Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage ditch dredging technology, and in particular to a device for dredging urban drainage ditches. Background Technology
[0002] Drainage ditches commonly contain a mixture of garbage, fallen leaves, and silt. For example, if fallen leaves are not cleared in time during autumn and winter, they can easily form "bamboo-joint ditches" during the rainy season, blocking drainage channels. In residential and commercial areas, household garbage dumped indiscriminately by residents often mixes with mud and sand from car wash wastewater, causing pipes to narrow or even become completely blocked.
[0003] Traditional manual cleaning of drainage ditches faces multiple operational challenges. The working environment is generally harsh, with ditches filled with silt, sewage, domestic waste, and rotting debris, emitting a pungent stench and easily breeding mosquitoes and germs.
[0004] Ordinary cleaning machines have significant shortcomings in the real-time transportation of waste. Although most machines can loosen waste through mixing and digging, they lack a supporting continuous conveying device. As a result, the cleaned sludge and garbage often accumulate around the work site or inside the pipeline. Utility Model Content
[0005] In response to the technical problems existing in the background art, the utility model provides an urban drainage ditch dredging device, which solves the problem that the ordinary cleaning machines mentioned in the background art have obvious shortcomings in the real-time transportation of sewage. Although most machines can loosen sewage by stirring and digging, they lack a matching continuous conveying device, and the sludge and garbage cleaned up often accumulate around the work site or inside the pipe.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0007] A city drainage ditch dredging device includes a drive assembly, a mixing assembly, and a conveying assembly. The drive assembly has a housing at its upper end, the mixing assembly is mounted on the housing, and the conveying assembly is located inside the housing. The conveying assembly includes a transport pipe with a threaded guide wire fixed to its right side. The mixing assembly includes mixing blades, with the mixing blades also fixed to the right side of the transport pipe. The left side of the transport pipe is mounted inside the housing via a bearing bracket. A conveying motor is installed inside the housing and connected to the transport pipe via a transmission belt. A sewage pipe is located on the left side of the transport pipe and connected to the transport pipe via a rotary joint.
[0008] Preferably, the mixing assembly includes a support tube, which is fixed to the right side of the device housing, and the right side of the transport tube is disposed inside the support tube.
[0009] Preferably, the drive assembly includes a drive base, and multiple sets of drive wheels are disposed on the outer side of the drive base.
[0010] Preferably, the drive base is equipped with multiple drive motors, and the multiple drive motors are connected to the drive wheels.
[0011] Preferably, drive tracks are installed on the outer sides of the drive wheels on both sides.
[0012] Preferably, the drain pipe is fixed to the outer casing of the device and is in a non-rotatable state.
[0013] This utility model has the following advantages and beneficial effects:
[0014] In this utility model:
[0015] In actual use, the mixing blades and threaded guide wires work together to mechanically crush, mix and guide the waste without human contact, completely avoiding the exposure of operators to foul-smelling, sewage and germ environments, and solving the problem of harsh working environment in traditional manual cleaning.
[0016] In the conveying assembly, the transport pipe serves as the core channel, rotating under the drive of the conveying motor and transmission belt. Combined with the thrust of the threaded guide wire, it achieves continuous transport of waste. The bearing bracket ensures the stable operation of the transport pipe, and the rotary joint achieves a dynamic sealing connection between the transport pipe and the sewage pipe. This allows the sewage pipe to maintain a fixed posture without rotating with the transport pipe, facilitating the connection of the hose to directly transport waste to the designated collection point. This effectively solves the problems of difficult hose connection and easy waste leakage caused by the rotation of the pipe in ordinary machines. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0024] Example
[0025] like Figures 1-4 As shown, a city drainage ditch dredging device includes a drive assembly 1, a mixing assembly 3, and a conveying assembly 4. The drive assembly 1 has a device housing 2 at its upper end, the mixing assembly 3 is mounted on the device housing 2, and the conveying assembly 4 is located inside the device housing 2. The conveying assembly 4 includes a transport pipe 41, with a threaded guide wire 42 fixed to the right side of the transport pipe 41. The mixing assembly 3 includes mixing blades 32, with the threaded guide wire 42 located inside the mixing blades 32. The mixing blades 32 are fixed to the right side of the transport pipe 41, and the left side of the transport pipe 41 is installed inside the device housing 2 via a bearing bracket 45. A conveying motor 43 is installed inside the device housing 2, and the conveying motor 43 is connected to the transport pipe 41 via a transmission belt 44. A sewage pipe 47 is located on the left side of the transport pipe 41, and the sewage pipe 47 is connected to the transport pipe 41 via a rotary joint 46.
