[0043] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0044] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0045] The present invention provides a tanker truck, which is used for transporting powdery materials, such as chemical powdery and granular materials and food powdery and granular materials.

[0046] The tank truck includes a frame and a tank body mounted on the frame. For ease of description, the length direction of the frame is defined as the longitudinal direction, the width direction is defined as the transverse direction, the direction close to the tank truck's forward direction is defined as the front direction, and the direction opposite to the front direction is defined as the rear direction. The axial direction of the tank body extends in the longitudinal direction.

[0047] In the present application, the volume of the tank body is relatively large, thereby increasing the single transport volume of the tank truck. The tank body is described in detail below.

[0048] Embodiment 1

[0049] The tank is used to load materials. Figure 1 Schematic diagram of the structure of the tank in this embodiment is shown. Figure 2 shows the front view of the tank, Figure 3 A top view of the tank is shown. Figure 4 shows a side view of the tank, combined with Figure 1-Figure 4 The tank body 1 includes at least two cylinder sections arranged axially and connected end to end, and a reinforcing ring 14 arranged between two adjacent cylinder sections.

[0050] In this embodiment, the number of cylinder segments is two, and correspondingly, the number of reinforcement ring 14 is one.

[0051] Each cylinder section includes an upper cylinder 11 and a lower cone 12 disposed below the upper cylinder 11. The cross section of the upper cylinder 11 is semi-elliptical. The left-right diameter of the upper cylinder 11 is greater than its up-down diameter. In this application, the left-right direction refers to the horizontal direction, and the up-down direction refers to the vertical direction. That is, the long axis of the upper cylinder 11 extends in the horizontal direction. Compared with the circular structure, the semi-elliptical shape has a wider width, thereby increasing the volume of the entire tank body 1.

[0052] A manhole is provided at the top of the upper cylinder 11 for loading materials into the tank 1. A manhole cover is also provided at the manhole.

[0053] The lower cone 12 is disposed below the upper cylinder 11. Specifically, the lower cone 12 is in a flat cone shape, the lower cone 12 gradually expands in diameter from bottom to top, and the left-right width of the lower cone 12 at each horizontal section is not greater than the front-back width.

[0054] A discharge hole is provided at the bottom of the lower cone 12 for unloading the material in the tank.

[0055] Compared with the traditional tank body, the lower cone 12 in this embodiment accounts for a larger proportion of the total height of the tank body 1, which not only ensures that the volume of the entire tank body 1 is larger, but also the lower cones 12 of the two cylinder sections can unload at the same time, thereby improving the unloading speed.

[0056] Among the two cylinder sections, the bottom of the lower cone 12 of the cylinder section located in the front extends downward beyond the bottom of the lower cone 12 of the cylinder section located in the rear.

[0057] The tank body 1 further comprises end caps 13 arranged at both ends of the axial direction. The cross section of each end cap 13 is elliptical. In the present application, the elliptical shape of the end cap 13 can be a standard ellipse or an approximate ellipse with a major axis and a minor axis.

[0058] In the present application, an elliptical or circular opening is provided at the bottom of the lower cone 12, and a conical fluidizing cone 15 is provided at the opening. The upper cross section of the fluidizing cone 15 is adapted to the bottom opening of the lower cone 12, and is elliptical or circular, and the lower cross section is circular. A circular discharge hole is provided at the bottom center of the fluidizing cone 15. It should be noted that the ellipse in the present application can be either a standard ellipse or an approximate ellipse with a major axis and a minor axis, and the circle in the present application can be either a standard circle or an approximate circle with a certain tolerance.

[0059] The reinforcement ring 14 is a closed annular ring, surrounding the outer circumference of the cylinder section to increase the strength of the entire tank body 1.

[0060] Figure 5 and Figure 6 The structural schematic diagrams of the reinforcement ring 14 in different directions are shown respectively. Figure 7 A schematic diagram showing the connection between the reinforcement ring 14 and the cylinder section is shown. Figure 5 , Figure 6 and Figure 7 The radial cross section of the reinforcing ring 14 is T-shaped. The reinforcing ring 14 includes an outer ring 141 and a connecting ring 142 located on the inner periphery of the outer ring 141. The connecting ring 142 extends radially along the outer ring 141, and the outer ring 141 protrudes the connecting ring 142 in the front and rear directions respectively to form two connecting parts 1411. The connecting ring 142 extends between two adjacent cylinder sections and is respectively connected to the two adjacent cylinder sections. The outer ring 141 is exposed outside the cylinder section, and the two connecting parts 1411 are respectively connected to the outer walls of the two adjacent cylinder sections.

[0061] Figure 8 A schematic diagram showing the connection between the reinforcing ring 14 and the upper cylinder 11 is shown. Figure 8 When the reinforcing ring 14 is connected to the cylinder segment, the connecting portion 1411 of the outer ring 141 is attached to the outer wall of the upper cylinder 11 and fixedly connected, and the connecting ring 142 is fixedly connected to the end surface of the upper cylinder 11.

