As shown in fig. 1, the present invention provides an open-bottom container 100 that enables the discharge from the bottom of the container 100.
Fig. 1 schematically shows the overall structure of the container 100, and as can be seen from fig. 1, the container 100 may include a front wall, two side walls, an end door disposed opposite the front wall, a bottom frame 110 at the bottom, and a bottom plate 120 disposed on the bottom frame 110. Among other things, the underframe 110 may include two lengthwise extending bottom side rails 112 and a plurality of widthwise extending bottom cross rails 115. The bottom cross member 115 can be connected to the bottom side member 112. The top of the container 100 may be provided with a feed inlet to facilitate loading. For example, the top of the container 100 is open to form a feed throat, in which embodiment a removable tarpaulin or like cover may be used to cover the open top; alternatively, the container 100 includes a top wall from which the feed ports may be located.
To achieve discharge from the bottom of the container 100, the chassis 110 is provided with a discharge hatch 111, the floor 120 can be provided at the discharge hatch 111, and the floor 120 can be pivoted about a pivot axis between a closed position covering the discharge hatch 111 and an open position leaving the discharge hatch 111 open. The bottom plate 120 in the closed position is horizontal and can carry material, and the bottom plate 120 in the open position is inclined downward, at which time the discharge port 111 is opened, so that it is possible to discharge material from the discharge port 111. The bottom chassis 110 may also be provided with a bearing part 113, and the bearing part 113 is located between the adjacent bottom plates 120. The bearing portion 113 includes a bottom beam 115 and a base plate disposed on the bottom beam 115. The substrate forms a generally flat carrying surface with the base plate 120 in the closed position. Optionally, a slot 114 may be disposed in the bearing portion 113.
The container 100 may include at least two floors 120. The chassis 110 is provided with at least two discharge ports 111. The base plates 120 can correspond one-to-one to the discharge ports 111. That is, each bottom plate 120 is used to cover one discharge hole 111.
The container 100 also includes a plurality of reset devices 130 for resetting the base plate 120. The reset device 130 may be disposed on the bottom chassis 110 and connected to the base plate 120. A plurality of reset devices 130 can be respectively arranged corresponding to each base plate 120. That is, each base plate 120 may be correspondingly provided with the reset device 130. Thus, the reset of each backplane 120 can be achieved independently by its own reset device 130, without interfering with the reset of the other backplanes 120. The container 100 may further comprise a locking mechanism 150, the locking mechanism 150 being able to be arranged on the base frame 110, in particular on the bottom cross member 115. Specifically, the base plate 120 may include a pivoted end 121 and a locking end 122 opposite the pivoted end 121. The pivoting end 121 of the base plate 120 can be connected to the base frame 110 by a pivot shaft 123 (fig. 2) having a pivot axis. The locking end 122 can be cooperatively connected with a locking mechanism 150 to control the opening and closing of the base plate 120. It will be appreciated that the pivot axis 123 may be a long axis or may be a plurality of spaced short axes.
The reset device 130 in this embodiment can provide an upward biasing force to the bottom plate 120, so that the bottom plate 120 is automatically reset from the open position to the closed position, and reset is achieved. It will be appreciated that the biasing force herein is slightly greater than the gravitational force of the base plate. In this embodiment, the bottom plate 120 in the open position can be automatically moved to the closed position by the biasing force of the reset device 130 when the discharge is completed. And the container 100 has the advantages of simple structure, easy processing, flexible, simple and fast unloading operation, low cost, strong universality and the like.
The restoring means 130 may comprise an elastic member 131 (fig. 2). The elastic member 131 can provide an upward elastic force to the base plate 120, i.e., the biasing force is an elastic force. In this embodiment, the floor panel 120 can be automatically rebounded from the open position to the closed position by means of the elastic force of the elastic member 131, and the return of the floor panel 120 is not achieved by means of the operation force of a user or the driving force of a driving device, for example, which enables the structure of the return device 130 to be simplified, thereby simplifying the structure of the container 100, facilitating the production and manufacture of the container 100, and reducing the manufacturing cost. The resetting device 130 of this embodiment has strong versatility, and can improve the market competitiveness of the container 100.
When the material needs to be discharged, the locking mechanism 150 can be opened, the locking end 122 of the bottom plate 120 is separated from the locking mechanism 150 under the action of the gravity of the material, and the bottom plate 120 automatically moves to the opening position to start the material discharging; when the discharging is completed, the gravity of the material disappears, the bottom plate 120 automatically resets by the elastic force of the elastic member 131, and then the locking mechanism 150 is unlocked, so that the locking end 122 of the bottom plate 120 is fixed on the bottom frame 110 by the locking mechanism 150.
The reset device 130 may be provided with at least two, e.g., two, three, four, etc., along the pivot axis of the base plate 120. Therefore, the base plate 120 can be subjected to elastic forces at different positions, and the resetting action of the base plate 120 is more stable. The projection of the resetting device 130 on the horizontal plane can be located within the projection area of the chassis 110 on the horizontal plane. Thus, the reset device 130 is not visible when viewed from the top of the container 100 down or from the side of the front or door end of the container 100, thereby not affecting the external structure of the container 100.

The plate spring 131c can provide an upward pushing force to the base plate 120, i.e., an elastic force is a pushing force.
In other embodiments, the elastic member 131 may also be an air spring, but may also be any other element that can provide an elastic force.
Fig. 8 and 9 show a third embodiment of the resetting means 130, in which embodiment the resetting means 130 comprises a cylinder 231, the cylinder 231 being arranged below the pivot axis of the base plate 120. Specifically, the base plate 120 includes a pivoting portion 124 disposed at the pivoting end 121 and a connecting member 125, and the connecting member 125 is disposed at a distance from the pivoting portion 124 in a direction perpendicular to the pivoting axis. The cylinder 232 of the air cylinder 231 is connected to the base frame 110, and the piston rod 233 of the air cylinder 231 is connected to the base plate 120. The cylinder 231 can provide a downward pushing force and an upward pushing force to the base plate 120. In other embodiments, the cylinder 231 may be replaced by a hydraulic cylinder, but may be any other actuator capable of pushing.
Fig. 10-13 show different embodiments of the container 100, wherein the arrangement of the floor 120 is different. In other words, the reset device 130 provided by the present invention can be applied to the base plate 120 with various arrangements. In particular, fig. 10 and 11 show that at least three bottom plates 120 may be provided in the length direction of the base frame 110, and the pivot axis may extend in the width direction of the base frame 110. The pivoting directions of the adjacent bottom plates 120 may be the same. Alternatively, the pivoting directions of adjacent bottom panels 120 may be opposite, with the adjacent bottom panels 120 in the open position facing or away from each other.
For example, two bottom plates 120 of the three bottom plates 120 are shown in fig. 1 as split bottom plates 120, and the other bottom plate 120 pivots in the same direction as any one of the split bottom plates 120. Fig. 10 shows that the three bottom plates 120 all have the same pivoting direction, i.e., are arranged in the same direction as the flip bottom plates 120.
