Description

  The present invention relates to an asphalt mixture conveying device for conveying and storing asphalt mixture used as a road pavement or the like with a conveyance bucket.

Conventionally, for example, an asphalt plant having the configuration shown in FIG. 8 is known. In this asphalt plant 1, a plurality of aggregate hoppers 2 in which sand and crushed stones are arranged according to particle sizes are arranged, and sand and crushed stones are conveyed from the aggregate hopper 2 to a dryer 4 via a belt conveyor 3, In the dryer 4, sand and crushed stone are burned by the burner 5 to dry the moisture. The dust generated by the combustion is collected through the back filter 6, and clean air from which the dust has been removed is exhausted from the chimney 6a.
The heated sand and crushed stone are stored in a transport bucket and transported upward by a hot elevator 8, put into a vibrating screen 9 from the transport bucket and separated into crushed stone and sand having different particle sizes, and then a hot bottle 10 for each particle size. Are dropped in the mixer 12 weighed with a measuring instrument.

  Then, the asphalt carried out from the asphalt tank 11 is measured with a measuring instrument and dropped onto the mixer 12, and the stone powder carried out from the stone powder tank 7 is measured with a measuring instrument and dropped onto the mixer 12. Thereby, an aggregate, asphalt, and a stone powder are mixed and an asphalt compound material is manufactured. The obtained asphalt mixture is dropped from the mixer 12 and loaded on a dump truck and sent out, or conveyed to a storage silo for asphalt mixture and stored.

  When the asphalt mixture produced in the above-described asphalt plant 1 is stored in the storage silo, for example, it is transported by the asphalt mixture transport device described in Patent Document 1 and stored in the storage silo. In this transport device, asphalt mixture is put into the transport bucket from the mixer 12 and stored, and after the transport bucket is lifted from the lower part to the upper part of the skip elevator, it is stored from the upper input port of the storage silo. Drop into the silo.

  Therefore, the skip elevator extends to the lower horizontal rail for introducing and transferring the asphalt mixture from the mixer to the transport bucket, the vertical rail along the height direction of the storage silo, and the upper input port of the storage silo. It has a guide rail formed in a substantially S shape with the upper horizontal rail. Then, the wire rope fed out from the electric winch installed on the gantry of the asphalt plant 1 is connected to the conveyance bucket, and the drive motor of the electric winch is rotated in the forward and reverse directions so that the conveyance bucket is substantially omitted via the wire rope. The asphalt mixture was transported by reciprocating along the S-shaped guide rail from the position of the mixer to the upper charging port of the storage silo and repeatedly transporting the transport bucket.
