DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical continuous unloader, and more particularly to an improvement in a mechanical continuous unloader capable of satisfactorily taking in and supplying a conveyed object to a vertical conveying means of the unloader.

[0002]

2. Description of the Related Art Generally, a mechanical continuous unloader is used for unloading powders and particulates loaded on a transport ship. This type of conventional unloader employs a method of loading and unloading a conveyed object 2 from a ship 1 by a mechanical continuous unloader 4 having a vertical conveying means 3 as shown in FIG. As shown in FIG. 2B, the vertical transport means 3 is provided with a high-level transporter 6 inside a cylindrical casing 5 and rotates around a vertical axis around a take-in port 7 provided at the lower end of the casing 5. It is provided with an impeller 8 to be driven,
The conveyed articles 2 are configured to be bounced off by the impeller 8 toward the hi-levelt of the conveyer 6 and sequentially conveyed.

[0003]

However, in the structure of the above-mentioned conventional mechanical continuous unloader, if the conveyed material 2 has poor flowability, the conveyed material 2 does not naturally flow into the impeller 8 and the conveyability is low. There is a disadvantage that it decreases. That is, if the transported material 2 has a property such as pulverized coal, it is compacted in a compacted state due to vibration or the like at the time of transportation by the ship 1 and has very poor fluidity. Without impeller 8
You have to break it yourself. Since the impeller 8 is basically used to bounce the powder having fluidity toward the conveyor 6, the impeller 8 cannot effectively exert the breaking action, and the inlet to the impeller 8 is small. For this reason, the compacted conveyed article 2 cannot be effectively taken inside.

[0004] It is an object of the present invention to provide a mechanical continuous unloader which eliminates the drawback of the above-mentioned conventional technology in which the capacity is reduced, and is capable of carrying out a conveyed product even in a compacted state with a stable carrying capacity. is there. Further, as another object, the compacted conveyed material is supplied to the impeller in a state where it is dispersed as much as possible in units of particles without being taken in a block state, so that the supply operation of the conveyer to the conveyer by the impeller is smoothly performed. An object of the present invention is to provide an unloader structure capable of improving efficiency. Further, it is another object of the present invention to provide an unloader that increases the carry-out amount of a conveyed object to a transfer device by using an impeller to exert a function of breaking down a conveyed object, thereby further improving efficiency.

[0005]

In order to achieve the above-mentioned object, a mechanical continuous unloader according to the present invention has a vertical transport means having a built-in leveler transporter, and takes in a conveyed material into the vertical transport means. The mouth is provided with an impeller that is rotatable about a horizontal axis and that bounces and supplies the conveyed object toward the vertical conveyor, and is disposed near the impeller and is capable of being driven to rotate horizontally to transfer the conveyed object to the impeller. A slicing means for scraping , the slicing means and the impeller
A chute that guides the conveyed material between
Was provided .

In this case , the breaking means has a claw that slides and rotates on the chute entrance opening surface, and the chute exit may be opened at a location different from the intake port of the impeller.

[0007]

According to the above construction, the cut-off means rotates in the same direction in any of the front, rear, left and right directions with respect to the transport means of the unloader, and comes into contact with the transported object. The impeller no longer supplies the conveyed material to the conveyor in a block state, and the rotation of the impeller is prevented from occurring, so that the unloading operation is performed smoothly. In addition, since the cut-off means is directly supplied to the impeller by supplying the cut-off conveyed material to the impeller through the chute, the fluidized conveyed material is directly conveyed by the impeller. Simultaneously with the supply to the machine, the impeller can perform the action of breaking down the compacted lump of transported material. Further, by sliding and rotating the claws of the cutting means at the inlet opening of the chute, the cut-off conveyed material is reliably prevented from dropping down in the chute in a block state. It can be supplied to a car and carried out, so that more efficient carrying out becomes possible.
