[0069] Now, reference will be made to the attached Figures 1 to 6 A more detailed description of the exemplary embodiments according to the present utility model will be given.

[0070] The present utility model provides a self-unloading container 100, as Figure 1 and Figure 2As shown, the self-unloading container 100 includes a chassis 10, a telescopic lifting device 20, and a box body 30. The chassis 10 includes a first end 11 and a second end 12 opposite to each other in the length direction D1. One end of the telescopic lifting device 20 is pivotally connected to the first end 11 of the chassis 10. The box body 30 is located above the chassis 10 and includes a front end 31 and a rear end 32 opposite to each other in the length direction D1, and the front end 31 is located in front of the rear end 32. The rear end 32 is pivotally connected to the second end 12, for example, by connecting a bushing welded to the chassis 10 and a pin welded to the box body 30. The front end 31 includes a first front plate 311, a second front plate 312, and a connecting plate 313.

[0071] Wherein, the first front plate 311 and the second front plate 312 are arranged at intervals, and the first front plate 311 is located in front of the second front plate 312. The dimension of the second front plate 312 in the width direction D2 of the chassis 10 is smaller than the dimension of the box body 30 in the width direction D2. The lower end of the second front plate 312 is connected to the bottom 33 of the box body 30. The connecting plate 313 is used to connect the first front plate 311 and the second front plate 312. The bottom 33 of the box body 30 has a notch in front of the second front plate 312, and the other end of the telescopic lifting device 20 is pivotally connected to the second front plate 312 through the notch.

[0072] It should be noted that the first front plate 311 is located on the front end face of the box body 30. The first front plate 311 can be an entire plate connected to the top 34, the bottom 33, and two front corner posts 315 of the box body 30, that is, the first front plate 311 includes an extended portion at a position directly opposite in front of the second front plate 312, which can protect the connection end of the telescopic lifting device 20 and the box body 30. The first front plate 311 can also extend partially in the width direction D2. For example, the first front plate 311 includes two parts in the width direction D2, which are respectively connected to the two front corner posts 315, that is, the first front plate 311 does not extend to the position directly opposite in front of the second front plate 312, and the connection end of the telescopic lifting device 20 and the box body 30 is exposed. The connecting plate 313 can be one or more. The connecting plate 313 can be arranged parallel to the length direction D1, or can be arranged at an angle to the length direction D1. For example, the cross-sections of the first front plate 311, the second front plate 312, and the connecting plate 313 in the horizontal direction form a trapezoid, and the cross-section of the connecting plate 313 is the waist of the trapezoid.

[0073] It can be understood that the bottom 33 of the box body 30 has a notch in front of the second front plate 312. This notch creates a receiving space in front of the second front plate 312 of the box body 30 for receiving the connection end of the telescopic lifting device 20 to the box body 30. That is, the telescopic lifting device 20 can extend to the front of the second front plate 312 but does not penetrate into the interior of the box body 30. At the same time, during the pivoting process of the box body 30, the bottom 33 does not interfere with the telescopic lifting device 20. The connecting plate 313, the second front plate 312 and the first front plate 311 of the box body 30 are connected. The connecting plate 313 and the second front plate 312 form a part of the wall of the storage space inside the box body 30, and at least a part of the first front plate 311 forms a part of the wall of the storage space inside the box body 30. The size of the second front plate 312 in the width direction D2 is set such that there is sufficient space in front of the second front plate 312 to accommodate the connection end of the telescopic lifting device 20 to the box body 30. At the same time, the size of the second front plate 312 in the width direction D2 is smaller than the width of the box body 30. Therefore, there is still space for accommodating goods between the connecting plate 313 and the side plate 35 of the box body 30, so that the space utilization rate inside the box body 30 is high, and the cargo loading capacity of the self-unloading container 100 is improved.

[0074] The top 34 of the box body 30 can extend to the second front plate 312 or the front end face of the box body 30 in the length direction D1. As Figure 2 and Figure 3 shown, the top 34 of the box body 30 extends to the front end face of the box body 30, which can provide protection such as rain shielding for the telescopic lifting device 20. For the convenience of loading and unloading goods, as Figure 2 shown, the top 34 of the box body 30 can be provided with an opening 341. Further, the opening 341 can also be set to extend throughout in the length direction D1.

[0075] As Figures 1 to 3 shown, to ensure the structural strength of the front end 31 of the box body 30, the front end 31 further includes a vertical beam 314. The vertical beam 314 is connected to the top 34 and the bottom 33 of the box body 30 along the height direction D3 of the box body 30. The connecting plate 313 and the first front plate 311 are connected to the vertical beam 314, and the connecting plate 313 and the second front plate 312 are connected to the vertical beam 314. That is, there can be multiple vertical beams 314, and the vertical beams 314 are spaced apart from the side plate 35 of the box body 30. For example, the vertical beam 314 is located at the connection between the second front plate 312 and the connecting plate 313, or at the connection between the first front plate 311 and the connecting plate 313 on the front end face of the box body 30.

[0076] Optionally, the first front plate 311, the connecting plate 313 and the second front plate 312 are all connected to the top 34 and the bottom 33 of the box body 30 along the height direction D3 of the box body 30.

