Description

Technical Field

[0001] This application belongs to the field of septic tank truck technology, and particularly relates to a septic tank truck's sludge suction mechanism. Background Technology

[0002] In the field of sanitation equipment technology, vacuum trucks are commonly used as specialized vehicles for pumping and transporting liquid waste such as feces and sewage. Existing vacuum truck suction mechanisms primarily rely on a suction hose to contact the external waste and complete the suction operation. However, due to the complex and diverse actual operating environments, such as differences in the height of waste storage locations, terrain undulations, or obstructions, the position and angle of the suction hose need to be adjusted to ensure that the suction port is accurately aligned with the waste and maintains a good suction effect.

[0003] However, the sewage suction mechanisms commonly found in current market sewage suction trucks generally have shortcomings: the suction hose is only connected to the sewage pump or tank via a simple connection structure, lacking a specially designed adjustment mechanism. In actual operation, when the position of the suction hose needs to be adjusted, it can only be achieved by workers manually dragging, lifting, or bending the hose. This purely manual adjustment method not only consumes a lot of manpower and increases the labor intensity of operators, but also leads to low efficiency in sewage suction operations, requiring improvement. Utility Model Content

[0004] The purpose of this application is to provide a sewage suction mechanism for a septic tank truck that can solve the above-mentioned problems.

[0005] The purpose of this application is to provide a sewage suction mechanism for a septic tank truck, including a vehicle body, and further comprising:

[0006] The tank, mounted on the vehicle body, is used to store the collected waste.

[0007] A suction mechanism, installed on and connected to the tank, is used to suction out waste.

[0008] The suction mechanism is installed on the top of the tank and includes an adjustment mechanism for adjusting the position and a pipe that communicates with the tank.

[0009] The aforementioned septic tank suction truck mechanism effectively solves the problem of manual adjustment of the suction hose in existing technologies by installing an adjustment mechanism within the suction mechanism. The adjustment mechanism, in conjunction with the hose body, allows for adjustment of the suction hose's position and angle, significantly reducing operator workload, avoiding the time-consuming and inefficient manual dragging of the hose, and improving the accuracy and safety of suction operations. It also adapts to the flexible adjustment needs of waste positions in complex working environments. Simultaneously, the tank is equipped with a discharge pipe for waste removal, and the suction mechanism is connected to a vacuum pump, mounted on the chassis and connected to the engine, to provide power for suction.

[0010] Furthermore, the tube body includes:

[0011] First hose;

[0012] First direct management;

[0013] Second hose;

[0014] Second straight pipe;

[0015] The first hose, the first straight pipe, the second hose, and the second straight pipe are connected in sequence and fixed by a sealing ring.

[0016] The tubing body employs a design where a first flexible hose, a first straight pipe, a second flexible hose, and a second straight pipe are connected sequentially and secured with a sealing ring. This design ensures both the integrity and airtightness of the tubing. Utilizing the flexibility of the flexible hoses and the rigidity of the straight pipes, the tubing body allows for angle adjustments via the flexible hose sections while maintaining a stable suction path via the straight pipe sections. Furthermore, it ensures that the position of the plumb line remains constant during vertical adjustment. The segmented structure, when combined with the adjustment mechanism, reduces the risk of blockage caused by excessive bending during adjustment, facilitates the disassembly and maintenance of components, and enhances the overall durability of the mechanism.

[0017] Furthermore: the adjustment mechanism includes:

[0018] The connecting base is rotatably mounted on the tank body, with one end connected to the tank body and the other end connected to the first hose. The connecting base has a built-in drive motor for rotation.

[0019] The adjusting seat has one end set on the connecting base and the other end hinged to a drive frame connected to the tube body.

[0020] An extension seat is mounted on an adjustment seat, and its top is rotatably connected to a driver that is connected to a drive frame;

[0021] The output end of the driver is rotatably connected to the drive frame, and the angle of the drive frame is adjusted by the extension and retraction of the driver.

[0022] In the adjustment mechanism of this application, the connecting base is rotatably mounted on the tank, and its two ends are respectively connected to the tank and the first hose, realizing the horizontal rotation adjustment of the hose relative to the tank. This allows the suction pipe to be circumferentially adjusted around the top of the tank, eliminating the need for manual rotation of the bulky hose. This effectively expands the operating coverage area and is suitable for scenarios where the sewage is distributed in different directions. It solves the problem of fixed hose position and limited adjustment range in the prior art.

[0023] The adjustment seat is connected to the base at one end and the drive frame is hinged to the other end. With the drive on the extension seat, which can be an electric cylinder, pneumatic cylinder or other linear drive, the drive frame is adjusted by the extension and retraction of the drive. The traditional manual lifting and pressing of the hose is transformed into mechanical control of the drive. It can accurately control the pitch angle of the hose, so that the suction port can be quickly aligned with the dirt at different heights. It avoids the angle deviation caused by uneven force during manual adjustment, thereby improving the work efficiency and suction accuracy.

[0024] Furthermore, there are two drives, and a chain is provided on the output shaft. The other end of the chain is rotatably connected to the drive frame, and the drive frame is provided with an extension protrusion connected to the chain.

