Description

Technical Field

[0001] The invention relates to the technical field of sewer cleaning, and in particular to a sewer silt removal device. Background Art

[0002] Sewers are an important part of urban infrastructure, used to discharge sewage and rainwater. They mainly include main pipes and branch pipes, which are responsible for transporting sewage from the source to treatment facilities or discharge points.

[0003] Over time, municipal sewage pipes may age and corrode, causing the inner wall of the pipe to become rough and easily accumulate sludge, thereby increasing the risk of pipe blockage. In addition, during the construction of municipal sewage pipes, if the quality of the materials used is not up to standard or the construction process is not standardized, the inside of the pipe will be uneven and prone to uneven areas, which will then accumulate silt and increase the risk of pipe blockage.

[0004] Therefore, municipal personnel need to use dredging equipment to dredge the sewers regularly. The dredging equipment is generally composed of a walking mechanism and a mechanism for crushing sludge, but the crushed sludge will still remain in the sewer, and a corresponding pump truck is needed to suck the crushed sludge out of the sewer. However, the sludge is scattered throughout the sewer, and the adsorption end of the sludge pipe needs to adsorb various points in the sewer, so the dredging process is complicated, takes a long time, and is inefficient. Summary of the invention

[0005] The main purpose of the present invention is to provide a sewer dredging device, wherein the crushing and conveying device can crush the coagulated sludge and convey the crushed sludge back to the shell, while the silt discharge device can convey the sludge in the shell out of the sewer, thereby realizing the integrated operation of crushing and conveying the sludge and improving the dredging efficiency.

[0006] To achieve the above object, the technical solution adopted by the present invention is: A sewer silt removal device comprises a remote-controlled mobile platform, a shell is fixed on the remote-controlled mobile platform, a silt removal device is arranged in the shell, the shell is provided with an internal rotating drive device, a crushing and conveying device is arranged at the driving end of the rotating drive device, and the crushing and conveying device, driven by the rotating drive device, crushes the silt at multiple points and conveys it into the shell.

[0007] Furthermore, the crushing and conveying device includes a shaft body fixedly connected to the driving end of the rotating drive device, a connecting part is fixed at one end of the shaft body, a conical drill bit is fixed on one side of the connecting part, a plurality of crushing blades are also arranged on the periphery of the connecting part, and a plurality of fan blades for conveying sludge are also arranged on the shaft body, and the plurality of fan blades are located between the rotating drive device and the crushing blades.

[0009] Furthermore, a plurality of the crushing blades are arranged at equal angles with the axis of the shaft body as the center, and the crushing blade comprises a handle and a blade tip fixedly connected to the handle, and the handle is fixed on the connecting portion.

[0010] Furthermore, the angle between the tool tip and the tool handle is 115 degrees to 160 degrees and the tool tip points to the conical drill bit.

[0011] Furthermore, a plurality of the fan blades are arranged at equal angles with the axis of the shaft body as the center, and the fan blades are inclined toward the rotation driving device and the inclination angle is 15 degrees to 30 degrees.

[0012] Furthermore, one end of the shell has a cover body, the fan blades are located inside the cover body, and the conical drill bit and the crushing blade are located outside the cover body.

[0017] When the crushing and conveying device of the present invention crushes the sludge, the conical drill bit drills a hole in the blocked sludge first, so when the crushing blade crushes the sludge, the sludge can move toward the hole drilled by the conical drill bit, so that the sludge has enough space to deform during crushing, thereby improving the crushing efficiency of the sludge.

[0018] The guide groove on the conical drill bit of the present invention can guide and convey the crushed sludge, so that the crushed sludge by the conical drill bit can move along the guide groove and escape from the hole drilled by the conical drill bit.

[0019] The blade tip of the present invention has an angle with the blade handle, and the blade tip points to the conical drill bit, so the crushing blade can gather the crushed sludge, and as the remote-controlled mobile platform moves forward, the sludge will enter the fan blade area due to the squeezing of subsequent sludge.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figure 1-5 As shown, a sewer silt removal device includes a remote-controlled mobile platform 4. The remote-controlled mobile platform 4 is a prior art and will not be described in detail here. A shell 1 is fixed on the remote-controlled mobile platform 4. A silt removal device is arranged in the shell 1. The silt removal device includes a sludge pump 6 located in the shell 1. The silt removal end of the sludge pump 6 is connected to a pipe 2. The discharge end of the pipe 2 passes through the shell 1. The shell 1 is provided with an internal rotary drive device 7. A crushing and conveying device 5 is arranged at the driving end of the rotary drive device 7. The crushing and conveying device 5, driven by the rotary drive device 7, crushes the sludge at multiple points and conveys it to the shell 1, and the silt removal device can convey the sludge waste in the shell 1 to the outside of the sewer for personnel to handle it.

