Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a loader device for collecting heated and cut asphalt mixture using a bucket conveyor.

[Conventional technology]

As shown in FIG. 3, the bucket 01 of the loader device C is rotated and moved forward in the direction of the arrow to collect the asphalt mixture 02 into the container 03. In order to prevent asphalt from adhering to the bucket 01, light oil is periodically sprayed toward the bucket 01 from a light oil spraying device 04.

[Problems to be solved by the invention] The conventional equipment described above is not equipped with a heating device, and the temperature of the asphalt mixture during recovery is large.Also, even when light oil etc. is sprayed, the bucket part and the mixture are not heated. There is a lot of mixture adhering to the passage part, the collection efficiency is poor, and a large amount of power is required for collection. Even if measures are taken to prevent adhesion to the bucket part, the effect is not sufficient.

Further, there is a problem that the sprayed light oil or the like may mix into the asphalt mixture, causing harmful effects.

[Means for solving problems]

A heating device is installed in the bucket section and the mixture passage section to prevent the temperature inside the bucket conveyor from decreasing.

[Function] Since the bucket part and the mixture passing part are heated, the adhesion of the mixture to the corresponding parts is eliminated.

The temperature drop of the mixture during recovery can be suppressed as much as possible.

The indirectly heated asphalt acts as a lubricant and causes less wear on the parts that come into contact with the mixture.

[Example] An example according to this invention will be described with reference to FIG.

The loader device A includes a bucket 2 that takes in an asphalt mixture 8, a conveyor chain to which the bucket 2 is attached, a loader floor plate 6 that prevents the mixture 8 from dispersing from the bucket 2, and a heating device that heats the bucket 2 and the mixture 8. Consists of 1st class. The asphalt mixture 8 sent from the front of the loader device A is scooped up by a bucket 2 heated by the heating device 1, and conveyed upward while being sandwiched between the loader floor plate 6 and the rear end of the loader floor plate 6. It is discharged under its own weight.

As explained above, since the asphalt mixture 8 is transported while always being in contact with heated parts,
There is no adhesion of the asphalt mixture to the bucket 2 of the conveyor chain 3 and the asphalt mixture passage between the loader bottom plate 6 and the conveyor chain 3, making it possible to transport with a small amount of power.

FIG. 2 shows another embodiment of the present invention, in which the loader device B includes a cover 12 that covers the chain conveyor 11, and hot air inlet pipes 13 and 14 that introduce hot air into the cover 12.

According to this apparatus, the chain conveyor 11 and the asphalt mixture 8 can be mutually heated over a wide range.

[Effects of the invention] Since the parts that are always in contact with the asphalt mixture are heated to a temperature that prevents the mixture from adhering, the asphalt mixture is kept in the bucket of the conveyor chain and in the asphalt mixture passage section between the loader bottom plate and the conveyor chain. There is no adhesion, and the asphalt mixture can be completely discharged at the rear end of the loader floor plate, resulting in high recovery efficiency and low power requirements.

Since the heated asphalt acts as a lubricant, there is less wear on the mixture passage section.

There is no need to clean buckets, etc. at the end of work.
