Description

Technical Field

[0001] This invention relates to the field of container technology, and more specifically to a container for transporting bulk cargo. Background Technology

[0002] Bulk cargo containers are being used more and more widely as containers for storing and transporting bulk cargo.

[0003] Existing bulk cargo containers typically have a discharge hopper at the end of the container. During unloading, the container needs to be tilted at a certain angle so that the bulk material can move to the discharge hopper due to gravity and be discharged through the hopper. This type of bulk cargo container requires a special device to tilt the container during unloading, which is inconvenient and costly due to the limitations of the special device.

[0004] Some bulk cargo containers have a discharge hopper at the smaller end of the container. During unloading, an operator needs to enter the smaller end of the container to open the discharge hopper and install the discharge pipe. This type of bulk cargo container requires a lifting device to lift the container, thus creating the operating space at the smaller end of the discharge hopper. Due to the limitations of the lifting device, it is inconvenient to use, cumbersome to operate, and costly.

[0005] Therefore, a container is needed to at least partially solve the problems existing in the prior art. Summary of the Invention

[0006] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] To at least partially address the aforementioned problems, according to one aspect of the present invention, a container is provided for transporting bulk cargo, comprising:

[0015] Optionally, the small ends of adjacent discharge hoppers are located on both sides of the first central plane and are equidistant from the first central plane, and / or the at least two discharge hoppers are symmetrical with respect to the second central plane in the length direction.

[0016] Optionally, the discharge hopper has a first wall extending between the small end and the side wall closer to the small end, and the discharge port is disposed at the small end of the first wall.

[0017] Optionally, the outer surface of the first wall faces the side of the sidewall that is closer to the small end, and / or

[0018] The first wall has a minimum dimension that extends downwards at an angle.

[0019] Optionally, the discharge hopper is formed by connecting at least four triangular walls in succession, with adjacent walls forming an angle or having an arc transition at the connection point.

[0020] Optionally, the discharge hopper is formed by four triangular walls connected in succession, with the top edge of the first wall and the top edge of the second wall respectively connected to the corresponding side wall, and the top edges of the third wall and the fourth wall respectively connected to the corresponding end wall or the third wall of the adjacent discharge hopper.

[0021] Optionally, the discharge port faces the side of the sidewall that is closer to the center of the discharge port, or

[0055] First Implementation Method

[0056] like Figures 1 to 4 As shown, the present invention provides a container 100 for transporting bulk cargo, particularly dry bulk cargo. In other words, the container 100 provided by the present invention is a bulk cargo container.

[0057] Typically, a container 100 includes a container body 110 and a base frame 102 disposed below the container body 110. The base frame 102 is connected to the container body 110 via corner posts 101 at the four corners of the container 100. Alternatively, vertically extending reinforcing beams 103 may be provided to connect the base frame 102 to the container body 110. Further, the container body 110 includes opposing side walls 111 and opposing end walls 112, which are successively connected to form a rectangular container wall. The base frame 102 is located below the side walls 111, and is spaced apart from the side walls 111 to form an open space.

[0058] To facilitate unloading, the housing 110 also includes a discharge hopper 120 located at the lower part of the housing 110. The discharge hopper 120 has a large end 126 and a small end 127 located below the large end 126. The large end 126 of the discharge hopper 120 is connected to the housing wall, and a discharge port 121 can be provided at the small end 127 of the discharge hopper 120 for unloading.

[0059] The larger end 126 of the discharge hopper 120 can be connected to the side wall 111 and / or the end wall 112. The discharge hopper 120, together with the side wall 111 and the end wall 112, forms a box 110 with an internal space for filling bulk goods. The smaller end 127 of the discharge hopper 120 is provided with a discharge port 121 for unloading. Optionally, the box 110 may include at least two discharge hoppers 120, each of which has a discharge port 121 at its smaller end 127. Figure 7 At least two discharge hoppers 120 can be arranged along the length direction D2 of the container 100. The larger end 126 of the discharge hopper 120 near the end wall 112 can be connected to the end wall 112, and the larger ends 126 of adjacent discharge hoppers 120 can be connected together. A sealing cover 131 can be provided at the discharge port 121 to ensure the airtightness of the container body 110. The sealing cover 131 can be opened and closed at the discharge port 121 to facilitate unloading after the sealing cover 131 is opened.

