Description

TECHNICAL FIELD

[0001] The present invention relates to a so-called bulk cargo container for storing and transporting wood pellet particles, powder-like cargo such as grains. BACKGROUND

[0002] The bulk cargo container is a container for storing or transporting powder-like cargo such as wood pellet particles from a loading port at the top (ceiling portion) or discharging from a discharge port provided in one portion such as a side wall after being loaded in this state on a truck or the like. The wood pellet particles or the like are poured into the inside of the bulk cargo container (container vessel) from a hopper provided at, for example, a port through the loading port, and then discharged by opening the discharge port, tilting the container, or the like.

[0003] A door is provided at the discharge port so as to be opened and closed, and a cover for preventing rain or the like from entering is provided at the loading port at the top. As the cover of the loading port, a door of a hatch-like hasp door type (rotary type) is generally provided. The door of the hasp door type is easy to provide a sealing material or the like for preventing rain from entering.

[0004] A container in which a cover of a sliding door type (sliding opening and closing type) is provided at the loading port at the top is shown in the following Patent Document 1. In addition, in Patent Document 2, a device for opening and closing a top opening of a container in which a liquid is stored is disclosed, and a cover of a sliding door type is provided at the opening. In this Patent Document 2, it is described that the cover of the sliding door type is more advantageous than the cover of the hasp door type when a space between the opening and a hopper above cannot be ensured.

[0008] Patent Document 2: Japanese Utility Model No. 3204506 SUMMARY

[0009] PROBLEMS TO BE SOLVED BY THE INVENTION

[0010] The bulk cargo container is generally provided with a hopper for feeding the powder or granular cargo from above. Also, the height of the loading port of the bulk cargo container is set to the height of the lower end of the hopper so as to prevent the powder or granular cargo from scattering. Therefore, in order to load the bulk cargo container mounted on a truck or the like to the position directly below the hopper and open the loading port to receive the powder or granular cargo, it is more advantageous to use a cover of the sliding door type in which the cover slides horizontally, rather than a cover of the hinged door type in which the door is rotated upward, as shown in Patent Documents 1 and 2. In the case where the door of the hinged door type is provided to the loading port, the following steps are required: the truck is stopped in front of the hopper, the door of the bulk cargo container is opened, the truck is moved forward so that the loading port is positioned directly below the hopper to receive the powder or granular cargo, and then the truck is moved slightly forward from the position directly below the hopper to close the door. In contrast, in the case where the cover of the sliding door type is provided to the loading port, it is not necessary to stop the truck in front of the hopper or slightly in front of the hopper.

[0011] However, in the examples of Patent Documents 1 and 2, the worker (or the driver of the truck) needs to climb onto the top of the container in order to open and close the cover of the loading port. The reason for this is that the cover is a cover which is directly operated by hand to open and close.

[0012] Also, the examples in which the loading port is sufficiently long in the longitudinal direction of the container are not shown in Patent Documents 1 and 2. The powder or granular cargo fed from the hopper or the like forms a conical pile having a slope corresponding to the repose angle of the powder or granular body in the container, and therefore, in the case where the loading port is provided only in the vicinity of the central portion of the bulk cargo container, a large amount of space in the interior space above the front and rear portions of the container corresponding to the longitudinal direction of the container is left as a portion which cannot be filled with the cargo. This problem can be solved by providing a plurality of loading ports in the longitudinal direction of the container, but when the number of loading ports is increased, the burden on the worker who climbs onto the top of the container to open and close the cover is increased.

[0013] In view of the above problems, the present application provides a bulk cargo container in which the cover of the loading port can be opened and closed without the worker climbing onto the top of the container, and in which the space which cannot be filled with the powder or granular cargo can be reduced.

[0014] Solution for solving the problem

[0015] The bulk cargo container of the present application receives the powder or granular cargo fed into the container (the box-shaped portion of the container) from the loading port provided to the top, the loading port being covered by a cover of the sliding door type (the sliding type) which is horizontally reciprocated to open and close the loading port, the cover being reciprocated in conjunction with the operation of the operation member provided to the side portion of the container.

[0016] The bulk cargo container is provided with a horizontally moving door type cover at the top of a loading port, so that as described above, when the bulk cargo container is positioned directly below a hopper or the like supply device, and the powder or granular cargo is received through the loading port, the cover can be opened and closed at the position of the lower end opening of the hopper directly below the hopper. Further, the cover is linked to move when an operating member provided at the side of the container is moved, and performs reciprocating movement, so that the loading port can be opened and closed by moving the operating member at the side of the container even if the worker does not climb onto the top of the container. From these points, when the bulk cargo container of the present application is used, the cargo can be efficiently and safely received from the hopper.

[0017] In the bulk cargo container of the above-described application, preferably,

[0018] The loading port has an opening in a long rectangular shape in the length direction of the container (the direction of the longer side in the horizontal dimension of the container), that is, the dimension of the opening in the length direction of the container is longer than the dimension in the width direction of the container, and the cover is horizontally (including substantially horizontally) reciprocated in the width direction of the container to open and close the loading port.

[0019] The cover is preferably formed of one plate capable of covering the entire loading port, or two plates capable of covering the entire loading port by bringing and abutting the edge portions opposite to each other, and opening the loading port by separating the edge portions from each other.

[0020] The loading port is a so-called longitudinal opening in the length direction of the container as described above, so that the powder or granular cargo can be received from the hopper or the like not only near the central portion of the container, but also near both end portions in the length direction. Therefore, even in each of the front and rear portions in the length direction of the container, the cargo accumulated on the inclined surface forming a repose angle in the container can reach the top, and the space in the container can be effectively utilized, and a large amount of cargo can be loaded.

[0021] In the case where the loading port is made long in the longitudinal direction as described above, the cover body that covers the loading port is preferably made to reciprocate in the width direction of the container vessel to open and close the loading port as described above. When the cover body that covers the loading port reciprocates in the longitudinal direction of the container vessel, since the loading port is long in the longitudinal direction, the cover body can greatly protrude from the container vessel in the front and back directions (either of the longitudinal directions of the vessel) when the loading port is opened. When the cover body greatly protrudes from the container vessel, the cover body can come into contact with a part of a truck that carries the container, a nearby device, a machine, and thus can not be able to smoothly load the cargo. If the cover body is made to reciprocate in the width direction of the container vessel, the above-described problem is less likely to occur even if the loading port is long in the longitudinal direction. Further, when the cover body is made of the one or two plates as described above, the cover body can cover the loading port and prevent rainwater from entering the container vessel.

