Description

Technical Field

[0001] This application relates to the field of containers, and more specifically to containers and unloading devices. Background Technology

[0002] General purpose bulk containers (GPCs) are used to transport bulk cargo (such as soybeans, grains, pulverized coal, mineral concentrate, or construction waste). GPCs have a top opening for loading bulk cargo. To unload the cargo, the container is tilted by raising its rear end. This allows the cargo to be discharged under gravity from the unloading port located below the front of the container.

[0003] For bulk cargo such as construction waste, which often contains long pieces of wood, steel bars, and cement blocks larger than the unloading opening, using the aforementioned general bulk cargo containers to transport construction waste may result in these long pieces of wood, steel bars, and cement blocks clogging the unloading opening and preventing the construction waste from being unloaded completely.

[0004] Therefore, this application provides a container and unloading device to at least partially solve the above-mentioned problems. Summary of the Invention

[0005] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed embodiments section. This summary section is not intended to limit the key features and essential technical features of the claimed technical solutions, nor is it intended to determine the scope of protection of the claimed technical solutions.

[0006] To at least partially solve the above-mentioned technical problems, this application provides a container, the container comprising:

[0007] The box has a bottom opening at the bottom and a bottom corner piece at the bottom. The bottom surface of the bottom corner piece has an elongated hole.

[0008] The bottom plate is detachably connected to the lower end of the housing between the open position of the bottom opening and the closed position of the bottom opening;

[0009] The twist lock assembly includes a first lock body and an upper lock head rotatably connected to the first lock body between a locked position and an unlocked position. The first lock body is connected to a base plate. When the plane of the base plate is perpendicular to the height direction of the housing, the upper lock head in the unlocked position can enter the bottom corner piece through the corner piece elongated hole and rotate within the bottom corner piece to a locked position that is offset from the long axis of the corner piece elongated hole, so as to lock the base plate in the closed position to the housing.

[0010] According to the container of this application, the twist lock assembly is used to lock the bottom plate in the closed position to the lower end of the container body. When it is necessary to unload the bulk cargo inside the container, the upper lock head can be rotated to the unlocked position so that the bottom plate can leave the container body and move to the open position, thereby unloading the bulk cargo inside the container. Due to the large bottom opening size, construction waste including long wooden blocks, steel bars and cement blocks can be unloaded cleanly.

[0011] Optionally, the enclosure has corner posts, and the outer surface of the corner posts is provided with enclosure brackets protruding from the outer surface.

[0012] Optionally, the outer facade of the enclosure is provided with a first guide portion protruding to the outer side of the outer facade, the first guide portion extending along the height direction of the enclosure.

[0022] When the container is moved to the first unloading position and the tilting support is in a flat position, the turnlock head is connected to the twist lock assembly to drive the upper lock head to rotate.

[0023] According to the unloading device of this application, the unloading device is used for the aforementioned container. The twist lock assembly is used to lock the bottom plate, which is in the closed position, to the lower end of the container. In this way, when it is necessary to unload the bulk cargo inside the container, the upper lock head can be rotated to the unlocked position so that the bottom plate can leave the container and move to the open position, thereby unloading the bulk cargo inside the container. Since the bottom opening size is large, construction waste including long wooden blocks, steel bars and cement blocks can be unloaded cleanly.

[0065] In the following description, numerous specific details are set forth to provide a more thorough understanding of this application. However, it will be apparent to those skilled in the art that embodiments of this application may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with embodiments of this application.

[0066] The preferred embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0067] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not have any other meaning, such as a specific order.

[0068] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, other embodiments may be available in addition to these detailed descriptions.

[0069] This application provides a container. The container can be used to transport bulk cargo such as soybeans, grains, pulverized coal, or concentrate. The container can be a top-opening container. The container's bottom plate 120 is removable. Thus, when it is necessary to unload the bulk cargo stored inside the container, the bottom plate 120 can be removed, allowing the bulk cargo to be unloaded from the container body 110 under its own weight.

[0070] like Figures 1 to 16 As shown, the container includes a body 110 and a floor 120. The body 110 includes vertical walls 119. The vertical walls 119 include side walls and end walls. The side walls and end walls form a generally cuboid structure. The upper end of the body 110 has a top opening through which bulk cargo can be loaded into the body 110. The lower end of the body 110 has a bottom opening 111.