[0025] By setting the number of actuators to two and connecting them to the extended protrusion of the drive frame via a chain on the output shaft, a more stable driving torque can be provided by utilizing dual power sources, avoiding the uneven force distribution that may occur with a single actuator. The chain connection method can extend the connection length of the actuators and, due to the multi-link nature of the chain, ensures that the connection to the drive frame remains even when the actuators cannot rotate. This is especially beneficial when adjusting downwards, making it more adaptable to complex angle adjustment requirements.

[0026] Furthermore, a connecting sleeve is provided at the end of the drive frame away from the adjustment seat, and the connecting sleeve is fitted onto the first straight tube.

[0027] The end of the drive frame furthest from the adjustment seat is fitted onto the first straight tube via a connecting sleeve, which provides support for the tube body. This allows the adjustment force of the driver to be evenly transmitted to the tube body through the drive frame, avoiding excessive bending or stretching damage caused by direct action on the hose. At the same time, it ensures that the tube body maintains a stable posture during adjustment, preventing the suction effect from being affected by pipe shaking, and effectively extending the service life of the hose.

[0028] Furthermore, the connecting base is provided with a connector, and the first flexible tube is provided with a sealing joint that mates with the connector. The first flexible tube is connected to the connector through a sealing structure.

[0029] The connector of the base mates with the sealing joint of the first hose, enabling quick connection and sealing through a sealing structure. This ensures the airtightness of the pipeline during suction, preventing dirt leakage or air ingress that could affect suction efficiency, while also facilitating the disassembly and assembly of the hose and the tank, making maintenance or replacement of the cleaning hose more convenient.

[0030] The beneficial effects of this application are:

[0031] 1. By installing an adjustment mechanism in the suction mechanism, the problem of the suction hose needing to be manually adjusted in the existing technology can be effectively solved;

[0032] 2. By adjusting the mechanism in conjunction with the pipe body, the position and angle of the suction pipe can be adjusted, significantly reducing the labor intensity of operators, avoiding the time-consuming and inefficient problem of manually dragging the hose, while improving the accuracy and safety of suction operations, and adapting to the flexible adjustment needs of the position of dirt in complex working environments.

[0033] 3. The end of the drive frame furthest from the adjustment seat is fitted onto the first straight tube through a connecting sleeve, which can form a support for the tube body. This allows the adjustment force of the driver to be evenly transmitted to the tube body through the drive frame, avoiding excessive bending or stretching damage caused by direct action on the hose. At the same time, it ensures that the tube body maintains a stable posture during adjustment, preventing the suction effect from being affected by the vibration of the pipeline, and effectively extending the service life of the hose.

[0040] The suction mechanism of the septic tank truck provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0041] Example 1:

[0042] like Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a sewage suction mechanism for a sewage suction truck, including a vehicle body 100, and further including:

[0043] Tank 200, mounted on vehicle body 100, is used to store the collected waste;

[0044] A suction mechanism is installed on and connected to the tank 200 for suctioning waste.

[0045] The suction mechanism is installed on the top of the tank 200 and includes an adjustment mechanism 400 for adjusting the position and a pipe 300 that communicates with the tank 200.

[0046] In some embodiments of this application, such as Figure 1 As shown, the above-mentioned septic tank suction mechanism effectively solves the problem of manual adjustment of the suction hose in existing technologies by installing an adjustment mechanism 400 in the suction mechanism. The adjustment mechanism 400, in conjunction with the hose body 300, allows for adjustment of the position and angle of the suction pipe, significantly reducing the labor intensity of operators, avoiding the time-consuming and inefficient problem of manually dragging the hose, and improving the accuracy and safety of suction operations, adapting to the flexible adjustment needs of sewage positions in complex working environments. Simultaneously, the tank body 200 is equipped with a sewage discharge pipe, and the suction mechanism is connected to a vacuum pump, mounted on the chassis of the vehicle body 100 and connected to the engine, to provide a power source for suction.

[0047] Example 2:

[0048] This application provides a sludge suction mechanism for a sludge suction truck. In addition to the above-mentioned technical features, the sludge suction mechanism of this application also includes the following technical features.

[0049] like Figure 2 As shown, the tube body 300 includes:

[0050] First hose 310;

[0051] The first direct line is 320;

[0052] Second hose 330;

[0053] Second straight pipe 340;

[0054] The first hose 310, the first straight pipe 320, the second hose 330, and the second straight pipe 340 are connected in sequence and fixed by a sealing ring 350.

[0055] In this embodiment, the pipe body 300 is designed with a first flexible hose 310, a first straight pipe 320, a second flexible hose 330, and a second straight pipe 340 connected in sequence and fixed by a sealing ring 350. While ensuring the pipe's connectivity and sealing, the flexibility of the flexible hoses and the rigid support of the straight pipes allow the pipe body 300 to adjust its bending angle via the flexible hose sections and maintain a stable suction path via the straight pipe sections. Furthermore, the position of the vertical point remains unchanged during vertical adjustment. The segmented structure, when used in conjunction with the adjustment mechanism 400, reduces the risk of blockage caused by excessive bending during adjustment, facilitates the disassembly and maintenance of components, and improves the overall durability of the mechanism.

