[0002] At present, most of the bulk material bin unloading devices are simple manual opening devices, which are low in cost and must be opened by manual or tools. Once the material device is out of control, a large amount of material will bury the operator inside, causing suffocation accidents. The motor control opening is used, but it cannot meet the safety requirements of corrosion and explosion prevention, and can only be installed outside the material bin, which causes the air tightness and thermal insulation of the material bin to fail to meet the standard.

[0006] Further, the inclination angle of the inclined discharge channel is 45°.
[0007] Further, the number of inclined discharge channels is one, two or more.
[0008] Further, the discharge port cover plate is tightly combined with the upper port to form a first layer of thermal insulation airtight door.
[0009] Further, the bin outside discharge port thermal insulation airtight door and the lower port form a second layer of thermal insulation airtight door, a hinge door is arranged on the bin outside discharge port thermal insulation airtight door, and the hinge door is opened electrically or manually.
[0010] The present application has the following advantages:
[0011] 1. The present application has high safety. Artificial close operation is avoided, and the bulk material covers the operator, causing suffocation and personal safety accidents;
[0012] 2. The present application greatly improves the heat preservation and air tightness of the bulk material warehouse. The corrosion and explosion-proof servo motor device is installed inside the bulk material warehouse, and the discharge port cover plate and the discharge port form the first layer of heat preservation and air tightness door, and the second layer of heat preservation and air tightness door is installed outside the material warehouse;

[0019] In order to make the purpose, technical scheme and advantages of the present application more clear and obvious, the present application will be described below through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.
[0020] Embodiment:
[0021] Referring to Figures 1 to 4 description of the present embodiment, the present embodiment provides a bulk material safety unloading device,
[0022] One, two or more 45° discharge channels are opened in the outer wall of the bulk material warehouse, and the corrosion and explosion-proof servo motor device 1 is arranged on the inner side of the outer wall 7 of the bulk material warehouse. The corrosion and explosion-proof servo motor device 1 is connected with the discharge port cover plate 3 through the telescopic rod 2. The telescopic length of the telescopic rod 2 is controlled by program and fixed. When the telescopic rod 2 is extended to the longest, the discharge port cover plate 3 can cover the upper port completely, and when the telescopic rod 2 is extended to the shortest, the lower port can be exposed completely.
[0023] Specifically, when the anticorrosive and explosion-proof servo motor 1 drives the telescopic rod 2 to contract, the discharge port cover plate 3 is displaced, and the upper port is not covered by the discharge port cover plate 3, at this time, the upper port is in an open state, at this time, the hinge door 6 of the discharge port heat preservation airtight door 5 outside the bin is also opened, and the material starts to flow, so that the discharge function can be realized.