[0071] Please refer to Figure 1 , Figure 2 and Figure 7The corner of the housing 110 has corner posts 114. A top corner piece 118 is provided at the top corner of the housing 110. A bottom corner piece 112 is provided at the bottom corner of the housing 110. The top corner piece 118 and the bottom corner piece 112 can be existing corner pieces. An elongated corner piece hole 113 is provided on the lower surface of the bottom corner piece 112 away from the top corner piece 118.

[0072] like Figures 1 to 6 As shown, the bottom plate 120 is detachably connected to the lower end of the container 110 between the open and closed positions. When the bottom plate 120 is in the closed position, it closes the bottom opening 111. At this time, the plane containing the bottom plate 120 is perpendicular to the height direction of the container 110. Thus, the bottom plate 120 serves to support loose goods located inside the container 110. When the bottom plate 120 is in the open position, it moves away from the lower end of the container 110 to open the bottom opening 111. At this time, the loose goods inside the container 110 can be unloaded from the container 110 through the bottom opening 111 under their own weight.

[0073] Please refer to Figures 3 to 6 The container also includes a twist lock assembly 130. The twist lock assembly 130 includes a first lock body 131 and a locking head 132. The locking head 132 is rotatably connected to the first lock body 131. Thus, the locking head 132 is rotatable between a locked position and an unlocked position. The first lock body 131 is connected to a corner of the bottom plate 120.

[0074] With the plane of the base plate 120 perpendicular to the height direction of the housing 110, the locking head 132 can be rotated to the unlocked position. In this case, the length direction of the locking head 132 is parallel to the long axis of the corner fitting's elongated hole 113. Moving the base plate 120 upwards to the closed position allows the locking head 132 to enter the bottom corner fitting 112 through the corner fitting's elongated hole 113. Rotating the locking head 132 within the bottom corner fitting 112 to the locked position then displaces the length direction of the locking head 132 from the long axis of the corner fitting's elongated hole 113. This allows the twist lock assembly 130 to lock the base plate 120, which is in the closed position, to the housing 110.

[0075] In this embodiment, the twist lock assembly 130 is used to lock the bottom plate 120, which is in the closed position, to the lower end of the box 110. When it is necessary to unload the bulk materials inside the box 110, the upper lock head 132 can be rotated to the unlocked position so that the bottom plate 120 can leave the box 110 and move to the open position, thereby unloading the bulk materials inside the box 110. Since the bottom opening 111 is large, construction waste including long wooden blocks, steel bars and cement blocks can be unloaded cleanly.

[0076] Preferably, the twist lock assembly 130 further includes a lower locking head 133 and a rotating shaft 134. The rotating shaft 134 is rotatably disposed through the first lock body 131. One end of the rotating shaft 134 is connected to the lower locking head 133. The other end of the rotating shaft 134 is connected to the upper locking head 132. Thus, the upper locking head 132 and the lower locking head 133 are located on opposite sides of the second lock body 161. Therefore, the upper locking head 132 can be rotated by operating the lower locking head 133.

[0077] More preferably, such as Figures 4 to 6 As shown, the length direction of the upper locking head 132 is perpendicular to the length direction of the lower locking head 133. Therefore, rotating the lower locking head 133 by approximately 90° allows the upper locking head 132 to rotate between the locked and unlocked positions, facilitating operation.

[0078] The cross-section of the upper locking head 132 (perpendicular to its length) is trapezoidal. The larger end of the trapezoidal structure of the upper locking head 132 is connected to the rotating shaft 134. Therefore, the trapezoidal cross-section of the upper locking head 132 guides its movement through the elongated hole 113 into the bottom corner piece 112, facilitating its entry into the bottom corner piece 112.

[0079] The cross-section of the lower lock head 133 (perpendicular to its length) is trapezoidal. The larger end of the trapezoidal structure of the lower lock head 133 is connected to the rotating shaft 134. The trapezoidal cross-section of the lower lock head 133 serves as a guide for its movement through the elongated hole 152 in the base plate, facilitating its operation.

[0080] Please refer to Figure 2 The outer surface of the corner post 114 is provided with a box bracket 115 protruding from the outer surface of the corner post 114. Along the width direction of the box 110, the box bracket 115 is located on the side of the corner post 114. Thus, the box bracket 115 can be used to support the box 110.

