Description

Technical Field

[0001] This utility model relates to the field of concrete mixer truck leak prevention technology, specifically to a leak prevention tool for the mixing and filling port of a concrete mixer truck. Background Technology

[0002] In the field of concrete mixer truck leak prevention technology, existing concrete mixer trucks typically have leak prevention devices installed at the mixing inlet during the mixing and transportation process. Some leak prevention tools use a receiving funnel in conjunction with a leak prevention cylinder and a collection mechanism to collect leaking concrete for convenient centralized treatment; others use a leak prevention plate structure to guide concrete leaking from the gap between the guide cylinder and the feed hopper back into the tank, thereby achieving the leak prevention function.

[0003] However, existing technologies have significant shortcomings. On the one hand, when the concrete mixer truck stops pouring, the mixing tank may continue to rotate due to its rolling inertia, causing concrete to overflow from the mixing inlet. Existing leak-proof tools are ineffective in dealing with this leakage problem caused by inertia. On the other hand, most existing leak-proof tools for concrete mixer trucks need to be assembled with the concrete mixer truck, which is inconvenient to disassemble. Furthermore, they lack flexibility when adapting to mixing tanks of different diameters, affecting the ease of use and applicability of the leak-proof tools. Utility Model Content

[0004] This utility model aims to provide a leak-proof tool for the mixing and pouring inlet of a concrete mixer truck, in order to solve the problems of concrete overflow caused by the rolling inertia when the concrete mixer truck stops pouring, and the inconvenience of disassembling existing leak-proof tools that need to be assembled with the concrete mixer truck. To solve the above-mentioned technical problems, the present invention provides the following technical solution: a leak-proof tool for the mixing inlet of a concrete mixer truck, comprising a fixing component and a leak-proof component, wherein the fixing component is connected to one end of the mixing tank where the mixing inlet is located, one end of the leak-proof component is connected to the fixing component, and the other end of the leak-proof component is connected to the discharge funnel.

[0005] The working principle of this utility model is as follows: When the leak-proof tool is working, the fixing component is connected to the end of the mixing tank with the mixing inlet, so that the leak-proof tool is stably fixed at the mixing tank inlet, avoiding structural failure due to the rotation of the tank. One end of the leak-proof component is connected to the fixing component and the other end is connected to the discharge funnel, which can form a pocket-shaped structure that is lower than the top of the mixing inlet and higher than the bottom of the mixing inlet. When the tank rotates and spills concrete, the spilled material will fall onto the leak-proof component and be guided back into the mixing tank, preventing the concrete from overflowing directly. This solves the problem of concrete overflowing due to the rolling inertia when the concrete truck stops pouring. Moreover, this structure does not need to be permanently assembled with the concrete truck, is easy to disassemble, and can adapt to the leak-proof requirements under different working conditions.

[0006] The beneficial effects of this invention are as follows: By incorporating a fixing component and a leak-proof component, the problem of concrete overflow due to rolling inertia when the concrete mixer truck stops pouring can be effectively solved. Specifically, the fixing component is connected to the end of the mixing tank with the mixing inlet, ensuring the leak-proof tool is stably fixed at the mixing tank inlet, preventing structural failure due to tank rotation. The leak-proof component is connected at one end to the fixing component and at the other end to the discharge funnel, forming a pocket-shaped structure lower than the top and higher than the bottom of the mixing inlet. When the tank rotates and spills concrete, the spilled material falls onto the leak-proof component and is guided back into the mixing tank, preventing direct overflow. Furthermore, this structure does not require permanent assembly with the concrete mixer truck, making disassembly convenient. The connection method of the fixing and leak-proof components can adapt to leak-proof requirements under different working conditions, improving the practicality and flexibility of the leak-proof tool.

[0007] Furthermore, the fixing assembly includes a large clamp and a small clamp, connected by a chain. Both the large and small clamps are composed of two semi-circular clamps connected together. The connection of the large clamp, small clamp, and chain allows for adaptation to different diameter sections of the mixing tank opening and enhances the stability of the fixing assembly.

[0008] Furthermore, the semi-circular clamp is divided into two parts, and the two separate semi-circular clamps are connected by a spring. The semi-circular clamps are connected by a spring and can elastically expand and contract to adapt to different tank diameters, facilitating installation and fixation.

