Description

Raw material charging apparatus and method {Charging apparatus for raw material and method thereof}

The present invention relates to a raw material charging apparatus and method, and more particularly, to a raw material charging apparatus and method capable of removing falling objects, dust, etc. generated during the raw material charging.

In general, a tripper facility is used in a steel mill or a power plant when the raw material transferred from the yard is charged into a storage unit. The tripper facility is formed so that a part of the belt conveyor can be moved in a predetermined section, and the discharge position of the raw material conveyed by the belt conveyor can be adjusted. Such a tripper facility is mainly installed above a plurality of reservoirs for charging raw materials, and may distribute raw materials to a plurality of reservoirs or may be charged into different reservoirs for each raw material. As described above, since the tripper facility is installed on the upper part of the storage device, the raw material is dropped from the belt conveyor and charged into the storage device. Accordingly, the belt conveyor is provided with a charging chute that forms a falling path or a conveying path of the raw material while moving along with it.

On the other hand, the storage device is installed in the lower part of the tripper facility, the upper portion of the storage device, for example, around the storage entrance, a working space formed of a deck or the like is secured. In addition, a grid-shaped screen is installed at the loading port of the storage device to prevent the worker from falling and to uniformly charge the raw material into the storage device. However, when loading raw materials into the storage unit in the tripper facility, some of the raw materials collide with the inner surface or screen of the storage unit, spill out to the upper outside of the storage unit, and accumulate on the loading surface or the road surface of the work space, generating a large amount of dust, etc. There was a problem that the work space was polluted.

In order to solve this problem, a cover part that can cover the charging port was installed in the lower part of the charging chute to suppress the leakage of raw materials and the generation of dust. In addition, a removal unit in contact with the charging surface or the road surface of the work space is installed at the lower end of the cover, and the removal unit is brought into contact with the charging surface in the process of moving the belt conveyor or charging chute to reload the raw material accumulated on the charging surface into the reservoir. . However, as time passes, the removal part wears out due to friction with the charging surface, and a space is formed between the charging surface and the removal part, which makes it difficult to reload the raw material accumulated on the road into the reservoir. Accordingly, the removal unit needs to be replaced frequently, but the operation is interrupted during replacement of the removal unit, thereby reducing operation efficiency, and increasing cost and work burden.

It may include a raw material charging device 120 installed in the. Here, the raw material may include various raw materials such as iron ore, coke, coal, alloy iron, etc. used in a steel mill or a power plant.

First, the storage 212 may be installed in one or a plurality of the lower portion of the raw material loading equipment. When there are a plurality of reservoirs 212 , the reservoirs 212 form a column and may be installed continuously or intermittently. For example, the reservoir 212 includes a first reservoir 212a that can store iron ore, a second reservoir 201b that can store coke, and a third reservoir 212c that can store ferroalloy. can do. The storage 212 may be installed in a column by being disposed along one direction. A charging port 213 may be formed in the upper portion of the reservoir 212 to charge raw materials, and a grid-shaped screen 214 may be installed in the charging port 213 . The screen 214 may serve to uniformly disperse the raw material discharged from the raw material loading device in the reservoir 212 . In addition, structures such as decks and work tables are installed around the charging port 213 of the storage 212 , and may be used as a road surface or the ground of a work space where a worker can move, or may be used as an installation site of other equipment. Hereinafter, the surface of the structure formed around the charging port 213 of the upper portion of the reservoir 212 or the reservoir 212 is referred to as a charging surface (E).

At least a portion of the raw material loading facility moves along the direction in which the storage 212 is installed, and transports the raw material from the yard to load the raw material into each of the plurality of storage 212 .

The raw material transport device 110 extends along the direction in which the reservoir 212 is arranged, and the traveling rail 111 installed on one side of the reservoir 212 and the traveling rail 111 are movable along the upper part. It may include a belt conveyor 112 to be installed. In this case, the belt conveyor 112 may be formed to extend to the yard, or it may be formed to extend to a conveying device such as another belt conveyor (not shown) that transports the raw material discharged from the yard, but in this case, the traveling rail A region formed to be movable along (111) is called a belt conveyor (112).

