Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the invention] Industrial field of application The present invention relates to a concrete bucket provided with a screw for forcibly discharging concrete.

BACKGROUND ART Conventionally, there has been a concrete placing apparatus in which a concrete input port is provided at the upper part of a pipe into which a screw is inserted, and a concrete discharge port is provided at the lower end of the pipe.

Problems to be Solved by the Invention However, the above-mentioned concrete placing device has the following problems:
Although there is a concrete inlet at the top of the pipe, it is impossible to temporarily store concrete in this inlet, so it cannot be used at sites where the concrete receiving and pouring areas are far apart. There was a problem. The present invention was made in order to solve these conventional problems, and its purpose is to enable concrete to be moved to the pouring site while it is being stored, and to improve the quality of concrete. To provide a concrete bucket with a screw which can improve construction efficiency by arbitrarily selecting a receiving place and a casting place for discharging using a screw.

[Structure of the Invention] Means for Solving the Problems The concrete bucket with a screw according to the present invention comprises: a bucket main body for storing concrete; a screw vertically disposed in at least a lower discharge port of the bucket main body; It is characterized in that it is composed of a screw drive device that rotates and is characterized in that the amount of concrete discharged is controlled by changing the rotational speed of this screw.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, 1 is the bucket main body,
A hanging means 1a is provided on the upper part.

The lower part of the bucket main body 1 is formed to be inclined in the shape of a funnel, and a discharge hopper 2 is provided in the center thereof.

A screw 3 is inserted into the discharge hopper 2 from above.
is installed vertically, and the upper end of its rotation shaft 3a is connected to a rotation drive shaft 4a of a drive device 4. The drive device 4 is connected to the bucket main body 1 via the frame 5.
installed on.

Incidentally, a chute 6 is attached to the bucket main body 1 as required, and the screw 3 is also extended and connected therewith.

To attach the chute 6, for example, as shown in FIG. At the same time, the screw 3 is also integrally connected by inserting the pin 8 into the hole 3a' of the rotating shaft 3a.

These chute 6 and the screw 3 housed therein have a fixed length, and can be extended to a required length by connecting them one after another in the manner described above, depending on the driving height.

[Effects of the Invention] (1) The bucket main body constituting the concrete bucket of the present invention has a bottom plate that slopes gently into a funnel shape and has a discharge port in the center, and a bottom plate that rises almost vertically from the periphery of the bottom plate. Since it is composed of a side plate with ivy and a hanging means provided on the top of the side plate, it can be moved to the pouring site while containing concrete, and the concrete receiving place and screw screw can be placed. The placement location for use and discharge can be arbitrarily selected.

(2) Since the chute can be detachably attached, effective pouring can be performed even if the pouring height changes.