[0022] The bulk cargo container as described above, in which the loading port is covered by the door-type cover body that reciprocates in linkage with the operating member provided to the side portion, is preferably characterized in that:

[0023] the cover body is movable along guide rails provided near both ends in the longitudinal direction of the loading port, and

[0024] the cover body is linked to the operating member via a transmission mechanism including a rope (cable, steel, cord, or the like) that passes through the side portion and the top portion of the container vessel and a pulley to which the rope is attached, and thus reciprocates in linkage with the operating member.

[0025] Figure 1 、 Figure 3 An example of the bulk cargo container thus configured is shown in FIGS. 1 to 3. The cover body 6 that is movable along the guide rails 14 is linked to the operating member 20 via the transmission mechanism 10 including the cable 11 and the pulleys 12 and 12a.

[0026] The cover body is movable along the guide rails, and thus the cover body can reciprocate in the fixed range in which the loading port can be covered on the top portion of the container vessel to open and close the loading port. Further, the cover body is linked to the operating member including the rope and the pulley, and thus reciprocates in linkage with the operating member when the operating member provided to the side portion of the container vessel that is located far away is moved. When the transmission mechanism including the rope and the pulley is used, the cover body is less likely to be restricted in the direction of movement and the position and the direction of movement of the operating member in linkage therewith, and thus the bulk cargo container that is easy to use can be configured.

[0027] In the bulk cargo container using the rope or the like as described above, more preferably,

[0028] The operating component is located on only one side wall surface of the container.

[0029] The pulleys and ropes of the transmission mechanism are configured such that the force exerted when the operating member is moved is transmitted via the rope to two points on the cover that are separated in a direction perpendicular to the direction of movement of the cover, as a force that causes the cover to reciprocate.

[0030] exist Figure 3 This structure is used in the illustrated bulk container 1. When tension is applied to any point of the steel cable 11 through the operating member 20, the movable pulleys 12a in the two separated positions are simultaneously pulled downward as shown in the figure, causing the cover 6 to move.

[0031] When the operating components located on the side of the container are respectively positioned on two opposite sidewall surfaces, it facilitates reliable reciprocating movement of the cover (i.e., opening and closing the loading port). This is because even if the cover is long and its movement along the guide rail is not smooth, it is easy to move the cover by simultaneously operating the operating components on both sidewall surfaces. However, when the operating components are separately located on the two sidewall surfaces, two operators are required to operate them simultaneously.

[0032] In this regard, in the bulk cargo container, the operating components are only located on one side wall surface of the container, so even one worker can move the cover back and forth.

[0033] Furthermore, because the force for moving the operating member is transmitted via rope to two points on the cover that are separated in a direction perpendicular to the direction of movement of the cover, the rope pulls on these two points on the cover to move the cover when the operating member is moved. Therefore, even if one worker moves the operating member on one side wall surface of the container, the cover can be reliably moved in the same way as if the operating member were installed on two side surfaces that are opposite to each other.

[0034] More preferably, in the bulk cargo container,

[0035] When the filling port is closed by the cover, the top edge of the cover (the edge on the moving destination side when the filling port is closed) and the opening edge of the filling port are aligned, or the top edges of the two opposing plates of the cover are aligned.

[0036] Between the top edge of the mating cover and the opening edge of the filling port, or between the opposing top edges of the two plates of the cover, an elastic sealing material is installed on one edge, and a metal member is provided on the other edge (the side that mates with the edge of the aforementioned one) pressing against the end face of the elastic sealing material in a horizontal direction.

[0037] In Figure 5 the above-mentioned two edge portions and the elastic sealing material, metal member, etc. are exemplified. Reference numeral 31a is the elastic sealing material, and reference numeral 31b is the metal member which presses the elastic sealing material 31a.

[0038] In the above-mentioned bulk cargo container, when the loading port is closed by the lid, the penetration of rainwater can be effectively prevented. The reasons are as follows: 1) In the bulk cargo container which is provided with a transmission mechanism such as a mobile operation member which transmits force to the lid via a rope at two points, when the operation member is moved, the lid is moved since the force acts on the lid at two points, and the top edge portion of the lid is butted against the opening edge portion of the loading port, or the top edge portions of the two plates of the lid are butted against each other. 2) The force acts on two points, so the lid is reliably moved, and the force which butts the edge portions against each other is uniformly and strongly applied to the entire length of each edge portion. 3) In the butted edge portions, the elastic sealing material is installed in one edge portion, and the metal member is installed in the other edge portion, so in the butted state, the metal member uniformly and strongly presses the elastic sealing material over the entire length of each edge portion, and the penetration path of rainwater is blocked. In this state, when the movement of the lid is stopped (locked), the penetration of rainwater can be continuously prevented, and water can be prevented from entering the container.

[0039] In the above-mentioned bulk cargo container in which the loading port is covered by the lid which reciprocally moves in linkage with the operation member of the side portion, the following features are preferably provided:

[0040] The operation member is provided only on one side wall surface of the container,

[0041] Linear guide members are arranged in parallel to each other near both end portions in the length direction of the loading port, and a moving block in which a rotating body is built is installed in each guide member (that is, a low-friction linear guide device such as a linear bushing, a linear guide, etc. is arranged in parallel to the top portion of the container at an appropriate position),

[0042] The lid is movable by being installed in the moving block, and the operation member (which extends to the side portion of the container) is linked to a portion (one end portion in the length direction) of the lid, so the lid moves in linkage with the operation member, and reciprocally moves as described above.

[0043] In Figure 6 , Figure 8An example of a bulk cargo container thus configured is shown in FIG. 1. A linear guide member 41 is installed with a built-in rotating body in a moving block 42, and the cover 6 is installed in the moving block 42. Further, an operation member 50 provided only on one side wall surface is fixedly linked to a portion (frame 6f) of the cover 6.

[0044] In such a bulk cargo container, the cover can be smoothly reciprocated by the low-friction moving guide action by the two linear guide members disposed near both end portions in the length direction of the loading port and the moving block with the built-in rotating body installed in the guide member. Further, when the operation member fixed to a portion of the cover is moved, the cover is reciprocated together with the operation member. Since the operation member is provided only on one side wall surface of the container, even one worker can reciprocate the cover.

[0045] In the moving, the cover is forced only from the side of the portion of the operation member, and thus it can also be assumed that in the case of moving along two ordinary guide rails with an interval, uneven force due to friction acts, and the moving is not necessarily smooth. However, in the bulk cargo container described above, two sets of low-friction linear guide devices including the moving block with the built-in rotating body are used, and thus the cover can always be smoothly moved even though it is forced only from the side of the portion.

[0046] As described above, in the bulk cargo container in which the low-friction linear guide device is provided near both end portions of the loading port, it is preferable that

[0047] The cover is installed so as to be fixed with respect to the moving block installed in one of the guide members disposed near both end portions of the loading port and freely movable with respect to the moving block installed in the other guide member.