The traveling rail 111 is spaced apart from the charging surface E, and may be installed along the direction in which the storage 212 is disposed.

The belt conveyor 112 has a support frame 112a disposed in parallel with the traveling rail 111 and a roller 112d that is disposed in a direction crossing the traveling rail 111 and is rotatably connected to the support frame 112a. ), the rollers 112d and the rollers 112d, and may include a pulley (not shown) rotatably connected to the support frame 112a and a belt 112b disposed to surround the pulley. In addition, the belt conveyor 112 includes a wheel 112c connected to the support frame 112a to move along the traveling rail 111, and a motor (not shown) capable of providing power to the wheel 112c. may include Both sides of the support frame 112a may be formed to have a height difference, and the belt 112b may be disposed to be inclined to the support frame 112a. For example, the support frame 112a may have a front side higher than the rear side in the feeding direction of the raw material, and the belt 112b may be disposed to be inclined upwardly toward the front side in the feeding direction of the raw material. Here, the conveying direction of the raw material has been described with reference to FIG. 1 , and in FIG. 1 , the forward direction in the raw material conveying direction may mean the left, and the rearward direction in the raw material conveying direction may mean the right side. The pulley may be formed on one side of the upper part of the support frame (112a) and one side of the lower part of the support frame (112a), and although not shown, it is formed on both sides and the lower part of the running rail (111) in the extending direction of the running rail (111), respectively. can be At this time, the belt 112b may be bent to have an S-shape at one side of the support frame 112a. In addition, the belt 112b is formed to surround the plurality of pulleys, and a closed loop may be formed along a path for transporting or transporting raw materials, for example, the traveling rail 111 . Through this configuration, the belt conveyor 112 may move along the traveling rail 111 to transport the raw material to the storage location. In addition, the belt conveyor 112 may be charged into the storage 212 by dropping the raw material after raising it. Here, an example of the belt conveyor 112 will be described, and the structure of the belt conveyor 112 may be variously changed.

Figure 2 is a perspective view showing a raw material loading device according to an embodiment of the present invention, Figure 3 is an exploded perspective view of the removal unit shown in Figure 2, Figure 4 is the raw material loading along the line A-A' shown in Figure 2 It is a cross-sectional view of the device.

2 to 4 , the raw material loading device 120 is a raw material transport device 110 , for example, to charge the raw material transported or transferred by the belt conveyor 112 to the storage 212 , the raw material is transported. It is possible to form a path to become or a path to fall. The raw material charging device 120 is formed to surround the outer side of the charging chute 122 and the charging chute 122 installed so that the raw material can pass through and moveable, and a cover connected to the lower portion of the charging chute 122 . It may include a removal unit 140 movably connected to the cover unit 124 in the vertical direction so as to protrude lower than the lower end of the unit 124 and the cover unit 124 . In addition, when the raw material is discharged from the belt conveyor 112 to the charging chute 122, the raw material charging device 120 may cover the upper portion of the charging chute 122 to prevent the raw material or dust from scattering. A hood 126 may be included. The dust collecting hood 126 is connected to the charging chute 122 so as to communicate with the inside of the charging chute 122, and the dust collecting hood 126 may be connected to a dust collector (not shown) or a dust collecting duct 130 connected to the dust collector. . Accordingly, the inside of the dust collecting hood 126 and the charging chute 122 may have a lower pressure than the outside of the dust collecting hood 126 and the charging chute 122 by the suction force of the dust collector. Therefore, the dust generated when discharging the raw material from the belt conveyor 112 to the charging chute 122, and the dust generated when charging the raw material from the charging chute 122 to the storage 212 is a dust collection hood 126 or It is possible to suppress or prevent leakage to the outside of the charging chute 122 .

