Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a mobile batcher plant, more specifically a batcher plant, which is installed near the pouring point and raised as concrete is poured one layer at a time, so that it can be used for intermittent transportation of concrete, etc. The present invention relates to a mobile batcher plant that can reduce the amount of work done and improve the pouring capacity.

Conventionally, a batcher plant, which is a concrete mixing device, is fixedly installed at the top of a dam site a, as shown in Fig. 1, and a batcher plant b is a concrete mixing device.
concrete to the transfer car c, which travels along the bunker line d and stops at a predetermined position, and the cable crane e
Concrete is poured into a concrete bucket f which is placed in a suspended state, and the cable crane e lifts up the concrete bucket f and pours concrete into a concrete hopper g provided near the pouring point. Appropriate concrete is cut out from the concrete hopper g and transported to any desired dam placement site using a dump truck h.

Therefore, for transporting concrete, transfer car c, bunker line d, cable crane e,
It requires a lot of equipment such as a concrete hopper (g), which increases equipment costs, and since the concrete is transported via a transfer car (c) and a cable crane (e), the work is not continuous but intermittent. (b) The number of times the concrete is transferred between the pouring sites increases, and this, combined with the long transportation distance, has the disadvantage that the cycle time becomes longer or longer.

In addition, as shown in Fig. 2, instead of using a cable crane, an incline k is run by an incline winch j on an incline station running path i laid from a dam site a to a dam bottom n.
is installed, concrete is poured into the incline k from the transfer car c, and the incline k is
There is also one in which the concrete is lowered to a station m equipped with a hopper l provided at the dam bottom n, and the concrete is appropriately cut out from the station m.

However, in this case as well, as in the conventional example, a large amount of equipment is required, transportation work is intermittent, and the number of deliveries increases, resulting in a long cycle time.

The present invention eliminates the drawbacks of the conventional example and simplifies the equipment by providing a batcher plant that can be raised near the pouring point, continuously supplies concrete, and reduces the cycle time of concrete transportation. The purpose of this project is to provide a mobile batcher plant with high pouring capacity that can reduce the number of concrete placements. A belt conveyor and a cement conveying pipe are provided that extend from a raw material supply base storing raw materials toward the upper end of the frame, and the batcher plant and the end of the belt conveyor are connected via a splittable cylindrical aggregate input tower.
