[0028] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0029] like Figures 1 to 3 As shown, this embodiment provides a powder and granular material transportation tank body, including a tank body 1 and an air bag 2.

[0030] In this embodiment, the tank body 1 is a straight cylindrical structure to maximize the volume utilization of the tank body 1; and the tank body 1 is a single-bin structure, and the unloading operation steps are more convenient.

[0031] For example, the cross section of the tank body 1 may be circular, elliptical, rectangular, etc.

[0032] In this embodiment, the material of the airbag 2 is specially customized high temperature resistant and wear resistant rubber. The powder and granular material transport tank also includes an inflation valve c connected to the airbag 2, and the inflation valve c is used to control the inflation and exhaust of the airbag 2.

[0033] Combination Figure 1 As shown, a discharge hole 101 is provided at the bottom of the tank body 1, and the discharge hole 101 connects the inside of the tank body 1 with the outside of the tank body 1; the airbag 2 is located in the tank body 1 and is spaced apart from the discharge hole 101; the fixed end a of the airbag 2 close to the discharge hole 101 is fixed to the tank body 1, and the movable end b of the airbag 2 is movably arranged relative to the tank body 1, and the movable end b of the airbag 2 can adjust the angle of the airbag 2 relative to the tank body 1 when it is raised or lowered along the height direction of the tank body 1.

[0034] In this embodiment, the fixed end a of the airbag 2 close to the discharge hole 101 is fixed in the tank body 1, and the movable end b of the airbag 2 is movably arranged relative to the tank body 1. The movable end b of the airbag 2 can be lifted and lowered along the height direction of the tank body 1. By tilting the airbag 2, the powder and granular materials in the tank body 1 are lifted, and the discharge speed of the powder and granular materials is accelerated, which is conducive to the discharge of the powder and granular materials from the tank body 1. In addition, the airbag 2 can be raised or lowered according to the repose angle of different powder and granular materials in the tank body 1 to adjust the tilt angle of the airbag 2 relative to the tank body 1, so that the tank body 1 can transport different powder and granular materials, and realize the versatility of the tank body 1 in transporting powder and granular materials.

[0035] It should be understood that the angle of repose refers to the maximum angle at which the powder and granular materials maintain a natural stable state relative to the ground when stacked. The airbag 2 is spaced apart from the discharge hole 101 to ensure that the airbag 2 does not cover the discharge hole 101 and affect the discharge of the tank body 1. The fixed end a of the airbag 2 and the movable end b of the airbag 2 are the two ends of the airbag 2 along the axial direction of the tank body 1, the fixed end a of the airbag 2 is the end close to the discharge hole 101, and the movable end b of the airbag 2 is the end away from the discharge hole 101.

[0036] Combination Figure 1 As shown, the discharge hole 101 is located at the middle part 12 of the tank body 1 along the axial direction of the tank body 1, and the airbag 2 includes a first airbag part 21 and a second airbag part 22. The fixed end a of the first airbag part 21 close to the discharge hole 101 is fixed to the tank body 1, and the movable end b of the first airbag part 21 is extended toward the front part 11 of the tank body 1, and can be lifted and lowered along the height direction of the tank body 1; the fixed end a of the second airbag part 22 close to the discharge hole 101 is fixed to the tank body 1, and the movable end b of the second airbag part 22 is extended toward the rear part 13 of the tank body 1, and can be lifted and lowered along the height direction of the tank body 1.

[0037] In this embodiment, since the first airbag portion 21 and the second airbag portion 22 are respectively located at the two ends of the discharge hole 101 along the axial direction of the tank body 1, when the movable ends b of the first airbag portion 21 and the second airbag portion 22 rise, the first airbag portion 21 and the second airbag portion 22 are both inclined relative to the tank body 1, and the shapes of the first airbag portion 21 and the second airbag portion 22 are approximately "funnel". The movable ends b of the first airbag portion 21 and the second airbag portion 22 lift the powder and granular materials in the tank body 1, so that the powder and granular materials in the tank body 1 are inclined, thereby accelerating the discharge speed of the powder and granular materials and reducing the unloading time of the tank body 1.

[0038] It should be understood that the tank body 1 is divided into three parts along the axial direction of the tank body 1, that is, the tank body 1 includes a front part 11, a middle part 12 and a rear part 13. The middle part 12 is located in the middle position of the tank body 1, the front part 11 is a part of the middle part 12 close to the front of the vehicle, and the rear part 13 is a part of the middle part 12 close to the rear of the vehicle.

[0039] In this embodiment, the discharge hole 101 is located in the middle part 12 of the tank body 1 along the axial direction of the tank body 1, so that the fixed ends a of the first airbag part 21 and the second airbag part 22 are both located in the middle part 12 of the tank body 1, the movable end b of the first airbag part 21 is located at the front part 11 of the tank body 1, and the movable end b of the second airbag part 22 is located at the rear part 13 of the tank body 1, so that the powder and granular materials located at both ends of the discharge hole 101 can be lifted by the airbag 2, thereby accelerating the discharge speed of the powder and granular materials.