The charging chute 122 is connected to the raw material transport device 110, and may be formed in a hollow shape with upper and lower portions open so that the raw material is supplied to the upper part and the raw material is discharged to the lower part. The charging chute 122 may be formed in a cylindrical or polygonal column shape, and may be formed in a shape corresponding to the shape of the charging port 213 of the reservoir 212 . For example, when the charging port 213 of the reservoir 212 is circular, the charging chute 122 may be formed in a cylindrical shape, and when the charging port 213 of the reservoir 212 is rectangular, the charging chute 122 ) may be formed in a rectangular column shape. The charging chute 122 is formed to extend in the vertical direction, and at least a portion thereof is bent toward the side where the reservoir 212 is formed, or it may be inclined downward toward the side where the reservoir 212 is formed. . The upper portion of the charging chute 122 may be fixedly installed on one side of the raw material transport device 110, for example, the support frame 112a, and the lower portion of the charging chute 122 may be disposed to be spaced apart from the charging surface E. Through this configuration, the charging chute 122 may move in the moving direction of the belt conveyor 112 together with the belt conveyor 112 .

The charging chute 122 may have a transverse cross-sectional area, in particular, a lower cross-sectional area of the charging chute 122 from which the raw material is discharged to be smaller than the area of the charging port 213 of the reservoir 212 . Accordingly, when the raw material is charged from the charging chute 122 to the reservoir 212 , the raw material collides with the inner surface or the screen 214 of the reservoir 212 , and the raw material enters the charging surface E around the charging port 213 . Dust may be generated by escaping and accumulating or scattering. Therefore, by forming the cover portion 124 having a larger area than the cross-sectional area of the charging chute 122 at the lower portion of the charging chute 122, for example, at the lower end, raw materials or dust are prevented from moving far around the charging port 213. can In this case, the cover part 124 may be formed to have an area larger than the cross-sectional area of the charging chute 122 , and to have an area smaller or larger than the area of the charging hole 213 . The cover portion 124 may be formed in a hollow shape with an open lower portion, and may be formed in a rectangular column shape with an open lower portion as shown in FIG. 2 , and may have an open lower portion according to the shape of the charging port 213 . It may be formed in a cylindrical shape or a cone shape. Hereinafter, the moving direction of the charging chute 122 in the cover part 124 is referred to as a longitudinal direction, and a direction crossing the longitudinal direction is referred to as a width direction.

The cover part 124 is fixedly installed on the lower part of the charging chute 122, and may be formed of the same or similar material as the charging chute 122, for example, a metal material. When the charging chute 122 is moved to charge the raw material, the cover 124 moves together with the charging chute 122. When the cover 124 formed of a metal material contacts the charging surface E, noise is generated. However, if it collides with a falling object, it may be damaged or deformed. Therefore, the cover portion 124 is preferably formed to be spaced a predetermined distance from the charging surface (E).

The removal unit 140 may be connected to the cover unit 124 to be movable in the vertical direction, and a part thereof may be connected to the cover unit 124 to be movable freely. The removal unit 140 may be connected to both sides of the cover portion 124 in the moving direction of the charging chute 122, for example, the front and the rear in the moving direction of the charging chute 122, respectively. While the removal unit 140 moves together with the charging chute 122 and the cover 124, the charging chute 122 moves the falling object on the charging surface E of the moving path to the reservoir 212. can be loaded

The removal unit 140 includes a fixing member 142 connected to the cover part 124 and a contact member 146 for collecting falling objects by contacting the charging surface E and pressing the contact member 146 to the charging surface. A connection member 143 for connecting the load transmission member 144 to the load transmission member 144 and the fixing member 142 connected to the upper portion of the contact member 146 in order to contact (E) so as to be movable in the vertical direction. ) may be included.

