[0047] As Figures 1-7 shown, a pipe dredging device with foldable wheel legs includes:

[0048] A support mechanism, the support mechanism includes a support plate 1, a diaphragm pump 2 is arranged on one side of the support plate 1, and a sewage discharge pipe 3 is connected to one end of the diaphragm pump 2;

[0049] A wheel leg walking mechanism, the wheel leg walking mechanism includes a plurality of support legs 4, the plurality of support legs 4 are hinged to the other side of the support plate 1 through a U-shaped seat 5, and a driving wheel is arranged at the end of the plurality of support legs 4 away from the support plate 1;

[0050] A stirring and dredging structure, one end of the stirring and dredging structure is connected to the support plate 1 through a hinge 29, and the stirring and dredging structure is connected to the diaphragm pump 2.

[0051] Specifically, the stirring and dredging structure folds and contracts the volume together with the support legs through the hinge 29, and in the unfolded state, it automatically contacts the ground by relying on gravity. At the same time, because it relies on gravity, the dredging depth is constant and automatically deepens. The support legs 4 and the support plate 1 can be folded and stored through the U-shaped seat 5, which is convenient for the device to enter a narrow space. The driving wheel provides power to drive the device to move forward. The stirring and dredging structure breaks up and crushes the silt to facilitate suction.

[0052] When in use, the device in the storage state is vertically passed through a shaft or inspection well and then unfolded in the drainage pipe. The driving wheel provides power to move forward. During the movement, the stirring and dredging structure cooperates with the diaphragm pump 2 to clean the silt, and the silt is pumped to the ground for unified treatment.

[0053] In this embodiment, eight L-shaped baffles 6 are arranged on one side of the support plate 1, and four support legs 4 are arranged. A limiting groove is formed between every two L-shaped baffles 6 and one support leg is located in the limiting groove.

[0054] Specifically, the support legs 4 are restricted from both sides by the L-shaped baffles 6 to prevent the support legs 4 in the unfolded state from being distorted and skewed under force during movement.

[0055] Further, the support legs 4 include two first support legs and two second support legs. The U-shaped seat 5 is fixed by countersunk screws. The deviation angle of the first support leg from the midline of the support plate 1 is 20°, and its length is 600 mm. The deviation angle of the second support leg from the midline of the support plate 1 is 15.787°, and its length is 800 mm. This not only avoids the interference between the first support leg and the second support leg in the folded state and further compresses the space in the folded state, but also provides sufficient stable support for the device in the unfolded state.

[0056] In this embodiment, the drive wheel includes:

[0057] A first hollow square tube 7.1 and a second hollow square tube 7.2, arranged side by side at the end of the support leg 4. A drive motor 8 is arranged inside the first hollow square tube 7.1;

The spiked wheel 11 is rotatably connected to the bolt assembly, the spiked wheel 11 is located between the two clamping plates 9, and the first bevel gear 12 is sleeved on the bolt assembly 10.
