Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a cargo sealing device for a cargo handling machine.
In particular, in a material handling machine that transports bulk goods by transferring the cargo handling path from a cargo transfer path by a belt conveyor to a cargo transfer path by a boom conveyor formed below, the bulk goods are transferred from the above transfer path to the transfer path below. The present invention relates to a cargo sealing device for a cargo handling machine that can guide loose materials without leaking them to the outside when dropping and transferring the cargo.

[Prior Art] Generally, when loading bulk coal, etc., there is a known cargo handling machine that uses a belt conveyor to form two transfer routes, connects these transfer routes to each other, and transfers the bulk material from the insertion side to the discharge side. It is being

A stacker is known as this type of cargo handling machine, and this stacker has a structure as shown in FIGS. 4 and 5.

As shown in the figure, a belt conveyor a forming a transfer path on the carry-in side is provided with a tripper b, and the tripper b is configured to raise the belt conveyor a upward and drop the bulk items.

A stacker c is provided on the delivery side of the tripper b, and the stacker c has a boom conveyor d for transferring the objects that have fallen from the tripper b to the ground side. The carry-in side of the boom conveyor d is located below the tripper b, and the carry-out end extends to the carry-out side so as to be able to rotate and freely move around the stacker body.

That is, the transfer route by the belt conveyor a and the transfer route by the boom conveyor d superimposed below it are connected.

Further, as shown in Fig. 5, the tripper b is provided with a tripper chute e that hangs downward from the tripper b, and this tripper chute e opens downward to guide the bulk material falling from the tripper b downward. It's becoming like that. A skirt f is provided on the boom conveyor d so as to face the tripper shot e. This skirt f
is designed to guide the bulk material falling from the trip shot e onto the boom conveyor d.

[Problems to be solved by the invention] By the way, in a cargo handling machine that allows loose objects to fall and transfer from one transfer path to another, as the transfer speed of the loose objects is increased, , the condition of loose items falling becomes worse. especially,
Conventionally, tritupassute e and skirt f
A gap was formed between them. If the transport speed of the bulk material is increased in such a state, there is a problem in that a large amount of dust and coal dust is generated outside from the gap. In addition, there was a problem in that loose objects falling through the tripashiute e collided with the skirt f and flew out.

Therefore, the present invention was devised to effectively solve these problems, and effectively transfers the loose materials falling from the tritupus chute to the transfer path formed by the boom conveyor, thereby generating loose material dust, coal dust, etc. It is an object of the present invention to provide a cargo sealing device for a cargo handling machine that can prevent this from occurring.

[Means and effects for solving the problem] Between the tripper chute hanging down from the output end of the tripper of the belt conveyor and the skirt part provided on the boom conveyor installed below the chute so as to be able to rotate and rise and fall freely. A device for sealing a gap includes a support member formed in an arch shape along the longitudinal direction of the conveyor and supporting the skirt portion from both sides by sandwiching the skirt portion, and a support member rotatably supported by the chute and supported by the chute. A seal cover member that extends over the skirt portion to seal these gaps, and a seal cover member that extends from the seal cover member in the forward and backward directions of conveyance so as to cover the upper part between the support members, and is sandwiched between the support members. The guide plate is constructed of a tripartite chute and a guide plate that rotates integrally with the conveyor and is overlapped and slidably engaged with the upper edge of the support member to allow the ups and downs of the conveyor. This is a seal between the skirt and the skirt.

[Example] An example of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, a tripper 2 is provided on a belt conveyor 1 that forms a transport path for cargo such as bulk materials. This tripper 2 is bent over the belt conveyor 1 and raised upwards so that the loose items being conveyed can fall thereon.

This tripper 2 is provided with a tripper chute 3.

This tripper chute 3 hangs down from the delivery end of the delivery end of the delivery end of the delivery end of the delivery end of the delivery end of the delivery end of the delivery end of the delivery end of the delivery end of the delivery end of the delivery end of the picker 2. In the illustrated example, a tripartite chute 3 is formed which accommodates the damper 4 and has an opening cross-sectional area facing downward and whose diameter is gradually reduced.

A stacker 5 is provided on the discharge side of the tripper 2, and the stacker 5 has a boom conveyor 6.

This boom conveyor 6 is configured to pick up the loose material that has fallen from the tripper chute 3 and guide it to the discharge side. That is, the transfer path by the boom conveyor 6 is connected to the transfer path by the belt conveyor 1.

Further, the boom conveyor 6 has a boom 7 supported by a stacker body, and is configured such that its discharge end can be raised and lowered and rotated around the tripper chute 3.

A skirt 8 is provided on the carry-in end side of the boom conveyor 6 for guiding loose materials from the tripper chute 3.