The fixing member 142 may be connected to the outer surface of the cover part 124 . The fixing member 142 may be formed in a height direction of the cover part 124 . In addition, guide grooves 142a extending in the vertical direction may be formed in the fixing member 142 to move the contact member 146 in the vertical direction. The fixing member 142 may be formed of a high-strength metal material to stably support the connecting member 143 and the contact member 146 . At least two of the fixing members 142 may be installed to be spaced apart from each other along the width direction on the outer surface of the cover part 124 . This is because the contact member 146 is formed so as to extend in the width direction of the cover portion 124, if the contact member 146 is inclined to either side, it is impossible to sufficiently remove the raw material or the falling object on the charging surface (E). Because.

The connection member 143 may connect the load transmission member 144 and the contact member 146 to the fixing member 142 to be movable in the vertical direction. The connecting member 143 may include a guide protrusion 143a that is engaged with the guide groove 142a to move freely along the direction in which the guide groove 142a extends. The connection member 143 may be formed of a metal material capable of stably supporting the load transmission member 144 and the contact member 146 .

The load transmitting member 144 serves to transmit a load or force to the connecting member 143 so that the guide protrusion 143a of the connecting member 143 can move along the guide groove 142a of the fixing member 142 . can do. In addition, the load transmission member 144 may serve to press the contact member 146 so that the contact member 146 can be sufficiently in close contact with the charging surface (E). Accordingly, the load transmission member 144 may be manufactured using a material having a higher specific gravity than the contact member 146 , or may be manufactured to be heavier than the weight of the contact member 146 . Alternatively, the load transmission member 144 can move the connecting member 143 from the fixing member 142, and the contact member 146 may be manufactured to have a sufficient weight to be in close contact with the charging surface (E). can As will be described later, the contact member 146 may be formed of an elastic material such as rubber or silicone, and the load transmission member 144 may be formed of a metal material such as iron having a higher specific gravity than the contact member 146 . . The load transmission member 144 may be formed to have a horizontal portion 144a extending in the width direction of the cover portion 124 and a bent portion 144b bent outwardly of the cover portion 124 . Alternatively, the load transmission member 144 may be formed in a bar shape to support the contact member 146 in the width direction of the cover part 124 . The load transmitting member 144 may be connected to the connecting member 143 and may be formed in various shapes as long as it can apply a load to the contact member 146 . The load transmitting member 144 may be fastened or connected to the connecting member 143 through a fastening member 148 such as a bolt or the like.

The contact member 146 may be connected to a lower portion of the load transmission member 144 . The contact member 146 may be connected to the load transmission member 144 by various methods such as fitting and fusion bonding. The contact member 146 may be formed in a plate shape extending in the width direction and the height direction of the cover part 124 . The contact member 146 may be formed to be flat, or may be formed to be bent outwardly of the cover part 124 . That is, the contact member 146 has a horizontal portion 146a extending in the width direction of the cover portion 124 and the outside of the cover portion 124 on both sides of the horizontal portion 146a, for example, of the charging chute 122 . It may include a bent portion 146b bent backward in the moving direction. In this case, the horizontal portion 146a and the bent portion 146b may be disposed to have an angle between more than 90° and less than 180° or about 100° to 150°. The contact member 146 may be formed to have an approximately 'C' shape by the horizontal portion 146a and the bent portion 146b. The reason for forming the contact member 146 in such a shape is to increase the suction efficiency of the member 149 to be described later. The contact member 146 has good adhesion to the charging surface E, and may include an elastic material that is not damaged when it collides with an obstacle such as a falling object. For example, the contact member 146 may be formed of rubber, silicone, or the like. This contact member 146 is in contact with the charging surface (E) during the movement of the charging chute 122 or the belt conveyor 112, and the falling object on the charging surface (E) is the charging chute 122 or the belt conveyor 112. can be moved in the direction of movement.

5 is a bottom view showing a modified example of the raw material charging apparatus according to an embodiment of the present invention, and shows an example in which the shape of the contact member 146 is modified.

