Description

  The present invention relates to a reclaimer used for paying out roses from a pile of roses (ore, coal, etc.) stored in a yard.

  In the payout operation by the reclaimer, the loose objects in the pile are picked up by the bucket wheel, the loose objects stored in the bucket of the bucket wheel are dropped on the conveyor, and the loose objects dropped on the conveyor are transported to a predetermined position. (For example, refer to Patent Document 1).

  Here, by moving the carriage frame that rotatably supports the bucket wheel in the width direction of the pile, the loose article in the pile direction is paid out, and this payout operation is sequentially performed in the longitudinal direction of the pile. It is possible to pay out the roses of the whole mountain. The conveyor that receives the fallen objects that have dropped from the bucket wheel extends in the width direction of the pile, and at one end of the conveyor (on the head pulley side), the loose objects are delivered to other conveyors.

  The specific structure of the conveyor which receives a rose thing from this bucket is demonstrated using FIG. FIG. 5 shows the configuration of the other end side of the conveyor (the side opposite to the side for collecting loose objects) in a conventional reclaimer.

  The bucket wheel 100 is disposed perpendicular to the horizontal plane and can move in the width direction of the mountain as indicated by an arrow D21 in FIG. The mountain is housed in a yard surrounded by a retaining wall 110. When the bucket wheel 100 rotates in the direction indicated by the arrow D22 in FIG. 5, the plurality of buckets arranged on the outer periphery of the bucket wheel 100 scoops up loose objects.

  The roses picked up by the bucket wheel 100 (bucket) fall and are supplied to the conveyor belt 120 extending in the width direction of the pile (direction of arrow D21), and move along the conveyor belt 120 to the outside of the yard. Be transported. Here, the conveyor belt 120 moves in the direction indicated by the arrow D <b> 23 in FIG. 5 and passes through the inside of the bucket wheel 100.

  The return part of the conveyor belt 120 has three pulleys 121 to 123. Specifically, the conveyor belt 120 is in contact with a first pulley (tail pulley) 121 and a second pulley 122, and a tension weight 124 is attached between the first pulley 121 and the second pulley 122. Three pulleys 123 are arranged. When the weight of the tension weight 124 acts on the conveyor belt 120 via the third pulley 123, it is possible to apply tension to the conveyor belt 120 and prevent the conveyor belt 120 from slackening.

  In order to efficiently collect loose objects in the yard, the bucket wheel 100 moves to the vicinity of the retaining wall 110, and the pulleys 121 to 123 do not interfere with the bucket wheel 100 and the retaining wall 110. Against the outside of the yard.

  In the configuration shown in FIG. 5, loose objects attached to the conveyor belt 120 may fall from the conveyor belt 120 due to vibration or the like. Here, when a loose article falls from a portion of the conveyor belt 120 located above the yard, the loose article returns into the yard.

  However, in the configuration shown in FIG. 5, in order to avoid interference with the bucket wheel 100, the return portion of the conveyor belt 120 (the portion that contacts the pulleys 121 to 123) is disposed outside the yard with respect to the retaining wall 110. For this reason, when a rose falls from this portion, the rose does not return to the yard, and the roses accumulate outside the yard. Here, on the outside of the yard, a rail for moving the reclaimer in the longitudinal direction along the mountain is arranged, and the fallen roses accumulate on the rail. It is necessary to periodically remove things.

  The present invention prevents the rails from being buried with the fallen fallen object by setting the position where the fallen object falls from the return side of the belt conveyor 120 to the inner side (mountain mountain side) of the retaining wall 110, and the fallen rose. It is an object to make it possible to pick up an object with the bucket wheel 100.

The present invention relates to a reclaimer that is provided so as to be movable in the longitudinal direction of a pile in order to pay out loose articles from the pile that is housed in a yard surrounded by a retaining wall, and that extends in the width direction of the pile. If, when viewed from the traveling direction of the reclaimer, a pair of bucket wheels spacing of the upper is inclined respectively to be narrower than the interval of the lower, it is arranged on the inner side of the pair of buckets wheels, via a chute will receive the rose was dropped from the bucket wheel Te, and feeder conveyor extending from said chute to the traveling direction of the reclaimer, holding the bucket wheel and the feeder conveyor, a carriage frame that moves along the bridge frame , together with the bridge frame to move in the traveling direction of the reclaimer, said Fidako Receiving roses product from Beya transported along the longitudinal direction of the bridge frame, and has a relay conveyor Terupuri is located retaining walls inside above the yard, the.

  In the tail pulley, a take-up device for applying tension to the relay conveyor can be provided. Moreover, the chute | shoot which guides the rose which fell from the take-up apparatus in a yard can be provided in the lower surface of a take-up apparatus. Thereby, the rose which fell from the take-up device can be efficiently returned to the yard.

