Description

Technical Field

[0001] The invention belongs to the technical field of containers, and in particular relates to a bulk cargo container. Background Art

[0002] In today's logistics and transportation field, with the widespread popularity of container transportation and the continuous advancement of technology, the trend of containerized transportation of bulk goods has become increasingly significant. This transportation mode has greatly improved transportation efficiency and effectively reduced the loss of goods during transportation and the pollution to the environment, especially in areas with strict environmental requirements. For bulk goods such as coal, ore, and grain that are easily damaged or pollute the environment, containerized transportation has become a powerful means to protect the environment and improve the overall efficiency of logistics.

[0003] However, the top covers currently used in bulk containers have obvious defects. The existing integral top covers have the advantage of a large top opening and can meet higher loading efficiency, but due to their heavy weight, they can only be operated by overall lifting and cannot be operated manually. This greatly limits the flexibility and convenience of operation in actual application scenarios. The design of multiple top covers, although the top covers are lighter and easier to open manually, has a small top opening, which directly leads to low loading efficiency. Summary of the invention

[0004] The present invention aims at solving the defects in the prior art and provides a bulk container.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a bulk container, comprising a container body; in the top cover structure of the container body, the top cover opening is an integral opening; and the top cover structure comprises at least two independent top covers, and one side of each top cover is hinged to the container body and can be opened independently; two adjacent top covers are overlapped.

[0006] The top cover is a double-layer sealed top cover, and a sealing device is provided between the double-layer sealed top cover and the container body to ensure the sealing after the top cover is closed.

[0007] Furthermore, the overall opening is an opening on the top plate, and a horizontal top opening lip and a vertical top opening lip are provided on the top plate; in the top cover structure, the top plate and each lip are spliced ​​into a whole through an integrated bending process of the patterned plate, and overlapping notches are provided at the overlapping positions of the top covers, so that adjacent top covers can cover each other tightly.

[0008] Furthermore, the cover plate of the top cover adopts a box-type structure and is reinforced by a reinforcing groove, a top cover sealing strip is embedded in the groove, and a secondary sealing strip is clamped on the outer edge of the cover plate to form a double-layer sealed top cover.

[0009] Furthermore, an Ω-shaped overlapping cover plate is provided between two adjacent top covers, and the cover plate is connected to the top covers via a groove structure to form an outer package structure.

[0010] Furthermore, a handle is provided on the top cover, and the top cover structure is also equipped with a top cover locking rod. When locked, the top cover locking rod presses the top cover tightly onto the container body.

[0011] Furthermore, a discharge port is arranged at the bottom of the container body, and a discharge plate is arranged at the discharge port for shielding the discharge port. The discharge plate is slidably connected to the discharge port, and the discharge port can be opened or closed by pulling.

[0012] Furthermore, a handle and a lock box are provided on the unloading plate, and a lock nose is provided in the lock box. When the unloading plate is in a state of closing the unloading port, the lock nose is exposed outside the unloading plate and is used to lock the unloading plate to the container body.

[0013] Furthermore, a positioning angle steel is arranged above the discharge port, and the positioning angle steel is fixedly connected to the container body. The positioning angle steel is used as a guide component to guide the movement of the discharge plate. The positioning angle steel is also used to waterproof the top of the discharge port. At least two track round steels are installed at the bottom of the discharge port, and each track round steel is provided with a track wheel to ensure the smooth movement of the discharge plate; the positioning angle steel and the track round steel form a sliding track to support the discharge plate.

[0014] Furthermore, a discharge baffle is provided on the container body, and after the discharge baffle is opened to the maximum limit, the discharge baffle prevents the discharge baffle from further moving to avoid over-opening.

[0015] Furthermore, a guide plate is fixedly connected to the inner wall of the container body to guide the material flow path to avoid material accumulation or dead corners.

[0016] Compared with the prior art, the present invention has beneficial effects.

[0017] The top opening of the present invention is designed as an integral opening, which is convenient for rapid loading of goods and improves loading efficiency. It also adopts a split small top cover overlap type, which is easy to operate, and can flexibly open different numbers of top covers according to actual needs to meet various loading requirements. The double-layer seal of the top cover can further enhance the sealing after the top cover is closed, effectively preventing external impurities such as rainwater and dust from entering the box, and protecting the goods from contamination. In addition, the discharge port has many significant advantages such as efficient unloading, strong adaptability, low cost, easy operation and maintenance, and high reliability.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and beneficial effects of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0031] like Figure 1-11As shown, in a specific embodiment, the bulk container includes a container body; in the top cover structure of the container body, the top cover opening is an integral opening; and the top cover structure includes at least two independent top covers, and one side of each top cover is hinged to the container body and can be opened independently; two adjacent top covers are overlapped. The top cover is a double-layer sealed top cover, and a sealing device is provided between the double-layer sealed top cover and the container body to ensure the sealing after the top cover is closed.

[0032] Embodiment 1: The overall opening adopts an opening on the top plate, and a horizontal top opening lip and a vertical top opening lip are provided on the top plate; in the top cover structure, the top plate and each lip are spliced ​​into a whole through the integrated bending process of the patterned plate, and overlapping notches are provided at the overlapping positions of the top covers, so that adjacent top covers can cover each other tightly. Among them, the top opening is designed as an overall opening. Compared with the multi-point or partial openings of traditional bulk containers, the overall opening design is more convenient for rapid loading and unloading of goods, thereby improving loading efficiency. Moreover, the split small top cover (i.e., independent top cover) overlaps: it means that the top cover is divided into multiple small top covers, and these small top covers can be opened in sequence. This design is not only easy to operate, but also can flexibly open different numbers of top covers according to actual needs to meet a variety of loading needs.

