[0020] Please refer to Figures 1-3 , the dike filling base mud discharge device in this embodiment includes a horizontal pipe 1. A fixed disk 2 is fixedly connected to the rear end of the horizontal pipe 1. The front end surface of the fixed disk 2 is horizontally rotatably connected to a rotating shaft 3 coaxial with the horizontal pipe 1. The outer surface of the rotating shaft 3 is fixedly connected along its length direction with conveying blades 4 adapted to the inner diameter of the horizontal pipe 1.

[0021] The rear end surface of the fixed disk 2 is fixedly connected with a device box 9. Inside the device box 9, a motor 10 is fixedly connected. The output shaft of the motor 10 rotatably penetrates the fixed disk 2 and is fixedly connected to the rear end of the rotating shaft 3. The rear end of the lower surface of the horizontal pipe 1 is communicated with a connector 11, and the other end of the connector 11 is communicated with a discharge pipe 12.

[0022] In this embodiment, when the device is in use, the front end of the horizontal pipe 1 of the device is directly inserted into the silt and the motor 10 is operated. After the motor 10 is started, its output shaft rotates to drive the rotating shaft 2 fixedly connected to its output shaft to rotate. During the rotation of the rotating shaft 2, the conveying blades 4 on its surface will drive the silt to move towards the rear end of the horizontal pipe 1 of the device. Finally, the silt will be discharged through the discharge pipe 12 at the bottom of the rear end of the horizontal pipe 1. The structure of the device is suitable for pumping silt, and the impurities in the silt will not cause too much damage to the device, enabling the device to operate for a long time and improving the efficiency of the mud discharge work.

[0023] The front end of the horizontal pipe 1 of the device is in an inclined plane, enabling it to be inserted into the silt more quickly and deeply.

[0024] Furthermore, a plurality of support columns 6 arranged along the radial direction of its cross-section are fixedly connected to the inner surface of the front end of the horizontal pipe 1. The inner ends of the plurality of support columns 6 are fixedly connected with a support ring 5, and the rotating shaft 3 is rotatably connected to the inside of the support ring 5.

[0027] Furthermore, a crushing blade 7 is fixedly connected to the outer surface of the rotating shaft 3 and in front of the support ring 5.

[0028] In this embodiment, the crushing blade 7 also rotates as the rotating shaft 2 continues to rotate. It will break up large mud blocks at the front end of the device to facilitate their entry into the horizontal pipe 1 of the device.

A front holding handle 14 is horizontally fixedly connected to the upper surface of the connecting seat 13, and a rear holding handle 15 is vertically fixedly connected to the rear end surface of the device box 9.

[0030] In this embodiment, when the device is in use, people can hold the front holding handle 14 and the rear holding handle 15 with both hands to control the device.

[0031] Furthermore, anti-slip sleeves 16 are sleeved on the outer surfaces of the front holding handle 14 and the rear holding handle 15.

[0032] In this embodiment, the anti-slip sleeves 16 achieve an anti-slip effect and ensure the stability of the device during use.

[0033] The working principle and usage process of the present utility model: After the present utility model is installed, when the device is in use, the front end of the horizontal pipe 1 of the device is directly inserted into the silt and the motor 10 is operated. After the motor 10 is started, its output shaft rotates to drive the rotating shaft 2 fixedly connected to its output shaft to rotate. During the rotation of the rotating shaft 2, the conveying blades 4 on its surface will drive the silt to move towards the rear end of the horizontal pipe 1 of the device. Finally, the silt will be discharged through the discharge pipe 12 at the bottom of the rear end of the horizontal pipe 1. The structure of the device is suitable for pumping silt, and the impurities in the silt will not cause excessive damage to the device, enabling the device to operate for a long time and improving the efficiency of the mud discharge work.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