The contact member 146 has a horizontal portion 146a extending in the width direction of the cover portion 124, and the cover portion 124 on both sides of the horizontal portion 146a, for example, in the direction of movement of the charging chute 122. It may include a bent portion 146b bent forward. In this case, the horizontal portion 146a may be formed to have a length equal to or smaller than the length of the charging port 213 , and the bent portion 146b may be formed to extend outside the cover portion 124 . If the bent portion 146b is formed in such a shape, when the charging chute 122 is moved, the outer charging surface E of the cover portion 124 from the rear of the charging chute 122 by the bent portion 146b. Raw materials or falling objects may be collected. In addition, since the bent portion 146b has an inclined surface formed on the inner surface, the raw material or falling object collected by the bent portion 146b moves toward the horizontal portion 146a and moves to the reservoir 212 by the horizontal portion 146a. can be reloaded.

On the other hand, the vertical length (L0, see Fig. 6 (a)) of the contact member 146, for example, the height may be formed to be longer than the distance (H0) between the cover portion 124 and the charging surface (E). The height L0 of the contact member 146 may vary depending on the vertical length of the fixing member 142 or the installation position of the fixing member 142 , but the height of the contact member 146 is at least the lower end of the cover part 124 . It may be formed to be longer than the distance (L0) between the charging surface (E). Alternatively, the height L0 of the contact member 146 is at least between the length Lc of the contact member 146 overlapping the cover part 124 in the vertical direction and the lower end of the cover part 124 and the charging surface (E). It may be formed to have a length (H0+Lc) that is the sum of the distances (H0). This is so that even if the lower end of the contact member 146 is worn, the contact member 146 is lowered to maintain a state in which the lower end is in contact with the charging surface (E).

6 is a view conceptually showing the operating state of the removal unit, and schematically illustrates the structure of the removal unit to explain the operating state of the removal unit.

6 (a) and 6 (b) show the operating state of the connecting member 143 and the fixing member 142. For example, as shown in (a) of Figure 6, when the distance between the cover portion 124 and the charging surface (E) is H0, the lower portion of the contact member 146 is in contact with the charging surface (E) can be placed. And as shown in (b) of Figure 6, when the distance between the cover portion 124 and the charging surface (E) increases to H1 (H0 + h) by the height change (h) of the charging surface (E), While the lower portion of the contact member 146 is maintained in contact with the charging surface E, the connection member 143 is descended from the fixing member 142 . At this time, the connection member 143 is the loading surface (E) by the load of the connection member 143 and the contact member 146 or the load of the connection member 143, the contact member 146, and the load transmission member 144, It descends from the fixing member 142 by a distance h corresponding to a height change h of .

Figure 6 (c) shows the operating state of the connecting member 143 and the fixing member 142 when the lower or lower end of the contact member 146 is worn. As shown in (a) of FIG. 6 , the initial vertical length of the contact member 146 , for example, the initial height of the contact member 146 is referred to as L0. When the process of charging the raw material into the reservoir is repeatedly performed, the lower end of the contact member 146 is worn due to friction with the charging surface E, and the height of the contact member 146 is shown in FIG. As shown, it is shortened to L1. As such, when the contact member 146 is worn, the connecting member 143 movably connected to the fixing member 142 is loaded with the connecting member 143 and the contact member 146 , or the connecting member 143 , the contact member. (146) and the load of the load transmission member (144) is lowered. And the lower end of the contact member 146 can maintain the state in contact with the charging surface (E) regardless of the height change due to wear.

As such, the contact member 146 is movably connected to the cover portion 124 through the connecting member 143 and the fixing member 142, and the height change of the charging surface E, for example, the bending of the charging surface E In response to a change in the length of the contact member 146, it is possible to maintain a state in continuous contact with the charging surface (E).

