The projecting body 107 preferably has a hollow cross section as in the present embodiment so as to be easily deformed and closely contact with the skirt rubber 32, but may be solid, and its shape is particularly limited. It is not something.

  Next, the operation of the fluid transport apparatus 1 having the above configuration will be described. First, as shown in FIG. 1, the fluid conveyance device 1 is installed on the ground G. The height of the chute 3 can be appropriately adjusted to the height of the device used in the next process by adjusting the length of the leg 5 corresponding to this. Thereafter, a vehicle 50 such as a dump truck is mounted on the inclined platform 51 installed in the vicinity of the hopper 2, and the fluid loaded on the loading platform is put into the hopper 2. The fluid to be charged is not particularly limited as long as it has fluidity such as a granular material, a powdery material, a liquid material, a gelled material, specifically, biomass fuel such as coal and wood chips, limestone, Examples include sludge, clinker, incombustible waste, and aggregate. The introduction of the fluid into the hopper 2 may be performed using a truck damper or the like instead of performing the operation of the vehicle 50 itself.

  The fluid charged in the hopper 2 is mounted on the transport surface 10a of the transport conveyor 10, and is transported upward in a state in which both sides in the width direction of the transport surface 10a are guarded by the skirt member 30. Discharged from. In order to adjust the flow rate of the fluid discharged from the chute 3, as shown in FIG. 7, a leveling member 40 is provided between the left and right side plates 22 and 22 in the vicinity of the chute 3 so as to be movable up and down. Alternatively, the amount of fluid F discharged from the chute 3 can be adjusted by changing the size of the gap between the transport surface and the leveling member 40.

  On the other hand, a part of the fluid that remains attached to the conveying surface 10a falls on the receiving surface 20a of the receiving member 20 while passing through the drive shaft 11 and being conveyed with the conveying surface 10a facing downward. Carry back may occur. Conventionally, if such a carry-back is left unattended, the amount of fluid deposits below the conveyor 10 increases, which may cause malfunction, and thus a complicated operation for cleaning the entire receiving surface 20a is required. It was.

  In contrast, the fluid conveyance device 1 of the present embodiment can scrape the fluid adhering to the receiving surface 20a by the scraping member 13 provided on the conveyance surface 10a and convey it toward the driven shaft 12. Therefore, even when the receiving surface 20a is cleaned, it is only necessary to clean the vicinity of the driven shaft 12 that is the inlet portion of the receiving member 20, and the cleaning work can be facilitated. If the distance between the scraping members 13 arranged on the transport surface 10a is too large, the number of scrapes of the receiving surface 20a is reduced and it becomes difficult to transport the attached fluid. Since the amount of animals increases, it is preferable to set to about 2 to 3 m.

  Further, the conveyor 10 is arranged such that the guide surface 123a of the cover member 123 covering the folded portion R of the conveyance surface 10a is continuous with the receiving surface 20a, and the tip of the scraping member 13 is the guide of the cover member 123. Since the surface 123a is scraped off, the fluid collected in the vicinity of the turn-back portion R by scraping and transporting the receiving surface 20a is pushed up along the guide surface 123a by the scraping member 13 and is then moved into the hopper. 2 passes under 2 and is conveyed again toward the chute 3. Such a fluid auto-return function further reduces the cleaning work, and can more easily suppress the accumulation of fluid under the conveyor 10.

  The conveyor 10 includes a belt-like body 104 on which the sliding portion 32 a of the skirt member 30 slides, and a protrusion 107 that protrudes from the belt-like body 104 and contacts the skirt member 30. Since the protrusion 107 is made of a material that is more easily worn than the sliding portion 32a of the skirt member 30, the wear of the sliding portion 32a can be suppressed and the durability of the skirt member 30 can be improved. When the belt-like body 104 and the projecting body 107 are greatly worn, they can be easily replaced.
