Description

Technical Field

[0001] This application belongs to the field of culvert dredging technology, specifically relating to a sludge stirring device for culvert dredging. Background Technology

[0002] In urban infrastructure, culverts serve as a crucial component of drainage systems, playing a vital role in discharging rainwater and sewage. However, due to long-term use and erosion from the natural environment, culverts often accumulate large amounts of silt and debris. This not only affects the drainage efficiency of the culverts but can also lead to serious problems such as blockages and overflows, causing inconvenience to the urban environment and residents' lives.

[0003] Due to the limited space in culverts, traditional culvert dredging methods mostly rely on manual cleaning. In the conventional manual cleaning process, workers first insert a rod-shaped tool into the silt, and then stir the silt by lifting and pulling the tool up and down while driving it to rotate. This causes the solid particles and water in the silt to mix evenly, which is beneficial for subsequent treatment and discharge. At the same time, it also helps to reduce resistance during the dredging process and improve dredging efficiency.

[0004] The inventors discovered that manually stirring sludge is inefficient, labor-intensive, and poses a safety hazard to workers, hindering the actual work. Utility Model Content

[0048] Please refer to the following: Figures 1 to 10 The sludge agitation device for culvert dredging provided in this application will now be described. The sludge agitation device for culvert dredging proposed in this application includes a housing 1, a main shaft 2, and a drive assembly 3.

[0049] The box 1 is for workers to hold and is fixed directly above the sludge to be stirred;

[0050] The main shaft 2 is located on the lower side of the housing 1, with its axis parallel to the vertical direction, for insertion into the silt. A helical blade 21 is fixedly mounted on the outer periphery of the main shaft 2, so that when the main shaft 2 rotates, the helical blade 21 drives the silt to move vertically.

[0051] The drive assembly 3 is fixedly installed inside the housing 1 and is connected to the main shaft 2 for transmission. The drive assembly 3 is used to drive the main shaft 2 to move in the up and down direction, and at the same time drive the main shaft 2 to rotate around its own central axis to agitate the sludge.

[0052] In this embodiment, the housing 1 is used by workers to hold and carry it, fixing it directly above the sludge to be stirred. In this state, the lower end of the main shaft 2 is inserted into the sludge, and then the drive assembly 3 is activated, which allows the main shaft 2 to move vertically and rotate simultaneously. During the movement and rotation of the main shaft 2, the sludge will rise axially and spirally under the action of the spiral blades 21, thereby achieving thorough stirring of the sludge.

[0053] The sludge agitation device for culvert dredging provided in this embodiment, compared with the prior art, can realize the agitation of sludge in an automated manner, so as to reduce labor intensity, ensure work efficiency, and ensure the safety of workers.

[0054] In some embodiments, such as Figures 4 to 8 As shown, a through hole 11 communicating with the interior is provided on the lower side of the housing 1. When the housing 1 and the spindle 2 are assembled, this through hole 11 and the spindle 2 are coaxially arranged.

[0055] Based on the foregoing, the drive assembly 3 includes a guide cylinder 31 and a rotating motor 32.

[0056] The guide cylinder 31 is fixedly installed on the inner bottom surface of the housing 1 and is coaxially connected with the through hole 11.

[0057] The inner circumferential wall of the guide cylinder 31 is provided with an internal thread, and a transmission screw 311 that is adapted to the internal thread and is threadedly connected to the guide cylinder 31 is inserted into the guide cylinder 31.

[0058] The lower end of the transmission screw 311 is coaxially connected to the upper end of the main shaft 2 (the specific connection method can be welding, detachable connection, etc.). The upper end of the transmission screw 311 is connected to a ball bearing 313 through a connecting rod 312 coaxially arranged with it. Specifically, the upper end of the transmission screw 311 has a connecting rod 312 coaxially arranged with it, and the end of the connecting rod 312 facing away from the transmission screw 311 is coaxially connected to a ball bearing 313.

[0059] The rotating motor 32 is fixedly installed on the inner side of the housing 1, and its power output axis is parallel to the horizontal plane.

[0060] The power output end of the rotary motor 32 has a connecting arm 4 extending radially outward, and a transmission arm 5 is hinged to the connecting arm 4; the hinge axis of the transmission arm 5 is parallel to the power output axis of the rotary motor 32, and the swing end of the transmission arm 5 has a mounting sleeve 51 that is hinged to the ball 313.

[0061] In actual use, by turning on the rotating motor 32, the connecting arm 4 can swing around the power output shaft of the rotating motor 32, thereby driving the swing and lifting of the transmission arm 5. In this way, by means of the ball joint of the ball 313 and the mounting sleeve 51, the transmission screw 311 can be raised and lowered. At the same time, due to the threaded connection between the transmission screw 311 and the guide cylinder 31, this linear drive can be converted into a spiral advance.

[0062] To ensure smooth operation between the guide cylinder 31 and the transmission screw 311, lubricating oil needs to be added to the guide cylinder 31 regularly during actual use. Since the guide cylinder 31 is located inside the housing 1, and the interior space of the housing 1 is a closed space, the aforementioned oiling process can be carried out stably and reliably.

