[0002] Using containers to transport grain not only effectively prevents damage from severe weather but also prevents spillage during transport. Currently, the mainstream containers for grain transport are dry cargo containers. However, due to the characteristics of grain, it undergoes respiration during transport, generating heat and moisture, causing some grain to spoil and become inedible, thus increasing the grain loss rate. Furthermore, inert gases are typically used to prevent spoilage, but dry cargo containers have poor sealing and insulation properties. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an unloading door and an insulated bulk cargo container to solve one or more of the above-mentioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A discharge gate includes an outer panel and an inner panel. The outer panel and the inner panel are provided with interlaced transverse and longitudinal reinforcing ribs. The outer panel and the inner panel have through-holes for air filling. An air filling nozzle is provided at the outer end of each air filling hole. An insulation layer is provided inside the inner panel.

[0006] Furthermore, the outer panel and the inner panel of the small door are connected at their upper and lower ends by an integrally formed outer door frame and inner door frame. The upper end of the outer panel is bolted to the outer door frame, the lower end of the outer panel is welded to the outer door frame, and the upper and lower ends of the inner panel are inserted into the inner door frame.

[0007] Furthermore, the outer door frame has an L-shaped structure, with a recessed outer frame groove at one end. The opening end of the outer frame groove has a flared structure, and the top of the connection end between the outer frame groove and the inner door frame has a flared structure. The flared structure is located at the thin plate section of the outer door frame and the outer end of the inner door frame.

[0008] Furthermore, the inner door frame has an L-shaped structure, with an insertion groove at one end. The opening side of the insertion groove has different lengths. The other end of the inner door frame has a recessed inner frame groove. The opening end of the inner frame groove has a hook structure, and a V-groove seat is provided at the center of the inner bottom surface of the inner frame groove.

[0009] The insulated bulk container includes the aforementioned unloading door. An opening is provided at the lower front end of the container. The upper end of the opening is hinged to the unloading door via a hinge plate. A threshold is provided at the lower end of the opening. A bolt is provided at the lower end of the unloading door.

[0017] Example:

[0018] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0019] A type of unloading door and insulated bulk container, such as Figure 1As shown, the unloading door is installed in an opening below the front end of the insulated bulk cargo container, and a threshold 14 is provided at the lower end of the opening. A hinge plate is provided at the upper end of the container opening, and the movable end of the hinge plate is connected to both the outer panel 1 and the inner panel 2 of the unloading door. The unloading door flips relative to the container opening through the hinge plate. The threshold 14 of the container opening limits the flipping range of the unloading door. A pin locking rod 15 is provided at the lower end of the unloading door, and a corresponding bolt seat is provided on the threshold 14. Two sets of pin structures are symmetrically arranged on the left and right sides. The unloading door is separated from or fixed to the container through the pin locking rod 15 and the bolt seat.

[0020] like Figure 3 As shown, the unloading gate mainly consists of an outer small door panel 1 and an inner small door panel 2. The outer small door panel 1 is connected to the latch locking rod 15 and the hinge plate. Transverse reinforcing ribs 3 and longitudinal reinforcing ribs 4 are staggered between the outer small door panel 1 and the inner small door panel 2; the spacing and number of these ribs are determined according to customer requirements and container dimensions. The upper and lower ends of the outer small door panel 1 and the inner small door panel 2 are connected and fixed via an outer door frame 6 and an inner door frame 7. The upper end of the outer small door panel 1 is directly bolted to the outer door frame 6 via the hinge plate, and the lower end of the outer small door panel 1 is welded to the outer door frame 6. The upper and lower ends of the inner small door panel 2 are inserted into the inner door frame 7. The inner door frame 7 and the outer door frame 6 are integrally formed. Figure 2 As shown, air inlets are provided on both the outer and inner panels of the small door. These air inlets can be aligned and connected to ensure that the inside and outside of the housing can exchange or replenish gas after the unloading door is installed. An air inlet 5 is located at the outer end of each air inlet. The air inlet 5 serves three purposes: enhancing airtightness, allowing for air replenishment or release, and providing temporary pressure relief. The inner panel of the small door has a sandwich structure filled with insulation material, forming an insulation layer.

[0021] like Figure 3 As shown, the outer door frame 6 has an L-shaped structure. The vertical corner section is bolted or welded to the inner panel 2 of the small door. The horizontal corner section has a recessed outer frame groove 8. The opening end of the outer frame groove 8 has a ridge structure to secure the subsequent sealing strip and prevent easy detachment. The section of the horizontal section of the outer door frame 6 that connects to the inner door frame 7 is a thin plate section 10, the thickness of which is smaller than the outer frame groove 8 and the vertical corner section. The ridge structure of the outer frame groove 8 has an outward-facing ridge 9 on the side near the inner door frame 7. The ridge 9 is located at the outer end of the thin plate section 10 and the inner door frame 7. The inner door frame 7 has an L-shaped structure. The vertical corner section of the inner door frame 7 has an insertion groove 11. The opening side of the insertion groove 11 has different lengths, generally shorter at the end closer to the unloading door, so that the insertion is more secure. The inner door frame 7 has a recessed inner frame groove 12 at the horizontal corner section. The opening end of the inner frame groove 12 has a hook structure. The difference between the hook structure and the eave structure is that the hook end has a hook head, which can be used with the hook head specially set on the corresponding rubber strip to form mutual hooking, making the installation more stable. A V-groove seat 13 is provided at the center of the inner bottom surface of the inner frame groove 12.

[0022] like Figure 2 and Figure 3 As shown, an outer rubber strip 16 and an inner rubber strip 17 are inserted into the gap between the unloading gate and the insulated bulk cargo container at the top and bottom. The outer rubber strip 16 has a hook at its end, which is installed into the eaves structure of the outer frame groove 8. The inner rubber strip 17 also has a hook structure extending to both sides at its end, corresponding to the hook structure of the inner frame groove 12. The end face of the inner rubber strip 17 is concave at the center and has symmetrical concave edges, corresponding to the V-groove seat 13, which is designed to enhance the installation stability of the inner rubber strip 17, the inner frame groove 12 and its V-groove seat 13. The main body of both the outer rubber strip 16 and the inner rubber strip 17 are offset towards the center of the unloading gate.

[0023] In use, the insulated bulk cargo container is rotated 90° using a specialized tilting mechanism so that the end with the unloading door faces downwards, keeping the front unloading door closed. The rear door is opened, and grain is poured in. Once full, the rear door is closed, and the container is rotated in the opposite direction to return to its original position. Nitrogen is then injected into the container using the inflation nozzle 5 on the front unloading door until the nitrogen sensor 18 indicates that the level is met. Inflation is then stopped, and an external supplementary gas cylinder is connected. During transportation, the interior of the container is monitored using the nitrogen sensor 18 and the temperature sensor 19, and nitrogen is replenished and the temperature is adjusted as needed. Upon arrival at the destination, the latch lever 15 is pulled out and rotated, and the grain inside is automatically discharged out of the container. The unloading door and hinge plate are then rotated, and the rubber strip automatically disengages, completing the unloading process.

[0024] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