[0060] Optionally, the discharge hopper 120 can be positioned above the base frame 102. The smaller end 127 of the discharge hopper 120 may not protrude beyond the base frame 102. The operator can operate the sealing cover 131 using the open space between the base frame 102 and the side wall 111. A support member (not shown) may be provided between the discharge hopper 120 and the base frame 102 to support the discharge hopper 120 upwards. The support member may be distributed along the length direction D2 and the width direction D1.

[0061] In this embodiment, the discharge hopper 120 tapers from top to bottom. The discharge hopper 120 is constructed with an eccentric structure. That is, the discharge hopper 120 is an eccentric funnel. The centerline of the discharge hopper 120 is inclined in the height direction D3 of the container 100. In other words, the centerline of the discharge hopper 120 does not extend along the height direction D3. The centerline is a geometric centerline. In the illustrated embodiment, the centerline of the discharge hopper 120 can be approximately defined as follows:

[0062] like Figure 5 As shown, the discharge hopper 120 may define a top plane region R1 in the horizontal direction at its large end 126 and a bottom plane region R2 in the horizontal direction at its small end 127. The bottom plane center C2 of the bottom plane region R2 may be offset from the top plane center C1 of the top plane region R1 by a distance L1 in the horizontal direction. That is, the bottom plane center C2 and the top plane center C1 are not collinear in the height direction D3 of the container 100. The centerline is a line that extends through the top plane center C1 and the bottom plane center C2.

[0063] Figure 5The top plane region R1 and the bottom plane region R2, arbitrarily selected at a certain height, are schematically marked with dashed lines. The approximate horizontal positions of the top plane center C1 and the bottom plane center C2 are also schematically shown. The shapes of the top plane region R1 and the bottom plane region R2 are defined by the walls surrounding the discharge hopper 120. In the illustrated embodiment, each of the top plane region R1 and the bottom plane region R2 is polygonal. The area of ​​the top plane region R1 is larger than the area of ​​the bottom plane region R2.

[0064] It is understood that in this text, the large end 126 and the small end 127 are relative, and both have finite dimensions in the height direction D3. It should be noted that the tops of the various walls of the discharge hopper 120 can be approximately at the same horizontal plane. The bottom of each wall will form a structure with a bottom surface, or converge into a point or a ridge. For the embodiment where the bottoms of the various walls converge into a point or a ridge, "at the small end 127 of the discharge hopper 120" refers to the portion of the discharge hopper 120 located above that point or ridge.

[0065] like Figure 7 and Figure 8 As shown, the center of the discharge port 121 is spaced apart from the first center plane P1 of the container 100 in the width direction D1 by a predetermined distance L2. This predetermined distance L2 needs to ensure that when the operator opens the sealing cover 131 from one side of the side wall 111, the operator can directly touch the sealing cover 131 with his / her hand without having to go under the container 110.

[0066] The discharge port 121 can face the side of the sidewall 111 that is closer to the center of the discharge port 121. Of course, in embodiments not shown, the discharge port 121 can be located at the bottom of the small end, and the direction of the discharge port 121 can be downward. Specifically, the sidewall 111 defines a sidewall extension surface in the height direction D3, and the center position of the discharge port 121 can be set such that the distance between the sealing cap 131 and the sidewall extension surface of the sidewall 111 closer to the discharge port 121 is approximately less than or equal to the length of the operator's arm. For example, in the illustrated embodiment, for the first discharge hopper 120a, the discharge port 121 on the first discharge hopper 120a is closer to the first sidewall 111a relative to the second sidewall 111b. The center position of the discharge port 121 can be set such that the distance between the sealing cap 131 and the sidewall extension surface of the first sidewall 111a is approximately less than or equal to the length of the operator's arm.