[0048] In the bulk cargo container described above, the cover is installed so as to be fixed with respect to the moving block installed in one of the guide members disposed near both end portions of the loading port and freely movable with respect to the moving block installed in the other guide member. Figure 9 The bulk cargo container shown in the example also adopts this configuration. The moving block 42 on one side (left side in the drawing) is bolted to the cover 6 (frame 6f), and the moving block 42 on the other side (right side in the drawing) is installed with a bolt-shaped link pin 44, and the cover 6 is linked to the link pin 44 with a gap corresponding to the gap in which it can float around and up and down.

[0049] The linear guide member is provided near both end portions of the loading port, and thus two are generally provided in parallel with an interval of several meters or more on the top of the container. Thus, it is possible that the parallelism of the two is reduced due to installation errors and deformation, thermal expansion, and the like of the container.

[0050] However, in the case where the lid is mounted to the moving block on the guide member as described above, the lid can smoothly reciprocate even if the parallelism of the guide members is not high. This is because the moving block of the lid on the guide member of one of the two (the other one) can float as described above, and thus the offset of the parallelism is eliminated without problem by the corresponding float, and the movement of the lid along the two guide members does not malfunction.

[0051] In the bulk cargo container in which the linear guide device with low friction is used and the operating member is provided on only one side as described above, it is also preferable to have the following features.

[0052] When the lid closes the loading port, the top edge portion of the lid (the edge portion on the side that becomes the destination of movement at the time of closing) and the opening edge portion of the loading port are butted, or become a state in which the top edge portions of the two plates of the lid are butted to each other,

[0053] An upward metal member is provided to both edge portions, and a water seal cover having an elastic sealing material on the lower surface is installed near one of the edge portions, the water seal cover is moved by the operating member provided to the side portion of the container, and the upward metal member of both edge portions presses the elastic sealing material from above.

[0054] Figure 10 The configuration of both edge portions and the water seal cover and the like butted as described above is exemplified in FIG. 6. Reference numeral 61 is a water seal cover, and an elastic sealing material 62 is provided on the lower surface, and the elastic sealing material 62 is pressed from above to the upper end portion of a metal member 63.

[0055] When configured as above, rainwater can be effectively prevented from penetrating when the loading port is closed by the cover. The reasons are as follows. That is, 1) when the operating member is moved to close the loading port, a part of the force is transmitted to the cover, the cover moves, the top edge portion of the cover and the opening edge portion of the loading port are butted, or the top edge portions of the two plates of the cover are butted. 2) The cover moves smoothly by the low-friction straight guide means, so that in the butted state, a large gap is not generated between the entire or partial edge portions, but only a part of the cover is linked to the operating member, so that on the side far from the operating member where the force is difficult to be received, it is difficult to make the edge portions completely close to each other. 3) However, even if there is a little gap between the edge portions of the two, with the configuration described above, the upward metal members are provided at the edge portions, the elastic sealing material of the water seal is pressed from the upward direction to the metal members, so that rainwater can be reliably prevented from penetrating between the butted edge portions. 4) The operation of pressing the elastic sealing material of the water seal to the metal members can be easily performed from the side of the container by the operating member. When the movement of the cover and the water seal is stopped (locked) in the state that the elastic sealing material is pressed to the metal members, rainwater can be continuously prevented from penetrating, and water can be kept from entering the container.

[0056] In the bulk cargo container in which the loading port is provided with the openable and closable cover of the sliding door type, more preferably,

[0057] A support rail capable of reciprocally moving the cover and supporting the weight of the cover is installed at a position across the loading port, and on the other hand, a wheel that rolls on the support rail is installed at the lower portion of the cover,

[0058] The support rail is in a shape in which the central portion is protruded upward.

[0059] The support rail is installed at a position across the loading port, that is, a position between the two guide rails or the straight guide members described above. Also, the cover is reciprocally moved in a straight line, so that the support rail is provided in parallel with the guide rails or the guide members. In Figure 4 or Figure 9 Examples of the support rail and the like are shown in FIGS. 6a to 6g. Reference numerals 16 and 46 are support rails, and reference numerals 6a and 6g are wheels that roll on the support rails.

[0060] In the case of a long opening such as a continuous long opening in the longitudinal direction of the loading port, as described above, only the guide rails or the straight guide members are disposed near the both end portions of the loading port, and the central portion of the cover is easily bent downward or deformed. In view of this, if the support rail is installed at a position across the loading port as described above, and the wheel of the lower portion of the cover is made to run along the support rail, the cover is favorably supported as a whole, and deformation thereof is prevented.

[0061] The support rail is provided at a position across the loading port, so powder and granular cargo dropped into the container from a hopper or the like inevitably falls on the support rail. However, since the support rail is installed in the shape of a central portion protruding upward, powder and granular material does not accumulate, adhere, or the like on the rail, hindering movement of the cover.

[0062] The bulk cargo container of the present application preferably has,

[0063] At a position directly below the loading port in the container, there is provided an inclined plate or impeller capable of changing the falling direction of powder and granular cargo dropped.

[0064] Examples of the inclined plate or impeller installed are shown in Figure 11

[0065] When an inclined plate or impeller is provided directly below the loading port, powder and granular cargo dropped into the container from a hopper or the like spreads not only directly below the opening but also to the periphery. Normally, powder and granular cargo accumulates in the shape of a conical surface having a repose angle as described above, so in the case of falling directly below the hopper or the like, a large space in which cargo cannot be filled remains at the top of the container. However, when the cargo is caused to fall and spread to the periphery by the action of the inclined plate or the like as described above, the space in which cargo cannot be filled can be reduced, and the internal space of the container can be effectively utilized.

[0066] With regard to the above bulk cargo container in which the loading port is covered by a door-type cover and the cover is linked to an operating member of the side portion to move reciprocally,

[0067] Preferably, the operating member is provided at a position near either side portion of the ceiling portion of the container, rather than at the side portion of the container.

[0068] Examples of the bulk cargo container thus configured are shown in Figure 12 Figure 14 and the like. The operating member 80 is provided at a position near the side portion corresponding to one end portion in the length direction of the ceiling portion of the container 3. When the operating member 80 is moved in the width direction of the container 3, the cover 6 also moves in the same direction, so the loading port 5 can be opened and closed.

[0069] ​​When the operating component that reciprocates the cover is located on the side of the container (on the side surface of the end of the container along its length or on another side surface), as described above, the operation is easy to perform. However, the operation is also easy to perform when the operating component is located in the top of the container, near either side. This is because as long as a simple work platform is provided that allows access to the side, the operator can use this platform to operate the operating component located near either side without having to climb onto the top of the container.

