Description

Technical Field

[0001] This utility model relates to the field of suction and discharge vehicle technology, and in particular to an unloading auxiliary device for suction and discharge vehicles. Background Technology

[0002] Suction and discharge trucks, as specialized vehicles for the transfer and discharge of liquid, semi-liquid, and solid-containing materials, are widely used in municipal sanitation, chemical transportation, and agricultural production. The unloading process is a crucial step in achieving efficient material transfer. During unloading, suction and discharge trucks typically combine two methods: pumping pressure or gravitational potential energy. When handling high-viscosity materials or requiring long-distance unloading, the vehicle activates its onboard hydraulic or vacuum pump, using high-pressure thrust within the pipeline to quickly push the material to the designated location. For materials with better flowability, the vehicle's height and tilt create gravitational potential energy, allowing the material to naturally discharge along the unloading pipeline. This flexible combination of methods improves overall operational efficiency.

[0003] However, traditional unloading methods still have limitations in practical applications. Since materials must be discharged directly through the unloading pipe, driven by pumping pressure or accelerated by gravity, the material rushes out of the pipe outlet at a relatively high speed, easily causing splashing and spraying at the moment of discharge due to excessive flow velocity. This splashed material not only pollutes the surrounding ground, equipment, and air, increasing subsequent cleaning workload, but may also lead to unnecessary material waste. Some suction and discharge trucks are simply equipped with anti-splash auxiliary devices, but when handling granular or powdery materials, solid particles or powders easily accumulate in the narrow channels of the anti-splash device, especially when the material has high moisture content or uneven particle diameter, making it easier to clog the device's interface or internal pipes. This not only affects the smoothness of unloading but may also cause a sudden increase in pressure within the pipes due to blockage, increasing the risk of equipment failure. Therefore, the field of suction and discharge truck technology needs to propose an unloading auxiliary device that can avoid splashing and blockage. Utility Model Content

[0004] In view of the above-mentioned prior art, the present invention provides an unloading auxiliary device for a suction and discharge vehicle, mainly solving the technical problem of how to avoid splashing and clogging. To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: An auxiliary device for unloading a suction and discharge vehicle includes a connecting ring, a housing, a tray, a connecting rod, a first spring, and a second spring. The connecting ring is fixedly connected to the top of the housing. The housing is flared, narrower at the top and wider at the bottom. The tray is located at the lower opening of the housing. The edge of the tray is fixedly connected to the connecting rod. One side of the connecting rod is connected to the housing via the first spring and the second spring. The first spring and the second spring are inclined and symmetrically arranged on both sides of the connecting rod. The tray is vertically movable to the housing via the first spring and the second spring.

[0005] Preferably, the connecting ring is composed of two semi-circular rings joined together, and bolt holes are provided on both sides of the connecting ring.

[0006] Preferably, a V-shaped plate is provided at the connection between the connecting rod and the first spring and the second spring, the upper ends of the first spring and the second spring are respectively fixedly connected to the two sides of the V-shaped plate, and the upper end of the connecting rod is fixedly connected to the V-shaped plate.

[0007] Preferably, the tray is configured as an arc-shaped structure with a central protrusion.

[0008] Preferably, a pull ring is provided at the bottom of the tray, and the pull ring is fixedly connected to the bottom of the tray.

[0009] Preferably, a limiting ring is provided at the edge of the outer shell, the limiting ring is fixedly connected to the outer shell through a connecting post, and the connecting rod is disposed between the limiting ring and the outer shell.

[0010] Preferably, the connecting rod, the first spring, and the second spring are arranged in a plurality of uniform rings on the outer side of the outer casing.

[0011] Preferably, the connecting post is disposed at the middle of an adjacent connecting rod.

[0012] The beneficial effects of this utility model are as follows: By setting a connecting ring, this application can detachably connect the connecting ring to the unloading pipe. The outer shell and the pallet cooperate to block the fast-flowing material from the pallet, reducing the flow rate. At the same time, the outer shell can shield the material splashing when it impacts the pallet, thereby reducing the material flow rate and suppressing splashing, and preventing the material from spraying and splashing when it flows into the material container or material pool.

[0013] Meanwhile, by setting a first spring and a second spring, this application enables the pallet to vibrate slightly when impacted by materials, thereby shaking off the materials adhering to and accumulating on the pallet and preventing accumulation and blockage. Furthermore, the device is symmetrically equipped with a first spring and a second spring. Due to the irregular vibration of the pallet, the first spring and the second spring are subjected to different forces, resulting in different tensions, which causes the pallet to rotate slightly. The slight vibration and rotation work together to effectively prevent material blockage.

