Description

  The present invention relates to a flight conveyor in which a number of flights are attached to an endless chain or other winding means, and more particularly to a flight conveyor used to drop collected garbage into a hopper.

  As water resources for power generation, agriculture, and industrial use, running water that flows down in a waterway branched from a river is used. The running water contains not only vegetation but also household waste such as empty cans and vinyl. In order to prevent the vegetation, domestic waste and other debris from flowing down to the power plant, for example, as shown in FIG. 4, a water intake screen device S for capturing the debris at a water intake at the boundary between the water channel and the river. And a hopper device H for disposing of the captured dust is disposed.

  The hopper device H is provided with a conveyor 1 having an inclined posture, a hopper body 2 disposed above a transport vehicle such as a truck, and the like. The conveyor 1 is in an inclined posture with the upstream end side disposed near the intake screen device S and the downstream end side disposed higher above the hopper body 2.

  As the conveyor 1, a flight conveyor capable of suitably transporting garbage is used. In this flight conveyor, a large number of flights are attached to a two-strand chain that runs over a sprocket at regular intervals, and a bottom plate (trough) that slides in contact with the back surface of a traveling flight is arranged in parallel. ing. The dust captured by the screen device S is transferred onto the trough on the upstream side of such a flight conveyor, the flight proceeds by driving the sprocket, and the dust on the trough is transferred downstream, It is dropped into the hopper body 2 from the downstream end.

  And the cleaner apparatus for flight conveyors for removing the dust adhering to a flight is disclosed by patent document 1. FIG. This cleaner device has a brush-like or rubber-plate-like wiper attached to one end of a pair of swingable wiper arms, and a return member attached to the other end. It is said that. The wiper scrapes the dust adhering to the flight into the hopper body 2.

  The return member is composed of a counterweight and the like, and a plurality of moment adjustment bolt holes are provided in the wiper arm so that the mounting position of the counterweight can be changed. By adjusting the moment, the size of the flight scraping surface is increased. It can be adapted to the traveling speed of the flight and the number of installed flights.

JP 2000-85938 A

  The flight conveyor is transported from the downstream end to the upstream end so that the flight pushes up the dust on the trough and dropped into the hopper body 2. May adhere to the back surface of the flight, and may not be dropped from the downstream end, but may fall from the returning flight to the outside of the hopper body 2 and scatter. The work of collecting the scattered dust is not only troublesome, but it can also pose a danger to workers traveling around the flight conveyor.

  Further, in the case of a flight conveyor in which a cover is provided on the lower side of the returning flight, dust adhering to the returning flight may be caught between the cover and the flight. Since the flight conveyor is normally operated unattended, even if dust is caught between the cover and the flight, the flight continues to return without stopping. As a result, the flight conveyor is electrically overloaded and may fail.

  Therefore, the dust adhering to the returning flight must be removed. However, if this is performed manually, not only labor costs will be incurred, but there is also a risk of personal injury due to malfunction of the flight conveyor.

  In addition, the flight conveyor cleaner disclosed in Patent Document 1 must not only assemble a pair of wiper arms and wipers, but also must accurately attach the counterweight to the adjustment bolt hole. Not only is it cumbersome, it also contributes to an increase in cost.

  Then, this invention makes it a subject to provide the flight conveyor which enabled it to remove reliably the dust adhering to a flight, without raising a cost.

Flight conveyor according to the present invention is a flight conveyor having an upstream end and a downstream end, a number of flight endlessly wound conducting means is attached at intervals in the circumferential direction, the upstream end at least sliding contact flight conveyor der bottom plate is arranged is, the of the flight on the rear surface of the flight is folded back on the back and the downstream end of the flight which moves forward toward the downstream end of section A sheet having a width substantially the same as the width in the direction intersecting the circumferential direction is provided, a base end side of the sheet is attached to a downstream end portion of the bottom plate, and a leading end side of the sheet is suspended. .

