A closing member for blocking the gap between the collecting box and the side wall of the groove is provided on the collecting box. Although the above patent can clean the silt by moving the push plate and the collecting box, the silt is prone to secondary precipitation if it accumulates for too long, resulting in a larger hardness of the silt, which causes the push plate to be stuck in the silt. In this case, the staff needs to use tools to loosen and break the silt before continuing the dredging operation.

[0004] Therefore, it is necessary to provide a dredging device for water conservancy projects that can automatically break up the silt. Utility Model Content

[0005] In order to overcome the disadvantage that although the above patent can clean the silt by moving the push plate and the collection box, the silt accumulation for too long may easily lead to secondary sedimentation of the silt, making the silt hard, which may easily cause the push plate to be stuck by the silt, resulting in low dredging efficiency, the utility model provides a dredging device for water conservancy projects that can automatically break up the silt.

[0006] The utility model is realized through the following technical means: a dredging device for water conservancy projects, comprising a mounting shell, a servo motor, a connecting frame, a spiral feed plate, a collecting chamber, a conduit and a mud pump, wherein a servo motor is mounted on the upper part of the mounting shell, a spiral feed plate is fixedly connected to the output shaft of the servo motor, the spiral feed plate rotates in the mounting shell, a connecting frame is fixedly connected to the bottom of the mounting shell, a conduit is connected to the upper right side of the mounting shell, a mud pump is mounted in the middle of the conduit, and a stirring paddle is also included, a stirring paddle is fixedly connected to the output shaft of the servo motor, and the stirring paddle is located below the spiral feed plate.

[0007] In one of the embodiments, it also includes an arc-shaped fixing plate, a fixing block and a screw rod.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] Embodiment 1, a dredging device for water conservancy projects, see Figure 1-Figure 4 As shown, it includes a mounting shell 1, a servo motor 2, a connecting frame 3, a spiral feed plate 5, a collecting chamber, a conduit 7, a mud pump 8, an agitator 4 and a scraper 15. The servo motor 2 is provided on the upper part of the mounting shell 1 by bolt connection. The spiral feed plate 5 is fixedly connected to the output shaft of the servo motor 2. The spiral feed plate 5 rotates in the mounting shell 1. The connecting frame 3 is provided on the bottom of the mounting shell 1 by welding. The conduit 7 is connected to the right side of the upper part of the mounting shell 1. The mud pump 8 is installed in the middle of the conduit 7. The agitator 4 is fixedly connected to the output shaft of the servo motor 2. The agitator 4 is located below the spiral feed plate 5. The scraper 15 is fixedly connected to the output shaft of the servo motor 2. A tightening thread 16 is opened in the right part of the conduit 7.

[0022] When the device is to be used, the staff places the device at the designated position so that the spiral feed plate 5 is immersed in the silt. Then the staff connects the water pipe to the conduit 7 by tightening the thread 16 so that the water pipe is located on the river bank, thereby preventing the discharged silt from falling back into the river channel due to the large distance between the conduit 7 and the river bank. Then the staff starts the servo motor 2, and the output shaft of the servo motor 2 drives the stirring paddle 4 to rotate, so that the stirring paddle 4 can break up the silt, thereby facilitating the discharge of the silt and preventing the silt from clogging the conduit 7. At the same time, the output shaft of the servo motor 2 drives the spiral feed plate 5 and the scraper plate 15 to rotate, and the spiral feed plate 5 drives the broken silt to move upward. The staff then starts the mud pump 8 so that the mud pump 8 extracts the silt, and the silt is discharged from the water pipe through the mud pump 8 through the conduit 7. The scraper plate 15 scrapes off the silt on the inner wall of the installation shell 1 to prevent the silt from sticking to the inner wall of the installation shell 1, which is inconvenient for the staff to clean. After completing the dredging work, the staff can turn off the servo motor 2.

[0023] Example 2, based on Example 1, see Figure 1 and Figure 3 As shown, it also includes an arc-shaped fixing plate 9, a fixing block 101 and a screw 10. The right end of the catheter 7 is symmetrically slidably provided with an arc-shaped fixing plate 9, and the left and right parts of the arc-shaped fixing plate 9 are both threadedly provided with screws 10. A fixing block 101 is slidably provided on the screw 10, and the fixing block 101 is threadedly connected to the screw 10.

[0024] When the diameter of the connected water pipe is larger than the conduit 7, the staff rotates the fixing block 101, and then rotates the screw 10 to drive the two arc-shaped fixing plates 9 to move back to back, so that the distance between the two arc-shaped fixing plates 9 becomes larger. Then the staff puts the water pipe on the conduit 7, and then reverses the screw 10 to drive the arc-shaped fixing plates 9 to move toward each other, so that the arc-shaped fixing plates 9 clamp the water pipe. Then the staff reverses the fixing block 101 to further fix the water pipe with the fixing block 101 to prevent the water pipe from falling off the conduit 7.

[0025] See also Figure 1 and Figure 4 As shown, it also includes a support frame 11, a connecting seat 12, a three-way wheel 13 and an elastic member 14. The support frame 11 is arranged in the middle of the mounting shell 1 by welding, and a plurality of connecting seats 12 are evenly and slidably arranged at the lower part of the support frame 11. The three-way wheels 13 are installed on both the left and right parts of the connecting seat 12, and an elastic member 14 is connected between the connecting seat 12 and the support frame 11.

[0026] When the device is to be moved, the worker pushes the mounting shell 1 to rotate the three-way wheel 13 to drive the device to move, and the elastic member 14 is deformed accordingly, which makes it easier for the worker to move the device, thereby cleaning the silt in different places and improving work efficiency.

[0027] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