[0063] In some embodiments, such as Figure 7 and Figure 8 As shown, the connecting arm 4 has multiple mounting holes 41; the multiple mounting holes 41 are spaced apart along the length direction of the connecting arm 4, and the axial direction of each mounting hole 41 is parallel to the power output axis of the rotating motor 32.

[0064] The transmission arm 5 is provided with a mating hole 52 suitable for communicating with any of the mounting holes 41; based on this, the transmission arm 5 also includes a connecting bolt 53 and a connecting nut 54.

[0065] The connecting bolt 53 is adapted to be inserted into the interconnected mounting hole 41 and mating hole 52.

[0066] The connecting nut 54 is adapted to be threadedly connected to the connecting bolt 53, and it mates with the head of the connecting bolt 53 to abut against the outer surfaces of the transmission arm 5 and the connecting arm 4 respectively, thereby restricting the separation of the transmission arm 5 and the connecting arm 4.

[0067] By adopting the above technical solution, the distance between the connecting hole 52 and different mounting holes 41 can be changed, thereby adjusting the linear movement distance of the main shaft 2 to adapt to silt environments of different depths.

[0068] It should be added that, such as Figure 7As shown, there is also a gasket between the connecting nut 54 and the transmission arm 5. This gasket is made of a material with a different coefficient of friction to prevent the connecting nut 54 and the connecting bolt 53 from separating due to the swing of the transmission arm 5, thereby improving the structural stability of the device.

[0069] In some embodiments, such as Figure 4 As shown, the box 1 adopts an open structure that runs through the horizontal direction, and the open surface of the box 1 has a waterproof plate 12 suitable for closing the through opening, so as to facilitate the adjustment, maintenance and replacement of the components inside the box 1.

[0070] In some embodiments, such as Figure 1 and Figure 3 As shown, the outer side of the tank 1 has a mounting base 13, on which a sewage pump 6 is fixedly installed to facilitate the directional discharge of sewage from the lower side of the tank 1, so as to avoid the sewage affecting the sludge stirring operation.

[0071] In some embodiments, such as Figure 1 and Figure 3 As shown, the sewage pump 6 is connected to a sewage discharge pipe 61, which allows the sewage pump 6 to discharge sewage to a distant location. Based on this, the outer side of the housing 1 also has a reinforcing member 14 located on the upper side of the mounting base 13 and connected to the sewage pump 6, to prevent the sewage pump 6 from separating from the housing 1 due to vibration, thus improving the structural stability of the device.

[0072] In some embodiments, such as Figure 1 As shown, a mud-proof sleeve 7 is fitted around the outer periphery of the main shaft 2. The mud-proof sleeve 7 is connected to the housing 1 through a detachable connection structure 8, so that different lengths of mud-proof sleeve 7 can be replaced by disassembly and assembly during actual use to adapt to different silt environments.

[0073] In some embodiments, such as Figures 1 to 5 As shown, the detachable connection structure 8 includes a fixed sleeve 81 and a plug-in sleeve 82.

[0074] The fixing sleeve 81 is fixedly connected to the lower end face of the housing 1 and is coaxially arranged with the main shaft 2.

[0075] The plug sleeve 82 is fixedly connected to the upper end of the mudproof sleeve 7 and is coaxially arranged with the mudproof sleeve 7.

[0076] In actual use, the plug sleeve 82 can be inserted into the inside of the fixed sleeve 81, and the insertion part of the plug sleeve 82 has an alignment hole 821 communicating with its interior; correspondingly, the fixed sleeve 81 is fixedly provided with a positioning nut 811 that is coaxially communicating with the alignment hole 821, and the positioning nut 811 is threadedly connected with a limiting bolt 812 that is suitable for insertion into the alignment hole 821, so as to limit the relative movement of the fixed sleeve 81 and the plug sleeve 82.

[0077] In some embodiments, such as Figure 10 As shown, the mud-proof sleeve 7 includes multiple mud-blocking strips 71 and multiple reinforcing rings 72.

[0078] Multiple mudguards 71 ​​are spaced apart along the circumference of the main shaft 2. Each mudguard 71 is connected to the housing 1 through the aforementioned detachable connection structure 8, and the length direction of each mudguard 71 is parallel to the axial direction of the main shaft 2.

[0079] Multiple reinforcing rings 72 are fitted around the outer periphery of the main shaft 2 and are spaced apart along the axial direction of the main shaft 2; each reinforcing ring 72 is connected to multiple mudguards 71 ​​to limit the horizontal movement of the mudguards 71 ​​relative to the main shaft 2, that is, to limit the damage to the mudguards 71.

[0080] In some embodiments, such as Figure 1 and Figure 3 As shown, the upper surface of the box 1 has a handle 15 for workers to hold, so that the operator's hands can be placed on the upper side of the box 1 to avoid the adverse effects of sewage immersion.

[0081] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