[0070] The cover that can be opened and closed to cover the loading port is a sliding door type cover, and the cover can be operated even without climbing onto the top of the container. Therefore, using this bulk cargo container can efficiently and safely receive goods fed from the hopper.

[0071] In particular, the aforementioned operating component may be located above the discharge port for discharging the aforementioned goods on the side of the container or on the top of the container near the side with the aforementioned discharge port.

[0072] exist Figure 12 , Figure 14 In the example of a bulk cargo container, the operating component 80 is also located on the side of the container 3, near the outlet 8.

[0073] As described above, the operating component that causes the cover to reciprocate is preferably located on either the side (side wall surface) or the roof of the container, near the side. However, if located on the side of the container, it is best positioned above the outlet for discharging the aforementioned goods; if located in the roof, it is most advantageous to position it on the side of the roof near the outlet. This is because, with such an arrangement, the areas requiring operation can be concentrated in or near a single side of the container.

[0074] Bulk cargo containers, which handle powdery or granular goods, typically have a loading port in the top of the container and a discharge port on the lower part of one side (sidewall surface). Generally, there are no other operational parts. The discharge port is opened and closed using an operating lever mounted on the hatch. Therefore, by placing the operating mechanism for manipulating the loading port cover above or near the top of the side with the discharge port, the operational parts can be concentrated in one area. This centralized arrangement simplifies and efficiencies the operation of bulk cargo containers.

[0075] Invented bulk cargo container,

[0076] A plurality of partitions having a surface intersecting the longitudinal direction of the container and supported at the upper end portion are provided at positions other than the central portion in the longitudinal direction of the same container at upper positions in the container,

[0077] Preferably, the partition is a swingable partition that can only be displaced between a posture in which the lower portion is oriented in the vertical direction and a posture in which the lower portion is oriented toward the side opposite the central portion (the side on which the lower portion is distanced from the central portion).

[0078] In Figure 17 A bulk cargo container 4 having two partitions 90 in the container 3 is shown in FIG. 8. Each partition 90 can only be freely swung between a posture in which the lower portion is oriented downward and a posture in which the lower portion is swung toward the side opposite the central portion in the longitudinal direction of the container as shown by the dotted line.

[0079] When a powder or granular cargo is loaded into the container from the loading port, the cargo is piled in a conical shape as described above. Therefore, there are cases in which even if the cargo reaches the height of the loading port near the center, a large space remains at both ends in the longitudinal direction of the container. At this time, when the vehicle carrying the container is repeatedly driven slightly forward and backward and then stopped, the powder or granular cargo can be moved to the space, and then the cargo can be further loaded from the loading port.

[0080] In the case in which the powder or granular cargo is moved in the container in this way, when a partition that can only be swung to one side is disposed in the container, the above movement of the powder or granular cargo can be smoothly performed. This is because the partition that can only be swung to one side does not hinder the movement of the cargo to the side distanced from the central portion of the container (that is, the side on which the powder or granular cargo is difficult to pile and a space is easily formed), and on the other hand, hinders the movement of the cargo from the end portion side toward the central portion. That is, with the partition, the movement of the powder or granular cargo from the central portion toward the end portion side in the container can be promoted. Thus, the uneven piled state of the cargo can be quickly eliminated, and the capacity of the container to accommodate the cargo can be increased.

[0081] Effects of the Invention

[0082] With the bulk cargo container of the present application, the cover that covers the loading port can be opened and closed directly below the supply device such as a hopper, and a worker does not need to climb onto the top of the container in order to open and close the cover. Therefore, the opening and closing of the cover can be efficiently and safely performed, and the receiving work of the cargo from the hopper or the like can be smoothly performed.

[0083] The lid body can be appropriately moved to open and close the loading port by the operating member provided at an easily operated position such as the side portion of the container, as long as the lid body is moved reciprocally by being linked to the operating member through a transmission mechanism including a rope and a pulley. In the case where the force for moving the operating member is transmitted to the lid body through the rope at two places, the lid body is smoothly and reliably moved only by the worker moving the operating member from one place.

[0084] In the case where a low-friction linear guide device called a linear bushing, a linear guide, or the like is provided near both end portions of the loading port, and the lid body is moved using the action thereof, the lid body can always be smoothly moved reciprocally to open and close the loading port only by the operating member at one place.

[0085] The operating member for opening and closing the lid body covering the loading port at the top of the container is advantageous for efficiently and safely opening and closing the lid body, regardless of whether it is provided at the side portion of the container or at a position near either side portion of the ceiling portion of the container. This is because, in either case, the worker does not need to climb onto the top of the container to open and close the lid body. In particular, when the operating member is provided at a position above the side portion where the discharge port is provided or at the ceiling portion near the side portion, the bulk cargo container is configured to be easily operated because the places where the operation is required on the container are concentrated in the vicinity.

[0086] When a partition plate that can swing only to one side, i.e., a side away from the central portion, is appropriately provided at a position above the container, uneven accumulation of the powder and granular cargo can be easily eliminated, and the capacity of the container for accommodating the cargo can be increased.

[0104] exist Figures 1 to 5 The diagram illustrates a bulk cargo container 1 according to an embodiment of the present invention. The bulk cargo container 1 is a device for storing or transporting granular goods, such as wood pellets, received from the top and capable of being retrieved from the discharge port 8 at the bottom. Figure 1 (a) and (b) show the top and side views of bulk container 1.

[0105] The bulk cargo container 1 is mainly composed of a rectangular box-shaped container 3 made of metal or the like. It has a loading port 5 at the top and a discharge port 8 at the lower end along its length. A sliding door cover 6 is installed at the loading port 5, and a hinged door 9 is installed at the discharge port 8. It should be noted that the approximate dimensions of the container 3 shown in the illustration are approximately 6 meters long, 2.5 meters wide, and 3 meters high, but the invention is not limited to these dimensions.

[0106] The outlet 8 and the door 9 installed at the outlet 8 are configured in the same manner as conventional bulk cargo containers. That is, as... Figure 2As shown in the lower half, a metal door 9 is installed at the opening of the outlet 8, supported by a top hinge, and the lower part is equipped with a swing-opening and closing mechanism. The door 9 can be locked to the frame of the container 3 or unlocked using a locking lever 9a. The locking and unlocking using the locking lever 9a can be performed by operating the lever 9b.

[0107] like Figure 1 As shown in (a), the loading port 5 is a longitudinal opening (approximately 4.5 meters long and 1 meter wide) along the length of the container 3, located at the center of the container 3 in the width direction. A cover 6, made of metal plates or the like, is installed at the loading port 5 in a sliding door-like manner. The cover 6 consists of two plates joined together at the center of the container 3 to cover the entire loading port 5. The plates slide horizontally outwards from the center in the width direction, causing them to move and separate, thereby opening approximately the entire loading port 5.