[0077] Optionally, the second front panel 312 is smaller than the box body 30 in size in the height direction D3. That is, the lower end of the second front panel 312 is connected to the bottom of the box body 30, the upper end is not connected to the top 34 of the box body 30, and the upper end is connected to the first front panel 311 through a connecting plate 313.

[0078] Preferably, the length of the second front panel 312 to the rear end 32 is greater than or equal to the length of a 20-foot standard container. That is, the box body 30 is a box body obtained by extending the front end or both the front end and the rear end of a 20-foot standard container, so as to increase the cargo loading capacity of the box body 30.

[0079] As Figure 3 As shown, a hinge bracket 36 extending forward in the length direction D1 is fixed to the second front panel 312, and the second front panel 312 is hinged to the telescopic lifting device 20 through the hinge bracket 36. In a specific embodiment, the hinge bracket 36 includes a vertical plate 361 and two hinge plates 362. The vertical plate 361 is fixedly attached to the second front panel 312. The two hinge plates 362 are spaced apart in the width direction D2 of the chassis 10 and extend forward in the length direction D1. One end of the hinge plate 362 is fixedly connected to the vertical plate 361, and the other end of the hinge plate 362 has a hinge hole. A connecting shaft 21 on the telescopic lifting device 20 passes through the hinge hole and is pivotally connected to the hinge plate 362. Thus, the telescopic lifting device 20 will not interfere with the second front panel 312 during the process of supporting the pivoting of the box body 30.

[0080] Optionally, the telescopic lifting device 20 is a hydraulic cylinder, and devices such as an oil tank and oil pipes that cooperate with the hydraulic cylinder are also provided on the chassis 10. Of course, the telescopic lifting device 20 can also be other acting devices that can be telescoped to lift one end of the box body 30 to make it pivot.

[0081] As Figure 1 As shown, the pivoting angle θ of the box body 30 supported by the telescopic lifting device 20 is less than or equal to 45°. When the box body 30 pivots to 45°, it can ensure complete unloading of the bulk goods in the box body 30, and the unloading efficiency is high.

[0082] In order to make the box body 30 more stable during the pivoting process and avoid side deviation, the front end 31 can be symmetrically arranged in the width direction D2, and the hinge bracket 36 is located at the middle position of the second front panel 312 in the width direction D2.

[0083] To further stabilize the pivoting of the box body 30, a balance frame 14 is provided in the middle of the chassis 10 in the length direction D1. The balance frame 14 includes a first connecting portion 141 and a second connecting portion 142. The chassis 10 is pivotally connected to the first connecting portion 141, the first connecting portion 141 is pivotally connected to the second connecting portion 142, and the second connecting portion 142 is pivotally connected to the bottom 33 of the box body 30. Both the first connecting portion 141 and the second connecting portion 142 include two connecting columns 143 that are spaced apart and connected along the width direction D2 of the chassis 10, for example, in an H shape or a ladder shape. Thus, during the pivoting of the box body 30, the balance frame 14 keeps the box body 30 balanced in the width direction D2. When the box body 30 falls back to the chassis 10, the balance frame 14 folds through the pivoting between the first connecting portion 141 and the second connecting portion 142 and retracts into the chassis 10 without interfering with the box body 30 in the height direction D3.

[0084] When the box body 30 falls back to the chassis 10, as Figures 3 to 5 shown, guide plates 15 can be respectively provided on both sides of the chassis 10 in the width direction D2 to guide and position the box body 30 in the width direction D2. Specifically, the lower end of the guide plate 15 is fixedly connected to the outer side of the side beam of the chassis 10, and the upper end of the guide plate 15 is inclined away from the chassis 10.

[0085] In addition, the chassis 10 can include bottom corner fittings 13. For example, one bottom corner fitting 13 is respectively provided at the four corners of the chassis 10. Therefore, the self-unloading container 100 can be conveniently installed on an ordinary semi-trailer without a lifting device and has a self-unloading function, with flexible and wide applications.

[0086] The chassis 10 can also include an automatic locking device 16 for automatically locking the box body 30 after the box body 30 falls back to the chassis 10, fixing the box body 30 to the chassis 10, and automatically unlocking when the box body 30 is about to pivot.

[0087] As Figure 6 shown, a door body 321 is provided at the rear end 32 of the box body 30. During unloading, the door body 321 can be opened, and as the box body 30 pivots, the bulk goods in the box can pour out of the box from the rear end 32.

[0088] Unless otherwise defined, the technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the technical field of the present utility model. The terms used herein are only for the purpose of describing specific implementation purposes and are not intended to limit the present utility model. The features described in one embodiment herein can be applied alone or in combination with other features to another embodiment, unless the feature is not applicable or otherwise stated in that other embodiment.

[0089] The present utility model has been described through the above embodiments. However, it should be understood that the above embodiments are only for illustrative and explanatory purposes. The present utility model is not limited to the above embodiments, and more variations and modifications can be made according to the teachings of the present utility model, and these variations and modifications all fall within the scope of protection required by the present utility model.