On the other hand, when the charging chute 122 or the belt conveyor 112 moves, the contact member 146 moves in a state in contact with the charging surface (E), and the intestines around the charging port 213 of the reservoir 212 are moved. You can collect and move the falling objects piled up on the elevation (E). In the process of moving the falling object collected by the contact member 146 as described above, particles having a very small particle size among the falling objects may scatter to generate dust. Therefore, in order to prevent dust from being generated in the falling objects collected by the contact member 146, to remove the raw material remaining on the charging surface E at the rear of the contact member 146 with respect to the moving direction of the charging chute 122. A suction pipe 149 may be installed for At this time, one side of the suction pipe 149 is connected to the charging chute 122 so as to communicate with the inside of the charging chute 122, and the other side is the charging surface ( It can be arranged to face E). And the suction pipe 149 may be supported by a structure such as the cover part 124 or the charging chute 122 by the support body 150 . Although described above, the inside of the charging chute 122 has a lower pressure than the outside of the charging chute 122 by the suction force of the dust collector. Accordingly, fine particles or dust not removed from the charging surface (E) by the contact member 146 are sucked through the suction pipe 149 and introduced into the charging chute 122, so that the charging surface E around the reservoir 212 ) to suppress or prevent the generation of dust.

7 is a perspective view showing a raw material charging device according to a modified example of the present invention.

Since the raw material charging apparatus according to a modified example of the present invention has a configuration similar to that of the above-described embodiment, a description of the same configuration as that of the above-described embodiment will be omitted.

The removal unit 140 includes a fixing member 142 connected to the cover part 124, a contact member 146 for collecting falling objects by contacting the charging surface E, and a contact member ( It may include a connection member 143 for connecting the 146 to be movable in the vertical direction.

The contact member 146 may be connected to the connecting member 143 by a fastening member 148 . At this time, the contact member 146 may be formed thicker than the lower side in contact with the upper side connected to the connecting member 143 (E). For example, the thickness of the upper side of the contact member 146 may be 1.5 to 3 times greater than the thickness of the lower side. In this case, a step or an inclined surface may be formed on the surface of the contact member 146 facing the cover portion 124 or on the opposite surface thereof. As described above, when the upper side of the contact member 146 is formed to be thicker than the lower side, for example, in the upper and lower narrow shape, the upper side of the contact member 146 serves as the load transmitting member 144 described in the embodiment. Accordingly, the connection member 143 may move freely in the fixing member 142 , and the contact member 146 may maintain a state in contact with the charging surface (E).

The connecting member 143 may be formed in the same shape as in the embodiment described above, or may be formed of a guide roller 143b inserted into the guide groove 142a and movable along the extending direction of the guide groove 142a. have. When the connecting member 143 is formed of the guide roller 143b as described above, it is possible to reduce frictional resistance that may occur between the guide roller 143b and the fixing member 142 .

In the above-described embodiment, in order to remove the raw material not removed by the contact member 146, a suction pipe 149 is installed in the charging chute 122. At this time, since the suction pipe 149 is only partially suctionable in the width direction of the cover part 124 , the raw material may remain on the charging surface E even after suctioning. Therefore, the extension pipe 151 extending in the width direction of the cover part 124 or the horizontal part 146a of the contact member 146 may be connected to the lower part of the suction pipe 149 in the extending direction. In addition, a slit-shaped suction port 153 extending in a direction in which the extension tube 151 extends may be formed in the extension tube 151 . Through this configuration, it is possible to more efficiently remove fine particles or dust remaining on the charging surface E without being removed by the contact member 146 .

The embodiments and modified examples described above can be combined with each other, and various modifications can be made through the mutual combination.

Hereinafter, a method of loading a raw material into a storage device using a raw material charging device according to an embodiment of the present invention will be described.

8 and 9 are diagrams illustrating a process of loading a raw material into a reservoir by a raw material charging method according to an embodiment of the present invention.

The raw material charging method according to an embodiment of the present invention, the process of providing a contact member 146 movable in the vertical direction on the outside of the charging chute 122, and the charging chute 122 on the upper portion of the reservoir 212 The process of contacting the contact member (!46) by its own weight to the charging surface of the upper outer side of the reservoir 212, and the process of charging and dropping the raw material from the charging chute 122 to the reservoir 212, , moving the charging chute 122 and the contact member 146 in the horizontal direction, and using the contact member 146 to move the raw material accumulated on the charging surface out of the falling path of the raw material.