[0108] like Figure 1 (b) or Figure 5 As shown, the cover 6 has multiple wheels 6a mounted on the lower surface of each plate. These wheels 6a are mounted on guide rails 14 and support rails 16 that are parallel to each other across the loading port 5, thereby enabling reciprocating movement in the width direction of the container 3. The guide rails 14 primarily guide the movement of the cover 6, while the support rails 16 support approximately the middle portion of the cover 6 to prevent deformation of the cover 6.

[0109] like Figure 4 As shown, the guide rail 14 and support rail 16 use devices with an upwardly protruding central portion. To facilitate movement along these, the wheels 6a provided on the cover 6 are drum-shaped devices capable of moving across the protruding portion. This prevents the wheels 6a from slipping off, and prevents the input of powdery or granular materials from adhering to or accumulating on the guide rail 14 and support rail 16, thus ensuring that the cover 6 always moves smoothly.

[0110] Furthermore, to prevent the cover 6 from detaching from the guide rail 14, such as Figure 4 As shown in the diagram, the pressing roller 17 installed on the container 3 is brought into contact with the upper surface of the edge of the cover 6.

[0111] exist Figures 1 to 5 In the example, as a method for driving the reciprocating movement of the cover 6, a manually operated component 20 is provided on one end side surface of the container 3 (see...). Figure 2 ), and through steel cable 11 and pulleys 12, 12a Figure 3The transmission mechanism 10 transmits the action of the operating component 20 to the cover 6. The mechanism is that when the operating component 20 is operated, pulling any steel cable 11 causes displacement of the steel cable 11 with the pulley 12 attached, thereby moving the cover 6 in a certain direction. It should be noted that, in order to protect the pulley 12 and other components from rainwater and to prevent rainwater from seeping into the loading port 5, as... Figure 1 As shown in (a) and (b), side covers 15 are installed at both ends of the top of the container 3 in the longitudinal direction.

[0112] exist Figure 2 The configuration of the operating member 20 is shown. A conduit 21 is installed on the end side surface of the container 3, and a traction member (not shown) connected to the steel cable 11 is inserted into the inside of the conduit 21 in a way that allows it to move up and down. An operating lever 22 is installed on this traction member and extends outward from a slit (not shown) formed on the side of the conduit 21. When either operating lever 22 is pulled downward by hand, the steel cable 11 connected to it can be pulled. It should be noted that the lever 22 can be fixed in position after operation.

[0113] The transmission mechanism 10, including the steel cable 11, is as follows: Figure 3 The configuration is shown. A steel cable 11, which can be pulled by the operating lever 22, is suspended from multiple fixed pulleys 12 on the container 3, and movable pulleys 12a on the frame that move integrally with each plate of the cover 6. Furthermore, the end of the steel cable 11 is connected to an anchor 13 fixed to the container 3.

[0114] For each of the two plates constituting the cover 6, two steel cables 11 are used for reciprocating movement, thus a total of four steel cables 11 are used to pull the cover to the top of the container 3. Furthermore, for each steel cable 11, two movable pulleys 12a are used, installed at positions on each plate of the cover 6 (on the frame) that are separated in the longitudinal direction of the cover 6 (that is, the direction perpendicular to the direction of movement). When the steel cable 11 is pulled, a force is applied to the two movable pulleys 12a at the separated positions, causing the cover 6 to move. Using the two movable pulleys 12a, the force in the direction of movement acts on each plate of the cover 6 at two points separated in the longitudinal direction. Therefore, the cover 6 can move correctly in parallel without tilting or getting stuck on the guide rail 14, thereby opening and closing the loading port 5. A limiter 18 that can adjust the top position is installed on the top of the container 3, thereby determining the range of movement of each plate of the cover 6.

[0115] Regarding each of the two plates in the cover 6, steel cables 11 and pulleys 12 and 12a are arranged in the opening and closing directions, so by operation Figure 2 Each rod 22 of the operating component 20 shown can arbitrarily open and close each plate of each cover 6.

[0116] For the two plates of the cover 6, a sealing mechanism 30 is provided to prevent rainwater from entering between the two (between the abutted top edge portions) when the loading port 5 is closed. Figure 5 This configuration is shown in the drawing. That is, between the top edge portions of the two plates which abut in the closed state of the loading port 5, a rubber elastic sealing material 31a is installed on one edge portion, and a metal member 31b which presses the end surface of the elastic sealing material 31a in the horizontal direction is provided on the edge portion of the other plate.

[0117] In Figure 5 the example, in order to reliably prevent the penetration of rainwater, in addition to the combination of the sealing material 31a and the metal member 31b, a tongue-shaped rubber sealing material 32b is installed on a portion of the metal member 31b which presses a metal sheet 32a extending in the horizontal direction from the plate on which the elastic sealing material 31a is installed. That is, a configuration in which a metal member presses an elastic sealing material horizontally is provided doubly.

[0118] In order to prevent the penetration of rainwater when the cover 6 is closed, between the rear end edge portion (the edge portion on the side opposite the abutted side) of one plate and the edge portion of the loading port 5, the same water seal configuration as the sealing mechanism 30 is provided. That is, as shown in the drawing, Figure 5 as shown in the lower drawing, an elastic sealing material 33a is installed inside the edge portion of the cover 6, and a metal member 33b is provided outside the edge portion of the loading port 5 so that the metal member presses the elastic sealing material in the horizontal direction when the cover 6 is closed.

[0119] With regard to the edge portions at both ends in the length direction of the loading port 5 and the side edge portions (edge portions in the direction of movement of the cover 6) of the cover 6, as shown in the drawing, Figure 4 of the cover 6 is covered by the side cover 15, a water penetration prevention sheet 35 is installed between the two edge portions.

[0120] In Figures 6 to 10 , another embodiment of the bulk cargo container 2 of the present application is shown. The bulk cargo container 2 also receives powder-particle cargo from the loading port 5 at the top and discharges it from the discharge port 8 at the bottom, like the bulk cargo container 1 shown in Figure 1 , etc. The configuration of the discharge port 8 and the hinged door type door 9 which opens and closes it is the same as that of the bulk cargo container 1. The size of the container 3 is also the same.

[0121] The loading port 5 located at the top is provided as a longitudinal opening along the length direction of the container 3, and a door type cover 6 is provided at the loading port 5. Also, since the cover 6 is provided in two pieces, the two pieces are butted at the center of the container 3 to cover the entire loading port 5, and are horizontally slid away from each other from the center in the width direction, so that the pieces are moved apart, and thus the opening of the loading port 5 is not different from the bulk cargo container 1.