[0033] Example 2: The cover plate of the top cover adopts a box-shaped structure and is reinforced by a reinforcement groove. The top cover sealing strip is embedded in the groove, and the secondary sealing strip is clamped on the outer edge of the cover plate to form a double-layer sealed top cover. An Ω-shaped overlapping cover plate is provided between two adjacent top covers, and the cover plate is connected to the top cover through a groove structure to form an outer package structure. A handle is provided on the top cover, and the top cover structure is also equipped with a top cover locking rod. When locked, the top cover locking rod presses the top cover tightly onto the container body.

[0034] Double-layer sealing method: A double-layer sealing method is set on the small top cover. The double-layer sealing can further enhance the sealing after the top cover is closed, effectively preventing external impurities such as rainwater and dust from entering the box, and protecting the goods from contamination.

[0035] Embodiment 3: A discharge port is provided at the bottom of the container body, and a discharge plate is provided at the discharge port to cover the discharge port. The discharge plate is slidably connected to the discharge port, and the discharge port is opened or closed by pulling. A handle and a lock box are provided on the discharge plate, and a lock nose is provided in the lock box. When the discharge plate is in a state of closing the discharge port, the lock nose is exposed outside the discharge plate, and is used to lock the discharge plate to the container body.

[0036] A positioning angle steel is provided above the discharge port, which is fixedly connected to the container body. The positioning angle steel is used as a guide component to guide the movement of the discharge plate. The positioning angle steel is also used to waterproof the top of the discharge port. At least two track round steels are installed at the bottom of the discharge port, and each track round steel is provided with a track wheel to ensure the smooth movement of the discharge plate; the positioning angle steel and the track round steel form a sliding track to support the discharge plate. A discharge baffle is provided on the container body. After the discharge plate is opened to the maximum limit, the discharge baffle prevents the discharge plate from continuing to move to avoid excessive opening.

[0037] Pull-out discharge mechanism. Through the pull-out action, the discharge port can be quickly opened or closed to control the outflow of materials. This mechanism is not only easy to operate, but also can quickly respond to the discharge demand and ensure the discharge speed. Because the structure of the discharge port uses materials that are easy to process and assemble, while avoiding complex mechanical parts and transmission systems, the overall cost is reduced.

[0038] Embodiment 4: A guide plate is fixedly connected to the inner wall of the container box to guide the material flow path and avoid material accumulation or dead corners. The guide plate can be set at the four corners of the bottom of the box, and the guide plate has an inclination angle that facilitates the flow of materials. The design of the discharge port takes into account the type of cargo, including the particle size, density, fluidity, etc. of the material. According to these characteristics, the size, shape and design of the guide plate of the discharge port can be adjusted to ensure that the material can flow out smoothly. And add a guide plate in the box to guide the material to flow along a predetermined path to avoid material accumulation or dead corners in the box. By reasonably designing the shape and angle of the guide plate, the unloading efficiency can be significantly improved and the material residue can be reduced.

[0039] Specifically, in the technical solution:

[0040] 1. Overall structure.

[0041] Based on the standard 20-foot container, the door end is adjusted to the front end structure, and a pull-out discharge port and a safe and stable ladder are specially added for easy operation. The top plate is adjusted to a top-opening door structure with overlapping opening, and the top cover structure is double-sealed. A guide plate is added inside the box to prevent materials from piling up or forming dead corners.

[0042] 2. Top cover structure.

[0043] 1) The top plate and lip structure are spliced ​​into an integral opening structure using the patterned plate integral bending process, and overlapping gaps are cleverly set at the overlapping position of the top cover to ensure the tightness of the structure.

[0044] 2) The top cover is divided into five sets of three types, and different numbers of top covers can be flexibly opened according to actual needs to meet different loading needs. The top cover plate is designed as a box-type structure, and a top cover reinforcement groove is added. The top cover sealing strip is embedded in the groove, and the secondary sealing strip is clamped on the outer edge of the cover plate to further improve the sealing performance. An Ω-shaped overlapping cover plate is provided between two adjacent top covers, which can not only ensure the sealing of the overlapping position, but also enhance the stability of the structure. The interface position of the Ω-shaped overlapping cover plate is a groove structure, which naturally forms an outsourcing structure after overlapping, and is additionally equipped with waterproof round steel, thereby fully guaranteeing the waterproof sealing performance of the interface.

[0045] 3) The top cover is also equipped with a top cover handle, which can press the top cover tightly through the top door lock rod to ensure the sealing of the top cover, effectively prevent rainwater, dust and other external impurities from invading the box, and protect the goods from pollution in all directions.

[0046] 3. Discharge port structure.

[0047] 1) The unloading plate adopts a thick plate structure, which ensures the stability and durability of the overall structure. We specially set up a handle and a lock box at the unloading plate position. When the lock box is closed, it can effectively limit the position and firmly lock the unloading plate through the lock nose to ensure safety and stability.

[0048] 2) A positioning angle steel is provided above the discharge port (which serves as a guide and waterproof function on the top), and multiple track round steels and track wheels are provided at the lower port to make the opening and closing process of the discharge plate smoother.

[0049] 3) When opening, a discharge baffle (limiting function) is provided, which can effectively prevent the discharge plate from moving further when it reaches the maximum opening angle, thereby avoiding damage or safety hazards that may be caused by excessive opening.