[0029] In this embodiment, if Figure 3 and Figure 4As shown, the crushing and conveying device 5 includes a shaft body 501 fixedly connected to the driving end of the rotary drive device 7, one end of the shaft body 501 extends out of the shell 1, and a connecting portion 504 is fixed to the end, a conical drill bit 505 is fixed to one side of the connecting portion 504, and the conical drill bit 505 is spirally provided with a guide groove 506 along its conical surface, and a plurality of crushing blades 503 are also arranged on the periphery of the connecting portion 504, and the plurality of crushing blades 503 are arranged at equal angles with the axis of the shaft body 501 as the center, and the crushing blade 503 includes a handle 5031 and a blade tip 5032 fixedly connected to the handle 5031. The handle 5031 and the blade tip 5032 are both made of stainless steel. The handle 5031 is fixed on the connecting part 504. The angle between the blade tip 5032 and the handle 5031 is 115 degrees to 160 degrees, and the blade tip 5032 points to the conical drill bit 505. A plurality of blades 502 for conveying sludge are also arranged on the shaft body 501. The plurality of blades 502 are located between the rotating drive device 7 and the crushing blade 503. The plurality of blades 502 are arranged at equal angles with the axis of the shaft body 501 as the center. The blades 502 are inclined toward the rotating drive device 7 and the inclination angle is 15 degrees to 30 degrees.

[0030] When the silt removal vehicle is working, a person puts it into the sewer, enters the sewer, and extends the pipe 2 out of the sewer pipe to connect with the silt removal vehicle on the ground. The wires of the sludge pump 6 and the rotary drive device 7 extend out of the sewer pipe along with the pipe 2 and are connected to the power supply equipment of the silt removal vehicle on the ground.

[0031] During silt removal, the rotary drive device 7 drives the shaft 501 to rotate, thereby driving the conical drill bit 505, the crushing blade 503 and the fan blade 502 to rotate. Then, when the remote control mobile platform 4 moves under the control of the personnel and causes the conical drill bit 505 and the crushing blade 503 to contact the silt, the conical drill bit 505 can drill holes in the blocked silt, and the crushing blade 503 can crush the corresponding area of ​​the silt with the conical drill bit 505 as the center. During the crushing process, since the sharp end of the conical drill bit 505 is located outside the crushing blade 503, when the crushing blade 503 crushes the silt, the conical drill bit 505 has drilled a hole in the blocked silt, so the silt crushed by the crushing blade 503 can move toward the hole drilled by the conical drill bit 505, so that the silt has enough space to deform during crushing, thereby improving the crushing efficiency. In addition, the conical drill bit 505 The guide groove 506 can guide and convey the crushed sludge, and the angle between the tip 5032 of the crushing blade 503 and the handle 5031 is 115 degrees to 160 degrees, and the tip 5032 points to the conical drill bit 505, so the crushing blade 503 as a whole can play a role in gathering the crushed sludge, and as the remote-controlled mobile platform 4 moves forward, the sludge will enter the fan blade 502 area, and since one end of the shell 1 has a cover body 3, the fan blade 502 is located in the cover body 3, and the conical drill bit 505 and the crushing blade 503 are located outside the cover body 3, a sludge conveying channel is formed between the several fan blades 502 and the cover body 3, and as the fan blades 502 rotate, they can convey the sludge into the shell 1. At this time, the sludge pump 6 works and can discharge the sludge in the shell 1 into the sewer through the pipe 2. When the fan blades 502 rotate, the fan blades 502 can also crush the sludge.

[0032] Working principle: when the crushing and conveying device 5 is operating on the sludge, the conical drill bit 505 drills a hole in the blocked sludge first, so when the crushing blade 503 is crushing the sludge, the sludge can move toward the hole drilled by the conical drill bit 505, so that the sludge has enough space to deform during crushing, thereby improving the crushing efficiency. In addition, the guide groove 506 on the conical drill bit 505 can guide and convey the crushed sludge, and the tip 5032 of the crushing blade 503 and the handle 5031 are connected to each other. The angle is 115 to 160 degrees, and the blade tip 5032 points to the conical drill bit 505, so the crushing blade 503 as a whole can gather the crushed sludge, and as the remote-controlled mobile platform 4 moves forward, the sludge will enter the fan blade 502 area, and a sludge conveying channel is formed between the fan blades 502 and the cover body 3, and as the fan blades 502 rotate, the sludge can be conveyed into the shell 1. At this time, the sludge pump 6 works and can discharge the sludge in the shell 1 into the sewer through the pipe 2.
