Discharging opening of bulk cargo box

Abstract

The utility model discloses a bulk container discharge port which comprises a container rear end door, and an installation box is fixedly connected to the inner wall of the container rear end door. When discharging is needed, the external discharging door is firstly opened, the flow guide plate is overturned forwards, the handle is rotated clockwise under the overlook projection to open the valve plate, discharging can be started, when discharging needs to be stopped, the handle is rotated anticlockwise under the overlook projection to close the valve plate, then the flow guide plate is overturned upwards, and discharging can be stopped. When the valve plate is opened, the external discharging door is closed after peripheral excess materials are cleaned, controllability of the discharging door is higher, one box of bulk cargoes can be discharged in different places in a graded mode, and the situation that the valve plate is opened by mistake due to the fact that the pressure of the internal bulk cargoes is not uniform after the valve plate is closed or materials are extruded out of one side of the valve plate due to jolting in the transportation process is avoided through cooperation of the limiting pin and the limiting hole; when the valve plate needs to be opened, the handle can be rotated only by pulling the pull ring downwards to enable the limiting pin to be separated from the limiting hole, safety is high, and use is very convenient.

Description

Technical Field

[0001] The utility model relates to the technical field of bulk cargo containers, in particular to a bulk cargo container discharge port. Background Art

[0002] Bulk containers are generally used to store small granular goods such as grains and beans. Existing bulk containers are provided with a small discharge port on the door end panel (which can also be used as a pressure relief port) and a large discharge port at the front end. For example, a container discharge door proposed in the public technology on the market is installed on the discharge port of the container body. The container discharge door includes an outer door located outside the discharge port and a tipping bucket located inside the discharge port, and the tipping bucket is flippably installed on the discharge port. The discharge door provided by the technology is composed of an outer door and a tipping bucket. The outer door and the tipping bucket are opened sequentially during discharge. The setting of the tipping bucket can guide the outflow of goods, which is convenient for packaging and will not be scattered on the ground. Moreover, the common setting of the outer door and the tipping bucket facilitates the double sealing of the discharge port, ensuring the sealing of the discharge port when the discharge door is closed.

[0003] However, other prior arts including the above-mentioned prior arts have the defect that when the box is fully loaded with goods (or when there are a lot of bulk goods), if only a small amount of goods are unloaded, after opening the discharge (pressure relief) port, it is very difficult to close the discharge port when all the goods are not unloaded. Therefore, it is necessary to improve and optimize the structure of the discharge port of the bulk cargo box. Utility Model Content

When unloading needs to be stopped, turn the handle counterclockwise in a bird's-eye view to close the valve plate, flip the guide plate upward, clean the surrounding residual material and close the external discharge door. The discharge door is more controllable, and a box of bulk cargo can be unloaded in batches at different locations.

[0018] 2. Compared with the prior art, the bulk container discharge port is provided with a limit pin and a limit hole to prevent the valve plate from opening accidentally due to uneven pressure of bulk cargo inside or material being squeezed out from one side of the valve plate due to bumps during transportation after the valve plate is closed. When the valve plate needs to be opened, it is only necessary to pull the pull ring downward to disengage the limit pin from the limit hole and then turn the handle, which is highly safe and easy to use.