According to this flight conveyor, the dust is transported on the bottom plate from the upstream side to the downstream side by flight and falls at the downstream end. However, the dust adhering to the back side of the flight does not fall at the downstream end and moves on the sheet from the base end side to the front end side. Then, the front end side of the sheet gradually rises from the state where the flight is suspended due to the backward movement of the flight, and when the flight departs from the front end edge of the seat, the front end edge of the sheet adheres to the back side of the flight. The object is forcibly scraped off, and the leading end side of the sheet hangs down again.

  In the flight conveyor according to the present invention, the sheet is preferably formed of flexible rubber.

  According to this flight conveyor, since the sheet is formed of flexible rubber, the sheet can be provided with functionality and durability. That is, the drooping tip side rises smoothly due to the backward flight. Then, when the flight passes through the lower edge of the raised sheet, the leading end side of the sheet hangs while swinging away the dust attached thereto while swinging.

Further, in the flight conveyor according to the present invention, the sheet is fixed to the bottom plate only Mototan'en, which is preferably carried by the surface Gaga Idoba of the intermediate portion between the proximal side and the distal side .

According to this flight conveyor, only the base end edge of the sheet is fixed to the bottom plate by supporting the surface of the intermediate portion between the base end side and the front end side of the sheet below the flight. However, the base end side of the sheet can follow the bottom plate of the downstream end portion. After the front end side of the sheet is increased by flight being backward, leading edge of the sheet is removed from the flight, when the tip end of the sheet droops, the base end side of the sheet in contact with the guide bar and the front end side The leading end side of the sheet swings with a length from the intermediate portion between the sheet and the leading edge of the sheet. That is, if the guide bar is not provided, the leading end side of the sheet that has been lifted and drooped swings in a length from the position in contact with the subsequent backward flight to the leading edge of the sheet. However, since the guide bar is provided, the leading end side of the sheet swings without a certain length.

  According to the present invention, the flight conveyor is provided with a sheet having substantially the same width as the flight, the base end side of this sheet is attached to the downstream end of the bottom plate that is in sliding contact with the back surface of the flight, and the leading end side of the sheet is suspended. As a result, the dust attached to the back surface of the flight is surely scraped off by the sheet. Therefore, the present flight conveyor can reliably drop the garbage in, for example, the hopper body disposed on the lower side of the downstream end of the flight conveyor.

  An embodiment of a flight conveyor according to the present invention will be described with reference to FIGS. However, the same parts as in the prior art will be described with the same reference numerals.

  As shown in FIG. 1, the flight conveyor according to the present embodiment has a plurality of flights 13, 13,... Spaced apart from each other by two endless chains 12, 12 suspended in an inclined posture on the sprocket 11. Are mounted in parallel, and a bottom plate 14 slidably contacting the back surface of each flight 13, 13,... Is arranged side by side, and a rectangular sheet 20 having the same width as that of the flights 13, 13,. It is characterized by that. The sprocket 11 is supported by the frame 15 and the bottom plate 14 is fixed.

  In addition, the bottom plate 14 may be juxtaposed so as to be in sliding contact with the back surfaces of the forwardly moving flights 13, 13,... And the backwardly moving flights 13, 13,. .. May be arranged in parallel so as to be in sliding contact only with the back surfaces of the flights 13, 13,... And the back surfaces of the flights 13, 13,. And the upstream side edge part (when arranged in parallel) and the bottom plate 14 of the downstream side edge part are formed in a circular arc (semicircle) shape. Further, the thickness of the bottom plate 14 is thicker on the side where the flights 13, 13,... Move forward, and thinner on the side where the flights 13, 13,. A groove into which the sheet 20 is fitted is formed in the width direction at substantially the center of the side arc shape.