[0081] like Figure 9 and Figure 11 As shown, the outer facade of the vertical wall 119 is provided with a first guide portion 116 protruding to the outer side of the facade. The first guide portion 116 extends along the height direction of the housing 110. The facade includes the outer side surface of the side wall and the outer end surface of the end wall. Along the length direction of the housing 110, the first guide portion 116 is located outside the outer end surface and connected to the outer end surface. Thus, the first guide portion 116 can cooperate with the second guide portion 143 (described later) to guide the movement of the housing 110 within the unloading channel 141 (described later) along the height direction of the unloading rack 140 (described later).

[0082] It is understood that, in embodiments not shown, the first guide portion is located on the outer side of the sidewall and connected to the outer side along the width direction of the housing.

[0083] More preferably, the first guide portion 116 has a guide groove 117. As a result, the first guide portion 116 has high strength.

[0084] Preferably, such as Figure 6 and Figure 10 As shown, the upper surface of the bottom corner piece 112 is located above the lower surface of the vertical wall 119. The upper surface of the bottom corner piece 112 and the lower surface of the vertical wall 119 are spaced apart. The lower surface of the top corner piece 118 is located below the upper surface of the vertical wall 119. The interval between the upper surface of the top corner piece 118 and the upper surface of the vertical wall 119 is 1mm to 3mm. The interval between the lower surface of the bottom corner piece 112 and the lower surface of the vertical wall 119 is 1mm to 3mm. The lower surface of the top corner piece 118 and the upper surface of the vertical wall 119 are spaced apart. Furthermore, along the width direction of the container body 110, neither the top corner piece 118 nor the bottom corner piece 112 protrudes from the outer surface of the side wall. Along the length direction of the container body 110, neither the top corner piece 118 nor the bottom corner piece 112 protrudes from the outer end face of the end wall. This facilitates the transportation of the container.

[0085] Along the height direction of the base plate 120, the lower surface of the first lock body 131 (the surface of the first lock body 131 away from the top corner member 118 when the base plate 120 is in the closed position) is located on the upper side of the lower surface of the base plate 120 (the surface of the base plate 120 away from the top corner member 118 when the base plate 120 is in the closed position), near the upper lock head 132. Along the height direction of the base plate 120, there is a gap between the lower surface of the first lock body 131 and the lower surface of the base plate 120. The lower lock head 133 is located within the gap between the lower surface of the first lock body 131 and the lower surface of the base plate 120. This protects the lower lock head 133. When the base plate 120 is in the closed position, the height direction of the base plate 120 is parallel to the height direction of the housing 110.

[0086] This application also provides a discharge device. Please refer to... Figures 8 to 16 The unloading device is used for the aforementioned container. The unloading device includes an unloading rack 140, a tilting support 150, and a rotary lock assembly 160.

[0087] like Figures 10 to 16 As shown, the unloading rack 140 can be a circumferentially closed annular structure to enclose the internal space of the unloading rack 140. A portion of the internal space forms the unloading channel 141. The upper end of the unloading rack 140 has an upper opening. The lower end of the unloading rack 140 has a lower opening. The upper opening connects to the unloading channel 141. The lower opening connects to the internal space of the unloading rack 140.

[0088] The container can be moved to the first unloading position. The container located at the first unloading position is located within the unloading channel 141.

[0089] The tilting bracket 150 is disposed within the internal space of the unloading rack 140. The tilting bracket 150 is located outside the unloading channel 141. One end of the tilting bracket 150 is rotatably connected to the unloading rack 140. Thus, the tilting bracket 150 can rotate between a second unloading position and a flat position. When the tilting bracket 150 is in the flat position, the plane on which the tilting bracket 150 is located is perpendicular to the height direction of the unloading rack 140, that is, the tilting bracket 150 is horizontally positioned. When the tilting bracket 150 is in the second unloading position, the tilting bracket 150 is inclined to the height direction of the unloading rack 140.

[0090] Please refer to Figures 12 to 15 The rotary lock assembly 160 includes a second lock body 161 and a rotary lock head 162. The second lock body 161 is connected to the tilting bracket 150. The rotary lock head 162 is rotatably connected to the second lock body 161. The rotary lock head 162 is located on the side of the second lock body 161 near the upper end of the unloading rack 140.

