Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a belt conveyor used for conveying grain, flour, earth and sand, etc., in which a conveyor belt is supported by something other than a carrier roller. Regarding conveyor equipment.

(Prior Art) Conventionally, belt conveyors have been used to transport grain, earth and sand, etc. The conveyance section side of the belt conveyor is supported by a carrier roller that can be mounted horizontally or at an angle on the frame, and is provided so that the belt can easily move during conveyance. In addition, in order to remove the dust generated during the transportation of grain, etc., a dust removing device, a cover, etc., were installed to absorb the dust, so that the dust would not scatter and the interior of the room would be prevented from becoming dirty. FIG. 4 shows an example of this, in which a conveying device 3 is provided in which the conveying section side of the belt 1 is covered with a cylinder 2, an input port 4 is attached at an appropriate location, and a carrier is provided at the outlet of the cylinder 2. Rollers 5 and 6 are arranged. As shown in FIG. 5, carrier rollers 5 and 6 are rotatably attached to support members 7 and 8, and the positions of the left and right carrier rollers can be adjusted relatively back and forth. In addition, the pitch P between the carrier roller 5 and the carrier roller 6 is set at 50 mm due to load and tension considerations.
It is installed at a height of ~120cm.

(Problem to be Solved by the Invention) However, the carrier rollers 5 and 6 must be installed with a structure that can withstand the load of conveyed objects and have a small coefficient of friction, so they are very expensive and must be installed with precision. It takes. Furthermore, if the support shafts of the carrier rollers 5, 6, etc. become dirty with dust, their rotational operation becomes poor, requiring a large driving force during conveyance, and maintenance work becomes complicated.

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, it is an object of the present invention to provide an improved grain conveying device in which the belt is supported by a separate support member without rotating parts.

(Means for Solving the Problems) In order to achieve the object described above, the present invention has a structure in which an endless annular conveyor belt whose inner surface is made of a low-friction material is stretched between a pair of belt wheels. , the conveyor side of the conveyor belt,
It is characterized by being supported from below by steel plates at appropriate intervals.

Furthermore, an endless annular conveyor belt whose inner surface is made of a low-friction material is stretched between the pair of belt wheels, and the conveyor belt side of the conveyor belt is supported from below by steel plates at appropriate intervals. The middle part of the side is inserted into the inside of the cylindrical body, and the middle part is supported by the lower inner circumferential surface of the cylindrical body.

(Function) Since the present invention is constructed as shown in -1- below, the inner surface of the conveying portion of the conveyor belt comes into contact with the steel plate and the inner circumferential surface of the cylinder, and slides against each other during conveyance. When a conveyed object is placed on the conveying section, the driving force of the conveyor belt increases due to its weight, but since it is a low-friction member, even if it makes surface contact with a steel plate, the frictional force is small and it can be easily conveyed. Further, when the dust is transported inside the cylinder, the dust simply floats inside the cylinder and can be transported without leaking to the outside.

(Example) An example of the present invention will be described based on FIGS. 1 to 3.

As shown in FIG. 1, an endless annular conveyor belt 1-B is stretched between a pair of belt pulleys 9 (one side is shown), and the intermediate portion on the side of the conveyor section is covered with a cylinder 10. To install the endless annular conveyor belt (H), after assembling each part, a plate-shaped conveyor belt is wound and the ends are connected or welded with adhesive. Further, in the conveyor bell I-B, a core material supporting the load is covered with rubber layers on both sides, and a low-friction cloth is adhered to the inner surface 11 of the core material. The inner surface 11 may be directly processed to reduce the coefficient of friction.

Further, as shown in FIG. 2, iron plates 13 fixed to support frames 12 are arranged at appropriate intervals at both ends of the cylinder 10 in the longitudinal direction of the conveyor belt B. It is attached to the frame 12 so as to be inclined from both side edges of the conveyor belt B toward the center, or to be positioned horizontally. The conveying section located outside the cylindrical body 10 of the conveying belt B has its inner surface 11 supported by an iron plate 13 from below.

The cylindrical body 10 has a flange 14 formed at its end, and has holes 16 for attaching bolts 15, so that a plurality of bolts 15 can be connected and adjusted to a suitable length. Furthermore, as shown in FIG. 3, if the cylinder body 10 is divided in the axial direction,
In addition to being easy to assemble, the second part 10a can be removed to inspect the interior, and a new input port can be easily created. The conveyor belt B is supported with its inner surface 11 in surface contact with the lower inner circumferential surface of the cylindrical body 10.

Further, a roller 17 is rotatably provided below the cylindrical body 10, and the return portion side of the conveyor belt B is hung thereon. The cylindrical body 10 may be attached to a frame (not shown) using the flanges 14 at both ends, and the discharge port may be attached to the casing 1.
8 may be enclosed to isolate it from the outside.

With this configuration, the conveying section side of the conveying bell L-H is always in surface contact with the iron plate 13 and/or the cylinder 10, but since the frictional force is small, the driving force of the belt pulley 9 can be reduced. Since the dust is transferred inside the cylindrical body 10, the dust generated within the cylindrical body 10 is trapped and prevented from scattering into the air.

In addition, if the iron plate 13 is fixed with a curvature, the conveyor belt B
This is preferable because the surface in contact with is large. Moreover, if the width of the iron plates 13 in the conveyance direction is increased, the strength of the conveyor belt B may be small, and the pitch between the iron plates 13 can be widened.

(Effects of the Invention) Since the present invention is configured as described below, the cost can be reduced by eliminating the carrier roller;
Since the load of the conveyed object is received on a flat surface, there is no sagging, and the strength of the belt I can be reduced, and the belt can be conveyed with 1/10 to 1/6 of the tension compared to a belt using a conventional carrier roller. Therefore, the driving source can be made smaller. Further, the steel plate is easy to assemble by simply fixing it to the support member, and can be attached extremely easily.

Furthermore, since the object is transferred inside the cylindrical body, there is no scattering of dust into the air during transportation, and no dust is mixed in from the outside, so the object can be transferred as is. For example, reliability can be improved when transporting toxic substances, medicines, food products, etc. Furthermore, since it is isolated from the outside, it has a soundproofing effect.