[0026] During operation, the mixing blades 32 rotate synchronously with the transport pipe 41, mechanically crushing and mixing silt, domestic waste, and rotten debris in the ditch, breaking up clumps of waste. While the mixing blades 32 crush the waste, the threaded guide wire 42 generates directional thrust through its spiral structure, guiding the loosened silt, waste, and other waste into the transport pipe 41. The transport pipe 41 forms a continuous transport path based on the spiral thrust of the threaded guide wire 42. The conveying motor 43 provides the power source for the entire conveying system, transmitting torque to the transport pipe 41 through the transmission belt 44. The bearing bracket 45 is used to fix the left side of the transport pipe 41, and its bearing structure reduces the frictional resistance when the transport pipe 41 rotates. The rotary joint 46 achieves a dynamic sealed connection between the transport pipe 41 and the sewage pipe 47, allowing the sewage pipe 47 to maintain a fixed posture without rotating with the transport pipe 41, facilitating the connection of the hose to directly transport waste to the designated collection point.
[0027] like Figures 1-4 As shown, the mixing assembly 3 includes a support tube 31, which is fixed to the right side of the device housing 2. The right side of the transport pipe 41 is located inside the support tube 31. Since the right side of the transport pipe 41 needs to bear the rotation of the mixing blades 32 and the threaded guide wire 42, and directly enters the drainage ditch to contact a large amount of dirt, it is prone to shaking or displacement under long-term stress. The support tube 31 provides rigid support for the right side of the transport pipe 41.
[0028] like Figures 1-4 As shown, the drive assembly 1 includes a drive base 11, with multiple sets of drive wheels 12 arranged on the outer side of the drive base 11. The drive base 11 and the multiple sets of drive wheels 12 enable flexible movement of the device. Multiple sets of drive motors 13 are arranged inside the drive base 11, and the multiple sets of drive motors 13 are respectively connected to the drive wheels 12. The multiple sets of drive motors 13 provide the power source for the device to move autonomously. Drive tracks 14 are installed on the outer side of the drive wheels 12 on both sides. In terms of ground adaptability, the drive tracks 14 significantly expand the contact area between the device and the ground, which can evenly distribute the weight of the device to a larger area and greatly reduce the pressure on the ground. When operating on muddy roads, soft soil or waterlogged areas around drainage ditches, the drive wheels 12 can effectively avoid getting stuck in mud or slipping.
[0029] The drain pipe 47 is fixed to the outer casing 2 of the device and is in a non-rotatable state. The non-rotatable drain pipe 47 provides a fixed channel for the discharge of sewage. There is no need to frequently adjust the position of the hose or use complex rotary sealing joints due to pipe rotation. This design completely eliminates the hidden dangers of hose entanglement and detachment in the rotating state, so that sewage can be directly transported to the designated collection equipment through the fixed channel.
[0030] When using the urban drainage ditch dredging device, first reliably connect the sewage pipe 47 to the external sewage collection hose, ensuring that the end of the hose is aligned with the designated collection device.
[0031] Start the drive motor 13 in the drive base 11, and drive the device slowly to the edge of the drainage ditch via the drive track 14. Adjust the device's posture so that the mixing component 3 is aligned with the area in the drainage ditch that needs to be cleared. The support pipe 31 provides rigid support to the right side of the transport pipe 41 to ensure that the mixing component 3 can stably penetrate into the drainage ditch.
[0032] The conveyor motor 43 is started, and the conveyor motor 43 drives the conveyor pipe 41 to rotate through the transmission belt 44. The mixing blade 32 on the right side of the conveyor pipe 41 rotates synchronously with it, and begins to mechanically crush and mix the clumps of silt, domestic waste, rotten debris and other materials in the ditch, breaking up large pieces of sewage. At the same time, the threaded guide wire 42 generates directional thrust with the help of the spiral structure, continuously guiding the loosened sewage into the conveyor pipe 41, forming a continuous conveying path by relying on the spiral thrust.
[0033] Because of its large contact area and low pressure, the drive track 14 can move stably in muddy or waterlogged areas around the drainage ditch, avoiding slipping or getting stuck in the mud. The dirt in the transport pipe 41 is pushed by the threaded guide wire 42, enters the non-rotatable sewage pipe 47 through the rotary joint 46, and is then transported to the collection equipment through the fixed hose. There is no need to worry about the hose getting tangled or falling off.
[0034] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