[0014] In summary, this application, by incorporating a tray, a housing, a first spring, and a second spring, can simultaneously prevent material splashing and blockage. Attached Figure Description

[0018] Example 1 See attached document Figure 1 This application provides an auxiliary device for unloading a suction and discharge vehicle, including a connecting ring 1, a housing 2, a support plate 3, a connecting rod 4, a first spring 5, and a second spring 6. The connecting ring 1 is fixedly connected to the top of the housing 2. The housing 2 is shaped like a trumpet, narrower at the top and wider at the bottom. The support plate 3 is located at the lower opening of the housing 2. The edge of the support plate 3 is fixedly connected to the connecting rod 4. One side of the connecting rod 4 is connected to the housing 2 via the first spring 5 and the second spring 6. The first spring 5 and the second spring 6 are inclined and symmetrically arranged on both sides of the connecting rod 4. The support plate 3 is vertically movable to the housing 2 via the first spring 5 and the second spring 6. By setting the connecting ring 1, this device can be detachably connected to the unloading pipe. The housing 2 and the support plate 3 work together to block the fast-flowing material from being splashed by the support plate 3, reducing the flow rate. At the same time, the housing 2 can shield the material splashing from impacting the support plate 3, thereby reducing the material flow rate and suppressing splashing, preventing the material from spraying and splashing when it flows into the material container or material pool. Meanwhile, by incorporating a first spring 5 and a second spring 6, this device causes the pallet 3 to vibrate slightly when impacted by material, thereby shaking off the material adhering to and accumulating on the pallet 3, preventing accumulation and blockage. Furthermore, the symmetrical arrangement of the first spring 5 and the second spring 6, due to the irregular vibration of the pallet 3, results in different forces on the first spring 5 and the second spring 6, leading to different pulling forces and causing the pallet 3 to rotate slightly. This slight vibration combined with rotation effectively prevents material blockage. In summary, this device, by incorporating the pallet 3, the outer casing 2, the first spring 5, and the second spring 6, can simultaneously prevent material splashing and blockage.

[0019] Specifically, the connecting ring 1 is composed of two semi-circular rings joined together, and bolt holes 7 are provided on both sides of the connecting ring 1. When the connecting ring 1 needs to be connected to the unloading pipe, bolts can be passed through the connecting ring 1 and locked, thereby fixing the connecting ring 1 to the unloading pipe.

[0020] Specifically, a V-shaped plate 8 is provided at the connection between the connecting rod 4 and the first spring 5 and the second spring 6. The upper ends of the first spring 5 and the second spring 6 are respectively fixedly connected to the two sides of the V-shaped plate 8, and the upper end of the connecting rod 4 is fixedly connected to the V-shaped plate 8. The V-shaped plate 8 in this device can improve the stability of the connection between the first spring 5 and the second spring 6 and the connecting rod 4. In this embodiment, the first spring 5 and the second spring 6 are fixedly connected to the outer shell 2 and the V-shaped plate 8 by welding. The V-shaped plate 8 is also connected to the connecting rod 4 and the connecting ring 1 to the outer shell 2 by welding.

[0021] Example 2 See attached document Figure 2-3 The difference between this embodiment and embodiment 1 is that the pallet 3 is set as an arc-shaped structure with a central protrusion, which can prevent material from accumulating and staying in the middle of the pallet 3. At the same time, the pallet 3 in this device can increase the central protrusion to reduce the possibility of material accumulation, or decrease the central protrusion to improve the effect of reducing the material flow rate, depending on actual needs.

[0022] Specifically, a pull ring 9 is provided at the bottom of the pallet 3, and the pull ring 9 is fixedly connected to the bottom of the pallet 3. By providing the pull ring 9, when excessive material accumulates above the pallet 3, causing blockage and preventing normal unloading of the pipeline, the operator can connect a straight rod or hook to the pull ring 9 and pull downwards, while also moving the pallet 3 left and right and twisting it to allow the material above the pallet 3 to fall off without contacting the material or the device itself, thus reducing safety risks.

[0023] Specifically, a limiting ring 10 is provided on the edge of the outer shell 2. The limiting ring 10 is fixedly connected to the outer shell 2 through a connecting post 11. The connecting rod 4 is disposed between the limiting ring 10 and the outer shell 2. The limiting ring 10 can prevent the connecting rod 4 from causing the pallet 3 to shake randomly, resulting in uneven material discharge around the pallet 3, thereby increasing the possibility of blockage.

[0024] Specifically, the connecting rod 4, the first spring 5, and the second spring 6 are all arranged in a uniform ring on the outside of the outer casing 2. In this embodiment, four sets of connecting rods 4, first springs 5, and second springs 6 are provided and are evenly arranged in a ring on the outside of the outer casing 2.

[0025] Specifically, the connecting post 11 is located in the middle of the adjacent connecting rod 4, which can prevent the connecting post 11 from affecting the rotation of the connecting rod 4 on the support plate 3.

[0026] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
