This soil-filling device has a soil-container transport mechanism including a chain conveyor and a soil-supply mechanism provided on the transport mechanism. Of these, the soil supply mechanism is a hopper capable of dropping and supplying a predetermined amount of soil, and a dispersal conveyor comprising a belt conveyor capable of transporting the soil from the hopper for a predetermined distance along the transport mechanism. With. In this way, the soil from the soil hopper is temporarily
By interfering with the dispersal conveyor, the soil dropped from the dispersal conveyor onto the transport mechanism can be balanced in the soil container.

[0003]

By the way, when the belt of the balance conveyor extends beyond the adjustable range, is damaged, or breaks, it is naturally necessary to replace it. However, in the conventional soil-filling device, the soil hopper and the dispersal conveyor are directly attached to the device frame that is integrally provided in the base frame portion of the transport mechanism to install the soil supply mechanism. There is.

Therefore, when carrying out the above belt replacement work, the worker disassembles the device frame and the hopper,
It must be carried out in an unnatural posture such that one leans over the transport mechanism, and with a hand inserted into a narrow space below the hopper in the equipment frame, while disassembling the conveyor. It was difficult to do, and the work time was long.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a soil-filling device which enables easy and quick belt exchange work.

[0006]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, according to the first aspect of the present invention, the soil supply unit is provided on the transport path of the soil container via the device frame, and the soil from the soil supply unit is provided between the soil supply unit and the transport path. Is provided in the soil-conveying device, which is provided with a pair of front and rear rollers, and an endless belt wound around both rollers, and the variety conveyor is a device It is characterized in that a pair of front and rear rollers are held at predetermined intervals by a conveyor frame independently formed with respect to the frame, and can be detachably attached to the apparatus frame together with the conveyor frame.

As described above, since the dispersal conveyor has its own conveyor frame, the conveyor frame can be attached to and detached from the apparatus frame integrated with the base frame portion of the transport path. Therefore, the belt exchanging work can be performed in a state where the dispersal conveyor is taken out from the apparatus frame, that is, a place separated from the lower side of the soil supply unit such as the hopper.

It is preferable that the apparatus frame is provided with a guide rail capable of supporting a part or all of the conveyor frame in the dispersive conveyor (claim 2).
With this configuration, the disassembly / disassembly of the conveyor can be performed along the guide rail, and the work is easy.
Moreover, the alignment can be performed accurately, reliably and quickly.

By the way, a structure may be adopted in which the drive device is provided for the conveyor frame of the dispersal conveyor, but in this structure the dispersal conveyor becomes heavy and becomes a burden of attachment and detachment work for the device frame. Therefore, it is preferable that the dispersal conveyor has a drive transmission unit that can be attached to and detached from at least one of the rollers in a state of being attached to the apparatus frame (claim 3).

That is, the drive device itself is provided on the device frame side, and a drive transmission portion for connecting the drive device and at least one roller is provided from the outside of the device frame (that is, the dispersive conveyor is provided on the device frame). If the structure is such that it can be attached to and detached from the bulk conveyor, the weight can be reduced when the bulk conveyor is attached and detached.