[0056] Example 3:

[0057] This application provides a sludge suction mechanism for a sludge suction truck. In addition to the above-mentioned technical features, the sludge suction mechanism of this application also includes the following technical features.

[0058] like Figure 2 and Figure 3 As shown, the adjustment mechanism 400 includes:

[0059] The connecting base 410 is rotatably mounted on the tank 200. One end of the base is connected to the tank 200, and the other end is connected to the first hose 310. The connecting base 410 has a built-in drive motor for rotation.

[0060] The adjusting seat 420 has one end mounted on the connecting base 410 and the other end hinged to a drive frame 430 connected to the tube body 300.

[0061] An extension seat 440 is mounted on an adjustment seat 420, and a driver 450 connected to a drive frame 430 is rotatably connected to its top.

[0062] The output end of the driver 450 is rotatably connected to the drive frame 430, and the driver 450 drives the drive frame 430 to adjust its angle through extension and retraction.

[0063] In this embodiment, the connecting base 410 is rotatably mounted on the tank 200 in the adjustment mechanism 400. Its two ends are respectively connected to the tank 200 and the first hose 310, realizing the horizontal rotation adjustment of the hose 300 relative to the tank 200. This allows the suction pipe to be circumferentially adjusted around the top of the tank 200 without the need for manual rotation of the bulky hose, thereby effectively expanding the operating coverage area. It is suitable for scenarios where the sewage is distributed in different directions, and solves the problem of fixed hose position and limited adjustment range in the prior art.

[0064] The adjusting seat 420 is connected to the base 410 at one end and the drive frame 430 is hinged to the other end. It works with the driver 450 on the extension seat 440. The driver 450 can be an electric cylinder, a pneumatic cylinder, or other linear driver. The extension and retraction of the driver 450 drives the drive frame 430 to adjust the angle. This transforms the traditional manual lifting and pressing of the hose into mechanical control of the driver 450. It can precisely control the pitch angle of the hose 300, so that the suction port can be quickly aligned with the dirt at different heights. This avoids the angle deviation caused by uneven force during manual adjustment, thereby improving work efficiency and suction accuracy.

[0065] The connecting base 200 has a built-in drive motor that enables automated rotation of the connecting base 410. Compared to the manual rotation of the hose to adjust its position in the prior art, the structure described in this application can quickly and accurately control the circumferential rotation angle of the hose 300. Especially in large-area operation scenarios, it can significantly reduce the position adjustment time and further improve the automation and efficiency of the vacuuming operation.

[0066] Example 4:

[0067] This application provides a sludge suction mechanism for a sludge suction truck. In addition to the above-mentioned technical features, the sludge suction mechanism of this application also includes the following technical features.

[0068] like Figure 3 As shown, there are two drivers 450, and a chain 451 is provided on the output shaft. The other end of the chain 451 is rotatably connected to the drive frame 430. An extension protrusion 452 connected to the chain 451 is provided on the drive frame 430.

[0069] In this embodiment, two actuators 450 are used, and they are connected to the extension protrusion 452 of the drive frame 430 via a chain 451 on the output shaft. By utilizing dual power sources, a more stable driving torque can be provided, avoiding the uneven force distribution that may occur with a single actuator 450. The chain 451 connection method can extend the connection length of the actuators 450, and the multi-link characteristic of the chain 451 can ensure that the actuators 450 can still be connected to the drive frame 430 even if they cannot rotate. This is especially suitable for complex angle adjustment requirements when adjusting downwards.

[0070] Furthermore, a connecting sleeve 431 is provided at the end of the drive frame 430 away from the adjustment seat 420, and the connecting sleeve 431 is fitted onto the first straight tube 320.

[0071] The end of the drive frame 430 away from the adjustment seat 420 is fitted onto the first straight tube 320 through the connecting sleeve 431, which can form a support for the tube body 300. This allows the adjustment force of the driver 450 to be evenly transmitted to the tube body 300 through the drive frame 430, avoiding excessive bending or stretching damage caused by direct action on the hose. At the same time, it ensures that the tube body 300 maintains a stable posture during adjustment, preventing the suction effect from being affected by pipe shaking, and effectively extending the service life of the hose.

[0072] Example 5:

[0073] This application provides a sludge suction mechanism for a sludge suction truck. In addition to the above-mentioned technical features, the sludge suction mechanism of this application also includes the following technical features.

[0074] like Figure 3 As shown, a connector 411 is provided on the connecting base 410, and a sealing connector 412 that mates with the connector 411 is provided on the first flexible hose 310. The first flexible hose 310 is connected to the connector 411 through a sealing structure.

[0075] In this embodiment, the connector 411 of the connecting base 410 cooperates with the sealing connector 412 of the first hose 310, and the sealing structure enables quick connection and sealing. This ensures the airtightness of the pipeline during suction, preventing dirt leakage or air ingress that could affect suction efficiency, and also facilitates the disassembly and assembly of the hose and the tank 200, making maintenance or replacement of the cleaning hose more convenient.
