Description

Technical Field

[0001] This utility model relates to the field of tank-type rear-trailer technology, and in particular to a tank-type rear-trailer structure. Background Technology

[0002] In the field of bulk material transportation, especially for powdery or highly free-flowing goods, achieving efficient, clean, and controllable unloading is a crucial step. The significance of tank-type rear-tipping trailers lies in providing a large-capacity transportation solution that can adapt to different unloading sites and process requirements. It needs to balance transportation and unloading efficiency, ensuring minimal material residue and dust during transfer, while also meeting the precise control requirements for emission flow and methods in certain specific operational scenarios, thereby improving the reliability and economy of the entire logistics process.

[0003] In existing technologies, a common approach is to use a tank fixed to a trailer chassis to load materials. When discharge is required, the rear of the tank is lifted by the extension and retraction of a hydraulic cylinder located between the front of the tank and the chassis, causing it to rotate around the hinge point at the bottom of the rear of the tank, thus forming an inclined posture with the front lower and the rear higher. The materials inside the tank mainly rely on their own gravity to flow to the outlet located at the lower end of the tank and achieve gravity discharge, completing the unloading operation.

[0004] However, new technical problems have emerged during the actual use of the aforementioned existing technologies. First, when the tank tilts to discharge material, the material suddenly plunges downwards and gathers towards the rear, accelerating its impact. Since the rear sidewalls of the tank are typically vertical or angled planes, lacking effective guiding and collecting structures, a large amount of material easily splashes from the sidewalls or scatters in all directions upon reaching the outlet area, resulting in material waste and pollution of the working environment. Second, existing emission control methods are relatively crude, usually only using simple gates at the outlet for fully open or fully closed operations. This makes it impossible to finely and continuously regulate the flow rate of material passing through the outlet during the discharge process, failing to meet the requirements of production processes or packaging operations that require precise emission control, thus limiting the application scope and operational flexibility of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a tank-type rear tipper structure that solves the technical problems in the prior art where materials are easily splashed and scattered from the side wall when the tank is tilted for discharge, and the discharge volume cannot be accurately adjusted.

[0006] To achieve the above objectives, this utility model provides a tank-type rear-tipping trailer structure, including a trailer. The rear side of the top of the trailer's mounting plate is connected to the rear side of the bottom of the tank compartment via a pin. An upper inclined plate is fixedly installed on the rear side of the top of the tank compartment and connected to the top of the rear side wall of the tank compartment. An extension plate is fixedly installed on the top of the front side wall of the tank compartment. Three inclined bracing plates are spaced apart at the angle between the extension plate and the tank compartment. Hydraulic rods are respectively provided at the bottom of the extension plate and between the inclined bracing plates. The bottom of the hydraulic rods is located at the top of a hydraulic cylinder. The bottom of the hydraulic cylinder is located at the top of the trailer's mounting plate near the front of the trailer. Rotary pairs formed by a rotating plate, a rotating clamp, and a pin are respectively provided between the hydraulic cylinder and the trailer's mounting plate, and between the hydraulic rod and the extension plate.

[0007] The tank has a discharge slot on its rear side wall, and a door is installed on the outside of the tank opposite the discharge slot via a hinge. Three discharge connectors are installed on the door via bolts.

[0008] The discharge connector has two sealing rings embedded inside, and the opening of the discharge connector is fitted with a sealing ring by bolts.

[0009] The discharge connector has an assembly block fixedly installed at its top, and an extension block is installed at its top by bolts. The assembly block and the extension block have through holes that communicate with the interior of the discharge connector.

[0010] A gate plate passes through the through hole and extends into the discharge connector. The gate plate is located inside the discharge connector and is held between two sealing rings.

[0011] Each of the extension blocks has a support frame bolted to its top, and a threaded rod threaded to the middle of the top of each support frame.

[0012] The bottom end of the threaded rod is rotatably connected to the top end of the pull rod, and the bottom end of the pull rod is fixedly installed in the middle of the top of the gate plate.