[0091] When the container with the bottom plate 120 in the closed position moves to the first unloading position and the tilting bracket 150 is in the flat position, the rotary lock head 162 is connected to the lower lock head 133 to drive the upper lock head 132 to rotate.

[0092] In this embodiment, the unloading device includes the aforementioned container. The twist lock assembly 130 is used to lock the bottom plate 120, which is in the closed position, to the lower end of the container body 110. When it is necessary to unload the bulk cargo inside the container body 110, the upper lock head 132 can be rotated to the unlocked position so that the bottom plate 120 can leave the container body 110 and move to the open position, thereby unloading the bulk cargo inside the container body 110. Since the bottom opening 111 is large, construction waste including long wooden blocks, steel bars and cement blocks can be unloaded cleanly.

[0093] Preferably, such as Figure 12 and Figure 15 As shown, the rotary lock head 162 has a receiving groove 163. When the tilting bracket 150 is in the flat position, the opening of the receiving groove 163 faces the upper end of the unloading rack 140. When the container with the bottom plate 120 in the closed position moves to the first unloading position, and the tilting bracket 150 is in the flat position, the length direction of the lower lock head 133 and the length direction of the rotary lock head 162 are parallel to the length direction of the receiving groove 163, and the lower lock head 133 extends into the receiving groove 163. In this way, the rotary lock head 162 drives the lower lock head 133 to rotate through the receiving groove 163. This facilitates the connection of the lower lock head 133 to the rotary lock head 162.

[0094] Please refer to Figure 13 and Figure 14 The tilting bracket 150 has a locking plate 151. Along the height direction of the tilting bracket 150, the locking plate 151 is located on the side of the rotary lock head 162 near the upper end of the unloading rack 140. The locking plate 151 and the rotary lock head 162 are spaced apart.

[0095] The locking plate 151 has a bottom plate elongated hole 152. When a container with the bottom plate 120 in the closed position moves to the first unloading position, with the upper locking head 132 in the locked position and the tilting bracket 150 in the flat position, the long axis of the bottom plate elongated hole 152 is parallel to the length direction of the lower locking head 133. Thus, when a container with the bottom plate 120 in the closed position moves to the first unloading position, with the upper locking head 132 in the locked position and the tilting bracket 150 in the flat position, the second lock body 161 of the twist lock assembly 130 overlaps with the locking plate 151, and the lower locking head 133 passes through the bottom plate elongated hole 152 and enters the receiving groove 163 to connect to the twist lock head 162. At this time, the length direction of the lower locking head 133 is parallel to the length direction of the receiving groove 163. Therefore, the locking plate 151 can support the container body 110. It should be noted that when the tilting bracket 150 is in the flat position, the height direction of the tilting bracket 150 is parallel to the height direction of the unloading rack 140.

[0096] Please refer to Figures 8 to 16 After the lower locking head 133 enters the receiving groove 163, the rotating locking head 162 rotates so that the length direction of the rotating locking head 162 is offset from the long axis of the long hole 152 in the bottom plate, so that the lower locking head 133 is locked to the locking plate 151, thereby preventing the lower locking head 133 from leaving the rotating locking head 162.

[0097] When the length of the locking head 132 is parallel to the long axis of the corner fitting's elongated hole 113, the tilting bracket 150 can be rotated toward the second unloading position, thereby causing the bottom plate 120 to leave the box 110 and move toward the open position. In this way, the bulk goods inside the box 110 can be unloaded.

[0098] like Figures 4 to 7 , Figure 12 , Figure 14 Yu and Figure 15As shown, after the bulk cargo inside the container 110 is unloaded, the tilting bracket 150 can be rotated to a flat position, allowing the upper locking head 132 to enter the bottom corner fitting 112 through the corner fitting elongated hole 113. At this time, the rotary locking head 162 can be rotated until its length is parallel to the long axis of the bottom plate elongated hole 152. At this point, the length direction of the upper locking head 132 is offset from the length direction of the corner fitting elongated hole 113, and the upper locking head 132 locks the bottom plate 120 to the container 110. At this time, the length direction of the lower locking head 133 is parallel to the long axis of the bottom plate elongated hole 152. Moving the container upwards allows the lower locking head 133 to move upwards through the bottom plate elongated hole 152, moving away from the locking plate 151.

