Detailed Description

The invention provides a bulk container with a novel opening and closing system, which can be used for loading and transporting bulk materials, and when the bulk container is positioned in a storage yard, a container portal crane can be used for stacking and storing the materials in the form of the container storage yard, so that the dust pollution during stacking and storing the bulk materials is reduced. The shape, size and the like of the container of the invention are the same as those of the container in the prior art, so the transport carrier of the container of the invention can use the transport carrier of the prior container. The container will be described in detail with reference to fig. 1 to 10.

The container corner position is equipped with a positioning screw lockhole seat 3, and the top and the bottom are respectively provided with a charging mechanism and a discharging mechanism.

The charging mechanism comprises a bearing roller body 1, a top door panel 4, an anti-tilt baffle 5, a roller groove and a driving component for controlling the opening and closing of the top door panel 4. The roller groove is arranged at the top of the container along the length direction of the container, a bearing roller body 1 is arranged in the roller groove, and a top door panel 4 is pressed on the bearing roller body 1. The top door panel 4 may be one piece or two pieces. The driving component drives the top door panel 4 to move on the bearing roller body 1 along the arrangement direction of the roller grooves. In order to avoid toppling when the top door panel 4 moves to the two ends of the container, anti-toppling baffles 5 are arranged at the two ends of the top of the container. The anti-roll bar 5 is mounted along the width of the container and above the top door panel 4. The present invention is not limited to the driving assembly, and the driving assembly may include a rack 6 and a gear motor 15. The rack 6 is arranged on one side of the top door panel 4, and a gear rack engaging groove 7 is formed in the container shell 9 at the corresponding position. The container spreader 14 is provided with a gear motor 15, after the container spreader 14 is positioned and butted with a container, the gear motor 15 is meshed with the rack 6 at the gear and rack meshing groove 7, and the top door panel 4 is driven to open and close by the gear motor 15. The gear motor 15 may be powered and controlled by a power supply and control mechanism on the spreader 14. In addition, the gear motor 15 can be replaced by a gear provided with a manual rotating handle, and the opening and closing of the top door panel 4 can be completely controlled manually.

The container spreader 14 utilizes the existing standardized container spreader, and can be used for controlling the opening and closing of the top door panel 4 of the container of the invention after being additionally provided with the gear motor 15. The mass of the cargo in the weighing hopper can be converted into the mass of the bulk cargo in the weighing hopper by measuring the tension on the steel wire rope of the container spreader 14 through the tension sensor.

The discharging mechanism comprises a discharging door plate 2 and a discharging control rotary lock 10 which controls the discharging door plate 2 to open and close to prevent the discharging door plate from being suddenly opened. Two discharging door panels 2 are arranged at the bottom of the container shell 9 in a double-door mode through hinges. One end of the discharging door panel 2 is a hinge, one side of the other end is provided with a twist lock hole 12 and a pulley groove 16, and the other side of the other end is provided with a pulley 11. When the two discharging door panels 2 are closed, the pulley 11 of one discharging door panel is accommodated in the pulley groove 16 of the other discharging door panel. The discharge control rotary lock 10 is arranged on the container shell 9. When the discharging door panel 2 is closed, the tapered end of the discharging control rotary lock 10 is just positioned in the rotary lock hole 12 of the discharging door panel 2. The unloading control rotary lock 10 comprises a motor, a battery, a rotary lock and a control terminal. Under the condition of power supply of the battery, the motor is remotely operated by using the control terminal to control the opening and closing of the spin lock, and the unloading door plate 2 does not need to be manually opened and closed in a short distance.