[0122] However, in the bulk cargo container 2, a transmission mechanism including a steel cable and a pulley is not used as a method of moving the cover 6. Instead, an operation member 50 is directly connected to one end of each piece of the cover 6, which is disposed at one end wall surface of the container 3 as shown in Figure 7 , and a worker can move each piece of the cover 6 back and forth by operating the operation member 50 by hand.

[0123] In this case, as shown in Figure 6 , each piece of the cover 6, which covers the longitudinal loading port 5, is moved in the width direction by applying force to only one end (the left end side in Figure 6 ) and is supported by a linear bushing device 40 provided near both ends in the length direction. The linear bushing device 40 is a linear guide device including a linear guide member 41 and a moving block 42 mounted to the outside of the guide member 41 by a rotating body (not shown) such as a ball or a roller, as shown in Figure 8 , Figure 9 . When the guide member 41 is fixed toward the width direction of the container 3, each piece of the cover 6 mounted to the moving block 42 can be moved in the direction of opening and closing the loading port 5 along the guide member 41 with extremely low friction. Since the movement is smooth, the cover 6 is always moved smoothly in parallel even when the operation member 50 applies force to only one end.

[0124] As shown in Figure 8 , each piece of the cover 6 is connected to a support frame 6f extending in the length direction thereof, and the moving block 42 is mounted to the frame 6f. Also, the operation member 50 provided at one end wall surface of the container 3 is a member connected to the front end of the support frame 6f by welding or the like. A fixing member 51 is provided at the side of the container 3 where the operation member 50 is disposed, as shown in Figure 7 , so that the operation of the operation member 50 and the cover 6 can be locked.

[0125] At positions covering both ends in the length direction of the linear bushing device 40 and the cover 6, side covers 45 are provided, as shown in Figure 6 , for protecting the linear bushing device 40 and preventing rainwater from entering the container 3 from the ends of the cover 6.

[0126] Also, near both ends in the length direction on the top of the container 3, limiters 48 capable of adjusting the position of the top end are installed. When the cover 6 is moved, a portion of the support frame 6f touches the top end portion of those limiters 48, whereby the moving range of each plate of the cover 6 is determined.

[0127] Figure 9 The state in which both end portions in the length direction of the cover 6 are supported by the linear bushing device 40 is shown in FIG. 2. Two guide members 41 are installed in parallel at a distance of approximately 4.5 meters near both end portions in the length direction of the loading port 5.

[0128] When each plate of the cover 6 is completely fixed with respect to the moving block 42 on each guide member 41, in the case where the parallelism between the two guide members 41 is lowered, the movement of the cover 6 can not be smooth. Also, the two guide members 41 are spaced several meters apart, so the parallelism between them is likely to be lowered. However, in this bulk cargo container 2, it is necessary to move the cover 6 using the operation member 50 that is connected on only one side, so the movement needs to be particularly smooth.

[0129] Here, in this example, with respect to the moving block 42 installed on one of the two guide members 41 (the left one), the frame 6f of the cover 6 is fixed with a bolt 43, and, on the other hand, with respect to the moving block 42 installed on the other guide member 41 (the right one), the frame 6f of the cover 6 is installed in a floating manner. That is, the moving block 42 shown on the right in FIG. 4 is installed with a bolt-like connecting pin 44 above, and a gap of several millimeters or so is provided in the horizontal direction and the vertical direction between the support pin 44 and the frame 6f. Figure 9 Figure 9 Figure 9

[0130] In the bulk cargo container 2, as shown in FIG. 5, at a position approximately in the middle in the length direction, across the loading port 5, a support rail 46 is installed in the width direction, and wheels 6g that move mounted on the support rail 46 are installed on the lower portion of the cover 6. In consideration of the fact that the cover 6 has a length of approximately 4 meters, the weight of the approximately middle portion thereof is supported so as to prevent deformation. Figure 9

[0131] The support rail 46 uses a device in the shape of a central portion protruding upward so that the powder-like cargo that is poured does not adhere and accumulate. However, the wheels 6g provided on the cover 6 are generally in the shape of a cylinder. In the example shown in the drawing, the moving path of the cover 6 is correctly determined by the linear bushing device 40, and there is no risk of the wheels coming off, so such wheels 6g are adopted.

[0132] ​​​​In closing the loading port 5 with the two plates of the cover 6, to prevent rainwater from entering the container 3 through the gap between the top edge portions of the two plates, a special sealing mechanism 60 is provided. The two plates of the cover 6 are operated by the operating member 50 from only one side, so that the top edge portions of the two plates are difficult to be butted against each other without a gap with equal force over the entire length. In view of this, as shown in Figure 10 , the sealing mechanism 60 is configured to cover the top edge portions of the two plates from above with a water seal cover 61 so that an elastic sealing material 62 is brought into close contact therewith.

[0133] As shown in Figure 10 (roughly intermediate drawing), the water seal cover 61 is mounted to either one of the two plates of the cover 6 in a manner that it can swing in the vertical direction, and the elastic sealing material 62 is mounted to the lower surface thereof. On the other hand, two upward metal members 63 are mounted to each of the top edge portions of the two plates of the cover 6.

[0134] The water seal cover 61 is normally in a state of being displaced upward by the action of a spring (not shown), but when the operating lever 64 mounted to the other plate is operated to rotate the illustrated pressing member 65, the top end portion 61a is pressed by the pressing member 65, so that the water seal cover 61 swings downward. When it swings downward, as shown in the drawing, the elastic sealing material 62 of the water seal cover 61 is pressed against and brought into close contact with the upward metal member 63 of the cover 6, so that rainwater can be prevented from penetrating through the gap between the top edge portions of the two plates. The operating lever 64 is linked to the water seal operating member 66 as shown in Figure 7 , so that by lowering the same member 66 and then fixing (locking) it, the sealing state with the water seal cover 61 can be maintained.

[0135] To prevent the penetration of rainwater when the cover 6 is closed, as shown in Figure 10 (lower drawing), a water seal structure is also provided between the rear edge portion (the edge portion on the side opposite to the butting side) of one plate and the edge portion of the loading port 5. That is, an elastic sealing material 67 is mounted inside the rear edge portion of the plate of the cover 6, and a metal member 68 is provided outside the edge portion of the loading port 5, and the metal member 68 presses against the elastic sealing material 67 when the cover 6 is closed.

[0136] Further, as to the gap between the edge portions of the lengthwise direction of the loading port 5 and the side edge portions (edge portions in the direction of movement of the cover 6) of the cover 6, as shown in Figure 9 (left and right drawings), the gap is covered by the side cover 45, and a water penetration preventing sheet 69 is mounted between the edge portions.