[0013] This utility model discloses a tank-type rear-tipping trailer structure. The trailer's mounting plate is connected to the rear bottom of the tank using a pin shaft, providing a stable rotational foundation for the tank's tilting. An upper inclined plate is fixedly connected to the rear top of the tank. This inclined plate, together with the rear sidewall of the tank, forms a guiding structure that collects and guides the material flowing backward during the tilt, helping to reduce splashing and scattering caused by direct impact with the sidewall. An extension plate at the top of the front sidewall of the tank is connected to the tank with a diagonal brace to enhance the structural stability of this connection. The drive system uses a hydraulic cylinder to push a hydraulic rod, which in turn lifts the extension plate, raising the front of the tank for tilted unloading. Rotating pairs between the hydraulic cylinder and the mounting plate, and between the hydraulic rod and the extension plate, effectively adapt to angle changes during lifting, ensuring smooth operation. Furthermore, a discharge slot and a door are provided on the rear sidewall of the tank, offering a primary rapid discharge channel. The discharge connector installed on the door allows for small-flow or controlled discharge. The discharge connector has an embedded sealing ring, and the flow channel is opened and closed by raising and lowering a gate. The gate is inserted through a through hole in the assembly block and the extension block, and its top is connected to a threaded rod via a pull rod. By rotating the threaded rod on the support frame, the gate can be precisely raised and lowered, thereby achieving continuous adjustment of the discharge opening size to meet the control requirements of material discharge. This structural design aims to improve the concentration of materials during the discharge process and enhance the controllability and flexibility of the discharge operation.

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-4 A tank-type rear-tipping trailer 101 structure includes a trailer 101 serving as a basic transport platform, with a mounting plate 102 fixed to the trailer 101. The tank 103, as the core container for loading materials, has its bottom rear side hinged to the rear side of the mounting plate 102 via a pin, forming a fixed rotation fulcrum for the tank 103's tilting. An upper inclined plate 104 is fixedly installed on the rear top side of the tank 103, connecting to the top of the rear sidewall of the tank 103. Its function is to form a guide shield when the tank 103 tilts, guiding the material to flow towards the outlet area. An extension plate 105 is fixedly installed on the top of the front sidewall of the tank 103, with three diagonal bracing plates 106 spaced apart at the angle between the extension plate 105 and the front sidewall of the tank 103 to enhance the extension. The structural strength and stability of the connection between plate 105 and tank 103 are ensured. Hydraulic rods 107 are installed at the bottom of the extension plate 105 and between the diagonal bracing plates 106. The bottom end of the hydraulic rod 107 is located at the top of the hydraulic cylinder 108, and the bottom end of the hydraulic cylinder 108 is located at the top of the hanging plate 102 of the trailer 101 near the front of the vehicle. Rotary pairs 109, formed by rotating plates, rotating clamps and pins, are provided between the hydraulic cylinder 108 and the hanging plate 102 and between the hydraulic rod 107 and the extension plate 105. Their function is to enable the hydraulic lifting mechanism to adapt to the angle changes during the lifting process and avoid generating harmful internal stress.

[0022] A discharge trough 110 for large-flow unloading is provided on the rear side wall of the tank 103; a tank door 111 is installed on the outside of the tank 103 opposite to the discharge trough 110 by means of hinges, for opening or closing the discharge trough 110; three discharge connectors 112 are installed on the tank door 111 by means of bolts, and these discharge connectors 112 provide interfaces for small-flow or precise control of discharge; two sealing rings 113 are embedded inside each discharge connector 112 to form a reliable sealing interface; a sealing ring 114 is also installed at the opening of the discharge connector 112 by means of bolts to close and reinforce the connector outlet.

[0023] An assembly block 115 is fixedly installed at the top of the discharge connector 112, and an extension block 116 is bolted to the top of the assembly block 115. A through hole 117 is provided on both the assembly block 115 and the extension block 116, communicating with the interior of the discharge connector 112. A gate 118 passes through the through hole 117 and extends into the discharge connector 112. The portion of the gate 118 inside the discharge connector 112 is clamped between two sealing rings 113, and its up-and-down movement controls the opening and closing of the channel and regulates the flow rate. Support frames 119 are bolted to the top of the extension block 116 to provide support for the control mechanism. A threaded rod 120 is threadedly installed at the top center of the support frame 119. The bottom end of the threaded rod 120 is rotatably connected to the top end of a pull rod 121, while the bottom end of the pull rod 121 is fixedly installed at the top center of the gate plate 118. When the threaded rod 120 is rotated, it drives the pull rod 121 and the gate plate 118 fixed thereto to move up and down through the threaded transmission, thereby precisely controlling the insertion depth of the gate plate 118 relative to the sealing ring 113, realizing stepless adjustment of the opening of the discharge channel and quantitative discharge of materials.