[0040] Preferably, the discharge hole 101 is located at the center of the middle portion 12 , which is conducive to the discharge of the powder and granular materials in the tank body 1 .

[0041] In other embodiments, in combination Figure 4 As shown, the discharge hole 101 is located between the middle portion 12 of the tank body 1 and the rear portion 13 of the tank body 1 along the axial direction of the tank body 1 .

[0042] Preferably, the discharge hole 101 is located at the rear portion 13 of the tank body 1 , and other components are arranged at the rear portion 13 of the tank body 1 with fewer components, so that the powder and granular materials in the tank body 1 can be easily discharged.

[0043] It should be understood that the discharge hole 101 of most powder and particle material transport tanks is located in the middle part 12 of the tank 1 or the rear part 13 of the tank 1 to facilitate the discharge of the powder and particle materials in the tank 1. However, the position of the discharge hole 101 can be selected according to factors such as the use scenario of the powder and particle material transport tank and the specific structure of the powder and particle material transport tank.

[0044] Combination Figure 1 and Figure 2 As shown, the powder and granular material transport tank body further includes a fixing member 3 , and the airbag 2 is connected to the tank body 1 via the fixing member 3 .

[0045] In this embodiment, the fixing member 3 is a rectangular structure, and the fixing member 3 is connected to the airbag 2 along the axial direction of the tank body 1 by bolts or adhesion. The fixing member 3 can be used to fix the airbag 2 and also has the function of limiting the extension of the airbag 2.

[0046] It should be understood that during the lifting and lowering process of the movable end b of the airbag 2, the fixing member 3 can allow the airbag 2 between the movable end b and the fixed end a to lift and lower along with the movable end b, so that the angle value between the entire airbag 2 and the tank body 1 remains consistent, so as to facilitate the discharge of powder and granular materials from the tank body 1.

[0047] Combination Figure 1 and Figure 2As shown, the fixing member 3 includes a plurality of fixing portions 31, and the plurality of fixing portions 31 are sequentially arranged along the axial direction of the tank body 1, and the airbag 2 is connected to the tank body 1 through the fixing portion 31 closest to the discharge hole 101 among the plurality of fixing portions 31; two adjacent fixing portions 31 among the plurality of fixing portions 31 are hinged so that the fixing portion 31 can rotate toward the top or bottom of the tank body 1.

[0048] In this embodiment, the fixed end a of the airbag 2 is connected to the tank body 1 through the fixed portion 31 closest to the discharge hole 101 among the multiple fixed portions 31, so as to ensure that the fixed end a of the airbag 2 is fixed to the position of the tank body 1 close to the discharge hole 101. The powder and granular material transport tank body also includes a hinge d, and two adjacent fixed portions 31 among the multiple fixed portions 31 are hinged by the hinge d, so that the airbag 2 can be folded at a certain angle at the position between the two adjacent fixed portions 31, so as to prevent the airbag 2 from interfering with the tank body 1 and affecting the lifting and lowering of the airbag 2.

[0049] Combination Figure 2 As shown, the powder and granular material transport tank body comprises a plurality of fixing members 3, and the plurality of fixing members 3 are arranged at intervals from each other along the radial direction of the tank body 1.

[0050] In this embodiment, the powder and particle material transport tank body includes seven fixing parts 3, which are laid flat on one side of the airbag 2 close to the top of the tank body 1 along the axial direction of the tank body 1 and are spaced apart from each other along the radial direction of the tank body 1 to limit the extension of the airbag 2.

[0051] Combination Figure 1 As shown, the powder and particle material transport tank body further includes an angle sensing chip 4 for detecting the real-time angle of the airbag 2 ; the angle sensing chip 4 is connected to the airbag 2 and is located inside the tank body 1 .

[0052] In this embodiment, the powder and particle material transport tank also includes a control box e for controlling the lifting and lowering of the airbag 2. The angle sensing chip 4 is connected to the side of the airbag 2 close to the bottom of the tank 1. The angle sensing chip 4 moves up and down with the lifting and lowering of the airbag 2, and detects the real-time angle between the airbag 2 and the tank 1, and feeds back the signal of the relevant angle value to the control box e.

[0053] It should be understood that since different powder and granular materials have different repose angles when they slide down, the airbag 2 can be set to different lifting and lowering gears according to different powder and granular materials. The angle sensing chip 4 will feed back the real-time angle data of the lifting and lowering of the airbag 2 to the control box e, and the control box e will control the lifting and lowering of the airbag 2.

[0054] In this embodiment, the lifting and lowering of the airbag 2 has three different gears, and different gears can be selected for different powder and granular materials to achieve the versatility of powder and granular material transportation.