[0009] Furthermore, the diameter of the semi-circular clamp of the large clamp is larger than the diameter of the semi-circular clamp of the small clamp. This larger diameter of the large clamp accommodates the tapered structure of the mixing tank opening, improving the installation stability of the fixing components.

[0010] Furthermore, both the large and small clamps have grooves on their radial sides, and rollers are installed in each groove. The rollers in the grooves reduce friction between the large and small clamps and the mixing tank, allowing the tank to rotate freely while the clamps remain stationary.

[0011] Furthermore, the leak-proof component includes a telescopic steel rod and a plastic cloth. The telescopic steel rod is connected to one end of a large clamp, and the telescopic steel rod and the large clamp are on the same horizontal plane. One side of the plastic cloth is connected to the telescopic steel rod, and multiple elastic hooks are connected to the opposite side of the plastic cloth. The cooperation between the telescopic steel rod and the plastic cloth allows for flexible adjustment of the length of the leak-proof component, forming a pocket-like structure to collect leaked material and guide it back to the mixing tank.

[0012] Furthermore, multiple elastic hooks are also connected to the other two sides of the plastic fabric. The elastic hooks on both sides of the plastic fabric facilitate the assembly and disassembly of the leak-proof component and the feeding funnel, enhancing the flexibility and stability of the connection.

[0015] The following detailed description illustrates the specific implementation method: The basic implementation examples are as follows: Figures 1-3 The diagram shows a leak-proof tool for the mixing inlet of a concrete mixer truck, comprising a fixing component, a telescopic steel rod 8, and a plastic cloth 7. The fixing component includes a large clamp 1 and a small clamp 10. One side of the telescopic steel rod 8 is fixedly connected to the bottom side wall of the large clamp 1, and the other side of the telescopic steel rod 8 is slidably attached to the side of the discharge funnel near the mixing tank. The telescopic steel rod 8 and the large clamp 1 are located on the same horizontal plane. The telescopic steel rod 8 has six through telescopic holes 5. The top two ends of the plastic cloth 7 are fixedly connected to the two ends of the telescopic steel rod 8. The remaining three sides of the plastic cloth 7 are fixedly connected with twelve elastic hooks 6. The diameter of the large clamp 1 is larger than the diameter of the small clamp 10. Four chains 3 are fixedly connected between the large clamp 1 and the small clamp 10. Both the large clamp 1 and the small clamp 10 are composed of four quarter-ring bars. The four ring bars are fixedly connected in pairs using springs 4. The two ends of each pair of ring bars are detachably connected using a bolt 2 and two nuts. The centripetal side of the ring bar has a groove, and four rollers 9 are rotatably connected in the groove.

[0016] The specific implementation process is as follows: The large clamp 1 and the small clamp 10 are assembled into a ring by bolts 2 and two nuts and fitted at different diameters of the mixing tank opening. The rollers 9 inside the large clamp 1 and the small clamp 10 are in contact with the surface of the tank, allowing the tank to rotate freely while the large clamp 1 and the small clamp remain stationary. The springs 4 set in the large clamp 1 and the small clamp 10 allow for a certain degree of elastic expansion and contraction to adapt to different tank diameters. The chain 3 prevents the large clamp 1 and the small clamp 10 from shaking violently. When the tank truck stops pouring, the tank continues to roll due to inertia. At this time, the large clamp 1 remains stationary, avoiding structural failure of the overall anti-leakage tool due to the rotation of the tank.

[0017] According to the length of the discharge funnel, use bolts 2 to fix the length of the telescopic steel rod 8. Fix one side of the telescopic steel rod 8 to the outside of one end of the large clamp 1, and slide and fit the other side of the discharge funnel close to the mixing tank. At this time, the high-strength elastic plastic cloth 7 unfolds, and the elastic hook 6 of the plastic cloth 7 is detachably connected to the side of the discharge funnel away from the mixing tank, forming a pocket-shaped structure that is lower than the top of the mixing inlet and higher than the bottom of the mixing inlet. When the tank rotates and spills concrete, the concrete will fall onto the plastic cloth 7. Since the lowest point of the cloth is higher than the bottom of the mixing inlet, the spilled material will be received by the plastic cloth 7 and guided back into the mixing tank, and cannot overflow directly outside the mixing tank, thereby preventing the concrete from being wasted due to inertial rolling and achieving the anti-leakage function.

[0018] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
