Description

  The present invention relates to a bulk conveyor sorter that sorts and drops coal, ore, silica sand and other bulk materials transported on a conveyor according to a supply position.

  Conventionally, for example, when bulk materials are supplied to and loaded on a ship by a bulk conveyor, the bulk materials are installed on the quay, the tip side of the belt conveyor is extended to a supply position on the ship, and the bulk materials are transferred by the conveyor. . Further, when transferring to a different bulk storage location 5 to 6 m away on the ship, the ship is moved to change the position. However, in order to change the position of the ship, it is necessary to loosen the mooring ropes and move the ship while positioning the ship, which requires more than one hour. For this reason, it takes time and effort to load bulk materials, and the operation cost is high.

  An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a bulk conveyor sorter having a simple structure capable of sorting bulk materials to a distant place and supplying the bulk materials at a low cost.

  In order to achieve the above object, the present invention is characterized in that it is provided at one end of the bulk conveyor and separates the bulk material which is conveyed by the bulk conveyor and falls from one end along the bulk conveyor. A tip frame member attached to one end of the bulk conveyor and extending in an extending direction thereof, and a plate-shaped bulk receiving member disposed below one end of the bulk conveyor. A bulk receiving member fixed at one end to the middle of the bulk receiving member in the direction along the bulk conveyor and at both ends in the width direction, and attached at the other end to the widthwise both sides at the tip side of the bulk conveyor. A pair of suspension chains for rotatably suspending the member, an electric winch attached to the tip of the end frame member for pulling or loosening the chain, and the other end from the attachment position of the suspension chain of the bulk conveyor. Separation An electric winch that is attached at a position where the chain is pulled or loosened, and a distribution chain that is connected to the front electric winch and the rear electric winch and that hangs down and is fixed to one end of the bulk receiving member at an intermediate position. By controlling the driving of the electric winch and the rear electric winch in synchronization, the length from the fixed position of the sorting chain to the bulk receiving member to the front electric winch and the rear electric winch is adjusted, and the surface of the bulk receiving member is adjusted. And a controller that makes the inversion possible.

  In the invention configured as described above, by controlling the driving of the front electric winch and the rear electric winch in synchronization by the controller, first, the length from the bulk receiving member of the sorting chain to the front electric winch side is shortened. By adjusting the length from the bulk receiving member to the rear electric winch to be longer, the bulk receiving member can be inclined in such a manner that the end frame member side faces downward. Thereby, the bulk material dropped from the bulk conveyor can be dropped to a supply position farther than the conveyor. On the other hand, the length of the distribution chain from the bulk receiving member to the front electric winch side is increased by the controller, and the length from the bulk receiving member to the rear electric winch is adjusted to be shorter. Can be rotated about the suspension chain so that the upper and lower surfaces are inverted, and the bulk receiving member can be tilted so that the rear electric winch side faces downward. Thereby, the bulk material dropped from the bulk material conveyor can be dropped to the supply position on the other end side with respect to the tip of the conveyor.

  As a result, in the present invention, the bulk material can be dropped and supplied to two separate feeding positions on the tip side along the bulk conveyor. For this reason, for example, by changing the inclination of the bulk receiving member with a controller for two bulk supply positions about 5 m apart on a ship, it is not necessary to move the boat to adjust the position, and the bulk can be quickly removed. It can be easily supplied.

  In the bulk conveyor sorting device of the present invention, bulk materials can be easily supplied to two supply positions, for example, about 5 m apart on a ship without moving the ship to adjust the position. It is possible to reduce the time and the transportation cost of the transportation operation of the object.
