The upper part of the blending bin hopper 100 is closed by the cover 22 and only the chute 13 is in communication with the hopper 100. When the hopper 100 is moved along the top of the blending hopper 100 by the movement of the tripper car 10, the covers 22 connected to the link part are also moved to continuously close the hopper 100. It becomes possible.

In addition, a storage housing 24 for stacking and storing the cover 22 to be moved is further installed at the hopper 100 end of the blending bin. As the chute 13 moves along the hopper 100, the cover 22 stacked on the one side storage housing 24 is sequentially taken out, and the cover 22 enters and stacks on the other storage housing 24.

The storage housing 24 is a rectangular box structure, which roughly corresponds to the shape and size of the cover 22. An opening 26 is formed at the bottom of the storage housing 24 to allow the cover 22 to enter and exit. The cover 22 is stacked and stored in the storage housing 24. Accordingly, the storage housing 24 may be stacked in the storage housing 24 with all the covers 22 connected to the chute 13 based on when the chute 13 is completely moved to the end of the hopper 100 of the blending bin.

To this end, as shown in FIGS. 3 and 4, the link part is installed on the side of the cover 22 and moves in the guide member 40 and the guide member 40 having a long hole 42 formed in the longitudinal direction on the front surface thereof. The roller 44 is possibly installed, and the link member 46 is connected to the roller 44 installed at the guide member 40 of the neighboring cover 22.

The link portions are provided opposite to both side surfaces of the cover 22. The long hole 42 formed in the guide member 40 is smaller than the diameter of the roller 44 so that the roller 44 does not escape to the outside. The guide member 40 is provided with two rollers 44, each roller 44 is a roller 44 installed in the cover 22 adjacent to each end and the link member 46 through each other. Connected. In addition, the cover 22 has a structure in which a contact surface between the cover 22 is inclined downward toward the storage housing 24 to form an inclined surface 50. The inclination angle of the inclined surface 50 is not particularly limited.

The contact surface of the adjacent cover 22 has a structure where the inclined surfaces 50 which face each other contact. Accordingly, when the cover 22 and the cover 22 are in close contact with each other by the inclined surface 50, the one side cover 22 proceeds under the other cover 22.

When the cover 22 enters into the storage housing 24, the cover 22 enters under the front cover 22 along the inclined surface 50 of the front cover 22 and the link member 46 guides. It is moved along the long hole 42 of the member 40 to be stackable with each other in the storage housing 24. In addition, the contact surfaces between the cover 22 and the cover 22 are inclined to contact each other so that the upper end of the hopper 100 is not directly exposed through the cover 22 and the cover 22.

Hereinafter, the operation of the apparatus 20 will be described with reference to FIGS. 5 and 6.

When the hopper 100 is selected in the cab when the raw coal of the tripper car 10 is collected, the tripper car 10 moves on the hopper 100 for each type of coal. When the tripper car is moved, the chute 13 installed in the tripper car is moved along the top of the hopper 100.

The cover 22 is connected to both side ends of the chute 13 so that the cover 22 also moves in the longitudinal direction on the hopper 100 as the chute 13 moves.

Here, the travel roll 30 is installed at the upper end of the hopper 100 in the longitudinal direction to support the cover 22. Accordingly, the cover 22 can move the hopper 100 more smoothly by the rolling of the running roll 30.

As the chute 13 moves, the covers 22 connected to the front end in the traveling direction of the chute 13 enter the inside of the storage housing 24 installed at the end of the hopper 100 in the corresponding direction. On the contrary, the covers 22 connected to the opposite side to the traveling direction of the chute 13 are drawn out from the storage housing 24 installed in the corresponding direction.

Looking at the process in which the cover 22 enters and is stacked in the storage housing 24 as the cover 22 progresses.

When the cover 22 enters the storage housing 24, the cover 22 is no longer entered by the stop member 28 installed in the storage housing 24. Accordingly, the cover (hereinafter referred to as sun cover 22-1 for convenience of explanation) contained in the storage housing 24 is continuously connected to the following cover (hereinafter referred to as rear cover 22-2 for convenience of explanation). ) Is entered under the sunker by the inclined surface 50 of the tip. That is, the rear cover 22-2 follows the front inclined surface 50 of the front cover 22-1 while the front inclined surface 50 of the front cover 22-1 and the rear cover 22-2 are in close contact with each other. The cover 22-2 is moved below. Accordingly, the rear cover 22-2 enters directly under the sun cover 22-1 which enters the storage housing 24. Therefore, the sun cover 22-1 first entered into the storage housing 24 is lifted up, and then the rear cover 22-2 enters and is stacked below.

Here, the link member 46 connecting the sun cover 22-1 and the rear cover 22-2 is rotated while the hook cover 22-2 enters the sun cover 22-1. Along the long hole 42 of the guide member 40 is to move to the tip of the long hole 42. In this embodiment, the rotation radius of the link member 46 and the moving position of the rear cover 22-2 are substantially similar. As shown in FIG. 6, when the rear cover 22-2 moves under the sun cover 22-1, the link member 46 rotates to support the rear cover 22-2. After the rear cover 22-2 completely enters under the sun cover 22-1 and proceeds into the storage housing 24 along the traveling roll 30, the roller 44 installed on the link member 46 is also provided. By moving along the long hole 42, the rear cover 22 can continue to move.

When the rear cover 22-2 completely enters under the sun cover 22-1, the entering rear cover 22-2 is caught by the stop member 28, and the process stops, and then the cover 22 is connected thereto. After the above process again enters and stacked below. As the chute 13 moves, the covers 22 are sequentially stacked in the storage housing 24, and the upper portion of the hopper 100 in the traveling direction of the chute 13 continues to be closed by the cover 22. Will be maintained.

On the other hand, as the chute 13 moves, the cover 22 is drawn out from the storage housing 24 on the opposite side of the chute 13 in the moving direction. The lowermost cover 22 of the covers 22 stacked in the storage housing 24 is pulled out of the storage housing 24 as the chute 13 moves. When the lowermost cover 22 exits through the opening 26 of the storage housing 24, the link member 46 moves along the long hole 42. When the cover 22 is completely pulled out, the link member 46 is completely moved to the end of the long hole 42, so that the next cover 22 can be pulled out. The cover 22 stacked thereon can be sequentially taken out. Therefore, even when the chute 13 moves, the upper portion of the hopper 100 opposite to the traveling direction of the chute 13 continues to be closed by the cover 22.