In order to charge the raw material into the storage 212 , the raw material may be discharged from the yard and transported toward the storage 212 through the belt conveyor 112 . At this time, by moving the support frame 112a of the belt conveyor 112 toward the storage 212 for charging the transported raw material, the charging chute 122 connected to the belt conveyor 112 is stored for charging the raw material. It may be disposed on the group 212 . In this case, the cover part 124 connected to the lower part of the charging chute 122 is to cover a portion of the charging surface (E) of the charging port 213 or the charging port 213 and its surroundings of the reservoir 212. can be placed. And in the removal unit 140 connected to the cover unit 124, for example, the contact member 146, the connecting member 143, the load transmitting member 144, and the contact member 146 are subjected to a load, that is, by gravity. It is possible to maintain a state in contact with or in close contact with the charging surface (E) around the charging port 213.

The raw material transported through the belt conveyor 112 is discharged to the charging chute 122 connected to the belt conveyor 112, as shown in FIG. (212) can be loaded into the interior. At this time, some of the raw materials may deviate from the falling path and accumulate on the charging surface (E), and some of the raw materials collide with the inner surface of the screen 214 or the reservoir 212 installed in the charging port 213 of the reservoir 212. It may flow out of the charging surface (E) and the cover portion (124). In this way, the raw material, for example, a falling object deviated from the falling path, is accumulated on the charging surface (E) inside the cover part 124 as well as the charging surface (E) outside the cover part 124 .

When the raw material is charged into the reservoir 212 , the support frame 112a of the belt conveyor 112 may be horizontally moved to load the raw material into the adjacent reservoir 212 or another reservoir 212 . When the support frame 112a is moved in this way, the charging chute 122 connected to the support frame 112a is moved in the moving direction of the support frame 112a. In this process, the cover part 124 connected to the lower part of the charging chute 122 and the removal part 140 connected to the cover part 124 are also supported by the support frame 112a and the charging chute 122 in the moving direction. will move to The contact member 146 of the removal unit 140 maintains a state in which the connection member 143, the load transmission member 144, and the contact member 146 are in contact with or in close contact with the charging surface E by the load. Accordingly, as shown in Figure 9, the raw material, for example, a falling object in the charging surface (E) around the charging port 213 is collected by the contact member 146, while moving in the direction of movement of the charging chute 122. . At this time, the falling object accumulated on the charging surface (E) around the inside of the cover part 124, that is, the charging port 213, is the cover part 124 with respect to the moving direction of the support frame 112a or the charging chute 122. It can be collected and moved by the contact member 146 installed at the rear. The falling objects collected by the contact member 146 in this way may be introduced into the reservoir 212 in which the raw material is charged while the charging chute 122 moves. In addition, when both sides of the contact member 146 are bent forward with respect to the moving direction of the charging chute 122, the raw material outside the cover part 124 can also be collected and introduced into the reservoir 212. have. And after the falling object flows into the reservoir 212 , some of the falling objects having a very small particle size do not flow into the reservoir 212 by the contact member 146 , but may remain on the charging surface E. In this way, the falling object remaining on the charging surface (E) is introduced into the charging chute 122 through the suction pipe 149 installed at the rear with respect to the moving direction of the charging chute 122, and can be removed from the charging surface (E). . On the other hand, the raw material in the front with respect to the moving direction of the charging chute 122 may be collected by the contact member 146 and reloaded into the reservoir installed in the front with respect to the moving direction of the charging chute 122 .

When charging the raw material in this way, the contact member 146 may be worn due to contact with the charging surface (E). Since the connection member 142 supporting the contact member 146 is not fixed to the fixing member 142, but is connected to be freely movable, the contact member 146 is always in contact with the charging surface E. state can be maintained. Thus, unless the contact member 146 is severely worn, it is possible to efficiently remove the raw material flowing out to the charging surface (E) when the raw material is charged by continuously maintaining the state in contact with the charging surface (E) due to the load.

As such, although specific embodiments have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims to be described below as well as the claims and equivalents.
