screw shaft is installed in it, and a pulley is attached to the shaft end that penetrates one end face to drive with an electric motor or engine, and the bearing is attached to the other end face penetrating part. In addition, a circular hole with a lid that serves as a concrete outlet is provided around it, and a concrete outflow gutter is installed. In addition, the bottom of the container will be laid out so that the outlet will be low to facilitate concrete outflow, and a water tank with a motor pump will be installed to clean the container after use.

[0006]

[Action]

 It is sufficient to prepare a concrete container of the present invention with a maximum capacity of about 2 tons, but even if it is placed on a truck, the concrete receiving port on the upper surface has a large difference in height from the concrete outlet of the ready-mixed plant. The upper surface of the container should be fully open. The screw shall be rotated at all times as long as the concrete is in the container, and when the motor is operating, the power source is 12V of the truck's storage battery. In addition, the concrete outlet lid and the gutter are operated manually. The electric pump of the water tank also uses the storage battery of the truck, and the water can be used not only for washing but also for adjusting the amount of water in the concrete, which is very convenient especially when there is no water at the construction site. Since the truck can be small, it can pass on narrow roads, which may be more advantageous than carrying a mixer truck. In addition, since the container is small, it can be lifted by a crane and extended to the work place at a high place by extending the power line, and in some cases the concrete pump of the mixer truck is not required.

【Example】

 1 is a side sectional view of a concrete carrier according to the present invention, and FIG. 2 is a front view thereof. A frame 1 supports a concrete container 2. The container 2 is shaped like an upside down kennel, and the cross section of the portion corresponding to the ridgeline of the roof part is molded into an arc, and the screw conveyor 3 is configured through the screw transport 3. Both ends of the container 2 are closed by a flat plate, but the shaft end of the screw shaft 3 passes through the bearing 5 and penetrates one end face, and the belt pulley 6 is attached to rotate the shaft 2 by the reduction motor 7. The deceleration motor 7 is driven by the storage battery of the truck.

A bearing 5 is attached to the penetrating portion of the other end surface of the screw shaft 3, an outflow hole 9 with a lid 8 serving as a concrete outlet is provided around the bearing 5, and a concrete outflow trough 10 is attached. The screw conveyor 4 is attached to the frame 1 with a gradient so that the side of the outflow hole 9 faces downward. A pulling string 11 is connected to the concrete outflow gutter 10, and when the knob 12 at the other end is pulled down, the outflow gutter 10 is pulled up by a pulley 13. The lid 8 is slidably opened and closed by a handle 15 around a fulcrum 14, and when closed, is pressed against an outflow hole 9 by a spring 16 to prevent leakage of concrete.

A water tank 17 is provided under the reduction motor 7 on the other end surface side of the screw shaft 3, and a pump 18 with a small motor connected to a truck storage battery is connected to the water tank 17. The water can be used for adjusting the concrete water volume, for cleaning containers and others, and for general construction. A hook ring 19 is fixed to the frame 1 and can be transported to a high place by a crane. It can flow out as it is, but in order to rotate the screw shaft 3, it is necessary to connect to 12V.

[0009]

[Effect of device]

 Even if a small amount of concrete is ordered from a ready-mixed plant, it is often not transported. Small and medium builders are having a hard time with this, but there was no good idea. The present invention solves this problem by adding a container equipped with a mechanism for rotating the screw shaft at the bottom to prevent the concrete from settling and separating and being convenient for spillage to be used as a small truck. By picking it up and going to the ready-mixed plant, you can freely pass through narrow passages to the site, and you can perform concrete pouring work at a high position with a crane without using a concrete pump that takes up space. I got it.