  According to the present invention, the feeder conveyor can be arranged by inclining the bucket wheel, and the relay conveyor can be arranged at a position away from the bucket wheel by the feeder conveyor. This prevents the relay conveyor and bucket wheel from interfering with each other, allowing the tail pulley of the relay conveyor to be positioned inside the yard retaining wall, preventing the rails from being buried by falling objects, and periodically This eliminates the need for a bulky object removal operation, and enables the fallen object dropped from the relay conveyor to be returned to the yard, so that the loose object can be efficiently discharged from the pile.

  A ground conveyor (belt conveyor) 14 extending along the rail 12 is disposed below the traveling frame 11, and loose articles are supplied to the ground conveyor 14 from a relay conveyor 50 as described later.

  The bridge frame 10 supports a carriage frame 20, and the carriage frame 20 is movable along the longitudinal direction of the bridge frame 10 (left and right direction in FIG. 1).

  The carriage frame 20 includes a carriage body 21 and arms 22R and 22L extending upward (vertical direction) from the carriage body 21. The arms 22R and 22L are spaced apart in the longitudinal direction of the bridge frame 10, and support portions 221R and 221L are provided at the tips of the arms 22R and 22L.

  Further, two arms 22R are provided, and are arranged at positions sandwiching the bridge frame 10 as shown in FIG. Two arms 22L are also provided, and are arranged at positions sandwiching the bridge frame 10.

  As shown in FIG. 2, a transverse wheel 23 is rotatably attached to each support portion 221R. The traversing wheel 23 is in contact with the upper surface of the bridge frame 10 and moves in the longitudinal direction of the bridge frame 10 on the upper surface of the bridge frame 10. The support portion 221L is also provided with a traversing wheel similar to the traversing wheel 23 described above. The traversing wheel contacts the upper surface of the bridge frame 10 and moves along the longitudinal direction of the bridge frame 10. .

  As a mechanism for moving the carriage frame 20 along the bridge frame 10, for example, a rack and pinion mechanism can be used. Specifically, a rack can be provided along the longitudinal direction of the bridge frame 10, and a motor in which a pinion that meshes with the rack is attached to the output shaft can be provided in the carriage frame 20.

  Thus, by driving the motor and rotating the pinion, the pinion moves along the rack, and the carriage frame 20 can move along the bridge frame 10. In the present embodiment, a mechanism for moving the carriage frame 20 is disposed at a position shown in a region E in FIG.

  The mechanism for moving the carriage frame 20 is not limited to the above-described mechanism, and it is sufficient that the carriage frame 20 can be moved along the bridge frame 10. For example, a wire is fixed to the carriage frame 20, and the carriage frame 20 can be moved by a wire winding operation.

  The carriage frame 20 is provided with two halos (scraping tools). Each halo crushes a pile of roses stored in the yard 200 and drops the roses downward. FIG. 2 shows a part of the halo 24.

  Two bucket wheels 30R, 30L are attached to the carriage frame 20 in a rotatable state, and a plurality of buckets 31R, 31L are arranged in the circumferential direction of the bucket wheels 30R, 30L. The bucket wheels 30R and 30L are inclined in a C shape with respect to the vertical plane. Specifically, the bucket wheels 30R and 30L are inclined in the direction in which the upper portions of the bucket wheels 30R and 30L approach each other. Yes. In other words, the interval at the upper part of the bucket wheels 30R, 30L is narrower than the interval at the lower part of the bucket wheels 30R, 30L.

  A motor (not shown) is connected to the rotation shaft of each bucket wheel 30R, 30L, and each bucket wheel 30R, 30L rotates upon receiving the rotational force of the motor. Specifically, as shown in FIG. 2, the bucket wheel 30R rotates in the direction indicated by the arrow D12. The rotation shafts and motors of the bucket wheels 30R and 30L are supported by the carriage frame 20, respectively.

  The bucket 31R scoops up the roses scraped by the halo by a rotating operation. That is, in accordance with the rotation of the bucket wheel 30R, loose objects enter the bucket 31R from the opening (uptake port) of the bucket 31R. The same applies to the bucket wheel 30L.

  As shown in FIG. 1, the inclination angle (acute angle) θ with respect to the vertical plane of each bucket wheel 30R, 30L is preferably 5 degrees or more and smaller than 20 degrees. The inclination angle θ is an angle between a radial surface (virtual surface) and a vertical surface of each bucket wheel 30R, 30L.

  The loose article taken into the bucket 31R falls due to the action of gravity when the bucket 31R reaches the upper side by the rotation operation of the bucket wheel 30R. The fallen rose reaches the feeder conveyors (belt conveyors) 40R and 40L via the chute 32 (see FIG. 3).

  The feeder conveyor 40 </ b> R is provided in order to convey the bulk material from the bucket 31 </ b> R to the relay conveyor (belt conveyor) 50. The feeder conveyor 40R is located in a plane orthogonal to the longitudinal direction of the bridge frame 10, and the belt of the feeder conveyor 40R moves in the direction indicated by the arrow D13 in FIG. In addition, the feeder conveyor 40R should just be able to convey the loose article which fell from the bucket 31R in the direction away from the rotating shaft of the bucket wheel 30R.