[0055] Combination Figure 1As shown, the powder and particle material transport tank body also includes a discharge pipe 5, one end of which is connected to the hole wall of the discharge hole 101 and communicates with the tank body 1 through the discharge hole 101; the other end of the discharge pipe 5 is connected to the outside of the tank body 1; the powder and particle material transport tank body also includes a discharge valve 6, which is connected to the discharge pipe 5 to control the connection and disconnection between the discharge pipe 5 and the tank body 1.

[0056] In this embodiment, the discharge pipe 5 is passed through the discharge hole 101 and connected to the hole wall of the discharge hole 101, connecting the inside of the tank body 1 with the outside of the tank body 1 to discharge the powder and granular materials in the tank body 1. The discharge valve 6 is used to control the connection and disconnection between the discharge pipe 5 and the inside of the tank body 1. When the discharge valve 6 is opened, the discharge pipe 5 is connected to the inside of the tank body 1, and the powder and granular materials in the tank body 1 are transported to the outside of the tank body 1; when the discharge valve 6 is closed, the discharge pipe 5 is not connected to the inside of the tank body 1, and the powder and granular materials in the tank body 1 cannot be transported to the outside of the tank body 1.

[0057] Combination Figure 1 As shown, the powder and particle material transport tank body further includes a first air inlet pipeline 7 and a second air inlet pipeline 8 , wherein the first air inlet pipeline 7 is connected to the airbag 2 ; and the second air inlet pipeline 8 is connected to the inside of the tank body 1 .

[0058] In this embodiment, the first air inlet pipeline 7 is connected to the airbag 2 through the inflation valve c to deliver compressed gas to the airbag 2. The bottom of the tank body 1 is also provided with an air inlet hole 102, and the air inlet hole 102 and the discharge hole 101 are arranged at intervals from each other. One end of the second air inlet pipeline 8 is passed through the air inlet hole 102 and connected to the hole wall of the air inlet hole 102. The second air inlet pipeline 8 is connected to the tank body 1 through the air inlet hole 102 to deliver compressed gas to the tank body 1.

[0059] Furthermore, one end of the inflation valve c is connected to the first air inlet pipeline 7 to deliver compressed gas to the airbag 2 ; the other end of the inflation valve c is used to discharge the compressed gas in the airbag 2 .

[0060] In this embodiment, combined with Figure 1 As shown, the powder and particle material transport tank also includes a one-way valve f and a safety accessory g. The one-way valve f is connected to the first air inlet pipeline 7 and the second air inlet pipeline 8, so that the compressed gas is transported in one direction to prevent the compressed gas from flowing back. The safety accessory g is connected to the first air inlet pipeline 7 and the second air inlet pipeline 8 to ensure the safety of the tank body 1 and avoid excessive pressure in the tank body 1.

[0061] This embodiment further provides a vehicle, comprising an air source device and the above-mentioned powder and particle material transport tank body, wherein the air source device is connected to the tank body 1 and the airbag 2 .

[0062] In this embodiment, the air source device is connected to the airbag 2 through the first air inlet pipeline 7 to deliver compressed gas to the airbag 2; the air source device is connected to the tank body 1 through the second air inlet pipeline 8 to deliver compressed gas to the tank body 1.

[0063] It should be understood that the powder and particle material transport tank lifts the powder and particle material in the tank body 1 through the airbag 2, which not only makes it unnecessary for the vehicle to lift the tank body 1 through the hydraulic lifting system to discharge the powder and particle material in the tank body 1, thus saving investment costs; it also keeps the center of gravity of the entire vehicle at a lower position, making it less likely for the vehicle to tip over during operation, thereby reducing the requirements for the site and weather during operation of the vehicle, thereby improving the safety and frequency of use of the vehicle.

[0064] In summary, after the control box e selects the gear position for raising and lowering the airbag 2 according to the powder and granular material in the tank body 1, the compressed gas is delivered to the tank body 1 and the airbag 2 through the air source device, and the compressed gas passes through the one-way valve f, the first air inlet pipeline 7 and the inflation valve c to deliver the compressed gas to the airbag 2. At the same time, the compressed gas passes through the one-way valve f and the second air inlet pipeline 8 to deliver the compressed gas to the tank body 1; with the input of compressed gas, the air pressure in the tank body 1 slowly increases, and the airbag 2 is slowly raised synchronously. Under the limitation of the fixing part 3, the active end b of the airbag 2 rises, and the angle between the airbag 2 and the tank body 1 slowly increases. After the unloading valve 6 is opened, the unloading pipe 5 starts to unload; the angle sensing chip 4 will feed back the real-time angle data to the control box e. When the airbag 2 reaches the preset gear position, the inflation valve c is closed and the inflation into the airbag 2 stops; after the unloading is completed, the inflation valve c is opened and the airbag 2 starts to exhaust.