[0067] Furthermore, the small end 127 of the discharge hopper 120 can be spaced apart from the first center plane P1, so that the discharge port 121 provided at the small end 127 can be closer to the side wall extension surface of the corresponding side wall 111. The discharge hopper 120 can be arranged as needed. For example, the discharge hopper 120 can be arranged such that there is at least one small end 127 on each side of the first center plane P1, and at least one small end 127 on each side of the second center plane P2 in the length direction D2.

[0068] To maintain the balance and stability of the container 100 (specifically, the stability of its overall center of gravity), as illustrated in the embodiment, a configuration is shown where 2N hoppers 120 are included. These 2N hoppers 120 can be arranged such that N have small ends 127 located on either side of the first central plane P1, thereby achieving overall weight balance of the container 100 in the width direction D1. Furthermore, the 2N hoppers 120 can also be arranged such that N have small ends 127 located on either side of the second central plane P2, thereby achieving overall weight balance of the container 100 in the length direction D2.

[0069] Optionally, adjacent discharge hoppers 120 are installed in opposite directions in the width direction, allowing them to be arranged in a staggered manner. For example, the first discharge hopper 120a is arranged with its discharge port 121 facing the side containing the first sidewall 111a, and the second discharge hopper 120b is arranged with its discharge port 121 facing the side containing the second sidewall 111b. Specifically, as... Figure 7 As shown, this staggered arrangement can be further defined as follows: the small ends 127 of adjacent discharge hoppers 120 can be located on both sides of the first center plane P1. Optionally, the distance from the bottom plane center C2 of adjacent discharge hoppers 120 to the first center plane P1 can be approximately equal, so as to keep the center of gravity of the container 100 on or near the first center plane P1 in the width direction D1.

[0070] The discharge hoppers 120 are generally similar in structure and / or shape to each other. At least two discharge hoppers 120 may be symmetrical with respect to the second center plane P2 in the length direction D2, thereby keeping the center of gravity of the container 100 on or near the second center plane P2 in the length direction D2. For the illustrated embodiment, 2N discharge hoppers 120 may be symmetrical with respect to the second center plane P2 in the length direction D2.

[0071] The volumes of the hoppers 120 can all be approximately the same, thereby maintaining the balance and stability of the container 100, specifically the stability of its overall center of gravity. For example, in the illustrated embodiment, the container 110 includes four hoppers 120, and the volumes of the four hoppers 120 can be approximately the same.

[0072] Furthermore, the discharge hopper 120 can be formed by walls of different sizes and / or shapes. The top edges of the walls of adjacent discharge hoppers 120 are connected, and the top edge can extend between two side walls 111, and the angle between the top edge and the first center plane P1 is an acute angle.

[0073] like Figure 5 As shown, the discharge hopper 120 has a first wall 122 extending between a small end 127 and a side wall 111 closer to the small end 127. In the illustrated embodiment, the side wall 111 closer to the small end 127 is the same side wall 111 closer to the discharge port 121, and also closer to the center C2 of the bottom plane. For example, for the first discharge hopper 120a, the first side wall 111a is closer to the small end 127 of the discharge hopper 120, closer to the discharge port 121, and closer to the center C2 of the bottom plane than the second side wall 111b.

[0074] The first wall 122 extends downwards at an angle and may have a minimum downwardly extending dimension L3. Figure 5 In other words, the first wall 122 has the shortest extension distance from its top to its bottom; specifically, the extension distance of the first wall 122 is shorter than the extension distance of the other walls from their top to their bottom. The discharge port 121 can be provided on the first wall 122, specifically at the lowest part of the first wall 122. This allows the discharge port 121 to be closer to the sidewall extension surface of the corresponding sidewall 111. The outer surface of the first wall 122 can face the side of the sidewall 111 closer to the small end 127, so that the discharge port 121 can face the side of the sidewall 111 closer to the small end 127, allowing the operator to directly observe the unloading situation at the discharge port 121.

[0075] like Figure 5 and Figure 6 As shown in the illustrated embodiment, the discharge hopper 120 is depicted as a square pyramid shape. The discharge hopper 120 is formed by the successive connection of at least four triangular walls, with adjacent walls forming an angle or having an arcuate transition at the connection point. The walls can be constructed from triangular plates. In one embodiment, two adjacent walls can be directly welded together, resulting in a polygonal horizontal planar area of ​​the discharge hopper 120. In another embodiment, two adjacent walls can be connected by an arcuate plate, such as a circular arc, so that the small end 127 of the discharge hopper 120 can have a circular horizontal planar area.