[0062] Fig. 9 A schematic diagram showing the connection between the reinforcing ring 14 and the lower cone 12 is shown. Fig. 9 The connecting parts 1411 of the two outer rings 141 respectively abut against the outer walls of the two lower cones 12, the opposite side surfaces of the connecting ring 142 respectively abut against the end surfaces of the two lower cones 12, and the bottoms of the two lower cones 12 and the connecting ring 142 together enclose a closed triangular area.

[0063] The reinforcing ring 14 can be integrally formed, or can be obtained by welding the outer ring 141 and the connecting ring 142. Further, the outer ring 141 includes two ring bodies, which are respectively welded to opposite sides of the connecting ring 142.

[0064] Fig.10 A schematic cross-sectional view of the tank body 1 along the EE direction is shown. Fig. 9 A reinforcing rib 16 is provided inside the cylinder section to further increase the strength of the cylinder section.

[0065] Fig.11 FIG. 1 shows a schematic diagram of the reinforcing ribs in the tank body in this embodiment, see FIG. Fig.11 , two reinforcing ribs 16 are provided in each cylinder section along the axial direction. In other embodiments, the number of reinforcing ribs 16 can be set according to actual needs, such as one or three. And the number of reinforcing ribs 16 in multiple cylinder sections in the same tank body 1 can be equal or unequal.

[0066] Specifically, the two reinforcing ribs 16 in the same cylinder section are arranged at the front and rear ends of the discharge hole at the bottom of the cylinder section and are located above the fluidizing cone 15 at the bottom of the cylinder section. In other embodiments, the position of the reinforcing ribs 16 in the cylinder section can be set according to actual needs.

[0067] Fig.12 A schematic structural diagram of the reinforcing rib 16 is shown, see 12 , the reinforcing rib 16 comprises a reinforcing ring 161 and at least three radially distributed supporting members 162 connected to the reinforcing ring 161 .

[0068] The reinforcing ring 161 is connected to the inner wall of the cylinder section and protrudes from the inner wall, one end of all the supporting members 162 intersects at one point in the cylinder section, and the other end of each supporting member 162 is spaced apart on the reinforcing ring 161. The reinforcing ring 161 is in a non-closed arc shape, and its bottom is broken to form a material flow port.

[0069] In this embodiment, the end surface of the bottom of the reinforcement ring 161 is an inclined surface, and the inclined surfaces of the two end surfaces make the reinforcement ring 161 gradually close from top to bottom, that is, the diameter of the flow port gradually decreases from top to bottom. This structural design allows the material to flow to the discharge hole better along the inner wall of the reinforcement ring 161 and the inclined surface of the end.

[0070] The reinforcement ring 161 and the support members 162 are integrally formed, wherein one support member 162 extends vertically and is located on the transverse center axis of the cylinder section, and the other support members 162 are symmetrically distributed relative to the transverse center axis.

[0071] In this embodiment, there are three support members 162. Further, the three support members 162 are in an inverted Y shape.

[0072] In other embodiments, the number of the support members 162 may be four, five or other numbers. For example, when there are four support members, the four support members are distributed in an X pattern. When there are five support members, one of the support members is located on the transverse center axis of the cylinder section, and the remaining four support members are symmetrically distributed about the transverse center axis.

[0073] Specifically, the support member 162 includes a main body 1621 and an extension portion 1622 disposed at one end of the main body 1621. The main body 1621 is linear, and the size of the extension portion 1622 gradually increases in a direction away from the main body 1621. The extension portion 1622 is connected to the reinforcement ring 161. The strength of the support member 162 and the strength of the connection between the support member 162 and the reinforcement ring 161 are increased by increasing the size of the extension portion 1622.

[0074] The tank body in this embodiment includes two cylinder sections arranged in the axial direction and connected end to end. When the two cylinder sections are assembled to form the tank body, the reinforcing ring 14 plays a role in positioning the two cylinder sections. When the cylinder sections are welded, the reinforcing ring 14 also plays a role in fixing and supporting the cylinder sections, which is convenient for welding, making the welding process between the two cylinder sections simple, thereby simplifying the manufacturing process of the tank body 1. The reinforcing ring 14 also improves the strength of the entire tank body 1.

[0075] The reinforcing ring 14 is welded to the two cylinder sections respectively, and the weld between the reinforcing ring 14 and the cylinder section is a circumferential weld, which improves the universality of the production process standard, is conducive to mechanized automatic welding, improves the production efficiency of the tank body 1, and effectively improves the product welding quality, thereby improving the overall product quality.

[0076] Each cylinder section includes an upper cylinder 11 with a semi-elliptical cross section and a lower cone 12 disposed below the upper cylinder 11. The semi-elliptical upper cylinder 11 widens the width of the upper portion of the entire tank body 1, thereby increasing the volume of the entire tank body 1, that is, increasing the effective loading capacity of the tank body 1, thereby increasing the single transport capacity of the tank truck. At the same time, the lower cone 12 at the lower portion of the tank body 1 adopts a flat cone design, and compared with the traditional tank body 1, the cone portion of the present invention occupies a larger proportion, while increasing the effective loading capacity, increasing the inclination of the lower portion of the tank body 1, so that the material slides smoothly to the bottom, which is more conducive to unloading.