[0024] Working principle: The trailer 101 serves as a mobile base, towed by a tractor for transportation, carrying the entire tank 103 and its internal materials. The tank 103 is connected to the trailer 101's mounting plate 102 via a pin on its rear bottom end, which forms a fixed fulcrum for the tank 103 to tilt. When unloading is required, the hydraulic cylinder 108 is activated, driving the hydraulic rod 107 to extend from the top of the hydraulic cylinder 108. The bottom end of the hydraulic rod 107 acts on the hydraulic cylinder 108, while the top end of the hydraulic rod 107 pushes the extension plate 105 upward. Rotating pairs 109 are provided between the hydraulic cylinder 108 and the trailer 101's mounting plate 102, and between the hydraulic rod 107 and the extension plate 105. These rotating pairs 109 are formed by rotating plates, rotating clamps, and pins, allowing the hydraulic drive components to freely adapt to angle changes during the lifting process, avoiding structural stress caused by rigid connections, and ensuring smooth lifting operations.

[0025] Driven by the hydraulic rod 107, the extension plate 105 is lifted upwards. Since the extension plate 105 is fixedly installed on the top of the front side wall of the tank 103, it drives the front of the tank 103 to rise as a whole. At this time, the pin on the rear side of the bottom of the tank 103 acts as a rotation hub, causing the tank 103 to tilt backwards in a manner where the front rises and the rear rotates around the pin. This results in the tank 103 forming an inclined state with the front higher than the rear, creating conditions for the material to slide downwards and be discharged by its own weight. The upper inclined plate 104, fixed to the rear side of the top of the tank 103, is connected to the top of the rear side wall of the tank 103. When the tank 103 is in an inclined position, the upper inclined plate 104 and the rear side wall of the tank 103 together form a downward guiding bucket-shaped cover. This structure can effectively collect the material sliding from the inside of the tank 103 to the rear and guide it to flow toward the predetermined outlet area, preventing the material from splashing or scattering outwards during the discharge process, and ensuring the concentration and controllability of the material flow.

[0026] A discharge port 110 is provided on the rear side wall of the tank 103, which provides the main channel for the rapid discharge of large flow rates of materials. Opposite to the discharge port 110, a door 111 is installed by a hinge, which can be opened or closed to control the opening and closing of the discharge port 110. Discharge connectors 112 are bolted to the door 111, which are used for discharge scenarios requiring smaller flow rates or more precise control. Two sealing rings 113 are embedded inside the discharge connectors 112, which provide an elastic contact surface for the sealing of the gate 118. A sealing ring 114 is also bolted to the opening of the discharge connector 112, which further reinforces the structural integrity of the outlet of the discharge connector 112.

[0027] An assembly block 115 is fixedly installed at the top of the discharge connector 112, and an extension block 116 is bolted to the top of the assembly block 115. This split structure facilitates processing and assembly. A through hole 117 is opened at the same position on the assembly block 115 and the extension block 116, which communicates with the interior of the discharge connector 112. The gate 118 passes through the through hole 117 and extends into the interior of the discharge connector 112. The part of the gate 118 inside the discharge connector 112 is precisely clamped between two sealing rings 113, and the flow channel is opened and closed by moving up and down. A support frame 119 is bolted to the top of the extension block 116, providing a stable mounting base for the control mechanism. A threaded rod 120 is threaded to the middle of the top of the support frame 119. When it is necessary to control the discharge, the threaded rod 120 is rotated, and the rotational motion is converted into linear motion by using the thread transmission principle. The bottom end of the threaded rod 120 is rotatably connected to the top end of the pull rod 121, while the bottom end of the pull rod 121 is fixedly installed at the top center of the gate 118. Therefore, the rotation of the threaded rod 120 will drive the pull rod 121 and the gate 118 to move up and down together.

[0028] By precisely adjusting the number of rotations of the threaded rod 120, the insertion depth of the gate 118 in the through hole 117 and the discharge connector 112 can be controlled, that is, the opening gap of the gate 118 relative to the two sealing rings 113 can be adjusted, thereby achieving precise control from complete closure to different opening degrees, and ultimately achieving precise regulation and quantitative discharge of material discharge flow. The entire system, through the coordinated work of its components, achieves safe tilting of the tank 103, effective guidance of materials, and precise control of the discharge process.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