[0137] In Figure 11(a) to (c) show examples in which the inclined plates 71 or the impellers 72 are provided immediately below the loading port 5 of the container 3. This is in consideration of a case where, when the powder or granular cargo A is thrown from the vicinity of the center line of the lengthwise loading port 5, the cargo A cannot be filled to the positions on the sides.

[0138] The inclined plates 71 or the impellers 72 are installed in one row in the lengthwise direction of the loading port 5, or are installed in two or three rows at appropriate intervals, and are adjusted in direction so that the cargo A thrown in the vicinity of the center is dispersed and falls to the sides (widthwise direction). Figure 11 (a) shows an example in which the inclined plates 71 are arranged in two rows so as to abut on the vicinity of the center of the loading port 5, Figure 11 (b) is an example in which the inclined plates 71 are arranged in two rows at intervals in the range of the opening of the loading port 5, Figure 11 (c) is an example in which the impellers 72 are also arranged in two rows at intervals. The arrangement of the inclined plates 71 or the impellers 72 is not limited to the examples shown in the drawings, but by appropriately using those, it is possible to cause the cargo A to not only fall in the vicinity of the center, but also to spread to the left and right sides, and as shown in the drawings, it is also possible to fill the cargo A to the portions on the sides in a large amount.

[0139] Figures 12 to 16 The bulk cargo container 4 of still another embodiment of the application is shown in FIG. 12. As with the bulk cargo containers 1 and 2 described above, the bulk cargo container 4 is used in such a manner that powder or granular cargo is received from the loading port 5 at the top to be stored or transported, and the like, and is then taken out from the discharge port 8 at the lower portion.

[0140] The bulk cargo container 4 has a structure similar to that of the bulk cargo container 2. For example, as shown in FIGS. 13(a) and 13(b), the loading port 5 at the top is taken as a lengthwise opening in the lengthwise direction of the container 3, and a door-type cover 6 is provided at the loading port 5. In addition, the cover 6 is constructed so that two plates are taken as one set, the two plates are butted against each other to cover the entire loading port 5 at the center portion of the container 3, and the two plates are moved horizontally away from each other in the widthwise direction from the center portion to open the loading port 5, and the like, and this structure is also the same as that of the bulk cargo container 2. Figure 12

[0141] In addition to this, in order that each plate of the cover 6 can be smoothly moved with extremely low friction, the points at which the each plate is supported by the linear bushing devices 40 provided in the vicinity of both end portions in the lengthwise direction are also the same as those of the bulk cargo container 2. As shown in FIG. 14(a), Figure 14 Figure 15 ​​As shown, the linear bushing device 40 is a linear guide device including a linear guide member 41 having a length in the width direction of the container 3 and a moving block 42 mounted on the outer side of the guide member 41 by a rolling element (omitted from the drawing), and is the same as that used in the bulk cargo container 2. A side cover 45 for preventing rainwater from penetrating is provided at positions on both sides of the length direction end portions of the linear bushing device 40 and the cover 6, and is not different from the bulk cargo container 2.

[0142] Note that, since many of the parts are common to the bulk cargo container 2 in structure, regarding the bulk cargo container 4, the same reference numerals are given to the same structural parts as those of the bulk cargo container 2 (hereinafter, the repeated explanation about the same parts is omitted or simplified). Figures 12 to 16

[0143] As shown in FIG. 4, unlike the bulk cargo container 2, an operation member 80 as a member for operating each plate of the cover 6 is provided on the top, i.e., the ceiling portion, of the bulk cargo container 4, instead of the side portion of the container 3. Specifically, the operation member 80 is provided at a position near the wall surface (one side wall surface in FIG. 4) of the end portion having the discharge port 8 and the door 9 in the ceiling portion. Figure 14 The operation member 80 is a member for moving each plate of the cover 6 in the width direction of the container 3 (i.e., the direction of opening and closing the loading port 5) by a worker holding it by hand, and is installed to the support frame 6f of each plate of the cover 6. Figure 13 When the operation member 80 is moved in the width direction of the container 3, the operation is transmitted to each plate of the cover 6 through the support frame 6f, so that the cover 6 can be moved to open and close the loading port 5. The operation member 80 is located only near the end portion of one side in the length direction of the container 3, but each plate of the cover 6 is supported by the linear bushing device 40 and moved with extremely low friction as described above, so that the entire each plate can be smoothly moved in parallel.

[0144] Figure 14 In the ceiling portion of the container 3, a fixing member 81 is provided at a position near the operation member 80, and can lock the operation of the cover 6 in the fully open state and the closed state of the loading port 5.

[0145] In addition, as in the case of the bulk cargo container 2, as shown in FIG. 4, a limiter 48 for determining the moving range of each plate of the cover 6 is installed near both ends in the length direction of the top of the container 3 in the bulk cargo container 4.

[0146] Figure 14

[0147] Figure 15 ​​​​The support state of the cover 6 of the roof portion of the container 3 is shown. The respective plates of the cover 6 are supported at both end portions in the longitudinal direction by the linear bushing device 40 as described above. Although detailed illustration is omitted, the linking state of the cover 6 to the moving block 42 of the linear bushing device 40 is the same as in the case of the bulk cargo container 2. That is, the frame 6f of the cover 6 is fixed to the moving block 42 mounted to one of the two guide members 41 (for example, the left side in Figure 15 ), and on the other hand, the frame 6f is mounted to the moving block 42 mounted to the other guide member 41 in a manner that it can float by several millimeters or so in the horizontal direction and the vertical direction (refer to the description related to the bulk cargo container 2 in Figure 9 ), so that the cover 6 can always move smoothly.

[0148] Further, support rails 46 are provided in the width direction across the two places of the loading port 5 in the vicinity of the center in the longitudinal direction, and wheels 6g that move on the support rails 46 are mounted to the lower portion of the cover 6. A member that protrudes upward in the central portion is used as the support rail 46, so that powdery cargo does not adhere and accumulate.

[0149] Figure 16 (a) ~ Figure 16 A sealing mechanism 60 for preventing rainwater from penetrating when the loading port 5 is closed by the cover 6 is shown in (c). The sealing mechanism 60 is configured to be substantially the same as the sealing mechanism provided to the bulk cargo container 2 (refer to Figure 10 ). That is, to the top end edge portions of the two plates of the cover 6 in the state where the loading port 5 is closed, a water seal cover 61 is provided so that an elastic sealing material 62 on the lower surface thereof seals, so that rainwater can be prevented from penetrating between the top end edge portions of the two plates where a gap is likely to occur.