[0099] like Figures 4 to 7 , Figure 12 , Figure 14 and Figure 15 As shown, with the flip bracket 150 in the flat position and the base plate 131 in the closed position, the long axis of the corner piece elongated hole 113 is parallel to the long axis of the base plate elongated hole 152. The length direction of the upper locking head 132 is perpendicular to the length direction of the lower locking head 133. Thus, when the length direction of the upper locking head 132 is parallel to the long axis of the corner piece elongated hole 113, the length direction of the lower locking head 133 is perpendicular to the long axis of the base plate elongated hole 152. At this time, the lower locking head 133 can be locked to the locking plate 151, and the upper locking head 132 can be disengaged from the bottom corner piece 112. When the length direction of the upper locking head 132 is perpendicular to the long axis of the corner piece elongated hole 113, the length direction of the lower locking head 133 is parallel to the long axis of the base plate elongated hole 152. At this time, the upper locking head 132 can be locked to the bottom corner piece 112, and the lower locking head 133 can be disengaged from the locking plate 151. In this way, rotating the pivot 134 can lock the upper locking head 132 to the bottom corner piece 112 and allow the lower locking head 133 to move away from the locking plate 151, or lock the lower locking head 133 to the locking plate 151 and allow the upper locking head 132 to move away from the bottom corner piece 112.

[0100] The bottom plate 120 is detachably connected to the container body 110 via a twist-lock assembly 130. The bottom plate 120 is also detachably connected to a tilting bracket 150 located in a flat position via the twist-lock assembly 130. Thus, during the transport of bulk cargo, the bottom plate 120 is connected to the container body 110. When it is necessary to unload the bulk cargo from the container body 110, the tilting bracket 150 can be moved to a flat position, and the container can be moved to a first unloading position, thereby rotating the twist lock head 162 to fix the bottom plate 120 to the tilting bracket 150. This allows the bottom plate 120 to leave the container body 110. At this point, rotating the tilting bracket 150 to a second unloading position will move the bottom plate 120 away from the container body 110, thereby unloading the bulk cargo from the container body 110. Therefore, unloading the bulk cargo from the container body 110 is relatively convenient.

[0101] like Figure 10 and Figure 16 As shown, the unloading rack 140 has a limiting part 142. The limiting part 142 is located within the unloading channel 141. The limiting part 142 is connected to the inner wall of the unloading rack 140 that forms the unloading channel 141. The limiting part 142 protrudes from the inner wall. When the container is in the first unloading position, the container bracket 115 overlaps with the limiting part 142 so that the limiting part 142 is supported on the container body 110.

[0102] Preferably, such as Figure 10 and Figure 16 As shown, the unloading rack 140 includes an upper unloading rack 144 and a lower unloading rack 145 located below the upper unloading rack 144. An unloading channel 141 is located within the upper unloading rack 144. The upper unloading rack 144 and the lower unloading rack 145 are connected. Along the width direction of the unloading rack 140, the dimension of the lower unloading rack 145 is larger than the dimension of the upper unloading rack 144. Thus, a stepped structure is formed between the lower unloading rack 145 and the upper unloading rack 144. A tilting bracket 150 is rotatably connected to the lower unloading rack 145. When the container is located within the unloading channel 141, the width direction of the unloading rack 140 is parallel to the width direction of the container. Therefore, since the dimension of the upper unloading rack 144 is smaller than the dimension of the lower unloading rack 145, the material consumption of the unloading rack 140 can be reduced.

[0103] Preferably, please continue to refer to Figure 10 and Figure 16 When the container is in the first unloading position, the upper end of the container body 110 is above the upper end of the unloading rack 140. This facilitates the lifting of the container.

[0104] The unloading device also includes a first drive assembly (not shown). The first drive assembly is disposed on the tilting bracket 150. The first drive assembly is connected to the rotary lock head 162 for driving the rotary lock head 162 to rotate.

[0105] The unloading device also includes a second drive assembly (not shown). The second drive assembly is disposed on the unloading rack 140. The second drive assembly is connected to the tilting bracket 150 for driving the tilting bracket 150 to rotate. Thus, when the container is in the first unloading position, the bottom plate 120 can be automatically rotated between the closed position and the open position by the operation of the first drive assembly and the second drive assembly.
