The middle of the guide wheel 11 is movably connected with a guide push block 14, so that the mechanical energy can be driven by the driving motor 13, so that the machine can move freely in the pipeline to be dredged, and can pass the forward transmission and reverse rotation of the driving motor 13, so that the mechanical energy can be After the dredging of the inner cavity of the pipeline is completed, it automatically returns, which solves the problem of the return of the dredging equipment in the dark and damp dredging pipeline. The other end of the body 1 is fixedly connected with a connecting block 4, and the outer surface of one end of the connecting block 4 is opened. There is a high-pressure nozzle 5, a guide rod 6 is movably connected to the side of the other end of the connecting block 4, a spring 15 is movably connected to one end of the guide rod 6, and a telescopic rod 16 is movably sleeved in the middle of the guide rod 6, and one end of the telescopic rod 16 is movable The organic wheel 24 is connected, and the number of the guide rods 6 is two located on the left and right sides of the connecting block 4, respectively. By adding a guide mechanism in the middle of the machine, when the machine travels in the pipeline, when the front pipeline is turned, According to the change of the extension length of the telescopic rod 16, the mechanical energy can complete the automatic steering, which solves the problem that the pipeline turns around when the dredging equipment is dredging in the pipeline to be dredged, which causes the mechanical collision to the pipeline, and avoids the mechanical and the pipeline inside. When a collision occurs, the working life of the machine and the pipeline is guaranteed. A travel rod 7 is movably connected to the lower part of the connecting block 4. A limit hole 17 is opened in the middle of one side of the travel rod 7, and the limit block 18 is movably sleeved in the middle of the limit hole 17. , the middle part of the stroke rod 7 is movably sleeved with the adjustment rod 19, the middle part of the lower surface of the adjustment rod 19 is fixedly connected with a reversing button 20, and the lower part of the adjustment rod 19 is movably connected with a rotating rod 21. When traveling to the end of the pipeline, the reverse button 20 can be released to make the drive motor 13 reverse automatically, so that the dredging equipment can be automatically returned to the place where the dredging equipment is placed along the dredging pipeline, which solves the problem that the dredging equipment is working When reaching the end of the drainage pipe, due to the hole or filter at the connection of the pipe, the problem that the machine falls into the hole or filter ensures that the machine can return automatically, reduces the work damage of the machine, and ensures the work of the machine. Life, the rotation range of the rotating rod 21 is 0°-90°, and a wheel 24 is movably connected to the lower end of the rotating rod 21, so that the wheel 24 can be rotated, so that when the machine is working normally, the rotating rod 21 can reverse the When the turning button 20 is pressed and the wheel 24 cannot fall to the ground, the turning rod 21 rotates to a certain extent due to gravity, so that the reverse button 20 is released, the driving motor 13 automatically starts to reverse, the machine automatically starts to return, and the connecting block A beating motor 8 is fixedly connected to the other end of the beating motor 8, a beating disc 9 is movably connected to the other end of the beating motor 8, and a beating rod 2 is movably connected to one side of the beating disc 9. 2.

When the rotating end rotates, the beating disc 9 is rotated synchronously, the beating rod 22 is thrown out under the action of centrifugal force, and the beating ball 23 at the end of the beating rod 22 can automatically hit the stubborn dirt on the inner wall of the pipeline to be dredged One end of the hitting rod 22 is fixedly connected with a hitting ball 23, and the hitting range of the hitting ball 23 is adjusted by fixing bolts. When working, the dirt on the inner wall of the dredging pipeline can be hit first by the hitting mechanism, so that the dirt becomes loose, which is convenient for subsequent high-pressure water scouring and dredging, which solves the problem of the traditional dredging equipment due to stubborn dirt, which leads to automatic dredging. , the situation that the stubborn dirt cannot be completely removed occurs, which ensures the dredging quality of the dredging equipment on the inside of the pipe, and avoids the adverse effect of the accumulation of stubborn dirt on the drainage of the pipeline.

working principle:

During normal dredging: first manually remove the dirt at the mouth of the pipeline to be dredged, and adjust the size of the beating plate 9 through the fixing bolts, so that the side of the beating plate 9 is slightly smaller than the diameter of the pipe, and the beating ball 23 is rotated and thrown out The maximum range is greater than the diameter of the pipe, and the extension length of the drive box 3 is adjusted so that when the drive box 3 drives the machine forward, the center of the hitting disc 9 is just on the same horizontal line as the center of the pipe, and then the limit block 18 is used to adjust the stroke. The extension length of the rod 7 enables the wheel 24 below the rotating rod 21 to participate in the movement of the machine, and retracts the guide rod 6 inward, puts the machine into the pipeline to be dredged, then starts the machine and hits the motor 8 Rotate to make the hitting disc 9 rotate, the hitting ball 23 is thrown out by centrifugal force, and hits on the inner wall of the pipe, the dirt on the inner wall of the pipe is loosened, and the dredging water is sent to the inside of the body 1 through the water pipe 2, and then The dredging water is sprayed out through the high-pressure nozzle 5, and the loose dirt that has been beaten is dredged by the high-pressure water, so that the dirt falls off. At the same time, the motor 13 is driven to rotate, so that the driving wheel 10 rotates, and the machine moves forward for dredging. ;

When turning: When the guide rod 6 moves on the inner wall of the pipe, the spring 15 ejects the telescopic rod 16 outward, so that the wheel 24 outside the guide rod 6 moves in the inner cavity of the pipe. The wheel 24 moves along the inner wall of the pipe, and at the turning point, the extension length changes, and the guide push block 14 in the inner cavity of the drive box 3 pushes out or retracts the front end of the guide push block 14 according to the telescopic change of the guide rod 6, Make the guide wheel 11 turn, and then change the advancing direction of the machine, so that the machine can dredging along the pipeline;

When traveling to the end of the pipeline: when the machine is dredging, because the wheel 24 under the stroke rod 7 is under pressure when it moves forward, the stroke rod 7 is kept vertical, and the reverse button 20 at one end of the stroke rod 7 is continuously pressed. , the machine continues to move forward, and when the machine travels to the end of the pipe, the front end of the machine continues to move forward. When the lower end of the stroke rod 7 moves into the pipe, because the wheel 24 at one end of the stroke rod 7 is not stressed, the rotating rod 21 is caused by Gravity bends, so that the reversing button 20 is released, the driving motor 13 in the driving box 3 is reversed, and the machine is returned along the original path.