  The seat 20 is formed of rubber that is flexible enough to be lifted and lifted by the backwardly moving flights 13, 13,..., And the proximal end 21 is attached to the downstream end of the bottom plate 14, Side 22 is depending. Therefore, the base end edge 21 a of the sheet 20 is fitted into the groove of the bottom plate 14 as described above, and is fixed by the screw 16. A countersunk screw is used for the screw 16 and a countersink is formed in the bottom plate 14 so that the head of the screw 16 does not protrude from the surface of the bottom plate 14.

The sheet 20 is supported by a guide bar 17 in which a surface of an intermediate portion between the proximal end side 21 and the distal end side 22 is fixed to the frame 15. The guide bar 17 is positioned below the flights 13, 13,... That move backward so that the base end side 21 of the seat 20 follows the arcuate bottom plate 14 at the downstream end.

  Further, the maximum length of the front end side 22 in the state where the seat 20 is not lifted by the flight 13 and is suspended so that the front end side 22 is not bridged between the adjacent flight 13 and the flight 13 is a flight. 13 is shorter than the pitch between the flight 13 and the flight 13. Since the seat 20 is formed of flexible rubber, the maximum length of the front end side 22 of the seat 20 is longer than the pitch between the flight 13 and the flight 13, and even if it is bridged between the flight 13 and the flight 13, The middle of the stretched front end side 22 hangs down and the front end edge 22a is disengaged from the preceding flight 13, but the front end side 22 can be operated smoothly regardless of the degree of flexibility of the seat 20. The maximum length is preferably shorter than the pitch between the flights 13 and 13.

  This flight conveyor is configured as described above, and the usage method will be described next. The garbage G captured by the water intake screen device S (see FIG. 4) is transferred to the upstream end of the flight conveyor. When the sprocket 11 is driven, the chains 12 and 12 travel, and the flights 13, 13,. Therefore, as shown in FIG. 2, the dust object G is transferred to the downstream side on the bottom plate 14 by flights 13, 13,.

  Then, the dust object G falls by its own weight at the downstream end and is put into the hopper body 2. However, the dust object G sandwiched between the flight 13 and the bottom plate 14 does not fall by its own weight, and moves on the sheet 20 while adhering to the back surface of the flight 13 when the flight 13 moves backward. Then, as shown in FIG. 3, the returning flight 13 moves the dust object G on the sheet 20, gradually lifts the leading end side 22 of the hanging sheet 20, and raises the leading edge 22 a.

When the returning flight 13 is disengaged from the leading edge 22a of the raised sheet 20, the dust G attached to the flight 13 is scraped to the leading edge 22a of the sheet 20, and at the same time the leading edge 22 of the sheet 20 is Drooping vigorously. The maximum length of the front end side 22 of the sheet 20 is made shorter than the pitch between the flights 13 and 13, and the surface of the intermediate portion between the base end side 21 and the front end side 22 of the sheet 20 is formed on the guide bar 17. Because of the contact, the front end side 22 of the sheet 20 swings around the guide bar 17, and the dust G scraped off by the front end edge 22 a of the sheet 20 is shaken off toward the hopper body 2.

  In this way, the debris G captured by the water intake screen device S is transported from the upstream side to the downstream side by the traveling flights 13, 13,..., Put into the hopper body 2 by its own weight, and further drooping Because the seat 20 is shaken off by the front end side 22, it is not returned to the upstream side again by the returning flights 13, 13,.

  In addition, this invention can be variously changed within the range of the technical matter described in the claim, without being limited to the said embodiment. For example, particularly when the pitch of the flights 13, 13,... Is short, the seat 20 may follow the arcuate bottom plate 14 by the flights 13, 13,. it can. Further, the sheet 20 is not limited to rubber and may be formed of a soft resin. Furthermore, the number of the chains 12 and 12 is not limited to two, and may be one, or a rope or the like may be used instead of the chains 12 and 12.

  The flight conveyor of the present invention is used for removing the dust G in the running water for agriculture and industrial use, in addition to removing the dust G in the running water flowing down the power generation waterway. Therefore, the present invention can be carried out not only when the flights 13, 13,.
