Description

Description: TECHNICAL FIELD The present invention relates to a belt conveyor device used to transport a large amount of powder or granular material such as grain.

(Conventional technology) Conventionally, a belt conveyor has been used to transport grains and the like, and both edges of the belt are provided in a gutter-like shape so that grains do not fall down from side edges of the belt, and the articles are transported in this state. Was.

(Problems to be Solved by the Invention) However, in the conventional apparatus, there is a limit to the height of the side edge of the belt, so that a large amount of articles cannot be conveyed. The applicant has proposed a belt conveyor for mass transfer (Japanese Patent Application No. 1-2965). The present invention discloses that the belt is conveyed by inserting the conveying section through the inside of the cylindrical body. However, in the structure in which the conveying section is inserted through the cylindrical body, the cross-sectional shape of the belt between the cylindrical body outlet and the end of the conveying section is changed from an arc shape to a flat shape. At the exit, the grain overflows from the belt and falls down from its side edges. Therefore, even if the opening of the receiving hopper provided below the end of the conveying section is enlarged, the grains are scattered around.

An object of the present invention is to provide a belt conveyor having a structure capable of transporting a large amount of grains and the like in order to solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, a configuration of the present invention provides a belt conveyor device for inserting an endless transport belt made of a low friction member into a cylindrical body. A side regulating member having a side plate erected along the side edge of the endless transport belt is provided on the inside, the side regulating member is disposed on the endless transport belt, and one end of the side regulating member is provided. It is characterized in that a throttle portion for guiding the conveyed article toward the center is provided, and the other end where the throttle portion is not provided protrudes from the cylinder toward the discharge portion side of the cylinder.

(Operation) In the present invention, the grain conveyed in the cylinder is conveyed so as to be brought closer to the center by the throttle portion of the side regulating member near the discharge portion, and is regulated on the conveyor belt coming out of the cylinder. Since the transported material is brought inside the side plate of the member, and the lower end of the side plate and the transport belt are close to each other,
Conveyance hardly falls from between the two.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS.

As shown in FIGS. 1 and 2, an endless annular transport belt B is stretched between a pair of pulleys 1 and 1 (one side is shown), and an intermediate portion on the transport section side is covered with a cylindrical body 2. ing. The transport belt B has a low-friction cloth adhered to its inner surface or processed to reduce the friction coefficient, and is in contact with the lower inner peripheral surface inside the cylindrical body. The end of the conveyor section of the conveyor belt B is a pulley 1
And the return portion is hung on the return roller 3. A side restricting member 4 having a substantially U-shaped cross section and having a downward opening is inserted into the opening of the cylindrical body 2 on the discharge portion side. .

The side regulating member 4 is formed of an iron plate such as a steel plate, and has a mounting hole 6 in the ceiling 4a as shown in FIG. Side plates 4b are formed by bending downward from both ends of the ceiling portion 4a, and arc-shaped reinforcing members 7 are welded to the fold portions so as to conform to the inner peripheral surface of the cylinder. A guide piece 4c bent outward is formed at the insertion side end 8 of the side plate 4b, and a lower portion 4d from the insertion side end 8 of the side plate 4b is bent obliquely toward the center to form the guide piece 4c and the side plate 4b. The lower portion 4d gradually narrows the space between the side plates 4b, 4b to form a narrowed portion. Lower part of side plate 4b
4d has a notch 9 at an appropriate distance, a gap is formed between the hanging side plate 4b, and the notch 9 and the discharge side end 10 of the side plate 4b.
The lower part 4e of the section is bent inward and the lower end is extended from above so as to approach the transport belt. It should be noted that the throttle section and the cutout section 9 may be provided in two or three stages.

In the conveyor belt configured as described above, as shown in FIG. 4, when the grain W is fed up to the upper side of the conveyor belt B inside the cylindrical body 2, it is guided to the guide piece 4c in the middle of the conveyance, as shown in FIG. The grain W moves to the center of the cylindrical body 2 and the grain W is pushed up into the space above. Next, when the sheet is conveyed to the vicinity of the notch 9, as shown in FIG.
Even if a part of the grain W that has been carried in enters between them, as shown by arrows shown in FIG. Cereal W hardly flows between the side plate 4e and the cylinder 2. Further, in the portion exposed from the cylindrical body 2, as shown in FIG.
And the side edge of the conveyor belt B is slightly
Only the overflow from the lower part 4e of 4b is carried.

(Effect of the Invention) Since the present invention is configured as described above, the conveyed material flows through the center of the conveyer belt by the side regulating member, and prevents the conveyed material from dropping laterally when it comes out of the cylindrical body. Since no load is applied to the edge of the conveyor belt when it comes out of the cylindrical body, the equipment cost can be reduced without installing a carrier roller for supporting the side surface which has been conventionally used.
