DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a pipe conveyor provided with a hopper according to the present invention will be described below with reference to the drawings.
The hopper 13 shown in FIGS.
4 has a configuration in which a guide rail 12 is provided along the transport direction.

The guide rail 12 is, as shown in FIG.
It is made of a steel material having an inverted V-shaped cross section and has a length slightly shorter than the opening width of the hopper 13 in the front-rear direction. The guide rail 12 is fixed to the hopper 13 by horizontal rails 21 fixed to the front and rear pair of the hopper 13.

That is, an inlet 14 is formed at an upper portion of a pipe 11 at a desired portion of the pipeline, and a hopper 13 is continuously provided so as to surround the inlet. The guide rail 12 is connected to the pipe 11 at an upper portion of an inlet 14 into which the hopper 13 and the pipe 11 communicate with each other and into which an object to be transferred is inserted.
Are arranged to extend in the transport direction of the endless chain 5 along the center line of the endless chain 5. Here, the position of the guide rail 12 is determined within the pipe 1 ′ connected to the hopper 13 by the pipe 11.
Is preferably set at a position corresponding to the peripheral wall.

The rear end 12c of the guide rail 12
3 is gradually curved in a direction away from the inlet 14 (upward in the illustrated example) as clearly shown in FIG. 3, and when the chain 5 or the blade 7 enters the inlet of the hopper 13, The guide rail 12 is formed so as not to be restricted by hitting the rear end portion 12c. Here, whether the chain 5 or the blade 7 comes closer to the inlet 14 depends on the direction in which the pipeline is bent before and after the hopper.

This curved portion may be formed at both front and rear ends of the guide rail 12, and in this case, the same effect can be obtained even if the transport direction of the endless chain 5 is changed between forward and reverse. Therefore, the chain 5 or the blade 7 can reliably engage with or abut on the guide rail 12 and pass through the opening of the hopper 13 by the rear end portion 12c.

In the present embodiment, since the guide rail 12 has an inverted V-shaped cross section, the load fed from the hopper 13 is guided by the inclined surface 12a and does not accumulate thereon. . Accordingly, the guide rail 12 has a surface 12a whose outer surface gradually descends laterally from the center line.
, And may be, for example, an inverted U-shaped cross section or a semicircular arc shape.

In this embodiment, since the groove 12b is formed on the inner surface of the guide rail 12, the raised chain 5 can be suppressed and can be slid in the transport direction by engaging with the groove 12b. When the blade 7 protrudes, the inner surface of the guide rail 12 may have a curved shape along the outer peripheral surface of the blade 7. (Or bucket) and any shape as long as it is slidable in the transport direction.

Next, the hopper 33 shown in FIGS.
Has a configuration in which a charging port 34 is provided at a position deviated to one side from the center of the pipe, and a wall forming a hopper 33 is erected so as to rise upward from the charging port 34. Therefore, the wall surface 31a of the large-diameter pipe 31 covering the lower side of the hopper 33 covers a vertical position along the center line of the pipe 31.

Therefore, when the link chain 5 is transferred below the hopper 33, the blade or the link chain is moved by the wall surface 31 of the large-diameter pipe 31 covering the lower side of the hopper 33.
Since it abuts with a, it can be pushed and moved without slipping on the transported object without being lifted further. A blade or a chain is disposed on the input port 34 side of the hopper 33 depending on a bending direction of the pipe connected to the hopper 33. In the case of a link chain, the blade or the chain extends substantially linearly. The wall surface of the pipe 31 needs to be covered beyond the center, but when the protrusion of the blade is suppressed, the width may be regulated by the width of the inlet.

Next, the hopper 43 shown in FIG.
The opening width of 4 is set to a length shorter than the diameter of the blade so that the blade connected to the link chain and pushing the object to be conveyed does not protrude more than a predetermined amount. In the illustrated example, the inlet 44 is set to, for example, about ／ or less of the diameter so as to prevent the blade from projecting upward more than a predetermined amount, thereby suppressing the floating of the blade. Also in this case, it is possible to efficiently carry the transported object as described above.

[0018]

According to the present invention, the guide rail is provided above the input port of the hopper, so that the lifting of the conveying means such as a chain or a blade can be suppressed. In addition, by providing the position of the inlet port offset to one side and covering the center of the pipe with the wall surface of the pipe, it is possible to suppress the lifting of the conveying means such as a chain or a blade. Further, the extruded body can be prevented from floating by reducing the width of the inlet. Thus, the transporting unit can reliably push the transported object in the transport direction without slipping on the transported object.
