Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cement handling apparatus for measuring the amount of cement in a conveyed cement bag and for easily supplying the cement bag to a construction site.

[0002]

2. Description of the Related Art As is well known, a relatively large amount of cement used in a bag is used, for example, in a ground improvement method or a slope spraying method. It is very heavy because it is traded in units, and unloading from trucks at construction sites requires handling equipment. Regardless of the ground improvement or spraying method, for example, a processing device such as a mixer has a limited capacity, so that a device for storing, for example, about 1 ton of cement and extracting an appropriate amount is required.

However, according to the prior art, 50 k
Although a cement bag as small as g could be handled, a large amount of cement bag could not be handled.

Although it is desired to accurately measure the amount of cement supplied at the same time, conventionally, only an operation equivalent to the total number of cement bags could be performed.

[0005]

Accordingly, it is an object of the present invention to provide a cement handling apparatus which can handle a relatively large amount of cement at a time.

Another object of the present invention is to provide a cement handling apparatus which can relatively easily measure the weight of cement to be handled and can be easily supplied to the next processing apparatus.

It is another object of the present invention to provide a cement handling apparatus that can be easily installed on site and is easy to handle.

[0008]

According to the present invention, there is provided a cement handling apparatus for measuring the amount of cement in a transported cement bag and for easily supplying the cement to a construction site.
A base frame of a rectangular frame-shaped frame installed horizontally on the ground, an upper frame of a square box frame-shaped frame without a bottom mounted on the upper portion of the base frame, and a horizontal frame provided at the upper center of the upper frame. A rail having one end protruding outward from the upper gantry, an electric lifting device mounted so as to be guided and moved by the rail, and a cement provided on the base gantry via a support to convey cement to the outside. It comprises an electric transport device and a weighing hopper having a weighing device, and is configured so that the cement lifted at the outwardly projecting portion of the rail moves to the upper portion of the weighing hopper and is charged.

Therefore, for example, a cement bag carried by a truck or the like is conveyed above the weighing hopper by an electric lifting device below the outwardly protruding rail, and then broken to break the cement into the weighing hopper. throw into. The cement thus introduced into the weighing hopper is weighed, and the required amount of the cement is sent to the outside by the transport device.