[0077] Compared with the solution of connecting the cylinder and the cone through multiple connecting plates in the related art, due to the complex structure of the connecting plates in the related art, the effective space for loading materials inside the tank is limited and the self-weight is heavy. The tank body 1 in this embodiment increases the volume of the tank body through the structure of the semi-elliptical upper cylinder 11 and the flat cone-shaped lower cone 12. In addition, the strength of the tank body is increased by the reinforcement ring 14 and the reinforcement rib 16. The reinforcement ring 14 and the reinforcement rib 16 have a simple structure and light weight, which effectively improves the volume utilization of the tank body while reducing the overall self-weight of the tank body.

[0078] Embodiment 2

[0079] See also Figure 13-Figure 15 The difference between this embodiment and the first embodiment is that the reinforcing rib 26 in this embodiment includes a reinforcing ring 261 and three reinforcing rods 262 connected to the reinforcing ring 261. The reinforcing ring 261 is connected to the inner side wall of the cylinder section and protrudes from the inner side wall. The reinforcing ring 261 is in a non-closed arc shape, and its bottom is broken to form a material flow opening. Any two reinforcing rods 262 are connected, and three reinforcing rods 262 are enclosed to form a triangle. The use of a triangular stable structure increases the strength of the cylinder section.

[0080] In this embodiment, the triangle is an equilateral triangle. In other embodiments, the outer contour of the triangle can be adjusted according to actual needs.

[0081] Specifically, the inner wall of the reinforcing ring 261 has three reinforcing parts 2611 that are spaced and protrude inward, and the reinforcing parts 2611 are used to connect with the reinforcing rod 262. One of the reinforcing parts 2611 is arranged on the top of the cylinder and protrudes downward, and the reinforcing part 2611 is located on the transverse center axis of the cylinder section.

[0082] In this embodiment, the size of the reinforcement portion 2611 gradually decreases from the outside to the inside.

[0083] The reinforcing rod 262 has a U-shaped cross section, and includes two side plates 2621 arranged in parallel and spaced apart from each other, and a wing plate 2622 connecting the two side plates 2621, and the wing plate 2622 is attached to the reinforcing portion 2611. The two side plates 2621 and the wing plate 2622 form a groove, and when the reinforcing rod 262 is connected to the reinforcing portion 2611, the opening of the groove is away from the reinforcing portion 2611.

[0084] The reinforcing rod 262 and the reinforcing portion 2611 are fixedly connected by welding.

[0085] Other features of the tank body in this embodiment, such as the upper cylinder 21, the lower cone 22, the head, the fluidizing cone 25 and the reinforcement ring, can refer to the first embodiment and will not be described in detail.

[0086] It can be seen from the above technical solution that the advantages and positive effects of the present invention are:

[0087] The tank body of the present invention comprises two cylinder sections arranged in the axial direction and connected end to end. When the two cylinder sections are assembled to form the tank body, the reinforcing ring plays a role in positioning the two cylinder sections. When the cylinder sections are welded, the reinforcing ring also plays a role in fixing and supporting the cylinder sections, which is convenient for welding, making the welding process between the two cylinder sections simple, thereby simplifying the manufacturing process of the tank body. The reinforcing ring also improves the strength of the entire tank body.

[0088] The reinforcement ring is welded to the two cylinder sections respectively, and the weld between the reinforcement ring and the cylinder section is a circumferential weld, which improves the universality of the production process standards, facilitates mechanized automatic welding, improves the production efficiency of the tank body, and effectively improves the product welding quality, thereby improving the overall product quality.

[0089] Each cylinder section includes an upper cylinder with a semi-elliptical cross section and a lower cone disposed below the upper cylinder. The semi-elliptical upper cylinder widens the width of the entire upper portion of the tank, thereby increasing the volume of the entire tank, that is, increasing the effective loading capacity of the tank, thereby increasing the single transport volume of the tank truck. At the same time, the lower cone at the bottom of the tank adopts a flat cone design, and compared with the traditional tank, the cone portion of the present invention occupies a larger proportion, while increasing the effective loading capacity, increasing the inclination of the lower portion of the tank, so that the material slides smoothly to the bottom, which is more conducive to unloading.

[0090] Compared with the solution of connecting the cylinder and the cone through multiple connecting plates in the related art, due to the complex structure of the connecting plates in the related art, the effective space for loading materials inside the tank is limited and the tank body is heavy. The tank body in this embodiment increases the tank body volume through the structure of the semi-elliptical upper cylinder and the flat cone-shaped lower cone. In addition, the strength of the tank body is increased by the reinforcement ring and the reinforcement ribs. The structure of the reinforcement ring and the reinforcement ribs is simple and the weight is light, which effectively improves the volume utilization of the tank body while reducing the overall weight of the tank body.

[0091] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