[0150] As shown in (b) and (c), the water seal cover 61 is mounted to either one of the two plates of the cover 6 in a manner that it can swing in the vertical direction, and an elastic sealing material 62 is attached to the lower surface thereof. On the other hand, an upward metal member 63 is provided to each of the top end edge portions of the two plates of the cover 6. Further, a rotating pressing member 65 is provided to the other plate that faces the plate on which the water seal cover 61 is mounted. When the pressing member 65 is rotated as in (b), the water seal cover 61 swings downward and rotates because the top end portion 61a is pressed, so that the elastic sealing material 62 is pressed against the upward metal member 63 of the cover 6 and seals as shown in the figure. In this state, a water seal effect can be exerted. Figure 16 Figure 16 Figure 16 When the pressing member 65 is rotated as in (b), the water seal cover 61 swings downward and rotates because the top end portion 61a is pressed, so that the elastic sealing material 62 is pressed against the upward metal member 63 of the cover 6 and seals as shown in the figure. In this state, a water seal effect can be exerted.

[0151] The sealing mechanism 60 employed by the bulk cargo container 4 is the same as the sealing mechanism of the bulk cargo container 2 (refer to Figure 16 ). Figure 10 ​​The following improvements were made.

[0152] First, such as Figure 16 As shown in (b) and (c), the metal components 63 formed on the two plates of the cover body 6 are arranged in a row at the top edge of each plate, and a soft rubber cover 63a that is easily elastically deformable is installed at the upper end of each metal component 63. In addition, the front and rear (left and right in the figure) edges of the water seal cover 61 extend downward to each plate of the cover body 6, and a soft rubber cover 61b that is easily elastically deformable is also installed at its lower end. Not only the elastic sealing material 62, but also the cover 61b and 63a can improve the water seal effect, so rainwater can be reliably prevented from seeping into the container 3.

[0153] In addition, the water seal operating lever 68, which serves as a component for operating the pressing member 65, is as follows: Figure 14 The water seal cover 61 is shown to be installed on the top of the container 3. The operating lever 68 rotates the pressing member 65, thereby locking the water seal cover 61 in a pressed state and maintaining the water seal. The water seal operating lever 68 is positioned next to the operating member 80 that moves the cover 6, as shown in the figure. This allows for quick and easy operation of moving the cover near the same end to open and close the loading port 5, and also prevents rainwater from seeping in when the loading port 5 is closed.

[0154] The bulk cargo container 4 also takes into full consideration the issue of preventing rainwater from seeping in through the loading port 5 when the cover 6 is closed. That is, except for the aforementioned sealing mechanism 60, it adopts the same structure as the bulk cargo container 2. For example, a sealing mechanism is provided between the rear edge of each panel of the cover 6 (the edge opposite to the mating side) and the edge of the loading port 5. Figure 10 The bottommost diagram shows the structure (including the elastic sealing material 67). Furthermore, the gap between the two ends of the filling port 5 along its length and the side edges of the cover 6 (edges along the moving direction of the cover 6) is also designed using… Figure 9 The left and right lead-out diagrams show the structure (including the waterproof sheet 69).

[0155] Figure 17 The figure illustrates a structure that improves the packing state of granular cargo within a container 3 according to the present invention. When granular materials are fed only from near the center of the longitudinally elongated loading port 5, the granular materials accumulate in a conical shape, resulting in large spaces at the front and rear of the container 3 where no granular materials may be present. The figure shows an example of the aforementioned bulk cargo container 4, but this structure can be used in any bulk cargo container that feeds granular cargo.

[0156] exist Figure 17 In the example, as a means of improving the stacking condition, two points are suspended on the upper part of the inner side of container 3.Figure 17 (a) Figure 17 (b) shows a swingable partition 90. Figure 17 As shown in (b), the partition 90 is a flat plate extending in the width direction of the container 3 below the support shaft 91 located at the upper end, and having a surface intersecting the length direction of the same container 3. The support shaft 91 is supported by a bearing 92 located on the outer side of the loading port 5 in the width direction in the canopy section, allowing it to swing.

[0157] like Figure 17 As shown in (c), two protrusions 93 are provided at 90° intervals on the side surface of the support shaft 91, and additionally as... Figure 17 As shown in (d), limiters 94 are installed at the corresponding positions of each protrusion 93. Due to the action of these protrusions 93 and limiters 94, each of the two partitions 90 can... Figure 17 (a) shows the swing displacement within a range of 90°. That is, it swings between the lower part of the partition 90 facing the vertical direction and the side facing away from the center of the container 3.

[0158] When the partition 90 is installed on the top of the container 3 as described above, by slightly moving the vehicle carrying the container 3 forward and backward and then stopping it suddenly, a portion of the powdery cargo concentrated near the center of the container 3 can be smoothly moved to the front and rear portions of the container 3. Due to the effect of the two partitions 90, which can only swing and displace to the side away from the center, the powdery cargo can only move from the center to the front and rear ends based on the inertia generated when the vehicle stops suddenly. When the uneven stacking state of the powdery cargo can be improved in this way, more powdery cargo can be added into the container 3, thereby increasing the cargo capacity of the bulk container 4.

Claims

1. A bulk cargo container for receiving powdery or granular goods fed into the container through a loading port located at the top, characterized in that, The loading port is covered by a sliding door-type cover that opens and closes by horizontally reciprocating movement. The cover is linked to the operating components located on the container to perform the reciprocating movement. The operating component is positioned above the discharge port for discharging the cargo on the side of the container or near the side of the container's roof where the discharge port is located. The cover is composed of a single plate capable of covering the entire filling port, or of two plates that cover the entire filling port by bringing their opposing edges close together and joining them. When the filling port is closed using the cover, the top edge of the cover is aligned with the opening edge of the filling port, or the top edges of the two opposing plates of the cover are aligned. An upward-facing metal component is disposed at the edge of both, and a water seal cap with an elastic sealing material on its lower surface is installed near one of the edges. By moving the water seal cap using an operating component disposed on the side of the container, the elastic sealing material can be pressed from above onto the upward-facing metal component at the edge of both.

2. The bulk cargo container according to claim 1, characterized in that, The loading port has an elongated rectangular opening along the length of the container, and the cover moves horizontally back and forth along the width of the container to open and close the loading port.

3. The bulk cargo container according to claim 1, characterized in that, The operating components are only located on one side wall surface of the container. Straight guide members are arranged parallel to each other near both ends along the length of the feeding port, and each guide member is mounted on a moving block of a built-in rotating body that moves along the straight line. The cover is movable by being mounted on the movable block, and is linked to the operating member by a part of the cover, and the cover and the operating member perform the reciprocating movement in linkage.

4. The bulk cargo container according to claim 3, characterized in that, The cover is mounted such that it is fixed relative to a movable block mounted on one of the guide members located near both ends of the loading port, and is free to move relative to a movable block mounted on the other guide member.