  When the loose objects on the feeder conveyor 40R move to one end (head pulley side end) of the feeder conveyor 40R as the belt moves, they fall from the feeder conveyor 40R and reach the relay conveyor 50 via the chute 53.

  As shown in FIG. 1, a feeder conveyor 40L is also provided for the bucket wheel 30L, and the feeder conveyor 40L has the same structure as the above-described feeder conveyor 40R. And the loose thing taken in into the bucket 31L of the bucket wheel 30L falls on the feeder conveyor 40L, and is supplied to the relay conveyor 50 by the feeder conveyor 40L.

  The relay conveyor 50 includes a tail pulley 51 and a head pulley 52, and is placed on the carriage body 21 and extends in the width direction of the pile, as shown in FIG. Further, the relay conveyor 50 is separated from the bucket wheels 30R and 30L by a predetermined distance (a distance corresponding to the length of the feeder conveyors 40R and 40L), and the moving direction of the bucket wheels 30R and 30L and the extension of the relay conveyor 50 Since the direction is parallel, the bucket wheel 30L and the relay conveyor 50 do not interfere with each other.

  The loose article supplied on the relay conveyor 50 moves in the direction indicated by the arrow D11 in FIG. 1 along with the movement of the belt, and falls from the head pulley 52 side. Below the head pulley 52, the ground conveyor 14 is disposed, and the loose objects that have fallen from the relay conveyor 50 reach the ground conveyor 14. The loose objects on the ground conveyor 14 are conveyed to a predetermined position.

  The tail pulley 51 of the relay conveyor 50 is provided with a take-up device 54. The take-up device 54 is used to adjust the tension of the belt of the relay conveyor 50, and a known configuration can be appropriately used.

  In the take-up device 54 shown in FIG. 3, a moving carriage 54a provided with a bearing for the rotating shaft of the tail pulley 51 is supported on the upper and lower surfaces of the frame 54b. Is fixed. The groove of the rack 54c is provided with a pinion (not shown) on the front surface of the frame 54b so as to be engaged with the groove of the rack 54c. By rotating the handle 54d, the tail pulley is interposed via the pinion and the rack 54c. 51 is configured to move.

  Further, as shown in FIG. 3, the tail pulley 51 is located at an upper portion in the vertical direction with respect to the retaining wall 201.

  A chute 55 is disposed at the bottom of the take-up device 54. The chute 55 is configured to receive loose objects dropped from the relay conveyor 50 in the yard 200, and the bucket wheel 30L comes to the end of the relay conveyor 50 on the tail pulley 51 side. Is provided to guide the bucket 31L to a scooping position. In this embodiment, the chute 55 is formed in a flat plate shape, but is not limited thereto. That is, it is only necessary that the falling object falling from the take-up device 54 can be returned into the yard 200, and the shape of the chute 55 can be appropriately set based on this point.

  In this embodiment, since the tail pulley 51 of the relay conveyor 50 is located inside the retaining wall 201 that defines the yard 200, even if a loose object falls from the relay conveyor 50, this loose object is removed from the yard 200. Can be brought back up. As shown in FIG. 3, the rose falling from the tail pulley 51 becomes a deposit 300 inside the retaining wall 201.

  In particular, the tail pulley 51 portion of the relay conveyor 50 reverses the direction of the belt, so that loose objects attached to the belt easily fall. For this reason, by returning the rose falling from the tail pulley 51 portion of the relay conveyor 50 to the yard 200, it can be scooped by the bucket wheel 30L and can be dispensed without leaving the rose on the yard 200.

  Further, in this embodiment, as shown in FIG. 1, the bucket wheels 30R and 30L are provided so as to be inclined in a letter C shape, so that the relay conveyor 50 and the bucket wheels 30R and 30L may be provided apart from each other by a predetermined distance. Therefore, the interference between the bucket wheel 30L and the relay conveyor 50 can be eliminated. As a result, the bucket 31R rotated to the position (lower position) for scooping the loose objects can be brought close to the retaining wall 201 as shown in FIG.

  Further, since the relay conveyor 50 and the bucket wheels 30R and 30L can be provided at a predetermined distance, the take-up device 54 disposed on the tail pulley 51 of the relay conveyor 50 interferes with the bucket wheel 30L. Can be prevented. That is, the take-up device 54 and the bucket wheel 30L do not interfere when viewed from the direction shown in FIG. In FIG. 4, the take-up device 54 is omitted, and the take-up device 54 and the bucket wheel 30 </ b> L overlap each other when viewed from the traveling direction of the reclaimer 1.

  Thereby, the loose thing returned to the vicinity of the retaining wall 201 can be scooped up by the bucket wheel 30L. That is, the loose article dropped from the tail pulley side of the relay conveyor 50 can be efficiently scraped by the bucket wheel 30L.

  In order to avoid interference between the take-up device 54 and the bucket wheel 30 </ b> L, it is conceivable that the take-up device 54 is disposed outside the yard 200 with respect to the retaining wall 201. However, in this case, the loose objects attached to the relay conveyor 50 may fall outside the yard 200, and the loose objects in the yard 200 cannot be dispensed without waste.
