Abstract
Description
Technical Field
[0001] This utility model relates to the field of containers, specifically a grain container. Background Technology
[0002] Currently, the mainstream grain containers are dry cargo containers. Grains are stored inside dry cargo containers. During the transportation of grains in dry cargo containers, the grains will breathe, generating heat and moisture, causing most of the grains to spoil and become inedible, resulting in an extremely high grain loss rate.
[0003] To reduce grain loss, inert gas can be added inside the container to inhibit grain respiration. However, older dry cargo containers have more gaps and higher leakage rates, making the cost of filling them with gas higher. Utility Model Content
[0004] The purpose of this invention is to provide a grain container to reduce air intake costs and grain loss rate.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a grain container, comprising a container body, wherein the container body is an insulated container body for storing grain; a filling hole is provided at the top of the container body for injecting grain; the filling hole is equipped with a filling hole cover, which covers the filling hole; two ends along the length direction of the container body are respectively provided with a discharge door and an air injection hole, wherein the discharge door is used to discharge grain; the air injection hole is located at the upper center of the end and is used to inject inert gas into the interior of the container body, wherein the inert gas is used to suppress the respiration of the grain inside the container.
[0006] Preferably, the box body includes a top plate, side plates, end plates, bottom plate, and unloading door filled with thermal insulation material. The end plates and the unloading door are located at two ends of the box body along its length. The top plate is provided with the injection hole and the injection hole cover, and the end plates are provided with the air injection hole.
[0007] Preferably, the air injection port is equipped with a sealing cap that covers the air injection port.
[0008] Preferably, a sealing strip is provided on the inner side of the sealing cover to enhance the sealing performance between the sealing cover and the end plate.
[0009] Preferably, the back side of the injection hole cover is connected to the top plate via a hinge flipping mechanism and a locking rod device, and a sealing strip is provided on the inner side of the injection hole cover to enhance the sealing between the injection hole cover and the top plate.
[0010] Preferably, the unloading door is provided with a C-shaped door seal structure on the side facing the inside of the box to enhance the sealing performance of the unloading door.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses an insulated container that maintains a constant temperature and is not prone to air leakage to load and transport grains, which can make up for the defects of dry freight containers. At the same time, inert gas is injected through the opening at the front of the container, thereby inhibiting the respiration of the grains and reducing the damage rate. Attached Figure Description

[0017] Please see Figures 1 to 5 This utility model discloses a grain container, including a container body 1 for storing grain. The container body 1 is an insulated container body, including a top plate 11, side plates 12, end plates 13, bottom plate and unloading door 14 filled with insulation material 2. The end plates 13 and unloading door 14 are located at two ends along the length direction of the container body 1, respectively.
[0018] The top plate 11 has an injection hole for injecting grains; the injection hole is equipped with an injection hole cover 4, which covers the injection hole. The back side of the injection hole cover 4 is connected to the top plate 11 via a hinge flipping mechanism 5 and a locking rod device 6. A sealing strip 7 is provided on the inner side of the injection hole cover 4 to enhance the sealing between the injection hole cover 4 and the top plate 11.
[0019] The end plate 13 has an injection hole 3, which is located in the center of the upper side of the end plate 13. This hole is used to inject inert gas into the interior of the housing 1. The injection hole 3 is equipped with a sealing cap (not shown in the attached diagram). The sealing cap closes to the injection hole 3. The sealing cap is opened when injection is needed, and closed during transportation of the housing 1 when the injection hole 3 is not required. A sealing strip 7 is provided on the inner side of the sealing cap to enhance the seal between the sealing cap and the end plate 13.
[0020] Inert gas can inhibit the respiration of grains inside the box. Before filling the box 1 with grains, some inert gas can be injected into the box through the air injection hole 3. Because inert gas is relatively heavy, it will sink to the bottom of the box and will not overflow the box 1. Then, grains are injected through the filling hole. At this time, inert gas is mixed in with the grains. After the box is full of grains, inert gas is injected again through the air injection hole 3 to achieve the purpose of inhibiting grain respiration.
[0021] The unloading door 14 is used to unload grains after they arrive at the destination. During transportation, in order to ensure airtightness, a C-type door seal structure 8 can be installed on the side of the unloading door 14 facing the inside of the box 1. The C-type door seal structure 8 is a commonly used door seal structure and has stronger airtightness than other commonly used structures, thereby enhancing the airtightness of the entire box 1 and preventing inert gas from overflowing.
[0022] In summary, this utility model uses an insulated container that maintains a constant temperature and is not prone to air leakage for loading and transporting grains, which can make up for the shortcomings of dry freight containers. At the same time, the front opening of the container is used to inject inert gas, and the rear door adopts a C-type door seal structure to ensure airtightness, so that the inert gas injected into the container is not easy to escape, thereby inhibiting the respiration of the grain and reducing the damage rate.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