[0076] The discharge hopper 120 is formed by the sequential connection of four partially triangular walls. The top edge of the first wall 122 and the top edge of the second wall 123 are respectively connected to the corresponding side walls 111. The top edges of the third wall 124 and the fourth wall 125 are respectively connected to the corresponding end walls 112 or the third wall 124 of an adjacent discharge hopper 120. For example, in the illustrated embodiment, for the first discharge hopper 120a, the top edge of the first wall 122 is connected to the first side wall 111a, the top edge of the second wall 123 is connected to the second side wall 111b and the corresponding end wall 112, the top edge of the third wall 124 is connected to the corresponding end wall 112, and the top edge of the fourth wall 125 is connected to the top edge of the third wall 124 of the middle discharge hopper 120. The apex of the fourth wall 125 is connected to the two side walls 111 respectively. Of course, the wall configuration of the discharge hopper 120 is not limited and can be combined arbitrarily as needed, but it is necessary to ensure that no material is stored inside the box 110 when unloading.

[0077] Optionally, return to reference Figure 3 The container body 110 includes a top cover 113 located above the side walls 111 and end walls 112. The top cover 113 covers a top opening formed by the end walls 112 and the side walls 111. A feeding device 132 is provided on the top cover 113 to facilitate the filling of bulk goods after the feeding device 132 is opened. In the illustrated embodiment, the feeding devices 132 are spaced apart in the length direction D2, and the center of the feeding devices 132 is located on a first central plane P1. Alternatively, the container body 110 may only have a top opening without a top cover 113; in other words, the container 100 may be an open-top container with a top opening.

[0078] Second Implementation Method

[0079] The following is for reference Figure 9 The container 200 of the second embodiment will now be described. Except for the number of discharge hoppers 220, the container 200 has the same structure and / or construction as the container 100. Therefore, the components of the container 200 that are substantially the same as those in the first embodiment will be numbered in the same way here, and for the sake of brevity, they will not be described in detail and / or illustrated.

[0080] like Figure 7As shown, there are 2N+1 discharge hoppers 220. These 2N+1 discharge hoppers 220 can be arranged such that N and N+1 small-endpoints 227 are located on either side of the first center plane P1, respectively. This allows for overall weight balance of the container 100 in the width direction D1. Furthermore, the 2N+1 discharge hoppers 220 can also be arranged such that N small-endpoints 227 are located on either side of the second center plane P2. In this case, the small-endpoint 227 of the middle discharge hopper 220 is located on the second center plane P2. This allows for overall weight balance of the container 100 in the length direction D2.

[0081] The 2N+1 discharge hoppers 220 can be symmetrical with respect to the second center plane P2 in the length direction D2. Specifically, the middle discharge hopper 220 can be symmetrical with respect to the second center plane P2 in the length direction D2. The remaining discharge hoppers 220 are symmetrical with respect to the second center plane P2 in the length direction D2. The volume of the middle discharge hopper 220 can be greater than or equal to the volume of any of the remaining discharge hoppers 220. In the illustrated embodiment, the housing 210 includes three discharge hoppers 220, and the volume of the middle discharge hopper 220 can be greater than the volume of the discharge hopper 220 near the end wall 112.

[0082] In summary, the container provided by this invention allows the discharge port to be located at the smaller end of the eccentrically structured discharge hopper, and the discharge port can be positioned closer to the side wall. This allows the operator to quickly and manually open the sealing cover at the discharge port from one side of the side wall. After the sealing cover is opened, the bulk cargo inside the container can be automatically discharged by gravity, leaving no material behind. The operator does not need to enter the lower part of the container, nor does it require any other equipment to complete the unloading. After unloading, the operator can quickly and manually close the sealing cover from one side of the side wall to prevent contaminants from entering the container.

[0083] The container unloading operation provided by this invention is simple and quick, does not require any large auxiliary devices, has strong applicability and stability, a high safety factor, and leaves no residue after unloading.