As shown in FIGS. 1 and 3, this skirt 8 includes a skirt portion 9 facing the tripper chute 3 and having an opening area that is sequentially enlarged, and a support member 1 that supports this skirt portion 9 on the boom conveyor 6.
It is mainly composed of 0.

The support member 10 includes an arch beam 11 and a longitudinal beam 1.
2 and a horizontal beam 13. The arch beam 11 is supported at both ends by the boom 7 and is bent upward in an arch shape. Further, the vertical beams 12 support the arch beam 11 by dividing it into equal intervals, and are arranged so that their upper ends 12a are exposed upward from the arch beam 11. The horizontal beams 13 are constructed so as to span the arch beams 11 over each other, as shown in FIG.

Further, a seal cover member 14 is provided for sealing this skirt 8 and the tripper chute 3 together.

This seal cover member 14 is configured to span the tripper chute 3 and the skirt portion 9 to seal the space between them. That is, the third
As shown in the figure, an annular gap 15 is formed between the tripashute 3 and the skirt portion 9.
This gap 15 will be closed by the seal cover member 14.

Specifically, the seal cover member 14 includes a support portion 16 that is expanded in the radial direction from the tripper shot 3;
It consists of a cover member 17 extending from this support part 16 to the skirt part 9. The support portion 16 is rotatably supported by the trip shot 3. Further, the support portion 16 and the cover member 17 are made of rubber material 18.
It is designed to be sealed by

Furthermore, guide plates 19 and 20 are provided on the cover member 17 along the arch beam 11. As shown in FIGS. 1 and 2, the guide plates 19 and 20 are hingedly attached to the cover member 17, overlapped on the upper edge of the arch beam 11, and extended to cover the upper part between the support members 10. ing. Also, guide plate 1

is adapted to be overlaid and slidably engaged on the upper edge of the. That is, the guide plates 19 and 20 close the openings on the upper insertion side and the unloading side of the skirt portion 9.

Next, the operation of the present invention will be described.

First, when the boom conveyor 6 moves up and down, as shown in FIG.
Rotate relative to 4.

In this case, each guide plate 1 is
9 and 20 slide along the arch beam 11 toward its delivery side. As shown in FIG. 1, these guide plates 19 and 20 close an opening formed on the loading/unloading side of the arch beam 11 with the cover member 17 in between. Further, as shown in FIG. 3, the gap 15 between the skirt portion 9 and the tripper shot 3 is closed by the support portion 16, the cover member 17, and the rubber material 18. Therefore, a passage is formed from the tripashute 3 to the skirt portion 9 that connects these continuously.

In addition, in the up-and-down movement in which the carry-in end of the boom conveyor 6 rises, the carry-in side guide plate 19 collides with the carry-in end of the boom conveyor 6 that is rotating. Since the carry-in guide plate 19 is connected to the cover member 17 by a hinge, it is bent in the event of a collision. In other words, the loading side guide plate 19
This will prevent the boom conveyor 6 from colliding with the carry-in end and being damaged.

Also, the boom conveyor 6 is
When the skirt 8 rotates around , the skirt 8 is rotated following the pivoting movement. That is, when the boom conveyor 6 rotates, the vertical beam 1 extends upward from the arch beam 11.
The upper end 12a of 2 is the loading/unloading side guide plate 1.
9 and 20. By hooking the loading/unloading guide plates 19 and 20 onto the upper end 12a of the vertical beam 12, the support portion 16 of the seal cover member 14 rotates around the tripper chute 3. In other words, Tritu Pashute 3 and Skirt 8
The turning operation of the boom conveyor 6 is allowed while a path is formed that connects the boom conveyor 6 continuously.

In this way, the present invention provides the seal cover member 14 between the trip shot 3 and the skirt 8 attached to the boom conveyor 6, thereby reducing the gap 15 between the trip shot 3 and the skirt 8.
is sealed. Therefore, even if the transfer capacity of bulk materials is increased, coal dust will not leak to the outside. Therefore, the environment around the cargo handling device can be protected.

In addition, it is possible to prevent loose objects from flying away.

Furthermore, since the guide plates 19 and 20 that cover the upper part of the support member 10 are supported by the fixed tripper shoot 3, the guide plates 19 and 20
The length of the support member 10 in the loading/unloading direction can be set short, and the device can be simplified and miniaturized.
Since the guide plates 19 and 20 are overlapped and slid on the upper edge of the support member 10, the sliding motion is approximately linear contact, and smooth sliding motion can be achieved.

In addition, in this invention, although the stacker was demonstrated, it is not limited to this. It can also be applied to a ship loader that performs cargo handling on a ship by shifting the transfer route from the carry-in side transfer route to the carry-out side transfer route.

[Effects of the invention] In summary, the present invention provides the following excellent effects.

(1) A seal cover member is provided between the tripashiute and the skirt provided on the boom conveyor that rotates and moves up and down.
